Application filed May 17, 1921.

l /iy invention relates to improvements in W anticreepers or rail anchors. The object of the invention is to provide an eiieet1ve device which shall be inexpensive to manufacture and may be constructed entirely from rolled material.

A further object of the invention is to provide a device in which the latitude in size of the rail bases to which the device may be applied is considerable; to provide a device which may be readily and rapidly W applied to the rail with the implements in general use by track hands; and to provide a device which shall be light in weight while possessing ample strength to resist the forces which must be withstood by the device in service. Other objects and advantages of the invention will be apparent from the description hereinafter given.

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

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

The anticreeperconsists of two co-engaging elements, a tie abutting rail base engaging element or clamp D and a dog or look E.

The tie abutting: rail base engaging clamp D may be formed from a rolled l d-shaped bar having a web F and two flanges and H. lin fabricating the clamp l) the two flanges are notched or slotted to form two the deso Serial No. 470,282.

jaws or arms, adapted to engage the rail base at one side of the rail; and two lugs K, adapted to engage the edge of the rail base at the side of the rail opposite to that engaged by the jaws or arms'll. The jaws; or arms I and the lugs K are preferably formed in the flanges G and H of the clamp D by a simple operation of punching or. shearing, which forms a slot in each of the two flanges G and H of the width of the rail base B and the slot is preferably given a slight downward camber or deflection as indicated in Figure 4;. The web F ofv the clamp l) is punched at L and slotted at M, to receive the dog or look E.

The dog or lock E has two arms N and O, and the arm N is provided with a lug or projection P adapted to be inserted in the opening L in the web F ofthe clamp D. 'lhpQ arm 0 of the dog or lock E is notched at In applying the device to the rail the clamp D is placed with the jaws or arms I enga in the rail base at one side 01 the rail and riven transversely upon the rail with ither flange G or H in contact with or adjacent to a face of the tie C. While being so driven to position the lugs K will ride upon the bottom. of the rail base until these lugs clear the edge of the rail base at the side opposite to that engaged by the arms or jaws i. When this position is reached the resiliency of the clamp D will spring the lugs upward into engagement with the edge of the rail base as illustrated in Figure t, The dog or catch may then be placed in posi tion by inserting the lug P of the arm N of the-dog E in the aperture L of the web F of the clamp D, and then by moving the dog E angularly, it may be brought into engagement with the upper corner of the rail base. A sharp blow with a hammer or similar instrument upon the upper end of the dog E will move the arm Q upon the rail base sufiiciently to bring the notch Q, into engagement with the upper corner of the rail base as illustrated in Figure 4:, and hold the dog E in engagement with the rail base so that both hands of the person applying the device will be free. The dog or lock E may then be driven to the final operative position illustrated in Figure 1 by the use of a hammer or any other convenient implement While being so driven the dog E pivots upon the corner S of the aperture L in the Web F of the clamp The surface R of the strongly up against the bottom notch Q is inclined at relatively small. angle to the surface T of the main portion of the arm 0 of the dog E so that the arm Q will ride upon the corner of the rail base in being forced into position and will exert strong upward forces upon the clamp D drawing the clamp D up into contact with the bottom of the rail base and stressing the clamp D so that the curved or cambered portions of the slots in the flanges and H are drawn into contact with and pressed of the rail base as illustrated in Figure 1. its the final position of the dog E is approached the surface N of the web F of the clamp D and the surface V of. the arm M of tlie oog E contact so that in the operative positi n of the parts there is sutlicient area of contact of the parts to provide properly for the transmission of the stresses to which each is subject. .l ith the parts in the op ,rative position the sides of the aperture L and the slot M in the web F of the clamp D form abiitments preventing movement of the lower portion of the dog or look E in the direction of length of the rair ant the lug l? prevents lateral disengaging movement of the dog E in relation to the clamp D. In the final operative position of the parts tli-, lugs K on the flanges G and H of the clamp D engage the edge of the rail base opposite to the arms or jaws I and prevent lateral movement of the clamp D upon the rail base. i It will readily be seen that the line of the pressure of the dog or 1001; E against the top of the rail base, both while applying vdog E and with the parts in operative positionQ )asse through the clam at tho olace I i.

of its engagement with the dog E and through the rail base at some distance in from the edge of the rail base so that with the parts in position there is no tendency for the dog or look to become disengaged from the rail. Furthermore variations in the dimensions of the rail base (to not affect the security of the engagement of the parts with each other and with the rail base, bc-' cause of the resiliency of the clamp D and the dog or look both of which are preferably constructed of materials permitting considerable change in form without permanent deformation It will readily be seen that should the rail tend to move across the tic the engagement of the flan e G with the face of the tie "ill resist such movement. Should the initial grip of the re st the forward creeping movement.

creases The certaietv of the engagement o the n Ls with eacn oth r with rail clamp D and the dog or look E upon the rail,

even though the clamp D be held as, for example in frozen ballast during such rearward movement, for the reason that the device would, n that event, operate to resist such rearv movement in a manner es:- actly similar to that in which it operates to ltwill thus be seen that after the anticreeper has once been placed upon the rail base it is positively locked in position.

it will be noted that the de'rice may he applied with either flange G or H adjacent tl e tie and that is, therefore, reversible; and the clamp D is so constructed that the dog E cannot be positioned until the clamp D has been correctly placed with the lugs K clear of edge of the, rail base opposite the aws I, so that the device cannot be incorrectly or i iproperly applied. This permite its application to be placed in the hands of the most ignorantand unskillful of traclr employees. 7

It will readily be seen that the clamp D may be easily and cheaply manufactured from a rolled bar. All that is involved in its fabrication is the cutting of the bar to length, the slotting of the two flanges to re ceive the rail base and the punching of the web. The dog or look is likewise readily manufactured from a flat rolled bar. Fig ure 5 illustrates the simplicity of the opera tion involved. In Figure 5 a portion of the bar is shown after one or more of the dogs have been made therefrom. In one operation the slot X may be punched and the bar sheared at the line *W. Movement of the bar for a distance equal to the length of one dog or look E permits the machine to punch out the slot X and shear the bar at line VJ thus forming a complete dog E. Repeating the operations for X W etc, the entire bar may be rapidly and inexpensively formed into dogs or locks E.
