SPECIFICATION forming part of Letters Patent No. 285,624, dated September 25, 1883,

Application filed May 14, 1883; (No model.) I

To aZZ whom it may concern..-

Be it known that I, WILLIAM LANE HUT- soN, a citizen of the United States, residing at brake mechanism in connection with the rear portion of a running-gear. Fig. 2 is a'side view, showing the levers thrown forward for applying the brake. Fig. 4 is a side view of the levers, illustrating the operation of releasing the brake.

The brake-beam A is suspended from the rear hounds, B, so as to swing free beneath them, and when moved backward applies the blocks a to the rear wheels, 0.

The means for moving the brake-bar consist of two levers, .D E, which are bent at a right angle, their horizontal portions being journaled side by side in arms d, attached to the rear axle, F. The inner end of the front lever, E, is bent forward at a right angle, and

. is connected-with the brake-beam by means of a rod, 2), and metal plate a, that enters a slot in the brake-beam. Theplate is provided with holes to receive a pin or bolt, (1, that 7 passes vertically through the brake-beam and is held in place by a cap-plate, e, as shown in Fig. 3. By adjusting plate 0 in the slot of the brake-beam A the wear of the blocks a may be compensated for, so that the brake may to the other lever. A ratchet or toothed pawl, F, is pivoted to the upper end of lever E, and extends backward over a catch-plate, g, fixed on the axle G. The front end of said pawl F is turned upward to adapt it to engage with a trip-dog, H, which is pivoted to the longer lever D.

The lever D may be operated by hand; but in this instance I employ a cord, I, which is attached to its upper end,, as shown, and in practice extends forward to the drivers seat.

The operation of my improved brake mechanism is as follows: In the normal position the vertical arms of levers D E are inclined backward, as shown. in Fig. 1. When the cord -I is pulled, the vertical arms of the levers are both carried forward, since the upper end of rock-lever E bears against lever D, and is hence compelled to move with it. In this movement the inner bent end of lever E is thrown down, which obviously has the effect of drawing. the brake-beam A backward and applying the brake-blocks to the wheels. The ratchet-pawl F also comes into action at the same time, and by engagement with the catchplate 9 holds the rock-lever E in the position to which it has been moved forward, and thus keeps the brake applied. On releasing the cordI the spring f throws lever D back, as shown in dotted lines, Fig. 2. Said lever then resumes the position shown in Fig. 1. When it is desired to release the brake, a second pull on the cord I carries the lever D forward again, and this time its dog H comes in contact with the upturned end of the ratchet-pawl F, Fig. 4, and trips the latter, thus allowing the spring f to throw the lever E back to its normal position and allowing the brake-beam Ato swing free, as before. As the rock-lever E is thrown back the trip-dog H slips over the end of the ratchet-pawl F and resumes its 0 former or normal position. It will be perceived, therefore, that the first forward movement of the lever D applies the brake, and that the lever resumes its normal position as soon as the cord is released, and that on the 5 second forward movement of lever D the brake is let off.

The mechanism for operating the brake-bar may be attached to the rear aXle alone, or partly to it and the side of the wagon-body, as found most convenient and practicable.

What I claim is 1. The combination, with a brakebean1, of two levers, a holding-pawl, and a trip device, substantially as shown and described, to opcrate as specified.

2. The combination, with the brake-beam, of the rock-lever E and a ratchet-pawl pivoted thereto, and the main operating-lever D, hav= ing a trip-dog attached, and arranged for acting on the upturned end of the said pawl, all substantially as shown and described.

3. The combination, with the brake-beam, 15

the second lever is moved forward, as shown 20 and described.

WILLIAM LANE HUTSON.
