VILLIAM E. STEVENS, OF SOUTHVEST OSVEGO, NEW YORK.

VEHlCLE-BRAKE.,

SPECIFICATION forming part of Letters Patent No. 432,775, dated J' uly 22, 1890.

Application filed May 15, 1890. Serial No. 351,900. (No model.)4

To coZZ whom it may concern:

Be it known that I, WILLIAM E. STnvENs, of Southwest Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvemcnts in Vehicle- Brakes, of which the following, taken in connection with the aceompanying drawings, is a full, clear, and exact description.

My invention relates to Vehicles, and especially to those which are provided with an adjustablc spring-pole support and with Vbrakes which are operated by the horses through devices connected to the pole to which the n eekyoke is directly connected.

My object is to improve the construction of the vehicle in these respects, thereby increasin g its utility and convenienee.

My invention consists in the several novel features of construction and operation hereinafter described, and specifieally set forth in the claim annexed.

It is eonstructed as follows, reference being had to the accompanying drawings, in which- Figure 1 is a top plan view of the front Wheels, hounds, and pole of a wagon with my improvements attached. Fig. 2 is a like view of the pole-supporting spring, part of the pole, and part of the axle. Fig. isa side elevation of the construction shown in Fig. 2. Fig. 4 is a side elevation of the front end of the pole. Fig. '5 is a side elevation showing the connection of the brake-beam to the hounds and the Springs holding` the beam away from the Wheel. Fig. 6 is .a plan view of the brake-shoe holder upon each end of the brake-beam. Fig. 7 is a front elevation thereof. Fig. 8 is an enlarged side elevation of the brake-shoe, its holder, and of the end of the brake-beam.

Ais the hounds, carried by the axle 1 and Wheels 2, and 3 is the pole connected to the front end of the hounds upon a cross-bolt, as I cut a mortise t in the front end of the pole, in which l pivot a hook-shaped crank-lever 5, the hook being adapted to re-' ceive the ring G of the neek-yoke, and the lower end 7 of this lever is pivotally connected to the back rod 8, which is carried back under the pole, where it is connected to the bifurcated bars 9, which extend back through and are secured to the brake-beam 10. Upon the ends of this beam I secure my brake-shoe holder 11, provided upon its outer end with a slideway 12, disposed aty an angle to the body of the holder, as shown in Fig. 6; and 13 is a trangular frame having one side provided with outward fianges, so that it fits freely in the slide, and having another side adapted to carry the bralce-shoe 14 by the bolt-and-stud connection shown in Fig. 8 by the dotted lines; and 15 is a coiled spring secured to the brake-beam on either side of the frame and looped around the bottom thereof,

'so that when the wheels are rotated forward and l(he horses are holding' back the brakebeam Willbe drawn toward the wheel, the friction will slide the frames upward in the slides, and the shoes Will bite firmly against them; but when the Wheels are rotated back- Ward, although the brake-beam is then drawn toward them, the friction of the Wheels upon the shoes Will be reversed, which Will draw the frame's down iu the slides, throwing the shoes away from the Wheels and preventing them from biting against them, so that the brake Will not become set When the team is hacking the vehicle.

Futchells 16 are secured to pole in the usual manner, and are braced thereto by cross-rods, as shown, and they are also perforated Vertieally adjacent to their rear ends to receive bolts 17, provided with hooks 18 upon their lower ends, the upper ends being threaded.

B is my pole-supporting spring, of substantially U or V form, the rear ends fitting nnder the axle, the hooks fitting around them in front of the axle, the front being provided with a cross-piece, upon Which the pole rests, and ears or other means to hold the pole in position upon the spring. The elevation of the outer end of the pole can be regulated by tightening or loosening the nu ts on the hookbolts, and the spring has its fulcral bearing upon the hooks and axle.V

'Vhat I claim. as my invention, and desire to secure by Letters Patent, is-

The combination, with the brake beam connected by a draw and level' bar to the front end of the pole, of :L brake-shoe holder seeured upon 'each end of Jche brake-beam, a slide on each holder, a frame fifiting in said 5 slide, a brake-shoe seeured to the frame, and

a spring conneeting the frame tO the brakebeam.
