These channels are preferably constructed of concrete, and are covered but are open toward the sea or other body of Water. Be-

tween these channels there is an enclosed float chamber 3, of the. nature of a coffer I dam whose side walls are common" with the ad acent side walls of thefchannelsl, 1, and" whose ends meet concrete and formed to completely exclude .the ater;';' Near the ground surface the chamber 3 li asanoutlet open ng 4 whichina'y be opened and closed by a gate Valve 5 operable through the rod 6, which carries a hand wheel 7,on top. of the, chamber, through which the valve may beoperated. l

In the channels, and float chamber there are the floats, 8, Band 10, respectively. Each float 8 has ;a transverse rotatablyinounted shaft as 11,. whoseendhas a pinion 12- fixed thereon and in mesh w'itha-si' nilar pinion 13 mounted to rotate on said float 8. There-is avertical shaft 14 whose upperend has a bearing in the bracket'15 fastened to the of the corresponding channel 1, The lower end of this shaft hasabearing in the pier 16 beneath the channel and carries a turbine wheel 17 whichislocated in the inlet end of .the water conduit 18 which leads out through said pier 19, beneath the chamber 3, and continues'up through said pier and on up through-the floatlO and is then turned downwardly into adischarge chamber 20, in said float 1Q, 'andlis controlled by a gate ,.valve 21. Theconduit 18'is formed with a thereof taken on the line 1111 of Fig suitable slip. joint 22, supported onthe pier 19. Located in the outlet chamber 20 there tively, are the piers 28,29. The upper end of-the pier 28 has the inlet end of a water conduit 30 leading downwardly therethrough and outwardly turned, and which enters and leads up through the 'pier 29-and on up through thecorresponding float 8 and is a turbine 34 located therein which is fixed 'on the lower end of a vertical shaft 35.

The float 10 supports a transverse rotatable shaft 7 37, similar to the shaft 27, and fixed on one end thereof there is a pinion 38 in mesh with a similar pinion 39, carried by the float 10 and splined on the shaft 35. In the outlet chamber 31 there is a turbine which is 41. The upper end of this shaft has a fixed fixed on the lower end of the vertical shaft pinion 42 which'is in mesh with a similar pinion 43, which is fixed on the adjacent end of a transverse shaft 44, all carried by the 2 "corresponding float 8.

The gate valve 21 may be opened to admit I water, through the conduit 18 into the chamher 3 and the inflowing current will rotate theturbines 17 and 23 and, in turn, will drive the shafts 11 and 27. Upon ebb of the tide the valve 21 being closed the valve 33 may be 0 ened and the water in the chamber 3 will ow out through the conduit 30, rotating the turbines 34'and 40 as it escapes. From these turbines the shafts 37 and 44 are driven." The shafts 11,27, 37 and '44 are power delivery shafts and may be utilized to drive electric generators, or any other mechanism desired, located on the corresponding floats.

mechanism, carried by them, and which will nowbe described, a description of the mechof one float being sufiicient for all, since they are similar in essential particularsfl 'Referring to Figures 1 and 3, the float 10 is shown-With four pair of end sheaves,

and 46, 46'. 'Near the respective ends of the float are the airs of large sheaves rotatable in horizontal planes, the sheaves of each pair being concentric and indicated by the these pairs of sheaves there are two counter which are the adjacent spools 50, 51, with pairs of guide pulleys 52 arranged on opposite sides, as shown in Figure '3.

A number of cables are provided, each cable beinga-ttached at one end to one of the piers 2 and at its other end to the topof the corresponding channel 1. One of these cables is indicated by the numeral 53. It passes up over the corresponding end sheave 45, and around the top sheaves 47 and 48, being wound around the corresponding intermediate spool 50, and working on the guide pulleys 52, and it passes then around under the opposite pulley 46. As the float moves in one direction this cable will rotate the spool 50 and theshaft 49 on which the spool is fixed. Another cable 54 is attached, at its upper end, as explained, and it passes around under the sheave 45' and around the upper pulleys 47, 48, being wound around the intermediate spool 51 and held thereon by the guide pulleys 52. This cable passes thence around over the pulley 46 and its other end is attached to the corresponding pier 2, beneath, and as the float rises the cable 54 assists in driving the upper shaft 49. V

Ina similar manner'the cables 55- and 56, operate over the sheaves 45, 46 and 45, 46,

respectively, and around the lower sheaves 47 and 48 the lower spools 50, 51, to drive the lower counter shaft 49.

