PROVISIONAL SPECIFICATION,
Improvements in the Manufacture of Sheet Metal Cans.
I, ROBERT EDWARD PHILLIPS, Assoc. M. Inst. C.E., M.I. Mech. E., of 70, Chancery
Lane, in the Parish of St. Andrew's, Holborn, in the County of Middlesex, Consulting
Engineer and Patent Agent, do hereby declare the nature of this invention, which
has been communicated to me from abroad by Olin Stephen Fellows, of Middle-
town, Orange County, in the State of New York, U.S.A., Manufacturer, to be as
follows-
My invention relates to the manufacture of sheet metal cans in which the end
plates are soldered to the cylindrical bodies by passing the edges of the can over and
in contact with molten solder according to this method.
The edges of the cans take up and carry away an excess of solder which is
objectionable, not only on account of the waste of solder, but also because the
unnecessary solder detracts from the symmetrical appearance of the can. I provide
for the removal of the superfluous solder by the use of a brush used in connection
with mechanism for rotating the cans continuously and simultaneously after they
leave the soldering bath, the brush being used either alone or in connection with
mechanism for throwing off the main excess of solder by centrifugal force as a
preliminary to the finishing operation performed by the brush. The brush in either
case tends to force the melted solder into the annular joint as well as to remove all
external solder, imparting to the edge of the can a finished or polished effect not
attainable by the use of centrifugal force alone. The action of the brush is forcibly
sweeping some of the solder into the joint while wiping off all excess is of special
importance at the junction of the annular joint with the longitudinal body joint or
seam at which point there is greater tendency to leakage owing to the overlapping of
the edges of the can body.
I am aware that it has been proposed to use circular buffers or brushes to remove
superfluous solder from cans held and treated individually; I am also aware that it
has been proposed to treat cans held and rotated individually to the action of an
endless wiper belt; but neither of these ideas anticipates my invention, the
distinguishing feature of which consists in treating the cans as they leave the
soldering bath to mechanism by which they will be rotated continuously and simul-
taneously for the removal of superfluous solder substantially as hereinafter claimed,
thus insuring the removal of the excess of melted solder and the finishing or
polishing of the edges of the can without interfering with or retarding the continuous
flow or delivery of the cans from the soldering bath. This feature of treating the
cans for the removal of solder succesively and collectively in a continuous procession
without intermission is important in the manufacture of cans in large quantities, and
I am the first to devise and invent mechanism for the removal of superfluous solder
from the cans under such conditions as contra-distinguished to the treatment of cans
specially and individually as heretofore. Thus, the saving in complication of cost
of mechanism, as well as in time, renders my method of continuous treatment of
practical utility and value under the requirements at present prevailing in the
manufacture of sheet metals cans in large quantities for industrial purposes, a result

page_text: not heretofore attained in the attempts to remove superfluous solder from the
cans.
In the accompanying drawings, Figures 1 and 2. are respectively a plan and
elevation of apparatus suitable for carrying my invention into effect; while Figure 3
is a transverse section upon plane of line 3, 3, Figure 1.

Throughout the views similar parts are marked with like letters of reference.
Standards S, support the several shafts 1, 2, 3, 4, 5, and 6 and 7. The power
pulley 8 is secured to the shaft 1 upon which is also mounted the transmitting
pulley 9, by which power is transmitted by means of the belt 10 to the pulley 11 on
shaft 7, said pulley 11 being of greater diameter than the pulley 9. Pulleys 12, 13, 1
14 and 15 support an endless belt B while the pulleys 16, 17 and 18 support a similar
belt C, the opposed surfaces of which belts receive and act upon the cans from the
rails r,, extending from the soldering machine.
It will be seen that the adjoining and opposed surfaces of the belts B, C, travel
in opposite directions, as indicated by the arrows, and at different speeds, the 1
upper one B, faster than the lower, so that cans fed in between the belts by the
rails r, r, will be rotated upon their longitudinal axes and finally discharged on to
the rails 8, 8, at the opposite end of the device.
g, g, are guard rails which preserve the alignment of the cans throughout their
journey. 19 is a spring which tends to press the cans up against the underside of
the belt b and thereby insure their entrance between both belts.
