CROSS-TIE FOR RAILWAYS.

sPECIFICATION forming part of Letters Patent No. 742,144, dated October 27, 1903. Application filed February 28,1903. Serial No. 145,541. (Ndmbdel-J To all whom it may concern.-

Be it known that 1, DAVID S. AFFLEOK, a citizen of the United States, residing at Ohesterton, in the county of Porter and State of Indiana, have invented certain new and useful Improvements in Cross-Ties for Railways; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to cross-tie construction; and it consists of certain novel features of combination 'andconstruction of elements, as will be hereinafter clearly set forth in the specification and pointed out in the claim.

The object of my invention is to provide a cross-tie of some suitable plasticmaterial which after being set or hardened, either by means of the natural cohesion of parts or by burning, as when clay is used, will form a cross-tie of great rigidity and strength, my prime object being to provide means for re inforcing the plastic material employed in forming the body of the tie, as by means of a metallic framework, which will be entirely covered by the plastic material, and thus be protected against corrosion and consequent destruction.

Further objects and ad vantages will be hereinafter clearly pointed out, reference being had to the accompanying drawings,which are made a part of this application, and in which- Figure 1 shows a perspective view of my improved cross tie complete. Fig. 2 is a transverse section of the tie on a line with a pair of the vertically-disposed rail-securing bolts or members. Fig. 3 is a similar View to that presented in Fig. 2, showingaslightlymodified construction of certain parts. Fig. 4 is a similar View to that presented in Fig. 2, excepting that the rail-securing bolts are held against spreading by means of a simple bar or plate; and Fig. 5 is a perspective view of one of the nut-retaining plates.

I desire to state in this connection that while my invention is designed for the production of a cross-tie for railways which will be found to be very reliable and efficient the same reinforcing means herein illustrated will 'be'fonnd desirable and useful in forming fence-posts from plastic material, it being obvious that the metallic reinforcement here- 'inafter described will impart great strength way-tie formed of clay, afterward properlyburned or of cement or slag or other suitable material having a-reinforcing metallic framesection, which 'in this instance consists in locating, preferably in thecentral part of the tie-body, two parallel rods or bars 2 "and 3. The longitudinally-disposed bars2 and 3 may be left entirely straight, though I prefer to provide in each of them a plurality of short bonds or curves, whereby the bars will be corrugated throughout their entire length, and thus present a greater-amount of surface to the material of the-tie and also more securely anchor themin place.

In order that the reinforcing- bars 2 and 3 may be located at a proper point in the body of the ties El and also that said ties may be provided with means to lock the trackrails in engagement therewith, I locate near each end of the tieat a proper point on the track-rails two pairs of rail locking verticallydisposed bolts 4, the upper ends of which are preferably threaded to receive the rail-locking nuts 5, which are designed to be turned securely home upon the rail-engaging plates 6, whereby both the inner and outer edges of the base of the rail will be engaged. The bolts 4 are of sufficient length to extend entirely through the tie and are also threaded at their lower ends and carry the nuts 7, which may be located at any desired point, said nuts being adapted to support the plate, which is preferably angular in cross-section, as indicated by the numeral 8, suitable apertures being provided in said plate to receive the bolts 4, as shown in Fig.

The object in providing the angular plate 8 is to insure that the nuts 7 will-be held against rotation after the same have been adjusted in their desired position.

The plate 8 is intended to support the rods 2 and 3, and since the lower ends of the bolts 4 are adapted to rest upon the bottom of the ICG box or mold in which the plastic material forming the body of the tie is disposed it is obvious that such material when forced to the bottom of the mold or box will entirely surround the bolts 4, the plate 8, and the rods or bars 2 and 3, thus enabling said rods or bars to be supported at the desired height during the formative period of the tie-body.

In some instances I prefer to slightly extend the ends of the plate 8 and curve the same upward, as indicated by the numeral 10 in Fig. 3, thus providing means for holding the rods or bars 2 and 3 from casually slipping out of place while the tie is yet in plastic form.

In some instances a simple plate 11 may be employed to provide a support for the rods or bars 2 and 3, as shown in Fig. 4:. It will thus be seen that reliably efficient means are provided not only for reinforcing and strengthening the body of the tie, but also for locking the track-rail to the tie at the desired point thereon, such locking means being of very reliable and efficient character, inasmuch as the nuts 5 may be very securely locked against the plates 6, as the lockingbolts are very reliably held in position by means of the transversely-disposed plate embedded in the tie. The said plate 8 not only subserves the purpose of holding the bars or rods 2 and 3 while the body of the tie is yet in a plastic condition, but also reliably anchors the locking-bolts a in place, whereby they perform their office of holding the trackrail in an adjusted position on the tie.

While I have described the preferred construction and combination of parts deemed necessary in carrying out my invention, I Wish to comprehend such substantial equivalents and substitutes as may be considered as falling fairly within the scope and purview of my invention.

What I claim as new, and desire to secure by Letters Patent, is-

The herein-described cross-tie comprising a body portion formed of plastic material and hardened and suitable reinforcing means for said body comprising the longitudinally-disposed bars 2 and 3; rail-engaging bolts 4 arranged in pairs at each end; an choring-plates for said bolts designed to afford a seat for said bars While the body of the tie is being formed, said bolts being adapted to extend entirely'to the bottom of the tie whereby the bars 2 and 3 will be held at the desired point, all combined substantially as specified and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID S. AFFLEOK.
