Eydropults and Hydronettes. 



These, as the names imply, are contri- 

 vances for drawing into a pipe water con- 

 tained in a pail or any similar receptacle, 

 and driving it out with force to a consider- 

 able distance. Like the syringe, the 

 simplest and cheapest form of this appli- 

 ance is made in zinc. There is a vertical 

 pipe, like the tube of a syringe, which is 

 placed in water; at the lower end is a 

 valve through which the water is drawn 

 into the pipe by the upward action of the 

 piston, which in itself also resembles the 

 piston and rod of the syringe. When the 

 piston is pressed downward the valve at 

 the bottom is closed, and the water is 

 driven upward through a smaller tube at 

 the side of the larger one, terminating in a 

 spreader, which is flat in form and bent 



slightly outwards, so that water may be 

 thrown against any object towards which 

 the spreader is directed, and to some height. 

 They are made in different sizes, as are 

 also the patent hydronettes, which throw a 

 stream of water to distances varying from 

 30 to 60 feet, and are supplied in four sizes, 

 namely, No. I, 20 inches long; No. 2, 24 

 inches; No. 3, 28 inches; and No. 4, 31 

 inches. Warner's Patent Aquaject, shown 

 in the accompanying illustration, is a similar 

 contrivance. Above a cast-iron stand, on 

 which it is supported, rises an egg-shaped 

 receptacle, upon which is a vertical tube, 

 in which works a piston, surmounted by a 

 horizontal D handle. A flexible pipe ol 

 some length, through which water is drawn 

 into the receptacle by the action of the 

 piston, enters the upper part of this cavity ; 

 and attached to the main pipe is another 

 tube, also flexible, and terminating in a 

 spreader, through which the water is 

 ejected.
