ANTICREEPER FOR RAILWAY RAILS.

Application led July 3, 1922. Serial No. 572,477.

To all 'LU/0m t may concern:

Be it known that I, WILLIAM S. liVns'roN, a citizen of the United States, residing in the city of Dallas, county of Dallas, and State of Texas, have invented certain new and useful Improvements in Anticreepers for .Railway Rails, of which the following is a full, clear, and exact description.

My invent-ion relates to anticreepersfor railway rails of the type having a. trans` shoulders adapted to bear against the opposite rail base edges, and which, in installation and functional operation, isv slightly rotated in a plane parallel to the bottom surface of the rail base in a manner to bring the shoulders to their bearings and thereby to establish a lever grip on the rail. M v invention relates more particularly to a form spring clamp type similar in many respects to that illustrated in U. S. Letters Patent No. 1,120,258 granted to me Dec. 8th, 1914, and No. 1,257,566 granted to me Feb. 26th, 1918, in which three primary points of bearing on the rail are provided for and in which t-he manufactured form is smaller than the base of the rail on which it is to be sprung in the process of in` stallation.

My present invention is embodied in a spring clamp V form made in two pieces, and my object is to provide in combination, a transverse bar member with unyieldingl shoulders for bearing against the opposite rail base edges so place'd in position as to have a lever grip on the rail opera-ting in a horizontal plane, and a separate longitudinal member adapted to be sprung into place to hold the transverse bar in operative position and to transn'iit the tie reaction thereto. The novel construction whereby l. att-ain this object and other novel features of improvement are hereinafter described and clearly illustrated in the accompanyingdrawings which form a part of these specifications and are particularly pointed out in the claims.

ln the drawings Fig. l is a side elevation of a rail showing the anticreeper in position against a tie. Fig. 2 is an elevation transverse to the rail as seen from the left of Fig'. l. but with the tie omitted. Fig. 3 a plan or downwaig'd view with the rail and tie shown in full lines, Fig'. is a plan view partlyy in section on the line Fig. l, the rail base outline being indicated by dotted lilies. Figs, 5 and 6 are pla-nv views to illustrate initial installation positions of the parts of the device in the process of bringing it to the final position shown in the first four figures. ."ig. 7 is a plan view illustrating the shape of the device as manufactured and the two members assembled ofl' the rail, and shows that the seating space is narrower than the rail base on which it is to be sprung when installed. The same letters and numerals of reference indica-te the same parts in the several views.

Described in detail the device consists of a transverse bar member B with shoulders l and 2 bearing against opposite edges of the rail base and a longitudinal member C adapted to be snapped into position on the bar and the rail and have concentrated bearing against one rail base The three points of bearing l, 2, and 3 constitute a rail seating' space narrower than the rail base if, before :installation on the rail, the two members B and are assembled in their manufactured shape as shown in Fig. 7. ln t e process of installationl this space is expanded by installation provides for initial grip between the rail. In respect to tl l, 2, and

a permanent anticreeper and the 1e points of bearing 3, and the resilient action just dewill be noted that my vention embodies a fundamental feature of t e devices described referred to.

i It is provided with a. top iiange 5 `overlapping the base iiange of the rail R, and a bottom flange 6 passing beneath the bar B. It is sleeved over the end of the bar B which in installation is caused to pass through a hole 7 partl)v formed when the part el in the shape of a tongue is punched from the vertical face into a position under the rail with its end bearing against the back of the bar B. The forward edge 8 of this hole is designed to take a seat inside of a shoulder' 9 on the forward side of the har The distance between the edge 8 and the end of the tongue elis expanded at installation, andthe resilient quality of the .elmpe tends to rotate the member C from the position of Fig. l to that of Fig. 7.

llO

vThe resilient action of the tongue et holds To prevent the bar 'from dropping away from the rail the end with shoulder l on the opposite side ot' the rail from member is provided with a lip slightly over-hanging the base ange. The end with shoulder 2 is prevented from dropping away by the 'bottom flange 6 of member C. A cross section of member' C taken adjacent the edge 8 is indicated by the dotted outline in Fig. 2.

