TIE-PLATE.

Specilcation of Letters Patent. Patented June 28, 1910,

Application tiled August 26, 1909. Serial No. 514,666.

To all whom 'it 'may concern.:

Be it known that I, WLLLIAM L. Dr. Renan, -a citizen of the United States, residing at Chica-go, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tie-Plates, of which the following is u specification.

My invent-ion relates to tie-plates and the object thereof is to provide a tie-plate having many advantages not only in the matter of manufacture but also in the mat-ter of ef ficieney and reliability in actual use.

Speaking in general terms, my tie-plate comprises a. body portion or plate proper on which the rail rests and a plurality of removable and adjustable portions or blocks which bear against. the opposite sides of the rail flange and are secured to the plate proper by the spikes which hold the rail and tie-plate to the tie. This construction of tie-plate is simple and economical of manufact-ure and has the advantage of being adapted for use in connection with rails of different size as to flange, the only change necessary for the proper adaptation heilig the location of the spike holes in the plate proper and in the adjustable portions or blocks.

In the drawing Figure 1 is a partsection and part elevation of my new forni of tieplate with the rail in section, said tie-plate and rail being shown secured to a tie; Fig. 2 a plan view of the tie-plate proper showing at one end a series of the removable and adjustable blocks, the blocks at the opposite end being removed to show the position of the spike holes; Fig. 3 a. plan view of a portion of such tie-plate proper showing spike holes therein adapting the plate for diii'ercnt sizes of rail; Flg. l a sectional elevation on the line of Fig. 1; Fig. 5 a perspective of one of the adjustable blocks; Fig. 6 a view somewhat similar to Fig. l but Wholly in section and illustrating'a moditied form of tie-plate; Fig. i' a perspective of one of the removable portions or blocks shown in Fig. G; and Figs. 8 and 9 sections showing other modifications.

Referring to the embodiment of my invention as shown in Figs. 1 to 5, my tic-plate comprises a body portion or tie-plate proper marked 1 and a plurality of removable and adjustable blocks 2 which here have interlockin engagement both with the rail and with t e body portion of the tie-plate. To this end said body portion is provided with one or more longitudinal grooves 1 which by preference as herein shown are three in number. rithin these grooves titthe depending port-ions 2 of the blocks 2 with the result that said blocks are movable within said grooves longitudinally of the plate and transversely of the line of rail A.

It will be understood that any desired number of grooves and blocks may be employed and that, even while l have drown three grooves only two of the saine need be utilized for the blocks. l have accordingly illustrated in full lines in Fig. 2 two of the adjustable blocks at one end of the plate orcupying the two outermost grooves, and a third block in dotted lines occupying the middle groove. I have illustrated by dotted lines with respect to the outermost blocks the feature-of the adjustability of the blocks longitudinally of the grooves in order to accommodate rails of different flange widths.

On the other end of the plate l there may be employed a single block in any one of the grooves, or tivo blocks in any tivo thereof, or a block in each one of such grooves. Each of the blocks 2 is provided on Vits upper side with a fiat portion 2" through which the spike hole 2 passes and with an inclined portion Q against which the inclined underside of the head of the spike 3 which is here a screw spike, bears. It will be understood that the plate is pro vided with spike holes 1h which are located aeeordin to the particular width of rail flange with which .it is to cotiperate, the spike holes in the blocks being of course always the same inasmuch as these. blocks are adjustable along thegrooves in order that their spike holes may register with the correu sponding spike holes in the plate proper. By preference though not of neoessity, the tie plate proper may be provided on its underside with a series of flanges l which engage the top surface of the tie 4 and which here are longitudinal of the plate.

As a convenient way for adapting the saine plate to different sizes of rail, such plate may be provided with a series of pairs of spike holes 1E as shown in Fig. 3 to accommodate two diferent standard sizes of rail, and it is obvious that slot-s may be substituted for such pairs of holes.

lVhen the parts of the tie-plate and the rail are in place as shown in Fi". 1 the s ikes as well as the rail itself liold the b ocks in position, the flanged portion 2 of such blocks extending partially under the rail flange and there interlocking there with and the shoulder J of each block form ing tho abutment for a .side of the rail flange as shown in Fig. 1. l

In Figs. (i and i' I have illustrated a modified form of construction of tic-plate in which the body portion or tie-plate proper marked 5 is perfectly flat as to its upper face, that is ungroovcd, and provided with the adjustable and removable portionsor strips 6 resting {lat ucpon said body portion and having an exten inwardi directed underneath the rail flange as clear y shown in F ig. 6. Each strip 6 is provided on its upper face with a {iat portion t3 having spi te holes 6, in the forni of slots, and inclined surface (la, agaii'xst which the inclined underside of the head of the screw spike 'T bears andra shoulder ti against which aside of the ra1l flange abuis. However, this adjustable strip or block dif- Jters from the first described forni in that it extends transversely and all the way across the plate it is obvious that these removable blocks or strips (3 are adjustable to tit properly upon the plate 5 in order to adapt it to the particular rail to which the tie-plate is applied, it being understood that the plate 5 is likewise provided with elongated or slot-like spike holes 5 for said adjustment purposes. This forni of tic-plate` extremely simple and economical of manu facture and the saine is readily adapted for diiterent rail flange widths. the only change necessitated for diilerent rails being the location of the spike holes in the plate 5.

to slide upon each other there-at for adjustment purposes. These portions may or may notbe provided with a so-called abrasion plate but in the present instance I have shown such a plate 9.

As shown in the modification illustrated nient obtained by d iiierent positioning with respect to complementary projections andi notches or grooves in the plate and blocks. To this end the blocks l() have on their under i surfaceaseries of projections and notches which tit' corresponding projections and notches in the plate 11E which by preference ed iianged portion 6a having a longitudine in Fig. 9,A the ad justablc blocks may be iutcrlocked with the plate proper and the adjusti rests upon a bottom plate 12. It will be understood that these projections and notches have a certain relation to the standard rail flange widths so that when the parts of the tie-plate are in the relative position shown they will accommodate a certain iiange width and that. when the blocks are adjusted outwardly the distance of one notch they will accommodate another flange width. This tie-plate like the others may be pro vided with either transverse or longitudinal bottom flanges but in the present instance these anges 12a which are on the bottom plate are of the longitudinal type.

I claim:

1. .t tie-plate comprising a body portion, and a portion adjustable thereon in a longitudinal line toward and away from the rail when in position, said adjustable portion having a spike hole; substantially as described.

2. A tic-plate comprising a body portion, and portions adjustable thereon longitw dinally toward and away from the rail when in position, said adjustable portions being arranged to interlock with the body portion; substantially described.

3. A tie-plate comprising a body portion, and portions adjustable thereon longitudinally toward and away from the rail when in position, said adjustable portions being arranged to interlock with both the body portion and with the rail; substantially as described.

-ls .i tie-plate comprising a body portion having a longitudinal groove, and blocks i'iti ting and movable therein toward and away In Fig. S I have illustrated another modi l'ication wherein the adjustable portions are l reduced at their adjacent ends and arranged from the rail when in position, and having spike openings; substantially as described.

A. tie- )late comprising a body portion having a p uralit-y of longitudinal grooves, and a plurality of blocks fitting therein at opposite ends and having spike openings; substantially as described.

G. A tie-plate com )rising a body portion l groove, and blocks fitF ting and movable therein toward and away from the rail when in position. and having spike awnings` said blocks having inwardly directed flanges extending beneath the rail 105 when in position; substantially as described.
