PROVISIONAL SPECIFICATION.
An Appliance for the Automatic Registration of the Number of
Weighings Taking Place on a Machine or of Distinct Pressures
or Tensions Exerted.
ALEXANDER WOOD, 10 Stockwell Street, Glasgow, Weighing Machine Maker, do
hereby declare the nature of this invention to be as follows:-
The object of my invention is the automatic registration of the number of weighings
taking place in any given period of time previously fixed or arranged, upon any
kind of weighing machine, or distinct pressures or tensions such as a wheel, barrel,
or person passing over respectively, a part of a rail, plank in a floor, tread of a
step, or other loose part connected with my appliance. This I accomplish by means
of a lever or spring or other appliance connected with the suspending hook of a
beam or lever or any other kind of suspended machine and in platform or other
machines such as those in use at railway stations, warehouses, public works, and
other places for weighing parcels, boxes, bales, barrels, and any other kind of goods,
also the heavier class for weighing hutches, carts, lorries, railway and other waggons,
and other bulky or heavy articles. The connection is made from the link or shackle
carrying the index steelyard and in all cases it is independent of the weighing
parts of the machine and therefore cannot interfere with the accuracy of the
weighings indicated. With the deadweight of the suspended part of the weighing
apparatus as it stands without any weight on the platform, goods, or weight scale,
the lever will be at rest, kept in this position by a balance weight attached or held in
position by a spring, or other device, a second or more levers can be added (where
greater power is required) in any other way such as a spring connected directly to
the suspended hook or eye. To this balance lever or spring must be added sufficient
power to balance at least two thirds, or three fourths or other proportion of total
weight, and sufficiently near the total limit of weighings to prevent a registration
taking place with the movement of the scales or the running over (as in case of
weighing coal), or on placing an empty hutch upon the scale. The movement of
this lever connected with a counter through a certain given are gives the required
registration. The same machine may be used for enumerating any number of articles,
persons, or animals, passing over a given place, independent of a weighing machine,
by connecting it with a loose board, rail, step, or any other means of communicating
pressure or tension, thus causing the movement of the lever necessary to move the
counter one indication.

COMPLETE SPECIFICATION.
An Appliance for the Automatic Registration of the Number of
Weighings Taking Place on a Machine or of Distinct Pressures
or Tensions Exerted.
1. ALEXANDER WOOD, 10 Stockwell Street, Glasgow, Weighing Machine Maker,
do bereby 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 my invention is the automatic registration of the number of weighings
taking place in any given period of time previously fixed or arranged upon any kind
of weighing machine, or distinct pressures or tensions such as a wheel, barrel, or

page_text: person passing over, respectively, a part of a rail, plank in a floor, tread of a step, or
other loose part, connected with my appliance. This accomplish by means of a lever
or spring or other appliance connected with the suspending hook of a beam or lever
or any other kind of suspended machine and in platform or other machines such as
those in use at railway stations, warehouses, public works, and other places for
weighing parcels, boxes, bales, barrels, and any other kind of goods, also the heavier
class for weighing hutches, carts, lorries, railway and other waggons, and other bulky
or heavy articles. The connection is made from the link or shackle carrying the
index steelyard and in all cases it is independent of the weighing parts of the machine
and therefore cannot interfere with the accuracy of the weighings indicated.
With
the dead weight of the suspended part of the weighing apparatus as it stands without
any weight on the platform, goods, or weight scale, the lever will be at rest, kept in
this position by a balance weight attached or held in position by a spring, or other
device or a second or more levers can be added (where greater power is required) or
the lever may be kept at rest in any other way such as a spring connected directly to
the suspended hook or eye. To this balance fever or spring must be added sufficient
power to balance at least two thirds or three fourths, or other proportion of total
weight, and sufficiently near the total limit of weighings to prevent a registration
taking place with the movement of the scales, or the running over (as in case of
weighing coal), or on placing an empty hutch upon the scale. The movement of this
lever through
a certain given are, when connected with a counting machine, gives
the required registrations.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings whereon:-
Fig. 1. is a side elevation of the appliance as fitted on a grain weighing machine
with enclosing casing partly broken away.
Fig. 2 is a plan.
Fig. 3 an end elevation.
Fig. 4a detail view, and
Fig. 5 shows a grain weighing machine with my registering appliance fitted
thereto.
Referring to the drawings whereon the same reference letters wherever repeated
indicate similar or like parts-
も
is the eye or hook from which the beam is suspended, as shown in Fig. 5. The
eye, a, may be made in one piece with or attached to a casing or to a link. Into
the casing is or may be fitted the suspending rode which is supported at its upper
end on knife edges c a lever d. The rod c is held in place in the casing 6 by
means of a nut e screwed on its lower end. Between the nut e and the cover ¹
of the casing a rubber or other soft washer, may be inserted to serve as a cushion
or buffer.
The lever d is fulcrumed at g, g', in standards h.
The end of the
leverd is connected by links to the short arm of a second lever j. The lever which
is fulcrumed at in standards k may have a movable weight, 4, on it. By traversing
the weight back or forward, more or less power is given to the lever as may be
desired. The weight may be clamped in position on the lever by means of a
screw or other suitable device. The lever is or may be connected by a jointed
lever m to the counting machine n. The counting machine may be of any suitable
kind. To prevent the lever j rising up too high a catch o is provided. The catch o
is shown more particularly at Fig. 4.
As shown at Fig. 5. the registering appliance is preferably enclosed in a casing or
box P.
If desired the casing
may be dispensed with and the rod c he itself provided
with a suspending hook or eye.
A spring may be used instead of the weight 1.
The modus operandi of the apparatus is as follows:-
Directly pressure or tension is exerted on the eye a, by the goods, animal, or person,
being weiglied, the rod c is drawn down and also pulls down the lever d, turning on
the fulcrum gg. The downward movement of the lever d draws down the links i

page_text: and through them the short arm of the lever j, turning on the fulcrum 7, at the
same time elevating the long arm of the lever. The elevation of the long arm moves
the jointed lever m so as to turn the counter one point. Immediately the weighing
operation is over the counter-balance weight brings back the apparatus to its normal
position ready for the registration of another weighing.
Although I have only shown the appliance, by way of illustration, as fitted to a
grain weighing machine it is equally applicable for any other class of weighing or
like machines.
The appliance as will be readily understood, from the description already given is
also applicable for use as an enumerator or register of the number of people, articles,
or animals passing over a given place independently of a weighing machine. The
appliance would in this case be connected to a loose board, rail, step or any other
suitable means of communicating pressure or tension so as to cause the lever j to
operate the lever m and through it the counter n.
My appliance is especially useful for grain weighers, colliery proprietors, and others
for determining the number of weighings, that have taken place over the machine or
beam as it obviates the necessity of tallying with chalk or other marks which are
constantly the cause of mistakes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
An automatic registering appliance constructed and operating substantially as
herein before set forth.
