Specification forming part of Letters Patent No. 165,440. dated July 13, 1875; application filed December 22, 1874.

To all whom t may concern Be it known that I, MICHAEL FITZPAT- RICK, of the city of St.l Louis, in the county of St. Louis and State of Missouri, have invented certain new and useful Improvements in FirePlaces and Open Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, refer ence being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification.'

Figure 1 is a vertical section on line a' :v of Fig. 2. Fig. 2 is a front elevation, partly in section. Fig. 3 is a top view of the tire-place with sheet-iron hood removed. Fig. 4 is a perspective view of one side piece or jamb.

This invention relates to improvements upon the patent granted to me May 12, 1874, No. 150,680, Afor a re-place grate, a-s will be hereinafter fully described.

A A are the two side jambs, in whichopposite to each other and being right and leftare the recesses into which the upright back and the foot pieces are to be inserted, which are represented by B and C, one of them being in perspective in Fig. 4. D is a damper-plate, which has on its upper side near each end cogged racks d d and projecting stifteningbraces d d" d.

E is another dampenplate above D, as seen in Fig. 1, and which vibrates loosely1 in its recess F, which is V-shaped, and in Fig. l is seen in two positions, open andb closed; itsV purpose is to narrow the chimney-flue partially when required. G is a small shaft placed ou one side, and supported by the ends of a clamp-frame, f j", which holds the sides together. On this shaft G is a beveled gearwheel, g, which meshes into another beveled gear-wheel, g', on a shaft transverse to G, and which runs through the iire-place from outside, having on it two cogged spur-gears, d d,

` which operate upon, the racks d d on the back -of the damper-plate. H is a sheet-iron hood or smoke-stack, which is made several inches smaller than the size of chimney-flue above, and ts snugly upon the top of the jambs,

and also has an apron, h, which comes down in front as far as maybe desired to protect the face of the mantel-piece, as seen in Fig. 2 in front elevation, a part of it beingbroken away to show the lining sheet-iron H El', by

which a space, hf, is formed, so that the hot smoke in the middle is separated from the colder in the corners and sides. A wire can be attached to the upper end of the damper D, and passed through a hole in the apron h, and can be used to elevate the damper, when the geared apparatus can be dispensed with; but by the handle g on shaft G is the usual method of controlling the damper. Another plan is shown in Fig. 1, where a lever, l, is pivoted at l', and is attached to the damper, and is operated by a handle L, which comes out below t-he grate and above the fender. T he jainbs, which are held at the top in the back by the clampplatesff, are also held by through-bolts a a a aJ at the top and bottom, and at m is a rod, by which thewhole work is secured to the back wall.

The jambs A A and cross-plates B and C can be made of lire-clay, tile, or soap-stonethe jambs to be molded with recesses, as shown, for the reception of the other pieces, B and G. By the manufacture of the jambs with recesses to be adapted for the reception of the cross-pieces, with the holes for the tierods a a and the recesses on the reverse sides for the iron clamp-frame f j', the complete fire-place can be put up and be oiiered for sale as an article of manufacture, to be adapted for anyordinary nre-place in buildings already constructed, and by which their defects may be obviated and smoking 0f chimneys be prevented. The sheet-iron hood and hot-air lues may be used, if required, and iitted to such rines and chimneys; the apron serves a valuable purpose, also, of preventing the radiating heat of the coal re'from aftectin g the wood` or marble fascia. above the arch or opening.

The lining of the flue serves the purpose of dividing the ascending air and gases, so that the hotter portions in the middle will serve to create a draft above, to cause the side portions, which are colder, to he driven up much faster than if all were to be in the same flue, as heretofore. In a former patent, issued to me May 12, 1874, for a fire-place, the damper VHavingdescribedmy inven tion,whatlcla1m,

was operated by a shaft with one cogged wheel in the middle of the damper, which it is found does not operate always with ease. In the present application two racks and wheels are used, which is a great improvement over the old method; also, the hot-air ilues are placed on the sides and rear, as at k k', Fig. 2, so that heated air can be carried up the flue of the chimney by pipes k k', and into the upper rooms, and also be brought into the same room, if required.

and desire to secure by Letters Patent, is

The double smoke-flue in the sheet-iron hood, in combination with a fire-place or grate, substantially as and for the purpose described. In testimony that I claim the foregoing as my own invention, I aix my signature in presence of two witnesses. MICHAEL FITZPATRICK.
