I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in what
nanner the same is to be performed, to be particularly described and ascertained
n and by the following statement :-
This invention relates to an improved compressing apparatus by means of which
iquids of any kind may be put under pressure in order to enable them to be
projected, raised or distributed in any desired manner.
Of
In order to make the invention better understood apparatus according to the
present invention is illustrated by way of example, in the accompanying drawing.
course the constructions and applications may vary very much without departing
from the spirit of this invention.
In this drawing Fig. 1 shows a compressor according to the present invention in
section with the outlet for the liquid at the side.
Fig. 2 is a modified construction showing the outlet for the liquid at the top of
the apparatus.
The apparatus is constituted by a reservoir A for the liquid in which is arranged a
tube B constituting a pump chamber or barrel and provided for this purpose with
a very light valve C, that is to say the density of the valve is preferably only slightly
In this tube B is a tubular plunger D provided
greater than that of the liquid used.
at its base with a valve E opening in the same direction as the valve Ci.e. upwards.
This plunger, which forms the piston in the tube B is surmounted by a bell or
receptacle H of any desired form and dimensions the interior of which communicates
with the interior of the tubular plunger D.
Finally the bell or receptacle H is provided with a discharge branch G the outlet
5 of which shaped according to the use for which the apparatus is intended. A re
movable nozzle F at the outer end of the branch G enables the discharge jet to be
modified.
The working of the apparatus will now be easily understood.
The reservoir A having been previously filled with liquid, the plunger Di
30 reciprocated the effect of which is to cause a quantity of liquid to pass at eac
It follows that the air in said bell o
stroke into the bell or receptacle H.
receptacle will be compressed by the incoming liquid and its volume reduced a
each stroke. In other words, at each stroke the bell will be supplied with liqui
which compresses the air and reduces its volume.

The liquid being thus under pressure it is only necessary to open the cock G
cause the compressed air to force out the liquid from the receptacle with a for
depending on its pressure.
When, for any reason, it is desirable to arrange the discharge above the lev
of the liquid, the arrangement shown in Fig. 2 may be adopted which consis

plunger D.
As before stated the apparatus may be used for various purposes such as for
instance for toilet atomisers inhaling or injecting apparatus of all kinds illuminating
apparatus by means of a jet of petroleum or other combustible liquid etc.
Having now párticularly described and ascertained the nature of this invention
as communicated to me by my foreign correspondent and in what manner
same is to be performed I declare that what I claim is :-
the
1. Apparatus for spraying or delivering liquids by means of compressed air
comprising a liquid receptacle provided with a tubular pump barrel and a tubular
piston having a bell or receptacle mounted at its upper end whereby
a compression of the air contained in the bell is obtained by forcing the
liquid into the bell by means of the piston the expansion of said air being afterwards
utilised for projecting the liquid.
2. The combination and arrangement of parts constituting the complete apparatus
for spraying or delivering liquids substantially as described or illustrated in the
accompanying drawings.
