PROVISIONAL SPECIFICATION left by the said George Nye at the
Office of the Commissioners of Patents, with his Petition, on the 26th
August 1861.
I, GEORGE NYE, of No. 18, Mount Street, Lambeth, in the County of Surrey,
Surgical Instrument Maker, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN APPARATUS FOR ADMINISTERING INJECTION IN A
CONTINUOUS STREAM, ALSO APPLICABLE AS AN EYE DOUCHE AND OTHER PURPOSES,"
to be as follows:-
This Invention has for its object the obtaining a continuous stream of water
or other fluid and consists of a metallic reservoir of convenient size to contain
the fluid to be used, and is furnished with an injection tube and stop-cock,
which tube turns upon a joint for the purpose of regulating its position and
convenience for use; upon the top of the reservoir is affixed a vulcanized
india-rubber bottle or ball fitted with air valves. By compressing the bottle
or ball air is forced into the reservoir and the fluid is thereby projected in a

page_text: continuous stream. By another arrangement I produce the same effect. This
consists of a metallic air vessel enclosing tho induction pipe to which is attached
a valve, and at the bottom of the air vessel is a foot also containing
valve;
at the top of the air vessel is affixed a vulcanized india-rubber bottle or ball,
by the alternate compression and expansion of which the water or other fluid
is forced into the air vessel and thence through the induction pipe in a con-
tinuous stream.
SPECIFICATION in pursuance of the conditions of the Letters Patent, file
by the said George Nyc in the Great Seal Patent Office on the 26th
February 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
NYE, of No. 18, Mount Street, Lambeth, in the County of Surrey, Surgical
Instrument Maker, send greeting.
WHEREAS Iler most Excellent Majesty Queen Victoria, by Iler Letters
Patent, bearing date the Twenty-sixth day of August, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Ilerself, ITer heirs and successors, give and grant unto me, the
said George Nye, Her special licence that I, the said Georgo Nye, my
executors, administrators, and assigns, or such others as I, the said George
Nye, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR
ADMINISTERING INJECTION IN A CONTINUOUS STREAM, AI60 APPLICABLE AS AN EYE
DOUCHE AND OTHER PURPOSES," upon the condition (amongst others) that I, the
said George Nye, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particu-
larly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Nye, do hereby declaro the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: statement thercof, reference being had to the accompanying Drawings, and
to the letters and figures marked thereon, that is to say :-
The object of this Invention is the construction of apparatus for adminis-
tering injections in a continuous stream, applicable also to eye douche
apparatus and for other like purposes.
My Invention relates to two arrangements of apparatus. The first of
these arrangements consists of an apparatus in which a vulcanized india-rubber
vessel fitted with air valves is affixed at the top of a reservoir intended to contain
the water or other fluid to be used, so that by compressing the said india-rubber
vessel air is forced into the reservoir and the water or fluid thereby projected
from it in a continuous stream. The reservoir may sometines be furnished
with an injection tube fitted with stop-cock and working on a joint.
In my second arrangement of apparatus a metallic air vessel is employed
enclosing an induction pipe in which is a chamber fitted with a valve for opening
and closing the eduction way; at the bottom of the air vessel is secured a foot
also fitted with a valve, and at the top of the air vessel is affixed a vulcanized
india-rubber vessel, by the alternate compression and expansion (or recoil) of
which, water or other fluid is forced into the air vessel and thence projected
through the outlet pipe in a continuous stream. The valve that opens and
closes the eduction way, is so arranged that it may be readily attained, removed,
and replaced.
The accompanying Drawings represent apparatus constructed according to
my Invention.
Figure 1 is a side elevation, and Figure 2 a vertical section of an injection
apparatus constructed according to my first arrangement.
A is the "reservoir" which contains the water or other liquid to be injected
which is admitted through an opening B, kept tightly closed by a screw cap or
stopper C, while the operation of injection is proceeding; D is the injection
pipe leading from the reservoir A, and E its stop-cock, the pipe turns on a
joint at F to adjust or accommodate it to the patient's convenience, as is usual;
G is a bottle, ball, or vessel of vulcanized india-rubber secured to the top of
the reservoir A by the metal screw mount a; b, c, are air valves, of which bis
fitted at the upper, and c at the lower end of the vessel G; the valve 6 shewn
apart in Figure 3 is made in two parts d and h screwing together; d is a
hollow screw open at bottom and closed at top by a head e which is recessed
on its periphery to form a groove in which are small perforations g for the
entry of air which passes through them into the shank d and through the
passage in h and perforations in a shield k into the vessel G. The best mode

