IMPROVEMENT IN STE Specification forming part of Letters Patent No. 1 July 11 AM VACUUM-PUMPS.
81,652., dated August 29, 1876; application filed ,1876.
To all whom it may concern Be it known that I, WILLIAM V. DUBoIs, of Oovington, in the county of Fountain and State of Indiana, have invented a new and Improved Vacuum-Pump, of which the following is a specification:
My invention relates to the construction and arrangement of the working-chambers, air-chambers, and valves, and particularly to the contrivance of the valve for changing the admission of steam to the working-chamber, and to a vacuum-chamber for relieving the jar at the footvalve in the end of the pipe in the wall.
Figure l is a sectional elevation of improved vacuum-pump, taken on the line 00 a: of Figs. 2 and 3. Fig. 2 is a plan of the inverted middle section of the pump. Fig. 3 is a plan of the base-section, and Fig. et-is a section of the top of the pump.
Similar letters of reference indicate correspondin g parts.
A is the base-section of the pump, mounted on legs B of any approved form, and having the suction-inlet 0 made in the middle of it; also, a discharge-pipe, D, for the water, if desired; or the discharge may be at the top E. On the top of this base-section. are clackvalves F, admitting water from the suction into the working chambers G, and from the base of these chambers some of the water is forced by the steam through the clack-valves 1 into the air-chamber J, while the rest isforced through valves K into the dischargechamber L, from which it may escape either through the port D or E, one being plugged up when the other is used. Steam enters the Working-chambers from the chest M through ports N, being cut off from one and let into the other by the double-rockin g clack-valve O. P represents jet-pipes from the air-chamber J into the working-chambers, to condense the steam and make the vacuums. The vacuum in one chamber holds the valve 0 down on that. side, and admits steam into the other chamber containing water. The steam forces the water out through chamber L, and also passes some of itinto the air-chamber J against the airspring therein. When the water is all forced out, and the steam finds full exit by the valve K, the pressure so diminishes that the airspring throws a jet into the empty chamber G, condensing the steam and forming a vacuum therein, which reverses the valve 0, so that the empty chamber fills, and the full one empties. The valves F and K are in this case pivoted by connection with a rubber disk, R; but,in practice,I propose to arrange them with pivot-studs, one at each side, to be secured by staples titted in the bed or seat. S is a vacuum-chamber, connected at T with the suction-pipe, to cushion the water and prevent jar at the foot-valve by the changes of the suction from one chamber toanother.
Having thus described my invention, I claim as new and desire to secure by Letters Pat ent 1. In a vacuum-pump, the combination of the working-chambers G, air-chamber J, discharge-chamber L, jet-pipes P, vacuum-chamber S, valves F I K, and the double-rocking clack-valve 0, arranged in chamber M, located at the top of the cylinder, and having ports N, all constructed and arranged as shown and described, to operate as specified.
2. The curved rocking valve O, in combination with the ports N of working chambers G G, said valve working in a horizontal seat, as shown and described, for the purpose specifled.
' WILLIAM V. DUBOIS.
