IMPROVEMENTS IN MACHINERY FOR SECURING THE ENDS OF SHEET METAL CANS,
CASES, OR BOXES."
My Invention relates to improvements in machines for crimping or securing the
bottoms of sheet metal cans or other vessels upon their bodies or sides, and is more
especially designed for use with cans, boxes, or similar receptacles having the form
or shape of a parallelogram.
In machines as heretofore constructed for this purpose a crimping head is
employed in combination with a former head, adapted to receive the body or sides
of the can upon which the bottom is to be secured. This crimping head is of such
a shape that its periphery adapts itself to the form of the can body placed upon
the former head and crimps the bottom upon the same. In operating with the
machine a can body is placed upon the former head, which is of the same shape as
the said body, and the bottom for the can is then placed upon the said body. The
crimping head is then brought down by a treadle into contact with the flange on
the can bottom, and the crimping head and former head being then revolved the
periphery of the said crimping head crimps or secures the bottom upon the sides.
The bottoms employed are flat and are provided with a flange all around to fit over
the sides of the can, and the crimping head is provided with a flange to retain the
bottom in position upon the body during the crimping operation.

page_text: It has been found in practice however that a flat bottom having a rim or flange,
which is crimped or secured over or upon the exterior only of the body or sides of
the can is disadvantageous for the reason that the sides are liable by concussion or
from other causes to bend or receive a "set" inwardly, thereby becoming discon-
nected from the flange on the bottom and permitting the contents of the can to
escape.
To obviate these defects I so construct a machine that it is adapted to crimp or
secure upon the body of the can a bottom, which instead of being flat and provided
with a turned up flange is provided with a somewhat U-shaped flange extending
below the flat portion of the said bottom, and thereby constituting a rim within
which the body of the can is crimped.
For this purpose instead of employing a former head of the same shape as the
body of the can, and adapted to receive the same, I fix upon a shaft supported in
suitable bearings in the frame of the machine a head, which is provided with a
projecting portion upon which the bottom is placed, the flange of the said bottom
surrounding the periphery of this projecting portion. In combination with this
head I employ another head, which may be moved longitudinally towards the
revolving head by means of a suitable band lever, and which is designed to receive
the body of the can upon which the bottom is to be crimped. Above the shaft
carrying the revolving head I arrange the shaft which carries the crimping head.
This crimping head consists of a flat plate whose peripheries is provided with con-
cavities or recesses, which as the said plate revolves pass around the corners or
angles of the bottom and preserve an even pressure upon the same. The crimping-
head shaft is supported in suitable bearings, and is so arranged that it may be
moved or swung vertically so as to be released from or brought in contact with
the work by a suitable connection to a treadle. By this means when the bottom
of the can is placed on the revolving head, and the edge of the body of the can is
forced into the U-shaped flange of the said bottom by moving the can body-
carrying head lengthwise, the operator by depressing the treadle can bring the
crimping head down to crimp the said bottom upou the body. The shaft carrying
the crimping head is provided with a gear wheel, which meshes into a gear wheel
upon the shaft carrying the revolving head upon which the bottom is placed. The
last named shaft is provided with a driving pulley which runs loosely upon the
same. In combination with this pulley I arrange suitable clutch mechanism, so that
when the treadle is depressed to bring the crimping head down upon the work the
said pulley will be clutched to a disc or wheel fast on the shaft carrying the revolving
head, and will impart motion to the saine and a corresponding motion to the
crimping head. When the treadle is released the pulley is again free to run loose
upon the shaft, and the crimping head and bottom carrying head remain stationary
to permit the removal of the can after the bottom is secured upon the same.
sliding head for carrying the can body is also geared with the shaft provided with
the bottom carrying head, and revolves at the same speed as the latter. In
operating with this machine the can bottom is placed upon the carrying head and
the can body upon the sliding head, which is then moved longitudinally to bring
the end of the can body within the U-shaped flange projecting from the can bottom.
The operator then depresses the treadle to bring the crimping head down upon
the work, and at the same time sets the various parts in motion, thereby crimping
the body firmly between the U-shaped flange on the bottom. When the crimping
is completed the treadle is released, and the machine stops to enable the can to be
removed, and the operations above described are then repeated.
The
By thus securing the can bottom on the body I avoid all liability of its sides
to be forced inwards by pressure, as the end or edge of the body is firmly clamped
or secured between the two sides of the U-shaped flange instead of being clamped
ou one side only.

