CONDUITS, PORTAGE, ETC. 287 



"To the tank, A, is attached a suitable pump, C, the piston, a, thereof haviug con- 

 nected to its upper end a link, h, iivhich, in turn, is connected to an arm, c, pivoted to 

 the upper end of a standard, d, rigidly secured to the top of the tank. 



"To the outer end of the arm c is pivoted a rod, e, its lower end being connected to 

 a crank, /, vrhich has its bearings in the side of the tank, A, and grooved pulley, D, 

 The crank,/, is made to engage with the grooved pulley, D, in such manner as will 

 cause the crank to revolve by the rotation of the pulley. This I accomplish by 

 the employment of the ordinary clutch, g, the two sections thereof being made to en- 

 gage with each other by the lever,/*, which is connected thereto, or be disengaged 

 when the pump is not required to bo operated. 



"The grooved pulley, D, is supported by a suitable bracket, j, connected to the side 

 of the tank. A, Avliile the lower grooved pulley, E, is rigidly secured to the inner hide 

 of the wheel carriage or truck, so that it will revolve with it. A belt or chain, i, 

 passes over the two pulleys, D E, by which motion is communicated to the upper 

 pulley when the carriage or truck is in motion. 



"Connected to the pump, C, is a horizontal pipe, F, to the end of which are suitable 

 faucets, A", to control the flow of liquid to the sprinkling pipes, these faucets being of 

 any suitable construction found best adapted to the purpose. 



"To the horizontal pipe, F, is connected a suitable number of pipes, G, extending 

 down near the ground, and provided at their lower ends with rose-heads, H, each of 

 which has removable screw plugs, I, to admit of their being cleaned Avhen required. 

 These pipes, G, are connected to the horizontal pipe, F, by unions or coupling sections, 

 or any other desirable means may be employed. The outer pipes, however, I connect 

 to the pipe, F, by the addition of short sections, m, of pipe, although I do not desire 

 to confine myself to any special means employed. The pipes, G, are raised to the re- 

 quired height from the ground, and 1-y a suitable lifting device, consisting of the 

 horizontal supporting arm, I, formed in sections and hinged together, so that when 

 opened and extended they form a continuous horizontal arm, against which the pipes, 

 G, rest. 



"To the supporting arm, I, is connected a curved rod, n, pivoted to the side of the 

 tank, A, and having connected to it a pivoted arm, o, to which the operating lever, Ji, 

 is secured, by means of which the supporting arm, I, may be raised or lowered as cir- 

 cumstances require. This supporting arm or carrier, I, has semicircular seats, jj, to 

 receive the pipes, G, and bob! tbem in an upright position. The object of forming the 

 arm or carrier, I, in sections and hinging them together is to i educe the length of the 

 same, so as to enable the folding of the i)ipes from both sides of the caiTiage or truck 

 when not required for use. 



"The rose-heads, H, are preferably formed with rows, 1, 2, 3, 4, 5, and 6, extending 

 lengthwise and up the sides of said rose-heads, so that the plants will be sprinkled 

 above and beneath the leaves. 



"The unions of the several sections of pipes admit of their being folded conveniently 

 together, so as to admit of their being transi^orted with ease and without incum- 

 brance. 



"The machine will sprinkle as many rows of cotton as there are pipes, G, they being 

 the required distance apart to correspond to the distance between the rows, the hinged 

 sections of the supporting arms or carriers being opened and extended in accordance 

 with the number o'f pipes, G, that are used." 



This macbiue possesses certain points of special interest. The 

 wheeled reservoir and pumping arrangement is strongly similar to 

 what appeared in Mr. Johnson's machine, described above, as shown 

 in Plate LIII and Plate LIV, Figs. 1 and 2. The plan of a main 

 T-pipe, forming extended arms with backward and downward branches 

 for carrying nozzles, is also an old feature, occurring in modified forms
