' To all/whom.'- 'itnnay conce-rn the following Beit known' that I, Santoni-Gomis Joni', a'fcitizen of the United Statesfresiding 'at Dubuque, county of Dubuque-State oillow'a have invented a eertainnewffand 'useful Im# prot-'ement -in Railway Tracks, and declare to be a t'ull,` c1ear,- and 'exact description olf the same, such as will enable` others skilled 'rntheart to whichr it pertains to make and use 'the -samev reference being .had tov the accompanying drawings,- which form Aa part of this speciication.I v t switching points in"iailway tracks, particularly the point where Athe l-ii-og as located, diiculty has always been experienced in maintaining the properl augey between the various elements', eectivey securing the rails and guardv rails, fand' preventing looseness in and creeping of the v:fi-og.

The object of the present invention iste producev a 4simple-and' novel construction which will ermit the Wheel-supporting or wheellengaging members of a track, paiticularly at -a switchingpoint, lto be accurately located and Vfirmly fixed in therst-inof timeand without. requiring const-ant sueivision andv adjustment.

r he variousfeatures of novelty whereby' m. invention is characterized will hereinafter be minted-out wit-li paiticulajrityin the claims llmt, for a full understanding-of invention 4and of l'its object and ,-advantages, reference maybe had totheffolloiving `detailed description taken in connection with the accompanying drawings,v wherein:

Figure '1 -is a pla-n view of fa section 'of -a railwayT track where the `frog 4occurs at a switching point;

Fig- 2 is a sect-ion on a somewhat larger scale.l taken approximately 4ontlie line 2i-2 of Fig. 1,' all of the parts except the rail elements 4and the rail braces being'- shown in elevation; -Q

Figsj, L and 5 are plan views, on a. still larger scale, vofthe three sections into which one of the tie plates is divided;

Fig.V G is a longitudinal section, on an enlarged scale, through the joint of two of the tie plate sections, shown ras insulated -from cach other;

Fig. 7 Sis an 4edge view-of the adjoining ends of tit-'o sections ofthe tie plate having associated therewith an adjusting spacer;

.'l'iig.l 8 is a perspective view-of the-spacer employed in the construction shown in Fi 7. Y i v eferri'ng first. to Fig-'1, -1 represents the continuous rai-l in the main track 2 and 3 the'continuous rail in' the'tuin-out track. v A guard rail 4 isv placed ofn the inner side of the rail 1 and-aguard rail 5 is placed 'on the innersdeof thefiai'l 3. Thesetrack elements overlie long railroad ties V6 extend# ing' 'continuously the usual manner. In accordance vwith my invention Ijrplace enst-least one otlieties,4 and preferably on three of them, a' Vtie plate extending continuously underneath' the lrails and the frog; these'te plates Vbeing indicated in'Fig ll-'at A, B and C. Each tie plate vis 'provided with =inte0fral shoulders projecting' a short distance anore the'same and across the entire width thereof at the following pointszpat 7 in position lto abut against.- theouter edge ofjthe base of the rail 1; atS in position to'abut' againstthe inner edge of the :base of the" guard rail 4; at 9 land 10 vimpositions' toabut against the the frog,4

underneath the saine in base ofthe frog at opposite slidesfthere'o; -at

l1 in position 'tio' abut.' favaiixstthe inner' side of the base of theguar-draili 5; and at 12in rably placed on the -innr sides -o fthe the ties. Spikes `rua-y also, b e 'drivenf through the tie plates between each rail and its guard vrail.4 The rail braces may be' fastened in p'laceby means of' s iltes* or screws 18 passing through the tie plate. Each tie plate may b e spiked Ior the underlying tie at intermediate points-as indicated at 19. lfdesired, each tie plate maybe 4made in a plurality 'ofsections arranged end to end and fastened togethere thereby permitting the two rails of a track to be insulated from each other and providing Ymeans for adjustment. `In the arrange` ment shown, each tie plate is made in three sections bolted together by means of holt-,s 420.

