VALVULAR ARRANGEMENT FOR DIAPHRAGM-PUMPS.
Speccation of Letters Patent No. 11,300, dated July 11, 1854.
To all whom t may concern:
Be it known that I, STILLMAN A. CLEMf Figure l is a perspective view of the outside of the pump; Fig. 2, a sectional elevation of the same, and Fig. 3, a perspective representation of some of the inner parts of the pump, with the valves, .&c., a littleseparated from each other, but in their proper relative position one above the other. Figs. 4, 5 and 6 represent modifications of the pump and parts.
The same letters refer to like parts in each figure.
(a and b) Figs.` l and 2 are the two shells or hollow parts which form `the body of the pump.
(c) is the pump lever which in Fig. 2 is represented with the handle down.
(d) is the lever stand or fulcrum which forms at its attachment to the top of the pump a packing boX for the pump rod (e). The upper and lower shells of the" pump are united by flanges, between which is se cured the periphery of the diaphragm, which is represented at (f). Above the diaphragm and secured t-o the pump rod by a nut on its upper side is a perforated disk (g), which has a hub or washer extending downward from its lower face and lying upon the diaphragm (it), where the pump rod passes through it. Below the diaphragm is a. disk (i), which is without perforations and is secured to the pump rod by a nut below. That part of the diaphragm which is within a circle covered by the lower disk is perforated, andthe lower disk in connection with the perforations in the diaphragm form a valve. i
is a check valve made of a circular piece of metal, faced with leather on its lower side for packing, and provided with wire pins projecting downward to keep it over its seat on the top of the inlet tube (lo), which last is represented .with a screw on its outer surface by which the pumpis connected to the supply pipe (Z). On the upper)part of the pump is the discharge pipe The diaphragm is made of leather or any suitable material, preference being had to that which has flexibility with sufficient strength, and has but little elasticity eX- cept by compression on its surface. It is so mad'e and applied that it has a bagging or basin form within the circle of its attachment to the flanges of the upper and lower parts of the pump, to give sufficient capacity to its piston action as the pump rod is, raised and depressed.
In Fig. 2 the handle of the base is rep-resented as down, and the pump rod and the parts to which it is attached on the inside are raised. The upward movement of the pump rod firstraises the lower or valve disk against the lower surface of the diaphragm (h) and closes the perforations in it which prevents the escape of the water downward. The diaphragm then rests upon the valve f(i), which, together with the `water on its upper side, is raised, andthe latter is forced out of the discharge pipe. Thile this upward movement is made, the water from the supply pipe raises the check valve (j) and fills the space below the diaphragm. Vhen the upward motion ceases, the check valve closes by its own weight and prevents the return of the water into the supply pipe. As the motion of the pump rod is. reversed it first .withdraws the periphery of the valve disk (i) from its contact with the lower side of the diaphragm, which uncovers.` the perforations in the latter, and the periphery of the upper perforated disk (g) is brought down upon the diaphragm, which depresses it, and causes the water from below to pass between the outside of the valve disk (i) and the diaphragm, and thence through the perforations in the latter and in the upper diskinto the space above.
Figs. 4, 5 represent a pumpin which the same principle of action is applied to the valve and diaphragm as in the one just described, but under a difference of monstruotion. (In Fig. 2 the valve is seen at a1 below the diaphragm and is firmly fixed to the piston rod a2. Thediaphragm in this case is held between the edges of the disks a3, at and the valvular openings are in the disks which may be regarded as a part' of the diaphragm, and the disks together with the diaphragm have play up and down the pisand the valve being attached to and Worked by the piston in such manner that the diaphragm shall move to and from the iXed valve and close and open theJ holes in the l diaphragm valve substantially in the manner set forth.
