Marden et al. and assigned to the Westinghouse Lamp Co., which lamp i`s provided with a thin recessedrwindow` portion i9 in the end thereof more' pervious to ultra-violet radiations than the remainder of the envelope. Surrounding the tour of the envelopeof the lamp. This is held in firm contact with the end` of the envelopey through the medium of a" pluralityof resilient fingers or the like 22 `secured to the collar 20,

such as by screws 23, and -extending overthe envelope in the direction of its longitudinal axis with the ends of the fingers 22 being held against' the envelope by, aretainngring 24 which may be in the form-ofa` coiled'spring, thus forming a guard for the lamp. The fingers 22 extend slightly beyond thecollar 20. and are provided withr angular portions'25. bent inwardly for the purpose ofengaging a disc 28 of suitable heat resisting materialiforY the purpose of preventing thejlamp from actually contacting the patient and causing discomfort of any'na'ture. .y f

1 `Thisdisc 281s provideduwith 'an openingl21 of approximately the same diameter as that of ythe thin `Window portion I9 ofthe lamp for the egress of radiations as well asf a plurality of transverse lslots 28 (Figs. 5 and 6) and a peripheral groove 28. VInorder toposition the disc 26 upon the col- Vlar 28 to complete' the lamp guardthe angular "portions of the resilient fingers 22 are passed "partially through the transverse slots 28, until the same align with thperipheral groove 29 after which the disc is given a slight rotary movement Y `thus retaining the same in position.

Y A similar discjl is provided as anaccessory which in most respects is identical to the disc 28 with the exception that it is provided with only a very small v,opening 32 serving as a vent to permit escapement of air from the recessedthin window portion I9 of the envelope in4 lieu of the larger opening 21jas in the disc 28. This latter disc '38 is adapted to be placed upon the lamp i "guard in place of they disc. 28 when the lamp is g not in use and completely protects the end of the lampv I8 and particularly the thin window portion I9 to prevent accidental breakage.

The lamp unit as' Justvdescribed together with the transformer 9 is arranged to be disposed within aportable container asshown more clearly in Figs. 3 and v4. This'container is provided with a closure member or `lid 34 hinged thereto rtogether with a suitable handle 35 .and fasteners 88. The interior of the .container is provided with a plurality of

compartments

31, 38, 39, 40, 42,

' and u and the ultra-violet lamp la together with `a spare lamp 44 arenormally disposed within vthe compartments 31`and 38 and closed by a separate cover plate 48 v(Fig. y4). Various other accessories, such as a lamp cord 4B is disposed withln the compartment 39 which is employed for connecting the primary winding of the transformer 9 to a suitable source :of electrical energy fof the usual commercial potential, and in the f compartment 4.0'are disposeda pair of ultra-violet impervious spectacles 41 as well asthe disc 26 'when replaced by the disc 20.

. novel:

The transformer 9 which is provided with a suitable handle 48 for detaching the same from the container 33 is retained within the compartment by rmeans of vspring clips or the like 49 engaging hubs 50 provided on the transformer housing.

The lamp unit on the other hand is secured to the underside of the closure member 34 by spring clips 52 which engage the reflecting shield I4 and all parts of this unit and particularly the pistol grip yhandle 5 vwhich extend beyond the surface of the vclosure member or cover 34 are arranged to fit into the compartment 43 upon closure of the end of the lamp l8'is an annular collar 20 having a slightly tapered surface conforming to the con- .former thereto by the cord 46. f l

It can thus be readily seen by those skilled in ythe art that I have provided an ultra-violet apparatus of a compact portable nature which may be transported from one place to another with ease. Moreover, the various members utilized during the actual administration of a treatment are readily yremovable from the portable container enabling them to be employed lwith still greater facility at any desired location. The lamp unit itself may be readily gripped by the user so as to apply the treatment to any desired area of a patients skin while actual contact between the lamp and patient is prevented by a suitable guard and the user can observe the proper positioning of .the lamp while being shielded from stray radiation by a reflecting shield.

Although I have shown and' described one embodiment of ,my present invention I do not desire to be limited thereto as various other modifications of the same may be made without departing from the spirit and scope of the appended claims. Having thus described my invention I claim as 1. A portable ultra-violet radiationv unit comprising a handle having a configuration readily adapting the same to hand gripping by a user, a socketcarried byisaid handle, an ultra-violet lamp adapted to be energized and to generate ultra-violet radiations within a preselected region of the spectrum disposed in said socket, a refleeting shield supported by said handle for directing'the radiations emanating from said lamp in a desired direction and for preventing radiations from falling upon the hand of a user when holding said unit. and at least-one window in said reflecting shield pervious to visible radiations but impervious to ultra-violet radiations to enable one to observe the positioning of said lamps Without being subject to radiations from the latter.
