Description
UNITED STnTEs PATEETAQEIIIGE- IMPROVEMENT lN 'CHAIN-PUMPS.
Specification forming part of Letters Patent No. 127,576, dated June 4, 1872.
construction and arrangement of a bucket for a chain-pump, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- A Figure l is a plan view, Fig. 2 a side view, and Fig. 3 a longitudinal section, of my chainpump bucket. Fig. is a plan view, and Fig.
V5 a longitudinal vertical section, of the same, showing the means for tightening or expand ing the same when reduced by Wear'.
A represents a wheel made of any suitable material, and provided with a deep circumferential groove, a', leaving a flange, b, on either side. In the groove a, between the flanges b b, is placed a thick rubber collar, B, projecting a suitable distance beyond the flanges, as
shown. Through the center of the wheel A is,
passed a wire, C, forming hooks or eyes at each end to connect with the adjoining buckets on both sides. d represents the vent, usually made through the buckets of chainpumps. These vents are very liable to become stopped up, and to obvia-te this difculty I make a notch, e, in the edge of the rubber collar B to answer fora vent, which can readily be cleared if it should become clogged.
When the collar or band B wears so that it does not fill the tube, it can be removed and a piece, f, of leather or other material inserted to increase the size of the rubber, and thus ll the tube as good as new.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. The wheel A, having groove a, anges b b, and wire C, and provided in the groove a with the rubber collar B, having vent or notch e, substantially as herein set forth.
2. YIn combination With the above, the leather or other material f, inserted in the groove a, substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 8th day of March, l1872.
WILLIAM COOPER.
