1 Claim.

This invention relates to an improved mounting for fire extinguishers and aims to provide safety means whereby-once a fire extinguisher has been removed from its mounting it cannot again be placed thereon except by an authorized person.

The improved device includes a fire extinguisher supporting means which automatically moves to non-supporting position and is locked therein upon removal of the fire extinguisher.

The above and more detailed features of the invention will be fully apparent from the following specification, when read in connection with the accompanying drawing, in which:

Figure 1'15 a .front elevation with portions broken away showing the improved hanger supporting a fire "extinguisher in position to be used;

Figure2 is a side elevation thereof; and

Figures 3 and 4' are views similar to Figures 1 and 2 but showing the position of the parts after removal of the fire extinguisher.

Referring in detail to the drawing, l0 represents a base plate having guides 42 and M for slidably positioning a slide member it which is provided at its lower extremity with a supporting 25 shelf or hook l8 adapted to support a fire extinguisher, indicated at 20.

A spring 22 has one end secured-to a stud 24 carried by the slide 16 and its other end secured to a fixed anchorage pin 26 carried by the base plate l0 and projecting through a slot 28 formed in the slide. A cover 3|! encloses the slide and serves to prevent unauthorized persons from'gaining access to locking mechanism to be presently described. 35 Enclosed by the cover 30 there is a locking mechanism which is efiective to prevent unauthorized persons from moving the supporting slide from the position of Figures 3 and 4 to that of Figures 1 and 2. The locking means illustrated includes a latch dog 32 which is pivoted at 34 and normally pressed toward the edge of the slide I6 by a springiifi. The dog has anoutwardly bent lip 38 at its free end forcoaction with a locking notch 40 formed in the slide. Coincident with the pivotal axis 34 and secured to the dog there is a sleeve-like member having recessed portions adapted to cooperate with a suitable key which may be inserted through a keyhole 38 formed in the casing.

While the drawing shows one known type of small fire extinguisher resting bodily on the shelf or hook it, it is clear that a much larger'extinguisher, generally known as the soda-acidtype, can be hung Vertically therefrom by engaging the handle thereof with said hook 48.

With the apparatus described it will be apparent that when the fire extinguisher 28 is re moved from the supporting portion 28, the spring 22 will retract the slide and thus move the sup-- porting portion I8 to theposition of Figure 4 wherein it is apparent that it is inaccessible. The slide will be locked in this position by the dog 32 and it cannot be again moved to a position to receive a fire extinguisher until an authorized person in possession of the key unlocks the dog and moves the slide to the position of Figures 9 1 and 2. I

While I have described quite specifically the embodiment of the invention herein illustrated, it is to be understood that various modifications may be made by those skilled in theart without departure. from the invention, as defined in the appended claim.

ing a key engaging portion, said cover having an aperture aligned therewith, said slide being a one-piece flat element with an angularly bent extremity to form said suppi rting portion, and said base plate being a single fiat member and having integral guides bent into overlapping relationwith'said slide. l
