IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1884

page_text: I, THOMAS HOWARD BLAMIRES of Huddersfield in the County of York Woollen
Spinner and Manufacturer do hereby declare the nature of my invention for
"IMPROVEMENTS IN LOOMS FOR WEAVING" to be as follows:-
The object of my Invention is the combining together of a certain positive cloth
taking-up motion, with a certain positive warp letting off motion, both of which
have formed the subject of seperate Patents; the first for the taking up motion
being granted to myself and others on the 4th January A.D. 1877 N° 47, and the
letting off motion granted to myself on the 23rd November A.D. 1883 N° 5495.
The present Invention consists in combining the said positive taking-up motion,
with positive letting off motions, so that the letting off and taking up motions
work connectively together, the cloth being taken up at the same ratio or nearly
the same ratio at which the warp is let off or delivered, the relative speeds of
which being regulated and determined by suitable change gearing.
By this combination and arrangement I dispense with weights and cords, and
other devices which have previously been used to get the desired tension on the
warp in the letting off notion.
In order to carry out my Invention I employ a continuously revolving roller or
rollers upon which the warp beam rests, and the warp is unwound therefrom by
surface contact as described in my Specification N° 5495 A.D. 1883, the said
revolving roller or rollers being driven positively by means of bevil, spurr, worm
or other suitable driving gear and diagonal or straight shaft from the sand or
friction roller which takes up the cloth; or the revolving roller may be driven
from any other convenient part of the loom.
The sand or friction roller receives its positive motion by shaft and gearing from
the crank shaft as described and shewn in the Drawings of Patent N° 47 A.D. 1877,
granted to me and others.
By the combination of these two positive motions, I find they harmonize and
work together in equal proportions, whilst the cloth produced is superior, being
perfectly even and uniform throughout which is not the case where either the
letting off or taking up motions are seperate, variable or intermittant.

page_text: Having only made reference to the letting off motion and taking up motion in
my former Patents seperately, I find it necessary to make application for another
Patent which combines the double arrangement of positive taking up with positive
letting off motions, where either single or double warp beams are employed.

page_text: I, THOMAS HOWARD BLAMIRES of Huddersfield in the County of York, Spinner
and Manufacturer do hereby declare the nature of my invention for "IMPROVE-
MENTS 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 :-
The object of this invention is the combining together of a certain positive cloth
taking up motion, with a certain positive warp letting off motion, both of which
have formed the subject of separate Patents; the first for the taking up motion
being granted to myself and others on the 4th of January A.D. 1877 No 47 and the
letting off motion granted to myself on the 23rd of November A.D. 1883 N° 5495.
The present invention consists in combining the said positive taking up motion
with the positive letting off motion, so that the letting off and taking up motions
work connectively together, the cloth being taken up at the same ratio or nearly
the same ratio at which the warp is let off or delivered, the relative speeds of which
being regulated and determined by suitable change gearing.
In order to carry out my invention I employ a continuously revolving roller or
rollers upon which the warp beam rests, and the warp is unwound therefrom by
surface contact as described in my Specification N° 5495. A.D. 1883, the said
revolving roller or rollers being driven positiveley by means of bevil, spur, worm,
or other suitable driving gear and diagonal shaft from the sand or friction roller
which takes up the cloth; or the revolving roller may be driven from any other
convenient part of the loom. The sand or friction roller receives its positive
motion by shaft and gearing from the crank shaft as described and shewn in the
drawings of Patent No 47 A.D. 1877 granted to me and others.
Having only made reference to the letting off motion and taking up motion
in my former Patents separately, I have found it necessary to make application for
another Patent, which combines the double arrangement of positive taking up with
positive letting off motions.
In order that the invention may be better understood I herein give reference to
the accompanying sheet of drawings wherein Fig 1 is elevation of so much of a
loom as is necessary to illustrate my improvements, Fig 2 is end view thereof,
and Fig 3 detached plan.
A is framing of loom, B the crank shaft, and C the warp beam which it will be
seen is resting or bearing upon the delivery roller D, and receives a continuous
rotary notion from the sand beam or friction roller U by means of the bevil
wheels G on the end of the diagonal shaft E, which is driven by wheel G¹ on the
end of the sand roller gearing with the worm wheel F.
The taking up or sand beam receives its motion from the crank shaft by bevil
wheels H, shaft I, worm J, wheels K and K¹ and train of gearing L so that the
rotary motion of the crank shaft is conveyed to the taking up roller, and from the
taking up roller it is conveyed by diagonal shaft G to the delivery roller D which
by surface contact unwinds the warp from the beam in the same ratio or nearly the
same as the cloth is woven and taken up, the relative speeds of which are
determined by changing the bevil wheels G and the pinion wheel K¹ working on
the same axis as the wheel K.
By this means the taking up and delivery of the warp are combined, the quantity
of warp delivered being determined by the quantity taken up, consequently the
warp is delivered with mechanical accuracy whatever may be the varying diameter
of the warp beam, consequently producing regular, even, and superior cloth from
end to end of the warp.

page_text: It is well known in practice that after a loom is thrown off, that it does not
immediately stop, but the momentum it has received causes it to make one or two
revolutions; in order therefore to prevent any movement of the taking up roller
after the loom is thrown off by the weft fork on the breakage of weft, I employ a
retaining catch S attached to a bracket T which also supports the shaft I. A shaft
or rod V is placed across the machine having one end cranked (as shewn in plan
view) and passing underneath the shaft I whilst on the other end of the rod V is a
lever arm W standing in an upright position so that its upper end is against the
ordinary knocking off lever ✗. It will therefore be seen that when the weft is
broken or absent from other causes, that the lever X will be drawn in the ordinary
manner in the direction of the arrow, which will push the lever W: sideways,
causing the rod V to rock upon its centre, whereby the cranked end will lift the
shaft I and remove the wormi J from contact with the wheel K, throwing the parts
out of gear and immediately stopping any further movement of the taking up
beam, the catch S in the teeth of the wheel K meanwhile preventing the said
wheels from running back.
When weaving a soft beamed warp I provide that the full weight of the warp
beam does not bear heavily upon the roller D, and for that purpose I arrange that
the two centres are not in a vertical line, but that one centre is off side of the
other centre, and in addition to this, the shafts or studs on the end of the warp
beam bear and rest upon the adjustable inclined bars M by which means the
greatest portion of the weight of the beam is not borne by the warp, but rests
upon and is supported by the ends of the beam so that the full roundness and
diameter of the warp is not reduced by excessive pressure whether the loom be
standing or running. The position of the inclined bars M being regulated by
Screws (b.
In order to give a certain amount of tension to the warp for weaving purposes
two or more friction rods or bars N are employed each end of which are supported
by swivelling brackets O and when the position of the two rods are fixed a catch c
working on a stud in the loom frame is placed into gear with the ratchet wheel d
on the stud carrying the brackets O whereby the rods are held in position.
The warp in passing from the beam into the "shed" passes in contact with bars N
the position of. which can be altered by moving the brackets O upon their centres
to any desirable angle, by which means the friction on the warp can be regulated
accordingley-When the bars N are not required to act as friction bars, the thumb-
screws bare unscrewed, and the brackets O placed in a vertical position so as to
avoid any friction.
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 of a positive letting off motion (where the warp is resting
upon and unwound by the frictional contact of a rotary drum) with a positive
taking up motion (where the sand beam is driven continuously by the crank shaft)
in manner substantially as herein described and shewn.
