Application fi1edAug ust 27, 1915. Serial N 0. 47,561.

To all whom it may concern:

Be 1t known that we, CHARLES E. Dory,

' a citizen of the United States, and a resident of New York, county of Bronx, State of New York, and JOHN E. LATHROP, a citizen of the United States, and a resident of the city of Yonkers, county of Westchester, and State of New York, have invented certain new and useful Improvements in Combined Tie-Plates and Antic'reepers, of which the following is a specification.

Our invention relates to an improved tie plate and anti-creeper for use in railroad construction.

One of the objects of our invention is to so construct and combine a tie-plate and anti-creeper that the anti-creeper will bite into the edge of the rail base on the side opposite the gage side of the rail.

Another object of the invention is to so construct a tie-plate and anti-creeper that the wave motion of the rail will not be interfered with, the creeper being so positioned that it may rise and fall with the rail when the load passes thereover.

Another object is to so construct the anti-creeper that it will not become loose from the rail by reason of the changes of temperature.

Other objects will appear from the following specification and claims.

Referring to the drawing which forms a part of the specification; Figure 1 is a sectional view of the rail, tie-plate, tie and anti-creeper device assembled in position for work. Fig. 2 is a'plan view, partlywb'roken away, of the tie-plate and anti-creeper. in

assembled position, the anti-creeper being shown partly in section. Fig. 3 1s a perspec-' tive view of one form of anti-creeper device..

Fig. 4 is a perspective view of another form of anti-creeper device. Fig. 5 is a sectional View, partly broken away, similar to Fig. 1, showing a modified form of anti-creeper device in position. Fig. 6 is a sectional View on line 6-6 of Fig. 1.

In the drawing, like reference characters refer to like parts.

A is a cross-tie, B the tie-plate, C the rail and D the spikes shown in the usual position. A depression 10, rectangular in shape, is rolled on the face of the tie-plate next to and adjoining the shoulder 11, which shoulder is adjacent to the outside base.

-of the base 12 of the rail. The lower portion-of the depression at 13 extends a short distance under the outside edge 14: of the base of the rail. A depression is also rolled, as at 15, in the shoulder 11,'the total depth of the depression being equal to the height of the shoulder plus the depth of the depression rolled in the face of the tie-plate. A piece of case hardened steel defined'in the art as an anti-creeper 16, is so shaped that it fits at its ends and bottom in the depression which has been formed in the tie-plate and shoulder. The depression measured transversely is greater than the width of the lower flange 18 of the anti-creeper so that a space is provided underneath-the rail for the play of the anti-creeper.

The anti-creeper is made of an integral piece of case hardened steel and is provided with'upper and lower jaws or flanges 17 and 18 extending from the same side of the vertical integral web 19. The inner side of the vertical integral web is provided with a series of teeth 20 cut at an acute angle with the edge of the rail, the teeth extending-opposite to the line of direction of traffic; in other words, the line of direction of creep of the rail.

In Figs. 4 and 5, we have shown a modilied form of anti-creeper in which teeth 21 formed at an acute angle with thehorizontal are also cut in the lower face of the upper flange 17. In all forms the lower flange 18 is less in width than the upper flange and its upper face is below, as at 26, the under surface of the rail, so that the rail will rest on the tie-plate and not on the anticreeper device, as clearly shown in the drawmg.

The anti-creeper device is fitted into the.

depression which is rolled in the shoulder and face of the tie-plate with the narrower flange resting on the bottom of the depression. The rail is then placed upon the tieplate and the edge of the base of the rail, which is opposite the gage side of the rail, is inserted between the flanges of the anticreeper device. The tie-plates with the previously inserted anti-creeper are then hammered into place so that the teeth of the anti-creeper device are embedded in the rail The sides of the teeth which are at an acute angle extend in the line of direction of traffic. The spike holes 30 preferably 3;" square are previously formed in the tie- Patented Sept. 26, 1916.

plate at points on opposite sides of the rail base and the spikes l) are driven in place as usual.

The anti-creeper extends, as shown, over the top of the base of the rail and the upper surface of the creeper extends a short distance as at 25 above the upper surface of the shoulder in the tie-plate.

From the above description it Will be seen that as the action on the rail due to the passing load is on the gage side of the rail, the natural tendency is for the rail to engage tightly into the teeth of the creeper and inasmucl'i as the creeper is prevented from moving in a horizontal direction, the rail is prevented also from having a horizontal, movement, or in other Words, from creeping. It ill also be seen thatby the use of our in- -1 vention the Wave motion of the rail is not impeded in any Way, as the creeper isfr'ee; to move up and downwith the rail.

Having now described our inventiom vhatf We claim as new and desire to secure by Let-f; ters Patent is:

1. In combination, a tie plate having ahole therein, a rail resting on the tie plate the base of the rail covering a POItlOIl'Of the hole in the tie plate, a U shaped anti-' creeper device fitting closely in the hole of the tie-plate, theupper leg only of the U-' shaped anti-creeper device having teeth formed in its under-surface, said teeth engaging With the upper surface of the base of the rail.

2. In combination with a rail of a fixed tie plate havlng a hole thereln, said holebeing provided with substantlally vertical Walls, a U shaped anti-creeper device fitting closely in said hole and embracing the edge of the base of the rail, said anti-creeper device being fitted to move bodily in a vertical direction only with the n'loveinent of the base of the rail.

3. In combination with a rail, a tie plate having a hole therein, a U shaped anticreeper device fitted in the hole in the tie plate and emln'acing the base of the rail, a lip projecting from the top surface of the tie plate adjacent the hole therein, one face of the lip being contiguous with the outer Wall of the hole in the tie plate, the base of the U shaped anti-creeper device engaging the said face of the lip on the tie plate.

lyln combination, a tie plate having a hole therein, arail resting on the tie plate, the base otthe rail opposite to the gage side only of the rail covering a portion of the hole in the tie plate, a U shaped anti-creeper device fitting, closely in the hole of the tie plate, the upper leg of the U shaped anticreeper device having teeth formed in its under-surfa the base of the rail opposite to the gage side of the rail.

In Witness whereof we have hereunto set our hands at the borough of Bronx, city and State of New York, this 12th day of August, 1915.
