Lancaster, Gentleman, for an Invention of "IMPROVEMENTS IN LOOMS FOR
WEAVING"
PROVISIONAL SPECIFICATION left by the said James Kenyon at the Office
of the Commissioners of Patents on the 29th January 1881.

JAMES KENYON, of Blackburn, in the County of Lancaster, Gentleman.
"IMPROVEMENTS IN LOOMS FOR WEAVING."
The first part of my Invention consists in an improved form of strap fork. I
make the strap fork of an oblong or square section at the end that passes through
the spring handle or stop rod, and by preference twisted near the fulcrum. I pass
this end through the spring handle or stop rod, or I fit a small bracket on the spring
handle or stop rod, through which this end of the strap fork passes, thus forming
a bearing which keeps the strap fork from twisting, and ensures moro certain action
of the fork and greater durability.
The second part of my Invention consists in covering the foot of the picking
shaft (which works in a cast iron bearing) with cast iron, thus making the foot of
the picking shaft much more durable and effecting a great saving of oil.
The third part of my Invention consists in an improved shuttle box. I form
the guard of a bow spring each end of which is adjustable and secured by a bolt or
otherwise; in some cases I make the guard to swing on a stud at one end and use
a spring to press it inwards to hold the shuttle. I also apply a spring on the back
board instead of the wooden guide commonly used. I dispense with the slot in
the bottom of the shuttle box and guide the picker at the side.
The fourth of my Invention consists in the application of a double link to
the end of the weight rope, one link is long and forined wide below for the weight
lever to pass through, and at the upper end it is narrow, and over the upper end a
small link is placed; the rope is passed through the small link and the long link,
and the strain on the rope causes it to be held firmly, the long link being so formed
and curved that the small link cannot slip off when the rope is passed through
them but the rope is securely held between the side of the sinall link and tho end
of the long link.

"IMPROVEMENTS IN LOOMS FOR WEAVING."
The first part of my Invention consists in an improved form of strap fork. I
make the strap fork of an oblong or square section at the end that passes through
the spring handle or stop rod, and by preference twisted near the fulcrum. I pass
this end of the strap fork through the spring handle or stop rod, or I fit a sinall
bracket on the spring handle or stop rod, through which this end of the strap
fork passes, thus forming a bearing which keeps the strap fork from twisting and
ensures more certain action of the fork and greater durability.
The second part of my Invention consists in covering the foot of the picking
shaft (which works in a cast iron bearing) with cast iron, thus making the foot of
the picking shaft much more durable, and effecting a great saving of oil.
The third part of my Invention consists in an improved shuttle box. I form
the guard of a bow spring each end of which is adjustable and secured by a bolt or
otherwise; in some cases I make tho guard to swing on a stud at one end, and
use a spring to press it inwards to hold the shuttle. I also apply a spring on the
back board instead of the wooden guide commonly used. In some cases I dispense
with the slot in the bottom of the shuttle box and guide the picker at the side.
The fourth part of my Invention consists in the application of a double link to
the end of the weight rope, one link is long and formed wide below for the weight
lever to pass through, and at the upper end it is narrow, and over the upper end I
place a small link; the rope is passed through the small link and the long link,
and the strain on the rope causes it to be held firmly, the long link being so formed
and curved that the small link cannot slip off when the rope is passed through
then, but the rope is securely held between the side of the small link and the end
of the long link.
And in order that my Invention may be fully understood and readily carried
into operation I will describe the accompanying Sheet of Drawings, reference being
bad to the figures and letters marked thereon.
Fig. 1 is an elevation, and Fig. 2 is a plan showing a wrought iron strap fork
made according to my Invention.
a is the stop rod on which is fixed the bracket b in which is a rectangular slot,
through which passes the end of the strap fork c, on this strap fork is formed a
boss through which passes a pin fixed to the bracket & bolted to the loom frame e.
The oblong end of the strap fork may pass through the bracket in the stop rod,
vertically or horizontally, as shown at A and B.
Fig. 3 shows a strap fork made according to my Invention, partly of cast iron
and partly of wrought iron, held together by two bolts. Fig. 4 shows in section
an enlarged view of the fulcrum stud of the strap fork; this fork swivels on an
improved conical stud f which is bolted to a bracket fixed to the loom frame; the
cast portion of the strap fork is provided with a boss, in which is a taper hole to
fit the conical stud f, and at the bottom of the boss I form two segmental
projections which bear on the collar of the stud f; these projections y are to be
filed so as to allow the boss of the strap fork to descend when it wears loose on
the stud f.
Fig. 5 shows the foot of a picking shaft made according to my Invention, I
make the foot of the wrought iron shaft taper, and fit on it an annular shoe or
bush of cast iron, shown in section, in which is a taper hole; the shaft does not
extend quite to the bottom of the shoe, so that its taper form keeps it always
tight; the shoe works in an ordinary cast iron footstep.

page_text: Fig. 6 shows a plan, and Fig. 7 an elevation of my improved shuttle box; on
Fig. 8, x shows the spring which I use instead of the wooden guide, or instead of
the spring I use a casting marked r on Figs. 6 and 9 which acts as a picker and
check end regulator; o is the back board; p is the picker; q is the guide; is tho
small casting which rests loosely in an oblique slot in a brackets fixed to the
back board o; the inner part of rests against the picker; when it is at the end of
the return stroke the picker raises the casting, and the weight of 7 tends to retain
the picker and regulates the falling of the check end. Fig. 9 is an edge view
enlarged of the casting and bracket s. I make the slot at the bottom of the
shuttle box entirely through, and use an eye bolt to secure the end spring.
Fig. 10 is a front view, and Fig. 11 is an edge view of the two links for
connecting the weight rope and weight lever according to my Invention. The
weight lever is passed through the lower part of the large link t, and the rope is
passed through the small link and through the upper part of the link t, as shown,
and is thus securely held; the rope can be adjusted in a moment, and its tension
causes it to be firmly gripped by the links.
Having stated the nature of my Invention, and described the manner of
perforining the saine, I declare that I claim,-
1. Making the end of the strap fork that passes through the stop rod (or through
a bracket on the stop rod) of square or oblong section, as and for the purpose
shown and described.
2. Covering the foot of the picking shaft with a shoe or bush of cast iron, as
shown and described.
3. The improvements in shuttle boxes, described and shown on Figs. 6, 7, 8,
and 9.
4. The links shown on Figs. 10 and 11 for holding the weight rope.
In witness whereof, I, the said James Kenyon, have hereunto set my hand
and seal, this Twenty sixth day of July, One thousand eight hundred and
eighty one.
JAMES KENTON. (L.S.)
