This invention relates to apparatus for distributing a fire preventing and extinguishin composition.

lBroa ly the present invention consists of a means for spraying a fire-extinguisher from the air, by. means of. storage tanks borne by airplanes, these tanks helng situated below and at the sides of the fusela e in such-a manner as to afiect but slightly, if at all, the gravity of the machine under flying conditions, the tank arrangement being preferably three in number, with the largest in the center flanked upon either side by a smaller, these two being oi'f equal size and connected with the central one by passaes permitting the liquid to flow from one to te.

other in maintenance of equilibrium, the central tank being provided with a s rayrearvvardly and ownwardly from the fuselage and controlled by a valve operable by the pilot ot the airplane, for the government of liquid distribution.

This means of fire-fighting, especially forest, grass, or grain fires, has many and decided advantages over the ordinary ones usually em loyed in such emergencies, providing the reghter with an elevated point of observation, a speedy means for change of lield of action, and the facilities for covering speedily large areas with an eflective anti-pyro composition, this eficiency being of equal value in fire prevention and fire extinguishment. I

The principal object of this invention is the provision of means for showering, or spraying,a fire preventing and extinguishing element upon wooded, or other areas, either as a precaution against fires or for their extinguishment once started.

Other objectsand advantages of this invention will appear as this specification progresses and be brought out more-clearly in the claim hereto appended.

In the accompanying drawings, forming a part of this specification, and in which sunilar characters of reference refer to like parts, throughout,

Figure l is a perspective view of an'airplane in flight, showing an embodiment of my invention in the form of elongated tanks,

referably three in number, secured in place helow the lower wing of the plane and connected together by passages, the central tank carrying a sprayingnozzle at its rear extremity adapted to spray liquid from the its rear end carrying tanks in a fan-like shower directed rearvvardly from the plane, to fall in shower upon the area to be covered and controllable by the pilot of the machine;

lgure 2 is an enlarged front elevation, showing the arrangement of the several tanks, together with their Figure 3 is an enlarged side elevation, partly ln'section, of the rear portion of the central tank, showing its reduced neck at g the valve and spraying nozzle, and the valve operating mechanism. Referring in greater detail to the draw lngs, and with reference more particularly to Figures 1 and 2, 1 indicates an ordinary a rplane comprised of wings and fuselage 2, to which are attacheda plurality of elongated tanks 3, t and 5 by means of straps, or like supports, 6 and 7, the tanks being constructed to conform as nearly as may be to the contour of the fuselage and fitted tightly thereagainst, as represented at 8, 9 and 10, n Figure 2, and extending therealong with stream-line efiect and. central digmetcrs greater than those of their extremiies.

{The

smaller tanks

3 and 5 are oppositely dis osed along the sides of the fuselage, wit the larger tank 4 intermediate these but directly beneath the fuselage and extending in a direction tudinal axis, with capacities, respectivel of 7 5 gallons each for the smaller ones an 100 gallons for the lar er one.

I The

flanking t s

3 and 5 are connected, respectively, to the central one 4 b short pipe-line connections 11 and 12, orming a common passageway between all three tanks, permittin freely from flan 'ing tanks into the central one when flying in anapproximate horizontal plane, or from tank to tank seeking the lower level, when banking, to maintain stable equilibrium.

The

smaller tanks

3 and 5 are provided with

filling necks

13 and 14 bearlng caps 15 and 16, as a means through which the three tanks may receive their liquid charges.

.The posterior extension of the tank 4 projects downwardly at an angular inclination to that of the longitudinal axis of the tank, terminating in a goose-neck l7 threaded at its lower end 18 for the reception of a sprayconnections; and

paralleling its longithe liquid content to flow ing-nozzle '19, as shown in Fi ures 1 and Jill lever 30, located Within the fuselage and conveniently reached by pilot or observer. i A telescope may be mounted on the weelage at any point convenient for observation, sis indicated by 31, and suitably supported lay swiveled bearing and braces 32, for the ready detection and location of fires in areas being flown over.

The filling caps may he provided With valves 33 and 34:, through which pressure may le supplied the tanks; it it be desired to employ this means as a force in their discharge, on, through their opening, to provide breathing vents for the admission of atmospheric pressure to facilitate the flow of the contained liquid.

Having thus described any invention, l claim, and desire to secure by Letters Patent:

neoaaeo lln a device of the character described, the combination of an airplane, three liquid bearing tanks attached to the outer surface of the fuselage of the airplane and extending longitudinally thereof, the inner Walls of said tanks being so shaped as to conform to the contour of the Walls of said fuselage and triangularlv positioned relative to each i other, the flanking tanks being of like form and equal in capacity and positioned in a common plane below and paralleling that of the horizontal plane of the longitudinal axis of the airplanes fuselage, the central tank being of a capacity not less than that of a flanking tank and positioned below the inselage, the said flanking tanks having connecting passageways leading to said central tank to permit the free flow of liquid from tank to tank to maintain equilibrium, the central tank being provided with a real- Wardly projecting neck hearing a valve-controlled spraying nozzle and valve-actuating connections extending from said" spraying nozzle to the ioclrpit of "he airplane for con trolling the fluid discharge through said nozzle.

in testimony whereof I have affixed my signature.
