VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 735,253, dated August 4, 1903.

Application filed June 7, 1902. Serial No. 110,685. (No model.)

To all whom it may concern.-

Be it known thatwe, MICHAEL FIERSTINE HARTMAN and' HOMER CLoiD HARTMAN, citizens of the United States, residing at Henrietta, in the county of Blair and State of Pennsylvania, have invented a new and useful Vehicle-Brake, of which the following is a specification.

This invention relates generally to wagonbrakes, and more particularly to a brake mechanism capable of operation either from tion of brake.

the drivers seat or from a lever at the rear end of the wagon-body.

.sists in the novel features of construction,

combination, and arrangement, all of which will be fully described hereinafter and pointed out in the claims. In the drawings, forming part of this specification, Figure l is a side elevation of a wagon provided with our improved construc- Fig. 2 is a top plan View of the running-gear, showing the brake mechanism applied thereto, the operating rod and lever connected to the wagon bodybeing omitted. Fig. 3 is an enlarged top plan View, partly in section, illustrating the manner of operating the brake from the rear end of the running-gear. Fig. 4. is a section on the line 4. 4 of Fig. 3. Fig. 5 is an enlarged view of the operating-lever,certain parts being shown in section. Fig. 6 is a detail perspective view showing the means for operating the brake from the wagon-body. Fig. 7 is a detail sectional view showing the depending guides of the brake-beam.

a In carrying out our invention we employ a wagon-body A, which is mounted upon the running-gear B,both the wagon and gear being of any suitable or preferred construction. A brake-beam O is provided with brake-shoes 0, adapted to engage the rear wheels B. The brake-beam O rests upon the cross-piece D, connected to the rear hounds of the runninggear, and, if desired, the beam may be provided with depending guides G which engage the ends of the said strip D and serve to guide the brake-beam in its movements. .Thebrake-beam C has a rearwardly-extend segment F adapted to engage the perfora-m tions E, produced in the bar E. The crankarm F has a rod G connected thereto, said rod being pivotally connected at its forward end to the hand-lever H, pivoted at H to the side of the wagon-body.

When the hand-lever is turned forwardly, the crank-arm F is drawn forwardly through the medium of themed G, and the rock-shaft F is turned a sufficient distance to cause the engagement of the toothed segment F with the perforated portion of the bar E connected to the brake-beam C, and this action brings the brake-shoes into contact with the rear wheels. When the hand-lever is thrown rearwardly, the reverse operations take place and the brake is released. In order to provide for braking the vehicle free from the wagonbody or at the rear end thereof, we also provide a curved bar M, which is connected therein to the extended ends of the rear hounds, or it may be connected to the rear axle of the ve hicle. Working upon the bar M'is a handlever N, apertured at N and carryinga gripping-catch N which is operated by means of a spring-actuated lever N in substantially the manner heretofore described. The lever N is pivoted at N in a bracket 0, which is attached to the rear bolster of the runninggear, and pivoted also in the same bracket is a toothed segment P, having an extension P, which is connected at P to a lateral extension P rigidly connected to the lever N. The bracket 0 also serves as a guide for the rearwardly-projecting end of the brake-bar E'.

The operation of the device just described is obvious, it being understood that when the lever is thrown to one side the toothed segment is rotated'upon its pivot and, engaging the rack-teeth E causes the bar E to move rearwardly or forwardly, thereby applying or releasing the brakes, and the operation of the gripping-catch N is identical with the operation of the gripping-catch K. When it is desired to employ the hand-lever at the side of the vehicle, the pin P ,'connecting the extension P and the lever N, is removed, thus permitting the toothed segment to operate without moving the said lever. When it is desired to employ the hand-lever M at the rear of the running-gear, the pivotal connection between the rod G and crank-arm F is removed and the pin P inserted, and the hand-lever can then be operated for the purpose of applying the brakes.

It will thus be seen that we provide a simple and efiicient mechanism for applying the brakes either from the side of the vehicle or at the rear end thereof, and it will also be noted that we provide the improved means for locking the operating-lever at any desired adjustment, thereby permitting the brakes to be properly applied as the circumstances of the case may require.

Having thus fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is v 1. In a brake of the kind described, the combination with the running gear of a wagon, of a brake-beam, a notched bar extending rearwardly therefrom, a segment adapted to engage said bar, a curved bar to the rear of the segment, a lever pivoted adjacent the segment and adapted to work on said curved bar, said lever having a lateral extension, and a removable pin adapted to connect the extension to the segment,substantially as described.

-2. A brake mechanism comprising a movable segment having a rearwardly-extending arm, a brake-beam, a toothed bar connected to the brake-beam and adapted to be engaged by the segment, a lever pivoted beneath the segment, and a link pivoted to the lever and detaohably pivoted to the arm.