The float 10, whichis taken as an illustration, and Which, in the particulars here inafter stated, is similar to the other floats, has a transverse partition 58, forming a plat form, or flooring, for the support of operative mechanism, and also forming one or more ballast chambers 10 beneath it.

In Figure 3 a section of the top of this float is broken away, revealing reduction ascending gearing 59, eniployed,.and which includes a jack shaft 60, which is driven from the shafts 49, through sprocket wheels,

61, 61 fixed on the shafts 49, and driving Ill) through the chains 62, 62, which operate 70, 70. Around the respective pulleys 70 are i the cables '71, 71 which are coiled around the drums 72, 72 and are confined thereon by the guide pulleys 73, 73. The drums 72 are fixed on the power shafts 74, 74 each of which carries also the fixed sprockets 75,

76. It is obvious that as the float 10 rises th rotation of the mechanism liereinbefore described, including the shafts 74, will be in a direction the reverseof its movement when the float falls. In other words the shafts 74 will rock backand forth. It is necessary to convert this rocking movement lnto the sprockets 75, 76, and driven thereby are the respective sprocket chains 77, 78. The chains 77 operate over, and drive, the sprockets 79, loosely mounted on the respective shafts 80, 80. The inner ends of' the hubs of the sprockets 79 are formed into clutch jaws 81, 81. The chains 78, 78 have outside drive connections with sprockets 82, 82, which are loosely mounted on the shafts 80, and said chains are mamtamed 1n mesh with said sprockets 82 by means of the idlers 83,, 83 over which the chains 78 operate.

' The inner ends of the hubs of the sprockets 82 are formed into clutch jaws 84, 84.

Splined on the shafts 80, between the clutch members 81 and 84 there are the clutch "members 85,185, whoserespective ends are also-formed with jaws adapted to engage the respective jaws 81 and 84 when said 5 last named jaws are driven forwardly, but

to be'disengaged, when said clutch jaws are re'versely driven.

When the shaft 74 is driven in one direction it will drive its corresponding sprocket 79- in a direction to cause the clutch jaw 81 to maintain driving engagement with the clutchmern-ber 85 and the shaft 80 will be correspondingly rotated. Meanwhile the sprocket 82 will idly rotatereversely with respect tothe rotation of sprocket 79. Now

upon reverse rotation of shaft 74 the clutch member 85 will be automatically disengaged from the clutch jaw 81 and carried into engagement with the clutch jaw 84, which upon reversal of the shaft 74 has also reversed, as to its rotation, and now continues 'to drive the shaft 80 in its original direction. Beneath the shaft80 are the spaced brackets 87 and 88 and the clutch lever 89 is pivotally mounted between them. The upper end of this lever is formed into a yoke 90, which engages in the annular groove 91 of the clutch member 85. Fastened to the inside of the bracket 88 there is a lock plate 92, which is provided with vertical slots 93 to receive the securing bolts 94 on which the pu is vertically adjustable. The upper end of this plate is formed with a lug 95,

fora purpose to be hereinafter stated.

