Specification of Letters Patent.
Original application filed October 1, 1908, Serial No. 455,718. Divided and this application filed November 5,1912. Seria1No.729,673.
To all whom it me concern.- I
Be it known t at I, JOHANN HEINRICH DRKGER, a subject of the Emperor of Germany, and resident of Liibeck, in the Ger-v man Empire, have invented certain new and useful Improvements in Artificial-Breathing Apparatus, of which the following is a specification, and is a division of my application for which Letters Patent of the United States were granted January 7, 1913, under No. 1,049,346,
The present invention relates to improvements in methodsand apparatus for. artificially causing people to breathe. By the aid of a breathing apparatus air or some other suitable, gas 18 forced into the breathing organs'of the body and then drawn out again by suction in a way similar to natural breathing. A paratus of this kind. known heretofore di ers from the present apparatus inasmuch as in the present'apparatus' the air or gas conducting means for the alternate connectionwith the breathing organs are so arranged that the same gas driving means is used both for producing the inhaling as well as the exhaling. -The pipes used are connected with a pressure and suction device in a manner to secure a reliable operation.
In thedrawings similar letters refer to snmlar parts.
.Figure 1 is an elevation of an apparatus constructed according to this invention.

Fig. 2 isa front view of the same partly'in section. Fig. 3 is a plan.- Figs. 4 and 5 are diagrammaticalviews of the air or gas conducting means. Figs. 6, 7, 8 and 9 are diagrammatica'l views of modifications of the last named means.- Figs. 10 to 12 are elevations of an apparatus in three positions for operating the modification shown in Figs. 6 and 7.
In the apparatus shown in Figs. 1 to 5 a designates an oxygen (or other gas) flask having as usual an outlet valve b and reducwhich by means-of piping herein'after described'is connected with a mask 8.
The reducing valve 0 1s provided with an e ector or nozzle dfrom which two pipes f and e lead to a valve for instance a fourway cock or valve z'as shown. 'The latter is preferably connected with a breathingmask s by a flexible pipe 9 and is provided with a short pipe h leading out into the open air.
The mask 8 may be dispensed with as. the
pipe 9 may be held in the mouth, or nose pieces may be provided. Thus the gas ejecting from the nozzle (1 under pressure passes Patented Apr.2, 119115.
either with the pipe f or with "the pipe (3.. i
The result is that the breathing organs of the person to whom the mask is attached are alternately. given oxygen (or gas) ejected from the opened valve 6 by the nozzle (1 together with air by the pipes 15., e, f, g or the bad-air is drawn from them by way of pipes g, e, f and 72,.
he change of position of the cock may be effected by any suitable means, for instance a motor may be provided to oscillate the cock. In the construction shown in Figs. 2 and 3 the motor comprises a clockwork ;0 for rotating a shaft 1', to which is fixed a cam disk m. A lever l is pivotally connected with a stud 0 and is provided with a pin 1, which projects into the cam slot n of the disk m. The lever Z is connected clearly shown in Figs. 4 and 5.
As may be seen there is not a special ejector forthe inhaling and a special ejector 95 y for; the exhaling, but both operations are carried out by one single nozzle, which operates in connection with pipes f and e.-
- In the construction described above it will be preferable to'make the flexible pipe lead.
ing-to the mask as short or small as possible enter the .mouth again. However it is gen- 10o .so as to allow very little air breathed out to a p 1 erally advantageous and frequently neces- I sary to use pipes that are notftoo long or too small. In the modifications shownin Figs. 6 to 9 two flexible pipesare shown one g for the inhaling and the other 9 for the exhaling.
In the modific'ation'shown in Figs. 6 and7 ed to direct said air out of the pipe through the pipes e and f are connected with an one of said openings and thereby create a open ended cylinder k having a piston rod t suction through the other opening, and a carrying three pistons, which may bebrought branch pipe communicating with one of said into two positions.
