I, ALBERT FREDERICK COLE, of Sutton Park Road, Kidderminster, in the County
of Worcester, Manufacturer, do hereby declare the nature of this invention to be
as follows:
This invention relates to improvements in valves for use with pneumatic tyres
for cycles, auto cars, carriages, and for other purposes and has for its object,
simplicity, ease of manipulation and efficiency for the purposes intended, and 1
will now describe the manner of carrying out my invention.
In my first form I construct an externally screwed stem or body piece (herein-
after called the "body piece") provided with a flange or disc at base, the upper
side of said flange being grooved with one or more grooves. A base plate and
nut for clamping valve to air chamber; and for ensuring a tight and improved
joint 1 sometimes place a rubber, leather or flexible ring between the air chamber
and base plate, which when clamped together by nut compresses air chamber and
flexible ring within the grooved out portion of flange of body piece; I may also
use a canvas, rubber, or leather pad cemented over or under flexible ring and
extended a short distance on to air chamber. A rim nut (hereinafter called the
rim nut") for binding valve to rim of wheel, is recessed or grooved out circum-
ferentially at any portion thereof, but preferably at the upper side for the purpose
of containing or carrying a wire or other ring which when placed within the
groove may be so bent or manipulated as to close and revolve within the grooved
space, and to form an eyelet or opening in the ring projecting beyond the groove
and intended to carry one end of a chain or equivalent; for which purpose the said
eyelet may extend outwards, or be turned upwards, twisted, or bent to any other
suitable form. The upper end of body piece is preferably of less diameter than
the lower portion and is screwed externally, and centrally perforated or bored
therethrough within or on top of body piece is made a recess for carrying a
leather washer or other packing and forms a valve seat for the stop valve herein-
after to be described.
;
A cylindrical chamber (hereinafter called the "valve chamber") open and of
greater diameter at the lower portion, is internally screwed for a portion of its
length to correspond with the screwed portion of body piece; the upper portion of
valve chamber is of less diameter than the lower portion and the roof or top thereof
is made conical (or an equivalent shape to form a valve seat for the check valve
hereinafter to be described) and an extension above is bored out with a smaller
passage. The exterior of said extension of valve chamber is screwed (and herein-
after called the "nozzle") and forms the pump nozzle connection or part to
which the inflator is attached when inflation is required. Into the valve chamber
I insert a check valve (hereinafter called the "check valve") preferably conical to
correspond with conical portion in top of valve chamber and formed with an
upwardly extending stem preferably flattened, grooved, or made hollow, and

page_text: which passes and slides freely through the upper passage of extension or nozzle. I
next insert a stop valve (hereinafter called the "stop valve") preferably hollow or
recessed at base and shouldered outwardly at the upper end, the shoulder being of
such external diameter that the stop valve may slide within the portion below the
shoulder formed by the difference in diameter of valve chamber. Around the
circumference of stop valve below shoulder thereon I place a coiled spring for
pressing the stop valve up to the shoulder of valve chamber.
A roughened or winged nut, cap or cover (hereinafter called the "cap") prefer-
ably at the lower portion of somewhat larger internal diameter than the external
diameter of valve chamber below nozzle, and the portion above of less diameter
and internally screwed to correspond with the external thread on nozzle; a smaller
external bore or passage is preferably made through (or partly through) top end of
cap, and a pin (shouldered when carried entirely through cap) inserted therein;
the said pin when carried through may extend slightly above top of cap; the said
pin also extends downwards within cap sufficient distance to operate check valve
and stop valve. A portion of outside of cap is grooved for retaining a ring or wire
to the eyelet of which is attached the other end of chain before described as attached
to rim nut; or instead, the pin may revolve in cap and be bored therethrough to
contain a link for connecting the chain thereto.
