PROVISIONAL SPECIFICATION.
Improvements in Syringes for Injecting Morphia, and for like
purposes.
1, WILLIAM EVARTS RICHARDS, of 203 Broadway, New York, United States
of America, Patent Solicitor, do hereby declare the nature of this invention to be
as follows:-
:-
My invention relates to an improved arrangement and construction of a syringe
whereby I am enabled to protect the needle and to carry the injection solution
within the same case, and to make one self-contained pocket instrument which can
be conveniently opened and closed and is always ready for use.
In carrying my invention into effect I construct in any usual ordinary manner,
the syringe or main suction and delivery portion of the instrument, and I provide
a scale upon the barrel for indicating the amount of solution to be injected as at
present employed on ordinary instruments but upon the outer end of the case or
barrel of the syringe I provide a screw nipple or thread to receive a cap or small
barrel-like cylinder which protects and encloses another small cylinder or bottle
into which the injection needle enters through a stopper, plug or cock of india-
rubber or other suitable elastic material, the needle being always immersed in the
solution which is to be injected.
Instead of having a separate independent injection fluid case 1 sometimes make
my enclosing chamber to simply protect the needle, and upon the other end main.
barrel I have a similar cap or enclosing case into which I introduce the injection
bottle or vial containing the fluid having any ordinary stopper or cork.
When arranging my injecting needle to be always immersed in the fluid I
make it to pass through a hole in the stopper or plug of elastic material in such a
manner that the material closes upon the needle and keeps it clean, which yet
permits of its being withdrawn when the syringe is to be used in the ordinary
manner. The cap I make to be adjustable by means of a fine thread or by any.
other tight fitting device at present employed for carrying cases or covers upon
instruments such as stylographic pens and the like.
The opposite end or handle end of the barrel I cover with a cap which keeps
the barrel perfectly clean and thus ensuring that no dirt or foreign matter shall
find access thereto, the cap being removed when the instrument is to be used.
I modify the form of my tube which is to serve as the protecting case, and the
manner of carrying the vial of injection fluid, sometimes employing a case with a
flange on the outer end to withdraw the vial, and sometimes making the vial to
rest upon the plug or stopper and form a joint the end of the plug or stopper being
held by a ring or flange-like projection, formed within the main casing.
I do not limit the application of my invention to any particular form of syringe
or to any particular arrangement of casing, but I make the shape and con-
figuration of the casing and the manner of covering the syringe handle and
carrying the vial to suit the size and form of instrument which it is desired to
construct.

purposes.
I, WILLIAM EVARTS RICHARDS, of 203 Broadway New York, United States
of America, Patent Solicitor, 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:-
My invention has for its object; First, to so construct the syringe that it will
be self-contained i.e. so that all the parts may be self enclosed, and without
employing a separate box as is now usually done; second, to protect both the
needle and the piston end of the syringe from injury and from dust and dirt;
third, to provide receptacles for carrying injection solutions, tablets, extra needles
or cleaning wires, as desired, and to locate such receptacles within the same
containing case as the needle and the other parts of the syringe; fourth, to
provide means whereby the needle may, if desired, be carried in the vial containing
the injection fluid, so as to economize space, keep the parts assembled, and ready
for instant use at any time. Fifth, to so construct the syringe that it may be
carried in the pocket like a pencil or pen.
In the drawings which illustrate my invention, and which form a part of this
specification, I show several forms in which my invention may be embodied.
Figure 1 is a central, longitudinal section showing a syringe with the needle and
piston ends enclosed and protected by caps or cylinders.
Figure 2 is a central longitudinal section showing a syringe having its piston
end enclosed by a cap, and its needle end by a cap or cylinder which also contains.
a vial of injecting fluid.
Figure 3 is a central vertical section of the stopper for the vial of injecting
solution.
Figure 4 is a central sectional view of the needle end a syringe of modified
construction one end being broken away.
Figure 5 is a central longitudinal section showing a syringe having a cylinder
with a vial of injecting fluid at the needle end, and a cylinder with a vial
containing extra needles at the piston end.
The body portion A of the syringe may be constructed in any usual or desired
way. As shown, it consists of a metal case A', cut partially away upon one side a
containing a glass tube A2 which is provided with a graduated scale for indicating
minims and or other degrees of measurement. The syringe is provided with the
usual needle E and piston A³, and is closed at each end with screw-caps a² a³,
provided with washers or packing to prevent leakage. The glass tube A² is
arranged within the case A so that the side of the tube provided with the scale
passes up through the cut away part a, and is thereby exposed to view.
