Improvements in and relating to Apparatus for Grinding Salt,.
Spices, and other Substances.
I, JACQUES LOUIS HEYERMANN, of 78 Glauburgstrasse, Frankfort on the
Main, in the Empire of Germany, Architect, 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 :-
My invention relates to hand-mills for grinding salt, spices, and other substances,.
which substances can also be kept in my improved hand-mill and protected from air
and dust till required for use.
My invention will be readily understood by reference to the accompanying sheet
of drawings, in which
Fig. 1 is a section of my improved mill for table service, and Fig. 2 is a similar ·
section with the grinding spindle & removed.
Fig. 3 is a plan of the removable lower part of the mill.
Fig. 4 is an elevation of the whole mill.
Figs.
and 6 are respectively section and elevation of another form of my
improved mill, for grinding and storing larger quantities of material, adapted for
kitchen use, in which the power is increased by operating with a cranked handle-
instead of a milled head, and the capacity is increased by adding a drawer under--
neath the mill.
a is a glass plate or disc resting on the top of the salt or other substance, and
forced down by a spring so as to keep up the supply passing b and g so long as
there is any of the said substance left in the mill. is the movable part of the
grinding apparatus, which is preferably of conical shape, as shewn. C is the shaft.
by means of which the cone is rotated by a milled head e, secured to the said
shaft C by a catch or key d. g is a triangular or star-shaped piece supporting the
grinding cone b, down the sides of which piece g the ground material passes to the
delivery orifice f. h indicates the removable lower part of the mill, which is screwed
onto the upper part, as shewn, and kept from moving, when so screwed on, by the
washer screwed down tightly against it. K, Fig. 5, is the crank or handle which.
replaces the milled head e of Fig. 1.
The form of mill shewn in Figs. 1, 2, 3, and 4 is intended to be used on dining
tables to replace the usual salt cellars or other receptacles for seasonings and the-
like, the milled head being turned to pulverize a small quantity of the contents,.
which passes through the delivery orifice fas required. By this means, the salt is
not contaminated whilst in use, as often happens in hotels and eating-houses; the
labour of cleaning and replenishing the salt cellars is reduced; and the ordinary
coarse salt as used in the kitchen may be placed in these mills for table use, instead
of the so-called table salt, which is dearer and less pungent.
The form of mill shewn in Figs. 5 and 6 will pulverize salt, spices, and the like
with the same advantages as above described, and in less time and with less labour
than by the means at present employed.
When used for salt, the mill must be made of materials which will not act
injuriously on the salt, and which will not be itself affected by the salt.
In order to regulate the fineness to which the materials are to be ground, the
lower part of the apparatus is screwed up or down on the other part, thereby
moving up or down the part g, and with it the grinding cone b, which reduces or
enlarges the space left between the grinding cone 6 and the shell of the apparatus,
and thereby regulates the fineness of the ground materials which can pass through.
such space.

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. In hand-mills for grinding salt, spices, and the like substances, the glass disc
or plate a operated by spring for feeding such substances downwards to the grinding
cones, as herein set forth.
2. In hand-mills for grinding salt, spices, and the like substances, the means
for regulating the fineness to which such substances are to be ground, substantially
as herein set forth.
3. The general construction, arrangement, and combination, of all the parts
comprising my improved apparatus for grinding and storing salt, spices, and other
substances for table use.
Dated this 13th day of March 1894.
