IMPROVEMENT IN' WATER-ELEVATORS.

The Schedule referredA to in these Letters Patent and making part of the same To all whom it may concern Be it known vthatI, BERNHARD VATEE, of the city of NewYork,iu the `county and I; State of New York, have invented a. new and improved iVater-Eleratou andl do hereby declare that'the following is a full, clear, and exact description thercof,^whichlwill enable Yothers'sltilled inthe art-to makeaud use the same, reference heiugjfllad tothe accompanying drawing forming part of this specification.

Figure 1 represents a side elevation, partly in section, of my improved water-elevator.

Figure 2 is a'trausverse section through the spiral wheel. u Similar letters of reference indicatecorrespomling parts.

rlC-he invention consists-in' so constructing the spirai wheel 'that the convolutions of the same shall graduall y or successively diminish iuwidth or capacity for containing air and water, from the'cent-ral shaft ou'tward.

The object of this peculiar construction is to adapt the. wheel toelevate a gi'eater'quantity of water, sincet'hecuhical capacity of each separate convolution is tobe equal to everyother.

vA in the drawing represents aspira-l wheel, mounted upon a tubular axle, B, which-has its bearings in suitable fiume, C.

The wheel Bis made to constitute one continuous spiral channel, a., .hy being provided with a continuous partition', l), as shown in iig. 2..

The-drawing represents a whe-el with twelve convolutions. This number can he increased or diminished at pleasure. The convolutions become broader toward the center of lthe wheel, as indicated lin iig. 1, sol

that those of lesser diameter will bc -able to contain the same amount of liquid as the others.

One end of the axle B is closed. vThe other end communicates with the dischargepipe D, which may be placed vertically, horizontally, or iuany other suitable posit-ion.

The outer end'of the channel a" is open, and constitutes a bucket for taking up the water or other liquid. Rotzu-ymotion, in thc direction of thcarrows, iig. 2,

is then imparted to the axle and wheel by suitable mechanism. l The wheel is to about two-thirds .of its height immersed in thcliqnid which is to be conveyed. As it is revolved, t-he wheel will gradually convey the liquid toward its'center, but in each convolution 4oi' the spiral,'theliquid will sta-ud ouiy'proportionately atthe same height to which the wheel is immersed. l lhere will, consequently, be an air-spaceleft in thev upper partl oi' each convolution, as is clearly shown in fig,.- 2, and eachconvolution,owing to the difference in Width, will contain as much water and air as each of the others. i l y As thc wneelfis being revolved, its open end will,

during two-thirds of each revolution, take up .liquid 'andforcc it int-o the channel, expelling thereby au equal amount from the centralcouvolution in theuaxle and discharge-pipe.. lheremaining one-third revolu-l tion causes asimilar displacement-of air. The col# umn of liquid in the discharge-pipe alone will,`\vith its-weight, tend to counteract'the action of the wheel,

while the liquidv within .the wheel, bearing with its weight toward the center, will exert aconstantpres'sure in the direction in which the liquid is to beconandin planes parallel to said shaft, substantially as herein shown and described, and' for the purpose speciiied.
