GAS FIREPLAoE-HEATER.

SPECIFICATION forming part of Letters Patent I\To 758,111, dated Apri126, 1904.

Application filed February 19, 1903. Serial No. 144,030. (N0 HlOdL) l To all whom t ina/y concern:

Be it known that 1, ALBERT B. ScHorrELD, a citizen of the United States, and a resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Gas Fireplace-Heater, of which the following is a specification.

My invention relates to a gas fireplace heater, with the object in view of economizing space and utilizing to great advantage the heat from the gas-dames.

My invention contemplates the construction of a gas-heater which shall lit into the space commonly left in the Wall of the chimneyv under mantels and utilized for gas-logs and open ire, and which shall at the same time prove eminently effective in heating the air of the ing in a simple way, andwhich shall have a very attractive appearance.

A practical embodiment of my invention is represented in the accompanying drawings, Y

in whichm Figure 1 is a view of the heater in front elevation as it appears in use. Fig. 2 is a vertical section from front to rear. Fig. 3 is a horizontal section in the plane of the line A A of Fig. 2. Fig, 4 is a similar section in plane of line B B of Fig. 2, and Fig. Y5 is a view in detail of the translucent pocket. l

The casing of the heater maybe a hollow casting consisting of a back 1, sides 2 andB, a top slanting upwardly and outwardly fromthe back 1 to the front of the fireplace-opening, as indicated at 4, and then Vcontinued outwardly in a horizontal direction for a short distance, as shown at 5, and a skeleton front 6, provided with openings and floor-'support' ing lugs, as follows: At the bottom of the front there is an opening 7 the full width ofV the casing, through which air may be freely admitted' into the interior of the casing, the said opening being formed by stopping the frontat a distance above the bottom of the casing, the opening7 being shielded by means of a reticulated base-piece. 8,which extends from the side wall 2around to the side wall 3 and is spaced from the front 6. At about itsmiddle point the front 6 is provided with a depending portion-9, through which there is an opening for the reception of the gas-supply pipe 10, which may be curved downwardly, as shown at 11, within the space be- Y tween the front of the base 8 and the front 6 of the casing in convenient position to be coupled to the supply-pipe (not shown) leading up through the iloor. lWithin the casing the pipe 1() may be curved upwardly, as shown at 12, and provided with a horizontal kor T branch 13, in which gas-burners 1li may be "set, or the pipe 13 may be otherwise provided with gas-discharge-oritces in any well-known or Vapproved form for the purpose of producing a line or group of gas-dames 15 Within the casing.

For the purpose of shielding the pipe 11 wholly from view when the parts are assembled I provide the hase-piece with a non-reticulated ornamental part 16 at the front and directly opposite the pipe 11. The front is further provided with an opening 17, located above the position of the base-piece 8, and covered by a 'removable dishshaped front piece 18 offset from the front.

The front piece 18 is provided with aseries of bars 19 along its front, in the present instance the bars running vertically and representing grate-bars, while immediately behind the line of bars 19 there is located a pocket` or reservoir 20, the walls oi which4 are of translucent material for the purpose of introducing therein fragments of colored glass to represent as nearly as may be the color of live coals, or the fragments of glass inthe pocket 2O may be white or of other shade than live coals and the desired shade produced by a plate of colored translucent material separate from the pocket, as will hereinafter appear.

The translucent pocket 2O may be inserted in position from the open` rear side of the front piece 18 and may be h'eld therein by anyi well-known or approved meansfor example,y by small-screws 21 and 22, set in the bottom and top inner walls of the front piece 18 immediately to the rear of said translucent pocket-and for the purpose of' preventing liability of breaking under heat I prefer to form the translucent pocket in two or more independent sections, in the present instance two being shown, having their meeting ends i hidden at the center behind the central gratebar. The front piece 18 may further be provided to the rear of the translucent pocket 20 with a plate 23 of'colored glass to modify the color of the light shining through the material in the translucent pocket 20, as hereinabove referred to, or the said plate 23 maybe omitted entirely and the material within the translucent pocket 20 be alone relied upon to give the appearance desired. Provision. is still further made for the introduction of a plate 24 of mica to the rear of the plate 23 for the purpose of shielding the plate 23 and the translucent pocket 2O when the latter are made of fragile substance-such, for instance, as glass.

The

plates

23 and 24 may be held in position against the abutments formed on the inner wall of the front piece 18 in a manner quite similar to that shown and described with respect to the translucent pocket 20.

The front piece 18 is located opposite the iame or group of flames 15, so that the light therefrom will shine through the translucent pocket 20 and past the grate-bars 19, giving the heater the appearance of being lled with g live coals, andto intensify this light I place within'the casing to the rear of the group of flames 15 and at such an angle as to reflect the light therefrom directly towarolthe translucent pocket 20 a reflector 25 of any material suitable for the purpose--for example, white enamel sheet-iron-and this reflector is preferably continued, as shown at 26, down underneath the group of lights in order to reflect the light and heat upwardly and forwardly along the entire front of the casing.

For the purpose of gaining ready access to the burners within the casing for lighting and observing that all are lighted I provide sliding doors 28 29 at the front of the casing above the front piece 18. Y

The front piece 18 may be made removable by sliding it endwise into position in front of the opening 17 in'the front of the casing. To this endthe front piece 18 is provided at its upper and lower rear edges with flanges,(denoted by 30 and 31,) which slide in corresponding grooves formed in thefront 6. e

The casing of' he heater is divided above the `doors 28 29 by a horizontal diaphragm 32, in the present instance hinged at its rear to the back of the casing, the part below the diaphragm 32 forming, for convenience of reference, the lire-chamber of the heater and the vpart above the diaphragm forming the heating-chamber. The diaphragm 32 is provided with openings 33 therethrough for the purpose of, permitting the heat to pass from the tire-chamber into the heating-chamber, and from the heating-chamber (denoted as a whole by 34) the heatV passes out into the room through perforated screens 35 36 in the plane of the front 6 of the casing. vvThese screens35 and 36 are placed at the right and left hand of a pair of central doors 37 38, are arranged to slide into open position back of the screen portions 35 and 36 for the purpose of introducing a tea-kettle or other vessel, as shown in dotted lines in Fig. 2, for heating water or cooking, onto the diaphragm 32 and over theopenings therethrough, where it will come into intimate contact with the hot products of combustion from the group of heating-llames 15.

The casing of the heater is further provided at a point opposite the juncture of the slanting wall 4 with the horizontal wall 5 with a flange 39, which flange extends across the top and down both sides o'f the heater-casing, as indicated in dotted lines.

A facing-piece consisting of a top 40 and side branches 41 and 42 is iitted to straddle the casing of the heater in the position clearly shown in Fig. 1, and when so placed the heater may be pushed into the fireplace, as shown in Figs. 1 and 2, with the ange 39 cramping the facing-piece 40 4 1 42 between the flange and the-margin of the fireplaceopening, thus completely shutting off the opening from the room.

The upward slant of the top 4 causes the heated air to flow freely out through the screens 35 36 into the room, while the colder vair is drawn back through the reticulated base 8 and againv becomes heated, thus producing a rapid circulationand a very rapid IOO heating of the air in the room. Not only does the heat serve its purpose of heating by the circulation of the air, but the glow through the front piece 18 has the appearance of a cheerful open fire, while the removal of the doors '37 38 above the diaphragm 32 admit of utilizing the heater very advantageously for purposes of heating water and light cooking.

The 'structure as a whole is avery simple one and comparatively inexpensive.

It is obvious that changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly' tothe structure herein set forth; but
