Application ledJune 11,

My invention relates to improvements in refuse collecting and delivering vehicles, particularly of the self-propelled class, as 1nstanced in prior Letters Patent issued to me' dumped from the scattered cans or containers into a low hung hopper, of which one is 'on each side of the vehicle, and from each hopper the refuse is carried upward and rearward by an endless conveyor, operatedby the vehicle driving mechanism, through a chute opening into a dumping body, also operated by the vehicle driving mechanism.

My present invention has for its objects Y among others, to improve the construction and operation of the conveyor, its enclosing chute, and the dumping body, and the Vmeans for operating the conveyor and-the dumping body from the vehicle drivingk mechanism, and to prevent the clogging of the conveyor in its chute. Y v

To this end my invention comprises flights of novel construction, alternated with the buckets on the conveyor chains; shields beneath and to therear of 4the' ascending buckets and flights to support 3o refuse in vthe buckets and Hights; drums around the conveyor sprocket wheels and fitting the chutes and hoppers to cooperate therewith in leading the refuse from the hoppers to the conveyors; a

and extension of the body between lthe veyor chutes to increase the capacity of the body; improved means for operating-and l controlling the operation of one or both conveyors from the vehicle driving mechanism; and improved means for operating and controlling the operation of thedumping body from the vehicle driving mechanism.

1n orderthat my invention may be fully understood, l shall irst described in detail the mode in which l at present prefer to carry the invention into practice and then particularly point out the various features of the invention in the claims.

Reference is to be had to the accompanying 5o drawings forming part of this application in which corresponding parts are designated by the same number in all the figures.

In the embodiment of my invention thus illustrated, 'i' designates' the frame of the vehicle mounted on wheels 8 and driven by a motor in the usual manner.

9 designates the usual shaft of the vehicle, shown in section in Figure 3 and indicated in dotted lines in Figure 4. 10 designates the transmission, which together with the chassis and vehicle driven mechanism here illustrated is that of the ordinary Mack truck. 11 designates the ordinary standard one-speed Mack power take-0E, operated through the shaft 12, from the transmission 10.

From the drive shaft 13 ofthe power take od 11 and thus from the vehicle drive shaft 9,1 prefer in this example of my invention to operate and controlfthe conveyors 14, 15 in their respective chutes 16, 17 as follows:

The conveyor chains 18, 19 at their lower longitudinal drive ends run around sprocket wheels 20, 21which are -fixed axially on aligned but independent transverse shafts 22, 23, which turn in Suitable bearings on the frame 7. s

The inner-ends of the shafts 22, 23, as best 3 and 4 are connected by flexible couplings 24, 25 with axially aligned short shafts 26, 27 mounted in ball- bearings 28, 29, in a casing` 3() iixed on .the frame. `The inner ends of the short shafts 26, 27 are borne and spaced yieldingly apartby a spring-pressed plunger bearing 31, worjiing in a socket in the end of theshaft 23,y and bearing` against the end of the shaft 27.

On inner annular bearings 32, 33, surrounding the shafts 26, 27 and in outer annular bearings 34, 35, mounted within the casing 30; l

'motor and drive shaft 9 of the vehicle.

In opposite ends of the Worm wheel hub 36 are formed female clutch sections 44, 45 (Fig ure 7) adapted to be engaged and disengaged simultaneously or alternately by correspond ing male clutch sections 46, 47, keyed so as to be compelled to turn with but to slide axially on the respective short shafts 26, 27. The

4male clutch sections 46, 47 are formed with annularly grooved clutch collars 48, 49, which are engaged loosely and can be shifted axially by corresponding segments 50, 51 of clutch plates 52, 53, mounted to slide in guides 54, 55 in the casing 30 parallel to the axis of the clutch shafts 26, 27. n

By properly shifting the clutch plates, 52, 53 in their guides, the main driving worm Wheel 37, can thus be clutched to either or both the conveyor operating shafts l26, y27, or unclutched from both said shafts so as to operate either or both conveyors 14, 15, simultaneously or neither of them.

To operate the clutch plates 52, 53, and thus the conveyors 14, 15 selectively as desired, I, in this example of my invention fix anti-friction cam-studs or followers 56, 57 on the clutch plates to ride in cam slots 58, 59, in a cam-plate `60, and the cam-plate 60 is mounted to slide transversely to the shafts 26, 27 in a guide 61 formed in the casing 30.

The cam slot 58 has a terminal part62 at an angle to the motion of the cam, a medial part 63 in line with said motion and a terminal part 64 at an angle, as shown in Figure 6.

The cam slot 59 has a terminal part 65, in line' with the motion, a medial part 66 at an angle, and a terminal part 67, parallel to but inside the opposite terminal part 65.

The cam-plate 60 is shown in Figure 5, operated by a link 68 and adjustable handle lever 69.

