Improvements in or relating to Machine-tools for Turning, Drilling,
Boring, Milling, Planing, or Shaping Metals and other Materials.
I, IGNATZ ROEDERER, of 11, Langegasse, Prague, in the Empire of Austria,
Merchant, do hereby declare the nature of this invention to be as follows:-
It is a well-known drawback in working various materials that each of the
finishing operations on a single artice, such for instance, as planing, drilling,
turning, milling, in a vertical as well as in a horizontal direction etc. must be
effected on a separate machine and chiefly in one direction. The result of this
is that to completely fit out a workshop is exceedingly expensive, which drawback
18 remedied by the employment of the machine forming the subject of this applica-
tion. The main feature is the combination of a rotating interchangeable tool
with an adjustable reciprocating one. The planes in which the turning as well
as the planing tools work, can be determined in any desired manner, so that all
the operations in which a reciprocating movement of the tools required, may be
effected with the same planing tool, whilst a turning tool which when desired may he
replaced by a milling cutter or a drill etc. does turning work, the tool in this case
making the main (turning) movement.
The machine according to the present invention is constructed so that the
different interchangable tools on it can work either two simultaneously or eacli
independently so that it becomes possible for instance to plane and drill simul-
taneously and on the same machine. The device for giving proper feeding motion
(movement through the length of a thickness of a shaving) to the object to be
treated which is secured to the support is arranged in the well-known manner
and consists of an intermittingly acting mechanism actuated from the main shaft.
The automatic advance of the two when drilling fresh holes or finishing cast ones
in the horizontal and vertical position of the spindle is effected in the well-
known manner from the drill spindle.
The machine consists of a main column cast in one with a foundation plate,
and connected with a casing in which is supported a driving-spindle or shaft.
The latter may be driven by a belt for which purpose there is mounted on the spindle
a conical pulley. In order to enable hard metal to be worked such for instance
as cast steel or in order to enable a heavier cut to be made in cast iron a second
undershaft is arranged in the usual manner.
The shaft can also be operated by hand by means of a handwheel or from a
driving head stock by means of a belt.
The casing or frame is provided at each side with discs through which pass
spindles respectively actuating the turning tool and the planing tool. Motion
is communicated to said spindle from the main shaft by means of bevel-wheels.
The connection of the turning and planing device with the casing or the driving
of the two tools is effected as follows;-
The divided or forked bearing supporting the longitudinally adjustable turning
spindle is connected by arms to a disc which can be secured by bolts on the disc

