page_text: LETTERS PATENT to James Yates, of the Town and County of the Town of
"IMPROVEMENTS IN MACHINERY AND
Nottingham, for the Invention of
APPARATUS FOR EMBROIDERING FINISHED HOSIERY OR OTHER TUBULAR
FABRICS OR MATERIALS."
Sealed the 16th February 1877, and dated the 2nd December 1876.
PROVISIONAL SPECIFICATION left by the said James Yates at the Office
of the Commissioners of Patents on the 2nd December 1876.
" IMPROVE-
JAMES YATES, of the Town and County of the Town of Nottingham.
MENTS IN MACHINERY AND APPARATUS FOR EMBROIDERING FINISHED HOSIERY OR
OTHER TUBULAR FABRICS OR MATERIALS."
I employ a Bonnaz embroidering machine, or a machine of similar construction,
and cut away the platform of the machine upon each side of the needle disc in the
direction of the length of the machine, thereby forming a narrow bed, upon which
a tubular fabric or material may be drawn, so that an embroidery stitch may be
made upon any part thereof.
The apparatus I employ for feeding a thread or threads to the vertical bearded
needle usually employed consists of one or more thread spools placed to the right
of the needle under the bed of the machine, each spool being provided with a
spring pad or equivalent means to regulate the tension of the thread, each of which
is passed through two or more guide loops previous to being passed through the
thread-feeding cylinder, which has a worm cut on its lower end beneath the plat-
form. This cylinder is partly revolved by an horizontal worm which gears into it,
and has a sliding motion given to it by an excentric in the usual way; the feeding
thread is placed where required by the partial revolution of the horizontal worin
by means of bevel wheels moved by the hand of the operator. By such means I
am enabled to embroider any pattern of one or more colours upon the right side
of the fabric or material after being made up.

improvements applied thereto; Figure 2 is a plan of the under side of the same
machine; and Figures 3 are respectively a front, end view, and a side view of a
covering plate, hereafter referred to.
I employ a Bonnaz embroidering machine such as is described in the Speci-
fication of a Patent granted to William Edward Gedge, dated 11th July, 1873, and
numbered 2395, or a machine of similar construction, and cut away portion of the
platform or bed A of the machine upon each side of the needle disc in the direction
of the length of the machine, thereby forming a narrow bed, as shewn at B,
Figure 2, upon which a tubular fabric or material may be drawn, so that an
embroidery stitch may be made upon any part thereof; portion of the needle disc
is cut away until it is in a line with the right side of the narrow bed, as shewn at
Figure 2 by a dotted line. To prevent vibration of the narrow bed 1 secure by
screws or rivets on the lower side of a strengthening pieco E, E. The feeding
thread supplied to the vertical bearded or hooked needle usually employed is passed
through guide loops F previous to being passed through the feeding cylinder.
The spool-carrying bracket, heretofore placed adjacent to the feeding cylinder
under the bed of the machine, I either remove to the right of the guiding loops or
place the spool upon a pin secured to the floor under the machine in such a position
that the feeding thread will run clear of the hand of the operator and the
mechanism under the bed plate; the spool is provided with a spring pad or equi-
valent means to regulate the tension of the thread.
The feeding cylinder, which has a worm cut on its lower end beneath the bed,
and is partly revolved by an horizontal worm which gears into it, and has a sliding
motion given it by an excentric in the usual way, I place the horizontal worm in
such a position that it slides from the right to the left in its bearing bracket D), so
that it projects to the left less than heretofore. And to prevent the fabric or
material from injury by the worm while the embroidery is being made I form the
bearing bracket to the left as long as the projection of the screw, and bore out
such additional length somewhat larger than the diameter of the screw, as shewn

page_text: by dotted lines at C, Figure 1. The bracket to the right of the feeding cylinder I
cover with a plate D', shown separately at Figures 3; this plate is held in position
by one of the screws, which secures the bracket to the under side of the bed, and in
place of the thumb screw heretofore employed to secure the needle disc on the top
of the bed, which screw projected below the bracket, I use a screw D lying flush
with the under side of the bracket; the bearing bracket and the covering plate D'
being rounded at the ends there is nothing to obstruct the passage of the finished
hosiery or other tubular fabric or material round and along the narrow bed while it
is being embroidered.
"
The remaining parts of the machine are of the usual construction, and are
operated as heretofore.
Having now described the nature of my said Invention, and in what manner the
same may be performed, I declare that I claim the improved machinery and
apparatus, as above described, for embroidering finished hosiery or other tubular
fabrics or materials.
In witness whereof, I, the said James Yates, have hereunto set my hand
and seal, this Twenty-third day of May, in the year of our Lord One
thousand.eight hundred and seventy-seven.
Witness,
H. W. GOUGH, C. E.,
Nottingham.
