FIRE-PLACE.
e SPECIFICATION forming part of Letters Patent No. 423,693, dated March 18, 1890.
` Application filed May 10, 1889. Serial No. 310,213. (No model.)
To all whom it may concern:
Be it known that I, GEORG WILHELM LN- HOLDT,.of Berlin, Germany, a subject of the Emperor of Germany, have invented' certain new and useful Improvements in Heating Apparatus, of which the following is a speci-t health. In consequence of the destructive influence of the fire on parts of the grate these parts have to be made especially strong, and thereby the heat given off at these parts is considerably limited. These evils are avoided by the improvements which form the object of this invention, in which the name is drawn in downward direction into a re-proof body and so concentrated that the separate sheets of flame are thoroughly mingled with `each other and with a sufficient supply of fresh heated air, so that a complete combustion' is effected. By causing the flames to pass downward and .concentrating them in a comparatively narrow comb ustion-chamber the radiating-surfaces in stoves and the heat-absorbing surfaces in boilers that are brought in immediate contact with the flames are protected against injury by burning and the warping of parts of the stove and the opening of the joints are prevented. Even in case of faulty joining of the parts-as, for instance, in Dutch tile ovens-there is no danger from any escape of injurious carbonio-oxide gases, as they are entirely burned, together with other iinperfectly-consumed products of combustion, by the intermingling of the flames in the com. bustion-chamber, and thereby transformed into carbonicacid, which is carried od by the increased draft generated in the stove.
In the accompanying drawings a flre=place with my improvements is shown, Figure l rep-. resenting a vertical transverse section on line Fig. 2; and Fig. 2, a horizontalsection on line y y, Fig. 1.
toward the rear end or exit. The chamberal ends at the base beneath the grate-bars in a tube-shaped portion, the back pipe of which s, Fig. 2, opens out into the chimney, and which can be closed by a damper, while the front portion c of the pipe projects throughjo the front wall of the stove and is closed bya glass pane, or it may serve as an inlet for superheated air or steam into the combustionchamber, in which case it is suitably shaped for this purpose. l
VFrom the rear part of the combustion-chaml ber extends in downward direction a vertical channel e, which has an opening fr for cleaning purposes and which passes through the ash-box. To the channel e are attached cir- 8o culating-pipes q, for drawing od the combustion-gases, if desired. Over the grate-bars h is suspended the fuel-chamber t', which is made of corrugated boiler-iron, by means of which, when there is a difference of temperature between the fuel-chamber and the mantel of the stove, the latter is preserved against injurious and destructive strains by expansion. This casingz' is divided by a channel fm, formed by a hollow partition which 9o widens out toward the bottom, and the fuel is prevented from falling thereon by a saddle or delector o, for which also al tube may be substituted. j The sides of the widened part at the ends of the channel m prevent the fuel from falling into the slot b5 The stove may be heated at will, and the pipe s may be used to conduct the furnacegases direct to the chimney. The lflame pro- Y duced heats at once the walls of the combusroo tion-chamber a, and since the slot b Vis only of slight width the flames which rush from opposite directions with a powerful draft toward the flue will be forced through the said slot, so that a complete combustion is effected. This draft is further increased by drawing in the air from. above into the furnace through `openings controlled by regulating-screws in the supply-door, which will be most natural, as thereby the most direct course is provided for the products of combustion to the chimney. The result of this is that the oxide of carbonio gas generated by the decomposition of fuel in the fire-pot and fuel-chamber can-- not accumulate, but is drawn off immediately in downward direction. Further, the downward draft of air through the fuel-chamber and fire-pot, carrying with it thegases de veloped in the latter, effects a constant cooling of thev walls, and especially of the ends of the fuel-chamber, which are thus kept from vburning out, this being one of the greatest evils inthe stoves as hitherto constructed.
When the ire in the stove is thoroughly lighted", the damper may be closed in the flue a, so that the gases of lcombustion produced in the combustion-chamber a will pass through the circulating-pipes q before reaching the chimney.
Since in this arrangement of the lire-grate Y the ydames do not have any baneful influence either on the mantel of the stove lo or on the the complete combustion of the gases takes place in the slotb of the combustion-chamber 0.. The combustion-chamber a may be singleorV double walled, and in the-latter case the space between the walls .may be filled with air or liquid. There may be one or more vcombustion -chambers in the furnace. In
short, it may be varied at will in its mode of application, material, and position, so long as it answers the above obj ect. It should be kept in mind that the flames are forced downward by thev construction of the combustion-chamber and are compressed on passing through the latter. l
It is plain that with this arrangement of the grate and fire-pot they can be separated from and located at 'some distance from the heat-emitting surfaces.
The grate-bars are not necessary for carry the main object is attained. Having thus describedmy invention, I
claim as new andl desire tov secure' by Letters Patentma l. In a heating apparatus, the combination, with a fire-pot, of a combustion-chamber projecting upward from the bottom of the firef .combustion-chamber, and a delector above the top of said partition, substantially as set Iforth.
, In witness whereof I have hereunto set my hand in presence of twoV witnesses.