page_text: one side of the casing referred to. To enable the turning tool to work in different
planes, the heads of the bolts are adjustable in 'the circular grooves of the discs so that
the turning tool may be easily placed and secured in any desired position. To
completely ensure the turning tool remaining in its horizontal or vertical position,
pins are used which are placed partly in the two discs. The turning tool is
operated by bevel wheels. To the second disc of the casing is connected a disc in
a similar way to that in which the discs actuating the turning tools are connected.
The disc is provided with a central hole through which passes the driving spindle
operated by means of bevel wheels. The planing tool is guided in its motion
in guides which form one piece with the disc by means of arms.
The planing
tool is caused to reciprocate in well known manner by adjustably connecting one
end of a link, passing through an opening in the upper arm, to the planing tool,
the other end of the link being radially adjustable on a disc rotated from the
driving spindle, whereby a reciprocating motion is given to the tool.
To enable this machine to be also used as a shaping machine, there is provided
a second tool-holder in which the tool is placed at right angles to the cutting tool,
so that by turning the disc through an angle of 90°, and by securing it in said
position, the machine is converted into a shaping machine.
The object to be worked is placed, according to the operation to be effected, either
on a cross-shaped plate or support below the cutting tool or on a face-plate below the
turning-tool or across both, said plates being arranged on arms or supports sur-
rounding the main column. The arms are movable along and round this column,
the first motion being communicated to them by a worm-gear and a rack on the
main column, the two arms being secured together by bolts after having been
turned round the column.'
The working of the machine is as follows:-
In order to enable to work either only with one tool or with both simul-
taneously, the bevel-wheels are loose on the driving spindles and the latter are
driven from the main shaft only when the bevel-wheels are coupled to their
respective spindles as by keys. If the machine is to be used as, say, a vertical
drilling machine, the turning tool occupies the vertical position and the object to
be drilled rests on the face-plate or on the cross-shaped support. The object to
be drilled is secured, and the drill-spindle makes the main (rotary) as well
as the feeding (longitudinal) motion.
In order to enable exact drilling to be done in a horizontal direction, the first
thing to do, is to turn the disc on the casing through an angle of 90 and to secure
it in this position by pins and by tightening the bolts.
The object to be operated upon is secured on the face-plate or on the support,
and thus either the drill-spindle (or its extension) which may be guided,
if desired, in a suitable guide at the back, may make both the main and the feed-
ing movement, or the drill spindle makes only the main movement, the feeding
motion being given to the object together with the support.
When used as a slot-drilling machine, for instance for making grooves for keys
in shafts, the turning spindle is again vertical and the object to be operated upon
is secured on the cross-shaped support. The turning spindle makes therefore
in this case the main (rotary) movement and also the vertical feeding motion to
advance the length of one cut, the horizontal feeding motion being made by the
part operated upon.
If the machine is to be used as a lathe, then the spindle is arranged horizontally
and after the tool has been removed from the drill-spindle, the face-plate is screwed
on to the latter and the work is fixed to this face-plate. The tool is fixed in a
tool-holder secured to the support and makes the feed-motion, the work making
the main rotating movement. The work, however, may also have a feeding
motion as well, if it has a cylindrical surface..
If it is desired to use the turning device as a milling machine, then the face-
plate is removed from the drill-spindle, the latter is provided with a shaft to

page_text: .
receive the milling cutter or is replaced by a suitable milling cutter. The work
is fixed on the support, or if the cutter-spindle is to have a feeding (longitudinal)
motion, instead of the work, then the latter is fixed on the face plate or table.
This operation can be effected-with very great advantage on the machine according
to the present invention, as only one setting or adjustment of the work is required,
even if the latter is to be cut on different surfaces. If fixed on the support the
work has the feeding motion and the cutter the main (rotary) motion.
If the machine is to be used as a slotting machine then the planing tool is
vertical and has the main (reciprocating) motion, the work fixed on the cross-
shaped support making the feeding motion.
When used as a shaping machine the cutter is placed in the tool holder and its
disc on the casing is turned through an angle of 90°. The work is fixed to the
support and performs the feeding motion, the main motion being communicated to
the tool:
The work can therefore be done much quicker as it is very easy, by 'simply turn-
ing the arms on the main column, to bring the work, once properly set, from the
turning device under the planing device, or vice versa, or to perform both
operations simultaneously.

Improvements in or relating to Machine-tools for Turning, Drilling,

I, IGNATZ ROEDERER, of 11 Langegasse, Prague, in the Empire of Austria,
Merchant; 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:-
It is a well-known drawback in working various materials that each of the
finishing operations on a single artice such for instance as planing, drilling,
turning, milling, in a vertical as well as in a horizontal direction etc., must. be
effected on a separate machine and chiefly in one direction. The result of this
is that to completely fit out a work-shop is exceedingly expensive, which drawback
is remedied by the employment of the machine forming the subject of this applica-
tion. The main feature is the combination of a rotating interchangeable tool
with an adjustable reciprocating one. The planes in which the turning as well
as the planing tools work, can be determined in any desired manner, so that all
the operations in which a reciprocating movement of the tool is required may be
effected with the same planing tool, whilst a turning tool which, when desired, may
be replaced by a milling cutter or a drill etc., does turning work, the tool in this case
making the main (turning) movement.
The machine according to the present invention is constructed so, that the
different interchangeable tools on it can work either two simultaneously or each
independently so that it becomes possible, for instance, to plane and drill simul-
taneously and on the same machine. The device for giving proper feeding motion
(movement to the extent of the thickness of a cut) to the object to. be
treated, which is secured to the support, is arranged in well-known manner
and consists of an intermittingly acting mechanism actuated from the main shaft.
The automatic advance of the tool when drilling fresh holes or finishing cast ones,

