PROVISIONAL SPECIFICATION.
Improvements in Inflators or Pumps.
We, HERBERT STONE, of Bracebridge Street; in the City of Birmingham; Manu-
facturer, and WILLIAM JOHN POWELL, of 3 Park Grove, Park Road, in the City
of Birmingham, Brass-worker, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in inflators or punips, in which a nozzle
pipe, which is usually flexible, but which may be otherwise is used either as a
jet or spray or as a connection from the barrel or the plunger rod, as the case
may be, to the body to be inflated &c.
It consists as follows:-The plunger rod is tubular as is usual. Within this
rod is placed the one end of the nozzle pipe, the said pipe being furnished thercat
with a piston cup leather, or washer &c., which shall permit of a sliding movement
within the rod, but which will be air or water tight. A screw cap or other
suitable contrivance is placed upon the end of the rod to prevent the entire with-
drawal of the said nozzle pipe. The other end of the nozzle pipo is furnished
with the usually required nozzlo screw or other fitting.
By these means the said nozzle pipe may be readily pushed back within tho
plunger rod, out of the way when not in use without any detachment, and as
readily withdrawn when required.

Improvements in Inflators or Pumps.
We, HERBERT STONE, of Bracebridge Street, in the City of Birmingham, Manu-
facturer, and WILLIAM JOHN POWELL of 3 Park Grove, Park Road, in the City
of Birmingham, Brass-worker, 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 invention relates to improvements in inflators or pumps, in which a nozzle
pipe, which is usually flexible, but which may be otherwise is used either as a
jet or spray or as a connection from the barrel or the plunger rod, as the caso
may be, to the body to be inflated &c.
In order to more clearly explain this our invention we have appended hereunto
an illustrative sheet of drawings upon which are figures and numbers of reference
in which :-
Fig. 1 is a sectional elevation of the invention showing the nozzle pipe with-
drawn ready for use.
Fig. 2 is a similar view, but showing the nozzle pipe pushed back into the
plunger tubular rod, out of the way.
Fig. 3 shows its application to a different arrangement of pump.
D

page_text: Referring to Figs. 1 & 2-5 is the pump barrel. 6 is the plunger (or piston).
7 is the plunger rod which is tubular having the necessary valve at the plunger end.
8 is the nozzle pipe at the outer end of which is secured the nozzle 9. Within tho
rod 7 is placed the nozzle pipe 8, at whose inner ond is the cup leather or
washer 10, or is formed the piston 10" as seen in Fig. 3, which permits of a
sliding movement of the nozzlo pipe 8 within the rod 7, but which is air or water
tight. By bulbing or enlarging the fitting 13 at 14, see Fig. 3, the flexible
tubo 8 is swelled to fit tightly the tube 7, and effectually prevents any escape of
air when in use.
A screw cap 11 or other suitable contrivance is now threaded on to the pipo 8 and
screwed on the rod 7 so as to prevent the entire withdrawal of the nozzle pipe 8.
Referring again to Fig. 3 it will be seen that the nozzle pipe 8 is applied to
the rod 7 precisely as before except that the screw cap 11 shown in Figs. 1 & 2
is dispensed with and another well known form of pump is used, in which tho
handle 12 is made to act as one with, and slide with, the rod 7, hence the front
end of the handle at 11 forms the cap to prevent entire withdrawal of the pipo 8,
the latter pipe in this case being pushed up the rod 7 from the other end before
the plunger 6 is attached or if desired a separate small
used at 11.
cap or bush may be
By these means the said nozzle pipe may be readily pushed back within the
plunger rod, out of the way when not in use without any detachment, and as
readily withdrawn when required.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performal, we declare that what
we claim is
1. In inflators or pumps the combination with a barrel 5 and plunger 6, of a
tubular plunger rod 7 in which a sliding nozzlo pipe 6 is made to slide in and
out as may be required, arranged and operating substantially as set forth and shown.
2. In inflators or pumps the forming or making of a piston within a tubular
rod such as 7 by means of an enlargement, or swell 14 upon an interior fitting
such as 13 upon which the flexible pipe 8 is passed substantially as shown and
described.
