page_text: I, EDOUARD WICKY, of Bâle, in the Republic of Switzerland, Merchant, do hereby
declare the nature of this invention to be as follows:-
My invention refers to air-pumps as used for inflating pneumatic tyres and more
especially to those pumps which are of relatively small dimensions, being intended to
be used by holding one of their parts, say the cylinder, in one hand and the other one,
say the piston in the other hand whilst the cylinder is connected by means of a
flexible tube to the usual air-valve of the pneumatic tyre.
The purpose of my invention is to greatly facilitate the pumping of air by means
of such pumps and it consists of a rigid bearing or support substantially formed like
a crutch, the foot-end of which is fixed to the one portion of the air-pump and the
forked end of which is intended to bear against the wheel-rim of the cycle
the pneumatic tyre of which is to be inflated, in view of allowing the one portion of
the air-pump to which the said crutch is fixed to be pressed by one hand against the
wheel-rim whilst the other hand imparts a to-and-fro-motion to the other portion of
the pump, this rigid connection between one portion of the air-pump and the wheel-
rim greatly facilitating the operation of inflating the tyre.
The said support or crutch may be fixed either to the cylinder or to the piston
rod of the air-pump and its free end, which will preferably be forked like a walking-
crutch may be provided with suitable hooks or notches for hooking itself to the
wheel-rim or other portion of the cycle.
The ends of the said forked portion of the crutch may further be formed so as to
be used as a tool for removing the pneumatic tyre from the wheel-rim, or for turning
screws or screw-nuts or for doing any other similar work.
The said support or crutch will preferably be provided with a suitable joining-tube
intended to connect the usual flexible tube, which is designed to be connected to the
valve of the tyre, with the cylinder of the air pump and the said joining-tube will be
made so as to fulfil at the same time the connection of the flexible tube and the
connection of the said support or crutch with the cylinder of the air pump, and
the screw-thread of the said joining-tube will preferably be made so as to suit the
usual thread of the hole of the cylinder of the air-pumps actually in trade, or other
means may be provided in view of allowing the support or crutch making the object
of this invention to be combined with the existing air-pump for cycles.

page_text: I, EDOUARD WICKY, of Bâle, in the Republic of Switzerland, Merchant, 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 refers to air-pumps as used for inflating pneumatic tyres and more
especially to hand-pumps being intended to be used by holding one of their parts,
say the cylinder, in one hand. and the other one, say the piston in the other hand
whilst the cylinder is connected by means of a flexible tube to the usual air-valve of
the pneumatic tyre.
The purpose of my invention is to greatly facilitate the pumping of air by means
of such pumps and it consists of a rigid bearing or support substantially formed like
a crutch, the foot-end of which is fixed to the one portion of the air-pump and the
forked end of which is intended to bear against the frame, the wheel-rim or any
other suitable portion of the cycle the pneumatic tyre of which is to be inflated, with
the object of allowing the one portion of the air-pump to which the said crutch is
fixed to be pressed by one hand against the wheel-rim or against any other suitable
portion of the cycle, whilst the other hand imparts a to-and-fro-motion to the other
portion of the pump, this rigid connection between one portion of the air-pump and
the wheel-rim or other portion of the cycle, greatly facilitating the operation of
inflating the tyre.
The said support or crutch may be fixed either to the cylinder or to the piston
rod of the air-pump and its free end, which will preferably be forked like a walking-
crutch may be provided with suitable hooks or notches for hooking itself to the wheel
or other portion of the cycle.
The ends of the said forked portion of the crutch may further be formed so as to
be used as a tool for removing the pneumatic tyre from the wheel-rim, or for turning
screws or screw-nuts or for doing any similar work.
The said support or crutch may be provided with a suitable joining-tube intended
to connect the usual flexible tube, which is designed to be connected to the valve of
the tyre, with the cylinder of the air-pump and the said joining-tube will be made so
as to fulfil at the same time the connection of the flexible tube and the connection of
the said support or crutch with the cylinder of the air-pump, and the screw-thread
of the said joining-tube will preferably be made so as to suit the usual thread of the
hole of the cylinder of the air-pumps at present in use, or other means may be
provided for allowing the support or crutch forming the object of this invention to
be combined with the existing air-pumps for cycles.
The accompanying drawing represents, by way of example, one form in which the
invention is carried into practice.
Figure 1 is a longitudinal section of an air-pump provided with a support in
accordance with my invention and connected to a wheel-rim, the pneumatic tyre of
which is represented partly in plan and partly in section.
Figure 2 is a front elevation of the support in the form of a crutch, and
Figure 3 is an underside view of Figure 2.
The same letters of reference refer to corresponding parts in the several figures.
A is the cylinder of the pump and B its piston, the hollow rod 6 of which is used
at the same time as a compressing tube. At the end of the said piston-rod is fixed,
as in the usual air-pumps, the connecting tube C, bearing a flexible tube D, the other
end of which is connected to the valve E of the air-chamber F disposed in the
wheel-rim G.
H is the support in the form of a crutch (Figure 2) consisting of a base h¹,

page_text: disposed so as to be fixed to the pump, a rigid part 2 of suitable length and of a
head formed so as to adjust itself to one portion of the wheel or to any other
portion of the cycle, for instance to the wheel-rim G, as shown in Figure 1.
The base his formed here of a flange which is adapted to be inserted between the
connecting-tube C and the end of the tubular rod b as seen in Figure 1.
The support H may be made of one piece with one of the parts of the pump; its
rigid portion may have any suitable shape whatever and its end 13 may also vary
according as it is desired to bear against the wheel-rim or against the spokes of the
wheel or against any other portion of the cycle.
One of its horns may be bent for instance in the shape of a hook to catch the
edge of the wheel-rim or the spoke of the wheel.
The part 3 will be preferably covered over with an india-rubber or leather
envelope so as not to damage the varnish of the wheel-rim or other portion of the
cycle against which it is applied.
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. A rigid support for a hand pump for inflating pneumatic tyres, composed of a
rigid prolongation of one of the parts of the air-pump, ending with a head formed so
as to be applied firmly against any suitable portion of the cycle, substantially as and
for the purpose specified.
2. A rigid support of a hand pump for inflating pneumatic tyres, composed of a
rigid prolongation of one of the parts of the pump, ending with a head formed so
as to be applied firmly against any suitable portion of the cycle, disposed so as to be
adapted to be fixed to the existing hand pumps, substantially as shown and described.
3. A rigid support of a hand-pump for inflating pneumatic tyres, composed of a
rigid prolongation of one of the parts of the pump, ending with a head formed so
as to be applied firmly against any suitable portion of the cycle, formed of a flange h¹
adapted to be inserted between the connecting tube C and the rod b of the pump, of
a rigid part 2 of any suitable shape whatever and of a head h³ in the form of a crutch,
substantially as shown and described.
