Year: 1872

page_text: LETTERS PATENT to William Richter, of Eintrachtshütte, Kingdom
of Prussia, Engenieur, for the Invention of "AN IMPROVED MACHINE
FOR BREAKING BAR IRON."
Scaled the 3rd September 1872, and dated the 4th July 1872.
COMPLETE SPECIFICATION filed by the said William Richter at the
Office of the Commissioners of Patents, with his Petition and Decla-
ration, on the 4th July 1872, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
RICHTER, of Eintrachtshütte, Kingdom of Prussia, Ingénieur, send
greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED
MACHINE FOR BREAKING BAR IRON," and have petitioned Her Majesty to
grant unto me, my executors, administrators, and assigns, Her Royal
Letters Patent for the same, and have made solemn Declaration that
I am the true and first Inventor thereof.

page_text: NOW KNOW YE, that I, the said William Richter, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what
manner the same is to be performed, in and by the following state-
ment, reference being had to the accompanying Drawing forming a part
of this Specification:-
Figure 1 is a plan of my improved machine, part of the same being
removed; Figure 2 is a side clevation (part in section); and Figure 3 is
an end clevation of the said machine.
The machine consists of the following principal parts :—a is a cast-
iron frame provided with bearings for the crank shaft; b, c, is a worm
wheel fastened to the end of the crank shaft b; d is a pivot, and c is a
claw working on the said pivot and provided with a set screw and
wheel. A worm shaft is provided with a strap drum g and a worm h,
which works into the worm wheel.c placed at the bottom and behind
the cast-iron frame a; on each side of the strap drum g are loose strap
drums i, i. A starting lever with a weight & fitting loosely on a pivot
on the crank shaft is moved by pivots 1, 1, in the worm wheel c. The
strap holder m is brought into connection with the starting lever k by
means of the lever o, and the arm n on the holder m and is moved back-
ward and forward by the starting lever k through the weight fixed to
the same.
A reversing shaft p carries at one extremity the hand
lever r, and is further connected with the strap holder m by means of
the lever q. A spring hooks is placed on the front of the main frame.
The machine is driven by means of a band or strap.
The peculiarities of this machine and its advantages over other
puddle bar breaking machines are,-
First. This machine will break the mill bar in any required part
without in the least degree injuring or deforming the same.
Second. The said machine stops itself as soon as it has completed its
work, that is to say, when the crank shaft has made one ascending and
descending movement it ceases to act.
Third. The bent-up end of the puddle bar is broken off and taken
back from the crank shaft through the crank pin f.
The operation of the said machine is as follows:-The bar to be
broken is pushed through under the claw e above the crank shaft b
until it comes beneath the crank pint; it is then by the regulating

page_text: wheel and screw pressed firmly upon the projection u. Then the
operator presses back the springs which holds the lever 1, the machine
is thereby released in readiness for furthur action, and the weight on
the starting lever / brings one of the straps upon the fixed driving
drum g. By the above described movements the worm shaft and the
screw wheel are driven upward until the bar by means of the crank axle
is bent, as shown in the Drawing. When this is completed the screw
wheel by means of the bolt fixed thereon has thrown or shifted the
starting lever to the other side, and the weight has drawn the strap
holder also to the other side, and thus brings the second strap upon the
driving drum g. The worm shaft now receives motion in a direction
opposite to that of its previous action and thus drives the crank shaft
downwards, the piece of bar projecting beneath the crank pin is at the
same time forced back and so broken off.
By the above described change in the working of the machine the
hand lever passes the hook spring without being caught by the same.
As soon as the crank shaft has reached its lower position as shown in
the accompanying Drawing, the starting lever is again thrown to the
opposite side by the second bolt to change the straps, through this
motion the hand lever which is in communication with the strap
holder makes an ascending movement and is thus caught by the spring
hook at the point y. The machine now ceases to act, and the broken
bar may be replaced by a fresh one and the machine again set in motion
by releasing the spring as above described, and so reproducing the
ascending and descending motion of the crank shaft, after which the
machine will again stand still.
In witness whereof, I, the said William Richter, have hercunto set
my hand and scal, this Sixth day of April, in the year of our
Lord One thousand eight hundred and seventy-two.
