PROVISIONAL SPECIFICATION.
An Improved Apparatus or Tool for Cutting Axle Trees, Iron Bars
and the like.
I, JÖRGEN CHRISTIAN THYGESEN, of 40, Mejlgade Aarhus, in the Kingdo
of Denmark, Mechanical Engineer, do hereby declare the nature of this inven
tion to be as follows:-
This invention relates to an improved apparatus or tool for cutting axle trees
or iron or other bars which can be arranged to be operated by hand or by
machine power and in which a knife is arranged in a sleeve, whose sharp edge
is guided round the axle or bar to be cut, the knife being at the same time
gradually forced against the axle or bar by a spring or screw arranged in the
sleeve (the knife holder) thus cutting the same.
In the annexed drawing Figs. 1-3 illustrate the apparatus in the form of
construction for hand operation and Figs. 4 and 5 show the construction when
actuated by machinery.
Fig. 1 is a front view of the hand operated apparatus.

The apparatus (Fig. 1-3) consists of a three branched steel piece a having
a cylindrical boring 6 in the centre.
wherein the steel pieces or cheeks c can be adjusted. The cheeks end in round
In each of these branches is a radial slot
bolts d which can be turned in holes of a suitable size in the steel piece a.
The cheeks can be adjusted simultaneously by means of the circular adjusting
lisk e arranged behind the steel piece a wherein three eccentric slots or guides f
re arranged in which the adjusting screws g screwed into the cheeks are
uided. When the adjusting screws are loosened the cheeks can
wards the in or the outside by turning the disk e in the one or the other
rection so that a round iron bar put through the hole in the steel piece a
be moved
n be adjusted centrally. Fixed to the steel piece is a sleeve h carrying a
el bar so that this bar which carries the knife can be moved backwards
forwards in the sleeve h. The boring of the sleeve is such that the centre
e of the steel rod is in alignment with the axis of the cylindrical boring b.
In the front end of the steel bar is a slot for receiving the disk like

toward the knife disk, which can be introduced into one of the holes p arranged
along the circumference of the disk. By turning the screw m the knife disk
is moved found its centre point so that its cutting edge is turned toward the
one or the other side.
The outer end of the sleeve his interiorly of larger diameter and threaded
so that thereinto a socket or tube 7 can be screwed serving as a shank, a spiral
spring is arranged therein whose foremost end pushes against the steel rod i.
At the other end of the spring a buffer s is arranged in contact with a screw t
in the closed end of the socket by means of which the tension of the spring can
be altered.
On the tube q a ring or sleeve u is arranged wherein an angular groove v is
cut. A handle w attached to the steel rod i passes through a slot of the tube
and through the groove of the sleeve u. If the handle is entirely moved
back in the groove v, the sleeve u can be turned so that the handle enters into
the cross part of the groove (Fig. 1). By this means the rod i with the knife
is held in such a position that the cutting edge does not come inside the direc-
tion of the boring b.
If a shaft, an axle tree or a piece of round iron or the like is to be cut, it is
fastened in a vice and introduced through the hole b in the steel piece a; then
it is centred in the hole by adjusting the cheeks c.
The cheeks are adjusted so
that the apparatus can easily move round the bar or axle tree. The sleeve u
is turned so that the handle to comes out of the cross part of the groove where-
upon the spring r pushes the knife against the bar or axle tree lying in the
hole b. The apparatus is then turned round the bar and at each turn of the
knife the bar is cut.
The steel piece a can be arranged on the end of a socket arranged movably
in two bearings lying in the prolongation of the vice wherein the bar to be
cut is engaged.
Upon the sleeve ha conical toothed wheel is in this case arranged gearing
with another conical toothed wheel arranged rectangularly to the axle and
which can be turned by means of a hand crank or a pulley so that thereby the
axle can be cut.
Figs. 4 and 5 represent the apparatus arranged for being actuated by machine
power. The parts of the apparatus are the same as described hereinbefore and
are marked with the same reference letters.
A bedding x has bearings for a cast socket y whose one end is formed as a
pulley z whilst its other end carries the piece h receiving the steel bar i with
the knife disk j and the herebefore described pieces for their adjustment. The
rod is in this case not pushed forward by a spiral spring but is gradually
moved forward by a screw 1 screwed into an axial boring in the rod . The
screw can be rotated in the piece but not moved forward therein. The lower
end of the screw 1 carries a toothed wheel 2 which by the revolution of a
socket is moved for one tooth by means of a projection arranged on the
bedding. Consequently the rod i is moved by each revolution a little so that
the knife disk cuts gradually deeper into the round iron bar or other piece
introduced through the central boring 6 of the socket.
y
The round iron rod is secured in place by means of two vices 5 arranged on
the bedding arranged on each side of the socket y respectively, and each con-
sisting of two cheeks which can grasp the iron bar by means of a screw being
threaded half right half left, so that the axis of it agrees with the axis of the
socket. In the socket there is a cutting out 4 through which the iron bars
or the like to be cut can be put into the apparatus.

