yApplication filed March 30, r1923. Serial No. 628,726.

To all' 'whom it may concern:

Be it known that I, VALTR ERNEST GUN- NnRsoN,.a citizen of the UnitedStates, residing at Milton, in the county of Rock and State of 'Wisconsim have invented certain new and useful Improvements in Adapters, ofwhich the following is a specification. This invention relates to adapters.y It will be explained as applied to an adapter for use with therapeutic lamps.

Some of the appliances or applicators used with therapeutielamps in thc/treatment of disease are in the form of rods of quartz and other suitable materials. Such rod like vapplicators are primarily used to direct and apply the lamps raysl to body cavities. The adapter hereinafterv set. forth is vparticularly adaptedvto attach such applicators to therapeutic lamps.

An example of a therapeutic lampl with which the herein-described adapter may be used is disclosed in United States Patent No. 1,435,193; granted November 14, 1922. One of the objects ot'this invention is to provide an improved adapter. Y Another object is to provide an adapter which will 'readily accommodate a variety of shapes and sizes of applicators.

Another object is to provide an adapter particularly adapted to receive and hold rod shaped applicators. v

Y Another Objectis which is simple, reliable, readily manipulated.

` Other objects and after appear. j v

v"An embodiment of the invention-is illustrated in the accompanying drawing, wherein` Fig.- 1 is an .Outline perspective Qf @typical therapeutic 'lamp with fan adapterfor application thereto.

Fig. 2 is an enlar of the adapter, an

Fig. 3 is a longitudinal section thereof. Adapter 1 is adapted for attachment to a therapeutic lamp 2 and to hold an applicator 8. Both the lamp and the applicators may take various forms. Ordinarily the 50 lamp comprises a suitable casing or housing, a ray generator, such as a mercury vapor tube, within the casing and the necessary electrical connections and terminals. Often the casing is double walled to permitv 55 circulation of a cooling fluid, and then water to provide an adapter inexpensive and advantages will hereined separated perspective employed the' lamp into cavities of lthe body. It is i shoulderf15.)

or other fluid connections.v are provided. The applicators often take the form ofv rods or stemsy of various lengths,l sizes and shapes. vSuch applicatorsare .ordinarily to direct or conduct'the rays from 60 highly desirable that a variety of diiferent applicators may be readily applied to and removed from aA single lamp. i

The applicator has an attaching plate 5 which may be .of substantially rflat and circular shape. Plate 5 has a rearwardly projecting annular flangev 6 Awhich may be knurled lto provide a surface whichmay be readily ygrasped .to apply and/remove theV same from a lamp. Flange 6 may have rearwardly projecting locking lugs 7. These lugs .may fit' into corresponding slots in the lafmp casing o1" .theyimay be adapted Vto fit into slotsof'a lamp attaching unit or section such as setforth in'FritZ- A. Anderson ap# plication Serial No5-14,217 iiled November 10, 1921." i `Plate 5 has a l A forwardly projecting tubular hub v8 whose bore, when the plate isin posi'- tion, aligns witlrthe ray projecting opening 9 of the lamp casing. Thev rear portion 10 'of 'hub' 7 is enlarged and eXteriorly threaded. The /forward'reduced portion of hub 7 divided or bifurcated into two vsimilarv segments 11?' by longitudinalv slots 12. Segments 11 are beveled Vorsloped toward their outer or forward lends, and, throughout the bevel,fslots 12 are enlarged to formA jaw recesses 1,3. Anannular shoulder 14 marks Y the'k junction of the lreduced and enlarged portions of hub 8.v

" The'bore through lhub 8 is reduced in diameternearfitsi rear Aend to provide -a -A pair of similar kjaws '16 are interconnected by a small U shaped biasing and supporting spring 17. The ends of the legs of spring 17 are secured in holes in the base surfaces of jaws 16. The yoke 18 of spring 100 17 is bent at substantially a right angle to the y.plane of the legs of the spring so as to form a foot, adapted to restupon shoulders 15. The yoke is curved so as to remain clear or outside of the reduced bore of the hub and not obstruct the passage of the rays. One of the jaws V'16 slidably lies in each jaw recess 13 and is supported by spring 17 with its inner end slightly above the back of they recess so as to give suiicient clearance for the movement of the jaws. Jaws 16 are tapered or iared from front to back so that they may be forced together as will be hereinafter described.

An internally threaded tubular cap 2O is adapted to screw upon the threaded rear portion l0 of hub 8. The forward endet the bore of cap 20 is trusto-conieal shaped, approximately to correspond to the taper or slope of jaws 16.

The tendency of spring' 17 is to separate jaws 16 but, when cap 2O is screwed upon hub 8, the interaction of the sloping or tapered surfaces of the jaws and the boreV of the cap provides a wedging action which 'forces the jaws together against the bias of spring 17. The jaws are caused to approach as the cap is turned back so that the clamping action of the jaws upon an applicator lying therebetween may be varied as desired. lhencap 2O is screwed outwardly the wedging action decreases and the bias of spring 17 separates the jaws.

Applicators may be readily applied to the lamp by inserting them between the j aws or' the adapter, where they are in the path of the rays, and then turning the cap to cause the jaws to clamp. An applicator' is readily released by turning' the cap of the adapter in the reverse direction.y The clamping races of the jaws may be formed to `meet any special and peculiar condition as to shape ot applicator. It necessary, each'adapt'er may have several sets of jaws and springs assembled into units which may be interchangeably applied by merely removing the cap.

Having described my invention what 'I claimas new and desire to secure by Letters Patent, is v i l. An adapter for attaching applicators toa therapeutic lamp and comprising, a hollow hub for attachment to the lamp and through which the lightmay pass, appli'- cator clamping jaws Yadapted to be moved toward: and from each other to clamp and release an applicator therebetween, resilient means yfor supporting the'jaws on the hub andaifording 'an unobstructed `light pa's- Y sage' to an applicator held by thejaws and acting to bias the-jaws apart, and a` cap cooperating with the hub and jaws to hold the same together and so` that movement of the cap in one direction causes the jaws to approach each other and movement in the other direction permits the jaws to separate. 2. An adapter for attaching applicators toa therapeutic lamp and comprising, a hollow threaded hub, a pair of relatively movable clamping jaws, a spring for holding and biasing the jaws apart, said spring being formed so as not to obstruct the passage of light through the bore of the hub, and a hollow cap adapted to be threaded upon the hub and acting'upon the jaws to force the same together against the tension of the spring.

3. An adapter i'or attaching applicators to a therapeutic lamp and comprising, a plate for attachment to a lamp and having an opening therethrough; a tubular eXteriorly threaded hub on the plate, the bore of thehub aligning with the opening inthe plate and having a shoulder therein; a springresting on the shoulder in the bore of the hub; a pair of jaws supported and biased apart by the spring; and a cap threading upon the hub and acting upon the jaws to force the same together against the bias of the spring.

"4. An adapter for attaching applicators to a therapeutic lamp and comprising, a plate for attachment to a lamp and having an opening therein for the passage of light; a slotted tubular Vexteriorly threaded hub projecting from the" plate, the bore or the hub aligning Vwith the opening in the plate and having a shoulder therein; a substantially U shaped'spring whoseY legs lie parallel to the bore of the hub and whose-base is curved' so asfnot to obstruct the passage of light and formed at an-angle to the legs to` provide a Ytoot tor resting on the shoulder about thebore ot the hub; a pair offcooperating jaws, one carriedby'each leg of the spring and lying in one of the slots of the hub; and a threaded cap for application tothe huband cooperating with the rjaws to move the salme'.
