RAIL-ANCHGE.

Be it known that 1, WILLIAM A. WALKER, a citizen of the United States, residing at Racine, inthe 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 a rail anchor, sometimes called a rail-stay or anti-creeper, of the type which provides two relatively movable jaws, one on each side of the rail, the lateral grip of which jaws on the rail is increased by the tendency of the rail to creep, so that such tendency is checked thereby; and the invention has for its object to provide a new and improved construction for a rail anchor of this sort which includes simple and cilectivc means for preventing the rail anchor from becoming loose on the rail, either because of the vibration of the railor its tendency to rebound or react in the direction opposite to that of the trains after the latter have passed over the rails,

or from other causes.

The invention in a preferred embodiment isillnstratcd in the accompanying drawings, wherein.- p I Figure 1 is a perspective view of the rail anchor of my invention .in position on the rail. Fig. 2 a plan view of the same. Fig. 3 a front elevation of the same showing the rail in section, and Fig. i a section taken on line et4 of Fig. 2, looking-in the direction of the arrows.

Likecharacters of reference indicate like .mrts in theseveral figures of 't-hedrawings. Referring to the drawings, A represents a rail having the base or flanges B; and C, one of the cross ties upon which the rail rests.

The rail stay consists of a tie abutting mcm-' ber l), preferably formed at one end with the depending flange (Z, and two ]LW members E and F which are pivotedto the enlarged end G of the tieeabntting member. The yaw members E and F are provided with thejaws H and I respectively, which -;extend around the opposite edges of the rail base 13 and may be of any preferred form andconstruction. The pivotal connections between the tie-abutting member and the members E andl? may be made in any desired manner, For example, I have shown Specification of Letters Yatent.

the members E and F formed with the studs J and K respectively, which extend through openings in the enlarged end G of the'tieabutting member and are riveted over at j, 7:, respectively, on the washers L and M.

With a device so constructed and with the travel of the trains in the direction indicated by the arrow in Fig. 1, the creeping of. the rail in the manner which. is well under stood, and in the direction indicated by the arrow, will cause the tie-abutting member D to be pressed tightly against the vertical face of the tie. The jaws H, I will be drawn tightly toward each other as'a result and will be caused to tightly grip the rail so that the greater the tendency of the rail to creep, the-tighter will be the grip olthe jaws. The device will thus be efficient so long as the tie-abutting member D is tightly pressed against the tie, but as is well known in this art, various influences, such for example, as the contraction of the rail under low temeratures, will tend to move the rail slightly 111 a direction opposite to the direction indicated by the arrow in Fig. 1, and a very slight movement of the rail in this direction will carry the tic-abutting member D away from the tie, and consequently will release the grip of the jaws H and I upon the rail to such an extentthat the vibration of a passing train or other causes may readily displace the anti-creeper unless some means are provided for holding the jaws in gripping ngagenient with the rail when the pressure upon tie-abutting member D is released. Various devices in the way of separate springs and ratchet teeth have been suggested but have proven unsatisfactory because of the multiplii'ration of parts and the liability to break or to have their operation interfered with by dirt, rust, cinders or the like,'and it is also understood in this art that for practical purposes it is highly desirable that an anti-creeper shall be completely assembled when shippedand of such a character that none of the parts will become separated, and there can'be no loss or wrong assembling of parts.

To rovidc means for preventing an unloosening or unclamping movement of the jaws of the anchor, I provide the jaw member F with an extension N having a tooth 0 larly formed with the vertical faces p and v the oblique faces p. This allows a relative movement between the tie-abutting member D and the extension N in the direction which gives a closer grip or clamp between the jaws H and I and the rail base B, while preventing movement in the opposite direction.

To facilitate the above action as well as to permit the detachment of the anti-creeper when desired, there is such a loose fit about the pivot K that the tooth-carrying arm N will have a sufiicient degree of vertical play to permit the tooth on the arm end either to be in engagement with the ratch teeth P or to be lifted out of engagement therewith when the device is assembled and clamped upon the rail. As shown in Fig. 1, the tooth O will be in engagement with the ratch teeth P and as there is no substantial strain upon the tooth O or the ratch teeth P, the vibration of the rail will not disengage them, but any suitable implement inserted between the tooth-figuring arm N and the body of the member I) can pry the said arm and member apart sutliciently to disengage the tooth 0 from the teeth I and thus permit of the removal of the device from the rail. It will thus be seen that I provide an automatic take-up which will not be accidentally disengaged but which can be manually disengaged whenever desired, and which avoids the use of separate springs and ratchet de vices.

The operation of the device is as follows: The anchor is adjusted to the rail so that tho tie-abutting member lies diagonally relative to the rail and a tight grip between the jaws and the rail base is effected by hammering or forcing jaw I toward the tie, the tooth O traveling over the teeth I on the upper surface of the jaw member. Obviously, the tendency of'the rail to creep forward is checked because the forward movement of the rail, and the consequent turning of the jaw members E and l! on their pivots, causes the jaws H and I to approach each other.

- The grip of the anchor on the rail forces the ()XlZQIlSlOIl N against the tie-abutting member D- and prevents looseness as between the tooth O and the ratchet. The construction of the teeth I of the ratchet and the tooth O on the extension N prevent any relative movement between the jaw member F and the tie-abutting member D in the direction of unclamping. The jaw member F and its extension N form in effect a lever having on one end a rail-gripping jaw and on the other means foi anchor.

I do not limit myself to the exact devices and constructions shown and described as modifications may be devised which would come within the scope of my invention.
