To all whom 'it may concern.-

Be it known that I, PETRUS SANDER, a citizen of Sweden, residing at Moline, in the county of Rock Island and State of Illinois, have yinvented certain new and useful Improvements in Apparatus for Actuating 11V ater-Wlotors, of which the following is a specification.

This invention relates to improvements in apparatus for actuating water motors and more particularly to that class of water motors designed for intermittent motion wherein the motive power is the rising tide of the sea.

Myapparatus consists of three floats each occupying a separate chamber. Two of the chambers are in communication with the sea at such a depth as to be nearly but not entirely submerged at high tide and ithe third is positioned entirely above the water line.

The object of the invention is to produce a device of this class that is cheap to manufacture and that is easy to construct.

With the foregoing and other objects in View the invention consists in the combination and arrangement of parts to be hereina-fter fully described in the following specification, pointed out in the claim and illustrated in the accompanying drawings which form a part of the specification and in which- Figure 1 is a `vertical sectional side elevation of the device. Fig. 2 is a plan.

Like reference characters indicate corresponding parts throughout the several views. I

1, 2 and 3 representthe chambers and 4, 5 and 6 the floats. structed without any side or end walls but with grooved rods for supports which sustain the roof 7 The float 4 disposed within this chamber is provided at its four corners with rollers Briding in the grooved rods or supports. Tot-he fioat 4 is secured a rack 9 which extends through the roof 7 and is partially supported by a guide 10 disposed upon,the roof and meshes with a serrated wheel 11 that is mounted upon a shaft 12 journaled in a pair of supports 13 also disposed upon the said roof. 14 is a sprocket wheel also carried by the shaft I12 and connected byy a chain 15 to another sprocket wheel 16 mounted upon a shaft 17 that is journaled in supports 18 upon the roof 19 of the chamber 2. This chamber is The chamber 1 is con-v walled and preferably formed of masonry or metal of some kind. The chamber 2 is further provided with an arm 20 which is hol-low and communicates with the interior .and projects out from the said chamber and has as a covering over its `free extremityr This chamber is further provided with a substantially cylindricall hollow water tight inner compartmentv 22 which snugly incases the float 5 and is provided lnear its lowervtermination with a water inlet valve 23 that communicates with the contents of the chamber 2 and at its upper extremity with an air pipe 24 and with an outlet pipe 25 near its base which pipe leads up through the chamber 2 and into thechamber 3 .and is provided with a check valve 26 toprevent the return of the water The oat 5 is Aprovided with a rack 27 that extends up through the roof 19 and through a guide 28, which is secured to the said roof, and engages a serrated, wheel 2S) mounted upon the shaft 17. I

Referring now to the chamber 3 which is disposed above the water level the same is provided with the float 6 and with an outlet pipe 30 vof much smaller diameter than the pipe 25 that furnishes water to the said chamber; the pipe 30 is provided with a turbine nozzle 31 above a water wheel 32 which is actuated by the water coming from the said nozzle and through thel medium of the water wheel 32 power may be conveyed or transmitted as desired by any preferred form of power transmission apparatus.

Operation: The chamber 1 is seated in shallow water at such a pointA that the high tide will not reach its roof; the chamber 2 is similarly seatetbbut the open end of its.

arm 20 is so positioned as to be below thel level of the water athigh tide. After the device Ais installed in position the first high tidey encountered by it will raise the float 4 but as the chamber 2 will be void of water no power will be generated, the first tide being used to fill the chamber 2 through the medium of its arm 20. After the tide has receded and the float 4 has been borne upon it to a vpoint nearest the base line of the chamber 1 the device will be in readiness for useful operation. The tide now again coming in will raise the float 4 which will raise the rack 9` and so rotate the shaft 12 transmitting power by the chain 15 to the shaft- 17 the connections of which will depress the rack 27 (the water level now being below the open end ot' arm 20) and float 5 will force the water in the compartment 22 out through the pipe 25 up into the chamber 3. Part of this Water Will escape with great force through the pipe and nozzle 31 upon the Water Wheel 82 While the excess Water Will lill the chamber 3 thus raising the float 6; when the tide has reached its greatest 'height the Water Within the compartment 22 Will have been forced out, the chamber' 2 will beginagain to fill with water coming in through the arm 20 and valve 23 thus raising the float 5 and rack QT, the air pipe 24 permitting the operation, and Whatever Water now remains in the chamber 3 Will soon be evacuated. With the receding tide the oat 4f. will again be carried to its lowest level,l during' which process the vpower is stopped, when it will be ready for the returning tide Which will cause a resumption of power.

What is claimed is -In a device of the class described, the combination with a pair of partially submerged Water chambers, of a third Water chamber disposed above the Water level, a float Within one of the partially submerged water chambers, an intermittently submerged arm open'at either end wconnected to the other partially submerged Water chamber, a compartment having an inletI valve disposed 'Within the last named partially submerged chamber, an air pipe connected to the said inner compartment projecting above the high Water level, a float within the said inner compartment, power transmission mechanism connecting thek last named float and the float beforementioned; an outlet pipe provided with a check valve connect-ing the said inner compartment and the aforel said third Water chamber, a float Wit-hin the last named chamber, an outlet pipe for that chamber and a Water wheel disposed beneath' the said outlet pipe.

In testimony that I claim the foregoing' as my own I have hereto aftixedmy signature inthe presence of two subscribing witnesses.
