This invention relates to concrete :railroad ties, andhas for one ofits objects to provide a tie of this character embodying novel reinforcing means which shall be adapted to prevent the tie from cracking, breaking or crushing under any shocks, Jars or loads to which'it may be subjected by 'a passingcary or train.l
The invention has fora further objecttoy s provide a tie of thecharacter stated which shall embody rail plates recessed in the' upper surfaces of the end portions of the tie fand havinganchors embeddedin the tie-in such manner as to firmly hold the plates in .1 place.
The invention has for a further object to provide a tie of the character stated wherein the rail pla-tes shall have serrated portions for engagement by serrated portions of rail clamps secured to the plates by bolts, the engagement between the plates and clamps preventing the clamps and consequently the rails" from having any inward or outward move- Inent with respect to the tie.
The invention has for a further object to provide a tie of the character stated wherein the rail plates shall be provided in the serrated portions thereoffwith keyhole slotsfor the reception of the bolts, the formation of the slots permitting theboltst'o' be readily n applied to the plate after the application of the plateV to the tie and also permitting the quires. f l
The invention has for afurther object to provide a tie of the character'stated wherein the reinforcing means shall have portions thereof locateddirectly below the rail plates, and wherein such portions shall` be spaced downwardly from the rail plates sufficiently to arrange substantial portions ofthe vtie therebetween, such tie portions insulating the rail plates from the reinforcing means and thus preventing the short circuiting of opposf ing rails, and such tie portionspermitting the formation in the ties of recesses located below the rail plates for the reception of the heads of the bolts and to carry olf any water passing through the bolt receiving lslots of the rail plates.'y
With the foregoing-and I'other `view, the nature-'ofwhich will, appeara the description proceeds, the invention consists in the construction,*combination and arrangev ment of parts hereinafter fullydescribedand claimed, and illustrated in the vaccompanying partly in horizontal sectionV of a concreterailroad tie embodying my' invention,

The reinforcing bar 2 comprises 'a central portion 2a and end portions 2b, the .cen-
ltral portion being, greater in heightffthank the end portions and located between the rail plates 3, and the end portions being 4located belowgand spaced fr oumjthe railplates. The;
