applied to shuttles for preventing or greatly reducing the waste of yarn
when weaving from weft in the "cop."
In construction of loose reed looms I employ in lieu of the stop rod a
fixed rod, and mount thereon a series of bell-crank levers, the fixed rod
forming the fulcrum on which such levers work. The vertical arm of
cach lever is secured to the "back trash" for holding the reed in position
for the beat up. The other and horizontal arms of the said levers extend
under the slay beam, and are steadied or held in proper position by
means of a connecting rod and spring. On the advance of the slay to
make the beat up the ends of the horizontal arms of the bell-crank
levers will be firmly locked by a stop piece or stop pieces. Should the
shuttle fail to box, the reed will turn the bell-crank levers on their
ulcrum shaft, so releasing itself. Or a fixing having an elongated slot
hole therein may be attached to the slay sword, through which slot a
double catch piece is passed and suspended by means of a rod attached
to an arm connected to the reed cap, the upper part of the reed being
attached to the reed cap. When the reed advances to the beat up the
back of the catch or sneck of the double catch piece is passed under the
back part of the fixing attached to the slay sword, so locking the reed,
and when the slay is back the other portion or sneck of the double catch
picce engages with the front part of the fixing attached to the slay
sword. In the event of the shuttle being caught the slay cap
will move
on its centres, and the arm referred to as being connected with the reed
cap will lift the double catch piece through the slot hole in the fixing
attached to the slay sword, leaving the reed free to swing open.

I
For preventing the waste of weft when weaving from the "cop
affix (or place) near the head of the shuttle skewer a cup or concave
piece of metal or other suitable material, the cavity of which is equal to
the convex or round end of the cop, so that when the cop is forced on to
the skewer its base or end is not damaged or displaced, but is received
within the cup, the cop being run off without the waste heretofore
arising from its base or end being so damaged or displaced.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHRISTOPHER
CATLOW, of Burnley, in the County of Lancaster, Overlooker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of June, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Christopher Catlow, Her special licence
that I, the said Christopher Catlow, my exccutors, administrators,
and assigns, or such others as I, the said Christopher Catlow, my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thercafter 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 LOOMS FOR WEAVING," upon the condition (amongst others) that I, the
said Christopher Catlow, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and scals,
should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the
same to be filed in the Great Scal Patent Office on or before the Eighth
day of December 1874.
NOW KNOW YE, that I, the said Christopher Catlow, 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 (that is to say): :-
In constructing, loose reed looms I employ in lieu of the stop rod a fixed
rod, and mount thereon a series of bell-crank levers, the fixed rod forming
the fulcrum on which such levers work. The vertical arm of each lever is
received to the back trash for holding the reed in position for the beat up.
The other and horizontal arm of the said lever extends under the slay
beam, and are steadied or held in proper position by means of a con-
necting rod and spring. On the advance of the slay to make the beat

page_text: up
the end of the horizontal arm of bell-crank levers will pass on to
and be firmly held or locked by a stop picce. Should the shuttle fail to
lose the reed will turn the bell-crank levers on the fulcrum shaft, so
releasing itself.
cop
For preventing the waste of weft when weaving from the I affix
or place near the head of the shuttle skewer a cup or concave piece of
metal or other suitable materal, the cavity of which is equal to the
convex or round end of the cop, so that when the cop is forced on to
the skewer its base or end is not damaged or displaced, but is received
within the cup, the cop being run off without the waste heretofore
arising from its base or end being so damaged or displaced.
Such being the nature and object of this my said Invention I will
now proceed to describe the same in detail, and in order that the same
may be clearly understood I have hereunto annexed a Sheet of Drawings
illustrative thercof, and have marked the same with Figures of reference,
the same Figures referring to the same part in the different views.
In combining and arranging the parts of a loose reed loom according
to this Invention I employ in lieu of the ordinary stop rod a fixed rod 1
extending from end to end of the slay beam 2. On the rod 1 are three,
four, or more, according to the width of looms, cranked levers 3, the rod
1 being the fulcrum on which the levers 3 are free to move. The vertical
arm 4 of the levers 3 is secured to the back trash 5, which latter is thus
carried back by the levers 3 when required, as herein-after described.
The other arms 6 of the levers 3 extend, as shewn, partially under the
slay beam 2, and the said levers are steadied and held in position by
means of the connecting rod 7' and spiral spring 8. On the advance of
the slay to make the "beat up" the end 6 of the arms 3 will come in
contact with the rail 9 which extends across the loom,) so binding by
means of the arm 4 acting on the back trash 5 the reed 10 firmly in
position. Should however the shuttle be caught in the shed the pressure
on the face of the reed 10 would cause the reed to swing back on its
suspending point 11, and the lower end of the reed bearing against the
back trash 5 will turn the levers 3 on their fulcrums 1, thus raising the
ends 6 clear above the cross rail 9, and so avoid breakage.
Another arrangement is shewn at Fig. 2, varied only so far as to make
the cross rod 9 moveable. It is, as shewn, attached, by a bracket 12 to
cach of the slay swords 13, and oscilates therewith. As the slay moves

page_text: forward to make the beat up the small friction runner 14 descends the
incline 15, spiral spring 16 holding the runner down, the other end-or
cross rail 9 is thus raised and comes in. contact with the end 6 of the
lever 3, locking the reed securely. In like manner, should a shuttle be
caught in the shed, the lower end of the reed 10 tilts back and raises
the front part 6 of the levers 3 clear of the cross rail 9.
Having thus fully described the nature and particulars of this my
said Invention, I would have it distinctly understood that I lay no claim
to any of the parts considered separate from the combination and
arrangement of parts herein specially referred to and described in con-
nection with the loose reed.
In witness whereof, I, the said Christopher Catlow, have here-
unto set my hand and seal, this Twenty-eighth day of November,
in the year of our Lord One thousand eight hundred and seventy-
four.