JANE ELIZABETH PARRY, of No. 290, Camden Road, Islington, in the County of
Middlesex, Widow and Sole Executrix of the late Edward Parry, of New Bridge
Street, in the City of London, Iron Merchant. "IMPROVEMENTS IN MACHINERY
FOR SECURING THE ENDS OF SHEET-METAL CANS, CASES, OR BOXES."
My Invention relates to improvements in machinery for "crimping" or securing
the bottoms or ends of sheet metal cans or other vessels upon their bodies or
sides, and is more especially designed for use with cans, cases, boxes, or similar
receptacles having the form or shape of a parallelogram. Machines of this class
are in some cases termed "wheeling on" or seaming machines.
In machines as heretofore constructed for this purpose a crimping or compressing
head is employed in combination with a former head, adapted to receive the body
or sides of the can or vessel upon which the bottom is to be secured. This
crimping head is of such a shape that its periphery adapts itself to the form of
the can body placed upon the former-head, and crimps the bottom upon the said
body. In operating the said machines a can-body is placed upon the former head,
and the bottom or end piece for the can is then placed upon the said body.
The crimping head is then brought down by a treadle into contact with the flange
on the can bottom, and the crimping head and former head being revolved, the
periphery of the said crimping head crimps or compresses the bottom upon the
sides or body, and the bottom and body are thus secured together. The bottoms
employed are flat, and are provided with an upturned flange to fit and be crimped
over the sides or body of the can, and the crimping head is provided with a flange
to retain the bottom in position upon the body during the crimping operation.
It has been found in practice however that a flat bottom having a rim or flange
which is crimped or secured over or upon the exterior only of the body or sides
of the can is disadvantageous, for the reason that the sides are liable by concussion
or from other causes to bend or receive a "set" inwardly, thereby becoming
disconnected from the flange on the bottom, and permitting the contents of the
can to escape.
To obviate these defects I so construct a machine that it is adapted to " crimp"
or secure upon the body of the can or vessel a bottom or end piece, which instead
of being flat and provided with a turned up flange, is provided with a flange which
is U-shaped or approximately so in transverse section, and which extends below
the flat portion of the said bottom, and thereby constitutes a rim within whichthe
body of the can is crimped.
My Invention is illustrated in the accompanying Drawings, in which,—
Figure 1 is a plan, and
Figure 2 a side elevation of my improved machine.
Figure 3 is a transverse section of the same on the line x, x, Figure 1.
Figure 4 is a face view, and
Figure 5, an edge view drawn to an enlarged scale of the crimping head of the
said machine.
Figures 6 and 7, and Figures 8 and 9 are similar views of the heads for
receiving the bottom and one end of the can body upon which such bottom is to be
secured.

page_text: Figure 10 is a central section of a can body with the bottom in position to be
secured or crimped thereon.
Figure 11 is a similar view shewing the said bottom when crimped upon the
body of the can by the said machine.
Like letters indicate the same parts throughout the Drawings.
a represents the main frame of the machine, which is supported on suitable
standards a¹; b is the main or driving shaft carrying the head c for the reception of
the can bottom, and d is the crimping or compressing head fixed upon the shaft e;
fis the adjustable head designed to press against one end of the body of the can to
retain its other end within the rim of the can bottom during the crimping
operation; g is the shaft carrying the said head. The remaining parts are
hereinafter described.
In order to secure a can bottom having a grooved rim, as above described and
as shewn in Figure 10 upon the can body, I employ instead of the former-head
heretofore used the head c, which is of the proper shape to receive the said bottom,
whose flange or rim surrounds the edge of the said head when placed thereon, as
shewn in dotted lines in Figure 2. In combination with this head c I employ the
head which may be moved longitudinally towards the head c by means of a
hand-lever h, and which is designed to receive one end of the body of the can upon
which the bottom is to be crimped, as above stated. This head f is provided with
a projecting portion f' designed to fit within the body of the can when placed in
position, as shewn in dotted lines in Figure 2. This projecting portion prevents
any displacement of the can body during the crimping operation. Above the
shaft I arrange the shaft c which carries the crimping head d, and which
receives motion from the said shaft b through the gear-wheels 1, 2.
This
crimping head consists of a flat plate or disc whose edge or periphery is inclined
or bevelled, and is provided with a series of curved portions d' which pass over
the straight portions or sides of the bottom and body of the can, and with a
series of concave or straight portions d, which as the said head revolves pass
around the corners or angles of the said bottom and body, so as to preserve an
even pressure upon the same. The shaft e is supported in suitable bearings within
a frame or carrier i pivotted at a* to the main frame a, and is so arranged that it
may be moved or swung vertically to raise the crimping head from or bring it into
contact with the can bottom. For this purpose I prefer to employ a rod or bar
extending from the piece i¹ to a treadle arranged below the table upon which the
machine is fixed. When the bottom of the can is placed on the head or block c,
and the end of the body is held in the flange or rim of the said bottom or end
piece by the pressure due to the longitudinal adjustment of the head f, the operator,
by depressing the said treadle, can depress the crimping head or disc d to crimp or
compress the said bottom upon the body, as shown in Figure 11. To impart
rotary motion to the head f, I provide a shaft j supported in suitable bearings in
the main frame of the machine, and attach to the same a gear-wheel 3 which
meshes into the gear wheel 1 on the main shaft b. The shaft also carries a gear-
wheel 4 which engages with the gear-wheel 5 on the shaft g, the said shaft and
wheel being combined with each other by a key or feather and keyway or groove,
to permit the longitudinal adjustment of the said shaft, whilst at all times ensuring
the revolution of the same with the said gear-wheel 5. Upon the shaft b I provide
a driving pulley k which runs loosely upon the same. In combination with this
pulley I arrange clutch mechanism, which is so constructed, that when the treadle
is depressed to bring the crimping head down upon the can-bottom, the said pulley
will cause the shaft b to revolve; whilst, when the said treadle is released, the said
pulley will again run loose upon its shaft, and allow the same to remain stationary
to permit the removal of the can bottom and body, which have, by the above
described operations, been secured together. Another can bottom and body may
then be placed in position, the above described operations being repeated.

