JOSIAH HAYDEE OF HAYDENVILLE, MASSACHUSETTS.

IMPROVEMNT IN WATEFl-ELEVATORSIl Specification forming part of Letters Patent No. 36,300, dated August 26, 1862.

To all whom t may concern:

Be it known that I, J osIAH HAYDEN, of Haydenville, in the county of Hampshire and State of Massachusetts, have invented new and useful Improvements in Vater-Drawers; and I do hereby declare that the following is a full and complete description of the construction and operation of the saine, reference being had to the accompanying drawings, making part of this speccation, in which- Figure 1 is a perspective view. Fig 2 is a vertical section; and Figs. 3, 4, and 5 are detached parts.

The nature of my invention relates, irst, to the form and structure of the chain; second, to the windlass-wheel, and, third, to the form and operation of the pall and ratchet.

C represents'the curb. This is made in the usual form. The shaft S is secured to the top of the curb by boxes B. The windlass-wheel W is secured to the shaft S at the middle. The circumference of the wheel is divided into angular teeth T, the outer ends of which are in the form of a flattened wedge or wedgeshaped cone, the base of the teeth uniting together on a line about an inch within the circumference of the point, the length of the base being equal to about twice the height of the teeth.

R represents a ratchet-wheel placed on the crank end of the shaft S, the teeth of which point toward the front side or dischargespout A.

P is a pawl which is pivoted to the curb at P', from which point extends a short lever, P, the end of which extends over the edge of the curb and admits of a depression only so far as to raise the pawl P from the teeth of the ratchettwheel R. 'The pawl P being longer than the lever P, its superior gravity will always keep it in contact with the ratchet-wheel teeth, and, consequently, when the bucket is ascending it is always secure from running back should the hand of the operator slip from the crank-handle. Serious injuries and son1etimes loss of life have arisen from accidents of this kind by the crank striking the operator. In letting the bucket into the well the lever P is pressed down upon the top of the curb, and the ratchet is thus relieved from contact with the pawl.

G represents the chain. This is constructed in a peculiar formand especially adapted to of the chain G, so far as is necessary to a clear description of its structure. The openings in the links of this chain are made to correspond in size with the base of the teeth T. Each link is formed of one piece of wire, bent into a peculiar form and embracing with their free ends the middle portion of the wire that forms the next link. The sides a of the link are straight. The ends are formed into a hook, as seen at b. At o the rod is bent outward and then inward and slightly forward between the bars a, forming the curve c d o. The free and hooked ends b of another link are firmly clasped around the depression c, and the forward curve, d, prevents the free ends I) from approaching each other when the chain is put upon la tension, and by means of the outward curve, c, the sides of the links, (seen at (0,) are brought nearly into line with each other, and, consequently, the chain will sustain a greater weight Without becoming elongated by strain than it would if the body of the links were curved.

A chain constructed in the manner above described possesses certain properties not found in any other chain. The curves c d c form a series of arches that give a certain degree of elasticity to the chain, preventing the links from breaking on being subjected to any sudden strain, while at the same time the absolute strength of the chain is not in the least impaired. The curve d acts especially in this manner, for if the hooks b I) passed around a straight bar extending from c to c the tendency would be, in applying tension to the chain, to curve the link in a direction opposite to that shown at d in Fig. 4; but in this case the tendencyis rather to increase than diminish the curvature of the arch d, and hence the integrity of the structure.

The length of the links is such that the base of the teeth on the windlasswheel will fill them, and, consequently, there can be no slip of the chain in drawing water.

The bucket is formed with a valve, V, in the bottom, through which the water enters in filling. The bail B of the bucket is hinged` just above the middle, as seen in section in Fig. 2, and to the front side of the bucket is attached a rod, D, which passes within the horizontal rod E, which is hinged to the curb and swings up over the inner end of the spout A. By this means the bucket is changed from its natural position while ascending to the horizontal position indicated by the red lines in Fig. 2, and thus the water is discharged i into the spout. i

The bucket is balanced by a weight, F, l

which hangs upon the opposite end of the chain G to balance the Weight of the bucket.
