Improvements in Apparatus for Cleaning or Branning Tin and
Terne Plates or the like.
I, ALBERT ERNEST GARDNER BIRKBECK. of Burry Cottage, Penclawdd, in
the County of Glamorgan, Assistant Manager of Tinplate Works, do hereby
declare the nature of this invention to be as follows:-
This invention relates to apparatus for mechanically cleaning or "branning" tin
or terne or the like plates after they leave the coating pot-the object being to
clean off the grease adhering to such plates after coming through the grease (or
grease pot") such operation having usually heretofore been effected by hand
though I am aware that attempts have been made to effect this object by
mechanical means.
66
Now the object I have in view is to provide simple and effective means to draw
the plate through the "bran" or other cleaning material instead of pushing it
through.
For this purpose I proceed as follows:-
In a suitable trough or receptacle or receptacles for holding the bran or other
cleaning material I arrange and mount two sets of apparatus the first set to draw
the plate through in one direction and the second set to draw it through the second
time in the reverse direction.
Each set of apparatus is similar and therefore I will only describe the first set.
The apparatus is as follows:-
A rotating shaft or axle (driven by any suitable power) passes through suitable
bearings in or on the side walls of the trough (or mounted in any other suitable
support) and such shaft carries one, two, or more sets of gripping appliances for
gripping the plates-each set of gripping appliances being as follows:-
Four arms or rods (or it may be more or less than four) are fixed rigidly upon
the said revolving axle and each at its outer end carries a bent over arm or nipping
piece which forms one part of the gripper or plate nipper. Upon this arm are
carried guide pieces in the ends of which a second arm or movable rod is carried so
that said rod is free to slide in these guide pieces in the direction of the length of
the aforesaid arm fixed on the said shaft. This sliding rod is formed in two parts
being divided at about its middle and has a suitable spiral spring of suitable
strength arranged between the divided ends of this sliding rod so that when one
part thereof is moved the said spring is compressed and the other part moved
accordingly.
Suitable nuts or washers or the like devices are mounted upon these rods so as to
set up the spring and adjust same as required i.e. I provide means to increase or
diminish the tension upon said spring.
At the outer end of said sliding rod is pivotted one end of an arm or lever which
latter is pivotted also to the outer end of the fixed arm and this pivotted arm or
lever forming the other part of the plate gripper.
Towards the inner end of said sliding rod a hole or slot is provided through
which passes a transverse rod-this rod also passing through similar holes or slots
in each of the other sliding rods in such set of grippers and at each end of this
transverse rod an arm is mounted extending centrally towards the main revolving
shaft.
This short centrally projecting arm passes through guides or guiding pieces
pivotted on two short outwardly projecting arms mounted upon the said main shaft

page_text: so as to revolve therewith and at the end of each said centrally projecting arm is a
small loose wheel or other suitable surface to ride upon a cam fixed against the side
wall of the said trough or receptacle for holding the cleaning material or said cam
may be fixed to the bearing .or support in which the said main shaft revolves or
mounted in any other suitable manner.
A cam is thus fixed at each side of said apparatus and as before stated this cam
does not revolve.
The operation is as follows:-
Upon the main shaft being revolved it will carry round the said set of arms each
arm respectively having a gripping device (of the character described or other
equivalent character) at the outer end thereof and the said two centrally projecting
arms on the outer ends of the transverse bar being held in contact with the cams
the said wheels on these centrally projecting arms will ride up on to the larger
part of the cams and thus push out the transverse bar and with it the sliding rods
so that the said spiral spring is compressed and the nipping jaws or grippers are
pressed together and so nip the plate placed therein between.
This gripping pressure will be kept up until the ends of the said centrally
projecting arms pass over the higher part of the cam and drop back into the
smallest part thereof whereupon the gripping jaws will be released and will be
pulled open by. a suitable spring provided for so doing said nipping jaws or
gripping devices will then remain open until said ends of the centrally projecting
arms ride again up the higher part of the cam whereupon the jaws will again be
closed as before.
