AUTOMATIC CAR-BRAKE.
SPECIFICATION forming part of Letters Patent No. 238,178, dated February 22, 1881. Application filed December 23, 1880. (Model.)
l c all whom t may concern Se it known that we, AUGUST STENSTROM d AUGUST NILsoN, of Burlington7 Iowa, h 'c invented a new and useful Automatic (3W-Brake, of which the following is a specilicai on.
It; y invention relates to car-brakes in which, on .t down-grade, the pressure of the cars against each other is utilized, in connection with a brake mechanism, to form an automatic brake, and .this we accomplish by the devices and combinations of devices hereinafter set forth and described.
Similar letters of reference indicate similar parts.
ln the drawings, Figure l is a bottom-plan view of'i' a car or truck to which the present invention is applied. Fig. 2 is a front elevation of a car or truck having present invention.
In the drawings, A is a curved lever-arm riivoted` in the bi l'urcated stud B, which is crewecbcentrally into the back part of an orinarylorake-bar, K. One end of the curved :fm Ais attached to the brake-rod x, while le lon ger end, bent upward and again outward, "s int( y he horizontal guide-slot C, in the stai -\nary block D, which is screwed to the botn ofthe car.
E is a push-bar, bifuijcated at e, and fastened :vably upon the curved arm A at g. Thence i passes "orward through a perforation, h, in
c lowe `nd of the brake-operating lever F,
.ich is Ipivoted to the car-front and serves to si ft the push-bar.
The rod .r is attached to the center of the lor lie-bar i' of the other pair of wheels in the same truck by a stud, B', similarin form to the st"r1 B, through which passes the curved arm To the shorter end ofthe curved arm A' is attached the brakerod whose oppositeend is attached to the stud B. To the longer end of the curved arm A is fastened the rodi, which runs forward and is attached to the brake-chain oit' an ordinary brake.
The operation is as follows: By the handlever F the push-bar E is brought into position directly under the buffer of the car, whereupon, by the pressure of the cars against each other on a down grade, the longer end of the curved arm A is shoved backward in its slot. O by the push-bar, thereby drawing forward the rod a', thus pressing the brake blocks and shoes upon both pairs of Wheels.-
The brakes maybe loosened by simply turning the outward end ofthe push-bar from beneath the buffer.
For breaking other than on down grades the ordinary hand-wheel may be used.
lt is evident that the device described can be attached to both ends of the car.
What we claim, and desire to secure, is-
l. Thecombinationofthepush-barllfl,curved arm A, stud B, stationary block D, provided with slot G, hand-lever F, rod or, and the brakebeams ofan ordinary car-truck,with the curved arm A', the stud B', the rod rr', substantially as and for the purpose described.
2A The combination of the bar E, arm A, stud B, block D, provided with slot C, lever F, rod curved arm A', stud B', and rod x', with the rod 1 the brake-beams of an ordinary truck, and the brake-chain of an ordinary brake, sub stantially as and for the purpose described.
