Be it knmvn that 1, Boone M. Sm'rn, a citizen of the United States, residii'igat New York city, in the county of New York and State of New York. have invented certain new and useful improvements in Anticrcepers, of which the following; is a specification.

My invention relates to devices for checking the tendency of railroad rails to creep longitudinally in the direction of travel over the track such devices being con'i'tnonly called anti-ereepers, rail stays or anchors. I

this of the objects of the illVtEtll'lOll lo provide a device of this sort which will not cause the tie against which it abuts to cant or turn. in the road bed. Most of the rail anchors now in use are ()l)j(illll11tll')l6 to'a greater or less extent because they operate in this manner. If the tie is thus canted or turned it is necessarily loosened in the ballast and it a tie plate is used the turning of the tie brings the sharp edge of the tie plate against the bottom oil the rail. Both these results are objectionable for reasons well understood by railroad men.

Afurther object is to provide a simple and effective device which will serve the double purpose of tie plate and anti-creepcr.

A further object is to provide a. device of this character which can bevcry cheaply manufactured; for example, from rolled sleek.

A further object is to provide an anti-- creeper which is bolted to the rail, so that its hold thereon is positive, but which is also constructed so that it has a lritttional grip on the base of the rail that relieves the belt of some of the stress to which it would be otherwise subjected. lly thh means the .--'i'ieariao of the bolt or the loosening ol its t'ollllt't'iltm with the rail and anli-ertwper is lllilllllllZttl.

The invention is illustrated, in a prel m-rm! elnbodinient in the armnipanyin g' drawing. '\vl1erein Figure 1 is a plan view of the device shownas applied to a railroad rail: hie. 52. a side elevation; Fin. 3. a sectional view taken on line 3 3 of Fig. l, and Fig. 4, a pers1ective view of the device.

Like characters of reference designate like parts in the several. figures of the drawing.

Referring to the drawing, A designates a railspee'ifieat ion of LettersIPatent;

railroad rail of l' section. and B one of the cross ties on which the tlll is supported.

The anti-creeping device of my invention is preferably made of a, single pieee or sheet; of rolled metal bent so as to provide a Hat plate C which intervenes between the base D oi the rail and the cross tie l3, and so as to provide an upstanding web E which is designet'l to lie close to the upstanding web F of the rail; the intervening metal G of the antiereeper having: approxinmtely the slant of the upper surface of the base flange so that a jaw is nrovided into which one of the base flanees tits. The web Pl formed with a pertoration It and the web ll? ol? the rail is similarly pertoratm'l, the rail being positively attached to the anl'ia-recper by a bolt I passing through these pertoratimis. The nietal. oi. the anti-creeper will preferably have some elasticity so that by making the jaw a trille narrower than the base flange of the rail the drawing up of the nut J on bolt I will produce a fllCl'lOl'lll grip of the anticreeper on the rail. A portion of the forward edge of the plate 7 bent down so as to novidc a flange 1: which is designed to abut against the Face of the tie ll.

'l'he device is preferably spiked to the tie by ordinary railroad spikes and to this end is provided with the spike holes L in the jaw portion of the device and the spike hole M in the opposite edge of the plate C.

in order to further in reaw the frictional grip of the device on the rail the edge oi. the plate C opposite the jaw formed with slits It and portions of the edge ot the plate, desltfllnltll U and l". are bent up a trifle. This bending preferably done after the anticreeper is put in plate on the rail, with the result. that the rail is :l'urther crowded into the jaw, although ii. desired the lugs may be bent up when the device is manufactured.

Q designates the spikes used for securing the device and the rail to the cross tie.

it will be observed that the device can be made of a single rectangular piece of rolled stock. This piece of metal has simply to be punched, slit and bent into the desired configuration. 'lhere'lore the device can be ver rhcaply lnanuttmturer. It serves the fun t-ion both of a tie plate and anti-ereepe r. Its hold on the rail is positive. Atthe same time there is no danger that undue stresswtll loosen the bolt connection or shear otit' the bolt inasmuch as the frictional grip of the device on the rail relieves the bolt of some of the stress to which it otherwise would be sub jected. As the device engages the two faces of the tiethe front vertical side and the top surface-and is, furthermore, spiked down to the tie, there is no danger that the gripping action will cant the tie. But even if such canting should take place the tie plate portion of the device will not be turned as is the case with separate tie plates used in connection with the types of anti-creepers now in common use. The lugs O and P, when bent into their oblique position, tend to'increase thefrictional grip of the device on the rail. The tendency of the rail to creep forward takes place, of course, while the train is passing over the rail in question. The passage of the train necessarily develops some vibration and lateral stresses and whenv these are absorbed, as they are to a certain extent bythe lugs O and P, the tendency to longitudinal creep is checked. The spikin of the device to the tie and its frictiona grip on the rail check any tendency there may be to creeping in the opposite direction, that is, in the direction away from the tie in question.

I claim:

1. A device of the character described comprising a plate intervening between the base of the rail and one of the cross ties on which the rail is supported, a web adapted to be bolted to. the upstanding web of the rail, means providing a jaw adapted to take a frictional grip on one of the base flanges of the rail, and a lug or lugs at the edge of the plate opposite from said web which are bent up to a position oblique to the rest of the plate, for the purpose specified.

2. A device of the character described comprising a plate intervening between the Y base of the rail and one of the cross ties on spike holes whereby it may be spiked to the track.

3. A device of the character described base of the rail and one of the cross ties on which the rail is supported, a web adapted to be'bolted to the upstanding web of the rail, means providing a jaw adapted to take a frictional grip on one of the base flanges of the rail, a lug or lugs at the edge of the plate opposite from said web which are bent up to a position oblique to the rest of the plate, and a depending flange in position to abut against the tie. v

A device of the character described comprising a plate intervening between the base of the rail and one of the cross ties on which the rail is supported, a web adapted to be bolted to the upstanding web of the rail, means providing a jaw adapted to take .a frictional grip on one of the base flanges of the rail, a lug or lugs at the edge of the plate opposite from said, web wnich are bent up to a position oblique to the rest of the plate, and a depending flange in position to -abut against the tie, said device being formed with spike holes whereby it may be spiked to the tie.

5. A device of the character described consisting of a single sheet of metal bent so as to form a jaw for one edge of the base of a rail, a plate extending under the base of the rail and projecting beyond the other edge thereof, and an upstan ing web adapted to be bolted to the vertical web of the rail, one of the transverse edges of the device being formed with slits and the metal between the slits bent down so as to provide a depending tie-abutting flange.

6. A device of the character describedconsisting of a single sheet of metal bent so as to form a jaw for one edge of the base of a rail, a plate extending under the base of the rail and projecting beyond the other edge thereof, and an upstanding web adapted to be bolted to the vertical web of the rail, one of the transverse edges of the device being formed with slits and the metal between the slits bent down so as to provide a depending tie-abutting flange, theedge of the plate opposite the jaw being formed with slits so as to provide bendable lugs.
