RAIL-ANCHOR.

Specification of Letters Patent.

Patented ar. 18, 19159.

Application filed November 7, 1916. Serial No. 130,050.

To all whom it may concern:

Be it known that I, HonA'rio G. GILLMon, a citizen of the United States, residing at Washington, 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 pre-- venting the longitudinal movement of the rails of railways, generally known as creeping, and devices of this sort are commonly called rail anchors, rail stays or anticreepers. The principal object of the invention is to provide a device of this character which will be very simple in construction, inexpenseive to manufacture and easily applied, using the tools ordinarily employed 'by railway track workers.

Further objects of the invention are to provide a device which will take a very firm and reliable grip upon the rail and shall have efficient means for maintaining the grip of the device upon the rail as against disturbing influences such as vibration. contraction and expansion of the metals due to changes of temperature and tendency of the rail to move at times in a direction the reverse of the direction in which the rail would move under the forces causing creeping.

The mvention has for further objects such other new and improved constructions, arrangements and devices relating to devices for preventing the longitudinal creep of railroad rails as will be hereinafter described and claimed.

A preferred embodiment of the invention is illustrated in the accompanying drawings, in which I Figure 1 is a view of the device applied to the rail, looking toward the tie and showing the rail and one of the parts of the device in section.

Fig. 2 is a side elevation of the device in operative position on the rail.

Fig. 3 is a view of the device, looking away from the tie showin one of the positions of the parts while being applied to the rail, illustrating the method of applying the device.

Fig. 4 is a perspective view of the dog or pressure producin part.

Fig. 5 is an en view of the transverse part of the device.

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

Referring to the drawings A represents a railroad rail havin a base flange B and C a portion of one o the ties, upon which it rests and is supported.

The device of my invention preferably consists of two parts or elements D and E shown separately in Figs. 4 and 5, respec- 'tively.

The element D which may be made from a flat bar or plate, is constructed to be applied to the rail and the element E to produce a vertical pressure and cause the rail tip be gripped between the elements D and forms an arm having a surface G, which, with the device in operative position on the rail, engages and presses down upon the is also provided with a projection N, which I engages a wrench when removing the device from the rail.

The element E is applied transverse to the rail and has at one end a jaw C adapted to engage the base flange B of the rail A at one side of the rail and at the other end has shoulders P which are adapted to engage the vertical edge of the rail base B opposite the jaw O. The portion Q, of the element E is curved as shown by the dotted lines in Fig. 2 and illustrated more fully in Fig. 5, so that the normal condition of the element E presents a COIICiWB surface to the rail bottom adjacent, and for some distance in from, the shoulders P. Projecting from the portion Q of the element E, downward, there is a portion R, which has a bearing ortion S between two projections or guid- 1ng flanges T. Between the jaw O and the shoulders P the element E has a portion U adapted to engage a-face of the tie C. The jaw O and other portions of the element E may be strengthened by flanges V.

In dotted lines in Fig. 1 there is indicated a wrench for removing the element D when it is desired to remove the device from the rail.

In applying the device to the rail the ele ment E is applied transverse to the rail with the jaw engaging the base flange B of the It is provided with a portion F which rail A, at one side, and the element E is then forced transverse to the rail until the shoulders P will be in a position to engage the vertical edge of the base flange B. For rails which are of normal width of base or of less than normal width (normal width referring to the standard designed width of base for a'railof any size) when this position is reached there will be a narrow space Y between the vertical edge of the rail base and the throat of the jaw O, as illustrated in Figs. 1 and-3. If the rail is wider on the base than the standard designed width of the rail, the element E may have to be forced onto the base flange B until there will be no space between the throat of the jaw O and the vertical edge.of the base flange B. In this way considerablevariatlon in dimension of the base flange B from the designed dimensions for any given size of rail will still not prevent the proper application of the device to the rail. When the element E is in the position in which the shoulders P may be brought into engagement with the edge of the base flange B, the elen'ient D is placed with the arm F engaging with the rounded surface H the upper surface of the base flange B and the surface M of the portion K engaging the bearing S between the guiding flanges T of the element E and is forced transverse to the rail until the surface I contacts with the edge of the rail base flange B between the shoulders P. In this way a vertical stress is ex erted upon the element E the first effect of which is to draw the end of the element E upward sothat the shoulders P are brought into engagement with the edge of the base flange B so as to hold the element E in position. This position of the parts during application of the device is illustrated 'in Fig. 3 and with the parts in this position the portion Q of the element E may contact with the rail bottom immediately adjacent the shoulders P but will stand away from the rail bottom about as indicated by the dotted lines in Fig. 2. The element D is now forced to its final position by forcing the arm K, by driving with a hammer or maul or in some other suitable manner, to-

ward the rail; and, during this movement of the element D, the arm F rolls on the surface H on the upper surface of the rail base B until the surface G comes into c'ontact with the upper surface of the rail base plane transverse to the rail by the guiding projections or flanges T until the surface L of the element D engages the bearing S of the element E fully. The effect of this forced movement of the element D is to put,

further vertical stress upon the rail and the element E and, under this stress the portion Q, which normally presents a surface conthis way the element E is made to bear with increasing pressure upon the rail bottom and the pressure of the element E upon the rail base B is distributed over the whole of the portion Q and for a considerable distance away from the edge of the rail base B. The final operative position of the parts of the device upon the rail is illustrated in Figs. 1 and 2 and it will be readily seen that, with the parts in this position, the de vice is effectively looked upon the rail and the rail firmly and reliably gripped by the device. The arm F of the element D cannot be disengaged from the rail base ex-, cept by movementof the element D in a direction the reverse of the movement in applying, which' movement is opposed by the weight of the element D and by the great friction opposing such movement.

When the rail moves under forces producing creep, it carries the device with it until the portion U of the element E-comes in contact with the face of the'tie C when the engagement of U with the tie, which is held in the ballast and, therefore, a fixed portion of the roadbed, prevents further forward movementthat is, movement in the direction of creeping, indicated by the arrow in Fig. 2. If for any reason the grip of the device upon the rail should not be sufficient to withstand the forces tending to produce creep after the portion U of the element E is in contact with the tie and some movement of the rail in relation to the .element E movement will cause a slight cant-ing of the element D as shown in dotted lines in Fig.- 2, the arm F being carried forward with the rail and this slight canting or angular movement of the element D will automatically increase the grip of the parts upon the rail so that the creeping will be self checked.

It will be readily seen that the part E is effectually looked upon the rail base B by the engagement of the jaw O and the shoul-v ders P with opposite edges of the base flange B and the engagement of the element D with it and the'rail base B and the resiliency of the portion Q of the element E and of the element D prevents these elements from being affected by vibration or other accidental cause. Moreover, should the rail be caused by changes of temperature or other reason to move backward, such reverse movement would be without effect upon the grip of the device upon the rail even though the element were held in frozen ballast or otherwise prevented from moving in the reverse direction with the rail.

It will also be readily understood that the device can be applied to the rail using only a maul or other tool usually carried by track were produced by the creeping forces such V which the element D was forced into position, may-readily be produced and the element D removed, which will permit the element E to be at once removed.

While the invention has been shown and described in a preferred embodiment, it will be understood that 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 exact constructions and arrangements shown and described except so far as the claims are specifically so limited.
