With most of the prior art parts washing systems, the part~ to be cleaned were either hand carried to the washer or placed in a carrier and tran~ported to the washer in the carrier. In both cases, however, the parts would have to be hand loaded into the wa~her for cleaning which ls labor lntensive and time consuming.
What has been needed and heretofore unavailable is an effective parts conveying 6ystem integral with the washer which minimizes the time and effort reguired to clean automotive part~ and the like. The present invention satisfies this need.
~Ll~EYL~ HE INV$NTION
Thi~ lnventlon 1B dlrected to a washing 6y6tem and particularly to an improved conveying cystem for tran~porting automotlve parts and the like to and from a washing apparatus.
In accordance with the lnventlon, the wa~bing ~y~tem lnclude~ a wa~her having a cabinet, a washing chamber within th- caSinet, a door in the front of the cablnet to provide acce~s to the w~hing chamber, and mean~ to ~pray cleaning fluld on the urface of article~ placed withln the washing cbamber.
Integral with the wa~hing ~ystem i~ an improved conveying ~y6tem for transporting dirty art~cles to be cleaned from a distant location, such as an automotive ~hop work statlon, to the washer, loadlng the dlrty artlcles into the washer, unloading the cleaned articIe~ from the washer, and then tran~porting cleaned articl-~ ~ro~ the waaher back to a ~i~tant location, ~uch a- to the work ~tation or to ~torage.

the lower port~on of a washing chamber 14, horizontal spray manifold lS underneath the support frame 12, and a plurality of upstanding ~pray manifold~ 16 and 17 extend~ng therefro~ are disposed within the washing chamber 14 to spray cleaning fluid toward automotive parts or other articles supported on tabl~ 12. An access door 18 i8 provided in cabinet 11 to allow for the loading and unloading of the washer 10.
The conveyor system embodying features of tbe invention includes a mobile carrier or trolley 20 having secured to the upper surface thereof parallel track or guide means 21 and 22 which are adapted to receive a wheeled article support tray or ba~ket 23.
Matching track or guide ~eans 24 and 25 are secured to lS the upper ~urface o~ support frame or turntable 12 disposed with~n the washing chamber 14 and are adapted to receive the wheeled article ~upport tray or ba~ket 23 from the trolley 20.
The trolley 20 i~ pu~hed by means o~ handle 26 to a distant location, ~uch a~ a work station at an automotive repair ~hop, and one or more parts to be cleaned are placed ~n the wheeled tray or ba~ket 23, which iB detachably fixed onto the trolley ZO by a latching ~eans (not ~hown), and then the trolley 20 is pushed to the washer 10 and positioned in front of open door 18 with the track or guide ~eans 21 and 22 al~gned with the track or guide means 24 and 25 securely mounted on the turntable 12. In this manner, the parts to be cleaned can be loaded lnto the wa6hing chamber 14 by pu~hing the wheeled tray 23 containing the dirty parts from the trolley or carrier Z0 onto the turntable 12 in the wa~hing chsmber 14. The trolley 20 is pulled b~ck ~n the acce~ door 18 in the front o~ cabinet 11 can be pulled down to a closea position and the washing cycle can be then ~tarted. To unload the cleaned part~
from the wa~her 10, the door 18 i~ lifted upwardly to an open po~ition and the wheeled tray 23 ls pulled out o~ ch~mber ~4 onto the trolley 20. A lat-h~ng ~ean6 (not 6hown) i8 engaged B0 that the wheeled tray 23 w~l not ~ove on tracks 21 and 22 wh~e the trolley 20 i8 being moved. With the tray 23 ~ixed, the clean parts may then be transported back to the work station or, if de~ired, to ~ storage area where the clean parts may be removed from the wheeled tray 23.
As shown more clearly in ~IG. 2, cart or trolley 20 is provided with a drain pan 27 for capturing fluid and other material which may drain or fall from the ob~ects placed in the wheeled tray or basXet 23 ~nd directlng the material through opening 28 into ~ collecting conta~ner or pail 30 dlsposed on A
lower shelf 31 Or cart 20.
The cleaning solution ~prayed on the articles in th~ washing cha~er 14 drain~ down inclined surface 32 into a worXing tank 33 di~po~ed ln the lower portion o~ the cabinet 11 beneath the support ~rame 12.
