AARON P. STORES, OF OWEGO, NEW YORK.

MANTLE-CARRIER.

Specification of Letters Patent.

Patented Feb. 11, 1913.

Application filed May 11, 1912. Serial No. 696,618.

To all whom it may concern Be it known that I, AARON P. S'ronns, a resident of Owego, in the county of Tioga and State of New York, have invented a new and useful Improvement in Mantle- Carriers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side elevation, showing in full lines the mantle carrier in raised position, and in dotted lines the same in the lowered normal position on the burner cap. Fig. 2 is a cross-section on the line IIII of Fig. 1. Fig. 3 is a vertical cross-section, and Fig. 4 is a partial horizontal section showing one of the stop prongs.

In the burning ofl of the collodion coating of incandescent mantles, the coating is quite liable to cause the lower part of the mantle to stick or become more or less cemented to the burner cap or collar at the bottom, which in normal position of the mantle is within its lower or skirt portion.

My invention is designed to overcome this difficulty and provide a cheap, simple and effective mantle support or carrier which may be adjusted vertically on the burner cap.

In the drawings, 2 represents the burner cap which may be of the ordinary type having a gauze top 3. The upper part of this sleeve is preferably provided with an annular groove 4. Frictionally engaging this cap is an annular band 5, having side extensions or arms 66 to which the ends of the wire support 7 are secured in any suitable manner, as, for example, by the tubular portions 8 illustrated. This band, which serves to carry the mantle support, is provided with upwardly projecting separated skeleton guide portions 9 of which I have shown four, though any desirable number may be used. In order to stop the upward movement of the band on the burner cap, I may employ any suitable catches. In the form shown I provide spring tongues 10, which are out out and their tips bent in, as shown in Figs. 1 and 4, these tongues engaging the groove 4. of the burner cap to limit the upward movement when the mantle is lifted.

In the 'use of the device, the cap is applied to the burner in the usual manner and before burning 0E the collodion or protective coating, the band is slid up in the position shown in full lines in Fig. 1. In this position the skirt of the mantle is above the centering cap, so that the burning of the collodion will not cause sticking thereto. After the coating is burned off, the band is slid down to the position shown in dotted lines and the burner is lighted in the ordinary way. When the band is slid down to its lower position, the guides 9 are below the top of the burner cap, as indicated in dotted lines in Fig. 1. The band or carrier may be cheaply and rapidly stamped of sheet metal, either in one or two pieces.

The advantages of my invention result from providing a burner cap with a movable mantle support or carrier arranged to move to an upper position where the mantle will not become cemented or stuck to the centering cap. Injury to the mantle is thus greatly lessened.

Many changes may be made in the form of the mantle support, the sliding parts, etc., without departing from my invention, since I consider myself the first to provide a burner cap or element with a mantle support which is movable vertically thereon to a position where the mantle skirt is above the cap.

The upwardly projecting guides 9 engage the lower. end of the mantle and hold it concentric with the burner cap, thus preventing injury to the mantle when it is lowered over the burner cap after burning ofi.

I claim:

A ring arranged to slide down over the top of a burner cap and having a mantle carrier attached thereto, said ring having upwardly extending guides arranged to center the mantle when it is lifted above the burner cap, said guides being below the top of the burner cap when the parts are in normal position, substantially as described.

In testimony whereof, I have hereunto set my hand.

AARON P. STORES.
