Improvements in Machines for Making the Bodies of Sheet Metal
Cans and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 machines for making sheet metal can bodies.
:
The machine or apparatus embodying the invention, as shown in the accompanying
drawings forming a part of this Specification, is designed to perform automatically
the following successive steps, viz. To feed the sheet metal blanks from which the
can bodies are to be formed one by one from the pile or stack of blanks; trim the
edges which are to be folded together of the blanks; produce the requisite panels
or corrugations required in the sides of the can body; form edge folds or hooks at
the meeting edges of the blank; form up or shape the blank into a can body
and interlock the edge folds or hooks to make the side seam; close or squeeze the
folds of the side seam together; and solder the side seam.
The machine shown in the drawing is one specially designed for making the
bodies of large square cans, such as are commonly used for shipping petroleum.

folding or hook forming dies or devices. K, Kare the paneling dies or devices.
L, Lare edge trimning dies or devices. M, N, is the reciprocating blank carrier
consisting, preferably, of parallel bars furnished with spring pawis m by which
the blanks are pushed or fed forward to the paneling and trimming dies, to the

page_text: edge folding or hook forming dies, to the horn, and the can body discharged
from the horn. P is the blank holder in which a pile or stack X of can
body blanks are placed and from which they are fed one by one by a feeder R
operating in conjunction with a movable safeguard or separator device S. T is
a blank adjusting device which receives the blanks as they are delivered from
the feeder R and moves or adjusts them against a gage Ú in proper position
to be moved forward by the reciprocating blank carrier M, N. B is a flexible
can body carrier for conveying the can bodies along the track (i", G", G",
over the side seam fluxing bath E2 and solder bath F and against the inside
wiper H and the outside wiper M" by which the surplus solder is removed
from the seam both from the inside of the can body and from the outside thereof.
A track Do supports the flexible can body carrier B.
In operation the blanks rare fed, one by one, from the pile of blanks X by
the feeder R and delivered onto the blank adjusting device T which moves the
sheet lengthwise until one of its end edges abuts against the guide U and then
a reciprocating blank carrier M moves the blank forward horizontally in a
direction at right angles to its former movement into position between the edge
trimming dies L' and the paneling dies K K', where the edges of the blank
are trimmed and the panels, required in the completed can body, formed therein.
The part M of the feeder then moves the blank forward in position to be operated
upon by the edge folding dies G, G' and H, H', H³. The blank carrier M then
moves the blank forward over the horn B, it being at this time supported by
the movable guides or supports D D. The folder then folds or laps the blank
downward around the horn and interlocks its hooks .r. The scam closer or
squeezing device E then moves upward and closes the seam against the horn.
The reciprocating blank carrier or feeder N then pushes the can body off of
the horn onto the feed table extension G of the can body track Go in position
to be caught or engaged by the carrier Bo which then conveys or slides the
can body along over the fluxing bath E20 by which the side seam is brought into
contact with the liquid flux in the bath. The carrier B20 then moves the can
body along over the molten solder bath F20 thus soldering the side seam; and
then conveys the can body along said track G20 against the outside brush or
wiper device M", the upper guide M at this time holding the can body down
against the wiper. The carrier B then moves the can body along into position for
being operated upon by the inside wiper H, after which the finished can body
is discharged from the machine down the inclined chute G".
As the blank is moved toward the reciprocating carrier M, it is held flat
down upon the carrier bars by guide or pressure bars V.
In describing in detail the several operative devices herein before described
generally, it will be of convenience to take them up in the order of their operation
upon the blank from which the can body is to be formed, and the first as to the
blank holder P and feeder mechanism R and S.
By referring more particularly to Figures 2, 9, 14, 15, 16 and 17 it will be seen
that the blank holder P consists of an inclined rack or box adapted to receive
and hold the pile or stack X of blanks on their edges and in an inclined position.
The lowermost corner of the pile of blanks rests upon a projecting lip, and
the opposite upper edge of the pile of blanks rests upon a projecting lip or
ledge p'. The blauk holder P is also furnished with a slotted saleguard device
or separator S, the slots of which is substantially equal in width to the thickness
of the blank, so that only one blank can be lifted or slipped by the feeder R
over the edge of the lip p so as to disengage it from the pile of blanks. The
lower edge X of the pile of blanks X abuts against or rests upon the inclined
side or guide bar P of the holder P. The inclined side or guide bar Pis
furnished with an adjustable section or member P pivoted at P³ and fixed in
place by an adjusting screw P4, so that its inclination may be adjusted or
regulated as required to cause the pile of sheets to properly slip or feed down
by gravity as one after another is removed from the bottom of the pile by the

