Swift, do hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement (that is to say):-
A cylender or case of suitable form and size, in which shall be worked a
rod and piston, plunger or projector also of suitable form and size, the cylender
or case to be open at both ends for ingress and egress of water, and to be
surrounded with an outer cylender or case open only at one end, the inner
cylender or case in which shall be worked the rod and piston plunger, or
projector to be secured to the back or closed end of the outer cylender or case
by means of the forward or projecting motion of the rod and piston plunger,
or projector to force a stream of water from the mouth of the inner cylender
or case, and by means of the return or backward motion of the rod and piston
plunger or projector to force a stream of water through the outer cylender or
case, causing both streams of water to flow parallel to or in a line with the
keel of any such ship, vessel, boat, or other craft to which this Invention may

page_text: be applied, the outer cylender or case to be supplied (if found necessary) with
one, two, or more valves for the ingress of water, which valve or valves shall
.be self-acting by the pressure of the water, or be made to sufficiently act by
the use of suitable machinery; or a cylender or case of suitable form and
size, in which shall be worked a rod and piston plunger or projector, and
which shall be closed at, one end, such cylender or case having one, two, or
more tubular or other openings placed one above the other on each side of the
cylender or case opposite each other for the ingress and egress of water, each
opening to be supplied with a "shut-off," by means of which either one or
both of such openings may be closed or opened as may be required for the
purpose of backing water or otherwise, and to be worked by suitable machinery
or apparatus, the cylender or case to be supplied with one, two, or more valves for
the ingress of water, which valve or valves shall be self-acting by the pressure
