COMPLETE SPECIFICATION.
Improvements in the Filling Nozzles of Hot Water Bags, Cushions,
Beds, and the like.
I, WILLIAM CURRIE, of the firm of William Currie & Co., Caledonian Rubber
Works, in the City of Edinburgh, 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 :-
This invention which relates to the nozzles or tubes fitted into hot water bags,
cushions, beds, pillows and the like for the purpose of filling and emptying them
has for its object to so construct the nozzle or tube that in addition to the ordinary
central passage through which the water is poured there is provided one or more
additional passages or vents for the escape of the air inside the vessel. With the
usual construction the air is in the act of filling expelled through the same passage
as that through which the hot water is being poured in so causing bubbling or
spluttering of the water whereby the hands of the person filling the vessel are
liable to be scalded.
The
The improved nozzle or tube is illustrated under two modifications in vertical
section at Figures 1 and 3 and in plan of the top or outer end at Figures 2 and 4
of the annexed drawings and as shewn by these figures in addition to the usual
passage a through which the water is poured in and out a series of vents or
passages are made exterior to and parallel with the passage a the air or a portion
of it expelled in the act of filling the vessel passing out through these vents.
passages a and b are, when the vessel has been filled, closed by a plug e screwed into
the neck a¹ of the nozzle or they may be closed by a cap screwed on to the exterior
of the neck a leather, india rubber or other elastic washer d being preferably
inserted between the metal of the plug or cap and of the nozzle to render the joint
water tight.
The air vents or passages 6 may be formed in the wall of the nozzle the metal
being of sufficient thickness to enable that to be done and as shewn at Figure 3
they may extend the full length of the nozzle or they may be terminated at the
bottom of the neck as at Figure 1.
Under a modification instead of making the air vents in the thickness of the
metal a separate and exterior tube having an annular space between it and the
exterior of the nozzle may be employed the said tube being held in position by
strips or tongues inserted at intervals vertically in the annular space. This
exterior tube may be the full length of the nozzle or of shorter length in which
latter case slits are made in the wall of the nozzle at or near the bottom of the tube
to permit of the outward passage of the air into the annular space.
With any of these modifications the vessel can be more completely filled with
water and in less time than with a nozzle of ordinary construction.
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 :-
In a filling nozzle for hot water bags cushions beds and the like the provision in
addition to the ordinary central passage of one or more vents or passages,
substantially as and for the purpose set forth with reference to the drawings
annexed.
