H. J. MAYNARD GLOBE BRACKETFOR INCANDESCENT LAMPS Filed Feb. 21 1922 1/ 1 M/my,

ffrom thehole 12 of the anchor 11 and the anchor thereafter lifted over the sprue 14.

of the lamp 3, and, with the globe 7 having been previously removed by unhooking, the

coinplete frame 4 may be entirely slipped iipw'ardly' from the lamp,but still in conne cted self-assembly.

{rn placing the device overa lamp re newal, thefreve se operation takesplace, and

aft-e'rjthe frame 4 has been seated downwardlyupon the neck of a lamp, as shown in Fi-gfhthe unhooked tie member 9 may bee engaged with the element 11 and rameis then lifted in operative positio' ifrea dy to receive its associated light nodifying globe or shade, by clipping the same along its upper edge 8 in the grips 5.

When it becomes desirable to apply rep flectors" or thelike to a lamp associated with'my structure, any reflector, such as 15,

shiiwn in section in Fig. 1, as afconical reflector, may he slipped downwardly over the clips 4 until it comes into engagement with the iipper portion of the hooks 5 and by reason of the frictional and resilient en gagement of the upper edge 16 of the trun-' "cated' cone shaped reflector with the three flat surfaces F of the clips 4:, the reflector will be held in operative relation to the lobe, thereby intensifying the light in the desired direction and preventing the escape or; white light, when so desired.

It will be noted that the globe 8 and reflector 15 when in operative relation enfve'lope the lamp on all its sides and one end, and provide an enveloping case for the lamp substantially conforming to the shape thereof, the reflector enveloping the lamp on all its sides from a point near the upper end of the neck of the lamp to a point substantially midway of the length of the lamp, and the globe enveloping the lamp on all its sides and its end from said midway point.- The globe and reflector bein spaced away fromthe lamp, the heat of the lamp confined in' the space formed between the exterior of the lamp and the interiors of the globe and reflector is permitted to escape mm the opening at the upper edge 16 of the reflector.

Having thus described my invention, it should be understood that there may be modifications thereof and variations therein without departing from the spirit of the invention,:or exceeding the scope of the appended claims;

hat I claim and desire to protect by Letters Patent is:

l. A light diffusing device for electric lamps, said device comprising a globe; a reflector; means comprising a band around the upper end of'the neck of the lamp and a plurality of arms secured at their upper ends to said band and extending in the line of the neck for substantially the length of the necii', the arms having means engaging the sides of the lamp at the lower end of the neck for supporting said means on the lamp and maintaining said band and the upper portions of the arms spaced away from the sides of the neck, the arms below said engaging means being bent outwardly and provided at their free ends with means for engaging the upper edge of the globe and the lower edge of the reflector for supporting the globe and reflector around the lower portion and neck of the lamp in positions spaced away from thesides of the lamp: and resilient means for retaining in engagement with the sides of the lamp, said means engaging the sides of the lamp at the lower end of the neck.

2. A light diffusing device for electric amps, said device comprising a globe; a reflector; means comprising a band around the upper end of the neck of the lamp and a plurality of arms secured at their upper ends to said band and extending in the line of the neck for substantially the length of the neck, the arms having means engaging the sides of the lamp at the lower end of the neck for supporting said means on the lamp and maintaining said band and the upper portions of the arms spaced away from the sides of the neck, the arms below said engaging means being bent outwardly and provided at their free ends with means for engaging the upper edge of the globe and the lower edge of the reflector for sup porting the globe and reflector around the lower portion and neck of the lamp in positions spaced away from the sides of the amp; resilient means for retaining in engagement with the sides of the lamp said means engaging the sides of the lamp at the lower end of the neck; and means coopcrating between said resilient means and the lower end of the lamp for preventing upward movement of said arms and band.

3. A li ht diffusing device for electric lamps an comprising a globe; a reflector; supporting means comprising a band arranged around the neck of the lamp and resilient members on said band having end portions engageable with the upper edge of the globe; means for compressing the resilient members for maintaining the end portions thereof in engagement with the upper edge of the globe; and means cooperating between the compressing means and the lower end of the lamp for preventing upward movement of said supporting means.

4. A light diffusing device for electric lamps and comprising a globe; at reflector; a band arranged around the neck of the lamp; resilient arms on said band havin shoulders about midway of their length an having grip ends engageable with the upper edge of the globe; and a helix spring ring around said arms under said shoulders; the reflector being supported at its lower edge on said grip ends adjacently to the upper edge of the globe and spaced away at its upper edge from the neck of the lamp by said band.

5. In a g'obe and reflector support for electric lamps, a globe open at its top and closed at its bottom and having an outwardly flaring upper edge, the lower portion of the lamp being received in the globe; a band loosely encircling the neck of the lamp; a plurality of spring clips attached at one of their ends to said band and having outwardly bent portions forming shoulders about midway of their length and having grips at their free ends: compressing means arranged around the clips under said shoulders for pressing the clips against the lamp to support the clips on the lamp the grips of the clips being engageable over the flaring edge of the globe for supporting the globe: a reflector arranged over said clips and engaging at its lower edge the backs of the grips of the clips for cooperating with the globe to provide a combined globe and reflector for the lamp; and means coopcrating between said compressing means and the sprue of the lamp for holding the lamp in operative relation to the combined globe and reflector.

6. In a globe and reflector support for electric lamps, a globe open at its top and closed at its bottom and having an outwardly flaring upper edge, the lower portion of the lamp being received in said globe; a band loosely encircling the neck of the lamp; a plurality of spring clips attached at one of their ends to said band and having outwardly bent portions forming shoulders about midway of their lengths and having grips at their free ends; a helix spring ring arranged around the clips under said shoulders for pressing the clips against the lamp to support the clips on the lamp the grips of the clips being engageable over the flaring edge of the globe for supporting the globe; a reflector of truncated cone shape arranged over said clips and engaging at its lower edge the backs of the grips of the clips for cooperating with the globe to provide a combined globe and reflector for the lamp; an anchorage piece engaging the sprue of the lamp; and resilient means cooperating between the sprue of the lamp and the helix spring ring for holding the lamp in operative relation to the combined globe and reflector.
