I JOHN NORTHWOOD of Kingswinford in the County of Stafford Art Director
Glass Works Brierley Hill do hereby declare the nature of my invention for
DECORATING IN VARIOUS DESIGNS THREADED GLASS ARTICLES IN COURSE OF
MANUFACTURE to be as follows:-
This invention relates to apparatus for use by Glassmakers in decorating Glass
articles, in concerted patterns by threading such threads being of the same or of
different color or colors to the article, Hitherto these threads were pulled with a
hook or pushed with a knife used by the hand only pulling or pushing one part or
division of the threads at one time which gives them a festoon shape by this
method the divisions are inaccurate and the work occupies considerable time.
The especial objects of this Invention are to supersede the primitive method and
to combine the pulling and pushing actions in one apparatus so as to pull or push
at one time any number of accurate divisions on the articles that are required.
In carrying this Invention into practice I proceed to make a cylinder of Wood,
Brass, Iron, or any suitable substance and of any size required, The same cylinder
being divided into two or more parts and hinged so as to allow a threaded cylin-
erical piece of pliable Glass to be inserted and withdrawn. In the cylinder are
fixed a number of toothed blades equi-distant from each other, between each of
these fixed blades slots are formed in the cylinder into which are inserted toothed
blades of greater length than the fixed ones, and which will slide up or down
according to the pattern required, The teeth on all these blades are somewhat
similar to those of an ordinary saw. The workman having a cylinderical piece of
metal threaded with the color required on the end of his blowpipe and heated until
pliable places it into the machine above described which is then closed, he now
blows down the blowpipe thereby expanding the metal so that the projecting teeth
or points of the blades bind or hold the threads.
The moveable blades being longer than the cylinder are made to project at
bottom so that the machine now stands on them, the cylinder is pushed down the
longer blades which hold fast the threads where they bind while those fixed to.
the cylinder pull down with them the parts which they bind; thereby forming a
pattern according to the adjustment of the said blades..
The article is then taken out of the machine and fashioned into shape required
in the usual way.

I JOHN NORTHWOOD of Kingswinford in the County of Stafford Art Director
Glass Works Brierley Hill do hereby declare the nature of my invention for
DECORATING IN VARIOUS DESIGNS THREADED GLASS ARTICLES IN COURSE OF
MANUFACTURE 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 apparatus for use by Glassmakers in decorating Glass
articles in concerted patterns by threading, such threads being of the same or of
different color or colors to the article; Hitherto these threads were pulled with a
hook or pushed with a knife used by the hand only pulling or pushing one part or
division of the threads at one time, which gives them a festoon shape, by this
method the divisions are inaccurate and the work occupies considerable time.
The especial objects of this invention are to supersede the primitive method and
to combine the pulling and pushing actions in one apparatus; so as to pull or push
at one time any number of accurate divisions on the articles that are required. In
carrying this Invention into practice; I proceed to make a cylinder of Wood Brass,
Iron, or any suitable substance and of any size required. The same cylinder being
divided into two or more parts and hinged so as to allow a threaded cylindrical
piece of pliable glass to be inserted and withdrawn. In the Cylinder are fixed a
number of toothed blades equidistant from each other between each of these fixed
blades slots are formed in the cylinder into which are inserted toothed blades of
greater length than the fixed ones, and which will slide up or down according to
the pattern required; the teeth on all these blades are somewhat similar to those of
an ordinary saw. The workman having a cylindrical piece of metal threaded with
the color required on the end of his blowpipe and heated until pliable places it
into the machine above described which is then closed, he now blows down the
Blowpipe thereby expanding the metal so that the projecting teeth or points of
the blades bind or hold the threads.
The moveable blades being longer than the cylinder are made to project at
bottom so that the machine now stands on them the cylinder is pushed down the
longer blades which hold fast the threads where they bind while those fixed to
the cylinder pull down with them the parts which they bind thereby forming a
pattern according to the adjustment of the said blades.
The article is then taken out of the machine and fashioned into shape required
in the usual way.
Or what I prefer is the cylinder fixed upon a bed of Iron wood or any suitable
material Fig. 1 I and with a hole in centre rather larger than interior circle of
cylinder A (as seen in Fig. 3 B) so as to admit of the cylinder A being opened (by
loosening the catch L on handles M M) when the moveable blades H project at
bottom as in Fig. 1 this said hole having a cover of sheet Iron fast to the bed and
under the cylinder containing spaces to admit of the moveable blades H travelling
through see Fig. 2 G and Fig. 4 G. underneath the bed I is attached a cross-bar as

page_text: seen on Fig. 1 & Fig. 3 C through which travels a screw D having on its lower
end a fixed hand wheel F on the upper end of this screw is attached a disc E which
is forced up and down the guides K by the action of the wheel and screw, the
metal of the required size is then threaded as Fig. 5 and placed in machine as
Fig. 3 and resting upon the cover G the mould is then closed and fastened by
means of handles M and catch L. The workman now blows down the Blowpipe N
thereby expanding the metal and fastening the threads in teeth of Blades as before
described the hand wheel is then quickly turned forcing the disc E and moveable
blades H up the cylinder taking with them the threads held by the moveable
blades and converting the threads into a pattern as shewn in Fig. 6.
Having how particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
A method of pulling or pushing any number of divisions of Glass threads on
Glass at one and the same time by the action of toothed Blades which may be
fitted by slots or guides to a mould or cylinder with a free action to move up or
down.
