J OHN HENRY KOSSMANN, OF ST. LOUIS, MISSOURI.

RAILWAY-RAIL JOINT.

Application filed March 18, 1918.

To all whom it may concern:

Be it known that I, JOHN HENRY Koss- MANN, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Railway-Rail Joints, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to an improved railway-rail joint, and consists in the novel construction hereinafter described, and as particularly pointed out in the claim found at the end of this specification. V

The object of my invention is to increase the durability of railway rails at the joints thereof, by providing a very strong reinforcing and supporting construction for the rails at the joints; and a construction which will be simple and inexpensive in manufacture and use; whereby the rails will be prevented from being broken, and their life will be lengthened, resulting in economy and durability.

In the drawings,

Figure 1 is a vertical transverse section of my improved rail-joint, I

Fig. 2 is a simialr section, showing a slight modification, and

Fig. 3 is a side elevation of the joint.

The numeral 1 designates the common rails to be joined, and they may (of course) be of any well known form now in use upon the railways of this country, whether steam, electric, or street-railway rails.

The ends of the said rails 1 abut upon and are supported by a horizontal base-flange 2 formed integral with the lower edge of an outer fish-plate 3, and said base-flange is itself supported by an underlying baseflange 4: of an inner fish-plate 5, formed integral with the lower edge of the latter.

'Io firmly secure the two fish- plates 3 and 5 and their base flanges in position toclamp the rail-ends between said plates, as well as to lock the said flanges in the position shown and described, I provide a plurality of separate and independent tie-plates 6 having raised flanges 7, which are sufficiently Specification of Letters Patent.

high to form shoulders or abutments against which the said overlapping parts hear, so that (even without the usual spikes) the rails and the fish-plates will be held securely in the position shown.

The said independent tie-plates 6 are heavy and solid castings, or are rolled or stamped out of metal in an integral solid piece, so as to afiord a strong and unyielding bearing for the parts upon the separate ties 9, and being (as they are shown) separate and independent each tie-plate may be adjusted in its position beneath the base flanges of the fish-plates, to suit the space between adjacent ties, Whether it be greater or less within the limit of the length of said base flanges.

However, to make the, construction still more secure, reliable and permanent, I pass through apertures in the overlying parts of said fish- plates 3 and 5, base-fianges 2 and 4C, and the said tie-plate 6, a number of the usual spikes 8, which latter may be either driven or screwed into the ties 9 after being passed through the said apertures.

In the modification, shown in Fig. 2, both of the fish- plates 3 and 5 are provided with integral base-flanges 10 in the same horizontal plane, and the inner edges of which flanges almost meet at a point beneath the central longitudinal line of the said rails 1, and the opposite base flanges both rest directly upon the said tie-plate 6, and are locked in position by the said flanges 7 near the opposite marginal edges of the said tielate.

P A further modification, which is especially designed for use upon street-railway grooved rails, is an integral upward extension 11 of the upper edge of the outer fish-plate 3, designed to afford thereat a strong brace or reinforcement for the head of the rail with which it rests in contact. (See Fig. 2.)

I claim:

An improved railway-rail joint, comprising two opposite fish-plates having integral base-flanges at their lower edges; the abutting ends of two rails, located upon and supported by the said base-flanges; two solid separate unyielding tie-plates having opposite abutments Which are high enough to In testimony whereof I have signed my prevent spreachng of the base-flanges and name-t0 thls specificatlon in presence of two form beanngs against which the outer edges subscrlbing wltnesses.

of said base-flanges rest; and spikes passing JOHN HENRY KO SSMANN. 5 through registering apertures formed in the WVitnesses:

the tie-plates. JOHN C. HIGDON.
