RAIL-ANCHOB- Specification of Letters Patent.

Application filed December 28, 1916. serial No. 139,277.

To all whom t't may concern:

Be it known that I, CHAnLEs J. Rnorrnma citizen of the United States, residing at Kings Bridge, borough of the Bronx, county of Bronx, city and State of New York, have invented a new and useful Improvement in Rail-Anchors,- of which the following is a specification.

My invention relates to rail anchors or anti-creepersfor use on railroads to prevent track rails from slipping or creeping longitudinally, and consists of a unitary structure without bolts or other fastening means tit 'my invention app of such shape as to give a reverse gripping eflect on the rail, and which engages with a tie so that the rail cannot creep without moving the tie with it.

The objects of my invention are to simplify the construction of the anchor by constructing it of a single piece of suitable material, to so construct the device that it will efiectually grip the rail in such a manner thatthe gripping will be increased by the tendency of the rail to creep, and to so shape and construct the anchor as to give it sufficient tension to lock it to the rail when placed in position.

These and further objects will more fully appear in the following specification and accompanying drawings considered together or separately.

y invention is illustrated in the accompanying drawings, in which'like parts are designated by similar reference characters in all of the figures, and in which Figure 1 is a plan view of my improved rail anchor, the rail base being shown in dotted lines;

Fig. 2 is a side elevation of the same, the rail base being shown in section;

Fig. 3 is an end view of the device, the rail base being shown in side elevation;

Fig. 4 is an elevation of a rail and tie with lied to prevent creeping of the rail in both irections; and

Fig. 5 is a plan view of ainodification.

In the drawings, 1 designates the body of the anchor which is of a general S shape. The body 1 lies under the base of the rail 2 and transversely of the same. The upper surface of the body 1 is provided with two raised portions 4: and 5. The raised portions are cut out to form right angle notches 6 and 7 respectively. The notches extend longitudinally of the rail base, and are engaged bythe base flanges 2 and 3 respec tively. The vertical face 9 of the notch 4:

the vertical face 9 of the notch 5 engages the opposite edge of the flange 3. The notches 4 and 5 are staggered relatively to each other and face in opposite directions. The outer ends of the raised portions are vertical so as to form sharp biting corners at the terminating edges of the vertical faces 9.

The body 1 is provided at one end with a projecting member or arm 10 which is curved upward and inward. The extremity of the arm 10 extends above the base flange 2 and has a sharp edge 11 engaging the upper corner of such flange. The opposite end of body 1 is curved upward and inward to form a member or arm 12 which extends over the base flange 3 and is provided with a sharp edge 13 which engages the upper corner of the flange 3. The vertical distance between sharp edge 11 on arm 10 and notch 6 is less than the thickness of the extremity of flange 2 The vertical distance between sharp edge 13 on the opposite arm 12 and notch 7 is less than the thickness of the extremity of flange 3. When driven on the rail the body 1 is cramped in an upward spring twist position under the base of the rail 2 and 3 which forces the sharp edges 11 and 13 in a gripping bite against the edges of base 2 and 3.

The notches 6 and 7 face in opposite direc; tions so that one will tend to bite into the flange when the rail moves in one direction, and the other will engage its flange when the rail tends to move in the opposite direction so as to prevent the anchor from loosen-.

ing on the rail or backing oil from its gripping position when the rail contacts from its longitudinal creeping position freeing the projecting lug or abutment 14 from the tie 15 or by vibration of trains or otherwise. The arms 10 and 12 are curved in the reverse directions giving the anchor a reverse grip to prevent the rail from creeping longitudinally, when the strain of the creeping rail forces the lug 14 against the tie 15. The notches 6 and 7 look the anchor in the opposite direction which produces four looking grips; 6 and 7 prevent the anchor from backing 0H or becoming loose and the sharp edges 11 and 13 lock the anchor against the creeping efi'ect of the rail. The arms 10 and 12 are curved in reversedldircotions and give to the device its shape.

