SAFETY-SWITCH.

$PECIFICATION formingpart of Letters Patent No. 376,177, dated January 10, 1888.-

Application filed January 13, 1887, Serial No. 221,206. (No model.) I

To Ml whom, it may concern.-

Be it known that 1, JOHN B. BATT, of Williamsville, in the county of Erie and State of New York, have invented new and useful Improvements in Safety-Switches, of which the following is a specification.

This invention relates to that class of safetyswitches in which the switch'rails are moved automatically .to the proper position by the wheels when the latter approach the free ends of the switch-rails on a track for which the switch is misplaced.

My invention has for its object to produce a simple and durable switch of thiskind, which guides the wheels securely and which is easily kept in order.

My invention consists of the improvement, which will be hereinafterfully set forth, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a top plan view of my improved switch set for the main track. Fig. 2 is a similar view, showing the switch set for the side track. Fig. 3 is a Vertical cross-section in line a: m, Fig. 1.

Like letters of reference refer to like parts in the several figures.

A A and B B represent the stationary rails of the main track.

' O 0 represent the movable switch-rails pivoted near the ends of the rails A A.

D Drepresent the rails of the siding ar; ranged alongside the main rails B B and terminating in line with the same.

E E represent guard-rails arranged on the inner sides of the switch-rails O O, and rigidly secured thereto by bolts 6 and intermediate blocks, f, or other suitable means, so as to move with'the switch-rails. The latter and the guard-rails are supported on plates upon the ordinary cross-ties and connected to a crossbar, g, which is operated by a shifting The front portions, h h, of the guardrails E E extend forwardly beyond the ends of the main In the position of the parts represented in Fig. 1 the switch is set for the main track and the guard-rail E rests with its curved front portion, h, against the inner side of the side rail,D. WVhen a locomotive or car approaches the switch on the side track, D D, for which the switch is misplaced, the wheel running on the side track, D, strikes with its flange running on the main rail B strikes with its flange against the front curved portion, h, of the guardrail E, and moves the switch-rails and guard-rails laterally to the position rep resented in Fig. 1, thereby setting the switch for the main track.

I am aware that it is not new to connect the guard-rails with the switch-rails in such manner that a wheel striking the projecting curved end of the guard-rail will shift the switch, as in Patent No. 267,308, November 7, 1882, and that switch and guard rails have been provided with lateral flanges, as in Patent No. 175,287, March 28, 1876, and I do not claim such construction.

I claim as my invention- The combination, with the main rails B B and side rails, D D, of the movable switchrails O O, guard-rails E E, provided with inwardly-curved front portions, 71 h, blocks f, arranged between the guard -rails and the switch-rails, and bolts 6, whereby the guardrails and blocks are rigidly secured to the switch-rails, substantially as set forth.

\N'tness JOHN B. BATT.
