HENRY L. FERRIS, 0F HARVARD, ILLINOIS, ASSIG-NOR TO HUNT, HELM, FERRIS & COMPANY, OF HARVARD, ILLINOIS, A CORPORATION OF ILLINOIS.

FEED AND LITTER CARRIER.

Specification of Letters Patent.

Patented Mar. 18, 1913.

To all whom it may concern Be it known that I, HENRY L. FERRIS, a citizen of the United States, residing at Harvard, in the county of McHenry and State of Illinois, have invented a new and useful Improvement in Feed and Litter Carriers, of which the following is a specification.

My invention relates to certain new and useful improvements in feed and litter-carriers, and is fully described and explained in the specification and shown in the accompanying drawings, in which:

Figure 1 is a front elevation of the device; Fig. 2 is an end view; Fig. 3 is a vertical section through one of the hangers; Fig. 4 is a section-on the line 4, Fig. 3; Fig. 5 is a longitudinal section through the tripping mechanism; Fig. 6 is a section on line 6 of Fig. 5, and Fig. 7 is a section on line 7 of Fig. 5.

Referring to the drawings, 5 is a track upon which is mounted a trip-block 6.

7 and 8 are groove-rollers running upon the track and supporting hangers 9, each of which depends from one side of the corresponding roller and is turned in to a point beneath the line of the track and provided with a depending swivel pin 10.

11 is a U-shaped frame made of outwardly facing channel iron, same having brackets 12 perforated to receive the swivel pins 10 and to be supported upon heads at the lower ends thereof and each having its lower end extended laterally outward to brace the frame. Each bracket 12 has at its upper end a notched flange 13. Each hanger has pivoted upon it a locking-device 14 pivoted at 15 and spring-pressed to the left as viewed in Fig. 3 by a spring 16. Each locking-device 14 has a downwardlyprojecting finger 17 adapted to engage a" notch in the flange 13 of the bracket 12 and it has a hook 18 which lies underneath the track to prevent the roller from jumping the track. The end of each hook 18 is provided with a tip 19 which is adapted to be engaged by a flange upon a curve for the purpose of depressing the hook 18 so that the carrier may pass around the curve, and this same action disengages the finger 17 of the locking device 14 from the corresponding notch in the flange 13, so asto permit the hanger to swivel.

Vertically movable on the lower ends of the U-shaped frame 11 are journals 20 held in any of a series of vertical positions by means of pins 21. Between the journals 20 is pivo-tally mounted a tub 22. This tub, in the preferred form of construction, has at its upper edge a rectangular frame of outwardly facing angle iron, that is, angle iron with its angle at the upper inner corner of the frame. The main body of the tub is made of a single sheet of metal, bent into generally semi-cylindrical form and riveted to the inside of the longitudinal members of the frame 23. Heads 25, conforming to the cross-section of the tub and flanged outward at 26, are set in from the ends of the sheet 24, the flange 26 being riveted to the sheet 24 and the upper edge 25 being riveted to the ends of the angle-iron frame.

27 are tub-locking members adapted to engage with notched members 28 on the tub. The tub-locking members 27 surround the legs of the U-shaped frame so as to be vertically movable thereon and they are formed with hooks 29 which engage perforations in straps 30, which straps are connected at their upper ends to chains 31. The locking members 27 are held downward by springs 32 connected to the movable journals 20. The adjacent ends of the chains 31 are connected to a trip-member 32 vertically movable in a central guide 33 on the upper part of the frame, said guide having rounded chain guides 34. The upper part of the tripping member 32 is adapted to be struck by the trip-block 6 so as to be depressed whereby to shorten the effective lengths of the chain 31 and elevate the locking member 27 for the purpose of releasing the tub. The lower end of the trippingmember 32 is connected to a bell-crank lever 35 and also to a spring 36 attached to the U-shaped frame and so arranged that when the tripping member is elevated it lies practically at the line of the lever pivot, and when the tripping member is depressed on one side of the center of the bellcrank lever 35, so that when the tripping member is up it is held stationary by this'spring, but can be moved down by a very slight pressure, and when moved down slightly, it will continue to move down to its limit, so as to clear the trip-block for returning the tub.

The result of this construction is that the tub will be tripped in an obvious manner by engagement of the tripping member with the trip-block, the carrier will return freely without being interfered with by the tripblock and the tripping member can readily be returned to its normal position by hand manipulation of the lower arm of the bellcrank lever.

In the use of feed and litter-carriers on flexible tracks, there is a tendency for the carrier to run to the center of the space between any two supports, especially when the carrier is subjected to weight, because the central point will be the point at which it can be the lowest. This tendency gives rise to considerable inconvenience and for the purpose of remedying the diflioulty, one of the rollers 7 and 8 is provided with projecting flanges 37 provided with hooks at or near their ends. Pivoted to one of the hangers is a dog 39 having at its end a pin adapted to be engaged by the hooked ends of the ribs or flanges 37 so as to prevent a rotation of the pulley or roller and consequent movement of the carrier upon the track. WVhen any tendency of the carrier to move is observed, the pin on the dog 39 is elevated into engagement with the corresponding rib or flange by means of a depending chain 40, and the parts will automatically remain in engagement without further 'difficulty. When it is desired to release the carrier, it is moved backward a slight distance and the dog automatically falls out of position setting the carrier free.

I am aware that considerable variation 1s possible in the details of construction here shown and while I have described it in detail as required, I do not thereby intend to. limit .myself to the specific form disclosed;m y intention being to the contrary to claim all the novelty which may be inherent in the construction as broadly as the state of the art will permit.

IVhat I claim as new and desire to secure by Letters Patent is- 1. In combination, a track, rollers to run thereon and provided with radial flanges, hangers carried by the rollers, a litter-carrier tub carried by the hangers, and a lock ing-dog pivoted on one of the hangers and adapted to be manually moved into engagement with one of the roller flanges to lock the roller against rotation, for the purpose set forth.

2. In combination, a track, rollers running thereon, hangers supported by the rollers, a tub carried by the hangers, a dog pivoted to the hangers and adapted to engage projecting flanges, said flanges being hooked so that when the dog is once in engagement therewith it will be held in engagement by the tendency of the carrier to move until the carrier is moved backward.

3. In combination, a track, a trip-block thereon, rollers, a frame, a tub pivoted in the frame, locking means for the tub, a vertically movable trip-member to engage the trip-block, flexible members connecting said trip-member and the locking means and adapted to be put under tension by the movement of the tripping-member, a bellcrank lever attached to said trippingmember and a spring adapted to swing off the dead center as the member is depressed, for the purpose set forth.

In testimony whereof I have hereunto set my hand.

HENRY L. FERRIS.
