page_text: A rod or wire 11 is inserted in the end of the tube 7 inside of the annular
recess 9, and at its end it carries a valve 12 forming the valve of the syringe.
The rod is preferably bent so as to bring the valve 12 in line with the axis
of the tube.
The nozzle or end piece is preferably formed of soft rubber and consists of a
tube 13 having a contracted end provided with a bevelled or bell-shaped outer
surface 14, adapted to fit against the under surface of the valve 12 and make a
close or tight joint therewith. Formed integrally with or secured to the tube 13
is the flaring or bell-shaped shield or flange 15, preferably provided at its edge
with the bead or rib 16 which rests against the, edge of the disc 8 when the device
is in use.
The rear end of the tube 13 is inserted into the annular recess 9 and the
nozzle is secured in position by the engagement of the tube with the underside of
the valve 12, and the pressure of the liquid in the syringe tends to hold the end of
the nozzle against the valve and so keep it closed.
The operation of the device is as follows; The receptacle having been supplied
with liquid, the nozzle or end piece is inserted into the vagina or other opening
into which it is desired to inject the liquid, and slight pressure is applied to the
disc or plate 8. This presses the flange 15 against the surface of the body,
surrounding the opening into which the nozzle or end piece is inserted, and forces
its end back or away from the valve 12 and leaves the end of the tube 13 open, as
shown in Fig. 2, the walls of the tube 13 bending or wrinkling sufficiently for this
purpose. Then by compressing the receptacle the liquid will be ejected through
the opening around the valve 12 and will be thrown against the walls of the vagina
and into all the folds thereof, completely filling the vagina and opening all the
folds thereof; and upon relieving the pressure from the receptacle the liquid and
the material taken up by it will flow back into the open end of the nozzle. Upon
removing the syringe or relieving the pressure against the plate 7, the nozzle or
end piece immediately returns to its normal position, bringing its end against the
valve and thereby automatically closing the opening in the end of the nozzle
and preventing the escape of any liquid therefrom.
The syringe shown is especially adapted for use as a vaginal syringe. The user
after inserting the nozzle or end piece into the vagina, can, by applying the fingers
of one hand to the plate or disc 8, press the same towards the body, thereby
compressing the flange 15 and moving the end of the nozzle away from the
valve 12; and by compressing the receptacle with the other hand, readily inject
the liquid into the vagina, and upon relieving the pressure from the receptacle the
liquid will be drawn back into the receptacle through the open end of the nozzle.
Upon removing the syringe the end of the nozzle is instantly and automatically
closed and none of the liquid escapes therefrom. The nozzle may be readily slipped
off over the valve 12 for the purpose of cleansing it, and it may be as readily
replaced. The rod or wire upon which the valve is secured is preferably screwed
into the end of the tube 7, and by screwing the rod in or out the position of the
valve may be varied and adjusted. The valve might obviously be adjusted on
the rcd.
In the modified construction shown in Figs. 5 and 6 the receptacle 2 is preferably
made of hard rubber or metal and has the reduced extension or nozzle 13 formed
integrally or screwed to it.
A bulb 19 is connected to the receptacle 2 by a tube 20, and this tube may be
connected to a tube 21 that extends into the interior of the receptacle 2. The end
of the nozzle is provided with a valve 22 secured upon a valve stem 23 which passes
through a suitable stuffing box 24 at the rear end of the receptacle. A handle 25
is provided on the end of the valve stem, and a spring 26 is arranged between said
bandle and said stuffing box. The inner end of the stuffing box is preferably made
in spiral form, and a pin 27 in the stem 23 bears upon this spiral end of the stuffing
box. A suitable seat 28 is provided in the nozzle for the valve 22, and when said
stem is turned so as to bring the pin on the valve stem over the highest point of

A communication to me from the SHATTUCK NOVELTY COMPANY, a corporation
organized under the laws of the State of Minnesota, United States of America,
and doing business at 2125, Gerard Avenue South, in the City of Minneapolis,
County of Hennepin, in the said State, Manufacturers.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, 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, and accompanying drawing, that is to say :—
The invention relates to improvements in syringes; and the object in view is to
provide a syringe that will hold any desired liquid so as to prevent any portion
thereof from escaping when the syringe is not in use, and that may, after it has
been inserted into the part or opening into which it is desired to inject the liquid,
be opened at the end or nozzle, thereby causing its end to recede from the fixed
valve, or the valve to move from the end of the nozzle.
