Improvements relating to Pumps for Inflating Pneumatic Tyres.
1, EDWARD BOOTH, of 19, Wretham Road, Handsworth, in the County of
Stafford, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention consists of improvements relating to pumps for inflating the
pneumatic tyres of cycle and other vehicle wheels.
My object is to dispense with an independent inflator, such as is now in ordinary
use, by forming the pump barrel or cylinder as a part of the vehicle framing, and
thus to construct a simple pump with a long piston or plunger stroke, that shall be
always secure in a position adapted for convenient and effective operation when
required.
my
In the application of my invention to the construction of a pump or inflator for a
cycle of the safety type, I preferably adapt the diagonal tube stay to serve as the
barrel or cylinder, the plunger being fitted within this tube. The plunger rod
extends through the upper side of the tubular saddle pin at its junction with the
diagonal stay, a suitable cap or gland being provided to prevent vibration of the
rod during the propulsion of the cycle. A convenient handle is fitted to the outer
extremity of the rod, immediately beneath the saddle, and to permit of access to
the same, and to allow of the reciprocation of the pump plunger, I provide flaps or
a detachable piece in the saddle seating. The air is admitted to the barrel or
cylinder through apertures in the cap or gland, and is discharged on the in-stroke
of the plunger through a non-return valve fitted at the lower end of the barrel and
in such a position that the flexible connecting tube can be attached to the tyre valve
of either the front or rear wheel.
I sometimes employ a detachable handle for operating the pump, fixing it upon
the outer extremity of the plunger rod which I cause to project through a
ventilation hole or other aperture in the saddle when the pump is to be worked.
Instead of fitting the pump plunger within the diagonal stay as hereinbefore
described, I sometimes fit it within another portion of the tubular framing of the
cycle, or in a separate tube rigidly fixed to the framing.
When constructing a pump for inflating the pneumatic tyres of a broughan, an
auto-car, or other like vehicle, I form the barrel or cylinder from a part of the
under-framing, or from a tube rigidly fixed or secured to the same, and in such
convenient position as to make it available for simultaneously inflating all the
tyres of the vehicle. I preferably so arrange the plunger and the valves of the
oump for such a service, as to provide a double action, the air being drawn into
and discharged from the barrel at each end, on opposite sides of the plunger.
I do not limit the application of my invention to a cycle or other vehicle of any
particular type or pattern, but adapt the same, with such modifications as may be
ecessary, to the various forms of road vehicles having wheels fitted with pneumatic
yres.

I, EDWARD BOOTH, of 19 Wretham Road, Handsworth, in the County of
Stafford, 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 :-
This invention consists of improvements relating to pumps for inflating the
pneumatic tyres of cycle and other vehicle wheels.
My object is to dispense with an independent inflator such as is now in ordinary
use, by forming the pump barrel or cylinder as a part of the vehicle framing, and
thus to construct a simple pump with a long piston or plunger stroke, that shall be
always secure in a position adapted for convenient and effective operation when
required.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to;-
Figure 1 is an elevatiou of a bicycle fitted with my improved inflator.
Figure 2 is a sectional view of the inflator to a larger scale.
In the application of my invention to the construction of a pump or inflator for
a cycle of the safety type, I preferably adapt the diagonal tube stay A to serve as
the barrel or cylinder, the plunger B being fitted within this tube. The plunger
rod C extends through the upper side of the tubular saddle pin at its junction with
the diagonal stay, a suitable cap or gland being provided to prevent vibration of
the rod during the propulsion of the cycle. A convenient handle such as D is
fitted to the outer extremity of the rod, immediately beneath the saddle, and to
permit of access to the same, and to allow of the reciprocation of the pump plunger
I provide flaps or a detachable piece or a suitable aperture in the saddle seating.
The air is admitted to the barrel or cylinder through apertures in the cap or gland,
and is discharged on the instroke of the plunger through a connection at the lower
end of the barrel and in such a position that the flexible connecting tube can be
attached to the tyre valve of either the front or rear wheel, as illustrated at
Figure 1. The non-return valve E is fitted as illustrated or in some other suitable
position.
The connecting tube is made of sufficient length for attachment to a pneumatic
saddle when such is employed, in order that such saddle may be inflated from the
fixed tyre pump.
I sometimes employ a detachable or hinged handle for operating the pump,
fixing it upon the outer extremity of the plunger rod which I cause to project
through a ventilation hole or other aperture in the saddle when the pump is to be
worked.
In the case of an L shaped saddle pin the saddle will be thrown sufficiently
forward to permit the rod to be reciprocated clear of the rear end of the saine.
Instead of fitting the pump plunger within the diagonal stay as hereinbefore
described, I sometimes fit it within another. portion of the tubular framing of the
cycle or in a separate tube rigidly fixed to the framing.
When constructing a pump for inflating the pneumatic tyres of a brougham,
auto-car, or other like vehicle, I form the barrel or cylinder from a part of the
under-framing, or from a tube rigidly fixed or secured to the same, and preferably
in such convenient position as to make it available for simultaneously inflating all
the tyres of the vehicle. I preferably so, arrange the plunger and the valves of the
pump for such a service, as to provide a double action, the air being drawn into
and discharged from the barrel at each end, on opposite sides of the plunger.
When applying my invention to a motor car I sometimes arrange for the

page_text: mechanical reciprocation of the plunger by suitable mechanism connected with the
motor.
I do not limit the application of my invention to a cycle or other vehicle of any
particular type or pattern, but adapt the same, with such modifications as may be
necessary, to the various forms of road vehicles having wheels fitted with pneumatic
tyres.
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. The use of the diagonal stay or other tubular part of a cycle or other vehicle
framing as a pump or inflator barrel, substantially as described.
2. A pump or inflator for cycles and other vehicles having its barrel formed
from a part of the framing or from a tube secured to the same and arranged
substantially as and for the purposes described.
Dated this 5th day of December 1896.
