t le/omit may concerns 1 known that I, AUoUsTUs' SCHMIDT, tizeii of-the" United States, residing at Indi'aiiapolis, inlhe county of Marion and tate'ofI-ndiana, have invented certain new useful improvements in- Distributingflx ozzl'es, of which the following is a specifica- 'tioiij 7 This invention relates to nozzles for disuo ftributing.water, andcontains principles of 'jcsn a aion to permit it to be classified 1 *with 'tliose nozzles known as the fusible l "itypeywhich are attachedto the pipe lines feliiployed for protecting buildings against the 'sproadingcf lire; the nozzle being provid lwith a fusible-lock that is capable of [bei set oil by the action of the heat and thus causethe' water to be released automatically. [:TlhefL ob ectOi" the invention is to provide 0 Figure 1 is the top or plan view of my distributing nozzle in action, and shows how the several sheets of water overlap one another to form a continuous circular sheet of water around said nozzle. Fig. 2 is the side elevation of the nozzle in operation and further illustrates the relation and courses of the several sheets of water as they recede from the nozzle. Fig. 3 is a side elevation of the nozzle and shows the relative location of the slots through which the water is discharged.

Fig. 4 is a view similar to except that the fusible-lock and valve are open, as when the nozzle is in operation. Fig. 5 is a central vertical sectional view of the nozzle. Fig. 6 is a plan view of the fusible-lock. Fig. 7 is a horizontal sectional view of the fusible-loch on. the dotted line 7 7 in Fig. 5.

The distributing nozzle consists of an almost spherical hollow shell or ball 15, provi led with an inlet orifice at its top. This orifice has internal threads and receives a threaded sleeve 14., having its lower. and inner edge out flaringly to form a valve-seat for the valve 17. The upper portion of the sleeve 14 is provided with external threads by which suitable connection can be made Y nure s'rn'rns ATENT OFFICE.-

with hose or piping, this depending on the nature of the work expected of'the nozzle.

The chiefleature of my invention, consists in providlng the hollow'ball 15, with a plurality of long, narrow, slots 16, which are staggered with relationto one another, so

that thin, wide, sheets of water which overlap one another, are, thrown from the nozzle,

thereby insuring a thorough drenching of the surface area lying within the capacity of the nozzle. The distribution of water from the slots and their relative arrangement, as shown in the drawings, will insure amore' perfect drenching within the capacity of the nozzle than those nozzles having. numerous perforations, for, in the lattef, there is no arrangement whereby the streams maypositively be dlrected so that they will overlap one another. I I

Thenozzle is ,providedwith a valve 17 which rests, normally against and seals the lower end of the sleeve 1'6, and-lioldsthe water back. The valve is provided with a stem 18 which extends downward and through an aperture in the boss 20onthe yoke 21, which forms a frame for a fusible locking device. The boss 20 has external threads and is screwed in to the threaded" aperture located in the hollow ball 15. The yoke 21 is formed by cutting away its central portion and leaving the end extensions 22. These extensions are provided with slots 23, which receive the plates 24, and these plates are pivotally retained by the transverse pins 25. These plates are secured together with fusible meta and form a support for the valve stem 18, and by which means the valve 17 is held to normally close the inlet to the hollow ball 15. I have found by experience that the pressure of the water against the face of the valve 17 may be of such force as to cause accidental separation of the plates 24, thereby prematurely openthe valve-stem 18 when the'plates 24 sepa rate, I form the slots 23 in the extension 22 of the yoke 21 somewhat wider than the ,thickness' of the plates 2-4, while the opposite sides and ends of said slots are cut on a taper (see Figs. 6 and 7)- which permit the 'lates .to spread (as shown 'byvthe dotted ines in Fig. 6)' and allow the valve stem 18 "to ass uninterruptedly between them.

' aving thus fully described my said inof lik e' deg'fee may discharge, a valve for controlling t e inlet tosaid nozzle, a fusible locking device including the frame, extensions on saidfra'me, said extensions provided with slots having their opposite sides and ends cut on a taper overlapping plates pro- .vided with registering apertures pivotally secured to said extensions and resting in'the said slots, blocks adapted to be inserted into said registering apertures and fusible metal to hold said blocks in said apertures.

2. The combination, with a nozzle comprising a-hollow shell provided with long narrow slots arranged to overla one another, a valve to normally close t e inlet to said nozzle and provided with a valve-stem f adapted to 'extend eentrall through and to the exterior of said noz e, an adjustable means adapted to take over said valve-stem '35 and to form a base for securing the valve supporting plates, plates 'pivotally secured to said adjustable means and adapted to norvention, what I desire to secure by Letters i'Patent, is- 1. In a nozzle'of the character described comprising 'a hollow shell provided with long narrow slots through which sheets of water mally support the valve, non fusible blocks extending through said supporting plates and adapted to normally hold them together and fusible metal to hold said blocks in-position. V 3. The combination, with a nozzle comprising a hollow shell provided with long nar-r row slots which are arrangedto overlap one another,-a valve within said nozzle adapted to normally close the inlet thereto and provided with a valve-stem adapted to extend centrally through and to the exterior of said nozzle, an adjustable means engaging said nozzle and adapted both to take over said.

. valve-stem and form a base for securing. the

valve supporting plates, means for changing the relationship of the nozzle and said'ad justable' means, the latter means being provided with registering slots cut on oblique;

planes, valve supporting plates pivotally ar-' ranged within theoblique slots and adapted Y to normally overlap each other and support nine hundre' and seven. 1