Instead of having the said centrally projecting rods on the ends of the transverse
rod-each end of said transverse rod may have a wheel or other surface thereon .to
come in direct contact with the said cams respectively-the centrally projecting
arms being entirely dispensed with and the ends of the transverse bar passing
through guiding slots in the aforesaid outwardly projecting arms fixed on and
rotated by and with the main shaft and if desired the cams may be made of a
larger size so as to thus act direct.
Any suitable number of such sets of gripping devices can be mounted upon said
main shaft but it will be found in practice that three or four such sets will be
sufficient.
The plates are fed into the said nipping jaws by any suitable mechanical
feeding device or by hand as desired and after being drawn through the bran
the first time they are released and drop into the second set of nipping jaws
or gripping devices mounted on a second main shaft (similar to that above
described) and are then drawn a second time through the bran or other cleaning
material in the reverse direction to that in which they were first drawn through.
Upon arriving out of the cleaning material a second time the nipping jaws open
as before described and allow the plate to drop out on to a slide or table or other
convenient receptacle from which they are removed in any desired manner.
Any suitable tilting device may be arranged to act for the purpose of trans-
ferring each plate from the first to the second set of gripping devices and from the
second set clear of the said trough (or receptacle for bran et cetera) into or onto
the receiving table or receptacle as above.
I may if desired however provide for this purpose a special tilting arm or arms
which are pivotted to the aforesaid fixed arms in any suitable manner and actuated
in a similar manner to the hereinbefore described sliding rods by means of the
same or similar cams so that at the desired moment such tilting arms will swing
out and give the released plate the desired direction and thereafter such tilting
arm will return close against fixed arm or out of the way and remain there until
required to tilt the next plate to be released and so on.
In place of using the above mentioned "tilting" device for the purpose described
I may use the following device :-
At the delivery end of the first trough and in a suitable position outside the line
of travel of the aforesaid nipping jaws is mounted a fixed transverse bar or rod.

page_text: On this bar are mounted downwardly and outwardly curved guides their lower
ends lying just within the line of travel of said nipping jaws.
Between the circles respectively struck by the two separate nipping jaws
(i.e. between their respective lines of travel) a fixed incline is arranged or suitably
mounted upon which the plate is dropped and fed into the second trough.
A similar transverse bar and similar downwardly and outwardly projecting
guides and delivery incline are mounted at the delivery end of the second trough,
The several parts may be made of metal or other suitable material or com-
binations of materials and all the parts being simple and easily manufactured I am
able to produce a very convenient and practical cleaning machine at small cost and
an apparatus that is not liable to get out of order or injure the plates especially
thin plates as has usually been the case with machines heretofore designed for
effecting a similar purpose.
The following is a suitable and advantageous mechanical feeding device to feed
the plates one by one into the hereinbefore described grippers.
At the feed end of the trough a suitable rest or support is arranged and mounted
on a slant (somewhat after the manner of the head rest of a reading desk or music
stand) and has removable stops or bottom rail thereto upon which the lower edge
of the plate rests until the said removable stops are pushed back by the rotating
grippers whereupon the plate slides off into the open jaws or grippers which at the
noment are just ready to receive same and thereafter they immediately snap hold
of said plate and pass same through the bran or cleaning material as previously
described and then may deliver such plate onto a second similar mechanical
feeding device to be similarly fed into a second set of grippers or otherwise as
desired.
My feeding mechanism is as follows:-
I interpose in the path of travel of some part or parts of the revolving gripper
mechanism or in the path of a wheel or other special attachment thereto-
a curved or other head or end of a slide rod mounted or held in suitable guides.
This slide rod is pivoted to a crank arm on a rocking shaft or other suitable
device which has likewise fixed thereto a second crank arm pivotted to the back
end of the said movable stops or under supports for the plate on the "rest"; or
the said slide rod may be connected up direct to the said back end of the movable
stops on a rocking axle or in any other equivalent or suitable manner so that when
the said slide rod is (periodically) pushed out of the path of travel of the said
moving part of or on the rotating gripper arms such movement will thereby remove
the under support from beneath the lower edge of the plate on the "rest" just at
the right moment to drop said plate into the open jaws of the gripper ready to
seize and grip same.
I do not however wish to confine myself to using this particular feed mechanism.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Cleaning or Branning Tin and
Terne Plates or the like.
