RAIL-ANCHOR.

Specification of Letters Patent.

Patented May 3, 1921.

Application filed January 9, 1918, Serial No. 211,011. Renewed October 15, 1920. Serial No. 417,280.

T 0 all w 7mm it may concern Be it known that I, HORATIO Gr. GILLnon, a citizen of the United States, residing at Vashington, in the District of Columbia, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

My invention relates to a device for preventing the longitudinal creeping of the rails of railways. Such devices are commonly called rail anchors, rail stays or anticreepers. The invention relates particularly to a device in two parts in which one of the elements is a shoe pressing against the rail bottom and the other resilient and strained when the device is applied to the rail so that retrograde movement of the rail, vibration or other accidental cause would not loosen the grip of the device upon the rail and thus diminish its holding power.

The primary object of my invention is to provide a rail anchor comprising a plurality of co-engaging elements which together grip the rail and are so constructed and arranged that forward or creeping movement of the rail produces the co-action of the elements whereby the tendency of therail to creep is self-checked, one of the elements being subjected to opposing torsional forces, whereby the grip of the device upon the rail is affected.

A further object of the invention is to provide a rail anchor of the type in which a rail base engaging shoe is held to and pressed upon the rail base by a transverse bar which is reversible and may be applied with either end engaging the rail base engaging shoe. Reversibility of the transverse bar in a device of this character is an advantage in that it simplifies the application of the device to the rail and reduces the possibility of incorrectly applying the device.

A further object of the invention is to provide a rail anchor which will be inexpensive to manufacture, strong and durable and at the same time light in weight. Weight is an important consideration both in the cost of manufacture and the cost of transportation.

The invention is illustrated in one embodiment in the accompanying drawings in which:

Figure 1 is a side elevation showing the device in operative position upon the rail a portion of which and a cross section of a portion of one tie are shown.

Fig. 2 is an elevation showing the rail in cross section.

Fig. i is an elevation, showing one ofthe positions assumed by the parts while the device is being applied to the rail, the rail being shown in section.

Fig. 5 is av side elevation of the rail base engaging shoe.

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

Referring to the drawing, A designates a railroad rail having a base flange B resting upon and supported by cross ties, one of which is designated by C.

The rail anchor illustrated consists of two co-engaging elements, a tie abutting rail base engaging element or shoe D and a transverse element or yoke E.

The tie abutting rail base engaging element or shoe D may be formed from a rolled T shaped bar having a rib F. This bar cutto suitable length has one end turned to form the tie abutting portion G. A portion of one edge of the body of the bar is flanged as at H to form a shoulder adapted to engage one vertical edge of the rail base B. A portion of the rib F is cut away near one end of the shoe D so as to form the seat I and a shoulder or face K and a shallow shoulder R.

The transverse element or yoke E is adapted to extend around the base of the rail and has an arm or j aw L adapted to engage the upper surface of the rail base B at one side of the rail and a like arm M adapted to engage the upper surface of the rail base B at the other side of the rail. The two ends of the transverse element or yoke E are alike so that the device may be applied with either end engaging the shoe D. The arms L and M are at an angle to the body of the transverse element or yoke E and the transverse body portion of the yoke E is bent at N and at 0 so as to form portions either of which is adapted to engage with the, shoulder K on the shoe D. In the drawing, Fig. 3, the shoulder N is shown so engaged with the shoulder K of the shoe D.

In applying the device to the rail one arm either L or M is hooked overthe rail base and the yoke E is moved transversely until the other arm may be brought into engagement with the top of the rail base at the opposite side of the rail. The position of the yoke will then be about as indicated by the dotted lines in Fi 3. lVith the yoke in this position the shoe D is placed with the shoulder K engaging the portion N of the yoke E and the yoke and shoe move forward (that is in the direction indicated by the arrow in Fig. 1) until the tie engaging portion G of the shoe D is in engagement with the face of the tie C, and will occupy about the positions shown in Fig. 4. The parts, when in this position in relation the one to the other are loose so that they may be readily moved upon the rail. With the shoe held up against the rail base by the person making th application of the device, the yoke E will be out of engagement with the seat I as illustrated in Fig. 4. The yoke E is then moved transversely and angularly upon the rail so that the portion P of the yoke E is brought into contact with the portion H of the shoe D and the arms L and M of the yoke E are moved upon the rail base. The angular movement of th yoke E brings the arms L and M to higher positions upon the top of the rail base B and causes the yoke E to be drawn vertically. This movement brings the body of the yoke E into contact with the seatIupon the shoe D and further angular movement of the yoke E upon the rail base sets up opposing torsional forces which act upon the yoke E and cause the yoke E to exert a strong vertical pressure of the yoke E upon the shoe D, causing the shoe D to press upwardly upon the rail base B and the arms L and M of th yoke E to press downwardly upon the upper surface of the rail base B. The yoke E and shoe thus co-act to exert strong vertical gripping pressures upon the rail base B. The angular movement of the yoke E upon the rail base also causes th yoke E, the portion P of which is engaging the portion H of the shoe D, to exert a pull transverse to the rail whereby the portion H of the shoe D is caused to press strongly against the vertical edge of the rail base. It will thus be seen that the rail base B is firmly gripped both transversely and vertically between the yoke E and shoe D when the parts are in the operative position shown in Figs. 1, 2 and 3. The angular movement of the yoke E necessary tothe tightening of the parts upon the rail may be effected by driving the portion Q of the yoke E forward with a maul or some other suitabl instrument.

It will readily be understood that if, with the parts in the operative position, shown in Figs. 1, 2 and 3, there should be any tendency of the rail to move forward it will be resisted by the tie which is in engagement with the tie engaging portion G of the shoe D. Generally the forced angular movement of the yoke E in applying the device will have produced such gripping of the rail as will effectually prevent forward movement of the rail under creeping stresses. Should this, however, not be the case, it will readily be understood that if creeping movement occurs the arm M of the yoke E will be carried forward with the rail so that further angular movement of the yoke E will be produced, and this further angular movement will automatically increase both the transverse and the vertical gripping pressure exerted by the yoke E and the shoe D upon the rail base, so that the creeping movement will thus be selfchecked.

' The yoke E is resilient and strained during the application of the device being subject both to torsional strain and to vertical bending strain. It will thus be evident that should there be any reverse or backward movement of the rail the parts will be carried with the rail and the tie abutting portion G of the shoe D will be drawn away from engagement with the face of the tie C. If, during such reverse or backward movement of the rail the tie engaging portion G of the shoe D should be held, as for example by being frozen in the ballast, the shoulder R upon the shoe D will effectually hold the shoe D and the yoke E so as to prevent such movement of the shoe D with relation to the yoke E as would result in disengagement of the parts and the resiliency of the yoke E will prevent the gripping pressures of the parts upon the rail base for being affected by such reverse movement. The resiliency of the yoke will likewise prevent any loosening of the parts upon the rail base by reason of vibration of the rails or any of the other accidental causes tending ordinarily to produce loosening of devices of this character upon the rail.

While I have shown and described the invention in one embodiment, modifications might be made without departure from the principles of the invention, therefore, I do not wish to be understood as limiting the invention to the particular construction, arrangement and devices shown and described except so far as these limitations are specifically set forth in certain of the claims herein.
