PROVISIONAL SPECIFICATION.
Improvements in Steelyard Weighing Machines.
I, WILLIAM EDWARD HIPKINS, Managing Director of W. & T. Avery Limited,
of Soho Foundry, near the City of Birmingham, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
This invention consists of improvements in steelyard weighing machines of
the weighbridge, platform, and other types, my object being to provide on such
machines simple and convenient means for printing or recording the weights
indicated in more than one system or standard.
In the application of my invention to a steelyard weighing machine which is
required for indicating weights according to the English system or standard and
the metric system or standard, I construct the steelyard in any ordinary manner
but provide it with a double row of notches running parallel, each row being
graduated according to one or the other of the two standards named. On the
under side of the steelyard two sets of printing figures are arranged, respectively
corresponding with the two standards of weight. The larger or main sliding
poise of suitable construction is mounted on the steelyard, and one or more of
the usual smaller poises are arranged on the said larger or main poise for ascer-
taining small increments of weight, the ends of such smaller poises being
respectively graduated according to the two standards. The undersides of the
smaller poises, like the underside of the steelyard, are fitted with hardened
steel or other printing figures.
At one end of the main poise I pivot a positioning nib having a pair of edges
arranged to engage with the steelyard notches. By adjusting the nib in one
direction one of the said pair of edges is brought into position for engaging with
the row of notches graduated according to the English standard, whilst a move-
ment in the opposite direction will throw such edge out of position and bring
the opposite edge into position for engaging with the row of notches graduated
according to the metric standard.
The underside of the main poise is provided with a pair of ticket slots, one for
each standard of weight, disposed at such a distance apart that the set of figures
at one end of the smaller poises will not under any circumstances reach the
ticket slot at the opposite end of the main poise, and I thus avoid double print-
ing or printing in the two standards on the one ticket. In the case of the main
poise double printing is prevented by making the figures on the underside of the
steelyard in different planes, the rows of figures representing the one standard
being placed lower than the rows representing the other standard. The figures
on the smaller poises are of course arranged on the same plane or level as that of
the figures on the steelyard with which they correspond: the two ticket slots
are also disposed at the respective levels of the two sets of figures.
The imprint or record on the tickets is taken in the usual way by the operation
of the ordinary printing handle one of which is arranged beneath each slot.
The slots can be made adjustable if desired, thus enabling imprints to be taken
of the gross. tare. and nett weights, on the one ticket.

page_text: Whilst preferably employing double slots upon the main poise as hereinbefore
described, I sometimes arrange such slots in the fixed head of the pillar such as
is found in the smaller type of platform machines, and the raised figures can
also be arranged in different positions on the steelyard and the moving poises.
The printing figures can be also arranged upon the peripheries of circular
discs actuated and positioned by the moving poises by means of toothed racks
and pinions.
By my improvements a permanent and accurate record in any two standards
can be readily obtained at the time of weighing without the inconveniences
attendant upon the conversion of the readings in one standard into readings in
the other standard

10s in Steelyaru weigning Machines.
I, WILLIAM EDWARD HIPKINS, Managing Director of W. & T. Avery Limited,
of Soho Foundry, near the City of Birmingham, Manufacturers, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention consists of improvements in steelyard weighing machines of
the weighbridge, platform, and other types, my object being to provide on-such
machines simple and convenient means for printing or recording the weights
indicated in more than one system or standard.
On the accompanying sheet of explanatory drawings to be hereinafter referred
to,―
Figure 1 is a side elevation, and Figure 2 a sectional end elevation, on the
line a Figure 1, representing a portion of a steelyard with poises having my
invention applied thereto.
The same reference letters in the two views indicate the same parts.-- .
In the application of my invention to a steelyard weighing machine which is
required for indicating weights according to the English system or standard and
the metric system or standard, I provide the steelyard as A with a double row of
notches a a² running parallel, each row being graduated according to one or the
other of the two standards named. On the underside of the steelyard two sets
of printing figures are arranged, respectively corresponding with the two standards
of weight; the figures are formed with a plate A' which is secured to the under-
side of the steelyard A.
The larger or main sliding poise B of suitable construction is mounted on the
steelyard, and two smaller poises C and D are arranged on the said larger or
main poise B for ascertaining small increments of weight, the ends of such
smaller, poises, being respectively graduated according to the two standards.
The undersides of the smaller poises like the underside of the steelyard, are pro-
vided with hardened steel or other printing figures.
F
At one end of the main poise I pivot a positioning nib having a pair of edges
arranged to engage with the steelyard notches, or a
a ring E mounted on a screw F which enters the projecting portion B' of the
single nib as E formed with

page_text: poise B. The said ring has a milled edge to permit of its being so turned or
rotated as to cause the nib E to engage with either the one or the other of the
rows of notches a' a. Thus by adjusting the nib in one direction it is brought
into position for engaging with the row of notches graduated according to the
English standard, whilst a movement in the opposite direction will throw the
nib out of such position and bring it into position for engaging with the other
row of notches graduated according to the metric standard.
The underside of the main poise is provided with a pair of ticket slots as G
and H, one for each standard of weight, disposed at such a distance apart that
the set of figures at one end of the smaller poises (C and D) will not reach the
ticket slot at the opposite end of the main poise, and I thus avoid double printing
or printing in the two standards on the one ticket. In case of the main poise
double printing is prevented by making the figures on the underside of the
steelyard in different planes, the rows of figures representing the one standard
being placed lower than the rows representing the other standard. The figures
on the smaller poises are of course arranged on the same plane or level as that
of the figures on the steelyard with which they correspond; the two ticket slots
are also disposed at the respective levels of the two sets of figures.
On the drawing the figures for printing in the one standard are represented
by the letter e and the figures for the other standard by the letter m.
The imprint or record on the tickets is taken in the usual way by the operation
of the ordinary printing handle, as G¹ and H' one of which is arranged beneath
each slot. The slots can be made adjustable in the ordinary manner if desired.
thus enabling imprints to be taken of the gross, and tare weights, on the one
ticket.
In platform machines of a smaller type I arrange the pair of ticket slots in
the fixed head of the pillar used in such machines, and dispose the printing
figures around the peripheries of circular discs actuated, on the movement of
the poises, by means of toothed racks connected with the poises and gearing
with pinions formed with or attached to the printing discs.
Instead of employing raised printing figures as herein before described I some-
times provide sunk or depressed figures for embossing the tickets.
By my improvements a permanent and accurate record in any two standards
can be readily obtained at the time of weighing without the inconveniences
attendant upon the conversion of the readings in one standard into readings in
the other standard.
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 claim is:
1. In steelyard weighing machines, means for printing or recording the
weighings in more than one system or standard, comprised in part of printing
figures arranged in different planes, substantially as described.
2. The improved steelyard, poises, and attachments, for a weighing machine
of the weighbridge, platform, and other types so constructed and arranged that a
permanent and accurate weight record in any two standards can be readily
obtained from the machine at the time of weighing, substantially as described
and as illustrated.
