Improvements IH
I, HARRY LUCAS, of Tom Bowling Lamp Works, Little King Street, in the
City of Birmingham, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to the carriers or holders for pneumatic tyre inflators or
pumps, and my object is to permit the inflator or pump to be readily attached or
detached from the machine; and at the same time to produce an absolutely secure
fastening.
My invention consists in a flat spring clip with a hinging fastening device.
In one method of carrying my invention into effect, a strip of sheet steel is bent
so that one half of it partially wraps round a convenient part of the tubular cycle
frame, a distance equal to about two thirds of the circumference. 'It is then bent
back through a short curve of small radius and is again bent forward to a diameter
equal to that of the inflator or pump barrel, and a distance equal to about two
thirds of the pump barrel circumference. This strip then forms two short partial
cylinders parallel with one another and connected with each other by the short
curved portion. The two ends of the strip are thus opposite to one another and in
the same plane. That end of the strip on the cycle frame is turned over to form a
hinge. The end of the strip on the pump barrel is turned up in the direction away
from the cycle tube to form a semi-circular lip. A strong wire catch piece, made
preferably of rectangular form, with an extension for a finger grip, is so arranged
that the bottom portion of the rectangle swivels on in the hinge, while the top
portion fits over the semi-circular lip. The extension for the finger grip is formed
on the top portion of the wire catch piece. When the catch is off the semi-circular
lip, the two partial cylinders spring away slightly from one another. The short
connection curve of the two partial cylinders being elastic owing to its shape,
permits them to be spring together through a short distance sufficient to put the
connecting catch on the semi-circular lip.
The partial cylinder for the pump barrel is made an easy fit when the catch is
off, and the swinging of these two partial cylinders together slightly lessens their.
internal diameter and thus locks or grips the pump barrel firmly in its place, at the
same time the reaction of the spring connecting curve firmly locks or grips the
semi-circular lip in the top of the wire catch.
One characteristic feature of my invention consists in the hinging catch piece
holding together the two portions of the clip, and this catch piece may be made of
other than wire construction without departing from the invention.
t
In another modification of my invention I hinge to one part of my spring clip
two levers or bars and these carry at the other end a swivelling piece arranged to
form a combined grip 'piece and catch. The interior edge is arranged when turned
flat or thereby to pass into the bent portion of the spring clip' and on pulling up the
grip piece the spring clip is forced firmly down while the swivelling grip piece by
toggle action brings the centres in line with its inner end and so remains fixed
until the grip end is moved outwards.
Dated this 9th day of November 1894.

I, HARRY LUCAS, of Tom Bowling Lamp Works, Little King Street, in the
City of Birmingham, Manufacturer, 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 :-
My invention relates to carriers or holders for pneumatic tyre inflators or
pumps, and my object is to permit the inflator or pump to be readily attached or
detached from the machine, and at the same time to produce an absolutely secure
fastening.
.
My invention consists in a flat spring clip with a hinging fastening device.
In one method of carrying my invention into effect a strip of sheet steel is bent
so that one half of it partially wraps round a convenient part of the tubular cycle
frame, preferably a distance equal to about two thirds of the circumference. The
strip is then bent back through a short curve of small radius and is again bent
forward to a diameter equal to that of the inflator or pump barrel, and a distance
equal to about two thirds of the pump barrel circumference. The strip thus forms
two short partial cylinders parallel with each other and connected by the short
curved portion, and having its ends opposite to each other, the end of the strip on
the cycle frame being turned or bent over to form a hinge while the opposite end,
on the pump barrel, is turned up to form a semi-circular or other shaped lip. A
strong wire or other catch piece, made preferably of a rectangular form with an
extension for a finger grip, is so arranged that one side or portion of the rectangle
swivels in the hinge formed by the end of the strip while the opposite side fits over
the lip. When the catch is off the semicircular lip, the two partial cylinders spring
away slightly from one other. The short connection curve of the two partial
cylinders being elastic, permits them to be sprung together through a short
distance sufficient to enable the connecting catch to be slipped over the semi-
circular lip.
The partial cylinder for the pump barrel is made an easy fit when the catch is off,
but the drawing together of the two partial cylinders by means of the catch
slightly lessens their internal diameter and thus locks or grips the pump barrel
firmly in position, and at the same time the reaction of the spring clip secures the
lip end in the catch piece.
One characteristic feature of my invention consists in the hinging catch piece
holding together the two portions or ends of the clip, and this catch piece may be
of wire or such other suitable construction as may be desired.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to ;-
Figure 1 is an elevation of a cycle frame having the pump or inflator attached
thereto by means of a pair of my improved spring attachments.
Figures 2 and 3 are front and side elevations respectively, representing to a
larger scale my spring attachment with catch piece fitted thereto.
The same reference letters in the different views indicate the same parts.
The pump or inflator A Figure 1 when not in use is secured by means of the
attachments B preferably two in number to the tube C or other convenient part of
the cycle frame. The attachments each consist of a double clip formed from one
strip of elastic metal preferably sheet steel bent to a shape or configuration such
as shown at Figures 2 and 3, the curved portion D forming the connection between
the short partial cylinders or clips E and F on one side, whilst the ends of the
strips are secured by means of the catch piece G. The end H of the double
spring clip is turned or bent over on one side or end of the catch piece G thus
forming a hinge connection as illustrated at Figures 2 and 3; the opposite end is

page_text: turned up to form a lip or projection for the engagement of the catch piece. The
outer side or free end of the catch piece is provided with a finger grip such as G¹
for convenience in attachment and detachment.
When the catch piece F is detached the part E of the spring clip can be readily
slipped over the tube or other convenient part of the cycle frame, and the pump or
inflator can be inserted within the part F. On pressing the free end of the catch
piece over the lip or projection J on the end of the spring clip the internal
diameters of the parts E & F are reduced and thus the part E is caused to grip the
tube C and the part F to close on to and grip the pump or inflator A. The inflator
is thus effectually secured to the tube C or to any other convenient and suitable
part of the cycle frame.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.-
1. The method of securing a pump or inflator to a cycle frame by means of
spring clips having hinged fastening devices substantially as herein described.
2. The construction of a double spring clip from a flat strip of steel or elastic
metal bent or shaped to embrace the cycle frame and the pump or inflator to be
attached thereto, and having its ends secured by means of a hinged catch piece
substantially as hereinbefore described, and as illustrated in the accompanying
drawings.
3. The improved spring clip with hinged catch piece substantially as and for the
purposes herein described.
