BASE-PLATE FOR RAILWAY-RAILS.

Specification of Letters Patent.

Patented J an. 11, 1916.

provide a support therefor which will pre vent the rails from spreading or creeping;

which will largely prevent the rails from breaking and will hold them inplace even though they break or crack; wh1ch Wlll efflciently support the rails between the ties and resist all stresses on the rails; which permits the use of very light rails and reduces the number of ties required; and which may be used with wooden, steel or other ties. Other objects will appear hereinafter. Referring to the accompanying drawings, Figure l is a'plan of a rail-base broken off at each end and supported on ties shown also broken off at their ends; Fig. 2, a side elevation of Fig. 1; Fig. 3, a section on the line IIIIII, Fig. l, a rail being shown in normal position; Fig. 4, a section on the line IVIV, Fig. 1; Fig. 5, a perspective view of a portion of a base-plate on a tie and with a rail thereon; Fig. 6, a plan of two baseplates with interlocking ends; and Fig. a view like Fig. 6, only the interlocked ends are separated somewhat. Fig. 8 is a plan of a portion of a rail-joint, showing my improved anti-creeper applied thereto; Fig. 9, a. cross-section of Fig. 8 on the line IXIX,

the flanges on the base-plate being omitted;

Fig. 10, an elevation of the anti-creeper; and Fig. 11, a plan thereof.

On the drawings, I show two steel baseplates 1 and 2 interlocked over the right hand tie 3, the base-plates having holes 4 through which suitable fastenings may be driven into the ties. The portions of the base-plates over the ties or equivalent supports conform to the shape of the ties or supports. I have shown the ties flat on their upper surfaces and therefore show the pori tions of the base-plates resting thereon also flat; but in order to stiffen the base-plates and to provide means for guarding the rails, I provide the portions of the base-plates between consecutive ties with upturned lateral flanges 5 pressed towardthe center line of the base-plates. The distance between opposite flanges or guards 5 equals the distance between the edges of the rail flanges 6 (Fig- 3) of the. rail 7. The upper edges of the flanges 5 may be turned outwardly to form the ribs or sub-flanges 8 in order to bring the top of the flanges 5 below the level of the usual bolt holes (one, marked 9, shown on Fig. 3) for flsh-plates and to strengthen the base-plates against lateral strains. The base-plates are made from rectangular strips of metal and the flanges 5 are pressed up out of the normal sides of the strips. This manner of making the base-plates may cause the flanges to stand opposite the bolt-holes in the rails and fish-plates unless the upper portion of the flanges are turned down as described.

The rails may be secured to the ties and base-plates by the usual spikes, one marked 10 being shown on Fig. 5 driven through the base-plate and into the tie. plates are preferably provided with the ribs 11 pressed downwardly from the center thereof between consecutive ties to strengthen the base-plates.

I prefer to secure the ends of the baseplates together. This can be accomplished in many ways but I prefer that the ends be interlocked adjustably. I have provided the ends of the base-plates with the end tongues 12 and the recesses 13, one edge of each tongue and of the recess having the teeth 14. of uniform dimensions arranged longitudinally of the base-plates. The tongues and recesses .are arranged and proportioned so that the tongue on one base-plate will fit the recess in the adjacent base-plate as shown on Fig. 6, the teeth on the two baseplates interlocking. As shown on Fig. 7, the ends of the base-plates may be separated somewhat and still remain interlocked. By providing an adjustment between the ends of the base-plates, I can keep the flat portions of the base-plates in register with the ties on curves. As the distance on the outer rail of a curve is longer than on the inner rail, the flat places on the base-plates would fall back out of line with the ties on the outer side of the curve, if the flat places match the ties on the inner side of the curve, unless provision is made for advancing the ends of the outer base-plates. It is seen that, by making the proper adjustments between the ends of the adjacent base-plates on the outer The baseside of curves the flat places can be kept substantially central over the ties.

This application is a continuation in part of my application, Serial Number 867,994, filed October 22, 1914:.

Referring now to Figs. 8 to 11, the rails 7 are shown seated on the base-plate 1. The fish-plates 12 are secured to the rails by the bolts 13 in the usual manner.

My anti-creeper 14 comprises a casting or forging having on its lower side the lug 15 which extends into the opening 16 on the base-plate adjacent to the rail flange. This lug occupies the outer end of the opening 16, the outer wall of the opening serving as an abutment to maintain the anti-creeper in a fixed position with respect to the rail. The anti-creeper has on the edge thereof nearest the rail the teeth 17 arranged to bite into the flange 18 of the adjacent fish-plate. The side of the anti-creeper nearest the rail has the slot or opening 19, arranged to register with the part of the opening 16 which lies between the lug 15 and the rail. The spike 20 is driven down through the openings 19 and 16 and into the tie 3, the head of the spike engaging the top of the flange 18 and anti-creeper 14, whereby the latter is held tightly in place on the base-plate and with its teeth 17 firmly gripping the edge of the fish-plate. I have shown two of my anticreepers secured at opposite sides of one of the rails.

I claim 1. In a railway, continuous steel baseplates supporting the rails the entire length of the latter, and means integral with the base-plates whereby the ends of two baseplates may be adjustably locked together in differenent relative longitudinal positions and thereby prevented from relative longitudinal movement.

2. In a railway, continuous steel baseplates supporting the rails the entire length of the latter, and interlocking teeth on the ends of the base-plates, the teeth being arranged in lines parallel with the base-plates,

whereby the latter may be secured together in different relative longitudinal positions.

3. In a railway, continuous steel baseplates arranged end to end and supporting the rails the entire length of the latter, and tongues projecting from the ends of the base-plates and having interlocking teeth arranged in line with the base-plates, there being a recess in the end of each base-plate to receive the tongue on the companion baseplate.

4. In a railway, cross-ties, and continuous,

steel base-plates thereon supporting the rails the entire length of the latter, the opposite edges of the base-plates between consecutive cross-ties being turned upwardly and forced toward each other, and railway rails having their flanges engaging the opposing faces of the said upwardly-turned portions of the base-plates.

5. In a railway, cross-ties, continuous steel base-plates thereon supporting the rails the entire length of the latter, the opposite edges of the base-plates between consecutive crossties being turned upwardly and forced toward each other, railway rails having their flanges engaging the opposing faces of the said upwardly-turned portions of the baseplates, and outwardly turned flanges on the top of the said portions and below the bolt holes in the rails.

6. In a railway, cross-ties, continuous steel base-plates thereon supporting the rails the entire length of the latter, the opposite edges of the base-plates between consecutive crossties being turned upwardly and forced to- Ward each other, railway rails having their flanges engaging the opposing faces of the said upwardly-turned portions of the baseplates, and ribs pressed downwardly from the base-plates between the ties and arranged longitudinally of the base-plates between the edges thereof.

Signed at Pittsburgh, Pa., this 4th day of May, A. D. 1915.
