UNITE STATES PATENT OFFICE GEORGE H. SELLERS, OF RIDLEY PARK, PENNSYLVANIA.

RAIL-CHAIR.

SPECIFICATION forming part of Letters Patent No. 514,243,0'lated February 6, 1894. Application filed February 24. 1891. Serial No. 382.580. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE H. SELLERS, of Ridley Park, county of Delaware, State of Pennsylvania, have invented a certain new and useful Improved Rail-Chair, of which the following is a true and exact description,reference being had to the accompanying drawlngs, which form a part of this specification.

, My 1nvention relates to chairs or supports for ra1lsparticularly to chairs forming a part of metallic railway ties; and it has for its object to provide an efficient and economical device of this kind. d

. The nature of the invention will be best understood as described in connection with the drawings in which it is illustrated and in which- Figure 1 is a plan View intended to illustrate the way in which two of my chairs are secured together to form a tie. Fig. 2 is a plan view of the improved chair or support; Flg. 3 a cross-sectional View taken on the line 12 of Fig. 2; Fig. 4 a cross-sectional view taken on the line 34 of Fig. 2; Fig. 5 a plan view showing a modified form of my chair or rail-support; and Fig. 6 an elevation of the hook-bolt which forms an important feature of my device.

- A A in the drawings indicate the rails; B B, &c., the chairs; these chairs, as preferably constructed, are of rectangular or substantially square form having a downwardly-extending corrugated rim as indicated at O O, &c.; from the upper surface of the chair a platform D, of a breadth preferably considerably 1n excess of the breadth of the rail-base with which it is to be associated,is struck up. Upon the upper portion of which platform the rail is placed in such wise that the rail shall be normally central thereon and the side of the platform substantially parallel to the line of the rail; to this platform and up each side of the rail-base I secure laterally-adj ustable clips G as by inserting them through perforations I I, which, passing through the top of the platform, are sufficiently elongated in a direction transverse to the aforesaid line of the rail to permit of such lateral adjustments of the clips in relation to the said platforms normal rail-bearing area as will be made clear in the later portions of this specification. In order to adjustably secure the preferred form of said clips G, other perforations or holes H H, &c., are formed in the sides of the raised platform opposite to each perforation I; and on the other side of the rail-base on the top of the platform D one or more cavities, as indicated at F, are preferably formed-their function being to contain a block or blocks of vulcanite, hard wood, or other suitable elastic material upon which the rail shall directly rest, it being desirable that the rail should not rest directly upon the metal surface of the platform.

The chair as above described having been placed and secured in proper position, the rail is placed upon it and then the clips, preferably in the form of hook-bolts, such as are indicated at G, the heads G of which extend up through the openings I, and the shanks G of which extend out through the corresponding openings H, are drawn up so as to extend over and clamp the flanges of the railbase down upon the platform D or upon the blocks of vulcanite or similar material indicated at F; the shanks of the hook-bolts G extend beneath the table or rail-supporting part of the chair in opposite directions (see Figs. 2, 3, 4 and 5) and are thus given a bearing against the lower surface of that table which is substantially opposite to the bearing of their jaw faces 9 (see Fig. 6) on the flanges of the rail-base. Thus placed, these bolts are, as further shown in Figs. 2, 3 and 5, firmly forced to place on the flanges of said rail-base by screw-shanks G and aunt or nuts G It will be seen that by the above described arrangement the rail is not only tightly clamped and firmly held upon the platform D, but

that it can be nicely adjusted by lengthening the bolts on one side and shortening those upon the other-this manipulation being accomplished simply by an adjustment of the nuts.

I 'do not in this application wish to be understood as limiting myself to any specific plan of securing chairs in position or together. I have shown in the drawings angle-bars J having their downwardly-extending members fluted or corrugated and which are bolted or riveted to the chairs as shown in Fig. l. The chairs and angle-irons thus combined make a simple and efficient cross-tie upon which a third chair (such as is indicated in Fig. 5) can be secured at any desired position; this chair illustrated in Fig. 5 is especially intended to support a switch rail running between the two main rails of the track and indicated in the drawings by the letter A; and it will be noticed that the platform D in this chair is arranged in an oblique position so that its sides will come parallel with the rail-this arrangement being desirable to aflford better holding surfaces for the nuts G as well as to insure that the rails shall at least initially pass over the center of the platform D.

In order to carry the bearing surfaces of the bolt-shanks G as close as possible to the region of their said hooked clip-heads G, I, as shown in Figs. 4 and 6, preferably fashion the bolt shanks with longitudinal ribs g g which are adapted to bear against the under surface of the table D adjoining the bolthead aperture I, which apertures are in width adapted to accommodate the hooked part G of said bolts only. Also, in order to permit lateral adjustments of the rail when so equipped by means of longitudinal adjustments of said bolts, I further, as shown in Figs. 4 and 5, fashion the bolt-head apertures I with sufficient end clearance, and the bolt shanks threaded parts G2 of suflicient length to afford all ordinary range of adj ustment that may be practical without actual shiftof the chairs upon the cross-tie or sleeper proper.

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

1. A metallic rail-chair having a raised platform in combination with laterally-adj ustable clips arranged to grasp a rail-base on each side and hold it on said platform and means for securing said adjustable clips to the chair and adjusting them laterally all substantially as specified and so that the rail can be adjusted to gage without moving the platform or chair.

2. A metallic rail-chair having a raised platform to support the rail, slotted openings I I, &c., the top of said platform arranged to come on each side of the rail base and corresponding openings H in the vertical sides of the platform in combination with hook bolts G having heads G adapted to pass through openings I and clamp the rail to the platform, and shanks G adapted to pass through the openings II in the side of the platform said bolts being arranged on opposite sides of the rail base, substantially as and for the pur pose specified.

3. A metallic rail-chair having a raised platform to support the rail, recesses E formed in the platform to hold an elastic block or blocks, slotted openings I I, &c., on the top of the platform arranged on each side of the rail base, and corresponding openings H in the vertical sides of the platform in combination with hook-bolts G having heads G adapted to pass through openings I and clamp the rail to the platform, and shanks G2 adapted to pass through openings H in the sides of the platform, said bolts being arranged on opposite sides of the rail-base, gubstantially as and for the purpose specified.

4. The combination with a metallic railchair having a raised platform to support the rail and elongated openings I of transversely adjustable hook-bolts having heads G adapted to pass through elongated openings I; and extended screw-threaded shanks G adapted to pass through openings II in the vertical sides of said chair, said bolts being arranged 011 opposite sides of the rail-base and operative not only to force said bolts hooked heads into appropriate gripping contact with the rail-base but also by mutual adjustments to effect lateral adjustments of the rails which they thus hold, substantially as and for the purpose hereinbefore described.
