To etZZ wit/071a it may concern:

I Be it known that I, 'EDWA RD J RYAN, acitizen of the United States,residi'ng at Milltown, in the county of Washington and State of Maine, have invented certain new and useful Improvements in Wave Motors; and I'do hereby declare the follo Wing;to beafull, clear, and exact description of the invention ,s uch as will enable others skilled in the aftto'Which-it appertains to make and use the'sam'e.

and more especially that class of water-inotors known as tide-powers.

The object of my inventionis to provide a mechanism which will utilize the rise and fall of the waves to operate machinery In the present instance my preferred method of 0b tainin g this resu'ltis' to ap'plytlie force of said waves for the operation of air-p'umps'for'the storing of a large quantity'of compressed air in an air tank or reservoir. Said air is to be used for running compressed-air engines, which engines in their turn operate dynamos.

The advantages, operation, andconstrua tion of my invention will be described in the appended specification and pointed out in the claims, the accompanying drawings forming a part of this application, in whichwhen completed.

Mymotor is erected in the ocean afew miles off -the'- coast, where there is always a roll or ,swell-inthewater. It is built upon a stone or concrete foundation at thefbottorn ofthe ocean-and extends a suitable distance above the high water mark. .It is provided withsuit- .able sills and braces and sufficient ballast to Figure 1 is a side elevation showing the part above water of my invention asit will appear cause it to stand firm and secure in any storm. The methods employed for accomplishing this are such as are well known and commonly used by engineers doing this kind ot' work and for this reason are neither illustrated nor deand extends upward to the dynamo-room near the top of thetower. In the top of this tower is located the air tank or reservoir 2; The numeral 3 designates the outer tube, which. will hereinafter be referred to as the truck-tube. Said tube 3 encircles the cen; tral tube a short distance above the surface of the water.

is connected the hoop thy the journals and To the lower end of said tube bearings 5. On a line at right angles to that passing'through the journals 5 are the journals and bearings 6, which connect said hoop with the float 7, which rests upon the surface of the water, Fig. 2. Said float is substantially a hollow ring, its shape being like that of a pneumatic life-preserver. Located within the central tube, just above the surface of the water, is the lower sprocket-wheel 8, and just above and over the top of said tube is the upper sprocket-wheel 9. These two wheels carry the endless sprocket-chain 10.

It will be observed that the combined operation of the journals and bearings 5 with the journals and bearings 6 constitutes gimbals or joints admitting of a universal movement, which permits the float 7 to receive a wave and gracefully ride itfrom whatever direction it may come.

The dottedliue a a in Fig. 4: shows the water-line or surface of the water.

Located, preferably, in the upper end of the outer tube 3, on opposite sides of said tube, are the chain-grips 11 and 12, the former being adapted to grip the chain if said grip is carried upward and the latter of which likewise grips the chain when it (the grip) is moved downward. Said grips are further so constructed and related to each other that when the endless chain is gripped by either one and: caused to rotate the movement of' said chainwill not be resisted by the other, as will be hereinafter more fully explained.

When the float '7 is lifted by a wave, (being connected with the truck-tube 3, as already explained,) said tube will also be lifted, and as it goes up it of course carries its gripping devices upward with it. The upward grip 11 upon this upward movement of the truck-tube grasps the right side of the chain and carries it upward, which causes the top sprocket-wheel 9 to rotate. When the wave has passed, the float. falls downward again by gravity, .and as it fallsdown the grip 12 in like manner grips the. opposite side of the chain and draws it downward with it and causes said sprocketwheel to further rotate in the same direction, so that said wheel is kept rotating so long as the motion of the waves causes the float 7 and thle tube 3, connected therewith, to rise and fa l.

