COMPLETE SPECIFICATION.
Improvements in Automatic Ship Pumps and Wave Motors.
We, WILLIAM HERBERT WENTWORTH HAMILTON and AUGUSTUS M. MAHANY,
both of White Hills, in the County of Mohave, and Territory of Arizona, United
States of America, Gentlemen, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
.
Our invention is in the nature of an automatic ship pump and wave motor, the
object of the invention being to provide mechanism whereby the fore and aft
motion of a ship may be utilized to operate the pump, either for the purpose of
emptying the hold of leakage, pumping sea water aboard, or for any other purpose
for which a pump may be utilized, the principle of the mechanism being also
applicable to motors to be operated by the waves of the ocean.
With this object in view, our invention consists in the improved construction,
arrangement and combination of parts hereinafter fully described and afterward
specifically pointed out in the appended claims.
In order to enable others skilled in the art to which our invention most nearly
appertains, to make and use the same, we will now proceed to describe its con-
struction and operation, reference being had to the accompanying drawings,
forming part of this specification, in which:-
:-
Fig. 1 is a perspective view of a ship's pump constructed in accordance with
our invention.
Fig. 2 is a similar view of an apparatus of the same kind of a somewhat modified
form.
Like letters of reference mark the same parts wherever they occur in the
different figures of the drawing.
Referring to the drawing by letters, A indicates the base, upon which a double
acting pump B, is mounted, said pump being provided with an air chamber C,
and double ended piston rod D
E indicates a trough mounted upon standards F, secured to the base A and
braced by rods G, connecting the corners of the trough with the corners of the
base.
H and I indicate levers, pivotally mounted in brackets I', secured to the
base A, passing upward through the trough E, widened at their upper ends as
at H and I", and pivotally connected to the outer ends of the piston rod 1).
Jindicates a ball seated in the trough E between the enlarged ends H" and I"
of the levers H and I.
The foregoing description is of a device as illustrated in Fig. 1, and its opera-
tion may be described as follows:
The base A, either resting upon the deck of a ship or forming part thereof,
the trough E extending fore and aft, the fore and aft movement of the ship will
cause the ball J to roll from end to end of the trough. When it rolls in one
direction it will press the lever H outward by coming in contact with its upper
end H, while its movement in the opposite direction will have a similar effect
upon the lever I by reason of its contact with its upper end J. When the

page_text: lever I moves outward, the lever I moves inward and vice versa, the two revers
being connected by the piston rod D.
The pump being double acting will draw and discharge water no matter in
what direction the piston 1) is moved by the levers, so that any motion of the
ball against either of the levers will cause the pump to operate.
In the construction shown in Fig. 2, the base A, pump B, air chamber C and
piston D will be of the same construction as that herein before described.
The trough E will also be of similar construction, but mounted below the
pump upon the base A, the pump itself being supported upon a cross-bar or
beam K, secured in upright end frames L and L', provided with longitudinal
slots, M and M', through which levers and 1', pass, said levers being some-
what similar in construction to the levers H and I before described, and being
pivoted to brackets 01 and P', projecting inward from the end frames L and L.
Below their pivots the levers and P are enlarged or broadened out as at 01
and P and rest partially in the trough E in the path of the ball J.
At their upper ends, the levers O and P are connected by links Q and Q', .to
levers Rand S, which are pivotally attached to brackets R¹ and S¹, projecting
from the pump casing in either direction, and have their lower ends pivotally
connected to the outer ends of the piston D.
As the ball is rolled in either direction in the trough by the movement of the
ship, it will strike the enlarged ends and P of the levers O and P and cause
said levers to be oscillated on their pivots. When the ball strikes the lever Ol
it will press it outward, causing its inner end to move inward, push the upper
end of the lever R inward and throwing its lower end outward and drawing the
piston rod D to the right.
The opposite end of the piston rod will, through the medium of the lever S
and connecting rod Q, also oscillate the lever l', at the same time throwing its
lower end P inward, ready for the impact of the ball J when caused to move in
the opposite direction by the movement of the ship.
As in the former construction, the movement of either lever will cause the
movement of the piston rod, and the pump being double acting every such
movement will cause it to draw and discharge water. When thus used as a ship
pump, the device will be entirely automatic in its operation. It may be placed
anywhere on board the ship so that the ball trough is located lengthwise of the
ship, and it will be especially adapted for use on sailing ships or other vessels
not provided with power pumps.
T, T, indicate bumpers of rubber or other suitable material to receive and
cushion the levers H, I, and O, P, at the outer end of each stroke. The ball is
secured against rolling out of the groove laterally, by means of railings U. The
levers O and P may be extended as at V, V, to form handles so that the pump
might be worked by hand if desired. The pumps may be placed athwart ship
if desired.
As illustrated and described, the ball may be located in a trough above or
below the pump, the operation being substantially the same, and the pump
being capable of use as a fire pump, to draw water over the side, and to pump
bilge water or leakage from the ship.
The principle of our invention may also be utilized as a wave motor, the move-
ment of the levers under the action of the ball serving to furnish power for any
desired purpose.
Our pump or motor may also be erected alongside of piers, etc., near the shore,
to furnish power. The frame, pump, ball and other parts may be made in any
approved manner or of any desired material, and while we have illustrated and
described what we now consider efficient means for carrying out our invention, we
do not wish to be understood as limiting ourselves to the exact details of con-
struction shown and described, but hold that such slight changes or variations as
might suggest themselves to the ordinary mechanic, would properly fall within
the limit and scope of our invention.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
:
1. The combination with a double-acting pump provided with a piston rod pro
jecting at each end, of a pair of levers, a trough through which the levers pro-
ject and a ball seated in the trough between the levers, substantially as described.
2. A double-acting pump, mounted to be carried upon the deck or other part
of a vessel, in combination with a trough arranged in a fore and aft line with
relation to the ship, a ball seated in said trough and adapted to be rolled fore
and aft by the motion of the ship, a pair of pivoted levers attached to the piston
rod of the pump at each end and projecting through the ball trough in the path
of the ball, and suitable supports and braces for the trough, substantially as
described.
