PROVISIONAL SPECIFICATION.
Improvements in the Fittings of Pneumatic Tyre Inflators.
I, CHARLES THOMAS BROCK SANGSTER, Works Manager to the Cycle Components
Manufacturing Company Limited, of Bournbrook, near the City of Birmingham,
do hereby declare the nature of this invention to be as follows:-
This invention relates to the fittings of pneumatic tyre inflators, and consists,
in the one part, in a rest attachment for the point cup end of the cylinder in order
to relieve the hand from the strain of supporting the pump when in use, and in
another part, the making of an air-tight attachment between the metallic adapter
and flexible connection without wiring.
In carrying out my improvements, I take an ordinary pump having a point cup
at its forward end, upon which point the eye of a crank-shaped support with a
turned up or hooked end takes and is fitted and is there secured by a lock nut
taking over the outside screwed part of the point, whilst the adapter takes within
the interiorly screwed bore of the same. Thus the support is made of the figure of
an angle piece, with the eye of the shank end, which lies in the plane of the cap,
taking over the point, whilst the other part runs parallel with and lies snug against
the side of the barrel and the rear end is bent into a hook or like shape adapted
to engage with or take over a wheel rim and form a rest for the wheel rim when
operated.
The point may consist of a headed screw passing through a hole in the
cap from
the inside and being there brazed or soldered or affixed by spinning or spreading
the metal of a shoulder of the shank outwards which extends forwardly through the
hole in the cap.
In carrying out the second part of my invention, the attachment consists of a
union ring or tie-band, with a flat ear formed from. out of the walls of the rim by
pinching up a portion of the same. The end of the flexible connection is passed over
the tail of the adapter and then by imbedding or pressing in the ear flush with the
outer circumference of the ring, the rubber of the connection is contracted on the
tail end of the said adapter. By thus binding the adapter to the connection by a
crimpled in or corrugated part, the possibility of any escape of air is minimised.
Dated this 18th day of June 1897.

Improvements in the Fittings of Pneumatic Tyre Inflators.
I, CHARLES THOMAS BROCK SANGSTER, Works Manager to the Cycle Components
Manufacturing Company Limited,. of Bournbrook, near the City of Birmingham,
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 the fittings of pneumatic tyre inflators, and consists,
in the one part, in a rest attachment for the point cup end of the cylinder in order
to relieve the hand from the strain of supporting the pump when in use, and in
another part, in making an air-tight attachment between the metallic adapter and
flexible connection of, a pump without wiring.
Figure 1 of the accompanying drawings represents an elevation of a pneumatic
tyre inflator fitted with a rest attachment constructed and applied to the cylinder
in accordance with my invention.

Figure 2 is another view of the said inflator, showing the rest attachment in plan.
Figure 3 is a section upon the dotted line, Figure 2, looking towards the point
.end of the cylinder.
Figure 4-is-a-section upon-the-dotted line, Figure.2.
Figure 5 is a front elevation, of the rest attachment separately,
is a vertical section of the same, upon the dotted line 2.
and Figure 6
Figure 7 represents the attachment, with its securing nut and the point end of
the inflator, separately.
Figure 8 is a like view of the inflator end as in Figure 8, but looking at the
same in another direction, in order to show the flat on one side of the point screw.
The same letters of reference indicate corresponding parts in the aforesaid
Figures 1 to 8, of the drawings.
In carrying out this part of my improvements, I take an ordinary pump a, having
screwed point a', at its forward end, upon which point the eye b', of a crank-
shaped support b, with a turned up or hooked end 63, takes or is fitted and is there
secured by a lock nut c, taking over the outside screwed part of the point, whilst
the adapter d, of the flexible connection or pipe e, takes onto the extending end of
the same.
Thus the support is made of the figure of an angle-piece, with the
eye b, of the shank end 63, which lies in the same plane as the front end of the
cylinder, taking over the point, whilst the other part runs parallel with and lies
snug against the side of the barrel and the rear end is bent into a hook or like
shape adapted to engage with or take over a wheel rim and form a rest for the wheel
rim when operated or it may consist of a grip to enable the fingers of the hand
taking a better hold upon the body of the pump.
The point a, may consist of a beaded screw passing through a hole in the cap
from the inside and being there brazed or soldered or affixed by spinning or
spreading the metal of a shoulder of the shank outwards which extends forwardly
through the hole in the cap..

To prevent the rest attachment from turning or twisting when in use, the screw
point is made with a flat a, upon one side, thus making it somewhat of a D-section,
whilst the eye b', in the shank of the attachment is of a corresponding D-shape.
Figure 9 represents a side elevation of the point end of an inflator fitted with
adapter to which the flexible connection is attached by means in accordance with the
second part of my invention.
Figure 10 is a cross section upon the dotted line, Figure 9.
11 is a longitudinal coation and

page_text: Figure 12 represents a section of the tie band and flexible connection, before the
introduction of the latter onto the tail end of the adapter and the binding of the
parts together by the gathering in of the said band.
Figure 13 is a section of the tie band separately, and Figure 14 an elevation of
the adapter.
In carrying out this second part of my invention the attachment of the flexible
connection e, to the adapter d, is effected by a union ring or tie-band f, with an
internal ear f¹, formed from out of the walls of the same by pinching up a portion
of the metal. The end of the flexible connection is passed over the serrated tail,
of the adapter and then by imbedding or pressing in the ear flush with the inner
circumference of the ring, the rubber of the connection is gathered in or contracted
onto the said tail end. By thus binding the adapter to the connection by a
crimpled in or corrugated part, the possibility of any escape of air is minimised.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I déclare that what I
claim is:
First: In pneumatic tyre inflators, providing the screw point end of the same
with a supplementary rest or grip attachment, consisting of an eyed shank, passed
over the said point end and being there secured by a nut or equivalent, and having
a returned hook end, substantially as described and set forth.
Secondly: In rest or grip attachments for pneumatic tyre inflators, preventing
the same from rotating when in position, by providing them with a D-shaped or
equivalent eye taking upon a flatted screw or point of the inflator substantially as
described and set forth.
Thirdly: In the flexible connections of pneumatic tyre inflators and air pumps,
providing the ends of the same with confining bands or rings, substantially as and
for the purpose described and set forth.
Fourthly: In the flexible connections of pneumatic tyre inflators and air pumps,
providing the ends of the same with confining bands or rings having a crimped
or corrugated part, which is closed or gathered in around the said ends after the
tail ends of the adapter fittings have been forced home, substantially as and for
the purpose as described and set forth.
