To all whom it 'may concern.' j

Be itl known that I, THOMAS J. LrrLn, J r., of lVoodbury, Gloucester county, New J ersey,l have invented a newl and useful Globe-Holding Device for Lamps, of which the followingis a full, clear, and exact description, reference being to the accolnpanying drawings, 'forming part. of this specification, in which- Figure 1 is a vertical section partly in side.

elevation showing a. lamp embodying one foi-1n of my invention; Fig. 2 1s a top plan with the globe in place; Fig. 3 is a detail view of the ring of Fig. 2; Fig. -1 is a View similar to Fig. 3 showing a modified for'ln; Fig.- 5 is aview similar to Fig. A1 showing another form of the invention; Fig. 6 is a cross-section on the line vSTI-VI of' Fig.l 5; und Fig. 7 is a detail view of the spring cano device of Figs. 5 und v j My inventionrelates to globe-holding de vices for gas lamps, particularly lamps of the inverted type. It 1s designed to provide simple and effect-ive mechanism for holding.V

theglobe in position and for improving the In the form of Fi'gs. 1 oo-4, inclusive', 2 represents the lain casing; 3 the mixer tube; 4 the mantle shown 1n dotted lines) 5 en. inner globe; and (i an outer globe or shade. In'this form `the inner 'globe 5 'is supported upon alinetolrin v?, theedge portion of. whi lfis prefere ly looked or 'clamped inthe between the upper portion 2 and the' oever portion?L 'of the lamp casing, assho` n a'tS in Figl. g The' ring -is preferably) crved". downwardly. 'and inwardly frointhis Sommand s'p'rovid'ed with a ,series of holes-9 toellow entrance-of air. Vforcoolingof'the ring.v :These holes also w 4provide `for 'better upward' draft offvai'r prevent' accidental side movement-'ofA the ,nibs orprojections 13 of the inner globe into lline with the slots. In forming :the ring, I

alsexpreferably .provide V:guiding strips' or projectionswhi'ch contaet-withf'the. sides `forint e glo: has lower. airholes 21@ of the globe and serve to prevent its tilting or rocking. Side movements of the inner globe are liable to Causeit. to contact with. the mantle and injure or destroy it, and. such 'movements are hindered or prevented by these guiding extensions. In Fig. 3 the guide is shown as extending upwardly, While in the forni otFigjLl the extension 14a projects downwardly. This projection or guide is at the inner edge of the ring ilange, so that it its .against the globe as shown at the left-hand portion of Fig. 1. In placing the inner .globe in position, its nibs are brought into line with the ring slots, the globe is then'pushed upwardly until the nibs rise over the guard projections 12, and the globe is Vthen dropped with its Anibs inthe position shown in. F-ig. 2. The globe is then supported by its nibs, resting on the ring between the guard projections, which pre Vvinitits accidentel rotation into line Where the nibs would drop through the1 slots. In this form, I show the outer globe -6 as supported upon a 'suitable metal member or neck; 15 held by set screws 16 within the 'lower casing section.

In the form of Figs. 5, 6 andI-I' show the invent-ion" as applied to e lamphaVing a single globe twith a closed lower end.

,In this form the ring 'l is shown as prei- .vided with a shallow outer flange secured within a. beaded portion 17 ofthe eesingb.;v

while the convex portion 'of the globe rests against' the lower Vedge portion ofthe casing.

In this form I show the ring esagein pro-- vided'with the airholes 9%,.and having'two slots 11* through which the nibs' 13 of the globe may be pushed up and then-swung sidewise. In this case the guiding .projectionv which prevents side swin ing-of the globe is' marked 14.-

tions or Vcorrugations 19. These 'cms are Vengaged by the nib's oftheglobef'so that'. ls` `.the globe is turned it' lfidesalongfthe 'cerny In this o1-.1n 'I also show a spring camdevice lhavijng and is `firmly `drawn up against' theilo'werf edge of the .casing. Inft'hegform`sliown, 1'