page_text: feeder R. The upper edge or face X' of the pile of blanks may abut against
an incline guide P, which is furnished with a projecting lip or ledge p which
serves to separate or divide the pile of blanks into two parts and thus relieve
the feeding device R and separating device S from the pressure of the whole pile.
This division of the pile into two parts is also of service in relieving the
devices R and S from any extra strain or blows when the attendant or operator
adds a package of new blanks to the pile already in the holder, and it also serves
to indicate to the attendant when a new supply of blanks should be added. The
blanks slip, one by one, or a very few at a time over the projecting lip or ledge
as the blanks are fed by the feeder R, by reason of the double inclination that the
guide or side P¹ has. In other words as soon as the blank slips a certain
distance down the more inclined part P of the guide P¹ the blank becomes too
short to rest upon the lip or ledge and then of course drops from the upper
part of the pile to the lower part thereof.
The feeder R consists of a block furnished with a shoulder r, which projects
from the face of the feeder block about the thickness of one of the blanks, so as to
engage the lowermost blank of the pile and shift or slip it upwards into the slot s
of the safeguard or separator device S and thus disengage it from the lip of the
holder P. The feeder has two movements, one a sliding or reciprocating move-
ment to slip the blank into the slots of the separator S and disengage the lower
edge of the blank from the lip p; and the other a swinging or lateral movement to
permit the blank to drop down upon the conveyor or carrier M or adjusting
device T. To provide for this double movement of the feeder it is mounted to slide
in a pivoted or swinging guide R'.
The required sliding or reciprocating movement is imparted to the feeder by a
cam R³, connecting link R, lever or armed rock shaft R' and connecting link R³.
The required pivotal or swinging movement is communicated to the feeder R or its
guide R by means of an arm R' thereon, connecting link R8, lever or armed rock
shaft R, connecting link R¹º and cam R".
The separator or safeguard device S is preferably pivotally connected at sto
cross bar P' of the holder, and furnished with a spring &, so that the slot of this
safeguard may be kept in proper position in relation to the edge of the sheet in case
the edge of the sheet should be buckled or out of a straight line.
Connected to the lever R' of the feeder R by an arm and link and
reciprocating in suitable guides on the cross bar P is a slide S' which carries an
extractor S which serves to push the sheet out of the slots of the separator or safe-
guard device S, in case the blank should tend to stick therein. This extractor S²
preferably has a yielding connection with the slide S¹, the same being effected by
means of a spring S³. The slide S' is also furnished with a shouldered lip or
projection S* adapted to fit under the pile of blanks and serving in part to guide
or support the same.
As the blanks are delivered one by one from the holler P by the feeder R, they
fall upon or over the reciprocating carrier bars M by which the blanks are carried
or conveyed to the paneling and edge trimming dies, thence to the edge folding or
book forming dies, and thence to the horn. But to adjust the blank transversely
on the carrier M, a blank adjusting device T consisting preferably of a series of
parallel revolving rollers, arranged parallel to and on a level with or slightly above
the carrier bars M, is provided, and which serves to move the blank until its edge ³
abuts against the gage or guide U. Any other equivalent form of blank adjusting
device may of course be used in place of the horizontal set of rollers T, but it is
preferable to employ the rollers as a means of adjusting the sheet in position
transversely on the carrier bars M, as the parallel rollers leave a free space
between them for the cu-acting carrier bars M, and as they afford a broad platform
to properly support the blank throughout its length. The construction of this
adjusting device T will be readily understood by reference to Figures 2, 3 and 12.
Motion is communicated to the rollers, preferably, from the counter shaft T
through the bevel gears T2, T3, pulleys T and belts T%, and the intermeshing

