TRACK-JOINT.

Specification of letters Patent.

Patented Oct. 11, 1910.

Application filed February 21, 1910. Serial No. 545,117.

To all whom it may concern:

Be it known that I, HOUSTON R. ANDER- soN, a citizen of the United States, residing at Chattanooga, in the county of Comanche, State of Oklahoma, have invented certain new and useful Improvements in Track- Joints; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to rail joints and its principal object is to provide a rail joint of novel construction wherein a single fishplate is used to securely hold the two ends of a rail in position and strengthen and support said ends between the ties, said plate thus acting as a species of chair.

With the above and other objects in view, as will be hereinafter apparent, the invention consists in general of a novel construction of fish-plate and chair designed to connect and support the abutting ends of a pair of rails.

The invention further consists in certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically set forth in the claims.

In the accompanying drawings, like charactors of reference indicate like parts in the several views, and :--Figure 1 is a perspective view of the improved chair showing one rail in position on the plate. Fig. 2 is a side elevation of such a fish-plate. Fig. 3 is a section on the line 33 of Fig. 2. Fig. 4 is a section on the line t4 of Fig. 3.

The numeral 10 indicates the base of the chair and this base is of suflicient length to bridge two adjacent ties of the track. At each of the longitudinal edges of the base 10 there is provided an upstanding flange 11 and the distance between these flanges is such that the foot of a rail will closely fit within the space thus provided. Extending up from the base 10 and formed integrally therewith are looking members 12 each having an end 13 which extends longitudinally in spaced relation to the base 10, the body and end of these members being at right angles to each other. These ends 13 thus overhang the base and the under side extends substantially parallel to said base while the depth of the ends 13 is such that when the rail is in position the ends completely fill the space between the head and the members 12 and their ends 13 are ar ranged in pairs with the ends extending in the same direction, and the members 13 and their ends are spaced, in each pair, at such distance as to closely engage the web of the rail.

The rail end is preferably thickened in the foot so that the top and bottom surfaces of the foot are parallel. The end of the rail is here indicated at 14 while the thickened portion of the foot is shown at 15. On each side of the rail web 16 there is formed a slot 17 which extends through the foot of the rail and is of a length equal or slightly greater than that of one of the members 12 and its end 13. This slot is also substantially equal in width to the thickness of one of these members.

In assembling the device the ends of the rail are brought together in the usual manner and the chair moved up from beneath the ends in such manner that the members 12 pass through the slots 17 The chair is then moved longitudinally of the rails so that the feet 15 of these rails engage beneath the overhanging ends 13. As an alternative method of assembling the rails may be placed one after the other on the chair and moved so as to bring their feet beneath the ends 13. It is to be noted that one pair of the members 12 have their ends 13 so arranged with relation to the slots 17 that the ends 13 of this pair project beyond the rail end, this being clearly shown in Figs. 1, 2 and 4. The purpose of this is vto provide against lateral displacement of the extremities of the rails with reference to each other as well as to prevent vertical displacement of said rails.

In order to hold theparts in position after assembling, the rails are provided with spike receiving notches 18 at their edges while the chair is in like manner provided with spike receiving openings 19 adapted to register with the notches when the rails and chair are assembled. After the assembling operation above described, spikes are driven through these openings and notches and serve to prevent longitudinal displacement of the chair with reference to the rails as well as to hold the rails in position on the ties.

There has thus been provided a simple and eificient device of the kind described and for the purpose specified.

Having thus described the invention, What is claimed as new,is:

1. In a rail joint, the combination With a pair of abutting rail ends each having a pair of slots extending through its foot, said slot-s lying one on each side of and adjacent to the Web ofeach rail end and terminating opposite each other, said rail ends each having spike notches at the edges; of a chair having a base portion provided with upstanding flanges to engage against the longitudinal edges of the rail feet, upstanding members formed on said base and extending through said notches, said members being arranged in pairs, ends formed on said members and all extending in the same direction, said ends being of such depth as to fill the spaces between the heads and feet of said rails, one pair of said ends overlapping one rail end and engaging the other, and said chair having spike openings in its base registering with said spike notches.

2. In arail joint, the combination with a pair of abutting rail ends each having a, slot on each side of its Web; of a chair having a base portion provided with flanges extending along the sides to embrace the feet of said rail ends, upstanding members formed on said base and extending through said slots, ends formed on said members engaging between the heads and feet of the rails, and means to prevent longitudinaldisplacement of said chair on said rails.

3. A chair for rail joints comprising a. base portion provided With upstanding flanges extending along the side edges, spaced pairs of upstanding members formed on said base, the members of each pair being spaced apart a suflicient distance to re ceive the Web of a rail between their inner faces, extensions formed on said members and all extending'in the'same direction, said extensions being spaced from the base and parallel thereto, and said chair having spike openings through the base in immediate juxtaposition to the upstanding flanges.

In testimony whereof, I aflix my signature, in the presence of tWo Witnesses.-

HOUSTON R. ANDERSON.