The action of valve when attached to a pneumatic wheel or other air chamber
I will now describe:-After check valve, stop valve and spring are inserted in
valve chamber; and stop valve seat washer inserted in recess of body piece; these
two portions are screwed together and the joint made pressure tight with a washer;
the pump is connected to nozzle and air chamber inflated. The air pumped or
forced through valve passes the conical check valve (whose movement is limited by
the space between conical seating and top of stop valve) and around shouldered
part of stop valve, which is notched, grooved, or fits sufficiently loose against
shoulder of valve chamber to permit of the air passing around or through to
smaller central perforation in body piece to air chamber. Upon removal of pump
the cap is screwed on to nozzle and the central pin of cap presses down end of
stem and lowers check valve, the check valve in its turn presses down the stop
valve against the force of spring on to the stop valve seating in body piece,
ensuring a permanently tight joint. When the cap is removed the spring presses
up stop valve on to shoulder and the check valve then comes in action on its seat
above to prevent back pressure and the stem thereon allows of deflation when
desired.
An upwardly extending stem or projection may be formed on the stop vaive;
and the underside of check valve recessed for the extending stem to project therein;
also the spring may be kept in position by inserting in valve chamber a ring, or
screwing a gland or its equivalent therein."
In a modification of valve I construct the shouldered stop valve with an upwardly
extending hollow stem, the said hollow, or bore, may be carried through, or towards
the lower end of stop valve, and within or on such bore is made a conical or other
seating for the check valve; the check valve with stem for deflating is inserted
therein; the bore closed at base, and side passages below the check valve formed
for the air to pass from check valve to the underside of stop valve when operated.
In the valve chamber and surrounding the upwardly projecting hollow stem above
shouldered portion of stop valve, I insert a leather washer or other packing to
prevent escape of air therethrough during operations, the spring being sufficiently
strong to lift the stop valve upwards and overcome the resistance of the leather
washer or packing. I may sometimes carry the check valve entirely through the
base of stop valve, then made conical or other suitable shape to form check valve
seat; the under side of check valve itself (recessed after the manner of stop valve
described) or in some cases both the underside of check valve and stop valve may
press on the stop valve seat to close when operated by the cap; I then preferably
perforate the hollow stem above the packing and insert a pin through check valve
stem and perforation to limit the movement of check valve, or I may shoulder these

page_text: portions or use equivalent devices to prevent check valve falling on to stop valve
seat, when the stop valve portion is lifted by the spring on removal of the cap.
Other modifications may be made such as:-The downwardly projecting central
pin in cap may be dispensed with, and the upwardly projecting stem. of check
valve or stop valve correspondingly lengthened, the top of cap then operating the
check and stop valves. The cap may be sometimes screwed on to valve chamber
or on to body piece, instead of being screwed on to nozzle.
The spring described may be placed above stop valve shoulder, on hollow stem,
within recess of stop valve, or stop valve seat, or in any other suitable position to
operate stop valve, and may be coiled, conical, or of other form.
In any of the valves or modifications herein described the leather washer or disc
or other packing may be inserted in the recess in the valve instead of in the
recess in valve seat, the valve seat then being raised to suit. The check valve and
seating may be spherical, or constructed after the manner of the stop valve and
seating described, and both the check and stop valves and seatings may be varied
to any suitable shape or form. The stop valve may be extended downwards,
shouldered, reduced in diameter and made tubular, such portion being carried
through a leather washer or other packing instead of bedding on a valve seat; the
air may pass through one or more passages when the stop valve is raised, and the
said passages slide within the packing and the shoulder presses thereon when
closed. In cases where the leather washer, or disc. or other packing is recessed
into stop valve and the check valve is contained within; the passage when formed
therethrough to base (for insertion of check valve) may be closed by a metal
disc being inserted in the recess before the leather washer, or disc or packing is
placed in position.
The valve chamber may be formed within the body piece and the upper or open
end thereof closed by a downwardly extending screwed portion on nozzle. The
screwed threadings described as internal, may be made external, and the external
threadings made internal..
