HEATING AND GAS-GENERATING STOVE.

SPECIFICATION forming part of Letters Patent No. 474,742, dated May 10, 1892.

Application filed December 12, 1891. Serial No. 414,842. (No model.)

To all whom it may concern:

Be it known that we, FLOYD JARRETT, a resident of Socorro, Territory of New Mexico, and LILBURN PEYTON, aresident of Rich Hill,

Missouri, both citizens of the United States,

have invented certain new and useful Improvements in Heating and Gas-Generating Stoves, of which the following is a specification, reference being had to the accompanying Io drawings.

Our invention relates to that class of stoves or portable furnaces having a gas-generating retort located within the fire-chamber of said stove, said invention consisting of certain improvements hereinafter set forth for oo nstructing, charging, or feeding said retort, for closing the mouth of the latter, and for carrying off the gases.

In the accompanying drawings, Figure l is 2o a central vertical section taken through the furnace, retort, and feeding-cartridge, showing the preferred relative position of said parts when in operation. Flg. 2 1sa perspective View of the retort. Fig. 3 is a perspec- M z5 tive view of the feeding-cartridge removed from the retort, showing our preferred mode of constructing said cartridge. Fig. 4 is an end elevation, with the outer door removed, of the inner door for closing the mouth of the retort and the preferred means for locking said door to position thereon. Fig. 5 is a section taken on the dotted line 5 5 of Fig. 4, on an enlarged scale. Fig. 6 is a horizontal section through one of the pivotal lugs m3 of 3 5 the door M and its adjacent iugm?, showing the preferred mode of constructing said lugs to admit of a lateral movement to said door in closing the mouth of the retort.

The body of the stove or furnace proper maybe constructed and put together 1n any desired manner, the mode shown consisting of a bottom plate A, side plates B, rear end plate C, and a front end plate D, the whole having a cover E, with a suitable flue-opening c therein, said parts being secured together 1n the usual manner of constructing stoves. To the front end plate are hinged the usual doors d and cl2 for inserting fuel into the grate F and for removing the ashes and cinders from beneath the latter, said grate restingupon suitable lugs cast with the frame of the furnace and provided with suitable fire-proof linings f.

The gas-generating retort is made of an outer or Iire shell and an inside shell or cartridge O. The outer shell Gr is secured within the fire-chamber of thel furnace over the grate F, and in such manner that the flames from the fuel in the grate will encircle said retort, excepting at its front or mouth 6o portion. The retort is preferably provided with an outer rib h, which engages on the outside of the front of the stove, the frontend of said retort projecting through an opening therein and resting on the body of the furnace f at the lower portion of said opening, as shown. The rear portion of the retort is preferably provided with a supporting-lug h2, which rests upon a suitable projection hcast with the rear end plate O. The mouth of the retort is closed 7o in any suitable manner, that shown being preferred, which consists of a door M, hinged to the front plate D of the stove or furnace, as shown in Fig. 4, the inner-face of said door projecting inward, as shown at fm, Fig. l, to fit the mouth of said retort. It is preferred that the inner face of the door be provided with a suitable packing of asbestus (not shown) at that point against which the outer face of the retort will impinge when the door 8o is closed, in order that said retort may be rendered gas-proof. This door M maybe locked to place against the mouth of the retort in any preferred operative manner, that shown being considered the more effectual, which consists of a lever N, fulcrumed centrally between the door M and bracket fn, the free ends of said lever being adapted to rotate and lock at the rear of the hooked lugs n2, cast with the front wall, as shown. 9o

The coal is fed or inserted within the retort G by means of a detachable shell or cartridge O. This shell at its bottom and sides fits against the outer shell and is made of metal, so as to readily transmit the heat by radiation from the outer shell to the charge in the cartridge. This cartridge O consists of a closed into the retort.

itat/i2 of cartridge is that shown, having a bodyportion with a lid P hinged thereto, the outer end portion of said lid having a [ian ge p, which overlaps the front end of the body portion, in order to retain said lid iirmly to place as the cartridge is fed into or removed from the retort. To the front end of the cartridge is secured a staple s, over Which the hasp S engages, the latter at its opposite end being loosely connected to the lid P, as shown.

