PROVISIONAL SPECIFICATION.
Improvements in or Connected with Picker and Shuttle Checking
Appliances of Looms.
I, WILLIAM HENRY DUCKWORTH of 33 Baywood Street Blackburn in the County
of Lancaster, Pattern Maker do hereby declare the nature of this invention to be as
follows:-
This invention relates to improved appliances for dispensing with the check and
buffer straps and for economizing the pickers of looms.
According to this my invention I employ on the back of the shuttle box a metal.
slide piece having lugs or projections at its ends extending at right angles to the slide
piece and through which projections the picker spindle passes so that the slide piece
works along the picker rod but is also supported at its back by a slotted bracket and
bolt there being an indiarubber or other packing at opposite ends of the slots to break
the concussion or impact between slide, or slide bolt and said slot. A material part of
the invention consists in forming the projecting lug of the slide at the far or outer
end of the box of the same shape as the outline of the edge or end of the picker so
that when the latter comes in contact with the said lug and drives the slide and lug
along the picker spindle, the picker cannot tilt at all on the spindle thereby preventing
the wearing of the holes or eyes of the picker oblong.
The box tongue and the swell are carried by adjustable brackets so that when worn
can readily be set up or adjusted; the bolt carrying the bracket of the box tongue
also serves for holding and adjusting the spring of the tongue.

Improvements in or Connected with Picker and Shuttle Checking
Appliances of Looms.
1. WILLIAM HENRY DUCKWORTH of 33 Baywood Street, Blackburn in the County
of Lancaster, Pattern Maker, 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 :-
This invention relates to improved appliances for dispensing with the ordinary
check and buffer straps, and for economizing the pickers of looms.
According to this my said invention I dispense with the back board of the shuttle
box and fix to the back of the shuttle box by bracket, a strip or pad of wood on which
is a smooth piece of metal, or pad, behind this is a second metal pad held in position
against the former pad, by a blade spring; a leather strap passes between, and is gripped
by the two pads and is attached at one end by a loop of leather to the picker spindle
the other end of the strap carries a loop of leather which is passed over a short spindle.
These two loops of leather form the picker"check," and buffer, and are placed in
such a position that when the picker is driven along the spindle and comes in contact
with one or the other, the picker does not tilt, thereby preventing the wearing of the
holes, or eyes in the latter oblong.
.
The box tongue and swell are carried by adjustable brackets so that when worn
they can readily be reset or adjustod; the bolt carrying the bracket of the box tongue
also serves for holding and adjusting the spring of the tongue.
Such being the nature and object of this my said invention, the following is a
complete description of same, reference being had to the accompanying drawings :-
Fig. 1 is a front elevation of shuttle box with my improvements applied thereto.
Fio 2 is a plan view of fiv 1
-

page_text: Fig. 3 is a plan view of bracket or adjustable bearing for carrying the swell or
tongue and drawn to enlarged scale.
Fig. 4 is a plan view of tongne.
Fig. 5 is a plan view of metal pad and part of blade spring.
Fig. 6 is a side or back elevation of fig. 5.
According to this my said invention I dispense with the back board of the shuttle
box making the latter free and open and obviating all wear of the slide.
Fixed to the back of the shuttle box is a bracket 1 carrying a strip of wood 2 to
which is attached a smooth faced pad of metal 3 a second "faced" pad of metal 4
is held and pressed against the pad 3 by the blade spring 5 fixed by screws. to the
back of the shuttle box.
A leather strap 6 passes and is nipped between the two pads 3-4 and one end of
the strap 6 is attached to the picker spindle 7 by the loop of leather 8 which is passed
through a slot in the strap 6 and held by the peg 9. To the other end of the strap 6
I secure a loop of leather 10 which passes under the picker spindle 7 and over a short
spindle 11 fixed to the end of the shuttle box. The strap 6 is also attached to the
end of the shuttle box by a short strap 12. The picker 13 is mounted on the
spindle 7 in the usual way but the tongue or lower end works in a long groove 14
in the bottom of the shuttle box, and by holding the picker 13 in the manner
described I prevent all "tilting," and thereby wearing of the eyes or holes oblong.
It will be seen that at the forward or "out" pick of the loom, the picker 13
will come in contact with the loop of leather 8 and the momentum of the same
will be gradually eased as the strap 6 is allowed to slip between the two pads of
metal 3-4. When the shuttle enters the box its impact against the picker 13
will drive the latter against the loop 10 and the force of the shuttle and the
picker 13 will be gradually eased and stopped as described.
4
By holding the picker 13 in the manner above described the shuttle is thrown
or picked more steadily thus reducing liability to accidents from the flying out of
the shuttle. The box tongue 15 I form of malleable iron and the swell 16 of cast
iron and these are carried in adjustable brackets (see fig. 3) 17 and 18 so that
when the pins 19 or brackets 17 and 18 become worn they can readily be reset
and adjusted or tightened by simply unscrewing the nut 20 removing the part 22
of the brackets 17 or 18 and filing down the face 21. The nut 20 also serves to
regulate the pressure of the spring 20" on the box (see fig. 2). The box tongue 15
and grate 23 can be made in two parts (see fig. 4) so that if the grate 23 is broken
it can readily be renewed without replacing the entire box tongue 15.
The pad of metal 4 is secured to the blade spring 5 (see figs. 5 and 6) by set
screw, the screw 5 being received in the recess 5º cut in the pad 4.
Fig. 3. shews the swell 16 of an ordinary fast reed loom mounted in the brackets
or adjustable bearings constructed according to my said invention.
It is of course obvious that the above described invention is equally applicable
to fast as to loose reed loom.
Having now particularly described and ascertained the nature of this my said
Invention and in what manner the same is to be performed I declare that what
I claim is -
1. The general construction, arrangement and combination of parts constituting the
improved apparatus for purpose described and as illustrated by the drawings, (figs. 1 & 2)
and herein fully set forth.
2. The parts 17-22-19 and swell 16 in combination and constructed as and for
purpose herein fully described.
