ANTIGREEPER FDR, RAILS.

Specification of Letters Patent.

Application filed November 1, 1915. Serial No. 59,069.

'0 all whom it may concern: I

Be it known that I, HORATIO G. GIILMOR, a citizen of the United States, residing at IVashington, in the District of Columbia, have invented a new and useful Anticreeper for Rails, of which the following is a speci fication.

This invention relates to devices known .as anticreepers, rail anchors or rail stays and one of its object-s is to provide a simple device to prevent the creeping of the rails of railways. I

Other objects are to provide a device, which shall be effective to prevent longitudinal or creeping movement in either di rection, which may therefore be applied to either side of the rail, which may when desired be used in conjunction with a tie plate and which will, when so used, leave the rail free to slight vertical movements in rela tion to the tie plate.

In the accompanying drawings, in which one embodiment of the invention is illustrated,

Figure 1 is a side elevation showing the device in operative position on the rail.

Fig. 2 is a sectional view at the plane indicated by the line X X in Fig. 1.

Fig. 3 is a sectional view at the same plane illustrating the mode of applying the device.

Similar letters refer to similar parts throughout the several views.

In the form of the invention illustrated in the drawings, A represents-the rail resting upon a tie plate B, which in turn rests upon the ties or sleepers, a portion of one of which is shown at C and is fastened there to by spikes or screws D and 1),. The tie plate may be provided with a portion engaging one edge of the rail base flange, as at E In Figs. 2 and 3, or the spikes D may serve a like purpose. At the other side of the base flange of the rail, the tie plate B is provided with an aperture F, the sides G and H of which may be slightly inclined as may also be the sides I and K, shown dotted in Fig. 1, so that the aperture F may be slightly larger at the upper face of the plate B than it is at the lower face. L is a bar, arranged with a portion M projecting into the aperture F of the plate B, a portion N, the surface 0 of which is adapted, when the bar is in operative position, to engage with the upper surface of the base flange of the rail and a portion P, the surface Q of which, in the operative position, engages with the under surface R of the head of the rail. The relation of the portions M and N to the remainder of the bar L is such that, when the portion M of the bar L is inserted in the aperture F of the plate B, the surface 0 of the portion N of the bar L will engage the upper edgeor corner of the rail base flange, as at S in Fig. 3, and the portions M be sprung, strained or deflected, under stresses-to be hereafter described, to'bring the surface 0 into engagement with the upper surface T of the base flange of the rail, as shown in Fig. 2.

In applying the anticreeper to the rail the plate 18 is first placed in position and the spikes D and D placed. The bar L is then placed with the portion M inserted in the aperture F of the plate B and the por? tion N engaging and fulcruined upon the rateiitea Mar. a, rare and N of the bar L mustv top or corner of the edge of the rail base flange, as illustrated in Fig. 3. With the parts in this position the surface Q of the portion P will begin to engage the surface It of the under side of the rail head. By driving the upper part of the bar L, preferably by striking the surface U with a hammer or maul. the surface Q will be forced to moveover the surface R and stresses will thereby be transmitted to the portions N and M of the bar L which will strain or deflect these portions. The portion M of the bar L will be forced into close engagement with the side II of the aperture F in the plate B at V and lateral forces causing the spikes or screws D and D, and the surface E of the plate B to be pressed against theopposite edge of the base flange of the rail will be produced and the portion N, bearing at first upon the rail base flange at S, will be forced downward. By driving the bar L to the position shown in Figs. 1 and 2, the surface 0 of the portion N of the bar L will be forced into contact with the upper surface T of the rail base flange and caused to press downwardly upon that surface with pressures, the intensity and distribution of which will depend upon the elastic strength of the material of which the bar L is made. At the same time the surface Q of the bar L will engage and press upwardly upon the surface R of the rail head.

tion of length of the rail. The spikes or screws D and D securely fasten the plate to the tie C so that longitudinal movement of the rail, in either direction, will be effee tually prevented. The engagement of the portion M of the bar L with the aperture F of the plate B and the pressing of the surfaces E of the plate B against the edge of the rail base permit slight vertical movement of the rail in relation to the plate B without ffecting the tightness of the parts upon the rail or their efficacy in preventing longitudinal movement of the rail.

It Willbe obvious that the plate B, instead of being fastened to the ties C might be provided with one or more flanges or abutments arranged to engage the faces of the ties C to hold the plate B and therefore the bar Land the rail against the creeping forces. While I have described my invention in one embodiment it will be understood that modifications might be made as to details of construction without departure from the principles of the invention; therefore. I do not wish to be'understood as" limiting the invention to the devices, construction and arrangement shown and described except so far as such limitations are expressed in-the claims.
