BRAGE CHAIR FOR GIRDER RAILS.
Patented Dec. 4, 1888.
lms enwv UNITED STATES PATENT OFFICE.
ARTHUR J. )IOXHAU, OF JOHNSTOlVN, PENNSYLVANIA.
BRACE-CHAIR FOR GlRDER-RAILS.
SPECIFICATION forming part of Letters Patent No. 394,078, dated December 4, 1888.
Application filed February 13,1888. Serial No. 263,838. (No model.)
.To aZZ whom it may concern:
Be it known that I, ARTHUR J. M OXHAM, of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Brace-Chai r for Girder-Rails,which invention is fully set forth and illustrated in the following specification and accompanying drawings.
The object of this invention is to provide a ra'ihchai r of the form shown which will hold the rail securely inv its place and firml resist the pressure of any load that may come upon it.
The invention will first be described, and then particularly set forth in the claims.
In the accompanying drawings, Figure 1 shows the chair in end elevation, having a rail shown in cross-section secured thereto. Fig. 2 shows a side elevation of Fig. 1, viewed from the left-hand side of said figure.
In said figures the several parts are indi cated by letters of reference as follows: The chair B may be made of cast-iron, steel, or other suitable metal, and is provided with a groove or slot down through its middle, in which the web of the rail A is inserted. Through the body of said chair a hole or slot is made, in which the hook-head of an anglebolt, Cfis passed. Said head of said bolt at the same time passes through an elongated hole or slot in the web of the rail A, which slot registers with thehole, before mentioned, in the body of the chair. On one side of the chair B is formed the lug E, provided with a slot, through which'the bolt 0 is passed. The nut D, being entered upon the screw-thread of the bolt (1 below the lug E, tightens the bolt C when set up against the lug E, a recess being left in the body of the chair below the lug E to permit of the turning of said nut.
The chair B is provided with webs F F for necessary strength and stiffness, if required,
and affords ample support to the head of the rail A by coming up under the same, as shown at the point f, at which point the thrust of the cars running upon said rail, or due to passing vehicles of any kind, is the greatest. The bolt 0 has formed at its outer end a shoulder, c, which prevents the bolt from bein drawn back when tightened up. The holes in the chair B and the web of the rail A are so arranged or located with reference each to the other that the tightening of the bolt C by setting up its nut I) will draw the rail firmly down to its bearing in the chair 13. The base of the chair B is provided with holes e, for securing the chair to a wooden cross-tie or other base-piece by spikes or other fastenings. The holes in the web of the railv A for the bolts 0, being elongated, or, more properly, slots, as shown in dotted lines (I, Fig. 2, amply provide for longitudinal expansion and contraction of the rail.
Although a side-bearing rail is shown in the drawings, this chair may be readily adapted to conform to any girdei rail having a plain vertical web.
l'l'aving thus fully described my said bracechair and its purposes and objects, as of my invention I claim 1. A rail-chair slotted verticall to receive the web of a girder-rail and horizontally to receive a bolt, and provided with a slotted horizontal lug, as E, substantially as and for the. purposes set forth.
The combination, with a rail-chair slotted to seat the web of a girder-rail and provided with a horizontal perforated lug, as E, of a hook-headed bolt, as C, provided with an offset in its head to nip the web of the seated rail, substantially as and for thepurposes set forth.
