DAVID K. BRYSON, OF PITTSBURG, PENNSYLVANIA.

WAVE-POWER MOTOR.

SPECIFICATION forming part of Letters Patent N 0. 711,758, dated October 21, 1902.

Application filed February 7, 1902. Serial No. 93,005. (No model.)

To all whont it may concern: 7 Be it known that I, DAVID K. BRYSON, a citizen of the United States of America, residing at Pittsburg, in the county of Alleghenyand State of Pennsylvania,have invented certain new and useful Improvements in Wave- Power Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in wavemotors, and has for its object a motor which will utilize the horizontal as well as the vertical motion of the waves.

My invention has for its further object a wave-motor wherein the direction of the propeller means shall at all times remain inva riable, irrespective of the direction in which the waves are running.

The invention further resides in the simplicity and economical features of construction, the comparative inexpense to manufacture, and the efficient operation.

With the above and other objects in view the invention consists in the novel combina tion and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims. 7

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this speciflcation,and wherein like numerals of reference indicate like parts throughout the several views,in which-'- Figure 1 is a perspective view of my invention, showing the staggered arrangement of the series of motors. Fig. 2 is a central vertical sectional view taken on the line 22 of- Fig. 1. Fig. 3 is an underneath plan view of the guide-rollers carried by the float.-' Fig. 4 is a side elevation of one of the sprocketwheels. Fig. 5 is ahorizontal sectional View taken on the line 3 3 of Fig. 2. Fig. 6 is a horizontal sectional view on the line 4 4 of Fig. 2. Fig. 7 is a top plan View of the rocking frameand the guide-rollers carried thereby.

In order to afiord a'rigid structure for the purpose of supporting the series of power units, I embed within the bed of the body of water the motion of which is to be utilized to actuate the power units a series of standards 1, carrying suitably-spaced beams 2 and a transverse bar 3 at their upper end.. This side of the float or casing 12.

rigid frame may be constructed in various manners, and the material employed in connection therewith may also vary. Shaft-supports 4 are carried by the frame and have a revoluble shaft 5, carrying a fly-wheel 6 and a drive-wheel 7, connected thereto.

Between the beams 2 is mounted a series of rocking frames 8, which are pivotally mounted as shown at 9. Mounted within this rocking frame are two pairs of diametrically-arranged guide-rollers 10 11, the purpose of which will be fully hereinafter set forth.

' The float or casing 12 is perfectly air-tight and is preferably of an annular form with convexed upper and lower faces. The upper face of this float or casing 12 has a suitable inlet 14: therein, closed by means of the plug 15, whereby access to the interior may be had in order to place a suflicient quantity of water or any other liquid therein, the quantity of liquid varying according to the specific gravity of the same, but in all cases being such as-will cause the float or casing to have substantially one-half of its height submerged in the body of water. To the lower side of this casing is a depending flange 15, surrounding a series of antifriction-rollers 16, which are revolubly carried by the bottom of the float or casing 12. A like flange 17 is carried by the upper side of the casing and likewise surrounds a series of antifrictionrollers 18, revolubly carried by the upper A tube 19 has its upper end carrying a yoke 20, the upper ends of the yoke being pivoted to the sides of the rocking frame 8. The lower end of this tube 19 carries a collar 21, the lower end 22 of-which is bent outwardly to form an annular flange which engages a series of outwardly-extending fins 23, carried by the collar 21. Downwardly-extending brackets 24, carrying antifrictio'n-rollers 25, are carried by this annular flange 22 of the collar 21.

To the drive-shaft 5 is keyed a pair of ratchet- wheels 26 and 27,- which are adapted to be engaged by the spring-pressed pawls 28 and 29, carried by the loosely mounted sprocket- wheels 30 and 31 of the drive-shaft 5. The loosely-mounted sprocket-wheel 31 has a chain 32, carrying a suitable weight 33 at its one end mounted thereon, the other end of the chain passing through the tube 19 and carries the ordinary chain 34: at its lower end this chain passing downwardly through the collar 21 between the several antifrictionrollers 25 and carries a hook 35 at its lower end which is engaged by the staple 36 on the upper end of the post 37, the latter being rigidly affixed in the bed of the body of water.

To the upwardly-extending flange 17 of the float or casing 12 is pivotally secured a yoke 38, the upper end of which has secured thereto a sprocket-chain 39, which extends upwardly between the guide-rollers 10 and 11 over the loosely-mounted sprocket-wheel 31 and from thence passes downwardly and carries a weight 40 at its lower end.

It will be noted that the float 12 is slidingly mounted upon the tube 19 by means of a sleeve 41, which is rigidly attached to the float or casing 12. This casing in its movement upon the tube 19 will be materially furthered in its ease of action by means of the guide-rollers l6 and 18, which contact with the periphery of the tube 19. I desire to call attention to the fact that any number of these floats may be employed in connection with the shaft in order to propel the latter, the

number being dependent upon the amount of power desired. '1 find when more than one float is employed that it is highly advantageous to give the same a zigzag or staggered arrangement,as clearly illustrated in Fig. 1 of the drawings.

We will assume for the purpose of illustration that the several floats have been placed in their respective positions, as previously described, in which instance the latter are in a position to utilize the various motions of the waves. The up and down motion of the waves, or rather the vertical motion of the same, will cause the float 12 to ride up and down upon the tube 19, which will cause the weight 40 to move therewith. Upon the upward movement of the float the sprocketchain will propel the sprocket-wheel in the direction from left to right, and upon the downward movement of the float the springpressed pawl will engage in the teeth of the ratchet-wheel and cause the shaft 5 to revolve. The invention also aims to utilize the horizontal motion of the waves-that is, the movement from said right to left or left to right or in a plane transverse to that direction, which movement of the float will cause the tube to move therewith, the tube moving about its pivoted connection with the rocking frame. This motion of the tube and the float will cause the rollers 25 to engage with the chain 34:, which is rigidly secured at its lower end to the post 37, and move the chain in a horizontal direction, which is made possible by the rocking frame having a pivotal movement. This horizontal motion of the tube and the float will cause the sprocketchain 32 the ratchet-wheel, and thus revolve the shaft 12. It will be noted that when the vertical movement of the waves is utilized the downward motion of the float is the power-stroke, causing the pawl to engage in the ratchetwheel and revolve the shaft 5, and when the horizontal motion of the waves is utilized the outward movement of the float is the powerstroke, the weights in both instances merely serving to take up the slack in the sprocketchain, thereby causing the latter to engage in the teeth of the sprocket-wheels at all times. The fins 23 serve the purposeof steadyingor retardin g the horizontal motion of the tube carrying the float when it is desired to utilize the vertical movement of the float only, which relieves the frame of any strain which would result were the lower end of the tube rigidly affixed to the bed of thebody of water. I desire to call attention to the fact that this double action of the motor may be carried on simultaneouslythat is, the tube and float may move to the horizontal direction simultaneously with the up-and-down movement of the floatwhich will utilize both the vertical and horizontal motion of the waves and cause delivery of power on the shafts to be more constant, the power from the downstroke commencing where the power from the outward or horizontal stroke stops.

1' have illustrated in the accompanying drawings the most practical embodiment of my invention; but I do not wish to limit myself to the exact construction as shown and described, since it is obvious that various minor changes in the details of construction and combination of parts may be made without departing from the general spirit and scope of my invention.
