IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1879

page_text: LETTERS PATENT to Henry Lomax, of Darwen, in the County of Lancaster,
Machinist, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said Henry Lomax at the Office
of the Commissioners of Patents on the 13th August 1879.

MENTS IN LOOMS FOR WEAVING."
"IMPROVE-
This Invention relates to improved apparatus for controlling and regulating the
letting off the warp from the beam, and improved apparatus for easing the beam
when necessary without removing the weights, and for lacking or binding the warp
beam during the beat up.
According to this my said Invention I attach to the back bearer or to a cross-
bar a slotted lever, a cross arm of which rests against the yarn on the beam; from
the lever is a finger, to which one end of chains or cords are attached, thence pass
over guides to the beam weights, the latter being free to move along inclined
weighting levers so that as the beam decreases in diameter the chains or cords
admit of the movement of the weights along the weighting levers, so adjusting the
weighting of the beam; the slot in the lever first hereinmentioned admits of the.
vibration of the beam, and prevents the cross arm rubbing the yarn.
For easing the weighting of the beam there is a band lever and eccentric applied
to the weighting lever, whereby the weights can be lowered so as to rest on the
ground and instantly raised again when the loom is restarted.
The warp beam is braked or held stationary during the beat up of the slay by
means of a lever and brake, operated through the momentum of the slay or other
going part of the loom.

IMPROVE-
This Invention relates to improved apparatus for controlling and regulating the
letting off the warp from the beam, and improved apparatus for easing the beam
when necessary without removing the weights, and for locking or binding the
warp beam during the beat up.

According to this my said Invention I attach to the back bearer or to a cross
bar a slotted lever, a cross arm of which rests against the yarn on the beam;
the lever is a finger to which one end of chains or cords are attached, thence pass
over guides to the beam weights, the latter being free to move along inclined
weighting levers, so that as the beam decreases in diameter the chains or cords
admit of the movement of the weights along the weighting levers, so adjusting the
weighting of the beam; the slot in the lever first herein mentioned admits of the
vibration of the beam and prevents the cross arm rubbing the yarn.
For easing the weighting of the beam there is a hand lever and eccentric applied
to the weighting lever, whereby the weights can be lowered so as to rest on the
ground, and instantly raised again when the loom is restarted.
The warp beam is braked or held stationary during the beat up of the slay by
means of a lever and brake operated through the momentum of the slay or other
going part of the loom.
Such being the nature and object of this my said Invention, I will now proceed
to describe the nature and particulars thereof, and in order that the same may be
clearly understood I have hereunto annexed a Sheet of Drawings illustrative
thereof, and have marked the several views or figures with letters of reference,
a like letter indicating a like part in the several views or figures.

page_text: without the necessity of removing the weight from the lever, the handle J being
raised again will at once elevate the weight as before to its working position.
For breaking or holding the beam steady during the beat up of the slay I
employ a strap, clip, or rope N (Fig. 5) passed round the ruffle of the beam, one
end being secured thereto, the other end of the strap clip secured to a lever P near
its fulcrum R. At S is the slay sword connected to the lever P by means of
adjustable rod T, so that when the slay swords and reed are forward in the act of
beating up the weft the lever P will by the rod T be moved on its fulcrum, and the
projecting finger W. act on the lug Y to which the clip or rope Z is attached, so
coupling the neck or ruffle of the beam at each beat up and steadying the beam as
explained.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be or may be performed, I would
have it understood that I do not claim any of the parts hereinbefore described
separately or apart from the combination thereof in my improved loom; but what
I do claim as the Invention secured to me by the hereinbefore in part recited
Letters Patent is,-
Firstly. The lever B applied and combined, and operating with the weight and
weighting lever in manner as shown and herein described.
Secondly. The apparatus for lowering and raising the lever weights, as described
and illustrated.
Thirdly. The combination of strap or clip and lever illustrated by Figure 5,
operated in manner and for purpose described.
In witness whereof, I, the said Henry Lomax, have hereunto set my hand
and seal, this Ninth day of February, in the year of our Lord One thousand
eight hundred and eighty.
