PROVISIONAL SPECIFICATION.
Improvements in Caps or Covers for Chemical Fire Extinguishers
and other Vessels.
I, JAMES HASLAM of 229 Bury Road, Tonge near Bolton in the County of
Lancaster, Chemical Fire Engine Manufacturer and Tin Plate Worker, do hereby
declare the nature of my said invention to be as follows:-
-
My invention relates to improvements in nozzles for chemical fire extinguishers and
other vessels, such as, metallic and other bottles, closed cisterns or tanks, liquid
carts, and others and consists in providing ready and efficient means for either filling
or emptying the same.
In carrying out my invention I provide a nozzle with a hinged cap or cover; the
latter being provided with a cavity to receive an india-rubber or other joint ring
secured in any convenient manner to form a tight joint when closed over the inlet
of the nozzle. When the hinged cap or cover is placed over the nozzle it is secured
in position by a swivelling handle or its equivalent provided with a lip which slides
under a bayonet or other projection on the outside of the nozzle.
This invention, or part of it, may be applied to existing bottles and other vessels
in any convenient manner according to the construction of the same, and can be
secured to earthenware and other vessels by means of india-rubber and other equivalent
means.
To prevent the hinged cap or cover closing when emptying a bottle or vessel I
provide a spring or other substitutes.

and other Vessels.
I, JAMES HASLAM of 229 Bury Road, Tonge near Bolton in the County of
Lancaster, Chemical Fire Engine Manufacturer and Tin Plate Worker, do hereby
declare the nature of my said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to improvements in nozzles for chemical fire extinguishers
and other vessels, such as, metallic and other bottles, closed cisterns or tanks, liquid
carts, and others, and consists in providing ready and efficient means for either filling
or emptying the same.
In carrying out my invention I provide a nozzle with a hinged cap or cover; the
latter being provided with a cavity to receive an india-rubber or other joint ring
secured in any convenient manner to form a tight joint when closed over the inlet
of the nozzle. When the hinged cap or cover is placed over the nozzle it is secured
in position by a swivelling handle or its equivalent provided with a lip which slides
under a bayonet or other projection on the outside of the nozzle.
This invention, or part of it, may be applied to existing bottles and other vessels
in any convenient manner according to the construction of the same, and can be
secured to earthenware and other vessels by means of india-rubber and other
equivalent means.
Fig. 1 is a sectional elevation of my improved cup or cover-Fig. is a plan of
Same- Fig. 3 is a sectional plan through line A' B' in Fig. 1, and Fig. 4 is a part
side elevation of nozzle with bayonet fastening.
A is the nozzle, the lower end of which may be made in any suitable manner
according to the class or form of vessel it is intended to be applied to. On the outside
of the nozzle A is disposed the projection B, to which is attached the hinged cap or
cover C by the pin D. The cap or cover is provided with the cavity E to receive
the ring G, which may be of india-rubber, gutta-percha, or other substance most
beneficial for the purpose the vessel is intended to be used. On the hinged cap or
cover is mounted the swivelling handle H on the pivot or centre I, being secured
thereon by the ferrule J or in any other convenient manner. To the swivelling
handle H is attached the lip K which slides under the bayonet or other projection L
on the outside of the nozzle A when the hinged cap or cover C is closed over the
nozzle A as shown in Figs. 1 and 2. When the hinged cap or cover C is closed
the ring G is pressed onto the outer edge M of the nozzle A, by which a perfectly
tight joint is made, the pressure being imparted by the action of the lip K on the
swivelling handle H in sliding under the bayonet projection L.
When it is intended to raise the hinged cap or cover the handle H is swivelled
sideways as in dotted lines in Fig. 2, thereby removing the lip K from under the
projection I.

page_text: If desired the nozzle A can be provided with two projections L, the handle H
having the lips K to slide under the said projections L as shown on plan in
Figs. 6 and 7.
When it is necessary to raise the hinged cap or cover the double handle H is
swivelled into the position shown in dotted lines in Fig. 7.
Fig. 5 is a part sectional olevation of a bottle with my improved cap or cover and
nozzle applied.
The lower end of the nozzle A is fitted to or bent under the head N of the bottle O
as shown, or in any other convenient manner. The joint between the mouth of the
bottle O and the underside of the nozzle A is made by means of the ring P, which
may be of india-rubber, cement, or any other suitable substance.
Fig. 8 is a part sectional elevation of a bottle or other similar vessel with my
improved cap or cover applied. In this arrangement the nozzle is formed with the
bottle or other similar vessel, which may be of earthenware, glass, india-rubber,
gutta-percha, composition, or of any suitable metallic materials with the projections B
and Lattached thereto. The top end of the nozzle is provided with the facing M
on which the ring & sits when the cap or cover C is closed. The cap or cover C
and the swivelling handle H can be of earthenware, glass, india-rubber, gutta-percha,
composition, or of any suitable metallic materials; or of a combination of the same,
having the cavity E with the ring G.
If desired the nozzle A with the projections B and L can be made of india-
rubber, gutta-porcha, composition, or other elastic or pliable material which can be
sprung or pressed on the neck or outlet of the bottle or other vessel, in either a
cold or heated state, as shown in Fig. 9. In this case the cap or cover C and the
swivelling handle H can be made of a similar substance to the nozzle, or of suitable
metallic or other materials, or of a combination of materials.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declaro that what I
claim is :-
==
1. The construction, combination, and arrangement of apparatus consisting of the
nozzle A with the projections B and L and the pin D, hinged_cap or cover C with
the ring G in the cavity E, swivelling handle El and the lip K pivoted to the cap
or cover C, applied and operating substantially as described and as shown on the
drawings in Figs. 1, 2, 3, 4, 5, 6, 7, and 9.
2. In combination with the nozzle or outlet of a bottle, closed cistern or tank,
liquid cart, and other similar vessel the use of the hinged cap or cover C and the
means for securing the same for the purpose specified, substantially as described and
illustrated on the drawings in Fig. 8.
