RAILWAY TRIP-SHOE.

' Y I -SPECIFICATIONforming part of Letters Patent 1131793375, dated June 27, 1905.

. Application filed January 8, 1904. Serial 110.188.201.

To (all who! it lit/1. concern.-

Be itknown that LCHARLEs M. HURs'r,acitizen of the United Statcs,and a resident ofltaw- Y lins,count,v of Carbomand State of \Vyoming, have invented certain new and useful Improvements in Railway Trip-Shoes, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof, Y v

This invention relates to trip-shoes carried by locomotives or railway-cars for the purposeof engagingswitchorsignal trips located Its object is toprovide a reliable and easily-controlled device of this character.

The invention consists in a shoe carried by a threaded rod running in a suitable easing and'controlled by means of a nut, which may be actuated from the interior of the caror englue-cab.

Ihe lnventlon 18 illustrated n the accompanylng drawings, in wh1ch Figure 1 1S adctail side elevationof a locomotive, some portions being broken away, showing the shoeand its operatlng mechanism attached thereto. Fig. 2is a'detail elevation,

partly in section, through the track andshowing the shoe and a part ofthe locomotives truck. Fig. 3 is a detail of the controlling mechanism. F ig. 4 is a vertical section on the line 4 4 of Fig. 2, and Figs. 5, 6, 7, and 8 are details of various parts of the'device.

The shoe is preferably attached to the truck.

of the tender of a locomotive, as shown in Fig. 1, and controlled. by means of a hand-lever within the engine-cab, a suitable cable leading from the cab to the nut for turning the rod supporting the shoe. While itis obvious of a suitable bracket 13, to the framing 14 of the truck of the tender.

Within this casing there IS lIOIISEd a vertically-reelprocating bar 15, provided at its lower end with a flange 16, to which the shoe 17 "is secured by means of bolts 18 18 passing loosely through apertures in the flange and fixed within the shoe, so

.and springs 20 21 react, respectively, between the back of the shoe and the lower face of the flange 16 and the upper end of the shoe-stem 19-and the inner wall of the chamber in the bar 15, within which this stem is housed, these springs operating to hold the shoe in its lowest position relatively to its carrying-bar. The upper end.22 of the bar is threaded, and upon this thread runs a nut 23, the shell of the casing 12 being suitably apertured to accommodate it. This nut 23 is annularly grooved, and around it is turned an endless cable or chain 24, leading to and turning over a sheave 25, carried by a bracket 26, secured to theunder side of the seat-board of the engine-cab. The cable 24; is guided intermediate of the. nut and the sheave 25 by suitable leaders, as 27, secured to the end sill of the tender 28, secured to the steps of the locomotive, and sheaves 29, securedto the rearward end of the seat-board of the engine-cab; j

- To compensate for the play of the draftrigging, by which the tender is attached to the locomotive, withoutdisturbing the tension of the cable, I mount the sheaves 29 on ashaft journaled in blocks 30, sliding on the bars 31, carried by brackets 32, attached to the engine-cab, and interposed between the blocks 30 and forward bracket 32 are springs 33, which force the blocks backwardly and keep the cable taut. Upon the shaft carrying the sheave. 25 and fixed. to "the sheave is mounted a sprocketwheel 34, upon which is mounted asprocketchain 35, turning over a sprocket-wheel 36, mounted, with the hand-lever 37,within thecab of the engine and within convenient reach of the engineer. The lever- 37 plays over a quadrant 38 and is provided. with a latch mechanisgn 39 of ordinary construction, cooperating with the quadrant. The relative size of the sprocket-wheels 34 and 36 is such that a halfturn of the latter rotates the former several times, thereby turning the nut 23, so as to secure the desired vertical movement of the shoe 17.

The form of the shoe may of course be varied. It is'as shown particularly adapted for contact with an apron form of trip, as shown a't-10,-being the trip which forms the subject-of a copending application for patent by myself.

It is obvious that various forms of mechanism may be employed for turning the nut to raise'and lower the shoe, and it is also apparentthat a plurality of" shoes may be used as, for example, upon opposite sides of the train.

I claim as my i'nvention' 1. In a device of the kind described, in combination, a casing, a shoe, a threaded recipro eating. bar housed within the casing and carrying the shoe,-and a nutrunning on the bar and.

reacting against shoulders on the casing.

2. In a device of the kind described, in combination, a casing adapted for attachment to a rail way-vehicle, a shoe, a threaded reciprocating bar housed within the casing and carrying the shoe, a nut running on the bar and'rcacting against shoulders on the casing, and means for controlling the nut from within the vehicle.

and leading to another vehicle, guides for the cable arranged to deflect it from a straight course, one of such guides being yieldingly supported.

5. In a device of the kind described, in com,

bination, an extensible shoe mounted on a railway-vehicle, a cable for controlling the shoe and leading to another vehicle, guides on each vehicle for the cable and arranged to deflect the cable in a line transverse to the direction of movement'of the vehicles, one of said guides being yicld'ingly supported.

6. In a device of the kind described, in com bination, a controlling-cable for leading from one vehicle to another and a guide therefor comprising a bracket, journal-blocks,sliding on the bracket, a spring bearing against the blocks, and a sheave carried by the blocks.
