RAIL-JOINT.

- Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed August 8,1906. Serial No. 329,725.

To ail whom it may concern:

Be it known that I, MATHIAS NEMECEK, a subject of the Emperor of Austria-Hungary, residing at McKeesport, in the county of Allegheny and State of Pennsylvania, have in vented certain new and useful Improvements in Rail-Joints, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in rail-joints; and the invention has for its object to provide a novel rail-chair to which the confronting ends of two sections of rails can be easily and quickly clamped.

My improved rail-j oint prevents lateral and vertical displacement of rails and practically forms a continuous tread for rolling-stock.

The detail construction of my improved rail-joint will be described, and specifically pointed out in the appended claim; butreference will first be had to a drawing forming part of this specification, wherein I have illustrated the preferred embodiment of my invention,

In the accompanying drawings, Figure 1 is a perspective view of my improved joint. Fig. 2 is a cross-section of the same, and Fig. 3 is a perspective view of the chair or base of my improved'joint.

The rail-joint is principally composed of two elements-a chair 1 and a fish-bar 2- both of which are adapted to

embrace rails

3 and 4 and be secured together by bolts and nuts 5.

The chair 1 comprises a base-plate or railseat 6, having a reinforced integral fish-bar 7 upon its one side adapted to engage the one side of the tie-flanges 8 and the webs 9 of the

rails

3 and 4. The opposite ed e or side of lateral movement, so that the lateral strains upon the fish-bar 2 are very materially reduced. This is an important feature of the invention and adds materially to its efficiency and strength without increase of weight or expense of manufacture. The seat 10 at the inner side of the groove 11 is provided with two vertically-disposed boltopenings 12, which. terminate in rectangular recesses 14, formed in the bottom of the chair 1. The outer edges of the chair are provided with. a plurality of spike-openings- 15, whereby said chair can be secured to a tie or sleeper.

The fish-bar 2 is adaptedto rest upon the seatlO and embrace the opposite sides of'the

rails

3 and 1 from that of the fish-bar 7. The bar 2 is formed with a tongue,16 adapted to snugly fit'within the groove 11 of the chair 1 and hold said bar against the

rails

3 and 4. The bar 2 is also provided with bolt-openings 17 adapted to register with the openings 12 of the chair when said bar is properly seated.

After the

rails

3 and 4 have been placed upon the chair 1 and the bar 2 placed in position the bolts and nuts 5 are employed to secure the bar 2 upon the chair, the rectangular heads 18 of the bolts engaging in the recesses 14 of the chair 1 and preventing said bolts from rotating while the nuts are being placed thereon. It is obvious that the bar 2 serves functionally as a wedge to force the

rails

3 and 4 against the bar 7, thus insuring a positive gripping of said rails and obviating any tendency on the part of the rails to spread, especially when the chair has been firmly secured to the ties of a road-bed.

My improved chair and fish-bar are constructed of strong and durable metal, which may be cast, rolled, or drop-forged.

What I claim, and desire to secure by Letters Patent, is A railway-rail joint comprising a base portion having an integral fish-bar adapted to bear against the tie-flange and vertical web of the rail at one side and with an upwardlyextending rib adapted to ,bear against the tie-flange at the opposite side and with a dovetail groove spaced from said rib and in- -lined to the longitudinal plane of the base,

and a fish-bar bearing over the tie-flange and l In testimony whereof I afliX my signature against the1 vgticallweb of tllle rfiii at the in the presence of two Witnesses.
