RAILWAY-TIE.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed March 23, 1905. Serial No. 251,631.

To all whom it may concern.-

Be it known that 1, WILLIAM I. F. HARDEN, a citizen of the United States, residing at Hartford, in the county of Lyon and State of Kansas, have invented certain new and useful Improvements in Railway-Ties; 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.

My invention relates to improvements in railway ties and means of securing rails thereto.

It has for its object to provide a tie which is simple of construction,durahle, and yet very cheap of manufacture and in the construction of which a much smaller amount of wood is consumed than is now used for the ordinary wooden tie, the wood to a great extent being replaced by some durable material. The importance of cutting down the vast amount of wood now used for ties, as has been pointed out in my former application, filed October 4, 1904, Serial No. 227,171, (something like eight hundred million ties being now in use in this country,) is generally understood as making it necessary to protect the forests. The invention consists in the'details of construction and combinations of parts. hereinafter described, and more particularly pointed v out in the claims concluding this specification.

In the accompanying drawings, illustrating the preferred embodiment of my invention, which is intended as an improvement on that forming the subject of my previous application hereinbefore mentioned, Figure 1 is a plan view of a sheet of metal marked out for the casing of a tie, showing the position of the rivet and bolt holes therein. Fig. 2 is a perspective view of said casing when bent into shape with the end flaps partly turned in. Fig. 3 is a plan View of a section of track, showing two complete ties and sections of rails in place thereon, each tie having the wood sections arranged differently therein and each havinga different style of rail-holding top plate. Fig. 4 is' an end view of one of said ties. Figs. 5, 6, and? are plan views, respectively, of diflerent arrangements of wood and wood-and-concrete fillings for the.

upper part of the ties. Fig. 8 is a vertical cross-sectional view taken through the wood filling on the line 00 w on either of the Figs. 5, 6 or 7. Fig. 9 is a similar view taken through the concrete filling of the upper portion of the tie on the line 3/ y of either Figs. 6 or 7. Fig.

10 is a broken sectional view on the line a 2' of Fig. 7, taken through the drain-passage running from the recess holding the wood to the end of the tie. Fig. 11 is a similar view of a different form of wood recess and block therefor, and Fig. 12 is a broken sectional view showing the form of screw-spike which Iprefer to use on the inner side of the rails.

While the preferred embodiment of my in-.

vention is fully illustrated in the accompanying drawings and its construction and operation is described in the following specification, the right is reserved to make such changes from the constructions shown and described herein as the scope of the claims hereto appended will permit.

In carrying out my invention I cut the casing for the tie from a single sheet of metal, as shown in Fig. 1. The sheet is then bent into the form shown in Fig. 2 with a broad base and a narrower upper portion. Said casing has end flaps which are folded in to close the ends thereof. The broad'base of the casing is filled with concrete or similar substance, and strips or blocks of wood of much smaller size than the ordinary Wooden tie are placed either together with concrete or alone in the upper part of the casing and bolted in place between the upstanding flanges. Said casing is provided with a series of holes preferably drilled before the sheet is bent in said upstandingflanges and in the upper horizontal portions of the casing. By means of the latter holes angular brace-bars are riveted permanently to the casing with their other flanges providde with perforations registering with the holes in the upstanding flanges of the casing, and bolts are passed therethrough for holding the wooden block in place. Rail-holding plates having their ends turned over to engage the outer flanges of the rails are placed on the top of the tie over the wood blocks and are secured thereto by spikes having their heads engaging the inner flanges of the rails. Said rail-holding plates may be made in various length, as shown in Fig. 3. Where the wooden blocks are arranged inward from the ends of tie drain-passages are formed in the concrete from the wood sockets to the ends of the tie. These sockets may be understepped at one end and the block provided with an extension adapted to project into said stepped portion, whereby it is secured against upward movement at that end and can only be removed from the other end. A

Referring more particularly to the drawings, 1 is the bottom of the casing, 2 indicates the sides or vertical portions of the broad base, 3 the upper horizontal portions or steps of said base, and 4 are the upstanding flanges. The bottom 1 is provided with the end flaps 1, and the

other portions

2, 3, and 4 are also provided each with

flaps

2, 3, and 1, respectively, as in my former application. In forming the tie the flaps are turned in, as described in said application. The base of the tie is filled with concrete 5 in all the forms shown. In Fig. 5 is shown a single filling strip of wood 6 for the upper portion of the tie, as in my former application. In Fig. 6 the central portion of the upper part of the tie is filled with concrete, as at 6, and the ends are filled with short sections of wood 7 extending from the end about one-third the length of the tie. In Fig. 7 the short strips or blocks of wood 7 are shorter and are arranged in sockets between the middle section 6 and outer end sections 8 of concrete, said blocks arranged below the rails of the track. In the last mentioned form drainpassages 9 are formed in the concrete from the sockets to the ends of the tie in order to permit moisture to run off and prevent rotting of the blocks of wood. As shown in Fig. 11, the recess is undercut or stepped at 10 at the end nearest the end of the tie, and the block is correspondingly cut, as at 11, to fit thereunder. This formation prevents the rising of the blocks out of the cavities. The blocks are preferably made reversible, as shown, so that they may be removed, inverted, and again inserted for further use. Smaller and shorter blocks of wood than could otherwise be employed in railway construction, including softer woods and even pieces of old ties that are sound, might be used for this purpose, as they are covered by the rail-engaging plates.

The reinforcing angle-bars 12 are permanently riveted to the upper horizontal portions of the casing at 13, as has already been described, and they are secured with the upwardly-extending flanges to the wooden blocks by transverse bolts 1 1. Said angle bars greatly strengthen the upper narrow portion of the tie, making it possible to do away with the cover-plate of my former application. The rail-holding plates 13, made, as in said application,either sectional or extending all the way along between the rails, have their outer ends turned over, as at 17, to engage the outer flanges of the rails and are provided with holes along the inner flange for the spikes. I prefer to use a screw-spike 17 as shown in Fig. 12, for holding said plate and the rails in place, as its use tends to avoid the shock caused by the hammer-strokes in driving the spikes and also lessens the chances of splitting the wood.

The present invention has all the advantages of my former one and at the same time eliminates the cover-plate and still further resever? stricts the amount of wood consumed in the manufacture of the ties. As in the former case, the parts are made interchangeable.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A railroad-tie comprising a casing formed with a broad lower portion or base and anar rower upper portion, a concrete filling for the lower portion and a filling for the upper portion consisting of part concrete and part wood.
