To all whom it nutty concern.-

Be it known that I, hTAROUS PHILLIPS, a citizen of the United States, residing at Chi cago, in the county provement in Holders for Light-Shades and Lamp-Chimneys, of which the following is a specification.

My invention relates to an improved con- The object of my invention is to provide I in the construction of such an improvement holder which shall be applicable to any of the stated purposes and aflord to the manufacturer the advantage of materially cheapening the cost of productionand to the user the advantages of facilitating the adjustment of the shade, globe, or chimney on its holder and of preventing or reducing the tendency of the holder to fracture the glass article supported by it.

In the case of the holder for shades or globes the more commonly-used generallystated construction thereof is that of an annular skeleton body stamped out of sheet metal, as brass, with an upturned circumferential flange within which to seat the shade or globe and provided at intervals with lips, usually three in number, each perforated and afiording a bearing for a set-screw, which is upset on its inner end to preventit from being screwed out of its bearing. The provision of these screws greatly increases the cost of manufacturing the holder, and their use incurs the necessity of unscrewing them to permit the shade to be seated and of screwing them against the shade to secure it in place, involving operations attended with more or less inconvenience and more or less difficulty, with a tendency to insecurity in effecting the fastening and to fracture of the glass or porcelain article by setting the screws too tightly against it. The present invention overcomes all of these objections.

In the accompanying drawings, Figure 1 is a broken view, in vertical section, showing my improvement in its preferred form asa of Cook and State of Illinois, have invented a new and useful Imglobe is confinedly seated, and it may be the gas-light shade having an inturned recessed base-flange confined on the holder; Fig. 2, a plan view of the same holder; Fig. 3, a broken perspective view of the shade represented in Fig. 1; Fig. 4, a perspective view 1 of the holder in the form of an oil-lamp i burner for retaining a lamp-chimney and in volving the same principle of construction as L the holder in Figs. 1 and 2, and Fig. 5 a l broken perspective view of a lamp-chimney having an inturned recessed base-flange adapted to be confinedly seated on the holder of Fig. 4. I A denotes the holder for a shade or globe. j Like the common holder in the class to which it belongs it may be stamped out of thin sheet metal in annular form with internal ribs a. Each rib has stamped out of it, near 1 its junction with the annular beaded rim 1), affording the seat, a lip c, which is turned l outward to extend, preferably in the claw- 1 like shape represented, over the seat I) to or 1 nearly to its outer edge. A shade B, to be l seated on the holder A, is molded with an inturned base-flange (1, containing a recess 6, l and to so seat the shade its base-flange is inj serted inclinedly underneath two of the lips c in a manner to cause the recess a to register l with the remaining lip, over which the recess passes in adjusting the shade down upon its holder-seat, and when so adjusted the shade v is given a partial turn to take the recess out of registration with each lip, whereby it bej comes securely confined on the holder against accidental displacement.

To prevent turning the shade to an undue extent in locking it in place, which might bring the recess 0 into registration with a lip, and thus prevent the confining action of the I holder, a stop f is provided on the flange d, j preferably diametrically opposite the recess, l

to enable the shade to be turned in either direction for securing it and for freeing it, 1 the stop abutting against a rib a in the path 1 to prevent the undue turning of the shade referred to.

To provide my improved construction of holder (shown at A, Fig. 4) as the burner of a portable hydrocarbon-burning lamp, formed 1 out of a stamped blank of thin sheet metal, I usually by spinning, the lips c are stamped out to extend over the seat portion 1) of the j burn er to form the rigid confining means for l the lamp-chimney B. Like the shade B, l the lampchimney is provided with an inturned flange (1, having a recess e and a stop f, and it is seated in the manner described of seating the shade.

My improved holder permits the use of shades, globes, and lamp-chimneys of the novel form representednamely, that involving the inturned recessed base-flange. This aifords a very great advantage in the way of economy in the manufacture of these glass articles by dispensing with the outwardly-turned flange, which is difficult to form, involving much labor and incurring in forming it great loss by breakage.

It is to be observed that the rigid lips c are out of pressure contact with the surface of the base-flange of the article supported by the holder. This is of importance by Way of avoiding tendency to fracture of the flange by its becoming heated before the lips ,become hot, when such contact of the colder metal with the hot glass would tend to cause the latter to break. The rigid quality of the lips is also of importance, since thereby they are caused to hold the globe, shade, or chimney unyieldingly, and thus prevent them from being dislodged. by overturning.

Other more or less slightly-modified forms of embodying my invention herein described may be devised without departure from its spirit and are intended to be included described, comprising a body of sheet metal formed With a seat for a shade, globe or chimney, and a plurality of rigid lips stamped out of a portion of said body adjacent to the seat and bentto extend thereover, and a shade, globe or chimney having an inturned baseflange provided with a recess to straddle one of said lips, said lips being disposed relatively to the seat to leave a space under said lips to admit said flange and confine it with the lips out of pressure contact with the flange-surface, and a stop on the flange to limit the extent of rotation of the shade, globe or chimney, for the purpose set forth.

MARCUS PHILLIPS.
