Improvements in Weighing Machines.
We, ALEXANDER WOOD, of 10 Stockwell Street, Glasgow, and THOMAS
DAVIES, of 297 Main Street, Bridgeton, Glasgow, Weighing Machine Makers,
do hereby declare the nature of this invention to be as follows:-
This invention relates to weighing machines and is especially adapted for use by
butchers and others for weighing the carcases of animals.
With the present construction of carcase weighing machine it is necessary, to
climb up a ladder in order to read off the weight on the steel-yard which is fitted
up near the ceiling and out of reach.
Our invention has for its object to so construct the weighing machine that the
steel-yard can be fitted near the floor or at other suitable place so as to enable the
weight to be easily and readily ascertained.
In carrying out our invention we suspend the hooks from one end of a lever which
is fulcrumed, at any suitable part in its length, in a hook or shackle secured to the
ceiling or other place. Secured to the other end of the lever is a chain, cord, or
rod, which is attached to the outer end of a lever fitted preferably within a few
feet above or near to the floor level. This lever, which is suitably fulcrumed, is
connected at its inner end, by means of a link or equivalent, to the short arm of the
steel-yard which latter may be of any suitable construction or may be connected
direct to top levers.
A short fever and weight is preferably provided for counterbalancing the weight
of the lever to which the hooks are attached.
The steel-yard and its connected mechanism may be enclosed in a suitable
casing.
With this construction of machine the weight of a carcase can be easily
ascertained without the necessity for mounting a ladder or the like.
The machine, though specially adapted for use by butchers for weighing dead
meat may be used for weighing grain and other materials or substances.

Improvements in Weighing Machines.
We, ALEXANDER WOOD of 10 Stockwell Street, Glasgow, and THOMAS
DAVIES of 297 Main Street, Bridgeton Glasgow Weighing Machine Makers
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 weighing machines and is specially adapted for use by
butchers and others for weighing the carcases of animals.
With the present construction of carcase weigbing machines it is necessary to

page_text: climb up a ladder in order to read off the weight on the steel yard which is fitted
up near the ceiling and out of reach.
Our invention has for its object to so construct the weighing machine that the
steel yard can be fitted near the floor or at other suitable place so as to enable the
weight to be easily and readily ascertained..
In carrying out our invention we suspend the hooks from one end of a lever
which is fulcrumed at any suitable part in its length, in a hook or shackle secured
to the ceiling or other place. Secured to the other end of the lever is a chain,
cord, or rod, which is attached to the outer end of a lever fitted preferably a few
feet above or near to the floor level. This lever, which is suitably fulcrumed, is
connected, at its inner end, by means of a link or equivalent to the short arm of the
steel-yard which latter may be of any suitable construction. If desired the steel-
yard may be connected direct to the top levers.
A short lever and weight is preferably provided for counter-balancing the weight
of the lever to which the hooks are attached.
The steel-yard and its connected mechanism may be enclosed in a suitable
casing.
With this construction of machine the weight of a carcase can be easily
ascertained without the necessity of mounting a ladder or the like.
The machine, though specially adapted for use by butchers for weighing dead
meat, may be used for weighing grain and other materials or substances.
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 front view of the upper levers.
Fig. 2 is a section of the case enclosing the steel-yard, & showing the lower levers.
Fig. 3 is a cross section on the line X-X Fig. 1.
Fig. 4 is a view of a dial indicator.
Fig. 5 is a plan of the end of the lever a.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same parts.
The carcase, bag of grain, or other article to be weighed, is caught on the book i
which is slung from the shackle j at. the right hand end of the long lever a.
This lever a is fulcrumed in the shackle 6 secured to a plate B strongly bolted
to the roof or ceiling A of the shop or warehouse. The left hand end of the
lever is connected by hook-links e to the left hand end of the short lever d
which is fulcrumed in the shackle also secured to the plate B. Suspended on
knife edges from the right hand end of the lever d, by hook links g, are the
counter balance weights h, h. If desired only a single large counter balance weight
may be used.
k is a bar or rod which at its upper end is hooked on a knife edge secured in the
forked left hand end (see Fig. 5) of the lever a. The lower end of the bar k is
hooked to the right hand end of the lever which, as shown, is fulcrumed in the
hook m secured to the floor of the shop or warehouse. The left hand end of the
lever is connected by hooked links n to the left hand end of the steel-yard o.
The steel-yard is fulcrumed in the hook p secured to the top of the enclosing casing
or box g. This box preferably rests on the floor or is supported or secured to the
wall a few feet above it.
If desired the bar k may, as shown at Fig. 4, be connected to and operate a dial
indicator r.
c are knife edge bearings. s is a screw coupling link fitted on the bar k.
When weighing articles with this apparatus it is not necessary to mount a ladder,
as at present, in order to ascertain the weight.
The box or casing q would have a door at the front side in order to gain access
to the steel-yard.
The dial indicator, if used, may be placed on the floor.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
consider novel and desire to claim is :-
The arrangement of levers and their connections substantially as hereinbefore
described and shown on the drawings annexed.
