implication filed time It,

To (ZZZ whom it may concern:

Be it known that LCrrAuLrs i 'i ooo- VILLE, s citizen of the United States residing in the city of Chicago, county of Cook, and State of lllinois, have invented certain new and useful improvements in Portable lliights of which the following is e specification This invention relates to improvements in portable lights and refers more particulerly to s, rugged type out construction, particle lerly adapted for use in factories reilway shops, mines", garages and all typeset outside construction WOTlL l 7 Among the salient objects oi the iirveir ticn are to provide hump- ,construction which is Waterproof one which is justelole verticsll y mid in addition, as lemp which may he radian d axially so that the light may he turned in en directiose; to provide e construction iii. which the light cord is insertehle into lower pert-e oi the upper telescoping meroher, e construction which obviates the objectionable diiliculties which attend the Wear and deterioration to the insulation Where the cord is moved up and do ivte Within the edjustehle'stond; to provide friction elements, both in the lamp sockets and in the vertical steed which wit the positioning of the stand in convenient position so that the illumiuetion many he more edva-ntageously placed reletire the Work to hedone.

In the drewiugs:

'llio construction is such that the sleeve 6 is. vertically adjustable in the outer tube 3 and may be set fixedly in eny vertical position by means of the thumb screw 5. The inner rod being; fixed With the sleeve as far as vertical movement is concerned, is however axially rotatable on the top of the sleeve and on the lower s 'alit ring The tension which is imposed on the split ring by screwing; the rod 7 into the lower cap determines the friction which is produced in turning the inner rod or tube. The amount this: friction may be adjusted by turning the hearing flange 11 by hand or the nut 12 both which are fitted to the inner rod or tube C end "when turned drew the cap up closer o the sleeve, tending to draw the split rin together end increasing the hie tioii the inner sleeve end the inner rod ortulie. This arrangement of the sleeve and inner tube permits the rotating of the inner tube which holds the switch and upper lemp Without mori mg the lower stand 1 and the friction permits the positioning of the light at any desired place Without allowing it to become misplaced due to free eiriel rotetion The switch 10 may he of any common type of electrical switch which is inert-sod ine heavy waterproof easing, the lir ht cord entering; the switch through a striding loo arrangement 15. which prevents any moisture, or Water entering the switch throrm'h the cord opening? in upper goosei is screwed into an upper hipple '17.? on ti e switch 10 and is so shaped to cent;- lize or stabilize the light. This eclr: also terms-hes it convenient i moving the light from place To the ripper rtremity oi? the es: which is th ie ecrerved e, 18, Cniiiped into the t the bushing shell 20 etching hot it? end hle, it my, rreter de the tit) ll lhl Milt gooseneck and terminate in suitable connections in the socket. An electrical incandescent bulb 28 is screwed. into the light socket 21. A reflector 29 of pressed steel and having an inner reflecting surface such as porcelain, is rigidly attached to the outer casing 22 and has a front lens which is protected by means of a convex wire grating. In place of the convex wire grating, a convex lens having wire molded in the glass to reinforce it, may he used. he lens is held in the reflector by means of a water tight rim 31.

The interposition of the dish spring 2t between the outer casing and the loclznut permits the rotation of the reflector so that the light may be projected either up or down as the case requires. This rotation of the reflector in combination with the axial rotation of the supporting rod allows the light to be projected in almost any direction from a single position.

When it is desired to Work close to the floor, the stand 'may be separated by unscrewing the lower nipple of the switch from the upper extremity of the inner rod or tube 7 and unscrewing the outer tube 3 from the threaded stud 2. The internally threaded nipple 9 may then be screwed directly onto the stud of the stand 1, thereby shortening the stand to the extent of the length of the outer'sleeve 3. The portable lamp which is ruggedly constructed to be used in connection with rough work such as garage use or'mine use is particularly adapt ed to work where the light will be subjected to moisture. It will be noted that all the menace connections and light parts are made waterproof and that everyprovision has been made to prevent moisture from entering the stand. The friction elements mounted between the vertically adjustable tubes and the friction ring next to the lamp casing furnish means for quickly placing the light in any desired position. Another feature of the lamp is that it may be readily disasthe removal of the stem from the upright member.

2. A. portable electric light comprising a base, an upright member detachably afiixed thereto a stem having a lamp and reflector mounted thereon, said stern adjustable in the upright member and having electric connections independent and exterior-1y of the uprightinember, rotatable in any adjusted position, and adapted to be at-fixed to the with its removal fromv the up right member and the removal of the upright member from the base, said stem adapted to he locked against vertical displacement While being; rotatable therein.
