Application esca ism 1,1917. Seriai no. 162,109.

To all whom it may concern Be it known that I, ELIJAH N. KING, a citizen of the United States, residin at Hargett, in the county 01 Estill and tate oi Kentucky, have invented new and useful Improvements in Switchdtails, of which the tollowing is a specification.

This invention relates to railway switches.

The primary object is to provide siding rails which may be secured at any point in the main track rails for the purpose of providing a temporary switch or siding, it not being necessary to interfere in any way with the main track rails in the positioning and use of the switch.

A further object of the invention is the provision of temporary siding rails which are so formed as to engage or fit the side portions or fishing spaces of the main track rails in order to aid in holding in position the said siding rails.

A still further object is the provision of V temporary siding rails which are provided with tapered ends overlying the heads of the main rails, so as to provide a gradual elevation of the siding rails to permit their passage over the top of the main rails.

With the above and other objects in view the invention consists of the following novel combination and arrangements of parts hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure l is a plan view of a main line track equipped with temporary siding rails constructed 111 accordance with the invention;

Fig; is an enlarged cross sectional view taken through one of the main track rails and the adjacent engaging end of the siding rail.

Fig. 3 is a detailed perspective view of the tapered end of the siding rail; and

Fig. "4: is a detailed perspective view of the clamp.

The invention in its practical form comprises a pair of grooved siding rails 10, which are adapted to be temporarily secured to the main track rails 11 by means of suitable clamping devices 12.

The siding rails are formed at thelr ends which engage the main track rails with an enlarged portion 18 the bottom of which is adapted to lie flush with the base flanges of the main track rail. This enlarged end 13 of substantially L-shape in cross section, 7 that portlonwhiclrengages thesldeot the main track rails being formed with a 1011- gitudinal rib 141, which is adapted'to fit snugly within the fishing spaces of the main track rails and to aid in holding the siding rails thereto by preventing upward movement. As illustrated in Fig. 3 the end of this portion of the sidingrails is finely tapered so as not to present any obstruction to the flanges of the car' wheels. The top portions 15 of the sidingrails is also tapered and is adapted to fit and overlie the head of the rails 11 as shown. This forma tion provides a groove 16 between the overlying portion 15 and the rib 14; of the siding rails, the grooves 16 snugly fitting the heads of the main track rails. The overlying portions 15 as before stated are tapered in order to provide a gradual elevation of the heads of the siding rails above the main track rails, this elevation enabling the laying of the siding rails over the said main track rails so as to render it unnecessary to interfere with the main track rails.

For the purpose of securing the siding rails to the main track rails there is employed the clamp 12, this clamp being formed with a notch 17, which includes the oppositely located recesses 18 for engagement with the base flanges oi the main line and siding rails. As the enlarged portion 13 of the siding rails is tapered, this clamp may be driven upon this tapered portion so securing means holding the siding rails in" position until their removal is desired. By

- constructing the siding in the manner shown it is unnecessary to in any way interfere or tear up any portion of the main tracki'ails,

so that the siding may be removed and the main track remain 1n 1ts former condltlon.

Having described the invention, what is claimed, is

In a railway switch, the combinationwith main track rails, of siding rails each provided with tapered ends adapted to engage the main track rails, said tapered ends each including longitudinal ribs adapted to fit within the fishing spaces of the main track rails, a tapered flange adapted to overlie the head of one of the main rails, said flange andrib-defining a groove to snugly fit the flange and portion of the side rail extending over the head of the main rail defining a longitudinal groove, a clamp surrounding the lower portions of the main track rail 10 other .end engaging the fishing space upon 15 the opposite side of the main track rail.

In testimony whereof I aflix my signature.

ELIJAH N. KING.
