the Office of the Commissioners of Patents, with his Petition, on the
24th May 1867.-A communication from abroad by Louis Morris,
residing at Broadway, New York, United States of America.
I, GEORGE TOMLINSON BOUSFIELD, of Loughborough Park, Brixton, in the
County of Surrey, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN BRAIDERS OR EMBROIDERING APPARATUS TO BE USED
SEWING MACHINES," to be as follows:-
This Invention has for its object improvements in braiders or embroidering
apparatus to be used with sewing machines when it is desired to employ the
same for embroidering cloth or other fabrics or materials; for this purpose the
apparatus is formed with a clamp, by which it can be clamped to the presser
bar or other suitable part of a sewing machine. The clamp carries a plate or
frame, to which is pivotted a vibrating arm which bangs vertically, or nearly
so, the pivot being placed intermediate of the length of the arm; in the lower
end of the arm is an eye, through which the embroidering thread or braid is
led; the upper and lower ends of the vibrating arm are each curved over into
the path of the arm that carries the needle, so that as the needle arm rises
and falls a projection upon it may strike against the curved ends of the
vibrating arm and so turn it upon its pivot. When the needle arm ascends it
strikes against the curved upper end of the vibrating arm and causes its lower
end to advance towards and past the needle, and it then passes between the
needle and its thread below the eye. When the needle descends the needlo

page_text: arm turns the vibrating arm back towards its former position, and thereby
causes a loop of its cord to be left in an advanced position or thrown out, the
said loop being held in proper position for the needle to pass through it by a
curved spring attached in an inclined direction to the outside of the lower part
of the vibrating arm; the upper end of said spring is fixed to the vibrating
arm, and its lower end is free and has on its inner face a point which rests against
the lower end of the curved arm. When the needle descends its point enters
between the vibrating arm and the spring and enters the loop of twist. Before
the needle has completed its descent the end of the needle arm strikes against
the curved lower end of the arm and moves it back to its former position,
leaving the needle in the loop of embroidery, thread, or twist (which loop is
completed by this movement), the spring point giving way before the needle
and allowing the bar and spring to move back and clear themselves of the
needle, which when its own thread is secured by the shuttle thread or by
other means rises out of the embroidery loop, and the end of the needle arm
comes up against the curved upper end of arm and again vibrates it so as to
move its lower end towards the needle, as before described, when a fresh loop or
bend of the embroidery thread or twist is again brought into position to be
secured on the surface of the cloth by the next descent and stitch of the needle.
The eye or hole in the vibrating arm, through which is passed the embroidering
thread or cord is just behind the place where the spring point bears against
the said arm; by this means each succeeding upward and downward move-
ment of the needle causes a twisted coil or loop of the embroidery thread to
be formed on the surface of the cloth, which coil is then fastened to the cloth
by the stitches successively.
