SAFETY-LANTERN AND,FOOT-'WARMER. v

SPECIFICATION forming part of Letters Patent N 0. 731,024, dated June 16, 1903.

Application filed September 10, 1902. Serial No. 122,800- (No model.)

ject thereof is to provide means for support-- ing the lamp proper within the body portion or globe-frame of the same .which will permit the former to maintain an uprightposition irrespective ofthe position of said body portion or globe-frame.

lVhile a lantern in which the lamp proper will at all times maintain an upright position possesses many valuable advantages which will suggest themselvesas, for instance,

avoiding the dangers due to explosion incidentto the accidental overturning of thelanternthe improved support for the lamp referred to is primarily designed to permit the lantern to be utilized as afoot or hand warmer in addition to the usual purposes for which the same is employed; WVhen so used as a warmer, the lantern is intended to rest in a horizontal position, and as the lamp proper maintains its upright position the flame is directed toward the one side of the globe. To protect the latter and at the same time provide a heat-radiating surface, the. invention contemplates the provision of a plate designed to lie between the wick and the globe,

directly above the former when the lantern rests in ahorizontal position, and as a further protection for the globe the invention contemplates the provision of means'for automatically choking a part of the flame when the lantern is turned into said horizontal position.

The invention-also includes many subsidiary objects, which will appear as the same is better understood.

\Vhile theinvention is susceptible of various modifications, I have illustrated in the accompanying drawings what I now conceive to be the preferred embodiment of the same.

In the drawings, Figure 1 shows the complete lantern in side elevation, said lantern being shown in its upright position. Fig. 2

is ,a similar view of the lantern in its hori- Fig. 3 is a detail plan view zontal position.

of the lamp proper and carrying-frame therefor, showing the parts inthe position assumed thereby when the lantern occupies a horizontal position. Fig. 4 is a detail sectional view of the lamp proper andcarrying-frame therefor, showing the parts in the positions occupied thereby when the lantern 'is in an upright position;

The body portion or globe-frame of the lantern hereindisclosed comprises a top'a, bottom 1), and aplurality of longitudinally-extending guard-rods c, braced and strengthened by encircling rings d. The globe, which is of cylindrical form, is supported "in said frame, extends between the top a and bottom b, and constitutes a part of the body of the lantern. I

As before premised, the lamp proper is supported within the body in such a manner that the same may maintain an upright position irrespective of the position of said body. As usual, the lamp is detachably connected to the body, so that the same may be removed therefrom for the purpose of filling the font and to permit the parts to be cleaned.v

In the particular embodiment of the invention disclosed herein the lamp proper, e, is supported within a frame f, comprising a base 6 and a yoke 6 having legs rigidlysecured at their ends to the base, and a cross-bar e pref erably formed integral with the legs, connecting the upper or outer ends thereof. The fr'ameis designed to be inserted within the globe and detachably secured therein by projections g, extending from opposite sides of the base 6, which engage coacting parts of the bottom 1'). The projections g are preferably formed by the'ends of a rod soldered to the under side of the base and provided with a central loop g, forming a handle for inserting the frame in the globe and for turning the same to interlock the projections g with the coacting parts of the bottom 1). Within the frame f an oval frame 1' is pivotally supported, so that the same may rotate upon an axis coincident with the longitudinal axis of the lamp body or globe, and within said oval frame the lamp proper, c, is mounted to rotate upon an axis at right angles to the axis upon which the frame 1' is adapted to turn. The lamp proper is thus mounted to have universal movement within the lantern frame or globe. The pivotal connection between Figs. 3 and 4, formed by short studs or pins m, and like pins n are employed for pivotally connecting the lamp proper, e, to the frame t.

The pins n are, as shown, rigidly secured to the top of the font and project therefrom at diametrically opposite points, pass through the openings in the frame 4;, and are headed up exteriorly of said frame.

As before premised, the invention contemplates the employment of means for protecting the globe from the flame of the lamp and for providing a heat-radiating surface When the lantern-body rests in a horizontal position, in which position the same is turned when utilized as a warmer, and to this end a convexed circular plate 19 is fixedly supported from the yoke 6 centrally of the same, by arms p, forming extensions of said plate.

This plate, as shown, occupies a positionin close proximity to the globe and in alinement with the axis upon which the lamp directly turns, so that when the lantern-body rests in a horizontal position the flame from the lamp will play directly against the concave side of said plate.

In order to further protect the globe from the flame when the body of the lantern is in a horizontal position, a choker is provided for covering a part of the wick, this choker automatically moving into and out of action as the position of the lantern-body is changed. In the present embodiment of my invention this choker is formed by an arm 1', pivoted at one end to the bottom of the framed in substantially the plane of the longitudinal axis of the lantern-bodyto swing transversely of said axis. The arm is curved to pass around the font and is of sufficient length to reach across the wick-tube when the lamp assumes a position in which the vertical axis thereof is at right angles to the longitudinal axis of the globe. When the lantern is in an upright position, the free end of the arm a" rests against the plate p, as shown particularly in Fig. 4; but when the lantern is turned to rest upon its side said free'end falls across one edge of the wick, as shown in Figs. 2

and 3..

When the lantern is used as a warmer, it is desirable to move the carrying bail or handle .9 out of the way, and to this end said bail is slidably connected to the lamp-body, so that The construction and operation of my lantern will be readily understood upon refer-' ence to the foregoing description and accompanyin g drawings, and it will be appreciated that the parts and combinations may be varied within a wide range without departing from the spirit of the invention.

I claim- For this purpose the ends of the 1. The combination with a lantern having a lamp proper, designed to maintain an upright position irrespective'of the position of the body of said lantern, of a guard and heatradiating plate associated therewith, said plate being arranged between said lamp proper and the globe of the lantern, substantially as described.

2. The combination with a lantern-body, of a lamp proper, a carrying-frame therefor, means forsupporting said lamp proper within said frame to permit the former to have universal movement, and a plate carried by said frame arranged between said lamp proper and said globe, substantially as described.

3. The combination with a lantern-body, of a lamp pr0per, a carrying-frame therefor, means for supporting said lamp proper within said frame to permit the former to have universal movement, and a plate supported from said frame to one side of said lamp proper when the lantern-body is'in an upright position and directly above the wick-tube of said lamp proper when said body is in a horizontal position, substantially as described.

4. The combination witha lantern having a lamp proper designed to maintain an upright position irrespective of the position of said body, of a choker for the wick thereof, substantially as described.

5. The combination with a lantern-body having a lampproper designed to maintain an upright position irrespective of the position of the body thereof, of a pivoted arm I wick of said lam-p, substantially as described.

'7. The combination with a lantern-body and a lamp proper, of a carrying-frame for the latter including a frame mounted to rotate upon an axis coincident with the longitudinal axis of said body, of an arm pivotally supported from said frame to swing in a direction at right angles to the axis upon which said frame rotates, said arm having a free end designed to coact with the wick of said lamp, substantially as described.

8. The combination with a lantern designed to restin a horizontal position to provide a warmer, of a carrying-bail therefor having laterally-deflected ends bent to form eyes, said eyes engaging and being guided upon oppositely-arranged guard-bars of said lantern-frame, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
