Mass, a corporation of Maine
Application December 18‘, 1935, Serial No. 54,999
6 Claims. (G1. 22.3—-38)
This invention relates to folding machines,
namely of that class used for the infolding of
edges of cloth blanks, as for collars, cuifs and
the like.
The invention relates more particularly to the
5
de?ning templet or die element‘of folding ma
chines, an object being to provide a templet of
general utility, having movable plates which are
15
retractible from the folds and expansible to
original or de?ning position. A particular object
is to afford a templet mechanism wherein the
de?ning plates may be retracted in readily ad
justable directions or variable angles of move
ment, and to provide for this purpose a plate
carrying and operating mechanism which is
readily adjustable and which e?ectively retracts
the plates from the folds and accurately returns
them to normal position without the lost motion
and inaccuracy that sometimes occurs, especially
with certain shapes of blank.
The invention is illustrated as applied to the
infolding of collar top blanks having a sharp or
acute angle at each of two corners, the blanks to
be folded at the two ends and along one side but,
as usual, remaining unfolded at the opposite long
side.
Examples of folding machines for the
handling of sharp corner blanks are shown in
the prior patents of W. L. Dixon No. 1,591,613 of
July 6, 1926 and No. 1,648,450 of November 8,
1927, in each of which the machine comprises
the usual bed or support for the blanks, the low
ering and rising templet or die which de?nes the
blanks on the support, the infolders moving in
wardly and outwardly to fold the blank edges
-, over the edges of the templet, usually in sequence
at the sharp corners, and means for eifecting
squeezing pressure upon the folds, preferably
between the infolders and bed and after the re
traction of the templet plates from the folds.
In these prior machines the de?ning plates are
movably supported beneath a templet body mem
ber or so-called crosshead, which is mounted to
move up and down, for example upon carrying
arms swinging from a rear axle. Said prior pat
ents show particular means of retracting the
templet plates, the end plates moving at a diago
nal angle so as to clear the end and side folds
of the blank. The present invention provides a
novel vmounting of the die plates and mechanism
for operating them to retract and expand as
described; and the illustrated arrangement per
mits the end or corner plates to be retracted at
the necessary sharp angle without the necessity
of cutting clearances at the edges of the infolder
55
plates.
Other and further objects and advantages of
the present invention will be explained in the
hereinafter following description of an illustra
tive embodiment thereof or will be understood by
those conversant with the subject. To the attain- 5
ment of such objects and advantages this inven
tion consists in the novel folding machine and
templet and the novel features of combination,
arrangement and construction herein illustrated
or described.

In the accompanying drawings-—
Figure 1 is a general side elevation of a suffi
cient portion of an infolding machine to explain
the present invention, this view being on small
scale and taken partly in section on a fore-and
15
aft vertical plane, the die or templet shown in
its lowered position, but in dotted lines raised.
Fig. 2 is an inside face view of an infolded
blank such as may be de?ned and folded with the
present invention.
20
Fig. 3 is a top plan view of the central portion
and left end of the templet of Fig. 1.
Fig. 4 is a front elevation of so much of the
templet as is shown in Fig. 3, with the blank
de?ning plates omitted.
Fig. 5 is a fore-and-aft vertical section view
looking from the right taken on the Section line
5—-5 of Fig. 3.
Fig. 6 is a similar section View taken on the
line‘ E-$ of Fig. 3 or Fig. 4.
30
Fig. '7 is an exploded View of the component
parts constituting the left end of the templet,
and representing the symmetrically similar parts
at the right end.
Fig. 8 is a partial plan view showing angular
adjustments of both adjusting disks and indicat- ‘
ing the resulting extraction movement.
The usual bed or blank support 28 is indicated,
and slidable thereover inf olders 2i suitably shaped
and operated to effect the folding of the blank
edges, in this case the rear side edge and the
left and right end edges of a blank 22'of collar
top shape, as indicated in Fig. 2.
A templet body or crosshead frame 23 is shown
as a rigid longitudinal casting attached near its
ends to a pair of carrying’ arms 24 which are
secured to a longitudinal rear axle or rockshaft
25, so that by the rocking of this axle the templet
as a whole may be lowered upon and lifted from
the blanks on the bed. A rear rock arm 26 and
link 21 may extend to a cam for this purpose,
as in said patents.
The mounting of the de?ning plates on the
crosshead is shown as follows. Underneath the
body 23 is shown a T-shape center carriage 28 55
2.
2,108,199
slidable in a transverse or fore-and-aft manner,
and at each end is an end carriage 29, mounted
under the body in a manner permitting not only
fore-and-aft movement but longitudinal or right
and left movement, thus aifording the desired
diagonal extraction. A strong spring 30 is shown
interconnecting the end carriages 29, tending to
pull them into retracted positions. The carriage
28 by its top part 233 is guided rigidly in a
10 way 28b formed in the under side of the body
23, extending fore-and-aft.
