An Improved Machine for Cutting and Punching Metal.
I, JULIUS HERMAN SANDERS, Blacksmith, and FRANK P. EWING, Merchant, both of
Lone Elm, Anderson County, Kansas State, United States of America, do hereby
declare the nature of this invention to be as follows:-
This our invention relates to improvements in machines for punching and cutting
metal; and it consists in certain novel features hereinafter described.
In carrying out our invention we employ a base, and on the said base near one edge of
the same we erect standards, between which, at the near and upper ends of the same, we
journal two cog-wheels, and the shaft of the lower cog-wheel is projected through one
of the standards, and is provided with an operating-lever. The operating-lever,
however, may be readily dispensed with and the machine driven by a steam-engine or
other suitable motor. On the upper side of the base we provide side bars, one of
which is provided in its inner side, near its upper edge and near its rear end, with a
recess, in which we secure a knife-blade. The other side bar is provided with a
forwardly-extending arm having a hollow offset at its front end, in which the stock
or die-carrier is mounted. The side bars are provided at about their centres with
lugs, to which an oscillating bar is pivoted. This bar is provided at its rear end with a
blade, and the die-carrier is connected to the front end of the said bar by suitable links.
This die is secured in the die-carrier by means of a set-screw, mounted in the side
of the die-carrier and adapted to bind against the die after it has been fitted in a recess
in the lower end of the carrier. The die-plate is secured between the front ends of
one side har, and suitable cross-bars, extending between the bars by means of the set-
screws, mounted in the said bars.
The oscillating bar is provided in its sides, and about its centre, with grooves or
recesses, in which we secure the lower ends of suitable levers, and between the upper
ends of said levers we pivot a pitman, the front end of which is bifurcated and pivoted
to the upper gear-wheel. When it is desired to apply the greater power to the shears,
the pivot of the pitman is arranged above the shaft or fulcrum of the gear-wheel, and
when it is desired to apply the greater power to the punch the pivot is arranged below
the said shaft.
From the foregoing description it will be understood that we have provided a very
simple and compactly-arranged machine, in which the several parts are so connected as
to be easily operated, and its advantages are thought to be obvious. When it is desired
to cut the metal, the metal is inserted between the rear ends of the side bar and the
oscillating bar, and the operating-lever then vibrated so as to cause the oscillating bar
to swing in the proper direction to bring the rear end of said bar down on to the
metal, thereby cutting the same. When it is desired to punch metal, the machine is
operated so as to bring the front end of the oscillating har downward. The arrange-
ment of parts is such that a powerful force is exerted on the metal with the expenditure
of comparatively little labour. The gear-wheels multiply the power exerted thereon,
and this power is transmitted through the pitman, and the levers directly to the
oscillating bar. The punch is guided in the true vertical line by the hollow offset,
and the oscillating bar is prevented from having any lateral movement by the lugs on
the side bars. The levers being secured in grooves in the oscillating bar, will vibrate
the said bar positively and will not produce any lost motion.

An Improved Machine for Cutting and Punching Metal.
We, JULIUS HERMAN SANDERS, Blacksmith, and FRANK P. EWING, Merchant, both
of Lone Elm, Anderson County, State of Kansas, United States of America, 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 our invention relates to improvements in machines for punching and cutting
metal; and it consists in certain novel features hereinafter described and claimed.
In the accompanying drawings,
Figure 1 is a side view showing the punch raised.
Figure 2 is a similar view showing the punch lowered, with a part broken away.
Figure 3 is a horizontal section on the line, Figure 1.
Figure 4 is a detail vertical section on the line y y, Figure 2.
In carrying out our invention we employ a base, A, and on the said base near one edge
of the same we erect the standards B B, between which, at and near the upper ends
of the same, we journal two cog-wheels (C, and the shaft of the lower cog-wheel is
projected through one of the standards B, and is provided with an operating-lever D,
as shown. The operating-lever, however, may be readily dispensed with and the
machine driven by a steam-engine or other suitable motor. On the upper side of the
base we provide the side bars EE, one of which is provided in its inner side, near its
upper edge and near its rear end, with a recess F, in which we secure a knife-blade G,
as shown. The other side bar E is provided with a forwardly-extending arm H,
having a hollow offset L at its front end, in which the stock or die-carrier J is mounted.
The side bars are provided at about their centres with the lugs K, to which the
oscillating bar L is pivoted. This bar L is provided at its rear end with a blade M,
and the die-carrier J is connected to the front end of the said bar by the links N, as
clearly shown. The die is secured in the die-carrier by means of a set-screw O,
mounted in the side of the die-carrier and adapted to bind against the die after it has
been fitted in the recess P in the lower end of the carrier. The die-plate is secured
between the front ends of the side bar E and the cross bars Q, extending between the
bars E by means of the set-screws R, mounted in the said bars E and Q, as shown, and
as will be readily understood.
The oscillating bar L is provided in its sides at about its centre, with the grooves
or recesses S, in which we secure the lower ends of the levers T, and between the
upper ends of said levers is pivoted a pitman U, the front end of which is bifurcated
and pivoted to the upper gear-wheel C. When it is desired to apply the greater
power to the shears, the pivot of the pitman is arranged above the shaft or fulcrum of
the gear-wheel and when it is desired to apply the greater power to the punch the
pivot is arranged below said shaft.
From the foregoing description taken in connection with the accompanying drawings,
it will be seen that we have provided a very simple and compactly-arranged machine,
in which the several parts are so connected as to be easily operated, and its advantages
are thought to be obvious. When it is desired to cut the metal, the metal is inserted
between the rear ends of the side bar and the oscillating bar, and the operating lever
then vibrated so as to cause the oscillating bar to swing in the proper direction to
bring the rear end of said bar down on to the metal, thereby cutting the same, as will
be readily understood upon reference to the drawings. When it is desired to punch
metal, the machine is operated so as to bring the front end of the oscillating bar
downward. The arrangement of parts is such that a powerful force is exerted on the
metal with the expenditure of comparatively little labour. The gear-wheels multiply
the power exerted thereon, and this power is transmitted through the pitman U and
the levers T directly to the oscillating bar. The punch is guided in a true vertical
line by the hollow offset I, and the oscillating bar is prevented from having any lateral
movement by the lugs on the side bars. The levers T being secured in the grooves in

page_text: the oscillating bar, will vibrate the said bar positively and will not produce any lost
motion.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. The combination of the side bars, the oscillating bar pivoted between the same
and provided with grooves in its sides, the levers having their lower ends secured in
said grooves, the cog-wheels, the pitman having its rear end pivoted between the ends
of the levers and its front end pivoted to one of the cog-wheels, and means for
operating the said wheels, as set forth.
2. The combination of the side bars, one of which is provided with a knife at its
rear end and the other one having a hollow offset at its front end, the oscillating bar
pivoted between the said side bars and having a knife at its rear end, the die-carrier
connected to the front end of the oscillating bar and playing in the hollow offset of
the side bar, and mechanism for operating the oscillating bar, as set forth.
