Improvements in Apparatus for Boiling or Agitating Water in
Coppers and other Vessels.
I, SAMUEL JOSEPH MACKIE of 27 Chancery Lane, in the County of
Middlesex Civil Engineer do hereby declare the nature of this invention to be as
follows:-
Steam is commonly used in factories wash-houses and otherwise for boiling water
by means of coils, jackets and open pipes. In order to avoid the formation of
geysers and spurts as well as the noise and other inconveniences caused by the
issue of steam from an open pipe delivering direct into the water to be boiled: as
also for the simpler and more inexpensive means of effecting the boiling, I employ
a disc of metal or other suitable material perforated with a number of holes Fig. 6
and preferably furnished with a turned over rim projecting downwards along the
extent of its periphery. The numerous perforations are preferably radially disposed
and also preferably the dimensions of the perforations are increased from around
the centre to near the outer edge of the disc. The steam is supplied to the disc by
a steam pipe of any suitable size and issues from orifices radially drilled or other-
wise formed in the plug which closes the end of the steam pipe, see Sheet 1.

some of the steam, its passage being impeded by the rim of the disc b¹², ascends
through the perforations o, 0, 0, 0, 0, so that the water above the disc as well as
below it is simultaneously and uniformly raised in temperature to the boiling point

particularly serviceable for all such automatic washing apparatus and to other
purposes described in Susan Arabella Mackie's second Patent No. 13903 1890.
It is also adapted for open washing tubs and any sort of laundry appliances.

at all.
The discs may also be used single or two or more conjoined may be
employed with or without perforations and with or without rims. Slots may be

COMPLETE SPECIFICATION.
Improvements in Apparatus for Boiling or Agitating Water in
Coppers and other Vessels.
I, SAMUEL JOSEPH MACKIE of 27 Chancery Lane in the County of Middlesex
Civil Engineer 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 :-
Steam is commonly used in factories, wash-houses and otherwise for boiling water
by means of coils, jackets and open pipes. In order to avoid the formation of
geysers and spurts as well as the noise and other inconveniences caused by the
issue of steam from an open pipe delivering direct into the water to be boiled: as
also for the simpler and more inexpensive means of effecting the boiling I employ a
disc of metal or other suitable material perforated with a number of holes Fig. 6
and preferably furnished with a turned over rim projecting downwards along the
extent of its periphery. The numerous perforations are preferably radially
disposed and also preferably the dimensions of the perforations are increased from
around the centre to near the outer edge of the disc. The steam is supplied to the
disc by a steam-pipe of any suitable size and issues from orifices radially
drilled or otherwise formed in the plug which closes the end of the steam-pipe
(see Sheet 1). The drawing Sheet 2. shows in section an automatic washer after
the construction described in the Patent of Susan Arabella Mackie No. 5917
1890 fitted with one of my steam boiling discs. A. is a wooden vat in the
place of the ordinary copper or galvanized iron boiler. The washer patented in
No. 5917 1890 is shown as B. with the orifices for the jets j, j &c. and the funnel F
and steam-ring R. The water-filled interspace between the outer and inner vessels
is marked T. My steam boiling disc D is placed under the funnel F of the
washer B and the rim of the disc is marked 62. P is the plug to the top of
which the disc is secured. This plug is hollowed out internally nearly to the top
forming the cavity C. The head of the plug H projects all round the shank of the
plug so that when it is passed through the hole made in the bottom of the wooden
tub or any other outer vessel a good water-tight joint can be made by nutting up
the screwed end by the nut N. After this a T-pipe X is screwed on and then the
discharge tap E for letting out the dirty water after washing or for rinsing or
other purposes.
The steam is controlled by a cock put up externally at some
convenient place. The steam admitted at X rushes up the cavity and issues
through the radial holes p. p. in the plug P. As it mingles with the water in the
interspace below the washer and under the disc D some of the steam, its passage
being impeded by the rim of the disc b 2 ascends through the perforations o o000,
so that the water above the disc as well as below it is simultaneously and uniformly
raised in temperature to the boiling point and a continuous circulation of the
washing water is effected. My invention is particularly serviceable for all such
automatic washing apparatus and to other purposes described in Susan Arabella
Mackie's second Patent No. 13903 1890. It is also adapted for open
washing tubs and any sort of laundry appliances. If it be desired to use my
invention for agitating or circulating purposes in water or other fluids at
temperatures at or below the boiling point steam or air or gases compressed or
heated can be supplied for the purpose. The steam discs may also be made hollow
with perforations above or below or along the rims or without perforations at all:
or they may be made conical in form. The discs may be used single or two or more

page_text: conjoined may be employed with or without perforations and with or without rims.
Slots may be used instead of circular holes or perforations. Plates of rect-
angular or other forms, single or double, with or without rims and perforate or
imperforate and employed singly or as multiples to suit the work to be done can be
used as shown in Figs. 3, 4, and 5.
Of the drawings Sheets 1 and 2 were lodged with the Provisional Specification
and now form part of the Complete Specification with Sheet 3.

The invention will be understood by reference to the annexed drawings:
Sheet I shows the steam boiling-disc D consisting of a flat piece of m·tal with
The enlarged
turned-over rim 12 and a number of perforations o 0 0 0
portion in the central part or plug P has an overlapping head shown at H: and
the radial perforations in it p p are for the admission of steam from the steam-
pipe s. c. into the vat or boiler A. The cavity in the plug P is shown at C: and
the nut N is for tightening up the joint between the head H and the steam and
discharge apparatus under the vat or boiler A.
Sheet II shows a cylindrical wooden vat A or boiler with the washer B (as in
Patent 5917 1890) in it and with the steam boiling disc D and the sluicing
apparatus Z attached to the vat A complete for working. T T indicate the inter-
mediate space between the outer or boiling vat A and the inner vessel or washer B.
RR is the steam-ring: F the funnel and J. J the jet-holes. E is the sluice cock :
K the handle for opening and shutting it. The discharge-pipe from the vat or
boiler is shown at Z.
Sheet III shows the like arrangement of the steam boiling-disc D, and the
sluicing cock and pipe Z: but in combination with a splayed wooden or earthenware
vat A to which is further attached an inner ring or ledge L L for the flange of
the cylindrical, or other washer B to rest upon and in this way on any boiling over
from the interspace T the water runs back into the washer B instead of down the
outside of the vat A. A second ring (r) is employed preferably with the
washer, B.
The letters employed in the descriptions indicate the same parts in all the
drawings.
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 :-
(1.) The perforated steam-boiling disc with turned-over rim and radially
chambered plug or head.
The several modifications of the same.
(3.) The apparatus for supplying steam to the disc and discharging water from
the boiler or agitating vat.
(4.) The splayed wooden or earthenware vat in connection with the above.
(5.) The particular combination of the steam boiling disc, the steam inlet and
water discharging apparatus with the cylindrical or the splayed wooden or earthen-
ware vat and of the same with other automatic washing apparatus similar to that
described and shown in the aforesaid Specifications.
All substantially as herein described and illustrated.
(6.) The use of hot or compressed air or gases in the place of or in conjunction
with steam for boiling or agitating of fluids in combination with the disc
described.
