Be it knownv that I, Jrsssn' F. A. An'n'r, a citizen of the United States. residing at? Cambridgeiin the county of Guernsey and State of Ohio; have invented certain new and useful Improvements in Reinforced, Concrete Railway-Ties; and I do declare description of the invention, such as will. enable others skilled-in "the art to which it appertains to make and use the-same.

This application is a division ofmy. prior application Serial No..623,(369, filed April 27 1911 and the present invention relates to railway ties and has for its object to provide an improved reinforced concrete railway tie; -W'ith thi object in view, the invention consists in' the improved c'onstruction ar-j rangement. and combination of parts-of a? tie of thischara'cter which will beherein-' cally claimed.

In order that the construction and operation of, my invention may be readily compre: hended, I have illustrated a preferred emdrawings in, which-:

Figure '1 represents a' perspective view of my improved tie, arts being broken out to show the reinforc n or bonding: rods and carrier in position; ig. 2 represents a top plan view of the tie'on a somewhat reduced scale; Fig. 3 represents a sectional view through the reinforcing rods in. operative position showing the bond-carrier in elevatioii, also. in operative position upon the rods; Fig. 4 represents anedge elevation the parts shown in Fig.3; Fig. 5 represents. a top plan view oi? the-parts shown in Fig. 3. Like reference characters markthe same parts in all the figures of the drawings.

Referring specificall to the'drawings, my improved tie, indicate at 10, is composed of any well known concrete or like mixture reinforced by a number of, preferably four,

ably locatedlongitudinally in-t-hetie in p0.-

of my improved bond-carrier 15,, the position of the reinforcing rod and bond-carrier-in the tie being clearly. illustrated in Figs. 1 and 3 especially. I

The/bond-carrier 15,.when ready fior' use,

in the mold, comprises a. base-bar 1.6-,'top

bar 17, loops 18;, 19,-120, 2.1;, forembracing respectively, the reinforcing rods 11,12, 13 and 14, and upright bars 22 and 23 connecting. respectively, loops 18 and 20 and 19- and 21, the position. of the'inn'er portion of-the mater al forming the several loops and the uprights 22 and 23 when. placed inposition to receive the reinforcing'bars. being in'a single. orthe same plane witliithe loops turnedinward 'fromflthe ends of the cross barsand the upright'bars' centrally located and side by side. as indicated'in dotted lines in Fig. 3. themain portioniof the loops with.

the base-bar 16 and top' har '17-. and'the up right bars-22 and 23 in their final-position,

being indicated in fulllinesinthat figure. \Vith the Dartsoffthe bond-carrier 'inj the positions described; the rigidity of the reinforcingrods 11; 12 13."ai1d 14' would depend upon the fitof the'loops'upon the bars. butthis might be somewhatunreliable; and

in order to avoidthis nncertaintv. afterthe carriers have been placed inpositiori on the .rods with the parts'in the dotted line position of Fig. 31 1 bend the inner portionsiof the metal which-forms the loops inwardly, out of the plane inqvhichthese partsare first located into the positions indicated in Figs.-

1, 4. and 5 andin full lines in Fig; 3: In

this positionthe metal forming the loops" is much more closely entwined and more .rigidly held around the reinforcing rods 11.12, 13, and 14. and the upper ends of the vertical bars 22 and 23 are brought into position to utilizethem foranother purposelater de scribed.

With the reinforcing rods and the' hondcarrier in position.- as described and as shown in Fig. 1,1 will have provided 9. thoroughly strengthened tie, and in order-- to afford means forthe proper reception f the rail plate and rail upon the tie and t e proper securing of the same thereon. I have provided' transverse notched seats 24 and 25 inthe 'top of the tie. and the location of these seats relative to the reinforcing rods and bond-carriers is such that the uppcrmost points of the reinforcingrods; as at 26 will be flush with .the surfaceof thctie in the seating notches 24 and .25 and the upper ends 28 of the upright-bars 22' and 23 of the bond carrier willibe flush with the same sur ce. 1

The up ercrosg 1 7 of the bondcar rier is flush with the upper surface of the tie itself and will form the outer wall of each of the notchedrail seats 24 and 25, thus affording a much greater resistance to lateral outward spread of the rails secured in said notched seats. In order to accommodate these upper cross bars 17 'of the bondcarrier, the outer wall of each notched seat is recessed at 29, as clearly shown in Figs.

11' and 2, so as to bring the metal of the upper bars 17 into direct contact with the outer edge of the base of'the'rail plate to prevent the crumbling or gradual wearing away of the outer walls of the notched seats.

'The bottom of the rail plate will thus be seated directly upon the upper surface of the longitudinal reinforcing rods 11, 12, 13, and 14, and upon the upper ends of the bars 22 and 23 of ,the-bond-carriers, which will also prevent to a very large extent, the wearing away of the surface of the concrete tie.

The utility and superiority of my im provedtie as just described will be obvious and it will be clearly evident to thoseskilled in the art that the uality of the mixture of which the tie is ma e, the size and material of the various-metal parts used, and their relative shapes and locations, may be considerably. varied without departing from the spirit and scope of the invention.

I claim as my invention 1. A bond-carrier fora molded railway I tie comprising transverse upper and lower cross bars, loops at the outer ends of each of said cross bars turned inwardly toward the center-thereof, and parallel upright bars connecting the inner ends of the 100 s of the respective cross bars, the upright ars be- -ing.centrally located with'relation to the cr ss -harS and all of the parts being in a single pnne.;;;:;;- v 2. A moldedrailway tie having reinforc ing elements comprising bond-carriers, each consisting of parallel upright bars and out- 4 wardl extended loops at each end of each bar, t e upper loops being connected by an upper cross-bar and the lower loops by a lower cross bar, and longitudinal reinforcing rods secured in-the loops by forcing the upright bars out of the plane of the base and top bars, and thus closing the loops very effectually about the longitudinal-bars.

3. A molded railway tie provided with transverse notched rail seats, longitudinal reinforcing rods embedded in the tie flush with the bearing surface of said seat, and bond-carriers embracing said rods having upright bars, the upper ends of which are also flush with the bearing surface of said seats. v

- 4.. A molded railway tie provided with transverse notched rail seats, longitudinal reinforcing rods embedded in the tie flush with the bearing surface of said seats, bondcarriers embracing said rods and having top bars projecting above the longitudinal rods and forming outer walls for the rail seats.

5. A molded railway tie provided with transverse notched rail seats, longitudinal reinforcing rods embedded in the tie flush with the bearing surface of said seats, and

bond-carriers embracing said rods having- JEssE F. A. AULT. Witnesses F. S. MOOREHEAD, F. B. AMos.
