VALVlE.
SPECIFICATION formingpart of Letters Patent No. 279,451, dated June 12, 1883. Application filcrl January 29, 1883. (NomodeLl To aZZ whom it may concern.
Be it known that 1, JAMES EDWARD SIN- CLAIR, of Baltimore county, State of Mary land, have invented a new and useful Improvement inYalves; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1. is a central longitudinal section of the valve. Fig. 2 is an end view from the end 0 of Fig. 1. Fig. 3 is a transverse section through the line m m of Fig. 1, looking in the direction of the arrow. Fig. 4. is a longitudinal section of a hand-pump, showin my valve applied thereto.
My invention relates to an improved valve, designed mainly for pumping or hydraulic purposes, but applicable to all uses in which a check-valve may be employed. It belongs to that class of valves in which an elastic or flexible tube is secured at oneend to a circular shell or ring, while' its other end is collapsed or flattened, which tube will allow fluids to pass in one direction, but acts as a check for the reverse flow;
My invention consists in making said collapsible tube in two parts, one of which is fastened peripherally to one end of a shell, and the other of which is fastened peripherally to the other end of the shell, while the two collapsible ends of said tube are fastened together, and one runs straight through the shell, while the other is folded upon itself.
It also consists in holding a collapsible tube both at its end and at its sides throughout its length to prevent it from doubling up, as will be hereinafter described.
In the drawings, A A represent a metal shell, in which is arranged the flexible tubing, made of canvas, rubber, or any other material. One section of this tubing, B, is fastened peripherally to one end of the shell by a clampingring, C, screwed to the end of the shell, and at this end is always distended or of circular form. This section of tubin g runs straight through or nearly through the shell, and at its other end it is collapsed or drawn by an elastic edge to a straight diametrical line, fornr.
ing a diametrical slit, as in Fig. 2. The other section of tubing, B, is secured peripherally to the other end of the shell by a clampingring,
C, screwed to the shell, and this section runs about half-way the length of the shell, and then, turning upon itself, has its free edge attached to the free or collapsed edges of the section B. This double construction of flexible tubing gives great strength to the valve, and when the water is checked it pockets in the folds of the section B and compels the section B to collapse at its end quickly. In a long collapsible tube of. this character the collapse of the tube will frequently cause the tube to become doubled up and become disarranged and inoperative. To prevent this I make the shell in two longitudinal divisions, A and A, with flanges a a, by which said divisions are bolted or screwed together. The flexible sections of tubing B and B are also each made in two longitudinal parts, and the edges of these longitudinal parts are caught between the flanges a a of the two parts of the shell and there firmly clamped in place. This, it will be seen, holds the flexible tubing throughout its entire length in the shell upon each side and effectually prevents any doubling up or any other objectionable action, and allows the valve to work perfectly and surely, with a normal opening and closing of its collapsible end.
In making use of this valve it may be connected with the lever of a hand-pump and reciprocated in fL 1:)I1Dl1)-bt1l'6l to raise or force water or it may be embodied in a steam-pump;
or it may be located in drains or sewers to act as a check-valve, and, besides these applications, is capable of very many other uses.
- The valve has packing and rings at each end, which give steady and easy motion to the same,
and the flexible tube opens to the full area and conforms to the shape of the inside of pump, no matter whether round, square, or oval.
When the valve is used in connection with a hand-pump, as shown in Fig. 4, said valve is provided with studs pp on its opposite sides, near its middle and between the packing at the ends of the valve, and these studs play through slots in the side of the pump-cylinder, and constitute a point of attachment for the forked lever (not shown) which recipro cates it. To make an operative pump a stationary valve is arranged, as usual, in one end of the pump-cylinder, which maybe the same construction as the movable valve, or any other desired construction. The movable valve has also at each end a flexible and collapsible tubing, 1, of canvas, which is connected to the ends of the cylinder, and forms a straight continuous passage for water, which prevents grit from getting into the wearing parts of the cylinder.
Having thus described my ll claim. as new is- 1. A valve composed of a shell or frame having within it a collapsible tube-section, 3, running straight in the shell, and secured peripherally at one end, and a collapsible section, B, secured peripherally at the other end, and re turned or folded upon itself, and having its free end connected to the free end of the other tube-section, substantially as described.
