Specification forming part of Letters Patent No. 146,688, dated January O,1S74;application tiled June 13, 1873.

To all whom 'it may concern:

Be it known that I, PHILIP KLo'rz, of the city and county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Firellace Heaters 5 and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings forming part of this speciiication, in which- Figure l is a perspective view, a portion of the upper part of the stove having been broken away to reveal the construction more plainly. Fig. 2 is a vertical transverse section; Fig. 3, a bottom-plan view of the stove. Fig. 4 is a perspective view of the inner cover or hood which incloses the upper part of the magazine 5 Fig. 5, a horizontal section of the same, showing the. outer cover also in place, and the dividing partitions that keep the products of combustionin front. Fig. 6 is a perspective view of the detachable plate for the name or the proprietors trade-mark. Fig. 7 is a section through linevx m of Fig. 6, representing the manner in which the naine-plate is secured to the stove. Fig. 8 is a perspective view of the upper surface oi' the entablature, the two covers and the ring and damper having been removed. Fig. 9 is a perspective view of the ring and damper and Fig. 10 is a perspective View of the outer cover or top of the stove,

showing the door open.

Similar letters of reference in the accompanying drawings denote the same parts.

The object of this invention is to increase the front radiation ofthe stove, for the purpose of more thoroughly warming the lower apartments of the building in which it is placed. To these ends my invention consists in the several means employed for accomplishing the respective objects above stated, substantially as I will now proceed to describe.

And, first, the means for increasing the front radiation of the stove. These consist, essentially, in av novel` and peculiar construction whereby the heated currents of air, gases, and other products of combustion from the rechamber are made to pass up in the front part of the stove, and thence around to the side pipes.

The stove is constructed with the ordinary base B, lire-chamber A, entablature E, side tlues C Cf, magazinel D, faceplate F, and direct-draft ue G, capable of being closed by a damper, g, with a handle extending to the front. rlhe draft-chamber within the entab lature is directed into a front compartment, H, and a rear compartment, H', by means of two septa or vertical partitions, h h,`one in front of the ue C, and the other behind the flue C. When the direct-draft damper g is closed, the smoke and other volatile products of combustion pass directly up into the front draft-chamber, and thence to the iiue C. Diving into this iiue, they pass to theI base B, where they proceed `around the rear side ot' the ash-box in the horizontal passage I, and rise, through the flue C, into the rear compartment H', and thence escape to the smoke-Hue and the chimney; The top of the magazine is covered by a cover or hood, J, (represented in` Fig. 4,) which is fitted upon or into the project (Shown in Fig. S.) This cover is provided with an oblique y ing upper end d of the magazine.

flange, i i, adapted to come in line with the partitions 7L h', and connect them together, said partitions andan ge forming a dividing-plate, A

which separates the front from the rear draft` space. Upon a collar or flange, e, projecting upward from the upper plate of the entabla- -ture, around the upper end of the magazine, I t a ring, L, the construction of which is clearly shown in Fig. 9. rlhe ring is of greater diameter at its lower than at its upper edge. The lower edge tits upon the collar e, while the up per edge rests firmly again st the dan ge m around the lower edge of the opening M, and against the side iianges t' i, above described. The upper edge of the ring comes on a line with the horizontal part of the door-ange m, and inside of the ring the anges t' i are enlarged, so as to completely ll the space between the enlarged part ofthe ring and the wall of the cap J, and thereby prevent the smoke, dto., from passing through the ring from the front space H to the'rear space H. A collar, K,

cast upon the upper plate of the entablature,

forms a portion of the direct-draft ilue, and the height of this collar is so adjusted inthe manufacture that it will be covered by a projectin g horizontal flange, l, formed on the rear edge ot the ring L, as shown in Figi, and more clearly in Fig. 9. The damper g is arranged upon the iange l, being properly pivoted or hinged thereto, and the handle of thel damper may be held and guided by a lug on the side of the ring, as clearly shown in said Fig. E). The cap J having been placed upon the top of the magazine, and thering L secured in position around it, With the damper. g resting on the collar K, I next place around the projecting upper end of the cap J an outside cap or cover, N, the shape and construction of which are clearly shown in Fig. l0.

The lower edge of this outer cover or stovetop iits closely upon the upper edge of the ring L, and the cap or top its tightly against the door-liange m, and against the side and top flange i' A door, M, is attached to the outer cover or stove-top, and closes tightly upon the iiange m. The door is itself provided With a top iiange, m', which, when the door is closed, supplements the flange m, and prevents any upward draft through the magazine. The rear side of the top N projects over, so as to cover and inclose, the damper g, and is provided with an opening, upon which the smoke-pipe can be properly fitted.

By the construction above described, it willv be observed that the draft-space H is continued from the chamber Within the entablature, up inside of the ring L, and the outer cap N, around all that portion of the inner cap J which lies in front of the iiange i, so that, when the direct-draft damper is closed, the volatile products and residuums of combustion pass through the holes 0 0, directly up into said space, and circulate over and around the Whole front portion of the stove-top, Where a large amount of heat is given off by them before they enter the diving-flue C. The

heat thus given oii", being on the front side of y the stove, is radiated directly into the lower compartments of the house, where itis most needed. The products of combustion7 after passing around through'the flues C I G', emerge into the rear draft-'space H', and thence into the space around and over the rear side of the pa-rt J, Where nearly all their remaining heat is radiated through t-he thin sheet metal into the hot airspace around the rear side of the stove, whence it passes either to the lower or upper compartments of the house, according' to the condition of the hot-air registers and dampers. y

Having thus described my invention, what I claim is 1. A lire-place base-burning stove in which the products of combustion `circulate freely .around the front portion only of the stove before they enter the diving-fine C', substantially as described, for the purpose specified.

2. A iire-place base-burning stove having an entablature and side iiues, and a cylindrical top projecting above the entablature, said top being constructed with an outer and inner Wall, and having the space between said Walls divided into a front and rear compartment,V

and being arranged, with relation to the other parts of the stove, so that `the volatile products of combustion circulate freely through the'i'ront compartment, around and over the front part of the inner Wall, before entering the diving-nue, and freely through the rear compartment, 'around and over the back part of the inner Wall, after they complete the circuit of the indirect draft, substantially as described, for the purpose specified.

3. In a fire-place base-burning stove, the combination of the inner cap or top J, the ring L, and the jacket or outer top N, substantially as described, for the purpose set forth.

PHILIP KLOTZ.
