IMPROVEMENTS IN AND APPARATUS FOR THE CONSTRUCTION OF RING FRAME BOBBINS."
Year: 1881

page_text: LETTERS PATENT to John William Wilson, of Barnsley, in the County of
York, for an Invention of "IMPROVEMENTS IN AND APPARATUS FOR THE
CONSTRUCTION OF RING FRAME BOBBINS."
PROVISIONAL SPECIFICATION left by the said John William Wilson at
the Office of the Commissioners of Patents on the 25th May 1881.
JOHN WILLIAM WILSON, of Barnsley, in the County of York.
"IMPROVEMENTS
IN AND APPARATUS FOR THE CONSTRUCTION OF RING FRAME BOBBINS."
This Invention relates to a novel method or methods of strengthening the ring
frame bobbins at their lower extremities, and consists in there inserting a metallic
bush and securing the same in position.
This may be effected by forcing out a portion of the metallic bush by a mandril
and wedges or other suitable apparatus into the surrounding wood or other material
of which the bobbin is composed, or by screwing or otherwise fastening the
metallic bush in position.
A modification of this Invention also relates to a method of securing a metallic
ferrule at the extremity of the spools or tubes used in cotton manufactures.

the said John William Wilson in the Great Seal Patent Office on the
24th November 1881.
JOHN WILLIAM WILSON, of Barnsley, in the County of York. "IMPROVEMENTS
IN AND APPARATUS FOR THE CONSTRUCTION OF RING FRAME BOBBINS."
Fig. 1 is an half sectional elevation of a ring frame bobbin, in the lower end of
which is shown inserted a metalic tube or bush.
Fig. 2 is a similar view of a similar class bobbin, on or near the lower end of
which is shown a metalic ring.
Fig. 3 a similar view of another class of bobbin, on the upper end of which is
fixed a metalic ring similar or nearly so to Fig. 2 in the shape of metalic ring. On
the lower or bottom end is fixed a ferrule or hoop for which Letters Patent were
granted to me on the 9th day of October 1878, and numbered 3966, titled
Certain Improvements in the Construction of Bobbins, Tubes, or Spools."

Fig. 4 is a similar view of a similar class of bobbin with a similar metalic ring
on the lower end, similarly secured in part, but where the driving grooves are
cut out I lap inward against the upper side of such grooves the piece of metal so
cut, which serves the double purpose of assistant security to its fixture and a
protection to the driving groove.
Fig. 5 is a section of a press, so made and arranged to indent and secure the
tubes or bushes of Fig. 1 in three places at one operation and in a moment of time.
This apparatus can be worked by hand or power.
Fig. 6 is a side view of a pair of hand pliers for securing the metal tube or
bush after the bobbin or spool is made by indentation inside without injury.
Fig. 7 shows the end of such pliers in tube, with their ends made to fit the
inside and outside diameters of tube and bobbin. A in the several bobbin figures
represents the sectional parts of the bobbins or spools; B, the elevation of the
other half.
a, in Fig. 1, is the tube or bush which is tightly driven in when bored and in
the rough, and then placed in or under the press, Fig. 5, when the plunger c comes
down, thereby forcing outward any number of tooth indentation plates H at once;
any number of punctures or indentations are made, and so firmly fixed that nothing
but breakage will release them.
b, in Fig. 2, is a metalic ring which is made to fit very tightly on the spool
or bobbin, in the shoulder of which at c it is turned a little inward, so that when
such ring is fixed tightly down the spool or bobbin is then fixed on a mandril put
in the lathe, and while running a small roller tool is pressed into or on the edge
of the ring at c, forcing such edge inward, thus fixing it so firmly that nothing but
breakage can release it.
d, on Fig. 3, is fixed and fastened in a similar way.
h, on Fig. 4, is fixed and similarly secured in part, but where the driving grooves
are cut out the metal is cut and turned inward, forming a further security and
protection to the upper side of the groove.
Fig. 5 is an apparatus or press for indentating the whole of a tube or bush at one
stroke; c is a plunger or rod working vertically in plate D and die or bed E. In
this plunger or rod c are cut as many grooves as there are intended to be inden-
tations in tube or bush; these grooves are cut taper, as shown, from F to G; His
tooth plate kept in its proper position by the springs I pressing between grub
nut J and shoulder of spring guide pin K, which presses against the edge of steel
tooth plate H, keeps it in the taper groove in plunger or rod c; such plates H
advance or retire by the rise or fall of the rod C.

page_text: In its present shown form, as on Fig. 4, the spool A' is shown in position slipped
freely over the several tooth plates; being so held the plunger or rod c descends,
forcing by the conical grooves the several tooth plates H outward, the teeth thereby
puncturing or indenting the tube or bush; these tooth plates by the pressure of
the springs I follow the conical grooves in plunger c, advance and retire instantly
on the rise or fall of such plunger. Fig. 6 in the hand part is an ordinary pair of
pliers; in the upper jaw o' there is a tooth, the base of which is made to the
diametrical form of the inner side of the tube or bush, the lower jaw o being
made to the outer diameter of the spool or bobbin when turned. This will fasten
tube or bush in a spool when turned without injury, or fix them in old bobbins or
spools.
Fig. 7 is the end view of tube with the plier jaws.
Having described my Invention, and the several ways and modes of applying it,
I wish it to be understood that I do not confine myself to the precise details I
have had occasion to describe and refer to, as many variations may be made without
deviating from the principle or main features of this my said Invention. I know
that Letters Patent were granted to Henry Southwell on the 20th day of July
1880, and numbered 2986, titled "Improvements in the Construction of Ring
Frame Bobbins for Throstle Spinning," in which he claims the application and use
of a metalic boss.
I seek to claim nothing he has any right to or seeks to claim, but what I claim
as secured to me herein is,-
The bush or tube and apparatus for fixing same, with the several rings and
methods of securing the same, substantialy as hereinbefore set forth.
In witness whereof, I hereunto set my hand and seal, this Eigteenth day of
November, in the year of our Lord One thousand eight hundred and
eighty one.

Engineer & Patent Solicitor,

Manchester.
