SPECIFICATION forming part of Letters Patent No. 517,302, dated March 27, 1894.

Application filed April 22, 1893.

To all whom it may concern.-

Be it known that I, ALBERT E. ROBERTS, a citizen of the United States, residing at Norwalk, county of Huron, State of Ohio, have invented certain new and useful Improvements in Metal Railway-Ties, of which the following is a specification.

In the accompanying drawings, wherein like reference letters indicate like or corresponding parts:Figure 1, is a perspective View of my improved seat-block in use. Fig. 2, is a top plan of a metallic railway tie showing the manner of operating my improved seat-block. Fig. 3, is a side elevation of the same. Fig. 4, is a vertical section in line 4t4 of Fig. 3, looking to the left. Fig. 5, is a horizontal section in line 5-5 of Fig. 3. Fig. 6, is a top plan of a modified form of my improvement showing the rail in position. Figs. 7, 8, 9, 13, and 14., are modifications adapted to use spikes. Figs. 10 and 11, show my improvement in use at rail-joints. Fig. 12, is a tie with oblong bolt-holes, and Fig. 15, is the bolt designed for use upon the same.

In Letters Patent No. 494,029, granted me the 21st day of March, 1893, for an improved metallic railway-tie, I described and illustrated a L |-shaped tie having a rectangular block fitted into it as a seat for the rail. My present invention is an improvement on that construction, designed to facilitate the connection of the rails to the ties and to stiffen and strengthen the connected structure as a whole.

My improvements consist, first, in so constructing and arranging a seat-block within the vertical walls of a L shaped metallic tie, that it may be partially turned on its vertical axis, within the tie, to facilitate the insertion and removal of the rails; secondly, in providing the said seat-block .with two or more projections adapted to look over the opposite edges of the rail-flange when the rail is in place and thereby lock the rail down upon the tie; thirdly, in providing said revoluble seat-block with a serrated or undulated flange adapted to engage with a similar part upon the tie to prevent displacement and to prevent the seat-block being turned except when slightly lifted, or the vertical sides of the tie are slightly spread, to enable the serrations or undulations to clear each other;

and fourthly, in providing in said revoluble seat-block, spike-holes of a peculiar form adapted for the reception of spikes to hold the abutting ends of the rails or to lock the rails in addition to the lock effected by said projections.

In the drawings A represents the l lshaped tie, B, the seat-block, G, the rail, and D, a transverse bolt extending horizontally through the seat-block and sides of the tie, to secure the seat-block to the tie and prevent it turning when in use, said bolt being provided with a head at one end and a screwnut at the other to keep the seat-block in place and prevent the walls of the tie spreadlng. 7

My first improvement consists in so constructing the seat-block B, that upon the removal of the bolt D, it can be turned partially around its vertical axis without removing it from between the walls of the tie. To this end two diagonally opposite corners of the seat-block are rounded to a quarter circle, thereby enabling the block to be turned in its seat to the extent of ninety degrees in one direction, and then turned back to its proper position without removing it from said seat. The two diagonal corners which are not rounded afiord a sufficiently large and firm base for the support of two locking projections b 19 formed on the upper surface of the block for the purpose of engaging with the flanges of the rail and locking the rail upon the seat-block. These projections are inclined inward over the rail-flange, as shown in the drawings, the larger projection coming at the outer side of the rail, and, preferably, being so shaped as to fit against the web and-under side of the tread, thereby acting as a chair for the support of the rail against outward thrusts. It is obvious that a circular seat-block may be used if preferred, but in such case there is no satisfactory bearing for the projections b, b and the turning of the seat-block might not release the rail. Spikes might be used, however, in place of said projections, and one or more spikes be withdrawn to release the rail.

In practice the seat-block is constructed of malleable iron, or steel, and if at any time the rail becomes loosened, a sharp blow upon the projections b b will set them tightly upon the rail-flange, thus firmly securing the rail again.

A further improvement consists in forming the serrated or undulated part b in the seatblock and the corresponding part a in the walls of the tie. This may be done upon one side only of the seat-block and rail, or on both sides, as desired. These parts fit or mesh together and aid in firmly securing the structure. They also allow the seat-block to be adjusted longitudinally outward and thus widen the gage of the curves. To adapt the bolt D, to permit this slight adjustability, I make the holes a a in the tie oval or oblong, as shown in Fig. 12, and I prefer to use abolt with a shoulder (1 upon one side, as shown in Fig. 15. In this form, the bolt may be turned, bringing the shoulder (Z on one side, or the other, filling the oval bolt -hole, and thus slightly moving the seat-block for the purpose named. (See Fig. 12.) In such case the serrations in the block mesh with the next succeeding set in the corresponding part of the tie, backward or forward as the case may be. This function may also be accomplished by making the bolt-hole through the seat-block oblong, using, if desired, circular bushings to fill up the unoccupied part of the bolt-hole. But unless it is desired to widen the gage,a plain hole in both tie and block and an ordinary bolt or rivet may be used, as first described.

Another improvement consists in the use of spikes E, to attach the rail to the seatblock or to combine with the action of the projections 11' b for that purpose. When it is designed to use spikes, I construct the seatblock B with spike-holes 1) formed therein. The spike-holes are so formed that when the spike is driven and conforms to the hole it is bent to form three friction contacts with the block (see Figs. 9, 13, and 14), one bend and contact point is at e, one at e, and one at e. These bends prevent the accidental pulling of the spike and serve to hold the head of the spike tightly against the flange of the rail. The seat-block in this form is constructed with openings c, extending from the outside of the block to the spike-holes, as shown in Figs. 13 and 14, and in case the head should be broken off, the spike can be readily cut with a proper tool through such openings and the spike thereby be easily removed. The pulling of the spike does not materially injure it and it may be used again.

I am aware that seat-blocks have been made in which spike-holes are constructed in such a way that in driving the spikeit isbent, and also that, in some cases, the lower or pointed end is given a partial turn or twist, and I do not claim such construction, neither do I claim a seat-block in which the spike is driven slantingly or inclined and the end turned down.

The mode of operation is as followsz-The tie is first set and the seat-block placed loosely therein, in the position shown in dotted lines in Fig. 2. The rail is then placedin position and the seat-block is turned causing the pro jections b b to approach the rail and,fitting closely over the rail-flange, to secure it to the seat-block. The bolt is then adjusted, thus securing the whole structure. In removing a rail the operation is reversed, and an entire rail may be quickly removed and replaced by another without disturbing the ties or the other rails.

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

1*.--In a device of the kind described, ametallic shaped tie, having bolt-holes opposite one another in the sides of the same,and a bolt adapted to extend horizontally across the tie and through said bolt-holes; in combination with a metallic seat-block adapted to fit into the tie, and so formed as to permit of being revolved on its vertical axis within said tie; a horizontal bolt-hole extending through the seat-block in line with the boltholes in the tie, adapted to receive the tiebolt; and means for securing the rail to the seat-block; substantially as described.
