SLOT-NOZZLES.

juncture. This holds the plate off from the diagonally cut end of the 
spout while it may be depressed to diminish or close the outlet by 
screwing down upon it a flanged thumb-nut. Also, the tube crooks near 
the plate so that its stem or handle is parallel to the course of the spray. 
Its operation is not essentially different from that of the other nozzles 
just noticed. 
A slot-nozzle patented in No. 223402, January 6, 1880, by Mr. J. W. 
Stanton, of New York City, consists in a solid jet pipe with one-half its 
barrel longitudinally cut off at its discharge end and for some distance 
back so that the thumb can there be applied against the side of the 
stream to flatten and disperse it. 
Side slots. — The diagonal slot-nozzles have led us naturally to those 
which discharge from a slot in the side. Of this kind I have tested 
two or three different styles devised by Mr. John Schier, of Ellinger, 
Tex. Plate XVI, Fig. 8, shows his simplest sort, which is a vertical 
screw-cap, with a horizontal slit cut near its top. The slit, », is so dee}) 
as to throw a broad semicircular spray, while that in Plate XVI, Fig. 
1), differs only in having the spray divided into three with intervals be- 
tween. In this way the one nozzle may be made to supply three rows 
without wasting much spray between them. Either of these short cap 
nozzles can be screwed on the end of a vertical discharge pipe, and 
in ease of clogging can be removed by unscrewing them, while their 
shallowness makes the interior easily accessible. A third nozzle by the 
same inventor is represented in Plate XVI, Fig. 10. The part, c, is 
screwed on and separable from a screw fixed in a solid core, filling the 
center and one side of the tube, a. At one side of this core is an Upward 
slot-like passage leading to the horizontal outlet, the lower lip of which 
is the top margin of the spout, fl, while its upper. lip is the lower margin 
of the cap, 0, and hence the lips are taken apart when those parts arc 
separated. This gives better opportunity to clear out obstructions from 
the horizontal outlet and the vertical, semi -cylindrical slot within, which 
may also choke unless a very perfect straining process is used. The 
lever, f, is a thumb-piece by which to screw the short tube, a, on a pipe, 
and the vertical collar at its base is to prevent any poison from spurt- 
ing back toward the same, which points toward the operator. 
Dir. -1. 0. Melcher, of Black Jack Springs, Payette County. Tex., 
has furnished two varieties of this type of nozzle, which arc very sim- 
ple in construction, and may be briefly described as follows : The first 
is a simple T pipe of tin. with two slots cut crosswise of the tube and 
parallel with each other just opposite the juncture of the stem-pipe. 
The ends of the cross-pipe are closed, one having a cork or plug remova- 
ble for cleaning out the interior. The other nozzle is a simple L pipe 
forming an obtuse angle and having its distal end closed with a cross- 
wise slot near thereto. For comparatively coarse broadcast work these 
forms may be employed, and any of the coarse side-slots answer for 
powder-blasts discharged beneath the plants. See PI. XXVII, Fig. 4, ss.
