page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANDREW
PAUL, of Doughty Street, in the Parish of Saint Pancras, and County of
Middlesex, Surgeon, A.B., and M.B., send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Thirtieth day of July, in the second year of Her reign, and
in the year of our Lord One thousand eight hundred and thirty-eight, did, for
Herself, Her heirs and successors, give and grant unto me, the said Andrew
Paul, Her especial licence, full power, sole privilege, and authority, that I,
the said Andrew Paul, my executors, administrators, and assigns, or such
others as I, the said Andrew Paul, my executors, administrators, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein mentioned, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, and also in all Her Majesty's Colonies and Plantations
abroad, my Invention of "AN IMPROVED HYDRAULIC PUMP, DOUCHE, OR JET D'EAU,
APPLICABLE TO ALL THE PURPOSES OF LAVEMENT IN MEDICAL OPERATIONS;" in
which said Letters Patent is contained a proviso obliging, me, the said
Andrew Paul, by an instrument in writing under my hand and seal, particu-
larly to describe and ascertain the nature of my said Invention, and in what

page_text: manner the same is to be performed, and to cause the same to be enrolled in
Her Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in and
by the same, reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso contained in
the said recited Letters Patent, I, the said Andrew Paul, do hereby declare
that the nature of my said Invention, and the manner in which the same is
to be performed, are particularly described and ascertained in and by the
following description thereof, reference being had to the Drawings hereunto
annexed, and to the letters and figures marked thereon (that is to say):-
My Invention of an improved hydraulic pump, douché, or jet d'eau,
applicable to all the purposes of lavement in medical operations, consist in
the arrangement of a convenient and compact apparatus for the bedchamber,
in which all the parts and implements required to be used for the purposes of
medical lavement are enclosed in a portable chest, capable of being locked up
and removed from room to room, or for travelling. The construction of this
apparatus is shewn in the accompanying Drawings, in which Fig. 1, is a top
view of the apparatus, the lid of the chest being thrown open; Fig. 2, is a
front view of the same, the front of the chest being removed, & the pan
shewn in section, for the purpose of shewing the internal arrangement of the
operating parts of the apparatus; Fig. 3 is a side view of the chest, the
moveable end being slidden out, in order to exhibit the pump and its appen-
dages; and. Fig. 4. is a section taken transversely through the chest, and
through the middle of the pan, similar letters of reference' pointing out similar
parts in all the Figures. The chest is an oblong square box a, a, a, the lid of
which b, rises on hinges with quadrant guides c, c. .The end d of the box slides
in grooves, and is capable of being removed, as in Fig. 3, for the purpose of
gaining ready access to the pump when required. The seat e is moveable as
in ordinary, night chairs. It covers the mouth of a pan f, which is to be
constructed of thin metal. The top or ledge of the pan is supported in a
horizontal partition g, g, and against the side of a vertical partition h; the pump
i, is attached, which is of the ordinary construction, of lift pumps; k is the
.handle or lever, for working the piston of the pump.
When the apparatus is
in action the pan must contain about a gallon of water either pure or impreg-
nated with medicinal matters, and the water may be warm or cold as the
circumstances of the patient may require.. A pipe leads from an aperture in
.the bottom of the pan to the under part of the barrel of the pump, by which
the water is supplied to the pump; m, is a pipe connected to the top of the

page_text: pump barrel, which pipe leads to the aperture n of the jet in the centre of
the pan. The jet tubes o, may be of very different constructions either to
project the water upwards in a shower, or to conduct it through a tube in a
stream. Several different descriptions of jet tubes are appended to the appa.
ratus, some of which have flat perforated rose heads for the purpose of
directing a shower with any required degree of intensity against the part
affected, other jet tubes have open, ends for conducting the water through a
bent tube or flexible pipe into the bowels, as lavement, if necessary, These jet
tubes may be conveniently suspended in the angles of the horizontal partition,
and whichever of them may be required to be brought into use must be
screwed into the central aperture n in the bottom of the pan. The pan being
charged as described with a suitable quantity of water either pure or medically
impregnated, the patient when sitting upon the seat immediately over the
orifice of the jet, works the pump with any degree of rapidity that may be
required to give greater or less force to the jet, which will cause the water to
be forced up through the jet either in a shower or a stream according to the
construction of the jet, and the operation may be continued for any length of
time desired, as the water on descending passes by the open orifice p through
the pipe to the pump to be thrown up again, and so on continually as long
as the pump is kept in action. When the operation of lavement is done, the
water may be drawn off from the pan through a bent tube to be attached to
the orifice n in the centre of the pan, by working the pump till the water is
expelled. But I would observe that it is desirable to leave a small quantity
of water in the pump barrel, in order to prevent the packing of the piston
becoming dry and hard. Plugs may be screwed into the orifices n and p, in
the bottom of the pan, to close them when the pump is not in use, and then
the pan may be employed as a foot bath. I have said that four different sorts
of jet tubes may be packed in the apparatus by letting them drop into holes
in the angles of the horizontal partition. The bent tube and flexible tube
when out of use may be also held by buttons and loops attached to the inner
part of the sliding end piece d, and the vacant space under the pan may have
a drawer for towels and other articles.
In witness whereof, I the said Andrew Paul, have hercunto set my
hand and seal, this Thirtieth day of January, in the year of our Lord
One thousand eight hundred and thirty-nine.
ANDREW (L.S.) PAUL.
