tion of structure, expensiveness, and also some other features which 

 have prevented it from coming into the market. It is an early attempt 

 to introduce air-pumps and air-pressure in cotton- worm destroj^ers. 



A pair of air-pumps are used, but nothing new is claimed for their 

 construction. The arrangement for producing the spray is the old- 

 fashioned gas jet, which was also patented in 1878 by Mr. Adolph 

 Weber, of Detroit, Mich., as a nose-piece for spraying water. The 

 nozzle is presented in Plate XV, Fig. 5, and its description. 



The following appeared in the first edition of this work, concerning 

 Mr. Daughtrey^s invention : 



"The Daughtrey Atomizer. — There still remains one machine 

 to be described in this connection which is highly interesting for several 

 reasons : 1st, because it is the only one actually in use for the distrib- 

 uting of the liquid from below; 2d, because the construction of the 

 pump is quite peculiar; and, 3d, because the arrangement for produc- 

 ing the spray is not only entirely different from any described in the 

 foregoing pages, but also most simple. This machine was invented by 

 Mr. William J. Daughtrey, of Selma, Ala. (patent IN'o. 200376, February 

 19, 1878). The accompanying sketch (Plate XXXYI) represents it as 

 it appears. It consists in the main of a pump, which is made self-op- 

 erating by means of a pulley, and which forces air into the receiving 

 tank and into a compression cylinder connected therewith, thus supplj^- 

 ing the pressure necessary for the production of the spray. As will be 

 seen from the sketch, a transverse distributing jMpe is connected with 

 a number (four in the sketch) of vertical pipes recurved at the ends, 

 which receives the nozzles, one of which is represented in section in 

 Plate XXXYII, Fig. 5. The nozzle. X, which is screwed onto the pipe, 

 has a closed end, n^ provided with two openings, ti', oppositely inclined, 

 so that the jets delivered through them meet at a i)oint near n and de- 

 flect and disperse each other so as to form an extremely fine spray. 

 The openings, %\ are large enough to avoid being obstructed b^? small 

 obstacles, and the spray produced by the two inclined jets is at once 

 copious and powerful. 



" The following is a more detailed description of the machine, very 

 much in the inventor's own words, Plate XXXYII, Fig. 9, being a ver- 

 tical section and Plate XXXYII, Fig. 3, a detailed view of the axle- 

 tree, showing the parts connected therewith in section : 



" In the drawings A represents the frame of a vehicle, B B the wheels, and C C^ the 

 two axles constituting the axletree, which have their bearings, c, fastened below the 

 frame, A. Between the bearings, c, the axles, C C^ are provided with shoulders, c', 

 whereby they are prevented from parting with each other longitudinally, while a 

 socket, c^, at the inner end of the axle, CS incloses the inner end of the axle, C, and 

 thereby prevents both axles from moving out of line. The two said axles may be 

 coupled by means of a pin, c^, inserted into the socket, c", and axle, C, but usually it is 

 omitted, and the axles, C C^, are allowed to revolve independently of each other. The 

 hubs, b, of the wheels, B B, are provided with set-screws, ¥, or coupling-pins, J^, or with 

 both, in order to fasten them to the axles, C C. The use of the set-screw, ¥, and pin, 6*,