page_text: in the horizontal and vertical position of the spindle, is effected in the well-
known manner from the drill-spindle.
In the accompanying drawings,
Fig. 1 shows the machine according to the present invention in front-elevation,
Fig. 2 is a plan,
Fig. 3 in side-elevation,
Fig. 4 to 8 being detail views.
The machine consists of a main column a cast in one with a foundation plate b
and connected with a casing c in which is supported a driving spindle or shaft d.
The latter as can be seen from the drawing may be driven by a belt, for which
purpose there is mounted on the spindle da conical pulley f. In order to enable
hard metal to be worked, such for instance, as cast steel, or in order to enable a
heavier cut to be made in cast-iron, a second shaft g is arranged in the usual
manner. The shaft d can also be operated by hand by means of a hand wheel e
or from a driving head stock by means of a belt.
The casing c is provided or formed at each side with discs hh¹ through which
pass spindles and respectively actuating the spindle carrier k and the slide i.
Motion is communicated to said spindles and from the main shaft d by means of
bevel wheels m m¹ m³. The connection of the rotating and planing devices with
the casing c or the driving of the two tools is effected as follows:-
The divided or forked bearing a supporting the longitudinally adjustable
rotating spindle n is connected by arms o¹ to a disc p which can be secured by
bolts p on the disc h (Figs. 7 and 8). To enable the rotatory tool to work in
different planes, the heads of the bolts are adjustable in the circular grooves q
of the disc h, so that the tool may be easily placed and secured in any desired
position. To completely ensure the tool remaining in its horizontal or vertical
position, pins q are used which are placed partly in the disc h and partly in the
disc 2. The tool is operated by bevel wheels ss (Fig. 1). To the second disc h¹
of the casing c is connected by bolts 3 a disc r in a similar way to that in which
the discs h and 2 of the rotating tool are connected. The disc r is provided
with a central hole through which passes the driving spindle / operated by means
of bevel wheels mm². The planing tool i is guided in its motion in guides
which form one piece with the disc r, by means of arms r¹. The planing tool i is
caused to reciprocate in well known manner by adjustably connecting one end
of a link t passing through an opening in the guide arm 2 to the planing tool,
the other end of the link being readily adjustable on a disc rotated from the
driving spindle whereby a reciprocating motion is given to the tool.
To enable this machine to be also used as shaping machine, there is provided
a second tool-holder U¹ in which the tool is placed at right angles to the cutting
tool u on its holder U so that by turning the disc through an angle of 90°, and by
securing it in said position, the machine is converted into a shaping machine.
The object to be worked is placed, according to the operation to be effected,
either on a support below the cutting tool or on a face-plate v below the turning
tool, said parts being arranged on arms or supports 2 surrounding the main
The arms are movable up and down and around this column, the
first motion being communicated to thein by a worm-gear N and a rack a¹ on the
main column a, the two arms being secured together by bolts w after having
been placed in the desired position round the column a.
The working of the machine is as follows:-
column a.
In order to enable work to be done either only with one tool, or with both
simultaneously, the bevel-wheels m¹ m² are arranged loosely on the driving
spindles and the latter are driven from the main shaft d only when the bevel-
wheels m¹ m² are coupled to their respective spindles as by keys xy. If the
machine is to be used as, say, a vertical drilling machine, the turning tool occupies
the vertical position shown in Figs. 1 to 3, and the object to be drilled rests on
the face-plate v or on the support v. The object to be drilled is secured, and the
-drill-spindle makes the main (rotary) as well as the feeding (longitudinal) motion.