The upper
shafts 1, 2, 3, 4, are adjustable vertically for the purpose of regulating accurately
the relative positions of the belts to conform to the requirements of the cans under
treatment. The pulleys 13, 14 and 17 are idlers.
Upon the shafts 2, 4, are mounted smaller pulleys 20, 21, supporting the endless
brush belt L. The pulley 22, is an idler. Pulleys 23, 24 on the shafts 2 and 4 are
connected by a cross belt D, by which power is transmitted from the shaft 4, to the
shaft 2, causing it and the pulley 23, to rotate in the opposite direction to that of
the shaft 4, and thereby imparting motion to the brush belt L, in a direction
opposite to that of the belt B.
It will be seen by reference to Figure 3 that the belts B, C, bear upon the
cylindrical bodies of the cans while the brush belt L, is so situated that it bears
against the ends or edges of the cans which have passed through the soldering
bath.
The rails 8, 8, extend under the brush L, parallel to the upper side of the belt C,
but slightly below the upper surface of the latter the object being to sustain the cans
against depression under the action of the brush belt.
In operation the cans from the soldering machine are grasped by and between the
belts B, C, by which they are rotated upon their longitudinal axes and gradually pass
to the discharging rails s, 8, in the meantime having their soldered edges subjected to
the action of the brush belt L, which removes all superfluous solder at the same time
positively forcing solder into or against the edges of the joints and cleaning and
polishing the edges of the cans. The solder thrown off by the brush is collected
and re-melted for use.
The brush instead of being an endless belt may consist of a stationary brush
of suitable length against which the cans may be rotated as described, but the
travelling endless brush is preferable as it affords a greater amount of contact within
a given space.
In some cases, as where the exterior flanges of the end plate of the cans are wide,
owing to the depth to which the edges of the cans are necessarily submerged
therein in order to bring the edges of the end plate flanges below the surface of
the solder bath, the end plates take up and carry away an amount of solder that
is entirely useless, and which is not reached nor removed by the brush belt, that
so effectually cleans and polishes the flanges and lower parts of the can body;
while on the other hand the use of centrifugal force, as set forth in my concurrent
application filed herewith, while it impels the solder taken up by the end plates
to the edges thereof, and throws off most of it, it is still apt to leave residual

page_text: ridges on the edges of the can, and does not remove the solder from the cap
flanges and can body as perfectly as does the brush, for the reason that the surfaces
of the flange and of the can body are at right angles to the plane in which centrifugal
force acts, whereas the end plates coincide substantially with said centrifugal force.
Hence, the centrifugal force may be safely relied upon to drive off the greater
portion of the excess of solder from the end plates and to carry the remainder to or
over the edges of the caus from whence it may be removed positively by the brush
belt.
It will thus be seen that by the use of centrifugal force alone, while I obtain clean
end plates, I am not able to clean the flanges and adjoining portions of the can bodies
as effectually as is sometimes desirable, whereas, by the use of the brush alone, the.
end plates retain most of the superfluous solder taken up by them. I have,
therefore, devised a modification of my apparatus in which the superfluous solder is
removed by the combined action of centrifugal force and of a brush, the centrifugal
action throwing off most of the superfluous solder, especially from the end plates
and collecting the remainder in the most advantageous position for removal by the
brush as hereinafter stated.
This modification is illustrated in Figures 4, by reference to which it will be seen
that the apparatus used is essentially the same, the only difference being that the
beit L, is much shorter and passes over a pulley 13, rigidly attached to the shaft 2,
the cross belt D, in this case extending from a pulley 24 on the power shaft 1, directly
to a pulley 23, on the intermediate shaft 2, so that the brush belt L, though shorter
moves in the same direction and under the same conditions as hereinbefore
described.
