PROVISIONAL SPECIFICATION.
Improved Apparatus for Recording the Weighings of Weigh Tables,.
Beam Scales, and the like.
JOHN PETERSON Jr., Collector cf Harbour Dues, Granton Harbour, residing
at Pennywell, Granton, Edinburgh, do hereby declare the nature of this invention.
to be as follows:-
This meter has been designed to register automatically the number of weighings
made by sworn weighers of grain, or others, in the docks, harbours, ports, or other
places, in the United Kingdom.
The apparatus consists of an arrangement of clockwork in its front compartment,
which is actuated by a three toothed ratchet wheel in its back compartment.
The ratchet wheel is actuated by a lever which projects through the circum--
ference of this back compartment.
The lever has a pair of hinged jaws which fold backwards, and partly encircle
the bow of the grain weighing barrel: when not in use the jaws are folded forwards.
and padlocked to the machine.
The apparatus is attached to the axle of the weighing barrel by means of a
screwed pin fixed to its back, which pin is screwed tightly into the axle of the
weighing barrel.
When the weighing barrel is tipped up to empty its contents the suspending bow
remains plumb, but the axle with the apparatus attached travels through about a
third of its circumference thereby enabling a pawl on the lever to catch one of
the three ratchet teeth; on allowing the barrel to return to its vertical position
the lever moves the ratchet wheel through one-third of its circumference and by
doing so registers one weighing on the first of the dials.
There are three dials on the face of this apparatus which respectively
indicate No. 1 up to 10 weighings, No. 2 up to 100 weighings and No. 3 up to
1000 weighings.

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 relates to the means of recording the successive weighings of
grain by sworn weighers.
Fig. 1 of the accompanying drawings is a front view showing the dial of the
apparatus.
Fig. 2. is a back view.

page_text: Fig. 4. is a view of the inner arrangement as seen from the back with the outer
back covering removed.
Fig. 5 is a side view showing the inner arrangement of the wheelwork and
lever and attachment to barrel.
Fig. 6 is a drawing of the jaws of the lever of the apparatus.
Figs. 7 & 8 are drawings of the barrel with the apparatus attached.
Fig. 9 is a drawing of the tilted barrel with the apparatus attached, according
to my invention.
A the lever is hinged to enable it to catch the bow of the barrel when ready for
work, or when not at work so that it may be folded back and padlocked by the
weigher to prevent tampering.
B is a spring catch for keeping jaws of lever in working position.
C. is the three-toothed ratchet wheel moved by the lever A.
D. D. are pawls with springs, one of which is attached to the lever A and the
other to the frame of the apparatus.
E is a screwed pin riveted to the back of the apparatus for attaching it to the
axle of the barrel and firmly fixing it by means of the jam nut F.
G is the bow of the weighing barrel.
H is the weighing barrel.
METHOD OF USING THE APPARATUS.
The weigher receives the grain into the barrel H as shown in Figures 7 & 8 and
after weighing the grain empties it as shown in Fig. 9 by tilting the barrel. The
apparatus for recording the number of times the barrel is emptied is screwed into
the axle of the barrel by means of the screw E and firmly fixed in position after
adjustment by the jam nut F. Accordingly each time the barrel is tilted in being
emptied the ratchet wheel C.(Fig. 4 & 5) is caused to travel through the same
angle as that of the axis of the barrel in tilting, this has the effect of making the
pawl D on the lever (Fig. 4 & 5) to catch the succeeding tooth of the ratchet
wheel C, so that when the now empty barrel returns to its upright position the
ratchet wheel is driven round by the lever the distance necessary to register oue
weighing on the dial. To prevent a backward movement of the ratchet wheel the
pawl D on the frame of the apparatus drops into the following tooth immediately
after each weighing is recorded, consequently by this means it is impossible for an
erroneous record of weighings to be made. In this apparatus the dial-work is
capable of registering from I up to 1000 separate weighings.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed; I declare that what I
claim is :-
Apparatus for recording automatically the weighings of weigh tables, beam
scales, and the like.