page_text: of fitting these valves in place (but which mode may be varied) is thus :-I
form an opening at the top of the vessel G, and another opening opposite it at the
bottom, and the shank d is fitted at the top opening, and the part h (having an
oil silk diaphragm i at bottom) is inserted through the lower opening and brought
up to the top opening and screwed on to the part d. The lower valve c, is
screwed into the mount a which is screwed on the reservoir A; k is a metal
cap or shield for protecting the valve b from injury or displacement when the
vessel is compressed. When the vessel G is in its normal or non-compressed
state, the air enters into it through the valve b, and on compressing the vessel G
the air is forced from it through the valve cand into the reservoir A through an
orifice formed in the top of the reservoir opposite the opening of the valve c.
Thus on compressing the vessel G and allowing it to expand (or return)
to its original form alternately the fluid will be forced from the reservoir A in
a continuous stream through the injection pipe D supposing the stop-cock E
open. The form of the valves b, c, may be varied, but I prefer those shewn.
Figure 4 is an elevation showing the same or first arrangement adapted as
an eye douche.
A is a glass reservoir, closed at top by a metal cover H. The
parts G, b, c, a, are respectively similar to those indicated by like letters in
Figures 1, 2, and 3; I is a rigid pipe, preferably of metal, through which the
liquid is forced from the reservoir into the patient's eye. This pipe opens at
one end into the reservoir A to which it is secured, and at the other end it
terminates in a rose spreader, or other convenient mouth within a glass or
other cup J, to which cup the eye is applied; K is a waste pipe, leading from
the cup J. The combination of a cup J with a pipe is well known as applied
to an eye douche, but heretofore the pipe has been flexible, and the patient
has had to hold the cup and pipe to his eye with one hand while pumping
into the pipe with the other, whereas in my arrangement the pipe being rigid
and a fixture to the fluid reservoir presents itself in the required position, and
the patient can place bis eye against the cup, and is relieved from the trouble
and annoyance of holding the pipe. This arrangement may be applied as an
ear douche. In this my first arrangement of apparatus the india-rubber vessel
being fitted, as shewn, the air valves are out of reach of the liquid and pro-
tected from injury therefrom.
Figure 5 is an elevation, and Figure 6 a vertical section of an injection
apparatus, constructed according to my second arrangement. L is a metal air
vessel; M is a bottle, ball, or vessel of vulcanized india-rubber secured by a
metal mount m to the vessel L; N is the induction pipe, fixed in the chamber
or vessel L; it communicates at one end with the interior of the vessel M,

page_text: and at the other with the passage through the foot O. O is a foot,
screwed to the vessel L; it is formed tubular, or has a passage o through
it open at bottom and communicating at top with the pipe N; P is a
ball valve in the passage o; R is a ball valve for opening and closing
the eduction way.
This valve, which, with its seat, is shewn apart in
Figure 7, is fitted in a chamber Q, fixed within the pipe N, and the valve
rests on a seat S screwed to the chamber Q, and having a passage s
through it, which constitutes the thoroughfare between the valve chamber Q
and the passage o, when the valve R is raised, the valve chamber Q being
open at bottom. T is a pipe, fixed transversely to the chamber Q, in which it
opens at one end, and passing through the side of the chamber Q, and of the
pipe N opens at its other end in the chamber L; U is the outlet pipe, for
conveying the fluid from the chamber L into the person of the user or else-
where, as required. When the apparatus is to be used the bottom of the foot O
is inserted into the fluid to be injected; and the ball or vessel M having been
first compressed, and then allowed to expand back again, a vacuum will be pro-
duced in the pipe N, through which pipe the fluid will rise into the vessel M,
and on again compressing the latter the fluid will be forced back through the
pipe N, lift the valve R, and pass through the chamber Q, and pipe T into
the vessel L, and thence through and out of the pipe U. By repeating the
compression and releasing of the vessel M, the vessel L will be alternately
filled with and emptied of liquid, which will be discharged through U in a
continuous stream.
Apparatus working according to this method of action have already been
constructed and known, but in such apparatus the valve that opened and
closed the eduction way has been so fixed that it could not be reached and
removed without taking the whole apparatus to pieces, whereas in my appa-
ratus the valve R can easily be attained, removed, and replaced by unscrewing
and detaching the foot O, whereby the valve seat S will be exposed, and can
easily be attained and unscrewed to allow the valve R to be removed, and the
apparatus to be purified.
Having now described the nature of my said Invention and in what manner
the same may be performed, I declare that what I claim is as follows:-
First, in respect of my first arrangement of apparatus I claim the employ-
ment of an india-rubber compressible vessel, fitted with air valves in combi-
nation with a reservoir or holder for liquid, as herein-before described, so that
by means of such india-rubber vessel the liquid may be discharged in a
continuous stream.

page_text: Second, I claim tho application to eye and car douche apparatus of a rigid
discharge pipe fixed to a reservoir or holder of liquid, as herein-before described,
whereby the necessity of holding a pipe to the part affected is dispensed with.
Third, in respect of my second arrangement of apparatus, I claim the
arranging of the valve that opens and closes the eduction way, so that it may
bo readily removed and replaced, as herein-before described.
In witness whereof, I, the said George Nye, have hereunto set my hand
and seal, this Twenty-fifth day of February, in the year of our Lord
One thousand eight hundred and sixty-two.
