PORTABLE FURNACE FOR HEATING RAILS.
SPECIFICATION forming part of Letters Patent No. 778,117, dated December 20, 1904. I
Application filed July 8,1903. Serial No. 164,719.
T0 aZZ whom, it nuiy concern:
Be it known that I, GUSTAV AMANDUS AN- DREAS CULIN, a subject of the German Emperor, and a resident of Hamburg, Germany, have invented certain new and useful Improvements in Portable Furnaces for Heating Rails orthe Like, of which the following is a specification.
My invention relates to furnaces to be used in the re-formation of deformed rails and girders of all kinds, more particularly deformed rail ends of railway-tracks, without removing such rails from their places.
The extremities of rails of ordinary and street railways upon which the wheels run are deformed by thehammering action of the wheels. The end of each rail upon which the wheels first roll receives an indention, the
material at the same time spreading laterally, and the rail end which the wheels leave is rounded off.
My invention consists in an improved portable furnace adapted to heat the parts which receive these shocks and which it is desired to repair; and it comprises a trough-shaped box having a suitable fireproof lining and a specially-constructed grate formed to fit on 'or over the girder or rail and extend down on.
both sides of the web, thus almost completely encompassing the rail, whereby a rapid, thorough, and uniform heating of every part is insured.
In the accompanying drawings-Figure 1 is a vertical cross-section of the improvedfurnace or heater; Fig. 2, a plan or top view of the same, and Fig; 3 illustrates a modification.
Similar characters of reference denote similar parts throughout the several figures.
A trough-shaped sheet-iron receptacle, as l, is lined internally with chamotte blocks or plates, as 2, an intermediate layer of asbestos plates being provided, if desired. A frame for holding and transporting the receptacle consists of four standards 3, each of which has an inwardly-extending bracket conforming tothe shape of the box and acting as braces for its two sides. The receptacle is arranged with its lower smaller aperture on suitably-shaped cross-supports 4:, which may be rigidly connected with the brackets, and
these cross-supports are united so as to form upper part of the receptacle is tightly closed by a cover 6, of sheet-iron lined with chamotte. 1n the top of this cover is fitted an air-admission pipe 7, from which appropriate nozzles 8 extend into the receptacle. When this receptacle or furnace is placed upon the object to be heateda rail or girder, for example and a blast formed by means of powerful bellows, the current of cold air will first of all have to traverse the upper incandescent layers of coke, which will raise it to a high temperature, in which condition it reaches the lowest layer of coke resting upon the grate, making it highly incandescent, the direction of the air-current being indicated in the drawings by arrows. In this manner not only the highest layer of coke, but also the whole of the combustion-air, which is at a very high temperature, is brought, owing to the shape of the receptacle and grate, into extremely intimate contact with the part to be heated, so that the desired temperature is obtained in the shortest possible time. If it is desired to heat the whole surface of the girder or the like, the grate 4 5, Fig. 3, is arranged to duits 9, with nozzles 10, are provided, which, if necessary, are supplied with separate bellows if the section to be heated is very large.
It is obvious that one and the same furnace may be used in conjunction with different forms of grate for different sections.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-
1. An apparatus for heating rails, girders and the like comprising a fireproof receptacle open at the bottom, standards for supporting the same, cross-bars connecting the Standards projecting into the receptacle at each end, and a plurality of longitudinally-arranged bars 'mounted in the cross-bars, for the purpose specified. g
2. An apparatus for heating rails, girders and the like comprising a bottomless'fireproof receptacle having downwardly-converging sides, standards supporting said sides, crossbars connecting said standards in pairs and cover the entire section, and lateral air-con-- a grate by means of longitudinal bars 5. The

projecting through the bottom of the receptacle near the end Walls thereof, and a plurality of longitudinally-arranged bars mounted in the cross-bars forming a chamber in the re-.
ceptaele on each side of the cross-bars.
3. An apparatus for heating rails, girders and the like comprising a bottomless fireproof receptacle having downwardly-converging sides, standards having inclined brackets adapted to embrace the sides, cross-bars connecting the brackets and projecting into the
