WILLIAM Y. GAMBEE, OF BROOKLYN, NEW YORK.

DUMPING-VEHICLE.

Application filed January 6, 1913.

To all whom it may concern Be it known that 1, WILLIAM Y. GAMBEE, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Dumping- Vehicles, of which the following is a specification.

The invention relates to improvements in vehicles or wagons for carrying refuse, such as ashes, garbage and other materials gathered by the street cleaning departments of cities, as well as other materials required to be conveyed, and more especially to a vehicle or wagon possessing mechanical means for efl ecting the discharge of the material from the vehicle or wagon.

I present my invention herein as embodied more particularly in a motor-vehicle adapted for the needs of street cleaning departments of cities, but do not of course limit the invention to the nature of the material that may be carried.

One object of my invention is to provide a vehicle or wagon-body of special construction adapted to the carrying of refuse and concealing the same and of avoiding either the blowing of the refuse from the vehicle by wind or the leakage of material from .the vehicle around the lower edges of its body portion.

A further purpose of the invention is to provide a vehicle having an endless carrier of special construction constituting the bottom of the vehicle body and arran ed to be operated by the motor of the ve icle for efiecting the discharge of the load. The endless carrier extends the full length and width of the vehicle-body and is of such durable construction that it may be safely depended upon for supporting and discharging heavy loads, and the construction of the carrier is such that it may be readily operated to discharge the load without imposing undue strain on the engine or motor or such other power as may be applied for eflecting the travel of the upper side of the carrier toward the discharge end of the vehicle body.

The invention will be fully understood from the detailed description hereinafter presented reference being had to the accompanying rawlnigs, in which:

Serial No. 740.359.

hicle constructed in accordance with and embodying the invention, one of the side curtains above the upper edge of the vehiclebody being shown in a partly open position; Fig. 2 is a longitudinal section on a larger scale and partly broken away, through the body portion of the vehicle on the dotted line 22 of Fig. 3; Fig. 3 is a vertical transverse section through the same on the dotted line 33 of Fig. 1; Fig. 4 is a horizontal section through a portion of the vehicle taken on the dotted line H of Fig. 1; Fig. 5 is a top view; partly broken away, of the side sills of the vehicle and presents in top elevation the endless carrier which I apply to the body of the vehicle as the bottom thereof; Fig. 6 is a horizontal section through a portion of the vehicle body, partly broken away, taken on the dotted line 6-6 of Fig. 2; Fig. 7 is a top view, partly broken away, of the endless carrier and its supporting mechanism; and Fig. 8 is an enlarged vertical longitudinal section through a portion of the carrier and connecting parts taken on the dotted line 88 of Fig. 5.

In the drawings 10 designates the vehicle body as a whole, 11 the side sills of the vehicle, 12 the usual supporting wheels, and 13 the usual motor features not necessary to describe, the same being common to motor vehicles and not per se claimed by me.

The body 10 will preferably be formed of sheet metal and comprises sides 14, a front end 15 and a rear door or gate 16 hinged at its upper end, as at 17 and adapted to be secured in closed position by any convenient latching means 18.

The sides 14 incline downwardly and inwardly, as shown in Fig. 3 and are strengthened by vertical T-bars 19 secured thereto and at their lower ends to the side sills 11. The sheet metal sides 14 have along their lower portions supplemental sideplates 20, between which and the main sides 14; are spaces or chambers 21 (Fig. 3) for certain operative features hereinafter described.

The front plate 15 of the vehicle body inclines downwardly and inwardly (Fig. 2) and has strengthening T-bars 22 and along its lower portion a supplemental plate 23 between which and the main front plate 15 is a space or'chamber 24, for the purpose hereinafter described.

' rods 34, which superimposed structure forming an upper extension thereof and comprising a roof 29, ends 30 and side curtains 31 secured on spring curtain-rollers 32 (Fig. 3) of usual type and which curtains may be raised or lowered at will. It is the intention that the curtains 31 shall be in their lower closed position during the travel of the vehicle, aftena load has been gathered, so as to conceal the refuse in the vehicle-body and prevent the wind from blowing particles thereof about, and in the use of the vehicle it is the purpose that only such curtain as may be necessary shall be in its upper or open position to permit the dumping of cans into the vehicle-body, thus during the gathering of refuse the curtains being employed to as far as possible conceal the refuse in the vehicle-body and prevent particles thereof from being blown about.

