PROVISIONAL SPECIFICATION.
Improvements in Weighing Machines.
I JOSEPH MICHAEL MCGRATH, of 14, 15, and 16, Cow Cross Street,
London, E.C., Manager, do hereby declare the nature of this invention to be as
follows:-
This invention is particularly applicable to machines for weighing beasts being
sold by auction, where the steelyard is located within an office, and out of sight of
the bidders or purchasers, who have to rely on the accuracy of the weighing clerk,
as he calls out the weights which he reads from the machine.
According to my invention, I arrange on the slides, pointers, which indicate upon
a plate suitably placed in view of the public, the position of the slides on the steel-
yard. The indicator plate is marked with large figures corresponding with the
figures on the steelyard, so that every reading, as the clerk calls out the weights,
may be checked by those standing by, who would not be able to see the figures on
the steelyard itself.
It will be understood that although I have described my invention in connection
with weighing machines for beasts, it is applicable to weighing machines for
other purposes, where a steelyard is used, and where a public view of the readings
of the machine is desirable.
It will be seen that the above described arrangement has all the advantages of
what are known as dial machines, as regards facility of reading, without the disad-
vantages of the latter, viz. their well-known inaccuracy, and their liability to get
out of order, by reason of their more complex construction.

I JOSEPH MICHAEL MCGRATH of 14, 15, and 16, Cow Cross Street,
London, E.C., Manager, 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 particularly applicable to machines for weighing beasts being
sold by auction, where the steelyard is located within an office, and out of sight of
the bidders or purchasers, who have to rely on the accuracy of the weighing clerk,
as he calls out the weights which he reads from the machine.
According to my invention, I arrange on the slides, pointers which indicate,
upon both sides of a plate suitably placed in view of the public, the position of the
slides on the steelyard. The indicator plate is marked with large figures corre-
sponding with the figures on the steelyard, so that every reading, as the clerk calls
out the weights, may be checked by those standing by, who would not be able to
see the figures on the steelyard itself.

page_text: In the accompanying drawing,
Fig. 1 represents in side view a portion of a steelyard weighing machine embodying
my invention.
Fig. 2 is a plan view; and
Fig. 3 is a cross section on the live x x of Fig. 1.
A is the steelyard, and B and C are the usual slides thereon. B is the larger
slide for the hundred weights and stones, and C is the smaller slide for weighing
to lbs. and ozs. D is an indicator plate suitably placed in view of the public, and
marked on both sides with a scale corresponding with, or equivalent to, the scale
shown on the steelyard.
The plate D is shown in the drawing as supported from the pillar and bracket of
the machine by bent arms d d. It is obvious, however, that other means of support
may, if desired, be adopted.
The slides B and C carry fingers and c pointing to the scales of figures on the
plate D. As the slides are moved along the steelyard, the pointers
and c corre-
spondingly travel over the figures of the indicator plate D, and when at rest, show
the weight last recorded on the steelyard.
It will be understood that although I have described my invention in connection
with weighing machines for beasts, it is applicable to weighing machines for other
purposes where a steelyard is used, and where a public view of the readings of the
machine is desirable.
It will be seen that the above described arrangement has all the advantages
of what are known as dial machines, as regards facility of reading, without the
disadvantages of the latter, viz., their well-known inaccuracy, and their liability
to get out of order by reason of their more complex construction.
I may remark that the indicator plate may be used to shew, in English weights,
the readings of the steelyard, which may, for example, be graduated according to
the metric system, or vice versa, and thus readings intelligable to two classes or
nationalities can be simultaneously obtained.
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
In conjunction with a weighing machine having the usual steelyard and slides
thereon, the employment of a suitably placed indicator plate and pointers, such
pointers being connected to the slides on the steelyards, and operated thereby, so
as to give the readings of the weighing machine on the indicator plate, as and for
the purpose set forth.
