I GEORGE JAMES HILL of Wainwright Street Ardwick near Manchester in the
County of Lançaster Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CUTTING AND SAWING CLOTH
WOOD METAL AND OTHER MATERIALS to be as follows:-
My invention consists in an improved arrangement -and construction of machine
or apparatus for cutting or sawing cloth wood metal and other materials.
In carrying my invention into effect I employ a blade or knife to which blade
or knife I impart a reciprocating motion by means of a crank or other similar
apparatus One end of the blade or knife before mentioned is jointed to one end
of a lever the opposite end of which lever is connected to a fixed framework by
means of a stud or pivot-To the knife or blade above referred to I connect one
end of a connecting rod the other end of which connecting rod embraces the pin of
a crank or such connecting rod may be connected to an eccentric-The remaining
end of the knife or blade aforesaid I provide with a projecting pin or stud which is
embraced by a slot or groove formed within an arm jointed to the fixed framework
of the machine-I also provide a table or support upon which the article to be cut
or sawn is supported and through a slit or opening in which table or support the
knife or blade above referred to passes.
The rotation of the crank or eccentric above mentioned will by means of the
connecting rod previously referred to cause the blade or knife above mentioned to
be reciprocated and the joint action of the arm above referred to, to which one end
of the said knife or blade is jointed and that of the slot previously mentioned will
when the blade or knife before mentioned is moving in one direction cause the
said blade or knife to advance and cut the material to be operated upon and upon
the blade or knife aforesaid being moved in a direction opposite to that above
mentioned will cause the said blade or knife to be withdrawn from the material to
be operated upon.
By placing the slot above mentioned more or less inclined to the length of the
blade or knife before referred to the amount of material cut by each stroke of the
said blade or knife will be varied.

page_text: In some cases I cause the above mentioned blade or knife to actuate by means
of a pawl or other suitable apparatus any suitable feed motion for feeding or
advancing the material to the action of the blade or knife before referred to or
such feed motion may be actuated by any other convenient and suitable means.
In some cases I employ a lever jointed at one end to the blade or knife before
referred to and jointed at its other end to the framework of the machine, or any
other suitable apparatus instead of the slot previously mentioned.
Although I have referred to the use of a blade or knife I in some cases propose
to employ a saw or other similar toothed blade in place of the blade or knife
above referred to.
In some cases I employ the reciprocating blade or knife in conjunction with a
fixed blade and cause the material operated upon to be cut by a shearing action.

I GEORGE JAMES HILL of Wainwright Street Ardwick near Manchester in the
County of Lancaster Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CUTTING AND SAWING CLOTH
WOOD METAL AND OTHER MATERIALS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention consists in an improved arrangement and construction of machine
or apparatus for cutting or sawing cloth wood metal and other materials.
In carrying out my invention I employ a blade or knife to which blade or knife
I impart a reciprocating motion by means of a crank or other similar apparatus.
One end of the blade or knife before mentioned is jointed to one end of a lever
the other end of which lever is connected to a fixed framework by means of a stud
or pivot. To this knife or blade I connect one end of a connecting rod the other
end of which connecting rod embraces the pin of a crank or such connecting rod
may be connected to an eccentric. The other end of the knife or blade aforesaid
I provide with a projecting pin or stud which pin or stud is embraced by a slot or
groove formed within an arm jointed to the fixed framework of the machine
I also provide a table or support upon which the article to be cut or sawn is
supported and through a slit or opening in which table or support the knife or
blade above refered to passes.
The rotation of the crank above mentioned will by means of the connecting rod
previously refered to cause the said knife or blade to be reciprocated and the joint.
action of the lever before mentioned to which one end of the said knife or blade is
jointed and that of the slot before mentioned will when the said blade or knife is
moving in one direction cause the said blade or knife to advance and cut the
material to be operated upon and upon the blade or knife aforesaid being moved
in a direction opposite to that above mentioned will cause the said blade or knife.
to be withdrawn from the material being operated upon. By placing the slot
herein before mentioned more or less inclined to the length of the said blade or
knife the amount of material cut by each stroke of the said blade or knife will be.
varied.
In some cases I cause the above mentioned blade or knife to actuate, (by means
of an eccentric or other suitable apparatus) any suitable feed motion for feeding or
advancing the material to the action of the blade or knife before refered to, or such
feed motion may be actuated by any other suitable means.
I sometimes employ a lever jointed at one end to the blade or knife hereinbefore
mentioned and jointed at its other end to the framework of the machine, or any
other suitable apparatus, instead of the slot previously mentioned.
And in order that this my said invention may be the more readily understood
and carried into practical effect I have hereunto annexed a sheet of drawings
illustrative of the same and which I will now proceed to describe with the
assistance of the Figures and letters of reference marked thereon similar letters of
reference being used to denote like parts in both views.

page_text: Fig. 1, is a side view with part of the framework removed and fig. 2, is a plan
of my improved apparatus for cutting or sawing cloth wood metal and other
materials.
A is the knife or blade to which I impart a reciprocating motion by means of
the crank B. One end of this blade or knife A is jointed to one end of a lever C
the other end of which lever C is connected to a fixed framework D by means of a
stud or pivot a To this blade or knife A. I attach one end of a connecting rod E
the other end of which connecting rod E embraces the pin b of the crank B, the
other end of the blade or knife A. I provide with a projecting pin or stud c which
pin or stud c is embraced by a slot or groove d formed within an arm G jointed to
the fixed framework D of the machine. H is a table upon which the article to be
cut or sawn is supported and through a slit or opening e in this table H the blade
or knife A passes.
Rotation which is given to the crank B by means of the shaft f and pullies g
will by means of the connecting rod E cause the blade or knife to be reciprocated
and the joint action of the lever C to which one end of the blade or knife A is
jointed and that of the slot d will when the shaft f is driven in the direction of
the arrow cause the said blade or knife A to advance and cut the material to be
operated upon, and upon the shaft f being further revolved in the direction of the
arrow the blade or knife A will be withdrawn from the material By placing the
slot or groove & more or less inclined to the length of the blade or knife A (which
may be done by the lever I this lever I being provided with notches h to catch
into the framework D to bind the slot or groove d in the position required) the
amount of material cut by each stroke of the blade or knife A can be varied. The
double lever N in conjunction with the spring O is used to keep the blade or
knife A rigid. J is a feed motion for feeding the cloth or other material being
operated upon to the knife or blade A such feed motion J being worked by the
eccentric K and crank L through the rocking shaft M.
Although I have refered to the use of and illustrated on the accompanying
drawing a blade or knife I sometimes employ a saw or other similar toothed blade
in place of the blade or knife A and in some cases I employ the reciprocating blade
or knife A in conjunction with a fixed blade and cause the material operated upon
to be cut by a shearing action. It will be obvious that the machine or apparatus
may be driven by band or foot although only illustrated as being driven by power.
Having thus particularly described and ascertained the nature of this my said
invention together with the best method with which I am acquainted for carrying
the same into practical effect I wish it to be understood that I do not confine
myself to the precise details relative proportions or dimensions of the apparatus
herein before described and illustrated on the accompanying drawing as the same
may be considerably varied without departing from my invention but what
I claim is
Firstly. The use and application of a blade or knife mounted and actuated as
and for the purposes herein before described and illustrated on the accompanying
drawing.
Secondly. The combination and arrangement of mechanism for cutting and
sawing cloth wood metal and other materials herein before described and illustrated
on the accompanying drawing.
