(Cl. 113-121)
This invention relates to a receptacle closure
and to a method by which to produce said clo
Referring to the drawing for describing in
detail the invention as shown therein, the refer 25
ence character L indicates a top Wall portion of
the closure, the reference character G indicates
the outer cylindrical wall part of the annular
skirt portion of the closure and the reference
character H indicates the inner wall part of the 30
annular skirt portion of the closure.
The top wall portion and the outer wall part
of the skirt portion may be perfectly plain or may ~
be ornamented with color or embossing, or other
wise, as preferred by the manufacturer.
35
The inner wall part H extends, as an inturned
part of the outer wall, from the lower margin of
the skirt upwardly to near the under surface of
the top wall portion. It may of course extend
entirely to said under surface if desired but it 40
preferably stops short of said under surface and
thereby provides an annular recess as l within
the closure into which may extend the annular
marginal portion of a gasket or liner disc or the
like 2, as clearly indicated, the gasket or liner 45
being thereby e?iciently held against accidental
displacement from within the closure at all
times.
The gasket or liner 2 may be wedged into posi
tion after the metallic portions of the closure have
been completed or it may be placed within the
closure prior to bending in the inner wall part H.
When inserted prior to the bending in of the wall
part H said wall part may be caused to press
?rmly against the marginal portion of the'gasket

wall H from the inner surface of wall G.
In Figs. 7 to 12 is illustrated the several essen
tial steps proposed herein as the method by which
The material constituting the inner wall part H
is spirally corrugated throughout so as to form
continuous interior threads as 3 for screw en
gagement with the continuous threads of a re
ceptacle as will be readily understood.
The inner wall part H is spaced inwardly fromv
10
the inner surface of the wall part G so that the
.wall part G is thereby at all times held spaced
away from any solid engagement with the recep
tacle. In the event of a blow being struck against
15 the outer surface of the wall part G the spacing
of the wall part G from the wall part H will con
to produce the structure above described.
Having provided a piece of sheet metal and
forming it with an annular ?ange portion as B
somewhat more than twice as deep as the ?ange
or wall portion G in the ?nished closure, as illus
trated in Fig. 7, the ?rst operation thereon, as
illustrated in Fig. 8 is that of turning up from the
edge portion ll! of the flange 9 an inturned an
nular wire edge I I.
"
stitute the wall G as an e?icient cushion suffi
Then, as illustrated in Fig. 9, the wire edge II
is bumped in the direction of the top wall portion
ciently yieldable for the protection of the recep
L so that more of the material of the ?ange 9 is
tacle. The wall part G may even be dented to an
made to flow inwardly and upwardly toward the
wall L, the wire edge being in effect elongated in 20
that direction, and thereby providing a smooth
?at inner annular wall I! spaced in parallel re
lation interiorly of the outer wall or ?ange which
now constitutes the outer wall part G herein
above referred-to; 'It will be observed that the 25
inner wall i2 is of less diameter than the outer
wall so‘that the metal which flows in from the
greater circumference of the outer wall into the
less circumference of the inner wall must flow
20 appreciable extent by the blow into the space be
tween the two wall parts without the blow being
felt locally by the receptacle.
If the ornamentation of wall G is made to in
clude any bending of said wall inwardly toward
25 the wall H such inwardly bent portions may be
readily accommodated in the space between the
walls G and H.
The connecting portion of metal at the lower
annular edge of the closure, that is the connect
30 ing portion 4, rounds smoothly downwardly and
inwardly from the cylindrical portion of the wall
G and thence upwardly to merge into the lower
annular portion of the wall H. It provides a posi
tive connection between the two spaced walls and
serves as an ei?cient reinforcement against dis
tortion of either of the wall out of their true an
nular form.
'
The cross sectional arcuate curvature of the
connecting portion 4 between the cylindrical por
40 tion of the wall G and the substantially lower
most point on the portion 4, that is of the portion
5, see Figs. 4 to 6, is substantially constant at all
points around the circumference of the skirt,
thereby presenting a smoothly rounding lower .
