BRAKE FOR REVOLVABLE CARRIERS.

Specification of Letters Patent.

Patented Apr. 16, 1918.

Application filed October 7, 1916 Serial No. 124,389.

To all whom it may concern:

Be it known that I, ANDREW H. Mnnnrr'r, a citizen of the United States, residing at Enfield, in the county of White and State of Illinois, have invented certain new and useful Improvements in Brakes for Revolvable Carriers, of which the following is a specification.

This invention relates to a brake mechanism and more particularly to a brake for a revoluble carrier of substantially cylindrical construction which is adapted to travel over the ground by a revolving motion.

A furthe object of the invention is to provide a brake mechanism. of this character that may be operated by a movement to a hand lever disposed in-a position whereby the operator may force the brake shoe of the device into a position for securing an effective contact with the tread portions of the carrier when the brake is to be applied.

Another object of this invention is to pro vide a brake mechanism for a revoluble carrier which is simple in construction but especially adapted to withstand the rough usage and strain to which it will be subjected while in use.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and the accompanyin drawings, wherein is illustrated the pre erred form of my invention, in which;

Figure 1 is a side elevation of the inven tion, showing the brake mechanism in applied position.

Fig. 2 is section through the carrier showing the treads and the relative position of the brake wheel.

Referring to the drawing, wherein is illustrated the preferred form of my invention, and in which like numerals of reference indicate corresponding parts throughout the several views, a large cylindrical container 1 is constructed of any suitable material. The end walls 2 and 3 of the container are concaved and are each provided with a central circular aperture 4. A supplemental end wall 5 is provided for each end of the cylindrical container and comprises a conveXed circular disk having an annular flange 6 adapted to fit over the edge of each end of the clyinder 1. This flange 6 may be bolted or secured to the cylinder 1 in any preferred manner. The end disks 5 are also provided with central openings 7 in longitudinal alineinent with the openings 4 in the ends of the cylinder. Arranged at each end of the container and mounted in the openings 4 and 7 is a stud shaft 8 havinga head 9 formed on its inner end for preventing the displacement of the shaft. The outer end of the stud shaft 8 extends beyond the apex of the convexed disk 5 and is extended through an opening formed in the supporting frame 10 which comprises channel ironsarranged on each side of the conveyer. The ends of the stud shafts 8 are provided with nuts 11 whereby the same may be fastened in engagement with the frame 10.

Encircling the outside of the cylindrical container 1 is a pair of treads 12, one of which is disposed at each end of the container and is employed to perform the Same function as the tread of an ordinary wheel.

A draw bar 13 is attached to the forward end of the frame 10 and a team of horses may be attached to the draw bar for pulling the conveyer over the ground. Disposed rearwardly of the draw bar and directly in front of the container is a seat 14 upon which the driver may be seated when the draft animals are being guided.

Pivotally mounted on the frame 10 and directly in front of the cylindrical container is a comparatively long lever 15 pivotally mounted on the pivot pin 16 carried by the frame. The extreme lower end of the lever is provided with a pintle 17 upon which a wheel 18 is mounted. Extending rearwardly over the lever 15 from a point above the wheel 18 is a brake rod 19 carrying the brake shoe 20 which is disposed in a posltion whereby it may be made to engage and disengage the periphery of one of the annular treads 12. A toothed segment 21 is mounted upon the frame 10 and is adapted to receive the end of a locking bolt carried by the upper end of the lever 15 whereby the lever may be locked in any desired position. This structure provides an effective brake for the conveyer when the same is traveling down an incline surface and Fig. 1 shows the brake in applied position. Normally, the brake will be disengaged from the tread 12 and this is accomplished by releasing the looking bolt from engagement with the segment 21 and applying a rearward pull on the upper end of the lever 15 thereby swinging the wheel 18 free from gaging the brake shoe 20. In applying the the ground and d1senbrake, the reverse operation is performed and it will be noted that the wheel 18 is disposed rearwardly of the pivot pin 16 and the lever is disposed at an angle to the draw bar thereby causing the brake shoe to be forced into engagement with the tread 12.

An opening 22 is provided in the containe whereby the material may be loaded within the container and the sliding door 23 is provided for closing the opening 22.

From the foregoing it will be observed that a very simple and durable conveyer has been provided, the details of which embody the preferred form. I desire it to be understood however, that slight changes in the minor details of construction may be made without departing from the spirit of the invention or the scope of the claim hereunto appended.

I claim:

A. brake of the class described comprising, in combination a rotatable cylinder having annula treads provided on its annular wall,

a frame supported by the cylinder, a brake lever pivotally mounted on the frame and adapted to be moved into and out of engage ment with one of the treads, a toothed segment mounted on the frame, the said brake being provided with a latch adapted to be locked between the teeth of said segment, the said brake shoe being connected to the said lever by a brake arm disposed laterally and extending rcarwardly toward the said treads, the said lever being extended down- \vardly below the said brake arm and carry ing a comparatively small wheel adapted to be moved into engagement with the ground surface for holding the brake shoe in engageuieut with the treads.

' In testimony whereof I aflix my signature in presence of two witnesses.

ANDRE? H. MERRITT.
