BARREL AND TANK SPRAY PUMPS. 275 



same as that described on page 19G. Mr. Melcher, who is an inventor 

 of various contrivances, strongly recommended his pumi) to the public. 

 His nozzles are much used and are still made by him and by others. 



The Charles Vogelsang Spray -pump for Foisoning on Cotton, — Mr. 

 Charles Vogelsang, of Eound Top, Fayette County, Texas, patented, 

 in ]S"o. 194388, August 21, 1877, a sprinkling pump with nozzles as 

 shown in Plate XLII, Figs. 5, 6, 7, and 8. The T-handled, solid plunger, 

 ^, works in a thin cylinder having a basal suction-strainer, a, and valve, 

 with basal discharge-valve, air-chamber, <Z, and spout, e. The spout, 

 Cy chamber, <Z, and cylinder, &, are about equal in length and joined to- 

 gether compactly side by side, the spout having a crook at its top on 

 which various nozzles may be used. In his letters patent are iigured 

 and described the concave and scoop-shaped spray deflectors 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. Euhmann. 



'•'• The Uuhmann Sprinl'ler. — Invented by Mr. Julius P. Euhmann, of 

 Schulenburg, Tex. (patent No. 206901, August 13, 1878.) " 



In Plate XLIV, Fig. 5 is a longitudinal section of the machine 5 Fig. 

 4 shows the connection of the pump-cylinder with the air-chamber ; 

 Fig. 6 represents the strainer ; Plate XY, Figs. 6 and 7, the nozzle, 

 showing the arrangement for cleaning the same ; and Plate XLIV, Fig. 

 3, shows a modification of the discharge-pipe. 



^'The letter a represents the reservoir for holding the poisonous 

 liquid ; & is the pump-cylinder, in which the piston, e, is worked up and 

 down by means of the lever, d. The lower end of this cylinder is made 

 funnel-shapped, and to it is fastened the rubber tube, e, which connects 

 it with the strainer, /. This strainer is made in two parts for the intro- 

 duction of a straining-cloth, ^, 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, /i, upon the top of which is formed the air chamber, 

 i. Upon the outer end of the discharge-pipe is i^laced 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, m, secured 

 to which is the brush, n. The handle of the brush is bent at right 

 angles, as shown, and is secured to the cax) in such a manner 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 fine 

 perforations in the edge of the sprinkler the cap turns with it. By 

 means of this screw-caj) the brush can be adjusted up and down at will, 

 so that after cleaning off the perforations the brush can be depressed 

 down below the level of the holes, so as to be out of the way."
