Improvements in Inflators for the Pneumatic Tyres of Velocipedes
and the like.
We, FRANK HENRY BLUEMEL, CHARLES WILLIAM BLUEMEL, and ERNEST
ADOLPHUS BLUEMEL (trading as C. W. Bluemel & Bros.), of Crown Works, Rose
Place, Globe Road, Mile End, London, E. Manufacturers, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to improvements in inflators for the pneumatic tyres of
velocipedes and the like, the object of which is to arrange or construct an inflator
in such a manner as to allow of its being used either as a hand pump or inflator,
or as a foot pump or inflator, at the same time retaining all the advantages of
the former as regards portability and ease of carrying, combined with the power
and advantages of the latter as regards ease of manipulation, etc.
In carrying our invention into, practical effect, the inflator proper is mainly
of the ordinary construction, and comprises an outer cylinder or tube within
which works a plunging rod fitted at the end with the ordinary cup valve.
The handle designed to be secured at the end of the plunging rod or tube is
constructed separately and of suitable shape, while it is arranged in such a manner
as to screw on to the end of the aforesaid plunging rod or tube at right angles
to same when operating the pump, while the said tube or rod may be screwed into
the end of the handle in such a manner as to allow of it's lying horizontally with
the pump or inflator for convenience in attaching it to one of the tubes of the
frame of a velocipede.
The pump is furnished near the bottom with an opening for the exit or passage
of the air and to which may be screwed one end of a flexible connecting tube,
preferably carried, when not in use, down the tubular or hollow plunging tube or
rod.
We further provide a foot piece comprising a suitably shaped open frame
formed by bending or shaping a strip of suitable springy material to the required
form, the free ends of this frame being bent inwards towards each other and at
right angles to the sides of the said foot plate or frame, in such a manner as to
allow of its being readily sprung into holes or perforations formed in a plug
closing the end of the said inflator, while when not required for use it can be
easily carried in the pocket, tool bag, or the like.
an
When required for use, the flexible connecting tube is screwed into the open-
ing or perforation formed near the bottom of the pump designed to receive it,
and the end of the plunging tube or rod may be screwed into the end of the
handle so as to lie horizontally with it, when the device may be used as
ordinary pump or inflator, when however it is required to be used as a foot pump
or inflator, the end of the aforesaid plunging tube or rod is screwed into the
centre of the handle in such a manner that the latter is at right angles to same,
while the frame forming the foot plate is sprung into position.

We, FRANK HENRY BLUEMEL, CHARLES WILLIAM BLUEMEL, and ERNEST
ADOLPHUS BLUEMEL (trading as C. W. Bluemel & Bros.), of Crown Works, Rose
Place, Globe Road, Mile End, London, E. Manufacturers, 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:-
Our invention relates to improvements in inflators for the pneumatic tyres of
velocipedes and the like, the object of which is to arrange or construct an inflator
in such a manner as to allow of its being used either as a hand pump or inflator,
.or as a foot pump or inflator, at the same time retaining all the advantages of
the former as regards portability and ease of carrying, combined with the power
. and advantages of the latter as regards ease of manipulation, etc.
In carrying our invention into practical effect, the inflator proper is mainly
of the ordinary construction, and comprises an outer cylinder or tube within
which works a plunging rod fitted at the end with the ordinary cup valve.
The handle designed to be secured at the end of the plunging rod or tube is
constructed separately and of suitable shape, while it is arranged in such a manner
as to screw on to the end of the aforesaid plunging rod or tube at right angles
to same when operating the pump, while the said tube or rod may be screwed into
the end of the handle in such a manner as to allow of its lying horizontally with.
the pump or inflator for convenience in attaching it to one of the tubes of the`
frame of a velocipede.
The pump is furnished near the bottom with an opening for the exit or passage
of the air and to which may be screwed one end of a flexible connecting tube,
preferably carried, when not in use, down the tubular or hollow plunging tube or
rod.
We further provide a foot piece comprising a suitably shaped open frame
formed by bending or shaping a strip of suitable springy material to the required
form, the free ends of this frame being bent inwards towards each other and at
right angles to the sides of the said foot plate or frame, in such a manner as to.
allow of its being readily sprung into holes or perforations formed in a plug
closing the end of the said inflator, while when not required for use it can be
easily carried in the pocket, tool bag, or the like.
When required for use, the flexible connecting tube is screwed into the open-
ing or perforation formed near the bottom of the pump designed to receive it,
and the end of the plunging tube or rod may be screwed into the end of the
handle so as to lie horizontally with it, when the device may be used as an
ordinary pump or inflator, when however it is required to be used as a foot pump
or inflator, the end of the aforesaid plunging tube or rod is screwed into the
centre of the handle in such a manner that the latter is at right angles to same,
while the frame forming the foot plate is sprung into position.
In order that our invention may be more fully understood, we will now pro-
ceed to describe same with reference to the accompanying drawings in which,
Fig. 1 is a side elevation of the inflator in the position ready for carrying with
the foot plate or frame in the raised position.
Fig. 2 is an elevation of the inflator ready for use as a foot pump.
Fig. 3 is a longitudinal section through the handle approximately full size,
and Fig. 4 is a plan of the foot plate or frame.
The inflator which is mainly of ordinary construction comprises an outer
cylinder or tube a within which works a plunging rod 6 fitted with an ordinary
4

page_text: cup valve. The handle c is furnished at one side and approximately at the centre
of the handle with a screw cap d while within the said handle, which is hollow,
a second screw cap or screw ring 9 is arranged in such a manner that the said
handle c may be connected to the plunging_rod either vertically or at right
angles to the said plunging rod as shown at Figs. 1 and 2 respectively.
The lower part of the inflator is furnished with air outlet h while the extremity
of the outer cylinder or tube a is closed by means of a suitable plug having a
hole bored through same to receive the in-turned ends m of the foot plate p
(Fig. 4) which is formed of suitable springy material and preferably of the shape
shown.
The flexible connecting tube q is preferably carried in the hollow plunging
rod b, while the foot plate p when not required for use, may be turned up against
either side of the body a of the inflator, or it may be sprung out from the hole
or perforations, and carried separately in the pocket or saddle bag.
In order to use the inflator after the manner of an ordinary hand pump, it is
employed when in the position shown at Fig. 1, the flexible connection 7 being
screwed into the air outlet h, when a tyre or the like can be inflated in the ordinary
manner, when however it is required to be used as a foot pump, the handle e is
reversed, that is to say, screwed on at right angles to the plunger rod b, the foot
plate or frame is turned down, or where it has been previously removed, is sprung
in position as shown at Fig. 2, so that by placing the foot upon the said plate
the inflator is kept firm and steady and the tyre or the like can be inflated as
easily and speedily as where one of the ordinary and well known foot pumps is
employed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
1. The construction and arrangement of an inflator fitted with a reversible
handle and a detachable foot plate or frame substantially as herein described
and shown, and for the purposes specified.
2/. The combination of an inflator or pump with a reversible handle such as c
fitted with screwed caps or rings such as q, d, and a detachable foot plate or
frame such as p, substantially as set forth.
3/. The combination of an inflator or pump with a detachable foot plate or
frame having its ends turned in at right angles to the sides, and designed to
engage with a hole or perforation formed in the end of the inflator which is suit-
ably closed for this purpose, substantially as described and shown and for the
purposes specified.
