UNITED STATES PATENT OFFICE.`
IMPROVEMENT IN WATER-ELEVATORS.
Specification forming part of Letters Patent No. 38,068, dated March 31, 1863.
T0 all whom it may concern:
Be it known that 1,1). E. TEAL, ofNorwich, in the county of Ghenango and State of New York, have invented a new and useful Improvement in Windlasses for Wells; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is an end view of my invention. Fig. 2 is a plan or top view of the same. Fig. 3 is a section of the same, taken in the line a', Fig. 2. Fig. 4 is an inverted plan of the chief parts of Fig. 2.
Similar letters of reference indicate correspoudin g parts in the several figures.
This invention relates to an improvement in windlasses for wells, for which Letters Patent were granted to me, bearing date November 27, 1860.
The object ofthe within-described invention is to obtain the same result as by the old but by a simple means, and one less liable to get out of repair, more economical to manufacture, and capable of being manipulated with greater facility. Y.
To enable those skilled in the art to fully understand and construct my invention, I will will proceed to describe it.
A represents the shaft of a windlass, said shaft being tted in suitable bearings on a wellcurb. B is a drum, which is permanently secured on the shaftA, and C is a ratchet, which is secured to the shaft A at the outer side of its bearings and adjoining a crank D, whiehis placed loosely on shaft A, but is retained thereon by a nut, E. (Shown in Figs. 1 and 2.) The crank D at its inner end extends some distance beyond the shaft A, and is connected by a pin, a, to an ellipse, F, which encompasses a circular ange, b, which flange is at the outer side and concentric with the ratchet C. The ellipse Fhas a lug or projection, c, which engages with the ratchet G, and
forms a connection between the crank and tI e' ratchet and windlass, so that by turning the crank D in the proper direction the windlass will be turned and the bucket elevated, the rope or chain of the latter being wound up on the drum B, as usual.
E is a holding-pawl, which is attached to the weltcurb or its framing. This pawl enwill catch into the ratchet C and cause the drum B to rotate, so that the well-bucket will be elevated.
In order to release the windlass from the crank D, the latter is turned backward or in areverse direction until the projection c strikes the pawl E, when the latter will be thrown out of gear with the ratchet. When the projcetion c is in contact with the pawl E, and the crank D still moved or forced back, the ellipse F serves as a brake and bears against the lower part ofthe flange b, and by pressing more or less hard on the crank D the descent oi' the bucket may be regulated as desired. The oval form of F admits of a certain requisite degree of play of F on the iiange b after the projection c has thrown out the pawl E. This is essential in order to admit of a free retrograde movement of the windlass when necessary.
The advantage of this arrangement is that as soon as the pawl E is disengaged from the ratchet C the brake may be almost instantly applied when necessary, no interval being al lowed for the bucket to descend and get under headway.
The parts it will be seen are few and simple and involve no arrangement liable to get out of repair or become deranged by use. By this arrangement no spring is required, as in my previously-patented device, and the lever is also dispensed with. The withindescribed invention, therefore, is not only more simple than the patented device, but also less liable to get out of repair. Springs, as is well known, soon become deranged and inoperative when exposed to moisture, and the employment of the lever against which the spring of my patented device acts, involves the necessity of certain manipulation on the part of the operator,which is avoided by my present or withindeseribed improvement. These advantages, in connection with the instantaneous or quick application of the brake on the reversing of the movement of the crank, render, it is bel lieved, the invention much superior to the pata ented device previously referred to.
I do not claim any of the parts when sepation aand attached to the crank D,the oval F, rately considered; but, encompassing the flange b, and all arranged Having thus described my invention, what substantially as and for the purpose set forth. I do claim as new, and desire to secure by Letters Patent, is
The combination vof the ratchet C and flange Za, paWl E', ellipse F, provided with the projec- DANIEL E. TEAL. Witnesses:
