EDWARD A.. ROLE, OF LUN@ BEACH, CALIFORNIA.

CONVEYER.

Application led June 2,

To ZZ 11i/tom it may concern.:

Be it known that l, EDWARD A. BOLE, a citizen of the United States, residing` at Long Beach, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Conveyors, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention relates generally to conveyers, and aims to provide a novel and improved conveyer structure, adapted especially for draining sewage and removing the solid matter therefrom to be burned in an incinerator or otherwise disposed of.

Another object is the provision of such a conveyer comprising an endless conveyer member of novel construction having hinged screens to facilitate the cleaning thereof.

A further object is the provision of means for discharging air, steam, water or other fluid through the screens fpr cleaning them in a practical and effective manner.

A still further object is to improve the receiving end portion of the conveyer which is in the sump, whereby the sewage is properly delivered on the conveyer member, and whereby the receiving end portion of the conveyer structure can be raised for making repairs or adjustments.

Vith the foregoing and other objects in view, which will be apparent as the descrip tion proceeds, the invention resides in the construction and arrangement of parts as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of the improved conveyer, portions being broken away and shown in section.

Fig. 2 is a fragmentary end view looking in the direction of the arrow 2 in Fig. 1, on an enlarged scale,

Fig. 3 is a horizontal section on the line :3 3 of Fig. 2.

Fig. l is a plan view of the receiving end portion of the conveyer, on an enlarged scale.

Fig. 5 is a section on the line 5-5 of Fig. il. on an enlarged scale.

Figs. 6 and 7 are cross sections on the re- 1924. serial No. 717,336.

spective lines 6-6 and 7-7 of Fig. 1, on an enlarged scale.

The conveyer is inclined, with its lower end portion within a sump 14 through which the sewage flows from the inlet 15 to the outlet 1G, and the sump has a depression or cavity 17 between the inlet and outlet in which the lower end of the conveyer is disposed.

The conveyer structure includes a suitable frame 18, which is inclined, and which is supported by posts or

standards

19 and 20. rihe frame has a loose receiving end section or portion 21, which is hingedly connected to the lower end of the main frame 18, so that the section 21 can be swung upwardly and downwardly out of and into the depression 17.

The endless conveyer member which is mounted for circuitous movement on the inclined frame, comprises the endless sprocket chains 23 at the opposite side edges, composed of links or bars hingedly connected together. Between the sprocket chains are the screens 2e of suitable mesh, which have frames 24, and the side members of the frames have outturned flanges 25 which are pivotally connected, as at 26, with the pivots of the links of the chains 23, the frames 24 of the screen is trailing from the pivots or hinges 26. The screen frames overlap at the upper run of the conveyer member, the rear free edge portion of each screen frame overlapping the hinged edge portion of the next screen frame in rear, whereby the solid matn ter will be carried upwardly by the screens.

The flanges 25 assist in preventing the inatter on the screens from running over the side edges of the screen frames, said flanges projecting upwardly along the upper run of the conveyerl member.

The main frame 1S and section 21 have rollers 27 for guiding the sprocket chains 28 at their upper and lower runs, and

polygonal sprocket wheels

28 and 29 are provided at the upper and lower limits of travel of the conveyer member, over which the sprocket chains pass.

As shown, there are two companion con- 'feyers disposed side by side, in order that either one can be used or both of them simultan-eously. Also, one conveyer can be idle, for purpose of repairs, cleaning or adjustments, while the other is in operation, and

ll (l the two conveyors can be alternated, to provide Jfor continuous operation.

The traine y18 of each conveyor basin elined rails 30', preferably of wood, below the lower run of the conveyer member, on which the rear ends ot the anges can drag as the screen frames are moved downwardly into the sump.

rlhe sprocket wheels 28 of each conveyer are mounted for rotation on a shaft 30. 'supported by the standards 20, the shafts 30 of the two convevers being' in alinement, as seen in Fig. 3. rihe shaft 30, for reasons which will appear hereinafter, is stationary, and the sprocket wheels 28 rotate on said shaft. In order to drive the conveyer member, sprocket wheels 3l are secured to the sprocket wheels 28 and sprocket chains 32 pass around the sprocket wheels 3l and spr cket wheels 33 secured on a drive shaft 34 liournaled -for rotation on the standards 2@ above the corresponding sprocket wheels 28. The shaft 34 has a pulley wheel 35 to receive a belt driven b v an 'engine or motor.

in order to clean the. screens 24, air, ste-ani, water or other Vfluid is delivered into each shaft 30 under pressure, said shaft being hollow or tubular, and a discharge nozzle 3G projects from the pipe and has a perforated T-head 37 directed douuiwardly toward the upper ends ot the rails 30. lhe fluid discharged from the sp ay head 37 will pass from within the conveyor member outwardly through the screens, as the screens movl around the sprocket wheels 28, thereby cleaning the foreign matter from the screens, and the pressure oic the lIluid against the inner sides of the screens will also throw the screens away trom. the sprocket chains against the upper terminals of the rails 30', so that the sudden stopping vof the screens by their contact with the rails 30 will assist in jarring or shocking loose the matter which may cling to the screens. This, in

addition to the discharge 'olf theliuid underpressure through the screens, will effectively clean the screens as they start dowi'iwardly.

les shown in Fig. 2, air under pressure is supplied into the shafts y3() by blowers 38 having the discharge pipes 39` connected to the outer ends of the shafts 30,

in order to dissolve oil, grease and similar substances, from the screens a solvent therefor can be supplied to the air?, so as to be discharged through the screens. Thus,

:Feeders 40 of any well known hind can be attached to the air delivery pipes Si) tor 'feeding the solvent or solution to the air. Such feeders can be similar to those used lor suiplying chemicals or boiler compounds t-o water supplied to stean'i boilers, or the like, as well, known.

