PROVISIONAL SPECIFICATION.
Improvements in Driving, Brake, and Box Operating Mechanisms
of Looms for Weaving.
We, RICHARD LONGDEN HATTERSLEY of Keighley in the County of York, Machine
Maker, and JAMES HILL of the same place, Manager, do hereby declare the nature of
this invention to be as follows, that is to say :-
It relates to improvements in driving, brake and box operating mechanisms applicable
for looms for weaving and consists of constructing and arranging the parts forming
these said mechanisms in such a manner that certain desired results having their
several peculiarly novel advantages hereinafter described, are attained.
Respecting the driving mechanism we make use of a frictioning surface as a
pulley or an annular attachment to any of the wheels, mounted rigidly upon the
prime motor shaft of the loom. In proximity with this pulley or annular attachment
is a driving pulley (hereinafter styled primary pulley) loosely mounted upon the
said shaft. This primary pulley has it peripheral surface made to receive a driving
belt from which it receives its rotary motion, and upon the side of this primary pulley
is formed a frictioning surface to correspond and operate in connection with, so as
to impart motion to, the hereinbefore described friction pulley or annular attachment
to the wheel rigidly mounted upon the prime motor shaft.
In addition to the above described primary pulley we mount upon the same shaft
and in juxtaposition with the said driving pulley a supplementary driving pulley.
This supplementary pulley is of the same diameter as the above described primary
pulley, and it is made to revolve at all times loosely upon its shaft, being merely
employed to aid the primary pulley to carry the belt as hereinafter described.
Both the supplementary and primary pulleys may be and are moved laterally by
the starting and disengaging mechanism when the shaft upon which they are mounted
is desired to he put into or out of operation.
By the employment of the arrangement of parts as above described it will be
seen that while making use of a driving belt of sufficient width to transmit all or any
power necessary to maintain the loom in operation, only just sufficient frictioning
surface of said belt to thus maintain the loon in motion when in proper order need
be employed, this being regulated by an adjustable belt guide arrangement mounted
upon the frame work of the loom, the same being only so far moveable as is necessary
when required to be adjusted to regulate the quantity of frictioning surface or the
space that the belt has to extend from the supplementary pulley on to the primary
pulley, in this manner all the advantages of friction clutch driving mechanisin
together with those of the common fast and loose driving pulley mechanisms are
secured.
We preferably form the above described annular frictioning surface or clutch upon
the brake wheel of the loom, and the handle, employed for moving the primary and
supplementary pulleys laterally upon their shaft or for stopping or starting the loom,
is made to lay hold of, so as to operate a part well known as the "frog" which is
directly coupled to the brake acting in connection with this said brake wheel so that
whenever this "frog" is acted upon by the stop-rod of the loom in the common and
well known manner, the brake is instantly applied to the wheel and the driving
mechanism is simultaneously disengaged.
Relative to the box operating mechanism we make use of the well known arrange-
ment of continuously rotating partly toothed segments which are made to operate
partly toothed crank-wheels for the purpose of effecting changes in the positions of
the shuttle-boxes, however in accordance with our invention when we use these parts
as means for operating "drop-boxes" only having two compartments on each end

page_text: or side of the loom, instead of coupling their well known "box levers" by means of
chains to the box lifting rod we do so by means of levers and rods which are more
mechanical and do not so quickly deteriorate by wear and tear as do chains.
On that side of the loom where this box operating mechanism is mounted this
coupling or joining is effected by forming the box lever so that its projecting arm will
reach into line with the box and the centre of motion about which the slayboard
oscillates, this arm is then joined by a slotted rod to the box lifting rod by means of
the well known yielding spring arrangement which yields when the box lever is moved
provided anything is holding the box while the slot in the connecting rod allows the
box to fall by gravity.
Motion is imparted to the shuttle box on the other side of the loom by the use of
an intermediate lever mounted beneath the box lever and coupled thereto by a
connecting rod, this intermediate lever being also connected by a rod to a small lever
mounted in the upright supporting the box framework, this lever being coupled
to another similar lever on the other end of the loom, which is joined by suitable
rods etc. as above described to the shuttle box.
Our invention further relates to the employment of means for enabling the move-
ments of the above described box operating mechanism to be controlled by what is
known as an “open-shedding" dobby.
As is well known the time of movement of said open-shedding dobby, for the
purpose of operating the healds at the proper time for the passage of the shuttle, is at
variance with the time of movement necessary for selecting the changes in the
movements of the shuttle-boxes, however by the employment of our invention this
variance is entirely overcome.
We mount intermediary levers in such a manner that their outer ends, which are
coupled to the cranks or their gearing wheels lifting levers, shall always assume,
when not acted upon except by their several spring attachments, an elevated normal
position.
The outer ends of these levers are respectively coupled by means of slotted rods or
pliable cords to the levers in the open shedding dobby, and the cranks or their
gearing wheels lifting-levers.
By the employment of these slotted rods or pliable cords the space of time that the
movement of the dobby's levers precede those of the said lifting levers may be sufficiently
lost before the bottom of the slot is reached or the slack cord is tightened to move
said lifting levers, that the well known lever used for holding the above described
lifting levers in their raised and lowered positions, will have assumed its position for
thus holding said levers, so that all of said levers that have been selected, on the
withdrawal of this holding lever will assume their proper positions by those that are
required to be beneath it at its next movement, descending by gravity, while those
that are required to be above it are raised by the springs above described.

