Application filed June 24, 1911.

Serial No. 635,197.
To all whom it may concern:
Be it known that I, FRANK BROWN, a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in ave-Motors, of which the following is a specification.
My said invention consists in certain improvements in the details of construction and arrangement of parts of wave motors whereby such a motor is provided which will be simple in structure, but certain in operation under all conditions of the tide, or waves, all as will be hereinafter more fully described and claimed.
Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 is a View showing the motor and supporting frame in end elevation, Fig. 2 a side elevation thereof, Fig. 3 a detail view on an enlarged scale of the rack and pinion operating mechanism, Fig. 41 a cross section on the dotted line l l in Fig. 3, and Fig. 5 a detail view showing one of the pinions in elevation and illustrating the ratchet and pawl connection with the power shaft.
In said drawings the portions marked A represent the frame supports, B the power shaft and C the buoy. The frame consists of the posts, or supports, A. which may be of reinforced concrete, metal, or any appropriate material and are suitably set and anchored in the bed of the body of water, the waves of which are to be utilized for driving the motor. The tops of said posts are connected by suitable timbers, or a platform, A. While I have shown only a single buoy, and, therefore only one end of the frame, it will be understood that any number of buoys may be connected with the main shaft in the same manner as illustrated for this one and that the frame and shaft are extended as may be necessary to accommodate the number of buoys desired. The shaft B is journaled in suitable bearings on the top of brackets, or standards, 10 mounted on the top of platform A and a fly wheel 11 is mounted on said shaft for a purpose to be presently described.
The buoy C is preferably a steel shell of suitable size and form for the purpose and is provided with an aperture closed by a suitable plugs, or valve, 0 through which the shell may be loaded with sea water, or
other material as may be' desired to obtain the proper weight to operate with best results under any prevailing conditions of the sea. Said buoy is mounted between vertical guide rails, or tracks, 12, which are appropriately secured to the frame being held thereto by appropriate engaging flanges. A heavy cross bar 13 extends from side to side across the top of each buoy and an angle-iron 141 pivoted to the center thereof with its ends extending outward oppositely from its pivot. Rack-bars 15 are pivoted at their lower ends to the outer ends of said angle-iron 14 and extend upwardly to a sufiicient height above the platform A for the purpose and their tops are pivotally con nectecl to a cross-bar 16.
Mounted on shaft B between the adjacent edges of rack-bars 15 are pinions 17 and 18 which are mounted to rotate loosely on the extended ends of the hub of a ratchetwheel 19 which is keyed to shaft B. Each of the pinions 17 and 18 are formed with a circular recess in their adjacent faces at their centers, the recesses being of a diameter sufficient to receive the ratchet-wheel 19, onehalf of the thickness of the ratchetwheel being thus inclosed in the recess of pinion 17 and the other half inclosed in the recess of pinion 18. Each of the pinions 17 and 18 have a pawl 20 pivoted in a recess adjacent to the edge of said ratchet-wheel, the pawl of one pinion being adapted to engage with one side of the toothed face of the ratchet 19 and the pawl of the other pinion being adapted to engage with the other side. The rack-bars 15 are formed as best shown in Fig. 1, each having teeth on one side only of its inner edge, the edge of one rack-bar bearing teeth being on the opposite side from the edge of the other rackbar bearing teeth so that the teeth of one rack-bar engage with pinion 17 on one side of shaft B while the teeth of the other rackbar engage with pinion 18 on the opposite side of shaft B. The rack-bars and pinions are embraced in a frame composed of crossbars 21 and 22 mounted on opposite sides thereof and suitably supported from the frame. The outer ends of said cross-bars are connected by bolts 23 and held the proper distance apart by distance sleeves 25, on which are mounted anti-friction rollers 25 against which the rack-bars bear. By this construction the operating gears are held in a compact form and the rack-bars are enabled to operate freely and at the same time true and steady. Said rack-bars are of a length to extend above the platform A and shaft 13 to a height suflicient to operate under all conditions of the tide.
In operation, as will be readily understood from the foregoing description, one of the rack-bars operates as a driving rackbar during the upward motion of the buoy, while the other rack-bar becomes the driving rack-bar during the downward motion of the buoy. Pinions 1'7 and 18 are thus alternately locked to ratchetwheel 19 by pawls 20 to drive the shaft 13, the pawl of one pinion sliding freely over the ratchetface of the ratchet-wheel while the rack-bars are moving upward and the pawl on the other pinion sliding freely over the ratchetwheel during the downward motion of the rack-bars. Under the momentum of flywheel 11 the speed of the shaft may be maintained during the shift of the drive from one side to the other, or even increased beyond that generated by the movement of the buoys the forward movement of said shaft being free. By extending the frame and the shaft and multiplying the buoys any power desired can be readily generated and by suitable gearing transmitted wherever it may be desired to use it as will be readily understood.
Having thus fully described my said invent-ion, what I claim as new and desire to secure by Letters Patent, is:
1. A wave motor comprising a frame, a power shaft journaled in bearings on said frame, a ratchet-wheel keyed to said shaft, a pair of pinions mounted torun loosely one 011 each side of said ratchet-wheel, pawls for connecting said pinions with said ratchetwheel, a buoy mounted to be operated by the rise and fall of the waves, rack-bars pivoted to said buoy and engaging one with one of said pinions on one side of the shaft and the other with the other of said pinions on the other side of said shaft, and a guide frame surrounding said pinions and rack-bars, substantially as set forth.
