IMPROVEMENT IN CHAIN-PUMP BUCKETS.

Specification forming part of Letters Patent No. 175,697, dated April 4, 1876; application iled February 3, 1876.

Z'o all whom it may concern:

Be it known that I, S. (l. HAMLIN, of Ypsilanti, in the county of Washtenaw and State ot' Michigan, have invented certain new and usel'ul Improvements in Chain-Pump Buckets 5 and I do hereby declare that the following is a full, clear., and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form part of this specification.

My invention relates to buckets for chainpumps; and it consists in a chain-pump bucket composed of a series of rubber disks, with flat bearin g-ed ges placed upon a central link also, in the construction ot' the link, and in the combination of parts, 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- Figure l is a plan view of my chain-pump bucket. Fig. 2 is a side view, and Fig. 3 a vertical section, of the same. Figs. 4 and 5 are sections of the link.

The central link of my bucket is composed of a cylindrical body, A, with a flange, Band eye C at one end, and an eye, D, at the other end, which latter eye forms two projections, d d, as shown more fully in Fig. 5.J On this link are placed a series of rubber disks, G G, having at bearing-edges, as shown, said disks being supported upon the head or flange B below, and held by the projections d on top from being drawn o" when the bucket is run l backward. The body A of the link is lluted or grooved longitudinally, as shown at c, to allow the water to pass down to the source of supply. These grooves may be two or more in number, and pass through the flange B at the bottom, making its sides fan-shaped, and

as said openings are in the metal they will not be filled up by compressing the rubber, as is the case with holes through the rubber.

This bucket will Work either side up, or either way in thetube, and thus allow of being turned backward to carry the water back to the source of supply. The tluted lilik allows the water to pass down as the Water depresses the bucket or makes it concave, turning the water to the center when at rest. The rub` bers, being sliced, makes them much more elastic, and brings a broader bearing-surface against the tube, and will, consequently, wear much longer and Work much easier than those now generally in use.

In case ot' Wear the disks or slices G lnay be simply changed in position, thus renewing the bucket without expense.

The rubber disks may be expanded by simply placing open or half collars around the link-body A. rlhe rubber is to be sliced either in the edge or entirely through, and ot' suitable thickness to allow any number on the link.

Having thus fully described m'y invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A chain-pump bucket composed of a series ot` rubber disks or slices having llat bearing-edges, 'and placed on a centr'al link, for the purposes herein set forth.

2. The combination of the grooved link A with liange B, eyes O D, and projections d, and the sliced rubber G, placed thereon, and having tlat bearing-ed ges, substantially as and for the purposes herein set forth.

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

, SOLOMON O. HAMLIN.
