SPECIFICATION forming part of Letters JPatent No. 433,571, dated August 5, 1890. Application filed April 19, 1890. Serial No, 348,631. (No modelt) To all whom it may concern:

Be it known that I, AUGUST KLEIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain. new and useful Improvements in Rail-Joints; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same.

My invention has relation to improvements in railway-rails of a construction adapted to effect a secure joint at their meeting ends, and it will be fully understood from the following description and claim, taken in connection with the accompanying drawings, in which Figure l is a longitudinal elevation of two railway-rails embodying my improvements in a joined position. Fig. 2 is a similar view of the same, a portion being broken away at their junction to show the manner of construction. Fig. 3 is a perspective view of the end of rail carrying the dovetail projecting tongue and the recess for the reception of the projecting lug of adjacent rail, and Fig. 4 is a perspective view of the end of rail provided with the dovetail recess for the reception of the dovetail tongue of adjacent rail and carrying the lug projection to take into the recess of opposite rail.

It will be understood from the following description that my improvements are of a construction such as may be formed with the rail at the time of manufacture, or in rails at present in use, as they in no manner alter the general construction of the same.

In carrying out my invention I take a railway-rail, which may be of the ordinary construction, and form in the bottom thereof at one of its ends a dovetail groove or recess B, for the reception of a tenontongue projecting from the bottom of the end of an adjacent rail. This dovetail groove or recess B is of a length and width in proportion to the size of the rail, and it is obvious that by its being formed at the point described the rail is in no manner weakened, but rather strength ened, for when the dovetail tenon or tongue is in position in the groove it takes the place of the displaced metal thereof, and by breaking the joint between the two rails affords a juncture thereof capable of resisting lateral eration takes into a similarlysituated recess or opening in the end of the rail carrying the projecting tongue. At. the opposite end of the rail from the one described, and which is better illustrated in-Fig. 3, I form a projecting tongue or tenon D, of dovetail configuration, which is of a size to take-into the dovetail recess of the adjacent meeting rail, as has been described. This dovetail tongue projection may be either cast integral with the rail or securely fixed therein; but the former construction is preferable, as it makes a construction of greater strength and renders the manufacture of the rail more simple.

E indicates the recess or opening for the reception of the lug G, which occupies a position in one end of the rail similar to that which the lug occupies upon the other.

It will be obvious that by having the projecting dovetail tongue and the recess upon one end of the rail and the dovetail recess and the projecting lug upon the other end, when the opposite ends of two rails are put together a strong juncture will be effected which will prevent lateral spreading of the rails by reason of the jointbetween the two being broken, and it will also be observed that the rails may be quickly put together and secured in a true line without inconvenience, fish-plates being dispensed with, if desired.

Having described my invention, what I claim is- The combination, with a railway-rail, of the dovetail groove formed in the bottom thereof at one end, the dovetail projection extending from the opposite end at the bottom thereof,

the stud or lug projecting from the T portion of the end having the dovetail groove, and the recess formed in the T portion above the clovetail projection, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