On either end of the shaft of the sprocketwheel 9 ismount-ed a crank, the two cranks being disposed at one hundred and eighty degrees to each other. Said cranks, by means ofthe connecting-rods 13,are adapted to operate the twin air-pumps 14, located on opposite sides of the air-tank 2, into which they pump air when they are in operation. This air is used to run compressed-air engines, which in their turn run dynamos, so that the force of the waves is ultimately converted into electricity. With the construction shown, Fig. 3, room 15 is deemed the most suitable place for locating the compressed-air engines. Room 16 likewise forms a suitable compartment for the location of dynamos, while room 17 may be used for living-compartments. From the dynamos in room 16, if desired,wires may run down the outside of airtank 2 and enter through suitable apertures the inside of the central tube and run down said tube to the bottom of the ocean and thence to any point on land to which it may be desired to convey the electricity. Storage batteries may also be provided, so that in very calm weather there will be stored up power for use. Suitable stairways or ladders (not shown) are provided to form a passageway from one room to another. Room 18 is intended fora light-house to be provided with brilliant electric lights from the dynamos within and on the top of said house is to be erected a powerful whistle to be operated when needed by air from the compressed-air tank. The lower compartments 10 are provided with the doors 20, which open to the. promenade 21 on the outside of the tower just above the cave of the roof. The upper room 16 islikewise surrounded with a smaller promenade. Said promenades are thoroughly provided with suitable railing and supported by suitable brackets, as shown. Compartment 19 is provided with a large central opening, through which truck-tube 3 may freely pass when the sea runs high, said opening, however, being surrounded with the railing 22. Opposite the top of said railing is the door 23, which forms a means of access to the insideof central tube 1. From said door a ladder may, it is obvious, extend down the inside of said tube to near the surface of the water. When itis desired to reach the lower sprocket-wheel for adjusting or oiling, this ladder (not shown) is used as a means of descent. On the outside of truck-tube 3 a ladder likewise extends from the top nearlyto the bottom. This ladderis reached by means of a suitable ladder (not shown) let down from railing 22. Hereby a means is provided for reaching the joints 5 and 6 when it is desired to oil or repair them and also the lower trucks, which are located immediately beneath the manholes 23. A suitable rail surrounds the tube a few feet from its bottom as a means of safety for the operator. The air-tank is provided with a pressure-gage and a safety-valve. (Not shown.) I further provide a safety-governor constructed on the'principle of the ordinary steam-engine governolgwhich operates to open a valve in a pipe connected with the air-tank and release a certain quantity of air when the pumps are acting with too great rapidity on account of ahigh sea.

The diflerent floors'are of course provided with suitable openings for the free passage of the endless chain, and the lower floor being of greater diameter than an y of the others and having a large opening in its central part for the passage of the truck-tube, which prevents it from being supported by the central tube, is supplied with necessary support ICC 627,533 j v a by means of the floor-hangers 24, which consist of iron or steel rods of suitable size, which rods depend from the floor above.

It will of course be understood that I will employ any desired material in the construction of the various parts of my invention; but it is thought that for the piles, braces, and tubes, and, in fact, nearly all the parts of my invention, steel will be the most suitable material to use, as it combines the maximum of strength with the greatest lightness and durability. Steel bolts will be very largely used in uniting the various parts together. This is especially true of the parts under Water. As will be seen from Figs. 1 and 2, that part of my water-tower between the cave of the roof and the water is surrounded by a netting made of very strong wire or small rods. This netting extends downward a few feet below the low-water mark, so that no driftwood or other foreign substance that may be afloat upon the water shall get entangled or come in contact with the operating mechanism of my water-motor. It will be found most expedient to have this netting made in frames constructed of thin strips of metal and of such shape and size as to fit snugly between the piles and braces, so that said frame may be secured to the outerflanges of said piles and braces by means of bolts. This, however, is simply mentioned as a matter of expediency, as I reserve the right to employ any method I may choose in connecting the wire-netting to my Water-tower.

Having now described the general construction and operation of my invention, I will proceed to more particularly describe certain details of the various parts.

The two shaft-bearings 25 are rigidly attached to the top of the float 7 at opposite sides thereof. Said bearings carry the journals 26, the inner ends of which are conical F in shape and work within the ball-bearing case 27, said case being rigidly attached to the hoop 4. Each of said ball-bearing cases 27 is provided with ball-bearin gs, as shown in Fig. 4, which reduces the friotion to a minimum at this point. The other pair of journals connecting the hoop with the truck-tube is also provided with ball-bearings. The hoop 4 may be made either solid or hollow, as the needs of the case may require; but it is thoughtthat ordinarily it will'best serve the purposes for which it is intended when made hollow and of material similar to that used in the float.

