to attain the end stated and one employing a plate and an attaching device, the latterbeing preferably according to my preferred embodiment illustrated in accompanying drawings and hereinafter described. I

In said drawings; I Fig. 1 is a fragmentary view of a can adapted to containether and; having my dropper device in place thereon and being in side elevation;

Fig. 2 is a plan view of the'parts of Fig. 1 Fig. 3 is a plan view of the dropper device;

Fig. t is an inverted view of the dropper device, and

Fig. 5 isa central longitudinal section of the dropper device as on line 5-5 of Fig. 8.

Like reference characters designate like or similar parts throughout thedifferent views.

Referring specifically to thedrawings, l.

represents the usual type of ether containers, having a flange or'projecting bead 2 around the mouth,. and the latter being closed by a stopple sheet or cover 3, of soft.

easy punctured material.

The invention utilizes a plate 4 of any suitable material. preferably metal and of any approved shape; As shown in the drawings, this plate tapers to a dropper proper 5, substantially pointed and bent or curved outwardly as seen in Figs. l and 5.

A length of resilient spring wire is employed and formed at the central portion into an arch or clasp 6, from the ends of which spacing arms 78 extend. Portion 7 of said arms extend outwardly and serve to dispose the arms of the arch at a distance within and from the sides of plate whileportionsfl8 space the arch from the plate. The arch is bowed as shown at in Fig. 5 Arms 10 receive the ether on its under surface. The ether ;when the can is'tilted flows onto and x down said under surface of the of any desired shape extend .from. arms 7-8 and may be seeured to the plate in any suitable manner, as by soldering as at :12, In use,.thecan 1 at the cover-3, is punctured as usual by any suitable instrument to provide one or more outlets 13, and a vent opening'll. Instead of the anesthetist manipulating a'finger over theopenings, in-

serting a. wick ori grooved cork, my attachmentmay be used. This is accomplished by sliding the sa-me'over the mouth of the can, wlth the head 2 being received between plate 4t and arch 6. Said head is grasped by the arch frictionally and more eflectively; in

viewof the bow at 9; .andthe attachment while-readily applied, will not be easily ac-.

cidentally displaced. The cover orplate 4 is positioned overthe opening 13 so as: to

point 5' and then drops'therefrom.

Merely the preferred embodiment has been illustrated and described hence changes within the spirit and scope of tion may be resorted to.
