TRUCK.

Application led July 13, 1922. Serial No. l647,752." 'n

To. aZZ 'whom it. may concern:

, Be it known that we, HENRY BABKMANN and ALoIs KU'rsoHA, citizensv of the United States, residing at Chicago, in the county'of Cook and State of Illinois, certain new and' useful Improvements in Trucks, of which the following is a. specification.

The object of this invention is broadly to equip trucks with a conveyor that will `always be in proper position for use and that can be driven from the power of the truck.

A further object of the invention is to provide a `conveyor mounting suitable for application Ato conventional trucks having tilting bodies and that will maintain the receivingend of the conveyor in suitable relation to thedischarge opemng or outlet of the;

body and permit the driving mechanism for the conveyor to be always in operative condition regardless of the position of the body relative to the chassis.

A further object of the invention is to provide a mounting for a conveyor that will accommodate itself to the movements of the body in dumping and that will maintain the conveyor always at the highest level that the `position of the discharge opening or outlet will permit.

Further objects of the invention will be-v come apparent as the description is read in connection with the accompanying drawings illustrating selected embodiments of the invention, and in which- Fig. 1 is a'side elevation of a portion of a truck shcwing the parts in traveling position in solid lines and in dumping position in dotted lines;

Fig. 2 is a plan view illustrating the drivin'g connection between the power mechanism of the truck and the conveyor;

Fig. 3 is a rear elevation showing the parts in traveling position;

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 1;

Fi 5 is an elevation similar t'o Fig. 1`

showing a modified construction;

Fig. 6 is a section on the line 6-6 of Fig. 5; and

Fig. 7 is a fragmentary detail.

Referring to Figs. 1,2, 3 and 4, 10 indicates the wheels of the chassis including a Aframe 11 on which is pivotally'mounted a 5 body comprising a 5 frame 12, transverse beams 13 and a box 14. The rear end of the side members of the frame 11 are equipped have invented with brackets l15 which'support a.' shaft 16 on whiclithe frame12 is pivoted. -In some trucks the shaft 16 is in the form of two ing the invention to those trucks a shaft may be suitably supported in line with the studs or they may be replaced by a continuous shaft lasshown.'

The rear end of the box 14 is equipped with'k a dischar e outlet or opening normally closed byY door 1 being discharged. We prefer to equip'thisy outlet or o ening with a lfixed chute consisting of t e bottom 19 and the side pieces 20'. i i

A conveyor 21 of any suitable construe-V' tion' is pivotally mounted onu the body adjacent to the discharge outlet or opening an which is hinged at 18 to swing'upwardly and rearwardly when' the loady isV studs secured tothe frame 12 and in applyvr00 is swung toand from unloading posit-ion by the cables 22 runningover pulleys 23 on the conveyor and having one end fixed to` the body at 24 and the other end to a drum` 25 which isv equipped with acrank 26 and a pawl 27., Suitable hooks or other fast'enings 28 may be used to relieve the cables when the truck is traveling. Preferably the lower end of the conveyor is equipped with a shaft 29 mounted in brackets 30 which are suitably fixed to the body frame 12 as by rivets 31. The conveyor-'belt 32 passes over a suitable mg side q hubs 36 in which the shaft 29 is journalled in suitable bearings.

ldrum 33 carried' by the shaft 29 and is equipped with battens 34. to assist inretainthe material on the belt. Preferablytheo frames 35 of the conveyor are fitted with".

When mounted in this way, the conveyor may easily swing from the solid to the dotted lowered to discharge position the dapper will extend as shown .in dottedy lines in Fig. 1.

In order to drive the 'conveyor a shaft 38v is suitably. supported in the chassis' frame asl by a bracket '39 fixed to the cross piece 40 and carries at its rear end a beveled gear 41 adapted to mesh with a beveled gear 42 journalled on the shaft 16 or otherwise supported in alignment with the axis of the pivot between the body and the chassis. The gear vention as the drivingfshaftyfor the conveyor. f

By including in the driving connection for the conveyor some element that is rotatable about 'the' pivotal axis of the body, the driving mechanism will automatically accom1no date itself to themove'n'lents ofthe body and ywill drive the conveyor-in any positionof the body relativev to the chassis.v Furthermore, it will be notedv that the length of the drivingconnection exemplified by the chain 44 is constant for all positions of the body the body, 4it is made to swing with thebody in dumping;V and the receiving end of the conveyor is maintained at all times in proper relation tc the discharge outlet or opening of thebod This arrangement permits the conveyor to be quickly put in discharge position and driven either "concurrently with the movement of the body or independently' thereof, so that the load or -any suitable portion of the load may be quickly delivered at any height within therange of the particular conveyor used. The drumand cables permit the conveyor to be easily lowered to the desired angle under perfect control and also' enable it to be raised to traveling position with a minimum of labor on the part of the operator. The hooks or fastenings 28 relieve the cables when the truck is traveling but inasmuch as the conveyor is in substantially vertical position, there is no great strain on-.these hooks or on the cables in case the hooksfare removed.

