SPECIFICATION forming part of Letters Patent No. 599,330, dated February 22, 1898. Application filed February 17, 189.7. Serial No. 623,857. (No model.)

To (tu whom. it may concern: Be it known that I, GEORGE C. HALE, a citi- Oity, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in 'Ehre-Extinguishers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it'appertains to make and use the saine. i In the application of a lire-extinguishing system to a grain-elevator or other structure where dust is' continually iiying in the atmosphere provision must be made for preventing the" lcdgment andaccumulation of the dust to become iilled and choked up by the accumulation of dustV to such an extent as to seriously impede y'l'.iie flow of Water.

Previous to my invention it has been pro-I posed to close the outlet port or nozzle by a of the tire and to employ a valve held in place by a separable device normally maintained mechanicalappliances; but in such prior devices all the nozzles or outlets are closed by means. which require solder to be melted by the heat before it is possible for water to es` cape in extinguishing the lire.

It is the object of my present invention to provide in a system for extinguishing fires a simple and inexpensive contrivance which will serve the dual purpose of closing-the exit ports or nozzles` against the accumulation therein of dust and dirt and as a dis'tributer for the water as it spurts-or jets under pressure from the supplyqnain of the extinguishing system.

To the accomplishment of these ends my invention consists in a nre-,extinguishing system Vespecially adapted for grain-,elevators and other places where dust is liable to clog up the discharge-ports,. in the combination, With a Water pipe or mainhaving a discharge or face thereof,vv ofa distrihntershead mounted ited movement toward orfrom Vthe same and to have a tree rotary movementin` aplaneap? proximately parallel-to the axial line of the pipe or main, said distributer-head being so combined and arranged that it will automatically seat itself by gravity. upon the pipe or main, so-as to close the portl or nozzle therein against the accumulation of dust or dirt, said distributer-head lying in the path of the jet or stream of water-which byimpingin g thereon keeps the distributer raised abovethe pipe or main and causes the same to be rotated for the purpose of breaking up the jet or stream of water and throwingit upon the adjacent surfaces to aid in extinguishing the fire or to satuL rate with water said surfecesto prevent the spreadof a fire; and the invention further consists in the novel combination of devices and in the construction and arrangementof parts which will vhereinafter be fully described and claimed.

To enable others to understand my invention, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in Which- Figure l is an elevationof part of a iireextinguishing system, showing a series of distributers applied to one of the pipes or mains thereof. Fig. 2 is a vertical sectional elevation, on an enlarged scale, of a part of the pipe or main and one of the distributers, the dotted line showing the distributer in its unseated l raised position for throwing outwardly the jet or stream of Water. Fig. 3 is a detail perspective vieW of the distributer-head, Fig. l is a detail view of one form of the bracket which may be used to support the distributer- MLike numerals of reference denote corresponding parts in all .the flg'ures of the drawings, referring to which- .A l designates one of the pipes or mains of a' fire-extinguishing system, which system embraces a series of pipes arranged in thevarious parts of a grain-elevator, building, &o.. .which ,head in operative relation to the main or pipe` may be most exposed to danger from ,coniaa branch service-pipe leading to a supplytank, a servicemain, or to a suitable place vaccessible by .firemen for the attachment or' hose-from a fire engine or steamer, whereby Yfull supply of water maybe had for tbepurA l grations, and the system further provided with I .e isprovided for the and its spindle may have around the port or nozzle 2 In the embodiment of my invention Iherein shown the bracket has aseatflike plate 5, concaved on its lower face to iit snugly upon the pip-e and having grooves G in its upper face to accommodate the clamping wires or bands 7, which pass around the pipe andare fastened in place thereon by twisting the ends thereof togeth cui-ely clampe porter nozzle d in position adjacent to the 2 3 but it is evident that other means may be employed to clamp the brack- 'etsinplace With this seat-plate 5 is made as anfintegral part thereofthe overhanging arm 8, which is arched upwardly over the pipe, the free end of said arm terminating in anelongated vertical bearing f). This vertical bearing is in axial alinement vertically with theY port or nozzle'2in the pipe 1,-and Athe upper end of said bearing is closed,wliile the lower end of the bearing 4is open. The opening in the bearing terminates in a conical end, (indicated at 10 in Fig.'2,`)" which forms an end bearing or step for the upper conical end of,the spindle 12 on the'distributer-head ,wlierebya limited bearing-surface end of the spindle, which reduces to a minimum the friction and wear on thev coact-ing bearing-and spindle of the distriouter-head'when the latter is raised and is rotated by ter on its spiral blades. Thisdistributerhead is in the ferm of an inverted cone, and said conicalhead and the spindle 12 are made or cast in a. single piece of metal, although this is not strictly necessary. On the lower conical working surface of the distributerhead is provided aseries of propeller-blades 13,v which extend in spiral lines from the upper neutral edge of the head down the surface of the cone to a point above the apex of the cone, said apex of the cone being unobstructed by orffree from the blades, as indicated at 14 in Fig. 3.

