' T 0 all whom it may concern:

Be it known that I, CHARLES F. MARTIN,

, a citizen of the United States of America,

residing at Robinson, in the cr Int-y of Crawford and State ofIllinois, have invented certain new and useful Improvements in Rail- Joints, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a rail chair particularly designed for rail joints, and the objects of my invention are, first, to provide a chair that will firmly brace the confronting ends of two rails and prevent lateral and vertical displacement; second, to obviateithe necessity of using bolts and nuts and sepa rate splice bars as a fastening medium for the confronting ends of two rails; third, to provide a strong and durable rail joint that will eliminate the jolting and bumping of rolling stock when passing over a joint; and fourth, to provide a rail joint that will pre vent vertical displacement of the confronting ends of two rails and at the same time allow for the expansion and contraction of said rails. I

The above objects are attained by a rail chair that will be hereinafter described in -detail and then claimed.

i upper sur 'aces in proximity to one end cut away sons to provide a U-shaped recess to constitute a seat. 'lhe'bottom wall of the recess is indicated by the reference character 2 and the side walls which extend vertically are indicated by the reference character -2 Mounted upon the bottom wall 2 of each recess and snugly engaging the side walls of each recess is a rail chair which is of a length as to bridge steps between the ties 1. T he rail chair comprises a base 3 substantially U-shaped in cross section and having the vertical walls 3 thereof snugly engaging thevertical walls of the recesses and of a height as to project above the upper face of the ties. Formed integral with the top of the walls 3 of the rail chair are longitudinally-extending fish plates 4 which are of a length equal to the length of the base 3. The base 3 of the rail chair is adapted to support the rails 5 and the fish plates 4 are adapted to inclo'e the base of the rails 5, abut against the webs 5 of the rails 5 and en age the lower face 5 of the tread of the rai s for supporting said tread. The walls 3 of the rail chair abut against the edges of the base of the rails 5 whereby the rails are securely maintained in position through the medium of the walls and fish-plates 4.

The outer face of each of the walls 3 of the rail shaft and the lower edges of the fish plates 4 are provided with vertically disposed notches 6 to receive spikes 7 driven in the ties 1 for holding the chair in the seats 2. The heads of the spikes 7 are adapted to extend over the fish plates 4, and prevent vertical displacement-of the chair, while the seats 2 and the shanksof the spikes prevent lateral displacement.

It will be observed that the fish plates 4 are reinforced and are of reater' width at the juncture of the rail we s with the base flanges thereof than at any other place throughout the fish plates, and this reinforced portion is adapted to prevent the webs of the rails from cracking or breaking adjacent toqthe base, flanges thereof.

Since the confronting ends of the rails 5 rest directly upon the base plate 3, and the heads of said rails are supported by the splice bars 4, a continuous tread will be provided for the rollin stock adaptcd'to pass over the rails 5, am in consequence of this continuous tread,vthe jarring and jolting of rolling stock is eliminated and'the longevity of the rails and rolling stock considerably prolonged. v

Having now described my invention what I claim as new, is

A rail joint'comprising the combination with a pair of ties, each having its upper face provided with a U-shaped recess a jacent to the end of each tie, of a rail chair mounted in said recess and consisting of a base and a pair of vertical walls, said chair substantially U-shaped in cross section and said walls snugly engagingthe vertical recess of the ties and said walls of a height as to project above the recess of the ties, said chair adapted to support a pair of rail ends and of a length as to bridge the steps between the ties, longitudinallyextending fish plates formed integral with the upper terminus ofthe walls of the chair and embracing the. bases of the rails, engaging the webs of the rails and further engaglng the lower face and the tread of the rails, said fish plates at the junction ef the .Webs and nal ed base flanges 0f the rails being reinforced, said fish plates at the junction thereof with the Walls of the chair provided with notches, said Walls of the chair having the outer faces thereof provided with notches tilining With the notches in the fish plates and spikes engaging in said ties, extending upwardly in said notches and overlapping'the longitudieral and Vertical displacement 0 said chair. In testimony whereof I a'flix my signature in the presence of two witnesses.
