Improvements relating to Steelyards.
Year: 1898

page_text: Improvements relating to Steelyards.
I, CHARLES WILLIAM BRECKNELL, of the Firm of Day and Millward, Limited,
of 118, Suffolk Street, Birmingham, Weighing Machine and Steelyard Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
My invention has for its object the construction and arrangement of a steel-
yard ball or counterpoise weight and its runner or like connection in such a
manner as will prevent the slipping or sliding of such parts down the steelyard
shank when the latter is not in its horizontal or balance position.
To obtain such object in accordance with my invention, I cast with or other-
wise secure to the upper part of the ball or counter-poise weight a malleable
iron or other bracket having a pair of V shaped projections adjacent to the
underside of the steelyard shank. The shank runner or like part by which the
ball is suspended is hooked upon or otherwise connected with the central part
of the said bracket.
When the steelyard shank becomes tilted or inclined below its horizontal or
balance position one of the V shaped projections of the bracket herein before
described engages with the notched lower edge of the shank and thus the ball
becomes locked or secured with the shank. Similarly when the shank is tilted
or inclined above its horizontal or balance position the opposite V shaped pro-
jection of the bracket engages or becomes locked with the notched shank. The
ball with its V shaped bracket on engagement with the shank, when the latter
is tilted or inclined either above or below its horizontal or balance position, is
itself slightly tilted in an opposite direction to the inclination of the shank and
it thus has a tendency to cause the shank to recover its horizontal position.

improvements relating to Steelyards.
I, CHARLES WILLIAM BRECKNELL, of the Firm of Day and Millward, Limited,
of 118, Suffolk Street, Birmingham, Weighing Machine and Steelyard Manu-
facturers, do hereby declare the nature of this invention and in what manner
[Price Sd.]

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
-
My invention has for its object the construction and arrangement of a steel-
yard ball or counterpoise weight and its runner or like connection in such a
manner as will prevent the slipping or sliding of such parts down the steelyard
shank when the latter is not in its horizontal or balance position.
To obtain such object in accordance with my invention, I cast with or other-
wise secure to the upper part of the ball or counterpoise weight a malleable
iron or other bracket having a pair of V shaped projections adjacent to the
underside of the steelyard shank. The shank runner or like part by which the
ball is suspended is hooked upon or otherwise connected with the central part
of the said bracket.
When the steelyard shank becomes tilted or inclined below its horizontal or
balance position one of the V shaped projections of the bracket hereinbefore
described engages with the notched lower edge of the shank and thus the ball
becomes locked or secured with the shank. Similarly when the shank is tilted
or inclined above its horizontal or balance position the opposite ▼ shaped pro-
jection of the bracket engages or becomes locked with the notched shank. The
ball with its V shaped bracket on engagement with the shank, when the latter
is tilted or inclined either above or below its horizontal or balance position, is
itself slightly tilted in an opposite direction to the inclination of the shank and
it thus has a tendency to cause the shank to recover its horizontal position.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to.-
Figure 1 is a side elevation representing a steelyard with my improved
counterpoise, and Figure 2 is an end elevation of the same on the line a b
Figure 1.
Figure 3 is a side elevation representing a portion of the steelyard shank
depressed or overbalanced by the counterpoise, and Figure 4 is a similar view
showing the steelyard shank and its counterpoise in an elevated position or
over-balanced by the load to be weighed.
The same reference letters in the different views indicate the same parts.
The malleable cast iron or other bracket A, having a pair of V shaped pro-
jections adjacent to the underside of the steelyard shank B, is cast with or other-
wise secured to the upper part of the ball or counter-poise weight C which is
suspended from the shank by the runner D.
When the steelyard shank becomes tilted or inclined below its horizontal or
balance position, as indicated at Figure 3, one of the V shaped projections of
the bracket A engages with the notched lower edge of the shank and thus pre-
vents slipping or sliding of the weight C. Similarly when the shank is tilted
or inclined above its horizontal or balance position, as indicated at Figure 4, the
opposite V shaped projection of the bracket engages or becomes locked with the
notched shank.
As will be seen at Figures 3 and 4 the ball C with its V shaped bracket A
becomes tilted in an opposite direction to the inclination of the shank, and by
its effort in such position to move back in the direction indicated by the respec-
tive arrows in the said figures, it tends to cause the shank to recover its hori-
zontal position on removal of the overbalancing force.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I wish it to be
understood that I am aware of the Specification of Letters Patent No. 8334 of
1891 granted to H. J. Avery and G. W. Davis and that I claim nothing described
and claimed in the Specification of said Letters Patent, but, I declare that what
I claim is
In steelyards, the combination with the weight or counterpoise as C and the

page_text: runner or like connection D, of a bracket A which on the inclination of the
shank B above or below its horizontal position becomes tilted in an opposite
direction and engages with the lower edge of the said shank, substantially as
described and as illustrated.
