Improvements in Apparatus for Inflating the Tyres of Bicycles,
Tricycles, Motor-cars, and the like.
ROBERT HILDICK, Commercial Traveller, 168, Brighton Road, Moseley, Birming-
ham, do hereby declare the nature of this invention to be as follows:-
This my invention relates to the means employed in the inflating, or forcing
wind or air into the Hallam tyres, usually called pneumatic tyres. The method
I adopt is by placing or fixing an air pump, on the valve of the wheel or wheels
of bicycles, tricycles, and the like, the said air pump is caused to work, by its
coming in contact, as the wheel revolves, with other portion or portions of the
machine, specially constructed for that purpose. Namely a projection, or pro-
jections, made of metal or other suitable material, fixed upon the forks, (by
preference inside the forks) or upon any other portion or portions of the cycle or
motor car, in such manner that the pump, by the revolution of the wheel, shall
be brought into contact with the said projection or projections, the concussion
serving to operate the pump.
I claim for my invention that it does away with the necssity of a loose air
pump.

I, ROBERT HILDICK, of 168, Brighton Road, Moseley, Birmingham, in the County
of Worcester, Commercial Traveller, 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 has for its object improvements in apparatus for inflating the
tyres of bicycles tricycles motor cars and the like, by which such tyres can be
inflated when required by the revolution of the wheel and can be brought into
operation without in any way interfering with the travel of the wheel by which
means in the case of a slight puncture the tyre is retained in an inflated condition.
My apparatus is very simple and can be attached to any existing wheel.
In order that my invention may be clearly understood and carried into effect
I have appended hereunto a sheet of drawings upon which I have shewn my inven-
Di Q77

page_text: tion applied to the front wheel of a safety bicycle and from which its application
to other pneumatic wheels will be readily understood.
Figure 1 is an elevation of the front wheel of a safety bicycle.
Figure 2 is a cross sectional elevation through Figure 1..
Figure 3 is a plan of part of the handle shewing one arrangement for fastening
the operating rod.
In carrying my invention into effect I mount the air pump A upon any suitable
support such as the plate a¹ and in such a position that it can readily be connected
to the ordinary valve by means of the short length of rubber tube a²
the pump A being preferably mounted to revolve in the socket so that the screw
nipple a can readily be screwed on to the valve Y while the plunger of the pump
is provided with the roller at.
The projection B which is eccentric in shape to the wheel is mounted to slide
upon the slide C fixed to the front fork Z of the machine and retained in its
actuating position by the rod 1 which passes up through the slot in the handle
bar where it is secured against the resistance of the spring 3 by the stud b².
The action of pumping is as follows as the wheel revolves the roller at at each
rotation is actuated by the projection B against the resistance of an internal
spring as in the pump A which action forces the air through the valve the spring a
causing the plunger to return to its normal position at each rotation but when
the action of puniping is not required the rod which is free to revolve in the
connection is simply turned so as to allow the stud 3 to pass through the
slot in the handle-bar D thus allowing the eccentric projection B to drop
clear of the course of the rotating roller at by which means the pump remains out
of action.
The same arrangement with a modified form of rods and levers may be applied
to the driving wheel or to the wheel of any kind of vehicle.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The rotating pump-A mounted on the wheel in combination with the sliding
projecting eccentric B thrown in and out of operation substantially as and for
the purpose herein set forth and illustrated.
