DEFLECTOR NOZZLES. 209 



Mr. J. T. Hay den, of Cambridge, Mass., secured in 1878 (No. 2052G7) 

 the pattern in Plate XXI, Fig. 3. It is a liose-pipe which discharges 

 from the plug-hole, c. Beyond the plug, B, is a shortened barrel, so ex- 

 panded that the plug, B, as shown in section, can have its passage, c, set 

 to discharge against the side of the short barrel, which then serves as a 

 deflector, and spray is thrown from a concave, semicylindrical portion 

 of its surface. 



Another simple device for this purpose is that in a patent issued in 

 1881 {No. 238295) to Mr. J. W. Killam, of Lakew^od, N. J., and pre- 

 sented in Plate XXI, Fig. 4. The scoop-shaped plate, D, is provided 

 with a socket, B, which can be forced over the jet-pipe, A, when a spray 

 is desired, or may be removed to use the solid jet. 



Eecently the nozzle presented in Plate XIX, Figs. 6 and 7, manufact- 

 ured by Mr. P. C. Lewis, of Catskill, X. Y., along with his combination 

 force-pump, described further on, has come to our notice. The adjust- 

 ment of the small deflecting plate, pj is admirable. The plate extends 

 backward beneath the spout as a narrow slide-bar,^', through the loops, 

 uu, of the rings, r r, and terminates in a bent eye. By pulling this 

 back with the finger the deflecting part of the plate, jp, is drawn under 

 the end of the spout, to which it clings firmly by springing up tightly 

 against it. Thus the unimpeded solid jet is used, and the same may be 

 instantly converted into a spray by pushing the plate forward. This 

 deflector is very small, neat, and well made of brass. The front edge 

 is rounded, but in the same plane with the rest of the plate, which is 

 very narrow, with its sides nearly parallel. The spray is of a form suited 

 better for sprinkling trees, windows, and houses, but for broadcast work 

 on the ground or over low vegetation a square and broader spray with- 

 out ragged borders and with the margins and median parts equally 

 dense would be preferable. 



One of the deflectors, sent by Mr. J. Schier, of Ellinger, Tex., is 

 represented in Plate XIX, Fig. 5. The median prominence of the plate 

 spreads the water more towards the margins and thins its center. 

 Thereby is sought a spray of greater width, with its middle made as 

 thin as its sides. The back of the tin plate is stiffened by an additional 

 layer of tin and a thick mass of solder, while its neck has a short brass 

 screw attachment, a, to the spout. 



Another of a similar pattern, but entirely of brass, has the plate de- 

 tachable so the solid jet may be used when desired as in Fig. 4. The 

 deflector, 2^1 is soldered to a ring, u, which may be unscrewed from the 

 spout, a. 



Mr. J. A. Barrett has secured a patent in (Xo. 239305) 1881 which 

 seems to cover the foregoing idea, or the principle of dividing the jet 

 into a spray by an angular deflector shown, at a, in Plate XXI, Fig. 5, 

 where its edge is represented as projecting into the jet, s, from the hose- 

 pipe, e, upon which the shank, b and c, of the deflector is clamped by the 

 spring, d. It is asserted that ^' no backward flow or general spattering of
