MANY-PUNCTURED NOZZLES. 195 



In such nozzles it is ecoDomy to pierce only those sections of the cross- 

 tube that come over the rows, and leave blank spaces with no spray be- 

 tween, as in the figure just referred to. Any i>erforated tube of this 

 character shonld have its ends closed by screw-caps or plugs. The 

 l)ipe can then be easily cleaned by opening these and i)assing tin^ough 

 a long handle bearing one of the cylindrical brushes nsed for cleaning 

 lamp chimneys. Small hand-nozzles of essentially the same form have 

 been made. One nsed by Mr. Warner on his '' Saddle-sprinkler," de- 

 scribed further on, has the cross-tube curved as in Plate XIV, Fig. G, 

 to throw the spray broader, and needs the imi)rovements just suggested. 



Divided kose-heads.-^A rose-head that separates from its neck, 

 or from a sohd jet-nozzle, by a clutch-coupling, which is the simplest 

 way of joining and detaching these parts quickly, is sold by I\[essrs. 

 Mast, Foos & Co., of Springfi^eld, Ohio. It also leaves the interior some- 

 what accessible for taking out materials which choke it. 



Mr. William Westlake, of Chicago, 111., patented in 1871 (Xo. 17 1221) 

 the use of the common sheet-metal can-screw as a large separable neck 

 for rose heads. In this waj^ can be made a very cheap sheet-metal rose, 

 as on Plate XIV, Fig. 7-, with a wide hole through which to remove 

 clogging materials from the interior. 



Bnt a still larger sheet-metal screw- coupling, separating the perfor- 

 ated face immediately from the body of the rose, as at r7, in Plate XV, 

 Fig. 2, was secured to Mr. L. B. Foss, of Boston, Mass., in 1876 (No. 

 174221). The preceding rose-heads are of cheap construction, and the 

 last-mentioned one is the best of the very cheap ones heretofore made 

 entirely of thin sheet-metal. 



Mr. S. H. Fox, of Saint Louis, Mo., patented in 1880 (Xo. 223332) a 

 strainer-nozzle, a plan- view of which is shown in Plate XIV, Fig. 8. It 

 consists of two concentric cylinders. The inner one is of fine wire gauze. 

 Through this the water entering by the inlet, «, must pass to the outer 

 cylinder before reaching the very finely perforated sprinkler- face which 

 emits the spray, s. This face is a screw-cap removable for cleaning. 

 Also the gauze cylinder may be renovated by taking off a similar cap 

 which bears the iidet-tube. This produces an uncommonly finely divided 

 spray for a nozzle of its class. 



Yet the idea of removing the perforated rose-face from its body by a 

 itit screw-juncture and screwing it on reversed, existed much earlier, 

 and w^as embodied in a patent in 1809 (Xo. 87321) by Mr. James Bar- 

 rows, of Hyde Park, Mass. 



Another good rose with the face reversible was obtained in 1875 

 (Patent Xo. 116164), by Mr. W. T. Vose, of Newtonville, Mass. A i)lan- 

 section of this is shown in Plate XV, Fig. 3, where a represents the neck 

 to be connected with a spout or solid-jet nozzle and c is a screw-band 

 which clamps the reversible circular face, ?>, to the walls of the chamber or 

 rose-head, a. Being constructed of brass, nicely finished, it is pi'obably 

 the most durable and serviceable rose-head made. A number of diller-
