Application filed January 8, 190.81 Serial No. 409,872.

To all whom it may concern:

Be it known that I, Gnonons LAKHovsKY, resident of 5 Avenue du Bois de Boulogne, in the city of Paris, Republic of France, have invented Improvements in or Connected with Means for Fastening in Position Railway-Spikes or the Like, of which the following is a full, clear, and exact description.

The present invention relates to a metallic fitting constituting a kind of divided nut adapted to fix itself in railway sleepers to receive the ordinary spikes employed either for retention of broad footed rails or for fixin in position the chairs which receive doub e headed rails.

This fitting can be applied either to new i or to old sleepers; in the former case it permits soft wood to be utilized as sleepers for railways by lining the walls of the spike holes with metal; 11'! the latter case the same fitting may be fixed in the spike holes and thus permit old sleepers of hard wood to be utilized without its being necessary to bore new holes the old holes simply being enlarged to the diameter of the fitting. F urthermore, the spike, fixed in the sleepers by the aid of this fitting possesses much more durability and resistance to drawing out than those fixed directly into the wood. The fibers of the wood are compressed and hardened owing to the outline or profile of the fitting at first at the time of putting in place the shells in the sleeper and afterwards when the spike is screwed into the same in such manner that the nut so constituted possesses a large amount of resistance to drawing out.

This fitting, which forms a metallic nut, also allows the spike to be withdrawn when desired without in any way disturbing the solidity of the structure inasmuch as the screwing and unscrewing of the spike cannot injure the thread of the screw or of the nut. Furthermore, the spike can be tightened up many times if in use the arts become loose owing to the play of the s eepers.

In the accompanying drawings: Figure 1 is an elevation of a duplex fitting constructed according to the resent invention. Fig. 2 is a lan thereo Fi 3 is an inside elevation 0 one of the two shells constituting the fitting. Fig. 4 represents the ap lication of this invention to the fixing of a road footed rail upon a sleeper. Fig. 5 shows the application of the invention to the fixing of a chair for a double headed rail. Fig. 6 is an elevation of an instrument for placing the fitting in position.

Referring to the drawings the fitting is formed by two metallic shells a half cylindrical in section and independent of one another. These shells are interiorly formed with a female screw thread inclosing a conical cavity 5 to receive the stem of the ordinary spike 0 employed on railways for the fixing of the rails. Upon their exterior the shells a are formed with a number of steps or teeth d arranged circumferentially and also with longitudinal beads or projections 6 formed preferably along the edges of the shells. The teeth d are adapted to enter and compress the fibers of the wood in such manner as to prevent the pullin or working out of the fitting a while the ribs e prevent the shells a turning in the hole f in the sleepers when the spike is screwed thereinto. After having bored or rebored the holes in the sleeper to a suitable diameter the fitting is placed in position by forcing into the hole the two shells a by means of an appropriate instrument such as that 9 (Fig. 6) which is driven by the aid of a hammer until the upper edge of the fitting has descended slightly beneath the surface of the sleeper. The s ike c is then screwed into the fitting until its head bears upon the foot h of the rail or upon its chair i. During this operation, the spike c, which is entering the fittin a, owing to the conical screw thread Z) thereo causes the spreading apart of the two shells which has the effect of compressing the fibers of the wood and causing the steps or teeth 05 to enter the wood thus securely fixing the parts in position.

The operation of screwing up the spike can be performed without fear of turning the shells a which form the nut owing to the said longitudinal ribs or beads e.

In the fitting adapted to broad footed rails as shown in Fig. 4, one of the shells is formed shorter than the other so as to avoid the foot of the rail coming into contact with said shell when screwing or tightening up the spike.

The fitting adapted to rail chairs 2' is, as shown in Fig. 5, preferably provided with a washer of hard wood 7' interposed between the underside of the chair and the upper edge of the fitting.

The washer g has for its object to fill in the gap left in the spike hole in the sleeper to permit the subsequent ti htening of the chair by screwing u the spi e 0.

- The forms, detai s, accessories, materials and dimensions of this fitting may be varied without departing from the principle of the invention.

Claims:

1. A socket having an interiorly screw threaded conical cavity, said socket being divided longitudinally into sections.

2. A socket having an interiorly screw threaded conical cavity, said socket being divided longitudinally into sections, the edges of the sections being provided with laterally projecting ribs for the purpose set forth.

3. A socket having an interiorly screw threaded conical cavit said socket being divided longitudinally into sections, the outer face of the socket being provided with u Wardly facing teeth for the purpose set fortii.

4. A. socket havin an interiorly screw threaded conical cavity, said socket being divided longitudinally into sections, and a washer arranged between the sections and the rail chair for the purpose set forth.

The foregoing specification of my improvements in or connected with means for fastening in position railway spikes or the like signed by me this 26th day of December,

GEORGES LAKHOVSKY. Witnesses:
