IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1884

page_text: I CHARLES SMITH of 8 Bridge Terrace, Carlisle in the County of Cumberland,
Mechanic, do hereby declare the nature of my said invention for IMPROVEMENTS
IN LOOMS FOR WEAVING, to be as follows:-
My invention is designed to relieve the shuttle, (in fast reed looms) from the
pressure of the swell, on entering and leaving the box. I fix to the tab or tongue
of the stop rod a stud, on which is placed a small pulley, in such a manner that
with the backward movement of the sley, the pulley is raised by coming in contact
with a projection upon which it rests, whilst the shuttle is delivered, and received,
in the opposite box. The projection is adjustable so that it may be raised or
lowered as required. A set screw is provided in the projection to regulate, and
limit, the position of the frog. A light spring may be used to press gently against
each swell, to prevent the rebound, of the shuttle, when relieved, from the pressure,
of the stop rod fingers, previously bearing against the swells.
A modification of my invention, consists in dispensing with the frog and in lieu
thereof, I use a vertical lever having two arms. The tab or tongue of the stop
rod is similarly actuated as above described. The upper arm, of the lever, is placed
in suitable position to be acted upon by the tab or tongue of the stop rod, should
the shuttle fail to raise the tab in passing the upper arm of the lever; at which
time the said arm strikes the spring handle out of its detent, shifting the strap
from the fast to the loose pulley; during this operation the lower arm of the lever,
acting upon another lever which is in communication with the back rest, releases
the warp so that when the shuttle is caught therein the sley may be moved forward
without damage to the warp threads.

page_text: I CHARLES SMITH of Trafalgar Street Foundry, Burnley, in the County of
Lancaster late of 8 Bridge Terrace, Carlisle, in the County of Cumberland,
Mechanic, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN LOOMS FOR WEAVING " and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement aided by
the annexed drawings:-
My invention is designed, to relieve the shuttle, (in fast reed looms) from the
pressure of the swell, on entering and leaving the box, and for operating the back
rest, and thereby to release the warp, when the shuttle is caught, or trapped therein,
so that the slay may move forward, without damage to the threads.
warp
Such being the nature, and object of my invention, the following is a complete
description of same, reference being had, to the accompanying drawings, forming &
part of this specification in which :-
Fig. 1 is a cross section of part of a loom shewing the improved apparatus, for
releasing the shuttle, from pressure of the frog.
Fig. 2 is a front elevation of Fig. 1.
Fig. 3 is a side elevation of loom, shewing the improved apparatus, for stopping
the loom, and releasing or slackening the warp, when the shuttle is caught or
trapped in the shed.
At 1 is the shuttle-2 the swell. 3 the finger, connected with the lever, and stop
rod 4, as ordinary-At 5 is the tab, to which is bolted the bracket 6, carrying on
stud 7. the runner, or anti friction pulley 8, which at each backward movement of
the slay, mounts and runs upon the radial projection 9, thereby raising the
parts 5. 4. 3. and taking the pressure off the swell, 2, but at each forward move-
ment of the slay, the runner or anti friction pulley 8. will run off, or over the
end 10, of the projection 9, so as to permit the end of the tab, to descend, and be
in position to reach the frog 11, should the shuttle fail to box-12 is the ordinary
spring for bearing down the tab.
Referring now to Fig 3-At 13 is a lever, having two arms 14. 15, and fulcrum
at 16, the upper arm 14 has a notch 17, and forms a swivelling frog, the lower
arm 15, by means of a pin 18-received in the curved slot 19, holds the brake
lever 20, in position of rest, during the ordinary working of the loom-Should
the shuttle be trapped, or caught in the shed, the tab 5, of the stop rod, will reach
the sneck 17, and cause the lower end of the lever 13, to move, and withdraw the
pin 18, out of the curved end of the slot 19, whereon the weight of the warp, and
healds 21, upon the back rest 22, forces down the lever 23, and by connecting
rod 24, bears upon the end 25, of the lever 20, the brake 26 being thus applied to
the brake wheel 27. The forward radial movement of the back rest 22, gives off
the yarn, so that there is a sufficient quantity of slack yarn, in front of the reed,
to contain the shuttle without breaking the ends, or warp threads Meanwhile the
action of the tab. 15, upon the sneck 17, moving backwards the part 14, of the
lever 13, causes the stud 28, to come in contact with the part 29, projecting from
and attached to the stop handle 30, which is knocked off simultaneously, with the
release of the warp, and application of the brake, as above described.
The improvements herein described, for convenience of description, and clear
illustration, are shewn on separate looms-but the whole improvements may be used
in combination, on one loom, or separately, as illustrated by the drawings.

page_text: 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 :-
1. The bracket 6, pulley 8, and radial projection 9, in combination with the tab,
stop rod, and stop rod finger, for purpose herein fully described.
2. The double lever 13, operated by the tab 5, operating pin and stud 18-28,
for releasing the brake lever 20, and stop handle 30-the connecting rod 24, for
moving the back rest 22, in combination and for purposes herein described, and
as illustrated by drawings.