In operation the cans from the soldering machine are grasped by and between the
belts B, C, by which they are rotated upon their longitudinal axes with sufficient
velocity to throw off by centrifugal force the main portion of the superfluous
solder adhering to the exterior edges of the can, while at the same time they are
gradually passed towards the endless brush belt L. The distance and speed are so
timed as to effect the displacement of the superfluous solder from the end plates, or
for its collection upon the edges of the flanges, before the endless brush belt is
encountered, so that the latter, travelling as it does in a direction opposite to that in
which the cans rotate, will sweep off all remaining superfluous solder and impart
a finished appearance to the edges of the cans.
It is to be understood that in using the word "brush" herein I do not confine
myself to any special structure thereof, since any, equivalent of an elastic or resilient
bristle, wires, scrapers, may be substituted for the removal of superfluous solder with
like result; neither do I confine myself to any exact form and arrangement or brush
with relation to the other parts of the apparatus.
Thus in Figures 5, 6, 7, 8, and 9, the brush is shown as arranged and operating at
right angles to the belts B, C.
For instance, Figure 5 is a plan, and Figure 6 an elevation of the apparatus in
which the brush L is cylindrical and operates in the direction of the longitudinal
axes of the cans, while in Figure 8 a like result is illustrated as accomplished by
means of a belt brush. In Figs. 5 and 6 the shaft 4 is used as the power shaft the
belt B, transmitting motion to the shaft 1, from which motion is conveyed by the
transmitting belt D, to the shaft 5 and thereby to the belt C. On the end of
the shaft 4 opposite to that on which the power pulley 8, is mounted is secured a
larger pulley 11, which transmits power through the belt 10 to the pulley 9, affixed
to the end of the shaft 3. On the opposite end of the shaft 3 is affixed the pulley 25
which transmits power and speed to the belt m, passing around horizontal pulleys 26,
upon the vertical standard N, to the brush pulley l, secured to the brush shaft 27.
This brush shaft 27 extends longitudinally between the shafts 3 and 4 and carries
the cylindrical brush L. The shaft 27 is supported upon the brackets O, its bearings o
being made adjustable thereon horizontally by any suitable means, as by set screws
passing through slots formed in the bases of the bearings as shown in the drawings
or by equivalent means. Provision is also made for adjusting the shaft 27 vertically

page_text: as by making the brackets O adjustable upon the standards S, as will be understood
by reference to Figure 9, or by other suitable means. The pulleys 26, are loose upon
the standard N, to allow the belt m, to adapt itself to the adjustment of the shaft 27.
It will be observed that the pulleys 26, 26, and the pulleys 25, and have peripheral
grooves in which the belt in runs; and that the pulleys 26, which are loose the
standard N, will adapt themselves to the belt m, and will be sustained by the belt in
their proper position upon the standard N. It will thus be seen that I provide for
the accurate adjustment of the brush with relation to the ends of the cans to be
treated as they pass on the ways underneath, and I am also enabled to compensate
wear. A cleaner P also adjustable is mounted between the standards S, S, and
tends constantly to dislodge particles adhering to the brush.

upon
While the use of an endless brush belt is effected in practice still owing to its
inevitable sagging it does not always bear evenly and uniformly upon the cans through
out the length, so that all parts of the soldered joint between the can body and end
plate may not receive the same treatment; furthermore, the endless brush itself has
a tendency to throw solder upon the cans, whereas by the use of a brush arranged
and operating at right angles as above set forth all cans are subjected to the same
degree of pressure and the superfluous solder is brushed off at right angles to and
away from the cans. Another advantage of rectangular arrangement of the brush.is
that the solder is positively forced under the flanges of the end plates and the
spatterings caused by centrifugal force are dislodged.
This treatment of the edges of the cans as they flow continuously through the
apparatus, to the action of a brush rotating at right angles to their line of progress
and rotation may be combined with and follow the treatment of the can to centrifugal
force for the purpose of throwing off most of the superfluous solder, especially from
the end plates and of presenting the remainder to the brush in the most favourable
position for removal thereby, although I do not limit myself to this combination,
since I believe myself to be the first to treat a plurality of cans rotated and forwarded
by an endless belt or belts to the action of a brush acting at right angles to their
line of motion.
