The..frame includes :an upstanding telescopic elevators orguide standard formed by anouter vertical support 14 rigidly attached .to the base member 1 andan-inner vertical. support 15 mounted for movement vertically. withrespect to theouter support 14. The outer support is formed by a pair of verticalchannel guide members .16, and 17 welded at their: lower ends to the base member 1'at thesidesthereof and connected at their upper endsto a; topcross. bar 18 Which-joins the :upper ends of the chan- vz nel members 16 and 17. A-horizontal shelf 19 is -supported on the outer support .14 .and projects. rearwardly therefrom. The inner support .15 includes a pair of vertical channels 20 and 21 mounted for travel vertically with respect to the channel members 16 and 17 and also includes a top cross member 22 joining the-top ends of'the'channels 20 and 21. These channels carry two vertically spaced pairs of laterally. alined rotatably mounted rollers'23 and "24 which engage the inwardly porjecting=flalnges -'of*the-channel members 16 and '"17 and are guided vertically thereby.
A" load-supporting carriage 25 is mounted for "travel vertically' 'on the inner support"-15' of the upstanding 3 elevator standard and is provided at its forward end with a pair of alined, laterally spaced cantilever arms 26 and 27 and at its rearward end with a flat vertically disposed plate 28 positioned between the channels. The flat plate 28 has rearwardly projecting flanges 29 that support two vertically spaced pairs of alined, laterally spaced rollers 30 and 31 that are guided between and engage the flanges projecting from the channels and 21. A reinforcing arm 32 extends between a bottom side edge of the plate 28 and the forward end of each of the arms 26 and 27 to provide a'strong triangular support.
The carriage is raised and lowered by means of an hydraulic cylinder 33 mounted in vertical position upon the base member 1 midway between the side posts formed by channel members 16 and 17 of the guide standard. The cylinder 33 has a vertically movable piston rod or plunger 34 that carries a pair of laterally spaced sprocket wheels 35 at its upper end. A sprocket chain 36, attached at one end to the plate 28 of the carriage 25, extends over each sprocket wheel 35 and is attached at its opposite end to the truck frame. The upper end of the plunger 34 engages the top cross member 22 of the inner support 15 to move the same vertically with the plunger. By the use of the sprocket and chain hoisting connection, the inner support 15 moves half as far as the carriage 25 during each revolution of the sprocket wheels 35. The vertically spaced pairs of rollers 23, 24, 3t and 31 and the supports 14 and 15 of the elevator standard provide a strong support for the load supported on the carriage 25 at all vertical positions of the carriage and the inner support 15. The inner support 15 is particularly advantageous where a heavy load is to be lifted a considerable distance, since it allows the use of a relatively short standard.
Immediately to the rear of the elevator standard the rear portion 2 of the base member 1 supports a battery frame 37 containing an electric battery 38 which is connected to the electric motor within housing 9 by an electrical conduit 39.
A rigid metal annulus 49 is mounted on the forward portion of the carriage 25 for rotation about a horizontal axis by alined horizontal trunnions 41 that are journaled in upwardly extending flanges d2 welded to the top of the forwardly projecting arms 26 and 27, the trunnion axis being located a short distance in front of the center of the annulus 4i} as viewed in Fig. l. A lever arm 43 is welded to the annulus 4'1) at its one end and is pivotally connected to a piston rod 44 of a single-actingreciproeating tilt motor 45 at its other end. The cylinder of the tilt motor 45 is pivotally mounted on an upstanding flange 46 welded to the arm 27 at the inner end thereof. I
A short flexible conduit 47 is connected at one end to the intake of the motor 4-5 to supply motive fluid thereto while accommodating tilting movement of the motor 45 with respect to the carriage 25.
strokes of the tilt motor 45 and the lever arm 4-3 are of such lengths that the annulus 46 may be tilted approximately 135 from the position shown in Figs. 1 and 2 to the pouring position shown in Fig. 3.