The position and number of washers of leather, rubber, or other packing may be
varied and kept in position or tightened by means of metal washers, rings,
glands or portions screwing the leather washers or other packing together. The
valve chamber may be made in sections, and the parts screwed or otherwise
fastened together in order to manipulate and contain separate, or partly separate
either the valves, springs, washers or packing in their respective positions.
A socket may be carried over or on valve chamber and body piece, to prevent
valve chamber turning round and to ensure the tightness of joints.
Instead of the ring revolving in rim nut, a pressing or stamping of similar shape
may be connected to rim nut; or a piece of wire so bent as to encircle rim. nut and
to form an eyelet for the. chain; or a small eyelet may be screwed or otherwise
fastened into the rim nut; or a hole may be bored through the rim nut and a
headed or other wire bent therein, or a link inserted. I may sometimes carry a
tube above the rim nut to cover or partly cover the valve chamber, the lower end
of tubing may be or may not be fastened to rim nut, or may be shouldered to
rim nut so as to be capable of being turned round or revolved; or the rim nut may
extend upwards in the shape of a tube and screwed internally the whole length or
a portion thereof. The upper end of tube may be grooved, perforated or bent
in a suitable form for carrying the one end of chain, the other end being attached
to cap.

Improvements in Valves.
I, ALBERT FREDERICK COLE, of Sutton Park Road, Kidderminster, in the County
of Worcester, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in valves for use with pneumatic tyres,
for cycles, auto-cars, carriages, and other purposes, and has for its object simplicity,
ease of manipulation, and efficiency for the purposes intended.
I will now describe my invention by referring to the accompanying drawings,
the same letters of reference indicate like parts, or equivalent portions, in all the
figures.
Figure 1 represents a sectional elevation of my valve, and consists of an
externally screwed body piece B (and hereinafter called the body piece) the base
thereof being constructed in the usual manner, for attachment to the article to
be inflated. The upper end of body piece B, is preferably of less diameter than
the lower portion, and is screwed externally, and centrally bored therethrough B².
The top of body piece B is made in the form of an annular recess 135, to contain the
leather washer W₁ or other packing, for the purpose of forming a valve seat, for
the stop valve K, hereinafter to be described.
A cylindrical chamber A, (hereinafter called the "valve chamber,") open at the
lower portion, is internally screwed for a portion of its length, to correspond
with the screwed top portion of body piece B. The upper portion of valve
chamber A at A4, is of less diameter than the lower portion; and the roof or
top A¹ thereof is made conical, (or an equivalent shape, to form a valve seat for the
check valve V hereinafter to be described). An extension above A' is bored out,
forming a smaller passage A². The exterior of said extension of valve chamber is
screwed at A3, (and hereinafter called the "nozzle,") to form the pump nozzle
connection, or part to which the inflator is attached when inflation is desired. Into
the valve chamber A I insert a check valve V carrying an upwardly extending
stem V, (and hereinafter called the "check valve,") preferably conical at V3 to
correspond with conical portion A¹ in top of valve chamber A. The said check
valve stem V1, freely slides through the upper passage A2, within nozzle A³. I
next insert a stop valve K. (hereinafter called the "stop valve,") hollow or recessed
at base K¹, and shouldered outwardly at the upper end K2: the shoulder K2 being
of such external diameter, that the stop valve K may slide within the portion below
the shoulder A4, of valve chamber A. A slot, or saw cut, or groove K° is made
across the top face of stop valve K. Around the circumference of stop valve K,
below shoulder K2, is placed a coiled spring S, preferably made conical, or the lower
coils opened out to bear on the sides of valve chamber A, to maintain stop valve,
and check valve, in position in valve chamber A, when unscrewed from body
piece B. The said spring S presses the stop valve K up to the shoulder A* of valve
chamber A.
