PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Supplying Gas or other Fluid
on Prepayment.
We JOHN HAWKYARD of Shaws Lane Upper Mill Saddleworth in the County
of York Foreman, and JOSEPH BRADDOCK of 72 Windsor Road Oldham in the
County of Lancaster, Gas Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements upon the gas supplying apparatus
invented by us and described in the Specifications of Letters Patent granted to
us Nos. 12584 and 14655 both of the year 1890, wherein the gas supply valve
is fixed at or near one end of a spindle which is capable of an end wise and also
of a revolving motion, and upon which spindle are two wheels to one of which
motion is given direct from the action of the gas meter and to the other, motion
is communicated by means of the coin in the reciprocating, oscillating, or revolving
coin receiver; the endwise motion for opening or closing the valve being given
to the spindle by an inclined plane or cam surface on one wheel acting on a
fixed projection on the other, or vice versa.
According to our present invention we place the valve outside the seating and
with its face towards the wheels above mentioned so that its closing movement can
be obtained by a pull instead of a push or thrust and another advantage is thereby
gained which is that the frame and valve seating can be cast all in one piece if
desired and ready access may be had to the valve for repairs or renewal without
disturbing the other parts of the apparatus.
.
We provide one of the said wheels with a sloping projection or finger and the
other with a corresponding sloping slot or notch so that when the one wheel
overtakes the other the side of the said sloping notch acting against the side of
the said sloping projection (or vice versa) will thrust the said wheels asunder or
draw them together and thus open or close the valve by giving the requisite
end wise motion to the valve spindle, the closing motion being given by a forward
pull, and the opening motion by a backward thrust as before described without
the necessity for any spring or other auxiliary.
By preference we make the stop valve of metal and in the face thereof we make
an annular groove or recess in which we insert a ring (or rings) of yielding
substance (preferably cork); or the ring of yielding substance may be put round
the outside of the metal face.
The seating we inake with two or more concentric annular projections or rims.

page_text: In order that the yielding substance of the valve may come into contact with its
seating just before the metallic surfaces meet, either the yielding substance or its
opposite face must project slightly; if however the cork or other yielding substance
should at any time become too much worn or otherwise give way, then the metal
face of the valve would come into contact with the other annular projection or
rim on the seating and would again shut off the gas.
It will be evident that if preferred this arrangement may be reversed, that is to
say, the valve may be made with the two or more concentric annular projections
or rims and the ring of cork or other yielding substance may be inserted in an
annular recess in or placed round the seating.

Improvements in Apparatus for Supplying Gas or other Fluid
on Prepayment.
We JOHN HAWKYARD of Shaws Lane Upper Mill Saddleworth in the County
of York, Foreman, and JOSEPH BRADDOCK, of 72 Windsor Road Oldham in the
County of Lancaster, Gas Engineer, 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 improvements upon the gas-supplying apparatus
invented by us and described in the Specification of Letters Patent granted to us
Nos. 12584, and 14655 both of the year 1890, wherein the gas supply valve is
fixed at or near one end of a spindle which is capable of an endwise and also of
revolving motion, and upon which spindle are two wheels to
a
one of which
motion is given direct from the action of the gas meter, and to the other motion is
communicated by means of the coin in the reciprocating oscillating or revolving
coin receiver the end wise motion for opening or closing the valve being given
to the spindle by an inclined plane or cam surface on one wheel acting on a fixed
projection on the other or rice versa.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a plan view of our improved apparatus, and Fig. 2 a
longitudinal section of the same.
a is the outside casing of the apparatus, the valve box, c the valve, d the
coin receiving box, and e the sliding and revolving spindle of the apparatus upon
which the wheels fand g are mounted.
According to our present invention we place the valve e outside the seating h
with its face towards the wheels above mentioned so that its closing movement.
can be obtained by a pull instead of a push or thrust, and another advantage is
thereby gained, which is that the frame a and the valve box band seating
can
be all cast in one piece if desired, and ready access may be had to the valve c
for repairs, or renewal, without disturbing the other parts of the apparatus.
We provide one of the said wheels g (as shown on the drawings) with a sloping
projection or finger i, and the other with a corresponding sloping notch or slot k,
so that when one wheel overtakes the other the side of the said sloping notch k
acting against the side of the said sloping projection (or rice versa) will thrust
the said wheels ƒ and g asunder, or draw them together, and thus open or close
the valve c by giving the requisite end wise motion to the valve spindle e, the

page_text: closing motion being given by a forward pull, and the opening motion by a
backward thrust as before described without the necessity for any spring or other
auxiliary, it being understood that the wheel g is fixed on the valve spindle e and
that the end of the latter can both slide and revolve in a hole in the boss of the
wheel, the latter being prevented from moving endwise by a loose collar l
affixed by screws m.
By preference we make the stop valve c of metal and in the face thereof we
make an annular groove or recess in which we insert a ring n (or rings) of
yielding substance (preferably cork); or the ring n of yielding substance may be
put round the outside of the metal face.
The seating h we make with an annular projection or rim *, in order that the
yielding substance n of the valve may come into contact with its seating just before
the metallic surfaces meet, for which purpose either the yielding substance or its
opposite face must project slightly; if however the cork or other yielding substance n
should at any time become too much worn or otherwise give way, then the metal
face of the valve would come into contact with the metal surface of the seating h,.
and would again shut off the gas.
C
It will be evident that if preferred this arrangement may be reversed, that is to
say, the valve may be made with an annular projection or rim *, and the ring n
of cork or other yielding substance may be placed round the seating.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that we
are aware of Patent No. 15,740 A.D. 1893 granted to Daniel Orme and referring
inter alia to the positive opening and closing of the gas supply valves of automatic
gas meters by means of a two-way cam Or its equivalent, and to the positive
closing of such valves by a cam or inclined face or its equivalent, and we do not
claim anything described and claimed in the aforesaid Specification; but what we
claim is
―
First. In a prepayment gas supply apparatus having the gas supply valve fixed
at or near one end of a spindle which is capable of an end wise and also of a
revolving motion, and upon which spindle are two wheels to one of which motion
is given direct from the action of the gas meter, and to the other motion is.
communicated by means of a coin in a reciprocating, oscillating, or revolving coin
receiver, the improvement consisting in providing one of the said wheels with a
sloping finger and the other with a corresponding sloping slot so that when one wheel
overtakes the other the valve spindle is caused to move end wise so as to either open
the valve by a direct thrusting action, or to close the same by a positive pull (as
the case may be) without the aid of any spring or other auxiliary, substantially as
hereinbefore described.
Secondly. We claim the improvements in apparatus for supplying gas or other
fluid on prepayment substantially as herein before described and illustrated by the
drawings annexed.
