PROVISIONAL SPECIFICATION left by the said Frank Kingston at the
Office of the Commissioners of Patents on the 23rd March 1882.
FRANK KINGSTON, Engineer, of 87, Albin Road, St. Johns, in the County of
Kent, "AN IMPROVED INSTRUMENT TO FACILITATE THE ADMINISTRATION OF
FLUIDS TO THE STOMACH"
My invention is specially of value where medicine or liquid food is to be given
to young children or invalids where there is often difficulty in getting them to
accept the same.
In this invention a chamber made of suitable material is employed to contain
the fluid to be administered. This chamber is furnished with an opening in or
near the top through which it can be supplied with the required quantity of the
fluid, and a discharge passage or spout of some length and small box which springs
from the said chamber-Attached to the upper part of the chamber is an elastic air
vessel the interior of which is in communication with the interior of the chamber
for containing the fluid.
The mode of operation is as follows: The Chamber having been supplied with
the fluid the discharge passage or spout is introduced into the mouth of the person
to whom the fluid is to be administered above, and at the back of the tongue.
While the operator keeps a finger pressed on the opening in the top of the chamber
no fluid will escape but on raising his finger it flows in quantities as desired.
Where the fluid is thick the elastic air vessel is compressed in order to produce
pressure of air on the surface of the fluid the opening in the top of the chamber
being meanwhile kept closed.
In this manner I gain complete control over the discharge of the fluid in
administering it.

FLUIDS TO THE STOMACH
"
INSTRUMENT TO FACILITATE THE
ADMINISTRATION OF
My Invention relates to an instrument for facilitating the administration of
fluids, such instrument being particularly applicable where medicine or liquid food
is to be given to young children or invalids where there is often difficulty in getting
them to accept the same.
The instrument consists of a chamber to contain the fluid to be administered.
This chamber has an opening at or near the top through which it can be supplied
with the required quantity of the fluid, and it has a discharge passage or spout of
some length and small bore. To the upper part of the chamber is attached.an
elastic air vessel communicating with the chamber. The mode of operation is as
follows. The chamber having been supplied with the fluid the discharge passage
or spout is introduced into the mouth of the person to whom the fluid is to be
administered, above, and at the back of the tongue. While the operator keeps a
finger pressed on the opening in the top of the chamber no fluid issues but when
he raises his finger it flows in quantities as desired. When the fluid is thick the
top orifice is kept closed and the elastic air vessel is compressed producing pressure
on the surface of the fluid which causes it to issue by the spout. Thus in
administrating the fluid there is complete control over its discharge.
The instrument may be inade in various forms some of which are represented by
the accompanying drawings. Fig. 1 is a section and Fig. 2 a plan of one form, in
which A is the chamber graduated if desired, B the discharge passage or spout, C
the top opening for charging the vessel and Da caoutchouc ball constituting the
elastic air vessel communicating with the chamber, so that on closing the opening C
by a finger and compressing by the thumb the ball D the fluid in the chamber A
can be subjected to pressure when required. The instrument may be made of
glass or ceramic material in which case it is preferred to enclose the spout B in an
india-rubber or metal sheath. A projection E from the front of the instrument
prevents its insertion too far into the mouth and also gives a hold for some of the
fingers while a finger and thumb are applied at C and D. Figs. 3 and 4 shew a
modified form in which the elastic air vessel D is attached to a hinged lid which
covers the opening C. In another form shewn by the longitudinal section Fig. 5,
the end view Fig. 5ª and the plan Fig. 6 the projection E and a corresponding
projection F serve as feet for the instrument. Instead of employing a caoutchouc
ball to give the pressure a piston or plunger may be employed as shown in Figs. 7
In this case
and 8 which are sections on planes at right angles to one another.
the chamber A is of tubular form fitted with a piston or plunger G, which being
pressed inwards by the fingers, forces the fluid out at the spout B.
Having thus described the nature of my invention and in what manner the same
is to be performed, I claim:
The use of an instrument to facilitate the administration of fluids to the stomach,
the said instrument being constructed and operating substantially as herein described
with reference to the accompanying drawings.
In witness whereof I the said Frank Kingston have hereunto set my hand
and seal this Nineteenth day of September in the year of our Lord One
thousand eight hundred and eighty two.
FRANK KINGSTON.
