. new and useful Improvements in Anticreepers, of which the following is a specification.

The construction, application and operation of my improved anticreeper are herein fully set forth, reference being had to the accompanying drawings which form a part hereof and in which- Figure l is'an end elevation'of my improved anticreepenthe base and a portion of the web of the rail to which it is attached being also shown. Fig. 2 is a side elevation anticreeper, showing a portion of a tie against which one member of the anti portion of the rail-base,

creeper abuts in its restraining action. 3 is a section on line II III of Fig. l. Flg. 4; is a side view of the rail-grippln jaw.

(This is the left-hand jaw of Fig. '1. Fig. 5 is a plan view "of the tie-abutting jaw, looking in the. direction of the arrow V in Fig. 2. (Tl1is is the right-hand aw in Fig. l.) The same reference letters indicate identical parts in all the views.

As will readily be seen from an inspection of the drawings, my anticreeper-consists of two interlocking members 1 and 2, which are designed to bear against the lateral edges of the base of the rail 3 and to cooperatively exert a clamping action-thereon. In addition to said lateral clamping action, jaw 1 also exerts a vertical gripping action upon the upper and lower faces of the contiguous which will be presently explained, and because of this gripping action, said jaw 1 will be herein referred to as the gripping jaw.

In addition to the lateral clamping action of jaw 2, the lower end of said jaw is adap-ted to abut or bear against a cross-tie 4 of the track, iira manner and for a purpose which will presently be explained; and because of this abutting function, jaw 2 will be referred to as the f. abutting jaw, asby the use of these terms the two members will be clearly and-concisely differentiated, especially in the claims,'shou ld it be found desirable to employ them thus.

The construction, in detail, cree of t j of my anti-- er is substantially as follows: The gap as gripping jaw 1 is provided with convex,

against which they bear. "obliquely inclined, vertically, as a whole, to

opposing, rail- engaging faces 5 and 6 which lie obliquely to the respective upper and lower surfaces ofthe rail-flange or base Said gap is also the longitudinal dimension of the railfiange, as will be clearly seen by a reference to Fig. 4, which causes the anticreeper to as sume an obliquity of position with reference to the rail when afiixed thereto, and to extend obliquely downward toward the tie against which it abuts, so that the lower portion only of the anticreeper bears against the tie. The faces, 5 and 6 bear firmly against the top and bottom of the contiguous portion of the rail-flange respectively and exert a gripping action and because of this gripping action, the creep of the rail tends to carry jaw 1 with it. This tendency of jaw l, and more specifically the upper portion thereof, tomove with the rail, together with the abutment of the lower-portion of jaw 2 against the tie and restraining such movement, tend to cause a rocking movement of the jaws, and this tendency to rock causes the faces 5 and 6 to more firmly bear against the upper and lower faces of the'rail base and to increase the vertical the rail flange. The contact points of the faces 5 and 6 are staggered, the contact point of the upper face 5 being somewhat in advance of the contact point of the lower face ,6 so that the rocking tendency aforesaid causes said points of contact to more firmly grip the rail between them. The abutting jaw 2 is also provided with a gap, the upper lip 7 of which bears against the upper surface 'of the rail-base, but this jaw does not bear against the bottom ofsaid base. The upper surface or hp 7 of said 7O upon the" rail,

gripping action of this jaw upon gapis obliquely convex, the same as jaw 1,

but serves principally as 'a'r'etaining means to keep the jaws in position.

The interlocking features of the jaw's'l and 2 are constructed as follows: Jaw l is provided with a T-shaped slot or gap 8, adapted for the reception of the T- shaped head 9 of jaw 2; the impinging faces of said slot and headare obliquely inclined-relative to the longitudinal dimension of the rail 3, so that when the jaws are drawn together so that I placed in engagement or the interlocking position, they are creeper 1th it, and-the they clamp the edges of the rail-base lee-- ting against a tie t. The-gripping aw 1 is then placed in position and interlocked with jaw 2 by striking it several blows with a hammer or sledge upon 10, and this, because of impinging vfaces ofthe interlocking device aforesaid, causes the jaws to firmly bear upon the edgesof the rail-base and'clamp said base between them. The jaws are so designed that when they are. interlocked upon the rail, they will stand in about the relative position shown in Figs. 2, 3- and 5, so

that the gripping jaw 1 is farther from the tie than the abutting jaw and cannot come in contact' therewith.

The direction of creep of the rail, relative to the position of the vanticreeper, is toward the tie, as indicated in Fig. 2, and as the creep of the rail tends to carry the antiabutment of jaw 2 against thetie' counteracts and restrains this tendency, there is thus set up a tendency of the anticreeper to rock uponu the rail-flange, this causes the opposing points 5 and 6 of the jaw 1 to grip the flange or base of the railmore firmly between -them,- and this action in turn causes 'a more decided tendency of'jaw' 1 to .move with the rail and a more complete interlocking of the jaws. It will thus be seen that all the, stresses brought to bear upon my anticreeper in actual servicetend to increase its efiiciency and restraining or anticreeping action upon I the rail.

I claim- 1. In an anticreeper the combination of two interlocking members cooperatively clamping the rail-base laterally between them, 'a gap in one of said members, staggered points of contact upon the opposing faces of saidgap adapted to bear upon the upper and lower faces respectively of said rail. base, the lower end of the other jaw being disposed to abut against a tie, whereby PP the striking boss lower 'end'of the other jawabemg'disp'osed the obliquity of the of-the rail Wlll, cause sald rnembersto more to assume a vertically oblique position,

the creeping tendency, of the rail tends to impart rocking action to the anticreeper. 2: I an-anticreeper'the combination of two interlocking members arranged to cothe rail base between operatively clamp them, a gap in one of said members adapted to receive one edge of the-rail base, stag-l on the} opposing to bear-upon the base',.t he

gered points oi-lcontact u aces ofsaid gap arrange er and lower faces of said rail tojabut against a tie, the interlock ng deviceofi'e said jaws r'having obliquely inclined 1111-. ing faces, .so'that'the' creeping'te'ndency firmly interlock. v

3. In an 'anticreeper the .combination of two interlocking members arranged to clamp the rail base laterally between them,

an obliquely-inclined gap inone of said members adaptedto receive one edge of-the rail base and to cause the anticreeper to assume a vertical obliquity of position, there being staggered points of contact upon the opposing races of said gap, the lower end of the other jaw being adapted to abut against a tie whereby the creeping tendency of the engaged lrail will tend to impart a rocking action to the anticreeper and-cause said points of contact to more firmly bear upon the rail base.

4:. In an anticreeper .the combination with a rail and a tie of two interlocking jaws adapted to clamp the rail base laterally between them, a gap in one of said jaws adapted for the reception ofone edge of the rail base, staggered points of rall contact in said gap whereby the anticreeper is caused t e other jaw being arranged to bear atv its lower end against said tie whereby the restraining action of the anticreeper will tend to cause it to rock and said contact points to more firmly bear against the rail.

In testimony whereof I afiix my signature in "presence of two witnesses.
