Improvements in and relating to Inflators for Pneumatic Tyres.
We RICHARD LEE PHILPOT, of Loch View, Burnside, Rutherglen N.B.,
Manager of Works, and HENRY BIRCHALL CLAYSON, of 22 Victoria Street
Bristol, in the County of Gloucester, Manager of Depôt, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to an attachment for application to inflators or pumpз used
for inflating the pneumatic tyres of the wheels of velocipedes and similar vehicles,
the object being to facilitate the inflation of the tyre and to relieve the hand or
hands of the operator from excessive strain.
According to our invention we form on or attach to the end of the piston of an
inflator or pump a crutch-shaped bracket, the crutch being transverse to the length
of the piston. This crutch-shape bracket is made of such a size and section that
it will embrace either the fork carrying the steering wheel of a cycle, or one of
the members of the main frame thereof. As a modification a double crutch may
be formed on or attached to each piston though we prefer to use but one such
crutch. To use this device the wheel is turned round until the inflation valve of
the tyre is in close proximity to one of the members of the fork or frame carrying
the said wheel. The flexible nozzle of the inflator or pump is then attached to the
valve and the crutch-shaped bracket on the piston is engaged with the adjacent
member of the fork or frame, to which it is held by the one hand of the operator,
merely to keep it engaged therewith, the said member of the frame thereby taking
all the strain off the hand of the operator.
As a modification the engaging bracket on the piston of the inflator or pump
may be fitted with some sort of clamping device so that it can be clamped or fixed
to the member of the fork or frame of the machine.

Improvements in and relating to Inflators for Pneumatic Tyres.
We, RICHARD LEE PHILPOT, of Loch View, Burnside, Rutherglen N.B.,
Manager of Works, and HENRY BIRCHALL CLAYSON, of Bristol, in the County
of Gloucester, Manager of Depôt, 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 an attachment for application to inflators or pumps used
for inflating the pneumatic tyres of the wheels of velocipedes and similar vehicles,
the object being to facilitate the inflation of the tyre and to relieve the hand or
hands of the operator from excessive strain.
According to our invention we form on or attach to the end of the piston rod of
an inflator or pump a crutch-shaped bracket, the crutch being transverse to the
length of the piston rod. This crutch-shape bracket is made of such a size and
section that it will embrace one of the members of the fork or frame of the cycle.
As a modification a double crutch may be formed on or attached to the piston rod
though we prefer to use but one such crutch. To use this device the wheel is
turned round until the inflation valve of the tyre is in close proximity to one of the

page_text: members of the fork or frame carrying the said wheel. The flexible nozzle of the
inflator or pump is then attached to the valve and the crutch-shaped bracket on
the piston rod is engaged with the adjacent member of the fork or frame to which
it is held by the one hand of the operator merely to keep it engaged therewith,
the said member of the frame thereby taking all the strain off the hand of the
operator.
As a modification the engaging bracket on the piston rod of the inflator or pump
may be fitted with a clamping device so that it can be clamped or fixed to the
member of the fork or frame of the machine.
and
In the accompanying drawing which illustrates our invention,
Figure 1 is a view of one type of inflator or pump fitted with our invention,
Figure 2 is another view of the crutch bracket.
Figure 3 is a view of another type of inflator or pump fitted with a crutch
bracket of another shape, and
Figure 4 is a broken view showing a crutch bracket fitted with a clamping
device.
Throughout the views similar parts are marked with like letters of reference.
When the inflator or pump is of the type in which the cylinder is used as the
handle as shown by Figure 1, the crutch bracket A is formed on or attached to the
piston rod B, but when the inflator or pump is of the type in which the piston rod
is used as the handle as shown by Figure 3, the crutch bracket A is formed on or
fixed to the end of the cylinder C.
The crutch bracket A is made of a suitable shape to embrace and engage with
one of the members of the fork or frame of the machine as shown by Figure 1,
but as a modification it may be made of a suitable shape to fit over and engage with
the rim or tyre of the wheel as shown by Figure 4.
If desired a double crutch bracket may be used as shown by dotted lines in
Figure 1.
As a modification the crutch bracket A may be made to clamp on to one of the
members of the fork or frame of the machine, a convenient method of doing this is
illustrated by Figure 4, one, or both of the arms of the crutch bracket being hinged
to the other part thereof, and a clamping bolt being passed through the free ends
of the arms of the bracket to draw them together.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction herein before described and illustrated by the
accompanying drawing, but that we hold ourselves at liberty to make such changes
and alterations as fairly fall within the spirit and scope of our invention.
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 improvement in inflators or pumps for inflating pneumatic tyres,
substantially as hereinbefore described and illustrated by the accompanying
drawing.
2. In an inflator or pump, the combination with the piston rod thereof, of a crutch
bracket, as set forth.
3. In an inflator or pump, the combination with the cylinder thereof, of a crutch
bracket, as set forth.
4. In an inflator or pump, the use of a crutch bracket fitted with a clamping
device, as and for the purpose set forth.