page_text: gears T which connect the individual rollers. The blank conveyor bars Mare,
preferably, two in number, and reciprocate in suitable guides on the frame of the
machine. The pawls m of the carrier bars are best shown at Figures 12, 28, 29.
30 and 31. They are adapted to engage the back edge of each blank and push it
forward before them, and shut or close down within the carrier bar so as to ride
under the next succeeding blank. The pawls m are pivoted at m' to the carrier
bars M and N in recesses m² therein, and are held in position by springs m³. Each
pawl is furnished with a projecting lip m which engages the wall of the recess m²
and thus prevents the pawl from being thrown too far out by the spring m. The
carrier bars M are secured to or carried by, or formed integral with, a reciprocating
cross head or slide M2 which moves back and forth in suitable guides M³ on the
frame and is operated from the main crank shaft W by a crank W thereon, which
actuates a reciprocating slide M which slides in the slotted lever Ms, pivoted at M
to the frame of the machine, and to which is pivotally connected a link M' which
operates a lever M8 pivoted at M' to the frame and connected by a pivoted link M™
with the cross head M².
These
To ensure the pawl m properly engaging the blank, pusher bars M are provided
which are held retracted by springs M2 and which serve to push the blank slightly
forward on the rollers T, so that pawls m will be sure to be brought back of the
back edge of the blank before the carrier M begins its forward movement.
pushers M are pushed forward by the feeder bars M as they make their retracting
movement by the pin or projection m³ thereon engaging a lever me pivoted to a
bracket in and the opposite end of which strikes against the spring pins or
bar M
By the forward movement of the carrier bars M the blank is pushed or conveyed
forward into position between the edge trimming dies L L, and the paneling
dies K K', the blank at this time being smoothed and held down on the carrier
bars M by the spring pressure guide bars V, which are supported on brackets or
bridges V, (attached to the frame of the machine) by means of adjustable bolts V*
and springs V. The pressure bars V are furnished with longitudinal grooves or
channels for the pawls m of the carrier bars M.

The edge trimming dies L L consist, preferably, of a pair of knives or dies
affixed to the bed L2, and a pair of movable knives or dies affixed to the vertical
reciprocating cross head L³. These trimming dies serve to square and straighten
the edge of the blank and make the blank of the exact length to form the can body,
so that the can bodies will all be of a uniform size, and so that the edges of the
blank will properly register with the edge folding or hook forming dies at the
succeeding step or operation.
The paneling dies K K' likewise consist of a bed die secured to the bed L' and
a movable die attached to the same cross head L³ which carries the trimming die.
The trimming and paneling dies are best shown at Figures 7 and 11.
The paneling dies are furnished with longitudinal grooves k to receive the feeder
or carrier bars M, and with longitudinal grooves k' to receive the pressure or guide
bars V.
The cross head L³ which carries the movable paneling and trimming dies is
operated from the crank shafts L by means of the connecting links L. The
links L are made in two adjustable or screw connected parts for purposes of
adjustment.
After the blank has thus been trimmed and paneled it is next moved forward by the
second pair of pawls m on the feeding bars M to the edge folding or hook forming
dies G G and H, H', H2. These dies are best shown at Figures 8, 11, 23, 24
and 25. The dies G G which form a groove shaped hook or edge fold ², consist
of a female die G secured to the bed G and a male die G secured to a movable
cross head G³. The bed G2 and cross head G³are furnished with counterparts G* G*
of the paneling dies K K', so as to properly fit and support the paneled blank
during the edge folding or hook forming operation, the same serving simply as
holding or clamping plates for the blank. These holding or clamping plates G³ G

