To all whom it may concern; y

Be it known that I, CARL F. GERLINGEE, a citizen of the United States. residing in Dallas, in the county of Polk and State of Oregon, have invented certain new and useful Imro'yements in Raiiway-Brakes, of which the ibllowing is a specification.

My invention relates to that classof railway brakes in which, m*hen a. carvheel is derailed, braises are automatically applied to #top the car or the train. l

The object of my invention is to provide pie and reiieble mechanism of this class :in carry-inc out my invention I provide a Yoss-bar extending transyersely across .the ck parallel with an adj stent axle and which extends over the rails of the track. This bar is e )rted on brackets or bars attached to op- 3 iourn ali-botes and it supports a valveifesing connected in any suitabie way withthe -f eine of the brake system. From the )er above mentioned is suspended another crossbar of the saine dimensions which is connected 'with the first-mentioned crossbar by vertical bolts carrying s rings which normaily press the lower Inova )le cross-bar away from the upper stationary one. The arrangement is sueh that when a wheel is derailed the adjacent end of the lower movable cross-bar strikes the rail from which the wheel was deraiied and causes a valve to operate to open the train-pipe and/.permit an' exhaust which will operate the brakes.

, in the accompanying drawings illustrating my invention, r igure 1 is an end elevation of so'much of a car-truck with my improvevmal condition.

Be ow the cross-bar D is another' cross-bar. H which may be of the same dimensions. It is suspended from the cross-bar D. by means of vertically arranged bolts I on W ich are arranged between the bars D and H springs J. The bar H is normally held in the position shown in Fig. 1 by its own weight and by the power of the s rings J. The valve-stem K extends down t rough an opening in the cross-bar D and approaches close 'to the uppor surface of the cross-bar H. Vihen the partsare in the positions shown in Fig. 1, the truck can move in the usual way without interfering with the brake -mechanism but should a wheel become derailed thecross-bar H Willabut against the adjacent rail in the manner indicated in Fi 2 and the cross-bar H will be moved towards the bar D, striking the valve-stem K andopening the valve. This will exhaust the train-pipe and cause As brake-mechanism of this class is often equipped with signals, it is' obvious that when my im roved mechanism operates in the manner a ove mentioned, signals may be applied at various parts of thetrain. As iany sets of the mechanism described as are found necessary in use may be applied to the various trucks. l

The devices are simple in construction, easily made and easily applied Without material alteration in thegeneral construction of the truck or the brake mechanism.

-I claim as my invention:

' 1. The combination with a truck-trame of a cross-bar rigidly connected With thc frame, a cross-bar suspended from said first-mentioned cross-bar and valve-mechanism connected with the train-pipe of the brakemechanism which is operated by said suspended cross-bar.

2. T he combination with thc joui-nalboxes of brackets secured thereto, a crossbar rigidly secured t'o said brackets, another cross-bar of the same length, yieldingly supported from said first-mentioned'cross-bar, and valve-mechanism su ported by the iirstmentioned bar connecte( With the brake sysltaein and operated by the suspended cross- 3.
