IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1882

page_text: LETTERS PATENT to David Bailey, of Yews, Lockwood, in the County of
York, Loom Tuner, and now in the employment of Messrs. Robert Taylor
and Sons, of Marsden, near Huddersfield, in the said County of York, for an
PROVISIONAL SPECIFICATION left by the said David Bailey at the Office
of the Commissioners of Patents on the 7th March 1882.
DAVID BAILEY of Yews Lockwood in the County of York Loom Tuner and
now in the employment of Messrs Robert Taylor & Sons of Marsden near
Huddersfield in the said County of York "IMPROVEMENTS IN LOOMS FOR
WEAVING"
The improvements relate to means for stopping the loom when weft breaks or
fails.
When the slay board works a lever from an axis carried by the race is brought
in contact with a compound lever to lift a lever or finger attached to the weft fork
so as to allow the shuttle to pass. As the slay-board advances this compound
lever is acted upon by an incline and gets clear of the lever above referred to from
the axis carried by the race and thus brings another arm or lever from the axis
carried by the race in such a position as to cause the weft fork to rest on the
weft which when whole keeps up a rod attached to another arm from the axis
carried by the race clear of effecting the knocking off.
When the weft breaks the rod just referred to catches a projection or stop and
in the backward movement of the slay board the motion of the loom is immediately
stopped.
By another arrangement in place of a rod attached to the other arm above referred
to from the axis carried by the race which rod is to be held clear of or so as to be in
a position to act on a projection or stop on a moving piece to act on the weft fork
and thus effect the stoppage of the loom, I employ a catch lever turning on an axis
carried by the batten or going part of the loom the catch end of which lever is
supported by a connecting rod from the other arm or lever before referred to from
the axis carried by the race so as to be able readily to stop the loom when
required.

lever j is supported to turn upon a pin ja from the bracket a¹.
When the weft breaks the lever arm e operates the shaft c and thence the
lever f to the catch lever j to catch on projection or notch k¹ on the bark and then
the backward movement of the slay board carries the bark against one end of the
lever to act on the stop rod lever m and thus operates to stop the loom.
Figures 4 and 5 show a modification of the above. In this case the lever arm f
supports a rod n so that the rod n may be held clear of or so as to be in position
to act on the projection k¹ of the moveable piece k and thence by the lever ỉ on the
stop rod lever m to effect the stoppage of the loom.
Having thus described my Invention and means which I adopt in carrying the
same into effect I would have it understood that what I claim is-The arranging
or combining parts in connection with looms for weaving adapted readily to effect
the stoppage of the loom when weft breaks as described.
In witness whereof I the said David Bailey have hereunto set my hand
and seal this Second day of September One thousand eight hundred and
eighty two.