page_text: are furnished with grooves gg for the feeder bars M and presser bars V. The
edge folder or hook forming die H, H', H2, for the opposite edge of the blank, and
which serves to make a fold shape turned hook e', as clearly shown in Figure 24,
consists in part of the die H, secured to the bed G2, and furnished with a horizontal
lip or ledge h around which the edge of the sheet is folded to form the hook. It
further comprises a movable folding die II secured to the cross head G and which
serves to make a substantially right angle bend at the edge of the blank. It
further comprises a horizontal folder 112, which is adapted to slide in suitable
guides H3 on the cross head G2. The guide H³ along which the folder H' slides
or reciprocates, is arranged with its guide face in an inclined position, so that the
downward movement of the cross head G³ will serve to give the required inward or
horizontal movement to this folder H2, when the face or end h¹ of the folder H²
strikes against the stop 2 secured to the bed G². The folder H is held in its
retracted position by a spring ³; an adjusting screw *, carried by a bracket h³,
serves to limit the retracted movement of the folder II. H' is a guide for the
edge of the blank to abut against, it is mounted yieldingly on suitable guides or
pins Hattached to the bed plate G2, and it is held in position by a spring H. As the
cross head G³ descends this guide His pushed down out of the way by the folder H
striking against the same. The cross head G³ is operated by suitable cranks G' on
the crank shafts L', the same being connected with the cross head G³ by the pivoted
links GB.
After the edge folds or hooks ¹² have thus been formed in the blank it is
moved forward by the third pair of pawls m on the feeder bars M into position over
the horn B, the edge of the blank at this time abutting against and being guided
by the side guides Y Y and supported by the horizontal or movable guides D D
which are adapted to reciprocate transversely in suitable guides D' on the frame of
the machine. These guides D are preferably held in position to support the edge
of the sheet by springs D2, adjusting screws D³ being provided to regulate the
tension of the springs. The movable guides D are, preferably, retracted, (to
permit the blank to be folded downward around the horn by the folder C) by means
of vertically reciprocating bars or wedges D', which pass through slots d on the
guides D and which are furnished with inclines or projections to engage the
guides D. These bars or wedges D' are, preferably, secured to and operated by
the same cross head C³ which actuates the folder C.
The horn B is of square form, as the can bodies designed to be formed by this
particular machine are square in cross section, but the shape of the horn will of
course conform to the shape of the can body desired to be made. The horn is,
preferably, of skeleton form so that it may chiefly support the can body at the four
corners thereof. The construction of the horn and the mechanism for folding the
can body blank around the horn, is shown in Figures 1, 4, 5, 6, 10, 11, 18, 19, 20,
21 and 22.
The horn B preferably has two fixed corners or die pieces 6b of steel at its
side corners, and two movable opening and closing or expansible corners &₁ b²,
the same being opened and closed by a slide & connected therewith by pivoted
links b³. The slide is reciprocated in the horn so as to open and close the
movable portions of the horn by means of a crank arm on the rock
shaft, and which crank arm is connected by a pivoted link with the slide bº.
The movable portions of the horn are forced apart or expanded after the
blank has been folded around the horn and its hooks . brought into position
for interlocking. The expanding movement of these portions of the horn serves
to bring the hooks into register with each other and to properly support the seam
while it is being squeezed by the buner E; and the contracting movement of
such portions of the horn serves to loosen the formed can body on the horn
so that the carrier bars N may readily push the can body lengthwise off
the horn.
The horn B is further preferably provided with movable or hinged wings or
leaves B B', pivoted at B to the upper corner of the horn and adapted to be closed

