Improvements in Machines or Apparatus for Manufacturing
Tin Plates.
I, EDWIN NORTON,. of Maywood, Chicago, County of Cook, State of Illinois.
United States of America, Manufacturer, 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 :-
My invention relates to the manufacture of tin plate.
The object of my invention is to produce an improved process or method of an I
apparatus or combined machine for manufacturing tin plate which will operate to
continuously and automatically dry and flux the wet picklel sheets of iron or steel,
to tin them, to lift them from the tinning pot and cool them, to clean the tinned
sheets from the oil while they are still warm or hot, and finally to dust and polish
them while still hot or warm, all these steps being performed continuously in the
combined machine without hand labor.
My invention consists in the combination in one complete machine or apparatus
of a device or mechanism for automatically feeding the wet pickled sheets one by
one, a device or mechanism for drying and fluxing the wet picklel sheets, a device
or mechanism for tinning the fluxed sheets automatically, a device or mechanism for
lifting or conveying the sheets from the tinning pot as they issue therefrom, said
lifting device operating to hold the sheets suspended the necessary interval of tim>
for cooling the sheet sufficiently to allow the tin coating thereon to become set, a
device or mechanism for cleaning the sheets, and a device or mechanism for
polishing the tinned sheets, all these different parts or devices of the machine
being combined together and co-operating one with another, so that the sheets pass
successively and continuously through the cutire machine without the necessity of
any intermediate handling or hand labor.
It also consists in the novel construction of parts and devices and in the novel
combinations of parts and devices entering into the construction of my combined
machine or apparatus.
In the accompanying drawing which forms a part of this Specification, and in
which similar letters of reference indicate like parts,
Fig. 1 is a side elevation of a machine or apparatas embodying my invention;
Figs. 2 and 3 are enlarged detail views of a part or device hereinafter
described;
Fig. 4 is a detail vertical sectional view of the sheet drying and fluxing
mechanism, and Fig. 4ª is a side elevation of the same; and
Figs. 5, 6 and 7 are enlarged detail views of the lifting and cooling mechanism.
In the drawing A represents the frame of the apparatus or machine. B is the
device or mechanism for automatically feeding the wet pickled sheets one by one
to the machine. This sheet feeding mechanism consists of a table E in connection
with one or more vibratory feed arms 6' secured to a rock shaft 6 below the fee.l
table and which work back and forth in suitable slots or openings E' in the feed
table E. The vibrating feed arms b' are operated automatically at suitable
intervals by any convenient connecting mechanism, such for example as an arm b*
on the rock shaft 63, pivoted link 6, connected to arm 6 on the rock shaft 67. The
rock shaft b' is provided with an arm 68 connected by a link 6º with a lever b¹º,
which is actuated by a cam 6" on the cam shaft K.
C is the drying and fluxing device by which the water or moisture is driven off
the wet pickled sheets and the same coated on both sides with palm oil or other

page_text: suitable flux. This drying and fluxing device or mechanism consists of two pairs
of hollow steam heated fluxing rolls cc and cc and a pair of hollow steam heated
drying rolls el el in conjunction with a flux tank c, a flux feed roll c³ revolving in
the flux tank and a transfer roll crevolving in contact with the flux feed roll c
and one of the fluxing rolls c. The flux tank c has a hollow steam heated
chamber for heating the palm oil or flux contained in said tank. The flux
tank is located above the path of the sheets of iron or steel through the machine,
and preferably directly above one pair of fluxing rolls cc, substantially as indicated
in the drawing. The flux feed roll revolving in the flux tanke is partially
immersed in the oil or flux and serves to feed or supply the flux to the fluxing
rolls through the medium of-the transfer roller c which revolves in contact with
the flux feed roll c³ and also in contact with the upper one of the first pair of
fluxing rolls cc, by which fluxing roll the flux or oil is transferred to the surface of
the other fluxing rolls by direct contact therewith or by contact with the sheet to
the upper and lower surfaces of which the flux or oil has been transferred by the
first pair of fluxing rolls c c. The pair of steam heated rolls o el adjacent to the
feed table 6 are preferably used simply as drying rolls, and no flux or oil need be
supplied to them. CC are the steam pipes connected to the several pairs of
hollow heated fluxing and drying rolls by suitable stuffing boxes and also com-
municating with the steam chamber of the flux tank. As the sheets are
automatically fed at intervals, or intermittently, by the sheet feed device they
pass at intervals between the pairs of drying and fluxing rolls, so that the flux
supplied to the surface of the upper one of the first pair of fluxing rolls by the
flux feed roller, may be transferred to the surface of the lower fluxing roll of this
first pair at the intervals between the successive sheets, at which intervals the
upper and lower fluxing rolls are in direct contact with each other. The various
rolls, c, c, c, c are all driven by suitable connecting gearing d¹º, g¹º, ƒ¼¼º from the
driving shaft M, as is also the delivery roll c³.
