Figure :5 is an inyertedfplan'thereof.

rh'therapeutic appliance in accordance with this invention includes an adjustable lampsufppoi ting standard, a flexible hanger,

carried by the hanger, a directing element for the light rays, and 'a base for 'the standard. v p

The adjustable supporting standard is of thetelescopic type comprises a lower I tubular s'ection l and an upper tubular 'section 2, which extends in the upper end of the section 1 and further is verti'cally adjustable relative to the said section 1. The supporting standard is constructed of any suitable in'etallic material, f i t The sectionl is prov ded at itsjup pf eiid .withPQrip h e d 3 M d it t bite end with Y a reduced peripherally threaded 'terininal"port ion 4, and ajbove the latter carries an adjustable threaded collar 5. I ,,,Th ndar lcOi iec d to ws lp- Ported by a eba'se'consistiiig of ahollow'hody portion said a cover 7 therefor, and each of which is fbrr'ned from metallic material, and 'Witht'he body portitinfi of materially greater weight than theeoverZ, and further with the. latter conforming in contour to and snugly fittingthe outer face of the body portion 6,

The base isopeini at jits bottom and has a closed top flattened centrally thereotas at 28. I. The base preferably s, circular in contour, but it is to be understood that it, can be of any shape desired." v c The body portion, 6, centrally ofits top is formed withanopening 9 havingits wall threaded, and said cover 7,, centrally; thereof is providedv with an opening 10, isters with the open'ingQ,

, The reduced lower terminal portion is i which reg- .exte'nded through: the openin g 1'0 and has threaded engagement with the wallof the opening 9 whereby said section 1 is secured in an upright position bythebase. The collar5 is adjusted downwardly in the section 1 to engage the flattened portion 8, of the base,

so that the cover 7 will be tightly clamped tothe body portion 6;

f The section 2 of the standard, at upper end is provided with peripheral threads 11, and said section 2 has its lower terminal portion 12 provided with a pair of diametrically opposed insets 13, forming a pair of lengthwise extending grooves 14; opening at their lower ends at the inner end edge of said section 2 At tht upper end of each oi the-greoves '14, the section 2 is formed with an opening 15, for the purpose of pivot-ally conn'ecting to the section 2 21 depending resilient trictional clamp formed from a single length of spring wire.

The frictional clamp comprises a pair of side portions each having an outwardly inclined upper part 16 ot substantial length, and an inwardly inclined lower part 1?, preferably of greater length than the upper part. The upper part in oi one side portion extends in an opposite direction with respect to the upper-part 16 the other side portion. The lower parts 1? of said side portions not only extend in 'ardly at an inclination towards each other, but i ur ther extend outwadly at an angle with re spect to the direction in which the upper parts 16 extend.

The frictional clamp further includes a top formed of a pair or

extensions

18, 19 and each thereof extends inwardly at an angle with respect to the upper end of the f upper part 16 ot' a side portion. The

e tensions

18, 19 are disposed at an inclination so that they will oppose eaclrother. The

extensions

18 and 19 are inounted in the section 2 of the standard, extend in opposite directions with respect to each other and each projects inwardly through an opening 15. By this arrangement the frictional clamp is pivotally connected to and suspended troni the section The frictional clan'ip further includes a bottom formed of a pair of semicircular portions 20. 21 and each of which is disposed at right angles to the lower end o1 a lower part 1.7. The portions 20, 21 are so disposed whereby one will be oli set with respect to the other when the clamp is set up as shown in Figure 3.

The frictional clamp further includes a coupling portion formed of a coiled upper part 22 and a pair of oppositely extending depending vertical extensions 23, 24:, oppose the lower parts 17 oi? the side portions. The extension 23 terminates in the curved portion 20 ot the bottom and the extension 24- terininatcs in the curved portion 21 oi the bottom. The coupling member normally maintains the side portions and bottom extended and acts to set up a frictional clamping action between the bottom of the clamp and inner tace oi the section 1, of the standard at two points.

The upper parts to of the end portions are of greater length than the length of the which grooves .l-"l, and the side "alls of these latter limit the shitting movement of the side portions. The grooves i i also provide clearances for the side portions 01' the clamp so that the section of the standard can be rted into the section thereof.

Tle outer diameter the section 2, with espect to the inner diameter of the section 1, is such as to provide a snug sliding iit ietween said sections, and after he section has been Vertically adjusted, the i s ictional clamp engaging w th the section 1, will hold the section 2 in the position to which it has been adjusted;

Detachahly engaging of the section 1, an n l {3 5 meta an inerniediate flexible portion 3;). of substanial length and which is fixedly connected if) t 10 sleeve 26 and 2?.

l crposed bet-ween the flexible hanger the section 2 ot the standard, is a i and couplin member tor connecting the hanger to said section 2, ans which further provides "for the entrance of the circuit connections 31 which extend through the hanger to the lamp 32. The coupling member consists of a hollow semi-spherical body 33, having an opening for the entrance thereto 01 the circuit connections 31;

integral with and depending troin the body portion 33 is an interiorly threaded collar 35, for engagement with the threads 11. Formed integral with the top of and depending within the body portion 33, is an interiorly threaded collar 36 which is engaged by the reduced threaded lower end 29 ot the sleeve 28. When the coupling member is secured to the hanger and section 2, the sleeve 28 abuts against the outer face of the top of the body portion 33, which'is flattened at such point, as at 37.

The reduced upper end 27, of the sleeve 26, detachably engages with the socket of .the lamp 32, whereby the latter will he suspended from the upper end ot the hanger and can be adjusted to any desired angular position with respect to the standard:

iilounted on the socket of the lamp 32 and inclosing and depending "from the globe oi the lamp is a directing element for the light rays, and which is in the form ot a hood cointructed from a single sheet of thin metallic material highly polished on its innor and its outer face.- The hood is circular in contour and includes a flaring lower portion 38 of compound curvature in vertical section and which is outwardly beaded at its bottom, as at 39. The hood further includes a trusto-conical intermediate portion e into which merges the top of the lower portion 38. The upper circular portion of the hood is indicated at 41, and into which merges the top of the intermediate portion. The upper portion 41 is formed at its top with an inwardly extending apertured annular flange t2 providing means for connecting and suspending the hood from the socket ofthe lamp. The intermediate portion is of lamp, with the directing element, to be positioned at any desired height, and the flexible intermediate portion of the hanger allows for the lamp and directing element to be set at any suitable inclination so that the light rays from the lamp can be directed at any desired point upon the patient without any inconvenience.

It is thought that the many advantages of a therapeutic appliance, in accordance with this invention can be readily understood, and althoughthe preferred embodiment ofthe invention is as illustrated and described, yet it is to be understood that changes in the details otconstruction can be had which will fall within the Scope of the invention as claimed.

VVha-t I claim is:

An adjustable support comprising abase, a sectional standard connected therewith and formed of an adjustable tubular upper section and a stationary tubular lower section, said upper section telescoping in said lower section and having its lower terminal portion provided with lengthwise extending diametrically opposed peripheral grooves and a contractile frictional clamp providec with right angularly disposed upper ends extending in and pivotally connected to said upper section, said clamp depending from and seating in the grooves of said upper section and further frictionally engaging with the lower section to maintain said upper section in adjusted position.

In testimony whereof, I afiix my signature hereto.
