RAILWAY SWITCH.
APPLICATION FILED APR.16. I917.
Patented Feb.12,1918.
In ve ni'o r Ed Ward Cfiamfiem,
flttorn ya EDWARD C. BACHFIELIQOF INDIANAPOLIS, INDIANA.
RAILWAY-SWITCI-L Application filed April 16, 1917.
To all whom it may concern:
Be it known that I, EDWARD C. BACH- rinLn, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Railway- Switches, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to an improved railway switch and comprises a peculiar railway tie in which one portion constitutes the fixed member to be embedded in the base or bed of the railway and the other the movable member on which the switch rails are mounted.
In the accompanying drawings, Figure 1 is a plan view of a section cf a railway embodying my invention; Fig. 2 is a detail transverse section of the tie itself; and Fig. 3 is a side view of the tie and an end view of two rails.
My tie is composed of a lower member 1 designed to be secured to the road-bed in any desired manner and to be stationary and firm, and of an upper movable member 2 designed to be shifted laterally of the road-b3d or lengthwise with respect to the other member 1. These two members are connected by a slidable joint of any desired character, preferably a dovetailed joint, as shown at 3 in Fig. 2.
The lower member of each tie being embedded and secured to the road base, the upper member receives the rails. As many of these ties are employed as will be suitable for the length of the switch-rail, that is, the rail which is shifted from alinement with the abutting rail to alinement with the siding rail. These switch-rails I indicate at 4 in Fig. 1 and they are to be shifted laterally from alinement, say with the line rails 5 to alinement with the siding rails 6. The manner of securing the rails to the ties may be that commonly employed or may be that special means set forth in my application filed April 16th, 1917, Ser. No. 162,243, for improvements in railway ties, in which a special seat 7 is formed in the tie or tie block to receive the rail base and a special clamp 8 is employed for clamping and securing the rail in such seat. I have shown in the present drawings this special type of tie and seat with its securing clamp, but it will be understood that the feature of my two member tie is independent of this par- Specification of Letters Patent.

Serial No. 162,241..
ticular means for securing the rails to the ties. I prefer this means but do not confine myself to it.
Returning to Fig. 1 again, it will be seen that one of the slidable sections 2 of the tie is connected to a pitman 9, in turn secured to a crank arm 10 on a switch shaft 11 operated by a lever 12. When the switchrails are to be shifted from one position to another these switch devices are operative and the upper members of the ties will slide on the lower members and thus move with the switch-rails.
In this way the relation of one switch rail to the other is not disturbed and is always maintained, which insures the equal movement of both switch rails in adjusting them into alinement with the other rails. Again, this arrangement affords a smooth and easy adjustment of the switch rails because the members of the tie will readily travel the one on the other. To facilitate this 1 provide for lubrication between the sliding surfaces. At 13 and 1a I indicate caps which fit over grease orifices 15 shown particularly in Fig. 2. Lubricant is thus introduced to' the sliding surfaces, facilitating the movement of the one tie member on the other.
By the construction described I have provided means whereby the permanent connection of the rails with the tie is not disturbed or strained by the adjustments of the switch rails, and whereby such adjustment is easily and smoothly made.
While I have shown and described one embodiment of my invention it will be un derstood that the same has been chosen for the purposes of illustration only, and that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
1. In a railway structure, the combination, with railway ties, each comprising a fixed base member and an upper member slidable longitudinally thereon, and connected thereto by a dovetailed joint, of rails above said upper members, and clamps mounted on said upper members and engaging said rails, and hand operated members to adjust the upper members whereby to move said rails to and from switching position.
2. In a railway structure, the combination, with a series of railway ties each composed of a lower fixed member and an upper slidable member, the members being interconnected by a dovetailed joint, of rails secured to the upper members, and devices to shift the upper members back and forth on the lower members. i
3. In a railway structure, the combina tion, with railway ties, each comprising a fixed base member having a flat upper surface and an upper member, said two members being connected by a dovetailed joint per- V tudinally along said lower members, of rails above said upper members, clamps mounted in the upper members and outside of and engaging said rails, means for lubricating the sliding abutting surfaces of said upper and lower members, and hand operated means for sliding said upper members, whereby to move said rails to and from switching position.
In testimony whereof, I affix my signature.