It will beobserved that the lower part of the truck-tube is provided with the base 28, which consists'of the vertical sides 29, somewhat larger in diameter than that of the truck-tube, the inwardly-inclined face 30, and the flange 31, which snugly receives the outside diameter of the truck-tube and is se curely riveted thereto. The upper pair of journals connecting the truck-tube with the hoopis attached to this base.

Figs. 6, 7, and 8 clearly illustrate the means greatlyreduced. I

tical purposes one set of trucks at the bottom employed to adjust the lower sprocket-wheel neck 36 of the adj listing-screw, the lower part of said bore being made of still larger diameter, having the offset 37, said larger diameter being adapted to receive the head or swell provided on the extreme lower end of the adj usting-screw. Since said cap is made in two sections, the two sections thereof are placed in their proper position around the collar 36 of the adjusting-screw and are then bolted together by the bolts 38, as clearly illustrated in Fig. 8. As will be further seen from Figs. 6 and 8, the bearing 32 is provided at its ends with the grooves 39, which receive the tongues of the blocks 40, as shown by dotted lines in Fig. 8, and said blocks are properly riveted to the tube at the edge of the opening-therein, as shown in Fig. 6, Where said bearings are located. The arched cross-bar 41, which rests upon the upper end of said blocks 40, is provided at its center with a threaded aperture, which receives the adjusting-screw,

and it is clearly apparent from Fig. 6 that said adjusting-screw, being attached to the bearing of journal 3, as already explained,

will when turned in onedirection raise said bearing and when turned in the opposite direction lower the same. The adj usting-screws are two in number, one on each side of the Y central tube to accommodate the two ends of the sprocket-shaft.

Fig. 12 illustrates my preferred means for reducing the friction in the upward-and-downward movement of trucktube 3 upon the central stationary tube. That part of the central tube which is traversed by the trucktube 3 is provided on its outer circumference with a suitable number of vertical rails 42, rigidly attached thereto. The tube 3 is provided on its innerside with a series of trucks 43, located a sufficient distance from each other along the entire length of said outer tube, said trucks being provided with flanges and adapted to cooperate with said rails, so

that when said tube is moved up and downby the force of the waves the friction caused by the horizontal travel of said waves is It is believedthat for pracand another at the top of said tube 3 will be sufficient for all ordinary requirements. I prefer to face the trucks with compressed fiber or other suitable material in order that their motion upon the rails may be as noiseless as possible. Fig. 13 illustrates the groove which I provide between the flanges of said trucks for the purpose of receiving this facing. Figs. 15 and 16 illustrate a means which may be employed for adjusting said trucks to their respective tracks. Fig. 15 shows a side elevation of one of the top and bottom trucks with this adjusting mechanism, while Fig. 16 shows a top plan view of the upper truck provided with this means of adjustment. The vertical braces 44 are securely riveted to the inner side of the truck-tube and are further secured in this position by the horizontal braces 45, said braces 44 being provided with the horizontal slots 46. WVithin said slots are located the bearing-blocks 47, in which are mounted the journals or axles of the trucks. Said bearing-blocks are made in two sections, as illustrated in Fig. 15, said sections being securely held together when in their operative position by bolts. The outer ends of said blocks are provided with recesses similar to those in blocks 35 of the adjusting arrangement for the lower sprocket-wheel. (See Fig. 7-.) This recess receives the inner end of the adj usting-bolt 48,which is provided with a'swell or head similar to that of the adjusting arrangement of the sprocket-wheel just referred to. It will be clearly seen that by the proper rotation of said bolts 48 the desired adjustment may be readily obtained. As will be seen from Fig. 16, each truck is provided with two of these adj Listing-screws, one for each end of its journal.

My chain-gripping devices, preferably located in the top of truck-tube 3, on opposite sides thereof, being rigidly secured thereto, as illustrated in Fig. 12, are two in number. The upward grip is illustrated in Fig. 10 and the downward grip in Figs. 9 and 11. The two grips are exactly alike in construction and principle, with this one difference: that in the one the ratchets and gravitydogs or pawls are so located with reference to each other that when the grip moves upward it carries the sprocket-chain with it, while the other grip carries the chain with it when it moves downward. Each of the grips is provided with the sprocket-shaft 49 and the roller-shaft 50. Each of said shafts is further provided with cog- wheels 51 and 52, rigidly attached thereto, which are of equal size and mesh with each other, causing said sprocket-wheel and roller to always move uniformly together, and in case one of the dogs or ratchets should be brokenthe other dog will through the mediation of the cog-wheels still cause the grip to reliably perform its work. Said shafts 49 and are further provided with the ratchets 53 and 54, which are also rigidly secured to said shafts. The rollers 55 are each provided with the apertures 56, adapted to receive the ends of the cogs of the sprocket-wheels 57, so that said sprocket-wheels may be located sufficiently close to their respective rollers to only allow the sprocket-chain to pass conveniently between them. By this means it will be impossible for the sprocket-chain to slip over the end of the cog with which it may happen to be in engagement at any time when a sudden jerk or strain is imposed upon it.

