Description
Patented Nov. 6, 1923.
a armes lJNlTE lanas@ MIGUEL ALVAREZ, OF SANTIAGO, CHILE.
RAIL JOINT.
Application filed April l0, 1920. i Serial No. 372,949.
T all whom t may concern Be it known that I, MIGUEL ALVAREZ, citizen of the Republic ot' Chile, and residing at Santiago, Chile, Avenida El Salvador No.
2059, have invented a new and useful Improvenient in Rail Joints.
rIhis invention reers to a new system for the joining or" rails of tramcars and wagons, Whose object is to eliminate the movement of the rails at their oints, thus avoiding the troublesome blow to passengers and at the same time the damage that is caused to the rolling stock and the wear and tear of the rails.
This invention consists of boring the rails transversely at the ends of both and afterwards intro ducinw a tightly fitting hard steel aluof.
l Tthis system has been practically used and it has been proved satisfactory, leaving intentionally the ish-plate in a loose condition, having observed that the rails have had no relative movement whatever and entirely eliminating the blow on the passing of the i cars.
The diameter of the plug may be varied according to the cargo and the normal use of the top part of the rail, it being applicable both to the Phoenix and Vignol rail, and
:so where the rails are imbedded by pavement -or soil.
Referring to the drawings, Fig. l shows the joining of the rails l and 2 with ish plate 3 and bolts A placed. 5 is the plug in its position. Fig. 2 shows an end view of the rail with the plug placed. f
Fig. 3 is a side view of a modification which permits expansion and contraction of the rails.
Fig. Ll is an end view of the modified arrangement.,
rthis invention is also applicable to railroads that are subject to a periodi-cal expansionv and contraction.
In this case the plug in the form of an elongated key, is placed at certain distances which on being` introduced on the corresponding slots in both rails, allow of a longitudinal movement of the rails.
rlhe other joints are made up with the common cylindrical plugs.
The distance between the elongated plugs is fixed according tothe country and climate where this invention is to be applied.
I am not aware that prior to my invention, tramcar rails have been oined according to my system, and therefore I claim:
l. In a rail joint, the combination with the ends of'two rails arrangedv end to end and having heads provided with oppositely 50 disposed transversely arranged horizontal recesses extending inwardly from one side of the heads, of a solid bridge plug arranged in said recesses and designed `to prevent relative vertical movement of the ends of the 55 rails.
2. In a rail joint, the combination with the ends of two standard rails arranged end to end and having heads provided with oppositely disposed transversely arranged horizontal recesses extendinoa inwardly from one side of the heads to a point adjacent the transverse center of the heads, of a hard metal plug removably arranged in said re cesses and designed to prevent relative vertical movement oit the ends rof the rails.
In testimony whereof I have signed this specification this 9th day of March 1920.
MIGUEL ALVAREZ. Witnesses: f
WALTER J. TINGLE, L. CARNECKER.
