Improvements in Coin Freed Gas Meter Apparatus.
I, JOB GOULSON of The Imperial Continental Gas Association, Gitschinerstrasse,
21 Berlin, S., Meter Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus which on the introduction of a coin of certain
value opens a valve so as to start the meter and maintain it in action for a time while
it delivers a quantity of gas equivalent to the value of the coin or of a number of coins.
successively introduced at a slot provided to receive them.
For this purpose there is mounted in a casing having a slot at the top a wheel
having in its periphery a slot about half the width of the coin, and facing it another
wheel having a similar slot. The first wheel can be turned by a handle without
moving the second wheel, but on a coin being inserted so as partly to occupy both
slots, on turning the first wheel half round, the second wheel is also turned half round,..
and the coin drops out into a receptacle below. A number of coins may be thus
introduced in succession, the second wheel making half a revolution for each coin
introduced. This second wheel is geared to a screw spindle the nut on which, when
the meter is inert, bears upon and keeps closed the gas valve. But when the screw is
turned the nut is moved from the valve allowing it to open admitting gas to the meter
which then works delivering gas. The counter mechanism of the meter is connected
by suitable gear to a pinion having long teeth which are engaged by teeth on the
periphery of the nut, and thus as the counter mechanism revolves the nut is turned
back and moves along the screw spindle until it again reaches the gas valve and closes
it stopping the meter. As the distance which the nut has thus to move along the
screw spindle is proportional to the number of coins that had been introduced, so the
number of revolutions of the counter mechanism and therefore the quantity of gas
delivered is proportional to the number of coins. In order to provide for variations
in the price of gas, the gearing by which the long toothed pinion is connected to the
counter mechanism is suitably altered.

I, JOB GOULSON, of The Imperial Continental Gas Association, Gitschinerstrasse,
21 Berlin, S., Meter Maker, do hereby declare the nature of this invention, and in
5 what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to apparatus which on the introduction of a coin of certain
value opens a valve so as to start the meter and maintain it in action for a time while

page_text: it delivers a quantity of gas equivalent to the value of the coin or of a number of coins
successively introduced at a slot provided to receive them.
I shall describe apparatus according to my invention referring to the accompanying
drawings.
Figure 1 is a front view partly sectional,
Figure 2 is a plan on the line 2-2 Figure 1, and
Figure 3 is a vertical section on the line 3-3 of Figure 1.
A part external front view is shewn by Figure 4.
In a casing A having at its top a slot a adapted to receive the coin is mounted
a wheel B having on its periphery a pocket 6 adapted to take about half the width of
the coin, and another wheel C having two pockets c opposite to one another. The
wheel B can be turned by a handle & without moving the wheel C but on a coin being
inserted so as to occupy the pockets of both wheels, then on turning the wheel B half
round, the wheel C is also turned half round, and the coin drops out into a receptacle D
below. A number of coins may be thus introduced in succession, the wheel C making
half a revolution for each coin introduced. This wheel C is geared to a screw
spindle E, the nut e on which, when the meter is inert, bears upon a lever F and
keeps closed the gas valve G. But when the screw E is turned by the revolution
of C, the nut e is moved from the valve lever allowing the valve G to open admitting
gas to the meter which then works delivering gas. The counter mechanism of the
meter is connected by suitable gear H and h to a pinion K having long teeth which
are engaged by teeth on the periphery of the nut e. As the counter mechanism
revolves the nut e is turned back and moves along the screw spindle E until it again
reaches the gas valve lever and closes the valve stopping the meter. As the distance
which the nut bas thus to move along.the screw spindle is proportional to the number
of coins that had been introduced, so the number of revolutions of the counter
mechanism and therefore the quantity of gas delivered is proportioned to the number
of coins. In order to provide for variations in the price of gas, the gearing by
which the long toothed pinion is connected to the counter mechanism is suitably
altered.
The handle is preferably shaped as an index, being always brought to the
position shown in Figure 4 when a coin has to be introduced. The nut e is
preferably grooved to receive the fork of a pointer I which projects through a slot i
graduated at the side to shew the amount of gas still to be consumed until after
a certain number of coins have been introduced.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. Coin freed gas meter apparatus constructed and operating substantially as
described with reference to the drawings.
2. In apparatus such as is above referred to, the combination of the screw E turned
as coins are introduced, its nut e bearing on the valve lever F and gearing with the
long pinion K turned by the counter gear of the meter, substantially as described.
