LAMP-CHIMNEY.

SPECIFICATION forming part of Letters Patent N0. 792,473, dated June 13, 1905.

Application filed February 1, 1904. Serial No. 191,449.

To all whmn it may concern.-

- Be it known that I, AARON P. STORES, a citizen of the United States, residing in Owego, in the county of Tioga and State of New York, have invented a certain new and useful Improvement in Lamp-Chimneys, of which the following is a description.

The present invention relates to improvements in lamp-chimneys for use in connection with incandescent gas-burners, but particularly of that type in which the air is admitted to the outside of the mantle through openings in the chimney, although the invention is not limited to chimneys of that character.

The main object of my invention is to produce a chimney, preferably, though not necessarily, of mica, which will have combined with it the burner-cap and a support for the mantle, the whole being arranged to form a new article of manufacture which will be an entirety and can be sold ready with the mantle in place for direct attachment to the burner. A further object is to provide means for supporting the mantle without the need of the side rod heretofore used.

. A further object is to provide means for supporting the mantle within the chimney so securely that it will not be deranged in transportation.

In carrying out my invention I provide a chimney ofa transparent material with a base-plate upon which a projection is carried, which may constitute a burner-cap and which extends into the chimney and serves as a support for the lower extremity of the mantle.

The upper end of the mantle is carried by a removable crossbar, so that the mantle may be removed and a fresh one substituted. The chimney, with the projection and mantle, may be readily attached to the commercial form of burner by the removal of the cap from the latter, the chimney with the mantle taking its place and being supported thereby without engagement with the gallery.

The chimney is preferably made of mica panels perforated near the bottom for the admission of air to the outside of the mantle and supported upon a metal base-plate which has a central opening adapted to surround the burner. This central opening connects with l a cylindrical projection,which serves as a support for the lower end of the mantle, and carries the upper gauze, thereby forming a burner-cap. At the upper part of the mica chimney is arranged a cross-bar of some metal not readily affected by heat. The bar is formed at its center with a loop, from which the mantle is supported. The ends of the cross-bar are preferably flattened and shouldered and engage Within rectangular openings formed within a band which forms the upper edge of the chimney, whereby the flattened ends prevent the rod from turning and the shoulders prevent it from being displaced longitudinally. A removable extension, of metal or mica, fitting within the upper part of the chimney may be provided as a finish to the chimney and to increase the draft, and this extension may be provided with inclined slots, which will engage with the cross -bar and upon the extension being partially rotated will cause it to engage with the sides of the rectangular openings and will lock it firmly in place.

In order to better understand the nature of the invention, attention is directed to the accompanying drawings, showing one embodiment of the invention, and in which- Figure 1 represents a side perspective view of a chimney in place upon a burner of Wellknown design. Fig. 2 is a perspective view of the upper band and extension, the two being separated. Fig. 3 is a top view of the chimney with the extension removed. Fig. 4 is a sectional View of the lower portion of the chimney; and Fig. 5 is a view of the upper part of the chimney, showing a modified Way of supporting the cross-bar.

Inall of the several views like parts are designated by the same reference-numerals.

As shown in Fig. 1, the chimney consists of a number of panels 1, of mica, constituting the transparent portion, bent to the shape shown and secured in position by uprights 2 and to a base 3 and an upper band 1. The mode of securing the mica panels to the uprights 2 and the character of the uprights are described and illustrated in my Patent No. 700,991, of May 27, 1902.

The base 3 (shown in section in Fig.4) is upper portion is drawninward? at 8 and serves as a support for the upper gauze 9, which is inserted from below and is secured in position by elastic engagement with the sides oitheprojection7. Additionalmeans, however,

may be used to retain the gauze inposition. The lower gauze is carried by the burner, as is well understood. same shape and size as the burner-cap and, together with the gauze; w hen used may take the place of the cap.

the projection depending uponthe character of the burner used; mica panels 1 may be protected by alower band 10, which will rest within the flange 5* of the base; but this band is not absolutely essential, as the panels may be in direct engagement with the flange. The uprights 2* are provided With tongues 11-, whicharepreterably integral and which pass through openings 12in the base. These tongues beingbent up; as shown in Fig. 4', serve as a locking means for securing the base to the rest of the structure.

The lower end of the mantle 13 surrounds the projection 7, and its upper end is supported'i rom the middle of the cross-bar 14L, the ends or" which are supported by the chimney. This cross-bar takes the place of the usual side'rod carried by the burner-cap. Thesid 'e rod in burners of the type in which the present invention is especially applicable beingclose to the mantle is-subject to great heat and may become distorted or destroyed thereby.

As shown in Fig. 2, the upper band 4 ispro vid'ed with oppositely-arranged openings 1 5, withinwhich the extremities of the cross-bar 14 rest. The bar is formed of a round' rod or wire witlr the ends flattened at 16, forming shoulders 16, andthe openings 1='5- are preferably of rectangular sl1a-pe,so that thebar will not turn but this construction'is not necessary. The openings are of less width-thanthe shoulders 16, whicha'but against the inner surfaces of the upper ring 4 and prevent horizontal displacement of the cross-bar.

As shown in Fig. 5, the cross-bar may pass through openings formed directly in the mica panels, each opening being provided, it desired, with an eyelet 17.

the cross-bar is not necessarily flattened; but theshould'ers 16 may be formed by upsetting-- the wire near each extremity.

The cross bar 14 is preferably made of nickel or some other heat-resisting material and is formed near its centerwitha double The projection 7 is the The projection 7 it isto be understood, is so proportioned as to make a close fit with the burner, the size of The lower edges of the In the modification 1 loop 18 for the purpose of supporting the mantle. The peculiar mounting of the crossba'rand the provision of the latterwith a central loop is to securely hold the mantle in place; irrespective of the position it may assume. The shape of the loop is shown in Fig. 3 there being sufiicient space left between the turns of the loop to permit the supporting-loop of the mantle to be slipped within thewire loop.

The extension 19 is preferably made of some light sheet metal-,.such as aluminium, or of sections of mica and is of the proper size 1 to readily enter the ring 4:, a flange 2O serving to support the extension. Two inclined or' the extension are adapted to engage with the ends of thecross-barl i and upon the extenthe cross bar'i-n' position. Suitable clips-'22,

By

When thus assembled thechim neys, with the mantles therein, may be placed within boxesor otherwise packed and shipped, the purchaser merely having to attach the entire device to the burner in place of the burner-tip-without having to handle the man'- 1 tie directly.

it is to be understood that the chimney is 5 supported entirely from the burner 24 by enjgagement oithe projection 7 therewith and without engagementwith the gallery.

If a mantle isto'be' replaced, the used one vserted.

It is to be understood that the chimney -may be made of glass, it desired, and that ted without departing from the invention.
