Application filed May 21, 1915. Serial No. 29,595.

To all whom it may concern.-

Be it known that I, RICHARD A. BEMIs, a citizen of the United States, residing at San Bernardino, in the county of San Bernardino and State of California, have invented certain new and useful Improvements in Wave Motors; and I do hereby declare the following to be a full, clear, and exact de-: scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in wave motors and the prin cipal object of the invention is to provide an extremely simple and practical wave motor constituting an improvement over In Patent N 0. 1,097 ,07 3, issued May 19, 1914.

Another object ofthe invention is to provide a wave motor wherein the use of a cylinder and piston and storage tank is eliminated and in place thereof is substituted a mechanical power generating device rather than compressed air generator as has been previously used in my invention. Y

A further and more specific object of the invention is to provide in a wave motor, a mechanical power transmitting device, a 'belt operating the same, a drive wheel drivwheel for operating the drive wheel, and a plate connected to the ratchet wheel in such a way as to cause the same to rotate in one direction as the force of the waves operate on the plate.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which :v

Figure 1 is a view in perspective showing a wave motor constructed in accordance with this invention.

Fig. 2 is an enlarged view showing the ratchet wheel used in connection with this device.

Fig. 3 is an end view of one of the ratchets.

Fig. 4 is a detail sectional view versely of the plate, and a Fig. 5 is a sectional view on line 55 of Fi 2. 1

ieferring now to the drawings by characters of reference, the numerals 1 and 2 designate the standards provided at their lower ends with points which are driven into the ground to support the whole in position. These standards extend upwardly in paraltrans- I lel relation and are provided with the forwardly extending arms 3 and 4 respectively and the rearwardly extending arms 5 and 6 which project in directions opposite to the arms 3 and 4. The arms 3 and 4 and the arms 5 and 6 are in parallel relation and formed on the arms 5 and 6 near their rear ends are the downwardly inclined arms 7 and 8 respectively, the lower ends of which are formed with the offset portions 9 to form stops against which the vertically extending swinging arms, which will be more fully hereinafter described, rest when in their verticalposition. Pivotally' connected as at 10 to each of the arms 5 and 6 at their rear ends is a relatively vertical arm 11 and the lower ends of these arms 11 are held in spaced relation by means of the shaft 12 carrying the pulleys 13 intermediate its end. A similar shaft 14 is mounted between the arms 5 and 6v and carries the pulley 15 and over these pulleys extend a suitable endless cable 16, as clearly shown in Fig. 1. Secured to one-lead of the cable 16 is float 17 while the opposite lead passes through an open ing formed in said float as clearly shown in the drawings. It will thus be seen that the float may rise and fall with the tide and InOVe in a vertical plane being guided by the endless cable 16. A suitable weight 18 is secured to the lead 19 of the cable 16 as clearly illustrated and attached to this weight is a flexible member 20 passing over a grooved pulley 21 supported between the arms 5 and 6 on a suitable shaft which is positioned near the shaft 14. This cable or flexible connection 20 extends forwardly from the wheel 21 and passes over the wheel 22 mounted near the forward ends of the arms 5 and 6 and the cable then extends downwardly and is provided with the branches 23, the opposite ends of which are connected to the plate against which the waves impinge, which will be more fully hereinafter described. It will thus be seen that a means is provided for keeping the plate near the surface of the water regardless of the tide.

.The plate hereinbefore referred to is designated by the numeral 24'and comprises the arcuate plate 25, which is provided at each end with the bent back portions 26. Suitable floats 27 are secured to each end of the plate and adjacent the bent back portions 26 and are adapted to assist the mechani'sm previously described in holding the plate near the surface of the water. In order to reinforce the plate 24, there is provided the arch plate 28, the ends of which are secured to theplate 2d near the bent back portions or flanges 26. The center of this plate is bowed outwardly as shown and has secured thereto a suitable rod 29, the forward end of which is provided with a suitable loop 30, the use of which will appear as the description proceeds. Secured to the rod 29, near the rear end is a suitable flexible member 31 which passes over the pulley 32 carried at the bifurcation of the flexible member 20. The opposite end of the flexible member 31 is arranged to be attached in any suitable manner tothe bar 29 and it will. thus be seen that the angle of the plate 25 may be adjusted with relation to the water so as to get the full effect thereon. The bar 29 extends through an opening in the plate25 and has secured thereto a flexible member 33, which extends forwardly therefrom and passes over the pulley 34k supported in a suitable frame 35, carried on a shaft 36, mounted between the lower ends of the standards 1 and 2. This flexible member 33 passes upwardly between the standards and over the'pulley 3a which is mounted to rotate the shaft 35 with the movement of the plate 24. The flexible member then passes forwardly between the arms 3 and 4 over the pulley 36 mounted on the shaft 37 which is mounted between the extreme forward ends of the arms 3 and 1 as clearly shown. A suitable weight 38 is attached to the extreme end of the flexible member 33 and is of such size as to return the plate 24 to its forward position after having been struck by a wave.

