GAS-FIRE.

T 0 all whom it may concern:

Be it known that I, WVALTER iXUDAERWIL- son, a subject of the King of Great Britain.

and Ireland, residing at Carlton WVorks,

Armley, Leeds, in the county of York, England, have invented new and useful Improvements. in or Connected with Gas-Fires, of which the following is a specification.

This invention relates to improvements in gas fires, having'for its objects among others to construct a gas fire adapted to stand on a hearth and to fit into fireplaces or well grates, and to occupy the same position as an ordinary coal fire, and to have a similar contour and appearance the gas fire being designed to have a high radiant'efliciency.

In the first place I made a number of experimentsto discover the lowest curve which a preferably well aerated flame would take when burning in proximityto a solid body; having obtained this curve applying the known attractive property a solid has for a flame in its vicinity, I next determined the increased effect of a tubular construction of a radiant or so-called fuel placed around the flame: In this manner I arrived at the lowest and longest curve at which to construct the fire to enable a flame to be directed at a curve from, first a vertical direction or nearly so, leading to the horizontal or nearly so; and to efiiciently heat up a. suitable radiant or so-called fuel to its highest efliciency.

I am aware that it has been previously proposed to construct low fires to resemble coal fires by placing so-called fuel at an angle over a flame and forcing such flame by baflies or obstructions to take an inclined course with a result that heat and products of combustion escaped and there was a con sequent loss of efliciency. In my device the flame is entirely unobstructed, being directed'in its desired course by the attractive quality of a back or solid arranged in proximity to the flame. The curve of the flame is in one direction and unbaffled.

The invention is clearly illustrated in the accompanying drawing, which, with the letters of reference marked thereon, forms a part of'this specification, and in which Figure 1 is a perspective view of a gas fire constructed .in accordance with my invention. Fig. 2 is an enlarged vertical section through the same from front to rear.

Like letters of reference indicate like parts in the difierent views.

Specification of Letters Patent.

Application filedJuly 7,1915. Serial No. 38,570.

In the disclosed form of my invention, 1 having obtained the desiredangle (which.

may vary slightly) at 'Which'to place the back B, and to which the flame will be attracted, I surround the flame or flames with a series of fire clay 'or like tubular radiants R having open-workfronts,such as R said radiants being formed to the desired curve.

The backs R of the radiants may be imperforate or substantially so. The shape bf the radiants is first in the initial directio'hof the flame and then gradually curving backward, becoming more horizontally inclined towardthe top, as shown, that is leaving a gradually tapered passage between the back and the front. The back or support B is placed behind the radiants to prevent loss of heat behind the fire, and such back is kept at a distance away from the radiants by projections or the like P formed on the back, providing a space P behind the back R to prevent loss of heat by conduction. If desired, in order to more closely imitate the appearance of a coal fire, the outer surface of the solid /portions of the open-fronted radiant-s may be colored or blackened. In

constructing the radiants any number may be formed together, and there may be two or more sets, such as upper or lower ones, as shown in Fig.- 2, joined together by suitable joint, as shown at B The pattern of the open fronts may be arranged to appear continuous, after a manner set forth. 'in the British Patent No, 16571 of 1913.

It is to be noted that the radiants are disposed in" relation to the flames in such a manner that they in no way impede or check the flame and so do-not interfere with the sufficientor complete combustion, and that correctly constructed radiants prevent escape of flame throughnth-eopen-work fronts and the said radiants becorne heated internally throughout their length} It will also be seen that only curvedfradian-ts are ar ranged in connection withan imperforate support and the use of additional cobb es or granules, such as sometimes have been heretofore used over inclined straight tubular pieces of so-called fuel to utilize escaping flames and the products of combustion, are dispensed. with.

What claimed as new is A a 1. A iu-uliantconsisting of an opera-work front and an imperforate back spaced apart, forming an unobstructed. upwardly and rearwardly curved flaei shaped first in the initial dir: scion of the flame and then to a curve to which the unobstructed flame is attracted. in a direction fro a the Vertical toward the horizontal.

A radiant consisting of an open-Work front and an imperforate back spaced apart, torming an unobstructed upwardly and rear Wa-rdly curved flue shaped first in the initial direction of the flame and then to a curve to which the unobstructed flame is attracted in a direction from the vertical toward the horizontal, said flue tapering from its lower to its upper end.

3. A gas fire, designed to resemble a coal fi.! 3,(30Zl1] 'liSl11g an upwardly and rearwardly curved radiant consisting of an open-Work front and an unperio-rate back spaced apart,

1 forming an unobstructed flue shaped first in the initial direction of the flame and then to a curve to Which the unobstructed flame is attracted in a direction from tl--. v'e"ti?al toward the horizontal, and a back support spaced from said radiant.

In testimony whereof I have signed my name to this specification in the nresence of two subscribing Witnesses.
