CHIMNEY non INoANnns'oE'NT BURNERS.

Application filed February 10, 1914.

To all whom it may concern:

Be it known that I, AARON P. SToRRs, a citizen of the United States, residing in the village of Owego, county of Tioga, and State of New York, have invented a certain new and useful Chimney for Incandescent Burners, of which the following is a specification.

The object I have in view is the production of an improved means for attaching a gas mantle to a mica chimney. I

This invention is of the same type as that forming the subject-matter of my Patent 1,066,060, granted July 1,1913.

By my invention, I seek to simplify the attachment, and to make the parts of the device capable of being assembled with great ease.

A further object is to avoid the necessity of a separate fastening means.

These and further objects will appear from the following specification and accompanying drawings, considered together or separately.

In the drawings, Figure 1 is a plan view of a chimney embodying my invention, in place upon a mantle ring, the latter being shown in connection with a burner tip which is drawn in section. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a plan view of the upper part of the chimney, showing the position of the parts, before the attachment of the chimney to the mantle ring. Fig. 4: is a sectional View on the line of Fig. 3. Fig. 5 is a cross-section, of the metal band, at the top of the chimney, before the flaps are bent to final position. Fig. 6 is a perspective view of one of the tubular extensions used in connection with the mantle ring illustrated in Fig. 1. Fig. 7 is a plan view of a modification; and Fig. 8 is a section on'the line 8-8 of Fig. 7

, In, all of theviews, like parts are designated by the same reference characters.

Referring to the drawing, 1 represents a chimney which is formed. of transparent material, preferably mica. I preferto make the chimney of several sheetsv of mica to reduce cost. The number of sheets that ,is used is immaterial. The bottom of the chimhey is bound with a metal protecting casing, and may have a mica or wire gauze bottom sheet, as shown, for the purposeof inclosing the burner and collecting the deposits Specification of Letters Patent.

from the mantle and burner. The usual ventilating openings are shown near the bottom of the chimney, together with an opening in the center of the bottom sheet for the introduction of the igniting flame from the pilot light.

The details shown and just described, are for purposes of illustration, of a particular embodiment of the invention.

make no claim herein to the particular form of chimney just described.

.The upper part of the chimney is provided with a metal band 2, which carries means for attaching the mantle to the chimney. The details of this band will be described later. The burner tip 3 shown, is of the usual form and carries the usual mantle ring 4:, and inverted mantle 5. The common form of mantle ring illustrated is provided with a plurality of integral elbows 6 and fingers 7 which are adapted to engage with and be supported by lugs (not shown) on the burner tip 3. The elbows 6, according to my invention, are utilized to engage with and support the chimney 1. The chimney with the mantle and mantle ring are preferably combined, and in such condition they may be sold together and thereby constitute an article of manufacture.

The combination of the chimney, mantle and ring may be easily attachedto the burner tip by passing the ring around the burner tip and giving the chimney apartial turn, so as to lock the fingers 7 with the usual lugs on the burner tip .(notshown). This may be accomplished by an unskilled person without need of touching the mantle. In order to readily turn the mantle ring so as to lock on the burner tip, it is necessarythat the mantle ring be properly secured to the chimney so that the ring may be rotated on the burner tip and that the ring will be properly secured to the chimney. It is also desirable that the mantle ring may be readily removed from the chimney, and another ring with. a fresh mantle substituted. This is all easily accomplished by the following mechanism. According to the preferred form of my invention, I providetubular extensions 9 (see Fig. 6) for the elbows 6, 6. Each of these is preferably made of sheet metal ofsuch a size thatit snugly fitsaround the elbow 6. .These extensions are of such a length that when in bows 6 long enough to directly engage chimneys of standard size or even larger. Each notch is provided with a side flap 1.1, adapted to engage with the side of the tubular extension which is in the notch. It is also provided with an end flap 12, adapted to lie beyond the end of the extension. and hold the latter against horizontaldisplacement.

Fig. 5 shows the best way of making the notches and flaps. Two cuts are made in the proper place on the metal band, said cuts being angular-1y arranged, as shown. The place between the cuts constitutes the end flap 12. The apex of this flap is squared, as shown, so that there will not be a sharp point which would otherwise injure the finger of the person applying the mantle ring in place. One side of the notch is bent outward, as shown in Figs. 3 and 4, and this constitutes the side flap 11. Either side of the notch may be chosen to be bent out,

' if desired. Both sides may be bent out if desired, but I find that only one is necessary to produce an opening wide enough to permit introduction of the end of the elbow or of the extension. The end flaps are bent out at the base, and then up, a short distance above the base. This is well shown in Fig. 4. The perimeter of the end flaps is slightly greater than the perimeter of the tubular extensions 9, when the latter are in place on the arm 6. The notches 10 are, of course, located upon the band 2 in proper position, so that when the extensions are placed upon the elbows 6, 6, 6, the said extensions may be simultaneously seated within all of the notches in the band. When seated, the ends of the extensions will come into engagement with the end flaps. The side flaps 11 are then bent to the original position. When this is done, they thereby inclose the upper parts of the notches 10, and keep the extensions 9 in place in the notches. The material forming the band 2 is suliiciently ductile to permit the side flaps to be bent outward and inward a number of times, so that the mantle ring may be removed and a new one substituted as many times as is necessary, whenever the mantles require renewing.

The tubular extensions 9, 9 are desirable where a mantle ring with arms of the usual length are employed. Figs. 7 and 8 illustrate a mantle ring with elbows'of sufficient length to engage with the chimney, without the necessity of the employment of the extensions.

According to my invention, as hereinbefore described, the elbows on the mantle ring, or the elbows alone, provided they be sufliciently long, constitutes arms which en- Page with the chimney.

In accordance with the provisions of the patent statutes, I have described the principle of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that the invention may be carried out in other ways.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:-

1. A chimney with notches on its upper edge, in combination with a mantle ring, means carried by the ring, which engage with the notches, whereby the chimney will be supported.

2. A chimney and a mantle ring, said chimney having notches in its upper edge, means carried by the ring for engaging with the notches and means for closing the notches, whereby the chimney will be supported.