I, ALBERT ERNEST GARDNER BIRKBECK of Burry Cottage, Penclawdd
in the County of Glamorgan, Assistant Manager of Tinplate Works, 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 invention relates to apparatus for mechanically cleaning or "branning" tio
or terne or the like plates after they leave the coating pot the object being to

page_text: clean off the grease adhering to such plates after coming through the grease
(or "grease pot") such operation having usually beretofore been effected by
hand though I am aware that attempts have been made to effect this object by
mechanical means.
"
Now the object I have in view is to provide simple and effective means to draw
the plate through the "brau or other cleaning material instead of pushing it
through.
For this purpose I proceed as follows:-
In a suitable trough or receptacle or receptacles for holding the bran or other
cleaning material I arrange and mount two sets of apparatus the first set to draw
the plate through in one direction and the second set to draw it through a second
time but in the reverse direction.
Each such set of apparatus is similar and therefore I will only describe the
first set.
The apparatus is as follows :-
A rotating shaft or axle (driven by any suitable power) passes through suitable
bearings in or on the side walls of the trough (or mounted in any other suitable
support) and such shaft carries one, two or more sets of gripping appliances for
gripping the plates-each set of gripping appliances being as follows
:-
Three arms or rods (or it may be more or less than three) are fixed rigidly upon
the said revolving axle (advantageously in any suitable adjustable manner) and each
at its outer end carries a bent over arm or nipping piece which forms one part of
the gripper or plate nipper. Upou this arm are carried guide pieces in which a
second movable arm or rod is carried so that said rod is free to slide in these guide
pieces in the direction of the length of the aforesaid primary arm fixed on the
said shaft. This sliding rod may be formed in two parts being divided at about
its middle and has a suitable spiral spring of suitable strength arranged between
the divided ends of this sliding rod so that when one part thereof is moved the said
spring is compressed and the other part is moved accordingly or as an equivalent
arrangement this secondary rod may be in one part only having one end of the
said spring advantageously adjustably fixed thereto and the other end of said
spring attached to or resting against a stop or rest either fixed or movable on the
transverse rod-the mechanical effect or grip imparted thus to this secondary arm
being the same in all cases or such movement or grip between the said primary and
secondary arms may be imparted thereto in any other suitable manner.
Suitable nuts or washers or the like devices are mounted upon these rods so as
to set up the spring and adjust same as required i.e. I provide such or other suitable
means to increase or diminish the tension upon said spring.
At the outer end of said sliding rod is pivotted one end of an arm or lever
which latter is pivotted also to the outer end of the fixed arm and this pivotted arm
or lever forming the other part of the plate gripper or the outer end of the
secondary rod may move direct against the turned over end of the primary rod
and thus form the gripper.
Towards the inner end of said sliding rod a hole or slot bend or abutment is
provided through or against which passes a transverse rod-this rod also passing
through or against similar slots etc. in each of the other sliding rods in such set
of grippers and at each end of this transverse rod an arm is mounted extending
centrally towards the main revolving shaft.
This short centrally projecting arm passes through guides or guiding pieces
pivotted on two short outwardly projecting arms mounted upon the said main shaft
so as to revolve therewith and at the end of each said centrally projecting arm is
a small loose wheel or other suitable surface to ride upon a cam fixed against the
side wall of the said trough or receptacle for holding the cleaning material or said
cam may be fixed to the bearing or support in which the said main shaft revolves
or mounted in any other suitable manner.
A cam or equivalent is thus fixed at each side of said apparatus and as before
stated this cam does not revolve.

page_text: The operation is as follows:-
Upon the main shaft being revolved it will carry round the said set of arms
each arm respectively having a gripping device (of the character described or other
equivalent character) at the outer end thereof and the said two centrally projecting
arms on the outer ends of the transverse bar being held in contact with the cams
the said wheels on these centrally projecting arms will ride up on to the larger
part of the cams and thus push out the transverse bar and with it the sliding rods
so that the said spiral spring is compressed and the nipping jaws or grippers are
pressed together and so nip the plate placed therein between.
