I, GERARD FEATHERSTONE GRIFFIN, of Hampton Court Villa, Acton Vale, W.,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in caps and couplings for pipes tubes
hose shafts rods and other articles, and for any analogous purposes and the object
is to provide an air and water tight joint or coupling which can be more easily
connected and disconnected than the usual screw one. Although more especially
intended for use with the inflating valves of the pneumatic tyres of cycles and
other vehicles I do not confine it to that one use as it can with or without modifi-
cation be used for other than that particular purpose.
The arrangement which constitutes my invention consists essentially of two
parts, namely a socket portion and a plug portion fitting therein. The socket
portion has two concentric walls upstanding at one end, the other end being
screwed or otherwise formed and provided for attachment to the article with which
the part is to be used. The space or channel between the walls is bridged by a pin
passing across it from wall to wall and if desired there may be more than one
such pin. The second or plug part has a rim at one end, the rim being of such
size as will fit snugly into the channel or space between the walls of the socket
portion. In this rim is an upwardly slanting notch or open ended slot or more
than one of such notches. In practice I prefer to have one pin and two notches.
When the plug is to serve as a cap, say for a cycle valve, the un-notched end is
closed and may be formed with a suitable terminal. When the plug is not to
serve as a cap the un-notched end is to be screwed or otherwise attached to the
article with which it is to be used. Milled edge projections or other devices
may be provided on each portion to facilitate the attachment and detachment of
them to and from each other. To make the joint air and water tight I provide
within the plug a disc-like or a ring-like rubber spring or other resilient washer
which when the two parts are coupled together will press on the edge of the inner
wall of the socket portion and so form a seal. In use the plug part is placed with
its rim in the space between the concentric walls so as to receive the pin or pins
within the upwardly slanting notch or notches in the said rim. The plug is then given
a partial rotation by which action the pin or pins rides or ride up the notch or
notches which causes the inner wall to be wedged up against the washer and so
make an air and water tight joint. The pin when it reaches the top of the
notch enters a small recess at that top end.
When the arrangement is applied as a substitute for the usual cap of a cycle
tyre inflating valve, the usual cap is screwed off and the socket and plug which
constitute my invention are put on instead. The plug in this case is of course
of cap shape and may be chained to the spokes as usual. The pump nozzle and
the flexible or other connections will be arranged to attach to each other and to
the valve by couplings of the kind already described.

page_text: It will be observed from the description that in all cases the rim of the plug
portion is shrouded within the space between the concentric walls of the socket
part. In some cases also the pin or pins need not extend entirely across the
channel between the walls. The plug and socket portions are to be made of metal
or other suitable material or combination of materials.

Improvements in Caps and Couplings for Piper, Tubes, Hose, Shafts,
Rods, and other Articles and for any analogous purposes.
I, GERARD FEATHERSTONE GRIFFIN, of Hampton Court Villa, Acton Vale, W.,
Gentleman, 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 improvements in caps and couplings for pipes tubes
hose shafts rods and other articles and for any analogous purposes and the object
is to provide an air and water tight joint or coupling which can be more easily
connected and disconnected than the usual screw one. Although more especially
intended for use with the inflating valves of the pneumatic tyres of cycles and
other vehicles I do not confine it to that one use as it can with or without modifi-
cation be used for other than that particular purpose.
The
The arrangement which constitutes my invention consists essentially of two
parts, namely a socket portion and a plug portion fitting therein and to more
fully explain the construction of each part I make reference to the accompanying
drawings in which Fig. 1 is a front view Fig. 2 a longitudinal
section and Fig. 3 a plan of the socket portion, and Fig. 4 a front
view, Fig. 5 a longitudinal section and Fig. 6 a plan of the plug
portion. Similar letters indicate the same parts wherever occurring.
socket portion has two concentric walls a and b upstanding at one end, the
other end being screwed as at c or otherwise formed and provided for attachment
to the article with which the part is to be used. The space or channel d between the
walls a and b is bridged by a pin c passing across it from wall to wall and if desired
there may be more than one such pin. The second or plug part has a rim f at
one end, the rim being of such size as will fit snugly into the channel or space d
between the walls a and b of the socket portion. In this rim f is an upwardly slant-
ing notch or open ended slot 9 or more than one of such notches each terminating
with a recess h. In practice I prefer to have one pin e and two notches g. When
the plug is to serve as a cap say for a cycle valve, the un-notched end is closed
as shown by dotted lines in Fig. 5 and may be formed with a suitable terminal.
When the plug is not to serve as a cap the un-notched end is to be screwed or
otherwise attached to the article with which it is to be used. Milled edge pro-
jections or other devices may be provided on each portion to facilitate the attach-
ment and detachment of them to and from each other. To make the joint air
and water tight I provide within the plug a disc-like or a ring-like rubber spring
or other resilient washer which when the two parts are coupled together will
press on the edge of the inner wall b of the socket portion and so form a seal.
In use the plug part is placed with its rim f in the space d so as to receive the pin
or pins e within the upwardly slanting notch or notches g in the said rim f. The
plug is then given a partial rotation by which action the pin or pins rides or ride

page_text: up the notch or notches 9 which causes the wall b to be wedged up against the
washer i and so make an air and water tight joint.
When the arrangement is applied as a substitute for the usual cap of a cycle
tyre inflating valve, the usual cap is screwed off and the socket and plug which
constitute my invention are put on instead. The plug in this case is of course
of cap shape and may be chained to the spoke as usual. The pump nozzle and
the flexible or other connections will be arranged to attach to each other and to
the valve by couplings of the kind already described.
It will be observed from the drawings and description that in all cases the
rim f of the plug portion is shrouded within the space d between the concentric
walls a and b. In some cases also the pin or pins e need not extend entirely across
the channel d. The plug and socket portions are to be made of metal or other
suitable material or combination of materials.
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. In disconnectible couplings a socket portion having two concentric walls
bridged by a pin or by pins extending across the space or channel between the said
walls and a plug portion having a rim provided with an upwardly slanting notch
or open ended slot or with several such notches or slots, the said rim fitting into the
space between the walls of the socket portion and its notch or notches being
intended to receive the pin or pins of the socket in such manner that by a
partial rotation of the plug portion the pin or pins is or are caused to ride up
the notch or notches and cause the inner of the concentric walls to be wedged up
against a resilient washer provided within the said rim, the whole substantially
hs described in the above specification and exemplified in the accompanying
drawings.
2. A modification of the arrangement claimed in the preceding claim by which
modification the plug has a cap like formation substantially as described in the
above specification and exemplified by the accompanying drawing.
