PORTABLE ELECTRIC LAMP Filed Ap'zil 26 1930 Y useful improvements in portable electric UNITED A STATES" ATENT orricE mm. H. R'UOKOLLB, OI STONE IO UNTAJ I', GEORGIA, ASSIGN'OB '10 GIDME'I'BAN G18 wmms, or ATLANTA, onomm ron'rum mare Lm Application fled April 88,

The invention relates to certain new and lamps. ada ted to be used either as an ordinary flas -li ht or as a pedestal lamp or lantern, to which end the lampincludes a position.

casing rovided with lateral openin adjacent .t e lam socket to permit the ateral diffusion of the light, a sleeve associated with the casing to open and close the openings at will and a special arrangement of pivoted feet carried by the rear end cap and adapted to be swung out from the body to support the lamp or to be retracted withinthe peripheral lines of the cap, when not in use.

The invention is illustrated in the accom panying drawings, in which I Fig. 1 is a side view of the lamp with'the lateral openings uncovered.

Fig. 2 is artial view, corresponding to Fig. 1, show1ng theside openings covered by the sleeve. Fig. 3 is a section on line 3-3 of Fig. 1, with the'feet' in retracted Fig. 4 is a similar view with the feet projecte in supporting relation.

Fig. 5 is a section on line 5-5 of Fig. 4.

Fig. 6 is a artial longitudinal section on line 6-6 of ig. 1.

Referring to the drawings, 1 indicates the tubular casing, which may be made of metal or any suitable plastic material and is provided at is opposite ends with the usual screw threads 4 and 15 by means of which the end caps are secured to the body ortion. The forward portion of the casin between the end and the bulb socket and re ector is provided with lateral openings 2, by excising substantially rectangular sections of the casing, which leaves the extreme end section supported by the longitudinal ribs ,3 between the openings 2.

The screw threaded end 4 of the casing is adapted to receive the cap or rim 5, which is ticularly illustrated in Fig. c. Secured within the casin to the rear of the lateral openings 2 is a b ock 10, in which is mountmo. serial Io. 447,030.

ed the usual lam'p. socket 11, which is surthe outside of the b0 y 1 and isprovided at itsforward end with a threaded flange 9 adapted to engage the screw threads 6 of the lens cap 5 and thereby lock the sleeve in closing relation with respect to the openings 2, so that the light will be directed through; the lens in a forward direction only. When the sleeve 8 has been disengaged from the lens, cap and retracted to uncover the openings 2, it will be apparent that the lamp may be used as a lantern 0r pedestal light to direct the light laterally, the rearward movement of the sleeve 8 be ing limited by a pin or stop 1 let into the casing 1.

In order to support the lamp in a vertical position, when t e same is to be used as a pedestal lamp or lantern, a series of collapsivble feet arev provided and are preferably mounted with their operating means on the rear end cap 16, which is provided with a threaded portion 17 to engage the threaded ripheral slots or notches 25 in the edge of the disk 19. Formed in the body of each of the legs 21 is an arcuate slot 24, which is en-v gaged by a stud or pin fixed in the face of the ca 16,-so that, when the disk 19 is given a partlal' rotation by means of the projecting head of the stud 20, the legs 21 will move either outwardly or inwardly, depending upon the directlon of rotation, by the en- 'ture. When the legs are simultaneously swung inwardly, by the partial rotation of gagement of the pins 26 with the slots 24.

When the legs. are moved outwardly, they afi'ord a stab e support for the lamp structhe plate 19, the outer edges of the legs conform substantially to the peripheral edge of the disk, as shown in Fig. 3, and the'angular flanges or projections 23 lie within the notches 25. i

What I claim is:

1. An electric lamp including a casing having lateral openings in its fore portion, asocketed support and reflector in said casing adjacent said openings, a lens carrying cap in threaded engagement with the front end ofthe casing, a sleeve slidable on the casing to cover and uncover the lateral'openings, a rear end cap, and foldable feet carried by said rear end cap to support the lamp.

2. An electric lamp including a casing having lateral openings in its fore portion, a socketed support and reflector in said casing adjacent said openings, a lens carrying cap in threaded engagement with the front end of the casing, a sleeve slidable on the casing to cover and uncover the lateral openings, a rear end cap, foldable feet carried by said rear end cap to support the lamp, and means for operating said feet simultaneously.

3. An electric lamp including a casing having lateral openings in its fore portion, a socketed support and reflector in said casing adjacent said openings, a lens carrying cap in threaded engagement with the front end of the casing, a sleeve slidable on the casing to cover and uncover the lateral openings, a rear end cap, a rotary plate centrally pivoted to said end cap, arcuate feet pivoted to said plate and having cam slots therein, and'pins on said cap engaging the cam slots to swing the feet to spread and folded positions respectively when said plate is rotated.

4. An electric lamp including a casing having lateral openings in its fore portion, a socketed support and reflector in said casing adjacent said openings, a lens carrying.

cap in threaded engagement with the 'front end of the casing, and a sleeve slidable on the casing to cover and uncover the lateral openings, said sleeve having a threaded end to engage the threads on the lens carrying ntestimony whereof I. afiix my signature.
