PROVISIONAL SPECIFICATION.
Improved Means for Carrying Inflators on Cycles.
We, HARRY DE MONTFORT WELLBORNE, of 17, Duke Street, Southwark, S.E.,
Solicitor, and ALFRED EDWARD HALL, of 3, The Exchange, High Street, Clapham,
S.W., Manufacturer, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to improved means of carrying inflators on cycles, of that
kind in which the inflator is held between spring pressed and fixed centres engaging
in the opposite ends of the handle and barrel of the inflator, the centres being carried
by brackets attached to the frame of the machine by bands or clips.
Heretofore the movable centre, the spring, the cylinder enclosing the spring and
in which the guide stem of the centre is fitted to slide, and the band clip have usually
been made of separate parts and the object of this invention is to simplify and cheapen
the construction of such inflator carriers by making the centre (particularly the spring
centre) and its supporting bracket in one piece with the band clip by coiling a ribbon
of spring metal in the form of a volute or coned spiral connected by a short inter-
mediate straight piece to form the offset or arm of the bracket to a curved portion to
form the band clip, which terminates in a straight portion or ear that is united to the
intermediate part forming the bracket arm, by clamping cheeks and a screw whereby
the band is tightly secured around the tube of the frame with the bracket arm and
spring centre in proper position for holding the inflator. The volute spring centre
may be partially enclosed in a casing or cap of stamped metal to exclude wet and its
point may be sheathed to adapt it to fit in the hole in the end of the inflator, or it
may carry a cup socket to receive the end of the inflator. The other centre may be
made in the same way, but as this does not require to be yielding it may be made
solid by running molten metal into the coned spiral or volute portion, or the latter
may be encased so as to form a rigid support.
Improved Means for carrying Innators on Cycles.
We, HARRY DE MONTFORT WELLBORNE, of 17, Duke Street, Southwark, S.E.,
Solicitor, and ALFRED EDWARD HALL, of 3, The Exchange, High Street, Clapham,
S.W., 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 :-
This invention relates to improved means of carrying inflators on cycles, of that

page_text: kind in which the inflator is held between spring-pressed and fixed centres engaging
in the opposite ends of the handle and barrel of the inflator, the centres being
carried by brackets attached to the frame of the machine by bands or clips.
Heretofore the movable centre, the spring, the cylinder enclosing the spring and in
which the guide stem of the centre is fitted to slide, and the band clip have usually
been made of separate parts, and the object of this invention is to simplify and
cheapen the construction of such inflator carriers by making each centre (whether
fixed or movable) in one piece with the corresponding band clip, the whole being
formed in each case out of a single strip of ribbon steel.
Reference is to be had to the accompanying drawings forming part of this
Specification wherein Figure 1 is a side view of a pair of combined centres and clips
constructed according to this invention, applied to a cycle frame, the inflator itself
being shewn by dotted lines. Figure 2 is. an end view of the combined spring centre
and clip and Figure 3 is a perspective view of the same, the clamping bolt being
omitted and the spring portion uncoiled. Figure 4 shews the strip from which the
combined fixed centre and clip is formed, developed in the flat.
The combined spring centre and clip A is composed of a ribbon of spring steel
coiled at one end in the form of a volute or coned spiral a which is connected with
the central portion forming the circular band clip b by a short straight piece c, the
band clip 6 being connected on the other hand, by a second and similar straight.
piece d, with a circularly bent portion e which closely encircles the base of the
spiral, and has its extremity flattened out to form a third straight portion f. The
various parts of the strip are so proportioned that when bent up as described, they
occupy substantially the relative positions indicated in the perspective view Figure 3
(except that in this figure the spiral a is shewn as uncoiled from within the
encircling band e) with the three straight portions c, d, f facing each other.
straight portions being securely held flat against one another, a hole g is punched
through them all to receive a bolt h whereby the parts are held in their proper relative
positions and the band tightly clamped around the tube t of the cycle frame with
the bracket arm formed by the straight portions b, d, f holding the spring centre a
in position for supporting the inflator x as shewn in Figure 1.
These
That portion of the strip which forms the coned spiral a is tapered in width as
indicated in Figure 3 so as to render the point i of the spring centre more elastic, and
the spiral is made to receive its conical form in the process of coiling.
The combined fixed centre and band clip K may be made as above described, the
centre being rendered rigid by running molten metal into the clip formed by the
interior of the coned spiral or volute portion. Preferably however the combined
centre and clip is formed from a blank of ribbon steel as shewn in Figure 4 bent and
stamped up to the shape indicated in Figure 1. In this arrangement the rigid coned
centre is constituted by (preferably) three triangular tongues k¹³ projecting
laterally from the strip towards one end as in Figure 4. The strip is bent up as
follows: That portion of the strip which carries the triangular tongues is circularly
bent to form the cylindrical base of the coned centre, a short straight portion m
being left at one end of the strip beyond the tongues, and a similar straight portion n
connecting the part with the circularly bent band clip portion o beyond which the
strip terminates in a third short straight portion p. When thus bent up the three
straight portions m, n, p face each other, with the short end m placed between n and p;
and these being held securely flat against one another, a hole q is punched through
them all to receive the clamping bolt and the tongues k¹³ are brought by
stamping in suitable dies to the form of the complete cone shewn in Figure 1.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A carrier for use in supporting inflators on cycles, composed of a single piece of
ribbon steel bent up to form a coned centre adapted to engage with the end of the

page_text: inflator and a band adapted to be clamped around a member of the frame, sub-
stantially as specified.
2. An inflator carrier for cycles composed of a single strip of spring steel
coiled to form a coned spiral spring centre adapted to engage with the end of the inflator
and a band adapted to encircle and be clamped upon a member of the frame, sub-
stantially as specified.
