MEANS FOR PREVENTING CREEPING OIF RAILS.

Specification of Letters Patent.

Patented Nov. 27, 1906.

To all whom it may concern:

Be it known that I, CHARLES HAYES CAS- PAR, of Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Means for Preventing Cree ing of Rails; and I do hereby declare the fol owing to be a full, clear, and exact descri tion of the invention, such as will enable ot ers skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide improved simple and hi hl -eficient means for preventin track-ra' s om creeping or spreading. T 's I accomplish by provi ing a base-p ate having openings at opposite v sides of the rail-base, the space between the inner Walls 'of such openings `being less than the width of the rail-base, while the space between the outer walls of the two openings is less than the Width of such base plus the tWo spikes. In consequence the spikes as the are driven homecut intothe edges of the rai base, and so interlock' therewith that the rails are held from creeping as well as from spreading. To insure the cutting of the spikes into the rail-base, I rovide means whereby the base-plate is ad 'tionally braced. Although it is desirable to form the flange-engaging face of each spike with a longitudinal rib, yet this is not essential.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawin s, Figure l is a' plan view of a portion of a rai with the retaining-spikes in section. Fig. 2 is an end view of a rail with the base-plate in section, one spike being shown driven home and the other in position therefor. Fig. 3 is an enlarged fra mentary view with the spike in section. igs. 4 and 5 show slight modifications.

Referring to the drawings, 1 designates a tie or sleeper, 2 a rail, and 3 a base-plate upon which the rail rests. This base-plate is of about the thickness of the rail-base at the edges of the liange's thereof. In it are formed two corresponding o eninvs. The space between the inner wal s of t ese two openings is slightly less that the width of the rail-base, as shown in Fig. 2, and the space between the outer walls of these two openin s is less than the Width of the rail-base plus t e two spikes' 4. The base-plate adjacent to each o the openings is formed with a lip or tongue 5,

which-may be provided in the formation of such openings. These lips or tongues are driven down into the face of the tie and serve in themselves to partly hold the latter in place. Their main office, however, is to afford such additional bearings for the spikes that as the latter are driven home their inner faces lwill cut intoA the edges ofthe railflanges. This is shown in dotted lines to the left of Fig. 1 and also in Fig. 3. The extent to which the spikes 'thus'cut into the rail-base is sufficient to hold the rail as a ainst cree ing in either direction. By orming tliie openings in the manner stated as the spikes are crowded in against the rail-flanges the metal of the outer faces is somewhat cut into by the upper edges of the outer walls of the openings.

Although I have shown the sp Y ikes in Figs. 1 and 2 as havin ribs 6 extending longitudinally of their rai -engaging faces so they will cut openings in the edges of the rail-Hanges of less width than the sfpikes themselves, yet, while this is desirable or many pur o ses, it is not really essential that the spi es be sov formed. In Fig. 4 I have shown the s ikes with the longitudinal ribs omitted., The racing aorded by the base-plate is suiiicient to insure the forcing of the spikes into the edges of the rail-flanges sufficiently to prevent creeping. In Fig. 5 I'have shown the rib 6a as being exteriorly curved or rounded instead of V shape, as in Figs. 1 and 3.

The advantages of my invention will be ap-` parent to those skilled in the art.

I claim as my invention- .Y

1. The combination with a tie or sleeper and a rail thereon, of spikes for securing such rail to the tie, and means for forcing the spikes, as they are driven home, tight against the flanges of the rail to form grooves in the edges of such flanges.

2. The combination with a tie or sleeper and a rail thereon, of spikes for securing such rail to the tie, and means for forcing the spikes, as they are driven home, tight against the flanges of the rail to form grooves in the edges of such flanges, said spikes havin each a rib extending longitudinally of that ace thereof engaging the rail-flange.

3. The combination with a tie or sleeper, and a rail, of a base-plate interposed between such tie and rail 4having openings formed therein, and spikes passed through said openings designed to form grooves 'in the edges of the rail-base as they are driven home, the dis- ICC l tance between the outer walls of the o posite openings being less than the width' of t e railbese plus the spikes. ,Y

4. The combination with a tie or sleeper and a rail thereon, of a base-plate beneath the rail having o enings adjacent to the rail` flanges, and spi res designed Vto be driven through said openngs'the distance between the inner walls of said o enings being less than the width of the reiki? tenee between the outer walls of the two openings is less than said width of the rail-base plus the spikes. l .Y v.

The combination with the tie and the rail, of the plate having openings therein on oposite sides of the rail, and spikesdesigned to e driven through seid o enings, the distence between the outer we ls of such o enings being less than the Width of the reilase plus the spikes, and tongues depending :from

said base-plate and designed to enter the tie.
