TIDE PUMP.

Application filed November 24, 1923. Serial No. 676,795.

This invention relates to means for utilizing the tides to produce power for running various kinds of machinery, such as electric generators and the like.

Another object of the invention is to make the tide actuatepumps for forcing water to a high level where it can be made to run a turbine or the like.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter-fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a sectional view of one form of the invention.

Figure 2 is a sectional view of another form which shows the power producing apparatus carried by the pump apparatus itself.

Figure 3 is a modification of the form shown in Figure 2;?

Referring to Fig. 1 the piston 27 of the pump C is connected with a casing 28 which contains a weight 29. The casing is provided with a flange 30 which engages a shoulder 31 of the float 8" and a valve 32 is placed in the delivery pipe 33 of the pump. In this form of the invention water is drawn into the pump cylinder through the inletpipe 34 which is supplied with a check valve 35 when the parts are raised by the float and the valve 32 is kept closed so that when the float drops the casing with the weight will remain in raised position as the water in; the pump cylinder cannot escape. Then the valve 32 is opened, either by manual or other means, so that the weight in the casing will discharge the water from the pump cylinder with great force. This arrangement prevents the water from being gradually discharged as the weight slowly drops on the ebb tide.

In Figure 2 the housing 36=is carried by the pump cylinder 37 and said housing contains the turbines 38 and the generator 39. The turbines are connected by the pipes 40 with the discharge port 41 of the pump cylinder, a valve 42 being arranged in said nected with the base of the casing, these parts acting as means for preventing water reaching the pump parts. I The casing 36 is provided with the weights 54. The top of the casing is connected by the cable 55 with a. float 56 so that the raising of the float by the incoming tides will act to lift the casing on the pump cylinder and thus draw water into the pump cylinder through the passage 49. When the float drops the weight of the parts will cause the casing in the pump cylinder to move downwardly, thus forcing the water in the pump cylinder into the turbines to actuate the same and these in turn will operate the generator. The cables 45 and are of such relative lengths that the valve 42 will be closed before the float 56 reaches its highest point. The valve will remain closed until the float drops to a certain point when it will be opened by the lowering of the float 44 so that the weight of the parts will suddenly act upon the water in the pump, thus causing the same to be discharged under great pressure against the blades of the turbines.

In Figure 3 a pair of pumps E are shown which have their cylinders stationary instead of movable as in Figure 2. The pistons 57 of these cylinders are connected by the hollow piston rods 58 with the float 59 and pipes 60 connect the passages in the piston rods with the turbines 61, which, with the generator 62 are arranged in the float. A building 63 may be carried by the float in which an operator may live to take care of the apparatus. The passage in each piston rod is controlled by a valve 64 which is provided with a weighted arm 65 and this arm is connected by a cable 66 with a float 67 so that the valve will be closed before the float reaches its highest point, thus permitting the valve to be opened after the tide drops so as to place the water in the pump c'linders under pressure by the weight of t e' oat and permit it to be suddenly discharged into the turbines as soon as the tide drops to a point where the floats 67 will slacken the cables 66 to permit the valves to open.

From the foregoing it Will be seen that the tides are utilized to produce power and that the action is automatic and the parts require but little attention. The turbines shown in Figures 2 and 3 are provided With valve controlled outlets 38.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope ol the appended claims.

What I claim is V 1. An apparatus of the class described comprising a pump, a float actuated by the tides, means for operating the pump bythe movement of the float, means for holding the Water in the pump cylinder under presas sure While the tide is dropping and means for releasing the Water When the tide recedes farther.

2. An apparatus of the class described comprising a pump, a float actuated by the tides, means for operating the pump by the movement of the float, means for holding the Water in the pump cylinder under pressure While the float is dropping and automatic means for releasing the Water.

8. A device of the class described comprising a pump, a float actuated by the tides, means for connecting the float with a movable part of the pump, a valve in the pump passage and a second float, means for connecting said second float With the valve, the relative length of the connecting means between the main float and the movable part of the pump and the connecting means between the second float and the valve being such that the valve Will remain closed until the main float drops to a certain point so that the Water in the pump Will be placed under pressure before the valve is opened.

In testimony whereof I athX my signature.
