-PAROVISIONAL-SPECIFICATION.
Improved Brake Wheel, Shuttle Swell, and Slay Sword for
Looms.
JOHN HOLDEN 259 Rose Bank Blackburn Road, Haslingden, Lancashire
Weaver do hereby declare the nature of this invention to be as follows:-
The brake wheel is of the ordinary type, with the addition of an inner rim
or pulley A cast to the arms for the purpose of receiving the brake leather B,
by suitable levers the leather band B is drawn tight and so stops the loom
(Sheet 1).
The shuttle swell, I purpose to improve by the addition of a piece of india-
rubber A underneath the steel spring B this I contend will give more elasticity to
the same and tend to prevent splitting of the cops. (Sheet 2.)
The slay sword A is used for supporting the stop rod B, my improvement is in
providing an extension piece C, cast along with the main casting A, I claim that
this arrangement will give increased stability to, and prevent to a great extent
the vibration of the stop rod and so improve the quality of the cloth produced.

Improved brake wheel, Shuttle Swen, and play Sword Or
Looms.
JOHN HOLDEN 259 Rosebank, Blackburn Road, Haslingden, in the County of
Lancaster, Weaver, 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 :-
I will describe my improvements with reference to the drawings filed with my
Provisional Specification.
The improved brake wheel is shewn on Sheet No. 1 of the drawings and
consists of the addition of a second wheel or rim A cast to or otherwise attached
to, the arms of the ordinary brake wheel C. The object of this additional rim is
to obtain a larger braking surface. I propose to obtain this by means of a band
of metal or any other suitable material placed round the additional rim A one end
of which band B would be fixed to a pin or stud D in the loom side, the other end
being connected to the ordinary levers E used for applying the brake, by pulling
these levers E the band B is brought to bear tightly on the rim A and the loom
immediately stopped, the largely increased surface or area by attaching rim A
giving the operator no trouble in quickly stopping the loom without jerking as if
often the case in the existing cases.
The improved shuttle swell, illustrated on Sheet No. 2 of the drawings consists
of the application of a device to prevent breakage of the cops caused by the sudden

page_text: check of the shuttle at the end of each stroke; the means I employ may be
described as follows:-
The
Attached to one end of a loom is a piece of wood known as a box side C, one
end D of which is near the reed. On this box side is fixed the shuttle swell.
swell now in use is a curved piece of steel or iron each end being bolted through
the box side. The shuttle in its passage from end comes in contact with a picker
at each end, and the object of a swell is to prevent the shuttle flying out or from
tilting upwards or downwards that is to keep it in a horizontal position, it is
therefore desirable to ensure the shuttle passing over as large an area of swell as
possible. Heretofore with the swell being curved the shuttle in its passage only
touches the crown of the swell. I propose to attach to the box side a piece of thin
steel or other suitable material B fastened at one end by screws or rivets E: In the
box side under this steel swell is cut a slot in which is placed indiarubber, felt or
other pliable material to act as a cushion A. By these means the swell being flat
and elongated the shuttle in its passage touches a much longer surface than can be
possible in a curved or low shaped swell and therefore reduces the liability of
flying or tilting shuttles with its attendant danger of breaking cops.
My improvements in slay sword are shewn on Sheet 3. A shews the slay sword
as now used, B the stop rod D a bracket on slay sword which is the means at
present employed of supporting rod D. In the working of the stop rod-which is
for keeping the reeds tight-there is often great vibration due to the long distance
between the supports. In order to reduce this vibration I propose to cast or
otherwise affix to the slay sword A a piece of metal or bracket C of the shape
shewn on drawing through which the stop rod B would pass, the addition of this
bracket reduces the span and gives a larger bearing surface.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. For the additional rim or wheel on the brake wheel and the method of
obtaining breaking surface.
2. For the steel or other metal spring shuttle swell with cushion.
2 For the additional hranket on hannar for stan rod
