same as that described on page 196. Mr. Melcher, who is an inventor 
of various contrivances, strongly recommended his pump to the public. 
His nozzles are much used and are still made by him and by others. 
The Charles Vogelsang Spray-pump for Poisoning on Cotton. — Mr, 
Charles Vogelsang, of Bound Top, Fayette County, Texas, patented, 
in No. 194388, August 21, 1877, a sprinkling pump with nozzles as 
shown in 1'latc XLI I, Figs. 5, (J, 7, and S. The T-handled, solid plunger, 
/*, works in a thin cylinder having a basal suction-strainer, a, and valve, 
with basal discharge-valve, air-chamber, </, and spoilt, e. The spoilt, 
e, chamber, <1, and cylinder, Z>, are about equal in length and joined to- 
gether compactly side by side, the spoilt having a crook at its top on 
which various nozzles may be used. In his letters patent are figured 
and described the concave and scoop-shaped spray detlectors and quad- 
rant shaped and circular nozzles with many -punctured periphery. 
Another pump of the same type and embracing some of the details 
of the two just noticed, with some additional peculiarities of little value, 
is that made by Mr. Kallmann. 
" The Kuhmann Sprinkler. — Invented by Mr. Julius P. Kuhmann, of 
Schulenburg, Tex. (patent No. L'OGOOl, August 13, 1878.)" 
In Plate XLIV, Fig. ."> is a longitudinal section of the machine; Fig. 
4 shows the connection of the pump-cylinder with the air-chamber ; 
Pig. 6 represents the strainer: Plate XV, Figs. (> and 7, the nozzle, 
showing the arrangement for cleaning the same; and Plate XLIV, Fig. 
show s a modification of the discharge-pipe. 
"The letter a represents the reservoir for holding the poisonous 
liquid ; b is the pump-cylinder, in which the piston, c, is worked up and 
down by means of the lever, d. The lower end of t his cylinder is made 
funnel shapped, and to it is fastened the rubber tube. <, which connects 
it with the strainer,/. This strainer is made in two parts for the intro- 
duction of a straining-cloth, g, and for convenience in cleaning. The 
lower end of the strainer is perforated, and, if desired, any additional 
straining matter may be placed between the perforated bottom and the 
cloth, so as to make sure that no substances shall be forced into the 
sprinkler to clog its action. To the lower end of the cylinder is secured 
the discharge pipe, //, upon the top of which is formed the air chamber, 
t. Upon the outer end of the discharge-pipe is placed the sprinkler, ?, 
which is round and flat, as shown, and perforated about one-half around. 
Upon the top of this sprinkler is screwed the cap or cover, w, secured 
to which is the brush, n. The handle of the brush is bent at right 
angles, as shown, and is secured to the cap in such a maimer as to form, 
as it were, a part thereof, so that as the brush is moved around to clear 
away any obstructions which may have a tendency to close up the line 
perforations in the edgeof the sprinkler the cap turns with it. By 
means of this screw-cap the brush can be adjusted up and down at will, 
so that after cleaning off the perforations the brush can bo depressed 
down below the level of the holes, so as to be out of the way."
