CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1878

page_text: LETTERS PATENT to John Pilling, of Rochdale, in the County of Lancaster,
Cotton Spinner and Manufacturer, and Samson Booth, of the same Place,
Loom Overlooker, for the Invention of "CERTAIN IMPROVEMENTS IN LOOMS
FOR WEAVING."
Sealed the 18th April 1878, and dated the 23rd February 1878.
PROVISIONAL SPECIFICATION left by the said John Pilling and Samson
Booth at the Office of the Commissioners of Patents on the 23rd February
1878.
"
JOHN PILLING, of Rochdale, in the County of Lancaster, Cotton Spinner and
Manufacturer, and SAMSON BOOTH, of the same Place, Loom Overlooker. CERTAIN
IMPROVEMENTS IN LOOMS FOR WEAVING."
Our Invention consists, first, in an improved mode of constructing the bearings of
the heald roller shaft, whereby the healds are kept to the requisite tension while a
certain amount of elasticity is obtained. The bearings are made of wood, and they
fit in the sockets of brackets fixed to the cross rail on the top of the loom connecting
the two end frames; in each socket is a packing of vulcanized india-rubber on
which the wood bearings rest. These improved elastic bearings make the healds
last much longer, render the treading tappet and bowls more durable than heretofore,
and the loom takes less power to turn it.
Our Invention consists, secondly, in an improved arrangement of parts for relieving
the shuttle before it is picked, whereby a great saving in wear and tear and in power
is effected. To accomplish this we mount a double lever on a bracket and stud fixed
to one of the slay swords; one end of this lever is connected by a wire to a screw
on one of the crank arms, and the other end is connected by a spring to a hook on
the stop rod, to which the fingers acting on the swells are fixed.

"
JOHN PILLING, of Rochdale, in the County of Lancaster, Cotton Spinner and

IMPROVEMENTS IN LOOMS FOR WEAVING."
Our Invention consists, first, in an improved mode of constructing the bearings of
the heald roller shaft, whereby the healds are kept to the requisite tension while
a certain amount of elasticity is obtained.
And, Secondly. In an improved arrangement of parts for relieving the shuttle
before it is picked, whereby a great saving in wear and tear and in power is
effected.
And in order that our Invention may be fully understood and readily carried
into operation, we will proceed to describe the accompanying Sheet of Drawings.
Fig. 1 is an elevation partly in section, and Fig. 2 a plan, of one of our improved
bearings for the heald roller shafts of looms.
a is the end of the shaft, and a' the roller to which the healds are suspended as
usual. The bearings consist of the blocks b made of wood or other suitable material,
fitting in the sockets c of the brackets d, which are fixed to the cross rail on the
top of the loom or to any other part of the framing; in each socket c is a packing
of vulcanised india-rubber e, on which the wood or other bearings b rest. These
improved elastic bearings make the healds last much longer and render the treading
tappets and bowls more durable than heretofore, the loom also takes less power to
drive.
Fig. 3 represents our improved arrangement of parts for relieving the shuttle
before it is picked. To accomplish this we mount the double lever f on a bracket
and stud fixed to one of the slay swords g; one end of this lever is connected by the
wire link to a screw on one of the crank arms i, and the other end is connected
by the spring to a hook on the stop rod k, to which the fingers acting on the
swells are fixed. When the shuttle is in the shuttle box the spring is distended
by the double lever f, as shewn in the Drawing, to hold the shuttle; but before the
pick is given the crank arm is lowered, and the spring ; then releases the finger 1 to
allow the shuttle to be thrown across the shed. By this means a great saving in the
wear and tear and in power is effected.
Having thus stated the nature of our Invention and described the manner of
performing the same, we declare that we claim,-
First. The improved mode of constructing elastic bearings for the heald roller
shaft, as shewn and described.
And, Secondly. The improved combination of machinery shewn and described for
releasing the shuttle before picking.
In witness whereof, I, the said Samson Booth, for myself and on behalf of
the said John Pilling, have hereunto set my hand and seal, this Twentieth
day of August, One thousand eight hundred and seventy-eight.
