LOCK FOR WAGON-BRAKES.

PEGIFICATIQN forming part of lietters Patent No. 342,121, dated May 18, 1886.

Application filed April 3, 1886. Serial No. 197,616. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM MOORE, of Mooney, in the county of Jackson and State of Indiana,have invented anew and Improved Lock for Wagon-Brakes, of which the following-is a full, clear, and exact description.

My invention relates to the construction of an improved form of brake-operating mechanism adapted for connection to the brakelever and arranged to be secured to the outer side of the wagon-body, the object of the invention being to increase the throw of the brakeshoe from the wheel, thus moving the shoe to a position where it will not be liable to collect mud.

A further object of the invention is to increase the effect of the power applied to the lever as the brake-shoe is thrown against the wheel; and these objects I accomplish by means of a lever mounted on a rack and arranged so as to have two fulcrums that are at unequal distances from the point of connection of the connecting-rod leading to the brake lever, said double-fulcrumed lever carrying a springpressed pawl of novel construction that engages with a double curved rack, the axes of the two curves being at the two fulcrums of the lever.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side view of a wagon-body rep resenting my improved brake-lock as in position for use, the position of the hind wheel of the Wagon being indicated by dotted lines. Fig. 2 is an inverted plan view of the same, and Fig. Sis a sectional elevation taken on line y y of Fig. 1.

In constructing such an apparatus as is illustrated in the drawings above referred to, I provide a frame, A,that is formed or provided with two sockets, a a, and in these sockets I arrange or mount the pins 1) b of a double armed lever, B, each pin resting within its socket when the lever is in about a vertical position, as shown in Fig. 1. Above the sockets I arrange a double-curved rack, 0, formed in two sections, 0 c, the axis of the section 0 corresponding with the axis of the pin b when such pin is seated within its socket a, while the axis of the section 0 corresponds with the axis of thepinb' when suchpin is seated within its socket a.

As seen bestiu Fig. 3, the rack Gstands out some distance from the side of the wagonbody, and the lever B is guided by means of a clamp, d, that projects-from the lever down behind the rack, the lever being also provided with a lug, e, which prevents it from lifting, said lug being arranged to ride beneath the rack.

Just in front of the rack O the single arm of the lever Bis divided into two arms,f f, that are again united above the rack to form asingle arm. The arm f extends somewhat outward beyond the general face-line of the lever, and near'the handle or upper end of the lever there is a bracket, g, in which there is mounted a rod, D, thelower end of which carries a sleeve, h, that engages with the arm f of the lever B, apaw], i, being carried by the lower end of the rod D,which enters the space between the arms f f, and is pressed against the teeth of the rack 'O by a spring, E, the upper end of which is rigidly secured to the lever B. Upon the upper end of the bar D there is a crank-arm, s, having a handle, 3, arranged so that when the handle tis brought toward the handle of the lever the pawl'i will be thrown out of engagement with the rack O.

The lower ends of the two arms a n of the lever B extend somewhat beyond the pivotpins 1) b, and the inner ends of these pivotpins are connected by a strap or rod, Z, which also extends beyond the pivot-points, and as the lever is rocked upon either one of its fulcrums the portions projecting beyond the pivot that is disconnected or moved from its fulcrum will ride upon either side of the guiding-strips 0 o, of which the strip 0 is concentric to the axis of the pivot 11, while the strip 0 is concentric to the axis oF the pivot I), the upper ends of the two strips 0 0 being united and the strips being braced by a cross-bar, m, arranged as best shown in Fig. l. The outer ends of the rack O are held by braces pp, which also serve as supports for the lower ends of the strips 0 0; and it will be understood that although all of the stationary parts described could be made in separate pieces and united, theycould also be made in a single casting, which latter mode I greatly prefer.

The lever B is connected to the upper end 1; but if the roads were muddy the lever would be moved to the position shown in dotted lines in Fig. 1, thus throwing the brake-shoe to a position at quite a distance from the periphery of the wheel.

When it is desired to apply the brakes, the lever B is forced forward in the direction of the arrow shown in connection therewith,and as the connecting-rod approaches the fulcrum of the lever as said lever is being so moved forward,it will be readily understood that the effect of the power increases as the brake shoe approaches the wheel, and it will also be understood that as the lever B is being thrown from a vertical position to the position shown in dotted lines in Fig. 1,as the arm n is longer than the'armn, the brake-shoe P will move more rapidly after the lever becomes fulorn med at c.

Having thus fully described myinvention,

what I claim as new, and desire to secure by Letters Patent, is

1. In a brake-locking mechanism, the combination, with a lever formed with two arms, upon both of which it may be fnlcrumed, of a 0 spring-pressed pawl carried by a rod that is mounted on the lever, substantially as described.

2. In a brake-locking mechanism, the combination, with a lever, B, formed with arms 35 n n and pivot-pins b b,of a frame having sock- 'ets a a and a double-curved rack, 0, substantially as described.

3. In a brake-locking mechanism, the combination, with a lever, B, formed with arms 40 n n and pivot-pins b b, of a frame having sockets a a, a double-curved rack, O, a-rod,

D, carried by the lever and provided with a pawl, i, a spring, E, a connecting-rod, O, and a brake-lever carrying a brake-shoe, substan- 4 tially as described.
