RAIL-ANCHOR.

Specification of Letters Patent.

Patented Nov. 16, 1920.

Application filed May 2, 1918. Serial No. 232,075.

T 0 all whom it may concern:

Be it known that I, HORATIO G. GILLMOR, a citizen of the United States, residing at Washington, in the District of Columbia, have invented a new and useful Improvement in Rail-Anchors, 01: which the tollo wing is a specification accompanied by draw ings.

This invention relates to devices for preventing longitudinal or creeping movement of rails commonly known as rail anchors, rail stays or anticreepers; and an object of the invention is to provide a device which will effectually grip and hold the rail, be simple in construction and be easily and quickly applied with the implement usually employed by track hands.

A further obj ect is to provide an improved rail anchor in which the surface of contact between the rail and the anchor is made large by gripping engagement with both the base and the head of the rall.

A further object is to provide for resilieney which shall take up and prevent looseness due to wear, differences in expansion of the metal of the anchor and of t ie rail or to other causes; and to provide a rail anchor which shall be free from liability to interference with its eiiicient action by the ballast.

Further objects are to provide a device which is reversible and may be applied with either side to the tie, thus facilitating application and avoiding the possibility of orrors in amalication; and to provide a rail anchor which, while having the necessary strength, will be light in weight, to secure the advantages of low cost to manu'hicture and reduced cost in transportat'on to the point of use.

The invention is illustrated in one embodiment in the accompanying drawings in which Figure 1 is an end elevation of the rail anchor applied to a rail, with a portion of one tie in section.

Fig. 2 is a section through the rail and the device at the plane indicated by. X in Fig. 1.

Fig. 3 is a side elevation of the device with the rail and a portion of the transverse element in section, illustrating the IBQthOCl of applying the device.

Fig. 4 is a view of the device applied to the rail, looking up from below the rail;

In the drawings similar letters apply tov like parts in the several views.

Referring to the drawings A represents a rail oi: the usual type having a head l3 and a base flange The rail rests upon a tie D and others similar, not shown. The rail anchor comprisesa transverse element E and a vertical element F. The member is provided at one end with a jaw t arpanged to grip one side oi": the base flange b and, at the other end, with portions H, arranged to engage the edge of the base flange C at the opposite side of the rail; and a portion I, arranged to engage and in terloclr with the member F. each end of. the member E there are tie engaging pore tions K, arranged to transmit to the tie the thrust of the member E. The transversely extending portion of the member E is, when this member is in its normal unstressed condition, cambered, curved or bent down wardly; so that, when the member E is in place before the member F is placed in ifinal position, the free end of the member E will stand away from the rail bottom as at L in Fig. 3. The member F is former at M with a portion arranged to engage the portion I of the member E; and has also, at N, a portion arranged to engage the upper and lower corners of the base flange (3. The member F has also two flanges O, the edges P of which engage the upper surfs. e of the base flange C. The upper end of the member F is formed with surfaces 131, to engage the lower corner of the rail head B when forcing the member F into position, and S, to engage the under surface of the rail head B and lock the parts in position.

To place the device, the member E is first placed with the jaw G in engagement with one side or" the base flange C and then driven transversely upon the rail untii the portions H at the other end of the member E are in position to be drawn upwardly into engagement with the edge of the rail base C. The downward inclination or cambering of the member E causes the end of the member C and the portions H, opposite the jaw G, to stand away from the bottom and edge of the rail base C. When the member E has been forced to this position it. is possible to insert the lower end of the member F between the portion 1 of the member E and the edge of the rail base C and to engage the portion L of the member F with the portionli of the member E. The member F will in this position have the edges P of the flange O in engagement with the upper corner of the rail base (3 and, 7

of the member E engaged by the member F and brings the surface R of the member F.

into contact with the lower corner of the rail head. To bring the part F to the final operative position, illustrated in F igs. 1, 2 and 4, the upper end ofthe member F is driven or-otherwise forced toward the web of the rail A. Angular movement of the member 1: is produced with the upper and lower corners of the rail base C forming a bearing upon, which the surface N of the member F moves, while the surface R of the upper end of the member F, engaging the rail head B, produces a cam action which forces the member F downwardly. As this movement is continued the surface Scomes into engagement with the under surface ofthe rail head J5 and the edges P of the flanges O of the member F are forced down upon the upper surface of the rail base C; and, at the same time the end of the member E opposite the jaw G is drawn up so that the portions H engage the edge of the rail base C and the bottom of the rail base C is engaged across the rail base by the upper surface of the member E. The member E is thus caused to grip firmly the opposite sides of the rail base 0 and to press upwardly with a pressure, 'which is distributed across the bottom of the rail with a pressure the amount of which is determined by the elastic strength of the material of which the member E is constructed. In the final position of the parts F1 and F, the member F is wedged in between the heat 13 and the base C of the rail A and the base 0 is gripped between the jaw G and the body of the member E, at one side of they rail and by the portions H at the other side of the rail, and the body ofthe member E" is gressed upwardly upon the rail bottom. Vhen theparts are in their final position the member E exerts a strong pull clownwardly upon the member F "and this pull tends to produce angular movement of the member F about the rail base C. The engagement of the surface S of the member F with the under side of the rail head however effectually locks the parts against any reverse movement and insures that there will be no accidental loosening.

It will be seen that the large area of contact. of the parts with the rail and their pressure upon the rail gives great holding of the rail upon the device without movement of the rail in relation to the device.

The direction in which the rail tends to creep is indicated by the arrow in Fig. 1 and is referred to as forward; and, if the initial grip of the parts should not be sufiicient to hold the rail, once the portions K of the member E have come into contact with the tie D, and some slight movement of the rail A in relation to the member E occurs, the upper end of the member F will be carried forward with the rail A and the member F will assume a slightly inclined position, shown by the dotted lines in Fig. 1. This movement will increase the wedging action of the member F between'the head B and base C and also increase the upward pres sure of the member E upon the rail bottom. The tendency to further creeping movement of the rail A is thus self checked.

It will beevident that the device may be applied to the rail with either set of tie abutments K adjacent the tie D and that it may therefore be applied with the vertical member F either inside or outside the rail. It will also be apparent that the device may be easily and quickly applied by unskilled men using only the implements ordinarily placed in the hands of track mechanics. It will be apparent also that by arranging the ties D so that the tie abutments K on opposite sides of the member E are adjacent the op posing faces of two ties, the device will be effective for preventing creeping in either direction.

While I have described my invention in one embodiment, it will be understood that changes in form, construction andarra'nge ment of parts might be made without departure from the spirit of the invention. Therefore, I do not wish to be understood as limiting the invention to the exact construction described except so far as so limited by the express language of the claims.
