uid on a large scale, whether patented or not. 

 are modifications of one and the same idea and 

 principle, viz., a barrel or other vessel to contain 

 the liquid, a vehicle to carry it, a force-pump 

 firmly secured to the top of the barrel, and a dis- 

 tributing nozzle, or several of them, connected 

 with the discharge-pipe. The differences they 

 exhibit are found principally in the nature of the 

 distributors, the most successful ones being those 

 which least clog, since it is almost impossible to 

 get such pure water that there will not be some 

 clogging material, even where strainers are used. 



"The Goodin Sprinkler. — This machine, in- 

 vented by Mr. James L. Goodin, of Montgomery, 

 Te.\. (patent No. ig8,oi4, December 11, 1877), is 

 represented by the accompanying cuts. Fig. 88 

 is a top view, and Fig. 8g a side view of the same. 

 The letter A represents a tank or any other vessel 

 to receive the poisoned liquid.

" In the lower part of the forward end of the tank A is se- 

 cured a discharge-pipe, E, the inner end of which is provided 

 with a valve or ordinary syrup-faucet. The stem C of the 

 valve or faucet passes up through a hole in the top of the 

 tank A, and its upper end is pivoted to the end of a lever, D, 

 which is pivoted to a short standard, E, attached to the top of 

 the tank A.

The Gocdin S 



of the pump-cylinder is left open and a spout or tube, J, is 

 connected thereto to conduct the liquid, which would other- 

 wise be wasted, back into the barrel. 



"The connection of this waste-pipe with this ma- 

 chine is the only point which is claimed as new 

 by the inventor. The sprinklers or nozzles are

" To the forward end of the pipe B is attached a cross-pipe, 

 ¥, from the forward side of the center and ends of which pro- 

 ject short pipes, G, having heads, H, attached to their forward 

 ends. The heads Hare perforated with numerous small holes. 

 The pipes B F are jointed as shown in the drawing, so that 

 they may be lengthened or shortened as circumstances may 

 require. 



*'The Yeager Si'KInkler. — This is a sprinkler 

 invented by Mr. George Yeager, of Flatonia, 

 Tex. (patent No. 204,410, May 28, 1878). Fig. 90 

 is a part sectional side view, and Fig. gi a plan 

 view thereof. 



" It consists of a platform. A, upon which is laid a barrel, B. 

 containing the poisonous liquid. A rubber hose, C, connects 

 this barrel with the bottom of a pump-cylinder, D, This cyl- 

 inder is supported on a step. A', and its upper end held in a 

 brace, A2, attached to a standard, A^, which rises from the 

 platform A. E is the pump-plunger, connected to a lever, F, 

 which is pivoted in the upper end of the standard A3. The 

 liquid poison is forced out through the sprinklers G G (i, 

 which are three in number, and throw the water in a fine inisi 

 over three rows of cotton. A rubber hose, I, is attached to 

 each of the spouts H of the pump to form connection with 

 the sprinklers G, for the purpose of lengthening or shortening 

 the spouts, especially the two on opposite sides of the pump, 

 arid of detaching and cleaning the sprinklers. The upper end

"The RiTHM.\NN Sprinicler. — Invented by Mr. 

 Julius P. Ruhmann, of Schiilenburg, Te.\. (pat- 

 ent No. 206,901 August 13, 1878.) This does not 

 differ in any essential respect from the machines 

 just described.
