ANTIGREEPING DEVICE FOR RAILWAY RAILS Filed. Nov. 10, 1928 ATTORNEY Patented Jan. 7, 1930 UNITED STATES EMIL F. HOLINGEB, OF NEW YORK, N. Y.

ANTICREEIING DEVICE FOR RAILWAY RAILS Application filed November 10, 1928.

The invention relates to anticreepers or rail anchors in which the base-flanges of the rail are held between a fixed abutment on the tie-plate and a gripping member movably engaged with the tie-plate opposite such abutment, and the object of the invention is to provide an economically manufactured structure of this character by which the rail is securely held against longitudinal movement relatively to the tie-plate and the gripping member held in reliable engagement with the rail and tie-plate.

The invention consists in certain novel features of construction and arrangement by which the above and other objects are attianed, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show approved forms of the invention.

Figure 1 is a plan view showing a portion of a rail supported upon and engaged with the improved tie-plate and a preferred form of the gripping member.

Figure 2 is a vertical section taken transversely of the rail, on the line 2-2 in Figure 1, and partly in elevation.

Figure 3 is a vertical section through a portion of the tie-plate and gripping member, on a greatly exaggerated scale.

Figures 4 and 5 are plan views showing modified forms of the gripping member, on a scale larger than that in Figures 1 and 2.

Similar reference numerals indicate the same parts in all the figures.

The rail may be of anly approved type having the head 6, vertical web 7, and inside and outside base fingers marked respectively 8 and 9, supported on a tie-plate 10 of peculiar construction and held in place thereon and to the tie, not shown, by spikes 11 or other means.

On the upper face of the tie-plate, near one end, is a transverse abutment 12 extending parallel with the outer base-flange 9 serving to hold the latter against outward lateral movement relatively to the tie-plate.

A curved slot 13 having parallel sides and semicircular ends is punched in the tie-plate preferably on the centre line thereof and ad- Serial No. 318,361.

jacentthe inner base-flange 8, extending longitudinally of such flange on a curve struck from a centre beneath the rail.

The gripping member comprises a stud or pin 15 having a head or disk 14 adapted to lie upon the plane upper face of the tie-plate adjacent the inner base-flange 8. The stud 15 is circular in cross-section and preferably slightly tapered upwardly from its base 16 to its junction with the head at 17 as clearly shown in Figure 3, and the head is serrated vertically on a portion of its periphery as at 18 next to the base-flange 8 when in position.

The diameter of the base 16 of the stud is the same as the width of the slot 13 so that this the slot 13 and forcing the head 14 into close contact With the plane upper face of the tie-plate. This same forcing movement causes the teeth 18 to bite slightly into the edge of the base flange 8 and, when thus engaged, the longitudinal movement of the rail causes .the head 14 to rotate partially'and due to the eccentricity of the stud 15 to bite more strongly into the base flange and force the rail against the abutment 12, while at; the same time the stud 15 rolls slightly in the slot 13 in the direction to increase the grip on the rail.

It will be noted that the strain of the engagement is resisted by the stud and wall of the slot 13 and by mounting the stud in this manner a new surface of the slot-wall and also of the stud is presented at each advance of the gripping member and by curving the slot as above described the gripping action is increased by such advance.

Any tendency of the head to rise in consequence of the lifting movement of the rail is resisted by the cramping action of the stud in the slot 13. The effect of such movement tends to lift the toothed portion 18 of the head and depress the opposite portion; this canting tendency is effectually resisted by the contact of the stud with the wall of the slot and further to increase such resistance the stud is tapered as above described so that its lower edge at 16 tends to' jam into the adjacent wall of the slot and hold the stud against the upward movement.

. The shape of the head may be varied. Figure 4 shows a head 19 of elliptical form with its stud centrally mounted and Figure 5 shows a head 20 of general circular form with portions of the circle omitted. Other forms may be adopted as found desirable, the action being the same in all cases.