The metal annulus 40 is preferably of cylindrical form and includes upper and lower tubular metal stiffening rings 49 and 5t welded to the top and bottom edges thereof. An inflatable tubular rubber ring 51 is located closely adjacent the inner surface of the metal annulus 4t) and between the rings 4% and. 5b. The tubular rubber ring 51 is normally axially elongated in cross sectional form and contains a similarly elongated annular air chamber therein whereby the inner diameter of the ring will be radially contracted when the ring is inflated as shown in Fig. 9. To prolong the life of the ring without greatly increasing the cost thereof, it is preferable to provide fabric reinforcement at least on the inner barrelgripping surface of the rubber ring. As herein shown the ring 51 has a substantially cyiindrical fabric rein- The other end of con duit 47 is rigidly connected to the carriage 25 at 48. The
. slots 53, and along the inner surface of the annulus 40.
The two ends of each strap 54 are connected together by suitable fasteners 55. A short flexible conduit 56 is rigidly connected at one end to the metal annulus 40 and at the other end to a rigid pipe 57 fixed to the top of plate 28. The conduit 56 accommodates tilting movement of the annulus 46 with respect to the carriage 25 while conveying air to inflate and deflate the ring 51.
The horizontal shelf 19, which is supported on the guide standard of the truck frame, provides a support for an air compressor 58 that is driven by an electric motor 59 and for a pair of housings 6i and 61 and their associated electric motors 62 and 63. The housing provides a reservoir for hydraulic fluid and contains a pump 64 driven by the motor 62 for supplying motive fluid to the tilt motor 45. A supply conduit 65 conveys hydraulic fiuid from the pump 64 through a two-way valve 66 to a conduit 67 which is rigidly connected at 68 to the guide standard of the truck frame near the plane of the shelf 19. Connected between the end 68 of conduit 67 and the end 48 of conduit 47 is a long flexible conduit 69 which conveys motive fluid to the tilt motor while permitting relative movement of the carriage 25 and the shelf 19. The valve 66 has a first position in which fluid is supplied from conduit 65 to conduit 67 and a second position as shown in Fig. 10 in which fluid is exhausted from conduit 67 through a bypass conduit 76.
The housing 61 is similar to the housing 60 in that its acts as a reservoir and contains means including a pump driven by the electric motor 63 for supplying hydraulic fluid under pressure to cylinder 35 to raise and lower the plunger 34. The hoisting system employed on the lift truck of the present invention may be of the type described in the aforesaid Patent No. 2,520,857.
The air compressor 58 supplies air under pressure through a supply conduit 71 and a two-way air valve 72 to a conduit 73 which is rigidly connected at 74 to the guide standard of the truck frame near the plane of the shelf 19. A long flexible conduit 75 is connected between the rigid conduit connections at 57 and 74 to convey air to and from the rubber ring 51 while permitting relative movement of the carriage 25 and the shelf 19. The two-way valve 72 has a first position wherein air under pressure is conveyed from supply conduit 71 to the flexible conduit 75 and a second position as shown in Fig. 10 wherein air is exhausted to atmosphere from the flexible conduit 75.
The long flexible conduits 69 and 75 are preferably of about the same length and have loop portions that pass beneath a pair of similar slack take-up rollers 76 and 77 which are supported in the loops of said conduits and which are provided with annular circumferential recesses that receive the flexible conduits. The rollers 76 and '77 are guided vertically by a pair of similar roller guide channel 78 and 79, the inwardly projecting flanges of which provide guiding surfaces which engage the rollers. Channels 16 and '78 and channels 17 and 79 are fixed to the frame member 1 and are spaced apart a distance only slightly greater than the width of the rollers 76 and 77, respectively, so as to provide a vertical guiding means of rectangular cross-sectional form in which the rollers may roll. The weight of the rollers 76 and77 biases the long flexible conduits 76 and 69 in the downward direction to take up the slack caused by movement of the carriage 25 with respect to the shelf 19 of the truck frame. t
H The lift truck described above is usually employed ayrsegses for-hoisting; moving and dumping-vats,-' hogsheads",-'- or large 'barrelsof the-typeshown= in-Figs. 1 to-' 3. Fig," 1 shows a'centrally bulged barrelorvat80 of'cir'cular" cross section containing'a large volume ofIiquid; the maximum diameter of the barrel at: the bulge thereofb'e ing slightly less than the normaldi'ameter of :theexpanded' inner surface 52 and largerthan thediameter-of'the'con tracted inner surface 52. Theannulus-40 andririg 51" may obviouslybe made of various sizes-to=handle'dif ferent types of vats and hogsheads.
