GEORGE I-f. EVANS, MEMPHIS, TENNESSEE.

BAIL-JOINT CHAIR.

To all whom it may concern:

Be it known that I, Gnoizen H. EVANS, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Rail-Joint Chairs, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in rail joint chairs and more particularly to a joint chair, wherein the use of nuts, bolts and fastening means of a like character are eliminated, the main object of the invention being the provision of a device of this character, wherein the meeting ends of two rails are securely held against lateral or longitudinal movement, without the use of bolts, nuts and fastening means of a like character.

Another object of the present invention is the provision of a rail joint chair which will possess advantages in points of efliciency and durability, is inexpensive to manufacture and, at'the same time, simple in construction and operation.

With the above and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claim. a

In the accompanying drawings forming a part of this application, Figure l is a top plan view of a rail joint chair constructed in accordance with my invention partly in section. Fig. 2 is a similar view showing the same in its open position, parts thereof being illustrated in cross section. Fig. 3 is 'a detail perspective view of one of the movable flsh plates. Fig. 4 is a transverse sectional view taken on the line 44:' Fig. 1.

Fig. 5 is a similar view illustrating the fish plates in their various positions during the removal and replacement of the rail ends; and Fig. 6 is a transverse sectional view taken on the line 66, Fig. 2.

In carrying out my invention, I provide a base plate indicated by the numeral 1 and which is formed of heavy sheet metal or cast iron and mounted transversely upon the cross ties. v This base plate 1 is provided with the spaced transverse openings 2 and 1s further provided at the ends of these openings with the longitudinally extending arcuate grooves 3 constituting knuckle seats, the

purpose of which will be hereinafter more fully set forth. Formed integral with the plate and arranged along the outer longitudinal edges of thesea-ts 3, are the retaining ribs which are provided upon their inner faces with recesses 5 closed at their ends by inward projecting shoulders 6. Movably mounted within the seats 3, are the rounded knuckles 7 which are formed upon the outer longitudinal edges of the base flanges 8 of the fish plates, said flanges extending forwardly over the base of the rail, thence in a vertical plane to provide splice plates 9 adapted to embrace the opposed sides of the webs of the rail ends to securely hold the same against lateral movement. Formed upon the inner faces of the knuckles 7, are the spaced ears 10 which are adapted to be disposed within the openings 2, when the rail ends are in their effective positions and are retained in such positionby the weight of the rail ends. The splice plates 9 are provided upon their inner faces with inwardly projecting lugs 11 adapted to engage with transverse openings 12 formed in the rail ends, so as to securely retain the rail ends against longitudinal movement. It will be noted that when the fish plates are in their efiective positions, as illustrated in Fig. 4, they will be securely held against lateral movement by means of the ribs 4 and the pressure of the rail upon the ears 10, will securely hold the fish-plates in their effective positions.

. In placing the rail ends in position. the fish plates are opened, as illustrated. in Fig. 5, the ears 10 projecting upwardly in an inclined position and the base flanges of the fish plates bearing against the upper edges of the ribs l. The rail ends are arranged between the fish plates, the bases of the rails engaging with the inner ends of the ears 10, so that when downward pressure is applied to the rail ends, the ears 10 will be pressed ends against any longitudinal movement. In,

removing the rails ends from the chair, upward pulling power is applied to the rail ends, so that the fish plates will be forc d. away from the rail ends to allow the same to be removed from between the fish plates. It
