I, ROBERT TOLLADAY Foreman Brassfinisher of No. 8, Chandos Road Highgate'
Park Birmingham in the County of Warwick, do hereby declare the nature of this
invention to be as follows:-
This compound rose is constructed with a tube attached to the cap and of a smaller
size than the cap which is perforated with a ring of large holes near to the cap the
has also a circle of small holes on its face outside of the tube above described
and a large hole in the centre with a collar for the sliding valve to work against.
cap
The sliding valve is another tube accurately fitting into the tube above described
one end being enclosed and perforated with small holes all over so that it forms a part
of the rose when the pressure is applied to force the fluid out.
The large holes in the tube attached to the cap allow the syringe to be instantly
filled when the suction stroke is commenced and, when the pressure is put on to
force out the fluid the sliding valve covers the ring of large holes and makes it
perfectly air tight.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of a Compound Rose and Sliding
Valve to be Used in Conjunction with an Ordinary Syringe or
other similar Article.
I ROBERT TOLLADAY Foreman Brassfinisher of No. 8, Chandos Road Highgate
Park Birmingham in the County of Warwick, 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 relates to an improved method in the manufacture of a compound
rose and sliding valve to be used in conjunction with an ordinary syringe or other
similar article.
This and a slight modification of the same comprises the improvements hereinafter
described.
This compound rose is constructed with a tube attached to the cap which is
perforated with a ring of large holes near to the cap but the tube is of a smaller size
than the cap.
The cap has also circles of small holes on its face outside of the tube above described
and a large hole in the centre with a collar for the sliding valve or bucket to work
against.
The sliding valve is another tube accurately fitting into the tube above described
one end being enclosed and perforated. with small holes all over so that it forms a part
of the rose when the pressure is applied to force the fluid or liquid out.
The large holes in the tube attached to the cap allows the syringe to be instantly
filled when the suction stroke is commenced and when the pressure is put on to force
out the fluid or liquid the sliding valve or bucket covers the ring of large holes and
makes it perfectly air tight.
In the accompanying drawings Figure 1 is a front elevation of the compound rose
and sliding valve or bucket.

page_text: Figure 2 is a view showing the front of the cap or rose and sliding valve or
bucket.
Figure 3 is a vertical section of the compound rose and sliding valve cut
through the centre showing the cap inner tube sliding valve or bucket cut in two
. halves.
Figure is a vertical section of a slightly modified compound rose and sliding
valve to be used for a cheap kind of syringe.
Figure 5 showing the front of the cap and sliding valve of this modification.
Figure 6 shows the inner tube of this modified form.
Figure 7 shows the valve or bucket in this modified form.
a is the cap b is the inner tube c is the sliding valve and d is a wire spring to
keep the sliding valve or bucket in its place and indicated by dotted lines in the
drawings.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. The sliding valve or bucket being perforated all over its face with small holes
and to slide in another tube in the manner specified.
2nd. The inner tube being perforated with large holes near the cap to allow of the
syringe being instantly filled when the suction stroke is commenced substantially in
the manner described.
3rd. Is the modified arrangement which is described and illustrated in the
accompanying drawings.
