WILLIAM ADAIR, OF LIVERPOOL, ENGLAND.
IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent No. 1 82,737, dated October 3, 1876; application filed March 14, 1876.
valve of small weight and for increasing the durability of valves used in ships pumps and in pumps for mines, or where grit or other substances is or are liable to pass the said valves with the liquid raised.
I employ a flexible disk-valve of india-rubher or leather and a perforated free featherlift or like valve combined together as one. The said flexible disk-valve, when the pump is in action, opens and closes quickly, so as to serve to allow the liquid and grit, sand, or like substance to pass freely in an upward direction, but prevents return of the said liquid. The liquid, in rising, passes the said flexible disk-valve instead of flowing between the feather-lift valve and its seat, as heretofore. Hence all abrasion and wear of the said liftvalve and seat are avoided. If, however, any.
The accompanying sheet of drawings illustrates this part of my invention. This view shows a double-action ships pump fitted with my improved valve, part of the sides of one of valve-chambers being removed for this purpose- The lower valve shows my improvement, in which the india-rubber-disk valve on works on the perforated seat b and-seating c, and is guided in its lift by the feathers d.
Under ordinary working the valve or only operates, the valve b working only in case of emergency. The upper valve shows the same improvement in a skeleton-frame, in which the india-rubber disk at fits on its perforated seating 12 and seat 0, and is guided in its lift by the spindle e, which works loosely in the guide f, preferably made with three prongs or legs, 9, to rest on the recess or annular platform h.
It will be obvious that either of the above compound valves can be at once removed-as a whole from its place.
I do not claim, broadly, the use of compound valves; but
I claim 1. The compound pump-valve described, consisting of a flexible disk, a, perforated i valve 1), and feathers d, the disk a being capable of opening independently of as well as with the valve 12, substantially as set forth.
2. The flexible disk at and perforated valve 12, in combination with the frame e f g of the dischargechamber of a pumping apparatus, substantially as set forth.