A roughened or winged nut or cap C, (hereinafter called the "cap,") is prefer-
ably at the lower portion C¹ of somewhat larger internal diameter than the external
diameter of valve chamber A¹, below nozzle A³ the portion above is internally
screwed at C², to correspond with the external thread on nozzle A³. A smaller
central bore C3, is made through, (or partly through) the top end of cap C, and a
pin P inserted therein the said pin P also extends downwards at P1, within cap C
sufficient distance to operate check valve V, and stop valve K. A portion of
outside of cap C is grooved for carrying a ring or wire D, to which is attached
one end of a chain or equivalent J. The other end of chain J is attached to a
link or eyelet T fastened in, or inserted through a perforation at the upper end N¹
of rim nut N.
The valve chamber A screwed to body piece B, is made pressure tight in the

page_text: joint by means of a flexible washer W₁, preferably surrounded by a roughened
metal ring W, to maintain the flexible washer W₁ in position, and to avoid it
unduly opening out, or flattening, when A and B are screwed together.
The action of valve shown open in Figure 1, when attached to an air chamber 19
as follows:-The cap C is removed, the pump connected to nozzle A³, and the air
chamber inflated. During inflation the air is forced down passage A², past the
conical valve V, (whose movement is limited by the space between conical seai-
ing A and top of stop valve K,) through slot K°, and around shouldered part K³
of stop valve K, through central perforation B2, and B in body piece B, to air
chamber. Upon removal of the pump, the cap C is screw d on to nozzle A³, as shown
in Figure 2, and the central pin P¹ within cap C, presses down top end of stem V₁,
and lowers check valve V; the check valve V, then presses down the stop valve K,
against the force of spring S, on to the washer W of stop valve seating 15 in body
piece B, ensuring a permanently tight joint. When the cap C is removed, the
spring S presses up stop valve K on to the shoulder A4; the air pressure within
air chamber, forces check valve V upwards on to its seating A¹, to prevent back
pressure; and the stem V1 thereon, allows of deflation when desired.
In the modification shown closed in Figure 2, the stop valve K carries a leather
blank W, inserted within recess K¹, and is extended within body piece B; the
raised portion B, (made by the recess B5) forms the seating for the stop valve K.
The pin P is bored above top of cap C, and carries a ring or link D1, to which is
attached the chain or equivalent J; the pin P may be inserted tightly within
cap C, or loosely so as to revolve. A gland or ring L, preferably split, is inserted
within valve chamber A, below spring S, to maintain the spring, stop valve, and
check valve in position.
In the modification shown in Figure 3, the valve chamber A screws into the
body piece B, the base of valve chamber A, is preferably turned inwards at A5, and
a saw cut or notches A made across, to permit of the free passage of the air. The
stop valve K of less diameter at K3, is carried up into valve chamber A, and headed
at top K. The spring S preferably opened out at base to maintain it in position,
is inserted within body piece B, and surrounds stop valve K up to shoulder K².
The portion B1, B2, B and B is shown screwed or otherwise fastened within body
piece B. The head K4, of stop valve K, is forced past the turned inward portion A5,
which is to prevent the stop valve, and check valve falling out of valve chamber A,
when the valve is taken apart; the reduced portion K3 below head K+, allows
the stop valve K to operate freely, and permit of the free passage of the air.
In the modification shown in Figure 4, the valve chamber A screws within
body piece B, the stop valve K carries an upwardly extending stem K³, surrounded
by spring S. The stop valve K, and spring S, are maintained in position by means
of a pin or equivalent O, at top of K³, and a gland G screwed into base of valve
chamber A, below spring S: a sawcut or notches G¹ are made at base of gland G
to permit of the free passage of the air.
:
In the modification shown closed in Figure 5, the stop valve K carries an up-
wardly extending stem K3 and is bored throughout; within such bore is made a
conical seating K, for the check valve V: side passages K, are formed below seat-
ing K5 and the base of stop valve K at K', is closed by means of a metal disc M,
and flexible or leather blank W. The check valve V inserted within K, carries an
upwardly extending stem Vi for deflating purposes. Within top of valve
chamber A, and surrounding upwardly extending hollow stem K³, is secured a
leather washer W3 or other packing. The spring S below shoulder K2, is made
sufficiently strong to operate stop valve K, and to overcome the resistance of the
leather washer or other packing W³.