This gripping pressure will be kept up until the ends of the said centrally
projecting arms pass over the higher part of the cam and drop back into the
smaller part thereof whereupon the gripping jaws will be released and will be
pulled open these movements being caused by a suitable spring or springs provided
for this purpose said nipping jaws or gripping devices will then remain open until
said ends of the centrally projecting arms ride again up the higher part of the cam
whereupon the jaws will again be closed as before.
Instead of having the said centrally projecting rods on the ends of the trans-
verse rod each end of said transverse rod may have a wheel or other surface.
thereon to come in direct contact with the said cams respectively-the centrally
projecting arms being entirely dispensed with and the ends of the transverse bar
passing through guiding slots in the aforesaid outwardly projecting arms fixed on
and rotated by and with the main shaft and if desired the cams may be made of a
larger size so as to thus act direct.
Any suitable number of such sets (consisting of two or other suitable number
of such plate gripping devices to each set) can be mounted upon said main
shaft but it will be found in practice that three or four such sets will be
sufficient.
The plates are fed into the said nipping jaws by any suitable mechanical feeding
device or by hand as desired and after being drawn through the bran the first time
they are released and thence drop into the second set of nipping jaws or gripping
devices mounted on a second main shaft (similar to that above described) and are
then drawn a second time through the bran or other cleaning material in the
reverse direction to that in which they were first drawn through.
Upon arriving out of the cleaning material a second time the nipping jaws open
as before described and allow the plates to drop out on to a slide or table
or other convenient receptacle from which they are removed in any desired
manner.
Any suitable tilting device guides etc. may be arranged to act for the purpose of
transferring each plate from the first to the second set of gripping devices and
from the second set clear of the said trough (or receptacle for bran et cetera) into
or onto the receiving table or receptacle as above.
In place of using a "tilting" device for the purpose described I may use the
following device :-
At the delivery end of the first trough and in a suitable position outside
the line of travel of the aforesaid nipping jaws is mounted a fixed transverse bar
or rod.
On this bar are mounted downwardly and outwardly curved guides their lower
ends lying just within the line of travel of said nipping jaws.
Between the circles respectively struck by the two separate nipping jaws
(i.e. between their respective lines of travel) a fixed incline is arranged or suitably
mounted upon which the plate dropped and fed into the second trough.
A similar transverse bar and similar downwardly and outwardly projecting
guides and delivery incline are mounted at the delivery end of the second
trough.
The several parts may be made of metal or other suitable material or com-
binations of materials and all the parts being simple and easily manufactured I am
able to produce a very convenient and practical cleaning machine at small cost and

page_text: -an apparatus that is not able to get one of order of the plates especiany
thin plates as has usually been the case with machines heretofore designed for
effecting a similar purpose.
The following is a suitable and advantageous mechanical feeding device to feed
the plates one by one into the herein before described grippers.
At the feed end of the trough a suitable rest or support is arranged and
mounted on a slant (somewhat after the manner of the head rest of a reading
desk or music stand) and has removable stops or bottom rail thereto upon which
the lower edge of the plate rests until the said removable stops are pushed back
by the rotating grippers (or vice versa that is the support for the plate may be
suitably moved clear of said stops or retaining ledge which latter in such case may
The fixed) whereupon the plate slides off into the open jaws or grippers which at
the moment are just ready to receive same and thereafter they immediately snap
hold of said plate and pass same through the bran or cleaning material as previously
described and then may deliver such plate onto a second similar mechanical
feeding device to be similarly fed into a second set of grippers or otherwise as
.desired.
My feeding mechanism is as follows:-
I interpose in the path of travel of some part or parts of the revolving gripper
mechanism or in the path of a wheel or other special attachment thereto-a
curved or other shaped end of a slide rod or pivoted rod or crank mounted or held
in any suitable manner.
This releasing rod is pivoted to a crank arm on a rocking shaft or other suitable
levice which has likewise fixed thereto a second crank arm pivoted to the back end
of the said movable stops or under supports for the plate on the "rest"; or the said
releasing rod may be connected up direct to the said back end of the movable
stops on a rocking axle or in any other equivalent or suitable manner this releasing
rod may be caused to move the said "rest" clear of the stops so that when the
said releasing rod is (periodically) pushed out of the path of travel of the said
moving part of or on the rotating gripper arms or axles thereof such movement
will thereby remove the under support from beneath the lower edge of the plate
on the "rest" just at the right moment to drop said plate into the open jaws of
the gripper ready to seize and grip same.
