Tl DE-WATER ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 241,937, dated May 24, 1881.

Application tiled June 25, 1880. (No model.)

.To all whom it may concern:

Beit known that I, ROBERT GREUZBAUR, of the city of Brooklyn, E. D., in the county ot' Kings and State of New York, have invented 5 a new and useful combination of mechanism for raisin g waterby the force ot' the tide, named the Tide-Water Elevator,7 which is fully described in the following specification, reference being had to the accompanying drawings.

The principal object of my invention is to raise water on and neartide-watereoasts,bays, inlets, and rivers, to be applied to cleansing house-closets and drains, to the liushing ot' sewers, for sprinkling streets, and for manufacturingandotherpurposes. Iaccomplishthe Object by causing the hood-tide to store water in a reservoir, this stored water beingy prevented from returning with the ebb-tide by a self-closin g valve. When a sufficient head or difference ot' level is established between the stored water and the ebbtide a channel is opened, which admits the stored water to a hydraulic ram or other water-elevatin g mechanism, which delivers the water where desired.

5 In the accompanying drawings, Figure l is a sectional elevation of my tide-water elevator, and Fig. 2 is a sectional elevation of a modifi' cation of a portion of the saine.

InFig. 1, A is a pipe or drain through which the tide-water flows into the large reservoir B, the pressure ci' theincomin g water forcing open the valve O,which may be made so as to be very little heavier than water, being made hollow, or loaded with cork, or made of light material, so that the Water in the reservoir B will attain nearly as high a level as the tide. When the tide recedes the valve C closes and prevents the escape ot' the water from the tank B.

D is a large pipe or a small tank, in which the tide rises and falls freely through the branch pipe d', connecting with pipe A. This pipe or tank D may be inside of the reservoir B, as shown, or it may be outside and separate from it. In this pipe D a lioat, F, operates, attached to rod E, which rod is attached to centrally-pivoted lever G, the other end of lever G being attached to valve H, which controls the entrance into drive-pipe'l, which feeds the hydraulic ram R. Therwater raised by the ram Rpa'sses through the pipe K to its destination. The loat F may be vertically adjusta- I ble upon rod E by nuts?? a.

Fig. l shows the ram Rinoperative, the valve H being closed by the ioat Fthrough its tendency to rise with the water entering tank D. During ebbAtide the valve O remains closed, and as soon as the tide has suliiciently receded the weight of tloatF, when no longer sustained by the water, overcomes the weight of valve H with its attachments, as well as the pressure ot' the water upon the saine. Assoon as valve H is partly open the water-pressure upon the same is sutticiently balanced to cause the iioat F to descend suddenly andsufcien tl y to throw valve H wide open, thus setting the ram into instant-operation. The float F need not be a body or vessel lighter than water and able to float upon the Sallie, but may be simply a dis placer of water, as a piece of wood, iron, or of any other substance, a correspondingdisplacer, G', being attached to the outlet-valve H of such relative weight that when both bodies F and G' are submerged the valve H, with its displacer G and attachments, will be heavy enough to seat. When the water has receded from displacer or float F, leaving it dry, a weight equal to the body of water displaced by F and its attach ments will be acting in overcoming the overweight of valve H and its displacer Gl and attachments, as well as the pressure ot' the water upon the valve H. For instance, the valve having an area ot' twenty square inches and the depth of Water upon it being twenty-eight inches, the water displaced by iioatordisplacer F must be over twenty pounds, added to the weight necessary to overcome theoverweight of valveH and its attachments.

The reservoir B is best made large enough, so that its water-level will not fall very much during the operation of the ram in order to prolong its operation under a good head.

Instead ot' the float F and lever G, or of two displacers, G and F, and roekbeam G, with their attachments, the arrangement shown in Fig. 2 may be used.

The small tankD adjoins the res'ervoirB, with a ilat partition, d2, between the two, into which a flexible diaphragm, M, is inserted at a proper height, and centrally pivoted by rod m' to the upright arm h' of valve H. While the water stands equally high in tanks B andD, this diaphragm M stands centrally and the valve H is closed. When the water has receded sufficiently from tank D to uncover the diaphragm IOC more or less on that side, the pressure of the water in reservoir B will force the diaphragm into the position shown, thus opening valve ll. As thepressure ot' the water upon valve H before its opening will give a greater resistance than when through its opening that pressureis no longer unbalanced, the diaphragm M, upon the opening ofthe valve H, will suddenlvv move farther in toward tank I), thus throwing valve H wide open. When the diaphragm M becomes suiciently uncovered on the reservoir B side also, the diaphragm returns to its central po. sition, aided by the weight of valve il.

The inlet into pipe l should be protected by a large strainer, N, Fig. 1, to prevent the entrance of obstructions into the ram.

The float F, insteadof being in apipeortank, D, may be anywhere in unobstructed tide-water.

The details can be varied according to eircumstanees and in man",v ways.

I do not claim in an artilicial spring or bulk head an underground drain combined with a hydraulic ram and a drive-pipe which receives water from a reservoir suitably located in the drain, the waste water ol" the ram and ot' the reservoir heilig discharged into a continuation of the drain which extends past the ram; but

Vilhat I claim as my invention is- 1. The combination, with a reservoir and a valve or gate through which it is supplied with water by dood-tide, but which is closed during ebb-tide, of a hydraulic rain and drive-pipe adapted to receive water from said reservoir and to deliver it in eleva-ted positions, substantially as herein described.

L. The combination, with a reservoir and a valve or gate through which itis supplied with water by iloodtide, but which is closed during ebbtide, ol' a hydraulic ram adapted to deliver water at elevated positions, a drive-pipe for ieeding said rain from said reservoir, and a valve which admits water from said reservoir to said pipe, and which is automatically controlled and periodically closed and opened by mechanism operated by the rising and falling of' the tide, substantially as herein described.

3. The combination ot'storage-basin B with inlet A, valve C, valve H, auxiliary tank D, displaeers G and F, rock-beam Gr, channel l, and water-raising mechanism R, with their con` nections and appurtenances, operating conjointly substantialb` as described.
