I, ADOLF VON BABO, Maschinen-fabrik Neurod, Ettlingen, Baden Germany do
hereby declare the nature of my invention for CONTEMPORAL, ACCURATE AND
SMOOTH WORKING OF THE SIDES OF A NUMBER OF HEXAGON-NUTS OF EQUAL SIZE
to be as follows:-
On a stand a slide moves up and down in a vertical prism-guide. A thorn (or
bolt) with horizontal axis attached to the slide seizes with a slide-wheel fastened
on the free end into the eccentric slit of a disk with horizontal axis. By turning
the disk there results each time a periodical up-and down-motion of the slide. The
slide bears three spindles arranged parallel and horizontal, on the one end of which
there are worm-wheels for moving the spindles, and on the other two shaping-
disks at a time with lateral teeth. The motion of the spindles as well as of the
disk with eccentric slit is produced by means of an endless screw and this finally
by a transmission-shaft.
Under the shaping disks there is a removable work-table with six mandrils,
standing in the order of a regular hexagon for receiving six sets of nuts, of which
three sets are at the same time worked upon at the going up and down of the slide.
After each single up-and down-movement of the slide, the table is turned one sixth
of its circumference and is held in this position by means of a latch.
The mandrils, which become free after each one sixth revolution are prepared
anew while the machine is performing its work.

I, ADOLF FREIHERR VON BABO, Neurod near Ettlingen, Baden, Germany,
Engineer do hereby declare the nature of my invention for "IMPROVEMENT IN
NUT-SHAPING MACHINES" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:—
On a frame with a round table T revolvable around a vertical axis there is a
slide S going up and down in a vertical direction. Besides the frame has a
and the worm wheel d, a
principal shaft a, a shaft, b with an excentric, dineel & and a worm wheel g.
shafte with endless screw f, fitting into the'
The shaft h, with endless screw fitting into the worm wheel g, is driven by the
principal shaft a by means of the bevel wheels m. The vertical shaft at its upper
end is conducted by the slide S, which moves up and down.
On the slide are three horizontal spindles n, on the foreend of which are two
shapers o as tools, on the hind end of which are worm wheels p, which receive their
motion by the principal shaft by means of bevel wheels and a spiral shaft q.
The tools, shaping discs of greater circumference and laterally toothed, performe
their work on the nuts, fastened cylindrical mandrils t in such a manner, that at the
same time two parallel sides of the nuts on each mandril are acted upon by two
The
shapers of each spindle by the up-and downward motion of the slide.
round table T revolvable about a vertical axis bears on its upper surface the above
mentioned vertical mandrils t, arranged so as to form a regular hexagon with the
nuts fastened upon it. Three of these mandrils are at the same time brought
under the space of two shaping discs and are kept in position by the latch 8, which
falls into six notches 7, in the circumference of the table, while the shaping of two
parallel sides of the nuts on the before mentioned three mandrils takes place as
described.
The, up and down motion of the shapers is produced by the connecting pivot u,
working automatically by means of the eccentric c, which by its special angles of
inclination causes a periodical stop, faster and slower up and down motion of the
slide, rest of the tools.
i
After each period, the table is turned 1/6 of its circumference and a mandril is
prepared anew The entire motion of the machine excepting the 1/6 revolution
results automatically in equal periods by the principal shaft.
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
A shaping machine for contemporal working of the six sides of a number of nuts
of equal size, with the following contrivances illustrated by the drawing.
1. The revolvable working table T with six mandrils arranged in the order of a
regular hexagon for receiving six sets of nuts of which three sets are at the same
time shaped on two sides with latch 8, by which the table is arrested after each 1/6
revolution,

going up and down.
3. The mechanism for moving the slide up and down, consisting of the disc c,
moved by the worm wheel gear d.
