PROVISIONAL SPECIFICATION.
Improvements in Machines for and Method of Making "Saggars"
and the like.
I, BENJAMIN ROBINSON, of Church Gresley, in the County of Derby, Sanitary
Ware Manufacturer, do hereby declare the nature of this invention to be as
follows:-
:—
Saggars are receptacles in which articles such as lavatories closets and the
like are placed for firing in the kiln and have hitherto been generally built up by
hand or formed by other more or less laborious processes; the object of my
invention is to make them in greater part by machinery.
In carrying out my invention I employ a machine which in principle is very
much like the ordinary sanitary pipe machine in which a worm feeds the clay
down through a die, the latter however will vary in form transversely according
to the cross section of the saggar to be produced.
A vertically movable platform is employed in the usual way carried on a rod
engaging a crank at its lower end. Upon this is preferably placed a plate similar
to that used in carrying sanitary pipes upon and on this a "batt
66
or slab of
clay (preferably formed in another machine) is placed; the lower edge of the
die is formed with sharp depending cutting edges and by means of a lever the
platform and "batt" of clay are raised up thereto, the latter being thus neatly
cut off to the form of cross section of the saggar" to which it constitutes the
bottom; the clay is fed downwards until it comes into contact and unites with
the "batt" of clay on the plate, the crank is now turned and the platform.
descends, the body of the saggar being thus made and cut off to any desired
length.
Air is admitted to the inside of the "saggar" or the like at any desired points
as it is being formed and as may be found most expedient.
Dated this 9th day of October 1899.

page_text: Ware Manufacturer, 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:-
Saggars are receptacles in which articles such as lavatories, closets and the
like are placed for firing in the kiln and have hitherto been generally built up by
hand or formed by other more or less laborious processes; the object of my
invention is to make them in greater part by machinery.
In describing my said invention reference will be had to the accompanying
sheet of drawings upon which:
Figure 1 is a vertical section through my improved machine or apparatus on
line a, a of Figure 2.
Figure 2 is a horizontal section on line b, 6 of Figure 1.
Figure 3 is a vertical section on line c, c of Figure 4 shewing my invention as
arranged for making the "batts" to be hereinafter explained.
Figure 4 is a horizontal section on line d, d of Figure 3.
In carrying out my invention I employ a machine which in principle is very
much like the ordinary sanitary pipe machine, in which a worm feeds the clay
lown through a die; the latter however will vary in form transversely according
to the cross section of the saggar to be produced.
The worm and casing being well known in sanitary pipe machines and readily
understood are not shewn upon the drawings, but would of course be above the
die.
A vertically movable platform A is employed (as is usual in machines for
making sanitary pipes) carried on a rod B engaging a crank at its lower end
(not shewn upon the drawings).. Upon this is preferably placed a plate C similar
to that used in carrying sanitary pipes upon, and on this, a "batt" or slab of
clay is placed at D): the lower edge of the die is formed with sharp depending
cutting edges E and by means of a lever the platform A and "batt" of clay D
are raised up thereto, the latter being thus neatly cut off by the cutting edges E
to the form of cross section of the "6
saggar" to which it constitutes the bottom;
the clay is fed downwards until it comes into contact and unites with the "batt"
of clay on the plate; the crank is now turned and the platform descends, as shewn
by dotted lines on Figure 1, the distance however being made to vary according
to the depth of saggar required, the body of the saggar being thus made and
cut off to any desired length.
Air is admitted to the inside of the "saggar" or the like at F, F, or any other
desired points as it is being formed and as may be found most expedient, the
tubes Falso serving the purpose of adjusting the centre K to its proper position.
I also employ the same mouthpiece G for making the "batts" above referred
io. The centre K and bottoni flange H, which constitute the die, are removed
and in place of these I fix another plate L having a slot L¹ therein as shewn on
Figures 3 and 4, the clay is fed through the die in the same way as before and
the "batt" is produced and carried away on the board shewn by dotted lines on
Figure 3, this board being held up in position to the die plate L by any suitable
means.
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:-
1. In a machine for making “saggars " and the like the combination of a
vertically feeding clay machine having a movable platform, with die having
adjustable centre K, solid under plate and space between it and platform in which
the bottom of the saggar is formed, trimming device E and enclosing flange H
substantially as described and illustrated.
2. The means and method of forming "batts" of clay in the same machine
substantially as described and illustrated.

feeding clay machine substantially as described and illustrated.
