HENRY S. GOUGHNOUR, OF J OHNSTOWN, PENNSYLVANIA, A SSIGNOR TO THE JOHNSON COMPANY, OF LORAIN, OHIO.

S LACK-ADJUSTER.

SiECIFIGATION forming part of Letters Patent No. 550,045, dated November 19,1895.

Application filed September 14, 1895- Seria1No.562,530. (No model.) i

To all whom it may concern.-

Be it known that I, HENRY S. GoUGHNoUR, of J ohnstown, county of Cambria, State of Pennsylvania, have invented a new and useful Improvement in Brake-Rigging for Railway-Oars, of which the following is a true and exact description, due reference being had to the accompanying drawings.

7 My invention relates to certain improvements in brake-rigging forrailway-cars, and has for its object to provide a simple and efficient means for adjusting the length of the tension-rods. I

Referring to the drawings, Figure 1 shows a side view of a portion of brake mechanism embodying my invention. Fig. 2 is a top View of Fig. 1. r r

1 is the customary brake-beam, extending across the truck and carrying the brake-heads 2 and shoes 3, adapted to engage the wheels. The shoe is brought into engagement with the wheel by means of a pull upon rod 4 and is normally held away from the wheel by means of a spring. (Not shown.) As the shoe 3 and other portions wear, it becomes necessary to adjust the length of the rod 4, and it is to provide means for this adjustment that my invention is intended.

The rod 4 is split on its end so that it passes each side of the brake-beam 1. Through a slot 5 in the forked end of the rod pass the two keys or wedges 6 and 7, which may be held in position by means of the split keys 8, passing through holes 9 in the wedges.

To increase the working length of the rod 4, it is only necessary to remove the keys 8 from one or both of the wedges and slip them out a little, so that they do not occupy so much of the slot 5, thus allowing the beam 1 to drop back a little. Similarly, to take up wear it is only necessary to push the key 6 or 7 through a little farther.

I do not confine myself to the precise construction shown, as various types of brake mechanism may require variations of the exact construction here shown.

Having thus described my invention, what I claim, and desire to protect by Letters Patent, is-

In a brake rigging for railway cars, in combination, a transverse brake beam, a longitudinally extending brake rod, said rod having a forked end adapted to embrace the brake beam, a slot in said forked end, and a pair of wedges in said slot and adapted to act upon said brake beam, and means for locking said wedges in position.

In testimony whereof I have affixed my signature in presence of two witnesses.

HENRY s. GOUGHNOUR.
