PROVISIONAL SPECIFICATION left by the said William Edward Gedge at
the Office of the Commissioners of Patents on the 26th April 1882.
WILLIAM EDWARD GEDGE, of No. 11 Wellington Street Strand London in the
County of Middlesex Patent Agent "AN IMPROVED PRESS FOR MOULDING
SEGGARS OF ALL SHAPES AND SIZES, APPLICABLE ALSO TO THE MOULDING OF
OTHER CERAMIC WARE" A communication from abroad by Auguste Pothier, of
Paris, France, Engineer,
This invention relates to a Machine for moulding Seggars applicable to the
moulding of a great variety of ceramic ware, such for example as pipes, pottery
for chimneys, tube ferules for earthen ware stoves, gas retorts, glassmaker's crucibles,
bricks for arched roofs or vaults, ceramic tiles, sockles, pedestals or plinths for
statues, vases and other articles.
The mould also permits obtaining round, square, oval or other shaped Seggars, it
only being necessary for that purpose to give to the several parts composing the
mould the required round square oval or other shape
This invention may be considered as composed of two distinct combinations
which I will name, the first the "three Screw Press," the second the "Seggar-
mould"
The Press is composed of a frame planed at its upper part and carrying two
bosses or enlargements, through which pass horizontal screws, and four lugs which
serve to support four iron columns secured to the frame by strong nuts.
These columns are turned throughout, screw threaded at their ends, and parallelly
placed with great care. In the centre of the upper surface of the frame there is a
rectangular opening the utility of which will be hereinafter explained.

page_text: A plate unites the columns at the upper part and has in its central part a
threaded nut in which a very strong screw inay rise and fall but without turning
on itself, this screw having a moveable plate securely fixed to its lower end.
Nuts set in the bosses or enlargements of the frame may turn round their
common axle. They are traversed by horizontal screws placed very exactly on
the same axle and at the same beight-Two spur wheels are keyed on the said
nuts and a spur wheel is also keyed on the nut of the vertical screw.

enlargements of the frame.

Two supports fitted to the frame and two others fixed to the ground carry
horizontal shafts upon each of which are set three pulleys furnished with their
respective bars for disengaging.
A vertical shaft passes through the aforesaid fixed plate uniting the columns at
their upper part and upon this shaft is keyed a pinion gearing with the wheel
keyed on the nut of the vertical screw, and a bevel wheel gearing with a bevel
pinion keyed on one of the horizontal shafts.
The aforesaid fixed plate uniting the columns at their upper part supports a
-double armed lever_the_larger arm of which passes through one of the disengaging
bars, its-smaller arm passing through. a vertical bar which serves to actuate
automatically the said disengaging bar. The vertical bar is supported at its lower
part in a bearing and at the top by the said fixed plate.
A bar keyed on an axle having a support fixed on the ground serves to actuato
automatically the other disengaging bar. In this axle bearing slides a bar receiving
its movement from a washer-fixed-at-the-end-of-one of the horizontal screws
The seggar mould is composed of a case of cast or of wrought iron and with
every interior made true; of a cast iron piston bolted to the moveable plate of the
Press; of a piece fixed to the said moveable plate and serving to keep the piston
from sliding thereon, and of two other pistons securely fixed to the horizontal-
screws of the press
A table in two pieces, attached to each other, carries a rod which passes by the
hole in the middle of the frame. This table carries slide bars for the pistons
attached to the horizontal screws of the press. A plate with rack set in the centre
of the table forms the bottom of the mould and may be lifted by means of a pinion
keyed on a shaft in connection with a socket koy carrying a lever. Rods fixed in
the case serve to lift it by the aid of the aforesaid moveable plate.
Iron bars turning around the rods in the case serve to secure this latter to the
table which carries bolted columns upon which rest a fixed bar.
Finally columns fixed upon the table are intended to secure the bars turning
around the rods in the case.
To complete the description of the mould it is only necessary to add that round,
square or any shaped Seggars are obtained at pleasure by giving corresponding
forms to the various pieces composing the mould

OTHER CERAMIC WARE A communication from abroad by Anguste Pothier of
Paris, France Engineer
This invention relates to a machine for moulding Seggars applicable to tho
moulding of a great variety of ceramic ware, such for example as pipes, pottery
for chimneys, tube ferrules for earthenware stoves, gas rotorts, glassinaker's
crucibles, bricks for arched roofs or vaults, ceramic tiles, sockles, pedestals or
plinths for statues, vases and other articles.
The mould also permits obtaining round, square, oval or other shaped Seggars, it
only being necessary for that purpose to give to the several parts composing the
mould, the required round, square, oval or other shape.
On the accompanying Sheet of Drawing:-
Figure 1, represents the improved machine the subject of this invention in
Elevation and in Section.
'
Figure 2, showing the same in side view and in section and
Figure 3, being a plan and horizontal section thereof.
Similar letters indicating similar parts in each of the Figures respectively :-
This invention may be considered as composed of two distinct combinations
which I will name, the first, the "three screw press," the second, the "Seggar
mould."
The Press is composed of a frame A, planed at its upper part and carrying two
bosses or enlargements through which pass horizontal screws, and four lugs
which serve to support four iron columns B, B1, B2, B³, secured to the frame by
strong nuts.
These columns are turned throughout, screw threaded at their ends, and parallelly
placed with great care. In the centre of the upper surface of the frame there is a
rectangular opening, the utility of which will be hereinafter explained.
A plate C, unites the columns at the upper part and has in its central part a
threaded nut D, in which a very strong screw E, may move up and down, but
without turning on itself.
A moveable plate F, is securely fixed to the lower end of the screw E.
The nuts G, G¹, set in the bosses or enlargements of the frame A, may turn
round their common axle. They are traversed by horizontal screws H, H₁, placod
very exactly on the same axle and at the same height. Spur wheels 1, 1', are
keyed on the nuts G, G', and a spur wheel J, is also keyed on the nuts of the
vertical screw E.
The shaft K, passing longitudinally through the frame A, carries two pinnions
gearing with the toothed wheels I, I¹; it is itself supported by the frame A.
The supports L L fitted to the frame A, and the supports M, M', fixed to the
ground, carry horizontal shafts N, N¹, upon which are set the pulleys 0, 0¹, 0",
and 01, 02, 03, furnished with their respective disengaging bars P and P'.
The vertical shaft Q, passes through the fixed plate C, and upon this shaft are
keyed the pinion R, gearing with the wheel J, and the bevel wheel S, gearing with
the bevel pinion T, which is keyed on the horizontal shaft N'.
A bent lever U, is carried by the fixed plate C; its larger arm passes through
the disengaging bar P¹ and its smaller arm passes through the vertical bar V,
