Application filed September 14, 1914. Serial No. 863,655.

To all whom it may concern Be it known that IfWILLIAM K. ANDER- son, a citizen of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented certain new and useful Improvements in Railway-Switches, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in switches and has relation more particularly to a device of this general character of a portable type, and an object of the invention is to provide a device of this general character having novel and improved means whereby the same may be employed in connection with a fixed track-way without the necessity of interfering in any Way ivith the rails of the fixed track-way.

The invention consists in the details 01' construction and in the combination and arrangement of the several parts of my improved. switch wherein certain important advantages are attained and the device is rendered simpler, less expensive and othcrwise more convenient and advantageous for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a view in plan of a section of a fixed trackway illustrating a switch con structed in accordance with an embodiment of my invention applied thereto; Fig. 2 is an enlarged view in plan of a frog coinprised in the present einhndiment of my in vention, said frog being also shown in applied position; l ig. 3 is a view in side elevation of the frog as disclosed in Fig. 2; Fig. 4 is a sectional view taken substan tially on the line 4 4 of Fig. 1 Fig. 5 is a sectional view taken substi'uitially on the line 5-5 of Fig. 3; Fig. (9 av sec ional view taken substantially on the lino {3 4 oi Fig. 1, and Fig. 7 is a sectional view taken substantially on the line T----7 of Fig. 1.

As disclosed in the accompanying lira-w ings, It denotes the rails comprised in a fixed track-way of conventional construction having enacting in connection there with a turn-out or siding in which iscomprised a switch constructed in accordance with my invention. 1

As herein embodied, my improved switch is shown employed in connection with the siding, said siding, comprising the rail 1 disposed on the proper curvature and positioned intermediate the rails R and being immovahiy secured to the ties T and having one extren ty terminating in close proximity to one of the rails R while the opposite extremity is projected within one of the terminal rec-e or slots 2 produced in the angular portion of the frog comprised in the present embodiment of my invention, while a rail comprised in the siding has an ext 'emity disposed in the second term-L nal recess or slot 2 and the extremities of the rails l and S are locked or claniped within the respective slots or recesses 2 through the medium of the wedges 4. disposed through the portion of the frog below the rail, as is believed to be clearly iliust rated in Fig. 5 of the drawings. The intermediate or straight portion 5 of the frog is provided with a longitudinally disposed groove 6 adapted to receive one of the rails It, the inner side wall 7 of said groove 6 being formed so as to overlie the adjacent flange of the rail while the opposite wall of the groove is recessed as at 8 to receive the wedges 9 whereby said frog is effectively clamped to the rail As is believed to be self-evident, the frog hereinbeforc set forth may be applied with convenience and facility and. without the necessity of cutting or otherwise injuring the rail ll.

The second rail #3 comprised in the siding terminates at one extremity in close proximity to the rail it with which the frog coacts and has its inner extremity provided with the wing or tread 10 movable in a verplane around a horizontal axis 11 proecting in continuity Wlllil'illl ball of the rail 55 and further supported in its outer ex tiemity hy the brackets 12 or the like suitably anchored to cc in of the ties T. As is particularly shown in Fig. 6, the block B is provided in its upper surface with the transverse groove (3 adapted to receive the base of a. rail l, one side 7 of the groove being formed so as to overlie the adjacent Hangeof the rail While the opposite Wall of the groove is recessed, as at 8, to receive a wedge 5) whereby an etlcctive connection created between the liloelg B and the rail 8, as is thought to heelearly apparent to those skilled in the art to which my present invention app rtains. It is to be understood that the block B is adapted to be slipped over the end of the rail with which it coacts.

The wing or tread 10 has its forward extremity enlarged transversely as indicated at 14 in Figs. 1 and 6, to overlie the adja-.

cent portion of the immediate rail R, and such laterally increased portion" is provided with a depending channel member 15 to receive the flanges of the wheels of the stock passing over the rails B so as to cause the same to jump the rails R and be received upon the rails S. The wing or tread member 10, can be applied in an operative or in-v operative position relative to the coacting rail R in a convenient manner.

The inner extremity of the inclined portion 3 of the frog is provided along its inner edge with an upstanding flange 16 for the guidance of the wheels of the rolling stock across the rail and it is to be observed that the upper face 17 of the inner end of the inclined portion 3 of the frog is positioned in a plane above a tread of the rail R to be bridged, except the inner portion 18 thereof, which is inclined downwardly so that the contact of the wheels of the rolling stock thought to be obvious that a switch con structed in accordance with my invention is of an extremely simple and comparatively inexpensive nature, and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and by reason of the effectiveness with which it performs its functions, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the-precise arrangement and formation of the several parts herein shown of my invention in practice.

I'claim:

1. A railway switch including a tread arranged for swinging movement in a vertical plane from one of the rails of a siding to overlie the rail of a main track to provide for. the passage of the car wheels above the plane of the main rail, the forward extremity of the tread being enlarged transversely to overlie the rail, the free longitudinal margin of the transversely enlarged portion being provided with a depending channel member.

2. A railway switch including a tread arranged for swinging movement in a vertical plane from one of the rails of a siding to overlie the rail of a main track to provide for the passage of the car wheels above the plane of the main rail, said tread being provided with a depending channel member adapted to overlie the inner side of the rail.

3 The combination with a main trackway, of a siding removably secured to one of the rails thereof, a rail secured to one extremity of the frog and interposed between the rails of the main track on the proper curvature and terminating in close proximity to the opposite rails of the maintrackway, a siding rail secured to the frog, a second siding rail terminating in close proximity to the rail of the main track with which the frog is engaged, and a tread pivotally supported by the last mentioned rail of the siding and adapted for movement in a vertical plane to overlie the adjacent rail of the main track, the forward extremity of the tread being enlarged transversely to overlie the rail, the free longitudinal margin of the transversely enlarged portion being provided with a depending channel member. 4. -A switch of the type described including a frog arranged to form a seat for a main track rail, havin arranged laterally of the seat, receiving t e said rail, elevated portions to provide for the passage of the wheels of the car in a. plane above said main track rail, said shoe having a flange contiguous to one. end of the rails of said siding, the o posite portion of said shoe being provided with a shoulder to guard the car Wheel in its passage across the main rail onto a rail section extension, and arranged about in alinement with the inner end of one of the said siding rails.

In testimony whereof I hereunto aflix my signature in the presence'of two witnesses. WVILLIAM K. ANDERSON. YVitnesses:
