PROVISIONAL SPECIFICATION.
Improvements in and connected with Valves.
I GEORGE EDWARD GILPIN of 19 Westfield Terrace Bradford Yorkshire,
Mechanician do hereby declare the nature of this invention to be as follows:-
This invention consists in the improvements in valves hereinafter set forth
suitable for use to inflate cycle tires, cycle handles, air-beds or balloons and also
suitable for expanding any other inflatable article and also suitable for use in
connection with liquids or in connection with steam or vapour from liquids.
I provide a valve-socket the shank end of which is stepped or serrated, the body
of such valve-socket is of greater dimensions than the shank, such dimensions being
suitable to receive the valve.
The body of the valve-socket is provided with an internal female thread and the
shank is provided with a continuous passage extending from the end of such shank
to the hollow body part.
I next provide a suitable joint-washer and place such joint-washer to rest on the
bottom of socket-body the central hole of such washer being placed over the central
passage formed in shank.
I next provide a barrel-valve and form thereon a male thread and also form
therein a central hollow passage which may be rectangular or of other suitable
transverse section, this central passage does not pass through the end but a solid
end is left, the external face of solid end being provided to stop the internal main
passage of shank as hereinafter more fully described. One, two, three, four, or any
desired number of passages are formed in the lower part of barrel-valve such
passages reaching or passing from the external periphery of barrel into the square
or other shaped central passage so that air or liquid passing into the square or
other shaped central passage would pass out through the series of outlet passages,
the barrel-valve would then be screwed into the valve-socket until the solid end-
face of such valve pressed against the washer placed over the shank passage of
valve socket.
1 next provide a pump-connection which consists of a barrel from which projects
transversely a connection block, a passage is provided through one of the faces of
connection block, leading into the barrel passage.
I next provide a key-spindle, one end of which consists of a cylindrical or solid
pin or bar surmounted by a suitable thumb-bit or rose-wheel the other end of key-
spindle being formed square, or of the required shape to fit the square or other
shaped hole formed in the centre of barrel-valve. The key spindle is passed into
the pump casing, the completed pump connection is then screwed into or on to
the valve-socket, the square end of spindle passing into the square passage of
barrel-valve.
I next utilize any suitable pump which may be provided with a flexible tube the
end of such flexible tube being connected to a metal outlet-piece this metal outlet
piece being secured to the block of pump-connection by any suitable mechanical
means.
My improvements in and connected with valves would then be in position ready
for use, the shank end of the valve-socket would be permanently secured to a cycle
tire or other article to be inflated, the pump would be operated in the following
manner so as to pump air through the connecting block.
In order to pump air
into cycle tire the key-spindle would be rotated upwards and by such rotation the
barrel-valve would be unlocked, that is to say rotated upwards from the bottom of
valve-socket thus exposing the main passage formed in the valve-socket.
It will
be apparent that so long as the square end of the key-spindle remains in the central

