UNHTED STATES ALBERT E. SHIRLEY, OF TORONTO, ONTARIO, CANADA.

RAIL ANCHOR.

Application filed September 22, 1922, Serial N'o. 589,913.

1 '0 all 11:71am it may concern:

Be it known that I, ALBERT E. SHIRLEY, of the city of Toronto, in the county of York, Province of Ontario, Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specification.

This invention relates to devices used to prevent creeping of railway rails, and it is my object to devise a construction for this purpose which will be of few parts and which will therefore be simple to construct and to place in position; and which at the same time will exert a firm grip on the rail to prevent its creeping.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which- Fig. l is a side elevation showing my rail anchor in position;

Fig. 2 a plan view of the same; and

Fig. 3 an end view of the same.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

My rail anchor comprises only two essential parts, the reach bar 1 and the key 2, while a third part, the key 3, may also be used if found desirable.

The reach bar 1, in my preferred form, which it will be noted is of substantial width relative to its length, is made from Wrought iron or steel and has a portion at one end thereof bent upwardly to form a hook 4t for engagement with the rail base. The other end of the reach bar 1 is doubled back upon itself at 5 for a short distance and then upwardly inclined at 6 to form a recess 7 for receiving the other side of the rail base.

it one side of the bar 1 at the end adjacent the hook 4 is formed the downward l v projecting abutment member 8 which engages the side of the tie.

Partly in the portion 5 and partly in the upwardly inclined portion 6 and through the main part of the bar 1 is formed a substantially round hole 9 to receive the kev 2. This key 2, it will be noted, is of conical form, which is in marked contrast Renewed October 27, 1924.

to previous constructions in which the keys 2: re of rectangular form in cross section.

The device is used as follows: The reach bar 1 is pushed under the rail base and the edge of the rail base engaged 'in the recess 7. The reach bar is then drawn back until the hook 4 is engaged with the other edge of the rail base. The key 2 is then driven into position as shown. The key, it will be noted, only engages the edge of the rail base and the opposite side of the hole 9. The key 2 will be driven in until a dinge is formed in the edge of the rail ase. The forming of this dinge is very important, as through it, any creeping of the rail relative to the rail anchor is prevented. v

I may, however, if desired, as an additional protection, form a slot 10 in the key 2 and drive a divided taper key 3 into said slot, the ends of the key 3 which project. through the slot being spread.

The reach bar, however, in some cases may be made as a malleable casting and good results obtained.

The key 2 and hole 9 may be of other forms than that shown and described, the important feature being that the key have a comparatively narrow bearing surface against the edge of the rail base and a comparatively wide bearing surface against the back of the hole.

From the construction described it will be seen that I have devised a construc tion which will satisfactorily attain the objects of my invention as set forth in the preamble of this specification.

hat I claim as my invention is 1. In a rail anchor, the combination of an integral reach bar having a hook formed at one end adapted-to enga e one edge of the base of a rail, a recess a its other end in which the other edge of the base of the rail is adapted to be received, said recessed portion having a hole therethrough and a downwardly directed abutment member, and a conical key adapted to be received in said hole and engage the edge of the rail base.

In a rail anchor, the combination of an integral reach bar formed of wrought metal having one end thereof bent up to form a hook adapted to engage one edge of the base of a rail and its other end bent back on itself for a short distance and then inclined upwardly to 'form a recess for re- 'adjacent the hook, a hole being formed through said bent back portion; and a key adapted to be received in said hole and engage the edge of the rail in the recess. 10'

Signed at Toronto, Canada, this 16th day of September, 1922.
