Complete Specification Left, 4th Nov., 1896-Accepted, 13th Feb., 1897
JOSIAH KEIGHLEY Draper Melrose Highweek Newton Abbot South Devon do
hereby declare the nature of this invention to be as follows:-
One or more openings on the side, near the bottom of the syringe. Covered by a
shutter, slide, lifter or valve, which can be opened and closed from a position near
the top of syringe, by the horizontal or perpendicular movement of a tube or rod
attachment, by hand or spring.
The whole of the fittings are attached to the outside of barrel of syringe, by
clamps, grips, or solder.
The objects of the above attachments to ordinary syringe, are for the, easier and
quicker filling.

I JOSIAH KEIGHLEY Draper Melrose Highweek Newton Abbot South Devon 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 :-
This improvement relates to a simple arrangement of parts, by which less energy
is required to actuate the piston of a syringe, and less time is taken to charge
same.
The arrangement will be best understood by reference to the accompanying
drawings.
Figure 1 represents a front, and
Figure 2 a side view of syringe.
Figure 3 is a section on a larger scale, of the top and bottom parts of syringe.
Figure 4 is a section of one side of same at bottom end.
Figure 5 is a section through line a-b.
Figure 6 is a section through line c-d.
A is the barrel of syringe, in which attached to the piston rod B' works. the
piston B. C is a sliding valve or shutter covering one or more openings D, in the
side and near to the bottom of the barrel A. The valve C is kept in position by, and
slides in grooves formed by attaching guide pieces C¹ by solder or other means to side
of barrel. To valve C is attached a hollow rod G which has a finger hook F formed
near to its upper end, and a small hole or opening G' at its lower end. The top end
of rod presses by ring H against a spiral spring I, kept in position by spring case J
and perforated collar J₁ formed in same. At the top of the spring case J is a small
ונס.D

page_text: chamber which has an opening K in the side, connected to a corresponding opening
in the side of barrel A. The rod G is guided and kept in position by sleeves or
guides E, as well as by the spring case J, all attached to barrel by solder or other
means.
The action of this my improved syringe, may be described as follows.
On charging the syringe, the sliding valve is first moved from the closed position
as shown on Fig. 3, to the open position as shown on Fig. 4 by the finger catching
the hook F on hollow rod G and pulling rod up against the spiral spring I. When
the piston has been withdrawn, and the barrel thereby charged through the inlet D
in conjunction with the opening or openings in the nozzle, the hook F is released and
valve sluts by action of compressed spring pressing against end of rod, or, I may
dispense with the spring and close the valve by hand, the contents are then discharged
through the nozzle, in the ordinary way.
Any leakage that may have passed the piston while discharging, drains back
through the hole K in the top of barrel, thence down spring case J and hollow rod G
to the opening. G' in the bottom of rod, into receptacle from which, and while it is
being recharged.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The general arrangement and construction of syringe substantially as herein-
before described.
2. The mode and apparatus for providing the means of charging syringe as
bereinbefore described and illustrated.
.3. The mode of, and apparatus for providing the means by which leakage is
conveyed back into the receptacle as hereinbefore described and illustrated.
Dated this 3rd day of November 1896.