A particulate capturing container 34 is provided within the worklng tank 33 having one or more openings or a screen 35 in the wall~ thereof ~o that the cleaning solution may pass through ~uch walls when the container 34 i5 li~ted ~rom the wor~ing t~nk 33, yet the 601id partlculate mater~al 36 wh~ch 6epar~tes fro~
thQ clQaning solutlon i~ ret~ned ther~n. Th~
turntable 12 must be lifted from gp~ndle 13 ~nd e~ther removed from the chamber or leaned against ~ ~ar wall thereof 60 that the container 34 can be lifted through opening 37, removed ~rom the wa~her 10, and the sludge 36 and other particulate therein di carded. As in~i¢at-d ~n PIG8. 2, 3 and 6, a handle 38 i~
preferably provided on the container 34 ~o that it may be lifted by mQan~ o~ a hook 39 on a cable 40 wound on a pulley 41 operated by crank 42. When the container 34 i6 lifted by the hook 39 out o~ the working tank 33, , . . .

the cart or trolley 20 may be pu~hed forwardly eo that the leading edges o~ ra~ls 21 ~nd 22 are under the contalner 34 Container 34 can then be lowered onto the rail~ 21 and 22 and then be manually pulled ~urther S bacX onto ths ra~ls If desired, wheel~ can be provided on container 34 to facilitate movement on the rails 21 and 22 When properly positioned on the rail~
21 and 22, the ~lidable bottom 43 of the container 34 mAy be pulled open 80 that the 601ids 36 and other material therein will drop into the drain pan 27, through discharge opening 28 therein and into pail 30 ~upported on shelf 31 of the cart 20 A ~econd or holding tank 44 is provided in the lower portion of the washing unit 10 ad~acent to the working tanX 33 to hold cleaning ~olution while the working tank 33 i~ being cleaned or otherwise ~ervicsd Th~ low-density material~ 45, ~uch as oil and grea~, which ~loat to the ~ur~ace o~ th~ cleani,ng ~olution are ~kimmed there~rom into a trough 46 disposed along one side of working tank 33 A
discharge line 47 and valve 48 are provided in the wall of the cabinet 11 on which trough 46 is di~po~ed to di~charge the low-den~ity materials 45 therein Both 601ids and liguids may be ~kimmed FIG 5 illustrate a pumping slement 50 and as~ociated piping arrangsment which ~8 u-ed to transfer clsaning fluid from the working tank 33 to the cpray ~anifolds 15, 16, an~ 17, from the worXing tank 33 to the holding tank 44, and from the holding tank 44 back to the working tank 33 Cleaning solution i~ ~upplisa to wa~her 10 through a line 41 ~rom a ~ourcs thereo~ which iB not ~hown in the drawings Th- pump 45 dir~ct6 the cl-aning colution ~rom ~nlst lins 51 to th~ ~pray h-aders lS, 16, and 17 through pump diwharg- llne 52, valv~ 53, and line 54 to th-reby dir~ct clsaning ~olution to automotlve part~ or othar ob~ects di-posed ~9 ~
in the wa6hing chamber 14. The ~pent cleaning ~olution drains down inclined ~urface 32 lnto the working tank 33. Valves 53 and 55 are both held open during the washing cycle ~o the cleaning ~olution can be continuously recycled from the work tanX 33 through line 56 back to the spray header~ lS, 16, and 17.
At 6uch time as when it becomes necessary or desirable to clean up or otherwise ~ervice the cleaning 601ution, the pump 50 i6 turned off and the cleaning ~olution in the working tank 33 is allowed to ~tand in a quiescent condition 60 the low-density materials 45 may float to the top thereof and the h~gher-density particulate matter 36 may settle to the bottom of the working tank 33. The low-den~ity materials 45 which ri~e to the top of the cleaning 601ution are skimmed into the trough 46 and di6charged from the washer through line 47 and valve 48. The container 34 in working tank 33 which capture~ the high-density particulate 36 i~ removed rom the working tank 33 ~o the ~ludge and other particulate 36 can be discharged there~rom. The time for removing the container 34 is not critical.
