RAIL ANCHOR Filed Aug. 6, 192a gwwnkw Claudeflfiirai Patented Sept 17, 1929 UNITED STATES CLAUDE A. STRAIT, F panama, mmnnaema RAIL Anqgoa I Application filed August 6, 192's, seen as 237,523,

The present invention relates to a rail anchor for anchoring rails against creeping. In case where most of the traliic on a railroad is in one direction or where the heavy traffic is in one direction with the empty cars returning in the opposite direction the rails have a tendency to creep along the ties. Various devices have been employed to correct or arrest this creeping of the rails but most of these devices are either so complicated as to be expensive and difficult to install or else have a tendency to loosen and thus destroy their usefulness.

An object of the present invention is to 5 make a strong, simple, and effective rail anchor which may easily be installed and which will require a minimum of up-keep and repairs.

In order to attain this object there is pro- 2 vided, in accordance with one feature of the invention, a pair of jaw members adapted to engage the sides of the base portion of a rail, one of said members being adapted to lockingly engage the head of said bolt. These members are positioned to engage a side of a railroad tie to anchor the rail against creeping. These and other features of the invention will be more fully brought out in the following description and the accompanying 3o drawings wherein:

Figure 1, is a View in top plan of a portion of a. rail mounted upon a portion of a tie with the anchor device in position on the base of the rail.

Figure 2, is a vertical sectional view of the device shown in Figure 1 showing the rail in section and the tie and anchoring member in elevation.

Figure 3, is avertical sectional View through the anchoring member and the base of the rail.

Figure 1, is a view in perspective of one of the jaw members that engage the base of the rail.

Figure 5, is a view also in perspective, of the other aw member.

Figure 6, is a sectional view on the line 6-6 of Figure 3.

Referring to the drawings in detail, the anchor comprises a jaw member 1 having a ce s hereinto ngage the base flang 3 f a railway rail i- Th s' jaw em r pm:

to the jaw member The u seat h head of the bolttfi is provided with four grooves 12 one adjacent to each edge of the head of the bolt 6 to register with the lockingpin groove 10 of the anchor member .7 for each degrees rotation of the bolt 6.

In using the device a jaw member 7 is slipped over the shank of the bolt 6 and the bolt is threaded into the opening 5 in the jaw member 1. The jaws are separated to a distance greater than the width of the baseflange of the rail and are then slipped beneath the base-flange of the rail and the device is moved closely adjacent a side of the tie toward the direction from which the heaviest traflic comes. The bolt 6 is then turned by a means of a suitable wrench to draw the jaws 1 and 7 together, firmly gripping the base-flange of the rail 4 between them.

When drawn to the point of maximum pressure the bolt head is turned so that one of the grooves 12 in the bolt-head is in register with the locking-pingroove 10 in the jaw member 7. A locking-pin which is preferably of a size to have a close driving fit in the opening provided by the

grooves

10 and 12 is then driven into this opening to firmly lock the bolt 6 against rotation relative to the jaw member 7 and the rail base. The other jaw member 1 is of course held against rotation by its engagement with the base-flange of the rail so that no displacement of any of the parts is possible without distorting some of the members or removing the locking-pin 11.

The device is simple and effective in operation, easy to install and as it comprises but four operative parts including the lockingpin the cost of the device is extremely low. The device may be shipped completely assembled except for the locking-pin so that there are no loose nuts or parts to be lost.

I claim:

A rail anchor, comprising a bolt having a groove on the inner face of the head thereof, a jaw member having a rail gripping groove at the top on the inner side thereof and having a portion thereof extending below the bolt when in an operative position to engage a tie, and having a smaller groove in the outer face thereof to coincide with the groove in the bolt head; a second jaw member having a groove therein to lie above the bolt on the inner side of said jaw member when said jaw member is in an operative position and having an extension beneath the bolt when the jaw member is in an operative'position to engage a tie, and having a threaded opening therein to threadedly receive the bolt to draw the jaw members together to grip a rail flange ,therebetween, and a pin adaptedto be inserted in the opening formed by the coinciding grooves on the inner side of the head in the outer side of the first jaw members to prevent rotation of the bolt with respect to the jaw members.

p In testimony whereof I affix my signature.
