IMPROVEMENTS IN AND CONNECTED WITH SEWING MACHINES
Year: 1885

page_text: I GEORGE SAWYER of 19 Queen Victoria Street, London, Manager to The White
Sewing Machine Company, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN AND CONNECTED WITH SEWING MACHINES," to be as follows:-
This invention relates to improvements in and connected with sewing machines
notably to certain feed regulation appliances and to pressure foot regulation to
enable the pressure foot to lift mechanically particularly when a braiding operation
or other work is being performed that requires to be turned without interfering
with the motion of the machine or when passing over an extra thickness such as
a seam.
For the purpose of this invention a shaft is fitted longitudinally under the work
plate in bearings. The front end of this shaft has a curved arm projecting at right
angles therefrom whose end can be brought to bear against or come in contact with
the feed foot to determine the distance of its travel and thus to regulate its feed to
the desired length of stitch this being effected by a lever on the opposite end of the
shaft which lever passes through the work plate and is provided with a screw nut
or thumb button working over.an are plate marked with a scale according to the
stitch desired.
The thumb button and marked plate are at the rear of the machine or close to
the pillar thus placing the feed regulation in a better position for the operator than
hitherto.
According to the second part of the invention a short tube or sleeve is fitted over
the leg of the presser foot and has a screw pin passing through it and also through
the front plate of the head, said screw has a pinch nut or thumb button to enable
the sleeve to be nipped at the desired part of the leg.
The short tube or sleeve has a pin projecting from it which rests upon one end of
a curved lever pivotted within the head the opposite end of said lever is acted upon
by a cam of the main shaft which throws it over so as to lift the presser foot
mechanically thus permitting the work to be turned about as in Braiding or other
work requiring other than a straight row of stitching.

I GEORGE SAWYER of 19 Queen Victoria Street, London, Manager to the White
Sewing Machine Company, do hereby declare the nature of the said invention
which has been communicated to me by The White Sewing Machine Company of
Cleveland, State of Ohio United States of America and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement:-
This invention relates to improvements in or connected with sewing machines
notably to certain feed regulation appliances and to pressure foot regulation to
enable the pressure foot to lift mechanically particularly when a braiding operation
or other work is being performed that requires to be turned without interfering
with the motion of the machine or when passing over an extra thickness such as
a seam.
'
For the purpose of this invention, which will be understood by reference to the
elevations Figures 1 and 2 and plan Figure 3 shown in the annexed drawings, &
shaft A is fitted longitudinally under the work plate B in bearings C, C. The front
end of this shaft has a curved arm D projecting at right angles therefrom whose
end can be brought to bear against or come in contact with the feed foot or attach-
ment E to determine the distance of its travel and thus to regulate its feed to the
desired length of stitch this being effected by a lever F on the opposite end of the
shaft A which lever passes through the work plate B and is provided with a screw
nut or thumb button G working over an arc plate H marked with a scale I
according to the stitch desired.
The thumb button G and marked plate H are at the rear of the machine or close
to the pillar J thus placing the feed regulation in a better position for the operator
than hitherto.
According to the second part of the invention (shown in Figures 1 and 2) a short
tube or sleeve K is fitted over the leg L of the presser foot M and has a screw pin N
passing through it and also through the front plate P of the head Q which is slotted
for the purpose has a pinch nut or thumb button R to enable the sleeve K to be
nipped at the desired part of the leg L.
The short tube or sleeve K has a pin S projecting from it which rests, when the
screw pin H is at the bottom of the slot in the front plate, upon one end of a curved
lever T pivotted within the head the opposite end of said lever Tis acted upon by
the cam or eccentric V of the main shaft (see Figure 4) which throws it over so as
to lift the presser foot M. mechanically, thus permitting the work to be turned
about as in Braiding or other work requiring other than a straight row of
stitching.
When the pinch nut R is loosened the sleeve K is free to be adjusted upon the
leg L and when the more eccentric part of the cam presses against the end T¹ of the
curved lever T the short arm W of said curved lever T comes in contact with the
pin S and raises the sleeve K and the leg L of the presser foot at every revolution
of the main shaft thus producing the desired vibratory motion.

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
1. The appliances arranged as hereinbefore described and their method of
operation for adjusting and determining the length of stitch as set forth with
reference to the first part of this Specification, with reference to Figures 1 and 2 of
the annexed drawings.
2. The appliances and their method of operation as described for moving the feed
foot mechanically as herein described and substantially as shown with reference to
the annexed drawings.
