RAIL-JOINT CHAIR.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed September 19,1906. Serial No. 335.299.

To 0//// whom it 772/6112] concern:

Be it known that I, GEORGE \VAsrnNeToN STROTHER, a citizen of the United States of America, residing at Jenifer, in the county of Talladega and State of Alabama, have invented new and useful Improvements in Rail-Joint Chairs, of which the following is a specification.

This invention relates to rail joint chairs and one of the principal objects of the same is to provide means for securing the meeting ends of a pair of railway rails which will dispense with the usual bolts which pass through the fish plate and through the web of the rail.

Another object is to provide simple and eflicient means for firmly uniting the meeting ends of railway rails without the use of through bolts and which will effectively prevent the spreading or creeping of the rails.

These and other objects are attained by means of the construction illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of the meeting ends of two railway rails united by means of my rail joint chair. Fig. 2 isa plan view of the chair removed from the rails. Fig. 3 is a sectional view on the line 3-3, Fig. 1. Fig. 4 is a detail plan view of one of the fish plates or splice bars, partially broken away.

Referring to the accompanying drawing for a more particular description of my invention, the numerals 1 designate the meeting ends of the railway rails and 2 are the ties located at a short distance from the ends of said rails. The splice bars 3 each consist of a vertical flange provided with inwardly extending longitudinal beads 1 designed to bear against the under surface of the tread portion of the rails and at the sides of the upper portion of the web of the rails, as shown in Fig. 3, a similar bead 5 bearing upon the web of the rail at the point where it joins the base of the flange portion. Between the beads i and 5 a space 6 is provided. When desired through bolts may be used for connecting the splice bars 3 to the web of the rails and when so used, the bolts will crowd the upper bead 4 and the lower bead 5 against the under surface of the tread portion of the rail and against the top of the flange portion thereof, as will be obvious. The inclined flanges 7 of the splice bars fit the outer surface and outer edge of the rail flange and are provided with marginal spike recesses 8, as shown in Fig. 4.

The rail chair consists of the two oppositely inclined flanges 9, said flanges adapted to fit the upper surface of the flanges 7 of the splice bars, as shown in Fig. 3, and to provide a space between said flanges for the meeting ends of the rails and for the lower portions of the splice bars 3. At the central portion of the rail chair the flanges 9 are enlarged, as at 10, and connecting said enlarged portion is a cross brace 11 which extends from the lower portion of the flanges 9, said cross brace fitting and filling the space between the two ties 2,2, so as to firmly hold the chair against slipping endwise of the rails. Spike apertures 12 are formed in the outer edges of the flanges 9 to accommodate the spikes 13 and 14, said spike apertures being arranged out of'alinement, as shown in Figs. 1 and 2. The spike apertures S in thesplice bars 3 are adapted to register with the spike apertures 12 through which the spikes 14 are driven and the result of this arrangement secures the splice bars and rail chair against sliding longitudinally and also prevents the spreading of the rails laterally, while the cross brace 1 l firmly holds the parts from shitting or moving in either direction, longitudinally of the track.

From the foregoing it will be obvious that by means of a rail joint chair and splice bars made in accordance with my invention, the meetingends of the rails may be firmly held together without the use of through bolts and that in case it is desired to use the through bolts, the splice bars will be rigidly braced a ainst the lower surface of the tread portion oi the rail and the upper surface of the base flange thereof to provide a strong, rigid, durable and eflicient rail joint.

Having thus described the invention, what I claim is:

The herein described rail splice consisting of splice bars disposed upon opposite sides of the rail joint, said splice bars each being provided with a longitudinal rib to bear against the web of the rail at a point under the head of said rail, and a rib to bear against the web of the rail at the top of the base flange thus providing a space between said ribs at each side of the web of the rail, and a rail chair consisting of enlarged central portions and oppositely disposed flanges to rest upon the upper surface of the splice bars, a cross brace i In testimony whereof, I a'HiX my signature connecting said enlarged 1clentral polrtipn, said in presence of tWo Witnesses.

cross brace 1 in in a orizonta p ane to 7 1 span the spacg be tween the ties at the joint of GEORGE WASHINGTON STROLHER' the rails, and spike apertures provided in the WVitnesses: outer edges of said flanges, essentially as de- 5 T. M. DRAPER, scribed. l WV. D. SMYTI-I
