PROVISIONAL SPECIFICATION.
Improvements in or applicable to Syringes.
I, JAMES HENRY STONE trading as Benton & Stone, Bracebridge Street,
Birmingham, Manufacturer, do hereby declare the nature of my said invention
to be as follows:-
My improvements refer to attachments for the rose and jet and similar loose parts
of syringes and consists in dispensing with the usual side pieces or mounts on the
barrel which are very liable to be broken off by falls or other accidents, and
providing special mounts for these parts on the rod of the syringe immediately
below the handle or on the cap of the syringe through which the piston rod works
so that they shall be more within the line of the syringe and so be less exposed to
rough usage.
The method now in use of affixing one or more side pieces or mounts on the
syringe barrel on to which these before mentioned parts are screwed is inconvenient
in that it affects the proper balancing of the syringe and interferes with its con-
venient handling, whereas by my improvements the parts are securely attached to
the syringe rod and are free from the objectionable features before mentioned.
Dated this 9th day of December 1892.

COMPLETE SPECIFICATION.
Improvements in or applicable to Syringes.
I, JAMES HENRY STONE, trading as Benton & Stone, Bracebridge Street,
Birmingham, Manufacturer, do hereby declare the nature of my said invention.
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My improvements refer to attachments for the rose and jet and similar loose parts
of syringes and consists in dispensing with the usual side pieces or mouths on the
barrel which are very liable to be broken off by falls or other accidents and
providing special mounts for these parts on the rod of the syringe immediately
below the handle or on the cap of the syringe through which the piston rod works
so that they shall be more within the line of the syringe and so be less exposed to
rough usage.
On the accompanying drawing
Fig. 1 illustrates a garden syringe with the mounts as applied to the piston rod
shewn in elevation and
Fig. 2 illustrates the same syringe with the mounts as applied to the piston rod
shewn in plan.
Fig. 3 is an enlarged section on line a-b (see Fig. 2) shewing more clearly the
application of the mounts to the piston rod.
Fig. 4 illustrates the mounts as applied to the cap of the syringe.
A is the barrel of the syringe and B the piston rod. Onto the rod B near the
handle C is fitted the mounts D D arranged back to back and made by preference
in one piece as illustrated. Said mounts are each provided with a screw thread as
illustrated which corresponds to the thread of the rose or jet.
The mounts are
either secured direct to the piston rod by any suitable means or they are
attached to or form part of the central sleeve E which is rigidly fitted on to the
rod B.

page_text: A single mount may be fixed on the piston rod but to ensure of the proper
balancing of the piston rod two are preferred. Three or more mounts may be fixed
on the rod if desired.
In lieu of fitting the mounts on to the piston rod they may be fitted on to or form
part of the barrel cap E through which the piston rod works as illustrated in Fig. 4,
in this case the rod being rendered lighter in use.
The method now in use of affixing one or more side pieces or mounts on the
syringe barrel on to which the rose and jet parts are screwed is inconvenient in that
it affects the proper balancing of the syringe and interferes with its convenient
handling, whereas by my improvements the parts are securely attached to the
syringe rod and are free from the objectionable features before-mentioned.
In soldering the mounts to the barrel as heretofore it has been found that the
barrel becomes distorted owing to the heat, hence my invention possesses a further
advantage in avoiding this objectionable effect.
Having thus 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 :-
1st. In syringes and the like the use of one or more mounts fitted to the piston
rod for holding the rose, jet or other parts substantially as set forth.
2nd. In syringes and the like the use of one or more mounts fitted to or forming
part of the syringe cap for holding the rose, jet or other parts substantially as set
forth.
