METALLIC RAILWAY-TIE AND RAILFASTENING.

Application filed June 7, 1910. Serial No. 565,607.

I?) all whom it may concern:

Be it known that I, JOHN W. STEPHEN- ing drawings, forming part of this SPQClfl-V cation, in which Figure 1 1s a slde View of a rail tie em- .bodylng my invention and showing main and guard rails secured thereto; F g. 2 1s a plan view partly broken away of one end portion of the tie; Fig. 3 is a: longitudinal vertical section of the same taken on the line III-III of Fig. 4; Fig. 4 is a plan view of a portion of a tie partly broken away, with the rails and fastening members removed; and Figs. 5, 6, 7 and 8 are detail views of part of the rail fastening and adjusting devices hereinafter more fully dedetail in plan in Fig. 5).

scribed.

My invention relates to railway ties and rail fastenings, and has been especially do signed to provide a metal tie adapted for use in supporting both main and guard rails having securing and adjusting devices of the character described and claimed in my pending application for patent, Serial No. 540,806, filed March 8, 1910.

The nature of my invention will be best understood by reference to the accompanying drawing, in which I have shown the preferred embodiment thereof, and which will now be described, it being premised, however, that various changes may be made in the details of construction and arrangement of the parts, without departing from the spirit and scope of my invention, as defined in the claims.

The particular form .of tie which I have illustrated in the drawings is formed in two .sections 2 and '3, placed end to .end, and connected by a pivot bolt 4, passing through engaging end portions of the two sections.

My invention is not, however, limited as to v all its features, to the use of a sectional tie,

since some of these features are applicable to a metal tie made in one piece.

In the form shown, each of the tie sections consists of a fiat top portion having a depending flange 5, at each of its lateral edges, and also having a depending zigzag web 6. The flanges 5, to ether with the web *6, are preferably of ecreasing depth toward the outer ends of the sections. Each of the sections is provided with upwardly and inwardly inclined rojections 7 and 8, at opposite sides of tile main rail 9 and guard rail 10. These projections are preferably reinforced and braced by the inclined webs 11. The inner faces of these projections are preferably provided with inclined faces 12, and the projections are also preferably arranged obliquely so that these faces will have a wedging action. Between these projections, the top portion of the tie sectio-n is provided with a depression 13, which forms a seat for sliding shoe 14 (shown in This shoe is provided with a lip 15, at one end which extends underneath the inner base flange of the main rail 9, as shown in Fig. 3, and is also provided with another lip 16 for engaging the flange 17 of the guard rail 10. At the opposite end, the shoe is provided with the upwardly extending projections 18, having the rear shoulders 19.

The main rail 9 is secured in place against upward movement by means of a brace member 20, which is driven between the in- .clined inner face 12 of the projections 7 and the web of the rail, said brace member fitting the base and head of the rail and seating upwardly underneath the rail head into supporting engagement therewith. This 7 brace member 20 is secured by means of a bolt 21, extending therethrough and alsohaving a bearing in a portion 7 at one end voifthe PEOJGCUOH 7. The inner base flange of the rail 9 engages a lip or lips 9 on the tie, being such lip by the brace 20.

Theguard rail 10 is seated on the sliding shoe '14,, with its flange 17 engaging the lip held in engagement with 16, and is secured against movement on the shoe away from the main rail 9 by means of a brace member 22, which is similar to the brace member 20, and which seats between the projections 18. It is held in place by a transverse wedge 23, which is driven be hind it through seats in the projections 18.

The sliding shoe 14: is movable toward and away from the main rail, and is provided with an adjusting bolt 24, which engages its inner end and extends outwardly through a bearing in the projection 8, a spring 25 being interposed between said bearing and the head of the bolt. This spring merely has to draw the shoe and guard rail away from the main rail. The shoe is secured in its adjustment by means of the wedge member 26, which is driven between the shoulders 19 of the projections 18 and the wedge faces 12 of the projections 8 on the tie. This wedge 26 is secured by a bolt 27. The wedge 23 is shown in detail in Fig. 7, and the wedge 26 is shown in detail in Fig. 6. F 8 is adetail sectional view of the brace member 22. This member has a lip 28, upon which the wedge 23 is driven.

The devices herein shown and described for securing the rails are more fully described and are claimed in my pending application above referred to. My present invention, however, provides means whereby these fastening devices may be mounted directly upon the tie itself, instead of upon a tie or base plate, as described in said application, the projections 7 and 8 and the guide for the sliding shoe being preferably formed as an integral part of the tie. I do not therefore claim broadly herein the fastening and adjusting means shown and described, nor do I claim broadly herein a metal tie formed in sections, as such a tie is described and claimed in my application, Serial No. 565,605.

My invention provides a tie suitable for supporting both main and guard rails, without the use of a separate tie plate. The manner in which the guard rail is sup ported by means of the sliding shoe, so that its base flange extends over the inner base flange of the main rail, avoids the necessity of cutting away the flange of the guard rail, and for notching or recessing the base flange of the main rail to receive securing spikes. It also provides means of simple character whereby the distance between the main and guard rails may be easily adjusted to compensate for wear. Both main and guard rails are also securely held and braced.

Although my invention is applicable to atie formed in one piece, I prefer to employ a sectional tie, since by forming the tie in sections capable of independent vertical movement, an element of resiliency is imparted to the tie which is very desirable.

Each end section is free to move vertically somewhat under passing trains, thereby overcoming the objection of rigidity which has been urged against metal ties heretofore used. This feature of the tie is, however, more fully described and claimed in my pending application, Serial No. 565,605 above referred to. The Zigzag web provides means whereby the tie may be properly tamped in the road bed or ballast in a manner to prevent movement thereof either endwise or in the direction of the track rails.

I claim:

1. A metal railway tie having integral rail-supporting surfaces near its ends, and having guideways shaped in its upper surfaces adjacent to said rail-seating portions, sliding members seated in said guideways, and means for securing the guard rails to said sliding members, together with means for adjustably securing said sliding members; substantially as described.

2. A metal railway tie having integral rail-supporting surfaces at its end portions, and also having means for securing the main rails directly thereto, said end portions also having guideways'shaped in their upper surfaces, and guard rail supporting members adjustably seated in said guideways and adapted to support guard rails with their bases at a higher level than the bases of the main rail; substantially as described.

3. A metal railway tie having a rail supporting surface in substantially the plane of its upper face and adapted to support main rails and guard rails, and having at each end portion an integral upward projection,

said projections having inner wedging faces and being at opposite sides of the rail seating faces, substantially as described.

4. A metallic railway tie having each of its ends provided on its upper surface with a rail seating portion in substantially the horizontal plane of the upper surface of the tie, a guideway formed therein, a sliding member seated in each of the guideways and provided with means for securing a guard rail thereto with its base elevated above the seat for the main rail, means for adjusting the guard rail toward and away from the main rail, and means for securing the main rails to said seating portions; substantially as described.

5. A metal railway tie having integral projections thereon, said projections having undercut wedging faces and having a longitudinally extending recess or guideway between the projections, said guideway being formed in an integral portion of the tie and between said projections substantially as described.-.

6. A metal railway tie having an end portion provided on its upper surface with a the base of the adjacent main rail; substanseat for a main rail, integral projections adtially as described.
