stantially forms a loop and is retarded thereon
as it slides downwardly toward the point of the 10
attachment. While this ?rst loop is retarded
on the attachment the thread again contacting
the attachment forms a second loop which is also
retarded and is higher up on the attachment than
the ?rst loop. When the third loop is formed

While I have shown in the accompanying
drawings a preferred embodiment of my inven
tion, yet I wish it understood that the same is
susceptible of modi?cation and change without
departing from the spirit of my invention.
Referring to the drawings, Fig. 1 is a front
elevation of the sewing machine embodying the
features of my invention. Fig. 2 is a sectional
thereof a groove 62 which acts as a guide in the
elevation showing the use of one of my stitch
changing implements; Fig. 3 is a side elevation of
the stitch changing implement shown in Fig. 2;
Fig. 4 is a front view of Fig. 3; Fig. 5 is a front
35 elevational view of my sewing machine with feed
plate in position for edge to edge sewing.
Referring more particularly to the embodiment
selected to illustrate my invention, it comprises
a feed pressure plate 49 having a slot 50 placed
40 substantially over anradjustable center guide 26.
A main drive shaft 52 suitably connected to the
upper portion I2 of the frame In and operated
by a drive wheel ‘Ill connected to motive means
has a connection 54 supporting a looper 55. Posi
45 tioned across the slot 50 is a needle 56. An at
tachment 51 is adapted to be ?tted into slot 50
formed in the upper pressure plate 49. My at
tachment has a back portion 58 which projects
slightly upwardly as indicated at 59 to ?t and
50 hold it within the corresponding portion of the
slot of the upper pressure foot 49. Continuing
integrally from the back portion 58 my attach
ment has a slight downward and inward slope
and tapers to a point 60 at its front end. This
construction of my attachment determines in its
20
tachment on either side are a pair of downwardly
feeding of the goods laid ?at edge to edge on an
upper plate 63. Said groove 62 is placed over 25
the guide member 26 and cooperates therewith
in guiding the adjacent edges of material on
either side thereof and limiting the upward pro
jection of the edges of the material when being
fed through the machine. An upper plate 63 is 30
removably attached to a lower plate 64 ?xed to
the lower bed I l by suitable means such as screws
or the like 65. Said upper plate 63 forms a level
surface‘for goods for sewing purposes and par
ticularly where two pieces of goods are to be
sewed together edge to edge. This upper plate
63 cooperates with the groove 62 in my attach
ment 51 to give even feeding, a?ord accurate
edge to edge sewing, and to prevent bunching of.
either or both edges of the two pieces to be sewn.
In feeding the materials to be sewed together edge
to edge, said materials are fed with their oppo
site edges slightly upturned, and the ?anges 6|
forming groove 62 of my attachment 5'! maintain
the slightly vertically projected edges. As the
materials pass said groove 62 and contact center
guide 26, said center guide separates the edges
of the materials and retains each of said edges
in vertical position for the passage of the needle
therethrough. My attachment 5'! thus has the 1
double feature of determining the style of stitch
as well as forming a guide member to insure
proper edge to edge sewing.
One of the purposes of my sewing machine is
to sew a stitch not shown on the opposite side of
2,105,856
the material. Another purpose is to sew a stitch,
a serging or overcast stitch to ?nish the edge of
the goods. A third purpose is to sew two pieces
edge to edge each fed ?at, and make an over
hand stitch in place of the zig zag stitch here
tofore known in the art. My device is useful in
sewing furs and other materials edge to edge.
