We, BERNHARD ERCKEL of 28 Rosenstrasse, Dresden, in the Empire of Germany,
Merchant, and REINHOLD ENGELHARDT, of Alt. Coschütz near Dresden aforesaid,
Locksmith, do hereby declare the nature of our said invention 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 our invention is to manufacture an improved form and arrangement
of apparatus for sharpening scythes.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a plan of our apparatus; Fig. 2 is a back view; Fig. 3 a front view, and
Fig. 4 a section on the line y z.
hh are two levers pivotted to the block and held in position by washers and
screws a.a. The short ends of these levers bare fitted with hardened steel rollers c c
capable of revolving on pins e e. The arms serve as handles to the apparatus.
m m are two plates of hardened steel, having their inner edges slightly bevelled.
These plates are fixed to the block by the plate p and screws s s s.
The plate w is fixed to the block by the screws i i. is a grooved pulley fitted
in the jaws of a bracket k, and screwed to w by the screw ; the bracket having a
slot k¹, to render it adjustable for raising or lowering the pulley g.
The steel plates m m are so fixed and adjusted that their cutting edges form a
V-groove or tapered slot, the edges being sufficiently sharp and hard to cut or shear
off some of the metal of the scythe blade, as in planing metal. The rollers c c can be
adjusted by means of the screws a and thumb screws; and these rollers c c together
with the grooved pulley servo for the guidance of the scythe requiring to be
sharpened.
Also by means of the thumb screws f the levers bb may be placed in such a manner
that the rollers cc may be brought closer to or farther from one another, or so
that they may press the scythe more or less against one or the other of the steel
plates m m.

page_text: In order to sharpen a scythe, the apparatus is placed upon the scythe in such a
manner that the cutting edge of the scythe may enter the tapered slot formed
by the steel plates m m and pass between the rollers cc and the groove of the guide
pulley g.
The apparatus being now held by its handles h h and drawn along the cutting edge
of the scythe blade a thin shaving of metal is sheared off the sides of the cutting
edge of the blade by the sharp edges of the plates m m leaving an entirely smooth
cutting surface.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The improved apparatus for sharpening scythes, having steel plates m m, acting
as cutting planes upon the cutting edge of the scythe blade; such blade being guided
by the pulley g, and the rollers c c fitted to the short ends bb of levers h h, adjustable
relatively to each other and to the steel plates by thumb screws ff, substantially as
herein-before described and shewn on the drawings.
2. The general construction, combination, and arrangement of the several and
respective parts, together- forming our invention of an improved apparatus for
sharpening scythes, substantially as herein-before described and shewn on the
drawings.
