Description

'UNITED STATES JACOB O. JOYCE, OF DAYTON, OHIO.
\ IMPROVEMENT IN FORCE AND VACUUM PUMPS.
Vthe pump. The second part of my invention relates to the construction and arrangement of a check-valve within avalvechamber, which acts as a strainer.
Figure 1 is a perspective view of the upper valve-chamber. Fig. 2 is a perspective view p p the check-valve chamber for the induction of of the lower valve-chamber with the ports andv passages leading to the discharge-chamber- Fig. 3 is a vertical section of Figs. 1 and 2 on the vline x x. Fig. 4 is a vertical section through the center of the check-valve chamber.
The other parts of the pump, not shown in the drawing, are fully described in Letters .Patent granted to me November 10, 1868, and it is not necessary to describe them here. The ports and passages leading from the valvechambers to the piston, air, and discharge chambers are also the same as described in my said patent.
A represents the upper valve-chamber, with the removable top c a removed. a. a a a represent holesA with threads for screws which fasten on the top. B B represent valves, attached to gudgeons b b at their top, as shown -in Fig. 1, and placed at an angle of about forty-five degrees, the inner journals of the valves bearing on the partition b. c c are screws, which secure the packing to the valve. D is the lowervalve-chamber, and is a part of the base of the pump, the piston and air-chamber being removed,the valves E E being hinged and arranged as shown in Fig. 2. Iis the suction and discharge passage leading from the valve E. H is the suction and discharge passage for the valve E. G G are discharge-pas sages leading' from the upper valve-chamber to the ednction-pipe. ff are ilan ges for connecting the partsAA and D together by means of screws or bolts passing through the holes t t. V is the check-valve chamber, which is connected to the induction-port in such manner as to stand upon the base T', placed at the bottom of the well, and is divided into two parts', n n', connected by screws in the ilanges o o. p is a diaphragm, shown here as connected to the bottom of the valvechamber n', but it may be attached to the top part, if desired. r is a valve seated on the diaphragm S S represent holes in the lower. part of 1. The valve-chamber A, composed of the v removable top a', with the inclined hinged valves B B with journal-bearings b b and partition and bearing b', in combination with the chamber D and port G, all arranged substan-` tially as set forth.
2. The improved check-valve and chamber V, composed of the parts n n', diaphragm pp, valve r, orifices s s, and base T, all combined and arranged substantially ,as set forth.
