IMPROVEMENTS IN SCREW GILLS OR HACKLE FRAMES
Year: 1865

page_text: LETTERS PATENT to Thompson Beanland, of Leeds, in the County of
York, for the Invention of "IMPROVEMENTS IN SCREW GILLS OR HACKLE
FRAMES."
Sealed the 17th November 1865, and dated the 24th May 1865.
PROVISIONAL SPECIFICATION left by the said Thompson Beanland at
the Office of the Commissioners of Patents, with his Petition, on the
24th May 1865.
I, THOMPSON BEANLAND, of Leeds, in the County of York, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN SCREW GILLS OR
HACKLE FRAMES," to be as follows:-
My Invention has for its objects the prevention of breakages in screw gills
or hackle frames, and consequently in the slivers of material under operation.
It is well known that the hackles or gills frequently acquire "laps," that is,
that material which should pass through them becomes wrapped round them;
also that derangements of the machines arise from various causes, and
therefore cause breakages of the same, and of the material under operation.

page_text: To obviate these defects on what is known as the draft or back wheel shaft of
an ordinary hackle or gill frame I place a saw-toothed clutch. On the same
shaft I place another clutch inside of the previous one, capable of sliding
upon the shaft, and working in conjunction with the same.
The shortest
arm of a double bell-cranked lever (working on a fulcrum attached to the
Tramework of the machine) presses against the outer clutch. The arm
parallel with the short arm rests in a notch of a bar connected with the strap
or belt guide, and which when the machine is in proper working order retains
the same on the driving pulley, whilst the intermediate arm of the lever
carries a weight, which may be adjusted according to the number of "heads "
the machine has. Lapping or other disturbing causes arising, however, the
clutches become disengaged, and the outer one pressing against the shorter
arm of the double bell-cranked lever elevates the end of the longer arm, and
releases the detaining bar connected to it from the lever connected to the
strap guide. A weight passes over á pulley, and connected to this lever
imparts a horizontal motion, and in so doing throws the belt by means of the
strap guide connected to it from the fast to the loose pulley, and thus prevents
the breakage that would otherwise occur.
.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thompson Beanland in the Great Seal Patent Office on the
23rd November 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMPSON
BEANLAND, of Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of May, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Thompson Beanland, Her special licence that I, the said Thompson Beanland,
fiiy executors, administrators, and assigns, or such others as I, the said
Thompson Beanland, my executors, 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
inuke, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven

dition (amongst others) that I, the said Thompson Beauland, 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 Thompson Beanland, do hereby declare.
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
My Invention has for its objects the prevention of breakages in screw gills
or hackle frames, and consequently in the slivers of material under operation.
It is well known that the hackles or gills, and the back or retaining rollers,
frequently acquire "laps," that is, that material which should pass through
them becomes wrapped round them; also that derangements of the machines
arise from various causes, and therefore cause breakages of the same, and of
the material under operation. To obviate these defects on what is known as
the draft or back wheel shaft of an ordinary hackle or gill frame, to the
clutches generally used I place the shortest arm, of a double bell-cranked
lever (working on a fulcrum attached to the framework of the machine),
which presses against the spring in the outer clutch. The arm parallel with
the longer arm rests in a notch of a bar in adjunction with the strap or belt
guide, and which when the machine is in proper working order retains the same
on the driving pulley, whilst the horizontal arm carries a weight, which may
be adjusted according to the number of "heads "the machine bas. Lapping
or other disturbing causes arising, however, the clutches become disengaged,
and the outer one pressing against the shorter arm of the bell-cranked lever
elevates the end of the longer arm, and releases the detaining bar connected
to it. A weight passes over pulley, and connected to this detaining bar
imparts a horizontal motion, and in so doing throws the belt by means of tho
strap guide in adjunction with it from the fast to the loose pulley, and thus
prevents the breakage that would otherwise occur..
But in order that my Invention may be the better understood, reference is
made to the accompanying Sheet of Drawings, and to the letters and figures
marked thereon, similar letters representing similar parts, that is to say;→

page_text: Figure 1 is a back elevation of a portion of a gill frame shewing my
improved apparatus attached, whilst Figure 2 represents a partial end
elevation with apparatus attached. It being intended only to apply my
improvements to gill or hackle frames, the letters marked on my Drawings
refer only to my improvements, and to such portion of the gill or hackle
frames as may be essential to describe the same.
Letters A represent the ordinary fast and loose pulleys having belt guide
B to pass belt C from one to the other. The guide B is keyed on to shaft 6,
and rests in brackets c, the latter being secured to the frame end of the.
gill or hackle frame D in the usual manner, the shaft b being also retained in
proper position by usual collars b. The inner end of the shaft is placed
within a short distance of the foot c¹ of the shaft E, which rests in brackets
el, e, secured to framework D of the gill or hackle frame. To the bracket e¹¹
a stud fis attached on the boss, by preference, to which stud I connect a chain
or rope f, passing over a pulley f" to weight f. Upon the shaft E I cut
a notch to receive one end or toe of my bell-cranked lever, the upper or
vertical arm of the said lever having a boss sliding upon the shaft G. This
latter shaft. G has upon it, free to slide horizontally, a steel washer
9, a helical
spring g', a clutch boss g", also a fast clutch g, actuated by the worm
shaft of the gill or hackle frame. The horizontal lever on the bell-cranked
shaft F may have a graduated scale of notches capable of retaining the
weight, the distance of which from the fulcrum a¹ is regulated according to
the number of heads used.
The action of the apparatus is as follows:-Some retarding cause, as
"lapping," coming into force, the shaft F through which, by means of the
bevilled wheels h, the shaft G is operated upon either entirely or partially
ceases to revolve. The motive power through the driving pulley A being
supplied as usual, the loose clutch 9" is thrown out of gear with the fast
clutch g, and compresses the spring g', which latter in turn through the
washer throws the vertical or upper arm of the lever F on its fulcrum a¹.
This action lifts the toe of the said lever out of the notch in the shaft E. (as
also weight on shaft F), and thus by the action of the weight f" upon the
chain f¹ the foot e¹ is brought to bear upon the shaft b of the strap guide B,
and throws off the belt until the disturbing cause is removed. The machine
is set in motion in the ordinary manner.
I

page_text: Having now described the nature of my Invention, and in what manner
the same may be performed, I would have it understood that what I claim as
novel is, simply the combination of parts shown and described, for the
purpose of throwing off the belts of gill or hackle frames, thus preventing
breakages.
In witness whereof, I, the said Thompson Beanland, have hereunto set
my hand and seal, this Twenty-second day of November, in the year
of our Lord One thousand eight hundred and sixty-five.
