I EDWARD FISHER BAMBER of 6 St. Swithin's Lane in the City of London, Civil
Engineer, do hereby declare the nature of this invention to be as follows :-
The machinery of the automatic counter is contained in a small box or case which
is attached to the side of the box, tray bucket or other apparatus, the number of
whose movements it is required to register. When the tray, box bucket or other
apparatus to which it may be applied is in the horizontal or in the tilting position,
the counter being fixed to it is moved into the same position. The counter is worked
by a weighted pendulum, having a ratchet attached to the top end of it, which catches
a toothed or ratchet wheel. When the weighing tray or other apparatus to which
it may be applied is horizontal, the pendulum is at rest in the perpendicular position,
but when tilted the weighted pendulum and ratchet move, and cause the toothed
wheel to revolve, and a pawl prevents the wheel from running back, when the tray
returns to the horizontal position. This motion causes the pointer or hand attached
to the axle of the ratchet wheel to move one. Another toothed wheel with a
pointer or hand on its axle is so placed that when the first wheel has made one
revolution, a pin on it catches a tooth in the second wheel and makes it move on
one. The second wheel is also supplied with a pawl, so that when the first wheel is
moving at each motion of the tray or other apparatus to which it may be applied,
the second wheel remains motionless, until the pin of the first wheel catches it
again. If necessary more wheels and pointers can be added and each complete
revolution or each motion can if desired be marked by the stroke of a hammer on
a bell. Two or more dials are provided which are divided into the same number
of parts as the number of teeth on the wheels, as the wheels revolve, the pointers

page_text: attached to their axles point to the figures on the dials. To prevent the pendulum
from jumping, and thus moving the ratchet and ratchet wheel, or from being
affected by any jerking action, a catch is supplied which prevents the pendulum from
moving backwards when the tray or box is tilted. The catch may be applied to either
the top or the bottom of the weighted pendulum or elsewhere. The catch or stop is
worked by a second pendulum, which so acts that it removes the catch or stop, as
the box or tray removes to the horizontal position, and does not, in any way at
that time interfere with the motion of the weighted pendulum which works the
wheels.

page_text: I EDWARD FISHER BAMBER of 6 St. Swithin's Lane London Civil Engineer 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 is for automatically registering the number of movements of an
oscillating body, or one having a see-saw motion.
The mechanism is contained in a case firmly secured to the oscillating body, and
consists of wheels and levers set in motion by weighted pendulums.
The pendulum (A) is at rest when the case is in the horizontal position, but when
it is tipped, the pendulum moves too, and the ratchet (C) which is attached to the
upper portion (B) and turns upon a pivot moves forward and falls into a tooth of the
ratchet wheel (D). When the case returns to the horizontal position, the pendulum (A)
moves with it, and causes the ratchet (C) to move the wheel (D), the pawl (E)
which may be of any desirable shape being so fixed as to drop at the same time
into another tooth, thus preventing the wheel (D) from running back. The pointer
which is shown in dotted lines in the figure, which represents a full sized back view,
is attached and firmly fixed on the axle (G) on which the wheel (D) revolves,
and as the wheel (D) revolves, the pointer shows on a dial, the number of times
the case has been tipped; the number of marks on the dial being the same as
the number of teeth in the wheel (D). As the wheel (D) completes each revolution
a pin (K) catches a tooth in the wheel (L) and causes it to move one tooth
forward.
The wheel (L) is supplied with a pawl (N), which keeps it motionless until the
pin (K) of the wheel (D) causes it to move as above described. A pointer fixed on
the axle (M) of the wheel L registers on a dial the number of revolutions the first
wheel makes other wheels, pointers and dials may be added if required.
To prevent the weighted pendulum (A) from moving and thus causing the wheel (D)
to revolve except when the case is tipped, stops (S 1) and (S2) are provided, one of
which (S1) catches the head of the pendulum at (H) when the case is in the
horizontal position, and prevents any jerking motion from affecting the pendulum (A),
and the other (S2) catches the lower part (Z) when in the tipping position, and
prevents the pendulum (A) from moving from a jerk or sudden motion.
The stops (S1, S2) are so arranged that they do not interfere with the proper
working of the weighted pendulum (A) when (S1) is on (S 2) is off, and vice versa.

page_text: These stops form the extremities of the levers working on (R) and (R), and are
worked by means of the second weighted pendulum (0) hanging on the spindle (W)
and moving the rocking levers (P, P, P,).
my said
Having now particularly described and ascertained the nature of
Invention, and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The automatic counter substantially as described in the manner and for the
purposes hereinbefore specified, one case of the motion it is designed to register being
that of my Patent hoisting and weighing machine No. 3081 of 1886.
(2) The system of second pendulum, jointed levers and stops substantially as
described which prevent the counter from registering under the influence of jerking
motion.