page_text: down against the periphery of the horn by the blank as it is folded around the
horu. These pivoted wings or leaves are normally held up in the position, as
indicated in Figures and 6, by light springs B³ surrounding the pivoted steins B.
These yielding or spring supported wings or leaves serve to partially sustain the
blank and in a measure to smooth it out as it is being carried downward around
the horn by the folder C. When the folder C has been retracted these spring
leaves also serve, in a measure, to loosen the can body on the horn, and to prevent
any tendency of it sticking thereon. The horn B is secured rigidly at one end to
the frame of the machine.
The folder C is, preferably, furnished with two hinged arms C' C adapted to
close together around the horn. The folder is carried by or secured to a
vertically reciprocating cross head C³. The pivoted or hinged arms "C" of the
folder are pivoted to the folder by pivots c which register with the side corners of
the horn when the arms C C are closed around the horn. The arms C¹ Care
each preferably made in two sections or parts, jointed or clamped together by a
yielding or spring held clamp or joint, bolte and spring c. The purpose of
this is to relieve the arms C C and the connecting mechanism of undue strain in
case of accident, and compensate for inequalities or differences in thickness of the
stock from which the blanks are cut. The horn B is further provided with slots.
grooves or openings for the carrier bars N N to reciprocate in. These slots
or ways for the carrier bars are, preferably, located at the lower half of the periphery
of the horn. The folder C is further provided with a clamping bar C, the under
face of which conforms to the upper corner of the horn. The clamping bar is
independently movable ou the former C or its cross head, so that this clamp bar
may come down first and clamp and hold the blank at its middle against the upper
part of the horn before and while it is being folded downward around the horn.
by the former or folder C. The clamp bar C is also so timed in respect to the
movable guides D D for the edges of the blank, that it will clamp the blank at its
middle before the guides D D are withdrawn. The blank is thus always adequately
held in position over the horn, either by the side guides D or the clamp bar C', one
or both. The movable arms CC² of the folder are closed about the horn, (the
arm being so timed as to close slightly before the arm C, so that the hook ...¹
will come to place first and underneath, and the book last and overlapping the
hook,) by means of the vertically reciprocating racks C³, meshing with the
loose gears C, which gear carries a pin that engages a gear or disc C³ fast
upon the shaft C, which constitutes the pivot of the swinging arm C or C
These swinging arms C Care retracted by spring actuated racks C which engage
the teeth of the gear C. The spring C for actuating the racks C is enclosed
in the guide C for the rack C10 C13 is a supplemental spring barrel connected
by a chain C to the armi C' or C to assist in, or better to insure, the proper
retraction of these arms. To prevent danger of breakage or undue strain of the
parts by accidents or undue thickness or irregularities in the blanks, the racks C
are held in place or engagement with the gears C' by spring held cap plates C³,
which are attached to the guide C of these racks. C are the springs for
holding these caps in place. The cross head C³ is actuated by cranks C C7
on the crank shafts which operate the cross heads that carry the trimming,
paneling and edge folding dies. The crank shafts are operated from the
main crank shaft W by a crank W2 thereon, which is connected by a link W³,
pivoted at its lower end to a supplemental cross head Z having bearings in
the cross head C³, and which cross head Z is connected by links Z' with the crank C.
The rack bars are operated by the cross head Z to which they are
attached. The links Z' are so arranged in respect to the crank arms C and
the cross head Z as to permit the cross head Zaud the rack bars C26 carried
thereby to have a further downward movement after the cross head C and the
folder C carried thereby reach home, thus causing the arms C1 C2 of the folder
This
to close about the horn after the folder C stops its downward movement.
further movement is permitted as the link Z' passes its dead center.
This also.

heads.
The clamp bar C is operated, as before described, by means of a pair of levers
or rock shafts C, connected by links C with said clamp bar, and connected
together by a pivoted link C and one of which is operated by a cam C2 on the
main crank shaft W, lever C, and link C25.
The bumper E is secured to a cross head E' and is reciprocated vertically in
suitable guides E2 on the frame by means of a connecting link E³, rock shaft E,