page_text: passage formed in the barrel-valve (providing such square shank is a good fit in the
square passage of valve) air could not enter the valve, therefore the valve-spindle
is drawn upwards until the square part leaves its bearing in barrel-valve: a free
passage is thus provided through which air can pass from the pump through the
connecting block of my invention, down the square central passage formed in
barrel-valve and out through the peripheral passages, from whence it would pass
through the main passage in shank into the tire, thus expanding the tire to the
required tension, the key-spindle would then be pushed down the barrel of pump
connection, the square part of spindle passing again into the square passage of
barrel-valve so that by rotating the spindle the barrel-valve would be screwed
down again until the end of valve again took a bearing on the washer and closed
the shank passage. The pump connection would then be unscrewed and removed.
A suitable cap having been previously provided and hung by means of a chain on
to any suitable part of the bicycle or other article, such cap would be screwed into
the valve-socket "not for the purpose of keeping the valve air tight" but to
prevent the internal peripheral threads of valve-socket being damaged, such
threads must be kept in good condition to receive the pump connection.
By varying the configuration of the shank-end of valve socket, such shank end
can be inserted in expandable cycle handles, air beds, cushions, or any other article
suitable for use in conjunction with my improved valve. A separate valve-socket
(with valve) would be permanently secured in each tire or other expandable part
or article, a cap being also hung permanently, near each of such fixed valve-
sockets.
I wish it to be distinctly understood that I do not claim the pump as any part of
my invention. I merely utilize any ordinary air pump as a motor or supply for my
improved valve and connections.
A pump connection would be secured permanently to the outlet tube of air pump,
consequently each cyclist or other person utilizing a valve-socket would require an
air pump on to which would be secured my improved pump connection.
When using my improved valve and connections for steam, vapour, or liquid the
steam vapour or liquid conduit would be secured to the pump-connection by any
suitable mechanical means; the steam, vapour or liquid passing through the valve
and connections in the manner hereinbefore described in reference to air.
When using my barrel-socket in an expandable cycle-handle I do not suspend
the cap by means of a chain but make the outer end-face of such cap of a suitable
configuration to correspond with the contour of handle, so that it will not catch in
the clothing of rider.

COMPLETE SPECIFICATION.
Improvements in and connected with Valves.
I GEORGE EDWARD GILPIN of 19 Westfield Terrace, Bradford Yorkshire,
Mechanician, 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 consists in the improvements in valves hereinafter set forth suitable
for use to inflate cycle tires, cycle handles, air-beds or balloons and also suitable for
expanding any other inflatable article and also suitable for use in connection with
liquids or in connection with steam or vapour from liquids.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is constructed and used, similar letters refer to similar
parts throughout the several views.

page_text: In carrying out my invention I provide a valve socket a and form therewith a
stepped or serrated shank b, the socket would be provided with the screw thread c
and the shank is pierced with the continuous passage d.
I next provide the joint washer e and place it to rest on the bottom of socket
body.
I next provide the barrel-valve as shewn at Figure 2 and form thereon the male
thread and form therein the central passage g, one, two, three, four, or any desired
number of passages are formed in the lower part of barrel-valve I have shewn two
of such passages at hand; the barrel-valve as shewn at Figure 2 would next be
screwed into the valve socket a Figure 5. until the solid end face m pressed against
the washer e.
I next provide a pump-connection as shewn at Figure 3, which consists of the
screwed barrel-part n from which projects the connecting-block o, a passage bb is
provided through one of the faces of connecting block preferably at p leading into
the barrel passage q: a key spindler is next provided which may be cylindrical
when combined with large connection-blocks such as would be used for steam, but
which would by preference be solid when used with small connecting blocks
suitable for use to expand cycle-tires: the key spindle would be surmounted by a
suitable thumb-bit or rose-wheel s, the bottom end t of key-spindler being formed
square or of the required shape to fit the square or other shaped hole g formed in
the centre of barrel-valve. The key-spindler is then passed into the pump-casing,
the completed pump-connection is then ready to be screwed into or onto the
valve socket; the male barrel thread taking into the female thread c of valve
socket.
My improvements in and connected with valves, would then be ready for use, the
shank end of valve-socket would be permanently secured to a cycle-tire or other
article to be inflated, the steps or serrations a a form shoulders or collars by means
of which the shank can be tied or secured to a cycle-tire, air-bed, cushion, balloon
or other article to be inflated.
Each person who uses my valve-socket and valve will also require the pump-
connection, that is to say a cycle manufacturer could fix one hundred valve sockets
in one hundred pneumatic tires and also two hundred valve-sockets in two hundred
expandable handles, the three hundred articles could then be expanded by the use
of one pump connection and one air pump in the manner hereinafter set forth.
The pump-connection is screwed into one of the valve sockets a, the male barrel
thread taking into the thread c.
I next utilize any suitable pump which may be provided with a flexible tube or
other suitable air conduit, the end of such tube or conduit. being connected to a
metal outlet piece, this outlet piece may be in the form of a nozzle to screw into
inlet passage b b, such nozzle being a ready means of connection when the is
pump

