. IMPRovnMnN'r m VALVES Afr THE Enns or TUBES.
The Schedule rei-'erred to in the Letters Patent and making part of the same.
To all whom it concern.-
Be it known that I, J. n. Himnos, Vnun., of Dex! ter, in the-county of Penobscot, and State of Maine, have invented anew and useful Improvement inValves and Valve-Holders, for surgical and other instruments; and I do hereby decime the following to be a'full, clear, and exact description of the same, reference being had to the drawings accompanying this'speciiication, and forming a part of the same, andto the figures 'and letters thereon, in which I Figures 1 and 2 represent perspective views of my apparatus.
Figure 3, a vertical section of iig. 2.
Figure 4, a vertical section of the valve-holder.
Figure 5, a vvertical section of the valve.
My invention relates to an improvement in valves and valve-holders, which is adapted to a great variety of purposes, such as for surgical-instruments, breast and stomacl1-pumps, cupping-glasses, cow-milkers', air and other pumps; in short, it' may be used wherever liquids or gases are to be passed throughtubes. It is very simple inits construction, easily made and applied, not liable to get out of order, has no wearingsurfaces, and makes a most perfect air and water-tight valve.
In order that others may -be enabled to make and use my improved valve and valve-holder, I will proceed to particularly describe it.
A, iig. 1, is the valve-holder, inserted in the lower end of the pipe or funnel B, and having the -valve O on its lower end, in which position liquids or gases would be permitted to pass downwards only, the valve G instantly closingY by the contraction of itsfibres when the pressure is removed.
' valveholderA is made ofany suitable material, and is shown in section at figs. 3 and 4. The end at Aer is made cylindrical, for nearly one-third of the. whole length, to receive upon it the ring or open end of the valve C, and below this it is made somewhat larger, and a screw-thread is cut upon its srn'face, to retain the end of the pipe or funnel B, as shown in iigs. 2 and 3.
Below this screw-threadis a flange, b, extending around the holder, to preventthe funnel or tube'from going on too far, and the lower end, .at c, is made the lower frustum of a cone, the base 'being downwar( as shown in the diiierent figures. This is for the pr pose of receiving and retaining the end of the pipe vfunnel firmly upon it, when in the position represent at iig. 1. l
A hole is drilled through the valve-holder longrt Idinally,'so as to admit of the free passage of liqui or gases.
The valve G,as constructed, is a hollow Indiafrubh tube, iirst made with one end closed. Anincision then made, a short distance belowthe inner surfa of the closed end,with a sharp instrument, so as leave about onethird of the inner surface of the tu inta/ct. The incision is continued back externally, 1 minishing in depth, leaving the fibres gradually thick on each side.V Thevalve thus constructed admitsA fluids or gases passing through it by the extension a contraction of its iib'r'es, and always remaining clos when no force is acting on it.
I am aware that valves have beenconstructed sin lar in appearance to that above described. However critical philosphical examination of its structure, sho it to be unique in this particular, that when perfe it acts in all positions, irrespective of its weight, i construction counteracting the force of gravity. Bei:
. made of partially-vulcanized India rubber, the contre tility inhering in the material corresponds to the mr cular or vital force that governs the valves of the h man heart.
The mannerinwhich it is constructed, and the for inhering in the material, (to which no claim is mar apart from the precise construction,) makes it, fro
necessity, an accurate, sensitive, and reliable valve.
