page_text: We, JOSEPH ANDREW, Manager, of No. 155 New Line Brittannia Bacup and
AMBROSE HOYLE TOMLINSON of 133 New Line Brittannia Bacup, Mechanic in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to improvements in Brakes used in connection with Looms,
which improved Brake is adapted to operate instantaneously and effectively upon
the surface of the Brake Wheel when a stoppage of the Loom is necessary, which
may be necessary in the event of the breakage of the weft thread, which is a chief
cause of stoppage or from other causes; as upon the occurrence of some disarrange-
ment of parts requiring immediate adjustment, or in case of accident to the operative.
Our invention is made of metal and its construction is as follows:-
Below or immediately under the Brake Wheel of the Loom we provide in a horizontal
position a Lever or Bar which is supported at any convenient part between its
extremities by means of a fixed stud, upon which the said Bar is free to turn or
oscillate, one extremity of the Bar is conveniently attached to the weft faller rod
of the Loom which rod is well understood, the other extremity of the Bar being
connected by means of a connecting link or lever to the one end of a circular shaped
metal piece which piece we term the "Brake," the said Brake being lined with leather
or other suitable material, the other end of the Brake being attached or conveniently
secured to a fixed stud.
On the Bar between the fixed stud or "fulcrum" and its extremity attached to the
Weft Faller Rod is provided a moveable weight, the weight may be adjusted on the
Bar in order to counterbalance the mechanism situate between the stud supporting
the Bar, and the stud supporting one extremity of the "Brake," or to maintain an
equilibrium of parts on each side of the stud supporting the bar.
The operation of our invention is as follows:-
:-
When the Weft Fork Motion comes into action the Weft Faller Rod becomes
disengaged, and allowed to fall, consequently the Bar falls with it, the other end of

page_text: the Bar with its attendant mechanism moves in an upward direction, the Brake
engaging with the circumferential surface of the Brake-Wheel at its lower part, thus
the motion of the Brake Wheel is effectively and instantaneously arrested. When the
motion of the Brake Wheel is to be arrested being necessary from causes other than
the breakage of the Weft Thread the Brake may be applied by sliding the weight
along the lever so as to cause the Brake to come in contact with the Brake Wheel.

We JOSEPH ANDREW Manager, of No. 155 New Line, Britannia, Bacup, and
AMBROSE HOYLE TOMLINSON Mechanic, of No. 133 New Line, Britannia, Bacup in
the County of Lancaster 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 and accompanying drawings:
Our Invention relates to the brakes used in looms for weaving and brought into use
on the breakage or cessation of supply of the weft as is well understood. Previously
to our Invention on the release of the brake lever a block upon the lever has been
brought suddenly into contact with the periphery of a rapidly revolving fly or brake
wheel upon the crank shaft but owing to the small surface in frictional contact with
such wheel the movements of the loom have not been arrested with suitable
promptitude. In lieu of the said brake block we employ a curved lined metal brake
strap or bar which is hinged by one end upon a stud or pin attached to the framing
or carried by a part so attached and is connected by its other end with the
brake lever.
the
In order that our Invention may be clearly understood we will describe the same
more fully with reference to the accompanying drawings wherein Fig. 1 represents
our improved brake apparatus in position upon a loom end, parts not necessary to
proper illustration of our Invention being left out in the drawing. In the said
Fig. a is the said fly or brake wheel; b is the said brake strap and c is the said brake
lever. The curved brake strap b is provided with a lining b₁ of leather or other
suitable material and is hinged at d upon a stud or pin. For convenience of application,
especially when applying our improved brake to replace the ordinary brake, we
sometimes employ an adjustable bracket to carry the stud d. Such a bracket is
represented in Fig. 3. The free end of the brake strap is connected by means of a
link e with the end of the shorter arm c¹ of the brake lever c. In the example the
connection of this link with the shorter arm of the lever is effected by means of a stud
which is adjustable in a slot in the end of the link. The brake lever is mounted upon
a fulcrum stud at fas is usual and is provided with a weight g. The end of the
longer arm of the lever is connected with the ordinary drop rod h which sustains
the loaded arm of the brake lever and thereby keeps the brake out of contact with the
wheel a during the ordinary working of the loom. On the release of this drop rod
the loaded arm of the lever drops as is usual and the brake strap is thereby raised so
that its lining is brought into frictional contact with the wheel a whereby the rotation
of the crank shaft is arrested. Owing to the large surface contact of the brake with
the periphery of the wheel the loom is brought to a stand more quickly as compared
with the result obtained with the ordinary brake. By adjusting the load in position
upon the lever the operation of the brake can be controlled so that when the lay comes
to rest it may be in its backward position this being an advantage as is well understood.
In Fig. 1 we have shown such a lever as we should make to suit the purpose of our

page_text: Invention, but when applying our Invention to replace the ordinary brake we
sometimes alter the ordinary lever in the manner indicated by Fig. 2. In this
example h is an ordinary brake lever and c¹ is an arm or extension piece which we
bolt on to the shorter arm of the lever in place of the brake block. The link e would
be connected with the outer end of the extension arm c¹.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
(1) The combination of parts forming the brake apparatus for a loom substantially
as set forth and indicated with reference to Figs. 1, 2 and 3 of the drawings.
(2) In apparatus for arresting the movements of a loom the curved lined brake
strap b arranged to act on the under side of the brake wheel and hinged at one end to
a fixed part and connected at the other end by means of a link with the shorter arm
of a brake lever c. c¹ in connection with the ordinary stop mechanism of the loom
substantially as set forth and indicated.
(3) The leather lined strap 6 hinged at d, the link e and the lever c. c¹ or the lever
represented by Fig. 2 provided with an adjustable load and connected with the stop
mechanism of a loom substantially as and for the purpose set forth and indicated.
(4) The extension piece c¹ bolted to the end of the ordinary brake lever of a loom
and connected by a link with the free end of a curved brake strap b which is hinged
by its other end upon a fixed stud at d substantially as and for the purpose set forth
and indicated.
