Application filed September 13, 1917. Serial No. 191,321.

To all whom it may concern:

Be it known that I, Hunnnr E. Harms, a citizen .of theUnited States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Means for Fastening Railway-Rails to Ties; and hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enable ct ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

the spike and permitting the wearin away of the contact surfaces intermediate t e bottom of the rail and the plate upon which it rests, thus appreciably lessening the life of both the rail and plate. It is the special object of the present invention to obviate this difiiculty by the employment of a novel form of fastening means locked by spikes,

I so that only a slight space will be permitted at any time between the bottom of the rail and the plate, thereby reducing the wear between the parts to a minimum and greatly lessening the noise, incident to the usual pounding ofiathe rail against the plate.

My invention comprises various details of constructioh combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accome panying drawings which, with the letters of reference marked thereon form a part of this specification and in which:-

Figure 1 is a central sectional View show- This invention relates to new and useful.v

ing, the application of the spikes to the rail.

and tie plate before the spikes are set by the pressure of a train passing over the rail.

Fig. 2 is a top plan view of the tie plate, Reference now being had to the details of r the drawings by letter:

.of which is provided with a head H slightly concaved, as at J, upon its under edge, the forward portion of whichhead is adapted to engage the inclined surface of the flange B of a rail over which it projects, as shown clearly in Fig. 1 of the drawings. The inner edge ofthe spike-H is recessed, as at 0, said recess terminating in a shoulder O. The spike K has a recess. F in its inner edge but differs from the spike H in that the recess-F has an inclined end F. The inner edge of the shank portion of each spike is convexed, as at T, the shank portions of the two spikes being similar intermediate the recemes and their ends, the outer portion of each spike being formed on the line of a compound curve, so that when the spikes are driven into thetie, they will have a wedging action toward the flanges of a railway rail.

Space locking spikes 'S have curved portions and are driven into the tie through the holes through which the spikes H and K pass and serve as additional means for securely holding the spikes in place, especially when used upon curves upon railways where the strain is the heaviest upon the spikes incident to vibration of the rail.

In applying the spikes, the plate C is placed upon the tie, being supported by the spurs D, after which the spikes are driven through spike holes upon one edge or the other of the rail, the spike when first started in the tie being disposed preferably at a slight inclination, with the straight edge of the spike against the edge of the spike aperture and when the spikelis driven down into the tie and the curved portion on the rear edge of the spike begins to have a wedging action against the fiber of the tie, which is compacted as the spike is driven home, the rail will he caused to spring laterally a slight distance carrying with it the plate.

When therecess in the edge of the spike comes opposite the the ii and the plate, the spike will be ii position and the railand plate into the recess, as shown in Fig. l of The spikes upon the opp t ide of the rail are driven into the tie in the manner as bef described, the spike first being started at an inclination and when the outer cain shaped portion or the spike begins to compact the flher oi: the tie, the spike will assume a vertical position and force the plate and rail mounted thereon laterally a slight distance, causing the spikes upon the opposite side to yield slightly until the adjacent edge of the flange of the rail and the spur in the plate come opposite the recess, and the rail and plate will spring back into said recess. After the recessed spikes have been driven into the tie in the manner de scribed, the space locking spikes S are passed through the spike aperturesbetween the recessed spikes and the outer marginal edges of the spike apertures and into the tie, which will securely lock the recessed spike in engagement with the flanges oi the rails and the tie plates.

The spikes being driven in in the positions shown in the drawings, the plate still positioned a slight distance above the tie is forced down on to the surface of the tie by the weight or" a train passing over the rail, and which downward movement of the plate will force the recessed s "ikes down with the plate. As the recessed spikes are further driven down by a train passing over the raid, the fiber of the tie will be further compacted by the cam action:v of the outer edges of the spikes with the tie and cause the spikes to further bind against the edges oi? the flanges of the rail. When the plate is down against the upper surface of the tie there will be a slight space between-the flanges of the rails and the inwardly projecting portions of the heads of the spikes, suficient to compensate -for the vibratory movement incident to trains passing over the track and expansion and contraction. due to variations of temperature.

at I claim to be new is :e-

1. A means for fastening railway rails to ties, comprising, in combination with a tie, a tie plate having spike apertures the ein, spikes adapted to be passed through said apertures and each provided with a recess adapted to receive the flange-0f a rail and the marginal wall of the aperture in the plate, and a locking space spike driven into the tie and positioned intermediate the recessed spike and the wall of the aperture through which the spike passes.

2. A means for fastening railway rails to ties, comprising, in combination with a tie, .a tie plate l'iaving spike apertures therein,

with spurs upon the under surface thereof, spikes adapted to be passed through the apertures, and each provided with a recess adapted to receive the flange of a rail and a spur upon the under surface of the plate, and a locking spike passed through said aperture intermediate the outer wall of the latter and the recessed spike.

A means for fastening railway rails to ties, comprising, in combination with a tie, a tie plate having spike apertures therein, with spurs upon the under surface of the plate, spikes, each with a recess upon its inner edge for the reception of the flange of the rail and spurs, said spike being so formed as tocompact the fiber of the tie as the spike is driven into the latter and causing the spike to bind against the flange of theraii and wall of the aperture in the plate, and a looking spike passed through the spike aperture into the tie and intermediate the outer edge of the recessed spike and the outer wall of the spike aperture.

l. Means for fastening railway rails to ties, comprising in combination with a tie, a

tie plate having spurs upon its under edge and flanges upon its upper surface, said plate having spike apertures the inner ends of which are flush with the edges of said flanges and spurs, spikes having recesses uponQheir inner edges, each recess adapted to receive the edge of the rail flange and the spur a slight space'intervening betweenthe end of the spur and the lowerend of the recess, each spike having a head designed to extend over the flange of the rail and. the inner edge of the spike being convened near its lower end and its outer edge being on the line of a compound curve and terminating in a straight portion near its lower end, a locking spike passing through the spike aperture of: said plate and adapted to bear intermediate. the outer edge of the recessed spike and the end of the aperture.

in testimony whereof I hereunto aihx my signature in presence of two witnesses.
