AUTOMATIC WAGON BRAKE APPLKGATIOH FILED 0 31225,

Patented Jan 28, 1913 1 v wow:

r. This rod is adapted to be carried downwardly in front of the lever 19 so as to prevent the same from swinging in a direction to apply the brake. The upper end of the rod has a bend 32 which enters a recess 33 made in'thetop edge of the side wall of the wagon box as shown in Fig. 3. When this-bend is within the recess, the rod is in elevated position, and its: lower end is out of the path of the flever 19. To place the rod in operating 'ition, it is lifted sufficiently to remove bend 32. from the recess 33, and the rotfis then turned until the bend clears the-'sidfilwall of the wagon box, after which the I may be pushed downwardly so'as to'ei (1 into the path of the lever 19, and pre the same from swinging in a direction o apply the brake as already described" The we (in isat" provided with an auxiliary bra e designed for preventing the wagon from backing; down a hill. This auxiliary brake compr ses a stem 34 pivotally' connected in any suitable manner to the hind axle 5, and pointed at its free end, so that when it is swung down into contact with the ground, said pointed end will enter the same. The rodis held in elevated osition by means of a line 35 connected thereto near its free end, said line being also connected to a lever 36 pivoted to the side i of the wagon bcdyindjacent to the drivers seat to be within easy reach of the driver. The lever is provided with a suitable guide and locking device 37. Upon swinging the lever rearwardly as shown by dotted lines in Fig. 1, the stem is permitted to lower so as to come in contact with the ground, and in this position it serves as a prop to prevent the wagon from traveling rearwardly,

which is useful when ascending a hill, as

the wagon may be stopped to allow the team to rest. Upon swinging the lever 36 forw rdlyg-the stem is swung upwardly into in oparative position.

i The loose connection between the

rods

25 and 26 is provided in order that the tongue when the wagon is making' a turn.

10 may swing around with'the .front axle 6 The disk 23 is provided with a plurality of perforations 24,'in order to provide for the adjustment of the connection between said disk and the rod 25 as well as the chain 28.

I An adjustable connection between the rod 27 and the lever 19 is also had by providing the latter with a plurality of openings as shown in Fig. 2, with any one of which openings the rod may be connected.

A' spring 38 is interposed between and beam 41 under certain conditions, said lever having a bolt 42 connected to one end thereof and adapted to enter an opening within a beam 43 similar to the beam 31 hereinbeforedescribed. This bolt is connected to the short arm of said lever while the long'arm of said lever has a chain 4.4 or the like extending upwardly therefrom whereby the lever can be swung upon its fulcrum so as to force the bolt 42 into the opening in the beam 43. When the bolt is thus positioned, the brake beam 41 is held against movement relative to the beam 43 and the vehicle can be backed without the application of the brake.

It is to be understood that openings may be formed within the" rod 27 at regular in tervals, as indicated at -51 so as to permit said rod to be connected to the level- 19 no matter what the dis'ance may be between said lever and the el unent 23.

What is claimed is: V

L'The combination with a vehicle body and running gear, and a neck yoke, of a swinging brake beam carried by said gear, a lever pivoted to the gear, a connection between one end of the lever and the brake beam, a movable member carried by the. tongue at its outer end, a connection between said member and the other end of the lever, 9

a connection between the movable member and, the neck yoke, a cross bar carried by the running gear between the brake beam and the lever, said cross bar having an opening, a rod mounted insaid opening and adjust-able to extend at its lower end in front of the last mentioned end of the lever, the upper end of the rod having a downward return bend extending into a recess in the top edge of the side wall of the vehicle body. 2. The combination with the running gear of a vehicle, and a neck yoke, of a brake beam mounted to swing and suspended from i the running gear, a lever on the running gear, an adgustable pivot connection between one arm of the lever and the brake beam, adisk mounted for rotation on the tongue of the running gear and having a plurality of openings adjacent the er-iphery thereof, a connection between the diskand the other arm. of the lever, this connection being adapted to be seated in any one of the 0 enings, said openings being equidistant rom the center of the disk, and a flexible'connectionbetween said disk and the neck yoke, said connection being adapted to rotate the disk and apply the brake beam when the running gear moves forward relative to the k mounted far rotation on the tongue am running; gear and having a plurality awnings adjzment the periphery thereof ugidisiant fmm the Renter 0f the disk, Zion bet Wiaen the disks and the ofher 1 arm in he lever and adapted to be seated in mu; of ihe upenings, a flexible connechwlwmm said; disk and the neck yoke, (OHIQQCUOU being adapted to rotate the the brake beam when thy ZiZUVBb iim'ward relative to th l 'MOVEIHQHL 1V Hm?