screwed' to section 22 serve The tie plates lare made sufficiently heavy so that they will serve as :efficient struts to transmit a lateral thrust from one track element, the guard rail 4, for example, directly through the tie plate and its shoulders to the other track elements lying in the direction ot' such thrust. Thestress'es starting at any one point will therefore be dis tributed throughout the entire struc-ture and, as long as .the various track elements lie in Contact with the shoulders on the tie plates, there is no opportunity riven for a shifting of the elements I elatively to each other so as to produce a 4change in the gauge.V l"urt-hermore, -since .the fro r decreases in width from the right han( end, as vie-wed in Fig. to the left hand end, and since the shoulders 9 andv 10 are shaped to lie parallel with the surfaces of the frog with which they engage, the frog maylbe said to rest in a tapered seat which will positively prevent creeping from the right toward the .left as viewed in F ig. l. 'llhe tie plates therefore serve asefiicient antim-eepers to prevent the frog from traveling lengthwise iu the direction whichl would cause harm. The tie A)lates of course 'prolect the ties which,4 at. t 1e point inthe track under consideration, ordinarily wear out very rapidly. A l.

In Figs. 3, 4 and 5 I haveillustrated the three sections of one of thetie' plates, the section 21 being the one :lying underneath the main rail 1, the section 22 laying beneath the frog, and the section 23 lyin .beneath thel rail 3', as viewed in Fig. l. 'Ille square holes in the plates in Figs. 3, 4 and' 5 represent spike holes while theround holes and the elongated'slots are forthe purpose of receivinU-the 'bolts for fasteuingthe sec` tions toget 1er., The middlesection 22wmay be llat exce t thatit has the raised shoulders 9and 10 w iile each of the sections2l and 23' has one end pressed upwardly through a height at least equal -to the-thickness lof the middle section, as indica-ted at 24 and 25 respectively.. The part 24 is adapted to over-V lie 'the left lia-nd end Vof the section 22 and the part 25 is adapted to overlie the right hand end of .the section 22. Bolts passing through the holes 26 in the part 24 and the slots 2T in the part 22 and .through the holes 2S in the section 23 and the s1ots'29 in the to fasten the' severa-l sections together. If desired, a layer of insulating material. as indicated at 30 in Fig. 6 may be placed between the overlapping portions of two adj acent'sections, sleeves or bushings of insulating material 31 being placed in the bolt holes.

If it be desired to provide means for adjusting the length of the plate, without leaving a gap between the edge of one section and the facing edgel of the'other seclimil Z-shaped plates, one of which is shown at 32 in Fi s. 7 and 8, ma Y be provided, each of these p ates having s ots 33A adapted to register with the slots in the section 22 and having at the ends flange-s 34 and 35 turned in. opposite directions; the flange 35 being thicker than the Harige 34. This plate may be placed between the overlappinr ends of two sections as shown in F ig. 7. Vhen the flange 35 is turned u wardly, the flange 34 is arranged between tie facing ends or edges of the two sections and serves to transmit the thrust frombne to the other. If it be desiredy to. incr'ea the effective length ofthe tie plate, .the plate -32 can be reversed so as' f to bring the flange 35 in the position occupied by the flange 34 in Fig. and, since the flange 35 is thicker than the flange 34, the effective length of the tie plate will be increased while maintainin continuity of metal throughout the lengt thus avoiding the necessity of placing reliance on theV grip ofi the bolts between the sections in v'order to trans-mita. thrust past a joint in the tie plate.

I claim-z l. The combination with the main rails, guardrails and turn-out rails and the frog of a railway track at a switching point, of tie plates extending continuously underneath 4and transi-ersely of the Same; each .tie plate having' thereon. ii'itegral shoulders abutting against the outer side of eachof said rails, against the inner sides of the guard rails, and ou each side of the frog.
