PROVISIONAL SPECIFICATION.
Improvements in Inflators, Pumps, Syringes, and the like Articles.
We, HERBERT STONE, of Bracebridge Street, in the City of Birmingham,
Manufacturer, and SAMUEL WILLIAM HUGHES, of Witton Lane, Aston, near the
City of Birmingham, Tool Maker, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to improvements in inflaters, pumps, syringes, and the
like articles, and its object is to provide an improved combination of barrel of
paper, paper machie, paper or wood pulp, with metallic fittings, or metallic fittings
combined with part wooden fittings; also improved methods of attaching such
fittings to the said paper &c. barrels.
The desire for the substitution of paper or its like for the usual metallic
barrels of inflaters and their like, has been felt but the difficulties of attaching
a plunger rod and the necessary end fittings have hitherto not been overcome, and
hence this invention.
In this description when speaking of the barrel, it will be understood that the
term paper is meant to include any of its analogous substances as before enumer-
ated for instance.
As applied to a pump in which the barrel proper telescopes into the handle
barrel, and in which the plunger rod is secured at the inner end of the handle
it is made as follows:
A length of paper tube is cut for the handle and one for the plunger barrel.
In the one end of the handle is now glued or cemented a wooden plug, which if
desired, in some cases, may be surmounted by a cap of thin metal whose edge
may be closed down tightly on the paper pressing the latter somewhat into the
interior plug. In the centre of the plug is a hole into which the end of the
plunger rod may be screwed, eyeletted or otherwise secured. At the other end
of the handle an exterior strengthening ring of metal or of paper is secured. The
outer end of the barrel proper is similarly treated, that is to say, a wooden plug
may be secured in which is a central hole (screwed or otherwise as required)
for the nozzle pipe attachment. In such cases where the plunger rod or the
nozzle pipe is connected, and where a metallic central screw hole is desired in
combination with a wooden plug a central boss may be formed upon a surround-
ing cap in which such screw hole may be made, and the cap secured as before
described.
At the upper end of the barrel, that is, through which the plunger rod works
a screwed ring (or internal collar) may be pushed inside the tube and there
secured by an external ring being tightly forced thereon, or even further spun or
closed somewhat thereinto from the outside. Into this fitting the ordinary
removable cap is screwed. Or in some cases an outwardly extending part of such
inner ring may be spun or turned back on towards itself with the paper tube
tightly held between. In some cases it may be necessary to form the plugs
entirely of metal, and secure them to the tube by caps, or external rings, or by
their own extensions, by the spinning or closing down processes before described.

page_text: In any of the above cases where a wooden plug, can be employed relianco
is given to the glueing or cementing of such parts, or this may be supplemented
by any of the above-named methods.
The interior of the tubes is rendered oil proof by means of a coating of tanned
gelatine, while the exterior, is mado waterproof by any of the well known means.
Dated this. 16th day of July 1898.

Improvements in Inflators, Pumps, Syringes, and the like Articles.
We, HERBERT STONE, of Bracebridge Street, in the City of Birmingham,
Manufacturer, and SAMUEL WILLIAM HUGHES, of Witton Lane, Aston, near the
City of Birmingham, Tool Maker, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
This invention relates to improvements in inflators, pumps, syringes, and the
like articles, and its object is to provide an improved combination of barrel of
paper, paper machie, paper or wood pulp, with metallic fittings, or metallic fittings
combined with part wooden fittings; also improved methods of attaching such
fittings to the said paper &c. barrels.
The desire for the substitution of paper or its like for the usual metallic
barrels of inflators and their like has been felt, but the difficulties of attaching
a plunger rod and the necessary end fittings have hitherto not been overcome, and
hence this invention.
In order to more clearly explain this our invention we have appended here-
unto an illustrative drawing upon which are figures and numbers of reference.
Fig. 1, shows this our invention applied to an inflator.
Figs. 2, 3, 4, 5, 6, 7 & 8, show modifications in the construction of and method
of securing the several ends of the barrels.
In this our specification when speaking of the barrel it will be understood
that the term paper is meant to include any of its analogous substances as before
enumerated.
As applied for instance as seen in Fig. 1, to a pump in which the barrel 10,
telescopes into the handle barrel 11, and in which the plunger rod 12, is secured
at the inner end of the handle, it is made as follows:-
A length of paper tube is cut for the handle 11, and one for the plunger
barrel 10. In the one end of the handle is now glued or cemented a wooden
plug 13, which if desired, in some cases may be surmounted by a cap 14, of thin
inetal whose edge 15, may be closed down tightly on to the paper 11, pressing the
latter somewhat into the interior plug. In the centre of the plug is a hole into
which the end of the plunger rod 12, may be screwed, eyeletted or otherwise
secured. At the other end of the handle an exterior strengthening ring 16, of
metal or of paper is secured. The outer end of the barrel 10, is similarly treated,
that is to say, a wooden plug 17, may be secured in which is a central hole 18,
(screwed or otherwise as required) for the attachment of the nozzle pipe 19. In
cases where it is desired to provide a metallic central hole for the attachment of
the plunger rod 12, or the nozzle pipe 19, in combination with a wooden plug,
a central boss 20, see Fig. 2, may be formed upon the surrounding cap 14, in

page_text: which such screw hole may be made, and the cap secured as before described
upon the barrel and plug.
At the upper end of the barrel, that is, the part through which the plunger
rod works, an internally screwed ring collar 22, may be pushed inside the tube 10,
and there secured by an external ring 23 being tightly forced thereon, or even
further spun or closed somewhat thereinto from the outside, see Figs. 1 and 4.
Into this fitting 22, the ordinary removable cap 24 is screwed. Or in some cases
an outwardly extending part 25, see Figs. 5 and 6, of such inner ring 22, may
be spun or turned back on towards itself with the paper tube tightly held
between.
If desired a ring 22", may be used within the barrel end, as seen in Figs. 3,
7 and 8, instead of the wooden plug,, the external cap being as before described
tightly closed on to the paper barrel.
In some cases we may form the plugs entirely of metal and secure them to the
tube as before described, by caps, or external rings, or extensions such as 25,
see Figs. 3, 5, 6 and 8, may be ormed upon them, by which they may be secured,
and all by the spinning or closing down processes before described.
In any of the above cases where a wooden plug can be employed, reliance is
given to the gluing or cementing of such parts, or this may be applied to or
supplemented by any of the above-named methods.
The interior of the tube may be rendered oil proof by means of a coating of
tanned gelatine, while the exterior is made waterproof by any of the well known
means, but this forms no part of this our invention.
Having now particularly described and ascertained the nature of our said
invention, and the manner in which the same is to be performed, we declare that
what we claim is: --
Forming and attaching the ends upon paper and the like barrels by means of
metallic caps and rings, with or without wooden plugs, substantially as herein
set forth and shown and for the purposes specified.
