RAIL ANCHOR.

Application filed October 4, 1922. Serial No. 592,322.

My invention relates to devices known as rail anchors, rail stays or anticreepers and one ot its obg'ects is to form a simple device which will prevent the longitudinal movement orn the rails ot railways.

y Other objects are tov provide a device which comprises but one piece and may be made from round or rectangular rolled bars without wasting material. Other obyects l0 are to provide a device which, while of: am-

ple strength to withstand all the stresses to which it is subjected in service, shall be light in weight; to provide a device which may be readily applied with the tools usually employed by track mechanics; and to provide for locking the device upon the rail in such manner as to prevent the accidental loosening or detachment of the device.

In the accompanying drawings, 1n which one embodiment of the invention is illustrated:

Figure l is an elevation showing the rail in section.

Figure 2 is an elevation of the rail,y showing a portion of the tie in section and av portion of the rail in side elevation.

Figure 3 is a bottom view, looking up with two positions of the device shown in dotted lines to illustrate the manner in which the device is applied to the rail.

Figure e is a perspective view of the de* vice.

Similar letters refer to similar parts throughout the several views.

A represents the rail, B the cross tie and C the rail anchor.

The rail anchor C comprises a rolled bar `one end B of which is bent over to form ajaw adapted to grip the base of the rail A at one side of the rail. Upon the other end of the rail anchor C there is formed a. portion E, which when the rail anchor C is in position on the rail extends above the plane of the bottom of the rail and provides a surface F adapted to engage the edge of the base of the rail A. The bar, of which the rail anchor C is constructed is bent downwardly from the portion E and then up.

wardly to form a portion G adapted to engage the tace ot the tie B and the end of the bar is bent over to form a jaw or arm H adapted to engage the upper surface of the base of the rail A. In bending the bar tov form the jaw D there is formed a surface I adapted to engage the edge of the rail base at the side et the rail B opposite to that `gaged by the surface F of the portion E of the rail anchor C. n i

'Io place the device in position uponthe rail it is `lirst brought to the position indi cated by the dotted lines at the right of Figure 3 with the jaw or arm H above the base of the rail A at one side ot the rail. The rail anchor C is rst moved transversely upon the rail and then longitudinally toward the tie until the tie-engaging portion Cr contacts with the tie and the jaw or arm D of the rail anchor C begins to enga-ge the top of the rail base at the other side of the rail A from that engaged by the jaw H. The rail anchor C will then be in about the position illustrated by the dotted lines at the middle of Figure 3.V Then in this position the portion E of the rail anchor C will contact with the bottom of the rail base. Force will be required vto get the rail anchor C from the position shown in the dotted lines at the middle of Figure 3. The y end of the rail anchor C at which the j aw or arm D is driven toward the rail and away from the tie,` so that the jaw D is forced onto the rail base and therail anchor C moves angularly in relation to the rail with the tie-engaging portion G held to the tie. TWhile the rail anchor C. is being thus forcibly moved angularly and transversely with relation to the rail, the portion E rides upon the bottom of the base ,of the rail A until the surface F will clear the edge ofthe bottom of the base of the rail C. The elasticity of the rail anchor C then causes the portion E to spring up into the position shown in Figures 1 and 2. The rail anchor C is then in operative position upon the rail with the arms or jaws D and -I engaging and press.- ing down upon the upper surface of the base ot the nrail A and the surfaces F and I in position to engage opposite edges of the rail base. Contact of the tie-engaging portion Gr of the rail anchor C with the tie B prevents movement of one end of the rail an- `chor C further toward the tie.

by the rail anchor C. The direction which the rail tends to move er creep is iin cheated by the arrows in lugares Q. and 3.

l of the rail to creep.

The rail anchor is so formed that after it has been placed in operative position upon the rail the grip of the jawy or arm D upon the rail base is such that should the rail move forward in the direction of the arrow it will carry with it the jaw D while the other end of the railk anchor and the jaw or arm H are held by the contact of the tieengaging port-'ion G with the tie B, so that the angular movement of the rail anchor C produced brings the surfaces I and F into Contact with the edges of the rail base and causes the rail anchor C to firmly grip the rail. Any further movement of the rail A forward in the direction 0f the arrows automatically increases the grip of the rail anchor C upon the rail and prevents further forward movement of the rail.

The engagement of 'the base of the rail A by the rail anchor C in such manner as to effelctually prevent looseningl or` detachment is made sure by the relation of the portion E to the other portions of the rail anchor C and it' will readily be seen that, even though movement of the rail in the direction opposite to that in which the rail tends to creep should' occur, the' position of the surfaces F and I or similar surfaces ofthe rail anchor C at opposite edges ofthe rail base will ensure retention of the rail anchor in such position upon the rail base that` so soon as movement inthe direction of the arrows is' Y again. set up the rail anchory C will again automatically increase its grip upon the `rail sufficiently to eifectua'lly resist the tendency It will valso be readily seen thatl the rail 'anchor C may be readily fashioned from a vice to bel made much lighter than would be practicable werey cast material necessary and at the same time there is the advantage of greater uniformity in strength which rolled steel has as compared with malleable iron or steel castings. Lightness brings also the additional great advantage of lowered cost of transportation. c

It will be obvious that rolled material of different cross sections might be utilized for the manufacture of the device and that changes in the form, proportion and minor details of construction may be resorted to 'without departing from the principles or sacrificing any of the advantages of the inventiOn.y
