ALBERT 1?. LEE, OF CHICAGO, ILLINOIS.

' MOVABLE LOADING-HOPPER.

Specification of Letters Patent.

Application filed January 1914. Serial No. 810,964.

To all whom it may concern Be it known that I, ALBERT P; LEE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Movable Loading Hoppers, of which the following is a full. clear. concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My inventionrelates to movable loading hoppers and has for its object the provision of a new and improved device capable of use for loading and unloading.

My invention consists primarily of a vehicle having one Or more hoppers, which hoppers are operable to occupy one or an- I other limiting position, thus to travel preferably from a loading to an unloading position.

My invention contemplates in onev of its forms certain features whereby the hopper may be reversible if desired, so as to change its loading or unloading positions from one to the other side of the vehicle.

My invention in one of its forms also contemplates the provision of means whereby the hopper may be raised or lowered upon the vehicle to accommodate for proper loading and unloading.

' My invention also contemplates means whereby after the hopper has been moved to its unloading position it may be slightly elevated to withdraw the snout of the hopper from the deposited material.

I will explain my invention more in detail by. referrin to the accompanying drawings, illustrating the same in which:

Figure 1 is a side view of a vehicle constructed in accordance with my invention; Fig. 2 is an end view thereof; Fig. 3'is an enlarged detail view illustrating the mechanism for shifting the hopper carrying framework; Fig. 4 is a sectional View. on

lines 'a--aof Fig. 3; Fig. 5 is an end view 'ofthe mechanism providedfor hopper reversing purposes, and Fig. 6 is a view partially in section illustrating an endelevation oftheystructure' illustrated in Fig. 5. i

Referring more particularly to Fig. 1, I show a vehicle consisting of the truck portion I mounted upon suitable wheels 2, 3.

The truck portion is also shown more clearly in Fig. 2 as carrying a plurality of struts 4, 5 and 6 adapted to support a shaft 7. Upon this shaft 7 a pair-of tilting beams 8 may be.

are mounted, which tilting beams for this J purpose are each provided with a bearing 9 suitably fastened to said tilting beams. Surmountmg the struts 4; and 6 are posts 10 which pivotally support a rod or pipe 11. Thls rod is provided at its opposite extremities with a T 12, from which T pipes or

rods

13, 13 extend in opposite directions whose extremities pivotally rest in sockets 14, 11 provided therefor in the frameworks 15 for supporting the hoppers l6 and 17. These

frameworks

15, 15 are pivotally connected by shafts 18 mounted in the

tilting beams

8, 8. It will be seen now that the frameworks 15, being pivotally supported upon the tilting beams 8 and being also associatedwith the posts 10 by means of the rods 13, that these frameworks 15 will at all times occupy a substantially vertical position if the vehicle stands in a horizontal position. The tilting bars 8 are each provided with a framework 19, which carry at their lower extremity a segmental gear 20 adapted to mesh with

pinions

21, 21, which pinions are carried by a shaft 22 supported in brackets 23 carried by the truck body 1. A shaft 22 also carries a ratchet wheel 24: adapted to be engaged by pawls 25 and 26 controllable respectively by the hand holds 27 and 28 vmounted upon the. rocking bar 29, which rocking bar is also pivotally:

mounted upon the shaft 22.. It will be seen thus that by operating the handle 29 and releasing one or the other of the-pawls, that the shaft 22 may be rotated to thereby cause a gradual tilting ofthe tilting beams 8, thus elevating one hopper 16, for instance, and lowering'the .other, or vice versa, as the case agency of

rods

32, 32 controlled by handles '34, '34, may be withdrawn from engagement with their ratchetwheels 30. The purpose of these ratchet wheels. 30 is to hold the gear wheels 21 in any position set so that the tilting bars 8 maintain whatever position isgiven to them through the actuation of the actuating lever 29. When both pawls 31 are in engagement with the teeth of their respective ratchets 30, then of course the shaft 22 is locked against rotation in either The shaft 22 also carries a pair. of ratchetsi30 adapted to be engaged by the '

pawls

31, 31 respectively, which through the adapted to roll, these hoppers being provided with channels 36 for that purpose.

Referring more particularly to Fig. 2, it will be seen that these rails terminate in fingers 37 adapted to engage pins 38 mounted upon the hoppers 17 to prevent the hoppers from entirely leaving the rails when these hoppers are moved into them limiting positions for unloading, as shown more clearly in Fig. 2. The hopper shown in full lines in Fig. 2 is supposed to be in the loading osition. When in this posltlon the hopper 1s held by means of chains 39, shown more clearly in Fig. 1, which chains are held in place by fingers 40, to thus prevent the hopper 17 of Fig. 2 from rollin to the right. When the hopper is fille then the finger 40 is released from its engagement with the chains 39, whereupon the hopper either due to its own over-balanced condition, or with the help of a slight push, rolls into the position shown in dotted lines in Fig. 2, to be held by the fingers 37 and the chains 70. Chains 42, 42 are provided to limit the upward and downward movement of the rocking bars 8. In order to actuate the fingers 40 it may be stated that these fingers form part of arms 42, which arms are pivoted at 43. These arms are linked to a further arm 44 under the control of a lever 45 pivoted at 46. Now whenever the right hand lever 45 of Fig. 1, for instance, is moved in a contra-clockwise direction, it naturally moves the arm 42 in a contraclockwise direction about its pivot 43, thus elevating the finger 40 and permitting the chains 39 to slide away from engagement with said finger 40. As has already been stated, the hoppers are so constructed that they roll either of their own initiatlve from the loading to the unloading position.

Now it may be desirable instead of havmg the loading position to the left of the vehicle, as shown in Fig. 2, to have the loading position to' the right of the vehicle. In order to accomplish this, I reverse the position of the hopper 17 upon the rails and this 1s done by means of the trough 47 pivotally carried upon a screw threaded stud 48, which finds screw threaded'engagement with the screw threaded socket 49. This socket is carried by the shaft 18 and thestud 48 travels loosely through the bridge 50. The stud 48 has a collar 51 provided with an aperture 52 so that when a bar is inserted into this aperture the stud 48 may be rotated to elevate the trough 47, which thereupon engages the hopper 17 and thereupon lifts the same clear of the

rails

34, 35. Under these conditions the hopper 17 and the trough 47 may be rotated about the stud 48 into the reverse position, at which time the stud may be again lowered to permit the hopper to rest upon the

rails

34, 35. During this reversal, of course, the chains must be loosened and at- 'hopper when discharging. From what has been described it is thought the nature of thls stationary loading mechanism will also be apparent.

Haying however thus described my invent1on, it will be clear that it is susceptible of many and variousmodifications without departing from its spirit.

Having however thus described one form which my invention may take, what I claim as new and desire to secure by Letters Patent 1s:
