PROVISIONAL SPECIFICATION.
Machine for Cutting Various Sections of Metal Bars, Rods, and
the like.
I, EDWIN SAGELSDORFF of 98 Dresdenerstrasse, Berlin in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The present invention relates to a machine for cutting various sections of metal
bars rods and the like.
In the ordinary machines of this kind heretofore in use the circular saw blade is
so large that the work or article to be cut becomes in consequence of the downward
movement of the support gradually acted upon in its full width in the manner
indicated by dotted lines in Fig. 2 of the accompanying drawings.
Also it is a well-known fact which will be readily understood without further
explanation that in consequence of this arrangement considerable power must be
employed for driving these machines because in such a case the friction of the saw
blade against the two sides of the saw cut in the work gradually increases as the
saw cuts more deeply in and consequently becomes at last enormous.
Now this drawback is obviated in the machine constructed according to the
present invention viz.: by employing a saw of small size that is to say of such a size
as will enable it to cut conveniently and completely through the work and by
moving said saw both in a vertical and in a horizontal direction in the plane of the
cut so that only narrow longitudinal strips of the work are cut away in succession
whereby the friction of the saw against the sides of the cut is limited to a but
slightly variable minimum corresponding to the varying width of the cut strips.
Furthermore the ordinary transverse cutting machines as at present employed
have the disadvantage of not being adapted for use for cutting articles of great length
in small workshops or confined spaces because after one end of the work has been
cut the work must be taken out of the machine and replaced in a reverse position in
order to allow of its other end being cut the reason for this being that a simple
(rectilinear) movement of the work carrier along the table of the machine is
prevented on account of the saw carriage with the shafts or axles and wheels being
in the way.
This drawback also is obviated by the present invention in a simple manner
hereinafter described. The arrangement for effecting this object also affords the
advantage that bevels of any kind can be cut in succession without the necessity of
having to adjust the work to suit the different angles of the bevels.
This is an advantage for want of which the ordinary machines are not capable of
being employed in small works.
The drawings show two constructional arrangements of this machine:-
Fig. 1 being a partial front elevation of the first arrangement.
Fig. 2 shows the same in section on the line x-y of Fig. 1.
Fig. 3 is a plan of the same.
Fig. 4 shows the second arrangement in vertical section through the rotary axis:
of the work carriage.
Fig. 5 is a diagram according to Figs. 1-3, and
Fig. 6 illustrates a detail in vertical section of the first arrangement of:

page_text: In Figs. 1 and 3 a is the driving shaft which transmits the rotary motion it
receives from the belt pulley b to the vertical shaft d by means of the bevel wheel
gearing c c. From the shaft d the motion is transmitted by means of the bevel
wheel gearing e el Fig. 6 to the short shaft f and from the latter by means of the
gearing 9 g to the shaft h which serves through the medium of the gearing i land
the gearing kk to rotate respectively the saw blade n fixed on the spindle and
the saw blade o fixed on the spindle m see Figs. 2 and 3.
The spindles and m of the two saw blades are carried in bearings or lugs cast
formed or mounted on the plates p p¹ which are adapted to pivot about the axle h
Figs. 13 and 6.
1"
The plates p p are guided on the cheeks q g' of the sliding carriage by means
of slots or ways and thumb screws extending through said slots or ways.
The sliding carriage r rests in and is capable of horizontal movement in the carrier
or support The cheeks q q' serve as bearings for the horizontal guide spindle s
and the shaft h is carried in bearings in the cheeks tt of the sliding carriage r.
The support is guided by means of slide or guide bars (of dovetail form in cross
section) along the bed u which is capable of pivotting about the shaft d (Fig. 3).
The vertical guide spindle s¹ serves for effecting the vertical movement of the
support and together with the latter of the sliding carriage r and the saw-blades n
and o.
This vertical guide spindle & is actuated by means of the hand wheel v
whilst the horizontal guide spindle s is rotated by means of the handwheels w w¹
mounted on its two ends.
As already stated the vertical bed u is adapted to rotate about the shaft d and is
formed with a circular foot plate z which rests in a suitable recess in the table A.
of the machine.
This foot-plate has an index hand or pointer which (when the bed is rotated)
moves over a scale or index 2 fixed on the table of the machine:
"Under the foot-plate the bed has a screw-threaded stud or partiu' upon which is
screwed a nut u² that is adapted to be tightened by means of a spanner. The nut u²
bears against the turned lower face of a circular projection of the table and by this
means serves to fix the bed u in the desired position for the time being.
The support B for the work rests in dovetail guides on the table A of the
machine and is adapted to be moved along the guide bars 3 and 4 by means of the
guide spindle 5 which is operated by means of crank gearing. The work 6 bears
(at one end or side thereof) against the bar 7 of the support and is held at its
other end or other part thereof by a clamp 8 which is adjustably mounted on
the support by any suitable means such as screws and angle irons.
32
The wheels e and gl are mounted on "feathers on the shafts d and
which latter
are formed respectively with longitudinal grooves or keyways d' and h¹ for this
purpose Figs. 6 and 2.
The wheel e is mounted on or connected to a grooved roller 9 and in the groove
of this latter there engages the fork 10 (see Fig. 6) which thereby carries the
wheel e along with it when the support is moved vertically. The wheel g¹ is
held on one hand by means of the wheel 9 and on the other hand by means of a
lug 11 cast on the support l see Fig. 2.
.
The mode of operation of the machine herein described is as follows:-
After the work 6 is clamped on the support B the bed u is rotated about d in
such a manner as to bring the pointer over that division mark of the scale 2 that
corresponds to the bevel to be cut and the nut u² is tightened up.
Then the support B and with it the work is moved into the desired position by
means of the spindle 5 and its gearing. Then the driving belt is guided over
from the loose pulley 6 on to the fast pulley b whereby the shaft a is caused to
rotate.. This shaft transmits its motion in the manner herein before described to the
saw blades n and o. These latter are now by suitable rotation of the handwheels v
and w moved gradually lower down and in a horizontal direction so that the cut is
made by the saw n or several such cuts as desired.
If the other end is to be sawn off or the opposite bevel is to be cut then the