At each end of the body portion A I provide screw nipples B B₁ preferably
integral with the screw caps a² a3 adapted to receive a cap or barrel-like cylinder
which encloses and protects the needle and piston ends.
Thus the cylinder C is provided with an interior screw thread for engagement
with the screw-nipple B, and encloses the end of the piston A³, protecting it from
injury, and preventing the entrance of dust and dirt into the body portion A
through that end of the syringe, whilst the cylinder D, also provided with an
interior screw thread, engages with the screw nipple B¹ and encloses the needle
eud, protecting the needle from injury, and preventing it from becoming foul, and
also preventing the entrance of dust and dirt into the body portion A from that
end of the syringe. The last named features are important, for should the needle

page_text: become foul or dirty, or dust or dirt be injected under the skin of a patient, an
abscess will almost certainly result and much suffering and annoyance caused
thereby. Either one or both of the cylinders CD may be constructed of a
sufficient length to receive and contain a vial F of injecting solution, or one
cylinder may contain a vial F of solution, and the other may contain a vial of
hypodermic tablets, or extra needles, or cleaning wires. If the vial F is contained
in the cylinder D at the needle end of the syringe I prefer to employ a stopper Fl
which is provided with a central aperture f. In practice, when the cylinder D is
to be screwed upon the nipple B¹, the needle E is first passed through the
aperture of the stopper F', and down inside the vial F., and then the cylinder is
screwed on the nipple. This construction and operation serves several purposes-
First, in the act of passing the needle through the stopper the needle is wiped and
cleaned; second, space is economised; third, the needle is carried immersed in.
the injecting solution ready for instant use.
In order to give an injection it is only necessary to unscrew the cylinder C from.
the piston end, and to draw out the piston the required distance to draw up the
desired quantity of the injecting solution from the vial F into the body A of the
syringe, the quantity will be measured as the solution is drawn into the body A,
by the minim or other indicated scale upon the glass tube A2. When the desired
quantity of solution is in the syringe, the cylinder D is unscrewed from the needle
end, the needle E is withdrawn from the vial F through the stopper F¹, and the
syringe is ready for use, and the injection may be given; when this is done, the
parts are again assembled by passing the needle E through the aperture f of
the stopper Finto the vial F, and the cylinders at either end are screwed into place
upon the screw nipples B B', or if preferred the vial F may be filled with an
antiseptic solution, and the needles when not in use, be carried immersed in this
solution.
It will thus be seen that not only is my syringe self-contained, and in shape as.
convenient to carry in the pocket as a pencil or pen, but that it may also be '
carried with all the parts assembled together and ready for instant use. No
separate box is required, and no time is lost in assembling the syringe as has
heretofore been the fact. Moreover, the injecting solution is always at hand, is
carried and contained in the same case as the syringe, and a full supply of
hypodermic tablets, extra needles and cleaning wires may also be carried in this
case without employing separate boxes, bottles and the like receptacles for them.
as is now usual.
The cylinder D, as shown in Figure 4, is provided with interior screw-threads
at one end, a screw cap D' provided with interior screw-threads is adapted to close
the cylinder at its outer end. A flange or ring like projection d is formed in the
interior of the cylinder D, at such a point relative to its length that when the
vial F is placed within the cylinder, and the cylinder is screwed on the screw-
nipple B1 the stopper F1 will abut against the flange d and the vial will be
held tightly in place. The cylinder C also, as shown in Figure 5 may be
provided with a flange c for the vial G to rest upon, and may be interiorly
screw-threaded and be closed at its outer end by a screw cap C¹.
In Figure 1 I have shown a syringe having simple cylinders C D for enclosing
the needle and piston ends. When constructing in this way the injecting solutions
etc. must be carried separately. If desired, the vials F, may be dispensed with,
and the cylinders C D adapted to receive and contain the tablets, needles etc.
directly. lustead of constructing the syringe and other parts of metal, hard
rubber, celluloid, or any other similar substance may be used. In such case it will
not be necessary to screw-thread the nipples B B of the cylinders C D as these
parts may be held together by frictional contact, and may be suitably constructed
to accomplish this object.
Although I have shown and described my invention with particular reference-
to hypodermic syringes, I do not limit myself to its use to any specific form
of instrument.
