RAILWAY-TRACK CONSTRUCTION.

Specification of Letters Patent.

Patented Apr. 5, 1910.

Application filed January 10, 1910. Serial No. 537,133.

To all whom it may concern:

Be it known that I, JosnrI-I W. BLOWER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Railway-Track Construction, of which the following is a specification My invention relates to the improvement of railway track construction and the objects of my invention are to provide a simple, inexpensive and yet durable track construction which may be particularly useful in mines and similar places where rapid and inexpensive track building is desirable. These objects I accomplish in the manner illustrated in the accompanying drawing, in which- Figure 1 is a view in perspective of a section of track having my improved construction, Fig. 2 is a side elevation of a portion of one of the tie members taken at the point of intersection with a track rail, Fig.

is a plan View of the track rail and tie connection, Fig. 4 is a transverse section on line 00-40 of Fig. 2, Fig. 5 is a plan view of the track rail clamp which I employ in the manner hereinafter described, and, Fig. 6 is a detail View in perspective of a key or wedge which is employed for looking a tie and track rail in connection with each other.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention, I employ transverse track ties 1 which as indicated in the drawing, are preferably formed of track rail sections of the usual T-form, although it is obvious that other forms of ties may be employed. At the points where the track rails 2 bear upon the ties, I form in the upper surface of each of said ties a shallow transverse recess 1 each of said recesses being of such width as to permit of the seating therein of the base flange 2* of the usual track rail.

3 represents a rail clamp which comprises a metallic bar which is bent in the form of an oblong frame, the ends of the bars being joined and the frame thus formed having its ends bent upwardly and inwardly to the substantially hook forms shown at 3 and 3 As shown in the drawing, the clamp end 3 extends upward to a greater height than the end 3". It will also be seen that the parallel side members 3 of the clamp are bent in ward toward each other.

Prior to the seating of the base of a track rail in the recess 1 of the tie, one of the clamps 3 is slipped endwise on to the head or tread of the tie rail until the upturned members 3 3 are on opposite sides of the recess 1*. In slipping the clamp on to the tie, it will be understood that the inturned parallel sides 3 of the clamp, will embrace opposite sides of the upper portion of the tie rail web, while the upturned hook-like ends of the clam will embrace the flanged head of the tie rail. The clamp having thus been positioned on the tie rail, the track rail 2 has its base portion inserted between the upturned end members 3 and 3 of the clamp and seated in the tie recess 1. The clamp is now moved on the tie until its inturned end 23 engages the upper side of the track rail base flange on one side of the track rail, after which an angular tapering wedge body such as is indicated at 4, is driven small end first, between the web of the track rail and the higher inturned end 3 of the clamp until the rail is firmly bound in place. It will be noted that the angular form of the wedge or key body 4, is such as to permit of its thicker or higher portion engaging the longitudinal recess in the track rail which lies between the head and base thereof, while the outer and shallow portion of the wedge is engaged by the inturned end?) of the clamp.

By the construction and operation described, it will be observed that a comparatively simple track rail construction is provided, by means of which a track for the support of cars in mines and similar places, may be readily constructed at a comparatively small expense. I

From the foregoing description, it will be seen that simple and eilicient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claim.

What I claim, is-

In a track rail construction, the combination with a transversely arranged tie of substantially I-shape in cross section and a correspondingly shaped track rail adapted to have its base portion bear upon said tie, of a clamp comprising an oblong frame body the other side of'the track railand'tlie corhaving its longer parallel side portions bent responding inturned end of the clamp. 10 inward and its end portions bent upward In testimony whereof I afl iX my signature and inward, said clamp body adapted to in presence, of. two witnesses.
