I THEODOR BAUM of N° 30° Müller Strasse in the City of Berlin, Prussia,
Germany, Mechanic, do hereby declare the nature of my Invention for "A MACHINE
FOR SIMULTANEOUSLY SHAPING SEVERAL SURFACES OF NUTS AND OTHER PRISMATIC
"
BODIES 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 a new machine by means of which several surfaces of
regular prismatical bodies, such as screw-nuts, bolts, fittings, as well as cocks,
water guages etc., may simultaneously be operated upon both in a horizontal as
well as vertical direction, and consists more particularly in the employment of a
number of cutter-holders which operate together in an exact and accurate manner
and can simultaneously be put into operation. The chief advantage which this
machine has over all other existing machines, is based upon the application of the
vertical and horizontal planing or shaping machine, in which several objects, such
as screw-nuts for instance, can be simultaneously operated upon, without a change
of the constructive parts of the machine being required, the motive power and
mechanical parts alone being operated in different ways, according to requirement.
Fig. 1, represents a top-view of a machine for planing hexagonal screw-nuts, in
which for the better understanding, part of the cutter-holders are removed.
Fig. 2, is a side-view and a partial cross-section, and
Fig. 3, is the front-view of the machine.
The supports b, with wedge-shaped grooves, are screwed on to the hexagonal
base plate a, which said supports or standards carry the slides c, and can be
adjusted in lateral direction. These slides carry the cutter or tool-holders d, which
with their cutters e, can be adjusted in a central direction and are fixed or kept in
position by a screw f, the nut of which is omitted in the drawing. The cutters ė,
are secured or fixed in the cutter-holders by pressure-screws g, while the adjust-
ment of the said cutters in the slide c, is effected by a piece of metal h, screwed to
the front lug of the cutter-holder, which said piece h catches into a slot i, of the
slide and is operated by a screw k, which is arranged in the slide c. A tube l, is
arranged in the base plate a, and carries at its upper end a disc m, provided with
a number of recesses n, corresponding with the number of cutter-holders. A second
disc o, with the same number of corresponding recesses is arranged above the

page_text: disc m, and, is capable of being adjusted by means of the screw p, or if the same
should be worn out, can be readily replaced by a new disc; in order to obtain an
exact movement of the slides c, a perforated sliding cube or other suitable piece of
metal q, is inserted in each of these recesses and is fastened to the slide by means
of the screw T.
The object operated upon-in this case a screw-nut,-is screwed on to the stem
or rod t, in the centre of the machine, and the operation of planing in a vertical
direction is carried out as hereafter described. It must here be observed that any
appropriate driving mechanism can be employed, and is therefore not shown in the
drawings.
When planing in a vertical direction, two cutters are employed, of which the one
cutter e, serves as gouging tool, while the second cutter e, acts as smoothing chisel
or tool. These cutters are first placed in proper position to each other and rigidly
fixed by a clamp 8, after which they are brought into nearly their required positions
in the cutter-holder and fixed in the latter by the screws g, while the cutter-holder
is accurately adjusted by the set-screws k, and fixed in the slide by the screw f.
By means of some suitable mechanism, a vertical movement is now given to the
stem or rod t, while the tube 7, is caused to make an automatic intermittent rotating
movement after every double stroke, which movement can, for instance, be produced
by a worm and worm-wheel, so that the said tube 7, is caused to make a partial
revolution. By means of this arrangement, the inserted pieces in the recesses n,
will cause the slide, and with the same, the cutter-holders to be laterally adjusted,
corresponding with the paring or cut of the cutting instruments.
When the object operated upon is finished, the worm-wheel is brought out of
gear, and by simply turning the tube 1, the whole system of cutter or tool-holders,
is returned to its original position, without the necessity of putting every single
cutter-holder back to its former position.
My construction, which permits the employment of two cutters for planing in a
vertical direction, also has the advantage, that on the breaking of the gouging
tool e, it is not necessary to exchange the same, as the smoothing chisel e¹, will
continue to do the work until the object is finished.
For planing in a horizontal direction, which must, for instance, be done with
objects provided with flanges, one cutter 6, only is employed, as illustrated by the
upper part of fig. 1.
The tool-holders are adjusted and fixed as before described, and the tube 1,
receives an oscillating movement from the worm and worm-wheel or in other
suitable manner, which causes the slide to glide to and fro upon the supports,
.whereby the tool is carried up and down along the surface of the object under
treatment.
After every double stroke, the stem t, is raised by the breadth of the paring or
cut if worked downwards, or it is lowered in the same proportion if worked
upwards. When the article is finished, the stem or rod is raised and another object
inserted, while at the same time, the mechanism for operating the worm is brought
out of gear.
In order to remove the parings or cuttings from the machine while the same is
at work, the supports and base plate a, are provided with six slots u, through
which as well as through the tube 1, the said, parings or cuttings are carried off
from the machine.
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 machine for simultaneously operating on or treating several
surfaces of regular prismatical bodies in a horizontal as well as vertical direction
characterised by

of the supports b, which said slides, through. the oscillation of the central tube