The bottom or bed of the vehicle body comprises an endless traveling belt 33 extending the full length and Width of said body and preferably formed of a good quality of rubber, as shown in Fig. 8, having embedded in it parallel transverse metal are reasonably close together and pro ect at-their ends beyond the side edges of the belt 33 to receive the links of the sprocket chains 35, as represented more clearly in Fig. 7. The sprocket chains 35, one being at each side edge of the belt, are mounted on sprocket wheels 36 secured upon the front and rear shafts 37 carrying, between the sprocket wheels, rollers or drums 38 upon which is mounted an endless chain of metal rollers 40 whose ends are connected together by chains 41 carrying at the joints of their links studs 42 which enter the open ends of the hollow metal rollers 40 and permit said rollers to have freedom for rotary movement thereon. Immediately below the upper side of the chain of rollers 40 is provided a frame composed of longitudinal bars 43 and transverse bars 44, shown by dotted lines in Fig. 5, for firmly supporting said side of the chain and the upper side of the belt 33 superimposed on said chain. The

' longitudinal bars 43 are supported by the transverse bars 44 and the bars 44 are, at their ends, secured to the side sills 11, as clearly represented in Figs. 2 and 3. During the travel of the belt 33 it is close against the transverse rollers 40, as shown in Fig. 8, and causes said rollers, as a chain, to travel on the drums 38 and also to rotate individually on the studs 42, thereby avoiding excessive friction between the belt 33 and chain of rollers 40, and permitting said rollers to at all times cooperate with the belt both as to its traveling motion and its proper support. The belt 33 is driven through the chains 35 from the sprocket wheels 36, and the chain of rollers 40 has only such movement imparted to it as it receives from the belt 33 and plain surfaces of the drums 38. The rollers 40 ride on the drums 38 and longitudinal bars 43 and aid materially to the efficient action of the belt 33. The shaft of the front sprocket wheels 36 is mounted at its ends in adjustable bearings 45 (Fig. 4) so that the belt 33 and chain of rollers 40 may be kept taut. The bearings 45 may be of any appropriate construction, but I illustrate them as being formed on sliding bars which are adjustable by means of bolts 46. I do not, however, limit the invention to any special means for tightening the belt 33 and chain of rollers 40. On the outer end of the shaft of the front sprocket wheels 36 is secured a gear wheel 47 through which said shaft and the sprocket wheels thereon may be driven by any suitable power. I shall preferably drive the shaft 37 and the front sprocket wheels 36 by power from the motor carried by the vehicle, and this power may be transmitted to the gear wheel 47 through a sprocket chain 48 and pinion wheel ,49, the

latter being in mesh with the gear wheel 47.

The power will be transmitted to the sprocket chain 48 from the usual shaft 50 provided on motor vehicles and from which, through a chain 51, power is transmitted to the driving axle of the vehicle. \Vhen the vehicle is in motion power should not be transmitted to the sprocket chain 48, and when the vehicle is at rest and it is desired to discharge the load, the usual motor will be kept in motion, as is common practice, and the power therefrom will be cut off from the driving chain or chains 51, and by means of a clutch member 52,-t ransmitted to the sprocket chain 48 andby said chain to the pinion wheel 49, gear wheel 47 and front shaft 37. The clutch member 52 may be of any of the many kinds commonly used and may be operated from the front of the vehicle body by means of a crank or handle 53. I do not limit my invention to any special power devices for operating the belt 33, since obviously these will vary in accordance with the nature and size of the motor vehicle and other conditions. I therefore indicate diagrammatically merely that it is my purpose to operate the belt 33 to discharge its load by power obtained from the usual motor for driving the vehicle.

