IMPROVEMENTS IN SEWING MACHINES
Year: 1873

page_text: LETTERS PATENT to Fenner Ballou Taylor, of 10, Newton Terrace,
Westbourne Grove, in the County of Middlesex, for the Invention
of "IMPROVEMENTS IN SEWING MACHINES."
PROVISIONAL SPECIFICATION left by the said Fenner Ballou Taylor
at the Office of the Commissioners of Patents, with his Petition,
on the 4th April 1873.
I, FENNER BALLOU TAYLOR, of 10, Newton Terrace, Westbourne
Grove, in the County of Middlesex, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN SEWING MACHINES," to be as
follows:-
-
My improvements relate to that class of sewing machines known as
loop-stitch machines, and have for their object the construction of a
machine which shall be lighter, more simple, and less expensive than
any good machine heretofore produced, and embrace a novel arrange-
ment for producing the feed and looping action in connection with the
motion of the needle.

page_text: In my improved machine all gearing and belts for driving are
dispensed with. The needle bar is operated by an arm rocking on a
fulcrum pin or stud. The said arm has an extension forming an elbow
crank or lever, on the lower end of which is a pin or stud provided with a
friction roller, the said stud and roller taking into a cam groove formed
on the inner surface of the driving wheel, which is arranged parallel
with the rocking arm. The rotation of the driving wheel imparts an
oscillating motion to the elbow lever, which causes the needle arm to
rock upon its fulcrum, and thus impart the necessary reciprocating
motion to the needle bar.
The hook or looper is operated by means of a rod hinged to the lower
end of the elbow lever. This rod has both a reciprocating longitudinal
motion and a lateral motion, the former being imparted to it by the
elbow lever, and the latter by means of a stud or projection working in
an oblique cam slot in a plate arranged under the cloth plate. The said
rod passes through a hole in the looper, and by its lateral motion imparts
the necessary vibratory movement to the said looper.
The feed is accomplished by the above-mentioned rod working through
a curved slot in the feed bar. The said rod gives to the feed bar an
upward, forward, and downward movement, the return movement being
imparted to the same by a spiral spring working in a longitudinal slot in
the said bar.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Fenner Ballou Taylor in the Great Seal Patont
Office on the 27th September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FENNER
BALLOU TAYLOR, of 10, Newton Terrace, Westbourne Grove, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of April, in the year a
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Fenner Ballou Taylor,
Her special licence that I, the said Fenner Ballou Taylor, my

page_text: executors, administrators, and assigns, or such others as I, the said
Fenner Ballou Taylor, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN SEWING MACHINES," upon the
condition (amongst others) that I, the said Fenner Ballou Taylor, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Scal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Fenner Ballou Taylor, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement, reference being had to the accompanying
Drawing forming a part of this Specification:-
My improvements relate to that class of sewing machines known as
loop-stitch machines, and have for their object the construction of a
machine which shall be lighter, more simple, and less expensive than
any good machine heretofore produced, and embrace a novel arrange-
ment for producing the feed and looping action in connection with the
3 motion of the needle.
In my improved machine the needle bar is operated by a rocking arm
having an extension forming an elbow crank or lever, which is provided
with a stud on which revolves a friction roller, said stud and roller
taking into a cam groove formed in the inner surface of the driving
) wheel. The hook or looper and the feeding device are both operated by
a rod hinged to the said elbow lever. The said rod has a reciprocating
longitudinal motion and a lateral motion, the former being imparted to
it by the elbow lever, and the latter by means of a stud or projection on
the said rod working in an oblique cam slot in a plate arranged under
5 the cloth plate of the machine. The said rod passes through a hole in
the looper, and by its lateral motion imparts to the said looper the

page_text: necessary vibratory movement. The feed bar has a curved slot through
which the said rod passes, and imparts to the said bar an upward,
forward, and downward movement, the return motion being effected by
a spiral spring working in a longitudinal slot in the said bar.
Figure 1 is a side clevation of my improved machine; Figure 2 is a
plan of the same with the cloth plate removed; Figure 3 is an end
elevation of the same. Like letters indicate like parts in all the
Figures.
The Drawing shows the position of the several parts when the
machine is at half stroke.
The needle bar A is operated by the arm B rocking on a fulcrum
pin b. The said arm is provided with an extension B¹ (shown partly by
dotted lines, Figure 1), which forms an elbow crank or lever. This
elbow lever is provided with a stud 6', on which turns a friction roller b",
the said stud and roller taking into a cam groove c formed in the inner
surface of the driving wheel C, which is arranged parallel with the
arm B. The driving wheel C being put in motion by the handle C¹ it
imparts an oscillating motion to the elbow lever B¹, thus causing the
arm B to rock upon its fulcrum b, and produce the vertically recipro-
cating motion of the needle bar A. The hook or looper D, pivotted to
the frame of the machine at d is operated by the rod E, which is
hinged to the elbow lever B¹ at e. This rod has two motions, a recipro-
cating longitudinal motion imparted to it by the oscillations of the
elbow lever B¹, and a lateral motion which is
projection e¹ working in an oblique cam slot
The forward end of the rod E passes through a hole in the looper D, as
shown in Figure 3, and by its lateral motion imparts to the said looper
the necessary vibratory movement on its pivot d. The feed bar G is
operated by the rod E working in the curved slot g in the said bar.
The vibratory movement of the looper D imparts to the rod E a
curvilinear motion, which causes the said rod to impart to the feed bar G
an upward, forward, and downward movement, the return movement
being effected by the spiral spring H. The portion g' of the feed bar G
works in a slot formed in the frame of the machine (see Figures 13
and 2), thus preventing any lateral displacement of the feed bar. The
given to it by a stud or
formed in the plate F.

page_text: length of stitch is regulated by the screw I, which sets against the feed
bar G, as shown in Figure 3.
In witness whereof, I, the said Fenner Ballou Taylor, have herc-
unto set my hand and seal, this Twenty-second day of September,
in the year of our Lord One thousand eight hundred and seventy-
three.
Witness,
THO8. N. PALMER.
