' specication. t v x 5 i This invention relates to' means for turning the power of moving bodies of water to prac- Vtical Suse by mechanical means, in which a .current-rotated part is the prime or initial element inthe train of elements wherebyl thev zo' transmission of the power is effected. Many vmechanisms of this sort have been proposed patented; but I am not aware that any z5; o power comparatively inexpensively really Warrants. Some of the reasons-for this 'ap pear to be the following: Theprevious appae ratuses were vinthe rst place not so designed vas-,that the various :controlling conditions 3o would permittheir being constructed' on aA scale large enough to accomplish any material economy over-other methods of develop-` i,ingpo'wen If'the second place, the Werenot constructed with a view to norma y prothoroughly withstand theeflects of ice,`logs`, and other bodies calculated to damage their mechanism. Again, in these previous a'ppaf the general contribution to the power transmission, .with the consequence that if any one became disordered ory inoperative the whole mechanism was' crippled and must be 45stoped.

assumed by bodies of ice, logs, or other debris from the space beneath said gratings, being the spaces of the several ilumes. The upstream end of each flume is formed with an incline Z, which merges at its upper end with the natural river-bed and at its lower end with the bottom of the fiume. These portions of the flumes may be covered by other gratings m, substantially like the gratings i.

In the iumes under each grating is arranged a current-driven element a. Each of these is shown as two screws o, arranged in tandem on a common'shaft p.

g r/aretwo standards in which the shaft p is journaled, the downstreamv end of said shaft having a socketed bearing s, in which .and a socket t in the standard fr is arranged a 'ball u. The bodies v of the two screws are preferably cylindrical and air-tight, so that buoyancy is impaited to the screws and the friction en the bearings in standards q and i" reduced.

On the shaft p between the ltwo screws of each current-driven element is fixed a bevelv gear Iw, which meshes with a bevel-gear on a vertical shaft y. The several vertical shafts y extend down through the linings g of the lumes and theilling of cement underneath the same and project into a tubular shaft-tunnel z, disposed transversely of the watercourse. This tunnel may consist of a steel tube 1, provided with an inside lining 2 (say of brick) In this tunnel z are supports 4 I for a shaft 5, which is connected wrth each transverse series of shafts y by bevel-gearing 6. 7 designates power-transmitting means connecting shaft 5 with a dynamo 8 or other power-distributing medium located above ground, as in the power-house 9. (Shown in the drawings.) The means 7 extends through a concrete wall 10. In order to drain the tunnel, which is inclined from its middle toward both ends, as best shown in Fig. 1, of water nding its way into the same, a drainpipe 11 may be provided.

Should it be necessary in orderto make repairs or for other reasons to cut off the supply of water from any one or more of the current-driven elements, gates 12 may be forced down through slots 1&- in the plates c vand inI guides 14 in the iiumes. To this end a cofferam 15 may iirst be lowered into the stream and allowed to rest on the artificial bed around the grating for the current-driven element to be eut off, whereupon the gates" may be closed and thwater then'pumped out of the cofer-dam and the portionof the flume thus isolated, leaving the latter clear,

,so that the Irepairs can be accomplished.-

16 is a platform extending parallel with the watercourse, on which is a car 17, which may be used to convey the coffer-dam and itsA ssories from one transverse series of curre tf'driven elements to another.

1,8 is cable having its .ends attached to and set in a cylindrical body of runners 19, running on guideways 20, the said cable being extended over other runners 21, running on guideways 22. Only one set of these runners and guideways-is shown in the drawings.

23 represents auxiliary supports for the cable 18, arranged opposite each transverse series of gratings. These auxiliar supports are only employed when the cab e has been shifted along its guideways 20 and 22 to the proper position, being then needed to sustain the weight of the coder-dam when it is swung out over the stream.

25 is' an inclined well which communicates `with the channel z and is adapted for introducing the shafting 5 to said tunnel. Both this and the well 10 may be formed of contitioned off, as at 27, to form a series of airchambers or breatliin -spaces foi" the workmen should the tunne be flooded while they are at work therein.

' In order to permit the rotation of any one of the current-driven elements to be stopped,

Fig. 2 as a ratchet 28, fixed on shaft, land a springo-pressed pawl 29, pivoted on the meniber of-the gearing which is carried by said shaft.

By depressing the artificial bed slightly below the natural bed, as at e, a downward inipulse is Given to the water at this point, so that the 1force of the current is brought in as elements as on the remainder.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with a watercourse structure having longitudinal and transverse spaces, of a rotary device adapted to be oper ated by the flowing body of water in said structure and located in the longitudinal space, power-transmitting means operatively connected to said device and having a p ortion thereof traversing said structure and located in said transverse space and below the horizontal plane of said device, and means for supporting said .rotary device and the power-transmitting means, substantially as described.