page_text: The said clutch mechanism is constructed as follows, that is to say :-Adjacent
to one side of the said pulley k, and fixed on the shaft b, I arrange a disc l which is
provided with a stud or pin l, and on the other side of the said pulley I arrange a
disc m capable of sliding endwise upon the shaft b, and provided with a pin m¹
which passes through a suitable aperture in the pulley k, and whose outer end is
flush with the face of the said pulley when the crimping head is in its elevated
position. The said disc m is also ed with a bush or hub m², provided with
the annular groove m³ for the reception of segments m* combined with the forked
end of a lever n by screw m°. This lever is pivoted at o* to the fixed supports
or brackets o attached to the main frame a, and is connected at its forward end by
a screw p to the crimping head carrier i, as shewn, so that when the said carrier is
lowered by the depression of the treadle to bring the crimping head down upon the
work, the said lever n will be caused to rock upon its pivot or fulcrum, and its
forked end will effect the end wise movement upon the shaft 6 of the disc m, and
thereby cause the pin m³ upon the latter to project beyond the face of the pulley k,
and into such a position, that in the revolution of the said pulley, the said pin m¹
will engage with the pin of the disc 1, and thereby revolve the same, and con-
sequently the shaft b combined therewith. q represents a spring which serves to
force the crimping head carrying frame i upward when the treadle is released, and
thereby withdraw the pin m¹ from engagement with the pin l, to throw the
heads c, d, f, out of gear with the said driving pulley.
To adapt the machine for securing the bottoms on sheet metal cans, cases, or
vessels of different sizes and shapes, I provide the said machine with a series of
interchangeable heads c, d, and f, each one of which is different with regard to size
and configuration from the others, such heads being suited to the particular forms
and dimensions of the bodies and bottoms of any cans or vessels that may be
required.
The operation of the said machine is as follows, that is to say :-The can bottom
with one end of the can body inserted within the groove in the same is placed upon
the head c; the sliding head is then moved longitudinally, so that its projecting
portion enters the other end of the said can body, and holds the same and the
botton firmly in their proper relative positions. The operator then depresses the
treadle to bring the crimping head d down upon the work, and at the same time
causes the aforesaid clutch mechanism to be thrown into gear, and set in motion the
various parts of the machine, thereby crimping and securing the body firmly within
the flange or rim on the bottom. When this crimping action is completed, the
operator releases the treadle, the said clutch mechanism is thrown out of gear,
and the machine stops to enable the can to be removed, the operations above
described being repeated until the required number of cans has been furnished with
heads.
By thus securing the can bottom on the body, I avoid all liability of its sides to
be forced inward by pressure, as the end or edge of the body is firmly clamped or
secured within the Hange or rim of the bottom, as shewn in Figure 11, instead of
being clamped on the exterior of the body only, as in the machines heretofore
constructed.
Having thus fully described the said Invention, and shewn how the same may be
conveniently and advantageously carried into practice, I wish it understood that I
claim,―
First. In a machine for securing the bottoms or ends of sheet metal cans, cases,
or boxes to their bodies, the crimping or compressing head or disc, the head or
block upon which the bottom is placed, and the adjustable head for retaining the
body of the can or vessel in the desired position during the action of the crimping
head or disc, all constructed, combined, and operating, substantially as above set
forth.
Second. The combination with the parts forming the subject matter of the

page_text: preceding claim, and operating as herein described, of the clutch mechanism and
gearing, substantially as above set forth and for the purposes specified.
In witness whereof, I, the said Jane Elizabeth Parry, have hereunto set my
hand and seal, this Ninth day of February, in the year of our Lord One
thousand eight hundred and eighty-one.
Signed, sealed, and delivered
by the above named Jane
Elizabeth Parry, in the
