To all whom it may concern:

Be it known that I, CHARLES F. CRAW- roan, a citizen of the United States, residing at Liberty, in the, county of Sullivan, State of New York, have invented certain new and useful lmprovernents 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.

This invention relates to new and useful im oroveinents inwagon brakes.

tyne object of the present invention is to provide a novel and improved wagon brake head which is so constructed and arranged that the pole canbe raised while the brake is applied or set.

Another object is to provide a novel and improved device of this character wherein great leverage is possible to apply the brake.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawin In the drawing:

Figure l is a top plan view of the front portion of the running gear of a farm wagon showing my improved brake thereon.

Fig. 2 is a front elevation of the same, partly in section.

Fig. 3 is a side elevation, one of the wheels being removed.

Fig. 4 is a perspective view of the yoke removed.

Fig. 5 is a perspective view of the brake lever.

Fig. 6 is a side elevation of portions of the running gear of a farm wagon, showing a modified form of the invention in connection therewith, in which the yoke depends below the hound.

Fig. 7 is a top plan view of a portion of the running gear of a wagon with the invention applied thereto.

Fig. 8 is a perspective view of the yoke and brake lever removed from the vehicle.

Referring particularly to the accompany ing drawing, in Figs. 1 to 5, 10 represents the front axle of the running gear of a farm wagon, and 11 the hounds of the draftpolo 12, which hounds are pivotally connected to the hounds 13 of the axle. Secured to the upper face of each of the hounds 13 is a metal plate 14, the forward end of which is formed with a bearing eye 15 for the reception of the inturned pintle 16 of the arm 17 of a yoke 17. This yoke extends from one plate to the other, and straddles the hounds 11., in such manner that the pole can be readily swung upwardly, without interference with the yoke, or the operation of the brake. Sup ported on the front axle hounds 13, is the transversely disposed brake beam 19. Formed centrally in each of the arms of the yoke 17 is an apertured enlargement 20 which re ceives therethrough a pivot bolt 21, which bolt is engaged through the forward end of the rod 22. The other end of this rod is disposed through one end of the brake beam and held in position by the nuts 23. Nuts 2%. hold the rods 22 to the arms of the yoke.

Extending vertically from the center of the transverse portion of the yoke is a stem 25 which is adapted to be received in the socket 2 6 of brake lever 26, the upper end of said lever being forked for the reception of the foot of the operator, as will be understood.

It will be noted that the arms of the yoke are bowed forwardly, thereby increasing the leverage when power is applied to the brake lever.

Referring particularly to Figs. 6, '7, and 8 which show the modified form of the brake and its application to the vehicle, 26 represents the axle of the vehicle, 27 the front hounds to which is pivoted the pole 28, and 29 the brake bearn. Mounted on the upper face of the forward end of each side bar of the front hounds 27 is a bearing bracket 30. A yoke, as shown in 8, designated as a whole by the letter A has its parallel and vertical arms 31 formed with inturned terminals 31 which engage pivotally in the brackets 80, said yoke depending below and extending transversely beneath the forward ends of the front hounds 2?, and the rear ends of the tongue hounds 28. Pivotally connected-to bolt 4.0 in the intermediate portion of each arm 31, and to each end of the brake beam 29, isa rod or link 32, by means of which movement is coinniuni ated from the yoke to the brake beain. h link is held on its bolt lO by means 1. nut ll. Depending from the center of the transverse portion of the yoke, and formed integrally therewith, is a lug towhich are pivotally connected a pair of forwardly extending links Straddling the pole 28 adjacent the for ard ends of the links 3% and having its legs pivotally connected tothe pole, intermediate their lengths, is the bifurcated end of the brake lever 36. To the lower ends of the legs 35 are pivotally connected the forward ends of the links 34. The outer or forward end of the lever .36 is formed with an eye 37 to which a rope (not shown) may be secured for rocking the lever to cause the movement of the brake beaminto brake applying position.

It will be noted that the arms of the yoke 17 of the first form are longitudinally curved, and that the arms of the yoke A are straight, I wish it understood that the arms of the first yoke may be straight and those of the other yoke curved, as desired, without departing from the spirit of the invention and the scope of the appended claims. I

The first form constitutes what is termed a pushbrake wherein the operator actuates the brakes into set or applied position by pushing forwardly on the lever, while the 'second'formis termed a pu ll brake, wherein the operator applies the brakes by pulling on the brake lever.

ference residing inthe mounting of the yoke above the hounds, in the first instance, and

mounting the yoke belowthe hounds in the The principle involved is the same in both forms, the diffirst form, whereas in the second form the 2. In a vehicle brake, the combination with the front axle hounds and the brake beam and forwardly extending rods carried by the beam, of bearing eyesmounted on the hounds, a yokehavingthe outer ends of its arms turned inwardly and rotatably supported in .said brackets, the said beam rods being pivotally connectedwith the id termediateportionsof the-arms. of the yoke,

and an operating connected with the intermediate portion of the bight of -the yoke for rocking the same.

In testimony whereof I affi x my signature in the. presence of two witnesses.