45 corner for the wall G as viewed from exteriorly of
the closure. There is no evidence whatever pres
ent exteriorly of the closure concerning the ex
istence of the threaded interior surface of the
closure.
The cross sectional arcuate curvature of the
50
portion 4 from said lowermost point inwardly and
upwardly of the closure, that is of the portion 6,
see Fig. 4, is substantially equal to the cross sec
tional arcuate curvature above mentioned of the
55 portion 5, except where said inner portion is bent
in the formation of the threads 3, as clearly il
lustrated in the drawing, Figs. 2 and 4 to 6, Fig.
4 showing the normal contour of the portions 5
and 6, Figs. 5 and 6 showing the portion 5 un
60 changed but showing the portion of metal re
ferred to as the portion 6 now bent up in the for
mation of the threads 3 wholly within the inner
portion of the closure and concealed from vision
exteriorly of the closure.
The upper annular edge portion of the wall
65
part H is turned outwardly to provide a ?aring
together or upset as the outer wall is rolled in 30
wardly, to accommodate the same amount of
metal in a less circumference- This, it would
seem probable, results in a slight thickening of
the inner wall but such thickening is impercepti
ble and the foregoing is merely theoretical as to
what takes place. This bumping operation may
be accomplished in a suitable manner, for in
stance, of so curving the bumping die used in the
formation of the wire edge II that it will cause
the extreme edge of the metal forming the wire 40
edge to face toward and impinge directly against
the inner surface of the flange 9 when the wire
edge is completed. The edge of the metal forming
the wire edge will in this way be caused to slide -
along the surface 9, instead of curling round and 45
round, as the bumping operation is continued.
Then the material of the portion I 2 is bent to
form spiral corrugations therein serving as con
tinuous threads interiorly of the closure, thereby
completing the inner threaded wall H herein
above referred to.
The manner of bending the wall i2 to form the
threads therein is clearly indicated in the draw
ing Figs. 10 to 12. The method here illustrated
includes the use of a die roller mounted to rotate 55
freely upon a spindle l4 carried by a slide mem
ber I5 so as to be capable of traversing the wall
l2 in a direction toward and away from the top
wall of the closure as best indicated by reference
to the full and dotted line positions of the roller 60
_l3 as pictured in Fig. 12.
'
The closure is mounted in a suitable carrier l6
so as to rotate with said carrier and is intended
to be rotated ?rst in one direction for a given dis
tance and then backwardly in the opposite direc- 65
tion. Mounted upon the spindle ll of carrier I6
?ange as at ‘i so that the raw edge as 8 of the
is shown a gear is and a suitable lost-motion
metal is presented facing approximately toward,
connection is provided between the carrier and
and sometime engaging against, the inner sur
the gear, as for instance by means of a pin l9
connected with the gear and engaging within a
70 face of the wall part G.
The ?ange portion ‘iv is of course rigidly con
nected with the upper annular marginal part of
wall H and, by its ?aring disposition consti
tutes an efficient reinforcement for the upper
75 portion of said wall H against distortion out of
loose slot 20 formed upon the carrier, the carrier
and the gear having free rotary movement with
respect to each other about the axis of spindle H
within the limits of movement of the pin I! with
in the slot 20.

Meshing with the gear I8 is a second gear 2|
than it would be called upon if the full size of
which is rotatably mounted upon a threaded. thread groove were ‘completed during this travel
shaft 22. The shaft 22 is non-rotatably but lon
of the roller. Less strain is‘placed upon the ma
gitudinally slidably mounted in suitable bearings terial of the wall I2 and a sharper and more
as 23 and 24 and the gear 2| is interiorly thread
clean cut bend of said material is obtained so
ed to mate the threads of the shaft so that the that when the thread is completed it is of good
shaft will be caused to travel longitudinally with
form and adequately prominent to maintain a

the gear 2| and '?rst in one direction and then in lug of the receptacle.

10 the opposite direction according to the direction
of rotation of the gear 2|.
