.N0 MODEL.

with steel abutment-pieces It at their external ends, and the end portions of these steel 'abutment-pieces aresuitably hardened By `means of screws these abutment-pieces itv are regu-l lated in. such la manner thaton collision ofy same 'with the appliance in connection with the; locomotive, which will be described later on, an electric circuit is closed in a reliable manner, owing -to the contact made between the brass pins e and the disk c; but the brunt of thecollision is received .by the head a for the purpose stated later on. Obviously these abutment-pieces -t Inustbe well insulated from the .casing a, and the latter must be constructed to l.prevent the'acce's's of dust or moisture.

To this end I provide a layer z, ofA suitable material, at theV openings of the `ins\1lating sleeve b.

l`he whole contact device z' is oscillatory, supported in a casing k, `and carries a'copnter- 'weight `l,`as shown-in Fig. 3. The casing' Isis located between the rails and closed by asuit- 4a'ble lid. Normally the. contact device a' will A wire m in connection with the counterweight 'Z leads ina suitable well-known-way'- tothe next linemans station-house.l Vthen` the line is clear, the lineman by pullingthe wire 'm canplace the contact device into its inoperative position, as illustrated in Figp in full lines, Wheny'the head a Willl restl on a projection von the lid of`.,the 'casing c.

The train-pipe of the brake mechanism of l' tlie 'looomotive, which'may utilize air-pressu're or be a vacuum-brake, or a lbranch of this pipe is led below the locomotive and pro vided with a tap-valve n. at its lowest portion. This valve n is fitted at both sides Withdownwardly-extending lever-arms '0, as illustrated in Figs. 4 and 5. 'A plate p connects thetwo ,lever-armsotogether at their lowest portions. This plate p, Ywhich' has its bottom end' bent somewhat forward-ly, is situated low enough under the locomotive so that the erected contact device .v1 will strike same at about its center The valve n is suitably constructed in such a -way that it can be operated independently of the contact device herein'beforedescribed byA the locomotive attendants; -If for any reason a moving train has to be stopped-c'. e. when lthe line same has to pass is not clear-the nearest lineman leaves the contact `device c' in its upright operative position. The locomotive'of the train 'when arriving at the contact devicewill strike, with its plate p againstthe latter,

.whereby the valve n, and in consequence the brake mechanism of the train,will be actuated and the train causedato stop. At the same time the collision between the plate p and the abutment-pins L. of the contact device 2' will cause an electric circuit t be closed by the brass? pin e being .forced into Contact with the disk e, so that an audible or visible signal will be automatically given at the nearest stations.

- What I claim as my. invention-,f.and desire to secure by Letters Patent, is-

1.' ,Apparatus for stopping trains and signaling, comprising a projecting head, elec-y tricall contacts carried by said head,l 'a device carried by a moving trainadapted to be op'- erated upon striking said head, said electrical contacts being so located on the head lthat they will be struck and operated by said, device, substantially as described.

-' 2. 'Apparatus for stopping trains and'sig-j y naling; comprising a counte'rweighted pivoted head, and means for raising or lowering it between the rails, an `'electrical contact-devicev carried by-said head and conductors therefor, in combination with a device carried 'by a train adapted to strike said head toope'rate the;

contact and itself be operated by thev force of impact, substantially as described. l

'3. Apparatus for stoppmg trains and signaling, comprising ahead projecting above the rails, an abutment-piece it at one .part ofthe. head, an electrical contact' device adapted to be operated by .said piece L and a device carried'by a train adapted tostrike said piece Il.

to operate the contact and itself be operated said head, substantially as' by impact against described. v

4. Inapparatus for stoppingrailway-trains from the line and for signaling lpurpo ses;.the' combinationof a contact device Vsupported be- -tween therails; `means for actuating the brake mechanism of the train by said contact device: a brass disk c in connection with one terminal of a source of electricity,said disk located in the center of van insulating-sleeve b inthev of the contact device; a pair ofA brass pins e, one at each side of the'aforesaid disk c; spiral springs d for keeping the brass pins e lnormally a short distance from' the disk o; .means for' preventing the rotation of `the said 'brass pins e; and brass` con'tact-springsfg, bearing against the movable pins e, in connection with the second 'terminalof the o'urce ofelectricity..

substantiallyas describe and-shown.

In witness whereof I have -hereuntosl'gne roo Ixo

my name, this 15th day of March, 1902, in the l `presence of two subscribing witnesses.
