A New or Improved Means for Attaching Air-pumps or Inflators to
Velocipedes.
We, RICHARD HENRY LEA, and GRAHAM INGLESBY FRANCIS, both of 11, Lower
Ford Street, Coventry, in the County of Warwick, Cycle Manufacturers, 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 refers to a new or improved means for attaching air-pumps or
inflators to velocipedes.
Hitherto a great variety of clips have been used for attaching air pumps or
inflators to velocipedes, and such have varied in the matter of material as well as
in design, steel, celluloid, rubber and leather, all having been proposed or tried,
both separately and in combination with each other. In all the different arrange-
ments however, of which we are aware, the clips are made to surround or partially
surround the exterior or barrel part of the pump, and when as is usually the case,
the pump is attached to the diagonal tube of the cycle, the clips are commonly
dependent for their effectiveness, on the surface friction engendered by the
elasticity of the material employed.
No really satisfactory results have yet been obtained by any of the various
methods referred to, and amongst their disadvantages may be enumerated the
following:
1. Liability to damage the enamel of the Velocipede.
2. Extreme ease with which they are displaced in relation to the velocipede
frame, and consequently
3. The general slovenliness of appearance.
4. Difficulty of removing and replacing pump when required for use.
5. Ease with which one clip is displaced in relation to the other, thus allowing
movement of the piston in the pump, and consequent rattle.
6. Perishability of rubber, especially when in tension.
7. Danger due to pump becoming wholly or partially detached when travelling
at speed.
«
Having thus referred to some of the principal imperfections of the existing
clips," we will now proceed to describe how we have overcome the same according
to our invention, and referring to the accompanying drawings which shew, by
way of example, a convenient construction by which the same may be carried into
effect.
Fig. 1 is a side elevation of a part of a bicycle frame of ordinary construction,
shewing the air pump attachment, the said pump being in longitudinal section,
Fig. 2 shews a pump of somewhat different construction, and is illustrated in order
to shew how same can be held by our attachment devices. Fig. 3 shews one of
the clips in elevation the same being provided with a flanged cup or ferrule, and
drawn to a larger scale than the previous figures in order to give greater details.
Figs. 4 shew an end view and section of a flanged cup or ferrule detached. Fig. 5
is a sectional elevation shewing one of the clips fitted with a spring actuated

with means such as a plunger or bolt, adapted to take into and against the pump

inflator is held and end pressure applied thereto, essentially composed of a

spring action to take into and against the other end of the pump, substantially
as described and illustrated with reference to the accompanying drawings.
