page_text: I, ALFRED JULIUS BOULT, of 323 High Holborn, in the County of Middlesex,
Engineer, do hereby declare the nature of the said invention (a communication
from Charles William Dennis, of the City of Toronto, Canada, Merchant), and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The invention relates to that class of washing machines commonly known as
washing-fountains by which a circulation is caused within a boiler containing dirty
clothes; and the object of the invention is to so construct a washing-fountain
that a more powerful and constant circulation may be insured; and it consists
essentially in placing two or more domes or air vessels on the irregular passage
ways formed in the hollow base constituting the circulator, from which circulator
the water is caused to ascend by the pressure produced within the dome or air
vessel, substantially as hereinafter specified.
Figure 1, is an outside view of my improved wash boiler fountain.
Figure 2, is a view of the bottom of the base forming the fountain.
The base, A, is hollow and made of material which will not rust. This base, A, is
closed on its top, but its bottom has zig zag or alternately right and left spiral
passages, B, C, and D, alternately swelled and contracted, as indicated in the
drawing. The passage, B, leads from the outer periphery of the base, A, to the
bridge, a. The passage, C, leads from one side of this bridge around the circum-
ference of the hollow base, A, to the other side of the bridge, a, and the passage, D,
leads from, C, to the centre chamber, E, from which centre chamber, E, the pipe or
fountain F, leads. An air vessel or dome, G, is placed on the passage-way B,
near its opening and a similar dome or air vessel, H, is placed at the end of the
chamber, E, near the partition or bridge, a. The effect of these two air vessels is
that the water as it enters the passage-way, B, is forced around the zig zag
passage-ways, B, C, and D, till it reaches the inner chamber, E, when in coming in
contact with the end of the chamber, E, it is caused to rebound by the expansive
force of the air within the air vessel, H, consequently the force produced by the air
chamber, G, is acted against by the force produced by the air vessel H, and in that

pipe, E, and thus a powerfully moving circulation is maintained within the wash-
boiler and the clothes by the action of the circulation are thoroughly cleansed.
I do not claim broadly a wash-boiler fountain.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed I declare that what I claim is
1. A wash boiler fountain having a hollow base, A, with the passage-ways, B, C,
and D, arranged in it as specified, and a chamber, E, from which the fountain F,
extends, in combination with an air vessel, G, placed near the entrance of the
passage-way, B, and an air vessel, H, placed at or near the end of the inner
chamber, E, substantially as and for the purpose specified.
