IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1881

page_text: LETTERS PATENT to William Atherton, of the Firm of Atherton Brothers, of
Preston, in the County of Lancaster, Machine Makers, for an Invention of
"IMPROVEMENTS IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said William Atherton at the
Office of the Commissioners of Patents on the 7th July 1881.
WILLIAM ATHERTON, of the Firm of Atherton Brothers, of Preston, in the
County of Lancaster, Machine Makers. "IMPROVEMENTS IN LOOMS FOR WEAVING."
This Invention has reference to the mode of securing the outer roughened or
perforated metal covering to the taking up beams or rollers employed in looms for
weaving.
According to my Invention a bar of wood is fitted within the ordinary sheet
metal tube forming the roller in such manner that the outer perforated covering
may be attached to the roller by means of nails or tacks driven through the thin
sheet metal of which the roller is composed into the two outer edges of the
wooden bar. The ends of the wooden bar are held within suitably formed grooves
cut into or jaws projecting from the inner sides of the two discs or plates forming
the ends of the taking up beam or roller.
By the employment of a wooden bar arranged within the roller or beam, as
above described, increased rigidity and strength are imparted to the roller, whilst
more convenient means than heretofore provided are afforded for receiving the
nails or tacks employed in fastening on the outer covering.

by the said William Atherton in the Great Seal Patent Office on the
6th January 1882.
WILLIAM ATHERTON, of the Firm of Atherton Brothers, of Preston, in the
County of Lancaster, Machine Makers. "IMPROVEMENTS IN LOOMS FOR WEAVING."
This Invention has reference to the mode of securing the outer roughened or
perforated metal covering to the taking up beams or rollers employed in looms for
weaving. According to my Invention a bar of wood is fitted within the ordinary
sheet metal tube forming the roller in such manner that the outer perforated
covering may be attached to the roller by means of nails or tacks driven through
the thin sheet metal of which the roller is composed into the two outer edges of
the wooden bar. The ends of the wooden bar are held within suitably formed
grooves cut into or jaws projecting from the inner sides of the two discs or plates
forming the ends of the taking up beam or roller.
In the accompanying Drawings Fig. 1 is a side elevation; Fig. 2, a cross section;
and Fig. 3, a transverse section of the end portion of a taking up beam or roller.
a is a bar of wood fitted within the sheet metal tube b around which the outer
perforated covering is wound, and fastened by means of tacks driven through into
the wooden bar a (as shown in Fig. 7). c is a disc or plate forming one end of
the roller provided with the jaws d projecting from the inner side of the disc
within which one end of the wooden bar a is fitted; the other end of the wooden
bar being fitted into corresponding jaws at the other end of the roller; Fig. 4
illustrates an arrangement in which the inner bar is composed, partly of iron and
partly of wood, the portion e being of iron, and the portions ff, being of wood;
Fig. 5 shows a modification of the same arrangement designed to give greater
rigidity to the body of the roller; Fig. 6 shows a further modification, g being an
iron hoop into which the wooden bar a is secured as shown, a suitable number of
the hoops being inserted within the roller tube, thereby forming a roller of great
strength and rigidity. The opening admits the lap-joint which is shewn
enlarged at Fig. 8.
By the employment of a wooden bar, or a bar partly of iron and partly of wood,
arranged within the roller or beam as above described, increased rigidity and strength
are imparted to the roller whilst more convenient means than beretofore provided
are afforded for receiving the nails or tacks employed in fastening on the outer
covering.
The above described construction of roller is obviously applicable to rollers
generally, the outer covering of which consists of a sheet metal tube.
Having now described the nature of my said Invention and the mode of carrying
it into practical effect, I would have it understood that what I consider to be novel
and original, and therefore claim as the Invention secured to me by the herein-
before in part recited Letters Patent is, the mode of constructing taking up beams
or rollers, substantially as above described and shewn in the Drawings for the
purpose specified.
In witness whereof, I, the said William Atherton, have hereunto set my hand
and seal, this Fifth day of January, in the year of our Lord One thousand
WILLIAM ATHERTON. (L.S.)
