Improvements in and relating to Machines for the Manufacture of
Metal Cans and similar Articles.
I, DAVID YOUNG, Patent Agent, of the Firm of D. Young Co., of 11 and 12,
Southampton Buildings, London, W.C., do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
My invention has for its object the production of a series of mechanisms for
treating the blanks from which tin can bodies are formed, prior to their insertion
into the body-forming machine; and my invention embraces, broadly speaking.
1st. Mechanism for successively feeding the blanks from a pile or stack thereof.
2nd. Mechanism for shaping and cutting a strip of solder of the proper length
and placing it in the proper position upon the blank.
3rd. Mechanism for hemming or engaging the strip of solder onto the blank at
the desired point and
4th. Mechanism for fluxing the strip of solder after it is placed on the blank.
The invention also contemplates other minor mechanisms for use in combination
with the above specified mechanisms, such as a new form of clutch mechanism,
which will be hereinafter explained more in detail.
These mechanisms may of course be embodied in one organized machine such as
shown in the drawings of this application, or they may be separated and each set of
mechanism be employed in connection with other styles of mechanisms. In the

In carrying out the invention A represents the main bed plate or frame of the
machine supported from suitable standards' A¹ it being of course understood that
the size and the shape of the main supporting frame is immaterial.
I will first describe the main driving mechanism for the entire machine.
1 (Figure 4) represents the main shaft journaled in the standard A. On the
sleeve 2 which has a rotary motion around the shaft 1 is the belt pulley 3 driven
by a belt. This belt pulley has its hub flanged as at. 4 (Figure 20). Carried
by the shaft 1 and keyed thereto by the feather 5 is the hub 6 having the outwardly
extending flange 7. Through the outer rim of this flange 7 are orifices 8 through
which are
passed bolts 9. Supported by these bolts is a ring 10 adapted to embrace
one side of the flange 4 while the flange 7 embraces the other side and thus when
the flanges 7 and 10 are brought together they clamp the flange 4 between them.
Springs 11 tend normally to keep the flanges 7. and 10 apart so that the flange 4
can freely revolve between them. On the hub 6 is a sleeve 12 engaged by a ring
or yoke 13. The latter being engaged by a lever 14 and the end of the lever pivoted
to an arm 15 on the standard A¹ (Figure 4). Thus a movement of the lever 14
will throw the sleeve 12 along the surface of the hub G. Connected with the
collar 12 by links 16 are levers 17 (Figures 19 and 20) one end of each lever 17
being pivoted to the link 16 while the other end is provided with an orifice which
embraces the bolt 9.
The head of each lever 17 is beveled on each side as at 18, one side of the head
entering the orifice 8 in the flange 7 while the other side enters a button 19 on
the bolt 9, lock nuts 20 being employed to regulate the parts. It will thus be seen
that when the parts are in the position shown by full lines Figures 20, the springs 11
tend to keep the flanges 7 and 10 apart but when through movement of the sleeve 12
the levers 17 are thrown to the position shown by dotted lines Figure 20, the
leverage exerted by the levers 17 draws the flanges 7 and 10 together and they
clamp the flange 4 and hold it tightly. By the nuts 20 the driving capacity of the
clutch is easily regulated. The band pulley 3 is of course constantly revolving and
when the flange 4 is clamped, it immediatley gives rotation to the shaft 1. Located
on the shaft 1 is a pinion 21 (Figure 4) which meshes with the pinion 22 on the
stud 23, the latter being supported from the standard A. On this stud and engaged
to the pinion 22 is a sprocket wheel 24. Supported from suitable standards A³
(Figure 4) is a shaft 25. On this shaft is a hub 26 capable of rotation on the
shaft 25 and carrying a sprocket chain 28 with the sprocket wheel 24. On the face
of the sprocket wheel 27 is a projecting wheel or bearing 29 carrying a pin 30
(Figure 2). The end of this pin is pivoted to a lever 31, the lever being pivoted
to a projection 32 on the face of the sprocket wheel and a spring 33 tending to keep
the lever 31 and pin 30 normally in the position in Figure 2. Keyed to the shaft 25
is an arm 34 having on its ends the sleeve 35 which, as shown in Figure 4, is set
at an oblique angle to its path of rotation. In this sleeve 35 is a pin 36 provided
with a spring 37 to keep it normally in the position shown in Figure 2. When the
pins 30 and 36 are in the position shown in Figure 2 the pin 30 will in its rotation.
engage the pin 36 and thus revolve the arm 34 and consequently the shaft 25.
