.Eb all whom t may concern.

Be it known'that l, EDWARD LAAS, a citi- 'lL-.n of the United States, residing at Chicagp, -in the county of Cook and State of lllilois, have invented certain new and useful improvements in' Lrnticreepers,lof which the following is a specification.

My invention relates to an anti-Creeper, that is, to a device 'to check the Vtendency of railroad V:rails to creep longitudinally; and. the principal object of the invention is to preferably a oneliable holden the rail,whicl 1 will be strong enough to withstand the very considerable .when the rail.y sta. es to'creep and which, furthermore, will be .light in weight, inexpen-` sive to manufacture and can be conveniently applied to the rail, and which lmay be removed therefrom if occasion require it. lbreferably also my device when on the .rail .vill have a grip thereon at all times, tending to increase under creeping strain. l

Among the advantages of a one-piece anti- Creeper' are cheapness of manufacture, convemence 1n handling,

and impossibility .of erroneous assembling of parts. However, diiiculties have been experienced in constructing a one-piece device which willmaintain 'its hold on 'the 'rail as against various ydisturbing inuences towhich an anti-creep- `ng device is necessarily subjected and especially when the deviceis not under creeping pressure. Among there influences are the vibration of the rail, Vits tendency to contract so as to vdraw the device out of contact with thetie which it abuts, the differences in expansion' and. contraction' as between the rail and the anchorwhieh occur because of temperature changes, andthe tendency of the rail to re-act after being relieved from the forward or creeping stresses. ,There is also the likelihood of the position of the device on the rail' being disturbed either accidentally or otherwise by persons working on the roadbed. My present invention provides an anti-creeping device capable of construction in one-piece, but not necessarily so, an so constructed that when once applied to the rail there is little or no chance of its hold thereon being loosened from any of the above causes. l

Lightness in fr consideration l leht is also an/ important device of this sort since n a device issubjected Vpreferably steel, which is 16 i7 suiface of the base iange, are bent forwardly rail anchors are used in such large numbers and are transported over such considerable distances so that cost of material and freight rates forman important factor in the price paid by the railroads.

My invention consists in certain novel arrangements and constructions, to be hereinafter described `and claimed, whereby the above stated'objects, and such other objects as will hereafter appear, are obtained.

My invention is illustrated, in certain preferred embodiments, in the 'accompanying drawings whereinf Figure l is a plan view of an anti-Creeper constructed in accordance with the invention shown as applied to a rail. y

Fig. 2 is a side elevation of the device showing the rail in section. l

Fig. 3 is a sectional view von line 3 3 of Fig; 2.

Fig. 4 is a view, in perspective, ofthe rail anchor 'shown in the preceding ligures.

Fig. l51's a view, similar to Fig. 2, illus- Y trating a modication.V

Fig. 6 is a view, in perspective, of the modified form of device.

Fig; 7 is a plan view illustrating another modification.

Fig. 8 is a side elevation of the same, and

Fig. 9. is a sectional view on line 9-'9 of Fig.\8.

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

Referring to the drawings, A represents, `a railroad rail and B one of the cross ties on which the rail is laid.

Having reference particularly to Figs. 1 to 4 inclusive, the anti-Creeper shown in these igures consists of a bar 10 of metal arranged edgewise of the rail and is formed at opposite ends with means forengaging the edges of the base flange of therail. When the device is made in one-piece, as shown in these figures, one end of the bar l() is bent around, as indicated at 1l, to form a tiel abutting member l2, the extremity 13 of which bears against or comes very close to the body portion of d bar l0. The lient portion of the device is.

notched at'li,

I l5 to receive one side of the base flange of the rail. Preferably the lugs which hear upon the upper inclined as shown, so that when 'the and backwardly angularly with respect to device is moved Cit with. aplocking tongue notched for engagement with the rail base extending backwardly away from the tie which, when the device is in place, bears with spring action against the rail,

A one-piece anti-Creeper provided at one end with a pair of spaced rail engaging jaws and at the other with a flexible locking tongue which, when the device is in place, bears with sgring action against the rail.

4f. A one-piece anti-Creeper provided with a tie abutting part and at one end witha pair of spaced rail engaging jaws,'and at the other with a locking tongue extending backwardly away from the tie which, when the device is in place, bears with spring action against the rail.

A one-piece anti-Creeper provided with a tie abutting part and at one end with a pair of spaced rail. engaging aws and at the other with a locking tongue notched for engagement with the rail base extending backwardly away from the tie which, when the device is in place7 bears with spring actiongainst the rail.
