PATENT HAROLD G. 'WARR, OF PARK RIDGE, ILLINGIS, fiSSIGNOR-TO THE F. 80 M. COMPANY, OF CHICAGO, ILLINOIS, A. CORPORATION OF ILLINOIS.

RAIL ANCHOR.

Application filed June 25, 1923. Serial No. 647,645.

To aZZ whom it may concern:

Be it known that I, HAROLD G. VVARR, a citizen of the United States, residing at Park Ridge, in the county of Cook and 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 anchors, and has for its primary object the provision of an improved rail anchor which will maintain a firm grip on a rail, which may be conveniently applied to or removed from a rail when desired, and which will it rails having base flanges of different sizes.

A further and more specific object oi the invention is the provision ct an improved two-piece anchor device consisting of a jaw member and a key or wedge member which together grip one or both edges of a rail base, which are so constructed that either or both members may be conveniently formed from sheet metal, and which when applied to a rail will provide a resilient interlocking engagement of the members, one within the other, so as to maintain the key or wedge member in its applied wec ging position.

The invention further consists of the new and improvedconstructions and arrangement of parts, hereinafter described and claimed, for carrying out the above stated objects, and such other objects as will appear from the following description of the embodiments of the invention illustrated in the accompanying drawing.

In the drawing Fig. l is a face view, partly in elevation and partly in section, of a rail anchor de vice constructed in accordance with my in vention, showing the same applied to the base flange of a rail.

Fig. 2 is a plan view in elevation of the rail anchor shown in Fig. 1, the outline of the rail base for the purpose or clearness being illustrated in dot-and-dash lines in this figure.

Fig. 3 is a cross-section taken on line 33 of Fig. 1.

Fig. a is a view similar to Fig. 1 illustrating a modified embodiment of the invention; and I r i Fig. .5 is asectio'nal plan view,- t-aken on line 5-5 of Fig. a.

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

Referring to Figs. 1 to 3 inclusive, wherein I have shown one embodiment of my invention as consisting of a jaw member and a key or wedge member 11, either or both of which may be made of spring steel, and which together grip the upper and lower surfaces of the rail base 12. The jaw member is preferably, although not necessarily, made of sheetmetal and-is in the torm ot a yoke having a channel-shaped body portion 13 which extends across the rail base. Vfhen the yoke is made of sheet metal, it is preferably provided at each end with a pair of spaced jaws 14, 1e and 15, 15,

adapted to project over and bear against the inclined upper surface of the rail base 152 at opposite sides of the rail. The jaws at one end of the yoke, for example, jaws 15, 15, are somewhat longer than the jaws at the other endof the yoke, so as to provide sufiicient clearance to permit'the pairs of jaws 1a, 14; and 15, 15 to be hooked over the opposite edges of the rail base. The lower edgesof the jaws 15, 15 are provided with shoulders 16 adapted to abut against th ad acent vertical edge of the rail base, so as to prevent any substantial accidental displacement of the yoke transversely of the rail. The length of the jaws 15, 15, will, ordinarily, depend upon the height and length of the jaws at the other end of the yoke, and also the amount of clearance between the bottom surfaceof the rail base and the upper edge of the yoke body. The body portion of the yoke is preferably substantially U-shaped in cross-section, and is tapered longitudinally in depth and width, so that it is narrower and deeper at one end than at the other.

The key is preferably made of spring metal, and is substantially U-shaped in crosssection. It is also tapered so that it increases in width and decreases in depth toward on end, thereby providing the wedge surface 1'? (see Fig. 1), which cooperates with the corresponding tapered surface 18 of the yoke to effect a wedging engagement of the key between the rail base and the yoke when the key is forced toward the shallow end 19' ofithe yoke. The sides 20, 20 of the yoke being tapered so that the channel portion decreases in width toward the end 21 of the yoke at which the key enters, and the bottom being tapered in the opposite direction, there is formed in effect a pocket-in which the key is held by the resilient gripping action of the member. The resiliency of either or both members 10 and 11, as the case may be, permits the wide portion of the key 11 to be driven through the narrow opening 21 of the yoke. As the key moves inwardly toward the wider and shallower end 19 of the yoke, the key expands so as to conform to the tapered sides of the channel.

With this construction the expansion of the key and also the contraction of the walls 20, 20 of the yoke exert spring, pressure against both members so as to effect a resilient interlocking engagement.

In order to facilitate the entrance of the wide end of the key into the narrow end 21 of the channel of the yoke, the end of the yoke is preferably flared outwardly, as indicated by the reference numeral 22. The entrance end of the key may be, and preferably is, turned slightly inward, as indicated by the numeral 23, so that the key can be easily started through the narrow end 21 of the channel 13.

In applying the anchor to a rail. the pair of jaws 15, 15 are first hooked over one edge of the rail base. The recesses defining the lower edges of these jaws are of sufficient depth to permit the yoke to be moved to the right in Fig. 1, a distance sufficient to permit the jaws let. Lt to be hooked over the other edge of the rail base. The yoke may then be moved to its-normal position as shown in Fig. 1. In this position the channel shaped body of the yoke is arranged against the vertical face of an adjacent cross-tie 24 and the key 11 is forced to its wedging position, as above described. The channel-shaped construction rigidities the yoke longitudinally, but permits slight distort-ion or flexing of the sides of the yoke laterally. The key shown in Figs. 1 to 23 inclusive is preferably relatively short and assumes its wedging position substantially at the center of the rail base. Vhen a key of this construction is used. it may be driven to its wedging position with the end of a crowbar (not shown), or other suitable implement that may be conveniently used as a ram. The wedging pressure against the upper edges of the key has a tendency to force it to conform to the contour of the channel. Vith this construction it will be seen that the key cannot move in the direc tion from which it was driven without itself contracting or effecting an' expansion of the constricted opening 21. of the channel portion of the yoke.v

In Figs. 4: and 5' I haveillustrated another embodiment of my invention in which the key designated 11 in these figures is of substantially the same length as the yoke member, thereby making it possible to ap ply the key to its wedging position without the use of a ram. The yoke and key members of this embodiment are the same as those shown in Figs. 1 to 3 inclusive. with the exception that the key 11 is somewhat longer than the key shown in the previous figures. The various parts oi the yoke, therefore, have been designated by the same reference characters as the yoke construction shown in Figs. 1 to 3 inclusive, and the parts of the key 11 corresponding to like parts of the key construction of Figs. 1, 2 and 3 have been designated by the same numerals with the exponent letter a.

.Vhile I have shown and described my improved rail anchor in connection with two specific embodiments, it will be obvious from the drawings and the foregoing de scription that other modifications in structure might be made without departure from the spiritof my invention. I therefore wish it understood that my invention contemplates all rail anchoring ,devices coming within the scope of the appended claims.
