Nrrein SrnfrnsN PATENT CHARLES S. VESTBROOK, OF SPRAGUEVILLE, NEWT YORK. l

RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 302,967, dated August 5, 1884.

Application tiled December l0, 1883. (No modelli To alt whom, t mayconcerft:

Be it` known that I, CHARLES S. XVEST- Bacon, a citizen of the United States, and resident of Spragueville, in the county ot' St. Lawrence and State oi' New York, have invented certain new and useful Improvements in Railroad-Ties, and I do hereby declarethat the following is a full, clear, and exact description of the invention, which will enable oth.- ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is ai perspective view of my iinproved railroad-tie and a portion of the track.

Fig. 2 is a longitudinal vertical section of the same. Eig. 3 is a cross-section with the rail removed, and Figs. fl, 5, and (i-are detail views of the parts of the chair.

Similar letters of reference indicate correspending parts in all the iigures.

wardly-bent flanges, B, at its sides, which iianges are cut out attheir central portion for the largest part of their width, as shown at C, reducing their weight without reducing their strength, and the central portion of the top or upper side oi the tie is cut out to form two, or more or less, apertures, D, through which the ballast may be tamped under the tie. Near the ends ofthe tie it is provided with two pairs of transverse slots, Evand F, through which slots the ends of the chairs G project, by which the rails arev held fast, and the said chairs consist of acentral straight portion,H, extending from one slot to the other upon the Vunder side of the tie,an upwardly and in-.

wardly bent lip, I, at the inner end, and an inwardly-inclined lip, J, at the outer end. A brace-strip, K, of sheet' metal, having its central portion reduced or narrowed, and having its ends L bent upward, is passed with its re- 5o duced central portion between the central portion of the chair and the under side of the tie,

N, having a female threaded perforation, O,

fits, and 'a set-screw, I), having a. locking-nut, Q., turns in this perforation.

It is the rail, which is placed upon the top of the tie, .with the upwardly and inwardly bent lip clamping the inner flange of its foot, and a key, S, having its inner face, T, corresponding in shape to the rshape of the 'outer side of the rail, and having its cuter side, U, of an incline corresponding to the incline of the inclined lip, fits between the outer side of the rail and the inner side of the inclinedlip, and is secured by the screw passing through the block and bearing against its outer side, the said key holding the rail irmly in place. It will be seen that the rail may thus be firmly clamped upon the tie, and that if by accident the fastening-screw should be broken the pyramidal block may be removed from the perforation in the chair and another put in its place with a new screw, obviating the necessity of drilling the broken screw out and making new threads in the perforation and of providing a larger screw. It will also be seen that the tie is less weakened by the transverse slots, through which the lips of the chair pass,than by securing the chair upon the tie, or by securing clamping-lips upon the tie, which are liable to be torn ofi, and thus damage the tie, so as to make it useless.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. rlhe combination of a metallic railroadtie having downwardly-bent flanges upon its sides, and having slots at its ends, a chair having Aits rail-clamping ends projecting through the said slots, and having its central portion bearing against its under side, and a bracingstrip passing between the under side of the tie and the central portion of the chair, and having its ends bent upward, clamping the edges of the downwardly-bent iianges of the tie, as and for the purpose shownand set forth.

2. The combination of a chair having an upwardly and inwardly bent clamping-lip at one edge, and anA inwardly-inclined lip at the other end, provided with a truncated pyramidal perforation, a truncated pyramidal block having/a female threaded perforation, a set-screw7 a rail clamped at one flange of its foot by the upwardly and inwardly bent clamping-lip, and a key fitting between the side of the rail and the inwardly-inclined lip secured by the set-screw, as and for the purpose shown and set forth.

3. The combination of a metallic railroadtie having downwardly-bentilanges at its sides, the central portion of which flanges is cut out for a portion of their width, and having two transverse slot-s at each end, a chair having an upwardly and inwardly bent clamping-lip at one end, and anv inwardly-inclined lip at its other end,'having a truncated pyramidal perforation, both lips projecting through the slots in the tie, a' truncated pyramidal block having a female threaded perforation, a set-screw having` a locking-nut, -a brace-strip narrowed at its center, and having upwardly-bent clamping ends, a railroad-rail, and a key fitting between the outer side ofthe rail and the inner side of the inclined lip7 all constructed as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed n1y signature in presence of two witnesses.

CHARLES S. VESTBROOK.
