COMPLETE SPECIFICATION.
Improvements in Pumps for Inflating the Tires of Velocipedes and
the like.
We, ERNEST BROWN, Merchant, of 26, 28, and 30, Great Eastern Street, in the
County of London, and CHARLES BRITTON, Manufacturer, of 16, Theodor Street,
Birmingham, in the County of Warwick, 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 relates to improvements in pumps for inflating the tires of
velocipedes and the like and has for its object to adapt the usual tubular pump for
use as a foot-pump without interfering with the facility which the tubular pumps
affords for attaching it to the frame of the velocipede. In accordance with this
invention the pump is constructed as shewn in the accompanying drawings in
which:
Fig. 1, shews a plan-view of so much of the pump as is necessary in order to
illustrate this invention.
Fig. 2, is an elevation corresponding with Fig. 1, similar letters of reference
indicating the same parts in both figures.
In these figures, A. is the body or barrel of the pump and B the nozzle thereon
which serves as usual to connect it with the tire or the like. The parts for com-
pressing the air being of the usual construction call for no description. At C C
the bands or arms D D are so attached to the body of the pump (say by screws as
shewn) as to permit rotation of the arms, the joints being made rather "stiff SO
that the arms will readily retain the position shewn in Fig. 1, or that represented
in Fig. 2. E is a curved end piece connecting the arms I) D, and jointed thereto
at dd, also by a stiff joint.
"
When this pump is to be carried on a velocipede or otherwise, the arms D D
and the end-piece E are turned flat against the body as appears from the full lines
in Fig. 2, but when the pump is to operate the arms and end-piece are turned
Cownward or outward as seen in Fig. 1, and in dotted lines in Fig. 2, so as to afford
a bearing surface for the operator's foot and giving him much greater ipower over
the pump.
In conclusion we wish to state that we are well aware that various means have
ere now been proposed for attaining the objects which we have in view with our
present invention, our construction however is particularly advantageous because,
whilst affording a large bearing surface for the foot during the operation of pump-
ing, it has no projecting parts that may prove inconvenient when the pump is
not in use, and the whole construction is extremely cheap, durable and effective.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
In a pump for inflating the tires of velocipedes and the like, the combination

with the pump body of the arms D D, jointed thereto by a
nected by a curved-piece E, all constructed combined and operating as set forth
and as illustrated in the accompanying drawings.
