COMPLETE SPECIFICATION filed by the said George. Haseltine at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 23rd October 1866, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM, THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 8, Southampton
Buildings,. Chancery, Lane, in the County of Middlesex,. Civil Engineer,
send greeting..
WHEREAS, I am in possession of an Invention for "IMPROVEMENTS IN
SEWING MACHINERY," 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

page_text: from abroad by Henry William Fuller, of the City, County, and State of
New York, United States of America.
NOW KNOW YE, that I, the said George Haseltine, 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 Drawings making a part of this
Specification:-
The said Invention relates to an attachment for sewing machines invented
by John Jay Sibley, for which Letters Patent were granted to me, bearing
date the Seventeenth day of June, in the year of our Lord One thousand
eight hundred and sixty-five, Number 1641, the said attachment being
designed as an addition to the well-known "Wheeler and Wilson" machine
originally Patented by Auguste Edouard Loradoux Bellford, on the Sixth
day of October, in the year of our Lord. One thousand eight hundred and
fifty-two, Number 251, parts of which said machine as now constructed are
shown in the Drawings in order that the nature and operation of my present
Invention may be more clearly understood. With this attachment double-loop
or three or more thread stitches. can be made by the said "Wheeler and
Wilson machine, and my improvements consist in so combining the said
attachment with the cloth plate employed that the ordinary ring slide of a
"Wheeler and Wilson" machine may be used instead of the ring slide
described in the Specification of my said former Patent.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a view of the under side of the cloth plate with my improve-
ments attached. Figure 2 is a side elevation of parts of a "Wheeler and
Wilson" sewing machine provided with the attachment. Figure 3 represents
detached portions of the same. Like letters refer to corresponding parts in
each of the Figures.
A is the cloth plate; B, the frame; C, the cam lever; D, the thread carrier
lever; E, the stud connecting these levers and on which they turn; F, the
spiral spring; G, the eccentric regulating the throw of lever D; H, the
thread carrier; I, the slud on which the thread carrier turns; K, the
projection on the end of lever D; L, the under thread tension.
The object of this Invention is effected by securing frame B of the attach-
ment permanently to cloth plate A in any way preferred, so that thread carrier
H shall be in a proper relative position to the needle. The feed cam of the
'machine operates lever C, which actuates lever D, and throws out thread
:

page_text: carrier Hafter its loop is around the loop of needle thread, and spring F
returns it to spread the loop for the needle in its descent to pass through, the
operation being the same as described in the Specification of John Jay
Sibley's Invention above mentioned. When a three or more thread stitch is
made the bobbin of course is filled. Frame B may be dispensed with by
altering stud E so as to secure the proper operation of the levers and attaching
thread carrier H directly to the cloth plate. The result will be the same,
videlicet, a greater simplicity and surer operation of the parts, and dis-
pensing with the ring slide of the attachment to take the place of the ordinary
ring slide of a "Wheeler and Wilson" machine. There is also a great con-
venience in changing from the three thread to the ordinary lock stitch,
and vice versa, without unthreading the thread carrier; all that is necessary.
is to throw it out of position, as shown by the lines in Figure 1.
Having now fully described the said Invention as communicated to me
by my foreign correspondent, and shewn how the same may be conveniently
and advantageously carried into practice, I claim, the combination of the
attachment described with the cloth plate, needle, rotating hook, bobbin, ring
slide, and other operative parts of a "Wheeler and Wilson" sewing machine
constructed and operating together substantially as and for the purposes set
forth.
In witness whereof, I, the said George Haseltine, have hereunto
set my hand and seal, this Twenty-second day of October, in the
T
