spray. It was moved by turning some part of the nozzle which 

 was connected with the lance. The "Peerless," "Lowell," and 

 " Gem " (Fig. 18 ) are good examples of this class. 



In 1878 a patent was granted to the Belknap Company on a 

 new nozzle called the " Boss " (Fig. 18 &). It has two outlet 

 orifices, and the stream is directed into the one or the other by 

 means of a hollow stopcock which is perforated in such a man- 

 ner that it partially or entirely closes one or both of the open- 

 ings. The "Eureka," "Masson," and "Bordeaux" (Fig. 18 c) 

 are modified forms which have since appeared. The spray is 

 varied by changing the size of 

 the opening, this being easily 

 done by turning the perforated 

 stopcock. 



In 1858 Rumsey & Co. adver- 

 tised a nozzle called the "Fan- 

 tail" (see Fig. 5). It consisted 

 of a flat spreading tip having a 

 long, narrow opening which dis- 

 charged the liquid in the form 

 of a spray resembling in outline 

 the flame of a gas jet. This 

 principle of having the liquid 

 issue between two flat, parallel 

 pieces of metal has been retained 

 in more or less modified form 

 in many of the nozzles now in 

 use. One of the most primitive 

 forms was made by hammering a nozzle designed to throw a 

 solid stream in such a manner that the opening was long and 

 narrow instead of circular. It was even recommended that 

 they should be made in this manner. 1 Little was done towards 

 improving this class of nozzles until about 1889, when a patent 

 was granted on the "New Bean." In this nozzle -the width of 

 the opening could be adjusted by means of a screw, one side of 

 the orifice being of rubber packing. In 1890 Bailey published 

 a description of a device, by means of which the end of a hose 

 could be contracted so that a fan-shaped spray was produced 2