The lower sprocket Vwheels 29 of each conveyor are secured upon a shaft 4l that is joianaled for rotation t its ends in bearings or slides 42 that are mounted for upward and downward sliding movement in the standards or

posts

43 and 44 mounted in the sump 14. Said standards are channeled to receive the slides, and the intermed' ate standard 44 may be an beam to accommodate the adjacent slides 42 oll the two conveyers while the standards 43 are composed of channel irons. rlhe slides 42 can thus move along the standards when the 'frame section 21 is swung upwardly and downwardly, and the section 2l has longitudinal slots 45 engaging the hinge pins 22, so as to permit of a sliding movement of the section relatively to the main frame 1S when the section 2l is swung upwardly and downwardly, on account ot the shaft 4l and slides 42 having a straight line motion along the standards 43 a-nd 44.

A windlass is provided for raising the section 21 of each conveyer structure. Thus, a shaft- 46 is journaled on the upper ends of the

corresponding standards

43 and 44, and has drums or spools 47 on which chains or other flexible elements 48 are wouiiid, the lower ends oi said chains bein o' connected to the corresponding' slides 42. lhe shaft 4G has a cranli: 49 at its outer end or other means for rotating the shalft to wind the chains on the drums, so as to raise the section 21, as seen in dotted lines in Fig. 4, thereby permitting repairs or adjustments to be made without emptying the sump or taking down the conveyor structure. A ratchet device 5() is provided tor preventing` reverse rotation of the shait 4G until it is desired to again lower the 'traine section 2l.

In order to direct the sewage to the upper run of: the convcyei.' member, vertical side plates 5l are provided above the section 21 of each conveyor structure, and said plates 5l are supported by suitable supports 52 secured to the section 21, with the lower edges o'l the plates 5l disposed between the chains 23 and tlaiiges of the screen tra-nies 24. Strips are secured to the iiuicr sides ol the plates 5l above (be screen frames, and said strips have olliset aprons Awhich depend and oiferlap the inner sides of the flanges as seen in Fig. G, thereby directing the sewage to the screens 24, the aprons 54 preventing the sewage from passing 'the side edges of the screen frames and also keeping the solid matter on the screens until raised out of the water. rl`he sump 14 is provided with an abutment therein, and said abutment extends to the standard 44, and also forms 'the channels 5S leading Yfrom the inlet l5 to the two conveyers. The plates 5l project beyond the lower end o'lf the conveyor and overlap the sides oit the channels 58, as seen in Fig. 4, so that the sewage ilows lroin the channels 58 between the plates l to the conveyor members.

fi, plate 5G is disposed between each pair of side plates 51 and is curved or arched over the sprocket wheels 29, the side edges of the plate 5G being secured to the strips 53. The projecting edge portion of the plate 56 is adapted to overlap and bear on the bottom of the sump 111 between the inlet 15 and depression 17, in order to prevent the sewage from passing under the lower end of the conveyer. In other words, the plate 56 detlects the sewage over such plate onto the upper run of the conveyer member, so that the sewage is strained, the water passing on through the screens, while the solid matter is carried upwardly with the screens on the upper run of the conveyer member'.

t suitable gate 57 can be provided for each channel 58, in order that either channel can be closed, so that the sewage will pass through the other channel only. In this way, one conveyer an be in operation, While the other one is being repaired, cleaned or overhauled.

In opera-tion, the sewage flows from the inlet 15 through the channel 58 between the plate 5l and over the plate 5G to the lower portion of the upper run of the conveyer member, the water passing through the screens 24;', and said screens arrest the solid matter which is carried upwardly with the upper run of the conveyer member. The screens 24, as they pass around the sprocket `wheels 28, are swung outwardly and downwardly away from the sprocket wheels 28 and chains 28, against the rails 30', and the fluid being discharged through the screens will assist in swinging the screens outward ly and will also dislodge the foreign matter and blow same from the screens. The fluid thus has a double function, namely, to swing the screens outwardly and downwardly so as to strike the rails 30 with a sudden jar to loosen the foreign matter, and, secondly, to discharge outwardly through the screens for loosening and removing the foreign matter therefrom. The screen trames 2=1 ldrag on the rails 30 in moving downwardly into 'the sump, and the screen frames move upwardly around the sprocket wheels 29 under the plate 56 and will operlap in moving upwardly from under the plate. 5G so as to catch and elevate the solid matter of the sewage. lVhen the gate 57 of one conveyer is closed, the section 21 can be raised, as seen in dott-ed lines in Fig. 4, for purpose of cleaning the device or making repairs or adjustments. The matter discharged from the upper end of the conveyer can be burned in an incinerator or otherwise disposed of.

Instead of using the tubular shaft 30 for supplying the Huid, it is possible to extend a pipe upwardly between the upper and lower runs of the conveyer member adjacent to or across the shaft 30 to the spray head 37. In other words, the nozzle 36 can illustrate the end of a pipe extending between the sprocket wheels 28.
