' sraarma DEVICE.

Application filed April 22, 1920. Serial No. 375,761.

To all whom it may concern:

Be it known that I, J OSEPH F. LEMONS, a

Cedar Hill, in the county of Robertson and State of Tennessee, have invented a certain I in Spraying Devices, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings.

This invention relates to spraylng devices and more particularly to portable devices of this character WhlCll are used for distributing pulverulent material for the purpose of destroying insects and undesirable growths on trees, plants and other vegetable life.

Some of the objects of the present invention are to provide a device of this character which shall be so constructed as to permit the center of gravity thereof to be adjacent the operator, so as to afl'ord perfect balance and ease of manipulation; to provide a de-. vice of this character which shall draw the pulverized material into contact with the revolving fan before discharging said powder, thereby securin a uniform dist 'bution of finely divide material; to provide a device of this character which shall be simple in construction and inexpensiveto manufacture, while further objects and advantages will appear as the description proceeds;

Inthe accompanying drawin wherein I have shown an illustrative em odiment of my. invention, but without intent to limit myself thereto, Fig. 1 is a perspective view a position ready for operation; Fig. 2 is a top plan view thereof; and Figs. 3 and 4 are sectional views taken on the lines 33 and 4-4, respectively, of

Fig. 2.

escribing the various parts by reference characters, 1 indicates a suitable reservoir which is provided at the top thereof with a filling opening 2 which is normally closed by a detachable cover 3. The reservoir 1 is secured to the top cylindrical wall of the rear or open end of a suction pipe '4, and braced thereon by the straps 5-5., An opening 6 communicates with the interior of the suction pipe 4 and the interior of the reservoir 1, the effective size of said opening being varied by means of a rotatable sleeve member 7 which is provided with a slotted opening 8 that may be brought into alignment with the opening 6 by grasping the rear end of said sleeve and rotating it through the desired angle.- An elbow 10 is secured to the forward end of the suction pipe 4 and said elbow communicates with the interior of the vertical fan casing 11 in axial alignment with the fan member 12. The fan member is mounted on a shaft 14, journaled in a strap 15 which extends diametrically across one side of the casing 11 and projects on the forward side thereof as indicated at 16. A small ar 17 is mounted on the outer end of said s aft, intermediate said strap, and a bracket 18, which is, fastened to said strap. A second strap 20 is fastened on the opposite side of said casing substantially parallel to the pipe 4 and in such position as to project on the forward side of the casing in transverse alignment with the projection 16. Atransverse shaft 21 is journaled in said projections and mounts at one end thereof a drive gear 22 and an operating crank 23, and at the other end a bevel gear-24. A small intermediate gear 25 and a larger gear 26 are fastened together and 'ournaled on a stud shaft mounted on t e strap 15, said gears being meshed respectively with the drive gear 22 and the fan gear 20 so that b slowly turning the operating crank 23 t e fan will be caused to rotate rapidly and produce a suction in pipe 4 and divert the blast through the discharge nozzle 27 at the top peripheral portion of the fan casin The strapv20 has pre erablyformed integral therewith the spaced lugs 2828 which rotatabl support the forward end of a shaft 29 whic extends rearwardly throu h a bearing plate 30 and into reservoir 1. The forward end of said shaft is fitted with a beveled gear 31' which meshes with the beveled car 24. The rear end of said shaft is provi ed with a brush 32 and the agitating members 33-33 positioned on each side thereof, together shaft. bring its lower portion in position tosweep over the outlet opening 6, thereby assuring a positive feed of the powder while the rota a 'tating membersserve to feed the pow er into contact with the brush.

In operation, the reservoir 1 is filled with the powder to be sprayed, such as arsenate said parts being securel clamped by the nuts 34-34 threa ed on the The brush is of such diameter as-to of lead, and the device swung from the side of the operator by the strap 35 which is passed over his shoulder and fastened to each end of the device as illustrated in Fig. 1. It will be noted that the reservoir is positioned at the rear, and the fan casing at the front of the operator, so that the center of gravity of the machine is close to the operators body which permits balance of the device and easy carrying and operating thereof. By turning the crank 23, the fan 12 is caused to rotate rapidly, thereby pro ducing a suction draft through pipe 4, and simultaneously rotating the brush 32 and agitators 3333, to feed the finely divided powder through openings 6 and 8 in a quantity determined by the position of the rotatable sleeve member 7. The powder is carried forward by the suction draft into the fan casing, and into contact with the revolving fan where any lumps are broken up which might have been drawn therein.

. The pulverized material is then blown through the discharge nozzle 27 and through any suitable detachable directing devices such as indicated at 36 and 37.

The operator will be advised when the reservoir. is about empty by the downward tipping of the forward end of the device and thus refilling of the reservoir can be accomplished before starting off on another expedition and the operator is aware at all times of the approximate quantity of the material at hand.

Having thus described my invention, what I claim is 1. A portable device of the class described comprislng a casing having an inlet and a discharge opening, a fan member journaled 1n said casing, means for rotating said fan member, a reservoir, a pipe connecting said reservoir and one of said openings, and means for suspending said device from the operator whereb the weight of said device will be positioned forwardly and the other half rearwardly of the operator.
