Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed February 8, 1918. Serial No. 216,011.

To all whom it may concern Be it known that I, FREDERICK L. H. SIMS, of the city of Toronto, i 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 for attachment to the bases of railway rails to engage the ties to prevent creeping of the rails and my object is to produce a device of this kind which will be cheap, eflicient.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which Figure 1 is a plan view showing my invention as applied to a rail, the rail being shown in dotted lines, and the movable abutment member shown in place;

Fig. 2 a vertical section showing the device in place on a rail;

Fig. 3 a similar view to Fig. 2, the movable abutment member being omitted;

Fig. 4: a perspective view of the abutment member;

Fig. 5 a plan view showing the method of blanking out the abutment members;

Fig. 6 a plan view showing the method of blanking out the split. wedge keys;

Figs. 7 and 8 perspective details of the wedge key formed by the method illustrated in Fig. 6;

Fig. 9 a side elevation of the device in position showing a movable abutment member in place; and

Fig. 10 a similar view showing a modification of the movable abutment member.

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

1 is an abutment member, which is blanked out as shown in Fig. 5 and thus formed without waste. The blanks, it will be noted, are formed with projections 2, 3 and 4, which are subsequently bent as shown particularly in Fig. 4 to form a lip 5 adapt ed to fit over one edge of the rail base and two abutment flanges 6 which fit under the rail base as shown particularly in Fig. 1. These abutment flanges not only serve to engage the sides of the ties to anchor the rail, but also by engaging the under side of simple and the rail base to prevent the tipping of the abutment member under the clamping action of the securing bolt.

This bolt is formed at one end with one or more hooks 7, which hooks are adapted to engage the edge of the rail base as shown particularly in Figs. 2. and 3. At the other end of the stem of the bolt is formed a slot 8 adapted for the passage of a wedge key 9. When this wedge key is driven tight as shown in Fig. 3, the abutment member will be tightly clamped to the rail. Such wedge keys show no tendency to slip and the device will remain securely clamped in position. If split wedge keys are used, the security may be increased by spreading the parts,

1 It will be noted that the depth of the slot is at an angle to a vertical plane through the axis of the bolt so that the wedge key is driven diagonally. This not only facilitates driving, but also prevents direct contact of the end of the key with either the tie or the ground, as would be the case if the keys lie either horizontal or vertical. The wedge also extends above the level of the under surface of the rail base so that the strain of the wedge key clamps the lip 5 against the edge of the rail base instead of tending to bend the lip backward as would be the case if the contact of the wedge key with the abutment member was entirely below the level of the rail base.

The wedge keys are preferably cut as shown in Fig. 6 and the out parts bent as shown in Figs. 7 and 8. From the method of blanking out, it follows that the connection between the parts of the key is at the narrow end of the key in one case and at the broad end in the other. With a key such as shown in Fig. 8, the ends may be spread in the ordinary manner, but in the case of the key such as shown in Fig. 7 a tool must be introduced between the two parts to spread and deform the same.

The object in providing two hooks on the end of the bolt is to permit of the use with the device of a movable abutment member 10, (see Figs. 1, 2 and 9.) The books 7 are therefore formed at difierent distances from the slotted end of the bolt and face in different directions, so that either one may be engaged with the edge of a rail base. If a movable abutment member is to employed, the hook which is farther from the i in its other end through which the end of the bolt passes. e slot permits adjustmentSo that the device is readily adapted to di fiere'nces which may e 'xist in the spacing of the ties. When the movable abutment member is in use, the rail is anchored against creeping in either di'rection.

A modification is shown in Fig. 10, the

abutment member being formed with a pointed hook 13 w'hich may be driven into a tie as shown. Theother end of the memi vber isformed With an eye 14 through which 7 the slotted end of the bolt passes.

The device, it will be seenyis very simple as even in its most elaborated form there:

are only four parts, which in the simpler form are reduced to three. The device is easily formed from sheet metal and is light in weight ascompared with the ordinary types of malleable cast iron anchors. The

slot-ted bolt with which the wedge key is used provides means itor securing the abutment in place whichfwill not loosen up; thus making the device much more. reliable than any form of rail anchor with which nuts and bolts are employed. 7

What I claim as my invention is; g V '1. In a device of the class described, the combination of an attaching member comprising a bolt having two hooks formed at one end facing in different directions and located at different distances from the other end of the bolt, either hook being adapted to engage one edge of a rail base, and a stem adapted to pass under the rail base; an abutment member having a hole therein for the passage of the said stem provided with an abutment flange and a lip adapted to fit over the opposite edge of the rail base; means engaging the stem and the abutment member to clamp the latter and the hook securely against the edges of the rail base; and a movable abutment member adapted to be clamped between said means and the abutment member aforesaid when the hook farthest from the end of the stem engaged by saidmeans is engaged with the edge of the rail base. 7 v v Q 2. In a device of the class described,,an abutment member adapted to be clamped to one edge of a rail base, in combination with a bolt adapted to eXtendunder the rail base, the said bolt comprising a bar bent on itself to form a'slot adJacent the abutment, the

double part extendingthrough a hole in the abutment, the bolt also having hook formed at the other end to engage the other edge of the rail base,

ed to be driven into said slot to engage the clamp the latter in place. r

,v 3. In a device of the class described, an abutment member adapted to be clamped to one edge of a rail base in combination outer surface of the abutment member towith a bolt having two hooks formed at one end adapted to engage the other edge of the rail base and a slot formed through its other end, said hooks being -located at different distances from said other end of the bolt and facing ih diii'erent directions; a wedge key adapted to be drawn into said slot to engagev the outer surface of the abutment member to clamp and a wedge key adaptthe latterv in place; and a moV- able abutmentmember adapted to be clamped between the we ge key and the abutment member aforesaid when the hook farthest, from the slotte engaged with the edge of the rail base.
