UNITED STATES PATENT OFFICE..
GEORGE NV. NTZ, OF4 PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO` HENRY D. JUSTI, OF SAME PLACE.
INHALER.
SPECIFICATION forming part of Letters Patent N'o. 433,418, dated July 29, 1890.
Application tiled March l0, 1890. Serial No. 343,387. (No modeL) To all whom it may concern:
Be it known that I, GEORGE WV. NTZ, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Inhalers, which improvement is fully set forth in the following specication and accompanying drawings.
My invention relates to improvements in inhalers for administering aneesthetics; and it consists, first, of a body or shell in the form of a single tube with a side opening, a sliding tube having a closed end workingin said body or shell and provided with an opening adapted to register with the opening in the body or shell, and a check-valve at the inner end of said tube and connected therewith, and, second, of the general construction, arrangement, and combination of the parts, as will be more fully hereinafter described, and pointed out in the claims.
Figure l represents a perspective view of Fig. 2 represents a view of avertical longitudinal section of the device shown in Fig. l in reversed position.
Similar letters of reference indicate corresponding part-s in the two figures.
Referring to the drawings,A designates an inhaler having the shell or body portion B formed of a single tube, so as to avoid a joint in the same between a check-disk at the inner end of the valve C and the gas-supply pipe. Fitted into one end of the shell B is a hollow cap E, which forms a bearing for the stem F ot the valve C. The valve-chamber D of the said valve C is formed of a tube G, having an opening ll in its side adapted to register or communicate wit-h an opening J in the shell B. Surrounding the opening J and connected with the shell B is a rim K, to which is secured an attaching device L for a pipe or hose leading from a bag or other gas supply.
The end of the tube G which is connected with the stem F is closed and the other end is provided with an opening Ifl,which is covered by the checkwalve disk M, the latter be ing controlled by the guides N, which are attached to the open end of the tube, forming a cage.
Connected with the outer end of the stem F is a knob P, having a tubular portion Q, adapted to slide within the end of the cap E, and within the cap E and tubular portion Q and encircling the stem F is a coil-spring R, bearingagaiust the knob and adapted to keep the valve C closed against the admission ot' gas.
lVithin 'the shell B and between .the 1n0uthpiece S and the valve C is an eXhalation-valve T, having seats for its disk U on the flanged rim V ot a boss WV, formed on the inner side of the shell B, and on the projecting arms X on the inner side of the said boss.
On the shell B and between the collar K and the face-guard or shield Y is a collar or sleeve Z, having a series of openings A', which, in connection with a coinciding open` ing B in the shell B, aitords communication between the chamber of the valve T and the atmosphere. The collar Z has also a series of openings C communicating with the interior of the shell B by means of an opening D', which latter is closed when t-he valve C is pressed inwardly for the admission of the gas, but open when the gas is not being administered. The said openings C and D', when uncovered or open, permit the entrance ot the air to the interior of the shell and to the mouth without it passing through the gassupply valve C. The walls of the openings A and C are inclined, so that air passing from them is not directed against the face of the party using the inhaler, which is a great advantage, as is well understood to those accustomed to use the device.
The operation of the device is simple and easily understood, and is as follows: The mouth-piece S being inserted in the mouth of a party so that the shield Y is against the face, the receptacle containing the gas being connected with the attachment L, the valve C is then pushedin by means of the handle or knob P on the end of the stem, so that the opening H will register with the opening J and thus permit the Iiow of the gas into the chamber D of the valve C. The gas pressing against the disk M forces it off its seat, so that the gas passes through the opening H and around the said disk to the mouth-piece and thus into the lnouthof the user. Vhen the valve C is pressed in, the opening D is closed, so that any escape of the gas through the openings D and C is prevented. The valve T permits an exhalation to pass to the atmosphere without closing the valve C, the disk M, however, being closed or seated, so that the air does not pass into the valve-chamber D. When asufcient quantity of gas has been inhaled, the pressure is removed from the knob P, so that the spring R forces the valve outward, thereby closing the openings H and J, thus stopping the further iniiow of the gas. If, now, an exhalation is desired without removing the device, the exhalation from the mouth enters the shell A and a part passing into'the chamber of the valve Traises the disk U, so that it escapes through said chamber and the openings B and A to the atmosphere. The openings C and D being also open, a portion of the exhalation also escapes therefrom, and as the walls of said openings A and C are inclined from the user the eX- halation in passing out to the atmosphere is not directed against the face.
Owing to the shell B being of a single tube and without any joints therein, there is no leakage of the gas between the gas-supply opening and the mouth-piece, as is readily seen.
By forming the seats of the exhalati'onvalve on the inner side of the shell, instead of on the outer side, a'better protection is afforded them against injury, and at the same time a projecting portion is avoided.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. An inhaler having a body or shellfconsist-ing of a single tube with an opening in its side, a sliding tube closed at its outer end and working in one end of the said shell andhaving an opening in its side adapted to register with said opening in the side of the shell when the tube is pushed inward, and a check-valve at the inner end of the tube and connect-ed therewith, said parts being combined substantially as described.
2. An inhaler having a shell with an opening in its side for the gas-supply, a sliding valve-chamber with opening adapted to register with the said opening in the shell, a check disk or valve at the open end of the valvechamber, and an exhalation valve having seats within the shell and provided with a discharge-opening in the said shell, said part-s being' combined substantially as described.
3. An inhaler having an eXhalation-valve provided with seats on the inner side of the shell thereof, and provided with a dischargeopening in the side of said shell, substantially as and for the purpose set forth.
4. An Vinhaler havinga shell with an opening` in the sides for the gas-supply, a sliding valve-chamber with a side opening adapted to register with said gas-supply opening in the shell and having a check-valve at its open end, and an exhalation-valve having its seat within the shell, said parts being combined substantially as described.
5. An inhaler having a shell or body portion with a side opening in the same for the gas-supply, a sliding valve-chamber with a side opening adapted to register with said gassupply opening in the shell, and a collar on the shell having openings coinciding with openings in the shell, the walls of said openings in the collar being upwardly inclined and away from the mouth-piece end of the shell, said parts being combined substantially as and for the purpose set forth.
6. An inhaler having a shell with an opening in its side, a sliding tube with a closed outer end and having an opening in its side adapted to register with said opening in the shell, a check-valve connected with the inner end of said sliding tube, a collar on the shell near the mouth end thereof and provided with openings communicating with openings in the shell, the said openings in the collar having their walls inclined away from said mouth end of the shell, said parts being combined substantially as described. n
7. An inhaler having a body or shell with an opening' in its side, a rim surroundingsaid opening and secured to said shell, a sliding tube with a closed outer end in said shell and having an opening in its side adapted to register with said opening in the side of the shell, a check-valve connected with the inner end of said tube, a collar surrounding said shell at or near its month end and having openings therein coinciding with openings in the shell, the walls of said openings being inclined from the said mouth end of the shell, and an exhalation-valve with its seats within the shell, said parts being combined substantially as described.
