Improvements in Machines for Cutting Clay in the Manufacture of
Bricks and Tiles and for like Purposes.
I CARL ALBERT EISSNER of Lugau in Saxony Empire of Germany Manufacturer
do hereby declare the nature of this invention to be as follows:-
This invention relates to the cutting into equal or predetermined lengths such
material as clay fed from a brick press and other material fed continuously with equable
or varying velocity.
The improvements consist firstly in the manner of and direct means for actuating
the cutters; secondly in the mechanism or gear by which the movement of the material
sets the actuating mechanism in motion so that the cutting of the material is rendered
dependent on the feed movement thereof.
I cause the advancing blank to rotate by friction of surface a drum or drums of
convenient shape and cause said drum or drums to revolve through suitable gear a
series of tumblers so that the latter open at predetermined intervals the inlet and outlet
ports of a cylinder whereby steam is admitted at the one or other end thereof and the
piston is driven intermittently back and forth. The piston rod carries or operates a
bow to which wires or blades are fixed and the movement of the piston causes the wires
or blades to traverse the blank in alternate direction.
The cutting of the blank into equal or predetermined parts is thus rendered inde-
pendent of the velocity of the movement of the blank.

I CARL ALBERT EISSNER of Lugau in the Kingdom of Saxony, 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:-
This invention relates to the cutting into equal or predetermined lengths such
material as clay fed from a brick press and other material fed continuously with
equable or varying velocity.
The improvements consist firstly in the manner of and direct means for actuating
the cutters secondly in the mechanism or gear by which the movement of the material
sets the actuating mechanism in motion so that the cutting of the material is rendered
dependent on the feed movement thereof.
I cause the advancing blank to rotate by friction of surface a drum or drums of
convenient shape and cause said drum or drums to revolve, through suitable gear, a
series of tumblers so that the latter open at predetermined intervals the inlet and outlet
ports of a cylinder whereby steam is admitted at the one or other end thereof and
the piston is driven intermittently back and forth. The piston rod carries or operates
a bow to which wires or blades are fixed and the movement of the piston causes
the wires or blades to traverse the blank in alternate direction.
The cutting of the blank into equal or predetermined parts is thus rendered inde-
pendent of the velocity of the movement of the blank.
Referring to the accompanying drawings illustrating the invention as applied to
the cutting of oblong and circular sections,
Fig. 1 shows the material A issuing from the tube C of the brick press.
Fig. 2 shows in side elevation the cutters and mechanism for operating them.
Fig. 3 is a plan view of said cutters and mechanism.
Figs. 4, 5 and 6 show different contrivances to be operated by friction of surface
of the clay for the setting in action at certain intervals of the mechanism con-
trolling the cutters.
Fig. 7 is an enlarged elevational view of one of the piston valves.
The cutters consist of wires or double edged knives and there may be one or
more cutters. The said cutters are fixed between the arms of a bow frame k having
a downward extension pivoted on a rocking shaft or pin. The depth of said bow frame
being sufficient to permit of free passage of the material (hereinafter called the
"blank") through the bow. The bow is connected directly or indirectly to the piston
rod qu, the piston being movable-by-steam- pressure back and forth-in-the-cylinder Z.
The stroke of the piston is sufficient to move the cutters through the blank alternately
back and forth.

page_text: A drum b or pair of drums having a shape of periphery (as g. h. ) according to the shape
of section of the blank to be cut are carried upon shafts journalled so that the super-
ficial friction of the drum or drums on the advancing blank causes the rotation of the
drums. On the shaft of one of the drums is a nitre wheel m gearing into a similar
mitre wheel m¹ on the shaft m³. On the shaft m² are fixed two tumblers o o' adapted,
as the shaft rotates, to rise under and lift levers or arms connected with the steam
inlet and outlet ports p and f respectively in connection with one end of the cylinder
aforesaid. The shaft m³ is geared with the shaft m² and carries likewise similar
tumblers oo adapted to raise levers connected with the inlet and outlet valves p' f¹
of the other end of the cylinder. The tumblers o o¹ o² o³ are so arranged that when
the inlet valve is open at one end, the outlet valve is open at the other end. It will
be seen therefore that since the feed motion of the blank controls the operation of
the cutters the blank is cut into equal or predetermined lengths without necessitating
steady feed of the blank.

It is therefore of great advantage with hand presses.
The diameter of the friction
drums determine the length of the blank cut at each passage or if more than one
cutter be fixed in the bow the aggregate length of the sections cut off at each passage
of the cutter.
The blank is supported by rollers so arranged as to permit of the passage of
the cutters between them.
The cutter operating machinery may likewise be set in action by mechanism con-
trolled by a block or other object carried forward with or by the advancing blank.
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
In machinery for cutting the clay blank from a brick press and like matters
1. The combination of a cut
adapted to be operated by th
cutter at predetermined int
lerated by independent force with mechanism
motion of the blank for setting in action said
2. The combination of à cutter, a cylinder valves thereto and a piston therein
adapted to operate said cutter and gear adapted to be operated by feed of the blank
said gear adapted to control said valves for periodical operation of said cutter sub-
stantially as set forth.
3. The combination of a cutter, a cylinder, valves thereto and a piston therein adapted
to operate said cutter, a friction drum adapted to be revolved by feed of the blank and
gear connecting said drum and valves for periodical operation of said valves sub-
stantially as and for the purpose set forth.
4. The combination with a bow carrying cutters of a cylinder having inlet
valves ppl and outlet valves fa piston in said cylinder having rod q u adapted to
move said said bow k back and forth friction drum b and tumblers o of 02 0³ revolved
by gear from said drum for the purpose set forth.
