Be it known that I, BENJAMIN 'Bn'r'rs,

: a citizen of the United States of America,

and residentof .St. Louis, Missouri, have invented certain new "and" useful Improvements in Tie-Plates, of which the following is a-specification containing afull,vclear, and

exact description, reference being had to the.

accompanying drawings, forming a parthereof.

My invention relatesto improvements-in tie plates, and the object of my invention is to construct a tie plate especially designed for use in connection withrunning rails and guard rails wherein I have provided novel a novel :means for thepl'a'tes. a V v lVith the above. purposes inL-vlew my in vention consists in certain novel features of construction and arrangement of parts as Figure 1 shows in plan a tie plate 'con-' structed according to my inv 'entionf; Fig. 2 is a longitudinal sectional elevation of the plate'taken on the line 2 2'of Fig.3, and' shows in place a running rail anda'guard rail; Fig. 3 is a transverse sectional-elevation of the plate taken on the line 3-3 of Fig. 1; and Fig. 4 is an inverted plan of the plate on a reduced scale.

Referring by numerals to the accompany! ing drawings: 5 designates the body of the plate which has on its upper side extending substantially the width of the plate and adj acent one end thereof a rail-bearing surface 6 for the support of a running rail such as 7.

'On the" upper side 0f the body 5 to one side of and in a plane above the rail-bearing surface 6 is a rail-bearing surface 8 arranged for thesupport of a guard rail such as 9, the i iinner margin of the rail-bearing surface 8 overlapping the inner margin of the railbearing surface 6. By the placing of the one rail-bearing surface in a plane/above the other and with its one. margin overlapping the other rail-bearing surface unaltere standard rails may be employed as a running rail and a guard rail. t

Formed in the side of the body constituting the rail'bearing surface 8 contiguous to the rail-bearing surface 6 is a rail-receiving recess 10, and formed on said body above the recess 10 is a rib 11in which there is a baclg bu't not the fro-n recess 12 contiguous to the rail-bearing surface 8'; each of the said recesses forming continuations of said rail-bearing surfaces. 7

Formed in the rail-bearing surface 8 within said recess 12 is a-channel 13, the function Formed through the body of material having the rail-bearing surface'S'andinterisecting the railbearing shoulder ltare spike holes 15 and surrounding the sides and the is a spike backing 1-6.

Formed. through the sition to the recess 10 is a rail-bearing shoulder 18, and said shoulder 18 is spaced apart from said recess a distance greater than the width of"the*base of V the raill" Formed -through the-bod'yt adjacent-said shoulder 7, 18 are the spike holes 19',"th'e shoulder 1.8-

extending over the backs and sides of said,

openings to act-as spike backings.

ts of ea ch'of said holesg body '5 outside of the body havingthe rail bearing surface 8 is'a spike hole 17. p 7' Arising from the body 5 removed laterally from the r'ail bearing surface'fi and'in oppo- "20 designates a removable plate arrangedf to normally fest against the shoulder"18 and be held in' placeby spikes Which' are driventhrough the openings 19. I w 21designates a brace rising from the rib.

Hand" at an angle so that its uppermost end will engage the underneath face of the ball of the running rail 7 The brace is so formed that its side margin will engage the By preference this web-1 engaging portion of the brace is a web 22,

the lowermost end "of which tinuity of the recess 10. q

Formed. on the underneath face. of the plate are a plurality of ribs 23 extending longitudinally of the plate. 24 designates a rib extending transversely-of the plate adjacent the spike holes 19. These ribsserve as anti-creepers to prevent movement.

of the plate relative to the tie. V I V By. reason of the shoulder l8 being re- 165 ,moved from the recess 10 a distance greater than the width of the running .rail basef it is to be observed that the running rail may be seated in said recess by being moved laterally thereinto. In" order to hold the running'rail fully seated in said recess and to provide a relatively long bearing forthe margin of the rail base opposed to the margin seated in said recess the plate 20 is em ployed which is placed between the rail base and the shoulder 18. Spikes are then driven through the holes 19 and their heads, when fully seated, will overlie the rail base flange,

the ends of the plate 20 and be backed by the portion of the shoulder 18 at the backs and sides-0f the spike holes.

By reason of the channel 13 lying within the recess 12 the guard rail may be removed from its rail-bearing surface even though the rail bearing shoulder 14 is spaced apart from the recess 12 a distance equivalent to the Width of the base of the guard rail, the channel allowing tilting of the entire guard rail to a point where it will be above the shoulder 14*.

The brace 21 is designed primarily to preventbuckling of the body of the plate. Where guard rails are employed there is usually imparted to the guard rail lateral strains or thrusts when rolling stock passes thereover and this brace imparts such strains or thrusts to the ball and web of the running rail, which has suiiicient rigidityv to resist such strains. 7 If it were not for such a brace the side strain imparted to the ball of the guard rail would hear downwardly on the end of the plate and eXert an upward strain on the rib 11 thereby tending.

to buckle the plate. Vfith all of the strain on the rib 11 resisted by the ball of the running rail through the medium of the brace 21 this tendency toward buckling is obviated.

I claim: a

1. A tie plate having a pair of rail-bearing surfaces one of which is arranged in a plane above and overlapping the other, in-

tegral means forming a recess contiguous to each of said surfaces at their overlapped margins, shoulders arising from said surfaces in opposition to said recesses, one of said shoulders being spaced apart from its companion recess a distance equal to the width of arail base, the other shoulder being spaced apart from its companion revwill be overlapped, a rib having a recess therein to receive the base flange of the guard rail, a brace extending from said rib and terminating above and laterally removed from the rib to engage beneath the ball of a running rail, a rail bearing shoulder on each surface, and a channel in one of said surfaces opposite the shoulder, and there being spike openings through each surface neXt adjacent said shoulders.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