The cleaning solution in working tank 33 is withdrawn there rom through line 56 and valve 55 by pump 50 and directed to the holding tank 44 through lines S2 and 57, valve 58 and line 59. Valve 53 on line S4 i~ clo6ed off when pumping fluid to holding tank 44 to prevent cleaning fluid from being directed to the 6pray headers 15, 16, and 17. After the working tank 33 has been cleaned or 6erviced, the cleaning 601ution i6 withdrawn from the holding tank 44 through l~ne 60, valve 61, and conduit 51 to the pump 50 which directs the ~olution to the working tank 33 by ~praying the clean~ng ~olution onto the article~ placea within the wa~hing chamber 14 which then drain~ back to the working tank 33. If de~ired, a separate line with a u1tabl- ~alv- l-m-nt may b- provid-d to pump cl-aning , ~28~
fluid withdrawn from the holding tank 35 directly to the working tank 30 Valves 62 and 63 are provided in the lower portion~ of working tank 33 and holding tank 44, re~pectively, to further fac~itate cleaning of S ~uch tank6 It i8 contemplated, however, that the valves 62 and 63 will 6eldom be used After 6ervicing the wor~ tank 33, the 61udge container 34 may be lowered into the working tank 33 by pulley 41 and crank 42 and then the wa~her 10 iB ready for a further washing cycle As shown ~ore clearly in FIG 3, the vertical rising spray headers 16 and 17 are provided with pivotal arms 70 and 71 which facilitate washing automotive partC of widely varying izes in the washing unit 10 For example, should a tran~mission housing 72 be placea in the washing chamber 14, as ~hown in phantom, the arm~ 70 and 71 would be pushed upwardly BO
that the tran~mi~sion hou~ing 72 wouId fit thereunder If however, the wheeled ~upport tray 23 iB filled with 6maller automotive parts, such a~ alternator or starter hou6ing6, the spray arm~ 70 and 71 would be pivoted downwardly to a more horizontal position as 6hown in phantom BO that the cleaning ~olution can be directed more clo~ely to th- part~ to b- cleaned The horizontal manifold 15, which i6 disposed underneath the 6upport frame 12, has one or more nozzles which are aligned to impinge upon elements of the support frame 12 with ufficient horizontal force to rotate the frame 12 about the spindle 14 BO that the cleaning solution can be 6psayed evenly onto the part6 dispo6ed in the wheeled tray or baskQt 23 To load and unload the wa6her 10, the vertically r$sing door 18 i- lifted upwardly to an open po6ition and the cart or trolley 20 i- po~itioned in front o~ the opening thereo~ with the rall~ 21 and 22 thereon in proper alignment with rail~ 24 and 25 on the upper ~urface o~ the ùppost table 12 in order to ~ove --ll--the wheeled tray or basket 23 $nto and out of t~e washing chamber 14. AB shown more clearly ~n FIGS. 2, 3, and 4, the rails 21 and 22 are pr~vided with male guiding elements 81 and 82 which are ad~pted to fit S ~nto the matching recesses 83 and 84 provided in the front ends of rails 23 and 24 to ensure proper alignment of the rails and thereby enable the easy movement of the mobile basket 23 between the washing chamber 14 and the cart or trolley 20.
Although the invention i~ described herein primarily ln terms of conveying automotive parts to and from a washing apparatus, it 6hould be recognized that other type~ of articles may be conveyed in such a ~y~tem. Additionally, the article support frame is described herein as rotating in a horizontal plane by the lmp$ngement thereon of cleaning fluid from the ~pray header, although $t ~hould be recogn~zed that the support frame may be f~xed and the underlying spray header may rotate. Other, modifications and improvements can be made to the present invention without departing from the scope thereof.

locat$on~ from the standpoint of transporting dirty parts from a work station to the washer and then returning the cleaned parts back to the wor~ station or to a storage area.
With most of the prior art parts washing systems, the part~ to be cleaned were either hand carried to the washer or placed in a carrier and tran~ported to the washer in the carrier. In both cases, however, the parts would have to be hand loaded into the wa~her for cleaning which ls labor lntensive and time consuming.
What has been needed and heretofore unavailable is an effective parts conveying 6ystem integral with the washer which minimizes the time and effort reguired to clean automotive part~ and the like. The present invention satisfies this need.

An access door 18 i8 provided in cabinet 11 to allow for the loading and unloading of the washer 10.
The conveyor system embodying features of tbe invention includes a mobile carrier or trolley 20 having secured to the upper surface thereof parallel track or guide means 21 and 22 which are adapted to receive a wheeled article support tray or ba~ket 23.
Matching track or guide ~eans 24 and 25 are secured to lS the upper ~urface o~ support frame or turntable 12 disposed with~n the washing chamber 14 and are adapted to receive the wheeled article ~upport tray or ba~ket 23 from the trolley 20.
