JOHN HENRY JENNER, OF LEAVENWORTH, INDIANA.

WAGON- BRAKE.

SPECIFICATION forming part of Iletters Patent No. 691,547, dated January 21, 1902.

Application filed July 22.11901.l Serial No. 69,239. (No model.)

To all whom it may concern.:

Be it known that l, JOHN HENRY JENNER, a citizen of theUnited States,residing at Leavenworth, in the county of vCrawford and State of Indiana, have invented certain new and useful Improvements in Wagon-Brakes and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

The object of my invention is to provide a Wagon-brake which is simple of construction, easily and conveniently operated, and adapted to be quickly applied and removed.

To this end the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described,and particular view on line 4 4 of Fig. 2.

Referring now more particularly to the drawings, the numeral 1 designates the rear axle, the numeral 2 the rear wheel, and the numeral 3 the rear hounds of a wagon or vehicle of ordinary or any preferred construction.

Pivotally mounted upon the forward portion of the handle 3 is a transverse bar 4, which is provided with loops or bearings 5, in which is mounted a swinging yoke or hanger 6. This hanger is of U form and has its arms projecting downwardly, and to'said arms is connected by upper and lower sets of nuts 7 and 8 the brake-beam 9, carrying the brakeshoes 10, which are adapted to bear against the wheels 2. By this construction the brakebeam is mounted to swing upon the bar 4 toward and from the wheels 2 and may be applied to and released` from the hanger 6 by applying or releasing the nuts 7 and 8 in a manner readilyunderstood. Thebrake mechanism, with the exception of a single brakerod, is mounted upon said beam, so that it can be applied to and removed from the frame with the beam.

Journaled in bearings 1l upon the rear portion of the beam 9 is a shaft 12, provided with cranks13 and 14. The crank 13 is joined tolthe forward end of a brake-rod 15, which is connected at its rear end to the rear axle 4. The crank 14 carries loops or sockets for the reception of .a hand-lever 10, which is suitably secured thereto, so that by operating the lever back and forth the brake-shoes will be operated and released in the manner hereinafter described.

Pivoted to the crank-arm 14 is a ratchettoothed L-shaped bar 16, the teeth of which are adapted to engage or slide upon a fixed pawl or projection 17 on the front edge ofthe beam 9. This ratchet-toothed bar has connected thereto a rod 18, which is operated by a pivoted hand-lever 19 to engage andrelease the bar whenever desired.

In operation, when the lever 10 isthrown forwardly the crank-shaft 12 is turned to bring the crank 13 to an upright position, whereupon the brake-beam 9 is drawn rearwardly and the brake-shoes 10 brought into contact with the wheels 2. When, on the other hand, the lever is thrown rearwardly,

the crank 13 is moved toa horizontal position,

lengthening, instead of decreasing, the distance between the brake-beam 9 and the rear axle 4, thus causingthe brake-beam to swing forwardly on the movable hanger 6 and to thereby withdraw the brake-shoes from engagement with the wheel. When the crankshaftris adjusted to the desired position to hold the brake in and cnt of action, the ratchet-toothed baris engaged with the fixed pawl to hold said shaft against movement, and when this is done the brake-beam is prevented from swinging and the brake-shoes are held in engagement with the wheels. When the lever is thrown in the opposite direction to release the brake-shoes fromengagement with the wheel and the ratchet-toothed bar is engaged with the fixed pawl,the shaft is also held against movement and the brake-beam thereby held retracted and prevented from swinging on the transverse bar 5. Any other suitable form of latch mechanism may be employed in place of the fixed pawl and ratchettoothed bar to perform this function.

When the brake mechanism is used upon IOO box vehicles, the operating handle or lever herein shown may be dispensed with, and suitable connections provided by which the crank-shaft may be operated from the front of the vehicle.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood, and it will be seen that the invention provides bra-ke mechanism of which the operating parts are carried solely by the brakebeam and are readily and conveniently removable therewith.

Changes in the form, proportion, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention,what

I claim, and desire to secure by Letters Patmy hand in the presence of two subscribing 35 witnesses.
