Bread, and other Materials.
A communication from HOFFNUNG & COMPANY, of Pitt Street, Sydney, in the
Colony of New South Wales.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be
as follows:-
This invention relates to cutting devices applicable to various purposes but
particularly suitable for cutting tobacco and it is herein described in that
application.
The portion into which the tobacco to be cut is placed which is called the
receiver is preferably of a flat box-like form the lid of which may be hinged or
pivotted so that it can be raised up or closed and secured by a turn button or
other device; or if preferred the receiver may be made as a casing with some
of the ends or sides open the tobacco in that case being fed in at one end or side
and passing out at the other.
The cover or lid of the receiver is preferably provided with a spring guard or
shield which in the case of cake tobacco would accommodate cakes of various
thickness or should the tobacco be in a loose form it will compress and hold it
so that it can be conveniently cut.
The wall of the receiver furthest from the knife is made movable and caused
to travel forwards for feeding purposes in the following manner. The wall is
provided with an arm or extension bearing a portion of a screw-thread with
which engages a suitable worm rotated slowly by suitable means say for example
a pawl or ratchet mechanism operated by or in conjunction with the knife or
cutting lever. By this means between the cuts the wall and consequently the
tobacco is fed forward to a suitable extent. Arrangements may be made for
varying the feed if required.
The cutting device may be of any suitable construction a simple knife secured
upon a hand lever is suitable; the lever may be pivotted upon the ratchet or
bolt which forms the hinge of the lid of the receiver so that the one bolt will
carry the knife and its lever, the lid of the receiver and the lever or equivalent
which operates the ratchet mechanism. The worm previously mentioned may
be carried upon a stud upon the lid so that when the latter is open the worm
is moved out of engagement with the arm of the arm of the movable wall and
generally out of the way.
A tray or any convenient form of delivery shoot or receptacle may be used.
The shape and dimensions of the machine above described may be varied
according to the material it is to work upon; for example if used for bread cut-
ting the size of the various parts and particularly the receiver may be accordingly
varied.

page_text: A rotary or reciprocating, knife may be employed instead of the one previously
described if preferred.
Any suitable materials may be employed in the machine.

Improvements in or relating to Cutting Machines for Tobacco,
Bread, and other Materials.
A communication from HOFFNUNG & COMPANY, of Pitt Street, Sydney, in the
Colony of New South Wales.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, 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 cutting devices applicable to various purposes but
particularly suitable for cutting tobacco and it is herein described in that
application.
The portion into which the tobacco to be cut is placed which is called the
receiver is preferably of a flat box-like form the lid of which may be hinged or
pivotted so that it can be raised up or closed and secured by a turn button or
other device; or if preferred the receiver may be made as a casing with some
of the ends or sides open the tobacco in that case being fed in at one end or side
and passing out at the other.
The cover or lid of the receiver is preferably provided with a spring guard or
shield which in the case of cake tobacco would accommodate cakes of various
thickness or should the tobacco be in a loose form it will compress and hold it
so that it can be conveniently cut.
The wall of the receiver furthest from the knife is made movable and caused
to travel forwards for feeding purposes in the following manner. The wall is
provided with an arm or extension bearing a portion of a screw-thread with
which engages a suitable worm rotated slowly by suitable means say for example
a pawl and ratchet mechanism operated by or in conjunction with the knife or
cutting lever. By this means between the cuts the wall and consequently the
tobacco is fed forward to a suitable extent. Arrangements may be made for
varying the feed if required.
The cutting device may be of any suitable construction a simple knife secured
upon a hand lever is suitable; the lever may be pivotted upon the bracket or
bolt which forms the hinge of the lid of the receiver so that the one bolt will
carry the knife and its lever, the lid of the receiver and the lever or equivalent
which operates the ratchet mechanism. The worm previously mentioned may
be carried upon a stud upon the lid so that when the latter is open the worn
is moved out of engagement with the arm of the movable wall and generally
out of the way.
A tray or any convenient form of delivery shoot or receptacle may be used.
The shape and dimensions of the machine above described may be varied
according to the material it is to work upon; for example if used for bread cut-
ting the size of the various parts and particularly the receiver may be accordingly
varied.

