VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 795,144, dated July 18, 1905.

Ap li ati n fil d February 14, 1905. Serial No. 245,600.

To all whom, it may concern:

Be it known that I, CLAYTON H. LONGEN- noxnn, a citizen of the United States, residing at Campbelltown, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Vehicle- 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.

My invention relates to vehicle-brakes; and it consists in certain improvements in construction which will be fully disclosed in the following specification and claim.

In the accompanying drawings, which form part 'of this specification, Figure 1 is an inverted plan view of the rear portion of a vehicle, showing my invention applied; and Fig. 2 apcrspective view of part of the brake mech anism and the rear axle.

Reference being had to the drawings and the designating characters thereon, the numoral 1 indicates the pole or reach of a vehicle; 2, the rear axle provided with wheels 3 3. 1 4 indicate the hounds.

5 indicates a compound lever having arms 6, 7, and 8 and is pivotally secured to the axle 2 by a screw-bolt 9, and to the arm 6 is attached a rod 10, which extends forward and is secured to a lever 11, pivotally attached to the pole 1, by which power is applied to the brakes.

To the arm 7 is pivotally secured a rod 12, which is pivotally secured to one end of a lever 13, and the opposite end of lever 13 is pivotally secured at to the outer end of the brake-lever 16, which is pivotally secured to a plate 17 at 18 and acts as a fulcrum to the brake-lever 16, and to the outer end of lever 16 is attached a brake-shoe 19, concavo-convex in form, and engages the band on the inner end of the hub 21 of the wheel 3.

To the pin 1a is connected a bar 22, which is pivotally connected to the outer end of the brake-lever 23, which is pivotally secured to plate 2 1 at and is provided with a' brake shoe 26 of the same construction as the shoe 19 and engages the hub-band 2O diametrically opposite shoe 19. The plates 17 and 24: extend through and are secured to the axle 2 by a yoke 27 and a clamping-bar 28 and nuts 29 29, which engage the projecting ends 30 of the yoke.

To the arm 8 of the compound lever 5 is pivotally secured a rod 12, which is pivotally secured to one end of a lever 13, and the opposite end of lever 13 is pivotally secured at 15' to the outer end of the brake-lever 16, which is pivotally secured to a plate corresponding with plate 17 at 18 and acts as a fulcrum to the brake-lever 16, and to the outer end of the brake-lever 16 is attached a brake-shoe 19, concavo-convex in form, and engages the band 20 on the inner end of the hub 21 of the wheel 3.

To the pin 14 is connected a bar 22, which is pivotally connected to the outer end of the brake-lever 23, which is pivotally secured to a plate corresponding with plate 24: at 25' and is provided with a brake-shoe 26 of the same construction as the shoe 19 and engages the hub-band 20, diametrically opposite shoe 19.

The brake-levers are secured to the axle by means corresponding with the plates 17 and 24 and are secured to the axle 2 by a like yoke 27 and a clamping-bar 28 and nuts 29' 29', which engage the projecting ends 30 30 of the yoke.

The mechanism on each side of the center of the axle is a duplicate of that on the opposite side, and eachbrake-shoe is provided with a leather lining or rubber 31.

It is obvious that the more power employed to operate the lever 11 the tighter and harder the brake-shoes will grip the sand-bands.

This class of brake is especially adapted to light vehicles, and particularly to rubber-tired vehicles, where one object is to save the wear and tear on the tires and another is to get an even and uniform pressure of the brake on both wheels at the same time, and thereby bring the vehicle to a stop or, at least, reduce its speed. It is also obvious that all ofthe parts of this brake may be made of steel or wrought-iron and can be carried in stock and the parts, when necessary, replaced with little or no trouble.

Having thus fully described my invention, What I claim is A vehicle-brake comprising a triple-armed horizontal lever pivotally secured to the axle, brake-shoes engaging" opposite sides of the hub of the Wheel, levers supporting said brakeshoes and fulcrumed on plates secured to the axle, means for connecting the free ends of said levers, a pivoted connection between said