Improvements in the Manufacture of Sheet Metal Cans.
I, ROBERT EDWARD PHILLIPS, Assoc. M. Inst. C.E., M.I. Mech. E., of 70 Chancery
Lane, in the Parish of St. Andrew's, Holborn, in the County of Middlesex; Consulting
Engineer & Patent Agent, do hereby declare the nature of this invention which has
been communicated to me from abroad by Olin Stephen Fellows, of Middletown;
Orange County, in the State of New York, U.S.A., Manufacturer, and in what
imanner 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 sheet metal cans in which the end
plates are soldered to the cylindrical bodies by passing the edges of the can over and
in contact with inolten solder. According to this method the edges of the cans take
up and carry away an excess of solder which is objectionable, not only on account of
the waste of solder, but also because the unnecessary solder detracts from the
symmetrical appearance of the can. I provide for the removal of the superfluous
solder by the use of a brush used in connection with mechanism for rotating the

page_text: cans continuously and simultaneously after they leave the soldering bath-the brush
being used either alone or in connection with mechanism for throwing off the main
excess of solder by centrifugal force as a preliminary to the finishing operation
performed by the brush. The brush in either case tends to force the melted solder
into the annular joint as well as to remove all external solder, imparting to the edge
of the can a finished or polished effect not attainable by the use of centrifugal force
alone. The action of the brush in forcibly sweeping some of the solder into the joint
while wiping off all excess is of special importance at the junction of the annular
joint with the longitudinal body joint or seam at which point there is greater
tendency to leakage owing to the overlapping of the edges of the can body.
I am aware that it has been proposed to use circular buffers or brushes to remove
superfluous solder from cans held and treated individually; I am also aware that it
has been proposed to treat cans held and rotated individually to the action of an
endless wiper belt; but neither of these ideas anticipates my invention, the
distinguishing features of which consists in treating the cans as they leave
the soldering bath to mechanism by which they will be rotated continuously
and simultaneously for the removal of superfluous solder substantially as hereinafter
claimed, thus insuring the removal of the excess of melted solder and the finishing or
polishing of the edges of the can without interfering with or retarding the continuous
flow or delivery of the cans from the soldering bath. This feature of treating the
cans for the removal of solder successively and collectively in a continuous procession
without intermission is important in the manufacture of cans in large quantities, and
I am the first to devise and invent mechanism for the removal of superfluous solder
from the cans under such conditions as contre-distinguished to the treatment of cans
specially and individually as heretofore. Thus, the saving in complication of cost of
mechanism, as well as in time, renders my method of continuous treatment of
practical utility and value under the requirements at present prevailing in the
manufacture of sheet metal cans in large quantities for industrial purposes, a
result not heretofore attained in the attempts to remove superfluous solder from the
cans.

Referring to the drawings accompanying my provisional specification :-
Figures and 2 are respectively a plan and elevation of apparatus suitable for
carrying my invention into effect, while Figure 3 is a transverse section upon plane
of line 3, 3, Figure 1.
Throughout the views similar parts are marked with like letters of reference.
Standards S, support the several shafts 1, 2, 3, 4, 5 and 6 and 7. The
power pulley 8 is secured to the shaft 1 upon which is also mounted the transmitting
pulley 9, by which power is transmitted by means of the belt 10 to the
pulley 11 on shaft 7, said pulley 11 being of greater diameter than the pulley 9.
Pulleys 12, 13, 14 and 15 support an endless belt B while the pulleys 16, 17 and 18
support a similar belt C,-the opposed surfaces of which belts receive and act upon
the cans from the rails r, r, extending from the soldering machine.
It will be seen that the adjoining and opposed surfaces of the belts B, C, travel in
opposite directions, as indicated by the arrows, and at different speeds, the upper
one B, faster than the lower, so that cans fed in between the belts by the
rails r, r, will be rotated upon their longitudinal axes and finally discharged on to
the rails 8, 8, at the opposite end of the device.
