TUBULAR LANTERN.

Specication of Letters Patent,

Patented Aug. 12.1913.-

'Appiieatin inea December 2e, 1911. Serial No. 667,587.

To all whom I? may concern.'

Be it known 'that I, WARREN Mo- ARTHUR, Jr., a citizen of the United States` residing at Chicago, in the county of Cook and State of Illinois,.have invented a new and useful Improvement in Tubular Lanterns, of which the following is a specification.

4This invention relates to that class of tubular lanterns which are provided above the globe with a globe holder which is movable up and down in the top portion of the lantern and which when lowered upon the globe holds the latter in its normal position, and when raised releases the globe so that it canv be manipulated for giving access to the burner and for other purposes.

The object of` this invention is to produce a lantern of this general character in which a short globe is used, a globe which has the form, practically, of thelwer large lportion of an ordinary tubularlantern globe and does not contain the upper contracted portion, so that the globe holderis compara.- tively long while the globe is short and of' .comparatively largevdiameter at the top, whereby several important advantages' are secured, as willappear from the following description.

. In the accompanying drawings: Figure 1 cold blast type embodying this invention. Fig. 2 is a fragment-ary side elevation of the upper part of the lantern at right angles to F ig. 1. Fig. 3 is a horizontal section on line 3 3, Fig. 1. Fig. 4 is an elevation, partly in section, showing the globe holder raised from the globe. Fig. 5 is a side elevation, partly in section, showing the globe' holder .raised and the globe swung away from the wick tube.- Fig. 6 is a front elevation, partly in section, showing the lower rtion of the lantern in this position. Fig. gois an elevation, partly in section, of a tubular lantern havi g a dierent style of globe holder.

Like reference characters refer to like` parts in the-several figures-fv 1 Referring to Fi 1-.6, A re resents the oil pot, B the tu s, the gobe, D- the 'globe holder, and E the antern top in which 1'0 represents the usual airV chamber on the oil pot, 11 the burner withm thls chamber, 12 the wick tube and 13 the cone.

'up and the holder lowered, as

lever is turned down and the the perforated 'plate 'on whichv I plate back the wick tube is exposed and freely accessible] 16 represents guard wires which are secured to the globe plate. and

which hold 'the globe saine. Any other convenient means of so holding the globe on the plate can be employed. The globe is comparatively short and large in diameter, having approximately the shape of the lower large portion releasably -on the of an ordinary tubular lantern globe without the lupper contracted portion, so that the globe has practicallythe diameter at the top which it has at the bottom. The lower portion 17 ofthe globe'holder flares downwardly and is provided with bifurcated guides 18 by which lit is guided onV the tubes. The upper approximately straight or cylindrical portion 19 of the 'globe holder is arranged within the inner wall of the top E, which wall is separated from the outer' wall by an annular passage 20, Fig. 4, Y'through which the air enters thetubes. The up and down movement of the globe holder is best effected by a transverse lifter shaft Q1 which is journaled in bearings 22, 23, on

the tubes and providedatone cnd with a lever '24. 'This' l,shaft passes transversely thrugh the, globe holder which is provided on each side with a horizontal slot 25, Fig. 2,v and the relation of the shaft, lever and slots is such that when the lever is turned represented in Figs. 1 and 2, the shaft isadjacent to the forward end of the slot and beyond the dea d center and holds the globe holder firmly down on the globe and the latter on the globe plate and the globe plate on the air chamber, thereby holding these parts tightly against each other, while when the holder raised, lifigs. 4 and 5, the shaft is adjacent tothe rear end 'of the slot and holds the globe holder in its raised position. The lantern top Ev is provided with suitable openings 26 for the escape of the products of combustion and can be drawn out'of a single blankof sheet metal, if desired. Upon raising the globe holder from. the globe the latter and the globeplate can be VtippedbackV Loro7 15e.

tlicrefofe less liable to crack or become' broken, sind tbe globeis more easily packed for snipn'ient than an ordinary globe, The globe is so Sbort that it is possible to light the Wiclr'tlirongli the top of the globe on 'raising tbe4 bolder, which facilitates the lighting of tbe lantern in tbe Wind. The lifter mechanism connected with the globe bolder ie coolly operated because is located in n part of tbe lantern which is easily reached by the thumb of the right band holding the lantern, vand since tbe lifter is not required to litt tbe Weight of tbe globe but only that. of the bolder, tlieinoycments oi tbe bolder nre effected with little eilort.

'Elie lantern represented in Fig. T differs iiroin tbn represented in Figs. in that in Fig. l' tbe bolder is forced down by e. spring 2'? orrrngod between e shoulder on tbeL holder and vthe lantern too in e Well known manner.;- Wliile in the lantern of Figs. LG no suoli spring is employed and the holder is held down simply by tbe lifter sluit,
