Year: 1870

page_text: LETTERS PATENT to Hugh McEntee Ward, of Loop Bridge Mills,
Ballymaconaghy, County of Down, Ireland, for the Invention of
"IMPROVEMENTS IN MACHINERY FOR SPINNING AND TWISTING FIBROUS SUB-
STANCES.
"
Sealed the 15th September 1870, and dated the 6th July 1870.
PROVISIONAL SPECIFICATION left by the said Hugh McEntee Ward
at the Office of the Commissioners of Patents, with his Petition, on
the 6th July 1870.
I, HUGH MENTEE WARD, of Loop Bridge Mills, Ballymaconaghy,
County of Down, Ireland, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING AND TWISTING
FIBROUS SUBSTANCES," to be as follows:-
The object of this Invention is to stop the supply of sliver or material
to be twisted or spun to the top or feed rollers when the sliver or thread
breaks. To this end I provide for each pair of feed rollers an arrange-
ment of mechanism, which on the breaking of the sliver will be set in
action and will push the sliver out of the bite of the rollers, and will
hold the broken end securely until the sliver is joined, and the
mechanism is restored to its normal position. In rear of the bar which
guides the rovings or slivers to the bite of the top or feed rollers, I

page_text: mount a fixed bar parallel thereto for the purpose of carrying a series of
forks, one for each pair of feed rollers; these forks are intended to guide
the slivers, and they are pivotted to the fixed bar so as to lie horizontally
over the rollers and be free to rock to and fro. The forks are severally
provided with a curved rear extension or tail piece, which is embraced
by a lever pivotted to and pendent from a bracket attached to the back
of the fixed bar. The upper end of each of these pendent levers ter-
minates in a curved finger which bears upon the tail end of a rock lever
pivotted to a bracket attached to the front of the fixed bar; this rock
lever carries a loose weight which is slotted transversely to allow it to
ride on the guide bar before mentioned, and it is formed with an eyc
through which the sliver passes to the feed rollers, a lateral extension
being made to this eye to facilitate the insertion of the sliver. To the
lower end of each pendent lever is attached an arm carrying a pin or
roller at its outer end over which the thread or sliver passes on its way
to the flyer. The pressure which the thread puts on this pin or roller
serves to hold back the lower end of the pendent lever and keep its
curved finger bearing upon the tail end of the rock lever carrying the
weight through which the sliver passes. In rear of the arm carrying
the pin is a catch carried by the pendent lever. This catch is intended
(when the breaking of a thread causes the lever to fall forward) to
present itself to the ordinary rocking bar, and thus enable that bar to
give a forward impetus to the pendent lever, whereby it is caused to
throw the fork connected with it to one side and thus move the sliver
out of the bite of the feed rollers. At the same time this motion of the
pendent lever allows the weighted lever to rock and drop the weight
upon the guide bar. The effect of this movement will be to hold the
sliver firmly between the weight and the guide bar, and to stop a
further supply until the sliver is pierced and the mechanism is re-
adjusted.
P
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Hugh McEntee Ward in the Great Seal Patent
Office on the 6th January 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HUGH
MENTEE WARD, of Loop Bridge Mills, Ballymaconaghy, County of 3
Down, Ireland, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of July, in the year of our
Lord One thousand eight hundred and seventy, in the thirty-fourth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Hugh McEntee Ward, Her special licence that I, the
said Hugh M'Entee Ward, my executors, administrators, and assigns, or
such others as I, the said Hugh McEntee Ward, my executors, adminis-
trators, 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 Ircland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY
FOR SPINNING AND TWISTING FIBROUS SUBSTANCES," upon the condition
(amongst others) that I, the said Hugh McEntee Ward, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, 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 Hugh McEntee Ward, do hereby
declare the nature of my said Invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the Drawing hereunto
annexed, and to the letters and figures marked thereon (that is to
say) :-
This Invention relates to an improvement in the arrangement of
machinery for which I obtained Letters Patent, dated May Ninth Onc
thousand eight hundred and seventy, No. 1325, the object of which
was to stop the supply to the top or feed rollers of sliver or material
to be twisted or spun when the sliver or thread breaks. To attain the
same end I now provide for each pair of feed rollers an arrangement
of mechanism which on the breaking of the sliver or thread will be
set in action, and will push the sliver out of the bite of the rollers,
the broken end being at the same time held securely as before until the
sliver is joined and the mechanism is restored to its normal position.
In the accompanying Drawing I have shown in plan view at Fig.1,