D is the tinning device or mechanism. The tinning device or mechanism
consists essentially of a tinning pot d furnished with tinning rolls d' d', finishing
rolls dd, intermediate rolls d³ ³ and guides d for conveying and guiding the
sheets through the tinning pot. The tinning pot is also provided with a hopper,
chute or feed passage D' connecting with or forming a part of the chute or feed
passage C' by which the sheets are successively and automatically conveyed or
passed from the fluxing mechanism C to the tiuning mechanism D.
F is the device for lifting or conveying the sheets successively one by one as
they issue from the tinning pot and supporting or suspending the same a sufficient
length of time to allow the molten tin upon the surfaces of the sheet to become
cooled or set. The sheet lifting and cooling mechanism consists essentially of an
endless link chain carrier f furnished with a series of pairs of opening and closing
fingers ff which grasp the sheet at or near its upper edge, these fingers being
automatically operated by stationary cams on the frame A of the machine, in
conjunction with a deflector device for pushing or deflecting the lower edge of
the sheet over the mouth or edge of the chute by which the sheet is passed or
conveyed to the cleaning device or mechanism. This deflector device consists
preferably of a revolving arm mounted on the frame in co-operative relation or
combination with the chute F', the carrier f and the cam which opens or permits
the opening of the fingers f'' to release the sheet, so that the deflector device
will push or deflect the sheet as it drops into the chute F. Two endless chains f
are employed, the same being carried on pulleys ff* revolving in opposite direc-
tions, so that the two contiguous or inuer loops of the two link chains will travel
in the same direction and co-operate together, the two chain carriers ff being
placed far enough apart to give room for the sheet or sheets of the tin plate to be
suspended between them. To properly guide the flexible chain carrier ff the
frame A is provided with tracks or ways f³ for each of these chain carriers.
The opening and closing movement of the lifting fingers is provided for by
pivoting or hinging the fingers to the carrier, as at j; and they are closed and

page_text: held closed so as to properly grasp and support the sheet of tin plate by means of
the stationary cams, which should preferably be fixed adjustably to the frame A².
The movable fingers flf are preferably furnished with anti-friction rollers to
bear against the stationary cam. By this lifting device the sheets of tin plate,
as they issue one after another from the finishing rolls d'd of the tinning pot d
are grasped at the upper corners of each sheet by the opposite pairs of lifting
fingers on the shain carriers ff, and the sheet thus suspended by and between
said carriers is conveyed upward for a suitable height and time to give the
necessary opportunity for the tin coating to become sufficiently set or cool to
prevent marring or injuring by contact with the discharge chute or sheet deflector
device; and then, by operation of the stationary cams the lifting fingers are
automatically opened and the sheet released, when it descends along the discharge
chute F, its lower edge being deflected over the mouth of the discharge chute F
by the deflector device f³. The stationary cams are fixed to the lifter frame A*
by screws f, and are adjusted closer together or farther apart by adjusting
screws 10 inserted between these stationary cams. By adjusting the stationary
cams farther apart the bite or pressure of the pivoted fingers upon the sheet of
tin plate will be increased. Each of the lifting fingers of is also preferably made
independently or individually adjustable. This is preferably done by making each
of the fingers in two parts one adjustable on or in respect to the other. The
part fcf finger f which bears directly against the sheet of tin plate, is preferably
made of vulcanite, wood fibre or like material that will not become tinned or tend
to mar the hot and more or less soft coating of tin on the sheet as it issues fresh
from the tinning pot. And I preferably make the bearing part or pin fll adjust-
able on the main part of the finger by means of an adjusting screw f". The
lifter frame A2 is preferably connected to and supported by brackets F³ at or near
its upper end, which brackets F³ may be attached to a beam F of the building.
At or near its lower end the lifter frame A is removably secured by bolts or
pins to brackets or arms f" attached to the tinning pot D.
G is the cleaner device or mechanism. The cleaner device or mechanism consists
essentially of an endless flexible skeleton conveyor 9 and a bin or receptacle
containing bran or other cleaning material through which cleaning material the
sheets are drawn or passed successively and continuously by the conveyor g. The
skeleton conveyor g consists of link chains travelling upon suitable pulleys, and
furnished with a series of open racks, pockets or fingers g¹ for receiving and holding
the tinned sheets and conveying them through the mass of bran or cleaning
material in the bin or receptacle G, the racks, pockets or fingers being open so
as to permit the mass of bran to come in contact with the surface of the loose
sheets on both sides.
