Description

Nmmaw N. PETERS. PHOTO LITHDGRAP WASHINGTON D C that@ 55u/tet AHOS A. MOULTON, OF PROVIDENCE, RHODE ISLAND.
Leners Patent No. 109.236. aateauovember 15, 1870.
IMPROVEMENT IN WATER-ELEl/ATORS.
The Schedule referred to in these Letters Patent and making part of the same.
To all .whom it may concern.-
Ee it known that I, AMos A. MOULTON, of Providence, county of Providence, and State 0f Rhode Island, have invented a new and improved Tater-Elevator, of which the following is a specification.
In the drawingf Figure l`is an eye symmetrical drawing.
Figure 2 is atop plan.
Figure 3 is a longitudinal central section.
Figure 4' is a sectional end view, showing the form of the lever and the manner of attaching it.
Similar letters represent like parts in the drawing.
My invention relates to an elevator for raising water, which consists of 'a shaft-operated by a crank, which has its fnlcrum upon a set of ratchet-teeth by means of a second similar set of teeth.
There is a lever attached to africtionwheel, to'
which wheel is also att-ached the iirst-mentioned set of ratchet-teeth. i
This lever throws the two sets of ratchet-teeth out of gear, and allows the bucket to descend into the well, and also in-combination with two friction-wheels acts as a brake to regulate the speed of the desc'cnt.
A dog inclines .laterally from the bearings of the shaft, so as to engage aratchetwheel, and prevents the crank from revolving backward when the bucket is beinglowered.
There is a drum attached to the main shaft in a con/- venient position for receiving the rope to which the bucket is attached.
This shaft revolves within an annular shaft, to which the crank is attached, by means of a slot and pin.
There are also two friction-wheels. The one to which the level' is attached has a lateral motion to correspond to that of the lever, but does not revolve, while the other is securely fastened upon the mainshaft, and revolves with it.
aIn the drawing- A represents the crank,whioh is attached 4.tothe annular shaft n by means of a slot and pin at an,
The main shaft R revolves within the annular shaft n.
The ratchet-wheel Gis firmly secured t`o .the annular shaft u, and, in' combination with -the dog s, prevents the crank A from revolving backward when the bucket is lowered.
The ratchet-teeth r project horizontally from the inner side of the ratchet-wheel O, and, in combination with similar teeth fr' on the circular piece a, turn the rlhe lever L has its fulcrum at the point g, and terminates in two curved arms, c and c', by which it is secured to the lips e and e" on the friction-wheel W.
The lever is held i'n position by a spring, spiral or otherwise, at the point y.
The operation of the apparatus is as follows:
In order to raise the water, the bucket is lowered into the well by throwing the lever into the position indicated by the dotted lines in iig. 2. Then, by increasing or diminishing the force applied to the handle of the lever, the speed of the descentmay be regulated or the bucket stopped at any point.
-By releasing the lever, it is forced into place by a spring, as c1, at the point g, and throws the projecting teeth on the ratchet and friction-wheels into gear. when by turning the crankv the bucket is raised.
I do not confine myself to the form of spring d, as a spiral spring can be used to equal advantage.
What I claim herein as new, and desire to secure by Letters Patent, is
1. The combination and arrangement of a lever, L, a spring at the point g, and the friction-wheels W and 2. The combination and `arrangement of the shaft R, friction-wheels W and W', annular piece a, ratchetteeth r and r', and annular shaft n.
3. The combination and arrangement of the friction-wheel W, annular piece a, ratchet-teeth fr', and
I ever L, all as shown, and operating substantially as described.
AMOS A. MOULTON.