The end of the pin 36 is beveled as shown in Figure 4 so that in case an unusual
strain comes on the mechanism such as a clogging of the parts or the like, the
spring 37 will yield and thus allow the pin 30 to pass the pin 36 so that the main
shaft can continue to revolve while the mechanism stops. Again, it is often desired
to stop the mechanism for one revolution of the shaft or for a predetermined number
of revolutions thereof. This I accomplish as follows:-On the shaft 25 is a
collar 38 adjacent to which the tail 39 of the lever 31 terminates. The collar 38
has a sliding motion on the. shaft 25 and when moved in the direction of arrow X

page_text: (Figure 2) it strikes the tail 39 of the lever 31 and tilts the latter, thus withdrawing
the pin 30 as shown in Figure 4. Any suitable mechanism may be employed to
move, the collar 38. I have provided a rod 40 journaled in the bed plate and pro-
vided with an arm 41 which, when the rod is rotated, will press against the collar 38
and move it. The rod 40 is provided with a hand lever 42 and if desired may be
provided with an additional arm 43 and a rod 44 pivoted thereto and extending to
adjacent mechanism. I will at this point explain that my present machine has
heretofore been used in connection with a rotary can body forming machine which
takes the blanks as they are prepared by my present mechanism, forms them into
a body and solders them into that shape. It frequently happens that only a portion
of the capacity of the can body machine is used or it happens that one or more sets
of soldering mechanism is out of order. To provide for delivering to the can body
machine only the number of blanks required, I provide on any suitable rotary part
of the can body machine, such for instance as indicated at X (Figure 1) and at
proper intervals pins X. Pivoted to the frame of the can body machine is a
lever X3, one end X³ terminating in the path of the pins X' while the rod 44 is
pivoted to the body of the lever. Thus a tilting of the lever X2 by the pin X' on
the can body machine, exerts a push on the rod 44 which in turn rotates the rod 40
and through the collar 38 tilts the lever 3.1 and withdraws the pin 30 so that for
that revolution the motion of the mechanism ceases.
I will now describe what I term the blank feeding mechanism:-Extending
from the bed plate (Figures 1 and 2) are suitable standards A2 and on the upper
ends of these standards and preferably integral therewith is a plate B (Figure 3).
Extending upwardly from this bed plate B are strips B (Figure 3) connected by
cross strips 12 and forming a rack or hopper and supported by the projections bon
the bed plate B are standards or yokes C, there being two for each side of the
hopper. Each of these standards forms a bearing for a shaft D. In Figure 15 I
have shown one of these shafts in detail with adjacent parts in section. It will be
observed that the shaft D is supported vertically at the lower end by the set screw d
in the bearing on the bed plate, the head 12 being employed to raise and lower
the screw while the lock nut d sets it. It is held from vertical movement at its
upper end by the plug ². The standard C has its upper end split and held by the
screw e to clamp the plug ². Engaged on the shaft D is the beveled pinion 1".
Above the beveled pinion is the projection 620 extending from the bed and above
this the lower end of the yoke C. Above the yoke is what I will term the knives D*
-DD and D7 (Figure 1). One of these knives is shown in Figures 16 and 17.
It consists of a hub proper D8 with a peripheral flange having a more or less
sharpened edge d. This edge is preferably brought to more or less of a point
as at and the edge is preferably substantially radial with the shaft. It will be
observed by reference to Figure 1 that the shafts D are so arranged with respect to
the hopper, that as the knives revolve, the edges thereof enter the hopper. Journaled
in the standards A² (Figures 2 and 3) are shafts E-E' each carrying a pinion E2
which meshes with a pinion E on the shaft E. The latter being journaled in a
sleeve E supported by a suitable depending arm extending down from the bed
plate Bas indicated by dotted lines in Figure 6. On each end of each shaft E-E
is a beveled gear E, the beveled gears E meshing with the beveled gears D¹ on
the shafts D: Thus a rotation of the shaft E revolves each of the shafts D and
consequently the knives D' to D'. The shaft E is driven by a sprocket wheel E
(Figures 12 and 6), a sprocket chain E, a sprocket wheel E (on the shaft F,
Figure 1), the shaft F being driven by a pinion F meshing with a pinion F on the
stud (the latter supported from the bed), the pinion F2 meshing with the
pinion F on the shaft 25 (Figure 6). If desired, an idler sprocket wheel E¹º sup-
ported by the arm E" which extends from the bed plate, may be employed to keep
the sprocket chain always taut. In the bed plate B (Figure 1) at each corner are
small blocks bbb and b³, there being one for each knife D' to D' and each block
located substantially below the point where the knife enters the hopper above the
bed plate. I have found the best results have been obtained where the

page_text: knives D6 D7 are about 1/16 of an inch, and the knives D-D about 1/32 of an
inch above the surface of the bed plate B while the surfaces of the blocks — b² — bis
are about 1/100 of an inch and the surface of the block b about 1/50 of an inch above
