iight?? BIEUMTC CLEANING AEPARATUS.
Application filed November 14,1924. Serial No. 749,987..
rThis invention relates to that class of pneumatic cleaning a paratus shown in my application 568830 led J une 1G, 1922, though obviously it could be used for other purposes.
The principal object oi the presentinvention is to improve what 1 denominate the induction chamber or" the device, whereby the lluid under pressure exerts maximum eliect in drawing in the air through the cleaning nozzle.
Another feature of the invention is t-he improved means provided for adjusting the nozzle in the induction chamber to get the maximum benefit of the iiuid under pressure while the cleaning apparatus is in operation.
.another feature of the invention resides in the provision of means'tor a stream line motion in the fluid under pressure at the end of the nozzle of the cleaning pipe.
Other features of the invention relate to the ease of adjustment oi the nozzle in theV induction chamber and the centering of the same as it is moved iny and out.
With these and other object-s in view which will be apparent as the description proceeds, l will now describe my invention in conne@ tion with .the accompanying drawings in which:
Fig'. 1 is a view 4showing the device as ap` plied to a pneumatic cleaner, the device being in side elevation.
F ig. 2 is a vertical median section showing the construction ot the device with the Venturi-tube closed.
F ig. 3 is a view similar to Fig. 2 with the Venturietube opened.
F ig. a is a side elevation of the sliding jet tube.
Fig. 5 is a section on the line 5,-5 of Fig. 2.
4ig. 6 is a section on the line 66 of Fig. 2
Fig. 7 is a section showing the construction ot the suction nozzle with its reverse curves. The apparatus comprises a tube 1 which may be connected to a suction nozzle as, for instance, the one shown in ,the atoremen tioned application, This tub-e 1 terminates just outside of my induction chamber and there is attached to it in any convenient lmanner at 2, a nozzle 3. |This nozzle is preferably ot a uniform exterior diameter through most of its length and cone-shaped at its end as shown in Figs. 2 and 3.
lli/ry induction chamber comprises an outer shell 4i with an inlet 5 thereto on the end of which may be attached a pipe connected with the pump or compressed air supply such as is .also illustrated in my aforementioned application.
The interior of the shell lli provide with ribs 6, so shaped passes through the compressed air pipe 5, keep the currents of compressed air from ruiming together at the top and causing eddies, lthe ribs 6 being shaped on stream lin-es as shown best in Figure 5 and directs the compressed fluid to flow through the right-hand side of' the shell, Figs. 3 and il, at all points around the end of nozzle 3, in an unbroken stream thereby eliminating eddy currents and greatly increasing the efficiency of the apparatus. Those ribs also serve the function of' centeringthe nozzle 3 and guiding it in and out of the shell as shown in Fig. 5. 0n one side of the shell 4l there is preferably formed a flange 7 and a packingv chamber 8 to hold a packing to prevent leakage between the nozzle 3 and the shell or chamber d.
Attached to the flange 7 as byscrews 9 is a ll preferably screw-threaded sleeve 10, which may be 'exthat as the air i tended into' the packing box 8` to preserve y the right pressure on the packing therein.
Embracing the threaded portion of the sleeve 10 is a second sleeve12 screw-threaded to co-act with the sleeve 10 at one end and at the yother end provided with an encircling iianged ring 14. .The nozzle 3 may conven iently be provided with a flange 1,5 having notches therein, not shown, through which projections on the inner periphery of ring 14 may pass as in an ordinary bayonet jointconstruction, in assembling the ring 1li-back of the flange 15 iitting between tl e ring 1% and a flange 16 on the'sleeve 12. Holes 18 may be convenientlv'dri-lled through the embracing portions of the sleeves 12 and 14: which serve as sockets for the insertion ot a pin to screw up or unscrew the sleeve 12 on the sleeve 10.
It will be apparent that as the sleeve 12 and ring 11i move in or out it will carry with it'the nozzle 3 to coact near its end with a bushing 19 shown in detail in Fig. 'Z' and the relative positions ot the end of nozzle 3 and the interior of the bushing 19 are shown in Figs. 2 and 3. The interior surface of this bushing 19 it will be seen is on reversed curved lines at its end adjacent the end or' the nozzle 3 which guides the inrushing fluid on stream lines up to the nozzle 3 and due toits shape, it admit-s a large quantity of the fluid under y of my invention pressure up to this point to get the maximum benefit in drawing fluid through the nozzle 3.
By reversing the motion of the sleeve l2 and ring 14, the nozzle 3 can be moved to the position shown in Fig. 3 and it is apparent that the nozzle 3 may be adjusted at just tiet position where it co-acts with the interior surface of the bushing 19 to get the best effect from the compressed air rushing through the induction chamber. The ribs 6 also act to deliver the inrushing air in the proper direction to get the maximum effect with the power employed.
On the opposite side Vof the induction chamber from the sleeves lO and l2, I may attach a flaring nozzle 21 similar to the nozzle shown in my aforementioned application which may lead the dust-laden fluid to thedust chamberl 22 similar to the one shown in said aforementioned application.
lt is apparent that various modifications may be made without departing from the spirit thereof and l do not wish to be limited to the exact construction shown except as lherein indicated in the following claims.
