UNITED sTArr s PATENT OFFICE.

NOAH S. EDENS, OF HIGHLAND, CALIFORNIA.

WAVE AND TIDE MOTOR.

To all whom it may concern:

Be it known that I, NOAH S. EoENs, a citizen of the United States, residing at Highland, in the county of San Bernardino and State of California, have invented new and useful Improvements in Wave and Tide Motors, of which the following is a specification.

This invention relates to motors of that type in which the varying level and undu-' lations of a body of water are utilized to produce mechanical power, and the present invention is more especially an improvement on the motor dlsclosed in my prior application for Letters Patent of the United States, Serial No. 481,263, and filed March 5th, 1909. The invention has for one of its obje ts to to manufacture, reliable and efficient in use and of, durable and substantial design.

Another object of the invention is the em- 'ployment of a rotary spiral, which-is 'rotated by separate ratchet mechanisms which utilize the variations of the tide and the lateral im pact of waves, so that continuous rotary movement can be obtained, by such motions in a body of water.

With these objects in view, and others as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accom anying drawings, which show one embodiment of the invention; Figure 1 is afcentral vertical section of the apparatus. Fig. 2 is a vertical section on line 2-2of-'F1g. 1. Fig. 3,is a sectional view of the ratchet mechanism for operating the spiral shaft by the lateral movement of the float. Fig. 4 1s a sectional view on line 4--4: of Fig. 3'. Fig. '5 is a perspective View of the connection lock for mounting a pawl carrying lever on its support.

Specification of Letters Patent.

Application filed September 7, 1910.

Patented June 13, 1911.

Serial No. 580,848.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referrin to the drawing, A designates a pier, Whar or other support on which the motor is mounted. The frame of the motor consists of standards 1, secured at the lower ends to a base 2, and at the upper ends to a plate 3, and at an intermediate point on the standards is a horizontal bracing ring-- structure of the motor rises and secured coupling head 6, and under the head is a spider bearing 8 in which is held a ball or enlargement 9 to support the float in such a, manner that it can sway in any direction like a pendulum. The splder or base frame 7, to

gether with the coupling element .6 forms a cross head, designated generally by C, and the spider is provided with bearing sleeves 9' which slide on the guide rods 4. The

that is provided with a socket coupling element 6 is capable of changing,

its position with respect to the spider as the float sways but is held normally in par.- allelism with the spider by a plurality of extension springs 10 connected with the outer ends of the spider arms and with the under side of the coupling element or head 6, the s rings cooperatintr with th of the oat to assist in eiiec't-i'ng the return movement of the latter. j I

Mounted above the couplingelements ti is a verticall disposed rotary and longitudinal movab e shaft '11, which is intended to rotate by the lateral or pendulum movement of the float and to move longitudinally by the rise'and fall of the float, the movement -of the shaft being utilized in any suitable manner for performing work. The lower "end "of the shaft is mounted in a frame which consists of a cross bar, spider or the like 12, which is connected by posts 13 with a plate 14 and on this plate 14 is a step bearing 15 for the lower end of the shaft 11, the spider 12 being provided with a bearing 16 for an intermediate portion of the shaft}: This frame is connected with the spider 7 by tie rods 137 so" that the cross head C is ri idly connected with the frame consisting of forms therewith a cross-head structure adapted to reciprocate in themain frame of-the machine the upper portion of the cross head structure being guided on the rods 4: by sleeves 18. v

Secured on the lower portion of the shaft :11 are upper and lower ratchet wheels 19 and 20 that are disposed adacent. the parts 12' and 14, respectively, with hearing bzrlls 21. interposed between the ratchet wheels and seidtpar s. Each ratchet wheel has 11 wardly ecing ratchet teeth 23 and the ratchet teeth of both Wheels slant in the some. direction, and co-a'cting with these ratchet wheels are a pluralit of pairs of pawls. 24: and 25 the pawl's o each. pair hemg ivoted to the extremities, of the arms 6'0 a -shaped lever 27. In the present instance, six of these levers are shown and hence six.- sets or twelve. pawl's engage the ratchet wheels. The levers are m unted on a spider 28 secured to the posts 13 and as shown. .ig- 4;... the levers, together with the pawlsare disposed in tangential relati n' to the ratchet wheels Each lever is fnlcrumedin the recess 29 of the connectin block 3, Figs 4 and 5, which block has rooves 31v at opposite sides so as to fit in t .e slot 32' of the'arm of the s idler or so port- 28.. The outer ends, of t e levers 7 are provided with coupling devices 33 for connection with the u for ends of. combined pushand pull rods the. 1 wer ends, of which are. connected with the coupling head 6, as clearly shown inFi 1., the join-ts be tween the extremities of t e connecting rods $41 and; cou'pli devices 33: and head" 6 being of the, hel and socket type. By this ratchet mechanism, the lateral movement of the float will cause rotary movement of the shaft 11,, which rotary movement ill. be continuous in the same direction as long as the pendulum action of the. float continues.

hen the float swings to the. right, Fig. 1., theeoupling head 6"; wmalltilt ins'uch a direction as to. push. upwardly the levers 27 at one s de: of the: ratchctfmechanismand pull dlametrically cpposite .ewl's down so that the varts will e. in he; position as shown in ig. 3 and this movement, the u per pawls of the levers at one'side and: t elower paw'l's of thezlevers at the. opposite side w 'l tary impulse on the-"shaft I1, and as the levers tilt in the opposite direction by the rethe parts 12-, 13 and 14 and so that when the sh pinions 49 meshing I positivelyienga ge their re spective ratchet w eels. and. produce a. ro-

turn swing of the float, the other formerly of some driven part, the upper portion of the shaft is provided with a pair of crossed 1 spiral, or right and left helical grooves 35 and 36 and at. the top plate 3 of the supporting frame are separate ratchet whee s 87 and 38, through the hubs of which the shaft extends. Each wheel is provided with an internal rib or feather 39 for eng'a ing in one of the spiral moves of the sha .11,

at moves u. flwardly, one wheel will turn therewith, anrfas it moves downwardly, the other wheel will be turned. Between the ratchet wheels 3? and 38 is a gear wheel 40, and the inner opposite faces of the wheel are provided with ratchet teeth 41 and- 42, respectively, with which codperate spring-pressed pawls 43 and 44: carried by the gear wheel 40; th pams 43 being arranged in a plagie at right angles t the lane i which the pawls 44 are disposed. he ratchet wheel 37 held in place by a yoke or cross bar 45 secured to post 46011 the top plate 3 while the ratchet Wh l 38 is set into a bearing plate or disk. 4? on. the

plate 3, there being ball bearings arranged between the relatively movable parts of h ratchet mechanism which converts the 10 1'- gitudinal movements of the shaft I1 into rotary movement. of the gear 40; The gear 40. drives one or more shafts 48 which have with the gear; and power can be taken from the shafts 4.8 in any suitable manner for performing useful work, the shafts being supported Inboari'ngs 50' on the top of th main frame. The gear 4.0 may be driven either by the vertical .mOVEIII DIl of the shaft 11 as when the water is comparatively smooth but is changing with the tide, or it. can be driven by the. r tary movement of the shaft. 11 incident to the. pendulum action of the float, caused by the waves or roughness of the water, or the gear may be rotated by the combined rotary and longitudinal movement of the shaft 11 due to the simultaneous actions f the waves and tide on the, float.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and of the method of operationwill be. readily apparent to those. skilled in the art to which he invention relates-and; while I have described the'principle of operation of the invention, together with the device which I now consider to be the best embodiment shaft, separate r thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as are within the scope of the claims.
