In accordance with the present invention, a
base plate ii] is provided which is secured to the
base 9 of the machine by suitable means, as by
the folder may be secured in any suitable man
a set screw H, which extends through the base
thereof may be varied so as to effect the desired
plate it into a tapped hole in said base. The
base plate ill carries a bracket 62 to which a
fold in the material.
folder i3 is secured by means of an arm ill hav
10 ing an elongated slot it through which a set,
screw it extends into the bracket 52.
The folder is, as illustrated more in detail in
Figures 3 to 10 inclusive, may be made of sheet
metal which is bent to form a bottom to, top 25,
15 and sides 22 (Figure 5) having a concave chan
nel 23 therebetween which is adapted to receive
the trimming 24. In successive sections from
the mouth to the throat ‘of the folder, illustrated
in Figures 6 to 10 respectively, the sides 22 are
20 bent over in an increasing roll so as to fold the
trimming about its longitudinal axis into a gen
eral U-shape with the edges folded over inward
ly to form two plies on each side.
The approximate position of the trimming 2d
25 at the various sections of the folder is illustrated
in Figures 5, 6 and ‘7a to 10a. It will be noted
that the trimming 26 is bent into slightly con
cave format the mouth of the folder, as illus
trated in Figures 5 and 6, and that as it proceeds
30 through the folder the two edges of ' the trimming
are bent over on the inside to form inner plies
2E‘ and 26 and outer plies 27 and 28. -As the
trimming is discharged from the throat of the
folder, the two innoer plies 25 and 26 are dis
35 posed ‘adjacent each other between the folds
formed by the outer plies 2'? and 28. For reasons
explained hereafter, the exposed edge of the fold
°formed by plies 25 and 28 extends beyond theaex
posed edge of the fold formed by plies 25 and 2?.

the folder. A guide plate 4! is also carried in
the folder for properly positioning the trimming
therein. It is to be understood that the parts of
A fabric guide 33 is mounted on the folder
near the throat thereof, as indicated in Figures
3 and 9. This fabric guide comprises upper and
lower members 3! and 32 respectively which are
adapted to guide a fabric 33 and to fold the edge
45 of the fabric downwardly to_ form a ply 36 be
tween the inner plies 23 and 26 of the trimming.
As the fabric and trimming emerge from the
throat of the folder, they 'are in the form illus
trated in Figure 10a, with the ply 3d of the fabric
33 folded downwardly against the inner ply 25 of
the trimming. As the fabric and trimming to--v
gether pass under the presser foot, they are
folded downwardly, as shown in Figure 11, with
the ply 34 of the fabric secured between the ad
55 jacent inner plies 25 and 26 of the trimming"
and with the fabric lying ?at over the outer ply
21 of the trimmings In this relative position, the
fabric and trimming are passed under the needle
ner, as by solder, ‘and that the particular shape
.
~
Itis obvious that, if a wider trimming is used,
the edges will be rolled over to form more than
two plies, and the invention is accordingly not 10
limited to the use of two plies. It is also obvious
that a ?ller (not shown) may be fed in between ’
the folds of the trimming if a puffed effect is
desired.
The mechanism above described provides a 15
concealed edge trimming which is secured at the
edge of the fabric and in which the exposed edge
of the fold formed by plies 26 and 28 extends
beyond the exposed edge of- the fold formed by
plies 25 and 27, as illustrated in Figure 13. In 20
certain instances, however, a scalloped or purled
edge trimming may be desired. This may be
readily made in accordance with the present in
vention by providing a ?nger 132 (Figures 1 and
12) which extends transversely of the path of 25
feed of the material and is located in advance of
the presser foot 5 and in advance of the path of
the needle 35. The ?nger £32 is mounted on an
arm 43 which is carried by a rod M. The rod 44
may be held in a suitable bracket 45 carried by 30
the base plate i6 and may be held normally in a
position such that the ?nger 132 is retracted, by
means of a spring 46 seated between the bracket
135 and a collar 4? mounted on the rod 44. A
guide 48 may be attached to the base‘ plate ill 35
to guide the arm £53 for reciprocating movement
in a direction transverse to the path of feed of
the material. The rod 44 may be actuated by
any suitable mechanism which operates in syn
chronism with the needle 35 for causing the fin
ger 42 to‘periodically engage the edge' of the
material adjacent the path of the needle and to
press said edge in a transverse direction a suf
?cient distance past the needle path to cause a
stitch 50 to extend entirely over the edge, as 45
shown in Figures 1, 12 and 19. A particular type
of control mechanism which may be used for
causing this reciprocating movement of the rod
44 is described in detail in my copending appli
cation Serial No. 44,498, ?led October 11, 1935, 50
for Scalloping device. It is to be understood,
however, that the present invention is not lim
ited to the use of this particular mechanism.
It is to be noted that the movement of the
?nger 42 may be adjusted so as to cause the 55
stitch to extend entirely over the edge or to
cause the stitch to be displaced from its normal
path by any desired amount. In this way, a
scalloping having any desired characteristic may
be obtained.
60
In a further embodiment of the present inven
tion, a cord 51 may be attached to the trimming
thereof and with the various raw edges, both of , at the edge thereof (Figures 1, 12 and 17). For
this-purpose, the finger 42 is provided with a
the trimming and of the fabric, folded in and
guide 53 which is adapted to guide the cord 5| 65
65 concealed between the outer plies of the trim
ming.‘ It is to be understood that the needle 35

53 may comprise a cylindrical tube through

the various other parts of the sewing machine ' which the cord 5| feeds and which may be lo
(not shown) to form" the stitch 36 in the usual

cord 5! feeds around the edge of the ?nger and 70

A spring ?nger 40 is carried by the folder 13
under the prcsser foot 5. As the fabric and trim
adjacent the throat thereof and serves to hold

fed along the edge of the trimming. The adjust
the ply 34 of the fabric 33 and the adjacent plies
25 and 21 of the trimming in their proper posi
ment between the parts is such that the mate- ’
tion as they are discharged from the throat of rial and cord are shifted laterally by operation 75

1. In a sewing machine, a reciprocating needle
means to feed a fabric past the path of the 20
needle, a folder formed to fold a trimming mate
rial about its longitudinal axis into general U-'
shape with the edges folded inwardly to form at
varied as desired. Obviously, theedge of the
fabric may be prefolded to form more than one
ply or, in some instances, the fabric may be so
fed that the edge is disposed at the top of the
trimming instead‘ of being folded between the
plies thereof.
It is to be understood that the reverse side of
the fabric is shown in .Figures'13, 17 and 19 for
clearness. This side is at the bottom while the
trimming is being attached in the sewing ma
chine and is also ‘the concealed side during use.
As viewed from the front or exposed face, the
trimming is only'visible as a narrow edging which
projects slightly beyond the. edge of the fabric.
In some instances, it ‘may be desirable to at
tach the, trimming to the face of the fabric in
stead of to the edge thereof. This may be readily
accomplished, as illustrated in- Figure 15, by
feeding the trimming 24 and the cord 5! to the
‘needle in the manner above mentioned but by
allowing the fabric 33 to extend entirely across
the top of thefolder l3,- as indicated in" Figure
15, instead of feeding the edge of the fabric into
the fabric guide 30.‘ In this way, the trimming
.may be disposed in any desired location with re
, spect to the edge of the fabric. A trimming ap
plied in this manner is illustrated in Figure 14,
which shows the raw edges of the trimming fold
ed in and concealed and the trimmingsecured to
