To all whom it may concern: 7

. Be it known that we, HENRY BARKMANN, a citizen'of the United States, and Arms KUTSOHA, a citizen of the Republic of Germany, both residing at Chicago, in the county of Cook and State of Illinois, have'invented certain new and useful Improvements in Autotrucks, of which the following is a specification.

Modern auto trucks for hauling coal and other loose material are generally constructed for discharging the load at the rear or at the side of the box body. Some trucks are provided with meansgfor elevating the for-; ward endof the body to tilt the body and facilitate unloading. Owing to the congested condition of many city streets and alleys, to trafiic regulations, and to other conditions affecting the unloading operation it is frequently impossible to back atruck up so that the load may be discharged at the rear and hence the provision of meanswhereby the load may be discharged at the side when the truck is stationed alongside a street curb or in a narrow alley. But there are many times and places whereit is desirable to deliver the load to a point at some distance from the truck and chutes are employed for this purpose. If the chute is comparatively long the fall will often not be suflicient to cause the coal to slide and a man must stand by and push the coal down the chute to avoid clogging and to keep the coal moving. Sometimes it is desirable to deliver the load through a chute adjusted to a substantially level plane, or even to elevate it through an upwardly inclined chute. In view of the large investment involved in auto trucks,

"and the employment of high priced labor for operating them, as well as to comply v with traflic regulations, it is highly desirable to accomplish the unloading-operation as speedily as possible so that many trips may" be made daily and the obstruction of trafiic reduced to a minimum. And, as before indicated, it is also desirable to provide for delivering the load at a distance from the truck to coal holes or other places more or 'less inaccessibly located, and without requiringany handling of the..mater1al dur with a bevel gear 24 on the screw 12. The

ing the unloading operation.

It is the primary object of our inventlon to provide an auto truck with a readily attachable conveyor and-with means. whereby the conveyor may be operated from the truck motor so that the truck load may be mechanically and automatically discharged from the rear'or from the side of the truck and delivered to any desired point.

The invention has other objects in view which will, appear hereinafter in the detail description of the invention as embodied in a selected form in the accompanying drawings, in which- Fig. 1 is a side elevation of a truck in discharging position with the conveyor located at the rear end thereof;

Fig. 2 is a detail View showing the conveyor in storage position on the side of the truck body;

Fig. 3 is a rear elevation of a truck in discharging position with the conveyor located at the side of the truck;

Fig. 4 is a detail enlarged sectional view showing the truck body in horizontal position with the conveyor attached at'the rear end of the truck; 7

Fig. 5 is alongitudinal sectional view of a portion of a conveyor that may be employed; I j

Fig. 6 is a transverse sectional view of the conveyor;

Fig. 7 is a plan view showing as much of the truck frame as is required to understandthe invention;

Fig. 8 is a sectional view on the line 88 of Fig. 7 and Fig. 9 is a sectional view on the line 9-9 of Fig. 8.

We haveselected for illustrating the invention an auto'truck in which the body or box 10 is ,elevated'to tilted position relative to the truck frame 11 byscrew devices 12 operated by the motor driveshaft 13 through the transmission 14. The motor is not shown in the drawings and the transmission is only indicated generall as they are well known in the art and may he of many different kinds.

A shaft 15 is also driven from the transmission (Fig. 7) and is provided with a clutch 16 operated by lever 17. This clutchfshaft carries bevel gears 18, 18' which drive a gear 18 or the gear 18' is shifted into oper ative enga ement with gear "19 by means of lever-25 9) to rotate the screw forward or reverse and to raise or lower the body.

The mechanism thus far described forms no part of our invention and simply illustrates one form of truck operating mechanism with. which the invention may be embodied.

The clutch shaft la is provided with a sprocket wheel 26 to drive a sprocketchain 27 which travels on another, sprocket wheel 28 on a conveyor operating shaft 29 suitably mounted on the truck frame (Fig. 7). The conveyor shaft extends lengthwise of the frame and through a sprocket chaln 30 (Fig. 7) drives a side shaft 31 also mounted on the truck frame adjacentthe dischar'ge 32* at the side of the truck body near the rear end thereof. "A bevel gear '33 on the side shaft 32 meshes with. a bevel gear 34 on the rear shaft 35 mounted on the truck frame at the rear end thereof. This shaft-35 may be provided with a belt ulley 36 so that power may be taken there rom for various purposes. The side shaft 31 may also be provided with a belt pulley if deslred.

The conveyor comprises a suitable frame 37 having at each end a large roller 38 (and' one or more similar intermediate rollers if pended'in storage position at the si L of the body on supports 42, as shown in Fig. 2.

If the load is to be discharged at the rear I end of the truck, the truck body is elevated to tilted position andthe conveyor is sus pended in proper relation to the rear discharge 43 by one or more chains 44 and one or more hooks 45. One end roller -38 is mounted on a" shaft 38 which carries a sprocket 46 and a sprocket chain 47 is trained over this sprocket and over a sprocket 48 on the rear shaft 35.- Or if the load is to be discharged at, the side of the truck the prises a door 50 and as conveyor is similarly suspended and the sprocket chain engaged with a sprocket wheel 49 on the side shaft 31. In either case the conveyor is operated from the truck motor through the mechanism heretofore described.

The rear discharge may consist of. an opening-in the body closed by a swinging door 43. The'side discharge preferably comort chute having sides 51 and an angular bottom 52 which will be positioned horizontally to receive the conveyor when the body is tilted (Fig. 1).

Our invention is simple in constructiomthe conveyor can be easily and quickly attached and detached, and it is operated'by the truck motor by simply throwing clutch 16. .This

conveyor insures'delivery of the load to the desired location without handling and it avoids the necessity for discharging a load upon the street or alley, as now often happens, because of the impossibility of positioning the truck close enough to a coal hole or other depository. The conveyor may be arranged across a side walk and if not long enough it may discharge into an ordinary chute which will deliver the material to a more distant point. The outer end of the conveyor may be elevated to deliver the material to a higher-level than the discharge from the truck body. The pulley 36 may be belted to drive a loader for loading the truck;

Our invention will greatl facilitate the unloading operation and ena le it to be conducted with greater speed than hasbeen customary heretofore. The invention is especially important in connection with. the delivery of coal but "it may be used for many other purposes and it enables the delivery of the load in places where it cannot now be delivered direct from the truck. As before stated the operating mechanism on the 90. truck may be utilized to operate a loading machine and with the loading operation accomplished under power of the truck motor at one end of the line and the discharging operation conducted in the same way'at the other end of the line the work of delivering by auto truck will/be greatly expedited, a greater number of'trips may be made daily and a greater return on the comparatively large investment necessary to acquire and maintain an autotruck will be made.

The invention has been illustrated and described herein in a selected embodiment which we have found satisfactory for the purpose but it will be appreciated that changes in the construction and arrangement and proportionsof parts may be made withoutldeparting from the spirit of the invention and that some changes will undoubtedly be necessitated to adapt the invention for trucksof 'difi'erentconstructions, and we therefore desire to have it understood that we reserve the right to make all such changes and adaptations as fairly fall within the scope of the following claims.
