RAIL-ANCHOR.

Specification of Letters Patent.

Application filed. September 5, 1919, Serial No. 321,881.;

and useful Improvements in Rail-Anchors,

of which the following is a specification.

My invention relates to rail anchors, and

has for its object to provide a new and improved rail anchor which will readily yield to compensate for the expansion or contraction of the rail to which it is applied, which will gripthe rail with a spring pressure so as to resist the tendency which the vibration of the rail,or other causes, has

to loosening its efi'ective grip on the rail,

and which will increase its grip on the rail during any longitudinal creeping of the rail.

'My invention contemplates a device made up of a plurality of parts, certain parts of which are made of cast metal and certain other parts though it will beobvious from the following description that modifications in structure might be made without departing from my invention.

The various parts of my preferred form of anchor are of such construction that they may be readily constructed, assembled and permanently secured together at a minimum cost of labor and material. Then the parts are assembled they provide, in effect, a one piece anchor which is less expensive to 'manufacture than a similar device made enand at the same time tirely of spring metal, possess the meritorious features of a device made entirely of spring metal.

The invention isillustrated in the accompanying drawings, wherein:

Figure 1 is a plan invention, illustrating the manner in which it is applied to the rail; v

Patented Oct. 1920. i

vice shown in Figs. 5', 6 and 7; s

Like characters of reference designate like partsthroughout the several figures of'the drawings.

Referring first to Figs. 1 to 4:: inclusive of the drawings: 10 designates a railroad rail and 11 one of the cross-ties on which the rail is supported: The form of the invention shownin these fi res consists, preferably, ofa casting. mem er 12 and. a spring metal member 13 which together embrace the base flange of the rail. The casting member is'formed with a depending flange 14 adapted toibear against one of the vertical faces of the tie 11, and is formed with an integral, relatively narrow, aw 15 which fits over one edge of" the base flange. of the.

rail. The casting member, preferably pros jects beyond the jaw, as indicated at 16 (Fig. 4:), and is formed at itsouter end with; a curved recess 17.; The spring element'13 is preferably round in cross-section, andis formed at onevend with a hook or-jaw portion 18-which fits over the opposite edge The-other endofthe spring 1 is bent as indicated at 19,. so as to fit the.

of the rail base.

curved recess 17, and is rigidly-secured in a bore 20 formed in the casting by any suitable means, such for example as-by a pin 21, as shown in Fig. 2. It will be obvious that the sprlng element 13 if desired might be secured in the casting by supporting it in the castin mold and pouring the molten metal aroun it, instead of securing it in the bore20, as above described.

= When the casting and'spring

elements

12, 13, are secured together, the bent portion 19 of the spring substantially fits the curved seat provided by the recess 17in the casting,

and the jaw end 18 of the spring extends at an angle with relation to the face 22 ofthejaw15.' I

When applyingtheanchor to the rail,

the jaw 15 of the casting 12' is applied. over one edge of-the'basefiange and the tie abutting portion is so positioned with relation 11 that the toe portion 23 thereof engages one of the vertical faces of the tie. When the anchor is thus far applied, the element 13 assumes a diagonal posi r tion under the rail base, substantially as in-i to the, tie

spring dicated in dotted lines at A, (Fig. 1). The jaw end 18 of the spring element may then be forced in a direction away from the tie to the position shown at B in Fig. 1, in which position the hook portion thereof -will clear the vertical edge of the rail.

Upon releasing the spring element IltfWlll return to its normaloperative position, as shown at (3 in Fig. 1. When theanchor is in its operative position, the spring element 13 takes a shackle hold on the rail, and exertssuflicient pressure against the edge of V the rail base to resist the tendency of the vibration of the rail, or other causes, to loosen the effective grip of the device on the rail. Any longitudinal movement of the rail toward the tie increases the pressure of the tie abutting portion 14- against the tie and causes the casting element 12 to rock in the directionindicated by the arrow in Fig. 1. The tie abutting foot 14: is preferably formed with a curved surface 24L tov facilitate this operation. The rocking action of the casting tends to shorten the distance between the

jaws

15, 18, so as to increase the grip of the device on the rail. Any longitudinal movement of the rail toward the tie has a tendency to move the jaw end 18 of the spring element 13 toward the tie, and in this way increases the grip of the device on'the rail irrespective of any rocking movement of the casting member 12.-- During the clear the vertical edges of the rail.

rocking movement of the casting it will be seen that there is a combination of both in the space 29 between said flanges 27, 28'

by a rivet 34. The spring yoke is also formed with

reverse curves

35, 35, adapted to normally seat against the curved portions 30, 3O ofthe flanges, so that the opposite ends of the spring yoke assume the positions shown at D, D, before the

jaws

32, 33 are sprung into engagement with the edges of the rail base. The

jaws

32, 33 may be applied over opposite edges of the base flange of the rail by springing the ends of the yoke 31' in opposite directions until the

edges

36, 37. ofthe

jaws

32, 33, respectively The jaws being released in this position will as- V sume their operative positions E, E, by

spring action. When the spring yoke is in its operative position, the straight portion 38 of the yoke extends at an angle with remember being and described except in so far as specific limitations may appear in the appended claims.
