PUMP.
Specification of Letters Patent.
Patented Sept. 25, 1906.
To all, whom it may concern.-
Be it known that we, ARTHUR E. PRAY, residing at Rome, and Lori M. PHILBRICK, residing at Mount Vernon, in the county of Kennebec and State of Maine, citizens of the United States, have invented a new and useful Pump, of which the following is a specification.
This invention relates to pumps, and has for an object to provide a pump arranged to be operated by wave-power and embodying new and improved features of simplicity, utility, economy, and efficiency.
A further object of the invention is to provide a pump which requires no attaching to the bottom or other stationary objects, being secured only sufficiently to prevent its [loatmg away.
With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter fully described, shown in the accomp anying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made without departing from the spirit or sacrificing any of the advantages of this invention.
In the drawings, Figure 1 is a view of the pump in side elevation. Fig. 2 is a vertical lon itudinal sectional view of the um).
Fig. 3 is a transverse sectional view taken on line 3 3 of Fig. 2. Fig. 4 is a detail sectional view of one of the pistons.
Like characters of reference indicate corresponding parts in all of the figures of the drawings.
In its preferred embodiment the improved pump forming the subject-matter of this application comprises a float 10, of any approved form, size, and construction and here shown as of barrel shape. From the under side of the float is suspended a shell 11, of any approved form, size, and material and here shown as a cylinder open at the top and bottom and suspended from an eye 12, secured axially at its upper end to the radial braces 13. The braces 13 are bent and extend downwardly along the sides, as the strips 14, to the middle of the shell, where they are rigidly secured to a hoop 15, encircling the shell.
The shell is provided with a ring 16, secured about and within its upper end, and a similar ring 17, similarly secured in the lower end. l/Vithin the shell is also mounted a frame, comprising the side pieces 18, somewhat shorter than the interval between the rings 16 and 17 and held in circumferentiallyspaced juxtaposition to the inner surface of the shell by radial arms 19 adjacent the top and similar arms 20 adjacent the bottom. Upon the radial arms 19 and 20 are respectively secured diaphragms or heads 21 and 22, substantially closing the shell, but movable therein together with the frame, the extended extremities of the side pieces 18 being positioned to engage the rings 16 and 17, and thereby limit the movement of the frame in each direction.
Axially upon the head 21 is secured a cylinder 23, with an open end downward, and to the lower head 22 is similarly secured a similar cylinder 24, with its open end upward and in alinement with the cylinder 23. Within the cylinders are disposed reciprocating pistons of the solid type, as 25,which are connected by a rigid piston-rod 26, having centrally a ring 26*. A cross-arm is secured at its opposite ends to the middle of the shell, as by the nuts 28, and comprises the sections 27 and 27*, united, as by the bolts 27 between which the disk 27" is pivoted, as by the bolt 27 the said disk filling the ring 26. The cylinder 23 is provided with any approved form of inlet and outlet check- valves 29 and 30, respectively, while the cylinder 24 is similarly provided with checkvalves 31 and 32. The outlet check-valves and 32 are connected by a pipe 33 which communicates with a flexible delivery tube or conduit 34. ithin the frame are secured one or more buoyant members, as 35 and 36, of sufficient buoyant capacity to float the frame and its rigidly-associated parts, if unimpeded. Adjacent the top of the shell rings 37 are attached to the strips, in which maybe engaged anchorlines, as 38, to prevent the device floating away. While the pistons 25 may be of any approved construction, they each are preferably formed with a peripheral groove 39, having openings 40 communicating with an axial opening 41. Within the groove is disposed a split ring 42, proportioned to leave a space between it and the bottom of the groove.
In operation the pump is suspended, as shown in Fig. 1. As waves pass the float 1O rises and falls in the usual manner, and with it the shell 11, which carries with it the pistons 25. The heads 21 and 22 offer resistance-surfaces to the water in which they are suspended, so that as the shell rises and falls by the action of the waves, carrying with it the pistons, the frame and the cylinders are by the water held approximately stationary and the pistons reciprocate within the cylinders and pump water in the well-known manner and discharge it through the flexible pipe 37, which may be connected with any approved pipe or the like. The action of the pistons against the water contained in the cylinders forces the water into the opening L1 and through the openings 40 into the groove 39 to extend the split ring at each stroke, the ring contracting by its own resiliency on the return stroke, whereby the piston engages the cylinder with operative friction only during the pumping half of the stroke. It will be readily seen that the anchors and anchorropes play no part in the operation of the pump and are preferably run to a considerable distance from the pump, so as to allow for a general rise and fall of the water due to tides or the like.
Having thus described the invention, what is claimed is 1. A wave-motor comprising a float, a cylinder member and a piston member, one of said members being supported by the float, and resistance-surfaces for engagement with the water and disposed above and below and movable with the other member. 2. A wave-actuated motor comprising a float, a cylinder member and a piston member, one of said members being supported by the float, resistance-surfaces for engagement with the water and disposed above and below and secured to the other member and movable therewith.
3. A wave-actuated motor comprising a float, a piston suspended from the float, resistance-surfaces carried by but movable relative to the float, and cylinders interposed between and rigidly connected to the resistance-surfaces and embracing the piston ends.
4. A wave-actuated pump comprising a float, a shell suspended from the float, associated cylinder and piston members within the shell and with one of the said members rigidly connected therewith, a resistancesurface mounted and movable within the shell and rigidly connected with the other member.
5. A wave-actuated pump comprising, a float, a shell suspended from the float and open. at opposite ends, a frame movably mounted within the shell and provided with resistance-surfaces substantially closing the open ends and an associated cylinder and piston within the shell and frame and with said cylinder and piston rigidly secured one to the shell and the other to the frame.

8. A wave-actuated pump comprising a float, a shell suspended from the float, a buoyant member within the shell, resistancesurfaces carried by the buoyant members and movable within the shell and an associated cylinder and piston within the shell and one secured to the shell and the other to the buoyant member.
9. A wave-actuated pump comprising a float, a shell suspended from the float and open at each end, a frame movably mounted within the shell and having a head at each end substantially closing the shell, a buoyant member within the shell and connected with the frame, an associated and coacting. piston and cylinder within the shell and frame and rigidly connected one with the frame and the other with the shell, means to limit the movement of the frame and a conduit communicating with the cylinder.
10. A'wave-actuated pump comprising a float, a tubular shell suspended from the float and open at the top and bottom, a frame movably mounted within and con forming substantially to the form of but shorter than the shell, a buoyant member secured within the frame, an associated and coacting cylinder and piston mounted vertically within the frame, a cross-bar secured at its end to the shell and at its middle to the piston, means rigidly connecting the cylinder to the frame, heads carried by the frame substantially closing the shell, means to limit the movement of the frame and a conduit communicating with the piston.
In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
