RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 424,968, dated April 8, 1890.

Application filed October 17, 1889. Serial No. 327,355. (No model.)

To ctZZ whom it may concern.-

Be it known that I, LYMAN M. GARFIELD, of Xenia, in the county of Greene and State of Ohio, have invented certain new and useful Improvements in Railway-Switches, of which the following is a specification.

My invention relates to railway-switches, and its object is to furnish such an arrangement of the movable rails and their operating parts that the movable rails may be brought into such connection with the stationary rails by the same set of switch-irons or bridles and by one throw of the switchlever as to make a continuous main track and two sidings on one side of the main track, or a continuous track of a main track and siding on either side of the track, or two continuous tracks composed of the main track and a siding on one side and the other composed of a main track or siding on the other side.

In the accompanying drawings, Figure 1 is a diagram illustrating the main track con: tinuous or unbroken and two sidings leading out from the main track, and both sidings on the same side of the main track. Fig. 2 illustrates the positions of the diiferent tracks when the switch has been thrown to connect the main track 011 the left with the siding on the right. Fig. 3 illustrates the positions of the different tracks when the main track on the right is connected with the siding on the left. Fig. 4 illustrates the main track continuous or unbroken and two sidings leading outward from both sides of the main track. Fig. 5 illustrates the positions of the different tracks when the switch has been thrown to connect the main track on the left with the siding on the right and the main track on the right with the siding on the left.

Referring to Figs. 1, 2, and 3, A A are the parallel stationary rails of the main track. B B are the parallel stationary rails of the siding. O O are the movable rails of the main track. ing, and a b c d are the adjacent ends, respectively, of the rails A, B, O, and D.

The movable rails O O and D D are all connected by cross-bars E E, and are all adapted to slide or swing laterally in the usual manner, so that by joining the adjacent ends of D D are the movable rails of the sidthe stationary and movable rails the tracks will be continuous. \Vhen the tracks are in the position shown in Fig. 1, the ends a and 0 will be joined, the main tracks A and C will be continuous and unbroken, and the two sidings B and D, which diverge from the main tracks in opposite directions, will be connected at their converging ends I) and d. This position of the parts will enable a train or car to move along the main tracks A and O or along the siding B and D from one to another. "When the switchman has thrown the movable rails so that the ends I) and c are joined and the rails of the main track 0 O are continuous with the stationary rails 13 B of the siding, as shown in Fig. 2, a train or car can move along the main tracks 0 on the left to the siding B on the right, or from the siding B on the right to the main track O on the left. When the movable rails have been thrown by the switchman so that the ends a and d are joined and the rails of the siding D D are continuous with the stationary rails A A of the ,main track, as shown in Fig. 3, a train or car can move along from the main track Aon the right to the movable siding D on the left, or from the movable siding D on the left to the main track A on the right. WVhen the tracks are in the position shown in Fig. 4, with the stationary siding E E diverging from one side of the main track and the movable siding D diverging from the other side and with the ends a and c joined, the main tracks A and C will be continuous and unbroken and the switch will be open, disconnecting the other tracks. When the movable rails have been thrown by the switchman so that the ends 6 and c are joined and the ends Cl, and d are also joined, the movable main rails C will be continuous with the stationary rails of the siding E on one side of the track, and the movable rails of the siding D on the other side of the track will be continuous with the stationary rails of the main track A, as shown in Fig. 5, and a train or car can move along from the main track O to the siding E on one side, or in the reverse direction over said tracks, or from the main track A to the sidingD on the other side, or in the reverse direction over said tracks.

A very important feature of my invention is that no special rails are required with which to make the switch and that after the rails have done duty as a switch they can be used in a main or side track.

lVhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the stationary rails of a main track and siding, of a sliding switch consisting of main and side rails connected together by cross-bars and mechanism for bringing the movable rails with either of their free ends opposite and adjacent to the ends of either of the stationary rails, all as set forth.

2. In combination With the rails of the main stationary track, the rails of a siding diverging from one side of the track, the sliding switch consisting of the main track 0, the side track D on the opposite side of the track from the stationary siding, bars connecting the movable rails, and mechanism for bringing the movable rails with either of their free ends opposite and adjacent to the ends of either of the stationary rails, all as set forth. In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, this 2d day of October, A.D. 1889.
