WILLIAM J. STEPHENSON, OF EDNA, KANSAS.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 568,633, dated September 29, 1896.

Application filed January 24,1896. Serial No. 576,716. (No model.)

To all whom, it may concern:

Be it known thatI, WILLIAM J. STEPHEN- SON, of Edna, in the county of Labette and .State of Kansas, have invented certain new and useful Improvements in Wagon-Brakes and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

This invention has reference to wagonbrakes, and the object thereof is to provide improved mechanisms for setting and releasing the brake both when the wagon-body is on and'off.

A further object is to provide an improved brake-lever and brake-shoe mechanism.

The invention consists in the novel features of construction hereinafter fully described and claimed, and illustrated by the accompanying drawings, in which Figure 1 is a side elevation of a wagon carrying a body or box provided with my improved brake. Fig. 2 is a plan view of the rear portion of the wagon-gear. Fig. 3 is a side elevation of the brake mechanism with" the wagon-body removed. Fig. 4 is a similar View with the brake released'from the wheel. Fig. 5 is a vertical cross-sectional 'view on the line of Fig. 2, looking toward the front end of the wagon. Fig. -6 is an enlarged detail view of the brake-operating lever and releasing device carried by the wagon-body. Fig. 7 is a cross-sectional view'of a portion of the body, showing the foot-trip or releasing device. Fig. 8 illustrates in detail the brake lock and holder. Fig. 9 is a cross-sectional view of the parts shown in Fig. 8 when united. Fig. 10 is a detail perspective view of the operating-lever on the rear of the wagon and mechanism supported thereby.

A designates the rear running-gear, and secured transversely on the forward portion thereof is the bar B, carrying at its ends the depending elongated loops B.

O are the brake-levers extended through loops B and pivotally secured to the under side of bar B. To the outer end of each lever G is secured the sectional support D, one portion thereof being secured to the brake-lever by bolt D, as shown in Fig. 9, while the other section of the holder is adjustable thereon, the securing-bolt D extending through the horizontal slot formed therein, as is also shown in said figure. A shoe-holder E is mounted in the adjustable holder D by bolt E, the lower side of holderD resting on lug e of holder D. Flanged lug e on the forward face of holderD secures the wedge-shaped brake-blocks F, which may be renewed from time to time, as desired. Owing to the construction shown, it is impossible for the block F to work downward and out of place. If desired, block F maybe dispensed with and holder E caused tobear directly against the wheel.

Arranged transversely on the rear portion of the running-gear is the bar or support G, and mounted in bearings thereon is shaft H, and formed on one end of the shaft is crank H, while on the other end, mounted between its ends, is lever I, and the lower extremity of crank H and I are connected to the respective brake-levers B by rods J Thus it will be observed that a forward movement of lever I will set the brake. For operating the same with the body in position, as shown in Fig. 1, a rod K extends forward from the upper end of lever I, the connection of the said rod with the lever holding aratchet mechanism carried by the said lever out of gear, and the purpose of this ratchet mechanism will be presently explained.

Rod K at its forward end is connected to bar K, notched upon its under edge, as shown. Secured permanently to the body is dog L, over which bar K is moved forward and which prevents the bar from moving backward until released. Hand-lever M is fulcrumed at its lower end to the body and extends upward inside of the guide Z, and is connected to bar K for the purpose of drawing it forward and setting the brake by rod m. For releasing bar K from the dog L, I provide the vertically-swinging trip N, arranged beneath and in line with said bar and afford it necessary movement through the medium of link at. Trip N is raised to throw bar K from engagement with the dog by rod 0, which secures the proper connection with the trip through slot 0' in lever M and which at its upper end is connected to the small hand-lever O at the top of lever M. Thus with one hand the brake may be set and released with ease. An angular foottrip I projects from the inner side of the body beneath bar K, which may be used for readily releasing the brake by pressure of the foot, the mechanism being clearly shown in Fig. 7. Guide or guardlis made in sections, and the rear portion thereof is adapted to swing upward on pivot Z, so as to permit the hand-lever mechanism to be turned down on the outer side of the body when not in use, and thus entirely out of the way, as shown in dotted lines in Fig. 1.

For operating the brake when the body is removed the ratchet mechanism, held out of operative position, as heretofore stated, is released by the disconnection of rod K and permitted to assume the operative position indicated in Figs. 3 and t. This mechanism consists of a dog Q, carried by the lever I, adapted to engage ratchet Q, secured to bar 13. The dog is controlled by red R, which at its upper end is connected to the angle-lever R, the function of this last-named lever being to hold the dog raised and out of engagement with the ratchet when the operating mechanism carried by the wagon-body is used. The upper end of lever I carries on its forward side a ring or loop I, through which depends an operating-bar S. The lower end of this bar projects through the elongated ring S, surrounding lover I and secured at its rear side to rod R and provided between its ends with a transverse bar .9. This transverse bar extends through diagonal slot 1' in lover I, so that by a backward push upon bar S the lower end will be thrown forward, thus pulling forward link S and causing it to be raised through the medium of bar 3, traveling in the diagonal slot, thereby raising and disengaging dog Q from ratchet Q and releasing the brake. A forward pull upon the upper end of bar S will simply draw forward lover I, which is firmly held by the dog, as will be readily understood.

Thus a most simple and eifective brake mechanism is provided which may be operated as well when the wagon is in use with its body as when used without it. It may be stated that bar S is provided and arranged as shown for convenience in operating the brake when loads of lumber or other material are piled high upon the wagon, so as to render lover I quite out of rcaeh. It will be understood, however, that the said bar may be dispensed with and the brake set and released by the driver through the medium of the angular lever R, as will be understood.

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

1. The combination of asupporthavingoutwardly-extending parallel members, lugs c at the lower ends of said members, a brakeshoe holder having projecting parallel members adapted to overlap and be pivotally secured to the support members, the lugs a eugaging and limiting the downward movement of the shoe-holder, and a brake-shoe adapted to be secured to the holder, substantially as shown and described.

2. The combination of support I) having outwardly-extendin g vertically-disposcd parallel members formed with alined openings, lugs e at the lower ends of the support members, a shoe-holder having outwardly-extending vertically-disposed parallel members adapted to overlap the support members and formed with openings alining with the openings of the support members, a pivotal bolt extended through the said openings and uniting the support and holder, and a brake-block adapted to be secured to the holder, substantially as shown and described.

3.

7. I11 a brake mechanism, the wheel-engaging devices, the forwardly-movable notched bar for actuating the same, the permanent dog over which the bar moves to prevent backward movement of the latter, the hand-lever connected to the said bar for operating it, the trip arranged beneath the bar and provided with the link connection, the rod for raising the trip, and the small hand-lever carried by the first-named lever to which the said rod is connected, substantially as shown and described.