\ The slide member ‘I5 is ?xed rigidly upon the
shaft 22 to move back and forth therewith at all
times.
15
.
q
.
_
At 25 is shown a suitable power supply which
it will be understood is of a character to rotate
the gear I3 back and forth a proper distance in
_ each direction.
.
\
The ratio of the gears I3 and 2| and the pitch
of the threads of shaft 22 is usually, although
‘ , ,not necessarily, such that approximately one
complete rotation of the receptacle closure will
be su?‘lcient to cause the roller I3 to move in
wardly sufficiently to traverse the entire width
of the wall I2, a similar reversed rotation like
wise being su?lcient to return the roller to its
original position.
'
As the roller I3 progresses inwardly from its
full line position in Fig. 12 and engages the mov
30 ing surface of the material of the closure the
roller will be thereby made to rotate by friction
and to meanwhile bend or dent a pathway for
itself along the wall I2. After the roller has
reached its ?nal inward position as shown by
35 the dotted lines in Fig. 12 then the direction of
rotation of the receptacle closure and the direc
tion of travel of the roller is reversed, by reversal
of the drive gear 25, and the roller then retreats
backwardly along approximately the same chan
40 nel or thread groove which it formed in entering.
During the time while the roller was entering
the receptacle closure the pin I3 was bearing
against the end wall 26 of the slot 2|] and con
tinued to so bear until the inward limit was
45 reached and the driver 25 was reversed. At the
moment of reversal the pin I3 left the wall 26
and travelled the length of the slot 20 into en
gagement with the opposite end wall as 21 of
said slot before beginning reversed rotation of
50 the carrier IS. A period of rest for the carrier
I3,'and hence for the receptacle closure, occurred
during which the roller I3 was moving outwardly.
From this it will be seen that the roller I3, in
stead of retracing outwardly the exact same
groove which it formed along the wall I2 when
moving inwardly, now forms a substantially new
groove in so close parallelism with the ?rst groove
as to have the practical effect of broadening the
?rst groove.
This principle of forming two grooves merging
together so that in the ?nished article they
merge into a single thread groove of increased
, width is important for the reason that it pro
vides for displacement of a su?lcient amount of‘
material of the wall I2 to define an amply wide
thread groove for properly co-operating with the
thread lugs of the receptacle, only a portion of
the material of the wall I2 being displaced while
the roller travels in one direction, as illustrated
in Fig. 10, and the remainder necessary for com
The connecting portion 4 and the ?ange ‘I 10
greatly re-inforces the wall I2 against undesir
able distortion during the time while the roller
' I3 is operating thereon to form the thread groove.
It is further of importance to note that the
initial engagement of the roller I3 against the
material of the closure, that is as said roller
moves from its full line position Fig. 12 into en
gagement with the closure, the pressure of the
roller against the material of the closure is in a
direction toward the top wall L of the closure, as
well as radially outwardly of the closure, and that
due to the pressure exerted toward the top wall L
the material of the closure ?rst displaced by the
roller, is urged in the direction of the wall L
thereby preserving a, smooth and unbroken line
marking the lowermost point or edge, as 4, of
the closure. Except forthe pressure of the roller
I3 toward wall L when ?rst engaging the material
of the closure the displaced material of the clo
sure might be simply squashed radially of the
closure and result in the formation of an undu
lating or wavy line, instead of the straight line
15
20
25
30
marking the lower edge of the closure.
From the shape and manner of forming the
closure as herein disclosed it will be apparent 35
that any enamel or other surface ?nish as 28 oo
curring'upon the outer surface of the piece of
material forming the ?ange 9 will be carried in
wardly of the closure and occur also upon the
inner threaded surface of the wall H in the ?ne 40
ished closure, thereby giving to the closure as a
whole the appearance of being formed from solid
molded material rather than from coated sheet
metal or the like, it being noted in this connec—'
tion that the under surface of the top wall L of
the closure is usually covered and concealed by
the gasket or liner member as shown.
As many changes could be made in this con
struction without departing from the scope of the