On the carriages
28 and 29 are mounted blocks 3| and 32 longitudi
nally adjustable on the carriage for size. The
block 3! carries the center templet plate or
15 section 33 while the blocks 32 carry the end sec
tions or de?ning plates 34. The complete outline
of the blank is thus aiiorded; all of the sections
are movable forwardly in unison to retract them
from the rear infold; and the end sections are
20
simultaneously retractible longitudinally, afford
ing the necessary diagonal angle to retract clean
ly from the sharp corner infolds of the folded
blank.
On the templet body or crosshead is movably
25 mounted a system of parts which undergo timed
fore-and-aft movements, a?ording the corre
sponding movements in the described carriages,
blocks and templet sections. One of these parts
is a longitudinal bar 3?, or preferably a parallel
30 pair of such bars, as shown, movable fore-and
aft in sliding contact at the under side of the
body 23. The center carriage 28 is shown at
tached ?xedly to the bars 31 so as to partake
of the fore-and-aft movements, while the end
35 carriages 29 are engaged slidab-ly therewith, so
as to partake of the fore-and-aft movements
While leaving the carriages free to slide longi
tudinally. Another member of this system is
the upper longitudinal bar or horizontal plate
40 38, spaced somewhat above the templet body
and in contacting relation above and below with
the adjusting disks 59 and 65 to be described.
These bars 31 and 38 are indirectly interconnected
with each other, as will be described, and with
45 an actuating transverse slide bar 4%], movable
fore-and-aft near the center part of the body
and extending out rearward to where, at its rear
end, it carries a forked end Iii straddling the
axle 25 and thereby guided thereon. The actu
50 ating slide bar lie is mounted upon the top of
the head by front and rear recessed guide blocks
39.
Projecting rightwardly from the actuating
bar is a pin or follower 42 engaging the groove
of a cam 43 loose on the axle 25 and movable by
55 convenient connections from, the usual main
shaft or timing mechanism to a?ord the timed
fore-and-aft movements of the bar 55 and con
sequently the retracting and expanding move
ments of the templet sections, this general plan
60 of an actuating cam at the axis of templet
swinging being well known.
The parts interconnecting the actuating bar
It!) with the longitudinal bars 3? and 38 to com
pel them to move as a system comprise the fol
65 lowing.
A block Mis set between the bars 38
and 43, with bolts 45 or other means for rigidly
but adjustably interconnecting them.
At the
front end of the bar 45 is a short upstanding
bracket Ql interconnected by a bolt 48 with a
70 block 49 upstanding from the bar 33.
bolts 45 are loosened the nuts
When
on bolt £8 may
be turned to adjust the position of bar 38 and
connected parts. The bar 38 at its ends operates
through the end mechanisms to be described to
75 move fore-and-aft the end carriages 29, which,
being grooved ‘to receive the twin bars 31 cause
the latter to shift fore-and~aft along with the
center carriage 28 to which they are bolted.
By these means the entire system comprising the
lower and upper longitudinal bars 31 and 38 is
moved forwardly to contract, and rearwardly to
expand the templet. As described the center car
riage 23 with the center de?ning plate 33 moves
fore-and-aft with this system, in a straight line;
and it new remains to describe the mounting, 10
control, and adjustment for the end carriages
23 carrying the end templet sections 34; and as
this mechanism is preferably the same at both
ends of the templet, only that at the left end will
be described.
The end carriage 29, as already described, is
slidable in both directions underneath the tem
plet body 23, being longitudinally grooved to en
gage the longitudinal bar or bars 37. When these
bars shift frontwardly with the carriages the lat- ,
ter are simultaneously given a longitudinal
movement toward the center, resulting in the
desired diagonal movement best for extraction
from the sharp corner folds. The carriage is
shown maintained in sliding contact with the
under side of the body by means of a large ver
tical stud 55 having its shouldered lower end
?xed in the carriage, and extending upwardly
through the body, which has an open recess to
permit the horizontal movements, and upwardly 30
through the adjusting disks to be described, and
through the recessed longitudinal bar 38, the
stud being provided near its top end with a
washer 55 and a stud head 57. The washer and
head may be both threaded on to the stud and
lock with each other in position to con?ne snugly
the assembled parts while permitting the hori
zontal movements.
The angle adjusting means comprises one or
preferably two disks, that may conveniently be
circular as shown. Thus, beneath the washer
is an upper disk 59 overlying the bar 38. This
has an extended radial slot 60 accommodat
ing a slide block 6| having a hole Eli. snugly
engaged by the stud 55, rather than engaging
the stud directly in the slot. The upper disk
53 may be adjusted to different radial positions
of its slot and when adjusted is secured to the
top side of the bar 38 by set screws '62 passing
through concentric slots in the disk. When ad- .
justed the disk 59 thereby becomes in e?ect a
rigid part of the fore-and-aft or transversely
moving system. The slot 59 is shown in Fig. 3
set longitudinal, so that by it the block '6! and
stud 55 are simply moved fore-and-aft, while ,,
the stud and the block, together with the carriage
23 beneath are all free for en-dwise movement
as controlled by the second or lower disk 65 next
to be described.
