TH REE-WAY RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 536,715,dated April 2, 18S 5.'

Application iiled February 13, 1895. Serial No. 538,762. (No model.)

` To @ZZ whom it may concern,.-

Be it known that I, JAMES D. BAILEY, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Three-Way Railway- Switches; and I ldo hereby declare that the following'is a full, clear, and exact description of the i-nvention, which will enable others skilled. in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form part of this specification.

My present invention relates to improvements in threeway split switches.

In the drawings which accompany and form apart of this specification and in which similar numerals of reference refer to corresponding parts in the several views, Figure 1 shows a plan view of the switch closed. Fig. 2 shows the switch in the first shift. Fig. 3 shows the switch in the position of the second shift Fig. 4 is a side View. Fig. 5 shows a cross section taken at the side of the shifting-bar with the rails corresponding in position to Fig. 1. Fig. 6 shows a similar section corresponding to Fig. 2. Fig. 7 shows a similar section corresponding to Fig. 3. Fig. 8 shows a cross section including the springs. Fig. 9 shows a modified form of construction.

Referring to the reference Iigures in a more particular description, 1 and 2 indicate` stationary rails secured to ties as 3 in the usual manner, and which rails diverge at the switch substantially as shown. Between the stationary rails at the point of divergence are located the four movable pointed split rails 4, 5, 6 and 7. The points of the rails 5 and 7 lie back of the points of rails 4 and 6. The rails 5 and (i are secured to the shifting-bar 8 by clamps 5 and 6a respectivelygso as not to be movable in either direction along the bar. The rails 4 and 7are independent of the shifting-bar to move in one direction, but are moved with the shifting-bar in the other direction. This movement, so far as rail 4 is concerned, is caused by the hooked shoulder projection 9, and as to rail 7, by as similar projection l0 from the shifting-bar.

Instead of the projections 9 and 10,asleeve block 11 having fingers for engaging the rail, may be provided, which block willslide freely in one direction on the shifting-bar and be operated on the other by a fixed collar or shoulder piece 12.

For operating the switch rails 4 and 7 in the opposite direction from that to which the shifting-bar is adapted to operate them, there are provided springs 13 and 14. These springs operate from a fixed support 15 against the sliding chairs 16 and 17, respectively, whichA are secured to the rails 4 and 7. The

springs are mounted on a rodlS which holds noted, however, that when the switch is ady justed to the position shown in Fig. 1, which is the normally closed position, all the rails are held positively and the switch cannot be maliciously displaced without breaking the mechanism. In this position none of the rails are held only by springs, so that by the use of a bar they could be sprungandblocked in dangerous position.

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

1. The combination in a three way switch, of'two diverging fixed rails, four intermediate pointed rails, a shifting bar to which the two middle movable rails are immovably secured, and having shoulders engaging from the outer n sides only, the two outer movable rails and springs acting against the outer movable rails from the inner sides, substantially as set forth.

2. The combination in a switch of two di- Verging rails, intermediate movable split rails 4, 5, 6 and 7, a shifting-bar to which rails 5 and 6 are fastened, and having means for engaging and moving rails 4 and 7 from the outer sides only, and a spring operating against the inner sides of rails 4 and 7, sublo stantialiy as set forth.

In witness whereof I have afixed my signature in presence of two witnesses.

JAMES D. BAILEY.