The brackets 30 may be of any form necessary or desirable in supporting the conveyor on the body of any particular truck. When the truck frame is short. or does not lend itself to the attachment ofbrackets, such as shown,they may takethe form of links runnmglforward to'some suitablepoint'of at- *tachment and inth'at'orany other case it mayl bedesirable to addstrapswrunningA-from thefh-ubsBG tothe backendof the box asindicated at 46. The gist lof the invention is in supporting the receiving end of the conveyor and conveyor. By pivoting the conveyor on the links 56 to the brackets4 inv proper relation to theV discharge outlet and including in the driving mechanism some element thatwillrotate withthe vbody about the axis of the shaft 16 so that the driving mechanism can automatically accommodate itself to the movement of the body and not require any connection or disconnectionl during the normal operation of the invent-ion. A

In Figs. 5, 6 and 7 we have shown another form of the invent-ion to illustrate how similar results may be obtainedy when for any veyor 55.- Straps 5.6 also pivoted on the hubs l 54 have their upper ends pivoted to brackets 5 7 fixed to the back end of the body boX 58. 'lhe box is equipped with azdischargein the back end normally closed-by the door 59 hinged at 60 adapted to swing open to permit the material in the body to pass out on the conveyor. f' v A chute 6l is pivoted at its forward end on the conveyor at 62 and supported at its rear end by links (S3 pivoted vto the links 53 and to the chute. By this arrangement the chute automatically adjusts itself in position to assist the material passing from the body to land properly on the conveyor. The front kind of the chute is preferably fitted withy a 'iapper 64 adapted to cooperate with the bat-y tens 65 to insure the proper feeding of the material on to the conveyor.

The shaft. 66 corresponding to the shaft 38 is equipped with a sprocket 67 driving a chain 68 running over a sprocket 69 on a shaft 70 supported in brackets 71 and 72 beloo low the frame 47. The shaft 70 drives the shaft 52 through beveled gears 73 and a chain 74 passes over sprockets 75 and 76 on the shaft 52 and the conveyor shaft 77 respectively, It will be noted that in' this movement"y also the length'of the driving connection exemplilied by the chain 74 is constant for all positions veyor.

The rear ends of the links 53 may be ofthe body and conforked as indicated at 78 to receive theshaft 52 or a suitable fixed bearing brackets oted at 8O onthe link so that they may carried by the .swing into the position shown in Fig. 7 and be secured by bolts 81. By`means of this connection and the use of is v'made readily attachable and detachable so thatit can be used or omitted with very little trouble.A

The conveyor is lowered and raised by 51, and-the hooks 79 may be pivbolts to securev 57 the conveyor' 82 similar to those shown at 22 inlFig.

l and .is held in traveling position by a chain 83 orgother suitablemeans like hooks 28.

This embodiment of the invention permits the conveyor to be attached to a' truck vhaving a dumping body so mounted that it is not feasible to use the arrangement shown in Figs. 1, 2, 3 and 4. The positions of the shaft52 and the brackets 5i -are variables that can be changed to suit particular conditions.. The nearer shaft 52 is tothe axis of the pintles 50 the less will be the relative movement between the receiving end of the conveyor and the discharge outlet of the bodyly In most cases it will be possible to locate this shaft very near the axis of the intles so that the movement of the receivmg end of the conveyor will be so small as to be negligible. When the shaft 52 is coincident withl the pitles 50 the arrangement will be substantially the same as that shown in Figs. 1, 2, 3 and 4. In fact, the rear ends of the frame members 12 and the brackets 30 disclosed in the preferred form are the equivalent of links pivoted tothe shafts 16 and `29 and may be considered as such links. In some trucks brackets 57 can be so located with reference to the axis of the pintles 50 that their movement is principally horizontal and in that case'the lowering of the conveyor relative to the body will be correspondingly less than in the embodiment illustrated in Figs. 5, 6 and 7 where the movement of these brackets is largely vertical. In some cases it may be desirable to have the links 56 extend between the shaft 7 7 and the pintles 50 in which case there will be no movement of the receiving end of the conveyor relative to the chassis when the body is swung about the axis of the pintles.

From these two examples it will be clear that we have produced a mounting for a conveyor that will permit it to be always in proper'position to receive material discharged from the body and will make, it possible to use a driving connection that can automatically accommodate itself to the movements of the body and the conveyor from traveling to discharge position.
