INHALER.

" To all wh m itwmg concern:

i Be it known that I, GEORGE ER WIOLD, a citizen of the United States of America, and

resident of New York, in the State of New York, have invented certain new and useful Improvements in inhalers, of which the following is a specification.

This invention relates to inhalers for ad ministering anesthetics, and the ob ect of theinvention is to provide an improvement in inhalers and to make such inhalers more eflici'ent and simple and practical in use. Reference in thisconnection is made to my United States Letters Patent No. 892,717 of July 7, 190 in which an improved form of inhaler is shown. 7 i V The invention of this application is clearly shown in the accompanying drawing the regulating mechanism with the gas bag,Fig. 5 is a top-view of the regulating mechanism shown in Fig. 3, F 1g. is a longitudinal section taken on l1ne 6-6 of Fig.

. 3, Fig. 7 is a side-view of one of the tubes showing the connecting spring used in my improved inhaler, Fig. 8is a side-view of the anesthetic holder, Fig. 9 is a section of the structure shown in Fig. 7, and Fig.10 is a detail-view of the spring-clasp of Fig. 9, and which is also shown in Fig. 7. 1

Similar reference characters indicate corresponding parts throughout the different figures of the drawing.

Referring to the drawing, and more particularly to Fig. 1, the patient has applied a nose-cover 11, which is held in position by means of'the band 12 which passes around the back of the head and is adjustable by means of thebuckle 13. The nose-cover 11 is provided with an extension 7 3 to which is connected the regulating device'15. This regulating'device 15'governs thefiow ofair through tube 17. The tube 17 is held in position by the support 18, attached to a forehead plate 120. This support is adjusted by the thumb-screw 19 to set the'nose cover at different angles to fit different noses. The

forehead plate 120 has a spring-clamp 2O Specification of Letters Patent. Patented R1 28, 1916,

which extends to either'side of the forehead of the patient, and an'extension 21 which extends above and around the head of the patient to the clamping portion 22, which is arranged at the back of the head of the patient and which is engaged by the band 12. The tube 17 communicates with the member 25 to which is secured, by a conical friction joint, an extending member 26 having flanges 27, receiving between them the reinforced mouth of a rubber bag 28. This rubber bag is in communication with a device 29 into which a capsule of the anesthetic is placed, and in which the capsule is pierced and broken. When the capsuleis broken,

the gas is formed, and in order to take care of the large quantities of thegas so formed, the bag 28 is provided. The gas passes from the bag through the tube 17 through the regulating-device and thereafter into the nose-cover 11. The amount of said gas and the amount of the air necessary to be mixed therewith is regulated by the regulating device 15. I

The general operation as just described is well known; but one part of my invention consists inthe arrangement of this regulating device, and another part of my invention consists in the arrangement of the connectingspring which binds the various parts together; and a further part of my invention resides in having different nose-covers, which may be readily connected with the tube 14 of the regulating device by means of the spring connectionspoken of, and a. further part of my invention consists in having the head piece 20, 21 and 22 which has just been referred to, and further parts ofmy invention will appear in the description now to follow.

In Figs. 3, 5 and 6 is clearly shown the improved mixing-valve, the important feature of which is the septum which operates to permit the gas to be mixedwith the air and prevents the gas from passing out of the tube into the air, and at the same time also prevents too much air from entering into the device. The tube 14 has 'a sleeve 30 arranged at right angles thereto, and at the front of this sleeve a handle 31 is provided, which is secured to a shaft 32, which is socured to a disk 33 to which a sleeve 34 is secured. Sleeve 34 moves within the sleeve 30, and has a septum 35 extending diametrically across the sleeve 34. The inner sleeve 34 is provided with a disk 36, and the disks 33 and 36 serve to hold the inner sleeve'34' Secured to the sleeve" in suitable position. 34: is an indicating-fingerfi'? which operates over a scale 38, which is provided with suitable markings, as Air, 1/8, 1/4, 1/2,

etc, and which markings are arranged to in-" rl te v ses theep e f. th nte sleeve 3Q, which parts are clearly seen in Fig: gas Wi l p ss'frem h tu 17 to t e tube 14 and no air can enter, whereas when the port on has th i er s e e 3% only pe allyele s se epe g a r w l be perm t te pa s i to? the tube 1e from eutside of the tube through the opening 14:4 and mix with the gas. It Will also be seen that w e vhi1 is permitt o; enter',rt sep um will prevent the air form flowing in a backward direction into the tube 1 7 f nd at the same time the septum 85 will prevent the gas from passing outwardly into the atmospherieair. The flow of the gas from the tube 17 tothe tube 14: is indicated by the two arrows 4:6, and the flow of the gas from the exterior of the tube 14 into the tube 14 i i d c ed y h r ow .7, Henc byt e operation of the inner sleeve 3th With its Pert eh 3 an sept m 5, h ai a t see hy b prop r y i d t e ta nrep r ie s red nd ep ding P0 1 he tim el app ieetieh o th ae st e ie- As s.