The trolley 20 i~ pu~hed by means o~ handle 26 to a distant location, ~uch a~ a work station at an automotive repair ~hop, and one or more parts to be cleaned are placed ~n the wheeled tray or ba~ket 23, which iB detachably fixed onto the trolley ZO by a latching ~eans (not ~hown), and then the trolley 20 is pushed to the washer 10 and positioned in front of open door 18 with the track or guide ~eans 21 and 22 al~gned with the track or guide means 24 and 25 securely mounted on the turntable 12. In this manner, the parts to be cleaned can be loaded lnto the wa6hing chamber 14 by pu~hing the wheeled tray 23 containing the dirty parts from the trolley or carrier Z0 onto the turntable 12 in the wa~hing chsmber 14. The trolley 20 is pulled b~ck ~n the acce~ door 18 in the front o~ cabinet 11 can be pulled down to a closea position and the washing cycle can be then ~tarted. To unload the cleaned part~
from the wa~her 10, the door 18 i~ lifted upwardly to an open po~ition and the wheeled tray 23 ls pulled out o~ ch~mber ~4 onto the trolley 20. A lat-h~ng ~ean6 (not 6hown) i8 engaged B0 that the wheeled tray 23 w~l not ~ove on tracks 21 and 22 wh~e the trolley 20 i8 being moved. With the tray 23 ~ixed, the clean parts may then be transported back to the work station or, if de~ired, to ~ storage area where the clean parts may be removed from the wheeled tray 23.
As shown more clearly in ~IG. 2, cart or trolley 20 is provided with a drain pan 27 for capturing fluid and other material which may drain or fall from the ob~ects placed in the wheeled tray or basXet 23 ~nd directlng the material through opening 28 into ~ collecting conta~ner or pail 30 dlsposed on A
lower shelf 31 Or cart 20.
The cleaning solution ~prayed on the articles in th~ washing cha~er 14 drain~ down inclined surface 32 into a worXing tank 33 di~po~ed ln the lower portion o~ the cabinet 11 beneath the support ~rame 12.
A particulate capturing container 34 is provided within the worklng tank 33 having one or more openings or a screen 35 in the wall~ thereof ~o that the cleaning solution may pass through ~uch walls when the container 34 i5 li~ted ~rom the wor~ing t~nk 33, yet the 601id partlculate mater~al 36 wh~ch 6epar~tes fro~
thQ clQaning solutlon i~ ret~ned ther~n. Th~
turntable 12 must be lifted from gp~ndle 13 ~nd e~ther removed from the chamber or leaned against ~ ~ar wall thereof 60 that the container 34 can be lifted through opening 37, removed ~rom the wa~her 10, and the sludge 36 and other particulate therein di carded. As in~i¢at-d ~n PIG8. 2, 3 and 6, a handle 38 i~
preferably provided on the container 34 ~o that it may be lifted by mQan~ o~ a hook 39 on a cable 40 wound on a pulley 41 operated by crank 42. When the container 34 i6 lifted by the hook 39 out o~ the working tank 33, , . . .

the cart or trolley 20 may be pu~hed forwardly eo that the leading edges o~ ra~ls 21 ~nd 22 are under the contalner 34 Container 34 can then be lowered onto the rail~ 21 and 22 and then be manually pulled ~urther S bacX onto ths ra~ls If desired, wheel~ can be provided on container 34 to facilitate movement on the rails 21 and 22 When properly positioned on the rail~
21 and 22, the ~lidable bottom 43 of the container 34 mAy be pulled open 80 that the 601ids 36 and other material therein will drop into the drain pan 27, through discharge opening 28 therein and into pail 30 ~upported on shelf 31 of the cart 20 A ~econd or holding tank 44 is provided in the lower portion of the washing unit 10 ad~acent to the working tanX 33 to hold cleaning ~olution while the working tank 33 i~ being cleaned or otherwise ~ervicsd Th~ low-density material~ 45, ~uch as oil and grea~, which ~loat to the ~ur~ace o~ th~ cleani,ng ~olution are ~kimmed there~rom into a trough 46 disposed along one side of working tank 33 A
discharge line 47 and valve 48 are provided in the wall of the cabinet 11 on which trough 46 is di~po~ed to di~charge the low-den~ity materials 45 therein Both 601ids and liguids may be ~kimmed FIG 5 illustrate a pumping slement 50 and as~ociated piping arrangsment which ~8 u-ed to transfer clsaning fluid from the working tank 33 to the cpray ~anifolds 15, 16, an~ 17, from the worXing tank 33 to the holding tank 44, and from the holding tank 44 back to the working tank 33 Cleaning solution i~ ~upplisa to wa~her 10 through a line 41 ~rom a ~ourcs thereo~ which iB not ~hown in the drawings Th- pump 45 dir~ct6 the cl-aning colution ~rom ~nlst lins 51 to th~ ~pray h-aders lS, 16, and 17 through pump diwharg- llne 52, valv~ 53, and line 54 to th-reby dir~ct clsaning ~olution to automotlve part~ or othar ob~ects di-posed ~9 ~
in the wa6hing chamber 14. The ~pent cleaning ~olution drains down inclined ~urface 32 lnto the working tank 33. Valves 53 and 55 are both held open during the washing cycle ~o the cleaning ~olution can be continuously recycled from the work tanX 33 through line 56 back to the spray header~ lS, 16, and 17.