ICATION.
An Improved Apparatus or Tool for Cutting Axle Trees, Iron Bars,
and the like.
I, JÖRGEN CHRISTIAN THYGESEN, of 40, Mejlgade Aarhus, in the Kingdom
of Denmark, Mechanical Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly de-
scribed and ascertained in and by the following statement:-
This invention relates to an improved apparatus or tool for cutting axle trees
or iron or other bars which can be arranged to be operated by hand or by
machine power and in which a knife is arranged in a sleeve whose sharp edge
is guided round the axle or bar to be cut, the knife being at the same time
gradually forced against the axle or bar by a spring or screw arranged in the
0 sleeve (the knife holder) thus cutting the same.
In the drawing filed with my Provisional Specification Figs. 1-3 illustrate
the apparatus in the form of construction for hand operation and Figs. 4 and 5
show the construction when actuated by machinery.
Fig. I is a front view of the hand operated apparatus.
Fig. 2 a longitudinal section through the centre of the apparatus.
Fig. 3 represents the fore part of the apparatus from the back.
Fig. 4 is a vertical section through the centre of the apparatus arranged for
machine
power.
Fig. 5 is a section on the line A-B of Fig. 4 seen in the direction of the
arrow.
ll.
The apparatus (Fig. 1-3) consists of a three-branched steel piece a. having
a cylindrical boring 6 in the centre. In each of these branches is a radial slot
wherein the steel pieces or cheeks c can be adjusted. The cheeks end in round
bolts which can be turned in holes of a suitable size in the steel piece
The cheeks can be adjusted simultaneously by means of the circular adjusting
disk e arranged behind the steel piece wherein three eccentric slots or guides f
are arranged in which the adjusting screws y screwed into the cheeks are
guided. When the adjusting screws
owards the in or the outside by turning the disk e in the one or the other
are loosened the cheeks can be moved
irection so that a round iron bar put through the hole 6 in the steel piece a
an be adjusted centrally. Fixed to the steel piece a is a sleeve h carrying a
teel bar so that this bar which carries the knife can be moved backwards
forwards in the sleeve h. The boring of the sleeve is such that the centre
ne of the steel rod is in alignment with the axis of the cylindrical boring b.
In the front end of the steel bar is a slot for receiving the disk like
ife j; the knife is held fast by means of a screw k going through the centre
the knife. In the knife is a sector shaped cutting out of 90° whose one
ter edge suitably curved forms the blade. This blade can be adjusted so
at it lies in the direction of the boring in the longitudinal plane of the
paratus.
The adjusting is effected by an adjusting screw
; the lower end of the screw m is influenced by a trigger whose one end
m screwed into the steel
ed through the screw k. The other end of the trigger carries a bolt o turned
ard the knife disk, which can be introduced into one of the holes
g the circumference of the disc. By turning the screw m the knife disc
hoved round its centre point so that its cutting edge 7 is turned toward the
» arranged
or the other side.
he outer end of the sleeve his interiorly of larger diameter and threaded

