Original applcation led Hay 17, 1922, Serial No. 561,603. Divided and this application filed March 14, 1923.y Serial No. 624,930.

To all 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 anchoring devices adapted to resist the tendency of railroad rails to creep longitudinally.

One of the objects of the invention is to provide an improved one-piece rail anchor which may be easily applied to or removed from the ange of a rail without danger of subjecting the anchor to excessive strains, and which will be maintained in its applied position b spring pressure of the anchor.

A s ci c object ofthe inventionv is the provis1on of a rail anchor having a -jaw adapted to be driven into tight engagement with one ange of the rail base, and having a 4body which extends under the rail base and engages the other edge thereof, the body belng provided with a relatively flexible portion .adapted to flex downwardly during the application of the anchor to the rail so as to relieve the jaw portion of the anchor of excessive strains.

A more specic object of the invention is the provision of a rail anchor of the above character that can be conveniently manufactured of sheet metal so as to provide one or more relatively rigid jaw portions adapted to engage one edge of a rail base, and a somewhat resilient portion adapted to extend under the rail base and bear with resilient pressure against the other edge of the rail base.

A further ,object of the invention is the 4U provision of an anchor device having a relatively rigid jaw and a spring tongue for engaging op osite edges of a rail, and to so form the anc or that the engagement'of this jaw and tongue with the rail will be confined 125 to portions adjacent opposite edges of the rail base.

The invention further consists in such other new and improved constructions relatscribed and claimed for carrying out the above stated objects, and such other objects as will appear from the following description.

The invention is illustrated in certain preferred embodiments in the accompanying drawing, wherein like characters of reference designate corresponding parts throughout the several figures thereof, and where- Fig. 1 is a front View in elevation of a rail anchor device constructed in accordance with my invention, shown applied to the base ,flange of a rail, said base flange of the rail being shown in cross-section;

Fig. 2 is a plan view of the structure shown in Fig. 1.

Fig. 3 is a front view, partly in elevation and partly in section, of a modified form of .rail anchor constructed in accordance with my invention; and

Fig. 4 is a view in perspective of the modified construction shown in Fig. 3, the base gauge of the rail being omitted in this re. glieferring first to Figs. 1 and 2 of the drawing: 10 designates the base portion of a railway rail and 11 one of the cross-ties on which the rail is supported.

My improved anchor, as shown in Figs. 1 and 2 of the drawing is made of sheet metal, preferably spring steel, and is formed -at one end with a hook-shaped jaw portion 12 which engages the vertical and both the upper and lower surfaces of the rail base at one side of the rail, and at the other end with an upstanding lug Aor shoulder 13 adapted to engage the vertical surface of the rail base at the other side of the rail. The jaw Iportion 12 is provided with a lip 14 which projects over and bears against the upper inclined surface of the rail base, the lower edge 15 of the lip being cut at an angle corresponding to the inclination of the upper surface of the base flange of the rail. The lower edge of the lip 14 is provided with a recess 16 so as to prevent en agement of the lip with the upper corner ol the rail base, thereby insuring against the possibility p 10 cessive distortion.

5 assumed by/the anchor rail base,

5 16, the jaw may be made relatively rigid yet possessed of suicient resiliency to permit its application to rails made within the allowable variation in thickness of their base Hang-es withoutl sub'ecting7 the jaw to ex- 'l`he vertical edge 17 of the jaw preferably, though not necessarily, engages the vertical surface of the rail base. i In order vto minimize the flexing of the jaw portion during the application of the anchor to a rail, and to relieve it of the severe strains incident to such iexing, I preferably make the shoulder 13 relatively short andM decrease the width of the body 18 of thev body adjacent the shoulder 13 will be more flexible than the portion of the body adjacent thejaw end ofthe anchor. With will flex on a horizontal axis when the jaw 12 is driven to its rail-gripping position. As soon as the shoulder 13 clears the either edge of the rail-base,. it will snap, into the position shown in Fig. 1. l

The upper edge of the body 18 is preferably recessed, as indicated at 19,2.soas to avoid improper. engagement of the anchor with the rail in the event that the bottom surface'f the rail is formed with rough or uneven Ysurface at the point where the anchor is applied- The relatively wide portion of the body adjacent the jaw end 12 provides a suitable tie abutting surface.

.In applying the anchor to a rail, the jaw portion is hooked over one edge of the rail 'base and the anchor then driven in the direction .of its length across the rail until the shoulder 13 snaps over the opposite edge of the rail base. `In the various positions during the application to the Vrail until the shoulder 13 snaps over the opposite edgeof the rail base, the narrowest portion of the body, g'eater flexibilityv than the jaw portion of t e anchor, will ilex downwardly and thereby minimize the flexing strain on the jaw portion of the anchor.

`In Fi 3 and 4, I have shown a modified form o the invention made from a sheet metal blank cut and bent to the form shown =in Fig..4. This embodiment of the invention consists of a flat body portion 20` adapted to extend across the rail base, and is formed at one end with two relativel rigid

upstanding jaw portions

21, 22, having recees 23 which receive one edge of the rail base. The'jaw

members

21 and 22 are adapted to be driven to a tight gripping contact with the upper and lower surfaces of the and the body portion 20 is adapted toward the shoulder 13, so that the portion this construction, the body portion being of madera to flmction as a spring tongue to maintain es the device in its a plied position. The body portion is prefera ly bent upwardly toward the rail and bears against lthe under surface of the rail near one edge thereof, thereby providin a space between the bottom sul face of t e rail base and the body portion of the anchor which will prevent rough or uneven portions of the rail base interferiing with the proper application of the an chor. The body portion decreases in width towards one end, so as-to make it more ilexible at this end, and is provided with an upstanding lip 24 whichl by reason of the resiliency of the body of the anchor snaps over the opposite edge of the rail base when the anchor is driven home. When the anchor is in its Iapplied position, one of the

upstanding jaw portions

21 or 22, as the case may be, will be in position to bear against an 'adjacent cross-tie. By decreasing the width of the body ortion 20, the end of the anchor adjacent te lip 24 is held out of engagement with the tie,

thereby permitting the anchor to assume .a slight diagonal .posltion across the rail base, if such position be necessary to take between the lip 24 and the

vertical edges

25, 25 of the

jaw portions

21, 22.
