mun ANCHOR.

Application filed August 2, 1923, Serial No. 655,240. Renewed December 8, 1924.

To all icliom it 'may concern Be it known that I, HARoLn G. IVAnn, a citizen of the 'United States, residing at Park Ridge, in the county of Cookand State of Illinois, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specification.

My invention relates to rail anchoring devices generally, and inoie particularly to one-piece anchor devices of the general type consisting of a rail base embracing yoke adapted to grip the upper and low-cr 'sur-A faces of the base portion of a railway rail. .f

Rail anchors of the general'type to which formed by bending a metal bar to vform jaws for receiving the upperinclined surfaces of a rail base at opposite sides 'of the rail and to provide a portion intermedi-ate said jaws adapted to bear against the bottoni'surface of the rail base. Such anchors are applied to their operative position by driving them transversely of the rail; the jaws and said intermediate portions being so -formed that the transverse movement, forcing one jaw upon the inclined surface ofthe rail base, distorts the anchor and thereby produces a spring grip on opposite edges of the rail base.

In order to obtain maximum efiiciency of anchorsvof the above general type (the anchors relying upon their resiliency to maintain the desired grip on the rail), it is necessary that they be manufactured accurately and be subjected only to a limited distortion during their application to a rail. VSuch accuracy is difficult to maintain in the manufacture of anchors of the configuration heretofore used. li`urtherinore, efiiciency of such anchors properly formed is o fteii inipaired by excessive distortion resulting from improper application of the anchors to their rail grinning position.

A primary object of my invention is to provide a Irail anchor of the above general type, that may be more easily and efiiciently manufactured, made with a higher average of perfection as to its rail grippingr portions, and which will take a more reliable hold on the rail base than other devices of this character.

The specific objects contemplated by this invention include the provision of a `onemy invention appertains are ordinarily and such other piece rail anchor device having one or more of the improved constructions as'follows: A rail anchor having -such configurations as will overcome the above mentioned and other incidental objections encountered inV the ,y

the rail in a direction to remove it; and anV anchor provided 'with means for indicating itsproper 'gripping position onr a rail and for preventing movement of the anchor beyond its 'intended lapplied position so as to lavoid excessive distortion of the anchor.

during its Vapplication to a rail.

f lhe invention further consists in such otlieihnew and improved constructions as' will be hereinafter described and claimed, for carrying out the above stated objects,

incidental objects as will appear from the following description.

The invention is illustrated in certain'preferred embodiments in the accompanying drawings, \vhereii1- i Fig. 1 is a side view in elevation of a rail anchor constructed in accordance with my invention, applied to its operative position on a rail base; i

Fig. 2 is a similar view in elevation of the anchor applied in its initial position on the rail and before the anchor is subjected to any appreciable stress.

Fig. 3 is a plan view of the structures illustrated iii thepreceding figures, and

Fig. 4 is a view similar to Fig. 1, illustrating a modified embodiment of myA invention.

Like characters of reference designate like parts inthe several figures of the dra-wings.

In the drawings, l() esignates the lower cross-ties on which the rail is supported.

In Figs. 1, 2 and '3 of the drawings, I have shown my improved rail anchor as consisting of a yoke member 12 made of a steel bar, the ends offwhich are bent over to form hook- shaped jaws 13 and 14. The under surface of the jaw 13 is provided with an abrupt shoulder 15 adapted to abut against one edge of the rail base. tion 16 of the under surface of the jaw 13 general type of anchor V.

The por- 4 preferably inelines upwardly toward the eX- tremity of the jaw at an angle slightly greater than the inclination of the upper sur-` face of the rail base. This construction permits the application of the anchor to a rail made within the allowable variations in thickness -of its base flanges, and at the saine gime insures engagement of that portion of the jaw adjacent the shoulder 15 with the upper surface of the rail base. The jaw 14 is formed with an abrupt shoulder 17 which isl preferably formed at the termination of the bend of said jaw andabuts against the cient length to permit the bend 12a to' be made with a relatively large radius, thereby minimizing the weakness resulting from the stretching and swaging of the metal at this point. Furthermore, the arrangement of the seat 19, midway between the shoulders 15 and 17, makes it possible to form an anchor with relatively largev jaws with a minimum amount of metal, equalizes the pressure ofthe jaws on opposite edges of the rail base and insures a substantially uniform distribution of the distortion of the anchor during its application to a rail.

