JOSEPH ID. ELAIG, OEBRQQKLYN, IOWA. V

To all whom it may concern: I

Be it known that I, JOSEPH D. FLAIG, a citizen of the United States, residing at Brooklyn, in the county of'Poweshiek, State of Iowa, have invent-ed certain new and useful Improvements in Ties; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This, invention relates tonew and useful improvements in railway ties and more especially to those constructed of cement or concrete.

The principal object is to provide a concrete tie having a novel reinforcing con struction which is adapted to hold rail supporting plates in position, thus serving the double function of a reinforcing element and a rail securing means.

Another object of the invention is to provide a reinforced concrete tie having rail supporting plates of novel construction for securing the rails'in position, said tie being simple in construction, economical to manufacture and durable in use.

. The invention consists of certain other combinations and arrangements of parts, as will be hereinafter more fully described and clearly specified in the appended claim.

In the drawings :Figure 1 is a top plan view of my improved tie. Fig. 2 is'a side elevation thereof. Fig. 3 is a detailedperspective view of one end of the tie, with the reinforcing elements projecting therefrom,

to more clearly illustrate the same. Fig. 1 is a sectional viewon the line 14 of Fig. 1. Fig. 5 is a vertical sectional view of one end portion of the tie, taken on the line 5--5 of Fig. 2. Fig. 6 is a detailed perspective view of one of the supporting plates for the rails. Fig. 7 is a similar view of a modified form of plate.

Referring to the drawings in detail, there is shown a tie 10 which is constructed of ca ment or concrete and which is provided with Specification of Letters Patent.

provided with inclined and raised projections 14 which are spaced apart toaform transverse recesses 15 for receivingithe sup.- porting plates 16. As is more particularly shown in Figs. 5 and 6 of the drawings, these plates are provided with rail receiving recesses 17 and depending sides 18 which are embedded in the longitudinal sides of. the tie when molded, said depending portions being provided with longitudinal openings 19 for securing the same to the reinforcing elements which retain the plates in position. These reinforcing elements comprise three longitudinal bars 20, 21 and 22 the latter of which is disposed centrally of the length of the tie adjacent its lower surface and the former of which are spaced apart equi-distantly from the upper surface of the tie and disposed through the openings 19 to anchor the plates 16. To hold the longitudinal bars 20, 21 and 22 in proper relation and to further reinforce the tie, a single strandof wire 23 is secured to one end of the bar 21 and is extended at right angles thereto as shown at 24: and looped around the bar 20 as'shown at 25, from which point is directed at an angle toward the opposite end of the tie as shown at 26 and looped around the bar 22 in a similar manner as shown at 25 and then extended upwardly in a similar direction and looped around the bar 21. This is continued throughout the length of the bars and tie and the wire is of such thickness and rigidity to holdthe bars in proper spaced relation when the concrete is molded therearound. 7

In the fastening means employed for the rails 13, it will be seen that the depending portions 18 prevent movement of the securing plates 16 transversely of the tie. and if desired bolts 27 may also be threaded into the plates 16 and tie for securing the rails more positively in position, through the medium of their head portions.

In the modification of the rail securing plates shown in Fig. 7 of the drawings, the recesses 17 for the rails and the securing bolts 27 may be provided in a similar manner but the depending portions 28 have their lower Patented Dec. 112, 1911.

ends bent or turned upwardly as shown at Y 29 to form hooks or apertures for receiving From the foregoing description it will be readily apparent by providing rail securing plates which are retained in position by the reinforcing means or elements such reinforc- 1 ing elements serve the double function. The use of a single strand of wire for holding the longitudinal bars in proper spaced relation, also avoids the necessity of providing any special form of machinery for making the usual shear members employed in reinforcing construction and by reason of attaching the rail supporting plates to the uppermost bars by means of their depending portions, a tie is provided which may be very easily manufactured and which will be durable in use.

I claim A railway tie constructed of molded material, a plurality of reinforcing bars extending longitudinally and embedded in such material, a single wire strand secured at its ends to certain of the bars and looped around the other of said wires to hold the same in proper spaced relation and rail supporting plates seated in the upper surface of the tie, said plates having depending portions embedded in the longitudinal sides of the tie and having openings through which the uppermost bars are secured.

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