RAILWAY-TIE AND RAIL-FASTENING.

:SPECIFICATION forming part of Letters lPatent No. 739,217, dated S p er 15, 1903.

Application filed March I6, 1903- To all whom it may concern:

Be it known that I, PATRICK HENRY QUINN, a citizen of the United States, and aresident, of Corydon, in the county of Warren and State of Pennsylvania, have made certain new and useful Improvements in Railway-Ties and Rail-Fastenings, of which the following is a specification. 3

The object of my invention is to provide an improvement in metallic railway ties and means for securing rails thereto or to other preferred forms of base-support.

The details of construction, arrangement, and combination of parts are as hereinafter described, reference being had to accompanying drawings, in which- Figure 1 is a perspective view illustrating my invention. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. Fig. 3 is avertical section on the line 3 3 of Fig. 1. Fig. 4 is a detail viewillustrating the open slot or notch in the tie. Fig. 5 is a perspective view of the Fig. 6 is a section on the line 6 6 of Fig. 3.

The rail A is constructed in the usual form. The tie B is constructed of metal, preferably rolled steel, and it is made trough-like with two parallel vertical side flanges 19. The latter are provided with notches or open slots b, (see Fig. 4,) which are undercut on the outer side to adapt them to receive the flanged wedge-keys O. Thelatter clamp and secure the rail A to the tie B and upon the wooden base-block D. They are metal bars (see Fig. 5) having the inwardly-bent flange or lip 0, Figs. 1 and 3, which overlaps a base-flange a of the rail A, and on the outer side they are provided with two sets of cams or inclined project-ions c and 0 Thus the key 0 is constructed 011 the outer side of each end portion with a vertical part c, which is inclined inward from one end to the other, and at the lower edge of such incline or cam c is formed anarrow rib or projection 0 whose upper side is inclined from one end to the other.

The flanges b of the tie B are cut away to receive the base of rail A, and; the block'D. supports the latter so that it does not rest upon the flanges. (See Fig. 1.)

In laying the track the ties B are fixed in position with the flanges b upward, andt'he latter may be flush with the road-bedor not,

as preferred. Then the rails A are laid on the'blocks D and ties B and the keys 0 inserted and driven into placeby a hammer,

sledge, ormaul. It will be seen that in such case the lateral inclines or cams 0 engage the inward projections, Fig. 4, of the slots in the tie B, so that the key 0 is forced against the edge of the rail-base a .while the inclines or cams c engage the under side of such projections and draw the keys 0 downward upon the rail-base a. In brief, the effect is to clamp the rail A very firmly to the ties both.

of the block D has a transverse groove which receives a metal fastening E, Figs. 2 and 3, the same lying flush in said groove and havlng upturned ends that engage notches in railbase Ct. By this means crawling or creep-v ing of the rails A is mainly prevented.

It is apparent my improved key or wedge fastening may be applied or used with other forms of base-support than the metal ties described-for example, with wooden ties having the usual form of flanged-head spikes.

By the above-described construction and combination of parts I provide an improvement in ties and rail-fastenings which is distinguished. by simplicity, strength, security, durability, and cheapness. The tie has also a certain degree of elasticity, whereby an advantage is attained in wear and easy running of rolling-stock. The bottom of the tie is pro-- vided with holes to permit escape of water.

The holes enable the tie to take a firmer holdon'the earth, which aids in preventingislipping of the tie endwise. The bur or rough edge formed in punching the holes is a fur ther aid to this result.

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

1. The combination,with a flanged metallic vided with undercut, open slots, of a fasten- ICO rail, and a tie having vertical flanges proing consisting of a flanged bar having a lateral incline and a horizontal incline, which, when the bar is forced into place, act as cams upon the lateral and under sides of said slots, as and for the purpose specified.

2. The combination, with rails and a basesupport therefor having metal parts which project inward and above the body of said support, of the fastening comprising a flanged bar having on its outer side two inclines adapted to apply lateral and downward pressure on the bar, substantially as specified.

3. The combination, with the flanged rail and a tie having undercut, open slots, of the fastening key having a lateral projection whose upper side is inclined downward from the outer to the inner end, as shown and described.

specified.
