Speoication et Letters Patent.

Patented Juiy 29, 1913.

Application led April 20, 1811. Serial R0. 822,218.

To all whom it may concern:

Be it known that I, FRANCIS J. McSrinir, a citizen of the United States, and residing at Jersey Cit-y` in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Inhalcrs and Respirators, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to iiihalers and respirators and the object thereof is to provide a device of this class which is simple in constructure and operation and which is adapt- Aed for use by men and women whose occupa.

tions are such as to ex ose them to the necessity of breathing fou air: or uil' laden with acid, smoke, dust, grindings or any other injurious matter or substances capable of being drawn in through the n'ose or mouth in the operation of breathing; und with this and other objects in view, the invention consists iii a device of the class specified, con striicted and operated as hereinafter described andclnimed.

The invention is fully disclosed in the following specification of which the accompanying drawin forms a part, in which the separate parts o my improvement are designated by suitable reference characters 1n cach of the views, and in which Figure 1 is a back view of my improved inhaler and respirator; Fig. 2 a side view thereof with part of tbe construction broken away or in section; Fig. 3 a front view of the device; Fig. 4 a section on the line 4 4 of Fig. 2; Fi 5 a section on the line 5-5 of Fig. 4, an; Fig. 6 s. plan view of the device.

In the construction of my improved in` hater and respirator I provide a box-shaped bod portion a which is oblo in form in horizontal section and the en which are preferably circular in form, and said body portion is provided with a top or cap a and a. bottom a, and passed through the opposite end rtions of the bottom a are two similar t imbls-shaped members b the body portions of which are screw thresded, and with which are connected sleeves c the lower ends of which are provided with couplings d which are held in position by collars e screwed onto the lower ends of the Mounted on pivot pins a in the body a are levers f having intermeshing segmental portions of gear heads f2, and with the outer ends of which are connected valve rods g and It which extend downwardly through the sleeves c. The lower end portions of the -valve rods g and h pass loosely through spiders g2 and h in the sleeves c, and which form guides for the lower ends of said valve rods.

The pivot pins a* onwhich the levers f are mounted are rovided at one end with bearings in one si e of the body a, while the other end of said pins are pivoted in adjustable screw plu a mounted in the opposite sides of sai body, as clearly shown 1n Fig. 5, and by means of thisconstruction and by the use of set nuts, if desired the said pivot ins may be adjusted or held in place, as wi l be readily understood.

The thimble b through which the valve rod g passes is provided at its lower end with a port or passage i having an annular valve seat, and said rod g is provided above said port or passage with s valve i adapted to close the same.

The thimble b thi-ou h which the valve rod h passes is provide at the top th'ereof with a rt or passage j, and said rod h, is provi ed below said port or passage with a valve j adapted to close the saaie.

Connected centrally with the top a of the body a and communicating with said body is n tubular coupling k having a lock nut le, this connection being' a screw threaded connection, and connected with the coupling l.: is s main nipple coupling le' which is preferabl kspherical in form, and connected radis ly with the art k are two sleeve couplings Ic with w ich are connected supplemental nipple couplings k' in the to of which are of the a is also rovided centrally thereof wit a mouth mp le m having a tubular shank m adapte to be screwed into a collar m* formed on or connected with the bod a and, in practice, the device is manipu ated or held so that the nipple m will enter the mouth and at the same time the top portions of the nip les k may be inserted into the n0stri1s,.t e radial oonnections of the nipples k with the part k being such as to permit of this operation.

By securin the coupling lc to the body a by a screw t resded connection, provision il msdn for the vertical adjustment pf the nipples k' as will readily be seen. This con struction snsbles'ths operator to vary the orts or passages k. The ront their inner ends, and the nipples k are,

in the construction shown, slipped onto said couplin and by means of this construction the' sai nipples l may be adjuste'ditoward and from the part k* and the connection of the moutlrnipplc m provides foresimilar adjustment-thereof. These ad'ustments are found necessary to ada t the device for use by diterent wearers. he distance between the mouth piece and the nasal nipples, satisfactory an confortable to one person 'wil often have to be varied to render the device comfortable for another. So also the chances in the length of the mouth ieee or the distance of the same from the body of the device must be made to make the same comfortable to the wearer.

Connected with the couplin s dat the lower ends of the sleevesc are exible tubes n and o and, in practice, the tube n is carriedto a oint where a supply of pure air may be tained, and in the operation of this device fresh air enters throu h the tube n and this air after being breat ed is discharged through the tube o, and air passed outwardly through Lthe tube o may be discharged at any point.

The operation will"be readily understood from the-foregoing description when taken in connection with the accompanying drawin and the following. statement thereof.

i he construction and attachments of the mouth nipple and the nasal nipples are such that the said mouth niple ma befinserted into the mouth and the evioe.` ld in operative position byl this means alone, .or any preferredbridle `attaching device mayl employedl whereby the device may be secured to the head, and the adjustable feature' of the mouth and nasal nipples facilitates the use ofthev device, as .will-be readily understood.

In ythe o rationof breathing,`the air is4 drawnin, Iirough the. tube n and expelled th rougliI the tube o, svidair. passing into the lungs throu h .the hiouth and-nostrils and being expel ed therefrom in the usualway at regular4 intervalsp'andlas the air'flo'wts in throu h the tube nthevalve 'lkis'opened and tie valve y, closed and -as the air flows out through the tube o the valve j' is opened and the valve s closed.

With my improved iiihaler and res irator constructed and operated as described, it will be apparent that the impure air of the room or space in which the user-is employed cannot enter the lungs, as only ure air entering through .the tube-n can breathed through the nostrils and mouth.

My improved inhaler and respirator is' simple in construction and efiicient in operation and-may be used wherever such devices body, providedv with inlet and outlet aperare required, and the method of using the sameor the method of holding itin position for use may be varied according to the circumstances in each articular case or in any particular use to which the device is applied.

Haviu fully described my invention, what -,c aim as'new and desire to secure by Letters Patent,V is
