COMPLETE SPECIFICATION.
An Improved Method of Attaching the Knob or Handle to Knitting
Pins, Tricot, or Crotchet Hooks.
I, GEORGE LEWIS, Clive Works, Redditch, Needle Manufacturer, trading as'
Lewis & Baylis, 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 :-
My invention is an improved method of attaching the knob or handle to knitting
pins, tricot, or crotchet hooks, whether these be made of wood, bone, ivory, or
metal. To carry out this my invention, instead of the usual bone or wood knobs
in common use, I take hollow knobs, made (by the ordinary and well known process
of stamping) out of sheet brass, copper, German silver, or other suitable metal, and
of a globular shape. On what I may call the underneath of these hollow metal
globes is a hole, which 1 cause to be enlarged to the size required for the pin or
hook, and made truly round by an ordinary drilling or rimering process, which not
only makes the hole of the requisite size, but also leaves its circumference or "lip"
fairly sharp in the edge. The knob is then ready for fixing.
I next prepare the pin or hook to receive this knob, and will take, for example,
a knitting pin, the process of applying the metal knob being substantially the same
in all cases. To do this, if the material of which the pin is made be a hard and
rigid one, I cut around and near the end upon which the knob is to be fixed, a
small groove as shown at A. in Fig. 1., B denoting the top of the pin, and this I do
by any of the ordinary and well known means of cutting such grooves. The pin
being thus prepared, I pass the top of it upon which the groove is cut, vertically
through a hole in a die which is fixed in the bed of a press, this hole having around
:

page_text: up
its upper part a saucer-like countersinking, and the top of the pin stands in the
centre of this countersinking so as to leave the groove just clear to sight, and in
this position the workman holds or fixes it below.
Directly above the top of the pin thus placed, the press is provided with a
punch, the face of which also has in it a holiow corresponding in concavity to the
saucer-like hollow in the die; and this punch is raised or lowered by the usual
screw action common to presses.
Upon the top of the kuitting pin, I then by means of the hole in its underneath,
place one of the hollow globe-shaped knobs, before described, and the stage,
so far, of the operation will be understood by referring to section Fig. 2
wherein B represents the top of the pin, and C the hollow globe shaped kuob placed
upon it, D. D denoting the saucer-like hollow in the die E. E. and F the nose of
the punch raised or lowered by the screw action of the press in which it is fixed.
The pin having been thus placed in position and the hollow globe shaped knob
also put upon the end prepared to receive it, I then, by a turn of the press haudle
bring down the hollowed face of the punch F upon the top of the knob C, and the
pressure of this punch forces the knob down into the saucer-like opening D. D in
the die E. E. and changes the globular shape of the knob into that of an oblate
spheroid as shown at C in section Fig. 3, (in which fig. the same letters of reference
denote the same parts) and at the same time forces the "lip" of the hole in the
underneath part of the hollow knob into the small groove before mentioned, in the
end of the pin. The knob is then firmly fixed in its place.
Or, I may in certain cases, where the material of the pin is not of a hard and
rigid nature, dispense with the first cutting of the small groove therein, since in a
more yielding material the compression, of the hollow globe shaped knob by the
action of the press into that of an oblate spheroid, causes the "lip" of the hole in
the knob to cut its own groove and fall into and occupy it with the same result.
And in the foregoing statement I have mentioned no means of performing
operations otherwise than by those which as mechanical appliances are known to
any working mechanic, and therefore call for no further description.
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 :
The above described method of attaching knobs or handles to knitting pins,
tricot, and crotchet hooks by causing these knobs or handles, made of metal, to fit
into a groove either previously cut for them or formed by the knob or handle
itself, by the means and in the manner substantially as above set forth.
