J. A. BRILL. BRAKE'ROD HANDLE;

No. 351,735. Patented Nov. 2, 1886.

UNITED STATES I PATENT OFFICE.

JoHN A. BRILL, or PHILADELPHIA, PENNSYLVANIA.

BRAKE-ROD HANDLE.-

SPECIFICATION forming part of Letters Patent No. 351,735, dated November 2, 1886.

Application filed September 17, 1886. Serial No. 213,804. (No model.) I

To all whom it may concern:

Beit known that I, J oHN A. BRILL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Brake-Rod Handles, of which the following is a specification, reference being had therein to the accompanying drawings, whereinrod and of the handle or wheel therefor embodying my improvements. Fig. 2 is a vertical section, partly in elevation, showing engagement of clutch-wheels when'the handle is turned to rotate the brake-rod. Fig.3 is a like view showing position of loose clutchwheel when handle is reversely turned orrotated without turning the brake-rod; andFig. 4 is a section on line 1 1, Fig. 2.

My invention has relation to street-car brakerod handles or wheels of the form wherein the handle when turned in one direction rotates the brake-rod, and when turned in an opposite direction moves independent of or without turning the brake-rod; audit has for its object to provide asimple, economical, and durable form of clutch-wheel mechanism between or connecting the handle and brake-rod.

My invention accordingly consists of the o combination, construction, and arrangement of parts, as hereinafter described and claimed,

having reference particularly to a brake-rod having fixed to it near its upper end a clutchwheel', to which the handle is swiveled the up- I per end of the brake-rod being journaled, or

has a bearing in'the handle, and has loosely mounted on it, so as to slide up and down, a clutch-wheel having a spring-pressure for causing it to normally engage with the clutch- 0 wheel fixed to the brake-rod, and having also side lugs which fit into vertical recesses in the handle, to engage the loose clutch-wheel with the handle and cause them to turn together as the handle is rotated in either direction.

4 In the drawings, A represents a brake-rod for street or other cars, having a reduced upper end, a. Below the latter is firmly secured to rod A, in any suitable manner, a clutchwheel, B, and beneath the wheel B is a collar or platform, 0. The wheel B and collar 0 may be separate and correspondingly secured Figure l is an elevation of part of the brake to rod A, or they may be integral. The'handle D is provided with a lower or bottom socket or hollow hub, d, the edged of which rests upon the collar 0. The handle-socket d is formed with inside oppositely-located vertical recesses or slots, d, and with preferably outside lugs or fillet-pieces, d through which pass pins or screws d, one on each side of the socket d. These pins engage with an annular peripheral groove, b, formed on clutch-wheel B, to swivel the handle or" its socket d to said wheel. Two pins, d", are provided for swiveling the handle to the clutch-wheel B, to make a strong connection between said parts, and to avoid lateral strain between the handleand its swivel connection when the brakes are applied.

Above the fixed clutch-wheel B, and loosely mounted upon the reduced end a of rod A is a second clutch-wheel, E, the teeth 6 orwhich normally engage with the teeth I) of wheel B. This normal engagement is maintained by the pressure or action of a spiral spring, F, surrounding end a, and having one of its ends abutting against wheel E, and the 7 5 other against a shoulder, g, of a socket or re cess, G, in the handle D, above socket d. The upper extremity of the end a of rod A has a bearing, h, in the handleD, to give firmness or support to the handle.

The loose clutch-wheel E has oppositely-located side or peripheral lugs,e,which enter the slots or recesses d in socket d to engage said wheel with socket (I, so that the handle D cannot turn in any direction without rotating the loose clutch-wheel E.

The operation is as follows: When the handle is turned from right to left, the loose clutchwheel E engages with the clutch-wheel B, fixed to rod A, and the latter is rotated to apply the brakes. When thehandleis reversely rotated, the wheel E moving therewith, and being loose on shaft or end a, its teeth ride up on those of wheel B and raise the wheel E out of engagement with wheel B, as shown in Fig. 3, to 5 admit of turning the handle in said last-named direction without rotating the brake-rod.

The bearing h of the end a of rod A in handle D may be of any desired length conformable to the shape of the handle, and any suit- 10o able form of teeth for the clutch-wheel may be employed.

lVhat I claim is-- 1. A brake-rod having near its upper end a collar, a fixed ratchet-wheel of a diameter less than that of the collar, a loose ratchet-wheel of a diameter corresponding with that of the fixed ratchet, a downwardly-acting spring for the loose ratchet-wheel, and a handle or wheel having a socket inelosing said ratchet-wheels and spring, a shoulder for the upper end of the spring to abut or act against, and a swiveled connection with said collar, substantially as set iorth.

2. A brake-rod having a clutch-wheel, B, and collar 0, a handle having socket d resting upon collar 0 and swiveled to wheel B, and a clutch-wheel, E, loose on the brake-rod and turning with the handle, substantially as set forth.

3. The combination of brake-rod A, having elutchavheel B, provided with groove b,ch1tcl1- wheel E, loose on said rod and having springpressure devices, handle D, having socket d, swiveled to wheel B by means of pins (1* entering clutch-wheel groove b, and devices for loosely connecting wheel E with handle D, substantially as set forth.

4. The handle D,having bearing h, recess (1, and socket d, provided with vertical recesses cl, in combination with rod A, having clutchwheel B, swiveled to socket d, loose clutchwheel E, having lugs e, fitting recesses d, and spring F, substantially as set forth.

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

JOHN A BRILL.
