Improvements relating to Means for Attaching a Tyre Inflator
to a Cycle.
I, GEORGE WILTSHIRE, of 71, Waverley Road, Small Heath, Birmingham,
Mechanician, do hereby declare the nature of this invention to be as follows;-
The tyre inflator is located and carried in the hollow stem of the handle bar,
and in the drop tube or steering tube of the cycle head. The handle bar is,
like the latest pattern handle bars, carried by a lug formed on the front side of
the handle bar stem, and the upper end of this stem, is left open, so that the
inflator may be inserted and passed down the said stem, and steering tube. The
inflator is secured to the stem of the handle bar by a screwed cap, the said cap
having a screw threaded central shank which is adapted to screw into the screwed
aperture in the inflator which receives the nozzle of the inflator when the latter
is put together for use. This cap may possess a female thread adapted to screw
on to a male thread formed on the upper extremity of the handle bar stem or the
male thread may be upon the cap and the female thread on the stem. The cap is
thus screwed into the pump by means of its screwed shank and is then screwed
into or on to the stem of the handle bar.
In order that the inflator may be prevented from rattling against the stem
of the handle bar, the said stem is provided with a spring device which
clasps the inflator. Such spring device is preferably formed of pen steel and may
consist of a ring attached to the lower end of the stem and provided with tongues
or prongs which are inclined towards the axis of the stem and project down-
wardly. In the act of passing down the stem, the inflator presses apart these
spring tongues, so that the tongues bear upon the inflator and hold it centrally
in the said stem. The ring of this spring device may be attached to the internal
side of the stem or to the external side of the stem, and in the latter case, a
seating is turned on the stem, which accomodates the ring without increasing
the diameter of the stem. The spring tongues may project upwardly in the handle
bar stem instead of downwardly as above described.

to a Cycle.
I, GEORGE WILTSHIRE, of 71, Waverley Road, Small Heath, Birmingham,
Mechanician, 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:-
The tyre inflator is located and carried in the hollow stem of the handle-bar
and in the drop-tube or steering tube of the cycle head. The handle-bar is by
preference carried by a lug formed on the front or rear side of the handle-bar
stem, and the upper end of this stem is left open so that the inflator may be
inserted and passed down the said stem and steering tube.
In the drawings hereto annexed, Figure 1 is a perspective view of a cycle
head and handle-bar, fitted with a tyre-inflator in accordance with my invention.
Figure 2 is a view of the inflator drawn to a larger scale.
The inflator is secured to the stem of the handle-bar by a screwed-cap b.
This cap posseses three screw threads, namely, two male threads c and d and
a female thread e. The part bearing the thread c is adapted to screw into the
open-end of the stem a. The part bearing the thread d is adapted to screw into
the usual screwed aperture in the end of the inflator. The female thread e
permits the cap to be screwed on to the air-delivery end g of the inflator The
Hexible connection of the inflator is attached to the cap b.
To secure the inflator in the cycle head as shewn in Figure 1, the part d of
the cap is screwed into the part f of the inflator, the flexible nozzle being
disposed inside the inflator as at present. The inflator is then passed down the
hollow cycle head and is secured therein by screwing the threaded part c of the
cap into the upper end of the stem a.
To detach the inflator for use, it is brought out of the head by unscrewing
the cap b from the stem a. The cap is then unscrewed from the part f, and its
female thread e is then screwed on to the air-delivery end g as shewn in dotted
lines in Figure 2. The inflator is then ready for use.
When the inflator is in the cycle-head its lower part i is prevented from
sinking by means of the raised beading which finds a bearing against the top
of the brazed-in portion of the handle-bar stem or other shoulder in the stem as
described in my Patent Specification No. 20976 of 1899.
In order that the inflator may be prevented from rattling within the cycle head,
the lower end of the handle bar stem may be provided with a spring device which
clasps the inflator. Such spring device is preferably formed of pen-steel and may
consist of a ling attached to the lower end of the stem and provided with tongues
or prongs which are inclined towards the axis of the stem and project down-
wardly. In the act of passing down the stem, the inflator presses apart these
spring tongues, so that the tongues bear upon the inflator and hold it centrally
in the said stem. The ring of this spring device may be attached to the internal
side of the stem, and in the latter case a seating is turned on the stem, which
accomodates the ring without increasing the diameter of the stem.
The spring
tongues may project upwardly in the handle-bar stem instead of downwardly as
above described.
Having now particularly described and ascertained the nature of my said 4
invention, and in what manner the same is to be performed I declare that what
I claim is
1 As a means of securing a tyre inflator to
excle the can ½ howing the

page_text: three screwed parts c, d, and e, each of said parts performing the function herein
ascribed to it.
2. The combination with the flexible end of a tyre inflator, of a cap (such
as b) having screw threaded parts by which the cap may support the inflator in
a cycle head or may be attached to the delivery end of said inflator as required,
and as herein described.
