FRANK WIRTH, of the Firm of Wirth & Co., Patent Agents, of Frankfort-on-
Maine, in the Empire of Germany. SCALING, CLEANING, AND POLISHING WIRE,
BY MEANS OF A NEW AND IMPROVED MACHINE." A communication from Nikolaus
Betz, Master Wire Drawer, now residing at St. Ingbert, in the Empire of Germany.
My improved machine is constructed in duplicate in such a manner that one-half
can be worked while the other remains standing.
Before describing my Invention I will give a short description of the uses to
which it is applied; rolled wire especially when rolled hot is covered with forge
scales or crust; if this wire is to be drawn cold it must first of all be entirely freed
from this crust; this operation has heretofore been accomplished by the use of
sulphuric acid; this manner of cleaning wire however is detrimental to the metal
and is now superseded by my said machine which removes the crust or scales with-
out injuring the metal.
The said machine has a cleaning box, wire reels, claw-shaped guides, a bed, a
trestle, a sliding carriage, a cross piece, a bed plate, wheels and pinions, a pulley,
drum, and chain.
The parts of the cleaning box are as follows, namely:-An axle, an axle box cover,
a crank shaft, a toothed wheel, a frog catch, guiding pins, a prism, engaging and
disengaging machinery, a box, roll, carrying shaft rollers, and a fly wheel.
In operating this machine a piece of rolled wire is placed on the reel just as it is
left by the rolls; one end is then attached to the said chain which is provided with
a button or catch at its end; the machine is now put in motion and the wire first
drawn through the claw guide which serves to take out any loops in the wire
caused by coiling it up hot after rolling; it now passes under roll number one, thence.
to number two, the so called stretching roll, where the wire is cleaned from scales
Danell

page_text: on its under side; roll number three now cleans the wire on its upper side; the wire
now passes over number four to roll number five where it is cleaned on its right
side, then to number six, left side; the rolls numbers one, two, three, and four are
placed vertically, numbers five and six horizontally; the wire after having passed
these rolls is entirely freed from all forge scales without having had its quality
injured in the least. The wire now arrives at the aforesaid cleaning box which is
filled with a mixture of calves' hair and sand; the chain being much thicker than
the wire would soon pull all the sand and hair out of the box if it passed through
the same, it is therefore carried over two half guide rolls which are placed so far
apart that they allow the wire to fall down between them into the box as soon as
the chain has passed over; the wire on leaving the box is clean and bright.
The ring-shaped button at the end of the chain coming in contact with the
engaging and disengaging apparatus, causes the said prism to fall, which on the
piece of wire being finished, is again lifted upon the fly wheel.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed 1
by the said Frank Wirth in the Great Seal Patent Office on the 27th June
1877.
FRANK WIRTH, of the Firm of Wirth & Co., Patent Agents, of Frankfort-on-
the-Maine, in the Empire of Germany. "SCALING, CLEANING, AND POLISHING
WIRE, BY MEANS OF A NEW AND IMPROVED MACHINE." A communication from
Nikolaus Betz, Master Wire Drawer, now residing at St. Ingbert, in the Empire of
Germany.
My improved machine is constructed in duplicate in such a manner that one-half
can be worked while the other remains standing.
Before describing this Invention I will give a short description of the uses to
which it is applied as follows:-Rolled wire especially when rolled hot is covered
with forge scales or crust; if this wire is to be drawn cold it must first be entirely
freed from this crust; this operation has heretofore been accomplished by the use of
sulphuric acid; this manner of cleaning wire however is detrimental to the metal,
and is now superseded by the said machine, which removes the crust or scales with-
out injuring the metal.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of a machine constructed according to the said In-
vention; Figure 2 is a top view of the same; Figure 3 is an end elevation of the
said machine.
In order that the said Invention may be more easily understood, I divide the
description of my machine into two parts, namely, the body and cleaning box.
As shown in the Drawings the body of my machine is marked A, and the
different parts are indicated with the small letters from a to r. The cleaning box
is marked B, and its parts numbered from 1 to 13.
The same letters and numbers refer to the same parts throughout the Drawings.
a, a, are wire reels; b, b, are claw-shaped guides; c, a bed; d, e, are supports;
f is a trestle; g is a sliding carriage; h is a cross piece; k is a bed plate; 1, 1, are
bearings; m, m, are axles of the driving wheel and pinion; n is the driving wheel;
o is the pinion; p is a pulley; 9 is a drum; r, a chain.
The parts of the cleaning box B are as follows:-1 is an axle box; 2 is the axle
box cover; 3 is a crank shaft; 4, a toothed wheel; 5, a frog catch; 7; guiding
pins; 8, a prism; 9, engaging and disengaging machinery; 10, a box; 11, a roll;
12, a carrying half roller; 13, a fly wheel
In operating this machine a piece of rolled wire is placed on the reel just as it is
left by the rolls; one end is then attached to the said chain which is provided with

page_text: a button or catch at its end; the machine is now put in motion and the wire first
drawn through the claw guide which serves to take out any loops in the wire
caused by coiling it up hot after rolling; it now passes under roll No. 1, thence to
No. 2, the so called stretching roll, where the wire is cleaned from scales on its under
side; roll No. 3 now cleans the wire on its upper side; the wire now passes over
No. 4 to roll No. 5, where it is cleaned on its right side, and then to No. 6, where it
is cleaned on its left side. The rolls Nos. 1, 2, 3, and 4, are placed vertically, and
Nos. 5 and 6 horizontally, as shewn in the Drawings. The wire after having passed
these rolls is entirely freed from all forge scales without having had its quality
injured in the least. The wire now arrives at the aforesaid cleaning box which is
filled with a mixture of calves' hair and sand; the chain being much thicker than
the wire would soon pull all the sand and hair out of the box if it passed through the
same, it is therefore carried over two half guide rolls which are placed so far apart
that they allow the wire to fall down between them into the box as soon as the
chain has passed over; the wire on leaving the box is clean and bright.
The ring-shaped button at the end of the chain, coming in contact with the
engaging and disengaging apparatus, causes the said prism to fall, which on the
piece of wire being finished, is again lifted upon the fly wheel.
The advantages of my Invention are as follows, namely:-
1. Heretofore to clean 1 cwt. of rolled wire 3 lbs. of sulphuric acid have been
needed; with my machine 1 lb. of calves' hair and 1 lb. of sand will clean 5 tons of
the same wire in a more effectual manner.
2. With a machine constructed in accordance with my Invention two workmen
will easily clean 10 cwt. an hour.
3. Cleaning wire in acid is a most unhealthy employment, and it has therefore
always been a very difficult matter to find workmen who thoroughly understood
the same.
Having thus fully described the said Invention and the manner of performing the
same, I wish it understood that I claim,-
First. Scaling, cleaning, and polishing wire, by means of the improved machine,
in the manner above described.
Second. In a machine for scaling, cleaning, and polishing wire, the wire reels a, a ;
the guides b, b; bed c; supports d, e; trestle f; carriage g; cross piece h; bed
plate ; bearings 1, 1; driving wheel n; pinion o; pulley p; drum q; chain r; in
combination with the cleaning box B, as above described and for the purpose set
forth.
In witness whereof, I, the said Frank Wirth, have hereunto set my hand
and seal, this Twenty-third day of June, in the year of our Lord One
thousand eight hundred and camenty seven
F. WIRTH. (LS.)