With this constructiomrwhen it is desired to render both conveyors 14, 15 inoperative the cam-plate 60 is moved to thegposition shown in Figure 6, thus disengaging both clutch sections 46, 47, from the driving worm wheel .37. f

To operate both conveyors 14, 15, simultaneously, the cam-plate 60 is moved to bring the cam- followers 56, 57, into the ends of the cam slots 64, 67, thus engaging both clutch sections 46, 47 with the worm wheel 37.

To operate the conveyor 14 but not the conveyor 15, the cam-plate is moved to bring the cam followers 56, 57 into the ends of the slots 58, 59, thus engaging the clutch section 46, but leaving the clutch section 47 disengaged. p

To operate theconveyor 15 but not the conveyor 14, the cam-plate 60 is moved to bring the cam follower 57 into the beginning of slot 67, and the cam follower 56 into the end of the slot A63, thus engaging the clutch section 47 but leaving the clutch-secti0n 46 disengaged.

The conveyors 14, 15 can thus be conventhe links 74, carrying the buckets 70, and I taper the flights 71 toward their outer ends so as to automatically release the refuse which may be caught betwen their tapering side edges and the sides of the conveyor chutes 16, 17, or the refuse receiving hoppers 75, 76, from which the chutes 16, 17 lead upward and rearward.

The buckets carry the softer or finer material, and the flights the harder or coarse'r material. y

0n upper transverse conveyor shafts 82, journaled in opposite sides of the frame` are mounted loose sprocket wheels 81, around which the respective conveyor chains, 18, 19, travel. On the conveyor shafts 22, 23 and 82, 82, are fixed, on opposite sides of the respective sprocket wheels 20, 21, 81, 81, drums 77, 78, having on their outer sides flanges 79, 80.

The inner ends of the buckets and flights are tapered to fit the peripheries and flanges of the respective pairs of drums, and the use in the hoppers and dump all the refuse,

as the buckets and flights pass over the upper sprocket wheels, into the dumping body 84, through the upper chute openings 8 3. .l L

To support the upwardly `passing links, flights 71 and buckets 70, and retain the refuse therein, I fix on each chute closelyvbeneath and to the rear of the same, an inclined shield 85 extending the distance between the lower and upper drums 77, 78, and across the chute, over which the inner ends of the flights travel and by means of which they are guided. Likewise to support the downwardly passing links, buckets and flights, I' fix on the rear of each chute 16, 17, a wear plate 86, extending from the chute opening 83 to the lower hopper andlacross the chute, over which wear plate the outer ends of the downwardly passing flights 71, travel, and by which they are guided.

The inner and outer edges of the flights 71 are formed with upturned transverse shoes 87, 88, the outer lips acting as shields to scoop and retain the refuse, and also as bearings on the wear plate 86, and the inner shoes-87 act as bearings on the shield 85.

The dumping bodyl 84, has segmental up-l To increase the capacity of the dumping v body 84, I form it with a forward constriction and extension 90 which fits and tilts between the chutes 16, 17.

T o tilt the dumping body 85 from the vehicle drive 'mechanism when desired to dump its contents, I arranged an ordinary screw hoist- 91 beneath the same as indicated in dotted lines in Figure 4, and operate the same from a secondary drive shaft 92 through an ordinary clutch (not shown)V from the power take up 11, driven by the vehicle motor.

It is evident that many changes may be made in the details of construction and arrangement herein described without departing from the boundaries of my invention which are deiined by the following claims.

It is evident also that an attractive toy vehicle ma be made on the general lines herein describe in which case the motor may if desired be omitted and the conveyors and dumping body operated by hand, as by cranks or hand Wheels on the conveyor shafts or on any of the operating shafts.

I claim as my invention:

1. A refuse vehicle provided with receiving hoppers on both sides, inclined conveyors4 on both sides leading upward from the respective hoppers, separate driving shafts for the driven thereby,`a double clutch section driven thereby, a separate clutch sections to drive each conveyor shaft, and means for engaging either of the conve or driving clutch sections with and disengagmg it from the double motor-driven clutch section.

2. A refuse vehicle in accord with claim 1 provided with means for engaging both of respective conveyors, a motor, and a ,shaft the conveyor clutch sections simultaneously f with or disengagin them both simultaneously from the dou le motor-driven clutch section.

a 3. A-refuse vehicle in accord with claim 1 in which the separate conveyor driving shafts are axially aligned and a yielding bearing is v interposed between their adjacent ends.

4. A refuse vehicle in accord with claim 1 in which the separate conveyor driving shafts are axially aligned and the double motor driven clutch section is mounted to slide on but to turn with both conveyor driving shafts,

and the separate conveyor clutch sections are mounted to slide on but to turn with the respective conveyor driving shafts.

5. A refuse vehicle in accord with claim 1 in which the means for engaging and disengaging the separate conveyor clutch sections from the motor driven clutch section, consists of a separate cam follower for each conveyor clutch section and a movable plate having separate, cam-slots for the separate cam followers.

In testimony whereof I alx my signature.
