JOHN PIUS HEUER, OF PITTSBURG, PENNSYLVANIA.

RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 731,181, dated June 16, 1903. Application filed April 24, 1903. Serial No 154,084. (No model.)

To ctZZ whom it may concern:

Be it known that I, JOHN PIUS IIEUER, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification, reference being bad therein to inclined edge, forming a wedge-face, the incline or Wedge face on one member being the reverse to that on the other member. A shoe is slidably engaged with the chair and wedges against the inclined or wedge faces of the members to securely bind the same in position. y

In connection with the improved joint I may employ a spring interposed between the two ends of the rails to offer resistance to the rails when under expansion, though this con struction is not essential to" the operation of the device.

In describing the invention in. detail reference will be had to the accompanying drawings, forming a part of this application, and wherein like numerals of reference will be employed for designating like parts throughout the difierent Views of the drawings, in which Figure 1 is a side elevation of myimproved joint as applied to the rails. Fig. 2 is a top plan View of the same. Fig. .3 is a side elevation with one-half of the chair removed, showing the shoe in section. Fig. 4 is a transverse vertical sectional view through the chair, showing the rail and shoe in end elevation; and Fig. 5 is a detached detail perspective view of one member of the chair.

My improved joint is adapted to be applied member.

to the ordinary form of rails, no especial construction of the latter being required in connection with my invention. My device embodies a chair consisting of two similar members and each comprising an integral fishplate 1, flange 2, and base-plate 3. The baseplate 3 is preferably constructed of less width than the flange 2, and thus when the chair is fitted on the rail the inner edges of the two members are some distance apart, leaving a space 4 between the said inner edges of the base-plates. The outer edge of the chair member is cut away at an incline, forming a wedge-face 5, terminating at one end in a shoulder6,whichformsastop. Thesewedgefaces on the two chair members are made in reverse directionsthat is, the stop 6 is adjacent the end of one of the chair members, and the stop 6 of the other chair member is adjacent the other or opposite end of said A shoe 7 engages the chair members and embodies in its construction a base plate or member, side walls, and overlying flanges, which latter engage the upper face of the flanges 2 of the chair members. Each chair member is preferably provided with notches 8 to receive the spikes 9, which secure the rails and chair to the cross-ties. The shoe is placed on the two members of the chair, and after the rails have been inserted between the chair members the shoe is tightened by moving one chair member in one direction and the other in the opposite direction, whereby to tighten the wedge-faces of the chair members against the side walls of the shoe, it being understood that the chair members are so placed that when so moved in opposite directions to tighten the same in the shoe that when in position the ends of the chair member will be opposite. The spikes are then driven into the ties to secure the device and the rails to the cross-ties.

In practice I preferably employ a spring 10, interposed between the adjacent ends of the rails to offer resistance to the expansion of the rails, this spring straightening as the rails expand and resuming its normal shape as the rails again contract.

While I have herein shown and described the invention in detail as it is practiced by me, yet it will be evident that various slight changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a rail-joint, the combination with the rails, of a chair comprising two similar members each embodying an integral fish-plate, flange, and base-plate, each of said chair members having its outer edge cut away on an incline forming a Wedge-face, the Wedgefacebn the one chair member being reversed to that on the other chair member, and a shoe embracing the chair members and engaging said wedge-faces, substantially as described.

JOHN PIUS IIEUER.
