PROVISIONAL SPECIFICATION.
An Improved Stop Motion for Fanning Machines or Sewing
Machines.
EDWARD CHARLES BEAN 68 Cressy Road off Sultan Road Landport Portsmouth
Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide an improved stop motion for making fans
on corsets.
The invention relates to a mechanical arrangement whereby an operator may stop
or start the machine instantaneously without noise or concussion, or make four, five,
or eight stitches or make nine seven four or one or any number at the option of the
operator.
According to my invention I provide a cylinder with a flange bracket_Fig. 1,
letter E, so arranged as to fit on the end of arm of any sewing machine. The said
cylinder F, Fig. 1, being recessed to receive a piston or spindle with a stop collar,
coned at the upper end B. 1. Fig. 1. At the other extremity I cut a thread and fit
two lock nuts for the purpose of fixing a rod between the two. The said rol is carried
down and adjusted to a treadle. To complete the action of the said spindle I insert
a spiral spring shewn in Fig. 3. Letter D, Fig. 1 is an ordinary loose pulley.
Letter G, Fig. 1 is a low spring so arranged to keep the pulley D. Fig. 1 pressed
against the cam wheel C, Fig. 1. Letter H, Fig. 1 is an ordinary steel nut with set
screw for the purpose of adjusting the bow spring G. to the face of the driving wheel D.
Fig. 3 shews the stop motion in section. Fig. 4 shews plan of same.
The action of the stop motion is as follows. When the machinist presses her foot
on the treadle the spindle K. withdraws from the notch B. Fig. 2. So long as the
foot keeps the treadle depressed, the cam wheel C. continues to revolve.
When the
pressure is relieved from the treadle, the spindle K. Fig. 2 rises and catches in
notch B., instantaneously stopping machine without concussion. The notch in cam
wheel C, letter A, Fig. 2 is for the purpose of stopping the machine with the needle
down in the material so as to make the said needle act as a pivot. The idea being to.
give a seamer greater facility in arranging the edge of seams in seaming corsets
together. When the stop motion is used for fanning purposes in stay manufacturing
the notch B. Fig. 2 is arranged so that the needle and pressure foot will rise and stop
at of an inch or at any reasonable height above the cloth plate, thereby enabling
the operator to shift her work in any desired direction.

An Improved Stop Motion for Fanning Machines or Sewing
Machines.
1 EDWARD CHARLES BEAN of 68 Cressy Road, Landport, Portsmouth, in the
County of Southampton, Mechanical Engineer do hereby declare the nature of
this invention and in what manner the saine is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of this invention is to provide an improved stop motion for making fans
on corsets or other goods where fancy stitching is required.
The invention relates to a mechanical arrangement whereby an operator may stop
or start the machine instantaneously or work the machine continuously without
noise or concussion, or make any number of fancy stitches at the option of the
operator.

page_text: The drawing referred to is that furnished with the Provisional Specification.
According to my invention I provide a cylinder with a flanged bracket, Fig. 1,
letter E, which can be so arranged as to fit on the arm of any sewing or other
nachine, the said cylinder being recessed to receive a piston or spindle with a stop
collar; the said piston or spindle being coned at the upper end B, Fig. 1. On the
lower end I cut a thread & fit two lock nuts for the purpose of fixing a rod K. Fig. 1
between the two, the said rod being carried down and adjusted to a treadle. To
complete the mechanism of the said piston or spindle I fit round it a spiral spring
shown in Fig. 3. Letter D. Fig. 1 is an ordinary loose pulley. Letter G. Fig. 1 is
a bow spring so arranged as to keep the pulley D. Fig. 1 pressed against the cam
wheel. Fig. 1, the cam wheel C. being fixed to the shaft. Letter H. Fig. 1 is a
steel nut with a set screw for the purpose of adjusting the bow spring G. to the face
of the driving wheel D. Letter A. Fig. 2 is an interchangeable piece (fixed with two
screws,) which can be fixed either in the notch B. or A. When it is fixed in the
notch B. the spindle B' rises and catches in the notch A. thereby stopping the
machine with the needle down in the material. When it is fixed in the notch A. as
shown on the drawing the spindle B' rises and catches in the notch B. thereby
stopping the machine with the needle about of an inch above the cloth plate.
Between the cam wheel C. and the driving wheel D. Fig. 1 I insert a disc of
anhydrous leather, buffalo hide or other suitable material. Fig. 3 shows the stop
motion in section, & Fig. 4 shows plan of same.
The action of the stop motion is as follows:-
When the machinist presses his or her foot on the treadle the piston or spindle B¹
withdraws from the notch B. Fig. 2. So long as the treadle is kept depressed the
cam wheel C. continues to revolve. When the pressure is relieved from the treadle
the spindle B Fig. 2 rises and catches in the notch B. instantaneously stopping the
machine without concussion.
The notch in the cam wheel . letter A. Fig. 2 is for the purpose of stopping the
machine with the needle down in the material, so as to make the said needle act as
a pivot when the pressure foot is automatically raised from the material, the idea being
to give a seamstress greater facility in arranging the edges of the material in seaming
corsets or other goods.
When the stop motion is used for fanning purposes or fancy stitching the notch B.
Fig. 2 is so arranged that the needle and pressure foot will rise and stop at of an inch
or at any reasonable height above the cloth plate, thereby enabling the operator to
shift her work in any desired direction.
Having now particularly described & ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In a stop motion with a flanged bracket letter E. Fig. I to be so arranged as to
fit on the arm of any sewing machine.
2. In a stop motion having a cylinder letter F. Fig. 1 being recessed to receive a
spindle B' in combination with a spiral spring shown in section Fig. 3.
3. In a stop motion for sewing machines working in combination with cam wheel C,
anhydrous leather disc (working between cam wheel C and driving wheel D.) driving
wheel D, bow spring G, and adjustable steel nut H.
4. In a stop motion for fanning machines having a spindle B' Fig. 2 coned at the
upper end and fitted in the notch B. or in the notch A cam wheel C. Fig. 2, the lower
end of spindle B¹ having a thread cut on same & fitted with two lock nuts in combi-
nation with a rod & treadle.
5. In a stop motion for working in combination with a fixed cam wheel having two
notches A & B, and interchangeable piece A. cam wheel C. Fig. 2.
