Application filed October 9, 1908. I Serial No. 456,888.

To all wkomtt may concern:

Be it known that I, MARCUS S. CLARKE, a citizen of the United States, and resident of Houston, Harris county, Texas, have invented certain new and useful Improvements in Combined TiePlat'es and Rail-" Anticreepers, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereoi;

My invention relates to a combined tie plate and rail anti-creeper, the object of my invention being to construct a simple, inexpensive device which is apphed to railway ties beneath the railway rails, and which dc.

vice is provided with means which very firmly grip one of the base flanges of the rails to prevent undue lengthwise movement or creeping of said rail.

Tothe above purposes, my invention consists in certain novel features of construc-" tion and'arraugement of parts, which will be hereinafter more fully'setforth, pointed out in the claims, a'ndillustrated in 'the ac-- companying drawings, in which 1 Figure 1 is a perspective view oia device of my improved construction positioned for use upon a tie, and beneath a track. rail;

Fig.2 is a cross section taken approximately on the line 2-2of Fig.1; Fig. 3 is a'horizontal section taken on the line ii- 3 f Fig. 2; Fig. 4 is a section similar to Fig. 2, and showing a modified form of the tieplate and rail anti-creeper. Fig. 5 is'a detailed section showing a modified form of the -key or rail gripping member.

Referring by numerals to the accompany- 1 ing drawings: to plate,

1 designates the body of the w ich occupies a position beneath t e track rail and on top of the railway tie, and said plate is preferably provided on itsunder side with a series of-sharfr-aibs v2,

tie whenithe plates and rail are spiked to said tie.

Formed through v 'the plate 1- are apertures 3 adapted to receive spikes 4, the heads of which engage over the base flanges of the track rail to rigidly fix the same in position. Formed integral with the top ofthe plate '1, and at a point midway between the side edges thereof, ""e lugs 5, which are formed by ressingthe metal of the plate upward;' or, lfthe plate be cast, said lugs are formed integral with the body of the plate; and these lugs are so spaced apart as to readily receive the base flange of the'rail. Formed through the edge of one lug and through the body of the plate 1, immediately adjacent the edge of said lug, is an aperture 6.

After the, tie plate has been properly ositioned 0n the tie and the rail is spikes in positlon on said tie plate, a wedge shaped the binding edge 8, may be provided with a vertically disposed ii-shaped groove 9, thus forming a pair of sharp binding edges the lug in which the aperture 6 is formed when the key is driven into position; and

this arrangement tends to firmly hold said key against'withdrawal from the aperture 6.;

In ig. 4 have shown a modified form of the device-wherein the plate 1 is perfectly flat, without the ribs 2 and lugs 5; and

rigidly fixed in any suitable manner to one side of this fornrof plate is a metal brace '10, which engages against one side of the track rail, and the key 7 passes through an apertnreidl formed through the plate 1,

opposite the brace l0.

In Fig. 51 have shown the key or gripping member, as bein provided on one edge with "a series of teeth, and when said key on this side of said key, which pair of edges I tend to embed themselves'fin the edge of is driven into the tie, these teeth out into the edge of the base flange of the track rail,

thus forming a pair of shoulders at the sides of thekey or gripping member, which ct- :Eectnally prevents the rail from creeping 'movement in either direction.

The key 7 is made wedgeshaped or tapers graduallyfrom top to bottom, in order that when driven into the tie it will exert a wedging action betweenthe lug o and the edgeof the base flange of the rail, and. will therefore effectually engage andlock the rail to thetie plate. A tie late and rail anti-creeper of my 'improve construction is very simple, in-

j formed on the top v of which lugs engage the edges of the base flanges of the rail gradually to bottom and one expensive, is adapted for all forms of track rails, and provides simple means for maintenance of rails in proper position on the ties; and very effectually prevents said rails from longitudinal movement or creeping.

1. A device of the class describedcomprising a plate. adapted to be positioned on a tie'beneath a railway rail, ribs integral.

with the underside of said plate, lugs of the -plate,the edges there being an aperture formed through the plate at theend of one of the lugs, through said aperture, which: key tapers throughout. its length from top of the sides of which key is provided with verticallydisposed sharp teeth.

2. A combined tie plate and rail anti- I creeper, coinprisiiig a base plate formed of a single piece of metal, an integral rib formed on theunder side of said base plate,

an outer and inner lug-formed on the top of thefplate, which lugs are formed by being struck and pressed upward from the body of the plate, the interior edge of the outer lug being adapted to engage the outer t edge of the base flange of the rail tor hunting the outer movement of the rail, the inner one of said lugs be ng provided with a recess formed in its top wall, coinciding with 'driven through said recess a key adapted to be drivenone of said lugs cess formed in its top wall, coniciding with I the opening formed intthe plate from which the opening formed in the plate from which said lug is struck, and a key adapted to be and the opening in-the plate formed beneath it, said hey havingits opposing edges gradually tapered from the head to the point.

3. A combined tie plate and rail anticreeper, comprising a base plate formed of a single piece of metal, an integral rib formed on the under sideo'f said base plate, an outer and inner lug formed on the top of the plate, which lugs are formed by being struck and pressed upward from the body of the plate, the

interior edge of the outer lug being adapted to engage the outer edge .of the base flange of the rail for limiting the outer. movement of the rail, the inner being provided with a resaid lugis struck, and akey adapted to be driven through said recess andthe opening in the plate formed beneath it, the opposing
