Improvements connected with the Mechanism of Coin Freed Gas
Meters for Coins of Different Values.
We, RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, of the Firm Thomas
Glover and Co. Ld., 214 to 222, St. John Street, Clerkenwell, London, Gas
Meter Manufacturers, do hereby declare the nature of this invention to be as
as follows;-
This invention has for object, utilising intercepting mechanism in such manner
in coin freed gas meters, that coins of different values (say, two) may be inserted
in their respective receivers and the original mechanism be actuated thereby
to effect the opening or movement of the gas inlet valve proportionately to the
value of the coin or coins so inserted.
As an example of our invention, referring to our previous Patent No. 22830
dated 24th November 1894, in which two parallel screw threaded rods have a
pinion in gear with each, so that one is turned after receipt of a coin to open
the gas valve, and the other turned by the meter mechanism to close the valve.
In connection with such mechanism or any other to which our improvements
are applicable, we mount on one of the rods an extra pinion which through an
intermediate or idle gear, motion can be given to it from the second or indepen-
dent shaft of the second coin receiver apparatus, the extra pinion having in
conjunction a bevel gear for operating a circular travelling idle bevel wheel
which is also in gear with a second bevel wheel forming part of the pinion of
the meter operating shaft which closes the valve.
The circular travelling bevel wheel is idle in either direction, i.e. it walks
over or around the teeth of stationary pinions' bevel and through it by the
operation of the coin receiver, the valve can be opened further, to a distance
corresponding to the quantity of gas to be delivered. Thus, say, a penny or
a halfpenny can be placed in their respective slots, and on the handle being
operated, the one valve of the meter can be opened to the allotted extent accord-
ing to the value of the coin so inserted.

page_text: 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 has for object, utilizing intercepting mechanism in such manner
in coin freed gas meters that coins of different values (say two) may be inserted
in their respective receivers and the original mechanism be actuated thereby
to effect the opening or movement of the gas inlet valve proportionately to the
value of the coin or coins so inserted.
As an example of our invention referring to our previous Patent No. 22830
dated 24th November 1894 in which two parallel screw threaded rods have a
pinion in gear with each so that one is turned after receipt of a coin to open
the gas valve and the other turned by the meter mechanism to close the valve.
In connection with such mechanism or any other to which our improvements
are applicable we mount on one of the rods an extra pinion which through an
intermediate or idle gear motion can be given to it from the second or indepen-
dent shaft of the second coin receiver apparatus the extra pinion having in
conjunction a bevil gear for operating a circular travelling idle bevil wheel
which is also in gear with a second bevil wheel forming part of the pinion of
the meter operating shaft which closes the valve.
The circular travelling bevil wheel is idle in either direction i.e., it walks
over or around the teeth of stationary pinions bevil and through it by the
operation of the coin receiver the valve can be opened further to a distance
corresponding to the quantity of gas to be delivered.
Thus say a penny or a halfpenny can be placed in their respective slots and
on the handle being operated the one valve of the meter can be opened to the
alloted extent according to the value of the coin so inserted.
Our invention is shown on the annexed drawings.
Figure 1, plan of the apparatus with the top or cover of a gas meter removed.
Figure 2 front view of the upper part of a gas meter with two price changer
face plates in position for say a penny and a halfpenny respectively.
The price changer front plates and the rear appliances connected therewith
for the reception and utilization of either coin are the same as those described
in our previous Patent No. 25272 dated 29th December 1894 and need no
detailed description. The two parallel screw threaded rods with the pinion in
gear are also protected by our former Patent No. 22830 of the year 1894 and are
fully described in the specification of said patent we therefore only now describe
them with reference to our present invention which consists in providing a half
or any value coin receiver and actuating shaft A about horizontal and parallel
in position to that of the full value coin receiving or actuating shaft B. The
shaft A has on its inner end a toothed wheel C in gear with an idle wheel 1 both
being carried by the same bracket or bearing E. This idle or intermediate
wheel I being also in gear with the toothed wheel F mounted loosely upon the
shaft G for rotating it in conjunction with the bevel wheel F" as part of same;
said bevel wheel by action on the traveller pinion gear H causes the wheel H
to rotate and by its being carried by a sleeve I fixed on the shaft G so that it
not only has a rotation but a travel around the shafts axis and in such motions
ensures the rotation of the screw threaded portion G' in the same direction as
would happen to the screw threaded portion B' if the shaft B has been acted
upon after the receipt of the full value coin the bevel wheel J remaining sta-
tionary so that the wheel H simply walks around the wheel J without affecting
it in any way.
The movement of the screw G¹ causes the pinion K to rotate and move by
its bar L the gas valve M to open it to a greater distance proportionate to the
value of the inserted coin.
The bevel wheel J also mounted loosely on the shaft G is in a piece with the
toothed wheel P which receives its motion from the worm Q this being fixed

page_text: on the index or registering spindle R for transmitting the motion of the bellows
mechanism through the gears S, T, in the usual manner during the consumption
of the gas, the toothed wheel P and bevel wheel J being then rotated and acting
upon the sleeve pinion H to cause the sleeve I and consequently the shaft G
to reverse its direction of travel and the valve M to be gradually moved to close
the passage for
gas by the back travel of the pinion the bevel wheel F and
the pinion F being then stationary so that the wheel H simply walks around F
without affecting it in any way.
U, U, are the usual link appliances which are caused to travel round the
pivot of the arm W in a well known manner. X spindle of quantity recorder Y
operated by pinion Z in gear with rack on bar L.
Supposing the appliances or mechanism he prepared for a penny and a half-
penny respectively a penny coin could be inserted through the slot a Figure 2,
or a halfpenny through the slot b. Then by turning the handle or knob
or el
as the case may be until the coin is forced against a fixed stop for its arrest and
automatic discharge.
dis a locked bar placed across the face plates of the price changers e, f, to
prevent or check the removal of the face plates e, f, except by a responsible
official.
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. In a coin freed gas meter the means or appliances by which a full or a half
or any value coin can be utilized for giving motion to the gas valve the action
of or from either coin having effect upon the pinion K as specified and substan-
tially as shown.
2. In a coin freed gas meter the arrangement of the gear C, D, F, FI, H, J, P,
as shown in combination with sleeve I fixed on shaft G and acting in the manner
and for the purposes set forth.
3. The sleeve I fixed on shaft G and carrying a rotative and traveller wheel H
for positive operation by the wheel F for opening the gas valve after receipt
of a half or other value coin and a reverse positive operation by wheel J by the
meter mechanism through the gas consumption as specified.
4. The employment of the gas meter operative mechanism as a means for
opening the gas valve after receipt of half or any other value coin substantially
as described.
5. The compounding of reciprocating motions for coin freed gas meters by
any means of adding to the time value to the working off portion of reciprocat-
ing motions by the meter mechanism, substantially as described and represented.
