Specification of Letters Patent.

Patented Mar. 7, 1916.

Application filed March 22, 1913. Serial No. 756,195.

To all whom it may concern:

Be it known that I, EDWIN G. ADAMS, a citizen of the United States, residing at Marysville, in the county of Union and State of Ohio, have invented new and useful Improvement-s in Automatic Fire-Extinguishers, of which the following is a specification.

The invention provides novel means for protecting a dwelling or other structure from destruction by fire and which is automatic in operation and which in practice serves to scatter or distribute the fire extinguishin g medium.

The invention consists of a receptacle adapted to contain a fire extinguishing liquid which when liberated serves to smother and ultimately extinguish a fire. Mountings are provided for such receptacle and are of a nature as to admit of the receptacle receiving a swinging action, whereby the contents when discharging are at the same time scattered over a comparatively large area and automatically smothers the fire. The mounting for the receptacle includes means for retaining the parts in normal position which means are affected by abnormal temperature to admit of a release of the receptacle and its supporting means, with the result that the receptacle is inverted to discharge its contents and at the same time automatically receives a swaying movement which scatters the contents of the receptacle simultaneously with its discharge.

The invention ccnsists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawing, and pointed out, in the appended claim.

Referring to the drawing, forming a part of the specification, Figure 1 is a side View of an automatic fire extinguisher embodying the invention, the full lines showing the normal position of the parts and the dotted lines indicating the position of the receptacle when released and swung into pendent position. Fig. 2 is a horizontal section. Fig. 3 is a rear View.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawing, by the same reference characters.

The numeral 1 designates a receptacle which may be of any construction and which receives the fire extinguishing liquid, of any well known mixture as to produce a gas which will smother a fire and extinguish the same. A stopper 2 closes the-receptacle and fits the same loosely so as to be readily dislodged when the receptacle is inverted, thereby admitting of the contents discharging freely. The receptacle 1 usually eon sists of a glass bottle which is protected by means of a jacket 3. The mounting for the jacket of the receptacle comprises a base a and ahanger 5. The parts 4: and 5 may be of any construction. 'Thereceptacle is pivctally connected by means of the jacket 3 to the lower end of the hanger 5, the ccnnection'being located at a lower corner of the jacket to admit of the latter swinging into pendent position when released. as indicated by the dotted lines in Fig. 1. Under normal conditions the receptacle 1 is supported in upright position, as indicated by the full lines in Fig. 1, the connection 6 consisting of a fusible wire or string which is affected by abnormal temperature to admit of the re ceptacle being released and swinging into position indicated by the dotted lines in Fig. S0 1 so that the contents may discharge. When the receptacle is liberated and swings into pendent position it has a swaying movement imparted thereto which serves to scatter or distribute the fire extinguishing medium which will smother and finally extinguish the fire. The stopper 2 may be of any suitable material, preferably glass to fit loosely in the bottle, and yet havesufficicnt weight so that when the receptacle is liberated and swings into pendent position the stopper will drop to the floor and allow the contents to be distributed over a large area to insure smothering of the fire.

A room or other apartment may be supplied with any number of fire extinguishers embodying the invention, the same being sopositioned as to insure thorough and effective protection. It is to be understood that such fire extinguishers are located in an ele- 10o vated position, it being preferred to attach them by means of the base f to the ceiling so that when the receptacle is liberated from the holding means 6 it may swing into pendent position and at the same time sway so as to scatter or distribute the contents simultaneously with the discharge thereof from the receptacle.

From the foregoing description, taken in connection with the accompanying drawing, 11 the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and

that such changes may be made when desired as are within the scope of the claim appended hereto.

Having thus described the invention what is claimed as new, is

A support for an automatic fire extinguisher comprising a plate adapted to be at- ,7

tached to an overhead support, a hanger pivotally connected to one side of the plate and having means for swingingly connecting the bottom of the extinguisher thereto, and a fusible element connected to the opposite EDWIN G. ADAMS. Witnesses:
