County of Surrey for an Invention of A NEW OR IMPROVED ARRANGEMENT
OF SEWING MACHINE
PROVISIONAL SPECIFICATION left by the said Thomas James Denne.at
the Office of the Commissioners of Patents on the 7th December 1882.
THOMAS JAMES. DENNE, of Holmesdale Red Hill, in the County of Surrey
"A NEW OR IMPROVED ARRANGEMENT OF SEWING MACHINE"
This Invention relates to a special combination of details to a frame of special
construction forming a new or improved sewing machine.
According to my Invention I form the frame of a base plate and a pillar with the
upper part carrying the arm and head in one casting the arm being hollow for the
reception of the upper shaft which passes through it from the upper pinion at
the back to the cam disc, at the front. The front part of the base plate has also
the upright for carrying the work plate and a shield within which the shuttle
works on a rod attached to the shield to support the shuttle carrier which carrier
has a direct to and fro motion through a link connected to it and to a disc on the
front end of the lower shaft, this receiving its rotation by a pinion on its back
end being geared into by the main driving wheel which is affixed to the pillar
and also gears into the upper pinion before referred to for giving it the necessary
motion.
The shuttle carrier is composed of a cradle free to run in guides fastened to the
front upright and the cradle has a curved arm whose lower end is formed as a collar'
on ferrule to slide on the rod under the action of the link.

The cam disc of the upper shaft operates the presser and feed foot the leg of
which is adjustable for length of stitch by a screw pin and suspended lever the
lower end of which presses against the opposite side of the leg to counteract a
spring fitted to press in the other direction. The cam disc of the upper shaft has the-
j

page_text: pin for working the heart shaped cam having the needle rod attached the needle
having an up and down motion in the head.
The upper end of the presser and feed foot leg is pressed upon by a plate
controlled by a helical spring the pressure of which adjustable by a thumb button
fitted on a threaded portion of same.
The two pinions and the main driving wheel are partially enclosed by a screen
fastened to the pillar and the arm carries the spool pin and thread tension
regulator the thread passing through guide eyes on the head and on the needle bar
respectively.
The work plate is provided with a removable plate, this having a bolt which can
be lifted to serve as a finger hold and to drop down behind a bar to lock the plate
in position.

According to my invention illustrated in the annexed drawings Figure 1 of
which represents a side elevation, Figure 2 a similar view looking on the opposite
side of the machine Figure 3 a front or end view Figures 4, 5, 6, 7, and 8 being
views of details.
I form the frame A of a base plate B and a pillar C with the upper part D
carrying the arm E and head F in one casting the arm E being hollow for the
reception of the upper shaft G which passes through it from the upper pinion H
Figure 4 at the back to the cam dise I at the front.

The front part of the base plate B has also the upright J for carrying the work
plate Kand a shield within which the shuttle M works on a rod N attached to
the shield to support the shuttle carrier P which carrier has a direct to and fro
motion through a link Q connected to it and to a disc R on the front end of the
lower shaft S this receiving its rotation by a pinion T on its back end being
geared into by the main driving wheel U which is affixed to the pillar Cand
also gears into the upper pinion H before referred to for giving it the necessary.

The shuttle carrier P is composed of a cradle V free to run in guides W W
fastened to the front upright and the cradle V has a curved arm X whose lower
end is formed as a collar or ferrule to slide on the rod N under the action of the
link Q.

The cam disc I (Figure 5) of the upper shaft G operates the presser and 4
feed foot Y the leg Z of which is adjustable for length of stitch by a screw pin a

page_text: and suspended lever b the lower end of which presses against the opposite side of
the leg Z to counteract a spring c fitted to press in the other direction.
The cam disc I of the upper shaft G has the pin d for working the heart shaped
cam e (Figure 6) having the needle rod f attached the needle g having an up and
down motion in the head F. The upper end of the presser and feed foot leg Z is
pressed upon by a plate h (Figure 7) controlled by a helical spring i the pressure
of which is adjustable by a thumb button j fitted on a threaded portion of same.
The two pinions H, T, and the main driving wheel U are partially enclosed by a
screen k fastened to the pillar C and the arm E carries the spool pin / and thread
tension regulator m the thread n passing through guide eyes p p¹ on the head and
on the needle bar respectively.
The work plate K is provided with a removable plate q (Figure 8) this having
a bolt r which can be lifted to serve as a finger hold and to drop down behind the
bar 8 to lock the plate in position
Having now described the nature of my said invention and in what manner the
same is to be performed I declare that I claim
The construction and arrangement of sewing machines as hereinbefore described
and as represented in the annexed drawings.
In witness whereof I the said Thomas James Denne have hereunto set my
hand and seal this Sixth day of June in the year of our Lord One
thousand eight hundred and eighty three.
