Improvements in Shields or Hoops for Spools and Bobbins.
We, WALTER BENNETT WILSON, of Beevor Works, Barnsley, in the County of
York, Bobbin Maker, and MESSIEURS WILSON AND COMPANY, BARNSLEY, LIMITED,
of Beevor Works, Barnsley aforesaid, Bobbin Makers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the shields or metal hoops applied to bobbins and
spools of wood, and the object is by means of spaced teeth or prongs extending
from such hoops to so secure the said hoops that they cannot either turn round
on the bobbin, or be stripped or pulled off same.
According to this our said invention, we employ a hoop: one edge of which
is turned inwards and provided with spaced pins or prongs at intervals of its
circumference. The hoop is then fitted into the bobbin or spool, and the pins
or prongs are then bent and forced at about right angles to the hoop so as to
act as holders which prevent the hoop from becoming loose and either admitting
of its turning round on the bobbin or spool, or being stripped or pulled endwise
off the spool or bobbin. The said pins or prongs when so constructed and applied
affording a convenient and ready means of providing against the two defects of
hoops as heretofore applied and fitted, i.e. turning round on the bobbin or spool,
or being stripped off the latter.
We are aware that hoops provided with spaced pins lineable with the hoops
have been used so that when forced into the bobbin, have had the effect of pre-
venting rotation or turning of the hoop, but such afforded no protection or hold
whatever as a means of preventing the hoop being stripped off the bobbin or
spool; and to such application we lay no claim, and we are aware that metal
hoops having serrated rims have been employed, and that the teeth or serrations
have been bent over a beading or shoulder of the bobbin, whereby the stripping
off of the hoop was prevented, but such application did not prevent the hoop
becoming loose and turning round on the bobbins or spools.
Dated this 4th day of December 1896.

Improvements in Shields or Hoops for Spools and Bobbins.
We, WALTER BENNETT WILSON, of Beevor Works, Barnsley, in the County of
York, Bobbin Maker, and MESSRS. WILSON & Co. BARNSLEY LIMITED, of Beevor
Works, Barnsley aforesaid, Bobbin Makers, do hereby declare the nature of this

page_text: invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to the shields or metal hoops applied to bobbins and
spools, and the object is by means of spaced teeth or prongs extending from such
shields or hoops to so secure the said shields or hoops that they cannot either turn
round on the bobbin or spool, or be stripped or pulled endwise off the same.
Such being the nature and object of our said invention, the following is a
complete description of same, reference. being had to the accompanying drawings,
in which:-
Fig. 1 is an elevation, partly in section, of a bobbin or spool such as used in
ring spinning.
Fig. 2 is a plan view of the lower part of the shield or hoop.
Fig. 3 is an example of the invention as applied to a worsted spinning bobbin.
Fig. 4 is a section of the shield or hoop, the teeth or prongs being straight.
Fig. 5 is same at next stage of manufacture, the shield or hoop being cupped
from the outside, the teeth or prongs having a slight lead inwards..
Fig. 6 is a like view to Fig. 5, but the teeth or prongs are pressed from inside
so as to give more lead inwards.
At 1 is the bobbin, 2 is the shield or metal hoop, 3, 3 are the spaced teeth or
prongs, which it will be seen (unlike the teeth or prongs as heretofore made
linable with the hoop) are made the opposite way or at right angles to the shield
or hoop, and that the shield or hoop so made is doubly locked on the bobbin or
spool so as to prevent the shield or hoop either turning round or being stripped
endwise off the bobbin or spool.
As on examination of Fig. 2 it will be seen that if the improved manufacture
of the shield or hoop were completed before actual application to the bobbin or
spool, then the shield or hoop could not he got into the requisite position on the
bobbin or spool, hence it is necessary that the completing operations in the
manufacture of the said shield or hoop are performed after the shield or hoop
is in position on the hobbin or spool, and is doubly locked in position thereon,
and which is effected as follows-The shield or hoop having spaced straight pins
as illustrated at Fig. 4 is made by punching or stamping as ordinary. The points
of the teeth or prongs are now to be cast over or bent slightly inward as shown
at Fig. 5 and advanced a further stage as per Fig. 6, then the base of the bobbin
or spool at e is to be turned down until small enough to be forced in between
the bent over points of the teeth or prongs and the bent portions c and d of the
shield or hoop whereon a mandril is applied through the centre of the shield
or hoop at h so as to form the portion and force the prongs 3, 3, 3, 3 outwards
and into the wood of the bobbin or spool at or about right angles to the bore
and length of the latter, and nipping the base e of the bobbin or spool, within
the J bend of the shield or hoop, so that the bobbin is pierced by the
teeth or prongs in the bore at a distance beyond its base or end, and also the base
or end is further and better bound and held together by the J bent portion of the
shield or hoop as described.
The example of worsted bobbin shews elevation only, the shield or hoop 2
being constructed and applied as described in relation to the ring bobbin or
spool, and so likewise to whatever class of bobbin or spool this invention may
be applied, and whether of wood or paper mache it must be provided that there
is no endwise puncturing of the wood or papier mache and that the J bent portion
of the shield or hoop is to hold, confine, and nip the base or upper end of the
bobbin, and that the teeth or pins are to be inserted at a distance from the end
or base of the bobbin and act as double locking devices which so hold the shield
or hoop in position on the hobbin or spool that the said shield or hoop can neither
turn round on or be withdrawn from the end of the hobbin or spool.
The teeth or prongs may be formed on the upper and outer rim of the shield
or hoop at k and applied as described, but we prefer to apply to inside of bobbin
or spool as described and illustrated.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
Shields or hoops having prongs or teeth which pierce the bobbin or spool at
right angles to the length and grain thereof and at a distance from the end
whilst the J bend of the hoop or shield confines and nips the end of the bobbin
or spool and as herein described and illustrated by drawings annexed.