page_text: A rotary or reciprocating knife may be employed instead of the one previously
described if preferred.
Any suitable materials may be employed in the machine.
In the accompanying drawings
Figure 1 is a plan of the improved cutting device.
Figure 2 is an end elevation of the same.
Figure is a section on the line 3-3 of Figure 2.
Like letters indicate like parts throughout the drawings.
Upon a suitable base A conveniently of wood is mounted a plate B upon
which are formed parallel projections B1, which constitute the sides of the casing
containing the material to be cut. The plate 13 also carries lugs B2, through
which passes a bolt C. Upon one end of this bolt is mounted a lever D which
carries a suitable knife E attached thereto by bolts E. Hinged upon the bolt C
by lugs F is a plate F which forms the lid of the casing containing the material
to be cut, and finally upon the end of the bolt C opposite to that upon which is
mounted the lever D is rigidly mounted a crank arm G. The latter is connected
by a link H with the end of a lever J pivotted upon a stud K mounted upon the
lid of the casing. The stud K also carries loose upon it a worm wheel L to
which is rigidly connected a ratchet wheel L. The lever J carries a spring
controlled pawl J, which engages with the ratchet wheel L' so that the latter
and consequently the worm wheel L can be rotated by the movement of the
lever J about the stud K. This movement takes place owing to the movement of
the lever carrying the knife, which, as it is raised and lowered oscillates the
bolt Cand consequently the crank G.
The projections B on the plate B form two sides of the casing containing the
material to be cut, the third side of this casing is formed by a plate M, which
has attached to it, so as to project at right angles from its back, a rack bar Mi
which lies in a guide B³ formed on the base plate B. When the lid F of the
casing is closed and held so by the turn-button N mounted on the base B, the
worm wheel L is in engagement with the rack M when it will be seen that as
the lever carrying the knife is raised and lowered by means of the ratchet
and pawl L and J the worm L and consequently the rack M will receive an
intermittent movement which will cause the material within the casing to be
fed forward towards the knife E at each stroke of the latter.
On the inside of the casing F is mounted a spring plate F2, which serves to
compress the material as it passes to the knife. The feeding of the material
is also made by placing in front of the plate M a bar P of triangular or other
section.
A delivery shoot Q mounted upon, and if necessary projecting from, the base A
serves to contain the material after it is cut. The free end D1 of the lever D
is conveniently formed as a handle when the device is intended to be hand
operated, but it is to be understood that the device may be modified so as to
be driven by power, if desired.
By mounting the stud K upon the lid of the casing it will be seen that when
this lid is open the worm wheel L will be lifted out of engagement with the
rack M, thus leaving the latter free for readjustment when the casing is filled.
Having now particularly described and ascertained the nature of the said in-
vention as communicated to me by my foreign correspondents, and in what
manner the same is to be performed, I declare that what I claim is:-
1. In a cutting device the combination with a knife of a device operated by
the movement of the knife for feeding the material to the knife between the
strokes of the latter substantially as described.
2. In a cutting device the combination with a knife of a feeding device com-
prising a rack in engagement with a worm which is intermittently rotated by
the movement of the knife substantially as described.
3. In a cutting device a casing for the material to be cut one of the sides of

page_text: the casing being movable and so constructed that the movement of the knife
will cause intermittent movement of the side of the casing so as to feed the
material to the knife substantially as described.
4. In a cutting device the combination with a knife of a casing to contain the
materials to be cut having a hinged lid and one side movable by means of a rack
and worm intermittently rotated by the movement of the knife the worm being
carried upon the lid of the casing so that when the lid is raised the worm will
be out of engagement with the rack substantially as described.
5. The complete cutting device substantially as described or illustrated in the
accompanying drawings.
