E. GABRIEL; a 4.
`-tle, inthe county'of King and State ol Washington., have invented cert-ain' new and useful 'j Improvements in railway-Car Check-Brakes .offwhichf-.the following is ,-a specification, ref. ference beinghad-thereinA to the accompany--` drawings; l Vlof whleadated to all classes ofcity andsub.-
urban rai way lines, it isespecially intended lThis invention relates to car-brakes, and
' -for use 'upon'cable-cars which are employed A. 'in steepv ascentsi. f1.5
Theobjectof lthe inventionis to rovidefa "simple and 'efficient "chocking-bra e which nray'bereliably used both asa service brake --1nreta1mng vthe car Vat various' stopping "mentary-A to'. the ordinary wheel brake-shoe, tol-.keep the cars provided therewith' at all tim'es under .the .control of the' gripman or other Operaton 1 v .-Yith heseendsin view, the invention' .consists inthe provision of brake-shoe mein.
" bers coupled together so as tooperate in uniso'n and are arranged to be manipulated so as 'to friotionally' engagey the'car-wheels and also.
. the track-rails, together l with means actuated l-terial-lissupplied; to the rails to overcome in applying thefbrake whereby agrit'ty masuch-slip as would occur'frorn the momentum i Call"- -x` The invention further consists in the-novel Construction, adaptation-and combination of parts, .asA willb'e hereinafter describedand drawings, Figure 1 is a sideelevaf i"tionof vthe lendjof a car provided with braking apparatus embodying my invention. Fig. 21
'-3i's aperspec-tiveview. of a-brake-chock with ap'ortion of a track-rail and the. links .whereythe chock is suspended. .4.5i i 'b'odyshown A The 'reference numeral 5 designates a carwith a platform 6 and mounted' such as '7, provided with wheels upona truck,
the body' but, as ordinarily cars, with which the in- ,intended for use, the
dependentlyof 'lvention is primarily body is iixedly connected with the truck gbunk or beam. v
- 1.9 represent brake-shoes, or chocks, which ter-iai. Each of these chocks is formed upon shape at the rear 10 and of va radius corre'-l sponding with that of the car-wheel with l-Which 1t co-acts, while. at the front ,it -flat et 11 toaccommodate. the wheel-flange.
The under fae 12 is madel practically flat and to the inner side at the rear thereof is a :dependin flange 13 which serves as a guide toproper y direct ,the chock upon the .track rai therewith when'brought into operation. The
said arc-shaped faces furnish' tongues whose thereu on. to engage with such faces, and that t e wheel may readily mount the tongues, their extremities 16 are formed to a relatively sharp edge. 4These chocks are severally vsuspended from the said truckfrarne'by pairs of links 17 and 17 which are (gf equal lengths and are pivotally connected by pins, such as 19, or by cross-rods, as 20, connecting the checks. The'` axes of this .pivotal'connection foreach pair of links, at both top and bottom, are s aced equally disthe checks in parallel planes.
To a cross-rodfl between the links 17 is connected a frame 22A which, in tur-n, is connected by a drag-bar 23 with a leverarm 24. Thislever is fulcruined to a support 25 'which is rigidly lsecured to the car-body, while the otherarm 24of the lever extends upwardly throught the :floor 'f the car and terminates-in a head 26 within easy reach ofv the operators foot. 27 is an extensible spring connected to said lever and tending to normally -hold the checks in theinopenativeposition in which illustrated in Fig.) 1. Provided for each ofthe chocks isa ox 28 for sand and which boxes are disposed so that supply tubes 29 leading therefrom will deposit the sand upon the rails immediately to the rear of the respectivechocks. These tubes are each provided with an oscillatory valve, represented by 3f), having a lever handle 31 which are respebtively'connected by rods '32 with the adjacent links 17, and the valves `are adjusted so that they will be opened-ttor the delivery of the sand when the tened, as at 10, and to one side of the urved' portion of vs uch fac'e there is provided a rab-` Pflrts vof theehocks which arev forward of' office is to bear the' Wheels as they -recede* tant apart, consequently t ie links will carry its upCper side to have a face which is arc v and vmaintain the same-in alinement ins 18' with the truck frame above and l at t reir lower ends the links 17 are connected ocks are swung into engaged position and I -Thv operation oiI the ii'ivi'intion is as l'ol lows: 'By pressing down with his l'oot upon thv lvvvr-arin 2li tliv operator ovvi'eoinvs the power ol' thv spring 7 and, 'througlrthv agency ol' thv ha."

Coincidentally with and actuated h v the niovvinvnt oi" the chocks in v'livcting hral-:ing engagement with the rails and the wht'els. the valves 3() in the d eliverv tubes of thv. sand Vcontainers are opened to lihvrate sand which the brakes the car is caused to move. in an opposite direction to roll the wheels troni the.

The'apparatus is readily put'in operation4 esas/i7 shaped Wheel-engaging face, links suspending said checks from the truck, a frame con' nected .with said links, a'lever, a draw-bar' connecting the. lever with said frame, and a spring acting to retain said. chocks in disengaged condition.
2. In apparatus of the class described, thel combination with the Wheel checks, vibratory links supporting said checks, 'a lever', op-
lvrative connections'betweenthe lever and `said links, a spring tending to maintain said chocks in disengaged positions, of devices operative. with the ap lying of said chocks for discharging sand to t e rear of the'chocks.