The connecting chute Flis arranged preferably in substantially the same direction
or inclination as the receiving portion or loop of the endless flexible conveyor g of
the cleaning mechanism G so that when the tinned sheets pass down to the lower
end of the chute F', they will be in the path of the open pockets or fingers g¹ of the
conveyor g and thus be received thereby. The chute F' is provided with one or
more, preferably two, spring stops and f' to cushion the fall or motion of the
sheet to prevent injury to the same. The upper one f* of these stops is mounted
on a movable arm, so that it may be moved out of the way at intervals to permit
the sheet to pass down against the next stop in position to be received by
the carrier pocket g'. The arm fe is operated at suitable intervals by a cam or pro-
jection gg on the pulley g of the carrier g of the cleaning mechanism. The
movable stop thus operates as a feed check, or device to prevent more than
one sheet being fed or passed at a time down against the stop in position
to be received by the carrier of the cleaning mechanism. The stop is
preferably made in the form of a spring, as indicated in the drawing, and
is also secured to a sliding stem f' which is surrounded and supported by a coil
spring f. The spring f8 is partially enclosed in a barrel or case 15 attached to an
open pocket or receptacle f1f", the bottom limb f1 of which forms a continuation
4

page_text: of the chute F', and the upper limb f" of which is curved upward to tangentially
meet the pulley 95 of the carrier 9 of the cleaner mechanism. The slots or
opening fare for the purpose of receiving and permitting the fingers or pockets g¹
of the cleaner carrier
to pass.
His the polishing device or mechanism. This polishing device or mechanism
consists essentially of a series of felt covered polishing rolls between which the
sheet is fed or passed by the feed rolls ', the rolls being mounted in an enclosing
case and the sheets being fed directly and automatically to the polishing device
by a chute or passage way h³. From the polishing device the sheets are auto-
matically delivered into a suitable truck or receptacle K² by the delivery chute or
passage h*.
M is a water tank or receptacle from which the sheets are taken preparatory
to being fed to the drying and fluxing device.
All these parts or mechanisms are geared and connected together by suitable
driving mechanism so that the sheets pass continuously and successively from the
feeder B to the drying and fluxing device C, thence to the tinning device D, thence
to the lifting and cooling device F, thence to the cleaning device G, thence to
the polishing device H, and finally onto the truck or receptacle K. And as the
sheets still retain considerable of their heat while passing through the cleaning and
polishing devices, this warmth or heat of the sheets greatly facilitates not only the
removal of the oil or grease from the sheets by the cleaning mechanism, but also
the final step of polishing the sheets.
"
The operation is as follows: The wet pickled sheets are taken by the operator
from the water tank containing them and placed one by one on the feed table 6 in
front of the feeder arm b¹. The intermittent movement of the feeder arm b'auto-
matically feeds or pushes the sheet forward into the bite of the steam heated drying
rolls cc which serve to free the sheets from a large part of the water or moisture
upon their surfaces. By these drying rolls c¹ c¹ the sheet is fed forward into the bite
of the front pair of drying and fluxing rolls c c from whence it passes into the next
pair and thence on through the machine. The surface of the upper one of the first
pair of fluxing rolls is continually supplied with palm oil or other flux from the
Hux tank through the medium of the feed roll and transfer roll c¹; and from
the surface of this first upper fluxing roll the oil or flux is transferred to the lower
roll of this pair as the intervals when no sheet is between these rolls; and at the
intervals when the sheet is passing between these two first fluxing rolls the flux is
transferred from the surface of both rolls to this pair to the upper and lower surfaces
of the sheet. And from the upper and lower surfaces of the sheet the oil or
flux is transferred to the second or next pair of fluxing rolls cc, so that all four of
the fluxing rolls are kept well coated with the oil or flux and the same is thus
thoroughly and evenly distributed over both surfaces of every sheet by the combined
action of the two pairs of fluxing rolls. As all four of the fluxing rolls are heated
they also operate to drive off any remaining water or moisture that may be on
the sheet after passing between the drying rolls o c¹. The intermittently operating
feeder arm b' is timedin relation to the speed of the drying and fluxing rolls so as to
properly coact therewith and give opportunity at the intervals between successive
sheets for the flux to be transferred from the upper to the lower fluxing roll, and
also to give time for the heated rolls to drive off the moisture from the surfaces of
the sheets. As the wet sheets pass between the rolls the water or moisture is in part
driven off by the heat, and in part by the pressure of the rolls upon the sheet,
the water expelled by the latter or squeezing operation having, by the arrange-
ment of the flux tank above the path of the sheets, free opportunity to drop down
or drain off without the necessity of being evaporated by the heat or mixed with the
oil or collected in the oil or flux tank. The sheets thus dried, fluxed and heated
next pass automatically one after another into and through the tinning mechanism D
and as the freshly tinned sheets are issued or passed upward by the finishing
rolls d² of said tinning mechanism, they are automatically grasped at their corners
one after another, by the fingers of the lifting mechanism F and conveyed upward

page_text: until the tin coating has become sufficiently set: when the lifting fingers open
releasing the sheet, which is then deflected into the chute F' by which it is
conveyed into the pocket or receptacle "/", from which it is taken by the
pocket g of the conveyor g and carried through the bran or cleaning material in the
cleaner G. The carrier g of the cleaner G then delivers the sheet into the chute or
passage leading into the polishing or dusting mechanism H; and the sheet then
after passing between the polishing or dusting rollers h³ is finally delivered into the
truck K², the whole operation being automatic and continuous.
