Specification of Letters Patent.
Patented July 25, 1916.
Application filed September 20, 1910. Serial No. 582,844.
1 '0 all whom it may concern- Be it known that I, SAMUEL VVARQ GREENE, of East Greenwich, in the county of Kent and State of Rhode Island, have invented certain new and useful Improvements in Respirators; and I do hereby declare the following specification, taken in connection with the accompanying drawings, forming a part of the same, to be a full, clear, and exact description thereof.
The invention relates to improvements in respirators, and has for its principal object to provide an improved and novel construction of respirator especially designed for use in the dangerous dusty trades inwhich a continuous current of fresh air is supplied to the nostrils of the user and the exhaled breath or vitiated air is expelled in such a manner as not to pollute the fresh air current flowing to the nostrils.
A further object of the invention is to provide a device of this character which is supported upon the head and will not interfere with or affect the sight of the user.
A further object of the invention is to provide a delivery nozzle having means for expanding the air current and causing it to flow against the upper lip directly beneath the nostrils and substantially at right angles thereto.
A. further object of the invention is to provide said air delivery nozzle with means adjacent the nostrils for the escape of the air current.
To these ends the invention consists of the novel form of respirator hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 is a side view of my improved respiratorin position on the head of the user. Fig. 2 is a top plan view. Fig. 3 is a vertical sectional view of the delivery nozzle.
In the drawings 1 represents the air-tube or conduit through which the fresh air is supplied to the delivery nozzle 2. The major portion of the air-tube 1 is preferably flexible and it is provided with a rigid end portion 1 which is adjustably secured to a spring head clamp 3.
Secured upon one side of the head clamp 3 is a screw-threaded post 1 which engages a slot 5 in the supporting member 6. The post 4 is provided with a thumb nut 7 for clamping the supporting member in position upon the head clamp 3. Said support ing member 6 is provided with a lateral extension 8 having a turned over end portion 9 in which is mounted an adjusting thumbscrew 10 which engages said lateral extension 8. The end portion 1 is secured to the bent over end portion 9 and is constructed and arranged to extend down the side of the face of the user, but not in contact therewith, to a point substantially in line with the lower end of the nose, and is then bent around the face so as to bring the delivery nozzle 2, which is secured to the free end of said end portion, in close proximity to the nostrils, as shown in Figs. 1 and 2.
The delivery nozzle 2 consists of a rectangular casing having the top 11, bottom 12, outer side 13, and end portions 14 and 15. The under side of the delivery nozzlenext to the face is open. The top 11 is provided with a recess 16 to receive the end of the nose, and the inner edge 12 of the bottom 12 is curved to conform with the curvature of the upper lip against which it is arranged to rest. The bottom 12 is provided with two inlet openings 17 and 18, one adjacent each end thereof and with a recess 19 on the inner edge 12 which serves as the outlet for the air current.
Formed or secured upon the under side of the bottom 12 between the inlet openings 17 and 18 is a longitudinally extending L- shaped extension 20 of the same width as the inner diameter of the end portion 1' of the air-tube 1. The tubular end portion 1 is provided with a closed end 21 and the upper half of said end portion 1 is removed for a distance equal to the length of the delivery nozzle 2. Said delivery nozzle 2 is then secured, preferably by solder, to the lower half of said end portion 1 so that the extension 20 forms a central partition for the end portion 1, as shown in Fig. 3.
Secured to the end portion 1 directly beneath the delivery nozzle 2 is an adjustablemouth shield 22 having arms 23 extending through openings in posts 24 and arranged to be clamped in position by thumb-nuts 25.
The operation of the device is as follows: The air flows through the air-tube 1 under any desired pressure and into the end portion 1. Upon reaching the extension or partition 20 the air current is divided, a portion flowing upon the upper side of said partition up through the inlet opening 17 and a portion flowing upon the under side of said partition up through the inlet opening 18. As the current of air flows up through the inlet openings 17 and 18 it strikes the top 11 and outer side 13 and is defiected toward the open inner side of the delivery nozzle 2 and against the upper lip of the user directly beneath the nostrils. In striking the upper lip the air current is further deflected'toward the nostrils when the user is inhaling and toward the outlet opening 19 when the user is eXhaling. With this construction it will be seen that there is a continuous current of air through the delivery nozzle flowing from the outer side to the face side, and that when the user is exhaling, the .vitiated air is expelled from the nozzle adjacent the nostrils, so that when he begins to inhale, all of said vitiated air will have been expelled from said nozzle and from the vicinity of the nostrils.
If desired additional outlet openings 26 may be formed in the ends 14 and 15 of the delivery nozzle 2, as shown in Figs. 1 and 2.
It will be seen that with my novel means for securing the right end portion 1 to the head clamp 3 the delivery nozzle 2 can be adjusted in any desired direction to fit the user. By means of the slot 5 the delivery nozzle can be raised or lowered; by turning the supporting member around the post 4:
the delivery nozzle can be moved laterally toward or away from the face; and by .means of the adjusting thumb-screw 10 the delivery nozzle can be moved longitudinally across the front of the face.
What I claim as my inventionand desire to secure by Letters Patent is:
1. A respirator comprising an air-tube having a rigid end portion .foi'medto extend.
down the side of the face and across to -the upper lip, a delivery nozzle secured to :the end of said rigid end portion, and .means upon the head, means whereby the delivery nozzle maybe adjusted vertically and laterally, and means for adjusting said deliv-,
ery nozzle longitudinally.
4. A respirator comprising an air-tube, a delivery nozzle secured to the end of said air-tube, a head clamp, a supporting member secured to the air-tube and mounted to slide and revolve upon a post secured to said head-clam) means for clam 3111 said sua- 7 I v I porting member in position, and a lateral extension upon said supporting member provided .with' a turned over end portion carrying an adjusting thumb-screw arranged to engage said lateral extension.
,5. A respirator comprising a rigid airtube having a closed end and a portion of said tube cut away, adelivery nozzle secured to said air-tube over said cut away portion, an extension upon the bottom of said delivery nozzle arranged to extend longitudinally within said air-tube and form a central partition therein, an inlet opening in the bottom of said delivery nozzle upon each side of said extension, and an air-outlet upon the face side of said delivery nozzle.