COMPLETE SPECIFICATION.
Improvements in Driving, Brake, and Box Operating Mechanisms
of Looms for Weaving.
We RICHARD LONGDEN HATTERSLEY of Keighley in the County of York Machine
Maker, and JAMES HILL of the same place Manager, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, that is to say :-
It relates to improvements in driving, brake and box operating mechanisms
applicable for looms for weaving and consists of constructing and arranging
the parts forming these said mechanisms in such a
manner that certain

page_text: desired results having their several peculiarly novel advantages hereinafter described,
are attained.
In the accompanying sheets of drawings Fig. 1 is end view of a portion of a loom
shewing the application of our improved driving and brake mechanisms, and Fig. 2
is a top view of same.
Figs. 3, 4 and 4" are end front and top views illustrating one portion of our
improved box operating mechanism while Figs. 5 and 6 are end and side elevations
illustrating the other part of our box operating mechanism as controlled or governed
by the dobby known as Hattersley's dobby.
Similar letters and figures of reference indicate similar parts throughout the several
views
In all the drawings only such parts of a loom are shewn, as are necessary to illustrate
the application of our invention.
Respecting the driving mechanism we make use of a frictioning surface as a separate
friction pulley of the kind well known, or an annular attachment a to any of the
wheels (such as the brake wheel c) mounted rigidly upon the prime motor shaft b. In
proximity with this (pulley or) annular attachment a is a driving pulley d (which
may be styled the primary pulley), loosely mounted upon the shaft b.
This pulley d
has its peripheral surface made to receive a driving belt from or through which it
receives its rotary motion, and upon the side of this pulley d is formed a frictioning
surface d' to correspond and operate in connection with so as to impart motion to the
hereinbefore described (friction pulley or) annular piece a and so to the shaft b.
In addition to the above described pulley d we mount upon the same shaft 6 and in
juxtaposition with the said driving pulley d, a supplementary driving pulley e. This
pulley e is of the same diameter as the pulley d, and it (said pulley e) is made to
revolve at all times loosely upon its shaft b, being merely employed to aid the primary
pulley d to carry the belt as hereinafter described.
Both the pulley e and the pulley d may be and are moved laterally by the starting
and disengaging mechanism when the shaft is desired to be put into or out of
operation. This disengaging mechanism consists of the lever f which lays hold of the
grooved hub f on the wheel d and is operated in one direction by the handle g through
the medium of the rods h and ¹ and the leyer k, and in the other direction by these
parts being drawn by the spring ³.
By the employment of the arrangement of parts as above described it will be seen
that while making use of a driving belt of sufficient width to transmit all or any
power necessary to maintain the loom in operation, only just sufficient frictioning
surface of said belt to thus maintain the loom in motion when in proper order need be
employed, this being regulated by an adjustable belt guide 1, mounted upon the frame-
work, the same being only so far moveable as is necessary when required to be
adjusted and fixed to regulate the quantity of frictioning surface or the space that the
belt has to extend from the pulley è on to the pulley d in this manner all the advantages
of friction clutch driving mechanism together with those of the common fast and loose
driving pulley mechanisms are secured.
e
We preferably form the above described annular frictioning surface or clutch a
upon the brake wheel c, as shewn by Fig. 2 although it might be mounted separately
on the shaft as shown by Fig. 2ª, and we also form the handle lever g to lay
hold of so as to operate the part m well known as the "frog," this part m being
directly coupled by the rod n to the brake o acting in connection with the said
brake wheel c, so that whenever the "frog m is acted upon by the stop-rod of
the loom in the common and well known manner the brake o is instantly applied
to the wheel c and the driving mechanism through the handle g, is simultaneously
disengaged.
,,
Relative to the box operating mechanism we make use of the well known
arrangement of continuously rotating partly toothed segments which are made to
operate partly toothed crank wheels for the purpose effecting changes in the positions
of the shuttle-boxes, however in accordance with our said invention when we use these

