v Application filed May 29.1890. Serial No. 353.657. (No model.)

T0 all whom t may concern.-

Ie it known that I, JAMES F. MCELROY, a citizen of the United States, residing' at Al bany, in the county ef'Albany and State of New York, have invented certain new and useful Improvements in Car-Heaters, of which the following is a specification, reference bein had therein to the accompanying d rawings.

This invention relates to new and useful improvements in car-heaters5 and it consists in the peculiar construction of a magazinestove designed to give the best results in econo my of fuel, together with safety in case of accident, and, further, in the peculiar construe tion, arrangement, and combination of the varions parts, all as more fully hereinafter described, and shown in the accompanying drawings.

In the said drawings, Figure l is a front elevation. Fig. 2 is a vertical central section on line x x. Fig. 3 is a plan, and Fig. #l is a horizontal section on line y y.

A is the base, preferably cast, and having cast integral therewith the ash-pan B. This base has an annular shoulder C, which supports the outer shell D. This shell I preferably make by taking wrougl'lt-iron pipe of suitable diameter and cutting off a section of Y suitable length, thus forming a seamless casA ing.

E is the cap, having the annular shoulder F and iiange G, the shoulder F resting upon the top ofthe casing D. The cap is provided with an upwardly-extending collar Il, forming within the smoke-exit. The cap is centrally apertured to form a feed-opening, and around this aperture is formed the guide-flange I, the aperture being covered by a suitable cover J, pivoted upon the pin J, and held together in position by means of the spring J2 between the head of the pin and the top of the cover. The cover 'is provided with a locking-recess, which engages with the stud J 3 upon the top casting, being held in its locked .position by the spring J2.

lVithin the easing and across the upper end thereof is secured the perforated plate K, which has upwardly-extending flange L, by means of which this plate is bolted to the outer casin The plate K is centrally apertured, and around this aperture is secured the depending guide-plate M, which has the extension N at one side, having guides N formed thereon, into which the sliding cover O engages. This cover has a suitable handle I) extending through the top, whereby the aperture may be opened and closed by sliding` the cover forward or back.

Q is the smoke-chamber formed between the top plate E and the perforated plate K.

Ris the grate supported on the standards S, which likewise support the `lire-pot S. This fire-pot is provided with the annular iiange d, which supports the inner casing h, which is provided with an inwardly-extending flange c, within which is secured the upper sections dof theinner casing. An air-space@ is formed between the two casings. Tithin the inner casing I form a magazine by means of the coil T, which enters through the casings at f and is coiled within the inner casing, the lowermost helix of the coil g being au open or separated coil and the upper coils being closedthat is, wound so closely together as to form within the magazine-chamber, the coil finding exit at the upper end at 7L.

Between the coil and the inner casing is formed the coinbuStien-chamber `1I.

The parts being thus constructed, their operation is as follows: The operator to till the stove opens the door J and the sliding cover O. The coal is then poured in through the feed-opening, filling the magazine within the coil. A tire being started in the grate, the products of combustion will tind exit through the colnbustionchamber t', thence through the perforations in the plate K into the smokechamber, and thence through the smoke-exit in the stove-pipe. The lower open coils will be heated by the body of the coal resting within and by the heat from the products of combustion passing without.

j is the aslrdoor, which I make of suitable size, so that any part of the grate may be removed therefrom.

In case ot accident the perforated plate K and top plate E will prevent any coal from getting out in case the stove is upset, and if the stove is not upturned the door J will remain closed by gravity. The air-space c be- IOO tween the two casin gs will prevent the outer case from becoming excessively hot, as said air-space connects into the ash-pit beneath, so that a draft ot' air can pass therethrough at all times, suitable dampers 7c being provided in the ash-door for the draft. i' By Inakiug the magazine Within the coil I am enabled to get the best results in heating the Water which passes through the coil and in economy in the manufacture of the stove. of coal Within the coil preventsdamage to the coil in ease of collision. The heat of the coal in the magazine is imparted to the coil and is suflicient to keep the water circulating long after the ireY is out. I am also enabled Wto make a magazinestove which in ordinary railroad use will last for twenty-four to fortyeight hours Without replenishing.

What I claim as my invention is- 1. In a car-heater, the combination of a casing, a Water-circulating coil coneentrically arranged with the casing, arranged to form a fuel-magazine Within the coil, and a combus- The body tion-chamber within the easing outside the coil, a fire-pot, and a top having a feed-opening connecting into the fuel-magazine, substantially las described.

2. In a car-heater, the combination, with the casing and cover having afeedaperture therein, of a pivoted door having a locking-recess, a locking-lug on the casing, and a spring, such as J2, upon the pin holding the door upon the lug, substantially as described.

3. In a car-heater, the combination, with the casing, of the top E, having a feed-opening therei n', perforated plate K,formin g the smokechamber Q, a cover O, sliding in guides N', the handle P, and cover J, substantially as described.

In testimony Whereof I aiX my signature, in presence of twoV Witnesses, this 30th day of April, 1890.
