IMPROVEMENTS IN SPINNING MACHINERY
Year: 1866

page_text: LETTERS PATENT to William Sunderland, of Windhill, near Shipley, in
the County of York, and George Stell, of Shipley, also in the County of
York, for the Invention of "IMPROVEMENTS IN SPINNING MACHINERY."
Sealed the 24th October 1866, and dated the 28th-April 1866.
PROVISIONAL SPECIFICATION' left by the said 'William Sunderland and
George Stell'at the Office of the Commissioners of Patents, with their
Petition, on the 28th April 1866.
We, WILLIAM SUNDERLAND, of Windhills near Shipley, in the County of York,
and GEORGE STELL, of Shipley, also in the County of York, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN SPINNING MACHINERY,"
to be as follows:-
*Our. Invention has for its objects the prevention of snarls, hard waste, and
double in the process. of. spinning yarns; at the same time being.so arranged
as to enable the "minder" to "piece"..easily, and to have free access to the
necks. 'and arbors or shafts of the bottom rollers. For this purpose instead.
of affixing, as is usually done, pieces of tin or other metals underneath the
"top boards" through which the thread is guided by means of "eyes,"

page_text: usually made of earthenware, at intervals equidistant from each other and
on either side of each spindle, we place in similar positions relatively to the
spindles, but independent of the top board, pieces of metal, brass, (by
preference) or other suitable material, extending to a sufficient distance
both above and below the "top board" to prevent the thread from one pair
of delivering rollers joining that of the next, as before named. These pre-
ventive or division pieces are connected to arms having bosses and counter-
balance weights, the bosses being secured by means of set screws to a shaft
free to rotate in brackets secured to the "back boards" to which the hinges of
the "top board" are secured, the "top boards" themselves having a strip of
metal running along the back with a crank formation opposite to each preven-
tive or division piece for the free lifting of the former. The "minder is thus
enabled by means of the balance weights before named, which keep the division
pieres in their proper position, to depress the same for the purposes of "piecing"
or of taking laps off.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Sunderland and George Stell in the Great Seal
Patent Office on the 26th October 1866. .
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
SUNDERLAND, of Windhill, near Shipley, in the County of York, and GEORGE
STELL, of Shipley, also in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria,..by Her Letters
Patent, bearing date the Twenty-eighth day of April, in the year of our. Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said William Sunderland and George Stell, Her special licence that we, the.
said William Sunderland and George-Stell, our executors, 'administrators, and
assigns, or such others as we, the said William Sunderland and.. George.
Stell, our exécutors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise, .
and vend, within the United Kingdom of Great Britain and Ireland, the:
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
SPINNING MACHINERY," upon the condition (amongst others) that we, the said

page_text: William Sunderland and George Stell, our executors or administrators, by an
instrument in writing under our or their hands and seals, or under the hand
and seal of one of us or them, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date, of the said 'Letters
Patent.

:
NOW KNOW YE, that I, the said William Sunderland, on behalf of myself
and the said George Stell, do hereby declare the nature of the said Invention,:
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, that is to say:—
Our Invention has for its objects the prevention of snarls, partially hard
waste, and double in the process of spinning yarns, at the same time being so
arranged as to enable the "minder" to "piece "easily, and to have free
access to the necks and arbors or shafts of the bottom rollers. For this
purpose, instead of affixing, as is usually done, pieces of tin or other metals
underneath the top boards (through which the thread is guided by means:
of "eyes," usually made of earthenware) at intervals equidistant from each:
other and. on either side of each spindle, we' place in similar positions.
relatively. to each of the spindles, but independent of the "top board,".
pieces of metal (brass by preference), or other suitable material, extending.
to a sufficient distance both above and below the "top board" to prevent
the thread from one' pair of delivering rollers joining that of the next, as.
before named. These preventive or division pieces are connected to arms.
having bosses forming counterbalance weights, the bosses being secured by.
means of set screws. to a shaft, and working by centres or pivots, in brackets
secured to the back board to which the hinges of the "top board" are
secured, the "top board" itself having a strip of metal running along the
back with a crank formation opposite to each preventive or division piece for
the free lifting of the former. The "minder" is thus enabled by means of..
the counterbalance weights before named, which (by the aid of a regulating
catch under the back board), keep the division pieces up to their proper
position, to depress the same for the purposes of "piecing" or of taking laps.
off. The same object.may be attained by the use of a straight instead of a
cranked plate, and. we prefer this arrangement on the ground of economy, the
other parts. remaining the same.
But in order that our Invention may be the better understood reference is..
made to the accompanying Sheet of Drawings, and to the letters and figures.

DESCRIPTION OF DRAWINGS....
i "
Figure 1 represents our second and preferred arrangement, showing, a plan
of the back: board, top board, and partition or division pieces, in position;
Figure 2 shows the same in section, together with the relative position of the
top and bottom rollers to the " top board," as also, the position of the spindle
and flyer; Figure 8 shows a plan of our first-named or cranked arrangement.
having cranks or inlets in the bar which carries the "top board"; Figure 4.
represents a side elevation of a full-sized partition or division plate connected:
with its counterbalance weight; whilst Figure 5. is simply. a repetition, of
portions of Figure. 2:
Referring to Figures 1 and 2, A shows the "top, board secured to the
bar B, which latter works on hinges let into the back board; C, D, is: a
bracket secured underneath the back board C, and carries the shaft E (by
means of pivots ), upon which the balance weights F are cast or otherwise
secured; these balance weights are soldered or fastened in any other con-
venient manner by lips f to the partition or division plate G. X, X², Figure 2,
show the ordinary top and bottom rollers arranged as is customary in throstle
spinning machinery, to which our Invention has special reference. The
plate G, Figure 2, is in working position, being there kept (when not depressed.
by the "minder") by the regulator catch H, the latter being adjustable by.
means of a slot in the bracket h; in this position it is evident from the shape.
of the plate G, which projects above and below the top board A, an effectual
separation is made between any two contiguous spindles or pairs of top and
bottom rollers; on the other hand, if the "minder" wishes to get. laps or.
waste off the necks or arbors of the bottom rollers'no difficulty is presented, as
he simply has to depress the plate G by a slight pressure on the upper part,
such plate swinging, together with those on its. shaft, on the axes e, it..and
they being restored to position on the pressure, being taken away by the.
counterbalance weights F, the regulator: H preventing, the shaft E from
going too far.
Having now fully described and ascertained the nature of our Invention,
and in what manner the same may be performed; we would have it understood
that we do not confine ourselves to the precise details shown, as the same may
of course be modified, but what we do claim as and of our Invention' is.a
self-acting swinging partition plate, free to move in a slot in the "top board,”.

page_text: of the nature shewn and described, in conjunction with either a cranked "top
board" plate as shown in Figure 3, or a straight one as shown in Figure 1.
In witness whereof, I, the said William Sunderland, have hereunto set
my hand and seal, this Twenty-fifth day of October, in the year of our
Lord One thousand eight hundred and sixty-six.