page_text: parts as means for operating "drop-boxes" that only have two compartments on
each end or side of the loom, instead of coupling their well known "box-levers" p p³,
by means of chains to the box-lifting-rods q q we do so by means of levers and rods
which are more mechanical and do not so quickly deteriorate by wear and tear as do
chains.
On that side of the loom where this box operating mechanism is mounted this
coupling or joining is effected by forming the box lever p so that its projecting arm p²
will reach into line with the box r and the centre of motions about which the slay
board or lay oscillates, this arm p² is then joined by a slotted rod t to the box-lifting
rod 9 by means or through the medium of the well known yielding spring arrange-
ment u which yields when the box lever p is moved to raise the box r (provided the
box is held by anything) while the slot in the rod t allows the box to fall by
gravity.
Motion is imparted to the shuttle box on the other side of the loom by the use
of an intermediate lever på mounted beneath the box-lever pl and coupled thereto by
a connecting rod t, this.intermediate lever p³ being also connected by a rod t² to a
small lever p¹ mounted in the upright u¹ which supports the box framework, this
lever p being coupled by the rod t to another similar lever p on the other end of
the loom and this lever p5 is coupled by the rod t the spring arrangement u² and the
box-lifting-rod q' to the shuttle box allowing this box similar freedom of action
to that allowed the box r as is hereinbefore described.
Our invention further relates to the employment of means for enabling the move-
ments of the above described box operating mechanism (that is operating mechanism
consisting of continuously revolving partly toothed segments, etc.) to be controlled by
what is known as an "open-shedding dobby."
As is well known the time of movement of said open-shedding dobby, for the
purpose of operating the healds at the proper time to make an opening in the warp
for the passage of the shuttle, is at variance with the time of movement necessary for
selecting the changes in the movements of the shuttle-boxes, however by the employ-
ment of our invention this variance is entirely overcome.
We mount intermediary levers v v¹ in such a manner that their outer ends 2, which
are coupled to the cranks or their gearing wheels lifting levers w shall always assume,
when not acted upon in any way except by their springs wo', an elevated normal
position.
The outer ends of these levers v are respectively coupled by means of slotted rods
and chains and a (or pliable cords) to the levers y in the open shedding dobby and
the cranks or their gearing wheels lifting levers w.
By the employment of these slotted rods and chains (or pliable cords) the space of
time that the movements of the dobby's levers precede those of the said lifting levers w
may be sufficiently lost before the bottom of the slots are reached or the slack chain
(or cord) is tightened to move said levers w that the well known lever z used for
holding the above described levers w, in their raised or lowered positions, will have
assumed its position for thus holding said levers w so that all of said levers w that
have been selected, on the withdrawal of this holding lever will assume their proper
positions by those of them that are required to be beneath it at its next movement,
descending by gravity, while those that are required to be above it (said lever 2) are
raised by their respective springs w' as above described.
Having now particularly described and ascertained the nature of our said inven.
tion and in what manner the same is to be performed we declare that what
we claim is.
1. The combination with a friction driving pulley of a supplementary loose or belt
carrying pulley and a fixed belt guide arranged to regulate or guide said belt so that
same may be made to extend the desired distance or space from the supplementary
pulley over or on to the friction driving pulley substantially as herein specified.
2. The pulley & having a frictioning surface d', the annular attachment a formed on

page_text: the wheel c or mounted separately on the shaft b as shewn by Fig. 2, and the belt
guide in combination, all said parts being formed and arranged to operate substantially
as herein described to attain the object set forth.
3. The combination of part a, the wheel c, the pulleys d and e, the lever f, means
for operating said lever and the brake mechanisin arranged to work in unison with
these parts substantially as specified and for the purpose described.

levers p³, p and p and the other parts herein described as constituting the remainder
of the box operating mechanism, in combination all these parts being formed and
arranged to operate substantially as herein set forth to attain the object specified.
5. The arrangement of slotted rods and chains or of pliable cords together with the
levers and springs herein described for enabling shuttle-box operating mechanism to
be controlled or governed by an open shedding dobby substantially as specified.
