Improvements in Inflaters or Hand Air Pumps, and in Attachments
for same.
We, WILLIAM BOWN, 308, Summer Lane, Birmingham in the County of
Warwick, Manufacturer, and GEORGE CAPEWELL, 114 Upper Thomas Street,
Aston juxta Birmingham aforesaid, Machinist do hereby declare the nature of this
invention to be as follows:
This invention has reference to inflaters or hand air pumps for inflating pneumatic
tyres and similar articles, the objects of which are-Firstly-To provide improved
means for holding or supporting the inflater or hand air pump whilst being operated
upon. Secondly-In providing easier means for connecting and disconnecting the
connections of an inflater or hand air pump to the said inflater or hand air pump
and also in connecting and disconnecting the inflater or hand air pump to the valve
of the tyre or other object which it is intended to inflate. Thirdly-Improved
means for guiding or keeping the piston or piston rod or equivalent when working
in its proper position and also in reducing the friction. Lastly-An improved
method of protecting the check valve.
With reference to the first part of our improvements we joint, swivel or connect
to any convenient part of an inflater or hand air pump a suitable support of stay
rod or rods, or rest or their equivalent in such a manner as to support the said
inflater or hand air pump when in use. One end of the said support or equivalent
is formed so as to take into or against a corresponding part or hold fast or equi-
valent jointed, pivotted, attached to or formed out of any convenient part of the
cycle or other like machine or article. Or the said support or equivalent may be
attached to the cycle or other like machine or article and the corresponding part or
hold fast attached to the inflater or hand air pump. Or the said end of the support
or equivalent may be pointed or otherwise shaped or covered with rubber or other
suitable material or have an independant piece attached thereto so that it can rest
upon the ground or floor or bear upon the rim or other convenient part of the cycle
or other like machine or article. The support or equivalent when made to fold is
held in its open or closed position by means of a catch or spring or other suitable
locking device. We may when desired dispense with the support or equivalent
and form the nozzle of the inflater or hand air pump so as to take into or against a
corresponding part or holdfast or equivalent jointed, swivelled or attached to or formed.
out of any convenient part of the cycle or machine or other like article, or the said
corresponding part or holdfast may be made so as to rest upon the ground or floor or
other convenient place. A suitable rubber tube or other means being provided for
conveying the air from the corresponding part or holdfast or equivalent to the
valve of the rubber tyre or other article being inflated. The said corresponding
part or holdfast or equivalent, or rubber tube or equivalent may if desired be
provided with a suitable check valve.
For the purpose of more readily or more easily connecting and disconnecting the
inflater or hand air pump or any other connections or parts of the said'inflater or
hand air pump we form the necessary parts with a suitably shaped slot or slots or
an inclined clutch or clutches either separate or in combination with a spring
fastening or equivalent, which said slot or slots or equivalent take into or against a
peg or pegs or other suitable device formed on or connected to the corresponding
part of the connections or other parts, or vice versa.
In order to more effectually guide or keep the piston or piston rod or equivalent
when working in its proper position and to reduce the friction thereon we attach to

page_text: the said piston or piston rod or equivalent a suitably shaped washer of vulcanite,
rubber, wood or any other suitable material having serrated edges or holes formed
therein so as to allow the air to pass freely through. Instead of using a serrated
washer we may if desired employ a suitably shaped guide piece provided with
small rollers or steel balls or other antifrictional bearings or equivalent on its edges.
We may also when desired provide the hole in the lid or cover of the inflater or
hand air pump through which the piston or piston rod or rods or equivalent pass,
or any other part connected therewith with balls, small rollers or any other
suitable antifrictional bearings or guides.
To enable us to more effectually protect the check valve of an inflater or hand
air pump we form the parts to which the said check valve is connected so that the
said parts are below the level of the outer surface of the bottom cap or cover of
the said inflater or hand air pump. Or we may recess the bottom cap or cover
and insert the check valve therein; or insert the said check valve in a small cup
or cover and screw the said small cup. or cover into the bottom cap or cover of the
inflater or hand air pump.