The method of thepresent invention-comprises placing'the inflatable rubberring 51 above and coaxial -with the barrel 80 as shown in Fig. 1, sliding'the'ring'down' over the bulge of thebarrel to the'dotted line position shown inFig: 1, and radially; contracting the inner'bar rel-gripping surface of the ring-51and'raising the ring' so'that the internal surface 52 engages and grips substan= tially'the entire circumference ofthe barrel 80 below'its' bulge. The barrel may be raised -to"any desired 'height as shown in-Fig. 2 while'the uniform gripping "pressure is maintained throughout the circumference of the bar-' rel. According to the method of "the -present inventionthe ring 51 is tilted about a horizontal axis as shown in Fig. 3 to discharge the contents of thecbarrel80r Thereafter, the barrel may be tilted back to its'horizontal position and lowered to the ground; The internal surface of the 'ring 51'is expanded to its normal diameter'to .releasethe grip on. the barrel andtopermit sliding of the ringupwardly over the bulge of the barrel 80."
The preferred apparatus for performing themethod is the industrial lift truck described abovewhichzcarries the tiltable ring 51. 7 Before the barrel; 80is'lifted icar riage 25. is elevated and the rubber'ring 51is positioned above and coaxial with the'barrel "80; To. facilitate centering of .the barrel 80 with respectto 'therubber ring 51, it" is preferable to employ the positioning pmeans 6 of the side members 3 and 4. The barrel-engaging outer surfaces of the positioning stops 6'are located at predetermined equal distances from the vertical axis oflthe rubber ring 51 so as to locate the lift truck. in proper lifting position when they engage the barrel 80? The ring 51is slid down over the bulge of the barrel after the valve70 is placed in the exhaust position shown in Fig. 10 to deflate the ring. Valve 72"is then. moved to a position wherein conduit 71 is connectedto conduit '73." A relatively low predetermined initial pressure, for .ex-.- ample 10 to p. s. i. is supplied to the ring 51toinflate the'same as shown in Fig. 9, to reduce its internal.diam-. eter, and to supply suflicient air to the rubber'rin'g 51 to support the barrel, thereby providing a-uniforrn' gripping pressure throughout the entire circumference ofthe barrel. The carriage is then elevated to the desired height, and the barrel is transported horizontally byythe driving wheel 7 to the desired location.
The valve 66 may be placedin a position blocking made "without departing from the spirit ofthe invention;
flow to and from the tilt motor during hoisting and lateral moving of the barrel 80 to prevent undesirable tilting. However, the center of gravity of the barrel ispreferably located a short distance-behind the trunnion axis at 42'so that the piston may be held'in retracted position and the barrel held horizontal as shown in Fig. 2 by the weight of the barrel alone. After the barrel has been moved to the desired location, the valve 66 is moved toaposition connecting conduit to .conduit 67. Pump 64then supplies hydraulic fluid through the conduits.65, 67, 69 and 47 to the motor 45"so as to tiltthebarrel to a pouring position and discharge its liquidcontents. Theannulus 40 may be tilted about ffomQthe position shown in Fig. 2 to the position shown in Fig. 3 so as to provide a pouring angle of approximately 45. The barrel is tilted back to its original horizontal position by turning valve 66 to the exhaust position as shown in Fig. 10. The weight of the barrel causes the piston rod 44 to retract, and therefore the motor 45 need not be of the double-acting type. The barrel may be released What [claim-is:
