page_text: I THOMAS SPENCER JAMES 68 Commercial Road Peckham Surrey Engineer do
hereby declare the nature of this invention to be as follows:-
My object is to provide a small pocket sewing machine weight about 4 ounces
dispensing with the ordinary shuttle or under thread, and making a secure twisted
loop stitch, producing in conjunction with my feed a machine at smaller cost and
of fewer parts than usual.
For this purpose I construct a suitable frame which may be described as the
letter Linverted thus 7 and joined at the bottom to four fifths of the letter H
placed on its side thus I, the H part forms the bearings for the crank shaft and
also forms the cloth plate in which is a hole through which the needle passes up
and down the whole of which is bent or formed from one piece of metal, at the free
end of the crank shaft. under the needle hole is a hook or loop maker, on the other
end of the shaft is the crank itself, having two throws one forming a handle, at the
side of the first or smaller throw is fastened a small excentric, and on the smaller
crank itself is placed a connecting rod, the use of all which is now to be described.
On that part of the frame formed by the inverted letter L is placed another
inverted letter L piece only a little longer on the long part thereof, this I call the
free arm and this slides up and down on the frame as aforesaid, the top of this
piece carries the reel of cotton and tension appliance, the shorter side carries the
needle, and the longer side slotted top and bottom passes down the back of, the
frame; the lower slot working on the excentric before mentioned, the upper slot
sliding on a pivot placed at the upper part of the frame, the connecting rod before
mentioned being fastened to a pivot between the two slots above mentioned; the
combination of these parts on receiving motion from the crank gives to the needle
on and through the free arm a peculiar pear shaped up and down motion, and this
motion in conjunction with a small presser foot pressing on the cloth plate
produces a very simple, cheap, easy and compact feed motion and the whole of
these parts working at the proper time one with the other and all receiving motion
from the crank aforesaid produces a very compact light and novel sewing machine.

page_text: I THOMAS SPENCER JAMES of 68 Commercial Road, Peckham in the county of
Surrey, Engineer 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 object of this invention is to provide a small pocket sewing machine
weighing about four ounces dispensing with the ordinary shuttle or under thread
and making a secure twisted loop stitch, producing in conjunction with my feed
a machine at smaller cost and of fewer parts than usual.
The accompanying drawings illustrate clearly the novel combination of parts by
which I attain my object. Figures 1, 2 and 3, are side, front end, and back end
elevations respectively, and Figure 4 is a section on line y. s. Similar letters refer
to similar parts in all of these figures.
To accomplish my object I construct a suitable frame a which may be described
as the letter L inverted thus and joined at the bottom to a piece b of the form of
four fifths of the letter H laid on its side thus ; the part 6 forms the bearings
for the crank shaft c and also forms the cloth plate d in which is a hole e through
which the needle ƒ passes up and down, the whole of which is or may be bent or
formed from one piece of metal. At the free end of the crank shaft c under the
needle hole e is a hook or loop maker g, on the other end of the shaft c is the
crank itself, having two throws one forming a handle i. At the side of
the first or smaller throw is fastened a small eccentric ; and on the smaller throw
itself is placed a connecting rod k the use of all which is now to be described. On
that part of the frame which is designated by the letter a formed by the
inverted is placed another inverted letter m only a little longer in the long
part thereof this I call the free arm m¹ and this slides up and down on the frame a
as aforesaid; the top of this piece m carries the reel of cotton and tension
appliance n the shorter side m carries the needle f and the longer side m¹ slotted
top and bottom passes down the back of the frame a, the lower slot o working on
the eccentric before mentioned the upper slot o¹ sliding on a pivot o³ placed at
the upper part of the frame a, the connecting rod k before mentioned being
fastened to a pivot k¹ between the two slots o and o¹ above named. The com-
bination of these parts on receiving motion from the crank h. gives to the needle f,
on and through the free arm m³, a peculiar pear shaped up and down motion, and
this motion in conjunction with a small presser foot p, pressing on the cloth plated,
thus produces a very simple, cheap, easy, and compact feed motion, and the whole
of these parts working at the proper time one with another, and all receiving
motion from the crank aforesaid, produces a very compact and novel sewing
machine. If desired a two or three speed gearing of any usual type may be
employed.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is
The combination of parts forming the twisted loop stitch sewing machine
arranged as herein before described and illustrated by the drawings annexed.
