Office of the Commissioners of Patents, with his Petition, on the
3rd October 1874.-A communication from abroad by Reuben Mann
Rose, of Williamsburgh, in the City of Brooklyn, and State of New
York, United States of America.
I, HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN EMBROIDERY
ATTACHMENTS APPLICABLE TO SEWING MACHINES," to be as follows:-
This Invention relates to embroidery attachments for sewing machines,
which attachments operate to lay an embroidery thread upon the
upper surface of the fabric, the same being secured by an independent
sewing thread. For this purpose two needles and a shuttle, or their
equivalents, are employed.
The embroidery stitch made by this mechanism is a well known one,
the same consisting of a succession of coils, which the sewing thread is
made to interlace, to accomplish which the Invention admits of ordinary
needles being used. To these ends the Invention generally consists in

page_text: a presser foot attachment, which may be applied to any ordinary sewing
machine in place of the usual foot, and has combined with it a hori-
zontally reciprocating eye, pointed needle, and mechanism for operating
the same by the sewing needle bar, so that the embroidery thread, which
is carried by the horizontal needle, is first worked by the latter in front
of the sewing needle, then moved laterally by a positive motion applied
to the horizontal needle that is thus thrown back of the sewing needle
during the ascent of the latter and across its path, and subsequently
returned laterally to its normal position, while the sewing needle in its
descent enters the loop of the embroidery thread, which is preferably
temporarily held open for such purpose by a loop detainer, and which
by the reciprocating action of the horizontal needle in line of the feed
and its lateral action combined is coiled as it were around the sewing
needle.
The presser foot is provided on its upper surface with a horizontal
slide, which has attached to it in the rear the horizontal spring or elastic
eye pointed needle for carrying the embroidery thread.
The reciprocating action of the horizontal needle in line of the feed is
effected by a bell-cranked lever, the one arm of which is connected with
the slide, and the other preferably by a cord or its equivalent with the
vertical needle bar. The reverse movement of the lever, which draws
the horizontal needle back as the sewing needle makes its descent, may
be effected by means of a spring or by a positive motion. The lateral
throw or movement of the horizontal needle back of the sewing needle,
as the latter completes its ascent, is effected by cranking the needle stem
and causing it to work through a guide connected with the presser
foot.
In some cases, especially when it is required to make sharp angular
turns of the embroidery stitch or pattern, the slide has connected with
it a detainer of the loop of the embroidery thread to hold the loop open
while the sewing needle with its thread is passing through it. This
detainer is pivotted to the presser foot and worked by a pin taking into
a longitudinal slot formed in the slide.