page_text: and in sectional elevation at Fig. 2 my improvements. In these
Figures A, A', are the top or feed rollers; and B, B³, are the drawing
or delivery rollers; C is the bar which guides the rovings or slivers to
the bite of the top or feed rollers; D is the pendent lever (one for each
pair of top rollers) which is held in position by the twisted sliver or
thread that is being spun. In rear of the guide bar C I mount a fixed
bar E parallel thereto for the purpose of carrying a series of forks F,
one for each pair of feed rollers. Between the prongs of these forks
the slivers pass to the feed rollers, and the space between the prongs is
such as to allow of the slivers being traversed as usual over the rollers
to distribute the wear over their surfaces; these forks are pivotted to
the fixed bar so as to lie horizontally over the rollers and be free to
rock to and fro. The forks are severally provided with a curved rear
extension or tail piece F", which is connected to or embraced by an
extension of the pendent lever D; this lever D is pivotted to and
pendent from a bracket attached to the back of the fixed bar E. The
upper end of each of these pendent levers terminates in a curved finger
D', which bears upon the tail end of a cranked rock lever G pivotted
to one of a series of brackets attached to the front of the fixed
bar E; this rock lever G carries at its upper end a weighted presser
piece H, which is made to drop into a groove formed in the guide bar C
before-mentioned, and under it (when the presser piece is raised) the
sliver passes to the feed rollers. To the lower end of each pendent
lever is attached an arm D2 carrying a pin or roller d at its outer end,
over which the thread or sliver passes on its way to the flyer. The
pressure which the thread puts on this pin or roller serves to hold back
the lower end of the pendent lever in the position shown by the drawn
lines of Fig. 2, and keep its curved finger bearing upon the tail end of
the rock lever G, carrying the weight under which the sliver passes.
The arm D² extends rearward and forms a stop D³, which is intended
(when the breaking of a thread causes the lever to fall forward towards
the dotted position of Fig. 2) to present itself to the ordinary rocking
bar I, and thus enable that bar to give a forward impetus to the pendent
lever, whereby that lever will be caused to throw the fork F connected
with it to one side or into the dotted position of Fig. 1, and thus move
the sliver out of the bite of the feed rollers. At the same time this
motion of the pendent lever allows the rock lever G to drop the
weighted presser piece H into the groove of the guide bar C. The

page_text: effect of this movement will be to hold the sliver firmly between the
weight and the guide bar, and to stop a further supply until the sliver is
pierced and the mechanism is readjusted.
In order the more effectually to stop the supply of sliver when the
thread is broken, I mount on the extremity D¹ of the lever D the
tumbling catch D', which as the lever is thrown into the dotted position
of Fig. 2 will catch on to the fixed bar E, and retain the lever in the
dotted position, at which time it will be clear of the weighted lever G.
In order to readjust the mechanism for the recommencement of the
spinning operation, the attendant first lifts the tumbling catch D
off the bar E, and then pushes back the arm D³ which causes the
pendent lever D to pull the fork F (between the prongs of which the
sliver hangs) into the position shewn by the drawn lines of Fig. 1,
and the curved finger of the pendent lever D at the same time raises
the weighted lever G. The attendant then draws down the rove into
the bite of the rollers, and pieces the thread, after which the operation
of spinning goes on as before.
Having now set forth the nature of my Invention of " Improvements
in Machinery for Spinning and Twisting Fibrous Substances," and
explained the manner of carrying the same into effect, I wish it to be
understood that I claim, the application of the forks F and the means
above described for actuating the same for the purpose of throwing a
broken thread or sliver out of the bite of the feed rollers.
.
In witness whereof, I, the said Hugh McEntee Ward, have here-
set my hand and seal, the Thirtieth day of December in the
year of our Lord One thousand eight hundred and seventy.
