A further object of our invention is to so It is important, in order to accomplish the construct the device that the inside pipe is requirements fulfilled by our invention, that more readily accessible, when it is desired to the part B be capable of revolving with maxi- 95' 45 remove it for inspection or repair, than in mum rapidity and without jerk caused by those heretofore constructed. -momentary complete-or partial stoppages and These objects are accomplished by the constarts while the pressure is on. 'lo this end struction lillustrated in the accompanying we provide a greater number of openings, D', drawings, in which- A than there are wings, C, and secure within roo 5o Figure lis a longitudinal section of our the tube a frame, D2, for. each of said openimproved spraying-nozzle with the shield and ings, each of said frames being closed at its top and bottom and having its opposite sides arranged diagonally; said frames thereby forming diagonal passageways to the openings, D', and causing the water to be discharged diagonally from said inner tube. By closing the passageways at the top and bottom the water is caused more positively t0 issue diagonally from the tube than it would if the passages were lett open at the top and bottom, as will be readily seen. As the wings, C, are located in the longitudinal center of the revoluble chamber the pressure is equalized at both top and bottom so that the chamber will revolve with maximum steadiness.

In practice we prefer to provide live passages or openings from the tube to three wings, whereby theside of each wing will be struck in succession by the water issuing diagonally from the inner tube and at no time, in the rotation of the revoluble chamber, B, will the wings he so located with respect to said openings that one or more of the former will not be struck by and receive the full force of the stream or streams issuing from one or more of the latter. Thus it will be seen that by the number, location and form of the passages and wings the full power of the direct pressure of water will be received by the wings and that such pressure is equal throughout the length ot' the revoluble chamber, whereby said revoluble chamber is capable of being revolved with maximum rapidity and without jerk. It will be further seen that as the part B is supported entirely, or almost so, by a swivel connection at its upper end with the stationary part, A, it may revolve with the greatest freedom as there is very little friction to overcome. Practical experience has demonstrated that in a nozzle coustructed as above set forth the water will issue from it in solid sheets and with great force, thereby effectively covering a great area and, in addition thereto, creating an air current or a force which will dissipate the smoke in its immediate vicinity and force the same forward away from it to such an extent as to enable firemen, unprovided with liremens respirators, to enter with it and iight re in closed rooms, or in other placeswhere the smoke is dense, without danger of being overcome by the heat or suiocated by the gases in the smoke.

The upper end of the inner tube, D, is formed with an outwardly-extending flange, d, which rests opon the oit-set, a, and is secured thereto by means of screws, Z, while the lower end of said tube is closed and formed with an opening or recess, c', which receives the upper end of a post E. This post extends entirely through and beyond the bottom of the revoluble chamber, B, and its portion within the nozzle is round in crosssection, so as not to interfere with the free rotation of said part B, while its portion exterior thereto is externally-screw-threaded and is engaged by a nut E. By thus securing the tube in place it can be quickly and support for the revoluble chamber, B, and

consequently it is not located in close frictional contact therewith, so that there is no friction at the forward end of the nozzle to retard the movement of the revoluble chamber, but when the revoluble chamber is revolving at an extremely high speed--for eX- ample, under a pressure of from two hundred to two hundred and fifty pounds tothe square inch-there may be, (notwithstanding that the pressure is equalized throughout the length of the revoluble chamber by the position of the wings, as above stated,) a-tendency for such chamber to wabble, and to overcome this tendency we prefer to locate the nut sufficiently near to the bottom ofthe chamber whereby it, in connection with the post, EV

and position of the wings will positively overcome all tendency of the chamber to Wabble under any circumstances.

It will be observed that in addition to the usual forwardly and outwardly inclined openings in the revoluble chamber We provide said chamber with a series of rearwardly-inclined openings, b. These openings are of prime importance because, when the nozzle is let down into a room where there is a fire which it is desired to extinguish the Water issuing from such openings, b', will protect the hose by extinguishing fire upon the rafters, or woodwork, or other inflammable material surrounding the hose.

F designates a coupling collar, which is of the ordinary and well known construction, and, as usual, is attached to the hose F. Into this coupling collar the upper end of the nozzle is screwed, the partAot the latter being formed with external screw-threads a, for this purpose.

G designates a shield which projects considerably' beyond the coupling-collar and has its main part inclined. This shield is made in two separate parts, or ol' two segments, g and g', each of which is formed with an upwardly-extending flange, g2 surrounding the central spring which receives the coupling F said flange, having openings, g3, to receive the lugs,f, of said coupling collar F.

g4 designates lugs which are secured to, or formed integral with the adjacent ends of the shield-segments, and one of which is formed with a threaded-perforation for the passage of a thumb-screw, g5, by means of which said ends of the shield-segments are drawn together and the shield clamped in position: and gG and 97 respectively designate a link and a hook which are secured to the other ends of the respective shield-segments and IOO IIO

clamping means at the -free ends of the sec-1 tions and by the vengagement of the lugs of v place it will protect the Iiremen from the wa the coupling collarl with the openings in the iianges of the shield. When thus secured in ter issuing from the uppermost rearwardlyinclined openings, b', of the revoluble chamber when the firemen are directing the streams of water from the room in which the lire is located; and, inthe event that the nozzle isk ing is left uncovered a draft will be created which will feed the fire. This shield will also aid in protecting the firemen from smoke and heat.

Although wehave described our invention as being a part of the firemens hose, and therefore to be carried around by the iiremen for use as occasion demands, it is, obviously, equally as well adapted for permanent connection with the stand-pipes of large buildings and may be located in any or all of the rooms of such buildings and serve as a part of the safety appliance thereof.

Having now described our invention, what we believe to be new, and desire to secure by Letters Patent, and whatwe therefore claim,

l. In a spraying nozzle, the combination of a revoluble perforated chamber, a plurality of Wings secured to the inner wall of said perforated chamber, a stationary tube having a plurality of openings opposite said wings, and frames secured to the inner wall of said tube adjacent to said openings, said frames being arranged to form diagonal passageways to said openings and said passageways being Iclosed at their tops and bottoms, substantially as described and for the purposes set forth.
