ALBERT LEGG, OF ALLENDALE, NEW JERSEY.

HYDRAULIC ENGINE.

SPECIFICATION forming' part of Letters Patent No. 716,254, dated December 16, 1902,

` i i. Application filed January 18,1901. Serial No. 43,711. (No model.)

To all whom it nung/concern Beit knownthat I, ALBERT LEGG, a citizen of the United States of America, residing in the town of Allendale, county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Water or HydranlicEngines, of which the followingis a specification, reference being had therein to the accompanying drawings.

My invention relates to water or hydraulic engines; and its objects are to provide a simple and inexpensive `means of developing power from a moving column of water and to render such means readily adjustable to eX- isting systems of water-supply.

To these ends my invention consists of a box or chamber adapted to receive and hold the water from a moving column thereof, two hollow cylinders communicating with said chamber and the atmosphere, devices connected with said cylinders upon which the Water supplied to the chamber may operate, and means of transmitting the 'power devel` oped by said devices vto a revolvingshaft.

An application ofA my device is illustrated in the accompanying drawings, in which similar figures of reference indicate similar parts throughout the various views, of whichi Figure 1 is a sectional View on the line l l of Fig. 2. Fig. 2 is a side elevation, partly broken away. Fig. 3 is an enlarged detail view, and Fig. 4 is a sectional view on line 4 4 of Fig. 3.

1 is a pipe leading into chamberl2, the pipe and chamber being constructed of sufficient strength to withstand the pressure under which the Water is received by pipe 1.

3 and 4 are two hollow" cylinders, each firmly secured to the chamber 2 and at one end communicating with-the interior thereof and at the other end with the atmosphere. The communication of cylinder 3 with the atmosphere is shown in the drawings by dis-iV rod 1l;

14 is a cover sufficient to cut off communi- Operatively con-A 'is loosely mounted on rod, l1, so that when said cover 14 is forced toward the end of cylinder 3 it will abut against abutment 13 and carry with it rod 11 on crank 9.

15 is a lug on rod 11 to retain cover 14 in position when chamber 2 has no water therein under pressure. Abutment 13 should be adjusted so that cover 14 will close the end of cylinder 3 shortly before rod 11 has comp leted its stroke in that direction.

Figs. 3 and 4 illustrate a good method of constructing the inner end of cylinder 3.

18 is a shoulder or seat for cover 14, and 19 19 are slides cooperating with grooves on cover 14.

Operatively connected with., crank l0 is jointed rod 12, bearing at4 its other endgpiston 16, working in cylinder 4. c

17 is a wheel upon shaft 8, .operating to balance the device. If the wheel is turned so that cover 14 has opened communication between chamber 2 and cylinder 3 and water underpressure is allowed to enter chamber 2, whenthe same becomes full, or nearly so, the force of the water will push said cover so as to close cylinder 3, and wheel17 will continue to revolve so long as water is allowed to enter chamber 2 under pressure, the water escaping through discharge-pipe 5. When the pressure of the'water has caused cover 14 to close cylinder 3, thus preventing .the outflow of water at that point, the pressure, apparently in the nature of a blow, is delivered against the bottom of piston 16, forcing said piston 16 up'in cylinder4,"carry ing with it rod 12, which being operatively connected with crank 10` causes the shaft 8 and carrying-wheel 17 to revolve. This upward movement causes cover 14 to descend, thus releasing water through Vent 5. At this point the water-pressure is considerably reduced, so that but little resistance is offered to the descent of'piston 16 to a position in which the operation is repeated. j

P ipe 1 may be provided with a`valve 20 without departingfrom myinvention." 2l is a check for said valve.

What I claim, and desire to secureby Letters Patent, is-

1. A water or hydraulic engine consisting of a chamber adapted to receive and hold wa- ICO rer under pressure, two cylinders each communicating with said chamber and with the atmosphere, a piston adapted to operate in one of said cylinders, a cover adapted to close the inner end of the other of said cylinders, a revolving shaft having two cranks thereon, means'whereby as said piston is operated one of said cranks is operated, and whereby as said cover is operated, to close communication between said chamber and one of said cylinders the other of said cranks is operated, and means of maintaining a supply of water in said chamber under pressure, substantially as described.

2. In a water or hydraulic engine, the combination ofa chamber adapted to receive and hold Water under pressure, two cylinders each communicating with said chamber and with the atmosphere, a piston adapted to operate in one of said cylinders, a cover adapted to close the inner end of the other of said cylinders, a revolving shaft-having two cranks thereon, means whereby, as said piston is operated, one of said cranks is operated, and whereby as said cover is operated to close communication between said chamber and one of said cylinders, the other of said cranks is operated; and means of maintaining a supply of water in said chamber under pressure, with a valve adapted to cut off the supply of water when the pressure in the chamber is greater than the pressure of said water-supply, substantially as described.

3. In a water or hydraulic engine, the combination of achamber adapted to receive and hold water under pressure, two cylinders each communicating with said chamber and with the atmosphere, a piston adapted to operate in one of said cylinders, a cover adapted to close the inner end of the other of said cylinders, a revolving shaft having two cranks thereon, means whereby, as said piston isoperated, one of said cranks is operated,'and whereby as said cover is operated to close communication between said chamber and one of said cylinders, the other of said cranks is operated; and means of maintaining a supply of water in said chamber under pressure, with a balance-wheel mounted on said shaft, substantially as described.

4. In a water or hydraulic engine, the combination of a chamber adapted to receive and hold water under pressure, two cylinders each communicating with said chamber and with the atmosphere, a piston adapted to opcrate in one of said cylinders, a cover adapted to close the inner end of the other of said cylinders, a revolving shaft having two cranks thereon, means whereby, as said piston is operated, one of said cranks is operated, and whereby as said cover is operated to close communication between said chamber and one of said cylinders, the other of said cranks is operated; and means of maintaining a supply of water in said chamber under pressure, with a valve adapted to cut o the supply of water when the pressure in the chamber is greater than the pressure of said water-supply, and a balance wheel mounted on said shaft, substantially as described.

In witness whereof I hereunto affix my name, in presence of two witnesses, this 17th day of January, 1901.

ALBERT LEGG.
