BURNER FOR GAS FIREPLACES OR STOVES.

SPECIFICATION forming part of Letters Patent No. 594,816, dated November 30, 1897. Application filed February 20, 1895'. Serial No. 539,106. (No model.)

To all whom it may concern:

Be it known that "I, WILLIAM G. TAYLOR, of Hulton, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Burners for Gas Fireplaces or Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation of a fireplace furnished with one of myimproved burners. Fig. 2 is a horizontal section on the line H II of Fig. 3. Fig. 3 is a vertical central section of Figs. 1 and 2, and Fig. 4 is an enlarged detail view.

Like symbols of reference indicate like parts in each.

My invention consists in certain improvements on the natural-gas burners for which I have already obtained Letters Patent Nos. 499,151 and 500,694, calculated to increase the radiation of heat therefrom and to make a better construction.

My improved gas-burners are designed to efiect a saving of gas, natural or artificial, when used as fuel for heating purposes'in open fireplaces or stoves.

My burners are constructed on the general principle of providing a chamber for the gas, the front of which shall be a plate of asbestos material preferably covered with asbestos in a fibrous or woolly condition and perforated with holes for the passage of the gas.

Referring to the drawings, a is the firefront or asbestos board of an open-face gas-- burner, behind which is a gas-chamber b, the board being perforated with a series of holes 0 of small diameter, which holes are inclined upward from the back to the front of the asbestos board. A supply-piped serves for pheric air. in rear of the asbestos fire-board there may be two or more such chambers placed side by side or one above the other and either connected together or disconnected and furnished with separate supply-pipes for fuelgas, natural or artificial. The burner is set in a fireplace, as shown, so as to provide an air-space 6 back of the burner connecting at the upper end with the chimney and at the hearth of the fireplace or below the asbestos board a with the chamber or room in which the fireplace is used, the object of which is to create a sufficient draft below the fire to carry off an y unconsumed gas without interfering materially with the radiation of heated air into the room.

So far as described the construction is the same as is shown in my patents. before referred to.

My improvements in the gas-burners above described consist in giving the fire board a curved shape in horizontal cross-section, so as not only to increase its heat-giving surface, but also to separate the flames from each other and improve its heat-radiating properties, and also in connecting the metallic cheekpieces f with the asbestos fire-board a on each side.

In the accompanying drawings, a is the curved asbestos fire-board, to which is attached the gas-chamber b by screw-bolts or otherwise. The interior distance between the back of the asbestos board and the back plate of the gas-chamber (except in very large fireplaces or furnaces) need not be over half an inch, the purpose being to furnish a passage for the gas in such a way that it will escape through the holes 0 in the asbestos board all over its surface instead of only at the lower or central portion of the board. For this reason the gas-chamber b should be curved in the same way as the asbestos board, as shown in Fig. 2, it being an important matter that the depth of the gas-chamber measured from front to back should be as nearly uniform in a horizontal direction as possible, so that the gas may when lighted present a uniform, sheet of fire all across the fire-board. The cheek-pieces f f on either side of the asbestos board a are also attachedthereto by flanging the inner edge and riveting or bolting the flange h to the board. Thus the board and cheek-pieces form a unitary construction which will stand alone and need only to be inserted in the fireplace without being permanently attached to the brickwork. The cheekpieces f f are curved, as shown in Fig. 2, the curvature being such that the outward-flaring e'dges press against the sides of the fireplace with more or less spring-pressure, and thus these cheek-pieces perform the additional function of holding the entire burner in place.

The curving outwardly of the fire-board in a horizontal direction in burners of this class, where the board extends in a general vertical direction and is heated on its front face by the contacting therewith of the flames, greatly increases the efficiency of the burner for the reason that the transverse curving of the board separates the flames issuing from the various perforations, the flames being distant from each other the hypotenuse rather than the side of a right-angled triangle. I have found by experiments that this separating of the flames and preventing them from matting and mingling with each other increases the heating capacity of the burner, as the purity of each flame is preserved, and it is for this reason that I conceived the idea of curving the board transversely, so that the flames are staggered slightly in a horizontal direction. Moreover, additional width of'fire-surface is given, as also a more attractive appearance. The cheelopieces also act more efficiently with a transversely-curved board, as the heat is radiated from the side portions of the burner directly to the cheek-pieces and by them reflected into the room.

To the upper end of the asbestos board I attach by rivets or screw-bolts a corrugated piece of metal g, (Russia sheetiron or brass is preferred,) which serves as an upward extension of the asbestos board and aids also. in the radiation of the heat. This extension of the asbestos board is useful in two ways. It maybe bent forward orbackward, as shown by dotted lines in Fig. 4, so as to decrease or increase the width of air-passage into the. chimney at the upper end of the open space of the fireplace, as may be found desirable, and it also permits of the use of an asbestos board which otherwise might not be high enough to fill the open space in a fireplace.

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

' 1'. An open-face gas-burner having a vertically-extending fire-board formed with series of gas-jet perforations, said board being arranged to be heated by the flames issuing from the perforations and being curved outwardly in horizontal cross-section to separate the flames from each other.

2. An open-face gas-burner having a vertically-extending fire-board formed with series of gas-jet perforations, said board being arranged to be heated by the flames issuing from the perforations and being curved outwardly in horizontal cross-section to separate the flames from each other, and cheek-pieces secured to the side portions of the board.

3. An open-face gas-burner having a vertically-extending fire-board formed with series of gas-jet perforations, said board having i11- candescing material on its front face' and being curved outwardly in horizontal cross-section to separate the flames from each other.

4.. An open-face gas-burner formed with series of gas-jet perforations, said perforations being parallel with each other, the board being arranged to be heated by the flames issuing from the perforations, and being curved in horizontal cross-section, so that the tips of the jets are distant from each other farther than are the bodies of the jets.

In testimony whereof I have hereunto set my hand.

WILLIAM G. TAYLOR.
