Improvements in and connected with Mechanism for Obtaining
Reciprocating Motion.
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 in its application relates more particularly to its use in connection
with the valve of coin freed gas meters, but generally the mechanism is for obtaining
a reciprocating motion.
For this purpose we preferably employ two screwed rods arranged in such
relation to each other that two wheels fixed to the end of an arm may gear there-
with the said arm being free to rotate in a pivot which is free to turn by the radial
movement imparted to the arm by turning either of the screws.
The rotating and radially moving arm is turned and moved in one direction
under the action of one screwed rod and is turned and moved in the reverse
direction under the action of the other screwed rod and by this means the pivot
in which the arm rotates is caused to oscillate through a given are thereby
affording the necessary motion from and by which a reciprocating action is
obtained.
Or the reciprocating motion may be obtained from the reversing radial move-
ment of the arm to which the worm wheels are affixed.
In order that the worm wheels may gear equally in the worm of the screwed
rod throughout the radial movement of the arm we may curve said screwed
rods.
When applied to the valve of a coin freed gas meter one end of the oscillating
pivot is directly connected to the valve arm to be operated.

Improvements in and connected with Mechanism for Obtaining
Reciprocating Motion.
We, RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, trading as
Thomas Glover and Company, of 214 to 222 St. John Strect, 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:-
This invention in its application relates more particularly to its use in connection
DI

page_text: with the valve of coin freed gas meters but generally the mechanism is for obtaining
a reciprocating motion.
For this purpose we employ two screwed rods arranged in such relation to each
other that two wheels fixed to the ends of an arm may gear therewith, the said arm
being free to swing in a pivot and to turn by a radial movement imparted to the
arm by turning either of the screws.
The pivoted arm is moved in one direction under the action of one screwed rod
and is moved in the reverse direction under the action of the other screwed
rod and by this means the arm oscillates through a given arc thereby affording the
necessary motion from and by which a reciprocating action is obtained.
Or the reciprocating motion may be obtained from the reversing radial move-
ment of the arm to which the worm wheels are affixed.
In order that the wheels may gear equally in the worm of the screwed rod
throughout the radial movement of the arm we may curve said screwed rods.
The invention will be clearly understood by reference to the annexed drawings.
Figure 1 plan of two plain screw threaded rods arranged axially parallel to each
other and with pinions in gear from a pivot on which the arm carrying the pinions
is free to oscillate.
Figure 2 detached view of one of the pinions and the pivot, here shown as a pin
which moves with the arm.
Figure 3 plan of two screw threaded rods each of barrel or double convex
shape in their length with the pinions movable on and by the outer or bulged
edges.
Figure 4 section of same through the line a, a.
Figure 5 plan of two parallel screw threaded rods of concave shape in their
length and having the two pinions in gear with the inner concave edges.
Figure 6 section of same through the line b, b.
The same letters refer to like parts in all the figures.
A, A, are the two screw threaded rods held in a frame B, B, for maintaining
their parallel position to each other. They are mounted loosely in the frame and
are free to rotate in same. The frame is secured to any desired part of an
apparatus. C is a standard or bracket localizing a pivot pin D centrally between
the two screw rods A, A, and this has a sleeve arm E affixed.
F, F, are studded or other pinions or parts of pinions on each end of spindle E¹
free to rotate in said arm E and in gear with both screw rods A, A, in such
manner that when either of the axles G, G, is turned to revolve its screwed rod A,
the pinion in gear therewith is caused to rotate over the arc of a circle as indicated
by the dotted lines, the other pinion being also caused to rotate and walk over the
other or stationary screw rod of the pair. The arm E maintains the relative
position of both pinions during this movement by riding on or moving with the
pivot D.
The lever or connecting rod shown by the line H for moving say the valve H¹
of a gas meter over or off and on the gas passage (inlet or outlet) can be affixed or
jointed to the swinging arm E at any distance from the pivot point as can be
gathered by the arrangement shown at Figures 1 and 5, according to the distance
the valve has to be moved, or it may be actuated direct from a movable pivot pin,
as at Figure 6.
In some cases, particularly when the pinions are operable from a distance, as at
Figures 3 and 4, the axles of said pinions may be held in sleeves I, 1, and by
bevil gear J, J, and a transverse shaft K they can be put in balance and thus
relieve any strain that the swinging arm E might otherwise have to bear, it being
essential that friction be reduced as much as possible.
We have particularly referred to the fixing of our invention to coin freed gas
meters but it is or can be made applicable for other coin freed apparatus, the
principle feature being the reciprocation of a rod such as H by the swing action of
a pivoted arm E with pinions F F radially operable alternately from screw
threaded rods A A.

page_text: 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 herein before described means and appliances by which reciprocating
motion can be obtained.
2. The several arrangements of apparatus shown on the annexed drawings
whereby opposite movements of pinions by their connection to a swing arm from a
mid pivot can be transmitted to a rod or lever for reciprocating motion thereof,
the pinions or their equivalents being operable from either of two parallely
arranged screw threaded rods, as set forth.