page_text: so that thereinto a socket or tube q can be screwed serving as a shank, a spiral
spring is arranged therein whose foremost end pushes against the steel rod i
At the other end of the spring a buffer s is arranged in contact with a screw t
in the closed end of the socket by means of which the tension of the spring can
be altered.
On the tube a ring or sleeve u is arranged wherein an angular groove vis
cut. A handle w attached to the steel rod passes through a slot of the tube q
and through the groove of the sleeve u. If the handle w is entirely moved
back in the groove the sleeve u can be turned so that the handle enters into
the cross part of the groove (Fig. 1). By this means the rod i with the knife
is held in such a position that the cutting edge does not come inside the direc-
tion of the boring b.
If a shaft, an axle tree or a piece of round iron or the like is to be cut, it is
fastened in a vice and introduced through the hole 6 in the steel piece a; then
it is centred in the hole by adjusting the cheeks c. The cheeks are adjusted so
that the apparatus can easily move round the bar or axle tree. The sleeve
is turned so that the handle w comes out of the cross part of the groove where-
upon the spring r pushes the knife against the bar or axle tree lying in the
hole b. The apparatus is then turned round the bar and at each turn of the
knife the bar is cut.
The steel piece « can be arranged on the end of a socket arranged movably
in two bearings lying in the prolongation of the vice wherein the bar to be
cut is engaged.
Upon the sleeve a conical toothed wheel is in this case arranged gearing
with another conical toothed wheel arranged rectangularly to the axle and
which can be turned by means of a hand crank or a pulley so that thereby the
axle can be cut.
Figs. 4 and 5 represent the apparatus arranged for being actuated by machine
power. The parts of the apparatus are the same as described herein before and
are marked with the same reference letters.
A bedding has bearings for a cast socket y whose one end is formed as a
pulley whilst its other end carries the piece h receiving the steel bar i with
the knife disk and the herein before described pieces for their adjustment. The
rod is in this case not pushed forward by a spiral spring but is gradually
moved forward by a screw 1 screwed into an axial boring in the rod i. The
screw can be rotated in the piece h but not moved forward therein. The lower
end of the screw 1 carries a toothed wheel 2 which by the revolution of a
socket y is moved for one tooth by means of a projection 3 arranged on the
bedding. Consequently the rod i is moved by each revolution a little so that
the knife disk cuts gradually deeper into the round iron bar or other piece
introduced through the central boring 6 of the socket.
The round iron rod is secured in place by means of two vices 5 arranged on
the bedding arranged on each side of the socket y respectively, and each con-
sisting of two cheeks which can grasp the iron bar by means of a screw being
threaded half right half left, so that the axis of it agrees with the axis of the
socket. In the socket there is a cutting out 4 through which the iron bars
or the like to be cut can be put into the apparatus.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. An improved tool or apparatus for cutting shafts, axles, round iron bars,
or the like, by means of a knife, provided in a knife holder, whose cutting edge
is led round the object to be cut, the edge of the knife being forced against the
latter by a spring bearing against the back end of the knife holder or by means
of a movable threaded shaft which moves the knife forward by degrees.
2. A form of construction of the apparatus described in Claim 1 having a

page_text: adjusted by means of an adjusting disk e provided with eccentric slots and in
with centering cheeks which can be simultaneously
which the knife disc j is arranged adjustably in a knife holder which can be
moved in a sleeve h and is influenced by a spring arranged in the handle of
the apparatus whose tension can be altered by means of a screw t (Figs. 1-3).
3. A form of construction of the apparatus described in Claim I in which
a socket y joined to a pulley carries also a piece h receiving the knife holder,
movable in the same by means of a screw 1 which carries below a ratchet
wheel 2, which at each complete revolution of the socket y is moved for one
tooth by a projection 3 seated on the bedding of the apparatus so that the
knife holder i is moved forward by degrees.
