RAIL-ANCHORING DEVICE.

Specification of Letters Patent.

Yatented Jan. 23, 191'? Application filed April 15, 1915; Serial No. 91,297.

To all whom it may concern:

Be it known that I, DENNIS CiiownnY. a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented certain new and useful Improvements in Rail- Anchoring Devices; and I do hereby declare that the following is a full, clear, and exact description thereof.

The present invention relates to new and useful improvements in rail anchoring devices, more particularly of that type including a rail bed plate, and means whereby. insertion of securing spikes into the bed. plate procures a clamping action on the rail to anchor the same.

It is in general the object of the present invention to simplify the, structure and improve the elliciency of devices of this char acter, and the convenience with which such devices can be assembled.

I is more specifically an object to pro vide a rail anchoring device whereby the rail gripping means bears laterally against the body of the bed plate to thus provide a structure of maximum strength.

lVith the above and other objects and advantages in View, the invention resides more particularly in the novel combination,

- is a vertical sectional view through the anchoring device on the line 2-2 of Fig. i.

Referring now more particularly to the accompanying drawings, 5 designates a rail bed plate which is seated on the he 6 and the top face of this plate is provided with for the reception of rail spikes 10. The upper portions of the outer sides of these spikes are provided with wedge faces a and "has as the spikes are driven into the tie, a clamping action is procured at the side edges of the rail which serves to anchor'the rail to the tie a ud bed plate.

To provide a more positive anchoring means for the rail, portions of the bed plate opposite the passages 9 are-provided with vertical passages 11 extending in the direction of the rail recei 'ing recess and hav' ing their inner sides disposed inwardly of the edges of the recess whereby to underlie the edges of a rail seated in the said recess. 'llre outer sidesoi these passages are provided with intermediate outward extensions '12 for the reception of spikes 13 thus forming a general passage T-shaped in cross section. Disposed in the head portions of these passages are grip blocks 14 which have their upper portions extended inwardly to overlie the adjacent rail flange portions. and which are provided in their inner faces with recesses 15 receiving the edge portion oi the rail. "he inner faces of these recesses being toothed to have a hiting engagement with the edge portions of the rail. The spikes 13 are also provided with wedge faces e at the upper portions of their outer sides and thus as they are driven through the portiors 12 of the passages a wedge action is procured which clampingly I engages the gripping blocks with the raih the heads of these spikes overlying "the grip blocks and the upper portion of these grip blocks being laterally turned to overlie the rail base flange. heretofore stated, Where-- by the rail is firmly bound down upon the bed plate by the present structu e,' as well as etliciently anchored against horizontal movement. Each passage extension 12 is of less length than the. width. of the respective spike, and thus the spike extends into the main passage in its lateral clamping action. Alsothe width of each gripping block 1% is less than the width of the respective passage 11 whereby the block may be inserted in the passage when the rail is positioned on the bed plate, and moved in trail to engage the adjacent rail edge in its toothed recess 15.

From the foregoing it is seen that a cornparatively simple device been procured whereby the rail may he secured on the bed plate and the bed plate in turn secured on the tie and whereby the ail is eiliciently anchored against creeping movement.

headed wedge spikes extending through the passages into the tie and clampingly bearing against the blocks with the heads of said spikes engaging on-said blocks to provide the securing means of the rail and bed plate to the tie.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wis- COIlSlIl.

DENNIS E. CROWLEY.