In the modification shown in Figure 6, the check valve V, is carried entirely
through the stop valve K, a conical face K7 at base of stop valve K, forms the
seating for the face V3, of check valve V. The underside of check valve V,
(recessed at V after the manner of the stop valve K at K¹ before described) pressea
on to the washer W, of stop valve seating B5 on body piece B, to close, when the

page_text: cap C is screwed down on nozzle A³. A pin 0, is inserted through check valve
stem V, and stop valve stem K³, (or equivalent means,) to limit movement of check
valve V.
The stop valve stem K³ in Figures 5 and 6, is pressed down by the cap C, to
close stop valve K; during inflation the air passes down central bore of stop
valve K, past check valve facing, through passages to air chamber.
Figure 7 shows the check valve V recessed at V after the manner of the stop
valve K, at K, thereby forming an annular facing V, instead of the conical
facing V³ hereinbefore described.
An upwardly extending stem or projection, may be formed on the stop valve K,
and the underside of check valve. V recessed, for the extending stem of siop
valve K to project, and freely slide therein.
In any of the valves or modifications herein described, and illustrated, the
leather disc, washer or other packing W, may be inserted in the recess in valve,
or in the recess 15 of valve seating. The position and number of washers of
leather, rubber, or other packing may be varied, and kept in position by means
of metal washers or rings, glands or portions screwing the leather or packing and
valve together.
I may sometimes carry on body piece B, a tube or socket above the rim nut N,
to cover or partly cover the valve chamber A, to prevent the valve chamber A
and nozzle turning round, when pump is attached to, or detached from nozzle A³.
The upper end of said tube or socket may be grooved, perforated or bent in a
suitable form, for carrying the ring or eyelet and end of chain J, instead of attach-
ing the chain to rim nut N hereinbefore described.
Figure 8 in section, and Figure 9 in plan, shows the rim nut N bent or pressed
outwards at N, and perforated to carry a link T, for chain or equivalent J.
In Figure 10, the top of rim nut is shown with a bent over portion N2, perforated
to carry the link T, for the chain or equivalent J.
Figure 11 shows the tube or socket X, (above the rim nut N,) grooved at X1, to
contain the ring R, and the upwardly or outwardly turned evelet R¹, (and which
may be also twisted or bent, in order to prevent the ring R, within groove X¹
opening out,) to which is attached one end of chain or equivalent J, the other
end being attached to ring D', or wire D of dust cap C.
Figure 12, shows the tube, or socket X, carrying a link or wire T screwed,
headed, or otherwise fastened to tube or socket X, for carrying chain or equi
valent J.
r
By attaching one end of chain or equivalent J, to the upper end of rim nut N,
or socket X, in the manner described. and illustrated in Figures 1, 8, 9, 10, 11
and 12, and the other end to dust cap C, permits of the use of rim brakes, on rims
of wheels without interfering, or dispensing with the chain J; and is a convenient,
and efficient manner of carrying the parts together, to reduce the risk of loss
of parts to a minimum, when such portions are detached from valves. The valve
also possesses the further advantage, of being taken through, or from rim of
wheel, without taking valve portion to pieces.
In the event of the cap C being lost or misplaced, the washer W; (preferably
surrounded by metal ring W*) between valve chamber A. and body piece B, may
be removed, and the valve chamber A screwed on to body piece B, thus dispensing
with the washer W or W. Under these circumstances the pump is attached to
nozzle, the valve chamber A slightly unscrewed, and air chamber inflated. On
removal of the pump, the valve chamber A is firmly screwed down, which presses
the stop valve K by means of the shoulder K2, on to its seating on body B, thereby
forming a permanently tight joint.
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 a valve for pneumatic tyres and the like; the combination, which consists
