Improvements in Earthenware, China, Glass, and other Vessels to
be used as Measures.
I, JOHN TAMS of the Crown Pottery, Longton, in the County of Stafford,
Earthenware Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention consists in forming a suitable elevation or projection either on or
over the handle or in any other convenient position, such as on the rim or spout,
of any earthenware china glass or other vessel that is to be used as a measure.
then recess and grind or cut down, or otherwise reduce such elevation or projection
so as to regulate the containing capacity of the vessel to the exact measure required.
This effect without in any way damaging the vessel which as regards vessels
made of earthenware or china may be either in the clay, biscuit or
glost state.
The accompanying drawings shew side and back elevations of a drinking measure
made according to my invention.
Similar letters indicate corresponding parts in both figures.
a is the elevation or projection which is here shewn at the back of the measure
immediately above the handle. the recess in such elevation or projection which
recess may be of any convenient shape. the lip at the top of such elevation or
projection which is formed by grinding cutting or otherwise reducing the same in
the manner hereinbefore described.
My invention is applicable to any kind of vessel that is to be used as a measure.
I would here observe that the primary feature of my invention is forming an
elevation or projection on the vessel in any convenient position and subsequently
reducing such elevation or projection so that it correctly indicates the containing
capacity of the vessel. Preferably I form a suitable recess in such elevation or
projection so as to more readily perceive when the vessel contains the proper
quantity but such recess is a secondary feature, and, if desired may be dispensed
with. I would also add that I make no claim to the operations of grinding and
cutting hereinbefore referred to, as being novel in themselves, but only as a means
of reducing the elevation or projection to the required dimensions.
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 1
claim is
1. In an earthenware, china, glass or other vessel that is to be used as a measure
forming a suitable elevation or projection either on or over the handle, or in any
other convenient position, such as on the rim or spout, all substantially as herein-
before described and shewn,
2. Making a recess of any convenient shape in such elevation or projection all
substantially as hereinbefore described and shewn.
3. Grinding cutting down or otherwise reducing the top of such elevation or
projection, all substantially as herein before described and shewn.
4. The improved means for regulating the containing capacity of an earthenware,
china, glass or other vessel that is to be used as a measure all substantially as
hereinbefore described and shewn.
