66 Improvements in and connected with the Mechanism of Coin Freed
Gas or other Fluid Meters."
We RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, of the firm Thomas
Glover and Company Limited 214 to 222 St. John Street, Clerkenwell, London.
Gas Meter Manufacturers do hereby declare the nature of this invention to be
as follows:-
This invention relates to a particular construction and arrangement of valve
operating appliance for use in conjunction with the usual coin actuated apparatus
and the internal meter mechanism with and by which it is connected and operated
to admit the flow and automatic stoppage of gas or other fluid after the insertion
of a coin and at the same time indicate to a consumer in a direct and unequivocal
manner the amount of gas prepaid or remaining unconsumed.
In carrying the invention into practice we employ a spheroidal screw preferably
horizontally mounted upon or forming part of a rod or shaft carried in suitable
bearings which may upstand from a box or casing containing the valve by which
the flow or stoppage of the gas is effected.
An internally and externally toothed (planetary) ring of given diameter having
dished arms and pivotal collar surrounds the before mentioned spheroidal screw
under the horizontal shaft and is so mounted that it is revolvable by the engage-
ment with the external teeth of a worm under the action of the internal mechanism
to and by which the said worm is connected and operated.
A toothed pinion is arranged between the spheroidal screw and the planetary
ring and engages or is in gear with the screw and the internal teeth of the ring;
said pinion is pivoted to and freely revolvable upon a curved arm the boss of
which is connected to a spindle passing through the pivotal collar of the
planetary ring and a stuffing box and gland to the interior of the valve box, said
spindle at its lower end carrying the valve for closing the inlet or outlet to or
from the said box to the meter bellows or consumers pipes.
A pointer is attached to the pivot carrying the pinion and when in action moves
over the indices of a dial a radial distance actually corresponding with the radial
imovement of the valve said movement being plainly visible through a suitable
opening provided in the meter case.
In action the turning of the spheroidal screw rotates the engaging pinion
thereby causing it to work circumferentially over the internal teeth of the planet-
ary ring or wheel and imparting a radial movement to the curved arm and valve
arm attached to the lower end of the spindle and thus allow the gas to flow.
The worm operated by the meter mechanism revolves the planetary ring by its
engagement with the external teeth and causes the pinion to rotate and walk
back over the spheroidal screw and close the valve the amount of said movements
being made directly apparent to the consumer by the pointer and dial before-
mentioned.

We, RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, of the firm Thomas
Glover and Company, Limited 214 to 222 St. John Street, Clerkenwell, London.
Gas Meter Manufacturers. 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 a particular construction and arrangement of valve
operating appliance for use in conjunction with the usual coin actuated apparatus
and the internal meter mechanism with and by which it is connected and operated
to admit of the flow of Gas or other fluid after the insertion of a coin, and to
effect an automatic stoppage of such flow after the predetermined quantity has
passed through for consumption proportionately to the number of coins so inserted,
and at the same time indicate to a Consumer in a direct and unequivocal manner
the amount of Gas prepaid or remaining unconsumed.
In carrying the invention into practice and as we show on the annexed
drawings of which Figure 1 is plan, Figure 2 side elevation of Gas Meter with
our invention applied. Figure 3 detached plan of internal and external toothed
wheel. Figure 4 detached view of valve lever and pinion. Figure 5 plan of
valve box, we employ a spheroidal screw A preferably horizontally mounted upon
or forming part of a rod or shaft B carried in bearings C which may upstand
from a box or casing D, part of which contains the valve E by which the flow
or stoppage of the Gas is effected.
An internally and externally toothed (planetary) ring F of given diameter
having dished arms G, G, and pivotal collar H surrounds the before mentioned
spheroidal screw A under the horizontal shaft B and is so mounted that it is
revolvable by the engagement with the external teeth I of the planetary ring F
with the worm J under the action of the Meter mechanism K by which the said
worm Jis operated through the pinion L.
A toothed pinion M on a bracket N is arranged between the spheroidal screw A
and the planetary ring F and engages or is in gear with the screw A and with
the internal teeth P of the ring F, said pinion M is pivotted to and freely.
revolvable upon a curved arm Q, the boss of which is connected to a spindle R
passing through the pivotal collar H of the planetary ring F. and a stuffing box
and gland S to the interior of the valve box T, said spindle at its lower end
carrying the valve E for closing the inlet to or outlet from the said box T to the
Meter bellows or Consumers pipes.
A pointer U is in connection with the pivot carrying the pinion M by the
rodsband when in action moves over the indices of a dial a distance actually
corresponding with the movement of the pinion M and valve E, said movement
being plainly visible through a suitable opening provided in the meter case.
In action, the turning of the spheroidal screw A from outside Meter after inser-
tion of a coin into the apparatus as described, say, in the Specification of our
former Patent No. 22830 of 1894, rotates the engaging pinion M thereby causing
it to walk circumferentially over the internal teeth P of the planetary ring or
wheel F and imparting a movement to the curved arm Q and valve arm V
attached to the lower end of the spindle R and thus allow the Gas to flow. The
worin Joperated by the Meter mechanism revolves the planetary ring F by
its engagement with the external teeth I and causes the pinion M to rotate and
walk back over the spheroidal screw A and close the valve E the amount of said

page_text: movements being made directly apparent to the Consumer by the pointer U and
dial before mentioned.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. The hereinbefore described improvements in and connected with the
mechanism of coin freed. Gas and other fluid Meters and specified under the
letters of reference shown on the annexed drawings, all the parts or appliances
being arranged for action, substantially as represented.
2. In a Coin freed Gas or fluid Meter, a rotatable spheroidal screw A for moving
a pinion M in gear therewith over internal teeth of a stationary planetary ring
wheel F to open the passage valve E, the closing of such valve E being effected
by the Meter mechanism through its worm J acting in the external teeth of the
planetary ring wheel and thence as the moving body through its internal teeth
to rotate the pinion M over the fixed spheroidal screw, as set forth.
