SPECIFICATION forming part of Letters Patent No. 224,862, dated February 24, 1880.

' Application filed December 18, 1879.

.To all whom (may concern: i

,Be it known that I, GEORGEy E. BIGELOW,

i et Geneva, in the county ofFillmore and State ofNebraska, have invented a new and Improved Water Elevator, of which the following is a specification.

` Figurel is a side elevation of the device partly in section. Fig. 2 is a transverse section of the same on line ao x, Fig. l.4

.'This invention relates to that class of devices that are designed for raising water from Wells;

The invention consists of a conical' axle car rying a chain or rope to one end oi' which a Weightis fastened, said axle supporting, also, a wheel or pulley Which carries a chain or rope, one end ot' which is attached to the `Wheel and the other end to a bucket.

In the drawings, A represents the upright framework; B, the conical axle, revolving in suitable bearings and carrying the rope O, ,one end ofwhich is fastened to the axle B and the other to the Weight D. E is the Wheel or pulley keyed to the axle B, said Wheel carryinga chain or rope, F, one end of which is fastened to the said wheel and the other end to the bucket G. His a she-ave journaled in the jhangers I at the top of the frame-Work A, and over this sheave H runs -the rope or chain C. K represents the Well from Which the Water is to be drawn.

Assuming that for a sixty-foot Well the `bucket will Weigh tive pounds,and the rope five pounds, and the Water lilling thebucket twenty pounds, makin gta total of thirty pounds to be raised from the Water-line' to the top of the well, and assuming that the wheel E is thirty inches in diameter and the axle B :seven and one-half inches in diameter, or onequarter of the diameter of the Wheel E where the rope C begins to Wind on it, it will be seen that one pound suspended from the Wheel E will balance four pounds on the axle B; hence it will require one hundred and twenty pounds on the axle B to balance thirty pounds., or the l Weight of rope and bucket full of Water.,on the Wheel E; but as the rope F unwinds from the Wheel E as the bucket G descends in to the Well 5o K there is an increased pull exerted on the said Wheel E, and as the said bucket is raised from the Water more power must be exerted than when it (the bucket) is part Way up, for all the rope attached to the 'said bucket has to be 5 5 raised. ln order, then,to equalize the draft I make the axle B tapering or conical.

The axle being seven and a half inches in diameter where'the rope begins to Wind on it,

one hundred and twenty pounds weight will 6o be required to be suspended from it, as before stated, to balance thirtypounds on the Wheel; but by making the said axle increase in diameter to ten inches, or one-third as large as the Wheel Where the rope ceases to wind on the 65 said axle, ninety pounds weight suspended from this p oint will balance thirty suspended from the Wheel. Thus by using the conical axle B in combination With the Wheel E, I increase the value of a eounterbalance of con 7o stant Weightwhen drawing the bucket from the' Well, and also save time and labor in the operation, because fewer turns of theaxle Will be required to Wind the rope F up.

Having thus described In y'invention, I claim 7 as new and desire to secure by Letters Patentl l. In a water-elevator, a conical axle carrying a rope and counter balance-weight, in combination With a Wheel carrying a rope and 8o bucket, substantially as and for the purpose described.`

2. The conical axle B, rope G, Weight D, sheave H, and frame A, in combination With the Wheel rope F, and bucket G, arranged 85
