Improvements in or relating to Cycle Pumps or Inflators and the like.
I, HARRY DORNING BAILEY, of "Norbury," Grove Park Gardens, Chiswick,
in the County of Middlesex, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement
My invention relates to cycle pumps or inflators, and the like, and has for its
object to provide an attachment whereby an ordinary cycle pump adapted for being
called on a bicycle can be very easily converted into a foot pump which can be
held firmly by the foot of the user, while the handle is worked by the hand.
Hitherto foot pumps have been so constructed as to be unsuitable for carrying
on a cycle, because the stirrup or portion which is held by the foot of the user
has been made heavy, and of such shape as to prevent the pump from being secured
to the tubes of the machine, or when the pump 18 so secured the starrup portion
projects so as to interfere with the movements and comfort of the rider.
According to my invention I provide means whereby an ordinary inflator such
as 18 carried by most cyclists can be readily converted into a foot pump, and in
order that my invention may be readily understood I will now proceed to describe
the accompanying drawings in which
Figure 1 is a perspective view showing the lower portion of an inflator fitted
with my improved device,
Figure 2 is an elevation illustrating a modification of the same.
Referring now to Figure 1, the barrel of the inflator is indicated at A and the
nozzle which projects from the end of the pump has secured to it by means of a
nut B an india-rubber or other flexible tube B¹, the other end of which is provided
with means such as the nozzle B for securing it to the tyre valve.
For converting such a pump into a foot pump, I provide an L-piece shown at C,
the upper limb C¹ of which is bent at right angles and provided with an orifice
through which the pump nozzle passes so as to be tightly clamped between the
nut B and the bottom of the pump I sometimes provide a lock nut secured to
the L-piece by a chain and interposed between the part C and the nut B
lower or horizontal part C of the L-piece, is intended to be pressed on the ground
by the foot of the operator when the pump 18 being used
The
In Figure 2 my invention 18 shown applied to a pump which 18 provided with a
nozzle at the side of the barrel instead of at the bottom; in this case the vertical
portion of the L-piece is provided with an orifice through which the nozzle passes,
and 18 secured by means of the nut B on the end of the connecting tube in the
same manner as herein above described with reference to Figure 1.
The attachment can obviously be arranged so that the part projects underneath
the pump barrel or is turned the other way, or the L-piece may be turned the
other way round so that the foot of the operator is under the nozzle of the pump.
My improved device 18 very easily and quickly attached to an ordinary inflator
and does not increase the weight of the same to any great extent, and it will be
seen from the drawings that the presence of the attachment does not interfere
with the securing of the pump to the cycle frame Usually, however, the india-
rubber tube B¹ and its accompanying nut B are removed when the inflator is

page_text: being carried, in which case the L-piece C can be carried in the wallet or in the
pocket of the cyclist
My attachment may be made of any suitable material, and I do not restrict
myself to the precise shape shewn in the diawings, as obviously variations in
detail may be made which fall within the scope of my invention
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
olaim 18:-
pumps
