COMBINED RAIL-BRACE AND TRUSS-FASTENING FOR RAIL-JOINTS.

SPECIFICATION forming" part of Letters Patent No. 474,128, dated May 3, 1892. I Application filed November 9 1891. $erial No. 411,282. (No model.)

To all whom, it may concern:

Be it known that I, FREDERICK H. HEATH, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain Improvements in a Combined Rail-Brace and Truss-Fastening for Rail-Joints, of which the following is a specification.

My invention relates to means whereby rails are at once braced and their joints firmly and solidly fastened; and the object of the invention is to make the rail-joints as Strong as any other part and to provide simple and economical means for so doing.

To this end my invention consists in the combination, with the rail or rails, of a plate whereon thesame rest, said plate extending across the tops of the ties and provided with a central depending truss having its ends formed by laterally extending parts and trusses arched over the top of the plate at the sides of the same, one of said trusses provided with an extension or extensions extending into engagement with the tread of the rail or rails to brace the same, said part or parts extending inwardly and upwardly from the truss parts; in a plate whereon the rails rest and itself resting upon the ties andprovided with upwardly-extending trusses on its upper surface adapted to strengthen the middle part of the plate and with a brace extension or extensions engaging the rail-top; in means combined with the above for securing the rails thereto, and in various details of construction and in combinations, all as hereinafter described, and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings, in which- Figure 1 is a side elevation showing a combined joint and brace embodying my invention. Fig. 2 is a sectional View thereof on the line a: 00 of Fig. 1. Fig. 3 is a view of the other side of the joint shown in Fig. 1. Fig.

I is a side elevation of a similar joint, the

same differing from the other merely in the use of a single brace-extension in place of the two extensions shown in Fig. 1. Fig. 5 is a cross-section on the line y y of Fig. 4. Fig. 6 is an elevation showing the other side of the joint shown in Fig. 4:. Fig. 7 is a sectional View on the line a z of either one of the railjoints and showing top trusses and the extended edges of the ends of the plate, whereby 1 the plate is given a greater bearing-surface on the ties.

As shown in the drawings, the thin plate 2 extends across the two ties 3 and is provided on each end for a distance equal to the width of a tie with the extended edges 4, whereby a wide bearing is secured on the tops of the ties. same width as the rail-base 6, so that the clamp 7 may, if necessary, be forced clear against the edges of the base. This narrow part is long enough to accommodate the clamp 7, and then the rest of the plate is widened by the formation on the edges thereof of the Vertical arched trusses 13 and the flanges 8, between which the rail-bases fit quite snugly, as shown plainly in Figs. 2, 5, and '7. The under side of the plate is strengthened by the depending truss, consisting of the web 9, the rib 10, and the transverse and the diagonal parts 11 and 12, respectiVely.- All of these parts are cast integrally with the plate and are fully described and claimed in my prior applications on rail-joints. The outer ends of the arch trusses formed on the top surface of the rail-plate extend about half-way over onto therail-chair ends of the platethat is, the parts of the plate covering the ties. It will be seen that the upper ends of the depending truss merge into the bottom of the plate about at the junction of the same with the inner edges of the ties 3. The office of the top trusses is to strengthen the plate at just these points to prevent the springing or breaking of the plate over the edges of the ties. I therefore raise the highest points of the top or arch trusses above these points and carry theinner ends thereof back to the meeting points with the ends of the clamp 7. As shown in the different figures, so long as this strengthening is accomplished the specific form of the top trusses may be altered somewhat. For instance in Figs. 1, 2, and 3 the inner ends of the top or arched trusses 13 are integrally joined by the connection 14 springing over the clamping-blocks 7, thus tying the ends firmly together and greatly strengthening the whole joint. In connection with The middle part 5 of the plate is of the these arched trusses for strengthening the plate over the junctions with the ties I provide other upwardly-extending parts for bracing the rail or rails. These braces are arranged on the outside of the rail, and, as shown in Figs. 1 and 2, consist of upwardly and inwardly extending lugs or plates 15, raised upon the ends of the trusses 13 and from the low ribs or flanges 8 and formed integrally therewith. Each brace 15 is provided with a longitudinal notch or groove to accommodate the corner 17 of the rail-tread, and being slanted inwardlythey form very strong rail-braces. In place of these braces 15 I may provide one solid brace-plate 18, as shown in Figs. 4, 5, and 6, and formed directly with and above and between the inner parts of the arch trusses. With this construction I gain an exceedingly-strong supplemental truss or brace directly over the middle of the plate. Owing to the size of the brace-plate 18 it gives the rail a greater rigidity and strength than would result from the use of a part let on both sides of the plate. I therefore cut out a portion corresponding to a part 14 on the opposite side of the Figl-and-G plate and terminate the inner ends of the trusses 13 at the points where they meet the ends of the block 7, thereby in some respects rendering the plate easier to mold.

All parts of my combined truss joint and brace are cast integrally and of soft steel or malleable iron, and owing to the strengthening qualities of the several trusses all parts may be made thin and light. The bolts 20, which secure the clamping-blocks 7, pass through openings provided in the web of the depending truss. The rails are fastened upon the ties by usual spikes 21, which are accommodated by notches provided in the extended edges 4: of the plates. 1 thus provide a light, strong, cheap,and durable rail joint and brace in which no holes or bolts passing through the rail-web are used.

Any convenient means may be provided in connection with the plate for preventing the rails from sliding thereon.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