I do not however wish to confine myself to using this particular feed mechanism.
And in order that present invention may be easily understood and readily
carried into practice I will proceed to describe same with reference to the drawings
hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a general side view partly in section showing a machine or apparatus
according to my present invention.
.
Fig. 2 is a plan of Fig. 1-but on a smaller scale.
Fig. 3 is a side view in elevation of Fig. 2.
:
· Fig. 4 is a "local" side view of the gripper arms removed from the machine-but
on a very much enlarged scale.
or
Fig. 5 is a "local" end view on an enlarged scale of the bearer arms
radiating arms on each end of the main axle carrying the transverse rods and
springs which impart the releasing motion to the aforesaid gripping arms Fig. 4.
Similar letters of reference indicate corresponding parts throughout.
a is the receptacle for holding the bran into which the plates are first passed.
b is the second bran holding receptacle-the plates being reversed and passed
through in such reversed direction.
c is the top frame formed of channel iron or any other suitable material and
shape extending all round the top and holding the various parts together.
d is the outside plate or main frame of the machine which is carried on suitable
legs standards or otherwise suitably supported or mounted as desired.

page_text: e is the main axie carrying the sets of grippers in the first trough a.
is corresponding and separate axle over the second trough b.
is the bearing bolted or otherwise suitably mounted to the top frame e and
having cast or otherwise suitably formed integral therewith a cam g-or this cam gr
may if desired be formed and mounted independently of the bearings f
A similar bearing and cam g as above described only inverted is mounted in
such inverted position to the bottom edge of the top frame e so as thus to support
in such bearing the axle e in the desired position low down in the trough a.
is the worm shaft having worms thereon which latter in their turn impart
motion to the worm wheel 2 and thereby motion is independently and synchronously
imparted to the axle e and to the axle e respectively.
The worm shaft is rotated from any suitable source of power in any suitable
manner for instance as illustrated in Fig. 2 by means of a belt (not shown) which
drives the pulley on the shaft the bevel toothed wheel on the end of which
rotates the bevel toothed. wheel / on the said worm shaft h this shaft i and worm
shaft being each carried in bearings affixed to the side of the machine or
otherwise suitably mounted.
As the construction and operation of the plate gripping arms on the shafts e
and e respectively are identical and as each such arm on each such shaft is again
identical therefore it will only be necessary to describe one such arm and the parts
operating same in one set of grippers to this fully describe the whole.
I will therefore proceed to describe Fig. 4 as applied to the shafte it being
understood that such description applies equally to the grippers on shaft e as
above.
The shaft e carries suitably affixed thereto and so as to be revolved thereby a
rigid arm this arm; at its inner end in the case illustrated at Fig. 4. is shown
rivetted or bolted to a disc boss e* which in its turn is keyed or otherwise suitably
affixed to said shaft e all three such arms are shown radiating from said disc boss e*
and three such sets are shown arranged on each axle e and e respectively see Fig. 2
but it will be obvious that I may use other suitable numbers and arrangements of
these arms as may be found desirable or expedient.
kis the secondary arm carried in a slideway or guide on the primary arm.
This secondary arm at its inner end passes through a spring to one end.of which
it is attached and is then bent and passed round the transverse gripper operating
bar m (hereinafter described) and terminates in the turned up end ' against which
the said transverse bar operates while at its outer end this secondary rod terminates
in a turned over end or jaw which latter in combination with the turned over end
or jaw of the primary rod between them form the grippers for gripping the
plate as hereinafter described.
m is the aforesaid gripper-operating transverse bar. This transverse bar m
passes through the guideway provided for same in the three arms j in one. line
forming one set of grippers and a similar transverse bar m passes through each of
the other sets of three armsj forming the separate sets of grippers on the axle e-
each such bar m towards its outer ends being carried in guideways in the supporting
arms n (see Fig. 5) which latter are fixed to and carried round by the said axle e
these transverse bar supporting arms n are slotted or formed so that motion can be
imparted to m in a radial direction and each such arm n carries a spring o the
pressure of which can be adjusted by the set screw or equivalent device p whereby
when m is forced upwards (as hereinafter explained) such spring is .com-
pressed and returns m to its normal position when the upward pressure thereof.is
removed.