Improvements in Inflaters or Hand Air Pumps, and in Attachments
for same.
We, WILLIAM BOWN, 308 Summer Lane, Birmingham in the County of
Warwick, Manufacturer and GEORGE CAPEWELL, 114 Upper Thomas Street,
Aston juxta Birmingham aforesaid, Machinist, 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 has reference to inflaters or hand air pumps for inflating pneumatic
tyres and similar articles, the objects of which are-)
-Firstly-To provide improved
means for holding or suporting the inflater or hand air pump whilst being operated
upon Secondly-In providing easier means for connecting and disconnecting the
connections of an inflater or hand air pump to the said inflater or hand air pump
and also in connecting and disconnecting the inflater or hand air pump to the
valve of the tyre or other article which it is intended to inflate-Thirdly.
Improved means for guiding or keeping the piston or piston rod or equivalent
when working in its proper position and also in reducing the friction-Lastly-
An improved method of protecting the check valve.
1
In order that our invention may be better understood we have illustrated same
in the accompanying drawings.
Figs. 1 and 2 shew the first part of our invention as adapted to the rim of a
wheel
Fig. 3 shews the same part of our invention as adapted to be fixed to the wall or
any other convenient place.
Fig. 4 shews a similar method to Fig. 3 with the outlet valve separate from the
pump, and
Fig. 5 shews another arrangement of the first part of our invention.
With reference to Figs. 1 and 2 A is the inflater or hand air pump and B the
nozzle. Formed on the end of the said nozzle B is a peg C or equivalent which
takes into a corresponding part or holdfast D suitably connected to the valve E of
the rim F, or the said holdfast D may be connected to the said rim F. Or the
hold fast D may be formed on the end of the nozzle B and the peg connected to
the valve E or the rim F. Forming part of the said nozzle B is a suitable outlet
valve G which is connected by means of the india rubber tubing H to the said
valve E. Or the said outlet valve G may be attached to or formed out of the

page_text: hold fast D or attached to the rim F. At Fig. 3 we have shewn our improvements
as adapted to be used with the bracket I which can be fixed to the wall or any
other convenient place. In this case the nozzle B is connected to the universal
joint J which forms part of the said bracket I and the tubing H which is connected
to the outlet valve G is made long enough so that the connection a can be secured
to the valve of the tyre or other article intended to be inflated or to any con-
nections thereof. Instead of the outlet valve G forming part of the nozzle B we
may if desired form the said outlet valve G in connection with the universal
joint J as shewn at Fig. 4.
Fig. 5 shews our invention as used with a support or rod K. The said rod K,
which may be of any length is secured to the nozzle B or to any other convenient
part of the pump A. A suitable piece of rubber b is provided at the end of the
support or rod K to prevent the said support or rod K from slipping when in use.
Instead of the outlet valve G being connected to the nozzle B as shewn (see
Fig. 5) we may if desired connect the said outlet valve G to any part of the
support or rod K. The said support or rod K may be hinged or swivelled if
desired so as to fold alongside with the pump A.
With reference to the second part of our invention which we have illustrated at
Fig. we form the connection L with a suitable slot c and the corresponding con-
nection M with a peg or equivalent d, which said peg d takes into the said slot c
thereby securely connecting the two connections L and M together.
Figs. 7 and 8 illustrate the third part of our invention for more effectually
guiding or keeping the piston or piston rod or equivalent when working in its
proper position. This we effect by means of the washer N which is made of
vulcanite or other suitable material and is connected to the end of the piston rod.
The said washer N is serrated on its edge as shewn or a suitable number of holes
may be formed in it so as to allow the air to pass freely through. Instead of
serrating the edge of the washer N we may if desired provide the said washer N
with a suitable number of rollers e as shewn at Fig. 8 or other antifrictional
bearings. We may also when desired provide the hole in the lid or cover f of the
inflater A through which the piston rod works or any other part connected there-
with with a suitable number of small rollers or balls or other antifrictional bearings
or guides.
Lastly our invention relates to an improved means for protecting the check valve,
which we have illustrated at Fig. 9. On the end or cover O of the inflater A
we form a recessed boss P or equivalent into which the valve R is secured, the
said boss P or equivalent forming a shield for protecting the said valve R.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we would have it understood that
we do not bind ourselves to the precise details as herein shewn, as they may be
varied without departing from the nature of our invention, but what we wish to
claim is :-
Firstly The means substantially as herein shewn and described for supporting
the inflater or hand air pump with reference to Figs. 1 and 2.
Secondly Connecting to or forming out of the holdfast D or equivalent the
outlet valve G for the purpose substantially as herein described.
:-
Thirdly-Forming out of or attaching to any convenient part of the cycle the
corresponding part or holdfast either with or without the outlet valve or opening.
Fourthly The use of the jointed or swivelled support or other holdfast or
stay rod or equivalent in combination with the nozzle or other convenient part of
the inflater substantially as herein described and shewn with reference to Figs. 3, +
and 5.
Fifthly: The means substantially as herein shewn and described for connecting
or disconnecting the connections of an inflater or hand air pump.
Sixthly-The use of the guide or washer substantially as herein described and
shewn with reference to Fig. 7.