the surface of the said bed plate. With this arrangement as the knives revolve the
knives D6 D7 will enter the stack of plates and parting them will lift the bulk of
the plates while from 3 to 6 plates (depending upon the thickness of the plate) will
rest upon the blocks 62-63. The knife D will as it enters the stack of plates,
part them and lift them all but perhaps 1 or 2 or sometimes 3, while the knife Di
entering the stack of plates will part them leaving but a single plate below the knife
and lifting the balance. By thus parting the stack at a higher elevation on one
side, and leaving but a single plate below the knife at one point, the necessity of
accurate adjustment is largely obviated and mechanical accuracy insured. While
the single plate is below the knife D and the balance of the plates lifted away from
it, a reciprocating block engages the corner of this lower plate and pushes it out
of the hopper. This pushing mechanism I will now describe. In the bed plate B
is a slot 6 (Figures 1 and 2). Working therein is a block 65 carrying a smaller
block 66 the latter liaving a projection adapted to engage the corner of the lower-
most plate in the hopper. The block 65 (Figure 3) is connected by the link b
with one arm 69 of a bell crank lever on the stud 6, the latter supported by the
arm depending from the bed plate A. On the end of the other arm bu is a
roller 62 On the shaft 25 (Figures 2 and 3) is a cam plate 63 having a cam
groove 14 in which the roller 6 travels. The cam groove 64 being so shaped
that at regular intervals it will give a quick oscillation to the arm and conse-
quently a quick reciprocation to the block 65. Briefly, the operation of this feeding
mechanism may be described as follows:-The knives D to D being revolved by
the mechanism heretofore described, act to lift the main portion of the stack of
plates in the hopper, leaving below the knives at one side of the hopper perhaps
two or three or four plates while below the knife at one corner there is but a single
plate. After the lifting of the plates is accomplished, the pushing block bis thrown
forward and forces the lowermost plate out of the hopper, the block being thrown
back to its initial position before the knives have completed their revolution and
allow the stack of plate to drop again.
I will now describe the mechanism for forming the strip of solder so that it may
be properly engaged to the blank which later forms the can body. G (Figure 5)
is a lever pivoted to the frame A, one end connected by a spring to the frame A
to exert a tension to keep the lever normally in the position shown in Figure 5.
On the upper end of the lever is a roller G2 which carries a strip of solder G³ or if
desired the solder can be carried from any other source of supply. H. (Figures 2
and 5) is a frame pivoted to the bed plate A by the pivot a (Figure 1) in which the
solder forming and moving mechanism is carried. H' is a vertical shaft carried by
the frame H, said shaft having on its upper end a pinion H³. This pinion meshes
with a pinion H+ carried by a, roller H on a stud H2 so that a revolution of the
shaft H revolves the pinion H+ and roller H. On the shaft H¹ below the pinion H³
is a roller H. The roller He has its periphery made V shaped in cross-section
while the roller H has its periphery of an inverted V shape as at h. G (Figure 2)
is a roller supported by the arm G5 from the frame H, and adapted to act as a guide
roller for the strip of solder. As will be seen when the strip of soft solder is fed
between the rollers HH, it will not only be drawn along by the revolutions of
the rolls but it will take the V shape of the periphery of the rolls. The revolution
of the shaft H is accomplished as follows:-On the shaft is a ratchet wheel G
(Figures 2-5 and 18). A pawl G7 (see Figure 18) pivoted to the upright G8
(Figure 2) and kept in contact with the periphery of the ratchet wheel by the
spring G, see Figure 2, prevents the ratchet wheel from revolving except in one
direction. Pivoted on the shaft H is an arm GC carrying a spring impelled
pawl G (Figure 18) (the spring not being shown), adapted to engage the teeth of
the ratchet wheel G. This arm Go is oscillated by means of the pitman G12
engaged at one end by the projection G¹³ (Figure 5) to the arm G10 and at the other

page_text: end to the adjustable arm G on the end of the arm G¹³. The latter is on the
shaft G and on the same shaft is an arm G7 having a roller on its end G18 which
enters cam groove G19 of the cam G20 on the shaft 25. It will be observed by refer-
ence to Figure 5 that the engagement between the pitman G12 and the arm G¹
and between the pitman G2 and the arm G3 is in each case a ball joint. It will
also be observed that the arm G is adjustable on the arm G15 by means of the set
screw and slot g' so that the combined arm G-G15 can be lengthened or
shortened and thus vary the length of the path of oscillation of the arm G¹º and
consequently vary the amount of solder fed. In order that the feed of solder may
be automatically stopped at intervals (the necessity of which I will later explain) I
provide adjacent to the path of the movement of the pawl G" a curved arm H
adapted to engage the tail of the pawl and hold the pawl from engagement with
the ratchet wheel G. This curved arm H is supported from the arm H8 (Figures 5
and 18), the latter being on the shaft H9 supported by the sleeve H10 on the frame H.
