GAS-FURNACE.

- Specification of Letters Patent.

Patented Nov. 2, 1915.

Application filed November 25, 1914 Serial No. 873,992. I

To all whom it may concern: I

Be it known that I, JAMEs B. DOYLE, a citizen of the United States of'America, and

resident of Hamilton,- in the. county of Wentworth and Province of'Ontario, Can- .ada, have invented new and useful Improvements in Gas-Furnaces, of which the following is a'specifieation;

My invention relates to improvements in gas furnaces, in which a centrally located gas pipe extends through a common fire grate, a sheet metal plate thereon and through a layer of ashes on said plate. A hollow pyramid of pieces of fire-brick is placed on the ashes, and ignited gas from the upper end of said pipe, flares out into the hollow of the pyramid, thereby heating the same, more or less, according. to the regulation of the quantity of gas through the pipe. The pyramid referred to heats the inner fire-box or dome of thefurnace, and is applicable to various shapes and makes of gas heating furnaces, also to boilers, stoves and the like.

The objects of my, invention are, first, to provide means whereby a furnace may be heated in the place designed to contain the heat; second, to provide means which shall be conducive to keeping the lower portion the furnace comparatively cool, and to prevent the fire grate from warping, third, to afford facilities for obtainingand retaining a maximum degree of heat with a minimum supplyof gas; and fourth, to apply my invention to hot water furnaces, as well as to hot air furnaces, and other heating devices. I attain these objects by the device illustrated in the accompanying drawing, in which is shown an elevation of a common heating furnace having a grate and fire box in the heating dome thereof, and a portion of the casing of the furnace broken away to show my improved device and method of economic heating in the interior of the dome and the casing, both of whichare partially in section.

Similar characters of reference refer to similar parts throughout the drawing.

In the drawing, A, is the gas heating furnace, which comprises an outer shell or casing B, an inner fire box, or dome C, an entrance D through the casing to the interior of the dome and to. the fire grate E. These several indicated parts are not new, and may be of various shapes, designs and sizes, especially the grate E, which maybe of any veyin g two arrows.

desired shape and construction, rigid, rotary or otherwise, and is not absolutely necessary to the working of myinvention. The grate E being in position in the furnace, merely to show how my device may be applied to a heating furnace already supplied with a grate, and when my said device is removed therefrom, coalmay be used on the grate, as a coal burning heating furnace.

For gas burning, 2, is a round light metal- 110 and horizontal plate, preferably tin plate,

or other material, though I have satisfactorily used light card-board and in a well heated furnace. The plate 2 rests on the grate E, ormayrest on an annular shoulder or ledge 3, of the fire box, and is stationary. The plate has a round hole therethrough and concentric therewith, and the gas conipe 4, extends a distance through said ho e, and the opposite and lower end part of the said pipe extends through the casmg B and is supplied with a common gas mixer 5, whlch is provided with a common gas regulator 6.

8, is a layer of ashes, or other "material ashes -8, completely cover the plate 2,"and

are in close proximity to the perimeter of the gas pipe 4, and serve to make the plate airltight andkeep the same comparatively coo 9, is a hollow pyramid of broken firebrick', on the ashes 8, and is loosely built, the broken parts being placed one upon the other without any regard to fitting, and without mortar or cement of any nature, so that gas may permeate and percolate through and between some of said parts 9, into the dome C and through the common gas outlet fine 10, which is provided with an ordinary damper 12, to be used at discretion.

The upper end of the vertical gas inlet pipe 4, flares inwardly, as shown, to cause the gas to issue in a widely diverging jet, by reason of the smaller openin produced at the top of the pipe, and a si e distribution of the lighted gas into the hollow, or cavity 13, of the pyramid, and indicated by The pyramid'may be heated to a red hot heat, by the lighted gas, consequently the dome C is heated, thereby heat 15 are the usual hot air conveying pipes which communicate with the upper part of the space area 14, to convey warm air therefrom.

It will be noticed that the plate 2, the layer of ashes 8,'together with the hollow pyramid 9, may be applied to a heater with or without a grate E, and in lieu of an annular ledge 33, any device may be applied .10, and the outlet of hot air through the pipes 15, are all indicated by arrows.

What I claim as my invention and desire to secure by Letters Patent, is

In a gas heating furnace of the character described, a round plate having a hole there-- through and concentric therewith, rigidly located in the furnace, and supported thereby, a, layer of ashes on' and covering said p ate, a hollow pyramid of broken irregular pieces of fire-brick, loosely compiled, restingon the ashes, and extending above said hole, a gas inlet pipe extending through said hole and ashes, .and terminating in the hollow of the pyramid, the upper end of said pipe fiaringinwardly at an obtuse angle with the pipe to spread the flame of gas in every direction in the pyramid, and thereby equalize the heating of the same. JAMES B. DOYLE.
