UNITED STATES PATENT OFFICE.
WILLIAM MILTONl BROVN, OF JOIINSTOIVN, PENNSYLVANIA, ASSIGNOR TO THE JOHNSON STEEL STREET RAIL COMPANY, OF KENTUCKY.
CAST-IVI ETAL BRAC E-CHAI R FO R G RDER- RAI LS.
SPECIFICATION forming part of Letters Patent No. 401,538, dated April 16, 1889.
Application iiled February l5, 1888. Serial No. 264,124. (No model.)
To all whom it may concern/.-
Be it known that I, WILLIAM MILTON BROWN, of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Improvement in Cast-Metal Brace- Chairs for Girder -Rails,
which improvement is fully set forth and illustrated in the following specification and accompanying drawings.
The object of this invention is to provide a rail-chair which shall be secured to the rails by a filler and key without bolts or similar fastenings.
The invention will first be described in detail, and then particularly set forth in the claim.
In the accompanying drawings, Figure 1 shows the chair in end elevation, having the rail shown in cross-section mounted thereon. Fig. 2 is a side elevation of the chair shown in the preceding figure, looking from the right, rail omitted. Fig. 3 shows in perspective the chair illustrated in Figs. l and 2 with rail omit-ted. Fig. 4 shows in perspective the iiller adapted to fit into the chair shown in the preceding iigure.
In said figures the several parts are indicated by letters of reference, as follows:
The letter A indicates the chair; B, the rail; F', Ithe filler; S, the seat for its feather f; K', the key, and S' the key-seat. v
The chair is secured to the rails by setting it up under the headrof the rail and then inserting the filler, as seen in Fig. l. Said ller has a splice-bar fitted upon the web of the rail, and is provided with a feather, f, which fits into its seat S in the chair A. When so fitted, it is confined therein by the key K', driven down vertically in iis seat S', said key passing through the slot .fr in the filler F", thus not only forcing said iiller tight against the web of the rail, but also into firm pressure vertically upward and downward under the head and upon the foot of the rail. The key K' is given suitable taper for the amount of draft desired.
The chairs are suitably braced by braces fw, as commonly practiced, and through the holes H iii the flanges G the chairs are spiked to the cross-ties of lthe track.
Having thus fully described my said i1nprovement, as of my invention I claim- A rail-chair for girder-rails, provided with a filler making a splice-bar iit with the railand formed with a feather, as f, in combination with avertical key, as K', whereby the chair is adapted to be secured to the rail without bolts or other similar fastenings, substantially as and for the purposes set forth.
W. MILT. BROFVN.