cross head M2 by the adjusting screws n.
The portion of the frame A. which supports the side seam soldering mechanism
of the machine, preferably consists of a series of double or U-shaped standards
or posts connected together by suitable cross bars or webs A', and connected
together in the direction of the length of the machine by the rods or tubes A²,
and also by the tracks D for the carrier, and the tracks Go for the can bodies
and by the flux and solder containing vessels E and F, or their supports.
The carrier B20 for the can bodies consists, preferably of two flexible link
chains connected together by cross bars 617 617 at intervals. The flexible
carrier 1320 extends around and is driven by the pulleys or wheels C3, the
shafts C of which are journaled in suitable bearings C on the frame of the
machine. The cross bars 17 of the chain carrier are furnished at either end with
anti-friction wheels or rollers 2 which travel upon the tracks D. The wheels or
rollers are furnished with langes 32 to guide the carrier on the track Dan.
There is one line of tracks D for the upper loop of the chain and another similar
line for the lower loop. The tracks D are secured and supported by suitable
brackets attached to the upright standards of the frame at the inside thereof,
as is clearly indicated in Figure 41. The fluxing bath or device E20 and solder
bath or device F are located below the lowermost loop of the chain carrier 120.
Go is the device for supporting the cans as they are moved along by the can
carrier or conveyor. This can supporting device is, preferably, not located on the
carrier as it makes a better as well as a more economical construction to fix it
stationary to the frame; the same being, preferably, a continuous track along
which the can bodies may slide. As illustrated in the drawing, it consists of two
rails, one on each side of the can body, and the track rails G are secured to and
supported by suitable brackets G attached to the vertical standards of the frame.
The spaces B10 in the carrier between the cross bars 17, constitute the pockets or
receptacles in the carrier for the cans. These can pockets or receptacles B are
made considerably longer than the can bodies to be operated upon and preferably
about twice the length of the can body, which is ordinarily or chiefly designed to
be soldered in the machine. By providing the can carriers thus with pockets or
receptacles B10 materially longer than the can bodies, a simple provision is thus
made for permitting the can bodies to be thus moved forward or along in respect
to the carrier while the carrier is in motion.
The track G upon which the can bodies ride, is furnished with an extension
or feed table G extending under the wheel or pulley around which the chain
passes, so that when a can body is placed either by hand or automatically upon this
feed table or extension G the cross bar 67 which forms the end of the can
pocket B in the carrier, will, as it passes around the pulley, engage the rearmost
end of the can body, and thus automatically itself feed or push the can body from
the feed table into the machine. The continuous track G, upon which the can

page_text: bodies rest, is furnished with a wilened or depressed portion 10 to permit the can
body to come in contact with the flux, and a similar widened or depressed
portion to permit the can body to come in contact with the molten solder in
the vessel F. The solder vessel F20 has a longitu linal slut or opening f10 to
receive the seam of the can. And it is further provided with an outer or metallic
shell which forms with the half shell F a flame chamber F surrounding the
solder vessel F at its bottom and sides. The heat chamber F is preferably
heated by gas supplied through the burners F³ and pipes F.
The can supporting track G is provided with a jog or depression G³, which
permits the can body to drop down below its ordinary level to enable the
reciprocating wiper II to enter inside the can body. The wiper H consists,
preferably, of a brush or pad of asbestos or other suitable material attached to a
holder pivoted to a slide or cross head H2, which reciprocates in suitable
guides H on the frame of the machine. The pivoted holder H of the wiper
has a roller or guide arm which works in a suitable guide on the frame to

slide or cross head H22 is operated by a lever pivoted at 30 to the frame of the
machine, or to a bracket secured thereto, and having a short arm which projects
in the path of the cross bar of the can carrier 130, and is engaged and operated
thereby. The long arm of said operating lever is connected to the wiper slide
through the pivoted links. The wiper slide is returned to position by a
second lever 470, which is pivoted at 180 to the frame, the short arm of which is
likewise engaged by one of the cross bars 7 on the carrier B. The long arm
of the lever is pivoted to the connecting link 50.

To move the can body to the forward end of its pocket B of the carrier prior
to the commencement of the wiping operation, so that the wiping operation may
take place in part while, or be continued until, the rear end of the pocket B" again
overtakes the can body, means are provided for pushing or moving the can body
to the forward end of its pocket at this time. The means or mechanism employed
for moving the can body to the forward end of its pocket in the carrier inay he of
any suitable form or construction; and its form and construction may be greatly
varied by skilled mechanics, as well as the means for operating the reciprocating
siper. The particular means which has however heretofore been generally
employed for moving the can body forward in its pocket consists simply of a
movable slide Ko furnished with a pivoted finger or pawl to engage the rear
end of the can body and push it forward in the pocket of the carrier as the carrier
moves along. The pivoted or yielding finger permits the can body to pass the
finger. This can body moving slide or device is preferably duplicated on each side
of the machine so as to engage both sides of the can at the end thereof. It is
preferably given the necessary quick movement by a lever 10 pivoted to the
frame at and the short arm of which is engaged by the cross bar 6 of the
carrier 120. The long arm of this lever is connected to the slide K20 by pivoted
links. A second lever pivoted at 4³ to the frame, and operated by the
carrier B engaging its short aim 80 serves to return the slide K to place.
Upper guides 1.20 serve to keep the can bodies properly in contact with the
molten solder as they pass over the solder bath F.
An upper guide M20 serves to hold the can bodies properly in contact with the
outside wiper M", at the incline M in the tracks for the carrier and for the cans.
The exterior wipers M" are secured to or carried by pivoted arms or levers ni
furnished with weights m to press the wipers against the seam.
Beyond the inside reciprocating wiper H20 is provided a set of external wipers N,
the same being carried by pivoted arms no having weights 10, the can bodies being
held in contact with these wipers by a guide or holding device N" above the cans
and preferably secured to the stationary frame of the inachine.
By this improvement it will be observed that the can body during the wiping
operation, or a portion thereof, is so to speak, moving backward in respect to the
carrier or from the front end to the rear end of its pocket in the carrier; or in
B

