Improvements in Machinery Employed in the Manufacture of Wire
Hooks for Mill Bands.
I, GEORGE WALKER HIGHLEY trading as Watson Brothers, of North Parade,
Halifax, in the County of York, Card Maker, do hereby declare the nature of this
invention to be as follows:
-
This invention relates to machinery employed in the manufacture of wire hooks
for attaching the opposite ends of mill bands used on spinning and other like frames,
and consists of a combination of appliances for bending and shaping the hooks,
and for grinding or pointing the ends of said hooks.
According to this invention, there is employed a rising or falling block or anvil,
against which a length of wire is fed from a winch; a presser forces the wire
against the anvil, and whilst so held, the length of wire is cut off, whereon a pair
of crookers bend the ends of the wire along the sides of the anvil, thereby forming
a staple, the ends of which project beyond the anvil. The crookers now retire
and a pair of grinders consisting of two revolving spindles having their ends split
or. divided into three or four parts, are advanced so as to enclose the ends of the
staple, and by their rapid rotation to grind or point the staple. The crookers now
advance, and by a further movement round the anvil, fold the staple into its
finished form, and the anvil is lifted or raised as before, and so passes the book off
the anvil.
The requisite movements. to the crookers, knife, or cutting tool, is imparted by
means of tappets and return springs, and so likewise are the revolving grinding
spindles operated.
The back of the anvil is either plain, hollow, or of any form to which it is
desired the crown of the hooks shall be shaped.

Improvements in Machinery Employed in the Manufacture of Wire
Hooks for Mill Bands.
J, GEORGE WALKER HIGHLEY, trading as Watson Brothers, of North Parade,
Halifax, in the County of York, Card Maker, do hereby declare the nature of this
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 machinery employed in the manufacture of wire hooks
for attaching the opposite ends of mill bands used on spinning and other like frames,
and consists of a combination of appliances for bending and shaping the hooks, and
for grinding or pointing the ends of the said hooks.
According to this invention, there is employed a rising or falling block or anvil,
against which a length of wire is fed from a winch; a presser forces the wire

page_text: against the anvil, and whilst so held, the length of wire is cut off, whereon a pair
of crookers bend the ends of the wire along the sides of the anvil, thereby forming
a staple, the ends of which project beyond the anvil.
The rookers now retire, and a pair of grinders consisting of two revolving
spindles having their ends split or divided into three or four parts, are advanced
so as to enclose the ends of the staple, and by their rapid rotation, to grind or
point the staple. A second pair of crookers now advance, and fold the staple into
its finished form, and the anvil is lifted or raised as before, and so passes the hook
off the anvil.
The requisite movements to the crookers, knife or cutting tool, are imparted by
means of tappets and return springs, and so likewise are the revolving grinding
spindles operated.
The back of the anvil is either plain, hollow, or of any form to which it is
desired the crown of the hooks shall be shaped.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which
Fig. 1 is a plan view of the improved machinery for purpose aforesaid.
Fig. 2 is a side elevation of Fig. 1.
Fig. 3 is a sectional side elevation of the moveable anvil, presser, and grinder.
Fig. 4 is a plan view of Fig. 3 shewing also the two pairs of crookers, and the
ends of the hook being ground by the grinders.
Fig. 5 is a similar view to Fig. 4, but the second pair of crookers are shewn
putting the finishing bend on the hook.
Fig. 6 is an end view of one of the grinders, and Fig. 7 is a view of one of the
finished hooks.
The
According to this invention, the wire 1 from which the hooks 2 are to be made
is carried on a winch, and drawn therefrom by a lever or finger A to which an
intermittent to and fro, and up and down motion is imparted by the tappet B and
cam C so that such finger moves along the wire lays hold of same and draws a
length along in a manner similar to the feed employed in a card setting machine.
The wire 1 passes through the guide 3 where it is cut off by one of a pair of
crookers 4. 4 which are now advanced by a tappet 5 on the main shaft 6.
crookers 4. 4 are carried in a frame 7, and are hinged at 8. 8, and their outer ends
are held together by means of a spring 9. When the crookers 4. 4 are advanced,
the presser or tonge 10 is also advanced, by the tappet 13, and presses the crown
part 11 of the hook against the recessed anvil 12, and the crown of the hook is
recessed or curved as shewn (see Fig. 4). The crookers 4. 4 force the ends of the
wire partly around the anvil 12 into the form shewn by Fig. 4, i.e., a staple, and so
far the operation is very similar to the formation of a dent or tooth by a card
setting machine. Before the crookers 4. 4 leave the ends of the staple, a slight
inward pressure is imparted to the crooking ends of same, by means of the
fingers 14. 14 on the shaft 15, to which a partial rotation is given by the lever 16
and tappet 17. This partial rotation causes the fingers 14. 14 to move to, aud
press against the inclines 18. 18 on the crookers 4. 4, and their opposite ends
are moved slightly towards each other, and the staple is then slightly pressed, so
that when the crookers 4. 4 leave it, the staple does not spring open. Before the
crookers 4. 4 leave the staple, a pair of rotatory reciprocating grinders 19. 19
driven by gear wheels 20, pulley 21, and strap from any going part of the
machine, are by springs 22 moved forwards in the slide bed 23, so that the ends of
the grinders 19 grind and point the ends of the staple. After the ends are
pointed, a tappet 24 on the shaft 6, acting on a rod 25, pushes the latter
backwards, and this rod 25 is connected to the slide 26 in which the rotatory
grinders 19. 19 are carried, and which slides in the bed 23, so that the grinders
are moved clear of the staple.
When the grinders 19.-19 have left the staple, a pair of crookers 26* 26^ are
moved forwards, and their ends bend the pointed ends of the staple towards each

page_text: other, and the hook is completed (see Figs. 5 and 7). The crookers 26* 26ª are
respectively operated as follows:-One crooker 26ª is operated by the crank
lever 27 mounted on a stud, and by link 28 connected to the lever 29 operated by
nug 30 on the gear wheel 31, and the other crooker 26 is operated by lever 32,
which is moved on its fulcrum stud by the lever 33, which is operated by a nug
on the face of the wheel 34 on the shaft 6.
When the hook is completed, the anvil 12 is raised by the lever 35 connected by
link 36 with the lever 37, which is operated by a tappet on the shaft 6, and the
finished hook falls into a receptacle provided for it.
Return springs are employed to bring the several parts to their normal position
after being moved by the tappets on the main driven shaft 6.
The grinders 19. 19 are similar to two spindles, the ends of which are recessed
and cut or split (see Sheet 3), and the ends of the staple to be ground are received
in the recessed portion, and the grinders revolving rapidly, the ends of the staple
are cut or ground and pointed.
The springs 38. 38 allow the grinders a little play, so as to give, if necessary,
when grinding the points of a staple.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The improvements in machinery for purpose set forth, comprising the
pointed presser piece 10, hollow anvil 12, crookers 4. 4, grinders 19, and crookers 26ª,
all in combination, and as fully described herein and illustrated by the drawings
annexed.
(2) The revolving grinders 19. 19, and a holding device such as parts 10 and 12,
as herein fully described and substantially as illustrated by the accompanying
drawings.
