987,685. I i a 4 specificationofnemrslimm, PatentedMar. 28 19111,- Application filed May 16', 1910. Serial No. 5611 53.

To all whom it may concern:

I heat 5, which is sd constructed as "ieadny l float upon the Water andw'ithinsaidzbeat is placed a train of'gears 6, which gears; are adapted to operate any preferred plece of v60 Be ithnowi'r that I, Uinals'ro'r'r-inii C. a 'r- KINSON, a cltlzen of the- "United States, re-

siding at l-Imvk1ns\-'11le, 1n the eounty of:

Pulaski ant indiez'ites a chored onIthe-hed of a body 0t Water and 2 l State of Georgia, have invented -rrerta1n new and useful 'In'iprovements in Tide or Wave Ooerated Motors' and I do I 1 hereby declare'the follhwing to be a, full, clear,:and exact description of the invention, such-as will enable others skilled in the art to which' it appertains to make and use the same.

' My invention relates tonew and useful i1i-l 1 1-ov'en1ents in tide or Wave operated n1otors and my object is to provide means for anchoring" a boat in position to he raised and lowered by the action of the tide or waves. v I

A. further ObJBCt is to provide means for v employing the raising and lowering of the boat toropera-t-ing a dynamo or other object through a train of gears, and, a-turther oh gect 1s to 'pro'vlde means .tra1n ofgears when the boat is. g ther. as-

cending or descending.

Other olo'ects and advantages vvill be hereinafter referred to and more particularly pointedout in the specifieation' and claims.

In the accompanying drawin 's which arm made a part of this appliet 'il'OXl, Figure 1 is :1 side elevation of, the brim in its anchored position. ig. is a top; plan viewot the boat showing the anchoringmeans in section. Fig. 3 is an enlarged detail sectional view as seen on line 3-3 Fig. 1. Fig. 4 is a detail. elevation of the parts shown in Fie'. 3. his. 5 is a detail sectional view otone of the shafts with the gear therefor removod, said section being; shown on line 5--5 Fig. and, Fin: Bis an end elevation of the gear (soopernting wit-h th* shaft shown in Fig. Referring to the drawings in which similar refer-make numerals designate Corresponding: q arts throughout the several views, 1

base, which is preferably animlicatcs standards extending u wardlv from said base and spaced a predetermined distance apart, said standardsheing held rigidly .invertical. position hvprovidingstay rods 2;, with-h are provided "in their length buckles 4, and are etlvmlrd' from. theuppcr ends of the standards with adjusting turn ilmrlgiv'ai'dly and outwardly edge oil'he base.. v

Positionedbetween the standards L to the outer is a shafts 11 which pro for. operating the machinery, such as a dynamo' i' or the-alike. Extending along op )os1teedges of the standards 2 are cogs- 18 and 19. said-cogs being mounted upon shafts 1 0 and llQrespectivcly, said shaftsextending; through '65 suitable hearings-12 and 13 in the Wallsfo'f the boat. The shaft extendsentirety through the boat, while there are two ot the ect but a short distance within the baht, the shaft 10 havinga gear 1-1 thereon, which cooperates with thc'train of gears 6. The shafts '11 are attached to .the shaft 10 by placing on said shafts sprocket gears 15 and 16 respectlvely',lwith which cooperates sprocket chainsl'i and-by. 7 5 means of which power is applied to the shaft .tO. whenthe shafts lit are'operatedp The boat is held in position hetweeirthe standards Qhyextending; the ends otth's "shafts beyond the outer Wall of the hea and rotatahly mounting thereon-said cogs -18'and 19 respectively, said cogs being vpro-' vided at their ends with disks 20 an .=21,

which disks are greater'in diameter thai, the

diameter of the cogs vand grqeet on opposit faces of the standards 2"a11d as t'he peripheries of: thegcogs engage. the opposite edges of the standards, the' boat will be securelyheld in position-beturen the stai'idardsflvhile at the same time said heat will bGPBI'IllIl-t-t-Gd 9 to rise and fall with the tide or W'itli' the action of thew-eves. .l r

The shafts '10 and 11 are operated by the cogs 1.8 and 19 by placing series of teeth .22

and 2-3 on the opposite edges of the stand-. ards, the series of teeth 22 being at a point sl'ibstant-ially' midway between the apperand lower endsof the standards, While the series of teeth 23 on the opposite edge thereof are adjacent the upper ends of the standards, the two series of teeth overlapping each other for a distance. The cogs 18 and .19 are loosely mounted upon their respectire shafts and are provided with circular cavities 2 1-. on their inner extend ratvhe'ts 2:) fixed to the shafts 10 and 11, and eoiiperating with the teeth or the 'ratehetsare pawls 20, whichv are held n engagement with the ratchets in anysuitable manner, as by means of springs 27'. 'l-he ratchcts and pawls-in the cogs 19 are rz-n'iged" to rotate the shafts 11 when-theb'oat ends, in which '9 the shaft 10 and the is ascending, while the ratchets and pawls in the cogs 18 are arranged to operate the shaft 10 when the boat is descending. As the shafts ll are connected to the shaft 10 by means of the sprocket chains and gears, the pawls andratchets in the different cogs are so arranged that when one.set of cogs are rotating their respective shaft or shafts, the opposite cogs will run idle upon their bearings and vice versa when the opposite set of cogs are in operation.

' In operation, supposing the body of water to be at low tide,.the boat will be positioned, as shown'in Fig. 1, and as the tide starts to rise, the boat will move npwardly until the cogs l9 engage the series of teeth 23, when the shafts 11 will be driven by saidi cogs andthe driving motion imparted to the shaft 10 by the chained?v and the sprocket gears with which the chains 00- operate. This action will operate the train of. gears within the boat and the dynamo or other object to which the train of gears is hitched and it will be readily seen that by properlyarranging the train of gears, the speed of the dynamo orother object can be readily increased or decreased. Should waves be running on the water, the boat will be raised and lowered by said waves,

thereby keeping the train of gears in constantoperationl As the tide recedes, the boat will descend with the tide and move the cogs 18 into engagement with. the teeth 22, when motion will be imparted direct to train of gears con- 'nected therewith.

This device can be very cheaply constructedand readily applied to use and it will be seen that the machinery Within the boat will be positively driven and contwo. subscribing witnesses.

trolled by the action of the water-upon- Which the boat is resting.

What 'I claim is 1. In a power generating device, the comshafts projecting on opposite edges of the standards, cogs mounted on said shafts, means to cause said cogs to rotate the shafts when moved in one direction and means to operatively connect, said shafts together.

2. In a power generating mechanism, the combination with a'boat adapted to rise and fall with the body of water upon which the boat'is resting, said boat having gears therein, of standards on opposite sides of the boat, said standards having series of teeth on their edges, shafts connected to said gears and projecting from the boat, cogs rotatable on said shafts and adapted to engage the teeth on the standards, sprockets on said shafts,'chains connecting said sprockets and means to cause certain of'the cogs to impart motion to their respective shafts when moved in one direction and run idle when moved in the opposite direction.

In testimony whereof I have slgned my name to this specification inthe presence of CHRISTOPHER o. ATKINSON.
