IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1876

page_text: LETTERS PATENT to Arthur Lemuel Briggs, of Bolton, in the County of Lan-
caster, Cotton Spinner, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES."
Sealed the 15th December 1876, and dated the 12th October 1876.
PROVISIONAL SPECIFICATION left by the said Arthur Lemuel Briggs at the
Office of the Commissioners of Patents on the 12th October 1876.
ARTHUR LEMUEL BRIGGS, of Bolton, in the County of Lancaster, Cotton Spinner.
"IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS
SUBSTANCES."
My Invention is applicable to the machines in which the fleece of fibres is formed
into a lap for carding, combing, or any other preparing process.
My Invention consists in connecting the spindle, the side flanges, and the roller
on which the fleece is wound by a key on the spindle fitting into grooves in the
bosses of the flanges, and into a groove in the roller, or into grooves in bushes let
into the roller; or keys may be let into the flanges and bushes or roller, whick keys
take into a groove in the spindle, or the spindle, flanges, and roller may be locked
together in any other convenient manner.
The object of my Invention is to prevent the friction between the ends of the lap
and the side flanges, which friction injures the selvages and causes waste in unwinding
the lap.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Arthur Lemuel Briggs in the Great Seal Patent Office on the 11th April
1877.
ARTHUR LEMUEL BRIGGS, of Bolton, in the County of Lancaster, Cotton Spinner.
"IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS
SUBSTANCES."
My Invention is applicable to the machines in which the fleece of fibres is formed
into a lap for carding, combing, or any other preparing process, and it consists in
connecting the spindle, the side flanges, and the roller on which the fleece is wound

page_text: by a key on the spindle fitting into grooves in the bosses of the flanges, and into a
groove in the roller, or into grooves in bushes let into the roller; or keys may be
let into the flanges and bushes or roller, which keys take into a groove in the
spindle, or the spindle, flanges, and roller may be locked together in any other con-
venient manner.
The object of my Invention is to prevent the friction between the ends of the lap
and the side flanges, which friction injures the selvages and causes waste in un-
winding the lap.
And in order that my Invention may be fully understood, and readily carried
into operation, I will proceed to describe the accompanying Sheet of Drawings, in
which Fig. 1 is a cross section, and Fig. 2 a longitudinal section of part of an
ordinary lap machine to which my improvements are applied.
a, a, are two dotted circles representing the usual lap rollers; b, b, are the
standards supporting the sliding blocks c, c, in which the bosses of the flanges d, d,
revolve; e is the roller resting upon the lap rollers a, a, on which the fleece of
fibres is wound. I prefer to insert the long metal bush finto the roller e, but a
metal bush may be let in at each end. The bosses of the flanges d, d, and the bush
or bushes of the roller e or the roller itself (if made without bushes) are grooved or
slotted to receive the key g, which is let into the spindle h; this spindle revolves,
as usual, in the bushes i and j fitting in the sliding blocks c, c.
When the machine is at work the fleece of fibres is wound, as usual, on the
roller e, and as the roller e, the side flanges d, d, and spindle h are connected by the
key g it is evident that they all move together, and consequently no friction can
take place between the ends of the lap and the side flanges, whereas in ordinary
machines of this description, where the roller and the side flanges are not locked
together, such friction does occur to the great injury of the selvages of the lap.
My Invention may be modified by fixing keys in the roller and side flanges,
which keys fit into a groove in the spindle, or the spindle, roller, and side flanges
may be locked together in any other convenient manner.
I wish to remark here that the side flanges are set up to the end of the roller e
in the usual manner.
Having thus stated the nature and particulars of my Invention, I wish it to be
understood that I do not intend to limit myself to the details given, and that I
claim, locking the spindle, the roller, and the side flanges of lap machines together
in the manner and for the purposes described.
In witness whereof, I, the said Arthur Lemuel Briggs, have hereunto set my
hand and seal, this Seventh day of April, One thousand eight hundred and
seventy-seven.