On the shaft H9 is another arm H (Figure 4) pivoted to the end of which is a
pitman H and at the other end of which is pivoted the arm H³ (Figure 1). The
arm H3 is pivoted on a shaft H+ supported from a sleeve H carried by the standards
of the hemming rolls (which I will presently describe). On the shaft H¹ (Figures 4
and 5) is an arm H This arm H is directly in the path of a blank as it leaves
the hemming rolls which acts to tilt the arm to the position shown by dotted lines
Figure 5. This tilting of the arm H¹ acts through the parts just described to tilt
the curved arm H7 upward and clear of the pawl G", so that the latter can act on
the ratchet wheel G and thus feed the solder. Thus as a blank is leaving the
hemming rolls and the mechanism which I will presently describe for hemming
the solder onto the blank, is empty, a new feed of solder is obtained, but while there
is a blank in the hemming rolls the arm H16 is down or in the position shown in full
lines Figure 5 and a feed of solder is prevented. J is what I will term a receiving
tube for the solder and is shown in detail in Figures 7 to 12 and also in Figure 3.
It is made of two parts - (Figure 11) the face of the parts j being of a V shape
in cross section while the adjoining face of the part j is an inverted V shape; the
result being a V shaped slot extending the length of the tube. The part j', has
also a flaring front or mouth 3, while the part has a horizontal slot extending
backward from the V slot. This tube J is located with the end closely adjacent
to the shaped rolls H H so that as the strip of solder is formed by the
V shaped rolls and discharged, it enters the receiving tube J and is forced along
in said tube. In the tube J is a slot j extending vertically through the tube but
placed in an inclined position with respect to the length of the tube. At the rear
end of this slot is a steel piece 7 forming an abutment against which the cutting
knife bears and between which and the cutting knife, the solder strip is cut as will
be hereinafter described. The cutting knife works in this slot and cuts the
requisite lengths of solder off from the strip that is forced into the tube. This
cutter knife I will now describe: Supported from the bed A of the machine is a
bearing K carrying a shaft K'. On this shaft is an arm K² carrying on its end
the cutter knife K, the shank or tang of which is bent and engaged to the arm K²
by the screws k, as shown in Figure 13. The end of the knife K³ is V shaped as at k¹
and sharpened. Upon the shaft K¹ is another arm K having the portion which
embraces the shaft split and held by a set screw ³. Surrounding the shaft K' is
a spring bearing on the arm K and as the shaft has an endwise movement the
spring tends to normally keep the knife against its bearing in the slot. A
spring tends to normally keep the knife in the position shown in Figure 13.
Pivoted to the arm K' is a downwardly projecting rod K³ extending through the bed
plate and terminating adjacent to and above the pivoted arm K. This pivoted
arm Ko terminates closely adjacent to the cam plate G20 and on the face of the latter
is an arm K8 having a projection K9 arranged in an inclined position as shown so
that the revolution of the disc G20 will bring the projection K against the beveled
end of the arm K6 and will tilt the latter upward thus thrusting the arm K³
upward which in turn tilts the arm K and thus causes the knife to enter the slot ja

page_text: and cut the strip of solder that is in the tube J. By reference to Figure 14 it
will be seen that the knife is beveled from its cutting edge backward. This fact
together with the inclined position of the slot causes the strip of solder after it
has been cut to be forced along slightly in the tube J by the continued advance-
ment so that as the strip is picked up by the blank as hereinafter described, the
vertical plane of the end of the solder strip will be beyond the vertical plane of the
edge of the blank, and as the solder strip is picked up and carried along by the blank,
there will be no projecting end of the solder to catch and disarrange the parts.