-
The lower disk 55 is directly above the body 23
and has a diametrical underneath slot, in which
plays a slide block 8?, near the central part or"
which is a hole 573 which the stud 55 snugly en
gages, the stud passing through a radial slot 66
at the upper part of the disk. The disk 65 and
its radial slot may be set to different diagonal
directions, being shown at a suitable slant to cause
de?ning plate extraction from certain shapes of
infolded blanks. When adjusted the disk is ?xed
to the templet body 23 by a set screw 68, its slot
thereby constituting a relatively ?xed (but ad 70
justable) slideway for the shifting of the block
6?.
The set screw passes through a concentric
slot in the lower disk and enters a threaded hole
in the body; and for access to the screw for
75

2,108,199
loosening and tightening it there are provided
openings or windows in the bar 38 and disk 59
above.
The actual retracting motion of the end or
corner templet section 34 is a diagonal resultant
When the upper disk 59, stud 55 and end car
riage move transversely frontward, the slot in the
lower disk compels the stud to move longitudi
nally inward to position 55a while the disk slide
blocks 6! and 6‘! move to 6 la and tile as indicated. '
due to the adjusted positions of the two disks,
namely the relatively ?xed lower disk 65 and the
fore-and-aft moving upper disk 59. With the
angles shown, the forward movement of the ac
tuating system, including the upper disk, causes
the stud and carriage to move frontwardly, but
the play of the block 61 in the slot 65 of the lower
disk compels a longitudinal component and thus
determines the actual diagonal retracting move
15
ment of the templet section, in this case at the
same angle as that of the slot 66, and to a dis
tance determined by that angle and by the for
ward throw of the system caused by the cam 43.
Obviously the upper disk may be adjusted angu
larly and then the retracting motion will be de
termined by the two disks, or their guide slots,
in connection with the cam throw.
The adapta
bility is practically universal and any resultant
is obtainable without need of altering the cam
43 or its throw. The large vertical stud is a sort
of axle, about which the adjustments are made,
the slides engaging the stud, and the slides sliding
in the disks, all without lost motion or appreciable
wear.
The stud and disks are normally concen
tric.
The simple forward shift by the cam re
tracts the two corner plates from the rear corners
of the blank while the center plate comes simply
forward out of the rear‘ fold of the blank.
With an excessively pointed collar top shape, or
equivalent, where the angle is abnormally sharp
this invention gives great advantage. When the
corner angle is nearly 90° the under disk can give
the necessary motion without inclining the upper
disk, the under disk delivering the full throw
caused by the front shift due to the cam 43. With
4.0 the very acute angle this would be impractical
and the adjustment of the upper disk is impor
tant. This, if the shifting system moves front
Ward a sufficient distance to retract the templet
corner plate clear from the rear blank fold, this
shift, if determined alone by the ?xed lower disk
might have to be at such a steep angle that the
templet end edge would not fully retract, and
would underlap the end infolder, even so much
as to prevent the rising of the templet from. the
blank. By adjusting the shiftable upper disk to
a proper slant in conjunction with the slant of
the under disk, this can be corrected. Thus turn
ing the upper disk slightly from longitudinal will
permit the frontward plate movement to be re
duced while yet producing the necessary. endwise
inward retraction. For example the under disk
can be set at an angle nearer to 90° and the upper
disk turned to give the desired total extent of
retraction. With a given cam throw the two
W) disks may be adjusted at the same time to afford
the necessary resultant angle and distance of
retraction to withdraw about equally from the
long rear folded edge and the short end infold,
thus clearing the infolders at both edges. In
other words to secure the proper result from the
lower disk the frontward shift need not be long
but only medium, and the upper disk set to give
the desired resultant retraction. The sharper the
blank angle the more important becomes the
modifying adjustment of the slotted upper disk.
While in Fig. 3 the upper disk is set with its
slot longitudinal and the lower disk with its slot
about 45°, Fig. 8 shows the lower disk at a steeper
angle, and the upper disk reset at a slight angle.
The direction and distance from 55 to 55a deter
mine the angular retracting movement of the
carriage and de?ning plate and the distance of
such retraction; both of which are therefore
universally adjustable to suit the conditions at 10
hand, the third factor or distance of frontward
shift caused by cam 43 being non-adjustable.
There has thus been described a folding ma
chine ful?lling the purposes of the. present in
vention and embodying its principles; butsince T‘ .
many matters of operation, combination and con
struction may be variously modi?ed within the
scope of the invention, the claims are not in
tended to be limited to such matters except to