There is a shift plate96, pivoted to the lower :end of the clutch lever 89. This plate has lon transverse bearing 97 in which a sheave 98 runs and a weight 99 is suspended from this, sheave; The plate 96 i, rocks on its pivot connection with the lever 89 but the range of its movement is limited by thespaced stops 100, 100 arranged on opposite'sides of'the lever 89. The plate 92 I has the oppositely disposed, upwardly curved slots 101, 102 inwhich the inner'end of the pin 108, supporting the plate '96, is

lengthwise, on the shaft 80, toward the clutch jaw 84. The lug operating against the lug 104' has just swung the plate-96 into the position shown and the weight 99 will cause the lower end of the lever 89 to swing around, the pin 103 moving to the outer end of the slot 102, carrying the lug 104 past the lug 95 and forcing the plate '92 downwardly until the lug '95 thereof again engages behind 'the lug 104', carried by the upper edge of theplate 96, and as said lever 89 swings around as stated the 'clutclrmember 85 will be carried into engagement with the clutch jaw 84. 'lVhen the clutch jaw 84 is reversed the sloping face'105 thereof, operating against the corresponding face 106, of the member85, will disengage said jaws and force the member 85,-along on the shaft 80 toward the jaw 81'. This will operate to swing the lower end of the lever 89 in the opposite direction and the lug 104,

operating against the lug 95, as a fulcrum, will operate to swing the plate 96in the opposite direction to that shown in Figure 7, causing the weight to run to the other end of the bearing slot 97 and the weight will cause the'lower end of the lever 89 to swing over, carrying the lug 104 past the lug 95, and carrying the pin 103 along th'eslot 101 thus lowering the plate 92 and engaging.

enlarged fragmentary view of the reduction gearing employed. The shaft, as for example shaft 63, on which the sprockets are mounted'has a lengthwise oil channel 111, into which the lubricantis fed from thecup 112. The pairs of sprockets, as for example 113, 114 are spacedapart by the sleeve-like spacer 115. The members of each pair are formed on a common hub 122 within which there is a wedge-like soft metatpacking, formed in lengthwise sections-115, 115 and lined by the sectional hearing sleeve 116,

The hub 122- is formed, atone end, with radial slots 117, as shownin F ig. 9 and radial clamps 118 work in the slots 117, and abut against the large ends of the wedge sections 115. These clamps are formed with extended shanks 119 which work in lengthwise bearings in the hub 122, and whose -outer ends are threaded to receive the nuts 12.0, which are located in side recesses 121,

' ticularly adapted. for the type of device carried by thehub 122- Through these nuts, and the clamps 118 adjustable thereby, the

packing 115 may be adjusted, as desired.

This form of packing may be very quickly adjusted or replaced and is therefore parchambers, and the numeral 125 designates a reservoir which is elevated above said chambers. A suitable motor driven pump 126 is mounted on said reservoir and connected with the suction and discharge pipes 127,

128 'by means. of which water may be pumped, as needed, from the sluice way, or other water supply, 129 into said reservoir. Floats, as 10, are located in said chambers 1123 and 124.- These float chambers have valve controlled outlets 130, 131 into the sluice way 129, at their bottoms, and there is a valve controlled connecting conduit, or

, port 132, at the bottom of these chambers, through which water may pass from one to the other.

The reservoir 125 also has valve controlled outlet ports 133, 133 through which 7 Water may be admitted from the reservoir 'to the respective float chambers. The conduits and ports 130133 are controlled by conventional, hand operated gate valves, as 124.

-As shown in Figure 13 the chamber 123.

is full and the chamber 124 empty and the reservoir is also assumed to be full and the valves 134 all closed. The ort 132 is now opened and the water will rise in the chamber ,124 and fall in thechamber 123 to a common level, andsaid port 132 then closed.

The floats 10 respectively will rise and fall in a corresponding manner, and will operate the mechanism, hereinbcfore describe-d,

-which is mounted in said floats, but not shown in Figures 12-14. In this movement of the floats 10 both the buoyancy of one,

and gravity acting on the other will be utilized. The outlet 130 may now be opened to drain the chamber 123-and its float will further descend, generating power in its descent. The outlet 130 is then closed and the port 133, above the chamber 124 opened and; said chamber completely filled lifting the float 10, thereof to the top of the chamber, and the said port 133 is then closed. The port 132 may now be again opened to equalize the waterlevel in the float chambers and then closed and said floats will move, one up and the'other down, to a com mon level, each generating power, by such movements. The chamber 124 may be now drained, and the chamber 123 filled on up, as above explained, thus moving the floats 10 correspondingly, with a resultant gener drive the same.
