PROVISIONAL SPECIFICATION.
Improvements connected with Dry Gas Meters.
I, JOHN REGINALD SCHREINER, of 43 St. Pauls Road, Canonbury, County of
London, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention relates to Improvements connected with Dry Gas Meters, the
object being to reduce the size of such meters, without diminishing cubical capacity
for the inflow and outflow of gas, or in any way interfering with the ordinary
registering valve appliances, or diameter of pipes, in proportion to the number of
lights for which such meter is prepared.
The invention consists mainly in the bellows, and for that purpose I affix the
leather diaphragms to rings of different diameters, so that the smaller can enter
within the larger and enable a maximum of travel from either side instead of a
limited travel to and from the fixed portion, as at present.
The leather diaphragms can be clipped at the edges to the rings, or otherwise
secured.
The metal, or other plates forming the backs have jointed links in connection
with kinked, or bent wires as supports, and to ensure the free movements of the
diaphragms without chance of buckling, or of becoming distorted.
By this invention, a 20 light meter need only be the size, of say, a 5 or a 10, and
in consequence the weight and bulk of material is considerably reduced as well as
the cost of production.

Improvements connected with Dry Gas Meters.
1, JOHN REGINALD SCHREINER, of 43 St. Pauls Road, Canonbury, County of
London, 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 :-
This invention relates to Improvements connected with Dry Gas Meters, the
object being to reduce the size of such meters without diminishing cubical capacity
for the inflow and outflow of gas, or in any way interfering with the ordinary
registering valve appliances, or diameter of pipes in proportion to the number of
lights for which such meter is prepared.
For the purpose of this invention, I affix the leather diaphragms to rings of
different diameters, so that the smaller can enter within the larger, and enable a
maximum of travel from either side instead of a limited travel to and from the fixed
portion as at present.
The leather diaphragms can be clipped at the edges to the rings, or otherwise
secured.
The metal or other plates forming the backs have jointed flag links in connection
with kinked or bent flag wires as supports, and to ensure the free movements of the
diaphragms without chance of buckling, or of becoming distorted. The kinked or
bent flag wires operate the registering or index mechanism.

page_text: By this invention, a 20 light meter need only be the size of say a 5 or a 10, and
in consequence the weight and bulk of material is considerably reduced as well as
the cost of production without in any way restricting the motion of the moving
parts for the regular pulsations of the bellows, or of the index appliances.
The invention will be well understood by reference to the annexed drawings.
Figure 1 is a front elevation of a meter with the lower front part of the casing
removed, and showing one of the bellows, flag, and kinked or bent axle shaped
flag wire.
Figure 2 is a part sectional plan with the kinked or bent axle like flag wire in
position when the bellows is closed, and Figure 3 a similar view with the bent axle
like flag wire in position when the bellows is extended.
The casing of the meter, the registering devices, valve mechanism, and gas
passages may be similar to those of ordinary meters, my invention having no
reference to these parts of the meter.
A represents the central partition, separating the two bellows chambers, and to
each side of this partition is secured the larger ring B of a measuring bellows C,
the inner edge being secured to the ring B by an outer wrapping a of cord in the
usual manner. D is the outer disc of the bellows carrying the outer ring but this
ring is less in diameter than the ring B of the bellows, and the outer portion of
the bellows leather C is turned inward and secured to said outer ring by a
wrapping which is within the bellows instead of on the outside as usual. By
reason of the fact that the outer ring D is less in diameter than the inner ring B
of the bellows, said outer ring can pass within the inner ring when the bellows is
compressed, and by reason of the fact that the outer portion of the bellows leather
is turned inward before being secured to the ring this entering of the outer into the
inner ring of the bellows is effected without undue wrinkling or distorting of the
bellows leather, moreover the inward bend of the outer edge of the bellows
leather serves to prevent the leather from buckling inward on the compression of
the bellows.
The use of one ring of less diameter than the other ring may however be resorted
to even if the ordinary method of securing the bellows leather by an external
wrapping is adopted, and if desired, the arrangement of large and small rings may
be reversed, that is to say, the inner ring may be the smaller and the outer ring
may pass over the same on the compression of the bellows.
By permitting one ring of the bellows to pass within the other, the maximum
degree of compression of the bellows is ensured, and in order to permit of the
maximum expansion of the bellows, I locate the "flag wire" E laterally beyond
the limits of the outer disc F of the bellows, so that it will not interfere with the
outward movement of said disc, and in order to still further remove said ".
wire "E from liability of contact with the bellows, I bend the central portion of
"flag
said "flag wire" into a different plane from the pivotal end portions, as shown.
The "flag wire" is connected by the arm or flag G and pivot stem H to the
lugs c, c, on the outer disc F of the bellows and serves to transmit the movement of
said disc to the registering mechanism at the top of the meter.
it
As the disc of the bellows moves outward therefore the "flag wire" turns on its
axis so as to bring the cranked portion of the same to the front, and thus
so much further out of the path of the expanding bellows.
carry
By thus providing for extremes of compression and expansion of the bellows it is
possible in a given size of meter to materially increase the capacity of the same, as
compared with a meter constructed in the ordinary manner.
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 is :-
1. The combination in a gas meter of the measuring bellows C, the "flag wire" E
having upper and lower bearings located laterally beyond the limits of movement
of the outer disc of the bellows, said "flag wire” É being cranked in that portion

page_text: which is between its bearings, and an arm or flag G secured to the cranked portion
of the flag wire E, said arm extending laterally across the face of the outer disc of
the meter, and being connected at its inner end to the pivot H, substantially as
specified and represented.
2. In combination with a reduced dimension dry gas meter as above set forth, the
bent axle like flag wire E, and its direct connection with the disc F by the flag G,
as and for the purposes described.