page_text: nut u is slacked back the bed u (and with it the support r¹ and sliding carriage r
together with the guide spindles and saws) is rotated through 180° and then the
nut is tightened up again. The saw o is now opposite to the work and is moved
along the work by suitable rotation of the hand wheels v and w¹ in the same manner
as was done previously with the saw n. For this the work must be shifted before
making the new cut merely to such an extent in its longitudinal direction as will
just bring the place where the new cut is to be made in front of the saw o. But it
is not necessary as in the ordinary machines at present for the purpose of making
the new cut or of cutting the opposite bevel that the work should be taken out of
the machine and re-set in a reverse position or with an opposite inclination which
latter operation cannot be carried out in a narrow space such as is generally to be
found in small workshops.
If a cut is to be made at an angle with the horizontal the corresponding plate p
or pl (after slacking the thumb screw fixed on the opposite. cheek or q₁ of the
sliding carriage r) is rotated about the shaft h so that the pointer 12 or 12¹ will be
situated behind that division mark of the scale 13 or 13' which corresponds to the
desired angle the guide spindles sliding in a slot in the corresponding plate after
which the thumb-nut is again tightened so that the plate and with it the axle lor m
and the saw n or o carried by it is held fast in the proper position for making the
desired cut (see Fig. 6).
- >
In the arrangement shown in Fig. 4 the saws can only be shifted in a horizontal
direction whilst the shifting of the work in a vertical direction with reference to the
oppositely situated saw is effected by raising or depressing the table A¹ of the
machine by means of the screw-threaded spindle 14 which is rotated by means of a
handwheel 143.
:
The table is carried by the tubular framing 15 on which is cast the internally
screw-threaded nut or socket 16 in which operates the said spindle 14 and which
when the latter is rotated slides and is guided in the sleeve 17 that is cast on the
bed-plate.
Furthermore in this arrangement there is no rotation of the bed u with the
support sliding carriage and the saws but the support B' for the work (which
support is mounted on the turntable 18) is rotated according to the desired angle of
bevel to be cut.
19 is the screw-threaded pivot on which the turntable 18 turns and 20 is nut
screwed upon the same and serving to fix the work support upon the turntable at
the desired angle.
21 is the scale of the bevels, and
22 is the pointer for the same.
:
But this arrangement has the disadvantage similarly to the ordinary machines
employed at present (as compared with the first arrangement herein before
described) that in cutting different bevels in succession the work must be sét
obliquely each time according to the angle of bevel desired so that this
arrangement is therefore more suitable for. cutting work of large dimensions
in large works and for cutting smaller work in smaller workshops.