In the case of the upward grip, Fig. 10, it

will be observed that the ratchet-wheels and their gravity-dogs 58 and 59, cooperating therewith, are so arranged with respect to each other that when the tube 3 moves upward, carrying said grip with it, the tendency of the sprocket-wheel to revolve and run up the chain is prevented by said dogs, and the chain is consequently carried up with the grip, which, as previously specified, imparts rotation to the upper sprocket-wheel, which is connected with the air-pumps. It will be clearly seen from Fig. 9, without further explanatiomthat when the truck-tube descends, carrying with it its grip, downward grip 12 will grasp the chain and carry said chain downward with it, thus imparting f urtherrotation to said sprocket-wheel just referred to. Furthermore, it is manifest that when one side of the endless chain is carried upwarda certain distance the other side will be drawn downward an equal distance, and it will be seen from Figs. 9 and 10 that when the upward grip grasps the chain and carries one side of it up there is nothing to prevent the sprocket-wheel of the downward grip from freely revolving in a direction which permits this necessary movement of that side of the chain. It is likewise manifest that when the down-grip carries its side of the chain with it there is nothing in the construction of the other grip to prevent its sprocket-wheel from freely revolving and allowing its side of the chain to move upward the required distance. When it is desired to stop the pumps, allthat is necessary is to disengage the gravity-dogs from their respective ratchets and turn each one of them over. ends of said dogs, which when in the position illustrated in Figs. 9 and 10 tend to hold them in engagement with their ratchets, will then hold them in a disengaged position, and hence the upward and downward movement of the truck-tube 3 will impart no rotation to the endless chain.

Fig. 17 shows the construction of oneof my air-pumps. Itconsists of the cylinder 60, provided with the ordinarypiston 61 and piston-rod 62. To the lower end of said cylinder is rigidly attached the valve-casing 63, in which is located the ball-valve 64. The lower end of said casing 63 is provided with the cap 65, having a central aperture 66, at the up per end of which is located the valve-seat 67. It will be observed that when the piston 61 moves upward its tendency will be to produce a vacuum in thelower end of cylinder 60. This tendency causes the air to pass in through opening 66, lifting the valve 64, and on up through opening 68 in the top of said valvecasing into the cylinder. WVhen the piston 61 begins to descend, ball-valve 64 prevents the air from escaping at the point it entered and forces ball-valve 69, located in the exit port 70 of the pump, from its seat and passes through the apertures 71 into the air-tank 2, the edge of which is shown by dotted lines, with which said pump is properly connected The upper or weighted by bolts 72, as shown. The valve 69 in the exit-port is normally held to its seat by the spring 73 and operates, as already shown, to freely permit the passage of air from the pump into the air-tank and prevents the air when once in the tank from escaping at that point. The block or cap 74 affords a means of access to the valve 69 and the spring 73.

It will be observed from Fig. 5 that the cranks which operate my pumps are so disposed with reference to each other that while one pump is forcing air into the air-tank the other is simply receiving air from outside. This will permit the pumps to work when there is only slight disturbance of the water. If, however, my tower is located in a place where there is always an abundance of power readily obtainable from the waves, I will make my pumps double-acting, placing'a receiving and an exit port atthe upper end of the cylinder as well as at the lower end, in which case one pump will be made to do double the work that it now performs.-

Having thus fully described the'principles involved in my invention and having illustrated means by which said principles may be applied to actual use, I yet do not wish to limit myself to the exact showing made, but desire protection on all that comes clearly within the spirit and scope of my invention.

What I claim as new, and desire to secure by Letters Patent, is'- 1.
