Improvements in and relating to Inflators for. Pneumatic Tyres and
Means of Carrying the same.
I, WILLIAM HANLON, M.A., of The Rectory, Innishannon, Co. Cork, Ireland,
Clerk in Holy Orders, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improved methods of carrying cycle inflators and of
preventing their rattling.
With these objects in view I attach to a member of the cycle frame by any
suitable means a pair of sockets, or their equivalents, adapted to fit the extre-
mities of the inflator. These sockets are fixed and I give the inflator a power of
being elongated so as to insert its extremities into these sockets and so to sup-
port itself between them.
If not already done, I screw thread internally or externally one end of the
inflator and fit it with a corresponding screw threaded piece, the out extremity
of which is adapted to engage with one of the aforesaid sockets, but in such a
manner as not to revolve therein. If desirable the aforesaid piece may be
attached or attachable to one end of the flexible connecting tube and may form
one of the latter's fittings. Now if the sockets are fixed on a tube of the frame
at a proper distance apart and the screw-threaded piece aforesaid is made to
engage with its appropriate socket and the part of the inflator carrying the
piece be revolved in the proper direction, it is obvious that the other extremity
of the inflator will be forced into the other socket and the inflator held tightly
between the two. A reverse motion disengages it.
To further obviate rattling I provide the plug which is screwed into the barrel
and through which the piston rod passes with a conical projection on its outer
face and I shape the part it presses against when the inflator is closed with a
corresponding depression. When these engage by the end pressure before de-
scribed lateral shaking & rattling are prevented.
One of the sockets may be provided with, or give place to, a pair of jaws
adapted to close on and & hold the screw threaded piece.

page_text: formed to be particularly described and ascertained in and by the following
statement:
-
This invention relates to an improved method of attaching inflators of pneu-
matic tyres to the frames of cycles for the purpose of carrying them when not
in use, and it consists of a pair of sockets adapted to be fixed to the frame of a
cycle and engage the ends of the inflator when it is elongated by means of a stud
or its equivalent threaded into one of its ends.
In the accompanying drawing which illustrates-by way of example-some
methods of carrying my invention into practice:-
Figure 1 is a broken view in side elevation-partly in section-and Figure 2
is a view in transverse section on line x, x, Figure 1 showing one arrangement.
Figure 3 is a view in side elevation of the inflator, and
Figure 4 is a view in side elevation of the flexible connecting tube employed
in the arrangement illustrated by Figures 1 and 2.
Figure 5 is a broken view in side elevation-partly in section.
Figure 6 is a view in transverse section on line y, y, Figure 5 showing the
other arrangement, and
Figure 7 is a broken view in side elevation-partly in section--showing
another arrangement.
Throughout the views similar parts are marked with like letters of reference.
On to any convenient member X of the frame of the cycle are fixed-at a suit-
able distance apart according to the length of the inflator when closed up-two
clip brackets A, A, carrying sockets or their equivalents adapted to fit the ends
of the inflator. These brackets are preferably made out of sheet metal and are
adapted to be fixed to the frame of the cycle by one transverse screw and nut
located between the part adapted to encircle the member of the frame of the
cycle and the part adapted to form the socket or its equivalent, but other forms
of construction may be employed.
The inflator is of the usual construction consisting of a barrel B, a piston C,
a hollow piston rod D, a telescopic handle E formed on or attached to the
piston D and adapted to slide over one end of the barrel B, and a flexible con-
necting tube provided at one end with a nipple G adapted to be screwed into
a threaded hole in the front end of the cylinder B, and at the other end with a
socket Hadapted to engage the nipple of the inflating valve. In some inflators
provision is made for stowing the flexible tube F in the hollow piston when not
in use, in which case the socket H has an external screw threaded part h adapted
to screw into the end of the hollow piston so as to retain it therein, the socket
being provided with a milled flange h¹ to enable it to be rotated.
To provide for the elongation of the inflator I may utilise either the nipple G
of the flexible tube F as shown by Figures 5 and 6, the socket H of the said
tube as shown by Figures 1 and 2, or a special screwed piece J as shown by
Figure 7, the said pieces being adapted to engage the sockets or their equiva-
lents carried by the brackets A, A, in such a manner that they cannot revolve
therein thus preventing their rotation which enables the length of the pump
to be increased or diminished by rotating the part of the inflator into which the
said piece is screwed in one direction or the other.
In the construction shown by Figures 1 and 2 the milled flange on the
socket H has a flat such as h³ cut or formed on it making it of a D-shape, and
the socket a carried by the clip bracket A is of a corresponding shape, but it
will be obvious that both the shape of the flange and of the socket or its equiva-
lent may be of any other shape which will prevent the one rotating with respect to
the other when they are engaged. The outer end of the socket a is either
wholly or partially closed for the end of the flange to bear against or the said
flange may be stepped as shown in Figure 7 to enable it to bear against the
face of the socket a.
In the construction shown by Figures 5 and 6 the nipple G is provided with