In order that the power transmitted to the shaft 35 may be converted into continuous rotation, there is provided the specially constructed pulley designated generally by the numeral 39, which is best illustrated in Fig. 2,3 and 5. This pulley comprises a pair of flanges 4E0 which maybe or may not be secured to a hub according to the preferred construction. These flanges 40 are secured to the shaft 35 and are provided with the annular channels 41 in which a suitable felt as is secured. This felt as being provided to convey lubricant to the trun-' niojn of the roller which will be more fully hereinafter described. Each of the flanges isprovided with suitable openings 43, rovid ed with ball races for the reception of the bearing 1% on which the trunnions run.

l The rollers used in connection with this pulley are designated generally by numeral 4.5 and each comprises a cylindrical body 4E6 provided at each end with an axial opening or recess 47, terminating at its inner end in the reduced axial recess 48. A pair of grooves 4L9 is formed in the circular wall of each recess and these grooves are arranged to receive the lugs or ears 50 carried by the clutch halforratchet 51. This clutch half or ratchet cooperates with the clutch half or ratchet 52 which is formed at the inner end of the trunnion 53 and in order to normally hold the clutch half 51 into engagement with the clutch half 52, there is provided the compressed coil spring 54- which is arranged to bear against the inner face of the clutch half 51 to urge the same outwardly. It will thus be seen that [a pulley is provided which when revolved in one direction will drive the belt and when revolved in the opposite direction will letthe belt idle over the rollers and will no? reversethe direction of rotation of the be t.

In order to keep the trunnions53 lubricated, there is provided a suitable standard 55 carrying at its upper end a suitable reservoir 56, provided with the outlet compartments 57 carrying the outlet tubes 58 and it will thus be seenthat the lubricant within the reservoir may be dropped upon the felt, which will conduct the lubricant to the trunnions. 3

Passing over the pulleys 39 and the faces of the rollers a5 is the belt 59, which also passes over the cone pulley 60 which is provided with a plurality of faces for engagement with the belt. This cone pulley is carried on a suitable shaft 61 mounted between the standards 62 and mounted on the shaft 63 below the shaft 61 between the standards 62 are the arms 64, between the upper ends of which is mounted the idler 65. This idler roll 65 is arranged to engage the upper surface of the belt to hold the same, at all times, in frictional engagement with the faces of the pulleys 39 and 60. Mounted on the ends of the shaft 61 is a suitable pulley 66 to which any suitable piece of machinery which is to be driven may be belted.

It will be apparent from the foregoing that in use as the waves impinge against the plate 2%, the same will be forced rearwardly and exert pull on the flexible member 23, thus rotating the shaft 35 in one direction. The weight 38 will cause the flexible memher to be pulled in the opposite direction, thereby returning the shaft and pulling the plate 24 back to its original position, the continuous action of the waves will cause the plate to be in motion constantly and thereby transmit power to the shaft 35, thus causing the rotation of the belt wheel 39. This will cause the belt 59 to revolve the cone wheel 60, thus transmitting power that when the belt travels in one direction the clutches will engage, thereby exerting llU pull on the belt and as soon as the wheel reverses in the direction of rotation, the belt; will idle thereover, thus rotating the shaft 61 in one direction only. It will thus be seen that continued power is supplied to the wheel 66 from which various pieces of machinery may be run.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claim.

l/Vhat is claimed is A wave motor comprising a pair of standards, horizontal arms at the upper ends of the standards extending forwardly and rearwardly therefrom in spaced parallel relation, pivoted legs connected to the rear ends of the arms and extending downwardly, brackets on the arms and extending rearwardly and downwardly from a point intermediate their ends, shoulders at the rear ends of the brackets, said brackets being adapted to limit the forward movement Copies of this patent may be obtained for five cents each, by addressing the Commissioner Washington, D. c.

of the legs with relation to the whole and springs on the arms and connected to the member, a second flexible member connected to the weight, a pulley supporting the last mentioned flexible member near the forward ends of the arms and a plate attached to the opposite end of the last mentioned flexible member and adapted to rest on the surface.
