Improvements in Sewing Machines.
I, FRIEDRICH WILHELM MÜLLER, trading as F. W. Müller, Jr., of 23, Cuvry-
strasse, Berlin, S.O., in the Empire of Germany, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
The subject of this invention is a sewing machine the mechanisms of which are
brought to the highest degree of simplicity by being reduced to those parts only
which are strictly necessary. In view of the simplicity, and of the consequent
saving in cost price, the machine is adapted for use as a toy.
The invention relates to driving mechanism of the sewing machines, in addition
to which it comprises certain other distinguishing features of construction which
will be hereinafter more fully described.
In the accompanying drawing.
1
Figure 1 is a left-hand end elevation of the machine and
Figure 2a front elevation thereof, with the hand-wheel shown in section, and
Figures 3 to 6 show details.
The hand-wheel or fly-wheel a is revolvably mounted upon a pivot or spindle b
secured to the machine-frame and is fitted with an inner toothed rim c which gears
with a toothed wheel d. The wheel d is connected with the pin e of the crank
or eccentric f supported by the frame of the machine.
The rotary motion of the crank is transmitted to the lever through a curved
link g engaging the crank pin, and thus produces the up-and-down motion of
the needle bar. To the right-hand arm of the lever his pivoted a link k, the lower
extremity of which serves to set in motion a lever m operating the loop former.
The loop former is, by the said lever m, set in motion, a pin o of the said lever m
entering a curved slot in the loop former for the purpose. At the same time
as the loop-former oscillates, the cloth-feeder 2 receives motion by the operation
of the said pin o in a cam slots in the said feeder. This feeder is guided by slot t
enclosing a screw or stud u about which it oscillates and the top part of said
feeder has a toothed portion which is so shaped as to enable the looper to
raise it.
q designates the presser-foot adapted to be raised by turning round the
eccentric r.
At each revolution of the hand-wheel a the toothed wheel d performs two and
four-tenths revolutions, and, through the medium of the lever-mechanism above
described, causes the same number of stitches to be made.
The machine is worked with one thread only, without a shuttle, and produces
a single chain-stitch seam.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
A sewing machine for use by children, characterized by a lover arm having

page_text: an upward and downward motion causing a looper to oscillate and at the same
time imparting a to and fro motion to a feeder 2 which latter during its forward
motion is raised by the looper coming from the opposite direction, so enabling
it to advance the fabric.
