RAIL-ANCHOR.

Specification of Letters Patent.

Patented Aug. L5, 1916.

Application filed November 5, 1913. Serial No. 799,343.

To all whom it may concern:

Be it known that I, JOHN citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

My invention relates to devices for preventing the longitudinal creep of railroad M. Soorr, a

rails produced by the passage of trains over. the road, such devices being commonly called rail anchors, rail stays or anticreepers.

The principal object of the invention is to provide a device of this character whlch will be very simple in its construction, light in weight, inexpensive to manufacture, and easily applied to the rail; and which, moreover, will take a very firm and reliable grip on the rail and will be extremely strong and rugged in its construction so as to resist the great stresses to which devices of this sort are subjected.

The invention consists of the several devices, constructions and arrangements in rail anchors, which will be hereinafter more particularly described and claimed, for carrying out'the object above stated.

The invention is illustrated, in a preferred embodiment, in the accompanying drawings wherein Figure 1 is a plan view of the device shown as applied to a railroad rail; Fig. 2, a sectional elevation taken on line 2-2 of Fig. 1; Fig. 3, a fragmentary sectional view on line 3-3 of Fig. 2; Fig. 4, a plan view of one of the two co-engaging elements of which the device is composed, and Fig. 5, a side View of the other of said elements.

Like characters of reference designate like parts in the several figures of the drawings.

Referring to the drawings, A designates a railroad rail and Bone of the ties supporting the same.

The device of my invention preferably consists of two elements C and D, shown separately in Figs. 4 and 5 respectively. Both may be and preferably are malleable iron castings, although other metal might be employed.

The element C consists of a bar formed at one end with a jaw E adapted to engage one edge of the base flange F of the rail A and at the other end with a slot or opening G having a circular enlargement H. Preferflange when the member ably the bar is provided at this end with a tie abutting flange T and is so formed that the jaw E stands out of contact with the tie.

The other element D is formed so as to provide a clip J which bears upon'the upper surface of thebase flange of the rail and with a shankK adapted to extend through the opening G in the element G and provided with a lug or projection L which, when the element D is largement H of the opening, bears against the under side of the bar. Preferably the upper surface M of the lug and the surface N against which it bears are inclined with reference to the plane of the lower surface of the rail base so as to provide a wedging relation between the elements 0 and D when the latter is revolved, which draws the clip J down upon the base flange of the rail. Preferably the shank K of element D is formed with a cam 0 adapted to exert a lateral pressure against the edge of the base D is revolved. The member C is preferably formed with the arcuate Webs P and Q back of the enlargement H to take the thrust of the clip member D. Preferably also the element C is reinforced by the strengthening web R. If the element D is a casting it is preferably made with the opening S, as shown, to take care of possible shrinkage.

In fitting the device to a rail the jaw E of the stationary element C may be hooked over one edge of the rail and the shank of the clip element thrust through the opening G. By turning the clip element toward the tie the projection L engages the wedge surface N on the under side of the bar C which draws the clip J down upon the upper surface of the base flange. At the same time the cam O exerts a continually increasing lateral pressure against the edge of the flange. These engagements may be made as tight as desired by hammering on the projecting end of the clip J It will be seen that the device is extremely light, considering its strength, which is a very important consideration from the commercial point of view, as articles of this sort must be cheaply made in order to be salable.

The device is very easily applied to the rail and when properly applied will take a very reliable holdthereon. It is not likely to be disturbed.

While I have described my invention in a revolved in the en-' certain preferred embodiment, modifications might be. devised which come within the As devlces of this sort are ordinarily used with rails supported upon cross ties, the

means employed for holding element 0 in a stationary position,t0-wit in the specific embodiment of my invention the flange I,

has been designated, in certain of the claims,

as a tie abutting member. By this term I do not intend to exclude the possibility of a device being abutted or held in stationary position against some other fixed part or element of the roadbed.

I claim:

1-. A rail anchor comprising two co-en: gaging elements adapted to engage a rail on opposite sides thereof, one provided with a tie abutting member, one of said elements being revoluble and movable vertically with respect to the other element.

2. A rail anchor comprising two co-engaging elements adapted to engage a rail on opposite sides thereof, one provided with a tie abutting member, one of said elements being revoluble and movable vertically with respect to the other element, and provided with a cam which bears against one edge of the base flange of the rail.

3. A rail anchor comprising two co-engaging elements adapted to engage a rail on opposite sides thereof, one provided with a tie abutting member, one of said elements being formed with an opening and the other with a shank extending through said opening and formed with a projection which en-,

gages the under side of the first mentioned member, said projection and the surface which it engages being formed so as to have a wedging engagement.

4. A rail anchor comprising two I co-engaging elements adapted to engage a rail on opposite sides thereof, one provided with a tie abutting member, one of said elements being formed with an opening and the other with a shank extending through said opening and formed with a projection which engages the under side of said first mentioned member and with a cam which bears against the edge of the base flange of said rail, said projection and the surface against which it bears being formed so as to have a wedging engagement.

5. A rail anchor comprising two co-engaging elements adapted to engage a rail on opposite sides thereof, one provided with a tie abutting member, one of said elements being revoluble with respect to the other and provided with a cam which bears against one edge of the base flange of said'rail, and with a czltm bearing against the base flange of said ra1 6.