I, EDWIN SAGELSDORFF of 98 Dresdenerstrasse, Berlin, in the Empire of
Germany, Manufacturer, 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 :-
The present invention relates to a machine for cutting various sections of metal
bars rods and the like.

the advantage that bevels of any kind can be cut in succession without the
necessity of having to adjust the work to suit the different angles of the
bevels.
This is an advantage for want of which the ordinary machines are not capable
of being employed in small works.
Refering to the drawings left with the Provisional Specification herein-these
drawings show two constructional arrangements of this machine :-
Fig. i being a partial front elevation of the first arrangement.
Fig. 2 shows the same in section on the line x-y of Fig. 1.
Fig. 3 is a plan of the same.
Fig. 4 shows the second arrangement in vertical section through the rotary axis
of the work carriage.
Fig. 5 is a diagram according to Figs. 1-3, and
Fig. 6 illustrates a detail in vertical section of the first arrangement of machine.
In Figs. 1 and 3-a is the driving shaft which transmits the rotary motion it
receives from the belt pulley b to the vertical shaft d by means of the bevel wheel

page_text: gearing cc. From the shaft d the motion is transmitted by means of the bevel
wheel gearing ee Fig. 6 to the short shaft and from the latter by means of the
gearing 9 g to the shaft which serves through the medium of the gearing i i¹ and
the gearing kk' to rotate respectively the saw blade a fixed on the spindle / and
the saw blade o fixed on the spindle m see Figs. 2 and 3.
The spindles and m of the two saw blades are carried in bearings or lugs-
cast formed or mounted on the plates ppl which are adapted to pivot about the
axle Figs. 13 and 6.
The plates pp' are guided on the cheeks 9 q¹ of the sliding carriage r by
means of slots or ways and thumb screws extending through said slots or ways.
The sliding carriage r rests in and is capable of horizontal movement in the
carrier or support . The cheeks q q¹ serve as bearings for the horizontal guide
spindles and the shaft his carried in bearings in the cheeks of the sliding
carriage r. The support r¹ is guided by means of slide or guide bars (of dovetail
form in cross section) along the bed u which is capable of pivoting about the
shaft d (Fig. 3). The vertical guide spindle s¹ serves for effecting the vertical
movement of the support r¹ and together with the latter of the sliding carriage r
and the saw blades n and o. This vertical guide spindle s¹ is actuated by means of
the hand wheel whilst the horizontal guide spindle s is rotated by means of the
handwheels w w¹ mounted on its two ends.

As already stated the vertical bed u is adapted to rotate about the shaft d and is.
formed with a circular foot plate z which rests in a suitable recess in the table A
of the machine.
This foot-plate has an index hand or pointer which (when the bed is rotated).
moves over a scale or index 2 fixed on the table of the machine.
Under the foot-plate the bed has a screw-threaded stud or part u¹ upon which is
screwed a nut u that is adapted to be tightened by means of a spanner. The
nut u bears against the turned lower face of a circular projection of the table
and by this means serves to fix the bed u in the desired position for the time
being.
The support B for the work rests in dovetail guides on the table A of the
machine and is adapted to be moved along the guide bars 3 and 4 by means of the
guide spindle 5 which is operated by means of crank gearing. The work 6 bears
(at one end or side thereof) against the bar 7 of the support and is held at its
other end or other part thereof by a clamp 8 which is adjustably mounted on the
support by any suitable means such as screws and angle irons.
The wheels e and g¹ are mounted on "feathers" on the shafts d and h which
latter are formed respectively with longitudinal grooves or keyways d¹ and ¹ for
this purpose Figs. 6 and 2.
The wheel e is mounted on or connected to a grooved roller 9 and in the groove
of this latter there engages the fork 10 (see Fig. 6) which thereby carries the
wheel e along with it when the support is moved vertically. The wheel g¹ is.
held on one hand by means of the wheel g and on the other hand by means of a
lug 11 cast on the support r¹ see Fig. 2.
The mode of operation of the machine herein described is as follows:-
After the work 6 is clamped on the support B the bed u is rotated about d
in such a manner as to bring the pointer i over that division mark of the scale 2
that corresponds to the bevel to be cut and the nut u2 is tightened up.
Then the support B and with it the work is moved into the desired position by
means of the spindle 5 and its gearing. Then the driving belt is guided over from
the loose pulley ¹ on to the fast pulley b whereby the shaft a is caused to rotate.
This shaft transmits its motion in the manner hereinbefore described to the saw
blades n aid o. These latter are now by suitable rotation of the handwheels v
and w moved gradually lower down and in a horizontal direction so that the cut is
made by the saw n or several such cuts as desired.
If the other end is to be sawn off or the opposite bevel is to be cut then the
nut u³ is slacked back the bed u (and with it the support r¹ and sliding carriage.r

