TU ALL WHOM ITl MAY CONCERN:
Be it known that I, SAMUEL W. SINE, of Easton, in thc county of Northampton, and State of Pennsylvania, have invented a new and improved Iuhaling-Tube; and I do hereby declare that the following is a full, clear, f
and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
This invention relates'to an instrument which is used for i haling gas or anaesthetic agents, for producing insensibility in surgical, dental, and other operations, or for other purposes; and it consists in providing and operating metallic valves inv a suitably formed inhaling-tube, as will be hereinafter described;
Figure 1 represents a longitudinal central section of the instrument. showing the manner of its construction and the position of the valves. 'n l d Figure 2 is a cross-section through the line a: a: of iig. 1.
Similar letters of reference indicate corresponding parts. l
A represents the tube, B is the mouth-piece, C is the'stop-cock. D is a valve on the end of the tube, which opens inwardly or when inhaling. E is a valve in the stop-cock C, which opens outwardly or when exhaling. The gas-pipe is attached to the tubeat the'end D.
In the instruments hitherto used for the inhalation of nitrous oxide or other gas, for the purposes before mentioned, the valves have been made of fine elastic material, which, during the inhaling operation becomes covered or saturated with moisture,.which renders them liable to stick and become inoperative, especially at the time when the patient is losing consciousness or falling into the aneesthetic state. The respiratory organs at that time become relaxed, requiringvalves of the most delicate description -to allow of the prop er action ofthe instrument. l Y l From experiments made, with the design to overcome the diiiculty with the elastic valve, I have found that the lightmetallic valves, aided by delicate metallic springs, arranged 'as shown in the drawing, obiates all diilculty. Y
The valv-e E is formed of silver, or other suitablevmetal, covering the orifice through the metallic diaphragm c, in the metallic thimble F ofthe tube, as seen in the drawing. The valves are attached to the thimbles F by hinges which form a stop, thus preventing their openingl beyond a certain point, as seen at e. Thevalves. are arranged in thimbles for the purpose of adjusting them to the tube with greater facility. In metallic tubes the arrangement might be different. Y
For the purpose of assisting the valves in opening, or to insure their perfect operation, Lplaco metallic springs behind one or both of them, as seen at clin the drawing. In the 'example shown, the spring isonly seen behind the valve E. The peculiar form and construction of this spring is seen in fig. 2, attached, t0 the diaphragm c. v
Having thus described my invention, I claim as new, and desire .to secure by Letters Patent- A 1. '.lhe metallic valves D and E, the .diaphragm c, stop e, and spring d, in combination with an inhalingtube, substantially as and for the purposes described. 2. Ametallic valve, either with or without a stop and spring, in combination' with an inhaling-tube, substantially as described. v
The above specification of my invention signed by me, this 6th day of September, 1867. A
