An Improved Milling Attachment for Lathes.
I, AUGUST KUTSCHER, manufacturer of Weissenburg in Alsacia, country belonging
to the German Empire do hereby declare the nature of this invention to be as
follows:-
This invention relates to a shaping mechanism, which can be applied directly to
any lathe, thus rendering the employment of special shaping machines unnecessary.
This apparatus is not only intended to shape wheels of every kind in a clean and
accurate manner ¡but also flutet cylinders, mandrels, grooves and in general all
objects which can be attached between the centres of the lathe.
The arrangement is best fitted, therefore, for workshops, where repairs are done
and the expense of a special shaping machine would not be justified.
The apparatus consists essentially of two parts, the shaping contrivance and the
dividing contrivance.
The first contrivance is shown in the accompanying drawing in fig. 1 in side view
and in fig. 2 in front view; the latter is shown in figs. 3 and 4 in front and side
view to the lathe.
The shaping contrivance consists in the angle piece G, provided with bearing
supports for the movable parts, and fastened with the screw s¹ upon the upper slide a
of the support of the lathe, the pulley e, driven by a cord, the corresponding
conical wheels p and q the latter placed on the upper end of the vertical shaft r and
the milling cutter t, placed exchangeable on the shaft r and fastened with nut u.
Figs. 1 and 2 show the cutting of a groove into an axle W by means of the milling
cutter t.
The axle W lies alongside to the lathe fixed between the centres thereof.
The slide a with the shaping contrivance thereupon is movable along the lathe on
the slide b, which is movable across to the lathe on the ground plate of the support.
The dividing contrivance which is employed when the shaping contrivance has not
to shape a single rabbet, but cog-wheels, fluted rollers, broachs and the like, consists
in the following.
On the iron D, which is fixed across in front of the lathe on the end of the head-
stock, and swings with its round end d on the bearing of the guide-screw surrounding
the end of the latter is fastened the bracket E by means of the screws sa lying in the
slits S; this bracket bears above in corresponding eyes the axle f provided with a
worm H. The one end of the axle f supports a bracket n and a cog-wheel h, which
gears with another cog-wheel h¹; the axle i of this latter is placed capable of being
turned in the bracket n and bears in front a collar with the crank l, acting as a
spring, which slides on the edge of the division disc k.
The latter is placed between the collar and the cog-wheel h, and prevented to turn
with the axle i by screwing to an angle frame w.
The crank in turning catches into the recesses v of the edge of k and is fixed in
this manner.
The worm H on the axle f gears with a helicoidal wheel g, which is placed on the
axle m of a change wheel on the headstock.

When the first cog is shaped, the crank according to the desired division and the
proportion of the change wheels h and h¹ is turned over half the circumference or
once or twice over the whole circumference of the division disc k, and now fixed by
means of the catching in one of the two recesses arranged opposite to each other.
By this turning also the axle f, the worm H and the helicoidal wheel g are revolved
correspondingly, so that by means of the change wheels likewise are revolved the
mandril and the cog-wheel or an other work-piece, fixed between the centres of the
spindle of the headstock and of the shifting-head.

An Improved Milling Attachment for Lathes.
I, AUGUST KUTSCHER, manufacturer of Weissenburg in Alsacia, country belonging
to the German Empire 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:
This invention relates to a shaping mechanism, which can be applied directly to
any lathe, thus rendering the employment of special shaping machines unnecessary.
This apparatus is not only intended to shape wheels of every kind in a clean and
accurate manner but also fluted cylinders, mandrels, grooves and in general all
objects which can be attached between the centres of the lathe.
The arrangement is best fitted, therefore, for workshops, where repairs are done
and the expense of a special shaping machine would not be justified.
The apparatus consists essentially of two parts, the shaping contrivance and the
dividing contrivance.
In the drawing, filed with the provisional specification, the first contrivance is
shown in fig. 1 in side view and in fig. 2 in front view; the latter is shown in figs. 3
and 4 in front and side view to the lathe.
The shaping contrivance consists in the angle piece G, provided with bearing
supports for the movable parts, and fastened with the screw 8¹ upon the upper slide a
of the support of the lathe, the pulley e driven by a cord, the corresponding conical
wheels p and q the latter placed on the upper end of the vertical shaft and the
milling cutter t placed exchangeable on the shaft r and fastened with nut u.
Figs. 1 and 2 show the cutting of a groove in an axle W by means of the milling
cutter t.
The axle W lies alongside to the lathe fixed between the centre-punches thereof.
The slide a with the shaping contrivance thereupon is movable along the lathe on
the slide b, which is movable across to the lathe on the base plate of the compound
rest.
The dividing contrivance which is then employed when the shaping contrivance
has not to shape a single rabbet, but cog-wheels, fluted rollers, broachs and the like,
consists in the following.
On the iron D which is fixed across in front of the lathe on the end of the
headstock, and swings with its round end d on the bearing of the guide-screw,
surrounding the end of the latter, is fastened the bracket E by means of the screws 8 8
lying in the slits S; this bracket bears above in, corresponding eyes the axle f
provided with a worm H. The one end of the axle f supports a bracket n and a
cog-wheel h, which gears with another cog-wheel h¹; the axle i of this latter is placed

page_text: capable of being turned in the bracket n and bears in front the crank l, acting as a
spring, which slides on the edge of the division disc k.
The latter is placed between the bound and the cog-wheel h¹ and prevented to turn
with the axle i by screwing to an angle frame w.
The crank in turning catches into the recesses v of the edge of k and is fixed in
this manner.
The worm H on the axle f gears with a helicoidal wheel g, which is placed on the
axle m of a change wheel on the headstock.
The process for shaping and dividing is as follows.
When the first cog is shaped, the crank according to the desired division and the
proportion of the change wheels h and h¹ is turned over half the circumference
or once or twice over the whole circumference of the division disc k, and now
fixed by means of the catching in one of the two recesses v arranged opposite to
each other.
By this turning also the axle f, the worm H and the helicoidal wheel gare
revolved correspondingly, so that by means of the change wheels likewise are
revolved the mandrel and the cog-wheel or an other work-piece fixed on the
centres of the spindle of the headstock and of the shifting head.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
Shaping contrivance simply arrangeable on all lathes, characterized by the
arrangement of the angle piece G, supporting the motion disc e, and the axles v
and y, standing at (a right angle to one another, with the corresponding conical
wheels p and q, and the milling cutter t on the axle r, upon the upper slide a
of the support-fix; of the lathe in connection with the worm H, which is
fastened on the axle f and situated over the bracket E, fixed on the iron D in
front of the lathe, and gearing in the helicoidal wheel g on the axle m of a
change wheel of the lathe, the change wheels h and h', the division disc k,
fastened by the angle bracket w, and the axle i of the change wheel h¹, going
through the division dise, and supporting in front the crank l.