page_text: In order to enable exact drilling to be done in a horizontal direction, the first
hing to do is, to turn the disc p on the casing through an angle of 90 and to secure
t in this position by pins q and by tightening the bolts pl.
The object to be operated upon is secured on the face-plate or on the
support v, and thus either the drill spindle (or its extension) which may be guided
if desired on a suitable guide at the back, may make both the main and the feeding
movement, or the drill spindle only makes the main movement, the feeding motion
being given to the object together with the support.
When used as a slot-drilling machine, for instance for making grooves for
keys in shafts, the turning spindle is again placed vertically, and the object to
be operated upon is secured on the support v. The rotating spindle makes there-
fore in this case the main (rotary) movement and also the vertical feeding motion
to advance the length of one cut, the horizontal feeding motion being made by the
part operated upon.
If the machine is to be used as a lathe, then the spindle is arranged horizontally
and after the tool has been removed from the drill-spindle, the face-plate is
secured on to the latter and the work is fixed to this face-plate. The tool is fixed
in a tool-holder R (Figs. 4, 5, 6) secured to the support and makes the feed motion,
the work making the main rotating movement. The work, however, may also have
a feeding motion as well, if it has a cylindrical surface.
If it is desired to use the turning device as a milling machine, the face-plate
is removed from the drill-spindle, the latter is provided with a shaft to receive
the milling cutter or is replaced by a suitable milling cutter. The work is
fixed on the support v, or if the cutter-spindle is to have a feeding (longitudinal)
motion, instead of the work, then the latter is fixed on the table . This operation
can be effected with very great advantage on the machine according to the present
invention, as only one setting or adjustment of the work is required, even if the
latter is to be cut on different surfaces. If fixed on the support the work. ;may
have the feeding motion and the cutter the main (rotary) motion.
If the machine is to be used as a slotting machine, then the planing tool is
vertical and has the main (reciprocating) motion, the work fixed on the support
making the feeding motion.
When used as a shaping machine, the cutter u is placed in the tool-holder U¹,
and its discr is turned through an angle of 90°. The work is fixed to the support v
and performs the feeding motion, the main motion being communicated to the
tool.
The work can therefore be done much quicker as it is very easy by simply
turning the arms on the main column a to bring the work, once properly set,
from the turning device under the planing device, or vice versa, or to perform
both operations simultaneously.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
1. A universal machine tool in which a main shaft operates a planing tool
and a rotatory tool, the planes in which these tools work being adjustable relatively
to the machine, for the purpose of enabling all kinds of work requiring a recipro-
cating motion of the tool as in planing or slotting, or a rotary motion of the
tool or work, as in drilling, turning and milling, to be executed with the same
planing and rotatory device substantially as described.
2. In a machine of the character described for the purpose of enabling the
tool-holder to be placed in different positions, the arrangement of discs as pr,
connected with corresponding tool-holders, said discs being secured to the discs h h¹
of the machine frame c by bolts 23, the heads of said bolts engaging with circular
grooves in the discs hh substantially as described.
5 3. In a machine of the character described, the combination of two tool-
holders U. U placed at right angles to each other, for the purpose of enabling the

page_text: planing device to be used as a slotting as well as a shaping machine substantially
as described.
4. In a machine of the character described, for the purpose of enabling both
the reciprocating and the rotating tools to be used together or separately, the
arrangement of bevel-wheels m¹ m² mounted loosely on spindles and engaging.
with a bevel-wheel on the main shaft, whereby the rotary motion of the shaft is
transmitted to the spindle of the respective tool-holders and the tools become.
operated only when said wheels m¹ m² are coupled with their respective, spindles,
substantially as described.
5. The combination and arrangement of parts constituting the complete machine
for turning, drilling, boring milling, planing or shaping, substantially as described
and illustrated in the accompanying drawings.
