I, WILLIAM EDWARD HIPKINS, Managing Director of the Firm of W. and T.
Avery, Limited, of Digbeth, in the City of Birmingham, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
-
This invention consists of improvements relating to steelyard weighing
machines, my objects being to so construct and arrange the steelyard and its
counterpoise weights that the latter can be very readily set to the required balanc-
ing position, and the graduations of the measure upon the face of the steelyard
be read with facility.
I construct a steelyard in accordance with my invention preferably of T section
with the graduations of the required measure or measures upon its open upper face.
On each side of the steelyard and extending throughout its length I arrange a tube
or rod for supporting the sliding counterpoises or jockey weights, the counterpoise
on one of such tubes being sometimes arranged to indicate tare whilst the other
is for the balancing of the actual load to be weighed. When desired the counter-
poises may be made to indicate different standards of weight on the one steelyard.
In another modification I employ but one tube or rod on one side of the steel-
yard only.
Each jockey weight or counterpoise is so arranged that its centre of gravity falls
below the supporting tube and on the side adjacent to the steelyard, in order that it
shall tend always to keep the positioning nib which is fixed on the upper side of the
weight, in position within the particular groove or graduation in which it may be
set until withdrawn by pressure upon a handle effecting a slight rotary movement
of the weight upon the bar. Such handle serves also for sliding the weight or
counterpoise along the bar to the required balancing position.
Small loads are balanced and their weight indicated by a supplementary bar
and movable slide, such supplementary bar being mounted upon the steelyard in
any ordinary manner.
The standard or framing of the machine is of any usual type arranged to suit
the particular service for which it is required. Adjustment of the machine is
provided for by a movable balance carried in the ordinary manner.
My invention is applicable to weigh-bridges, and to platform and other types of
steelyard weighing machines or appliances.

I, WILLIAM EDWARD HIPRINs, Managing Director of the Firm of W. & T.
Avory, Limited, of Digbeth, in 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 relating to steelyard weighing
machines, my objects bung, to so construct and arrange the steelyard and its
counterpoise weights that the latter can be very readily set to the required balanc-
ing position, and the graduations of the measure upon the face of the steelyard to
be read with facility.

In the accompanying sheet of explanatory drawings to be hereinafter referred
Figure 1 is a side elevation, Figure 2 an end elevation, and Figure 3 a plan of a
steelyard constructed and arranged in accordance with my invention.
The same reference letters in the different views indicate the same parts.
I construct a steelyard in accordance with my invention preferably of T section
with the graduations of the required measure or measures upon its upper face.
On each side of the steelyard A and extending throughout its length I arrange
a tube or rod as B and B for supporting the sliding counterpoises or jockey
weights C, C, the counterpoise on one of such tubes being sometimes arranged
to indicate tare whilst the other is for the balancing of the actual load to be
weighed. When desired the counterpoises may be made to indicate. different
standards of weight on the one steelyard.
In another modification I employ but one tube or rod on one side of the steel-
yard only.
Each jockey weight or counterpoise is so arranged that its centre of gravity falls
below the supporting tube and on the side adjacent to the steelyard, in order that it
shall tend always to keep the positioning nib as D and D fixed on the upper
side of each of the weights, in position within the particular groove or grauua-
tion which it may be set until withdrawn by pressure upon a handle as E and E
effecting a slight rotary movement of the weight upon the bar. Such handle
serves also for sliding the weight or counterpoise along the bar to the required
balancing position.
Small loads are balanced and their weight indicated by a supplementary bar F
and movable slide G, such supplementary bar being mounted upon the steelyard
in any ordinary manner.
The standard or framing of the machine (not shown in the figures) is of any
usual type arranged to suit the particular service for which it is required. Adjust-
ment of the machine is provided for by a movable balance carried in the ordinary
manner.
My invention is applicable to weigh-bridges, and to platform and other types of
steelyard weighing machines or appliances.
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 the use of a counterpoise or jockey weight
arranged to slide upon a supporting tube or rod fixed at the 'side of and longi-

page_text: tudinally with the steelyard, the centre of gravity of the counterpoise or jockey
weight being arranged to fall below its supporting tube or rod and on the side
of it adjacent to the steelyard substantially as and for the purposes described.
2. The construction and arrangement of parts forming the improvements
relating to steelyard weighing machines substantially as and for the purposes
described and as illustrated.
Dated this 15th day of July 1898.
