Specification of Letters Patent.

Application filed December 28, 1914. Serial No. 879,285.

To all whom it may concern:

Be it known that I, THOMAS D. DALL- MEYER, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Rail-Anchors; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to rail-anchors, or anti-creeping devices for railroad-rails.

The object of my invention is to provide a one-piece,-rself-locking rail-anchor which will grip the rail with great tenacity and prevent the creeping of the same.

-To these ends my invention comprises, generally stated, a rail-anchor formed of a single piece of metal having the proper amount of resiliency, the anchor having inwardly' turned ends engaging opposite flanges of the rail, one of the inwardly ex tendin ends having a notch or recess found therein normally out of line with the flange of;;the rail, when not in gripping engagementtherewith, and adapted to be brought into gripping engagement with the rail flange by forcing the end portion down and springing the end portion against the flange with the flange entering said recess or engaging the shoulder formed by said recess.

In the accompanying drawing, Figure 1 is a cross-section-of a rail showing my improved railanchor applied thereto but not gripping the rail; Fig. 2 is a like view showing it gripping the rail; and Fig. 3 is an endview showing the rail-anchor in engagement with the tie.

In the drawing, the numeral 2 designates a rail of ordinary cross-section with the head 3 and the flanges f. My improved railanchor is made of one piece of metal having the proper amount of spring or resiliency. It consists of the body-portion 5 with the inwardly bent ends 6 and 7 The end-portion 7 projects up above the endportion 6 when the rail-anchor is applied to the rail but before being gripped thereby, and said end-portion 7 has the notch or recess 8 which is above the edge of the flange, said recess forming the shoulder 8 The rail-anchor is formed with the slight bulge 9 and when the anchor is applied to the rail, as indicated 'in Fig. 1, the inwardly extending end 6 fits over the flange of the rail and may be driven into position with the bulge 9 engaging the bottom of the rail, said inwardly extending end and said bulge forming a j aw to grip the flange. In order to force the anchor into gripping position, the inwardly extending portion 7 is forced downwardly by. a sledge or in any other suitable manner, the metal springing outwardly to pass the flange, and when the notch 8 comes in line with the edge of the flange'it springs inwardly and engages the flange as indicated in Fig. 2 by a self-locking engagement. The shoulder 8 engages the lower face of the rail base, holding the anchor in position. When the shoulder has been brought into engagement with the rail base, the bulge 9, merely bears against the lower face of the rail base but without any appreciable pressure-as the springing of the anchor into position by the downward movement of the end portion 7 the anchor is securely clamped in position without the assistance of the bulge 9. In this manner, the device is quickly applied and the gripping action brought into play by the simple blow of a hammer, and when the rail-anchor is once applied to grip the rail, as in Fig. 2, it grips the rail with great tenacity and takes hold securely against movement.

The body-portion 5 of the anchor engages the tie 10, and so prevents the creeping of the rail.

The device being formed of one piece can be readily formed in dies and the cost of manufacture of same is reduced to a minimum. 7

What I claim is:

1. A rail-anchor formed of a single piece of spring-metal having inwardly extending ends, one end fitting over the flange at one .side of the rail, and the opposite end having a notch normally above the flange and adapted to be forced-downwardly to bring said notch into engagement with the flange of the rail.

2. A rail-anchor formed of a single piece of spring-metal having inwardly extending ends, one end fitting over the adjacent flange, the body-portion having a bulge engaging the oottom of the rail adjacent to said end-portion, and the opposite end having 'a notch normally above its adjacent flange and adapted to be forced downwardly Patented Feb. 1L3, 19W.

to bring said notch into engagement with bring said shoulder into engagement with the flange of the rail on that side. the lower face of the rail flange. 10

3. A rail anchor formed of a single piece In testimony whereof, I the said THOMAS of spring metal having inwardly-extending D. DALLMEYER have hereunto set my hand.

5 ends, one end fitting over the flange at one THOIVIAS D. DALLMEYER. side of the rail, and the opposite end hav- Vitnesses: ing a shoulder normally above the flange Row. D. T TTEN,
