APPARATUS FOR POINTlÍNG CORNERS
Howard C. Underwood and Edward B. Roby,
New York, N. Y.
Application June 8, 1934, Serial No. 729,553
6 Ciaiins.
Among the principal objects which the present
invention has in view are: To provide an appa
ratus having means thereon to eliminate the
bulging or overlapping portion of material of the
5
corner of a garment and the like; to provide
means which will push inwardly the projecting
end of a corner of a garment and the like; to en
able the pointe-:l corner of a collar to assume a
uniform thickness and neatness in appearance; to
0 apply heat to the garment and the like simul
taneously with the performance of pushing the
projecting end inwardly; and to secure simplicity
of construction and operation.
in the drawing:
Figure l is an elevation of an apparatus em
bodying the features of the present invention;
Figure 2 is a tcp plan of the same shown as
taken on the line 2-2 of Figure l;
Figure 3 is a sectional view in part shown as
20 taken on the line 3-3 of Figure 2;
Figure 4 is a sectional View shown as taken on
the line il il of Figure 2;
Figure 5 is a plan view of a collar in part show
ing one corner of the collar as projecting out
wardly;
Fogure 6 is a similar view and showing the pro
jecting end of the corner of the collar pushed in
and under the folded margin end; and
Figure 7 is a sectional view of the same shown
30 as taken on the line 'l-‘i of Figure 6,
As seen in the drawing, attention is called to the
fact that we utilize an apparatus having a stand
ard i5 terminating in a head i8 providing for a
5

vertical slideway il’ for a plunger i3. The stand
ard furthermore provides a bed i9 positioned
below and away from the plunger and adapted to
support a forming die 2t, and the plunger i8
carries a pressure die 2l for exerting pressure
on the forming die with a garment or the like in
place thereon. Operation of the pressure die 2|
is obtained by any suitable means (not shown)
but conveniently by employment of the means
as illustrated in Patent No. 1,934,209 of November
'7, 1933. However, such a means may conveniently
be connected to a second class lever 22, an inter
mediate part of which engages the upper end of
the plunger I8. One end of this lever may have
suitably connected to it, a link 23, by which power
is applied, Whereas the other end is fulcrumed as
at 24 in a bracket 25 forming part of the head of
the apparatus. Preferably lever 22 provides a
long arm between the plunger i8 and the connec
tion of the link 23, and provides a short arm be
tween the plunger and the iulcrum 24, so that a
moderate pressure exerted by the operator may
(Cl. 223-2)
apply a considerable pressure to the plunger and
the pressure die 2! and the forming die 2l). The
lower end of link 23 is shown pivoted in a first
class lever 26 pivoted at 2l and forming part of the
power applying means to the treadle (not shown) 5
in accordance with the illustration of Patent
Number 1,934,209 aforesaid.
Preferably the forming die 2% is composed of a
relatively fixed die section 2B secured as by bolts
29 to the bed i9 and providing a forward face 36
against which the end edge of a collar or the like
3i may be brought into engagement while resting
flatv/ise on the bed. The said forming die further
more provides a slidable die section 32 which like
wise rests upon the bed and may slide toward and
away from the iiXed die section Z8 normal to the
said face Sli. The slidable die section has an end
iace 33 normal to the bed and at an acute angle
with respect to face Sli corresponding to the de
sired angle of the intersecting edges of the gar
ment or collar being formed.
lin order to slide this slidable die section 32, the
v
same is shown as having a guiding tongue 34
passing through a corresponding slot in the fixed
die section 2€?. A compression spring 35 is posi- .
tioned within a suitable socket, a part ¿it of which
is within the slidable die section and a part 3l of
which is within the iiXed die section, said parts
of the socket being alined and thereby enabling
the spring to be positioned therein and force the
slidable die section normally away from the ñxed
die section.
A suitable cam is provided to counteract the
spring action and move the slidable die section
32 toward the ñXed die section §28. As here 3
shown, one example of such a cam comprises a
stem i223 slidable axially parallel to the direction
oi movement of the plunger i3. Said stein passes
vertically through the iiXed die section, the
tongue
of the slidable die section and through
the bed iii. The p-art of the stem which passes
through these several elements when in normal
position, is of reduced diameter thereby pro
viding a shank 39 loosely traversing said elements
and forming a stop to limit outward movement
of the -slidable die section as clearly shown in
Figure 4.
'
As the stem 38 is lowered, a tapered enlarge
ment et thereof enters the several holes in the
ñxed die section 2S, slidable die section 32, and
bed lil, causing said holes to become axially co
incident by virtue of the enlargement ¿it taper
ing to a full diameter of the stem equal to the
diameter of the holes. The slidable die section
is accordingly moved rearwardly. This move 55

ment is preferably obtained by depression of the
same treadle which operates the plunger I8, and
as here shown, the lower end of stem 38 extends
laterally as at 4l and is engaged in the end of
CR first-class lever 26. This construction is illustra
tive of any suitable means for securing simul
taneous operation of the slidable die section and
the pressure die 2l. It may further be noted
that the upper end of the stem 38 may be stead
10 ied and guided by passing through a bracket 42
fixed upon the fixed die section 28.
'I‘he sloping face 33 of the slidable die section
32 next the corner thereof toward the fixed die
section 28 is provided with a protruding lip 43,
said lip being flatwise with respect to the bed I9
and slightly elevated above the same to permit
a folded thickness of the garment material to
enter thereunder.
It is very usual, in formation of acute-angle
20 corners in garments for the hem or fold to pres
ent an undesired protrusion of the material, as
shown in Fig. 5, and in operation of the appa
and elevated from the lower face of the slidable
section and the compression die having a cut
out portion to receive the lip throughout its
height, and a longitudinally movable stem hav
ing a cam portion for actuating the slidable sec
tion of the forming die and causing said lip to
approach and effect a pressure toward the ñxed
section in use.
4. An apparatus as characterized comprising a
forming die having a fixed section and a slidable 10
section, said slidable section having a laterally
protruding lip thereon directed toward the fixed
section, a compression die having a notch corre
sponding to the said lip for avoiding direct en
gagement therewith, and means for actuating
the slidable section of the forming die and caus
ing said lip to approach and effect a pressure
toward the fixed section in use.
5. An apparatus as characterized comprising a
standard having a bed providing a forming die
thereon, said forming die having a fixed section
and a slidable section, said slidable section hav
ratus above described, that protruding portion
ing a laterally protruding lip thereon directed
of material is engaged by the lip 43, and when
25 the lip is slid, is thereby forced inwardly of the
edge of the garment, as shown in Figure 6.
When once forced in, this corner of the material
remains tucked in, particularly since the pressure
die 2l is also functioning, preferably with a si
30 multaneous application of heat, upon the corner
of the garment. The pressure die 2| is, however,
toward the iixed section, a compression die hav
ing a cut-out portion corresponding to the said
notched, as at 44 so as not to overlie the tongue
but so close thereto as to enable the applied
pressure to be effective upon the tucked-in por
tion of the material.
We claim:
.
1. An apparatus as characterized comprising a
forming die having a ñxed section and a slid
able section, said slidable section having a lat
40 erally protruding lip thereon directed toward the
ñXed section, a compression die, said lip being
