, Application filed February invention relates to diagnostic reflec i tors worn on thehead byoptioians', physiclans and the li for use in the illumination ofthe eye's throat, etc a In the presentuse of such reflectors, par- 1 ticularly in diagnosing throat affections, it

is highly desirable'that the wearer of the reflector be protected against the cough ng of a patient. It is therefore, a purpose. of my invention to provide an attachmentfor such reflectors which. operates to effectively shield the nose and mouth ofthe wearer. I

It is alsoa purpose .of niy in'vention to provide a rnouth andnoseshieldcapable of being associated with afhead reflector n a. Inannerfto allow of an adjustmentthereof "with respect to the nose and mouth ofthe wearer} to permit of its movement to and retention in a non-shielding position when the shield is not'in use; and the mounting f thereof on. the headband of therefiector so v as to present alsmo oth andhuninterrupted surface to the inner sideof the band onto the head ofthewearer I'Wmdescribe 0111. .Q QifOrm of nQ at d mouthshield embodying my invention and Q its adaptation to a conventional form fo't "diagnosticreflector and will then polnt out the novel features thereof in claims. f

As shown inF-igure 3,.the sleevesq28are' i spaced apart to receive therebetween tongues 30' on the vertical edgesoifi a, resilient. plate 31, this-plate functioning as a spacer and locked. against vertical movement :through. themedium of the tongues 3O engaging; the

. as shown in Figure 2, it is supported in spaced relation to the plate 29. A-locking Washer 32 is adapted to be interposed between the ball head 18 and the plate 31,'as clearly-shown in Figure 2, and this washer is provided with a s'lot'in which the'shank17 is received. The washer is designed to occupy the space between the head 18 and the plate 31 and when applied funetions'to aflex the platev inwardly, thus placing the plate under tension andithereby exerting suflicient pressure upon 'thetongues to cause the latter to bindingly retain the extensions 27 [against accidental movement, so that any vertical T,adjustment of the extensions :can be maintained. The "tension *of the plate J31 created as just described also functions to spread'thewasher 32 andtheplate 29which' sets up .suflicient friction between "the wash j Y is not-inuseflt'may'beswung-tothe elevated position shown in dot and-dash lines'inFigj er and the head '18-and'the plate 29 and the band 15 to vreleasably retain -the entire mountin'gjin any circumferentiallyadjusted position, to alloiw -rota-tive movement of the plates on the shank but to iricti'on'allyretain the plates in any :circumferentially adjusted dental displacement from thefsh'ankthrough indentationsfil in the plate 31, all as clearly. shown in Figu ref5.

The' sliieldinaybe adjusted to properly protect "the nose and? mouth' by vertical -movement of the extensionsQZ in the sleeves"28. "-When 'thesliield u re 1', and by virtue of thew-operation of the parts of the shield mounting, asjpre viouslyv I described, it will "be manifest 'that' the shield is frictionally maintained in such elevated position against the possible dropping-flofthe shield to vertical position.

' Although have herein shown and de scribed only one formof nose and mouth shield-- embodying my invention, it is to i be understood ivar'ious changes and modifications :may be made t-herein :without -'de parting from the spirit of the invention and the spirit and scope of the-appended claims.v
