RAIL ANTIGBEEPER.

Application filed May 29, 1925, Serial No. 33,638.

The object of the present invention is to provide a new and improved anti-creeping device constructed to grip the rail, and which when used in the ordinary manner of rail-anchors abuts against a tie so that the longitudinal movements of the rail in one direction are transmitted to the tie, and which when used vith a suitably constructed tie-plate transmits to the tie the longitudinal mov ments of the rail in both directions caused by reversal of traiiic or by the expansion and contraction of the rail or by its reaction from the wave movement of one-way trafiic.

In the accompanying drawings Fig. 1 is a top plan view of a device embodying my invention assembled in place on a rail and against a tie; Fig. 2 is a View partly in side elevation and partly in section on the line 2-2 in Fig. 1; Fig. 3 is a view showing one end of the device in place on a rail with a portion of a tie in section; Fig. 4 is a detail view on the line &i in Fig. 2; Fig. 5 is a view similar to Fig. 1 showing the device as sembled in position with a form of railway tie-plate with which it may be used; Fig. 6 is a view partly in side elevation and partly in section on the line 66 in Fig. 5, and Fig. 7 is a view showing one end of the device in place on a rail with part of the tie-plate and with a portion of the tie in section.

In the drawings the reference letter A designates the head of a rail, B its base and 0 its web, and D is an ordinary wooden tie.

The anchor consists of a rectangular metallic plate having a flat base or body 1 which is provided at one end with an overhanging lip 2 and at the other end with a rail-abutting shoulder 3 which is preferably rounded off or slightly beveled at its upper inner edge. The dimensions of the anchorplate are such that when assembled upon a rail-base one edge of the latter fits under the lip 2 and the other edge abuts against the shoulder 3, the rounded or beveled upper edge of the shoulder permitting the rail-base to pass down to place. The anchor-plate is provided with a longitudinal central slit 4 which passes through its lip 2 so that the two wings thereby formed may be spread laterally apart when a suitable wedge 5 is driven to place between them, and the two jaws formed by the split lip may be spread apart to engage the rail-base. The end of the plate carrying the lip is extended so as to form a seat for the wedge well within the Renewed June 1, 192?.

area of the body of the plate itself. When the anchor-plate is assembled upon a rail base and the wedge is driven into its seat the lateral jar-5s formed by the split lip are spread apart so that the outer edges of their undercut portions bind on or bite into the edge of the rail-base as shown clearly in Fig. 4, and the outer under corner of each portion of the jaw binds or bites into the upper beveled face of the rail-base as shown in Figs. 2 and 6. By thisconstruction theengagement of the lip 2 with the rail-base holds the shoulder 3 in engagement with the other edge of the rail-base, so that the an-- ehor-plate firmly grips the rail. In practice the anchor-plates are assembled upon the rails in position to abut against the ties, so that the longitudinal movements of the rail in one direction are transmitted to the ties. which resist the same as they are embedded in the ballast. In practice I prefer to form the anchor-plate with a depending wing 6 on the side which abuts against the tie in order that the vertical motion of the rail due to its wave-like movement under traffic may not raise the anchor-plate above the line of. the upper surface of the tie. The anchor-plate is assembled on the rail-base by passing it beneath the base and hooking its lip 2 onto one edge thereof, when the opposite end is moved up until the corresponding edge of the base seats against the shoulder 3, and the wedge 5 is then driven to place in its seat.

In the form shown in Figs. 5, 6 and 7 the anchor-plate is combined with a suitable tie-plate to form a two-way anti-creeper. The tie-plate E is formed of metal and is of sufficient size to provide a suitable seating surface for the rail-base and to have one of its sides extend beyond the side of the tie as shown for example in Fig. 5 when the plate is spiked thereto in track as at e. The extended or overhanging end of the tie-plate is provided with a transverse recess E which is long enough to readily admit the anchor-plate into position therein; these dimensions may be so related as to allow the anchor-plate sufficient endwise play in the recess to assemble and disassemble it in position on the rail-base while the latter is spiked to the tie as shown in Fig. 2, or they may be so related that the anchor-plate after being assembled on the rail-base can be dropped into the recess when the rail is placed on the tie-plate with its ends abutting the ends of the recess as indicated in Fig.

6 to enable the anchor-plate to resist side thrusts of the rail. The recess in the tieplate is of sufficient width to receive the anchor-plate in assembled position therein and to fit against the outer ends of the jaws of the anchor-plate when the latter are spread by their wedge as shown in Fi 5; these dimensions preferably are such that the sides of the anchor-plate will fit snugly against the side walls of the recess to enable the anchor-plate to abut against the tieplate in either direction without undue lost motion or play. In this use of the anchor plate I prefer to form it with opposite depending marginal wings 6 as clearly shown in Fig. 7', so that the sides of the anchor plate will not rise out ofthe recess of the tie-plate under the vertical action of the rails due to their wave-like motion from passing traflic. The anchor-plate grips the rail and snugly fits the sides of the recessin: the tie-plate, so that the anchor'plate will transmit all longitudinal movements which the rail may have in either direction to the tie-plate, and as the tie-plate is spiked to the tie the latter resists longitudinal movement of the rail in both directions: By this organization a railanchorage is provided which resists rail creeping in both directions as it interlocks the rail and tie so that all movements of the former are transmitted'to the latter.

Inboth uses of the anchor-plates the clepending side wings abut against the sides of the ties to transmit the lengthwise stresses of the rail directly against them.

I claim:

I. A rail anti-creepercomprising a base having a rail shoulder at one end and an overhanging lip at its other end, the base being' provided with alongitudinal slit extendin'g throughsaid lip to form opposite lateral jaws, and a wedge to spread the jaws.

2'. A rail anti-creeper comprising a base having a rail shoulder at one end and an overhanging hp at its other end, the base having a depending side wing and being provided with a longitudinal slit extending through said lip to form opposite lateral jaws, and a Wedge to spreadthe jaws.

3. A rail anti-creeper consisting of a tieplate constructed with an extension projecting beyond one side 01' the associated tie and having a recess transverse to the length of a railbase and longer than the width of said base, and an anchor-plate extending across the underside of the railbase and fitting within said recess, said anchor-plate having rail-engaging members adjacent its ends and having a longitudinal slit extending through one end and dividing the associated railengaging member into sections, and a wedge to spread said sections.

4r- A rail anti-creeper cons sting of a tieplate constructed with extension projecting beyond one side of the associated tie and having a recess transverse to the length ot a rail-base and longer than the width of said base, and an anchor-plate fitting within said recess and extending across the underside of the rail-base and having a shoulder at one end and an overhanging lip at its other end, said anchor-plate having 21 depending side wing and a longitudinal slit extending through said lip to form lateral jaws, and a wedge to spread the jaws.

5. A rail anti-creeper consisting of a tieplate constructed with an extension projecting beyond one side of the associated tie and having a recess transverse to the length of a rail-base and longer than the width of said base, and an anchor-plate fitting within said recess and extending across the underside of the rail-base and having a shoulder at one end and an overhanging lip at its other end, said anchor-plate having depending side wings and a longitudinal slit extending through said lip to form lateral jaws, and a wedge to spread the jaws.

In testimony whereof I hereto aiiix my signature.
