PROVISIONAL SPECIFICATION.
An Improved Connection for Cycle and like Inflators or Pumps.
I, HARRY LUCAS, of Tom Bowling Lamp Works, Little King Street, in the
City of Birmingham, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to cycle and like inflators or pumps and its object is to.
provide a neater and more convenient device for connecting the air tube to the end
of the pump while at the same time allowing the air tube to be reversed and
placed within the pump when not in use for pumping up the pneumatic tyre.
My invention consists in a particular arrangement of connecting nozzle or union,
connecting the rubber air tube to the pump.
In constructing a nozzle or union in accordance with my invention I provide a
female screw at one end of the said nozzle to screw over the externally screwed
end of the pump piston tube; at the other end I provide the usual nipple or tube
suitably arranged to slip within the rubber tube connecting piece. Around this
nipple or tube' at its base I cut an annular recess and in this recess I provide a
female screw of the same diameter as the first mentioned female screw and of the
same thread. .
To pump up the tyre I connect the union by the first mentioned screw to the
pump, leaving the rubber tube projecting from the pump. When the tyre is..
pumped up I disconnect the tube, reverse it and slip, the rubber tube within .the
hollow of the pump tube and screw the second female screw over the pump tube.
I can thus screw a cap into the internal screw now outside and so I produce. a
pump with the rubber supply tube very neatly hidden and closed in free from.
access of dust when not in use for pumping.
-
:
By my invention I produce a neatly. finished union which has two internal screws
one at each end of the cylindrical piece forming the base of the nozzle and one of
these screws is formed in a recess cut round the nozzle.

An Improved Connection for Cycle and like Inflators or Pumps.
1, HARRY. LUCAS, of Tom Bowling Lamp Works, Little King Street, in the
City of Birmingham, Manufacturer, 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 cycle and like inflators or pumps, and its object is to
provide a neater and more convenient device for connecting the air tube to the end
of the pump, while at the same time allowing the air tube to be reversed and
placed within the pump when not in use for pumping up the pneumatic tyre.

page_text: My invention consists in a particular arrangement of connecting nozzle or union,
connecting the rubber air tube to the pump.
In the accompanying sheet of explanatory drawings to be hereinafter referred to.-
Figure 1 is a plan of my improved connecting nozzle or union with the rubber
air tube attached thereto.
Figure 2 is an enlarged sectional view of the nozzle or union.
Figure 3 is a sectional plan representing the air tube attached by means of the
nozzle or union to the piston or plunger tube, and in position for inflating the tyre.
Figure 4 is a plan with part in section, showing the nozzle or union reversed and
the air tube inserted within the piston or plunger tube.
Figure 5 is a part sectional plan illustrating the piston tube fitted with a finger
grip in place of a tubular_handle._
The same reference letters in the different views indicate the same parts.
In constructing a nozzle or union such as A in accordance with my invention,
I provide a female screw at one end of the said nozzle to screw over the externally
screwed end of the pump piston or plunger tube B; at the other end I provide the
usual nipple or tube A¹ (Figure 2) arranged to slip within the rubber tube C.
Around this nipple or tube at its base I cut an annular recess A2, and in this recess
I provide a female screw of the same diameter as the first mentioned female screw,
and of the same thread. The central portion of the exterior surface of the nozzle
or union is milled as illustrated at Figure 1, in order that it may be conveniently
grasped by the fingers.
To pump up the tyre I connect the union A by the first mentioned screw to the
projecting end of the piston tube B with the rubber tube C projecting from the
pump as shown at Figure 3. When the tyre is inflated to the desired extent,
disconnect the union, reverse it, and slip the rubber tube C within the hollow of
the piston tube B, as shown by dotted lines at Figure 4. I then screw the cap D
into the internal screw now outside, and thus produce a pump with the rubber
supply tube very neatly hidden and closed in free from access of dust when not in
use for pumping.
Instead of fitting a handle tube such as E upon the piston tube B as illustrated
at Figures 3 and 4, I sometimes employ a finger grip such as F, Figure 5, and
I make such other modifications as may be necessary to meet the requirements of
varying services, without departing from the essential features of my invention.
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. In cycle and like inflators or pumps the use of a reversible nozzle or union
substantially as and for the purposes described.
2. The improved nozzle or union for a cycle or like inflator or pump consisting
of a nut or connecting piece with a central disc forming the base of a nipple
projecting therefrom, and having similar internal screw threads cut within each
end, substantially as and for the purposes hereinbefore described, and as illustrated
in the accompanying drawings.
