Year: 1878

page_text: LETTERS PATENT to John Smith, of Carshalton, in the County of Surrey, for
the Invention of "IMPROVEMENTS IN SILK BOLTING REELS."
PROVISIONAL SPECIFICATION left by the said John Smith at the Office of
the Commissioners of Patents on the 16th September 1878.
JOHN SMITH, of Carshalton, in the County of Surrey.
BOLTING REELS."
"IMPROVEMENTS IN SILK
My Invention relates to improvements in the construction of silk bolting reels
for dressing meal, flour, offal, middlings, drugs, and other materials.
In these reels as usually constructed the silk, wire, or other clothing is carried on
horizontal ribs or bars attached to the ends of arms projecting from the centre boss
of the reel, or to circular bands or rings connecting the ribs or bars together.
My Invention consists in attaching springs of india-rubber, steel, wire, or other
elastic inaterial to the ends of the arms or to the horizontal ribs or bars, at suitable
intervals and in line horizontally with each other. Over the outer ends of these
springs are laid horizontal ribs or bars of steel or iron, on which the silk is carried. .
One or more studs or bolts connect each of these ribs or bars at each spring with
the end. of the arm, or with the fixed rib or ring above named, so as to support or
confine each spring and at the same time retain the outer rib or bar thereon at its
proper normal radial distance.
By this means a certain amount of spring or elasticity which is indispensable to
the proper bolting or dressing of the materials above named is given to the silk.

My Invention consists in attaching springs of india-rubber, steel wire, or other
elastic material to the horizontal ribs or bars at suitable intervals, and in line with
each other, or to the ends of the arms, by which means a certain amount of spring
or elasticity which is indispensable to the proper bolting or dressing of the
materials named is given to the silk.
And in order that my said Invention may be well understood, I shall now pro-
ceed more particularly to describe the same, and for that purpose shall refer to the
several Figures on the accompanying Sheet of Drawings, like letters of reference
indicating corresponding parts in all the Figures.
Figure 1 is a side elevation of a silk bolting reel constructed according to my
Invention, and Figure 2 an end view thereof.
A, A, are the horizontal ribs or bars as usually arranged for carrying the silk
wire or other clothing of a silk bolting reel, and which are attached to the ends of
the arms B, B, projecting from the centre bosses B¹ carried by the shaft B² as shewn,
or otherwise mounted as desired. C, C, are springs of steel wire placed on the
outer edges of the horizontal ribs or bars A, A, at suitable distances apart, and on
the outer ends of these springs C, C, are laid the horizontal ribs or bars D, D, of
steel or iron, on which the silk wire or other clothing E is carried as shewn.
The horizontal ribs or bars D, D, are retained on the springs C, C, and with the
latter, to the inner horizontal arms A, A, by means of studs or bolts F, F, secured
by nuts and washers G, and acting in such a manner that whilst supporting and
confining the springs C, C, and at the same time retaining the outer ribs or bars
D, D, at their proper normal radial distances, the latter are capable of a giving or
yielding action by the compression of the springs C, C, whereby the required spring
or elasticity is given to the silk as before mentioned. Figure 3 shows an alternative
method in which the springs C, C, and studs F, F, in lieu of being secured to the
horizontal ribs or bars A, A, are carried by lugs H projecting from shoes or brackets
I secured directly to the ends of the arms B, B, as shewn, in which case the hori-
zontal ribs or bars A, A, are dispensed with.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider novel and original, and
therefore claim as the Invention secured to me by the herein-before in part recited
Letters Patent is.-
Carrying the silk, wire, or other clothing of silk bolting reels on horizontal ribs
or bars supported on springs placed between them and the fixed horizontal bars or
arms of the reel, substantially as and for the purpose herein-before described, and
illustrated by the accompanying Drawing.
In witness whereof, I, the said John Smith, have hereunto set my hand and
seal, this Thirteenth day of March, in the year of our Lord One thousand
eight hundred and seventy-nine.
