-WILLIAM N. HOOPER AND THOMAS J. SUNDAY, OF CONROE, TEXAS.
RAILROAD JOINT AND CHAIR.
SPECIFICATION forming part of Letters Patent No. 756,962, dated April 12, 1904. Application filed May 21, 1903. Serial No. 158,171. (No model.)
To all whom it may concern:
Be it known that we, WILLIAM N.1Ioo1 nn and THOMAS J. SUNDAY, citizens of the United States, residing at Conroe, in the county of Montgomery and State of Texas, have invented a new and useful Railroad Joint and Chair, of which the following is a specification.
This invention relates to improvements in the joints for uniting railway-rails, and has for its object to simplify and improve devices of this character and to produce a device which may be cheaply constructed, easily applied, and which will rigidly support the rails and effectually prevent deflection or creeping thereof.
The invention consists in certain novel features of construction, as hereinafter shown and described, and specified in the claims.
In the drawings illustrative of the invention, in which corresponding parts are denoted by like designating characters, Figure 1 is a side elevation. 2 is a transverse section on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of the improved chair detached.
The device may be adapted to any form or size of rail, and consists of a chair with, its lower side extending beneath the abutting ends of the rails 11 12 and with the sides 13 14 extending into engagement with the opposite tie-flanges and vertical webs of the rails, as shown, the side 14, which engages the outer sides of the rails, being extended to a point relatively near the upper faces of the treads or heads of the rails, with the ends thereof inclined downward to guide the rails thereinto in their passage thereover, while the other side will be sufficiently low to prevent interference with the flanges of the passing wheels. The sides 13 14 will be provided with transverse apertures spaced apart and registering with corresponding apertures in the vertical webs of the rails to receive the transverse clamp-bolts 15, as shown. The apertures in the side 14 are preferably square, and the bolts 15 at their head ends will be correspondingly square, as indicated in Fig. 2, so that the nuts (represented at 16) will not be liable to work loose.
The ends of thcchair extend over the adjacent ties 17 18, and between the ties the chair is reinforced by increasing the thickness of the ties and prevent vertical and lateral dis placement, While the depending portion 19, together with its shoulders 20 21, coacting with the spikes, effectually prevent longitudinal movement or the creeping movement of the rails. By this simple means a very rigid solid support is produced which will firmly support the rail ends and effectually prevent movement in any direction.
The chair willpreferably be of cast-steel and may be of any size and adapted to any size or form of rail.
The apertures for the bolts 15 through the vertical webs of the rails will be elongated in the usual manner to provide for the contraction and expansion.
Having thus described the invention, what we claim is- 1. A railway-rail joint comprising a chair adapted to support the abutting rail ends and with extended sides for engagement with the opposite base-flanges of the rails and having transverse spaced apertures, the apertures of one side being angular the chair having central reinforcing portions provided with shoulders for engagement with the adjacent faces of the ties, and clamp-bolts engaging said transverse apertures, and having one end thereof made angular to fit said angular apertures.
2. A railway-rail joint comprising a chair adapted to support the abutting rail ends and with extended sides for engagement with the opposite base-flanges of therails and having transverse spaced apertures, the chair having central reinforcing portions provided with shoulders for engagement with the adjacent faces of the ties, the outer faces of said sides being flush with the lower edges of the chair, and with the ends of said extended sides curving inwardly to provide flanges to receive fastening-spikes.
3. A railway-rail joint comprising a chair In testimony that we claim the foregoing as 1 adapted to support the abutting rail ends and our own we have hereto afiixed our signatures with extended sides for engagement with the in the presence of two witnesses. v
opposite base-flanges of the rails, one of said WILLIAM N HOOPER 5 sides extending to a point relatively near the upper face of the tread of the rail, and having THOMAS SUNDAY the tread thereof curved downwardly at its Witnesses: opposite ends to guide the wheels thereonto W. H. CLARKE, in their passage thereover. JOHN WAHRENBERGER.