Another object of the invention is to provide a syringe that is especially adapted
for injecting fluids into the vagina.
In the accompanying drawing;
Figure 1 is a longitudinal section of one form of the improved syringe.
Fig. 2 is a section of the nozzle or end piece showing the end open.
Fig. 3 is a section of the nozzle or end piece taken on a plane at right angles to
that of Fig. 1.
Fig. 4 is a front view of the disc.
Figs. 5, 6, 7 and 8 show a modified construction.
In the drawings, 2 represents the receptacle of the syringe, which may be of any
suitable form and size. As here shown the receptacle is of ovoid form and is
provided at one end with an opening in which is secured a plug 3 having a threaded
opening in it to receive the screw-threaded stopper 4. The walls of the receptacle
preferably extend beyond the plug 3, as at 5, forming a funnel to facilitate the
filling of the receptacle. When the device is in use the receptacle may be held
with the stopper end down and any sediment in the liquid will naturally collect
at this end of the receptacle. The receptacle is preferably formed of soft rubber
so as to be compressible for the purpose of forcing the liquid therefrom. The
receptacle is provided with an opening preferably centrally arranged in its wall,
surrounding which is a nipple or short tube 6. This nipple is secured to a short
tube 7 preferably by being brought over the outer surface of said tube. The
tube 7 is formed of gutta-percha or hard rubber or other suitable material, and
at its forward end it is provided with a plate or disc 8 preferably formed integrally
therewith.
The walls of the tube are made thicker at the base of the disc 8, and
an annular recess 9 is formed therein, surrounding the central opening 10
of the tube. The top and bottom of the disc is preferably curved forward,
as shown in Figs. 1 and 2, while the sides are curved backward, as shown
in Fig. 3.
This form of disc or plate is considered preferable, as when used as a
vaginal syringe it conforms to the shape of the body surrounding the opening
of the vagina and against which the plate is pressed while the syringe is in use.

page_text: the spiral the valve will be closed.
When the stem is turned in the other direction.
the valve is opened by the spring 26. At the end of the nozzle in front of the
valve 22 is an opening 29, surrounding which is preferably a series of perforations
or small openings 30. A recess is preferably arranged in the nozzle between the
valve 22 and the opening 29 in which is arranged a ball 31. The ball 31 and the
perforations 30 may, however, be omitted, as shown in Fig. 7.
The operation of this form of syringe is as follows: After the nozzle is inserted
in the vagina or other opening the valve 22 is opened by turning the handle 25 and
the bulb is compressed, forcing the liquid out through the perforations 30, the
pressure of the liquid forcing the ball 31 against the opening 29 and closing the
same. Upon relieving the pressure from the bulb the liquid will flow back through
the opening 29, the ball moving away from said opening and into the receptacle.
This operation can be repeated as many times as necessary. The valve can then
be closed and the device removed without permitting the escape of any of the liquid.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is ;-
1. In a syringe, the combination, with a fixed valve, of a movable nozzle or end
piece adapted to have its eud moved to or from said valve for the purpose of
closing or opening the nozzle.
2. In a syringe, the combination, with the tube having a rigid disc or plate, of
the fixed valve and the yielding nozzle arranged between said disc and said valve.
3. In a syringe, the combination, with the tube having the rigid disc or plate and
the annular recess in its forward end, of the fixed valve, and the yielding nozzle
having its rear end inserted in said annular recess, and having a yielding flange or
shield.
4. In a syringe, the combination, of a nozzle and a valve located at and adapted
to close the end of the nozzle, and means whereby said valve and the end of the
nozzle may be separated for the purpose of opening the nozzle.
5. In a syringe, the combination, of a nozzle and a valve arranged to close said
nozzle, and means whereby upon applying pressure to a movable part of the
syringe the valve is opened, and upon relieving such pressure the valve is
automatically closed.
6. In a syringe, two meeting parts forming a tight over-lapping joint, the outer
part being rigid, and the inner part flexible and yielding and placed loosely
against the outer part and adapted to be held thereto by pressure of the liquid
within the syringe.