page_text: an enlargement g which is preferably of a square shape in transverse section,
and the socket a of the clip bracket A is correspondingly shaped to receive it,
the end movement of the nipple with respect to the socket being prevented by
means of a flange g¹. The socket a in this construction is of such a size as will
enable the flexible tube F and the socket H to pass through it, as in this
arrangement the flexible tubo is not removed from the inflator when it is
mounted on the machine.
In the construction shown by Figure 7 a piece J is threaded externally to
engage either the hole in the end of the barrel B3 adapted to receive the nipple G,
as shown, or the hole in the end of the piston rod D adapted to receive the
socket H, the said piece having a D or equivalent shaped end j to engage the
socket a of the bracket A.
The clip bracket adapted to receive the other end of the inflator may either
carry a socket or its equivalent to receive the projection on the end of the
barrel Bas shown by Figure 1, or it may carry a stud a¹ or its equivalent to
engage the hole in the end of the telescopic handle as shown by Figure 5, both
the socket a and the stud a¹ being preferably of a cone shape.
It will be seen that if the brackets carrying the sockets a or their equivalents
are fixed on the member of the frame at a proper distance apart, the screwed
piece G, H or J as the case may be is caused to engage with its appropriate
socket and the part of the inflator into which the said piece is threaded is re-
volved in the proper direction, the other end of the inflator will be forced into
engagement with the socket or its equivalent carried by the other bracket
whereby the inflator will become tightly held and can be readily disengaged by
giving it a reverse motion.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
(1) Mounting inflators for pneumatic tyres on the frames of cycles by causing
one end of the inflator and a stud or its equivalent screwed into the other end
thereof to engage by elongation with brackets fixed to the frame of the cycle,
as set forth.
(2) Mounting inflators for pneumatic tyres on the frames of cycles by causing
one end of the inflator and a stud or its equivalent screwed in the other end
thereof to engage by elongation with brackets fixed to the frame of the cycle,
the arrangement being such that the engagement of the screwed stud or its
equivalent with its bracket prevents its rotation, as and for the purpose set
forth.
(3) Mounting inflators for pneumatic tyres on the frames of cycles by causing
one end of the inflator and the nipple or socket of the flexible connecting tube
screwed into the other end of the inflator to engage sockets carried by brackets
fixed to the frame of the cycle, as set forth.
(4) The combination with an inflator for pneumatic tyres, of a flexible con-
necting tube having the nipple by which it is attached to the barrel of the pump
D-shaped or polysided, and of a pair of sockets adapted to be attached to the
frame of a cycle at such a distance apart that the one end of the inflator and the
shaped nipple screwed into the other end thereof will engage the said sockets,
when the one is rotated with respect to the other.
(5) The combination with an inflator for pneumatic tyres, of a flexible con-
necting tube having the nipple by which it is attached to the barrel of the pump
D-shaped or polysided, and of a pair of sockets adapted to be attached to the
frame of a cycle at such a distance apart that the one end of the inflator and the
shaped nipple screwed into the other end thereof will engage the said sockets,
the arrangement being such that the engagement of the screwed nipple or its
equivalent with its socket prevents its rotation, as and for the purpose set forth.

page_text: (6) The combination with an inflator for pneumatic tyres, of a flexible con-
necting tube having the socket by which it is attached to the valve of the tyre
adapted to screw into the hollow piston for the purpose of stowing it away
when not in use, and of a pair of brackets to receive the end of the inflator and
the end of the screwed socket respectively, the said brackets being attached to
the frame of the cycle at such a distance apart that the inflator can be inserted
between the brackets when the socket is screwed home and can be firmly engaged
therewith by elongating the inflator by unscrewing the socket out of it, as
set forth.
(7) The combination with an inflator for pneumatic tyres, of a flexible con-
necting tube having the socket by which it is attached to the valve of the tyre
adapted to screw into the hollow piston for the purpose of stowing it away when
not in use, and of a pair of brackets to receive the end of the inflator and the
end of the screwed socket respectively, the said brackets being attached to the
frame of a cycle at such a distance apart that the inflator can be inserted between
the brackets when the socket is screwed home, and can be firmly engaged there-
with by elongating the inflator by unscrewing the socket out of it, the arrange-
ment being such that the engagement of the socket or its equivalent with its
bracket prevents its rotation, as and for the purpose set forth.
(8) The combination of parts herein before described and illustrated by the
acompanying drawing forming an improved method of attaching inflators for
pneumatic tyres to the frames of cycles.
