$1929.y Serial This isa division ofj'my application Serial No. 352,953 iiledApril 6, 1929, vfor Letters Patent ofthe UnitedStates Afor improvement in metallic railway ties. Altho my fastening device maybe advantageously used with such metallic ties as described in the originaliv application it may also be used withA other ties formed :of metal o rY other material" such as wood orlconcrete. Y y v Y As hereinafter described;`A my invention l includes a rail chair plate, which may beweld-V ed in integralrelation with theupper `surface of a metallic tie, or be used'separately in connection withja tie formed of any material. Saidl plate includes means foradjustably rigidly securing a rail in properspaced relation thereon and in electrically insulated relation therewith.y 'Such chair plates are adaptedto cooperate with lever clamp blocks which are respectivelyffulcrumed upon the 'outer upper edges of the endsof said plates;` said'plates having screw sockets extending vertically therein localto each clampblock and adapted toireceive cap screws for pressing vthe clamp v blocks kdownwardly'-upon the rail flanges.

Said plates also have screw-sockets extending horizontally in the ends thereof adaptedto 'receive cap screws which'bear upon the' outer ends ofthe respective clamp blocks; whereby said vblocks may beg-adjusted transversely to the rails, to properly space the latter.

My improvedrail'clamping'means also'in'- clude a locking plate wherebyboth of thecap -screws local to each block may be prevented from rotatingfroni the position tovwhich they areA adjusted, but. which'may be readily released.l to permit said screws to be otherwise adjusted. Y

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

connectit with a tie l*and having ca lks adapted to be imbedded insuch a tie. l r Referring tov the formv of myd inventiony shown inFigs. Ito III inclusive 5 the tiel may v i be formed of metal rigidly connected vat lits top surface withthe rail chair plate 2, convensuch connection' might be made byany suit'- able rivetor screw means. Each of said chair plates 2 has, at opposite ends thereof, similar fulcrum ribs 4. 'Each such plate2 also has two screw sockets GeXtendingvertically thereA in respectively near'the opposite endsv thereof, and two screw sockets 7 extending 'hori- `Zcntally therein at the :opposite ends thereof; :all ofsaid screw sockets being conveniently However, of course,l i

intermediate of the widthi'of the plates, as f.

I prefer to providethe-screw sockets 6 with conical rims 8 at lthe upper ends thereof to shed water outwardly from the 'threads :of the screws 10 which are` fitted therein.

Each of said chair plates 2 is-provided with a pair offlever clamp blocks 12 which are fulcrumed. upon said ribs t'and. adapted toY be.

rdrawndownwardly bysaid screws 10 which extend thru slots 13 in the respective blocks.` Said blocks 12 have Vbifurcated outer end bifurcations, respective set screws 1 6 which and are adapted to adjust saidA blocks 12 21 nearftheir inner ends which depend in opposition to` the-side edges of the rail flanges 18 and determine the position of said rails.

VIn order to electrically y insulate said rails 2:() frorncsaid chair plates 2; I prefer to .pro- .vide each such plate with a pad of linsulating material 22.r Each offsaid blocks 12 is also electrically insulated fromthe adjoining rail flange 18 by an angular ad of insulatingmaterial 24, interposed as s iown in Fig. I.

In'order to prevent accidental displacement provide them with locking plates 26,'eacliofV Vwhich has an opening 27 fitted to'tthe headk of thelo'cal cap screwv 10, and a notch, 281 fitted Aflanges 14 adaptedtofrecei-ve, between their A Si).V extend in said screwsoeketsZV in the plates 2 Y 'Y to the head of the local set screw 16; each of said plates 26 is normally in the shape shown Y in full lines in Figs. II and III; in which may be bent in wardly, as indicated in dottedlines in Fig. III, toprevent the respective.

locking plates from bein@l accidentally dislodged upwardly thus preventing rotation of both screws. However, said plates 26 are madefofmetahpreferably mild annealed steel,

in full lines in.. said ligure, to permit the rel plate having vchair plates integrally fixed so far flexible that said prongs 30 may be rebent outwardly from the position indicated in dotted lines in Fig. III to the position shown moval of the `lock plates 26 thus released, and permit further adjustment of said screws 10 and 16, whenv necessary, or if it is desired to remove the'local clamp block 12 or rail 20.

Referring to Fig. IV; rail chair plates 32,v

otherwise resembling said chair plates 2, may have a'plurality of holes 33 `extending therethru,v for screws to engage them with ties,

Vand have a plurality of calks and 36, projecting downwardly therefrom, in transverse relationwith each other, and adapted to be` imbedded in the tie to which the plate is connected; so as to prevent accidental lateral displacement of such plates 32. j It 'is tfo beunderstood that-such plates 32 may be equipped with clamp vblocks 12 secured by screws 10 andv Y16, as above described.

t may be observed thatthe form of my invention shown Vin Fig. IV is adapted for rigid connection with a wooden tie;,said

calks 35 and 36`being sharp at their lower edges so that theymay be caused to imbed themselvesin such a tie under pressure of lag i screws lextending thru the holes 33. `Of course, other lockingmeans may be employed in lieu ofthe plates 26. i

Therefore, I do not desire to limit myself to the precise detailsof construction andarrangementherein'set forth, as it is obvious that various Vmodifications may be made therein without departing from the essential features of'my invention, as defined in Vthe 5o appended claims.

I claim: y f 1. A metallic Vrailway tie, including a top thereon; each of said chair plates .having fulcrum" ribs at, respectively opposite ends tliereof;.rail lever clamp lblocks mounted on said fulcrum ribsg and screws respectively engagingsaid chair platesy and adapted to adjust the position of said blocksftowardV saidplatesto'clamp rails thereon. y v l "2.' A tie structure as in claim 1, including screws extending in said chair plates longigitudinally in said plate at the opposite ends thereof, adapted to receive rail clamping screwsin transverse relation to each other. 5. A structure as in claim 4, having fulcruinelements at respectively opposite ends thereof between said screw sockets ,fand lever clampA members Vadapted to rock on said fulcrum members,`and adjustable vertically and longitudinally with respect to the tie by said screws.` Y,

6. Rail clamping means accessory to a railway tie, including a clamp block; adjusting screws extending in transverse relation'to each other in cooperative relation with said block; and locking `means for said screws, including a plate having polygonal openings fitting the heads of said screws, at the oppo- 'site ends of saidl plate; said ends being in detachably engage said plate and to Vrelease l the same with respect to said screws.

8. "A metallic railway tie chair plate having fulcrum members atv opposite ends thereof; lever clamp blocks mounted on said fulcrum members; a pad of electrical insulating material supported by said vplate 'intermediate of said clampblocks;.and electrical insulating members4 respectively engaged by the inner ends of said'v clamp blocks and adapted to fit the opposite edges of rail base flanges resting on said pad; and screw means connecting said blocks and plate; whereby a Vrail may be rigidly clamped upon said plate in electrically insulated relation therewith.

In testimony whereof, VVI have hereunto signed kmy name at Philadelphia, Pennsylvania, this sixteenth day of August, 1929. RAYMQNDL. VARE.
