JOHN NORTHWOOD of Kingswinford, in the County of Stafford, Art Directer,
Glass Works, Brierley Hill do hereby declare the nature of my invention for
IMPROVED STAMP AND OTHER APPLIANCES FOR DECORATING GLASS WITH VARIOUS
DESIGNS IN RELIEF, to be as follows:-
This Invention relates to machines or apparatus used by Glassmakers and
technically known as prunts used in decorating Vases, Bowls, and other Glass
articles, these prunts being usually made of Brass, Iron or any other suitable metal,
and into which the pattern is sunk or cut, a piece of Molten Glass being stuck to
the vase or other object the prunt or die is pressed upon it, leaving the design or
pattern imprinted upon its surface.
The special object of this Invention is the production of a greater variety of
Designs: together with a greater sharpness of outline, and also enables them to
stand out froin the vases or other articles in high or low relief as desired this being
impractical with the common prunt or die in use.
In carrying this Invention into practice I construct a stamp or hand press by
making a casing or mould of suitable metal or other material, of the shape I require
the outside of flower, leuf, rosette, or other decorations to be, and which acts as a
guide to a die working inside the said casing or mould up or down. I also make a
pair of pincers or guides which open similar to those generally used in the trade the
ends being flattened at right angles, to the blades a half circle is then cut or filed
out of the inner edge of each flattened part; so that when the edges are pressed
or closed, together they form a round hole or circle, any other shaped hole being
made if required.
To use the machine suppose the vase or article to be made and ready for
decorating the pincers are held on the vase, so that the shaped hole is over the
part I.wish to put the flower or ornament upon. I then stick a piece of Molten
Glass through the hole, on to the body of vase then placing the stamp or mould
over it & pressing the die downwards, thereby making the impression of die and
mould upon the piece of molten Glass.

JOHN NORTHWOOD, of Kingswinford in the County of Stafford Art Director
Glass Works Brierley Hill do hereby declare the nature of my invention for
IMPROVED STAMP AND OTHER APPLIANCES FOR DECORATING GLASS WITH VARIOUS
DESIGNS IN RELIEF 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 machines or appratus used by Glassmakers and
technically known as prunts used in decorating Vases Bowls and other Glass
articles these prunts being usually made of Brass Iron or any other suitable metal
and into which the pattern is sunk or cut, a piece of molten Glass being stuck to
the vase or other object, the prunt or die is pressed upon it leaving the.design or
pattern imprinted upon its surface.
The special object of this Invention is the production of a greater variety of
Designs together with a greater sharpness of outline and also onables them to
stand out from the vases or other articles in high or low relief as desired, this being
impractical with the common prunt or die in use.
In carrying this Invention into pratico I construct a stamp or handpress by
making a casing or mould of suitable metal or other material of the shape I require
the outer edge of flower, leaf, rosette or other decorations to be, and which acts as
a guide to a die working inside the said casing or mould up or down. I also make
a pair of pincers or guides which open similar to those generally used in the trade,
the ends being flattened at right angles to the blades; a half circle is then cut or
filed out of the inner edge of cach flattened part, so that when the edges are pressed
or closed together they form a round hole or circle; any other shaped hole may be
made if required.
To use the machines, suppose the vase or article to be made and ready for
decorating; the workman has a piece of metal stuck to the Bowl and cut off the
required size see Fig. 6 V he then takes the stop pincers and clips the piece of metal
near the Bowl with them as in Fig. 6 the servitor or attendant then places the
stamp down on the stops and over the metal pressing down the die which forcos
the metal to take the impression of dio and mould, the stamp and stop pincers are
then removed leaving a flower raised off the body of Bowl or Vase as in Fig. 7 & 8.
Fig. 1 A is the casing or mould, the inside being shaped as in plan Fig. 2 fitted to
travel up and down, this casing or mould is the die H as seen in Fig. 3 this being
fastened to tube C which also travels through fitting B, a slot is cut in tube C,
Fig. 1 F passing through this slot and fast to B is a set screw E acting as a guide
to tube and die and a support to spring G. Fixed in top of tube C is a handle D
for pressing the die EL down casing or mould this being carried back into original
position by spring G when pressure is removed Fig. 5 represents the stop pincers,
KK the blades or springs M M the supports or stops. Fig. 9 is a combination of
the stop pincers and stamp previously described, on the spring end of stop pincers
is fastened or welded a piece of steel, or other material, see Fig. 9 R to this is

page_text: fastened by pins S S two spring arms O & P, O carrying the die H, & P carrying
the casing or mould A, about 4 inches from end of O is screwed a pin T which
binds upon P for regulating the pressure of springs; the die H is fastened to arm o
by means of pin and nut Ċ C this die being fitted so as to slide or travel up and
down the mould A, which mould is fastened to arm P by forks and pins N N.
To use this machine the metal is stuck on the Bowl or Vase and caught between
stops of pincers as before explained by passing the spring arm 0 the die H and
mould A are forced down upon the stops M M and metal, which metal takes the
impression of die and mould the pressure is then taken off arm O which causes the
die and mould to fly back instantly into their original position, the stop pincers are
also allowed to open and the whole apparatus removed leaving a flower same as
made by using stop pincers and stamp separate.
Having now 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
The use of a hand mould to give shape to edge of flowers leaves or other
decorations on Glass articles into which slides a die for giving an impression and
for pressing the molten glass to the shape of the mould either with the stop pincers
under as described, or without them; in the latter case the flower or ornament is
pressed on to the article.
I also claim the use of what I have described as and called stop pincers either in
conjunction with the stamp or if used with an ordinary prunt or other die.
