My invention relates to means-"for administering radium emanation and involves a construction whereby practicallythe entire emanation resulting during each opening and air admitting period of operationwill be administered to or obtained by they user with each withdrawal ory inhalation and as a result more uniform quantities of the radium emanation is obtained in keeping with the prescribed doses. y

The invention also" has for itsobject the provision of a construction whereby the radium element is preventedy from contact with outside Y'air andescape of theradium preventedwhile the device is not inuse.

The invention also contemplates a construction which will permit an increased quantity, or dose of greater strength, to be administered with each inhalation or withdrawal. f

The `objects, and advantages of my invention will be readily comprehended from the detailed description of the' accompanying drawing, wherein- Figure 1 is a sectional view of my improved emanator shown in condition for use; the withdrawal tube and water-holdingl-vessel or glass beingonly partially shown.

Figure 2 isa detail sectional view taken on the line 2*-2 of'Figure 1 looking inthe directionof the arrows.

Figure .3 is a sectional viewy ofthe device,-with a portion in elevation and the Withdrawal tube broken away,'--andy provided with an auxiliary yemanation administering portion.

VMyinvention relates to a device intended for administering the, emanation of radium',

in conjunction with agiven quantity of pure vwater or other media; the device -being such that` the air, before entering and passing about thefradium element, when the device 'is iny operation, is made to passthrough a suitable air purifying medium inadvance ofits contact with the radium element and therefore inf advance of the emanation coming into contact withythe waterfor other fluid media with which thesame are administered.

In the'specific yexempliic'ation of the invention as disclosed in Figure 1, the device 'the valve.

communicates witha duct 2&2, at they inner Lend of the plug-valve,y which connects with a port f shown in Figure l. a

" Thechamber 21, at ari-intermediate point,

Vcomprises a casing or housing 100i any suitable configuration andy ycored to receive a plug-valve 11. In thedevice as illustrated,

the plug-valve 11 is` preferably of the tapered type having the threaded stud' y12 disposed through one side wall of the-casing 10 in order to receive the nut ll?) whereby the valve is held in'place and at thefsame time its proper ittingrelation with the casing 10 maintained'.

'The opposite 'end'of the plug-valve lllias an externally threaded extension 14, which receives a suitable hand-Wheel or controlling member 15 wherebythe plug-valve may be tration withtheV respective ports in the casing 1-0. The hand-wheell may be secured tothe extension 14 in anyfsuitablemanner, for erample .by means ofthe set-screw 16.] Thev internally threaded hub portion of the handlother Vendofthe springis secured to the handwheel at 19. It is obvious with this construction thatfth'e hand-wheel 15 willv automati-.

callyV return to its normal position (which 'constitutes ythe'closed positionof the valve) when the operator releases the hand-wheel. I-n order to'prevent'improper contact withithe may bey omitted if desired. f

The plug-valve KV11 'is cored longitudinally from yone end thereof to a predetermined extent in order to vprovide af chamber 21 within The inner end of the chamber 21 ycoil spring,l I" prefer to employ the enclosing cylindrical shell or collar 20 which, however,

23 and-which in turn, when the valve is in f f open position, communicates withfa port 24 valve is intended to hold the radiumeleinent, generally indicated at 25,l .which is preferably jplaced'in a wire meshcapsule is internally threaded Vto receive a` closure plug o'r containeras f es Y held within the inner end of the chamber 21, intermediate of the duct 22 and the plug or screw 26 and therefore normally out of contact with air.

The plug-valve 11 is provided with a port 27 which enters the chamber 21 forward of the closure plug 26. The port 27 in turn is intended to register with ay port 28y in the casing l() when the plug-valve has been properly turned to open position.

The casing 10, about the port r28, is counterbored to provide a pocket 29, which, in Figure l, is shown provided with a suitable air filtering element, such as asbestos, Wool, cot; ton, or the like, indicated at 30, which is preferably laced intermediate of the wire-mesh or per orated discs 31; the discs and air purifying element being held in place by a suitable yWasher 32 screwed into the threaded counterbore; the washer being provided with a central opening to permit passage of air therethrough.

f The port 24 in casing 10 is provided with a tube 33; and the casing is provided with a counter-bore encircling the 'port 24 and tube 33 for the purpose of receiving the large tube 34y shown threaded into the counterbore in order to permit assembl and removal. The large tube 34 is prefera ly longer than tube 33 and has its lower end provided with a suitable cheek-valve 35 for normally closing the inlet port 36 in the closure member andfvalve housing 37 and thus prevent discharge or `radon through the lower end of the tube.

The casing 10 at one side of the plug-valve 11 is shown provided with a duct 38 extending therethrough; the lower end of the duct communicating withtube 34 while the upper end of the duct is provided with withdrawal tube .39 (see Figure 2) a portion of this tube being preferably iexible or of rubber to permit the same to be taken into f the mouth ofy the user `for the purpose of withdrawing,-by means of suction,-the liquid or Water and result-ant radium emanation.

When the device'is not in use, the springvl7 will rotate the plug-valve 11 in such direction that ports or ducts 23 and 27 kwill be out of register with ports 24 and 28, respectively, and as a. result air cannot enter chamber 21 and come into contact withthe radium element indicated at 25, hence no emanation can be emitted because no withdrawal can be made from the inner end of the chamber. 21.

