Machinery for Cleaning Metallic Sheets or Plates.
Year: 1890

page_text: Machinery for Cleaning Metallic Sheets or Plates.
I, WILHELM GOES, Eugiueer, of Schalke, Westphalia, in the German Empire,
do hereby declare the nature of my invention to be as follows:-
My invention relates to machinery for cleansing sheet-metal such as in plates,
from grease and other impurities adhering to the same.
The sheets are drawn through the finely divided cleansing material by means of
clips or pincers fixed to an endless pitch chain. The weight of the cleaning
material, such as bran, saw-dust etc., situated in suitable boxes, is generally
sufficient to cleanse the sheets from grease and other impurities adhering to
the same.
The machine works as follows:-
The sheet to be cleansed is laid on a series of feed rollers which transport it
towards the clips, but a detent or retaining device, holds the sheet back until on the
travelling chain a clip is opened. As soon as this has occurred, the sheet enters
the open mouth of the clip, the latter closes and draws the plate through the
material contained in the first cleansing box, as far as the second (hexagonal)
chain wheel. Here the clip opens again, releases the plate, which remains ou a
series of transporting rollers. As those spots, of the plate, which have come in
contact with the clips, are cleansed imperfectly, the plate is drawn through a
second cleansing box similar to the first, but the pitch chains and clips of this
apparatus are so arranged relatively to the first, that those portions of the plate
which have been in contact with the clips of the first apparatus are exposed freely
to the cleansing material while passing through the second cleansing box.
A. brush is applied behind the first and the second cleansing box for wiping off
the cleaning material which lies on the plate. The plate coming out of the second
cleaning box is furthermore subjected to a revolving brush, and then passed between
a pair of revolving brushes, which complete the work of cleaning..
The floor of each cleansing box is formed by a horizontally reciprocating sieve or
false bottom which causes a slow, but constant sinking of the cleansing material in
the box, so that each succeeding plate comes in contact with a fresh layer of
cleaning material. The material wiped off by the brushes falls through a shoot
into the lower part of the cleansing box, while that which has passed through the
sieve or false bottom is lifted by an endless bucket chain and then discharged into
the upper part of the cleansing box.

Machinery for Cleaning Metallic Sheets or Plates.
I, WILHELM GOES, Engineer, of Schalke. Westphalia, in the German Empire,
do liereby declare the nature of my invention and in what manner the same may
be performed, to be particularly described and ascertained in and by the following
statement:.
My invention relates to machinery for cleansing sheet-metal, such as tin plates,
from grease and other impurities adhering to the same.
In the accompanying drawings, Fig. 1 is a longitudinal vertical section, Fig. 2 a
cross section, and Fig. 3 a plan of a machine embodying my invention.

page_text: The sheets are drawn through the finely divided cleausing material by means of
clips or pincers -fixed to an endless pitch chain . The weight of the cleaning
material, such as bran, saw-dust etc., situated in suitable boxes K, K is generally
sufficient to cleanse the sheets from grease and other impurities adhering to
the same.
The machine works as follows:-
The sheet to be cleansed is laid on a series of feed rollers or on an endless apron a
which transports it towards the clips, but a detent or retaining device 6 holds the
sheet back, until on the travelling chain a clip is opened. As soon as this has
occurred, the sheet enters the open mouth of the clip, the latter closes and draws
the plate through the material contained in the first cleansing box K, as far as the
second (hexagonal) chain wheel . Here the clip opens again and releases the
plate, which remains on a series of transporting rollers.
Each of the said clips consists of two parts, namely a straight post of flat iron
fixed to the front end of a chain link, and an angle-piece fixed to the rear part of
the preceding link, so that when the chain is stretched out, the angle-piece over-
hangs the said post and clips the front part of the sheet which rests on the rounded
top of the flai post. As soon as the link carrying the angle-piece reaches the chain
wheel (n) and is carried downward by the same, the overhanging part will
recede from the sheet resting on the post and thereby release it from the clip. The
sheet will now be pushed by the back of the following angle-piece on io the
next preceding chain, where it is seized by a similar clip and thereby carried
forward.
The said detent or retaining device 6 consists of two arms mounted on pivotal
pins, one of the said arms being directed upward, as shown in Fig. 1, while the
other is inclined downward, in which position these arms are held, either by the
greater weight of the lower arm, or by means of a suitably applied spring. During
The up motion of the clip, its angle-piece as well as its straight post come into
contact with a projection of the said pin, thereby causing the said upper arm to
drop below the horizontal plane of the endless apron . after which the plate of
sheet metal is free to enter the clip and is seized by the same. As those parts of
the plate, which have come in contact with the clips, are cleansed imperfectly, the
plate is drawn through a second cleansing box K' similar to the first, but the pitch
chains and clips of this apparatus are so arranged relatively to those of the first
box K. that when the plate is introduced into the clips of the chains, those
portions of the plate, which have been in contact with the clips of the first
apparatus, are not touched by the clips of the second apparatus, but are exposed
freely to the cleansing material, while passing through the second cleansing box.
and shown by dotted lines are the chain wheels of the second apparatus.
A brush or scraper is applied behind the first and the second cleansing box for
wiping off the cleansing material, which lies on the plate. The plate coming out of
the second cleansing box is furthermore subjected to a revolving brush, and then
pushed (by the back of the following clip 2) between a pair of revolving brushes f
which complete the work of cleaning. are a pair of transporting rollers which
seize the plate, after it has passed the brushes f. f and deliver it upon ai iable, or
carriage placed at the rear end of the machine.

contact with a fresh layer of cleansing material.
falls into a
The cleansing material, which has passed through the sieve
réceptacle below the cleansing hos, and that which is wiped off by the brushes is
guided into the same receptacle by means of a shoot t. An endless bucket chain E.
or a pair of such chains. serves to lift the cleansing material again above the
cleansing box and to deliver it into the latter, as shown by Fig. 2, thus utilizing
the same material repeatedly.
'
Instead of placing the second box K' longitudinally behind the first, it may be

that side.
If an endless feed-apron a is employed, brau or similar material may be deposited
on the same by means of a bucket chain E which is situated in front of the first box K
and delivers the bran to the feed apron by means of suitably arranged tubes.
Arms mounted in the boxes K and K, and receiving besides their rotary
motion also an excentric motion, serve to transport the bran or other cleansing
material.
Having thus particularly described the nature of my said invention and in
what manner the same is to be performed, I declare that I claim-
A machine for cleaning sheets or plates of iron or similar material, having the
characteristic feature, that the sheets to be cleaned are laid on an endless feeding
apron then released from the holder, then seized by clips of endless pitch
chains and drawn by them through the first cleaning box K, subsequently seized
by clips of pitch chains (out of line with the first), and drawn by the same
through a second cleaning box K', subsequently relieved of the adhering cleaning
material by brushes, and finally delivered on a table by means of rollers g: the
said machine being provided with reciprocating sieves placed in the cleaning
boxes and serving to produce a continual changing of the layers of cleaning
material, with which the sheets come into contact, and with a laterally placed
elevator E adapted to return in the top of the cleaning box the cleaning material
which has dropped through the sieve, substantially as described.