I will now describe the mechanism for hemming the strip of solder onto the
edge of the blank. Extending from the bed plate A are standards M-M. Carried
by these standards are boxings M2 (Figure 5) and journaled in these boxings are
the rolls MM4 (Figure 3). The boxings of the roll M³ are adjustable vertically
by means of the screws M5 so that the distance between the two rolls can be easily
varied and the upper roll is normally held down by the springs M8 (Figure 5) so
that the roll can accommodate itself to varying thicknesses of blanks. The roll M* is
mounted on the shaft F which as above explained is driven by the pinion FF2-14
from the shaft 25. The pinion F¹ on the shaft F meshes with the pinion M on the
shaft M6 of the roll M³ so that the two rolls will revolve in unison and in opposite
directions. By reference to Figure 3 it will now be understood how the various
parts above described co-operate with each other. By the intermittent feed of the
solder a strip of the latter is forced into the tube J after being formed V-shaped
and there cut off as described. The lowermost blank in the hopper is forced forward
as described, the end entering the mouth 3 of the tube J and, picking up the strip
of solder, forces it out through the slot to the rolls MM, the latter hemming
the solder onto the end of the blank (shown in Figure 11). Extending from the
bed plate A are standards N (Figures 3 and 6) which support the operative parts
which I will now describe. Supported from the standard N is what I will term a
guideway made up of the two plates N¹-N2 (Figure 3). The ends of these plates
are flared as at n and terminate closely adjacent to the rolls MM so that as
the blank with the strip of solder hemmed thereon is discharged from the rolls, it
enters this guideway and before the rear end of the blank has left. the rolls M3-M*,
the forward end has reached a point underneath the yielding plate N3 (made yield-
ing by virtue of the springs N₁), lifted the latter and held thereby until picked up
by the lugs p on the endless feed chain P-P. As will be seen by reference to
Figure 1, this feed chain is composed of two parts, each travelling on a sprocket
'wheel P on a shaft 13, the shaft being supported by the sleeve P and the latter
supported from the bed plate A. The opposite ends of the feed chains pass over
sprocket wheels at the point where it is desired to deliver the blanks. These wheels
are not shown but the construction at this point would depend entirely upon the
machine to which the blanks are delivered and in case no other mechanism is desired
at this point, the sprocket wheels for supporting the chains could be constructed
by any person skilled in the art in any of the usual well known ways. The
shaft is driven by a sprocket wheel P, a sprocket chain P, a sprocket wheel P7
on the shaft P8 and the latter driven by a beveled gear P meshing with a beveled
gear Po on the shaft F. On the shaft 18 is a pulley Q (Figure 1) carrying a
belt Q passing over a pulley Q² supported on a counter-shaft Q3, the latter sup-
ported by the arm Q extending from the bed plate (Figure 5). Pivoted to the
arm Q is a bearing Q5 carrying a shaft Q. On the end of each shaft Q-Q is a
disc of felt or equivalent material Q7, the peripheries of the two discs Q being in
contact with each other. Below the lower disc Q7 is a vat Qs for containing any
suitable flux. Now as will be seen, when the blank is discharged from the hem-
ming rolls and is picked up by the endless chain carrier P-P it is carried along
in the direction in which the chain is moving but its forward end on which the strip
of solder has been hemmed is not over far enough to pass between the fluxing
discs Q. In order to carry it over to this point I have provided the lever R
(Figures 3-5 and 6) the lower end r of which terminates adjacent to a cam R¹ on
the shaft 25, while the upper end is curved at r² so that it terminates closely

page_text: adjacent to the hemming rolls. Pivoted to the lower end of the lever is a rod R³
having a set nut R³ the end of the rod passing through an orifice in the arm Ron
the bed plate A (Figure 3) and the spring R being provided between the arm R
and the set nut R³. The position of the cam R on the shaft 25 is such that at
the proper time the cam will bear upon the end r of the lever R and tilt the upper
end back to a position adjacent to the rear end of the blank as it leaves the hemming
rolls. Then as the blank is picked up by the endless chain P-P and moved along,
the rear end of the blank is brought in front of this arm R. At this time the
cam R¹ runs off from the end of the lever R and the spring R which has been
compressed returns the lever R to its normal position and the lever thus engages the
rear end of the blank and forces it over so that the forward or solder end of the
blank will be in line with the fluxing discs. The endless chain P-PI continues to
slide the blank along until it has passed between the fluxing discs and as the latter
have picked up flux from the vat, the flux is distributed along the solder. The
endless chain then carries the blank to the desired point for the next operation.
Inasmuch as I have described the operation of each set of mechanism inde-
pendently, I do not consider it necessary to again describe the complete operation
of the machine.