page_text: used to expand cycle tires, air-beds and other small articles, but in expanding
balloons or other large containers the connection would by preference consist of a
gland-screw or other equivalent mechanical joint.
go
The conduit nozzle would be screwed into the inlet passage bb. In order to
pump air through the pump-connection into the pneumatic tire, the key-spindle
would be rotated upwards and by such rotation the barrel-valve would be unlocked,
that is to say; unscrewed and rotated upwards from the bottom of valve socket,
thus uncovering the main passage d formed in the valve-socket; it will be apparent
that so long as the square end of key-spindle remains in the central passage g
formed in the barrel valve, air could not enter the valve-passage g therefore the
valve spindle is drawn upwards until the square end leaves its bearing in the barrel-
valve; a free passage is thus provided through which air can pass from the pump,
through the connecting block, into the barrel passage q, down the square central
passage formed in barrel-valve and out through the peripheral valve passages h
and k from whence it would pass through the shank passage d into the tire, thus
expanding the tire to the required tension; the key spindle would then be pushed
down the barrel passage of pump connection until the square end of spindle
again passed into the square passage g of barrel-valve so that by rotating the
spindler, the barrel valve would be screwed down again until the end m of valve
again took a bearing on the washer e and closed the shank passage
the pump
connection would then be unscrewed and removed; a suitable cap c c having been
previously provided and hung by means of the chain link d d to any suitable part
of the cycle rim (or other article); the male screw plug e e of such plug would be
screwed into the valve socket over the screwed down valve, the end ff of such plug
not reaching to the top face g g of barrel-valve, this plug is provided to keep the
threads c of valve socket in good condition ready to receive the male threads of
pump connection; by proceeding in a precisely similar manner to that hereinbefore
described in inflating one tire, the remaining 99 tires can be inflated by the use
of one pump-connection and one pump.

By varying the configuration of the shank-end of valve-socket such shank ends
can be inserted in expandable cycle-handles, air-beds, cushions or any other article
that requires inflating; a separate valve socket (with valve) being permanently
secured in each tire or other expandable part or handle, a cap being hung per-
manently near each of such fixed valve sockets; the valve socket shewn in section
at Figure 8 is suitable for use with inflatable cycle-handles, the flange / being
provided to imbed in such handle, the shank being dispensed with and the air
passage formed at jj; the plug as shewn at Figure 6 is formed with a square or
other shaped passage to match the passage g so that after the handle has been
inflated and the barrel-valve screwed down, the cap k k can be screwed in its
position shewn at Figure 8, to match the contour of handle end, the square end t of
spindle being introduced into the passage m m when screwing the cap in position.
From the foregoing description it will be readily understood that a cyclist or
other person can utilize my valve socket and barrel valve to the tire, to the
handles, to the saddle, and to any other inflatable part of a cycle or to any other
inflatable article and that he will only require one air pump and one pump-
connection to inflate the whole of the articles.
To save loss of parts I in some cases prefer to secure the pump-connection per-
manently to the nozzle of pump air tube, in other cases the pump-connection will
be a separate article to be first screwed into valve socket and afterwards attached
to air-pump.
When using my improved barrel-valve and connections to convey steam, vapour,
or liquid, a steam, vapour, or liquid pump would be used in lieu of an air pump, the
conduit of such steam, vapour, or liquid pump would in such cases be made out of
metal or other suitable material and would be attached to the pump connection by
means of the screwing nozzle joint herein before referred to in relation to air pumps
or any other equivalent mechanical joint connection can be utilized.

page_text: 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,
1st. The improvements in and connected with valves, as illustrated and described,
for the purpose of inflating cycle tires, cycle handles, air-beds, balloons and other
inflatable articles.
2nd. The improvements in and connected with valves as illustrated and described,
for use in connection with liquids or in connection with steam or vapour from
liquids.
