UNITED STATES OFFICE .JAMES A. J. FLEMING, or niiwronr, OREGON-5'- WAVE-Moron;

To all whom it may concern:

Be it known that 1, JAMES A. J. FLEMING, a citizen of the United States, residing at Newport, in the county of Lincoln and State have invented a new and useful This inventionrelates to a motor to be 0p- I erated b the surf independent of the ebb and flow oft e tide, and has for its object the converting of, the vertical movement given to a float acted on by the waves into a rotatorfy; motion adapted to be transmitted to a she from which power can be transmitted to any desired kind of machinery.

The invention consists of an open well into which the sea waves are admitted and in which a float rises and falls under the impulses of the said waves and of'suitable gearmg drums, and cables by which such rising and fallin is changed into a rotary motion in one direction and practically continuous.

The invention also conslsts of the'novel features of construction and combination of arts hereinafter described, pointed out in the claims, and shown in the accompanying drawings, in which Figure 1 is a plan view of my device. Fig. 2 is a vertical elevation. Fig. 3 is a detail view of a threaded rod and weight, parts being in section. Figx. 4 is a side or end elevation of a drum, s owing ratchet-and-pawl mechanism and controlling means, a lever being shown in section. Fig. 5 is a plan view ofea awl and ratchet, a shaft upon which the ratchet is loose being shown in section. Fig. 6 is a transverse section through the ratchet ratchet-shaft being shown in e evation. Fi 7 is an elevation of a drum and a clutc mechanism. Fig. 8 is a diagrammatic plan of a plurality of piers and floats.

In the drawings, A represents a suitable base or platform, in advance of which project two parallel piers A, though a greater number can be employed when a plurality of floats are to be usedas, for example, in the construction outlined in Fig. 8. Between the 'arallel piers A is formed a space which I wi 1 term the well, and as these Piers are to be built out in the surf it will be obvious that the waves will rise and fall between the walls of the said piers.v On their opposing faces the iers are vertically recessed and the e recesses lined with timbers A". In the well between the tiers works one or Specification of Letters Patent. Application filed July 7, 1905. Serial No. 268,627.

Each float is provided with a vertical rack-stem B having rack-teeth on opposite edges.

Extending from ierto pier is ahorizontal with cross timbers C. J ournaled in bearings on the cross-timbers C The shaftsalso carry pinions Gr, which enga e, respectively, opposite sides of the rate B The shaft C carries 'a drum D and the shaft C drums D and D On the latformA are mounted threeshafts E, G, an G, all parallel to the shafts C and C The shaft E carries drums E and E The drums D and D are loose on their shafts and are coupled to the same by means of a clutch mechanism, as shown in detail in Fig,

a pawl-.and-ratchet mechanism that will be described in detail later and which is shown in Fi 4.

Ca les F and F run over the drums D and E and D. and E respectively. The shaft G is the power-shaft of the device and is geared to the other shafts as follows: A large gearwheel H meshes with a pinion H carried by the shaft G, the gear-wheel being on the shaft E, and a gear-wheel H on the shaft G meshes with a pinion H on a fly-wheel shaft G which carries a fly or balance wheel H.

A tower J on the platformA carries mech anism controlled by a cable J, which winds and unwinds on the drum D and runs over a ulley J hung in the tower J. The cable branches in the tower, as shown at J and the branches J run over rollers J and are conmeshes with a bevel gear-wheel J carried by the shaft G, The threaded shaft, which for convenience will be termed the worm-shaft, carries a horizontal arm L, to which is pivoted a pawl L, that engages the upper ratchetface of the bevel-gear J A drive-pulley M is also carried by the shaft G.

It will be obvious that the rack-stem B has a reciprocating motion rising and falling with the float B, to which it is pivotally con nected to avoid strain by reason of one end of the float rising more rapidly than the other, and that the pinions C 1 will be rotated first in one direction and then the other. To give continuous rotation in one direction tu the Shafts E, G, and G, the following devices are employed: .The drums E and E as previous rate et K is fixed on the shaft E, adjacent each drum, and pawls K are pivoted to the drums and ngage the ratchets K. A split spring-band K is adapted to bear on the awls K and throw them out of o eration or into 0 eration, as may be desire and each band has converging arms K which pass through a slot in a lever K". By sliding the slotted end of the lever toward the drums the arms K are pressed closer together and the bands tighten against the outer ends of the pawls, lifting their inner ends out of engagement with their respective ratchet. It will now be obvious that by reversing the rotation of the drums E and E the pawls on one drum will engage their ratchet during rotation in one direction and slip during reverse rotation of the drum, and that the pawls on the opposite drum will be in engagement while the pawls on the other drum are slipping, andas the drums are driven from the drunisD and D, and these drums are on separate shafts driven from opposite sides of the rack-stem B that-the drums E and E will rotate in opposite directions, and that the.

same direction of rotation will be given the shaft E. v

The operation of the device isas follows: The float- B will rise and fall with the incoming and going out of the waves, and the vertical movement of the stem B will rotate the pinions The drums D and D being rotated from their shafts C and G which are rotated through. the mediums of the pinions C the drums E and E will be rotated by the cables F and F. The gear-train described will impart this rotation to the shafts G and i. The drum D will also raise and lower the weight J through the winding and unwinding of the cable J, the weight being raised as the float rises and falling by reason of its own weight as the float descends. T he falling motion of the weight will be retarded by the spiral worm-shaft J", which is rotated by movement of the weight, and during the downward. movement of the weight the stated, are loose on their shaft E. A

worm-shaft is conne ted by its pawl L to th ratchet of the bevel gear-wheel J and is performing work by aiding in drivin the shaft G. During upward movement of the weight J the pawl L will slip on the ratchet J This isnecessary, as the worm-shaft J is then rotating in a direction the reverse of that of the shaft G. a

It will be obvious that the float or floats alone are sufficient to drive the mechanism during their upward movement, but while falling the weight of the float alone would be insuflicient to hold the machinery driven at a fixed speed, and, furthermore, that the rise and fall of the floats is irregular and not at a constant either as to height of rise or speed of their vertical movement. To give to the de* vice, therefore, a more constant speed than could be had with the floats onl I employ the fly-wheel H and the weight (i the latter erformingwork during its fall as the floatfalls and the fly-wheel carryin the shaft G over the period of inaction at t .e moment of the float reaching its highest or lowest point of travel. The piers are so placed that. the deivice can be operated'at various stages of ti e. K to the levers K and when the speed be- A governor K is connected by cablescomes excessive the governor will draw upon the levers so as to tighten the bands K on the pawls K and lift them from engagement with rt tchets K thus permitting them to slip until the speed has been reduced, Whenthe governor, which may be of any ordinary make, will return the levers to their proper position or if connected by single cables, as shown in the plan view in Fig. 1, the governor will permit the cables K to slacken and the spring-arms li will serve to force the levers to their normgipositions.
