To all whom it may concern:

Be it known that I, J oI-IN A. BODKIN, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Rail- Auchors, of which the following is a specification.

My invention relates to a device for preventing the longitudinal movement or creeping of the rails of a railroad, devices of this sort being ordinarily called` rail anchors, rail stays or anti-creepers; and the invention has for its object to provide a new and improved construction for devices of this character.

The principal object of the invention is to provide a rail anchor in which one of the Jaws which grip the rail on opposite sides 1s in the form of a rotating cam, which bears against the rail flange in such a manner that any tendency on the part of the rail to creep will be checked by the increased gripping pressure brought about by the rotation of the cam. lVhile the invention will be illus trated and described in constructions involving the use of such a cam on one side of the rail only, the ordinary jaw being employed on the other end of the stay, it is obvious that the cam arrangement could be used on each side of the rail, if desired.

The invention has for a further object to provide means for locking the cam against reverse rotation, thereby preventing the engagement between the stay and the rail from being loosened by the slight reactive movement, or rebound, of the rail, which occurs after the train has passed over lthe same,

and which prevents a loosening of said en enlarged, of the cam. Fig. 4L an inverted plan view of the same. Fig. 5 a fragmentary plan view illustrating a modified structure. Fig. 6 a section taken on line 6-6 of Fig. 5. Fig. 7 a fragmentary plan view illustrating a different embodiment of the ideas involved in the two preceding figures. Fig. 8 a vertical section illustrating a somewhat different form of device. Fig. 9 a plan view of the cam shown inl Fig. 8. Fig. 10 an inverted plan view of the nut. Fig. 11 a view in perspective of the locking device. Fig. 12 a plan view illustrating another modification. Fig. 13 a section on line 13--13 of Fig. `12.

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

Referring first to Figs. 1 to 4 inclusive, which show the simplest form of the invention, A represents the rail, having the usual flange B, and C one of the ties supporting the rail. The stay or anchor consists of a body part or bar D, which extends under the base or iange B of the rail and which abuts against the tie. In order to get a firm bearing upon the tie, the bar may beprovided with the depending fiange E. The rail is gripped between the rotating cam F on one end of the bar D and the jaw Gr on the other end. The latter may conveniently, though not necessarily, be integral with the bar. The cam F consists preferably of a circular disk eccentrically mounted on a bolt H with its vertical edge f, which is preferably serrated or roughened, bearing against the edge of the rail flange. The cam is held to the body of the stay D by a nut I. A washer z' may be interposed between the nut and the cam. Preferably, the cam is formed with an overhanging rim f and the edge of this rim may be roughened in order that the stay may be tightened on the rail by hammering.

It will be understood that 4when the stay has been clamped upon the rail flange with the abutment E against a tie, on the side of the tie from which the trains approach, the tendency of the rail to creep under the action of the train will be resisted-by the cam, which, by rotating with the advance of the CII rail, causes the rail stay to grip the rail with additional force. y

In Figs. 5 and G I have shown a modification affecting only the structure of the cam. In this construction the eccentrically placed opening f2 of the cam F is threaded, the bolt I-I being correspondingly threaded. The nut of the previously described construction may, therefore, if desired, be dispensed with. In this form of device I have shown means for preventing a reverse rotation of the cam. It has been found that rails have a tendency to react or rebound slightly after a train has passed over them the rebound being, of course, in the direction opposite to the creep of the rail. This tendency, slight as it is, is sufficient to loosen the grip upon the rail of certain types of rail stay. To.overcome this tendency in the stay of my present invention, I provide locking means which permits a free rotation of the cam forward (relatively to the rail), while preventing a reverse movement. For example, a recess J, wider at one end than at the other, may be formed upon the circumference of the opening f2 and a threaded pin K inserted in the wider part of this recess. Supposing the tendency of the rail to be to creep in the direction indicated by the feathered arrow in Fig. 5, the pin K will allow cam F to rotate with the advance movement of the rail in a direction to increase the distance between the opening f2 and the edge of the rail flange while locking the cam from reverse rotation.

In thc drawings the pin K is shown as resting in the wider end of the recess J, so that the pin K will freely rotate when the cam is turned in the direction indicated by the arrows, but when the cam is turned in the opposite direction the pin K will be brought in contact with the narrower end of the recess J, which is of such dimension that the pin K will be tightly wedged against the central bolt H, so as to prevent such reverse rotation of t-he cam.

The top f3 of cam F is shown in Fig. 5 as hexagonal in form. This is to allow the caln to be tightened by a wrench. The modification illustrated in Fig. 7 shows the top f* of the cam as circular, as in the construction of the first four figures. Otherwise, the device of Fig. is the same as that of Figs. 5 and 6.

In Figs. S to 11 inclusive, I have shown a further modification involving, however, the same general principles. The cam F 2 in this case turns upon a sleeve L which surrounds the bolt I-Ig. The nut I2 is provided with the notches M on its under surface, and the cam has corresponding notches N. Between the nut and the cam is interposed a spring lock O with its ends o, 0 turned in opposite directions. The engagement of the spring lock with the notches M and N is such as to permit the cam to be turned in the direction of the Creep of the rail, but to prevent reverse rotation.

A somewhat different form of device is shown in Figs. 12 to 16 inclusive. I'Iere the tie abutment F13 is shown as on the opposite end of the stay D3 from jaw G3. The position of the abutment, however, is not essential to any particular form of device. The cam F3 of Figs. 12 to 16 inclusive, turns on a sleeve L3 on the bolt I-IS. The under side of cam F3 is provided with the notches M3 and the upper surface of the stay with the notches N3. A spring lock O3, similar to the spring lock of Fig. 11 may be interposed between the cam and the body of the stay. The parts are held together by the nut I3.

I do not limit myself to the particular forms, constructions and devices shown and described, as modifications might be devised which would come within my invention as defined by the claims.

I claim:
