in the Kingdom of Prussia, Manufacturers, for the Invention of
A NEW FILE-PLANING MACHINE.".
PROVISIONAL SPECIFICATION left by the said Hermann Moritz and
Jacob Reinach at the Office of the Commissioners of Patents, with
their Petition, on the 31st July 1868.
We, HERMANN MORITZ and JACOB REINACH, of Berlin, in the
Kingdom of Prussia, Manufacturers, do hereby declare the nature of
the said Invention for "A NEW FILE-PLANING MACHINE," to be as
follows:-
}
This Invention relates to a file-planing machine for the purpose of
planing files worn out by use, so as to enable them to be re-cut and
rendered useful.
In order to accomplish this a planing steel or cutter is firmly fixed in'
a stock on the upper part of the frame of the machine above the file to

page_text: be planed, and the file is conducted beneath it in a curved path so as to
bring the varying level or taper of the file under the planing steel.
In the frame of the machine parallel rocking bars are set on axles,
and their ends meet midway in the machine underneath the plane. The
elevation of these rockers is regulated by a crank and shaft turning
a vertical bevil wheel, which gears with a horizontal bevel actuating a
vertical screw shaft which elevates and depresses the rockers, above which
the sliding carrier gripping the file is set, such carrier being moved
with a reciprocating motion after the manner of an ordinary metal-
planing machine. The gripper or pincers consists of two claws or
clamps, compressed together or widened by a screw, so as to enable
them to grasp the varying lateral taper of the file. The pincers or
grippers are caused to rise and fall to suit the thickness of the file by
ordinary adjusting screws. The requisite pressure of the plane steel
upon the file is produced by a lever pressing upon a sliding holder in the
stock above mentioned.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said
Hermann Moritz and Jacob Reinach in the Great Seal Patent
Office on the 10th February 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HERMANN
MORITZ and JACOB REINACH, of Berlin, in the Kingdom of Prussia;
Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of July, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Hermann Moritz and Jacob Reinach,
Her special licence that we, the said Hermann Moritz and Jacob
Reinach, our executors, administrators, and assigns, or such others
as we, the said Hermann Moritz and Jacob Reinach, our executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and

page_text: vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "A NEW FILE-PLANING
MACHINE," upon the condition (amongst others) that we, the said
Hermann Moritz and Jacob Reinach, our executors or administrators, by
an instrument in writing under our, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Hermann Moritz and Jacob
Reinach, 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 (that, is
to say):-
-:
:
The file-planing machine represented in the accompanying three
Sheets of Drawings is principally intended for planing arm and smooth
files worn out by long use, in lieu of the present expensive whetting
process they were hitherto subjected to previous to their being cut. A
file.of four pounds weight requires upwards of twenty minutes whetting,'
whilst its planing is completed in one minute.
The peculiar longitudinal form of the files requires a special construc-
tion of machinery, and the chief advantages of our machine are as
follows, viz.-A firmly fixed planing tool, and the file being conducted
under the said tool in a curved path.
The frame of the machine contains the parallel rocking bars a, a,
and a, a, revolving round the axes 6 and 6', Sheet 2, Fig. 2, and
Sheet 3, Figs. 4 and 5. Their inclination towards each other is
changeable, as their ends a, a, rest on the props d, and the latter can be
raised and lowered by the crank e, conical wheels f, and screw g, see
Sheet 2, Fig. 1, and Sheet 3, Fig. 3.
On the upper edges of the parallel bars rest the four vertical con-
ducting pieces h, Sheet 2, Fig. 2, placed in seats in which there are the
pins p¹, Sheet 3, Fig. 9, of the resting piece o for the cradle i, the
pieces h moving in the spaces B of the sledge or carrier k, and the latter
being conducted in any well-known manner by the strap pulley / and
screw axle m (Fig. 2, Sheet 2, and Figs. 6 and 7, Sheet 3), upon the
side beams in a straight line. The middle of the-cradle i, Fig. 2; Sheet 2,

page_text: is moved in a gently sloped curve corresponding to the file, and this
curve is through the construction of its joints rather yielding to the
position of the planing tool.
Round the cradle i lie the pincers P, Fig. 2, Sheet 2, and Fig. 2,
Sheet 3, that hold the file q; these pincers are suspended in the cradle,
so that their position can be changed according to the thickness of the
files, and a proper varying regulation of their position obtained.
With regard to the pincers the bows are screwed at E, Fig. 1,
Sheet 3, to the cradle, and the two axles & lead into the cavities (Figs. 1
and 8, Sheet 3) of the cradle. By turning the screw t the pincers rise
and by actuating the axles which works in bearings u, Fig. 2, Sheet 3,
the two sides of the pincers grasp the file, the lower plane of which rests
on the axle v.
The requisite pressure of the planing tool upon the file is produced by
a weighted lever x, Sheet 2, Fig. 1, pressing upon the sliding piece w in
which the tool is fixed.
The remaining arrangements of the machine represented in detail,
Sheets 1 and 3, are easily understood as they are similar to the common
joiner's bench.
Having thus described the nature and particulars of our said Invention,
we claim, the file-planing machine as described and illustrated in the
accompanying Drawings.
In witness whereof, we, the said Hermann Moritz and Jacob
Reinach, have hereunto set our hands and seals, this Twenty-sixth
day of January, in the year of our Lord One thousand eight 2
hundred and sixty-nine.
