SPECIFICATION forming part of Letters Patent No. 460,812, dated October 6, 1891.
Application filed September 24, 1890. Renewed August 21, 1891. Serial No. 403,282. (No model.)
To all whom it may concern:
Be it known that I, HENRY P. HOLLAND, a citizen of the United States, residing at the city and in the county of San Francisco, and
5 State of California, have invented certain new and useful Improvements in Wave-Power Motors; and I do hereby declare the following to'be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly ap-" pertains to make, use, and practice the same.
My invention relates to that class of apparatus adapted for utilizing the power afiorded by the movement of waves and tides, and
I which is commonly known as a wave-power motor.
The object of my invention is to provide improved means by which the regular and irregular horizontal and vertical movements of abody of water will all be utilized without the loss of power and motion.
The above statement sufficiently explains the purpose of my invention and of the apparatus in which I have embodied it; and
z 5 said apparatus consists, essentially, of abuoyant float having a free motion upon a body of water beneath a pier or like structure and having connections to suitable mechanism upon said structure, whereby its vertical rise 0 and fall and its approximately horizontal swing will set and maintain said mechanism in operation for the production and transmission of power. This feature of myinvention, whereby all the movements of the float,
whether horizontal or vertical, continuous or interrupted, regular or irregular, Wlll be transmitted for power-producing purposes, distinguishes it from all others with which I am acquainted.
For a clear comprehension of the entire apparatus, reference must be made to the following detailed description and to the accompanying drawings, in Wh1ch Figure 1 is a front elevation with one each of the compressors G and K removed. Fig. 2 is a plan view showing one of the central sheaves j audits bearing removed, and also showing the upper part of the pler at one end removed and one end of the truss beam broken away so as to illustrate more clearly the position of its guide-rollers c c. Fig. 3 is an end elevation. Fig. l is a cross-section on the line on m, Fig. 2, showing the interior of the float with its suspension devices in elevation.
A represents a pier built out from the shore and composed, preferably, of horizontal and upright timbers and suitably braced to form a structure of suflicient strength to sustain the power producing and transmitting devices. The interior of the pier is open to permit a free range of movement in all directions of the suspended buoyant float B, which rests in the water, and receives and conveys the various motions of the waves, tides, or surf, as the case may be. This float is a hollow shell constructed of boiler-iron or other suitable material, and having, preferably, the cross-section illustrated in Fig. 4. The float is suspended from truss-beams C, which are illustrated, Fig. 2, each of which is provided at both ends with a pair of friction-rollers c c, which bear upon upright timbers of the pier structure. Secured to each of these trussbeams is a horizontal rod (1, upon which is pivoted the suspension-hangers c of the float B. This hanger consists ofcentral uprights 0 which pass down through the shell and are secured to its bottom, and inclined braces 0 attached to the exterior of said shell. Theshell 8c is thus allowed to swing freely within the limits permitted by the loose chains 6, Fig. 3, connected to it and to the pier. The beams C are thus sustained by the buoyancy of the float, and are permitted to move freely up and down upon the uprights of the pier whenever the motion of the water raises the float. They are further guided, however, by supplemental frames E, Fig. 3, built upon and above them, and provided with rollers f, which bear upon a guide-frame D, attached to the upper part of the pier structure, such guide-frame having the lower end of the timbers composing it inclined, so that the lower rollers f may readily bear upon it when 9 5 the float is raised sufliciently to cause them to do so.
Upon the upper part of the pier structure and near each end are pivoted a pair of walking-beams F, having at one end a pitman con- Ioc nection g, to the truss-beams, and at the other a rod g, to transmit the power to some special mechanism of any desired kind. In the present case I have shown the rod g as jointed to the piston-rod of an air-compressor G; but
' it is evident that the motion of the rod can be transmitted to a crank-shaft, or to any other well-known means for translating its vertical reciprocation into some other application of power. Should the movement of the float be directly vertical all the trussbeams will be raised together and all the walking-beams and connections operated at the same time. Should one end only of the float be lifted, only the truss-beam at that end will be raised, "and the'w'alking-bea'ms connected to that end be operated.
