PROVISIONAL SPECIFICATION.
Improvements in Counter and other Weighing Machines.
I, WILLIAM BEILBY AVERY, Managing Director of the Firm of W. & T. Avery
Limited, Weighing Machine Manufacturers, of Digbeth, in the City of Birmingham,
do hereby declare the nature of this invention to be as follows :-
This invention relates to improvements in counter and other weighing machines
having an independent pan or other receptacle, my object being to provide a better
support or underframe for such pan or receptacle than exists with the machines at
present in ordinary use, and to so arrange the working parts or weighing mechanism
as to permit of convenient adjustment.
In carrying my invention into effect in the construction of a weighing machine
or balance for use upon a counter or table, I form the beam in the usual manner
with suitable knife edges supported by bearings mounted upon the framing or
standards of the machine. One end of the beam is provided with an ordinary
fixed tray for the reception of the standard weights and is connected, preferably
by a single stay, with the guide lever mounted in the base of the machine. Upon
the opposite end of the beam I mount a cross-piece for supporting the pan or
other receptacle, and connect the same to suitably arranged guide levers in the
base of the machine by means of double stays attached at opposite ends of the
cross-piece. Stop pieces formed upon or attached to each of the stays limit
the movement of the beam and relieve the same from the stress of any unbalanced
weight on either side.
By my arrangement of double stays beneath the cross-piece as herein before
described, I provide a rigid support for the pan or other receptacle enabling a
load to be placed upon one side or in any position upon
the pan
producing a lateral or side stress on the beam or rendering the pan liable to
overturn.
without
the
I preferably fix the framing or standards for supporting the beam upon
upper side, and the guide lever brackets or pivot heads upon the lower side of a
base plate which I bolt or otherwise secure to the base in such a manner that it
may be readily disconnected for adjustment or other purposes. Thus the whole
of the working parts of the machine are mounted upon the one detachable
base plate, and are so arranged thereon as to permit of ready and convenient
adjustment.
I adapt my invention to weighing machines of varying design, making such
modifications as may be necessary to suit the requirements of particular services.
Dated this 21st day of January 1894.

Improvements in Counter and other weighing machines.
1, WILLIAM BEILBY AVERY, Managing Director of the Firm of W. & T. Avery
Limited, Weighing Machine Manufacturers, of Digbeth, in the City of Birmingham,
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 counter and other weighing, machines
having an independent pan or other receptacle, my object being to provide a better
support or under frame for such pan or receptacle than exists with the machines at
present in ordinary use, and to so arrange the working parts or weighing mechanism
as to permit of convenient adjustment.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to,
-
"Figure 1 is a plan, and Figure 2 a side elevation representing a counter
weighing machine constructed in accordance with my invention.
Figure 3 is an end elevation of the machine, showing the support or under frame
for the pan.
Figure 4 is an end elevation illustrating a modified arrangement of the pan
under frame.
The same reference letters in the different views indicate the same parts.
In carrying my invention into effect in the construction of a weighing machine
or balance for use upon a counter or table, such as illustrated in the accompanying
drawings, I form the beam A in the usual manner with suitable knife edges
supported by bearings mounted upon the framing or standards B B₁ of the
machine. One end of the beam A is provided with an ordinary fixed tray, such
as C, for the reception of the standard weights, and is connected, preferably by
a single leg D, with the guide lever or stay D', mounted in the base of the
machine.
Upon the opposite end of the beam I 'mount a cross piece E, (Figure 3) having
knife edges för supporting the pan F or other receptacle carried on the under-
'frame G, and connect the same to suitably arranged guide levers or stays such
as EE2, in the base of the machine by means of the legs E³ E. Stop pieces e
formed upon or attached to each of the stays limit the movement of the beam, and
relieve the same from the stress of any unbalanced weight on either side.
Instead of transmitting the weight of the pan F and its contents to the under
frame by means of the lugs or suspension pieces H H₁ as at Figure 3, 1 sometimes
form seatings for the knife edges of the cross piece E within the legs E³ and E* as
shown at Figure 4.
By my arrangements of under frame with double stays beneath the cross piece
as hereinbefore described, I provide a rigid support for the pau or other receptacle
enabling a load to be placed upon one side or in any position on the pan without
producing a lateral or side stress on the beam or rendering the pan liable to
overturn.
I preferably fix the guide lever brackets or pivot heads upon the lower side of a
base plate B formed with the standards B B₁ and which I bolt or otherwise secure
to the base of the machine in such a manner that it may be readily disconnected
for adjustment or other purposes. Thus the whole of the working parts of the
machine are mounted upon the one detachable base plate and framing and are so
arranged thereon as to permit of ready and convenient adjustment.
I adapt my invention to weighing machines of varying design making such
modifications as may be necessary to suit the requirements of particular services.

page_text: 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
1. The improved method of supporting the independent pan or other receptacle
of a weighing machine substantially as herein described.
2. In counter and other weighing machines the use of an under-frame having
legs and stays substantially as and for the purposes hereinbefore described and as
illustrated in the accompanying drawings.
3. The improved general construction and arrangement of a counter or other
weighing machine substantially as and for the purposes hereinbefore described and
as illustrated in the accompanying drawings.
Dated this 21st day of October 1895.