The-bracket 3 and the distributerdiead are so arranged and proportionedtiiat the head a limited vertical play relatively to the pipe 1. in its normal position the vweight or gravity of the head and its spindle causes the head to descend and rest-upon the pipe, in which position the apex 14: of the cone fits in thc port or nozzle 2 of thepi-pe. As the broad surface of the inverted cone covers a certain area of the pipe,

therein, it is evident that the distributer-head protects the side vit is provided with a er, whereby the bracket is se? .the impact of the escaping wa-v l ter is rotated and at parting from the :a bracket on port or nozzle 2 against the accumulation of dust or dirt, because the dust cannot have access to the port, in which is fitted the ape-Xv 14 of the head, and the dust will lodge and ac- 7o cumulate 'upon the broad surface of the conical head. The spindle 12 is adapted to slide a limited distance in the bearing of the bracket,

and it is also free to rotate therein, and when and spindl'e'elre raised to their full 75 the impact of the water thereon the v When water under pressure is admitted 8o tothe extinguishing system either from a supply-tank or a service-mainv .or from the hose of a' fire-steamer, it rushes through the4 pipes until it finds outletinthe ports or nozzles 2, the pressure of the,

headsabove the pipes. Thespindle of each head slides in the bearing with the distributer-head until, the end of the spindle abuts water being more 85 than sufficient' to lift all 'of the .distributeragainst the upper conical end of the bearing, 9o

and as the jet or stream against the spiral blades on the head the latthe same time held in its raised position, whereby the rotary head of water impinges serves to break up the solid jet and throw 95 the water in the form of a spray upon the adjacent surfaces of a building to assist in eX-aI tinguishing the iire or to saturate the parts with WaterQsoa'sto reduce to av minimum the" spread of the tire.' .A

I am aware that changes intheform and proportion of parts and in the details of construction herein shown and'described as the be made by a skilled mechanic without despirit or sacrificing the advantages of my invention, and i therefor-ereserve the right to make such modifications' and alterations as fairly fall within the scope of my invention.

4Having tion,what I claim asnew, and desire to obtain by Letters Patent, is l 1. The combination of a pipe or main having an outlet port or nozzle in its upper side,

said pipe` adjacent to said nozzle or port, and a rotatable distributer-head having a spindle slidably iitted in said bracket and provided with spiral blades which ter-v minate within the lower extremity of said head, thus forming on the4 head a surface adapted to snugly fit in the port or nozzle, for the purposes described, substantially as set forth.

2. The combination'with a pipe or main provided in its upper side with an outlet port or nozzle, a vbracket attached to said pipe and having an overhanging arm over the port, and an inverted conical distribnter-head having a spindle slidably fitted in the arm of the bracket, said conical seated by gravity for its apen to dt in,and close .preferred embodiment of my invention may hereinfully described my invenv head adapted to be the port or nozzle, and provided With spiral blades, for the purposes described, substantaily es set forth. l Y
