IMPRQVEMENT IN CHAIN-PUMP BUCKETS.

Specification forming part o f Letters Patent No. 163,013, dated May 117 1.875; application filed March 29, 1875.

To all whom it may concern:

Be it known that I, EDWIN Horfr, ot' Sta-n1- ford, in the county ot' Fairfield and State ot Connecticut, have invented certain new and useful Improvements in Buckets for Chain- Puinps 5 and do hereby declare that the following is affull, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specication.

My invention relates to improvements in chain-pumps, in which rubber buckets are employed; and it consists in the construction of the links, whereby the buckets may be more readily retained in their proper position, and in the construction and formation of the buckets.

In the drawings, Figure l is a plan view,

Fig. 2 a horizontal section, Fig. 3 avertical section, ot' one of my improved buckets 5 and Fig. 4 is a vertical section ot' a bucket applied to a link. -f

a is the bucket, made of indiarubber. It is formed with acentral hub, al, around which is formed a ange or rim, a2, having annular indentations a3 on the upper and under sides thereof, thereby giving the same form to both sides of the bucket, so that it is immaterial which side is placed uppermost in the pump. These annular indentations a3 increase the lifting capacity of the bucket, and, Without Wea-kening the latter, give a exibility to the rim or flan ge. In the periphery of the rim is formed a V- shaped recess, b. This recess admits air from an upper to a lower bucket, so that when the pumping is stopped the water in the pump will fall immediately to the bottom. It also admits of the compression and expansion-of the rim in the direction of the circumference, when necessary on account of any slight variation'ot' the size or" the tube in which it is used, and thus prevents an unequal Wearing away of the bucket. c is the link, constructed with the eyes c, at each end, for receiving connecting-links to form the chain. In the center ot' the link is formed a flange, e, which is adapted to be received within a recess, el, formed in the center of the hub al of the bucket. Recesses e2 are formed on opposite sides ofthe ange e, which are adapted to receive corresponding projections c3 formed on the interior ofthe recess e1, for the purpose of preventing the revolution or turning of the bucket on the link.

The link o having been formed as described and shown, the bucket .is formed thereon by suit-able molds, the material for the bucket being in a plastic form when first applied. By this means ot' construction the parts will tit closely and securely together.

The bucket, after being formed on the link, can be, it' desired, sprung ott' the link, and be again sprung on another.

It will be seen that my'improved buckets are reversible, so that when, by the action of their pressure exerted upon them, they become bent in one direction, they can be reversed and inverted. Y Having described my invention, what I claim, and desire to secure by Letters Patent,

1. An india-rubber bucket, a, constructed with a central hub, al, having the recessl el, and provided with projections c3, adapted to be received within recesses on a link, and a flange, a2, provided with a V-shaped recess, b, substantially as and for the purposes described.

2. A link, c, provided with eyes or loops c and a central iiange, e, formed with recesses e2 in its periphery, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

EDWIN HOYT.
