0F CONNELLSVILLE, PENNSYLVANIA, A CORPORATION OF GLOBE OR SHADE AND HOLDER THEREFOR.

To all whom it may concern:

Be it known that I, I).\NIEL A. RirLnY, a citizen of the United States, a resident of Connellsville, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Globes or Shades and Holders Therefor, of which the following is a specification.

The object of the invention is to provide improved means for supporting shades or globes, particularly those used on inverted gas lamps.

The invention provides an efiicient mechanical union between the shade or globe and its supporting device, no binding screws or other movable and insecure clamping means being employed.

In the accompanying drawings, Figure 1 is a view of one form of the support, together with a globe or shade in position thereon, the parts being shown partly in front elevation and partly in section. Fig. 2 is a top plan of the assemblage shown in Fig. 1. Fig. 3 is a detail of a portion of a globe or shade illustrating its notched upper edge. Fig. 4 is a perspective of a different form of holding device from that shown in Fig. 1, and Fig. 5 is a vertical section of the same.

In the adaptation of holder or support shown in Figs. 1 and 2, the sheet-metal skirt-like cap or canopy 2 of humor structure 3 has its lower portion cut, stamped, or pressed to form the depending lips or flanges 4 and the outwardly extending overhanging flanges In an economic and desirable construction the skirt portion of the holder is cut to form the alternate downwardly and backwardly extending supporting portions 4 and the outwardly extending portions 5, said parts being sufliciently separated vertically and laterally to admit the top edge of the shade or globe.

The glass shade or globe 6 has its holesurrounding edge formed with equally spaced slots or recesses 8 sufliciently large to admit the supporting flanges or tongues 4 with edge 7 fitting up beneath flanges 5. Normally, the space between flanges 4 and 5 is slightly narrower than the thickness of the shade edge to cause the metal to spring and frictionallv bind said edge when the shade is turned to move slots or recesses 8 out of register with the supporting flanges Specification of Letters Patent.

4, as shown in Figs. 1 and 2. The shade is thus securely held and there is no danger of accidental disengagement such as is present with binding screws or other movable attaching means. Slots or recesses 8 are usually not fully covered by flanges 5 and hence assist materially in ventilating the shade or lobe.

The ho lder shown in Figs. 4 and 5 is in the form of a ring or collar, the base thereof having the cooperating lips or flanges 4 and 5 is in Figs. 1 and 2, while the upwardly extending flange or neck portion 9 is grooved or indented circumferentially at 10 to enter a burner structure 11 of usual form, being held therein by the customary binding screws 12, as shown in Fig. 5.

\Vhile the invention is designed primarily for use on inverted gas burners, Fig. 1 illustrating the depending gas pipe 13 and mantle'14, also ventilating opening 15 in cap 2, it will be understood that the improvements may be applied to electric or any other form of burner, and that its position may be either inverted or upright, as desired.

1 Although there is a trade distinction between globes and shades, those terms are, for the purposes of this case, used as synonymous.

I claim 1. The combination of a shade having a circular hole formed with edge notches, an annular sheet-metal supporting device shaped to form integral projections for entering the shade notches and other integral projections for overhanging the edge of the shade, whereby when the assembled parts are turned one relatively to the other they are securely united.

v 2. The combination of a shade or globe having notches in the edge surrounding its top hole, an annular sheet-metal supporting device flanged to overhang the top edge of the shade and also formed with flanged projections in a lower plane than the overhang; ing flanged portion for entering the shade notches, whereby when the assembled parts are turned one relatively to the other they are securely united.

3. The combination with a shade having a circular hole formed with edge notches, of a shade support provided with laterally separated projections adapted to enter the shade notches and engage the shade between the notches when the shade and support are turned one relatively to the other, the support provided with project-ions spaced from the first named projections a distance corresponding approximately to the thickness of the shade for engagingthe exterior of the latter when the parts are assembled.

4. The combination with a shade having a circular hole formed with edge notches, of a circular support provided with two series of peripheral projections, the two series separated from each other a distance corresponding approximately to the thickness of the shade, the projections of eachseries spaced apart and arranged opposite interruptions in the other series, the projections of one series adapted to enter the shade notches and engage the shade between the notches when the shade and support are turned one relatively to the other with the projections of the other series engaging the exterior of the shade.

5. The combination with a shade having a circular hole formed with edge notches, of

an annular support formed of resilient metal having integral projections spaced apart latera ly and also spaced apart verticallyto interlock with the notched edge of the shade and exert pressure on opposite surfaces of the latter.

6. The combination of a canopy of an inverted gas burner havin its lower edge provided with two series 0 projections spaced apart laterally and also spaced apart vertically, and a shadehaving a circular hole formed with notches with the lowermost projections entering the notches and engaging the shade between the notches when the canopy and shade are turned one relatively to the other with the uppermost projections engaging the exterior of the shade.

In testimony whereof I afiix my signature in presence of two witnesses.
