WARREN G. PATTERSON, OF TAMAQUA, PENNSYLVANIA.

METALLIC RAILWAY-TIE.

To all whom it may concern:

Be it known that I, WARREN G. PATTER- soN, a citizen of the United States, residing at Tamaqua, in the county of Schuylkill and State of Pennsylvania, have invented a new and useful Metallic Railway-Tie, of which the following is a specification.

This invention relates to railway ties, and particularly to metallic railway ties.

An object of the invention is to provide a railway tie with downwardly projecting parts for penetrating the earth and preventing any lateral or longitudinal shifting of the rails.

A further object is to provide the tie with means whereby the rails may be spiked down in the usual manner by the use of ordinary spikes, thus obviating the necessity for using special-bolts or other fastening devices and rendering the railway tie of the present invention strong in its construction, reliable, durable and economical in installation and maintenance.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description,

taken in connection with the accompanying drawing'forming a part of this specification; it being understood that while the drawing shows a practical form of the invention, the latter is not to be confined to strict conformity therewith, but may be changed or modified, so long as such changes or modifications mark no material departure from the salient features of the invention as specifically pointed out in the claims appended hereto.

In the drawing, in which similar reference characters designate corresponding parts throughout the several figures.

Fig. 9 is a plan view of a tie of still a different form of consti uction, one end being shown in horizontal section.

One of the principal items in the maintenance of railways is the cost of the ties which, if formed of wood, are constantly requiring replacement by reason of their quickly rotting out, and in the event of their being formed of cement or concrete are so expensive to manufacture as to render their use almost prohibitive. The device of the present invention has been designed with a view to providing a tie having all the advantages of the wooden or the concrete tie and eliminating the disadvantages of the same by the provision of a practically inclestrnctible metallic tie having means for engaging the earth to prevent any movements of the same in any direction, while under strain, and also means whereby the rails may be readily spiked into position in the ordinary manner; and a tie wherein the number of parts is reduced to a minimum; and wherein a plain, smooth surface is presented to the action of the elements and all pockets or crevices which catch and hold water, are eliminated.

The tie consists of a sheet of suitable iron or steel or some other specially prepared metal and bent to form a top and side flanges 22, formed integrally therewith and extending substantially at right angles thereto along the longitudinal edges thereof. The channel metal comprising the tie is of suificient strength and thickness to withstand the enormous strain to which railway ties are subjected and may be readily found in stock material as manufactured. The proportions of the tie as to length and width, may be varied to suit the particular road on which they are to be used, it being of course understood that at switches, crossovers, and the like, the length of the tie will have to be increased.

The top 1 of the tie is provided with a pair of spaced openings 33, preferably, though not necessarily, rectangular in form, and the centers of these openings 33 are a distance apart equal to the distance between the centers of the rails of a standard gage road.

Metallic boxes 44, formed of the same material as the tie preferably, are secured to the underside of tie, between the (161 pending flanges 2-2 and in surrounding relation to the openings 3-3. These boxes are open at their tops and comprlse, each,

a bottom 0, side walls 6-6 and end walls 7-7, defining a receptacle having dimen- -sions equal to the dimensions of the openings 33 in the top plate of the tie.

The side walls 6-6'of the boxes are provided with integral outstanding flanges 88, extending toward the depending flanges 33 of the tie 1, and provided with suitableapertures in registering relations with suitable apertures formed in the top plate 1 adjacent to the corners of the openings 33 therein. Rivets or bolts 9, or

other suitable fastening devices traversing the said registering apertures of the top plate and the box flanges serve to securely hold the boxes in position upon the under side of the tie, and it will be noted that the depth of the boxes is equal substantially to twice that of the depending flanges of the tie-and form decided projections which are adapted to enter the earth a substantial distance beyond the-marginal flanges 22.

Wooden blocks 9 9- are cut to snugly fit the boxes H and to rest therein, the top surfaces of the same lying flush with the top surfaces of thesaid ties, and the rails interfere with the flanges of the said rails.

.In Figs. 5, 6 and 7, there is illustrated a slightly modified form of the invention wherein the large openings 3-3 are eliminated and a pair of spaced rectangular openings 3 are employed for the passage of the spikes 11. These openings are preferably of a size to admit the shank of the spike and to exclude water from the wooden block 9 contained within the box 4: in the same manner as the previously described form of the oinventiomand the said openings 3 are arranged in different longitudinal lines with relation to the tie, so as to avoid sphttmg the wooden block 9 when the spikes are driven home.

In Fig. 8 an arrangement is shown wherev in a pair'of spiked openings 3 are provided to lie at each side of a ra1l and in position-to securely hold the latter to the tie 1.

V In place of the wooden blocks located 'within the boxes l4, concrete or cement =;iblocks ,9 may be used, as shown in Fig. 9,

into the boxes in a plastic condition, and headed bolts.11 placed in position during the process having their upper threaded ends extending through suitable apertures in the tie 1, and beyond the top surface of the same the proper distance apart to receive the flanges of the rails, as will be understood. Suitable nuts may then be screwed upon the threaded upper ends of the bolts and clamped down upon the said rail flanges to securely bind the rail in position upon the tie.

The concrete filler 9 may be used with either form of the invention, as the same may be readily poured into the box e of the form shown in Figs. 14, through the openings 3-3 and allowed to harden with the aforementioned headed bolts in position, whereas, in the case of the forms shown in Figs. 5 to 9 inclusive the concrete filler 9 is formed in the box 4: before the same is secured in position upon the under side of the tie 1 by means of the rivets 9.

From the foregoing it will be seen that an extremely simple, durable and .cheaply manufactured railway tie has been provided which may be handled and installed in the same manner as the ordinary wooden tie, and which, by reason of its composition, will not sag,,r0t or warp, and, having means for penetrating the earth, may not slue or creep while under the pressure of passing trains, the side flanges of the tie effectually preventing any movement of the latter in the direction of the line of travel and the depending boxes likewise holding the tie immovable in a transverse direction.

hat is claimed is 1. A metallic railway tie, comprising a top plate having integral, marginal flanges depending from its longitudinal edges and having openings formed therein adjacent to its ends, and open-top boxes secured beneath the openings upon the underside of the tie and comprising bottoms, end walls and side walls carrying outwardly extending flanges for attachment to the tie between the flanges thereof, said boxes being of greater depth than said flanges.

2. A railway tie comprising a metallic base member having integral, depending iarginal flanges along its long side edges, said base member having openings adjacent to its ends and spaced apart a distance equal to the distance between the rails, metallic boxes secured to the underside. of the base member between the depending. flanges thereof, and below said openings. said boxes being of greater depth than said flanges, and blocks fitted within the said boxes and constituting a foundation for the spikes,

3. A metallic railway tie, comprising a top plate having longitudinal marginal flanges formed integrally therewith and having spaced openings formed therein adjacent to its ends, metallic boxes corresponding to the shape of the said openings and adapted to be carried upon the underside of the tie, said boxes comprising bottoms, end Walls and side Walls, the side Walls carrying integral outstanding flanges extending toward the depending flanges of the top plate, means for securing the out standing flanges thereto, and blocks fitted Within the said boxes and adapted to lie with their upper surfaces flush with the upper surface of the tie so as to support the rail and to receive the fastening means for holding the same, said boxes extending down below the side flanges of the tie and adapted to penetrate ,the earth for preventing movement of the tie thereon.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
