The originalapplication .upon which this application is based was a refile of my abandoned ap- 5 plication, filed on February 6, 1931, Serial Number 513,860. 1

The invention has for an object theprovision body for holding refuse, and a loading conveyor extending across the top and down the rear of the truck body.

The invention has for a further object to arrange the truck body for tilting upwards so as to be capable of dumping and to provide 'a rear door upon the truck body, and means for auto- -matically moving the conveyor section upon the rear of the body away to allow the door to, open during dumping. I

A still further object of this invention is to provide means to drive the conveyor in the down position of the truck body.

As a further object of this invention it is proposed to provide an' arcuate stationary rack! mounted upon the drivers cabin of the refuse and a gear in mesh with said arcuate rack and connected for transmitting motions upon upward tilting of the truck body to cause the rear section of the conveyor to be moved as above recited.

A still further object of this inventionis to arrange the conveyor into two sections, namely, a

stationary top section and a rear section which is hinged on the top section so as to be capable of swinging away from the rear of the truck body. 38' A still further object of this invention is 'to arrange a shaft to constitute the pintle pin for the pivotal mounting of the rear section of the conveyor, to fix a sprocket upon this shaft, and to connect the sprocket with a transmission system 40 to the gear before-mentioned which is in mesh with the arcuate stationary rack.

And this invention has for a still further object the provision of a refuse truck of .the class mentioned which is of simple durable construction, 45 dependable in use and efficient in action, and

which can be manufactured and sold at a reasonable cost.

Fig. 5 is a fragmentary sectional view taken on the line 5-5 of Fig. 1.

The refuse truck according to this invention consists of a truck in with a truck body II. The details of the truck lllare not shown nor will they be described fully since they form no part of this invention. To help persons skilled in the art to recognize the truck; various familiar parts will be reviewed. The truck Ill is shown with a chassis l2 supported by wheels I3. It is also provided with a drivers cabin M in which there is a steering wheel IS, a hand brake I8, and a shift I]. To the front of the driver's cabin, a radiator I8 'is shown and to the front of this the conventional borne in mind that this'truck must be fully equipped as is conventional for its operation.

A means is provided for tilting the body II to dump from the rear.

This means is not shown in great detail, since it also forms no part of this invention and is generally known to those skilled "in the art. It is suflicient to state that the body H is mounted upon transverse beams 23 which in turn are supported upon longitudinal beams 24. The longitudinal beams are hinged at 25 upon the chassis [2 of the truck. This allows the body to tilt upwards to a position for example as illustrated by the dot and dash lines 26.

Atransmission system 30, not shown in detail on the drawings, controllable and operable from the motor of the vehicle as is conventional may serve 'to tilt the body to position 26.

A member 31 for closing the rear of the truck body H is hingedly mounted at its top .33 upon ,the' truck body. Catches 34 serve to normally hold the member 31 closed. A loading conveyor -35 extends across the top and the rear side of the body I I. This conveyor is arranged within a casing formed with a topsection 36 which is fixed upon the top of the truck body II and a rear. section '31 which is hingedly connected with the 40 Y mounted and serves to keep the chain 50 in tenported in the sides of the casing section 31.

. ing of the section fl'.

The conveyor 35 consists of bottom sprockets 42.rotatively mounted in blocks resiliently sup- Top sprockets 43 are resiliently supported in blocks mounted upon the sides of the, stationary casing section 38. Intermediate sprockets 44 are rotatively supported upon the casing section 38, and front sprockets 45 are r'otatively mounted in blocks resiliently supported at the front of the casing section 38.

An endless chain 45 extends over the sprockets '42, 4a and 4s and against the sprocket in an endless fashion as shown in Fig. 1. From the chains there projects a plurality of conveying blades or buckets 41 which are capable of lifting and carrying refuse from the bottom of the casing section 31' up across the top of the-body ll of the truck. The spaces between the blades 41 are opened and the blades themselves'are dB? pended upon to do the conveying. The chains 45 are supported upon guides 48 and 49 within the sides of the casing section 36, as clearly shown in Fig. 4. This prevents sagging of the chains which would interfere with their eiilcient operatibn.

A means is provided for driving the conveyor and comprises a .driver gear fixed upon the shaft which supports the sprockets 45. A chain Bil engages over this driver gear and over another gear 5| which is upon a; shaft having a bevel gear 52 projecting slightly through the bottom of the truck body II. An idler I3 is resiliently sion. A bevel gear 54 is fixed upon a vertical shaft and connects with a transmission, system dash lines 24 freely, since in such event the bevel.

gear I52 merely disengages from the bevel 54.

Another means is also provided for driving the conveyor, consisting of a bevel gear 54' connected with the transmission system ll. Bevel gear I4 meshes with a bevel gear 54 fixed on one end of a horizontal shaft SI. 9n the other end of shaft 55' a clutch member I1 is adapted to mesh with a corresponding clutch member which drives axle 42' of sprocket 42 through bevel gears 42'.

Either one or the other driving means for driving the conveyor maybe used alone, if so desired.

A means is also provided .for automatically moving the conveyor sections 31. away from the.

cases with a transmission system 83 which extends to the top of the casing section 38 and terminates in a sprocket wheel 84. The truck body II has a chamber divided on by a partition 65 to accommodate the drive system 63. The details of the system will not be gone into in that it consists merely of rotatively mounted shafts provided with bevel gears which mesh with each other. A sprocket chain 66 engages over the sprocket wheel 64 and over a sprocket wheel 81 upon a pintle shaft 88 which is mounted in blocks 89 upon the sides of the'casing section 38. Rigid levers 10 project from the shaft 68 and are rigidly attached upon one of the sides of the casing section 31 so that upon turning ofthe shaft the casing section is moved to an opened position. Dot and dash lines Ii indicate the opened position of the casing and the dot and dash lines III indicate the moved position of the rigid levers 1D.

The conveyor section 31' may also be operated automatically by suitable cables or wires connected near the driver's cabin H;

The operation of the device may be traced by assuming it in the position as shown in full lines in Fig. 1. Refuse may be dumped into the inlet spout i8 and be fed up by the blades 41 of the conveyor. It is requisite that the conveyor work in an anticlockwise direction so that the blades scoop up material from within the bottom of the casing section 31, lift this material up and drop the material over into the top of the truck body ll. As the material piles up, the blades 31 will also serve to spread the material out towards the front of the truck body.

To empty the truck, the body ll may be tilt upwards by the conventional controls. As the body tilts upwards, the gear 62 rides along on the stationary rack so that it rotates and these rotatlonsare transmitted by the system ll to the sprocket 8,4. The motion continues from the sprocket to the sprocket B1 and the shaft I8. As the shaft 68 turns, the lever Iii-will cause the casing section 31 to tilt away from the body ii of the truck so that the rear may be opened for the dumping.

While I have shown and described the preferred embodiments of my invention, it is to be understood thatI do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
