GiElORGrlE4 W. FISHER, OF UPPERCO, IVIARYLAND, ASS'IGNOR OF ONE-HALF TO L. C. CALTRIDER, OF UPPERCO, MARYLAND.

VEHICLE- Serial No.

T o all whom it may concern:

Be it known that I, GEORGE XV. FISHER, a citizen of the United States, residing at Upperco, in the county of Baltimore and State of Maryland, have invented a new and useful Vehicle-Brake, of which the following is the specification.

My invention relates to improvements in automatic brakes for vehicles, and the object thereof is to improve and simplify the construction over the existing prior state of the art; and the invention consists in the novel construction and combination of parts as will be hereinafter more in detail described and the asserted novelty specifically claimed.

I have fully and clearly illustrated my invention in the accompanying` drawings, in which,

y Figure l represents a top or plan view of my invention to wh ich my improvements are applied. Fig. 2 represents a longitudinal side elevation of the same, and Figs. 3 and 4 are also plan views thereof.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings: A, A designate the forward wheels and B, B the rear wheels of a. wagon mounted upon the forward and rear axles C and C respectively in the ordinary manner. l

D designates the reach or connecting bar connecting the forward and rear axles together, opening c being formed centrally between the bolster and forward axle C and through which said reach is projected, the reach D and also the bolster of the forward axle C being provided with a perforation (l for the reception of the usual king bolt CZ for the turning thereon of the forward axle, bolster and reach of the wagon.

E, E designate the hounds of the forward axle which are passed transversely through the opening, between the bolster and the forward axle C and in which they are held at this point, the forward ends of said hounds being provided with a slotted clip Elv through which a tongue E2 is passed and secured within the clip by means of a screw e passed through perforations c, e2 formed in said clip and the rear end of the tongue.v a tongue cap being secured to the forward end of the tongue to admit of the engagement of a chain E3 and twin hooks F, F, the latter being pivotally secured to this end of BRAKE.

the tongue, as more clearly shown in Fig. 2 of the drawings.

G designates the frame work of the brake operating mechanism of the wagon composed of side and end bars g', g2 and g and an inner bar g4 located parallel with the side bars g and g3 and to these bars g3 and g4 aretransversely secured short bars g5 and 96 which serve as a support for a number of toggle jointed levers 7i, 7L, k2, h3 which are pivotally secured near their ends to said bars g5 and 9G the ends of said levers h, h3 engaging parallel slots 71,4, h5 formed in and near the forward end of a bar z' secured centrally and at right angles to a brake shoe bar J having brake shoes J J 2 secured to its ends.

K, K designate short pins having their ends secured in the side bar g and the inner parallel bar g4E near the ends of said bars on which spiral springs K', K2 loosely play backwardly and forwardly, these pins being also passed through perforations in the brake shoe bar for a purpose which will hereinf after more fully appear.

L, L designate the rear hounds, the rear ends of which are secured and passed between the rear axle C and bolster of the wagon, the forward ends of the hounds converging to the reach D and secured within the slotted clip N.

O, O designate eye-bolts secured to the rear axle C in any suitable manner. Through these eye-bolts O, O is transversely passed a roller P for side locking the wagon.

Q designates a hand lever pivotally se cured to the rear axle C through the medium of an eye-bolt plate R, this lever having at its pivotal end a right angular bifurcated projection formed integral therewith having perforation therein through which a pivot is passed pivotally connecting the right angular bifurcated projection with the slot in the bar I.

S designates a lug secured midway the length of the roller P having an eye p therein through which is passed a pin Q for the purpose of connecting thereto a hook Q bifurcated at its rear end, the lug S being passed into this bifurcation. The free end of this hook engages the central slot in the bar I heretofore described. To one end of the roller P is detachably secured a hand-lever T by means of which through the medium of the roller P the hook g is manipulated for operating the bar Iv independently of the automatically disposed drawbar to be hereinafter described.

U designates a longitudinally centrally loj cated and automatically operated adjustable slotted draw-bar, the rear end of which is pivotally secured to the forward ends of the toggle jointed levers h, h2 connecting with the levers 7a and 7b3 of the hand oper"- ated bar l. This draw-bar U is made in sections U, U', the ends of which are slidably passed through loops V, V", overlapped M72 designates `a bolsterplate vrigidly secured tothe top of the .bolsterand `provided centrally with a 4perforation d which is inv alinement with the perforation in the bolster hereinafter described, :and as previously stated, vis for the xreception of thefking bolt. This king Abolt d l.engages ,the slot in the rear end of the angular .portion or section of the draw-bar. The lower angle of this angular -section terminates in a rod portion w. x A

X designates a slotted eye-bolt secured to `the under side of the tongue through which the rod portion w is passed, and which serves Yas a guide Yfor said rod. This rod or rod portion of the draw-,bar is bifuroated atits extreme outer and forward end, and pivota-lly connected therewith are the twin hooks F F by means of Ia pivot ,pin X2 which is passed /throuofh alined perforations both in the bifurcateend of therod and also in alined perforations in the said hooks.

Ydesignates a coiled spring, one end of which is secured to the slotted eye-bolt, its opposite end being looped and through which is also passed the pivot X2 thus 'connecting said spring with the bifurcation in the rod portion of the draw-bar and Athe levers F F.

Z designates a ratchet sector having its ends secu-red to the ends of the rear hounds.

Z designates a brace hav-ing one end secured to the rear axle C and its opposite :end secured centrally to the ratchet sector.

rZ2 designates la short blade secured to the underside of the lever which engages the ratchet sect-.or by means :of which the bar I and its mechanism is operated.

From the foregoing construction herein shown and described it will be obvious that my device .can be o perated from three different positions. Two motions are given to leased .from `the wheels.

By .means of the twin hooks `detachably secured to the forward end of the tongue and lthe tongue chains secured to the vtongue vcaplI-am enabled by this means Ito back any load anywhere and under any circumstances, and further by the use of this means after backing up a load the twin hooks .regain their normal position. p K I By adjusting the draw-bar which is made in .two .parts overlapping each other Athe wagon gear can be shortened or lengthened at pleasure. Then two horses are controlled there can be eight tons hauled down agrade as easily as four tons.

Mybrake is strong and durable in its construction and in case of a runaway by the horses the stopping of the horses can be easily controlled. y

Having th-us 'described my invention what l c-laim as new and desire --to secure by Letters Patent is 1- y l.