9, 9, are guard rails which preserve the alignment of the cans throughout their
journey. 19 is a spring which tends to press the cans up against the underside of
the belt B and thereby insure their entrance between both belts. The upper
shafts 1, 2, 3, 4, are adjustable vertically for the purpose of regulating accurately the
relative positions of the belts to conform to the requirements of the cans under
treatment. The pulleys 13, 14 and 17 are idlers.
Upon the shafts 2, 4, are mounted smaller pulleys 20, 21, supporting the endless
brush belt L. The pulley 22, is an idler. Pulleys 23, 24 on the shafts 2 and 4 are
connected by a cross belt D, by which power is transmitted from the shaft 4, to the
shaft 2, causing it and the pulley 23, to rotate in the opposite direction to that of

page_text: the shaft 4, and thereby imparting motion to the brush belt L, in a direction opposite
to that of the belt B.
It will be seen by reference to Figure 3 that the belts B, C, bear upon the cylin-
drical bodies of the cans while the brush belt L, is so situated that it bears against the
ends or edges of the cans which bave passed through the soldering bath.
The rails 8, 8, extend under the brush L, parallel to the upper side of the belt C,
but slightly below the upper surface of the latter the object being to sustain the cans
against depression under the action of the brush belt.
In operation the cans from the soldering machine are grasped by and between the
belts B, C, by which they are rotated upon their longitudinal axes and gradually pass
to the discharging rails 8, 8, in the meantime having their soldered edges subjected
to the action of the brush belt L, which removes all superfluous solder at the same
time positively forcing solder into or against the edges of the joints and cleaning and
polishing the edges of the cans. The solder thrown off by the brush is collected and
remelted for use.
The brush instead of being an endless belt may consist of a stationary brush of
suitable length against which the cans may be rotated as described, but the travelling
endless brush is preferable as it affords a greater amount of contact within a given
space.
In some cases, as where the exterior flanges of the end plate of the cans are wide,
owing to the depth to which the edges of the cans are necessarily submerged therein
in order to bring the edges of the end plate flanges below the surface of the solder
bath, the end plates take up and carry away an amount of solder that is entirely
useless, and which is not reached nor removed by the brush belt, that so effectually
cleans and polishes the flanges and lower parts of the can body; while on the other
hand the use of centrifugal force, as set forth in my concurrent application No. 17649
of 1897 filed herewith, while it impels the solder taken up by the end plates to the
edges thereof, and throws off most of it, it is still apt to leave residual ridges on the
edges of the can, and does not remove the solder from the cap flanges and can body
as perfectly as does the brush, for the reason that the surfaces of the flange and of
the can body are at right angles to the plane in which centrifugal force acts, whereas
the end plates coincide substantially with said centrifugal force. Hence, the centri-
fugal force may be safely relied upon to drive off the greater portion of the excess of
solder from the end plates and to carry the remainder to or over the edges of the cans
from whence it may be removed positively by the brush belt.
It will thus be seen that by the use of centrifugal force alone, while I obtain clean
end plates, I am not able to clean the flanges and adjoining portions of the can bodies
as effectually as is sometimes desirable, whereas, by the use of the brush alone, the
end plates retain most of the superfluous solder taken up by them. I have therefore
devised a modification of my apparatus in which the superfluous solder is removed by
the combined action of centrifugal force and of a brush, the centrifugal action throw-
ing off most of the superfluous solder, especially from the end plates and collecting
the remainder in the most advantageous position for removal by the brush as
hereinafter stated.
This modification is illustrated in Figure 4, by reference to which it will be seen
that the apparatus used is essentially the same, the only difference being that the
belt L, is much shorter and passes over a pulley, rigidly attached to the shaft 2, the
cross belt. D, in this case extending from a pulley 24 on the power shaft 1, directly to
a pulley 23, on the intermediate shaft. 2, so that the brush belt L, though shorter
moves in the same direction and under the same conditions as herein before described.
