New Pick for Dressing Mill-stones.
1, EMIL NEELSSEN, Painter, at Hamburg, Canalstrasse 45, Uhlenhorst, in
Germany, 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:-
Picks for dressing mill-stones cannot be used with ordinary handles as they
would fly off after a very short time, even after dealing but a few blows on the
very hard mill-stone. For this reason encircling devices were resorted to, but up
to date in a very primitive manner.
In the following improved tool the inventor offers the first really useful instrument
answering all requirements.
In the annexed drawings:
Fig. 1 is a front view of the tool without the steel-pick.
Fig. 2 shows the same with the pick fitted.
The handle (a) is fitted on its thickened top (6) with an iron hoop (c) pierced on
both its lateral sides. In this hoop (c) and its piercings (d) a pressure-plate (e) is
moveable up and down, by means of a screw (f) and thumb-nut (g). The plate (e)
is connected with the screw (f) by means of a ball- and socket-joint. In order to
secure the pick (4) the lateral superficies of which are rhomboidal, a wedge (i) is
introduced from behind, through the piercings (d) of the iron hoop (c) on whose
slanting superficies reposes the pick (4) pressed down by means of screws and the
pressure-plate.
The base (i) is secured against shifting by means of a groove (k) encircling a
protruding band (1) of the head (b) so that an absolute immobility of the pick can
be warranted.
According to the habit of the workman the pick (4) may, by shifting the base (i)
be approached to or removed further from the handle or from the operator, by
securing the tool either by means of the groove (k 1) or (k2). By increasing the
gradient of the slope of the base; as for example (i) in Fig. 3, the pick (4) can be
given a greater inclination towards the handle the which is often desirable. This
new device offers furthermore the advantage, that thinner picks may be used, thus
reducing expenses. Hitherto the customary pickholders grasped the steel-pick in
the middle and, the sharpening of the tool being thus feasible only up to a certain
limit, great waste of material obtained in the above manner of securing picks,
whereas in our new device sharpening can be continued on both sides much longer;
in fact as long as a fastening will still be practicable.
The device represented in Fig. 4 is destined for those who prefer to continue
using thicker picks, as represented in (m), these handles being fitted with a flatter
base (n) this latter arrangement allowing also of the picks being used up to a
mere stump.
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:
The invention of a mill-stone pick the particular feature of which is a pierced
hoop (c) fitted on the top of the handle and destined for the admission of the pick,
this latter resting on a wedge-formed base (i) kept in its place by means of a groove

page_text: and tongue, the gradient of the wedge determining the pick's inclination towards
the handle and the pick being rendered immovable by a pressure-plate (e) whose up
and downwards movement within the hoop (c) is effected by the screw (f) connected
with it by means of a ball and socket-joint."
