Serial No. 253,282.v

This invention relates to electric lamp fixtures in general and more particularly to a therapeutic lamp fixture. v

Therapeutic lamps are often desired to be f used in a position which isnot only remote from the Anormal position ofthe lamp but which would, in the ordinary yform of lamp, require the lamp to be either removedV from its base or the base removed'froin the floor and the standard supported by some `temporary and auxiliary means. o A l j z It is the primaryobject of this invention V'to 'provide a construction whereby the lamp may be conveniently adjusted to a practically un-` limited number of positions without necessitating` the removal of the lamp from itsbase or the removal of the basey of the lamp from the floor. f l f f It is also an object of thisvinventi'on toprovide a lamp of the above type and supporting means therefor which is convenient to manufacture and to adjust. f .f

It is further an object of this invention to provide in` connection witha lampk of the above type a sectional standard therefor in'- cluding an adjustable joint for a pair of the sections which 1s provided with a large clamping surface. f y y It is also an object of this invention topro-l vide a lamp of the above character having a sectional standard anda joint for a pair of the sections in which one section is telescopic with respect to another section and a clamp for adjustably securing the two sections to-V v gether without defacing the stem of the former section. f

Other and further objects ofthis invention Vwill be apparent as the same becomes better understood from an examination of the specilication and claims in connection with the accompanying drawings wherein ,l

Fig.y 1 is a fragmentary side elevational view of a lamp embodying this invention,

Fig-2 is a fragmentary view partly in section of the saine, l

Fig. 3 is an enlarged section talenfat the line 3-3 of Fig. 2,

Fig. 4 is an enlarged fragmentary sectional view ofV a part of the standard showing parts in elevation, and r tive View of a part of the standard. lRefer-ring to the drawings morev particu- Finn-5 is an enlarged fragmentary perspecylarly numeral (-'designates a lamp standard mounted upon a base 7 andfcarryinga lamp 8.

ing 16 is tted within thecasting 13 andthe upper end of the member 12-whereby it may receive the stem 17 of a section 18which ris relatively adjustable with respect to the member 12. The bu'shinglS is longitudinally split by means of a pair of opposite slots 19 extending downwardly from the upper edgeof said bushing and dividing the ,upper portion yof the bushing into a pair of semi-cylindrical portions One of the portions 21 is in p osition to be engaged by theI inner end of the screw lwhen the same is turned inwardly for clamping said portion against thestem l?. The other portion 21 is brazed or other-v wisesecured to the interior of the castinggl and the member 12. j f The section 18 is provided on its upperI end with a pair ofspaced clamping ears 21 and j 22 respectively on opposite sides of a disc 23. The disc 28 is secured to the lower end cfa curved sectiony 24 of the standard. A screw n 25 provided with a manually operable knob 26 extends transversely through the center of theears 21 and 22 and the disc 23 for rotatably supporting said-disc between said ears and cooperates with said knob for clamping said disc between said ears. The ear 22`is detachable and may be removed byfremoving the screw 25. This. earis provided with a bi-k furcated lower end cooperating with a lug 27 for preventing rotation of the ear. This con.- struction l facilitates assembly and enables the ear Q2 to be clamped against the disc 23 with a minimum of force eXerted on the knob 2G.

The section 24 is in the form of a hollow tubular member the upper end of which is bent approximately ninety degrees from the lower end. Said upper end is embraced by a casting Q8. The casting 23 like the casting 13 is provided with an adjusting knob and screw 29. In this case the upper end of the tubular member 24 forms the bushing and said upper end is longitudinally slotted as at 3l to form two semi-cylindrical portions 32 and 33 respectively. The semi-cylindrical portion 32 is in position to be engaged by the screw 29 and the semi-cylindrical portion is brazed or otherwise secured to the surrounding casting 28. A short section 3a is proi'fided with a stem 35 at one end and said stem extends into the upper end of 'the member 24; within the casting 2S and between the portions 32 and 33. The screw 29 may thus be turned inwardly or outwardly to clamp or release the stem 35.

The outer end of the section 34 is in the form of a fiat rounded portion 3G which is clamped between a pair of ears 37 and 3S. rllhe ears 37 and 38 form a part of a bracket 39 which is rigidly secured to the lamp 8. A screw 4l extends through the ears 37 and 38 and the portion 36 therebetween whereby the section 34 is pivotally secured 'to the bracket 39 and cooperates with a wing nut 42 whereby the bracket may be clamped in any desired pivotal rela-tion with respect to said section. The ear 37 like the ear Q2 is detachable by merely removing the screw il but is provided with al lug lL3 extending in a recess 44: in the bracket 39 for preventing rotation of said ear. Thus the detachable ear Afacilitates assembly and isfree to move axially with respect to the screw il permitting clamping action to be had by a minimum of force exerted on the screw by the wing nut d2.

It will be observed that the at'oredescribed standard including its various sections and connections therebetween may be adjusted with a minimum of ease to bring the lamp into most any position desired without necessitating removing the lamp from the'standard or removing the base of the standard from its normal position on the floor.

I am aware that many changes may be made and many details varied without. departing from the principles of this invention and I therefore do not wish to be limited to the details shown or described.

I claim:

1. In a lamp fixture7 the combination of a base, a lamp and supporting means therefor connected to said base, the connection between said means and base including a disc on one of the connected parts and a pair of clamping ears supported on the other part on opposite sides of said disc and an adjusting screw for pivotally connecting and clamping said disc and ears together, one of said ears being detachable by removing said screw, said ear having a slot near one of its margins, and a lug engageable with said slot carried by said ear supporting part for preventing rotation of said ear.

2. In a lamp iixture, the combination of a base, a sectional standard on said base, one section of which is a stem telescopically adjustable with respect to a tubular member, a lamp and supporting means therefor connected to the stem, the connection between said means and stem including a disc on one of the connected parts and a pair of clamping ears on the `other mrt on opposite sides of said disc and an adjusting screw for pivotally connecting and clamping said disc and ears together, one of said oars being detachable by removing said screw and being held .against rotation relatively to the part on which -it is supported by means of a cooperating slot and lug, one of which is formed on said supporting part.

3. In a lamp iixture, the combination of a base, a lamp and supporting means therefor connected to said base, the connection between said means and base including a disc on one of fthe connected parts and a pair of clamping ears on the other part on opposite sides of said disc and an adjusting screw for pivotally connecting and clamping said disc and ears together, one of said ears being held against rotation and connected to its supporting part only by cooperation of a lug and a slot one of which is a part of the ear, said lug and slot :permitting the ear to be movable toward its opposite ear comparatively freely.

In witness of the foregoing I allix my nature.

NORRIS E. GOODIICH.
