Improvements in Attaching Inflating Pumps to Cycles.
I, GEORGE FREDERICK REDFERN, of the Firm of G. F. Redfern & Co., The
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
Patent Agents, do hereby declare the nature of this invention (a communication
to me by Robert Reid, of A'Becket Street, Melbourne, in the Colony of Victoria,
Engineer), to be as follows:-
This invention relates to improvements in attaching inflating pumps to cycles.
According to my invention I fix to one of the bars of the cycle frame two
projecting lugs or plates between which the pump is to be held, the said lugs
or plates being cup shaped or otherwise suitably formed so as to engage with
the ends of the pump.
To permit of introducing the pump between these lugs one of the said lugs is
formed so that a part thereof may be moved longitudinally relatively with the
other part, against the pressure of a spring; or instead of making the lug with a
spring adapted to yield, the spring may be arranged in the pump itself so that the
latter may be compressed or shortened slightly to permit of introducing it between
the said lugs.
Dated the 5th day of August 1898.

COMPLETE SPECIFICATION (AMENDED).
Improvements in Attaching Inflating Pumps to Cycles.
I, GEORGE FREDERICK REDFERN, of the Firm of G. F. Redfern & Co., The
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
5 Patent Agents, do hereby declare the nature of this invention (a communication
to me by Robert Reid, of A'Becket Street, Melbourne, in the Colony of Victoria,
[Price 8d.1

page_text: Engineer), and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement;-
This invention relates to improvements in attaching inflating pumps to cycles.
According to the invention I fix to one of the tubes or bars of the cycle frame two
projecting lugs or plates between which the pump is to be held, the said lugs
or plates being cup shaped or otherwise suitably formed so as to engage with
the ends of the pump.
To permit of introducing the pump between these lugs one of the said lugs is
formed so that a part thereof may be moved longitudinally relatively with the
other part against the pressure of a spring.
In the accompanying drawing,
Figure 1 is a sectional elevation showing a pump secured to a stay of a bicycle
frame according to my invention.
Figure 2 is a view shewing one of the cup-shaped lugs in section:
Figure 3 is an end view of the said lug; and,
Figures and 5 are views similar to Figures 2 and 3 respectively illustrating
the spring lug.
Figure 1 is drawn to a smaller scale than Figures 2 to 5.
A is the stay or bar of the cycle frame and B is the pump which may be of
any suitable construction. a is the lug which is designed to receive the nozzle
end of the pump, the said lug a being cup-shaped and preferably stamped from a
piece of sheet metal in such a manner as to be formed with a curved seat b
designed to be applied against the tube A and with an eye c through which passes
the clamp d by means of which it is secured to the said tube A. The cup-shaped
luga is provided with a central hole a adapted to receive the screw nipple B
of the pump as clearly shewn in Figure 1.
c is the other lug, the said lug being also formed cup-shaped or conical so as
to receive the handle end 132 of the pump as shewn in Figure 1. The said lug e
is provided or formed with a clamp f by means of which it is secured to the
stay A.
As above described one of the lugs is to be provided with a spring arrangement
to allow of the necessary movement for inserting the pump between the cup-shaped
lugs which are secured to the stay A in such a position that the distance between
their inside centres is equal to the normal length of the pump when collapsed
or closed.
As shewn in Figures 4 and 5 the lug e is formed with a cone or cup the base
of which fits the inside of the said lug and the apex of which is provided with a
pin h which extends back through a hole in the apex of the lug e, which acts
as a guide; the cup is supported in its outermost position, that is to say, in the
position wherein its base is in the same plane as the base of the conical lug e
by a spring but which can be slid into the said lug e against the action of the
spring when the pump B is being inserted. The outer end of the pin h¹ is
screw-threaded and is provided with a nut h³ so that the tension of the spring i
can be adjusted.
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:
1. An attachment for securing pumps to cycles comprising two lugs secured to
a stay or bar of the cycle frame and adapted to embrace the ends of the pump
substantially as hereinbefore described.
2. The combination with a pump of two cup-shaped lugs secured to a stay of a
cycle frame and of means whereby a part of one lug can be moved longitudinally
relatively with the other, to allow of the introduction of the pump, substantially
as herein before described.
3. An attachment for securing inflating pumps to cycles comprising the lug a

page_text: adapted to be clamped to the said stay and having a hole a¹ for receiving the
pump nipple, and the lug e having the spring cup for receiving the handle
of the pump, substantially as herein before described and illustrated.
