RESPIBATOR.
Specification of Letters Patent.
Patented Apr. 3, 1917...
Application filed July 11, 1916. Serial No. 108,741.
To all whom '52 may concern:
Be it known. that l, J. A. STE MARllfi, a subject of the King of Great Britain, residing at La prairie, in the Province of Quebec and Dominion of Canada, have invented new and useful lm n'ovenients in Respirators, of which the following is a specification.
The invention relates to respirators, and has for its primary object to provide a device of this character wherein "fresh air can be inhaled from without while within an inclosure without ossil.-ility of the inhalation of dirt, dust, snow or foreign matter.
Another object of the invention is. the proi ision of a device oil. this charm'zter wherein the construction thereof is novel in form so that the breathing of a person can be effected naturally and during; respiration. fresh air will be. inhaled for passage into the lungs of the user.
I A further object oi the invention is the provision of a device oil this character which is extremely simple in eonstructimn thoroughly reliable and cilicient in its operation, strong, durable and inexpensive in menu facture.
Other objects will be in part obvious and in part hereinafter set forth.
The invention accordingly consists in the features of construction, combination of eleinents and arrangement of parts which will be exemplified in the construction heroinafter described,'and the scope of the application of which Will be indicated the up pended claim.
In the accompanying drawings:
Figure 1 is a side elevation of a respirator constructed in accordance with the inventiou;
Fig. 2 is a Vertical. longitudinal. sectioruii view through the respirator hood Fig. is a vertical sectional vii-w through the inlet cap;
Fig. t is a sectional view on the line that of Fig. 2;
Fig. 6 is an, end elevation of the hood.
Simila r reference chain 8 indicate corresponding" parts throu rent the several views of the drruvings.
Referring to the drawings in detail, the respirator comprises a substantially cone shaped body 10 forming a hood having at one end a nipple 11., whiie i s opposite open end 32 is formed with a nose bridge 18, the
Fitted over the nipple 11 of the hood 10 is one end of a flexible tube 1 1 which has mounted on its opposite end a conical shaped ca p 15 which is held spaced from the inlet end of the tube 141 through. the medium of a spider 16 so that air can be sucked in through the inlet nd of the tube into the body 10 when the respirator-is in use. It is of course umlcrstood that the inlet end of the tube 14 extended without an inclosure' for communication with the atmosphere so that fresh or pure air can be inhaled for passage into the lungs of the user. The cap 15 serves to protect the inlet end of the tube 14; and also in this inlet end is a gauze screen 17 which prevents the ingress of dust, dirt or other foreign matter during inhalation. The nipple 11 is formed with a central bore or pas- 18 which has at opposite ends thereof guides 19, in which is slidably mounted the stem 20 of a disk valve 21 which is adapted to open inwardly of the body 10 to permit the inhaling of fresh air, the stem 20 being surrounded by means of a coiled spring 22 which servesto normally hold the valve 21 closed or seated against the inner end of the bore 18 in the nipple 11. The stem 20 is formed. with a stop 23 which limits the slidingr HOSGilliPDt thereof in the. guides 19 so as to-liinit the opening movement of the valve when the device is in use.
P06111011 t the lowermost side of the body or hood 10 an outlet nipple 24: having a bore provided at opposite ends with guides 21: in which slides centrally thereof a valve stem 27 rarryiu a disk valve 28 which opens outuardl of the body or hood 10 and is mirmally sr 2d upon the outer end of the nipple 2:4: to ClUSi same. The stem 27 has surrouml" a spring 29 which nornmlly seats e "8 and on the expelling at air throng strils or nose of the user the valve is automatically un ion of the air from the body or an; respiration.
F'tted 'le 24 is a foraminous or wire nu h cap forming a guard 24: for the valve 2?: so as to avoid any interference with the Working of the valve from without the device, that .is to say, the guard or cap 24;
envelope the valve to protect it from contact with external objects and especially when the device is in use by a person when occupying a bed. to obviate the bed covering interfering with the Working of said valve, as will be obvious.
Having thus described my invention, I claim: 7
A respirator comprising a hood having an open end shaped to receive the nose and mouth of the user, nipples formed at spececl points on and projecting outwardly from the hood, valve seats carried by the respective opposite ends of the nipples, valve stems operating through the nipples and having valves to engage the valve seats, means arranged Wholly Within the nipples to maintain the valves normally seated, and coopersting means carried by the nipples and valve stems to limit the opening movement of the valves, each of the nipples including a cylindrical free projecting portion to receive atube,
In testimony whereof I aflix my signature.
J. ALPHONSE STE MARIE.
