PYRE FOR THE MANUFACTURE 0F CHARCOAL.

LSMLSS.

Application :tiled August 26, 1918.

To aZ whom it may concern:

Be it known t-hat I, Grosnrrn Baecher, a subject ofthe King of taly, residing at Florence, Italy, have invented new and useful Improvements in Pyres for the Manufacture of Charcoal, of which the following is a specification.

The pyre for the manufacture of charcoal is a continuous-action oven serving for the carbonization of w-ood.

Figure l represents a front view, partly in'section, of the arrangement of a battery comprising four p5/res. Fig. 2 also represents the plan of said battery, partly in section. There may be any number of batteries. Figs. 354 and 5 are detail views 'of one form of regulator embodying my invention.

Each battery consists in a chamber of lsuitable shape and dimensions, built of firebric'ks, of refractory material or of any other appropriate material. The lower part of the ychamber may be in the form of a hopper Z) and provided with a closing device c having a sand-bath or a bath of any other description. It is advisable for this closing device to have a valve rl for regulating the admission of air. The chamber ca contains, at convenient points, grates e and f at its top and side respectively, it is furnished with charging ports g and lt and with an aperture f communicating with the conduit for the smoke and the fumes developed by the carbonization of the wood.

At its lower part, it is advisable for the pyre to have a sub-passage Z to facilitate thedischarge of the charcoal from the chamber ctand in order to conveniently regulate the admission of the air necessary to carbonization. In the front wall of the chamber M are pierced holes vn/ furnished with appropriate lids or Stoppers to enable the observation of the internal progress of the carbonization and for the admission to the zones of carbonization of air in the quantity strictly necessary for perfect carbonization; in said' Wall there are various narrow openings /n or small low Windows for setting in position the bars of the grates e f or for removing the same in due course.

The pyro may be provided with a vapor-condensing apparatus O which may be ot' various shapes and dimensions -and furnished with a regulator p for Specification of Letters Patent.

Patented Get. 28, 1919.

Serial No. 251,400. i

As shown in Figs. 3, 4, and 5, the regulator p comprises an inner circular casing l() fixed to the vapor condenser o and provided with an opening l1. Surrounding the casing 10 is a rotatable shutter 12 formed with an opening 13 which is adapted to register with the opening ll, as shown in Fig. 4. By rotating the shutter l2 through the handle 14, the position of the opening 13 is adjusted to vary the opening ll. thus controlling the escape of smoke, as will be understood.

Having described the pyre we will now state its inode of working. At the cominencement of the operation, kindling consisting in straw, twigs or dry chips should be placed on the grate c situated above the hopper; on the top of said kindling are placed the pieces of wood to be carbonized, through the charging ports lf/ lt After the chamber a has been lled, said ports Q and /z are closed whereupon the regulator fllocated at the bottom of the hopper is opened as well as the regulator p belonging to the condenser O After this has been done, the kindling is set tire to, and when it has begun to light. the wood to be carbonized situated in the lower part of the chamber, the admission of air is lessened and regulated by means of the valve (Z the regulator p the holes 7n/ and the bars c of the grates, in such manner as to obtain the carbonization of the wood at a dark heat and not at a red heat.

Aftena certain time, the wood partially carbonized in the lower part of the chamber z decreases in volume; then fresh wood is introduced through the charging port p When the material inclosed between the two grates is completely carbonized, it may be removed. To effect this, the regulator p of the condenser 0 is closed, a vessel containing water being drawn into the sub-passage Z-. which vessel may be provided with a cage introduced into it; said vessel c may be conveyed on wheels.

After the vessel has been placed underneath the hopper b the bars of the grate are removed and the closing device c opened. The charcoal 1nclosed between the two grates c f falls into the vessel lt containing the water, it

raising the cage which held it. After this has been done with some celerity, the hopper -Z)- is re-closed and the bars of grate -e-'- replaced in position; the bars of the upper grate -fare removed. The Wood which is uppermost, partially carbonized, descends and rests on the bars of grate -e-. After this has been effected, the regulator -pof the condenser -0- is re-opened to the requisite extent, the admission of air is regulated in the usual way by means of the special regulators already indicated,

l fresh wood to be carbonized is placed in the chamber and this manner of proceeding insures the constant and continuous production of charcoal.

A similar arrangement on a conveniently reduced scale miayserve for domestic purposes, for heating and for obtaining charcoal.

Claims:

l. An apparatus for manufacturing char- `coal comprising a kiln having a plurality of chambers formed therein, a vapor Condenser above the chambers and communieating therewith, a regulator for said condenser, a pan' of grates removably fitted 1n each of said chambers and spaced apart to provide two compartments in each cham-- ber, a hopper at the bottom of each chamber, doors for closing the lower end of the hoppers, an air valver in each door, and passageways formed in the kiln below said hoppers to accommodate receptacles.

2. An apparatus for manufacturing charcoal comprising a kiln having a chamber formed therein, a condenser on the kiln, a passage formed in the kiln and connecting the chamber and condenser,a pair of superposed grates in the chamber, said grates being removable laterally from the chamber, a hopper at the lower end of the chamber, a door for the hopper, an air valve in said door, and a passageway formed in the kilnbelow the hopper for accommodating a receptacle.

In testimony whereof I have signed my name to this specification.
