NITED STATES PATENT OFFICE.

HENRY LESLY, OF BIRMINGHAM, ALABAMA.

RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 395,066, dated December 25, 1888.

Application filed October 11, 1888. Serial No. 287,866. (No model.)

T 0 all whom it may concern.-

Be it known that I, HENRY LESLY, of Birmingham, in the county of Jefferson and State of Alabama, have invented a new and Improved Railway-Switch, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of my new and improved railway-switch. Fig. 2 is a sectional elevation of the same 011 line m w of Fig. 1. Fig. 3 is a similar view taken on line y y of Fig. 1; and Fig. 4 is a transverse sectional view on line 2 2, Fig. 1.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

In the drawings 1 have shown two switchframes, A A, each composed of two pointed rails, a a, connected together by cross-pieces c c and c. The said frames are each pivoted between the rails B B C Cby a bolt, d passing through the center of the cross-piece 0, so that the blunt ends of the rails to a abut against the ends of the said rails C C.

The two frames A A are operated for opening and closing the switch by the leverD, fulcrumed on shaft D, jonrnaled in the blocks D D at the side of the track. The lever D is formed with an enlarged head, (1, and connected to this head by the studs d d, on opposite sides of the shaft D, are the connecting-rods D D These connecting-rods pass under the rail B and are connected to the arms E E of the switch-frames A A. By turning the lever D the two rods E E are simultaneously operated in opposite directions. Each of the connecting-rods D may be connected to the arm E or disconnected therefrom at pleasure, so that either switch-frame A may be operated independently of the other by the same lever, D, or both switch-frames may be operated simultaneously in opposite directions by the lever D, if desired.

The ends of the connecting-rods D maybe connected to the arms E in various ways to permit ready connection and disconnection; but I pefer to slot the arms E both vertically and horizontally, as shown at e e, to form the projection e at the end of each arm, as shown clearly in Fig. 2. The ends of the connecting-rods E are notched to form the hooks f and shoulders or offsets f, (see Fig. 4,) and they are placed in the slots 6 6. By shifting the connecting-rods E laterally in the said slots 6 they may be made to engage with or disengage the projections 6 as shown in Fig. 2. lVhen moved in line with the vertical slot 6, as shown at the right in Fig. 2, the connecting rods move independently of the switches. When moved out of line with the said vertical slots, as shown at the left in Fig. 2, the movement of the connecting-rods operates the switches. Normally, the said connecting-rods D are held to engage the arms E by coiled springs F on rods F, the springs acting between fixed collars g 011 the rods and the sliding washers g on the said rods F. For drawing or moving the said rods from under the projections e to disconnect the rods from the arms E, I use the levers G, pivoted outside of the track and connected by cordsor wires G G to the connecting-rods D8. The said cords 0r wires pass around the pulleys H, so that when the levers G are turned out ward away from the track the said connecting-rods will be drawn out from under the projections e into the vertical slots e,-thus eifecting the desired result of disconnecting the said connecting-rods from the switchframes. The levers G may be held back by pins 72, and by removing these pins the springs will automatically force the connecting-rods over to engage with the arms E. The cords G might be connected directly to the connecting-rods D but I prefer to use the T-pieces or blocks m, passed through slots on in the connecting-rods D as shown clearly in Fig. i, so that the said cords may be fastened to the outer ends of said T-pieces or blocks.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The pivoted switch-frame A, comprising pointed rails a and suitable cross-pieces, and provided with an arm, E, formed with slots e e and projection 6 in combination with the connecting-rod D formed with notched end f f the rod F and spring F, to act upon the said connecting-rod, and the operating-lever D, substantially as described.

2. The combination of the operatingdever ICO from the arms E E, in con'lbinz'ltion with the single operating-lever I), to which the rods D D are connected, the levers G Jr, and cords G, passing over the pulleys 11', substantially AS 1 described.
