PROVISIONAL SPECIFICATION left by Alfred Vincent Newton at the
Office of the Commissioners of Patents, with his Petition, on the
4th April 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, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN EM-
BROIDERY 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. Two needles and a shuttle or their equivalents are employed for
this purpose. 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 a presser foot attachment, which may be applied to any
ordinary sewing machine in place of the usual foot, and has combined

page_text: with it a horizontally 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.
As 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
a longitudinal slot formed in the slide.
