PROVISIONAL SPECIFICATION.
Improvements in Steel-yards and like Weighing Appliances.
We, GEORGE HUGHES, of 140, Alma Street, Aston, in the County of
Warwick, Scale Maker, and ARTHUR GEORGE BIRCH, of 146, Emily Street,
Highgate, in the City of Birmingham, Scale Maker, do hereby declare the nature
of this invention to be as follows:--
This invention relates to improvements in steel-yards and like weighing
appliances, our object being to prevent excessive movement of the steel-yard or
lever on the suspension of the load to be weighed, without impairing the simplicity
and efficiency of the appliance by the employment of inconvenient fittings or
attachments.
In carrying our invention into effect, we construct the steel-yard of the ordinary
form, having a hook and shackle with knife edge bearings for suspending the
appliance and attached load from a beam or other convenient support, and a similar
book and shackle for the suspension from the steel-yard of the load to be weighed.
The long arm of the lever is graduated to indicate the weight suspended from the
short arm, which is balanced by the runner with attached poise when placed at
various positions along the steel yard. Upon each side of the steel-yard head we
form a lug or projection, to form a stop piece for a similar lug or projection ou
each of the booked suspension shackles herein before described. We so arrange the
adjacent or bearing edges of the lugs or projections as to limit the movement of the
ends of the steel-yard within a small angle, thus providing sufficient play or
movement to enable the load to be accurately weighed or balanced, but effectually
preventing any excessive movement, and so avoiding the inconvenience in weighing,
and liability to derangement of the apparatus common to steel-yards having no
such check or limit to their movement.
We do not limit the application of our invention to any one type or pattern of
steel-yard or like weighing appliance, but adapt the same with such modifications
as may be required to suit modified patterns for various trades, or for any particular
class of goods, or materials to be weighed.

Improvements in Steel-yards and like Weighing Appliances.
We, GEORGE HUGHES, of 140 Alma Street, Aston, in the County of
Warwick, Scale Maker, and ARTHUR GEORGE BIRCH, of 146, Emily Street,
Highgate, in the City of Birmingham, Scale Maker, 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 improvements in steelyards and like weighing
appliances, our object being to prevent excessive movement of the steelyard or

page_text: lever on the suspension of the load to be weighed, without impairing the simplicity
and efficiency of the appliance by the employment of inconvenient fittings or
attachments.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to :-
Figure is an elevation of a steelyard constructed in accordance with our
invention, with the shackles arranged for weighing a light load.
Figure 2 is an elevation of the steelyard showing the shackles arranged for
weighing a heavier load.
Figure 3 is a side elevation, and Figure 4 an end elevation showing a stop piece
secured to the steelyard head.
Figure 5 is a side elevation and Figure 6 an end elevation illustrating one end of
a suspension shackle having a projecting stop piece.
The same reference letters in the different views indicate the same parts.
In carrying our invention into effect, we construct the steelyard of the ordinary
form, having a hook and shackle such as A with knife edge bearings for suspending
the appliance and attached load from a beam or other convenient support when
weighing a light load, and a similar hook and shackle B for weighing a heavier
load. The load to be weighed is suspended by means of the shackle C. The long
arm of the lever is graduated to indicate the weight or load suspended from the
short arm, such load being balanced by the runner with attached poise D when
placed at the necessary position along the steelyard.
Upon opposite sides of the steelyard head we form lugs or projections such
as E E' to form stop pieces for lugs or projections as F Figures 5 and 6 on the
lower ends of the hooked suspension shackles A and B. We so arrange the
adjacent or bearing edges of the lugs or projections as to limit the movement of
the ends of the steelyard within a small angle, thus providing sufficient play or
movement to enable the load to be accurately weighed or balanced, but effectually
preventing any excessive movement, and avoiding the inconvenience in weighing,
and liability to derangement of the apparatus common to steel-yards having no
such check or limit to their movement.
We do not limit the application of cur invention to any one type or pattern of
steel-yard or like weighing appliance, but adapt the same with such modifications
as may be required to suit the differing patterns for various trades, or for any
particular class of goods, or materials to be weighed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is.
1. The improved method of preventing excessive movement of the lever of
a steel-yard or like weighing appliance substantially as described.
2. In steel-yard and like weighing appliances the combination of a projecting
stop piece such as E upon the lever with a lug or projection F from the suspension
shackle substantially as and for the purposes hereinbefore described and as
illustrated in the accompanying drawings.
