I, JOHN. FREDERICK, SIMMANCE, of, No. 223 The Grove, Hammersmith, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to coin freed'meter apparatus of the kind described in the
Specification No. 1325, of 1895; the objects which I have in view. being to adapt
such apparatus to meters in which the gas valve controlled by it cannot be
conveniently arranged under the coin tube, and also to render more certain the
retention of the gas valve in an open condition while there is a coin in the tube,
whether that coin be depressed or not by the plunger. For this purpose, when
the valve cannot be conveniently arranged immediately under the coin tube, as is
generally the case in a wet gas meter, I arrange under the coin tube a sliding rod
to which is jointed one arm of a loaded or spring-urged lever which may be a bent
lever, the other arm of which is jointed to the valve stem so that the depression
of the sliding-rod by the coin causes the valve to open, and when the rod is no
longer depressed the weight or spring closes the valve. In order to retain the
valve open even when the coin in the tube is not depressed by the plunger,
according to one arrangement; I employ a pair of pawls mounted in. the tube,
differing from those described in the specification above referred to in being
pivotted on centres which are within the tube, these centres being themselves on
radius arms which are pushed aside by the passage of a coin. The pawls thus
mounted may be of considerable length and width, their faces being cut in steps
BO as to catch over one, two or a number of superposed coins.
Instead of pivotting pawls as above described, the sides of the lower part of the
coin tube may be slit and the parts between the slits bent, so that they tend by
their own elasticity to spring inwards. By cutting these parts to different lengths
and taking care that each one of a certain length, has one of the same length
opposite to it; a number of symmetrical steps are formed holding down one, two or
a number of superposed coins.
According to a modified arrangement, I provide a pawl below the revolving coin
wheel or reciprocating coin plate, this pawl being so arranged as to engage a pin
or catch on the valve stem or the rod, after it has been depressed by a coin, and in
that condition to hold'the valve open. But I provide on the coin wheel in suitable
positions studs each of which as the wheel revolves, releases the pawl when the coin
is withdrawn allowing the valve to close; and in the case of the reciprocating
coin, plate Lattach to it an arm, which in.like manner releases the pawl, and, allows
the valve to close.

I, JOHN FREDERICK SIMMANCE, of No. 223 The Grove, Hammersmith, in the
County of Middlesex,. Civil 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:--
My invention relates to coin freed meter apparatus of the kind described in the
Specification No. 1325 of 1895, the objects which I have in view being to adapt
such apparatus to meters in which the gas valve controlled by it cannot be
conveniently arranged under the coin tube, and also to render more certain the
retention of the gas valve in an open-condition while there is a coin in the tube,
whether that coin be depressed or not by the plunger. For this purpose I modify.
the apparatus as I shall describe referring to the accompanying drawings.
Figure 1 is a plan, Figure 2 is an elevation and Figure 3 is a section shewing
modifications, according to the present invention applied in conjunction with
reciprocating plate by which the coins are moved.
- Figures 4 and 5 are part sections at right angles to one another shewing a
modification applied in conjunction with the revolving coin wheel.
When the valve cannot be conveniently arranged immediately under the coin
tube, as is generally the case in a wet gas meter, I arrange under the coin tube A
a sliding rod B to which is jointed one arm of a loaded or spring-urged bell crank
lever C, the other arm of which is jointed to a valve stem D so that the depression
of the sliding rod by the coin causes the valve to open, and when the rod is no
longer depressed the weight or spring closes the valve.
In order to retain the valve open even when the coin in the tube is not depressed
by the plunger, according to one arrangement shewn in Figure 3 I employ a pair
of pawls E mounted in the tube, differing from those described in the specification
above referred to in being pivotted on centres e which are within the tube, these
centres being themselves on spring urged radius arms F which are pushed aside by
the downward passage of a coin. The pawls thus mounted may be of considerable
length and width, their faces being cut in steps so as to catch over one, two or a
number of superposed coins G.
According to a modified arrangement I provide a pawl H below the revolving
coin wheel K or reciprocating coin plate P, this pawl being so arranged as to
engage a pin or catch h on the valve stem or the rod after it has been depressed
by a coin, and in that condition to hold the valve open. But I provide on the coin
wheel in suitable positions studs L each of which as the wheel revolves acting on
a lever arm of the pawl when the coin is withdrawn releases the vertical rod
allowing the valve to close; and in the case of the reciprocating coin plate I attach
to the plate an arm M which in like manner releases the pawl and allows the valve
to close.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim in respect of coin freed meter apparatus of the kind described in the
Specification No. 1325 of 1895 is :-
1. For adapting the apparatus to wet meters the combination of a vertical rod
under the coin tube, a loaded or spring urged bell crank lever with the valve stem
substantially as described.
2. For retaining the valve open while any coin remains in the coin tube, a pair of
stepped pawls pivotted within the tube or spring urged radius arms, substantially as
described.

page_text: 3. In combination with the vertical rod which works the valve a catch and paw),
and studs on the coin wheel or an arm of the reciprocating coin plate arranged to
release the catch, substantially as and for the purpose set forth.
Dated this 6th day of November 1896.
