CLOSURE FOR ETHER-RECEPTACLES AND THE LIKE.

Specification of Letters Patent.

To coZZ whom it may concern.-

Be it known that I, ROBERT H. FERGUSON, a citizen of the United States, residing at East Orange, in,the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Closures for Ether- Receptaoles and the Like, of which the following is a full, clear, and exact description.

My invention relates to a receptacle for ethyl chlorid and volatile fluids, and has particularly in view the provision of a receptacle which is normally tightly and securely closed, but which can be readily manipulated to deliver the ethyl chlorid in a fine jet or stream when desired.

A further object of the invention is to insure against stoppage of the capillary duct through which the fluid is expelled.

A still further object is to provide means by which the receptacle is automatically closed when the operator removes his thumb from the controlling means, but which may be arranged to remain continuously open when this is desirable. V

lVith these and other objects in view my invention consists in the construction, combination, in the location, and in the arrangement of parts, as hereinafter set forth and shown, and finally particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View showing a closure device embodying the principles of my invention applied to an ether-receptacle. Fig. 2 is a similar view showing the device in its open relation. Figs. 3 and 4 are detail views showing slight modifications.

Medical practitioners are commonly equipped with a receptacle for ether or ethyl chlorid or some similar volatile agent for the purpose, among others, of producing intense cold and freezing tissues upon which it is desired to operate. results, an arrangement is made by which the fluid is delivered in a fine jet or stream the flow of which can be accurately controlled. For this purpose advantage is ordinarily taken of the vapor-pressure of the volatile fluid itself within its containing vessel, which is sufficient to expel the fluid in a fine jet or stream through a capillary duct formed through the neck or wall of the vessel.

In order to secure the best Means must be provided for normally closing this capillary duct, and the means employed must not only be of a nature to secure a tight closure, but it must be easily operable and must be of such a nature as to insure against clogging or stoppage of the duct. The lastnamed difficulty is a matter of considerable practical importance, since any form of closure which exerts a tangential or rubbing action against the duct is very liable to dislodge and direct particles into the minute aperture, which are very difficult to remove. In carrying out my invention I aim to completely overcome this defect and to provide a closure secure and tight in normal relation, which is easy to operate, and which satisfies all practical requirements.

Referring to the drawings and to the various views and reference-signs appearing thereon, in which like parts are designated by the same reference-sign Wherever they occur, 1 indicates a portion of a receptacle having a neck 2, through which is formed a minute capillary duct or passage 3. The end surface 4 of the receptacle-neck is ground into a plain flat face with which cooperates the closure embodying the principles of my invention. The features thus far described of the bottle and neck are of the ordinary form and constitute no part of my invention.

I provide upon the neck 2 a casing clamp or holder 5, which is firmly fixed to the neck and which carries what I shall term a closure-guide soldered or fixed in parallel relation on its exterior surface. The closureguide 6 in my practical construction is made in the form of a metallic tube and serves to guide a rod 7 longitudinally and rotatably movable therein. The rod 7 is bent at its upper end, as shown at 8, and carries at the extremity of the bent facing cup 9, which contains a pad 10, of leather or suitable packing material. I have devised means by which the pad 9 is directed against the mouth of the duct or passage 3, so as to normally close the same.

11 designates a slot through the closureguide 6, which may be of the form shown in Figs. 1 and 2that is to say, having a lower portion 12, lying parallelwith the longitudinal axis of the closure-guide, and an upper end 13, deflected into a spiral or inclined relation.

portion a downwardly-- -enlarged part or head 16, against which bears 14 designates a side passage which extends practically in a transverse plane of the closure-guide. The slot 11 serves to receive a stud 15, secured to and forming a part of the rod 7, so that the movements of the rod are absolutely controlled by said stud and slot.

It will be seen that the rod 7 is constrained to have an initial longitudinal movement without any rotation while the stud is in the straight part 12 of the slot. Thereafter the rod 7 receives an additional rotary motion by virtue of the inclined part 13 of the slot. The relation under these circumstances is shown in Fig. 2. The stud 15 is also capable of moving laterally into the transverse passage 14 for a purpose which will be herein after stated.

At the lower end of the rod '7 is provided an the compression-spring 17, contained between said head and the bottom end of the closure-guide 6. By this means the rod 7, and therewith the pad 10, are borne constantly downward and under normal conditions' serve to maintain the duct or passage 3 firmly closed. The operation is as follows: The receptacle 1 being filled with any volatile fluid through a special aperture (not shown) or by creating a vacuum Within the vessel and then immersing it beneath a fluid surface, the stud 15 is then allowed to move into'the relation shown in Fig. 1, where it is at the bottom of the straight part 12 of the slot 11 under the influence of the spring 17. The relation is such that the pad 10 moves against the face 4 before the stud 15 arrives at the extreme lower end of the slot, so that the spring 17 exerts its full force to maintain the capillary duct 3 closed. It will be observed that in this relation the duct is not only 1 closed tightly, but it is insured to some eX- l tent against being accidentally opened, since it is impossible for any article striking the stud 15 in a lateral direction to move the same on account of the walls of the straight part 12 of the slot 11. When it is desired to I use the apparatus, it is merely necessary to press the stud 15 upward with the fingers, whereupon the pad 10 will be firstv rectilinearly removed and subsequently laterally deflected from over the duct or passage 3, and a stream of the volatile fluid will there'- upon issue in the usual way. On account of the rectilinear movement of the pad away from the mouth of the duct or passage the latter is not liable to be clogged by particles of the packing material, which would become dislodged by a transverse movement if l this were to initially take place. When the stu'd 15 is run upward into the inclined part 1 13 of the slot 11,it is not retained therein, but 1 it is free to return when the holding force is 1 removed. If it is desired to keep the recep- 1 tacle open for a length of time, the stud may 1 be moved into the transverse passage 14, where it would be held by the lower wall against the tension of the returning spring 17 In Figs. 3 and 4 I have indicated slightlymodified forms of the slot 11. In Fig. 3 the slot has two transverse branches 14, similar to the single branch 14 of the previous form, and in Fig. 4 the slot has two parallel in clined portions 13 tacle is properly opened in whatever direction pressure is applied to this construction it is insured that the bottle is promptly closed as soon as its use is discontinued.