page_text: But it
together with the guide spindles and saws) is rotated through 180° and then the
nut u² is tightened up again. The saw o is now opposite to the work and is moved
along the work by suitable rotation of the handwheels and w¹ in the same manner
as was done previously with the saw n. For this the work must be shifted before
making the new cut merely to such an extent in its longitudinal direction as will
just bring the place where the new cut is to be made in front of the saw o.
is not necessary as in the ordinary machines at present for the purpose of making
the new cut or of cutting the opposite bevel that the work should be taken out of
the machine and re-set in a reverse position or with an opposite inclination which
latter operation cannot be carried out in a narrow space such as is generally to be
found in small workshops.
If a cut is to be made at an angle with the horizontal the corresponding
plate por p (after slacking the thumb screw fixed on the opposite cheek 9 or q
of the sliding carriage r) is rotated about the shaft h so that the pointer 12 or 12¹
will be situated behind that division mark of the scale 13 or 13' which corresponds
to the desired angle the guide spindle s sliding in a slot in the corresponding plate
after which the thumb-nut is again tightened so that the plate and with it the
axle or m and the saw n or o carried by it is held fast in the proper position for
making the desired cut (see Fig. 6).
In the arrangement, shown in Fig. 4 the saws can only be shifted in a horizontal
direction whilst the shifting of the work in a vertical direction with reference to
the oppositely situated saw is effected by raising or depressing the table A¹ of
the machine by means of the screw-threaded spindle 14 which is rotated by means
of a handwheel 14ª.
The table is carried by the tubular framing 15 on which is cast the internally
screw-threaded nut or socket 16 in which operates the said spindle 14 and which
when the latter is rotated slides and is guided in the sleeve 17 that is cast on the
bed-plate.
:
Furthermore in this arrangement there is no rotation of the bed u with the
support sliding carriage and the saws but the support B' for the work (which
support is mounted on the turntable 18) is rotated according to the desired angle
or bevel to be cut.
19 is the screw-threaded pivot on which the turntable 18 turns and 20 is nut
screwed upon the same and serving to fix the work support upon the turntable at
the desired angle.
21 is the scale of the bevels, and
22 is the pointer for the same.
But this arrangement has the disadvantage similarly to the ordinary machines
employed at present (as compared with the first arrangement hereinbefore
described) that in cutting different bevels in succession the work must be set
obliquely each time according to the angle of bevel desired so that this
arrangement is therefore more suitable for cutting work of large dimensions in
large works and for cutting smaller work in smaller workshops.
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 :-
1. The combination in a machine for cutting iron bars rods or the like of various
cross sectional forms of a saw adapted to be shifted gradually both in a vertical
and horizontal direction in such a manner that the saw will cut only narrow
longitudinal strips of the work in succession and will consequently be compelled to
follow the bends of the work substantially in the manner hereinbefore described.
2. The combination in a machine as and for the purposes claimed above of a
support (capable of vertical motion on the bed u by means of a guide spindle s¹)
in which the sliding carriage r which carries the saws n and o is mounted in such a
manner as to be horizontally movable by means of the guide spindle s substantially
in the manner and for the purposes hereinbefore set forth.

page_text: 3. A machine as and for the purposes claimed in Claim 1 having in combination
therewith a bed u of the support adapted to rotate (on the table of the machine)
about a shaft d which transmits the motion to the saws and said bed carrying a
pointer which moves over a scale 2 provided on the table of the machine
substantially in the manner and for the purposes hereinbefore set forth.
4. A machine as and for the purposes claimed in Claim 1 having the spindle /
and m of the saws n and o mounted respectively in plates p and p' said plates being
adapted to rotate about the shaft h (which transmits motion to the saw spindle)
and being provided with scale 13 and 13' respectively connected with which there
is a pointer 12 and 12¹ fixed to the cheeks q and 9 of the sliding carriage r
combined and arranged to act substantially in the manner and for the purposes
hereinbefore set forth.
5. The modified arrangement of the machine claimed in Claim 1 in which the
machine table A¹ can be raised or lowered by means of a spindle 14 and the work
support B is mounted on a turn-table 18 which is capable of rotating about a
screw-threaded stud 19 on the machine table and of being fixed in position by
means of a nut 20 all arranged combined and acting substantially in the manner
and for the purposes hereinbefore set forth.
