ABRAHAM GULF, OF MOUNT CARMEL, PENNSYLVANIA.

FROGLESS SWITCH.

SPECIFICATION" forming part of Letters Patent No. 350,662, dated October 12, 1886.

Application filed June 21,1856.

To all whom it may concern.-

Be it known that I, ABRAHAM CULP, of Mount Carmel, in the county of N orthumberland and State of Pennsylvania, have invented a new and and Improved Frogless Switch, of which the following is a full, clear, and exact description.

My invention relates to the construction of a frogless switch that is so arranged that the strain incident to the shifting of the switchingrail is distributed throughout the length of said rail instead of falling, as usual, upon one point, and thereby causing a bending of the rail.

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

Figure 1 is a plan View of my improved form of frogless switch, the switch stand being shown in partial section. Fig. 2 is a crosssectional view taken on line as aof Fig. 1.

In constructing such a switch as the one illustrated in the drawings above referred to I provide a switching-rail, 2, that is secured in any manner desired, so that its butt-end will abut against the meeting ends of the rails 3 and 4, the rail 3 being the inner rail of the main track,wl1ile the rail 4 is the inner rail of thesiding in connection with which the switching-rail is located, and these rails 3 and 4 are sojoined together that their end 7 is of the same size as that of a single rail. The point 8 of the rail 2 is beveled off from each side, so that the end of the rail will fit snugly against the outer rail of the siding, as shown in full lines in Fig. 1, or will fit against the rail 5 of the main track.

In order that the rail 2 may be held from spreading,I provide two'sets orseries of stops, one set of stops being designated by the numher 9, while the other is designated by the number 10, the series marked 9 being to pre vent the spreading of the rail when the main track is op'en,and the series marked 10 being employed to hold the rail when it is moved to a position to open the way to the siding.

In connection with the rail 2 I providea rail, 11, that is placed along the outside of the rail 5 of the main track, said rail 11 resting Serial No. 206,124. (No model.)

I on rollers 12, that are arranged at about right angles to the length of the rail which they support. This rail 11 is placed so that its base faces toward the outer side of the rail 5, and is connected to the rail 2 by a number of tierods, 13, there being as many of these rods employed as may be deemed necessary. The rail 2 rests in jaws 14, formed in the extending ends of the rods l3,while the other ends of the rods pass through the rails 11,and are heldin place by nuts 15. One end of the rail 11 isheld to place by a staple, 20, while the other end is connected to the lever 17 of a switchstand, 16, by means of a connecting-link, 18, so that as the lever 17 is thrown in the direction of the arrow the rail 11, and with it the rail 2,will be moved to the position shown in dotted line. As the rail ll is moved as described, it will slide edgewise, and hence the need of providing the rollers 12.

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

1. In a switch, the combination, with the rails 3, 4, 5, and 6, of the switch r-ail 2, having its end abutting against the ends of the rails 8 and 4, the rail 11, outside of the rail 5 of the main track, the tie rods 13, connecting the rails 2 and 11, an operating-lever, 17, and a rod, 18, connecting the lever to the rail l1,sub stantially as herein shown and described.

2. In a switch, the combination, with the rails 3, 4, 5, and 6, the meeting ends of the rails 3 and 4 being united, as described, of a switch-rail, 2, a rail, 11, supported by rollers 12, rods 13, engaging with the rails 11 and 2, a switch stand and its lever,and a connectingrod extending from the lever ot' the switchstand to therail 11, substantially as described.

two series of stops, as 9and 10, rods 13, formed with jaws 14, which engage with the switching-rail, a rail, 11,'to which the rods 13 are secured, a loop, 20, rollers 12, and a switchthrowing mechanism, substantially as described.
