LOUIS V. STEVENS, or BUEEALO, NEW YORK, AND JOHN E. Mo'r'r, OE CLEVELAND, OHIO.

RAILWAY-SWITCH.

SPECIFICATION forming'part of Letters Patent No. 501,112, dated July 11, 1893.

Application iled April 21, 1892.

To all whom it may concern,.-

Be it known that we, LOUIS V. STEVENS, residing at Buffalo, county of Erie, State of New York, and JOHN R. MOTT, residing at Cleveland, in the county of Cuyahoga and State of Ohio, citizens of the United States, have invented new and useful Improvem entsin Railway-Switches, of which the following is a speciication.

This invention relates to a new and improved device for operatin g railway switches; and it consists in certain details of construction and combinationof parts all of which are hereinafter fully described and specifically claimed.

The invention is clearly shown in the accompanying drawings, whereon- Figure l is a perspective view of that portion of the mechanism which is located between the railroadrails. The dotted lines represent the curbing, or frame of the pit in which said mechanism is located. Fig. 2 is a transverse section of the railroad-rails, and a switch-rail with that portion of the mechanism which is directly connected therewith, also a frame located below, and supporting said parts. Fig. 3 is an edge view of a transverse frame arranged below the central part of the mechanism for supporting the mainlevers thereof. Fig. 4 is a plan of the under side of the platform arranged above the operating ends of the levers, showing also the under surfaces of the lever trips and means for retaining same in position. Fig. 5 is a plan of the upper side of the aforesaid platform, with openings in which the trips are adapted t0 operate. Fig. 6 is a sectional View of the front platform of a car, with mechanism for operating the switch, from the car. Fig. 7 is -a vertical section of Fig. 6 taken through one pair of the hinged levers.

On the drawings the dotted lines A, see Fig. 1, designate a curbing of frame arranged Within a pit located between the railroad rails for the reception of that portion of the mechanism which is connected with the switch-rail.

B is a metal-frame arranged transversely, at or-about the center of the pit, so that its outwardly projecting ends b b shall rest under the rails and be secured thereto over the Serial No. 430,115. (No model.)

stringers C. C. in order that the proper position of the frame B. carrying the operative parts may be assured in case the stringers should sink away from the rails.

The lower portion of the frame B has a pair of journal-boxes D, D', riveted, or otherwise secured thereto, for receiving the fulcrumpins d d of a pair of levers E, E', to the forward ends of which are pivotally connected the rods F, F', each having a pair of plates f, f', hinged, or pivoted in the upper ends thereof, as shown atf,f, in Fig. l.

The letter G, designates a plate, or platform, which forms a cover for the forward end of the pit. This platform is provided with two rectangularopenings g g within which the hinged-platesff are adapted to operate.

The outer end of each hinged-plate f, is provided on its under side vth a stirrup h to receive one of the projections t' c" of theplates l, l, which are arranged under the platform G, as shown in Fig. 4, to prevent displacement of the hinged plates f, during the operation of same.

The opposite, or rear ends of the levers E, E', are connected by means of links Z Z with the opposite ends of a triple-armed crank M, which is journaled in abox m, that is secured in the bottom of a metal frame N arranged across the pit, with upper projecting ends, resting on the stringers, C C', and with the railroad-rails secured on said projecting ends, as shown in Fig. 2. The central arm of the triple-crank projects upward and is connected by a link o, with a lever p that is pivoted in a box q, so that the upper-slotted end of said lever p, shall engage the downwardly projecting-pin 1,0f the switch-rail 2.

The end platform P, of-each car, see Fig. 6, is provided at each side of the longitudinal center thereof, with a device through the instrumentality of which, the driver or other attendant may operate the switch as desired, without checking the speed of the car, or dismounting from same. These devices consist each, of a vertical standard 3, having a camlever 4 pivoted in the upper end'thereof, a link 5 pivotally connected with said lever, a hanger 6 secured to the under side of the platform at a point below the vertical-stand- IOO ard thereof, a lever 7 pivoted in said hanger, a roller or idler 8 journaled in the lower end of the lever 7, and a series of perforations in the upper end of lever 7 for receiving a pin 9 whereby the lower end of the link 5 is ad justably secured, as the height of the car may require.

In the operation of our invention the driver has simply to press downward the handle of one of the levers 4. This movement depresses the roller or idler of said device causing same to be brought into position for engaging the hinged plates necessary to shift the switch rail as desired; forinstance it it is desired to throw the point of the switch-rail to the right the lever 4 on the right hand side of the car is thrown down causing the attached roller or idler to be brought down so as to engage the right hand set of hinged plates f, f', which on being forced down carries with them the rod F. This depresses the attached end of the lever E, throwing its forward end upward and tipping with it the triple-armed crank M, to the left. This motion throws the lower end of the pivoted lever 19 to the left and consequently moves the switch rail 2 attached to its upper end to the right as desired. During the operation just described the left hand set of hinged plates ff. are thrown up ready for engagement with the left hand roller on the car when the switch rail is to be thrown back in the opposite direction or to the left.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, ism 1. In a railway-switch, the combination ot' the pivoted levers E E', triple armed-crank M, links Z, Z', o; pivoted lever p, and the switchrail having a downwardly projecting-pin, as described, with the rods F F', connecting hinged-plates ff', and the platform G having rectangular openin gs therein, substantially as and for the purpose set forth.

2. The device for operating the switch rail 2 having a downwardly projecting pin, consistingof the pivoted lever p. the triple armed crank M. the link c adj ustably connecting the lever p and crank M. the links Z Z rocking levers E. E. rods F. F hinged platesff pivoted to said rods and platform G. having rectangular openings therein all combined and adapted to be operated by a device upon the car for depressing said hinged plates substantially as shown and described.

3. A device for operating a switch rail consisting essentially of a pair of separately pivoted levers located below the surface the arms on one side of the pivots beingconnected with devices at the surface for depressing their outer ends and the outer ends of the arms on the opposite side being pivotally connected to opposite arms of a pivoted triple armed crank the central arm ot' which being connected to and moving the switch rail substantially as shown and described. i

In testimony whereof we affix our signatures in presence of two witnesses.