The truss-beams are counterbalanced by weights H, suspended from ropes or cables h, connected to said beams, and passing over elevated sheaves h on the pier.
If so desired, the sheave rods or axles h may be extended so that the rotary motion thereof may be transmitted and utilized for power purposes.
At any vertical motion of any part of the float two at least of the four pumps shown will be operated.
The motion produced in the float by the horizontal impact of the waves is transmitted to a rolling truck I, running between upper and lower guide-railst't'at the top.of the pier. This truck has connected thereto the upper ends of arms L 01', which extend downwardly with a space intervening to receive a central rod d, said rod sliding vertically therebetween. A suspension-hanger m similar to the end hangers, and consisting of a central upright m, and inclined braces m m is connected to said central rod (1, and also connected to the truck through the intermediary of inclined beams n 'n and arms 0." 1'. To each end of the truck is attached a chain 1 which, after passing over a sheave j, Fig. 4, is secured to the weighted piston-rod 7c of another pump K. The vertical movement of this piston-rod is insured by forming its weight 7a with a stud k which travels in a guide Z, forming part of or secured to one of the uprights of the pier,Fig. 2. The horizontal swing of the float is limited, as before noted, by loose chains, and the amount of movement per mitted it will depend upon the length of travel required in the truck to produce the requisite movement of the compressor-piston or whatever device may be employed instead of such compressor.
From the outer ends of truck I may extend the piston-rhds i which work in cylinders, (not shown,) so thatwith each lateral move ment of the truck I not only secure the oper ation of the piston-rod 76, but also pistonrod i The sheave-axles it may be extended similar to axles 7L2, so that power to be derived from sheaves j may be utilized.
From the above description it will be seen that the conversion of the horizontal movement into power is due to the fact that the middle-support on the float is longer than the two end supports, so that the end pivots cl act as fulcra for the lever or central hanger m. This, in connection with the fact that the end supports or hangers 0 do not have any lateral movement and the central support or hanger me does have such movement, is what allows and causes the horizontal movement to truck I.
By reference to Fig. 2 it will be seen that I have provided six separate air-compressors, two of which at least will be operated by any movement of the buoyant float. -A direct vertical lift of the float will operate the four compressors at the ends. A directvertical lift of one end of the float will operate the pair of compressors at that end. A direct swinging motion of the float will operate the middle pair of compressors through the rolling truck, and acombined vertical and swinging motion will move the pistons of all the compressors simultaneously. There is thus practically no lost motion or power in the apparatus, as in wave-powers generally heretofore used, in which the horizontal impact alone has been utilized.
I am aware that minor changes may be made in the arrangements of parts and details of construction herein shown and described without creating or necessitating a departure from the nature and scope of my invention.
Having thus described my invention, what lclaim as new, and desire to secure protection in by Letters Patent of the United States, is 1. A wave-power consisting of a suspended buoyant float having a free horizontal and -vertical motion, in combination with mech anism connected to each end of said float foiutilizing it-s vertical motion of either or both ends for the production of power, and an independent mechanism connected to said float for utilizing its horizontal movement, substantially as set forth.
2. A wave-power motor consisting of a suspended buoyant float having a free horizontal movement, frame attached to the float and connected to the movable truckframe, and
truck working upon the pier-frame and of the.
cables for receiving the movement of the float through the medium of the truck and transmitting the same for power purposes, substantially as set forth and described.
3. A wavepower motor consisting of a suspended buoyant float having a free vertical motion, in combination with the movable platform, uprights projecting therefrom forming guideways, and pivoted rods secured to the float-platform and connected to the horizontal beams pivoted to the pier-frame, said beams being adapted to receive and transmit the motion of the float and of the counter-e balance-weights secured to the platform, substantially as set forth and described.
4. Awave-power motor consisting of a buoyant float suspended within an open pier, platform secured to the outer ends thereof, guideuprights located thereon, pivoted rods con nected to rods pivoted to the pier-frame,said
ITO
beams being adapted to transmit the vertical movement of the float, a frame secured to the float, a movable truck provided with depending uprights, forming guides and having pivotal connection with the float-frame, said guides and truck adapted to move together laterally, and cables or chains connected to and adapted to transmit the motion of the truck for power purposes, substantially as set forth.
