INHALER.

SPECIFICATION forming part of Letters Patent No. 279,265, dated June 12, 1883.

. Application filed May 3, 1883.

To allwhom it may concern Be it known that I, LAIRD W. NEvIUs, a citizen of the United States, residing at Toledo, county of Lucas, and State of Ohio, have invented a new and useful Improvement in Gas- Inhalers, of which the following in a specification.

The inhalers now in use have the exhalingvalve on the upper part of the-mouthpiece or on the inhaling-pipe, so that the gas used by a patient is discharged in an upward direction. This exposes the operator to the effects of the impure gas and renders its administra tion in a certain degree injurious to health.

The object of my invention is to provide a simple and effective inhaler free from this ob je'ction, and one that will have the additional advantage of being'held to the mouth and operated up on by a single hand, leaving the other free for instant usewhen a sufficient quantity of gas has been administered. I secure these advantages by combining with the mouth-piece of an inhaler an exhaling and inhaling tube having suitable valves for the inspiration and expiration of the breath an d gas, the exhalingtube being so placed upon the mouth-piece as to project horizontally therefrom, and, by means.

of the exhaling-valve at its end, securing, with each expiration of the breath, the discharge of the gas in a line, as near as possible, to the line of the breath from the mouth. The inhaling-tube is provided with a slide-valve having a rubber seat, said valve acting by pressure upon its head, opening thereby, and closing by means of a rubber or spiral spring attached to the valve-slide and fitting over the inhaling-tube.

Figure 1 is a sectional view of my inhaler. Fig. 2 is a cross-section of inhaling-pipe, drawn upon line 40 in Fig. 1, showing slide-valve Fig. 3 is a cross-section of inhalingpipe, drawn upon line a in Fig. 1, showing slide-valve opened.

Similar figures of reference indicate corresponding parts,

In Fig. 1, 2 is the rubber mouthpiece, which fits close to the face; 3, the metallic collar or hood into which the mouth-piece fits; 4, the horizontal, exhaling-tube 5, the exhaling-valve at the end of said tube; 6, the cap, with central opening and perforated sides, fitting over (No model.)

and protecting the exhaling-valve; 7, the inhaling-tube; 8, the inhaling-valve; 9, the slidevalve 5 10, a section of rubber tube fitted within the inhaling-pipe and forming the seat of. the slide-valve. i

In Fig. 2, 9 is the slide-valve in a closed position; 11, the opening; 7, the inhaling-tube; 12, the rubber or spiral spring fitting around the inhaling-tube and held in position by the grooved shoulder 13 on the end of the valveslide. I

It will be seen by the construction shown that the gas, after being used, will be discharged in a direction away from the operator, and that the inhaler can readily be held and operated up on by one hand. By taking it in either hand, the operators thumb or finger upon the head of the valve-slide, it is ready for the administration of gas. Pressure upon the slide will bring the opening 11 (shown in Fig. 2) in a line with the inhaling-tube, as shown in Fig. 3, thus allowing a free flow of gas from the receiver. \Vhensufficient gas has been administered, removing the pressure from the slide or dropping the inhaler instantly cuts off the supply of gas. In Fig. 3 the valve is shown as open.

By placing the exhalingw'alve in, the line of the breath from the mouth I not only secure protection to the operator, but the best possible action upon the exhaling-valve by direct pressure with each expiration of the gas, said pressure at the same instant closing the inhaling-valve located immediately below it.

The exhalin g and inhaling tubes form a junction at the neck of the mouth-piece, which they enter in the form of a single pipe.

The mouth-piece should be of rubber or other flexible material, the hood around its neck, the inhaling and exhaling pipes, and slide-valve should be of metal or other suitable material, and the exhaling and inhaling valves of thin rubber. Sections of rubber tube properly fitted within. the pipes will form the necessary valve-seats.

The slide-valve operates through and across the inhaling-tube by means of slots on either side of the tube, through which the slide moves. At the end of the slide opposite the head, where pressure is to be applied, is a grooved shoulder, into which the rubberring or spring is placed to hold it in proper position upon end, protected by a cap havinga central spring, the tube. said pipe projecting horizontally from the neck Vhat I claim as my invention, and desire to of the mouth-piece, and forming a junction I 5 secure by Letters Patent, iswith the inhaling-pipe near its base, substan- 5 1.

Nevins, of Toledo, Ohio, for an improvement in Inhalers, an error appears requiring correction as follows: the Word spring, in line 5 of the second clause of claim of the printed specification thrilling at part of said patent, should read opening, and that the specification should be read with this .eorreetion therein to make it conform with the record of the case in the Patent Offiee.
