Specification of Letters Patent.

. Patented Oct. 28, 1913.

- Application filed October 24, 1912. .Serial No. 727,535.

The object of this invention is to provide.

a rail-supporting device, or tie-plate, as it is most commonly termed by those skilled in the art, which will serve to support the track rail in such manner as not to interrupt the wave motions thereof causedby passingof trains.

Another object is to provide an economical means of support for a rail which may be easily replaced without the necessity of removing the rail or interfering with its position.

Still another object is to provide a railsupporting means adapted to be carried by the conventional form of any tie now in use, if so desired, in such a manner that the tie is to all intents and purposes preserved from the cutting or crushing effect of the rail, and so that if found desirable the tie proper may be embedded in the road ballast to the greatest possible extent, thereby increasing the stability of the entire tracking system without interfering with the support of the rails, and providing for an easier riding track, as well as minimizing the displacing of the ties and grinding of track when used as art of an electric railway signal system.

ther objects will be made apparent in connection with the accompanying drawings, in which Figure 1 is a side elevation of my improved device showing the rail in cross section. Fig.2 is a plan view of the assembled device. Fig. 3 is a side elevation, looking in a direction at right angles to Fig. 1 and with the fastening means removed. Fig. 4: is a detail cross section taken on the line H of Fig. 2, showing a cut spike in elevation. Fig. 5 is a view similar to Fig. 4 taken along the line 5-5 of Fig. 2,; showing the screw spike in elevation. Fig. 6 is a per spective View of the device proper; and

Fig. 7 is a perspective view of the wood" block.

Like numerals refer to like, elements throughout the drawings, in which- 10 designates a cross tie of the form usually used in track construction, and 16 is a rail, also of conventional construction. This .railis provided with the usual flanged base 17, having lateral edges 17, as shown in Fig. 1 of the drawings.

My invention comprises a block or pad 18, preferably formed of a hard wood, such as beech, etc., which is preferably provided with spiking apertures 18see Fig. 7.

Mounted on this block is a metal frame 19,v

having a pair of downwardly extendin sides 20 adapted to embrace and closely t the sides of the block 18, as shown in igs. 3 and 6. These sides of the frame 19 preferably terminate short of the bottom of the block. Extendingbetween the sides of the frame 19 are the top portions or

cross pieces

21 and 21, the latter being preferably of greater width than the former, for a purpose to .be hereinafter described. These top portions are spaced a art a suitable distance to accommodate t e base of the rail.

It is to be noted that in referring to the width of the

top portions

21 and 21, the distance from the side adjacent the rail base to the opposite parallel side is intended. The inner sides of the cross pieces are preferably so located as to contact with the lateral edges 17 of the flanged base of the rail, as shown in Fig. 1. The portions of-the sides 20 of the metal frame extending between the

cross pieces

21 and 21 are preferably constructed so as to terminate short of the top of the block 18 directly under the rail base, thereby obviating any contact be tween the base of the rail and the sides of the metal frame.

Each of the cross pieces 21 and "31 is preferably provided with a circular spiking aperture 14 and a rectangular cut spike aperture 15, both of said apertures in each to portion being diagonally opposed to the similar aperture in the other cross piece, as shown in Fig. '6. Partially surrounding the circular spi ring aperture 14 is a raised shoulder 22, having a dished-out portion 23 immediately surrounding the aperture. These spiking apertures are so constructed as to partially open into the space between the

cross pieces

21 and 21, the inner periphery of the aperture embracing sufiicient of the screw spike to prevent lateral movement.

layer of felt a is used and placed between the wood block and tie to absorb moisture and minimize danger of same rotting wood plock, as well as to form a good seat there- When the device proper is assembled and set in place, the block 18 is inserted in the frame 19 and both placed in the desired position on the felt layer or the tie, or other supporting means, 10, the apertures 18 of the wood block being located beneath the

respective apertures

14 and 15 in the frame. Cut spikes 30 may then be driven through the

apertures

15 and 18 into the'tie 10, as shown in Fig. 4. The spike 30 is provided with a head 31 and with outwardly extending portions 29 below said head which are fitted into and engaged by the notches 28 to prevent lateral movement of said spike after being driven to position.

The shoulder 27 furnishes a limit for the downward movement of the spike 30, the top of the inclined portions 27 a of said shoulder furnishing a seat or restraining means for the under portion of the head 31 of the spike, thus securing the said parts firmly in position. The notches 28, as already set forth, act to retain and hold the head 31 of the spike slightly out of mediate contact with the base of the rail. The screw spikes 25 may be forced into engaging position through the spiking apertures 14 and corresponding apertures 18 in the block 18. These'screw spikes are provided with heads 26, the under surfaces of which are adapted to fit the dished-out portions 28 of the surrounding shoulder 22, so as to retain and hold the head 26 of the spike25 slightly out of contact with the base of the rail.

By so locating the cut and screw pikes, it minimizes the danger of splitting the wood block, and it will be apparent that the slight wave motions, both vertical and longitudinal, of the rail may be uninterrupted without tending to withdraw the spikes by the rail-base, as is now found to be present in ordinary track constructions. The metal frame serves also to prevent the wood block from splitting, and it will be apparent that any side thrusttransmitted from the flange of the rail-will be distributed by the frame to both sets of spikes. Furthermore, the shoulders located in the back of the cut and screw spikes will serve to prevent backward bending of the spike heads, should the railbase be forced against them.

It will be seen that the wood block furnishes the main contacting as well as the cushioning support for the track rail, and inasmuch as this block may be of any desired length, the friction present between the base of the block and the top of the tie 10 may be increased by increasing the length of said block in the desired direction. Since no downward thrust is imparted to the metal frame, and since this metal frame is entirely out of contact with the tie 10, it will be'apparent that cutting and crushing of the tie itself will be practically obviated. The wearing efiect, etc.,due to the support of the rail-will be sustained by the wood block 18. It is obvious that this block when worn out may be readily replaced or renewed by removing the spikes, without affecting the position of the tie or necessitating tampering with the road ballasting. By diagonally opposing the screw and cut spike holes the position of the metal frame may be reversed, or the position of the wooden block may be reversed with respect to the metal frame, thus utilizing the frame drive spike holes for the screw spikes, and vice versa.

It'is to be noted that I have constructed one top portion 21 of greater width than the top portion 21. This top port on 18 adapted to be located at the outer side of the rail, where the greater thrust naturally occurs, and where the greatest amount of frictional resistance is required.

While I have described and shown my invention with more or less particularity, I do not wish to be unduly restricted to such description and showing beyond the scope of the appended claims.
