FAS-TENING- DEVICE FOR RAILROAD-TRACKS.

Specification of Letters Patent.

Patented J une 23, 1914.

Application inea october 15, 1913. serial No. 795,229.

To all whom t may concern Be it known that I, JOI-IN LUNDiE, a citizen of the United States, residing at New York, borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Fastening Devices for Railroad-Tracks, of which the following is a specification.

rllhe general object of this invention is to provide a back rest for the head or projecting flange of a fastening device of the nature of a spike that secures a rail of a railroad track in position.

A more specific obj ect of the invention is to provide a tie plate with a device fastening it to the tie, which fastening device in turn serves as a back rest for a fastening device securing the rail of a railroad track in position.

A. still more specific object of the invention is to provide a tie plate with a lag screw and a washer for fastening said tie plate to the tie, which washer, in addition to serving as a bearing for the lag screw, serves as a back rest for a screw spike securing the rail of a railroad track in position.

Further objects are to provide practical, eliicient and simple means for securing the rails of railroad tracks in position.

r1`hese being among the objects of the invention, the saine consists of certain features of construction and combinations of parts to be hereinafter described and then claimed with reference to the accompanying drawings illustrating a suitable embodiment of the invention, and in which- Figure 1 shows a cross section of a rail and tie-plate and the improved means for securing the railroad tracks in position; and Fig. 2 is a perspective view of a washer used in the form of the invention shown in Fig. 1.

The usually wooden tie 10, the rail 11 and the tie-plate 12 may be of any suitable con struction and type. The form of tie-plate shown is that which is covered by my United States Letters Patent #1,065,696 dated June 24, 1913. Obviously this is but one of many forms of tie-plate which may be employed.

For the purpose of securing a tie-plate to a tie, preferably a lag screw 13 having a head 14 is passed through a washer 15, and the said lag screw is also passed through a hole 16 in one edge of the tie-plate and screwed home into the tie. The washer 15 may be of any suitable cross-section verti cally, but is here shown as tapering at bottom and top so that it will accommodate itself to the surface of the tie-plate and to the screw spike or the equivalent which is used conjointly with the lag screw and washer or the equivalent. A screw spike 17 is provided having a head 18, and said screw spike is passed through a hole 19 in the tieplate, which hole is located between the seat for the base of the rail 11 and the hole 16 for the lag screw. 1When the screw spike is screwed home into the tie, one side of its head 18 rests or bears upon the contiguous side portion of the washer 15. The height of the said side portion of the washer is such that when the screw spike is screwed ho-me with its head resting on said washer, the opposite side of the head of the screw spike will be located suiiiciently above the rail base to clear it. rlhis clearance is desirable in practice although in a poorer construction the head of the screw spike may rest upon the rail base.

1t will be seen that when the screw spike is screwed home, the arrangement and proportions of the concomitant parts are such that no breaking off of the head of the screw spike can occur if the spike be in good condition. Obviously, and as shown in the drawings, parts-the substantial duplicate of those described,-are employed at both sides of the tie-plate, that is on opposite sides of the rail, sothat the tie-plate is substantially secured to the tie, and the rail is properly held in position. As indicated at 20, each washer may be provided with a depressed seat for seating the head of the screw spike, so that said head and seat act together to prevent the washer from turning.

Gbviously the invention claimed is susceptible of modification as the improved fastening device is not restricted to the construction shown.

What I claim as new is 1. rlhe combination of a tie-plate, a headed fastening, a washer, said fastening passing through said washer and tie plate, and secured to the tie, and a spike passing through said tie plate and secured in the tie, said washer serving as a rest or bearing for one side of the head of said spike, whose other side is over the rail base.

2. The combination of a tie-plate, a lagscrew, a washer, said lag-screw passing through said washer and tie plate, and sethrough said tie plate cured to the tie, and a screw spike passing through said tie plate and secured in the tie, said Washer serving as a rest er bearing for one side of the head of said spike, Whose other side is over the rail base.

3. The combination of a tie-plate, a head- Y ed fastening, a Washer, said fastening passing through said Washer and tie plate and secured to the tie, and a spike passing through said tie-plate and secured in the tie, said Washer being of such thickness to serve as a rest or bearing for one side of the head of said spike, While the other side is over and spaced away from the rail base.

4; The combination of a tie-plate, a headed fastening, a Washer, said fastening passing through said Washer and tie plate, and secured to the tie, and a spike passing and secured in the tie,

said Washer having a depressed seat serving end of said tie plate,

as a restA or bearing for one side of the head of said spike, whereby said washer is secured against turning, the other side of said head being over the rail base.

5. The combination of a tie-plate, a headed fastening, a spike being located at one and both said fastening and spike passing through said tie-plate in juxtaposition and secured in the tie, said fastening and spike being arranged on a line transversely of the rail and abutment means for the contiguous sides of the heads of said fastening and spike, which means is separate from said tie-plate and is located wholly te one side of the rail.
