Improved Gear for Coin Freed Apparatus for the Sale of Gas.
We RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER trading as
Thomas Glover and Company, of 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 consists of two arms or levers each pivoted at one end to a plate,
and the other ends connected by a bar or link. One of the pivots in the plate can
be attached to the coin actuating apparatus and the other to the meter mechanism
and the motions obtained therefrom causes the connecting link or bar to move in a
parallel manner by the following novel arrangement, viz. A wheel or pinion is fixed
at each pivot around which the arms or levers before mentioned can move freely
and these pinions gear into two wheels pivoted to the opposite ends of the levers or
bars. The wheels are of such diameter that they also gear into each other so that
when either pinion is turned it rotates the wheel into which it gears and by this
means causes said wheel to travel around the other wheel and pushes the connecting
link along to obtain a motion for opening or closing a valve or for any other
required purpose.

We, RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, trading as
Thomas Glover and Company, of 214 to 222 St. John Street, Clerkenwell,
London, Gas Meter Manufacturers, do hereby declare the nature of this inven
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:―
of
This invention relates to improved gear for coin freed apparatus for the sale
gas.
The invention will be clearly understood by reference to the annexed drawings.
Figure 1 sectional elevation of the upper or gear chamber of a gas meter.
Figure 2 an edge view of the gear, and
Figure 3 a plan of the gear chamber with the cover removed with the gear for
opening valve after receipt of coin and of gear for closing the valve by the meter
mechanism.
Figure 4 is a reverse side elevation of the gear with part of frame broken away
to show connection of pinions with wheels.
This invention consists of two arms or levers A, B, each pivoted at one end to a
plate C and the other ends connected by a bar or link D.

page_text: move.
One of the pivots, say A in the plate C can be attached to the coin actuating
apparatus of any kind, and the other, say B to the meter mechanism and the
motions obtained therefrom causes the connecting link or bar D to move in a
parallel manner by the following novel arrangement viz.: A wheel or pinion E, F,
is fixed at each pivot around which the arms or levers A, B, before mentioned can
e freely and these pinions E, F, gear into two wheels G, H, pivoted to the
opposite or free ends of the levers or bars A, B. These wheels are of such
diameter that they also gear into each other as indicated, so that when either
pinions E or F is turned it rotates the wheel G or H, into which it gears and by
this means causes said wheel to communicate its motion to the other wheel and
each to travel around its own pinion and thereby pushing the connecting link D
along to obtain a motion for opening or closing a valve or for any other required
purpose.

We attach a valve rod preferably to the farther lever such as A from the
valve J which said lever may operate direct or through crank or other arm say
that marked K. One pivot say that with the lever A may have a pinion or mitre
wheel L on it for gearing into the pinion M which by the spindle N can turn the
indicator finger P to show on its dial the quantity of gas left to be consumed at
any time supposing a number of coins had been placed in the trap or slot of the
coin receiving apparatus which for the time forms part of the coin freed meter.
In Figure 3 we have shown our previously patented coin receiver as described in
our Specification of No. 25272 A.D. 1894 but the present invention is applicable to
any system of coin receiving apparatus direct or by a slight modification of the
attachment appliances.
The
By reference more particularly to Figure 1 of the drawings annexed hereto it
will be understood that for each predetermined coin inserted in the casing the
handle or knob R is rotated a defined arc of a circle in accordance with the
quantity of gas allowed as value for each coin. This handle or knob R moves (by
the coins contact with the mechanism in the casing Q) the shaft axially arranged
therewith, this then turns the pinion E and under gear wheel L, spindle N, and
the finger P indicates said movement for the satisfaction of the consumer.
pinion E siniultaneously by being in gear with the wheel G causes it to move
round and this being in gear with the wheel H said wheel is rotated also to a
corresponding distance, and both of them move round their respective pinions and
by their connection with the link D causes their centres to maintain a parallel
position. By this means at each turn of the handle or knob R with the coin in
gear casing Q, the pinion E turns wheel G and in so turning rotates wheel H
which although in gear with pinion F only walks round it without imparting any
rotatory motion thereto, said pinion F being under control of the meter
mechanism a, b, c, d, and e and operable only during consumption of gas.
During the motion before mentioned from the fact that the wheels G, H, are
pivoted to the free ends of the levers A, B, only, it follows that the levers by the
link connection D are likewise moved and by the attachment of the rod I the
valve J is opened for flow of gas into the meter from the main.
So soon as consumption commences, the meter mechanism a, b, c, d, and e begins
and causes the pinion F to turn and this through the wheels H, G, to turn also
but in the reverse direction, the pinion E being stationary and locked allows the
wheel G to walk round without imparting any motion to it, the movement of the
wheels G, H, by the locked position of the pinion causing the link D to travel and
with it the rod I and so close the valve J. This happens however only gradually
and finally at the complete reverse movement of the mechanism effected after the
first inserted coin, the value of which in gas is then accounted for.
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 :-
The improved coin freed gas meter gear hereinbefore described and represented

page_text: in the annexed drawings, the speciality of this invention being identified by the
letters A, B, D, G, H, operable in the manner set forth for reciprocating or
oscillatory motion from pivot gears E, F, as indicated.
