lllhlllFl JOHN S. RAND, OF NORTH PROVIDENCE, RHODE ISLAND.

VATER-ELEVATOR.

To all 'whom it' may concern:

Be it known that l, JOHN S. RAND, of North Providence, in the county of Providence, in the State of Rhode lsland, have invented an improvement in l.Yell Buckets and rl`roughs for Drawing lfilater; and l do hereby declare that the following is a full, clear, and exact description of the construction and operation oit the same, reference being had to lthe annexed drawings, making part ot this specification, in which- Figure No. 1. is a side View of the apparatus with a part of the well curb removed, Fig. No. 2. a back view of the saine, Fig. No. 3. a perspective view of a portion of the apparatus for holding the bucket when raised. Fig. No. a. shows the bail oit the bucket with the rope passing through it.

Like letters refer to like parts in all the ligures.

V. is the well curb; z' the windlass; A, the bucket; L the counterbalance; m, an arm by which the shaft K bearing the latches H, l-l, is turned. my, the bucket rope passing through the bail D and fastened to the valve a. at the bottom of the bucket, F a slotted bar through which the rope a passes, C, C, bars or arms connecting the bar F to the trough B, P F F P shackle joints at the connections of the bars C with F and B J J, the fulcra of the trough B on which it turns as it rises or falls, O, O, guides in which the bars C O rest and move, l a trap door in the side of the curb opened by the end of the trough when it is raised.

lThe operation of my improved well bucket and trough is as follows: The bucket A is let down into the water in which it sinks by its own weight, the rope 5c is now allowed to slacken, when the valve a being ot metal or weighted wood, t'alls below the bucket and the water at once ills the bucket. This done the rope is drawn taut by the windlass. The valve a presses against the bottom of the bucket, closing the aperture, holding the water in the bucket until it is ready to be discharged as hereinafter described. When the bucket is sunk in the well, the trough B occupies the position a a (l. a. As the bucket is raised by the windlass, its bail soon strikes against the slotted bar F carrying it upward with it thereby raising the trough B through the actions of the arm C in a manner similar to that used in the mode described in the patent granted to John W. 1Wheeler dated January 17, 1860,

but more nearly like that described in my application for a patent which was rejected November third, A. D. 1860. As the slotted bar rises it strikes against the curvature ot' the latches Ll pressing them backward until the bar F slips over the catch of the latches,

where it rests, and holds the trough in its place. The chimes of the bucket now rest on a seatA prepared Within the trough. To discharge the water from the bucket the motion o1c the windlass is reversed, by which the valve a is permitted. to fall by its own weight and that of the water pressing upon it, and the water escapes into the trough. lf it is desired to retain a portion of the water, the hand is removed from the crank of the windlass after a portion of the water has escaped, and the weight of the counterbalance L draws the rope a: tight, closing the aperture in the bottom of the bucket by the valve a. lf the water is all discharged and the bucket is to be lowered the arm m is raised which throws back the latches so that their catches are at such an incline that the bar F will slip oil when the trough falls to the position a a a ce, and the bucket falls to a point within the well where its weight is counterbalanced by the weight L. The `arms O O now rest in the guides O. O. and the bar F remains in a position shown by Z). (Fig. ilo. 1) without pressing the rope x from its vertical position.

The advantages ot my improvement over other contrivances for drawing water, are these: The action of the valve a is automatic, moving from its own gravity, requiring no force to be applied as in the case in other contrivances having valves in the bottom ot' the bucket, it is not so easily put out oit order and will wear longer. The shaft l with its arm m and the latches H H is a great improvement, for holding the bucket in its place and keeping the trough from falling. The common accident of a bucket descending rapidly, causing the crank of the windlass to strike the operator is prevented by this arrangement. lt is of great value in saving the water in the bucket when it is not desired to use the bucket full at one time.

There is an advantage in the mode of attaching the bars C. by shackle joints to the bar F and the trough and in placing them in the guides formed and arranged as described. ln cold weather frost and ice collect on the inside ot the curb at various points, rendering many contrivances for raising water useless. Sometimes the arms C or their equivalents are so placed within the guides that their motion is vertical as in Vheelers patent. In my arrangement the arms C move curvilinearly as they rise and fall, causing these arms to act as levers on -the ice or frost, while their freedom of motion caused by the shackle joints facilitates their action and efectually clears away the ice and frost, removing every obstruction on the arms or within t-he guides.

The windlass with its crank, barrels and ropes or chains, and counterbalance L are,

old. It is no new contrivance to construct a trough and attach it to a slotted bar, and raise it by the bail of the bucket coming` in contact with the bar as described. A valve opening upward in a bucket is well known.

What l claim as my invention and desire 20 to secure by Letters Patent, is-

rlhe combination of the bucket A, constructed as described, with the arms C, trough B, bar F, latches H, shaft K and arm m, in the manner and for the purpose set 25
