RAIL-ANCHOR PLATE.

Application filed March 3, 1924. Serial No 696,427.

To all whom it may concern:

Be it known that I, WARREN M. Osnonn, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, having invented certain new and useful Improvements in Rail-Anchor Plates, do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to improvements in tie plate structures for anchoring railway rails, and its object is to provide a novel and useful organization which looks the rail to the tie-plate in an improved manner.

The invention consists in the matters hereinafter described and then pointed out in the claims.

In the accompanying drawing, Fig. 1 is a perspective view of the plate; Fig. 2 is a similar View of the clip, and Fig. 3 is a view in cross-section on the line 3-3 of Fig. 1 with the rail and a portion of the underlying tie added and with a clip in place on the plate.

In the drawing the reference letter A rep resents the head of a rail, B its base, C the web uniting the head and base, and D the tie.

The plate 1 is provided near one side with a shoulder 2 for the rail-base which carries at its upper face a series of integral heavy ribs 3 spaced apart along its length and rising above it and overhanging the top edge of the rail-base when the latter is assembled on a tie-plate. The plate is provided with spike-holes 4 for the spike 5 outside the line of the shoulder 2 and between the ribs 3, and the central rib has a threaded opening to receive a set-screw 6 which bears upon the rail-base to clamp it on the plate. The lower faces of the overhanging ribs 8 are faced off to the contour of the rail-base which makes a driving fit between the ribs and the plate 1.

The opposite side of the plate 1 is provided, with elongated spike-holes 7, and beyond each of these holes and spaced away from its outer end the plate is provided on its upper face with a shoulder 8 having an inwardly inclined inner face 9. The plate is provided on its under face with a recess 10 extending from the inner end of each spikehole 7 toward its center and. of the same width as the spike-hole and terminating in an inner shoulder 11. The spike-holes 7 receive clips that interlock with the rail-base B and tie plate 1 and are heeled up by the shoulders 8 to wedge the opposite side of the rail-base in position under the ribs 3. The clips are made of metal having a substantially rectangular body 12 constructed to overlie a spike-hole 7 and provided at its inner edge with a depending lug 13 to abut against the rail-base and inner end of the spike-hole 7. The inner portion of the body 1 is provided with an upper inwardly di rected flange 14 to overlie the rail-base, and with an inwardly directed lower wing 15 to underlie the inner end of the spike-hole and seat in the recess 10 with its inner end against the shoulder 11. The wing and flange are in the same vertical plane to form a pocket or seat for the edge of the plate and rail-base, the flange being beveled on its under face to fit the inclination of the base, and the lower face of the wing 15 being flush with the lower face of the plate. The lower outer part of the body is thickened transversely and beveled or rounded as at 16 to Wedge against the shoulder 8, and its upper end is provided with an inclined or beveled heeling-lug 17 for the head of the spike 18. The holes 19 for the spikes 18 are outside the depending lugs 13 and have their outerwalls in extension of the lugs 17 In practice, an edge of therail-base is assembled to place under the overhanging ends of the ribs 3, and the clips are assembled on the plate on the opposite side of the raihbase, the wings being passed down through the elongated spike-holes of the plate; the clips are then moved. inwardly toward the rail so that their flanges 14. overlie the rail-base and their wings 15 underlie the inner ends of the spike-holes, and when the spikes 18 are driven to place on the ties they force the clips down on the inclined faces of the shoulders 8 to crowd the clips into place and seat their wings in the recesses in the under faces of the plates and the lugs 17 heel-up the spike-heads so that they are not forced outwardly by the lateral thrusts of the rail and the usual throat-cutting of the spikes is obviated. The flanges and wings of the clips interlock the plates and rail-bases together so that the plates are anchored to the rail, and the clips hold the opposite side of the rail-base in its drive-fit engagement with the overhanging ends of the ribs 3. The clips thus interact with the ribs as they hold the rail under the ribs without putting the side stresses or lateral thrusts of the rail on the spikes, As the screw 6 is set down on the irail base it is advantageous to have spaced or separate overhanging ribs instead of. a single flange extending the width of the plate,; as in the former case. the lifting action of the screw is confined to the central rib and will have no efieot on the end ribs, whereas with a full or single flange this lifting action affects the flange for its entire length and loosens its grip on the rail and the drive fit of the rail base between the flange and plate is relaxed.

I claim:

1. A device of the class described.comprising a plate having an elongated spike-hole in one of its sides and a recess in its under face in line with the inner end of said spikehole, an inclined shoulder adjacent the outer end of said spike-hole an abutment on the opposite side of said plate provided with a plurality of; spaced overhanging ribs, a clip constructed to engage said shoulder and having a spike-hole and an overhanging flange for one side of a rail-base and an inner depending, lug in the inner portion of said plate spil e-liole, aninwardly extending Wing at the lower end ofthe lug constructed to seat in said recess, and a heeling-lug in alinement with the outer end of the clip spike-hole. I p

2. A device ofthe class described comprising a plate having an elongated spike-hole in one of its sides and a. recess in its under face in line with the inner end of said spikehole, an inclined shoulder adjacent the outer end of said spike-hole, an abutment onthe o posite side of said plate provided with a plurality of spaced overhanging ribs, the center rib having'a threaded opening, a setscrew engaging said opening, a clip constructed' to wedge on said shoulder and having a spike-hole and anoverhanging flange for one side of a rail-base, a depending lug in the inner end of the hole in the plate, an inwardly extending wing at the lower end oi the lug underlying the plate and a spikeheeling lug in alineinent with the outer l of said clip spike-hole. g

3. A. device of the class described eoinprising a plate having elongated spikeholes in one oi its sides, inclined shoulders adjacent the-cuter ends of said spike-holes, an abut-- ment on the opposite side oi said plate pro vided with a plurality of spaced overhanging ribs ccnstructed to make a dri ing fit with the side of a raihbase and arranged in staggered relation transversely oi"? the plate with respect to said spike-holes, and clips constructed to wedge on said shoulders and each having a spike-hol an overhanging flange bearing onthe other side of the railbase, a depending lug in the inner end oi the hole in the plate, and an inwardly extending.

wing at the lower end of the-lug interlocking with the plate. 7

i. A device of the class described comprising a plate having an elongated spike-hole in one of its sides an inclined shoulder adjacent the. outer end of said spike-hole, an abutment on the opposite side of said plate provided with a projection overhanging one side of a rail-base and having a threaded openingaa set-screw7 engaging said opening.

a cli" constructed to en 'a 'e said shoulder p z: n

and having a spike-hole and an overhanging flang bearing on the other side ofthe railbase and an inner depending lug in the inner portion of said plate spikehole, and

an inwardly extending wing at the lower.

end of the lug interlocking, with the plate. In testimony whereof I; heretoaffix' my signature.
