IMPROVEMENT iN FIRE-PLACE HEATERS.

Specilication forming part of Letters Patent No. 210,870, dated December 17, 1878; application iiled March 8, 1878.

To all whom it may concern Beit known that I, ALONZO RICHARDSON MORGAN, a resident ot' Astoria, Kings county, and State Oi New York, have invented new and useful Improvements in Fire-Place Heaters, of which the following is a specification:

This invention consists of improvements of the open-fire heater with expanding combustion-chamber and jacket patented by iVm. L. Phillips, Januar Y 13, 1874, whereby the same is adapted for use in mantel-openin gs, and also whereby a very simple arrangement is obtained that enables the heater to be con- `,'eniently applied to ordinary lire-places, and affords easy access for making the connectingjoint between the tire-box and the expanding chamber, to make and keep it tight, and thus prevent the escape of gases ot combustion into the air warmed, and forming the atmosphere ofthe rooms warmed by it.

Figure l is a sectional elevation of the improved fire-place hea-ter and a lire-place in which it is arranged. Fig. 2 is a front elevation, and Fig. 3 is a horizontal section, the latter being taken ou the line a a of Fig. 1.

Arepresents the open-fronted fire-box, which, in addition to the ordinary combustion-space, has an expansion-extension, D, formed in the top by the large backward projection of the back plate in the place of the usual pipe-connection, thereby considerably increasing the combustion-space, and sensibly lessening the rapid escape ofthe heat and unconsumed gases. This extension D projects into the space behind the tire-box suiliciently to connect with the reverberatory chamber E located therein, taking the place of the ordinary smoke-pipe connection., but being much more capacions at the junction at said chamber, with which it makes the connection by entering a collar, H, projecting forward from its side, which `joint may be tted gas-tight, with or without cement. The reverberatory chamber E is located in the space behind the lire-box, with its lower end a little below the extension D, so that its bottom can be reached readily through extension D, for clcanin g out the soot and ashes readily which deposit therein. lt extends upward as high or higher than the mantel, as may be desired, while the lire-box is below the mantel, and projects forward from it more or less. fit-hin chamberE is a deiiectingplate, I, to impede the too rapid es cape of the products of combustion, which said plate projects down about as low as the bottom ofthe passage from the fire-box; but said passage and the plate are both wholly above the level of the top of the front opening into the tire-box, the object of which is not to impede the escape of the products of combustion to such extent as to cause, with ordinary chimney-draft, the regurgitation of gases into the room, which is a common complaint with ordinary tire-place heaters when the doors are open. At the same time it is sought to make such hinderance to the escape as to -et- 'ect good combustion, and cause the air surrounding the heating-surfaces to be warmed as much as possible.

The cham ber E is indepei'xdent and detachable from the tire-box extension, enablin g each to be made and applied in different sizes, whereby each maybe adapted to the different areas or dimensions ot' chimneys already eX- isting or those that may be constructed specially for these heaters.

The front plate, B, and the back plate, C, of the tire-box are projected prominently forward, enabling theextension D to be formed directly over the lire-box, with its back end not entendL ing beyond the back of the lower portion of the tire-box, so that, in cases where the tireplace already constructed is so that the chamL ber E cannot be placed as high as desired without disturbing the arch F of the tire-place, it may be dropped lower down behind the lirebox, and have its collar H liXed higher upon it, but generally the arch will not prevent the placing of the chamber E as high as desired.

The connection between the extension D of the nre-box and the chamber E, which is gen erally very diiiicult to keep tight, is, in this construction, where access can always be had to it by removing the front plate or mantelframe surrounding the heater. The situation of the reverberatory chamber E is such that its interior is completely accessible through the open fire-box and extension D, and may at any time be cleaned from soot, which is not the case with other re-place heaters.

The front plate, B, in which the front openin g ofthe fire-box is made, extends directly upward a short distance above the top of the iirebox, and thence backward at B toward the front Wall of the lire-place, and terminates in a flange, J, which extends over the top and down the sides to the lire-place hearth, and serves, with the 'tlange K of the frame L, to securely connect the lire-box to the brick-work, the said frame being fastened to the latter by any suitable device.

It will be seen that this construction affords a simple and easyT method of setting up the theater by first enabling us to place the chamber E with its smoke-pipe attached in av perfectly secure position, and then to adjust perfectly the lire-box and its connection with the back chamber, and finally to place the frame L, which secures the tire-box.

The removal of the frame affords readyT access to the joint at H at any time, should the ljoint require to be repaired, thus insurin g safety against the escape of gases into the air, which is so common with other heaters, yin which greater diiculty of attending to the joint exists.

The air for heating purposes enters through the opening in the hearth at O, and, after being heated, passes up in the chimney into the rooms to be heated by passages of common arrangement. It may also enter through registers P in the front plate or in the base from the room containing the heater', if desired, and in practice dampers Will be employed to turn it on or oft either l Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The nre-box A, having a distinctivelyformed and capacious rearward extension chamber, D, at the top, instead and in place of the ordinary pipe-connection, and the reverberatory chamber E, in combination, when said extension D terminates at andunites with said reverberatory chamber and said reverberatory chamber is located with its bottom accessible through the extension D.

2. The combination of the open-fronted tirebox A, front plate B B', having flange J, and the frame L, having 'flange K, with a fire-place, substantially as described.

3. The combination of the open-fronted firebox A, having expansion-chamber D, front plate B B', having flange J, frame L, having` ange K, and the reverberatory chamber E, substantially as described.
