IGNITER FOR OIL-'STOVES- SPECIFICATION forming part of Letters Patent No. 757,703, dated April 19, 1904.
Application filed July 26, 1902 Serial No. 117,096- (No model.) v
To all whom it may concern.-
Be it known that I, WILLIAM H. VVILDER, a V
citizen of the United States, residing at Gardner, I'Vorcester county, Massachusetts, have invented certain new and useful Improvements in Igniters for Oil-Stoves, of which the following is a specification.
My invention relates to igniting mediums for use with what are known as wickless blue-flame oil-stoves. These stoves comprise an annular burner-bowl of trough form, and the oil is allowed to flow into the same, its height therein being adjusted by the raising and lowering of the burner or reservoir or by the manipulation of a valve controlling the rise of the oil in the burner. In order to start the flame, it is necessary to have an igniting medium or what is known as a kindler, and it is usual to have inserted in the bowl a strip of asbestos which projects sufficiently to be ignited, and this causes vaporization from the surface of the oil, after which 'the combustion continues by the production of the gases due to the vaporization.
My present invention relates to this igniting medium or kindler, and I have aimed to produce an igniter having a thickened upper part, 'so as to increase the igniting-surface, and a lower part of less thickness, so as to reduce the limited capillary power which igniting mediums of this material have, as it will he understood that the method of operating stoves of this class is to flood the burner for igniting purposes and not to depend upon the capillary power of the medium.
In the drawings, Figure 1 shows the burnerbowl with the medium in place.
Fig. 2- is a sectional view of my improved igniter, enlarged. Figs. 3 and I are modificatlons, en-
larged.
In carrying, out my invention I take first a wide strip A of a mineral substance, as thin asbestos, of suflicient depth to extend from the bottom to the top of the burner-bowl and of a length equal to double the circumference of the burner-bowl, so as to make a double thickness to be inserted within the burnerbowl. Within the folds of the wide strip A, I insert a series, preferably three, narrow strips B of a length equal to thecircumference of the bowl, thus making the igniter to consist of two outer folds of the wide portion A of the igniter and preferably three thicknesses of the narrow portion B. I prefer to locate the narrow strips at the upper end of the igniter, thus increasing the igniting-surface.
In Fig. 3 I have shown a modification wherein I omit the, central narrow strip and in its place use a strip of sheet metal, preferably perforated, as shown at C, extending slightly below the narrow strips of asbestos.
In Fig. 4 I show another modification, in
which I use between the outer wide layers and inner narrow layers other strips of perforated metal D.
What I claim is 1. An igniting medium for oil-stoves, composed of a multiple thickness of incombustible absorbent material of varying widths.
2. An igniting medium for oil-stoves com posed of a multiple thickness of incombustible absorbent material of varying widths, the narrow portions being intermediate of the wide portions, substantially as described.
3. An igniting medium for oil-stoves comprising a multiple thickness of absorbent material Varying in width, the narrow portion extending from the top downwardly.
4:. An igniting medium for oil-stoves composed of an elongated strip wound upon itself and a strip of less width folded within the same.
In testimony whereof I afiix my signature in presenceof two witnesses.
WILLIAM H. WILDER.
