Improvements in and relating to Yarn Dressing Frames.
I, JOHN GARSTANG of Fulledge Mill, Burnley, in the County of Lancaster,
Manufacturer, 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 is designed, for the purpose of instantly and automatically stopping
dressing frames, when any portion of the warp becomes entangled behind the reed,
raddle, or like thread separating instrument; and also for the purpose of more
effectually dressing the warp, by the interposition of adjustable brushes, between each
section of warp, undergoing the process of dressing.
And in order that my invention may be properly understood and readily carried
into practical effect, I have hereunto attached the accompanying sheet of drawings,
marked with figures and letters of reference.
The warp or sections of warp A. B and C to be dressed, are placed beneath the
dressing frame, from whence they are drawn through the tension or weighted
rollers D, D, and D2 and thence upwards over the rods E, by which the several
sections of the warp are separated. The warp or sections of warp are then conveyed
around the stationary bars or stangs F, one sheet or section of warp being elevated
one above another, as represented on the drawings.
The warp in passing from beneath the lower cross bar F to the warp beam H, is
dressed by the brushes I, which are introduced one between each sheet or section of
warp, and adjusted in height by the screw bolts J and nuts J', so that they may
bear more or less against the warp, as may be required, during the operation of
dressing.
The warp threads, before being wound upon the warp beam H, pass between the
dents of the reed or raddle K, supported on the movable frame K', and between the
dents of the expanding and contracting comb m, mounted on the movable frame m².
These frames are connected together by link n, so that in the event of an
entanglement, the entangled or obstructed portion of the warp, in its traverse, carries
forward the raddle and the comb, bringing the latter against the blade spring o, which
being attached to the catch P depresses it in the teeth of the ratchet or cog wheel R,
by which means the dressing frame is brought to a sudden state of rest. The wheel R
for this purpose is secured to the driving shaft which is connected by spur gear to
the warp beam H. When therefore the catch P is depressed in the manner stated,
the wheel R is scotched stopping the frame, and the driving strap caused to slip or
skid upon the drum, fixed to the driving shaft, during such stoppage.
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 arrangement of mechanism, for instantly and automatically stopping
dressing frames, by the entangled or obstructed portion of the warp, substantially
as described.
2. The arrangement of dressing brushes, substantially as described.
