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:-
The object of this invention is an improved gear for coin freed apparatus for the
sale of gas.
For the purpose of our invention, we mount a couple of screw rods upon axles
having separate motions imparted to them by the money receiving appliances and
by the meter mechanism respectively. The two screw rods are arranged end on
to each other and carried by suitable bearings. Each of these screw rods has a
pinion in gear, both being connected to the gas valve rod or lever. The pinions
are also in gear with each other.

proval 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 and in
what manner the same is to be performed to be particularly described and.
ascertained in and by the following statement :-
The object of this invention is an improved gear for coin freed apparatus for the
sale of gas.
For the purpose of our invention, we mount a couple of screw rods upon axles
having separate motions imparted to them by the money receiving appliances and
by the meter mechanism respectively.
The two screw rods are arranged end-on to each other and carried by suitable
bearings. Each of these screw rods has a pinion in gear, both being connected to
the gas valve rod or lever.
The pinions are also in gear with each other, and when one is rotated the other
rotates also but as the other rod is stationary that pinion simply walks over it as on
& rack.
As a modification of the foregoing, the two screw rods may be in the form of flat
discs with a screw thread upon a face of each for the two geared pinions to engage
and be rotated by either disc, one, i.e., the opposite pinion, to walk over the
stationary disc as on a rack, the valve being acted upon in a manner already
mentioned.

page_text: Our invention will be well understood by inspection of the annexed drawings in
which at Figure 1 an elevation at right angles to that shown at Figure 2. Figures 3
and 4 show a modification of the foregoing.
A, B, are two independent axles mounted to revolve in bearings or frame C, the
axle A is rotatable by a crank handle or button head from outside a meter casing
and the axle B by the meter mechanism which acts on the wheel D.
E, F, are two screw threaded rods on the axles A, B, and G, H, are two pinions
in gear with each other and also with the two screw threaded rods E, F. The
pinions G, H, are held in position with relation to each other and with the
rods E, F, by centre pins I, J, in the slot of a sliding bar K, to the end L of
which the gas valve of the meter is directly secured or to rods as desired for
actuating said valve.
In action, suppose a coin to be inserted into the slot of a coin freed meter or
price changer inventions such as set forth in our previous Letters Patents
Nos. 674, 6058, 8327, 22830, 25272 of the year 1894, and 16271 of the year
1895, the coin becomes locked in the tooth of a wheel while in the receiving
pocket, so that on a handle or knob being rotated a given distance, the coin forces
the notched or toothed wheel which is on the axle A of the screw E round a
corresponding distance, this in its turn gives rotation to the pinion G and by G to
pinion H which by said movement only walks over the stationary screw F as on a
rack, the bar K being likewise moved to open the gas valve for How.
The coin now automatically falls or is discharged and breaks the connection
between the handle and the axle A, so that the handle can so to speak be played
with, without affecting the apparatus unless a fresh coin be inserted for a repeat
operative motion, the action of the meser mechanism now operates the wheel Dand
axle B this causes the screw rod F to turn the pinion H to draw back the rod K
for closing the valve and so shut off the flow. This rotation of the pinion H also
rotates the pinion G which now walks along the screw rod E as on a rack and
recovers its first position ready for a repeat action by the screw rod E after a fresh
coin is inserted and the handle and notched wheel are turned.
The important feature in this invention is:-Two screw threaded bodies
arranged end-on to each other in a frame, but in connection by two pinions which
are also in gear with themselves as shown on the drawing for actuating a gas valve
of a coin freed gas meter.
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 construction, arrangement, and operation of appliances as described and
fitted end-on to each other as shown on the annexed drawings, as a means for
opening and closing the valve of a coin freed gas meter.
2. In gas meter coin freed mechanism, the combination and operation of two
screws end-on with each other and in gear with two pinions which are also in gear
with themselves, and operable from either screw while the second of the two
pinions can walk over the non-rotated screw as on a rack, as described, and as and
for the purpose set forth.