Patented @ct. 16, 113d '3'.

The body 1 is provided with a downwardly projecting lug or abutment 1%, This lug is situated to one side of the center of the body 1, and to one side of the center line of the rail 2, and engages withthe side of the tie 15. The engaging face of lug it is slightly rounded horizontally to allow the lug to slide against tie 15 giving proper bearing surface When'arm 12 is driven to place when the anchor is applied,

The body 1, arms and 12 and lug 142 are integral, and the device is preferably formed of a cast metal such as steel which holds the anchor under tension.

will prevent arms 10 and 12 from springing, and will force body 1 in a twisting or rolling position, While I have stated that the device may be formed of a cast metal, ll wash it understood that it do not so restrict or limit myself, as the device may be made of wrought steel or other material.

The anchor shown in Fig. 5, is applied to the rail and released in connection with the form of device shown in the same manner as described in Figs. 1, 2 and 3. The same reverse grip and tie projecting abutment which gives the same leverage efi'ect, and locked to the rail by offsets or notches is practically produced the same manner as hereinafter described in Figs. 1, 2, and 3. This anchor is made of uniform thickness wrought iron or steel and forged to shape.

In the modification the rail rests on the part 1 which extends from the dotted line extending from 6 to 11 to the dotted line parallel thereto at 7. The part 1% shown in dotted lines corresponds to the lug 14 in the other figures. The part extending from the curved end above 6 to the pointll lies above the base of the rail as does the part to the left of 7. The corners of the rail base are clamped at the points marked 6, 7 and 11 as in the preceding figures,

The operation of my invention is as follows:

The device is applied to the rail by hooking the arm 10 over the top of the base flange 2". The arm 12 is then swung toward the opposite side of the rail, and arm 12 sprung on top of the base flange 3. Arm 12 is driven toward the'tie until notches 6 and '2 engage the flanges 2 and 3. The anchor now being driven to proper position, the reverse curveshape arms 10 and 12 force body 1 in a rolling or twisting position which anchor will now be firmly held to the rail, and lug 1% against tie 15 will hold the rail against movement. The more the rail has a tendency to move, the more pressure lug 14 has against tie 15, and the harder the sharp corners l1 and 13 on arms 10 and 12 will engage base 2 and 3 as shown in Fig. 3, The lug 14 being to one side of the center lineof the rail, it acts as'a lever or fulcrum and the leverage causes the sharp edges 11.

The

naaaeei and 13 to grip flanges 2 and 3 respectively. Lug 14 being in engagement with the tie, the rail cannot move forward without moving the tie. tendency to shorten the distance between the sharp edges 11 and 13 as shpwn in Fig. 1, which movement will cause arms 10 and 12 to engage base 2 and 3 in a firmer grip, which is produced by the under curve shape of arms 10 and 12 forming a tension in. body 1.

If the anchor should be applied to the rail at any point where there is a deficiency in the width of the base of the rail notch 8is provided to engage the base 3 of the rail in the same manner as does the notch 5.

When it is desired to remove the anchor, the point of a crow bar can be placed between theanchor and the base of the rail near notch 5, and the anchor forced down freeing notch 5 from rail base 3, and the anchor can then easily be removed,

(in single track roads, in stations, on sidings and in other situations where travel is in both directions on one track, it is desirable to prevent movement of the rails in both directions. To this end an anchor may be placed on the'rail at each side of a tie as shown in Fig. 4..

In accordance with the provisions of the patent statute, l have described the principle of my invention together with the apparatus which T now consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is merely illustrative, and that the invention can be carried out in other ways.

Various changes in the specific form shown and described may be made within the scope of the claims without departing from the spirit of my invention,

Having now described my invention, what I claim and desire to secure by Letters Patent is:

1. A. device of the character described, having a body, said body having an integral arm at each end thereof, said arms overhanging the upper sides of a rail base, said arms having biting portions, and means for moving the body to engage the biting portions with the rail base to prevent further relative movement of the body and rail.
