Patented July 1'7, 1888.

(No Model.)



SPECIFICATION forming part of Letters Patent No. 386,121, dated Lay 17, 1888.

Application filed November 22, i857. Serial No. 255,856. (No model.) Patented in France April Q13, 1887, No. 1SN JTS.

.To all 2071/0797, it'may concern:

Be it known that I, CLnnnN'r GAUTHIER, a citizen of the French Republic, residing` at Marsas, in the French Republic, have invented certain new and useful Improvements in Atomizers, (for which I have obtained Letters Patent in France, dated April 23, 1887, No. 151978,) and l do hereby declare that the fo1- lowing` is a full, clear, and exact description ofthe same.

Referring to the drawings, Figure 1 is a vertical transverse section of my improved atoinizer; and Figs. 2 and 8 are horizontal and vertical sections, respectively, of the atomizmgnozzle.

The invention relates to apparatus for subdividing liquids ejected from a nozzle so as to be delivered therefrom in the form of fine spray or mist, and commonly known as atomizersfl and itrelates more especially to that class of atomizers used in spraying plants to rid them of fungi or auimaleulze, a solid being usually combined with the liquid or held in solution thereby.

One of the objects of my invention is to provide an apparatus of sufficient capacity Yfor use by gardeners either iu hot-houses or out of doors.

The invention has for its further object to provide means for preventingr the subsidence or settling of the solid matter mixed with or held in suspension in the liquid.

The further object of myinvention is to impart tothe liquid a gyratory motion in the atomiziug'nozzle, for the purpose ot' more effectually subdividing the same on issuing from said nozzle.

To these ends the invent-ion consists in structural features and combinations of parts, substantially as hereinafter fully described, and as set forth in the claims.

In the drawings, R indicates the reservoir for the liquid to be atomized, which should be sufficiently strong to resist the pressure necessary tothe ejection and atomizingoftheliquid. The reservoir is provided at its top with a charging-orifice, O, closed by a screw-plug, P', and at the bottom with a discharge-pipe, p, to which is connected a llexible tube, T, provided with the discharge-tube T. that terminates in the atomizing-nozzle N. The discharge-tube is provided with a stopcoek, t',

for obvious purposes. The nozzle N consists of a tubular couplingshank, n, adapted to be screwed into the discharge-tube T, and of a barrel, n', formed at right angles to the tubular shank, and whose inner vertical wall, n, projects across'the bore of said shank, so as to form a narrow opening or slit, if, to one side of said bore. the lower part of the bore of the barrel is enlarged and more or less spheri cal, as at n, the object of this construct-ion being to impart to the tluid a gyratory r circular motion in the barrel before said iiuid reaches the exitorifice, to more ei'feetually atomize the same by centrifugal force as it issues from the nozzle. To the upper end ot' the barrel n is screwed the perforated Cap n, the perforation if of which is made tapering inwardly.

W'ithin the reservoir R is arranged a pumpbarrel, B, in which operates a piston, l), whose rod R extends through the cap b of the barrel and is connected with a rod, r. The latter rod is connected to one arm ot' an angle or bellcrank lever, L, whose other longer arm is provided with a handle, Z, and by means of which the piston P is reciprocated in the pumpbarrel. The cap b has air-ports b', and in the piston is a val ve-easing, p, containing aspringactuated ballvalve, V, opening inwardly. Near the lower end of the pumpbarrel is formed a valved port, whose valve V opens inwardly into a valve-casing, o, to which is secured a pipe, C, provided with numerous perforations. In the end ofthe pipe leading into the valve-casing o is arranged a springactnated ball-valve, V", that also opens inwardly. By means of the pump air is forced into the receiver through the pipe C and compressed in the said receiver to the desired degree, the stopcock in the discharge pipe or tube T being of course closed during the operation of compression.

The object of forcing the air into the reservoir or receiver through a perforated pipe located nearly at the bottom thereof and extending across the reservoir is to thoroughly agitato the liquid, and thereby prevent the subsidence or settling of any solid matter held in suspension in the liquid.

A coil of pipes may be employed, ifdesired, and said perforated pipe may be dispensed with when liquids are used without an admixture of a solid or when liquids are used holding a solid in solution.

Instead ofthe ball-ValveV in the piston, any other well-known construction of valve may be employed, and instead of locating the airpump within the reservoir said pump may be attached thereto in any desired manner, or the pump may form an independent part of the reservoir.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isl v 1. In an atomizer, the combination, with a iiuid-reservoir, an atomizing-nozzle connected therewith, and a valve in the connection between the nozle and reservoir, of an air-pum p located within the reservoir, a perforated pipe arranged in the lower portion ofthe reservoir in `proximity to the bottom thereof, and com- 20 munieating at one end with the discharge-port of the pump, a back-plessu re Valve for closing the end of said perforated pipe,'and a like valve for said discharge-port of the pump, all arranged for (3o-operation substantially as and for the purpose specified.'

2. Thehereindeseribed atomizing-nozzleN, having a vertical wall or partition, n4, inter posed in its passage between its inlet and dis charge ends to form a narrow opening, n2, and the spherical enlargement n, formed in said 3o passage between the Wall vnA1 and the dischargeorifice of the nozzle, as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 31st day of 35 October, 1887.
