"AN IMPROVED DEVICE FOR GUIDING COVERED WIRE TO BE SECURED UPON A

COMPLETE SPECIFICATION filed by the said Thomas Andrew Vyse
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 29th July 1870, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
ANDREW VYSE, junior, of the City and State of New York, United
States of America, now of No. 8, Southampton Buildings, London,
Merchant, send greeting.

page_text: WHEREAS I am in possession of an Invention for "AN IMPROVED
DEVICE FOR GUIDING COVERED WIRE TO BE SECURED UPON A FABRIC OR
SUBSTANCE IN A SEWING MACHINE," and have petitioned Her Majesty to
grant unto me, my executors, administrators, and assigns, Her Royal
Letters Patent for the same, and have made solemn Declaration that it
has been communicated to me from abroad by William T. Cook, of the
City and State of New York aforesaid.
NOW KNOW YE, that I, the said Thomas Andrew Vyse, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Drawing forming
a part of this Specification :-
This Invention relates to the construction of a combined guide and
presser foot for guiding covered wire in a sewing machine in such
manner that the said wire will be fed forward with the fabric or
substance to which it is to be secured, and will be fastened by the
needle thread to the said fabric or substance beneath the foot, the guide
being so constructed and arranged that the attachment of any
desired length of such wire to the fabric or substance may be effected
without injury to the point of the needle through contact with the
wire.
In carrying the said Invention into practice I combine with a sewing
machine presser foot a guide tube, so arranged with reference to the
needle hole or throat of the foot that the bore of the said tube passes
through or opens into such throat sufficiently on one side of the needle.
path to cause the point of the needle to take the covering of the wire
without touching the wire itself.
In the accompanying Drawing I have represented a combined sewing.
machine presser foot, and guide tube constructed according to this
Invention.
A is a side view of the said foot; B is a top view of the same; C is a
bottom view thereof; D is a longitudinal section through the wire
guiding tube; E is a transverse section through the needle throat;
F shews one end of the presser foot; G shews the other end of the same;

wire passage.
The presser foot bar a has clamped upon it the shank of the presser
foot b. At one end of this presser foot is a tubular projection c; through
this projection is a passage d of a diameter just sufficient to allow the
covered wire e to pass freely through it. This passage leads into a
groove fextending from the needle throat g to the opposite end of the
foot, and opening out at the bottom of the foot, as seen at Cand D.
The flat bottom of the presser foot adjacent to the open part of the
passage rests upon the fabric to which the wire is to be attached, and
holds the wire down upon the same. In the Drawing I have shewn the
covered wire being sewn upon a strip of plaited straw h, such as is used in
the manufacture of straw hats, but it may obviously be as readily attached
to other materials. The needle point plays vertically through the centre of
the needle hole or throat g, and the wire guiding passage d is so much on
one side of the throat (where it passes it) that the covering of the wire
projects slightly beyond the centre of the throat, or, in other words, into
the path of the needle point, the wire itself being out of the path of the
needle point. As the needle descends it carries its loop-forming thread
through the wire covering and through the fabric forming beneath the
cloth plate of the machine, the bow or loop to be interlocked with the
shuttle thread (or with the next loop of the needle thread if the machine
belongs to the single thread class), the work being fed forward after the
ascent of the needle, and preparatory to the next descent thereof.
the wire and plaited straw or other substance are thus fed along together,
the wire is fastened to the same at each stitch made by the stitch-
forming mechanism, the work being as rapidly performed as the sewing
together of plain pieces of cloth or other material in an ordinary sewing
machine.
As
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, I wish it understood that I claim,-
First. A sewing machine presser foot having formed with and pro-
jecting from its forward end a tube, the bore of which is in line (or nearly
so) with the needle hole, and having a groove on its under side whereby
a covered wire may be fed forward, so that the needle in its descent shall
pass through the covering, all substantially as set forth.

operative parts of a sewing machine, for the purpose set forth.
In witness whereof, I, the said Thomas Andrew Vyse, have
hereunto set my hand and seal, this Twenty-seventh day of
July, in the year of our Lord One thousand eight hundred and t
seventy.
