FRED A. POOR, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE P & M COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

RAIL-ANCHOR.

Original application filed February 13, 1918, Serial No. 216,847.

Seral No. 258,407. t

To all w/om it may concern:

Be it known that I, FEED A. Poon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Impovements in Rail-Anchors, of which the following is a specification.

My invention relates to a device for preventing railroad rails from creeping longitudinally, and has for its primary Object to provide a novel and improved device of this type which will be simple in construction, inexpensive to manufacture, and easily applied to the rail, and which will act to prevent the rail from creeping in either direction; an anti-creeping device having this latter characteristic being desirable for use on single track roads where the traifc runs in opposite directions, or in other situations in which the rail tends to move sometimes in one direction and sometimes in another.

`The invention consists in the novel arrangements, constructions and combination of parts hereinafter described and claimed for carrying out the above stated objects and such other objects as may appear from the following specification.

The invention is illustrated in a preferred embodiment in the accompanying drawings, wherein Figure 1 is a view in perspective of a rail anchor constructed in accordance with my invention, applied to a railroad rail;

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

Fig. 3 is a detail plan view of a spring member employed in my preferred embodiment;

Fig. 4 is a view in elevation, looking toward the inside of the rigid or shoe member employed in connection with the spring member shown in Fig. 3;

Fig. 5 is an edge view of the spring member, showing the normal set of the spring before it is applied to its operative position on the rail;

F ig. 6 is a side view, in elevation, of a rail with my rail anchor applied in operative position thereto;

Fig. 7 is a view similar to Fig. 6, shown on a larger scale, and illustrating the spring Specification of Letters Patent.

Patented Oct. 7, 1919.

Divded and this application filed October member of my device in process of application to the rail; and

Fig. 8 is a sectional view on a reduced scale, taken on line 8-8 of F ig. 6, looking in the direction indicated by the arrows.

Like characters of reference designate like parts throughout the several figures of the drawings.

Referring to the drawings, 10 designates a railroad rail and 11, 11 two adjacent cross ties on which the rail is supported. My preferred form of rail anchor as illustrated in this figure preferably consists of a shoe or rigid member 12 and a yoke member 13, which together embrace the base flange of the rail and have an interlocking engagement with each other which maintains these members in their operative position on the rail. The shoe or rigid member 12 consists of a metal bar which engages the upper inclined surface of the base flange A of the rail base, and is formed at each end with tie engaging lugs 14:, 148 These lugs are preferably formed with shoulders which fit over the vertical edge of the base flange of the rail and are formed wiih apertures which receive spikes 15 for spiking this member to the top surface of two adjacent ties. The rigid member 12 is provided at the center with a depending flange 16 which is recessed, as indicated at 17 (Fig. 4), to receive the body portion of the yoke 13, and is formed with a boss 19 which provides a supporting shelf 18 for holding the spring yoke member 13 in its operative position, as will be hereinafter described.

The web 16 of the rigid member is also formed on each side of the recess 17 with inwardly projecting lugs 20, 21, which extend underneath the rail base and provide a rail base engaging jaw 22 which engages the base flange A of the rail at a point where the said rigid member has its interlocking engagement with the spring yoke 13. By having the spring yoke interlock with the rigid member adjacent the jaw 22, the yoke may be secured tightly on the base flange of the rail without danger of springing or distorting the relatively long bar 12.

The yoke member 13 is prefarably made of spring steel, and is formed at one end with a jaw 23 which engages the edge of the rail base opposite the jaw 22 of the rgd member and is formed with an angularly disposed hook portion 24 which is forced into a biting engagement with the upper surface of the flange B of the rail base when the anchor device is applied to the rail and is in its operative position. The spring yoke i formed at the other end with an enlargemcnt 25 which eXtends around the jaw portion o'f the rigid member 12 and interlocks thcrewith when the yoke and the rigid member are in operative position on the rail. The portion of the yoke which eXtends under the rail is preterably given a slight set or twst, as indicated in Figs. 8 and 5, so that the enlargemcnt 25 will normally stand ata slight angle with relation to the jaw 23. `When the rigid member 12 and the yoke 13 are m operative position on the rail, the body portion of the yoke adjacent the enlargement 25 extends into the recess 17 of the rigid member, the lower edge of the yoke being cut away, a indicated at 26 and Seating on the shelf 18.

hen applying the yoke 13 to its inter looked position with the shoe 12, as indicated in Figs. 1, 2, 6 and 8, the yoke is subjected to a torsional strain by twisting the same from its normal set position, as indicated in Figs. 3 and 5, to the position indicated in Figs. 1, 2, 6 and 8. This twisting operation may be accomplished by any suitable means, such, for example, as by use of the claw bar or wrench 27 which may be applied over the enlargement 25.

28 designates a boss on the wrench to engage the projecting boss 19 and provides a suitable fulcrum for the wrench when springing the yoke from its normal position, as indicated in Fig. 7 to the position shown in Fig. 6. The yoke 13, in addition to being twisted, is raised so that when in operative position, the upper end of the enlargement 25 will extend back of a lug 29 formed on the rigid member. By straining` the yoke 13 as above mentioned, the j aw end of the yoke is rocked rearwardly so that the angularly disposed lip 24 of the jaw 23 will eXert a downward pressure against the upper surface of fiange B of the rail base. The tendency which the spring yoke has when in this position to return to its normal or twisted position exerts a spring pressure against the end of the lug 29. This pressure prevents vibration of the rail from dislodging the yoke 'from its seat on the shel'f 18, or appreciably lessening its effective grip on the base flange of the rail. The spring yoke, when applied in operative position, preferably stands at substa ntially right angles to the rigid member 12 at a point opposite the jaw portion 22, so that any longitudinal movement of the rail in either direction tending to change the angular relation of these members will increase the grip of the device on the rail base.

This application is a division of my copending application, Serial No. 216,847, filed February 13, 1918.