In operation the cams from the soldering machine are grasped by and between the
belts B, C, by which they are rotated upon their longitudinal axes with sufficient
velocity to throw off by centrifugal force the main portion of the superfluous solder
adhering to the exterior edges of the can, while at the same time they are gradually
passed towards the endless brush belt L. The distance and speed are so timed as to
effect the displacement of the superfluous solder from the end plates, or for its

page_text: collection upon the edges of the flanges, before the endless brush belt is encountered,
so that the latter, travelling as it does in a direction opposite to that in which the
cans rotate, will sweep off all remaining superfluous solder and impart a finished
appearance to the edges of the cans.
It is to be understood that in using the word "brush" herein I do not confine
myself to any special structure thereof, since any equivalent of an elastic or resilient
bristle, wires, scrapers, may be substituted for the removal of superfluous solder with
like result; neither do I confine myself to any exact form and arrangement of brush
with relation to the other parts of the apparatus.
Thus in Figures 5, 6, 7, 8 and 9, the brush is shown as arranged and operating at
right angles to the belts B, C.
For instance, Figure 5 is a plan, and Figure 6 an elevation of the apparatus in
which the brush L is cylindrical and operates in the direction of the longitudinal
axes of the cans, while in Figure 8 a like result is illustrated as accomplished by
means of a belt brush. In Figures 5 and 6 the shaft 4 is used as the power shaft the
belt B, transmitting motion to the shaft 1, from which motion is conveyed by
the transmitting belt D, to the shaft 5 and thereby to the belt C. On the end of the
shaft 4 opposite to that on which the power pulley 8, is mounted is secured a larger
pulley 11 which transmits power through the belt 10 to the pulley 9, affixed to the
end of the shaft 3. On the opposite end of the shaft 3 is affixed the pulley 25 which
transmits power and speed to the belt m, passing around horizontal pulleys 26, upon
the vertical standard N, to the brush pulley 1, secured to the brush shaft 27. This
brush shaft 27 extends longitudinally between the shafts 3 and 4 and carries the
cylindrical brush L. The shaft 27 is supported upon the brackets O, its bearings o
being made adjustable thereon horizontally by any suitable means, as by set screws
passing through slots formed in the bases of the bearings as shown in the drawings or
by equivalent means. Provision is also made for adjusting the shaft 27 vertically as
by making the brackets O adjustable upon the standard S, as will be understood by
reference to Figure 9, or by any other suitable means. The pulleys 26, are loose
upon the standard N, to allow the belt m, to adapt itself to the adjustment of the
shaft 27. It will be observed that the pulleys 26, 26 and the pulleys 25, and 1 have
peripheral grooves in which the belt m runs; and that the pulleys 26, which are
loose upon the standard N, will adapt themselves to the belt m, and will be sustained
by the belt in their proper position upon the standard N. It will thus be seen that I
provide for the accurate adjustment of the brush with relation to the ends of the
cans to be treated as they pass on the ways underneath, and I am also enabled to
compensate for wear. A cleaner P also adjustable is mounted between the
standards S, S, and tends constantly to dislodge particles adhering to the brush.
While the use of an endless brush belt is effected in practice still owing to its
inevitable sagging it does not always bear evenly and uniformly upon the cans
throughout the length, so that all parts of the soldered joint between the can body
and end plate may not receive the same treatment: furthermore, the endless
brush itself has a tendency to throw solder upon the cans, whereas by the use of a
brush arranged and operating at right angles as above set forth all cans are subjected
to the same degree of pressure and the superfluous solder is brushed off at right angles
to and away from the cans. Another advantage of rectangular arrangement of the
brush is that the solder is positively forced under the flanges of the end plates and
the spatterings caused by centrifugal force are dislodged.
This treatment of the edges of the cans as they flow continuously through the
apparatus, to the action of a brush rotating at right angles to their line of progress and
rotation may be combined with and follow the treatment of the can to centrifugal
force for the purpose of throwing off most of the superfluous solder, especially from
the end plates and of presenting the remainder to the brush in the most favourable
position for removal thereby, although I do not limit myself to this combination,
since I believe myself to be the first to treat a plurality of cans rotated and forwarded
by an endless belt or belts to the action of a brush acting at right angles to their
line of motion,
