Patented Oct. 29, 1929 DONALD E. ROBERTS, OF MILWAUKEE, WISCONSIN APPLICATOB FOR CONDUCTING ULTRA-VIOLET RAYS Application filed January 31, 1929. Serial No. 333,445.

The invention relates to applicators for conducting ultra-violet rays, which use quartz as a conducting material, and are comprised of a multiplicity of quartz segments;

such segments being housed within a rubber tube. The objects of the invention are, first, to provide an efiicient and safe method to join the segments, and, second, to reduce as little as possible the useful diameter 01": the

assembled applicator.

One form of the invention is illustrated in the accompanying drawing, in which Figure 1 is a View of the assembled applicator; Fig. 2, is a cross section of the assembled applicator with some quartz segments removed for the purpose of simplicity of illustration;

Fig. 3, is a cross section o1 the applicator through XX, Fig. 1; and Fig. 4, is a view of a quartz center segment as at 2, 2, 2, 2, Fig. 1, and 2, Fig. 2.

The applicator for conducting ultra-violet rays as covered by this invention consists of aquartz base segment 1, Fig. l, and 1, Fig. 2, and a multiplicity of quartz center segments,

2, 2, 2, 2, Fig. 1, and 2, Fig. 2, and a formedquartz tip segment 4, Fig. 1, and 4, Fig. 2, and a friction clamp made of spring metal as shown at 5, Fig. 1, and 5, Fig. 2, and 5, Fig. 3, and a Browne and Sharpe gauge silver wire shown at 6, Fig. 1, and 6, Fig. 2, and 6, Fig. 3.

Figure 2, shows how each quartz segment is drilled through the center; the formedtip segment 4, Fig. 1, and 4, Fig. 2, having a transverse and two diagonal holes as shown at 4, Fig. 2; thebase segment 1, Fig. 1, and 1, Fig. 2, being drilled so that the hole has its outlet so that thewire 6, Fig. 1, and 6, Fig. 2. and 6, Fig. 3. may be placed underfriction clamp 5, Fig. 1, and 5, Fig. 2, and 5, Fig. 3.

Figure 3, shows method ofholdingwires 6, Fig. 1, and 6, Fig. 2, and 6, Fig. 3, underfriction clamp 5, Fig. 1, and 5, Fig. 2, and 5, Fig. 3.

Figure 4, shows a quartz center segment as at 2, 2, 2, 2, Fig. 1, and 2, Fig. 2, with one end dome shaped and the other end cupped shaped and each end polished so as to pass ultra-violet rays more etficiently.

One end of the base seg ment 1, Fig. 1, and

1, Fig. 2, is flat and po ished, and the oppoend is dome shaped and polished. he base end of the quartz tip segment atsite 4 Fig. l, and 4, Fig. 2, is cup polished.

The lengt changed by quartz center segments as at 2, 1, and 2, Fig. 2.

Due to the segments being strung on the flexible silver wire, and the slight ball and shaped and h of the applicator may be the addition or subtraction of 2, 2, 2, Fig.

socket oint action of the segments made possible by the ends of the segments and cupped, the applicator is slightly flexible.

Due to the property of quartz as a con ductor of ultra-violet rays even when placed being domed when assembled at an angle adjacent to another piece of quartz, ultra-violet ra this ciency even when the ys are conducted by applicator with but a slight loss of eflibent.

he method of assembling the applicator e silver wire is first placed through the transverse hole insegment 4,

I am aware that prior to my invention, applicators for conducting ultra-violet rays have been made of a multiplicity of quartz segments and with formed tips,

ators when assembled, bei

but such apng held together With but a rubber tube, have no precaution to prevent the segments being lost While Within a sinus While the applicator is in use, and in such applicators, the rubber tube used to hold the segments together takes up extremely valuable space. I make no claim to y me 0d o man a tur n such applicators nor, in a broad Way, applicators coinprised of a multiplicity of quartz segments. I claim: An applicator for conducting ultra-violet rays comprised of a multiplicity of polished quartz segments, having the segments fastened together by means of a ire which passes transversely through the tip segment, an ag a y th u he tip se ment to the ba e 10 h p'.$ m n a a p r the center of each center segment enamel; through the center of the base segment ancl 911? he ide 9,1 t b se s h ug a diagonal hole and fastened in place under a fri t qn amp in the man r cr b $1 wa lca fiz be n s ght y i e ibl an wr s ale s' a t DONALD E.