When the device is intended to be used, the lower end of tube 34 is inserted into a glass or suitable vessel 40, containing water or'other proper media; the free end of tube 39 is placed in the users mouth and plug-valve 11 is rotated by turning hand-wheel15 so as tobring port 23 into register withfport 24 and port 27 into register with port 28. Suction on the tube 39 will cause air to flow upward through the purifying or air filtering into chamber 21, allowing it to pass about the radium element 25, out through duct 22, ports 23, 24 and tubes 33 into the immersed, fluid holding end of tube 34. The suction will cause check-valve 35 to move upward off its seat, causing the liquid from the vessel 0r glass 40 to pass upward into tube 34 into contact with the radium ema-nation and to be charged thereby; the emanation holding Huid then passing upward through duct 38 and out through tube 39. As soon as the user has taken the requisite quantity and releases hand-wheel 15, spring 17 will rotate plug-Valve 11 in the reverse direction back to normal condition where ports 23 and 27 will be'out of register with ports 24 and 28, re-

spectively; while check-valve 35,k which is held in the closure member 37 by perforated cap 41, will drop to its seat. The check valve 35'is employed to prevent loss or passage of the emanation into atmosphere and the takeoff tube 39 is also preferably provided with a check valve as at 39a to prevent improper use.

In Figure 3 I show my improvedy emanator lprovided with an auxiliary radium element holding receptacle intended to be employed when the user is to receive a double strength dose as it were, namely where a greater quantity of emanation is to be taken with each withdrawal thanmight be obtained from the quantity of radium held within the chambered valve of the main casing as described in connection with vthe construction shown in Figure 1. The construction disclosed in Figure 3 shows the casing 10 vhaving the plugvalve 11, which is identical with that disclosed in Figure'l and controlledibythe hand-wheel or grasp 15. The casing 10, as previously described, is provided with the ducts or ports 24, 28 and 38 (the latter not shown); the latter duct establishing communication with the large outer tube 34 which is intended to be inserted into a liquid-holding vessel or glass; said tube 34 encloses the small tube or stem 33 which communicates with outlet port 24 in the casing and which is intended to have communication with port 23 in the plug-valve 11 when the latter is properly rotated. Such rotation of the plugvalve will cause the port 27 in the valve to be brought into register with the port'28 in the casing. The valve 11 in Figure 3 is shown in closed osition. The inner tube 33, as shown in igure 1, is purposely shorter in length than outer tube 34, so that when outer tube 34 is inserted in the liquid or water in vessel 40, the emantion discharging through tube 33 will pass into the fluid or water which has entered tube 34, and be entrained with the fluid, asthe emanation will rise toward the upper end of outer tube 34 when the device is in use. As a result, the user will receive all of the emanation when the valve 11 has been turned to` open position. n

k'Vl/'here an additional i or auxiliary supp-ly of'vradium is to be administered, the enlarged counterbore 29 aboutkport 28 receives. the threaded nipple 42 of a casing 43. Before the nipple 42 is lscrewed into thelcounterbore 29, the filtering element with the'disc 31 yand Washer 32 are removed. The casing 43,:which maybe of any suitable configuratiomis shown provided with yanrannularflange 44 on the lower side and externallythreadedto receive the cylinder 45 shown'internally'threaded at theupper end. `The casing is formed to receivea plug-valve46, controlled by the handle or lever 47 the valve being preferably tapered yand secured in place by the rnut 48 aitthe' opposite or small endfthereof. The plug-valve is provided at predetermined points with ports 49 and 50 extending therethrough.y The port 49wis intended Vto bey brought into register `withan lair inlet duct 51.; while port 50 is intended to be brought into register with outgoing duct 52. W'here `oiireceptacle '45 is shown'provided with a `lug or teat adapted to engage in a socket 'in the'flower'end Aof'handle 47 to rictionally hold the latterwith the valve in inoperative or closed position,y

`When the deviV eis used, handle 47 is" oscillated to rotatetheivalve-46 into a'position T(if).

where its .ports 49, Oxarebrought into register withducts :51 andr52grhand-wheel 15 is then rotatedfsoas to bring ports 23 and 27 vof, plug-valve 11 iinto register with ducts 24 andf28, respectively. i .Asduct 28 of casing l() is in register withthe-ductk 52of casing 43,'it- -is'apparent'that communicationk will be es-V tablished with auxiliary vessel 45. The user thenzplacesthe Aouter tube 34, which maybe termed the mixing chamber, into a vessel7con- Atainingthe desired fluid and .upon inducing Asuction in'lthe device,` causes vthe Vai-rf to pass through the iilterfhfdown through tube 53 and upthroughV tube 54 and into the chamber of valve 1l.v This causes the emanation yresulting from-'the' ra-dium'inrthe auxiliaryY receptacle 45 and Jromthe' radium 25 in valve llto pass downthroughinner tube 83 and dischargeinto large outer tube 34 and with the'fluidrfrom the vessel 40 topass up through duct 38 out throughf tube 39.

' have shownwhat'l 'believe-to be the best embodiment ofthe invention, and have de-v Yscribed the 'same inte'r'ms' employed merely as terms of. descriptionand not as terms of limi,H tation as modifications may be made without departing from the spirit kof my invention.
