GEORGE W. WISE, OF WARNER'LAKE, OREGON.

VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 531,672, dated January 1, 1895. Application filed April 28, 1894. Serial No. 509,370. (No model.)

Be it known that I, GEORGE W. WISE, of Warner Lake, in the county of Lake and State of Oregon, have invented certain new and useful Improvements in Vehicle-Brakes, and v I do hereby declare the following to be a full, clear, and exact description of the invention such as willenable others skilled in the art to which it appertains to make and use the same.

My inevntion relates to an improvement in vehicle-brakes, the object being to provide a device so constructed that the introduction of new brake-shoes or blocks can be quickly and easily accomplished. V

A further obj eot is in the adjustable feature of the motel frame, whereby different thicknesses of brake-shoes or blocks are accommodated. 7

With these ends in view my invention consists in certain novel features of construction and combinations of parts as will be hereinafter more fully described and pointed out in the claims. g

In the accompanying drawings, Figure 1 is a sectional View of myimprovement. Fig. 2 is a detached view of the metal frame.

A represents the brake-block, which is rigidly secured to the beam B in any desired manner.

The brakeblock A is preferably con: structed of wood and is adapted to support the adjustable metal frame 0, which in turn is designed to assist in retaining the brakeshoes or blocks in their normal oroperative position as will be hereinafter set forth.

The metal frame 0 is composed of sides a, a, and ends a 0. The outer edges of sides a, a, are flanged as shown at b or in other words bent at right angles to the remaining By thus flanging the sides a, a,a groove or channel is formed, whereby the brake-shoes or blocks are retained in their operative position. End a of the frame A isintegral with the sides thereof and is cut away as shown at b, said cut-away portion being adapted to allow of the ready removal of worn out or damaged brake-shoes. The opposite or lower end of vframe A is hinged to one side of said frame asat 0, while its opposite end is provided with an ordinary hasp d, through the medium of which end a is locked against displacement when in its operative or closed position. The lockingof said hasp is" accomplished by means of staple f and pin g, as shown in the drawings. End a. is slightly cut away as shown at h, which admits of a due wearing away of the brakeshoes or blocks without coming in contact or in any manner damaging the end. While end a is cut away sufliciently to prevent injury to its outer edge, yet it is not cut-away enough to allow any of the brake-shoes or blocks to escape from the groove, but its position on the brake-block is such that it acts as an abutment or stop against which the first shoe rests and it also performs the important function of retaining theentire series of shoes inposition within the groove.

From the foregoing it will be seen that worn out or damaged brake-shoes or blocks. may be removed from the groove, either from the top or bottom, but in practice I prefer to insert the brakeshoes from the top and remove them from the bottom, for the reason that their own weight will cause them to assume the desired position, without any manual interference.

Integral with the sides a, a',of frameC and projecting rearwardly therefrom, are arms It, and I0 10 the former being adapted to rest block. Bolts 'n are adapted to pass through said slots land holes m and retain the metal frame in an adjustable position on the brakeblock.

The brake-shoes or blocks D are preferably constructed of wood and are of such form and construction as to enable them to be inserted'and retained within the groove above referred to.

When it is desired to increase the thickness of the brake-shoes or blocks, it is simplynecessary to loosen thenuts on bolts n,'move-the frame 0 the desired distance, after which the nuts on bolts 1:. are tightened and the arms thus'locked against movement. The groove or channel formed bythe overlapping edges b and the brake block A, is then ready to receive and retain the new brake-shoes.

It is evident that changes in the construction and relative arrangement of the several parts might be made without avoiding my invention and hence I would have'it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but,

Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In a vehicle-brake, the combination with a brake-block, of a metallic frame having overlapping side edges, rearwardly projecting arms integral with said frame, and means for securing said frame adj ustably to the brakeblock, substantially as set forth.

2. In a vehicle-brake, the combination with a brake-block having holes located therein, of a metal frame provided with overlapping side edges and rearwardly projecting arms, said arms having slots located therein, which latter are adapted to register with the holes in the brake-block and means for adj nstably locking said frame to the brake-blocks, substantially as set forth.

3. In a vehicle brake, the combination with a brake-block having holes located therein, of a metal frame composed of sides having overlapping edges, and ends, one of which is integral with the sides of said frame, while the other is hinged to one side and adapted to be locked to the opposite side by any suitable means, and rearward] y projecting arms, which latter are provided with slots which register with the holes located in the brake-block, and means for adjnstably locking the frame to the brake-block, substantially as and for the purpose described.

4. In a vehicle brake, the combination with a brake block, of a skeleton frame constructed to form a groove or channel between itself and the block to receive removable brake shoes, and a lower end for the support of these shoes, said lower end removable independently of the skeleton frame,substantially as set forth. it

5. The combination with a brake block having a groove or channel, in its forward edge adapted to receive and hold removable brake shoes, of a bottom for the support of said shoes removable independently of the brake block, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

GEORGE W; WISE.