At installation the bar B is first passed beneath therail substantially at right angles thereto as shown in Fig. 5 so that the lip l() can be' hooked over the base flange andthe body of' the barl brought up aga-inst the bottom of the rail. The bar is then rotated in the direction indicated by the circular arrow in Fig. 6, a small amount to an angle with the rail. something less than ninety' degrees, until the shoulders l and Q take a. firm unyielding bearing against op posite edges of the rail base. rlhe member C is then placed by hand on the end o t the bar in the position shown in Fig. (i with the forward end adjacent the point resting against the rail base edge. Hammer blows are then applied to niemiier C. first near the center and in the direction indicated by the arrow l2, and finally as indicated by the arrow i3, until it takes the position ot Fig. 4. In this process the tongue e is sprung something beyond the amount indicated by the dotted outline in Fig. G until the edge 8 clears and can drop in behind the side shoulder 9 of the bar. T he tongue then recovers part ot the distance through which it lwas sprungand operates. to hold the edge 8 in its seat behind the shoulder 9. .lt will be observed that the reaction between the end oli' the tongue 4 and the edge 8 tends to rotate the bar B still further in the dirertion indicated by the circular arrow il. and thereby maintains the lever grip on the rail with the shoulders l. and Z actingr as the iiilcrums. The reaction of the tongue is utilized also to take up any effect of loosenessl that might arise from any slight variation 'from the normal width of the rail Vsection on which the anticreeper is to be used.

The forward end of the member C adapted tov bear aga-inst and receive the reaction thrust of the tie T is preferably provided with a flange it to stiften the shape and in crease the tic abutting surface. To preventvcrtical movement of this end of the ineinb-er, due 'to friction against the tie as the rail rises and lowers under the pz sing load. the 'forward portion ot the vertical 'tace is pressed inward and under the rail. base et .15. By this construction a short flange enh bracing jaw 16 reenforced by the flange let is 'formed on the forward end of member l By this construction also the center line oi the tie reaction thrust is brought slightly beneath the rail base edge as indicated by the arrow 17 in l? ig.

In func-tional operation the tie reaction is transmitted by member C to the bar through the seat of the edge 8 behind the shoulder 9 and thence to the rail through the medium oi' the lever grip of the b ar on the rail already established at installation, as described. That this is a genuine lever grip is clear from the fact that the tie reaction thrust is transmitted to the bar just inside the shoulder 9 and at a point relatively out side the two tulcrums l and 2, rather than at any point between these iiulcruins. ue1 cause ot its length and shape the member t in itself will have littley or no grip on the rail through the establishment of a lever grip acting in a vertical plane7 and a high percentage of the total reaction thrust will be transmitted to the rail through the bar B. 'll he bar andits shoulders therefore are made as heavy and unyielding as may be necessai lliith the center line of the tie reaction ly' ing within the shoulder 9 for normal opera' tion parallel to the rail it is to be noted that there will be no tendency to open up the angle oft the l\/ formed bythe lines of connection between the three bearings l, 2. and B. ln operation if the shoulders at 'l and 2 be come slightly embedded in the rail base edges the Vbar is rotated still turther in the direction of the circular arrow il, reducing the angle of the V. This reduced angle wil be maintained by a further recovery of the resilient tongue lt is especially to be noted that'the functional operation does not add to the strain in the tongue 4i. ln the action inst described the strain is gradually relieved as the device becomes embedded to its seats.

To set the anticreeper close up to the tie hammer blows may be applied to the end of thc bar B on the side carrying the longitudinal member andv ina direction toward, the tie as indicated bv the arrow Fig. Il. rl1 o move it away from the` tie hammer blows may be applied to the other end in the direction indicated by the arrow 'llo remove the anticrecper from vthe rail it is first backed away from the tie a slight amount. Then a pinch bar or other tool is used to hold the end of the bar B adjacent the shoulder. but not too close to the edge fi of .inemlier/(. and a. sharp hainiiici' blow applied `to iiicinlier t :is inilicatcd liy thc ari-ow 29. 'lfhat will cause the edge io snap ont troni behind thi` shoulder 9.

installation and rcnioval tween the end ot the tongue i and the edge ll' through lrciliieiit the distance be 8l becomes too great to be efl'ective itl may be closed? up easilyl with ahammer.

lA feature of importance attained by the novel construction of my two `piece anticreeper is the provision against the loosen*- ing oi"v the device, from the rail' should the rail creep backwardin the opposite direction from that indicated" by the arrow 2l in Fig.. l. In case the anticreeper is embeddedv in frozen ballast and the rail moves. backward the member C acts onthe bar B with the same result as from the hammer `blow appliedy at point 18, and the deviceis retained in `its position against the tie. This action illustrates the fact that the device, `when held to the tie by the ballast or by any means acting similarly on the member C, as for example` another tieplaced against the other end `opposite the tie T, the device will per- `form the full function of' a lever grip mechanism, or as sometimes called a shackle mechanism, holding the t ing gripped against movement in one direction and freeingit for movement in the opposite direction.

hanges may be made in the exact form of either or both members without changing the method and principle of installation and operation. l therefore claim broadly, as well as in combination with other features, a two piece anticreeper for railway rails comprising a transverse bar member with unyielding shoulders adapted to bear directtained bearing between it and the transverse member, and adapted to transmit the tie reaction thrust through the transverse member and the lever grip to the rail; the reaction in said spring retained bearing between the members operating to establish and maintain said lever grip.
