RAILWAY-SWITCH.

SPEGIFIGATION forming part of Letters Patent hie. 740,232, dated September 29, 1903.

A nmim filed March 18, 1903.

To all whom it may concern: D

Be it known that I, THOMAS TIMOTHY CHAL- ONER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Railway-Switch, of which the following is a full, clear, and exact description;

This invention relates particularly to improvements in railway-switches, an object being to provide a switch of simple construction that may be readily and positively shifted by a motorman or driver on a moving car.

I will describe a railway-switch embodying my invention, and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

cate corresponding parts in both the figures.

Figure 1 is a plan view of a'switch mechanism embodying my invention, and Fig. 2 is a perspective View showing the free end of the switch-tongue.

In the drawings, 1 2 designate the mainrails of a track, and 3 4: the switch-rails. Mounted to swing at the end of the switchrail 3is a switch-tongue 5, the point 6 of which is held yieldingly and normally against the main rail 1, as here shown by means of a spring 7 surrounding a rod 8, movable in a From the point end the tongue is provided with an extension 10, which is curved slightly inward, and the upper surface of this extension is below the plane of the top surface of the switch point or tongue, thus permitting the flanges of the car-Wheels to pass over said projection and onto the tonguewhen a car is to be runupon the switch. The switchtongue is movable on a plate 11, attached to the track-ties, and pivoted to this plate 11 is a shifting dog12, which engages with the projection 10 at the side adjacent to the rail 1. The top surface of this dog 12 is substantially on a plane with the top surface of the projection 10.

The shifting device consists of a shoe 13, carried by a car. This shoe is pointed atits Serial 1%, 148,561. on model.)

end, and if it is desired to pass the car along the main track the said shoe is lowered to engage with the dog 12, which will force the switch-tongue out of engagement with the main rail, permitting the car to pass. If the car is coming from the opposite direction, it is obvious that the flange of the wheel will swing the tongue inward against the resistance of the spring.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. Inarailway-switch,aswitch-tonguehaving an extension fromits point end, the top of said extension being below the plane of the top surfaceof the; tongue, and a swinging device at the side of the track-rail for engaging said extension.-

2. In a railway-switch, a switch-tongue yieldingly held against a main rail, an extension from the point end of said tongue, the upper surface of said extension being be low the plane of the top of the tongue, and a swinging dog at the side of the-track-rail for engaging with said extension.

3. In a railway-switch, a switch-tongue, a spring for holding the tongue yieldingly in connection with a main rail, an extension from the point end of the tongue and below the plane of the top thereof, a pivoted dog for engaging with said extension, and a device carried by a car for engaging with said dog to swing the tongue.

'45. In a railway-switch, a plate at one side of the track-rail, a switch-tongue pivoted on said plate, a curved extension from the free end of the tongue below the plane of the top thereof, a dog pivoted to said plate and engaging with said projection, and means for holding the tongue yieldingly against the rail.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses' THOMAS TIMOTHY CIIALONER.
