RAIL-CHAIR.

SPECIFICATION forming part of Letters Patent No. 449,570, dated March 31, 1891.

Application filed April17, 1890. Serial ITox 348,288. (No model.)

1'0 aZZ whom it may concern.-

Be it known that 1, WILLIAM A. PEARSON, Jr., a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Rail-Chair, of which the following is a specification.

The invention relates to improvements in raiLchairs.

The object of the presentinvention is to provide a simple and inexpensive rail-chair in which the parts can be readily tightened to clamp the rail, and in which the latter will be securely held.

A further object of the invention is to improve, simplify, and cheapen the construction of rail-joints.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described,- illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l is a perspective view of a rail-joint constructed in accordance with this invention. Fig. 2 is a central transverse sectional view, one of the rails being shown in elevation. Fig. 3 is a detail view of the chair.

fish-plates S are secured to the web 9 of the rail by bolts 10, which pass transversely through the fish-plates and the web of the rail in the ordinary manner, and the said fish-plates are provided with horizontal flanges 11, which have their outer edges inwardly beveled and adapted to fit against the inner faces of the flanges 4 and conform to the inclination thereof, whereby when the bolts are tightened by nuts 12 the fish-plates will be forced against the rails 1 and will securely clamp the same and hold them fast to the chair. The heads of the bolts 7 are arranged beneath the chair, and the nuts are arranged on top of the horizontal flanges 11 of the fish-plates, thereby affording easy access to the nuts and enabling the bolts to be readily tightened.

It will readily be seen that the rail-joint is exceedingly simple and inexpensive in construction and is adapted to be readilyv adjusted and tightened, and is capable of securely clamping the rails and holding them fast to the chair; and it will also be seen that the parts may be readily separated when it is desired to remove the rails or to supply new bolts.

What I claim is- The combination, with the rails, of the chair 2, having the recess to receive the rail and provided along its edges with the vertical flanges 4, having their inner opposed faces beveled or inclined outwardly, the fish-plates 8, provided with horizontal flanges 11, having their outer edges inwardly beveled and com forming to the inclination of the faces of the flanges 4, the horizontal bolts 10, passing through the fish-plates and the webs of the rails, and the bolts 7, passing through the chair, the bottom flanges at both sides of the rails and the fish-plates and adapted to force the latter against the rails and securely clamp the same, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

WILLIAM A. PEARSON, JR,