To the front of the stove or furnace is hinged' a door T, which, when closed, tits over the door M, thus permitting an air-space between said doors to protect the outer one. At the bottom of door T is provided a slight airspace t, with suitable perforations t2 through the body of the stov-e near the inner top portion of said door, the object of said air-space and perforations being to carry o any gas which might for any cause escape from the retort, and thus prevent an escape of gas into the room in which the stove is located.

The retort is provided With a suitable pipe WV, tapping through the outer shell G for carrying off, purifying, and storing the gas, for which latter purpose any suitable gasometer may be employed. The operation of our improved gas-generating device is as follows: The coal is put into the cartridge O, after which the lid P is secured and locked to place by means of hasp S. The cartridge thus loaded is inserted within the retort G, after which the door M is closed and locked by means of lever N, after which the outer door T is closed over door H. The retort is now ready to generate gas, which is accomplished by means of heat applied to said retort, Which heat may be generated by any suitable fuel. After the gas has been eX- tracted from the coal Within the cartridge the former passes 0E into the retort, and from thence is carried off through pipe W to be purified and stored ready for use. To remove the coke from the retort, the doors T and M are opened, after which the operator takes 'a hooked rod, (not shown,) the hooked portion of Which is inserted Within the staples of the cartridge, and the latter `is then Withdrawn from the retort andafreshly-loaded cartridge yinserted therein. One or more cartridges may be kept loaded ready for insertion within the stationary retort, and, ifv desired, the coke may be burned in the grate when removed from the retort, thus economizing fuel. Itis preferred to connect a pipe W2, leading from pipe W to the flue Y, said pipe W2 having therein a Valve w, the latter being closed at all times, except when desired to let the gas pass off through said flue. This is desirable when a fire is first started Within the grate, as the gas first generated is not of a desirable quality forilluminating purposes. It is also desirable at certain times to permit the gas to escape from the retort before opening the mouth of the latter, in Which case the valve w is opened.

In Fig. 5 We have shown the preferred mode of securing the locking-lever N Within the bracket n, which consists of ascreW-threaded bolt n3, passed through said bracket and lever and engaging with anut n, the latter resting within a countersunk portion of said lever in a non-rotatable position. After the lever has engaged the lugs n2 on the casing the operator takes a wrench and turns the bolt a3 in the proper direction, Which causes the nut 'a4 to travel outward thereon, and with it said lever, and in this manner the door M is more securely locked to place over the mouth of the retort. In locking this door M to place over the mouth of the retort it has been found advisable to provide for aslightlateralmovement of the former, which we accomplish by `means of an enlarged or reamed portion m4,

formed in the lugs m2 m3, as shown in Fig. 6. This construction will admit of lug m3 moving slightly on the stationary lug m2, and in this manner the door M is readily accommodated to the mouth of the retort. v

The advantages of our invention are apparent, the same being simple of construction, reliable in operation, and cheap of manufacture. The closed cartridge for charging the fuel into the retort and the facility for removing the burned coke therefrom is an especially valuable feature of our invention. The cartridge being closed, no cinders or dirt can escape therefrom during the removal from the retort. The cartridge is readily loaded and inserted Within the retort. The means afforded for closing the mouth of the retort and also the means afforded for carrying off any escaping gas are also valuable features of our invention. i'

It will be observed that the cartridge O is perforated only upon its top section and that it is shaped to fit the retort and rest snugly against the sides and bottom thereof. This is important, as the coal inthe cartridge has to be highly heated. It is essential that the sides and bottom of the cartridge be in close contact With the sides and bottom-of the retort, so that the heat will be readily radiated through the cartridge-shell to the charge therein. If air passages or spaces were provided around the cartridge and retort, it Would be difficult to heat the charge to the proper degree. In this construction the 'cartridge is, in fact, a part of the retort, and it will also be observed that there is a chamber between the top of the cartridge and the top of the retort, where the gases maybe momentarily held in suspension. Another advantage is derived in the construction of the outer and inner retort or cartridge-shell. The latter may be quickly removed With the contained charge of coke, which can be dumpedhot into the fire-chamber of the furnace. Another charge, which has been previously loaded, is inserted into the retort, which is quickly closed. Thus the retort can be readily charged, the coke used hot, so that the retort will furnish enough IOO IIO

heat to generate all the gas if good ooal is emthe'niouth of the retort, and the outer door T,