page_text: other words the can remains, or may remain, stationary in respect to the frame of
the machine during the interval that the carrier moves forward about the length
of the can body.
The jog, shoulder, or depression G30 in the can track G is so located or con-
structed in relation to the reciprocating wiper and to the reciprocating device for
moving the can bodies on or along the carrier that the can body will drop or
enter this depression as soon as it is moved to the front end of its porket B20 in the
carrier, and thus be in position for the reciprocating wiper to enter the can body.
The track G upon which the can bedies rest or slide is also provided with an
inclined delivery chute or extension G into or onto which the can bodies are
automatically discharged or delivered by action of the flexible carrier B as it turns
or travels around the pulley at the rear or delivery end of the machine.
The machine hereinbefore described for automatically feeding the can bodies
into the machine involves the use of pulleys for the chain carrier 1320, consisting
of two separate rings or wheels with an open space between them for the admission
of the can bodies: that is to say the pulley shaft has fixed to it two rims or
wheels C30 C30, one for each of the chains 1320. The wheels Care, preferably,
not polygonal but circular, and the links of each of the chains B are short and the
number of them employed, for example ten, between each pair of cross bars 6",
as is clearly indicated in the drawing.
By thus employing round pulley wheels C, in connection with short link
chains furnished with cross bars 7 at intervals to constitute the pockets or
receptacles for the can bodies, and by furnishing the cross bars with anti-friction
rollers or wheels to travel on the tracks, the injurious effects due to the more or
less jerky motion imparted to the cans, by employing a carrier chain having long
links and polygonal wheels is entirely overcome or prevented during the soldering
operation. By this construction of the can carrier the can bodies are conveyed
through the solder bath in an easy, uniform and steady manner, conducing to the
production of the best results, at the same time less power is required to run the
machine and its durability increased.
The soider bath or vessel F20 is furnished with an inclined center bar or
track F Fig. 2 for the angle or nose of the can to ride against at the inclined
portion G of the track G, where the can rises out of the solder bath. This
inclined center bar or track F extends down into the solder and is heated thereby
and also by burners or gas jets F placed beneath the same to prevent the con-
gealing of the surplus solder before it has time to How out of the can. The
inclined center bar or track F is a simple bar of metal fixedly attached to the
frame in position to engage the seam or corner of the can and assist in tilting it
and raising it out of the solder bath as the can is moved along by the carrier. This
heated bar of metal also assists somewhat in preventing the surplus solder from
congealing before the can reaches the wiping devices.
The solder bath F20 and the flux bath E also are mounted on adjusting
screws F Fig. 2 to enable the level of these vessels to be properly and
conveniently adjusted.
The pulleys C30 are preferably formed with projections or notches to engage
the bar to ensure the proper and regular movement of the chain carrier. One
of the pulleys or sprockets C is mounted on a cross slide C³ which is held in
position against the tension of the chain carrier by a weight C suspended by a
line (attached to the cross head Co which passes over the pulley C.
The inclined solder feed tubes F" Fig. 41 feed the solder into the solder
chamber F at the widened or reservoir portion of the same near one end of said
trough or vessel F
