Improvements in Arrangements and Mechanism Acting upon and
Connected with the Shuttle Box Swells of Looms.
I JAMES LAMBERT of Carr Hall Mill, Haslingden, in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of the said invention, to be as follows :-
*
"
My invention is more particularly intended for weaving wide fabrics or sheetings
where a powerful "pick "is necessary to propel the shuttle through the "shed," and
its object is to relieve the shuttle from the pressure of the "swell" in the "shuttle
box "before the "pick" begins, and also to put pressure on the "swell" in the shuttle
box on the opposite side of the loom at the time the shuttle arrives at the end of the
"pick" to absorb its momentum and prevent rebound—and consequently by my inven-
tion a more effective "pick" is obtained and a less powerful "pick" is required and
there is thus less wear and tear.
My invention consists in a combination and arrangement of mechanism—namely―
On the ordinary shaft (or stop rod) under the "slay," which shaft has a finger or arm
at each end to act upon the back of the "swell" in each shuttle box, an arm or hook
is secured at one side of the loom, to which arm or hook one end of a helical
spring is attached the other end of which is connected to a cord, rope, chain
strap or other flexible attachment that passes under a pulley on a stud secured
in one of the arms carrying the "slay" and upon which it oscillates, the other
end of the flexible connection is then attached to the connecting rod, on that side of
the loom, between the crank for giving motion to the slay and the "slay."
The connecting rod oscillates up and down vertically, as well as to and fro with the
crank and when it is making its downward oscillation, the tension of the spring, and
thus the pressure on the "swells," is relieved, and is the least when the crank is at its
lowest position about which time the pick commences, and from the lowest to the
highest position of the crank or connecting rod the said spring is tightened and
pressure is thus put upon the "swells" to be ready to act to absorb the momentum
of the shuttle at the end of the pick and prevent rebound.
A lever is or may be used in place of the said pulley, and adjustable rods, between
the lever and crank connecting rod, and the lever and helical spring in place of the
flexible connections above referred to.

I JAMES LAMBERT of Carr Hall Mill, Haslingden, in the County of Lancaster,
Cotton Spinner, 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 :-
My invention is more particularly intended for weaving wide fabrics or "sheetings,"
where a powerful "pick" is necessary to propel the shuttle through the "shed," and
its object is to relieve the shuttle from the pressure of the "swell" in the shuttle box
before the pick begins, and also to put pressure on the "swell" in the shuttle box on
the opposite side of the loom at the time the shuttle arrives at the end of the "pick" to
absorb its momentum, and prevent rebound, and consequently by my invention a more
effective "pick" is obtained, and a less powerful "pick" is required, and there is thus
less wear and tear.
My invention consists in a combination and arrangement of mechanism, namely.
On the ordinary shaft (or stop rod) under the slay, which shaft has a finger or arm
at each end to act upon the back of the "swell" in each shuttle box, an arm or hook
is secured at one side of the loom to which arm or hook one one end of a helical
spring is attached, the other end of which is connected to a cord, rope, chain, strap
or other flexible attachment that passes under a pulley on a stud secured in one of the
arms carrying the “slay” and upon which it oscillates, the other end of the flexible
connection is then attached to the connecting rod on that side of the loom between
the crank for giving motion to the slay, and the slay.
The connecting rod oscillates up and down vertically as well as to and fro with the
crank and when it is making its downward oscillation the tension of the spring, and
thus the pressure on the "swells" is relieved, and is the least when the crank is at its
lowest position about which time the pick commences, and from the lowest to the
highest position of the crank or connecting rod, the said spring is tightened and
pressure is thus put upon the swells to be ready to act to absorb the momentum of the
shuttle at the end of the pick, and prevent rebound.
Fig. 1 is an elevation looking at the end of a loom slay, and will illustrate my
invention. a, framing, bone crank of the cranked shaft, c one of the connecting rods
between one crank and the slay board d, on one side of the loom, e the stop rod or
shaft, it has at each side of the loom a finger e¹ which comes against the framing or
a "frog" on the framing when the shuttle does not enter the shuttle box.
The shafte has also on each side of the loom, a finger e², that comes against the
back of each "swell" in the shuttle box on each side of the loom, all the parts above
referred to by letters of reference are ordinary and well known parts of Looms.
To a hook or other projection c¹ which is or may be adjustable in the lengthway of
the connecting rod c, on one side of the loom one end of a strap or other suitable

page_text: flexible connection fis attached, it then passes under a grooved pulley 9, which is
free on a stud secured in a slot in the side of the slay sword d, so that the stud may
be adjusted up and down as required.
The other end of the flexible connection it attached to one end of an helical or
other spring h, the other end of which is connected with an arm or hook projection e³
from the stop rod shaft e, this spring h thus acts to partly rotate the stop rod shaft e,
and bring the fingers e against the swells on the shuttle boxes.

The crank shaft rotates in the direction pointed by the curved arrow, and the
action will be as hereinbefore described.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is
The combination with the connecting rod (c) of Looms and with the stop rod or
shaft (e) of a flexible connection (f), pulley (g) and spring (h) as and for the purpose
herein before described and illustrated by the drawings.