One important feature of my invention relates to the provision of means for preventing leakage along the lower edges of the vehicle body, and to this end I provide a three-sided or U shaped' frame 54 extending along the opposite sides and front end of the vehicle body, the front end of said frame being within the space 24 formed in the front of said body and the sides of said frame being in the spaces or chambers 21 formed between the plates 14, 20 of the sides of said body, as clearly represented in Figs. 2, 3 and 6. The frame 54 is suspended by pivoted links 55 and has secured to it, along its entire length, a strip of rubber 56 which is of angle shape in cross-section and has its horizontal member extended inwardly upon the side and front end portions of the belt 33. The strip of rubber 56 is a sealing strip for engaging the upper surface of the belt 33 and preventing; during the travel of the wagon any leakage along the sides or front end of the vehicle body. The rubber strip 28' carried by the plate 26 forming a part of the rear gate 16 is also a sealing strip and it, by its engagement with the rubber belt 33, prevents leakage" from the wagon body at the rear end thereof. The strips 28, 56 become pressed closely against the surface of the belt 33 by the closing of the gate 16'. The rear ends of the side members of the frame 54 normally stand in the path of the gate 16' (Fig. 6), and when the gate is closed, it will press against said ends of said members of the frame 54 and cause said frame to move inwardly to the slight extent required for carrying the sealing strip 56 firmly against the belt 33. When the wagon is to discharge its load and the gate 16 is open, the traveling movement of the belt 33 to carry the load rearwardly and eject the same from the vehicle body, will by its frictional engagement with the strip 56, cause the frame 54 to move slightly rearwardly and upwardly, said frame being suspended by pivoted links, and at such time the strip 56 will not act materially to retard the traveling action of the belt 33. The slight movement rearwardly of the frame 54 by the action of the traveling belt 33, causes the rear ends of the side members of the frame 54 to project rearwardly to a slight extent in the path of the rear gate 16. After the load has been discharged and the gate 16 1s again closed, it will, during its final closing movement, press against the rear ends of the side members of the frame 54 and move said frame inwardly, with the result of causing the sealing strip 56 to be again depressed against the side and front edge portions of the belt 33. The frame 54 with its supporting links, by being confined within the spaces or chambers 21, 24, are protected from injury by the load that may be placed in the vehicle body, and hence may be kept in 0perative condition without special care and without inconvenience to the loading of the vehicle. The sealing strip 28 is within the chamber 27 formed between the two plates of the rear gate 16, and the sealing strip 56 is substantially'confined and concealed within the chambers 21, 24 formed along the sides and front of the vehicle body. The sealing strips 28, 56 are desirable of use whether the vehicle is being employed for carrying either dry or wet refuse, since in either event said strips prevent the sifting out or leakage of the refuse around the'lower edges of the sides and ends of the vehicle body.

The method of employing my invention will be understood from the foregoing descriptionwithout further detailed explana tion. vehicle body from over the side edges thereof, a curtain or curtains 31 being raised to permit cans or barrels being tilted to discharge their contents into the vehicle body. It is my purpose that the curtains 31 shall be kept-down to as great an extent as possible so as to conceal the contents of the vehicle and prevent wind from blowing the same about. The belt 33 forms the bottom of the vehicle body and receives upon it the load of material. When it is desired to discharge the load from the vehicle body the rear end gate 16 will be opened and power will be applied either from the engine of the motor vehicle or other source to effect a traveling movement of the upper side of the belt 33 toward the rear end of the vehicle body, and this traveling movement of said belt will cause the load to be discharged, as will be obvious. One of the main features of the present invention is the provision of an entirely efficient and durable movable bottom for the vehicle body, this bottom comprising the belt 33, supporting chain of rollers 40, and supporting frame comprisingthe longitudinal bars 43 and transverse bars 44 for supporting the upper sides of the chain of rollers and belt 33. The construction' presented by me is adapted for the carrying of heavy loads of refuse and of being employed by the street cleaning de- The refuse will be thrown into thepartments of cities for conveying refuse to its place of deposit and there discharging the same with the minimum labor and expense.

I do not limit my invention to all of the details of for and construction presented in the drawings'and hereinbefore described, since I am aware that changes may be made in the detail of form and construction without departing from the spirit of my invention.
