EMERGENCY FIRE EXTINGUISHER Filed April 17, 1957 2 Sheets-Sheet 2 I INVENTOR. MANL/O S/MO/VC/N/ 6 (AELOS FALCON United States Patent EMERGENCY FIRE EXTINGUISHER Manlio Simoncini and Carlos Falcon, Bnenos Aires, Argentina Application April 17, 1957, Serial No. 653,321 3 Claims. (Cl. 169*35) The present invention refers to a fire extinguisher for emergency purposes and more particularly to a manual instrument which, in the manner it is presented for ready use, will solve one of the most serious problems created by the starting of a fire in cars, as well as in homes and other establishments.

This is represented in a flagon made of elastic material Which contains an extinguishing fluid and is sealed through the head of the spout, which also serves to suspend the unit, so that it will always be found in its place whenever an emergency arises; and since the suspension support has cutting means precisely in the plane where the head ends, same support serves as guillotine for decapitating the flagon, opening it at the same time, so that it may be used without loss of time.

This means that the efiiciency of the device resides in its instantaneous use without any complications.

In this manner will be avoided the inconvenience of the known type of apparatus which do not always respond to their opening mechanism and general operation, precisely at the moment it is most required.

Apart from what has been stated above, several are the objects pursued by the present invention amongst which may be stated the fact of providing a directional projector of fluid, so that the user may direct the jet towards .the principal centers of the fire, thus attacking in direct manner the fire from the very beginning.

Another object is that of obtaining with the flagon range of pressure, according to the needs in each case, so that the directed jet may reach heights or inaccessible places.

Another object of the invention is that of providing an apparatus with the full load of fire extinguishing material at an economical price.

Another object is to provide a fire extinguisher, ideal for automobiles, where it will always be ready to avert any accidental disaster.

The further objects of the present invention will be shown throughout the following specification which for a greater clearness and comprehension has been illustrated by several drawings in which:

Fig. 1 is a vertical section of the fire extinguisher set on the support where it may be seen pending from its head, which is to be cut when the flagon is removed from the support.

Fig. 2 is a plan view showing the head of the flagon partially broken away to show the spout opener which in this case has a double knife in V shape, so that when pulling the body, the head is lopped.

Fig. 3 is a graphic demonstration of how, when pulling the body, the head set on the spout is cut by the knives, so that it may be instantly used.

Fig. 4 shows the decapitation which permits the use of the flagon without loss of time.

Fig. 5 is an apparatus suspended in its support as in Fig. of being triangular, possesses movable blade by which the lopping is effected.

1 but with different lopping means, which instead Fig. 6 is a plan view of Fig. 5. A

Fig. 7 is an elevational view of the apparatus graphically showing the manner of grasping the flagon, whilst with the thumb the knife is operated, thus freeing the spout from the head, and finally Fig. 8 is a perspective view of the flagon in operation after its removal and decapitation.

In the different drawings the same reference numbers are used for equal or corresponding parts, the different elements designated by letters.

As may be seen in the drawing, a is the support, the base 1 of which may be fixed at any point or place in the house, motor car, etc., where the fire extinguisher is supposed to operate. 0n said support is mounted the flagon b which is made of an elastic or plastic material, such as polyethylene, so that the fluid contents may be projected through its spout 2 by manually squeezing the body of the container.

Spout 2 being hollow, is sealed by head 3, so that the whole flagon, such as it is provided from the manufacturer and while it has not been used, is sealed from the air in order to contain the fire extinguishing fluid in good condition for an indefinite period.

The flexible head 3 is of a sufliciently small diameter to be forced through opening 4 of support a, so that when said head has passed through the opening 4, it will remain as a button passed through a buttonhole, and since the section of the head 3 is larger than that of the opening, same will act as retaining means so that the flagon will be suspended in pending position (Figs. 1 and 5 The opening 5 in spout 2 extends up into the head, so that even if the spout is cut through the plane at the base of the head, it will still be open.

The spout 2, which is neck shaped extends through opening 4 so that if cut on the plane of support a it is ready for operating, by the outlet of the fluid contained therein.

Support a is provided with a knife c adapted to decapitate the head 3 as graphically shown in Figs. 4 and 8.

-In the examples of Figs. 1 to 4 the knife 0 is formed by a cutting edge 6 made in V shape in the border of opening 4 so that when grasping the flagon as in Fig. 3 and pulling same outwards, the cutting is done through the angular cutting edges separating head 3 from spout 2. In this manner the flagon is ready to operate by manually pressing the flexible walls, obtaining the necessary pressure for an effective projection.

In the example of Figs. 5 to 8 the knife 0 constitutes a manually actuated member 7 movable in guide 8 and has a digital key 9. The cutting edge 10 of member 7 is directed towards opening 4, so that when knife c slides as shown in Fig. 7, the spout 2 is cut separating it from the head 3.

Thus the apparatus shown in Fig. 5 in case of emergency is used by taking hold of the flagon b and pressing on key 9 so that the advancing knife edge 10 decapitates the head 3 and is ready for use as in Fig. 8.

Within the terms of the appended claims, various modifications of detail and structure may be made without departing from the scope or principles of the invention.

We claim:

1. An emergency fire extinguisher comprising a bag made from flexible resilient material terminating at one end in an integrally formed neck having a relatively narrow passage therethrough, said neck closed by an enlarged resilient button-like integral head and a fixed support for said bag having an opening therethrough of such size as to permit passing said head only when said head is distorted to reduce its peripheral dimension, the marginal edge of said support surrounding said opening con stituting a cutting edge whereby said bag is decapitated as ,it is pulled from said support to provide a nozzle having a cleanly severed discharge end for expelling extinguishing liquid in a jet stream.

2. The fire extinguisher of claim 1 wherein said marginal cutting edges are V-shaped;"

3. An emergency fire-extinguisher comprising a bag made from flexible resilient material terminating at one endin an integrally formed neck having a relatively narrow passage therethrough, said neck closed by an enlarged resilient button-like integral head and a fixed sup- 10 port for said bag havingan opening therethrough of such sizeas to permit-passing said head only whensaid head i8-1iSiQl'i. Bd to reduceits peripheral dimension, a knife member slidably supported in guides secured to said fixed support for movement across said opening and having a manual actuating key whereby said bag may be decapitated by pushing on said key to provide a nozzle having a cleanly severed discharge end for expelling extinguishing liquid in a jet stream.
