ROBERT P. TAYLOR, OF GOLD HILL, NEVADA.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 433,753, dated August 5, 1890.

Application filed May 22, 1390. Serial No. 352,759.

To aZZ whom it may concern.-

Be it known that I,ROBERT P.TAYLOR, a citizen of the United States of America, residing at Gold Hill, in the county of Storey and State of Nevada, have inventedcertain new and useful Improvements in' l/Vagon-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 appertains to make and use the same, referencebeinghad to the accompanyingdrawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in brakes for wagons; and it consists in the construction and combination of the parts, as will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view showing my improvement applied to a wagon-body and brake-lever. Fig. 2 is a plan view.

A refers to the side-board of a wagon, which is provided with a journal a, upon which is mounted a-ratchet-disk B, provided integral therewith on its inner side with a projecting rim having teeth I). This ratchet-wheel is supported wholly by the journal a and is free to rotate thereon.

0 refers to a guard or strap also secured to the side-board A, so that the central portion thereof, which extends over the face of the ratchet-wheel,will be a sufficient distance from said ratchet-wheel to permit the upper end of the brake-operating lever D to lie under the same and adjacent to the face of said wheel. The lower end of the brake-operating lever D is pivoted upon a projection beneath the ratchet-wheel, which extends outwardly and is secured to th e side-board A of the wagon-body. This operating-lever carries a pawl d, which may operate by gravity or be assisted by a spring, and to this lever, at a suitable point between its lower end and the pawl, is a proj ecting pin, to which is secured a bar E, which extends to the upper end of the rock-shaft or brake-bar F, as shown.

The upper edge of the side-board A is notched, as shown at g, to permit the bent end (No model.

of a pivoted dog G to engage the teeth secured on the inner side of the ratchet-wheel. This dog serves as a lock for the disk and willprevent rotation of the same until one end is depressed to throw it out of engagement with the teeth. I

In operation, when it is desired to cause the brake-blocks to contact with the Wheels, it is only necessary to move the lever D to one side, when the pawl will automatically engage with the teeth and hold the brake locked and when it is desired to releasethe brake, the dogG can be depressed to bring it out of engagement with the teeth, when'said disk will be free to rotate.

By providing a device constructed as hereinbefore described, the brake-blocks can be readily brought in contact with the Wheels or held out of engagement therewith. It will be noticed that the brake hereinbefore described is applicable to all kinds of vehicles, is simple in action, and easily constructed.

I am aware that prior to my invention it has been proposed to provide wagon-brakes with ratchet-disks and operating-levers carrying a pawl for rotating the disk; but in such cases the releasing pawl or dog is placed where it is difficult to have access thereto, and the connecting-bar is not attached directly to the lever.

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

1. In a wagon-brake, the combination of a lever, a bar or rod connecting the same with the brake-lever, a rotary disk having ratchetteeth and cogs, a pawl carried by the lever for engagement with the ratchet-teeth, and a dog for engaging with the cogs to lock the ratchet-disk, substantially as shown, and for the purpose set forth.

2. The combination, in a wagon-brake, of a lever D, connecting-rod E, rotary ratchet-disk having laterally-projecting teeth formed integral therewith, a dog for engaging with said laterally-projecting teeth, a pawl carried by the lever D so as to engage the ratchet-teeth of the disk, and a guard or strap 0, substantially as shown, and for the purpose set forth.

3. The combination of a brake-lever D, pivoted at itslower end to awagon-bodyv and p roratchet-disk, the parts being constructed and lo vided with a pawl, a bar connected to said organized substantially as shown, and for the lever between its end and the pawl, adisk purpose set forth.

having ratchet-teeth and laterally-proj eeting In testimony whereof I affix my signature in 5 cogs journaled upon a suitable bearing, adog presence of two witnesses.
