VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 537,100,,dated April 9, 1895. Application filed March 27, 1894. Renewed February 18, 1896. $erial No. 538,885 (No model.)

To aZZ whom it may concern:

Be it known that I, FREDERICK A. YOUNG, of Richmond, Ray county,'Missouri, have invented certain new and useful Improvements in Vehicle-Brakes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. I

My invention relates, to vehicle brakes, and has for its object to produce a brake mechanism which is simple, strong and durable; which is positive and reliable in action, and which may be operated from various points; furthermore, to produce a mechanism of this character which may be easily secured in or removed from position, and which is inexpensive of construction.

With these objects in view, the invention consists in certain peculiar and novel features of construction and combination of parts, as hereinafter described and claimed.

In order that the invention may by fully understood, reference isto be had to the, accompanying drawings, in .which Figure 1. is a vertical longitudinal section of a wagon, and showing my improved mechanism applied thereto in operative position. Fig. 2. is a side elevation of my improved brake-mechanism, and showing it operatively applied to a wagon, and showing it connected with a hand lever of difierent construction from that shown in Fig. 1. Fig. 3. is a perspective view of the brake-mechanism in operative position. Fig. 4. isadetail view. Fig. 5. is a view. of my improved brake-mechanism, as applied to ahay-rack, Fig. 6. is a detail perspective view of a construction slightly difierent from that shown in Fig. 3, and Figs. 7, 8, and 9, are detail views of variousparts.

In the said drawings, 1 designates the rear Wheels of a wagon truck, and 2 designates the axle connecting the same.

3 designates the front wheels, 4 the axle connecting the same, and 5 the longitudinally extending reach which connects the front and rear axles in. the ordinary manner.

6 designates the hounds, converging forwardly from the rear axle and secured to opposite sidesof the reach in the ordinary manner, andbolted or otherwise rigidly secured upon said hounds, is a semicircular casting 7, the open side of which is disposed forwardly, and is secured in anysuitablemannor to the transversely extending bar 8. This bar rests upon the upper side of the hounds and the reach, and is secured firmly in this position by the U-shaped clips 8, which em brace the hounds at their lower and opposite sides, and projecting up through the said transverse bar, have their screw-threaded ends engaged by retaining-nuts 8". It is' to be understood, however, that this bar may be secured rigidly upon the hounds and reach in any other suitable manner without departing from the spirit of my invention. A rock-shaft 9, is journaled longitudinally of and upon the bar 8, and is provided at each end with the depending arms 10, terminating in books, which pivotally engage the staples or loops 11, projecting upwardly from thebrake-beam 12, which is arranged a suitable distance in advance of the front peripheries of the rear wheels, and carries at each end the brakeshoes 13, in the ordinary manner. Arranged longitudinally of and vertically beneath the center of the reach-bar 5, is a semicircular casting 14, which depends from and has its ends rigidly secured to the semicircular casting 7, and the under side of the cross-bar 8. A lever, which operates in a vertical plane, is pivoted at 15 to the said casting 14, and is composed of similar arms 16, extending diverg'ently upward from the pivotal point 15 so as to embrace loosely the opposite sides of the reach-bar 5, and the upper ends of these arms are connected by the bolt 17, and the lower ends by the bolt 18. A link-bar 19' is pivotally mounted at one end upon said bolt 18, and is secured at its opposite end to the brakebeam, about midway its length. A longitudinally extending bar 19, is pivotally connected at its rear end upon the bolt 17, and projecting forwardly therefrom, extends beneath the guide-loop 20, projecting upwardly from the cross-bar 8.

It will be apparent from the foregoing, that the forward movement of the bar 19, will rock the lever composed of the similar arms 16,

and cause the brake-shoes to engage the periphery of the rear wheels. Depending from, and extending longitudinally of the bar 19, is a loop 21, and extending transversely of the machine and through said loop, is a lever 22, which is pivoted at 23 to the semicircular casting 7, adjacent to one end. It will be apparent from this construction, that the operation of thelever22, in thedirection of the arrow, Fig. 3, will move the bar 19 forwardly, and apply the brakes as above explained.

The casting 24 is bolted upon the upper side of the bar 19, and is formed with a recess 25 in its rear end; said recess being the equivalent of the loop 21, and engaging this recess, and extending transversely of the wagon, is a lever 26, the free or handle end of which projects slightly beyond the side of the wagon, and this lever is pivotally connected at 27 to the semicircular casting 7, and adjacent to one end thereof. By the operation of this lever in the direction of the arrow, Fig. 6, it will be apparent that the bar 19'is moved as above explained, and the brakes applied, and in order to secure the brakes against the wheels, the casting 7 is provided with the toothed segment 28, which is engaged by the lever 26; said lever being of spring-metal, so that it shall hold its position when once in engagement with this toothed segment.

In Fig. 1, 29 designates a vertical shaft, which is mounted at the front end of the wagon'body, and this shaft carries, at its lower end, a cog-wheel 30, which meshes with the teeth of a rack-bar 31, which is pivotally connected at 32 at its rear end, to the front end of the longitudinally extending bar 19, and this rack-bar is supported in operative position at its front end and held in engagement with the co -wheel 30 by a guide'casting 33, which is secured to the bottom of the wagon. 34E designates a lever, which is pivoted to operate in a vertical plane, to the upper end of the shaft 29, and this lever engages the racksegment 35, secured to the foot-board of the wagon. The lever 34, is preferably in the form of a crank-handle, so that by operating it in one direction or the other, the brake may be applied or thrown from its engagement with the wheels.

In Fig. 2, 36 designates alever, which is pivoted at the side of the wagon, and engages the rack-segment 37, in the usual manner, and this lever 36, is connected through the medium of the link-bar 38, with the free end of the transversely extending lever 22, so that by the operation of the lever 36, the brakemechanism may be operated as required.

In Fig. 5, a hay-rack is shown mounted operatively upon the truck, and the lever 39, pivotally mounted at the front end of the hayrack, is pivotally connected through the medium of the link-rod 40, to the front end of the longitudinally extending bar 19, so that bythe operation of the lever 19 the brake-shoes may be thrown into or out of engagement with the rear wheels.

In the practical construction of this brakemechanism, either one or another of the three means of operating the brakemechanism from the front end of the wagon, will be employed in connection with the laterally extending lever 26'; said lever being provided for use when occasion may demand, such, for instance, as when the wagon is upon a descend ing plane, and the person in charge is walking at one side. of the wagon, when he may apply the brake without remountin From the above description, it will be apparent, that I have produced a brake-mechanism which may be applied to any of the ordinary forms of wagons now in use easily and expeditiously; which is positive and reliable in operation; which may be operated from various points, and which is simple, durable, and inexpensive of construction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
