Water Elevator.

UNITED STATES PATENT OEEICE.

GEORGE B. CURTIS, OF WOLOOTT, N. Y., ASSIGNOR TO P. K. BRONSON.

IMPROVEM ENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. 58,019, dated September l1, 1866.

To all whom 'it may concern:

Be it known that I, GEORGE B. CURTIS, of Wolcott, in the county of Wayne and State of New York, have invented a new and useful Improvement in Water-Elevators 5 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a front elevation of the windlass and its appurtenances, theplate a of the hanger-jaw J being broken away to show the V- shaped head h of the locking-bolt. Fig. 2 is a transverse section taken in the direction of the red line o in Fig. l.

Similar letters indicate like parts.

This invention belongs to that class of water-elevators in which two self-dumpin g buckets are employed; and its nature consists in s0 constructing and arranging the tilting or shifting lever as to avoid the use of any auxiliary lever; and also in substituting a spiral spring for the strap-spring heretofore used for securing the proper adjustment of the parts.

To enable others to make and use my invention I will describe it more fully.

A represents the top ofthe curb-frame; B, the cross-bar, to which the hanger-jaw J is bolted. I use the double spools S, intermediate gear G, and feathered clutch O, ordinarily employed in this class of water-elevators but I extend the arms E of the tilting lever D, as shown in Fig. 1, so that the dumping-buckets shall strike them directly, instead of using two sets of arms, as heretofore done. vrlhe fork of the lever at b is spread so as to permit that portion of the lever to swing past the center before operating upon the clutch O, whereby the center of the traverse-pulley o is carried past the point of the V-shaped head h of the spring-bolt I, and hence the change of the sliding coupling or clutch is effected by the spring s, and that instantaneously. The lever D is pivoted to the hanger-jaw J at e, and the pulley o is pivoted to the lever below its axis. The square opening through the stock or jaw J for head of the spring-bolt I to work in may be cored out, and the hole in the foot-plate f, for the lower end of the bolt, may also be cored, if desired, or it may be drilled.

One end of the spring s rests against the head h of the bolt I, and the other upon the plate f.

It will be seen that this construction and arrangement of 'the parts constitute a much simpler and cheaper device, and also a much more durable one than those in common use for the same purpose.

Vhat I claim as my invention, anddesire to secure by Letters Patent, is

l. The arrangement, in double-bucket water-elevators, substantially as shown, of the single tilting lever D and its spring-bolt I, in combination with the sliding clutch O, for the purposes set forth. i 2. The spiral spring s and its locking-bolt I, in combination with the tilting bar D, substantially as and for the purpose herein shown and described.
