PROVISIONAL SPECIFICATION.
Improvements in Sugar Crushers.
I, THOMAS WILLIAM NEWEY, of Allison Street, Birmingham, Warwickshire,
Manufacturer, do hereby declare the nature of this invention to be as follows :-
This invention has reference to those sugar crushers which are used in glasses of
spirits and other hot drinks. Heretofore an instrument with a flat or rounded end
has commonly been used for this purpose but it is well known that when in use
unless great care is exercised the crusher is liable to slip off the lump of sugar and
cause the glass and contents to upset.
My improved sugar crusher herein described is so designed as to afford when in
use a good hold upon the sugar and thus prevent slipping and by it less force is
required than heretofore to crush the sugar.
My said improved sugar crusher consists of a stem of suitable length having an
enlarged lower end which is concave or hollowed underneath. This concavity may
either be smooth or it may be roughened by sharp ribs or other projections or by
recesses. Projecting from the centre of the said concave part there is, or may be,
a short sharp spike which when made in metal may form one end of the shank part
to which the concave part is fixed. The concave shape of the crusher prevents it
from slipping off the lump of sugar and by employing the said internal projections
the crushing is facilitated.
Dated this 8th day of December 1890.

Improvements in Sugar Crushers.
1,, THOMAS WILLIAM NEWEY, of Allison Street, Birmingham, Warwickshire,
Manufacturer, 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 has reference to those sugar crushers which are used in glasses of
spirits and other hot drinks. Heretofore an instrument with a flat or rounded end
has commonly been used for this purpose but it is well known that when in use
unless great care is exercised the crusher is liable to slip off the lump of sugar and
cause the glass and contents to upset.
My improved sugar crusher herein described is so designed as to afford when in
use a good hold upon the sugar and thus prevent slipping and by it less force is
required than heretofore to crush the sugar.
My said improved sugar crusher consists of a stem of suitable length having an
enlarged lower end which is concave or hollowed underneath. This concavity may
either be smooth or it may be roughened by sharp ribs or other projections or by
recesses. Projecting from the centre of the said concave part there is, or may be,
a short sharp spike which when made in metal may form one end of the shank part
to which the concave part is fixed. The concave shape of the crusher prevents it
from slipping off the lump of sugar and by employing the said internal projections
the crushing is facilitated.
On the accompanying sheet of drawings to which I will now refer are illustrated
various forms of sugar crushers constructed according to this invention.
In all the figures A is the stem of the sugar crusher and B is its enlarged
lower end.

page_text: The sugar crusher shewn in elevation by Fig. 1 and in inverted plan by Fig. 2
has its concave end B roughened by alternate radial ribs c and recesses d.
Fig. 3 shews a sugar crusher having its lower end B made the same as that shewn
by Figs. 1 and 2 but the stem A is produced through the lower end B to form the
sharp central spike e to facilitate crushing the sugar; the other forms of sugar
crushers herein described can be similarly made with a spike e.
Figs. 4 and 5 represent in sectional elevation and in inverted plan another form
of my improved sugar crusher in which the concave lower end is roughened by
concentric ribs or corrugations f and g.
In the sugar crusher shewn by Fig. 6 the concave lower end B is made smooth
underneath; and in that shewn by Figs. 7 and 8 the concave lower end B is
roughened by having small spikes & projecting from its inner surface.
The sugar crushers shewn by Figs. 1, 2, 3, 4, 5, 6, 7 and 8 are all made of metal
and their lower ends B can very conveniently be made from sheet metal blanks
stamped or pressed by dies of corresponding form.
Figs. 9 and 10 illustrate my invention applied to a sugar crusher made of glass
its concave lower end B being roughened by alternate radial ribs c and recesses d.
Or the lower end B of the glass sugar crusher may be roughened in any of
the other ways hereinbefore described and shewn on the drawing as applied to metal
sugar crushers.
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:-
Making the enlarged lower end of a sugar crusher of a concave or hollowed form
underneath either smooth (Fig. 6) or roughened (Figs. 1, 2, 3, 4, 5, 7, 8, 9 and 10)
for the purpose and substantially as hereinbefore described and illustrated by the
accompanying drawing; and whether made with the central spike e as and for the
purpose stated or not so made.
Dated this 5th day of September 1891.