At or near the extreme outer ends of m is carried a small wheel which rides
against the aforesaid cam y so that as said radiating arms n carry round the
transverse bar.m thereby the wheel at each end of said bar m is caused to ride up
said cam g and thereby the bar m is forced outwardly against the pressure of. the
spring o until such wheel q is passed clear of the highest point of the camg.
whereupon the spring o forces back the transverse bar m and so on.
.I

page_text: The spring o thus normally keeps the jaws "open" by forcing the transverse
bar m against the end k¹ and thereby drawing inwards the secondary rod k and
thereby compressing the spring and while in this open position the plate to be
treated is dropped in between the jaws k² j and at this moment the cam g (which is
arranged and mounted in a suitable manner for the purpose) by reason of the
wheels riding up same force the transverse bar m outwardly and thereby release
the secondary rod k which in its turn is now controlled and forced outwardly with
the desired degree of pressure by this spring / so as to duly grip the plate between k²
and j³.
The cam g continues to keep the transverse bar m pressed outwardly for about
two-thirds of the entire revolution of the arm (Fig. 1) i.e. from the point where
the plate is fed to the grippers (see the arm Fig. 1) to the point where such arm
is in a vertical position at the top at which position or thereabouts the wheels q
ride off the larger part of the cam g and the springs o thereupon force the arm m
inwards and thereby draw down the secondary rod k and release the plate which
drops on to the slide or diagonal guideway Fig. 1 whence it slides into the next
set of grippers in the next trough where the cycle is repeated (with this difference
that the edge of the plate which first enters the bran in the trough a now enters
the bran last in the trough 6) the plate after passing through the trough 6 being
similarly released and dropping upon the diagonal table or guide rods s which shoot
or drop said plate clear of the branning machine into or on to any suitable receptacle.
The feeding arrangement shown in the drawings is as follows:-
(Fig. 1) is an open-work frame or rest (for instance like a gridiron or like the
desk part of a music stand) which rest t forms the feed table and same is pivotted
or mounted at its upper end so as to be free to turn on the axis 1.
is a rigid arm or lever rigidly fixed to the axis u carrying this tablet or other-
wise suitably and rigidly connected to t so that any movement imparted to vis
thereby imparted to t-both turning on the point u.
The free end of vis bent downwardly or otherwise suitably curved or formed so
as to interpose in the path of travel of a three-armed striking device w. This
device w being rigidly mounted upon and revolved by the axle e so that in the
rotation of w each arm thereof as it comes round in turn strikes the end v' of the
lever and thereby raises the rest t clear of the stops as shown in Fig. 1 and
the plate to be fed into the machine (which was resting on t-with its lower edge
supported by the stops a projecting through t) upon said rest t being thus raised
clear of the stops thereupon the said plate is free to slide down the rest t into the
gripper jaws which at such moment have just arrived beneath the lower edge
of t and are 66
open" ready to receive the plate thus fed into them and as the arm j
continues to travel the said gripper jaws close upon and firmly grip the plate, the
arm w passes clear of the end of the lever which thereupon drops, the rest tis
thereby moved down so that the stops a now protrude through this rest t to form a
support for the next plate which is placed upon the rest t and held by the stops
until the rest t is again moved by the action of the arm w so as to allow the said
plate to slip off as before described and so on.
Referring to Fig. 2 :—
V
If desired I may connect the three or other number of gripper arms jj forming
each set of grippers for gripping one plate by means of a transverse rod or bar
affixed to the inside of and such rod being of the full width of the trough a or b
.or of a less width than same if desired-but advantageously of rather more width
than the widest plate to be put through the machine.
A corresponding transverse bar would be affixed to each gripper jaw in the
same set of grippers and thus the plate would be gripped along the whole length of
its edge between the said transverse bar carried on and the second transverse bar
carried on thus if the plate be of a greater width than the outside gripper
arms then these said transverse bars will form a kind of prolonged lip or extended
gripping surfaces which will completely cover the whole width of the plate along
its edge where same is gripped.