At 6uch time as when it becomes necessary or desirable to clean up or otherwise ~ervice the cleaning 601ution, the pump 50 i6 turned off and the cleaning ~olution in the working tank 33 is allowed to ~tand in a quiescent condition 60 the low-density materials 45 may float to the top thereof and the h~gher-density particulate matter 36 may settle to the bottom of the working tank 33. The low-den~ity materials 45 which ri~e to the top of the cleaning 601ution are skimmed into the trough 46 and di6charged from the washer through line 47 and valve 48. The container 34 in working tank 33 which capture~ the high-density particulate 36 i~ removed rom the working tank 33 ~o the ~ludge and other particulate 36 can be discharged there~rom. The time for removing the container 34 is not critical.
The cleaning solution in working tank 33 is withdrawn there rom through line 56 and valve 55 by pump 50 and directed to the holding tank 44 through lines S2 and 57, valve 58 and line 59. Valve 53 on line S4 i~ clo6ed off when pumping fluid to holding tank 44 to prevent cleaning fluid from being directed to the 6pray headers 15, 16, and 17. After the working tank 33 has been cleaned or 6erviced, the cleaning 601ution i6 withdrawn from the holding tank 44 through l~ne 60, valve 61, and conduit 51 to the pump 50 which directs the ~olution to the working tank 33 by ~praying the clean~ng ~olution onto the article~ placea within the wa~hing chamber 14 which then drain~ back to the working tank 33. If de~ired, a separate line with a u1tabl- ~alv- l-m-nt may b- provid-d to pump cl-aning , ~28~
fluid withdrawn from the holding tank 35 directly to the working tank 30 Valves 62 and 63 are provided in the lower portion~ of working tank 33 and holding tank 44, re~pectively, to further fac~itate cleaning of S ~uch tank6 It i8 contemplated, however, that the valves 62 and 63 will 6eldom be used After 6ervicing the wor~ tank 33, the 61udge container 34 may be lowered into the working tank 33 by pulley 41 and crank 42 and then the wa~her 10 iB ready for a further washing cycle As shown ~ore clearly in FIG 3, the vertical rising spray headers 16 and 17 are provided with pivotal arms 70 and 71 which facilitate washing automotive partC of widely varying izes in the washing unit 10 For example, should a tran~mission housing 72 be placea in the washing chamber 14, as ~hown in phantom, the arm~ 70 and 71 would be pushed upwardly BO
that the tran~mi~sion hou~ing 72 wouId fit thereunder If however, the wheeled ~upport tray 23 iB filled with 6maller automotive parts, such a~ alternator or starter hou6ing6, the spray arm~ 70 and 71 would be pivoted downwardly to a more horizontal position as 6hown in phantom BO that the cleaning ~olution can be directed more clo~ely to th- part~ to b- cleaned The horizontal manifold 15, which i6 disposed underneath the 6upport frame 12, has one or more nozzles which are aligned to impinge upon elements of the support frame 12 with ufficient horizontal force to rotate the frame 12 about the spindle 14 BO that the cleaning solution can be 6psayed evenly onto the part6 dispo6ed in the wheeled tray or baskQt 23 To load and unload the wa6her 10, the vertically r$sing door 18 i- lifted upwardly to an open po6ition and the cart or trolley 20 i- po~itioned in front o~ the opening thereo~ with the rall~ 21 and 22 thereon in proper alignment with rail~ 24 and 25 on the upper ~urface o~ the ùppost table 12 in order to ~ove --ll--the wheeled tray or basket 23 $nto and out of t~e washing chamber 14. AB shown more clearly ~n FIGS. 2, 3, and 4, the rails 21 and 22 are pr~vided with male guiding elements 81 and 82 which are ad~pted to fit S ~nto the matching recesses 83 and 84 provided in the front ends of rails 23 and 24 to ensure proper alignment of the rails and thereby enable the easy movement of the mobile basket 23 between the washing chamber 14 and the cart or trolley 20.
Although the invention i~ described herein primarily ln terms of conveying automotive parts to and from a washing apparatus, it 6hould be recognized that other type~ of articles may be conveyed in such a ~y~tem. Additionally, the article support frame is described herein as rotating in a horizontal plane by the lmp$ngement thereon of cleaning fluid from the ~pray header, although $t ~hould be recogn~zed that the support frame may be f~xed and the underlying spray header may rotate. Other, modifications and improvements can be made to the present invention without departing from the scope thereof.
