page_text: We JAMES BERNARD SIMAS, of Lawrence, Massachusetts, U.S.A. Merchant,
JAMES AUGUSTINE MANSFIELD, of Danvers, Massachusetts, U.S.A., Merchant, and
JOHN SKILLING, of Lawrence, Massachusetts, U.S.A., Clerk, 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:-
Our invention relates more especially to the nozzles of syringes; and it consists
in the novel construction and arrangement of the parts hereinafter set forth the
object being to produce more effective and otherwise desirable articles of this
character than are now in ordinary use.
It is well known that in the use of syringes as usually constructed, more
especially of the class known as vaginal or female syringes, much trouble is
experienced in forcing the liquid through the nozzle, on account of the discharge
orifices in the same being closed by the contraction of the vagina or surrounding
parts, thus rendering it difficult for physicians and others to administer medicated
injections properly or in such a manner as to produce the desired results.
The present improvements are designed to obviate this objection or difficulty,
and to this end I make use of means which will be readily understood by all
conversant with such matters from the following explanation, the extreme
simplicity of the invention rendering an elaborate description unnecessary.
.
In the accompanying drawing
Figure 1 is a side elevation of our improved syringe ;
Figure 2 is a like view of the nozzle detached;
Figure 3 is a vertical longitudinal section of the nozzle;
Figure 4 is an elevation of the outer end of the guard; and
Figure 5 is a transverse section of the guard and tip of the nozzle.
Like letters of reference indicate corresponding parts in the different figures of
the drawing.
A represents the bulb, B the suction tube or induction pipe, C the discharge tube
or eduction pipe, and D the coupling, these parts being of the ordinary form and
construction.
A detachable nozzle E, preferably composed of metal and having a tip f, is
screwed into the coupling D, as shown at x, said nozzle being constructed of any
suitable size or length and provided with a series of holes or discharge orifices m.
The body of the nozzle is enlarged to form the annular shoulder z; and forward
of said shoulder it is exteriorly screw-threaded to receive a guard H.
The guard consists of a series of metallic wires 7, arranged approximately at
equal distances apart and in parallelism with the tip f, the rear ends of said wires
being secured in a ring J, and the forward ends curved inwardly or converged and
secured to a ring K, which is disposed a short distance in front of the tip f
The ring J is interiorly screw-threaded; and, in attaching the guard to the
nozzle, said ring is screwed onto the body E, as shown at v.
D

page_text: The ring K is provided with a hole r, through which the liquid discharged from
the extreme end of the tip f may pass.
The object of the guard is to keep the vagina or surrounding parts distended or
out of contact with the tip f, thereby preventing the holes or orifices m from being
closed, and permitting the injection to be freely administered in a manner which
will be readily obvious without a more explicit description.
The use of the guard is not confined to vaginal or female syringes only, as guards
constructed on the same general principle are well adapted for use with other
classes of syringes. Neither do we confine ourselves to attaching the guard to the
body of the nozzle E, as the parts may be so constructed that it may be readily
secured to the coupling D, if desired; nor to providing the tip f with any special
number or kind of discharge orifices m, as the number and arrangement of these
may be varied as required; nor to providing the body E with the shoulder z, or
constructing the ring K with the hole r.
Instead of the wires a foraminous tube having a series of elongated slots and
provided with a suitable tip or terminal point at its outer end may be employed.
A tube composed of wire netting or wire cloth having meshes through which the
liquid may pass and provided with a suitable tip at its outer end may also be used,
instead of a guard comprised of wires arranged, as shown, the object being to
furnish an open-work guard which will keep the parts from closing the orifices in
the nozzle and through which the liquid or injection may be passed with the least
possible obstruction.
It will be obvious that the guard may be readily detached and the nozzle used
in the same manner as in ordinary syringes, whenever desired.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is -
First. In a syringe, a guard disposed around the nozzle and adapted to keep the
vagina or surrounding parts distended and out of contact with the discharge
orifices of the nozzle, said guard being adapted to permit the liquid or injection to
be thrown or discharged through the same against the surrounding parts in
administering the injection, substantially as described.
Second. In a syringe, the nozzle E provided with the guard H combined and
arranged to operate substantially as set forth.
Third. In a syringe, the nozzle E provided with the screw-thread v, in com-
bination with the guard H adapted to be attached to said nozzle by the threaded
ring J, substantially as described..
Fourth. In a syringe, the guard H consisting of the wires and rings K, J, said
guard being adapted to receive the nozzle and keep its tip out of contact with the
vagina or surrounding parts, substantially as set forth.
Fifth. In a syringe, the nozzle E and guard H, constructed, combined and
arranged to operate substantially as described.
Sixth. In a syringe, a discharge nozzle provided with a detachable wire or open
work guard, substantially.as set forth.
