IMPROVEMENTS IN SCALES FOR WEIGHING
Year: 1884

page_text: PROVISIONAL SPECIFICATION,
I JAMES GILLMAN of Guildford Street, Leeds in the County of York, Scale
Manufacturer do hereby declare the nature of said invention for "IMPROVEMENTS
IN SCALES FOR WEIGHING" to be as follows:-
".
The object of my Invention is so to construct scales for weighing that for the
same capacity they shall tako up less room than scales now in use; also to bring
the fulcrum of the beam very much lower or nearer the counter than is at present
usual without destroying the uniformity in the appearance, and the accuracy of the
scale; and further, scales constructed according to my improvements are more than
usually sensitive and quicker in action.
According to my Invention I make the beam of the scale curved, so that the
centre of the beam is much lower than the two sides where the scale pans are
attached or supported. I dispose of the counterpoise balance or weights by
attaching a cup to the underside of the weigh plates to hold the lead necessary
for balancing. A corresponding hole is made in the slab base or foundation plate
in which the cap drops. I thereby dispose of the counterpoise balance which is
often unsightly, and this improvement also enables the flat weight scales pan to
rest nearly level with the slab base, thus enabling the user to weigh, without
having to lift the weights as high as is ordinarily required.

I JAMES GILLMAN of Guildford Street Leeds in the County of York, Scale
Manufacturer do hereby declare the nature of said Invention for "IMPROVEMENTS
IN SCALES FOR WEIGHING" and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
The object of my invention is so to construct scales for weighing that for the
same capacity they shall take up less room than scales now in use; also to bring
the fulcrum of the beam very much lower or nearer the counter than is at present
usual, without destroying the uniformity in the appearance, and further scales
constructed according to my improvements are more than usually sensitive and
quicker in action.
And in order that my invention may be more completely understood reference is
given to the accompanying drawings and to the letters and marks thereon..
DESCRIPTION OF DRAWINGS.
Fig 1 is an elevation of stand scales. Fig 2 a detail section of the same, and
Fig an elevation of suspended scale.
According to my invention I make the beam a in each case curved as shown at b
so that the centre portion of beam a is much lower than the two sides d and e
where the scale pans are attached or supported. I dispose of the couterpoise balance
which is usually attached to the beam at f, and attach a cup g to the underside of
the weight plate h, to hold the lead necessary for balancing. A corresponding
hole i as shewn at Fig 2 is made in the slab, base or foundation platej into which
the cup g drops when the weigh plate descends. I thereby dispose of counterpoise
balance which is often unsightly, and this improvement enables the flat weight
plate or pan h to rest nearly level with the slab j, thus enabling the usor to weigh
without having to lift the weights as high as is ordinarily required.
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
1st The employment of scale beams curved as shown at b for the purpose of
bringing the fulcrum of the beam lower or nearer the counter, and for rendering
the same more sensitive and quicker in action, substantially as herein set forth.
2nd The application of the cup g at the under side of the weigh plate h for
holding the lead necessary for balancing the scales, also the hole i in the slab j for
receiving the same substantially as herein set forth.