In applying my improved anchor to a rail,

the jaw.13 is first hooked over one edge of the rail base, and the jaw 14 positioned adjacent the opposite edge, substantially Vas shown in Fig. 2. The yoke may then be forced in the direction of its length toward the right of Fig. 2, so as to force the cam surface 18 over the upper corner of the adjacent edge of the rail base. The cam surface 18, being forced over the edge of the rail, distorts the yoke and thereby effects a substantially equal pressure of the jaws on the upper surfaces of the rail base and the seat 19 bears against the bottom surface thereof at the center. When the anchor is forced home, the shoulder 15 snaps down over one edge of the rail, and the shoulder 17 abuts against the opposite edge of the rail, thereby locking the anchor in its applied position.

The inclination of the lower surfaces of the jaws insures a firm engagement of the jaws with the rail base adjacent the shoulders 15 and 17 This construction in-- ing the` application of the anchor to the rail,

sures that the shoulder-15 will snap down over the edge of the rail and that both shoulders will properly function to lock the anchor against movement in either direction transversely of the rail. 'T he shoulder 17, in addition to providing a stop to prevent the anchor being driven beyond its proper position, provides suitable means for giving the workman a visual indicationas to when the anchor is nearing its applied position.

In Fig. 4; I have shown a modified form of anchor in which the gripping action of the anchor is effected by reason of a differential leverage of the jaws in addition to the cam action as shown in the preceding figures. This modification consists generally of a yokel formed with a relatively large hook shaped jaw portion and a smaller jaw portion for engaging opposite edges of a rail base and with an inverted V-shaped portion intermediate the jaws for bearing against the under surface of the rail base, such anchor devices being adapted to be applied to a rail by first hooking the relatively large jaw over one of the fianges of the rail and swinging the other end upward until the end of the smaller jaw clears the upper edge of the rail base flange, in which position the V-shaped portion of the ra-il anchor bears against the under surface of the rail. The smaller jaw is then driven upon the other flange of the rail base whereby the anchor is slightly distorted by reason of-the different distances between the rail engaging scat of said V-shaped portion and the rail engaging'surfaces of the.jaws and effects a spring grip of the devicev on the upper and lower surfaces of the rail base. This gripping action may be and preferably is increased by forming the under surface of the jaw portion 27 at aslightly greater angle than that of the under-surface of the jaw portion 28.

In applying a device of this general character the workman often drives the, anchor beyond its intended normal position, thereby subjecting the small jaw and other parts of the anchor to greater distortion than is intended. This is particularly true in connection with the type of anchor in which the end of the larger jaw is recessed or otherwise formed to provide an abutment, or shoulder. adapted to assume a position Vagainst thev vertical edge of the rail base blow intended to drive it home often forces vit upon the rail to a point bevond its iutended position. lilxcessve vdistortion of rail anchors of the above character impairs their resilient rail-gripping qualities, aml makes them unsuitable, when removed, to

be applied to another rail. I overcome'the above mentioned and other incidental objections to anchors of this general type, by providing the under surfaces 2:326 of both jaws 27, Q8 of the anchor with relatively abrupt shoulders 2S) and 30 adapted to abut against opposite edges of the rail base. The said lower surfaces of the jaws preferably incline upwardly toward the extremities of the jaws at a greater angle than the inclination of the upper surfaces of the rail base;`

thereby insuring a firm engagement of the jaws with the rail adjacent the shoulders Q9 and 30.

I do not claim specificallyherein the modified construction shown in Fig. 4 of the drawings, nor do I claim herein the method employed in the manufacture' of the anchor devices herein shown. The modified form of anchor shown in Fig. 4 is described and claimed specifically in my copending divisional application, Serial No. 704,676, and the method of manufacturing the. anchor devices herein shown is described and claimed in my copending divisional application, Serial No. 708,493.
