JAMES HIRAM LEMONS, OF CEDAR HILL, TENNESSEE, ASSIGNOR T0 3'. S. ADAMS 0F CEDAR HILL, TENNESSEE.

POWDER-GUN.

T0 allwhom it may concern:

Be it known that I, JAMES H. LEMONS, a citizen of the United States, residing at Cedar Hill, in the county of Robertson and State of Tennessee, have invented certain new and useful Improvements in Powder- Guns, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in powder guns and has relation more particularly to a device of this general character especially designed and adapted for use in the spraying of plants with insecticides, and it is an object of the invention to provide a novel and improved device of this general character including means whereby the requisite discharge of the powder is obtained through the medium of an air current.

Another object of the invention is to provide a novel andimproved device of this general character including a reservoir with which communicates a delivery pipe, together with a fan coacting with said pipe in a manner to withdraw the powder by suction from within the reservoir and which fan also operates to provide an eifective distribution of the powder as the same is discharged.

It is also an object of the invention to provide a novel and improved device wherein the parts are assembled in a manner to permit the same to be readily carried by the operator with convenience and facility.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved powder gun whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view, partly in longitudinal section and partly in elevation, of a powder gun constructed in accordance with an embodiment of my invention.

Specification of Letters Patent.

Patented Feb. 10, 1920.

Application filed May 14, 1919. Serial No. 297,005.

Fig. 2 is a fragmentary sectional view taken substantially on the line 22 of Fig.1.

Fig. 3 is a sectional view taken substantially on the line 83 of Fig. 2, and

Fig. 4 is a sectional view taken substantially on the line 44 of Fig. 1.

As disclosed in the accompanying drawings, R denotes a reservoir herein disclosed as substantially cylindrical in form and which is provided in its side wall with a filling opening 1 normally closed by the cap or plug 2? At a point substantially diametrically opposed to the opening 1, the side wall of the reservoir R is provided with a second opening 3 in communication with an end portion of a suction pipe 4. The reservoir R and pipe 4 are secured one to the other and preferably through the medium of the attaching plates 5.

The opposite end portion of the pipe 4 is secured to the fan casing C at a point eccentric to its axial center and which casing has its opposed flat faces disposed on an angle of substantially forty-five degrees relative to the axis of the pipe 4 and inclined inwardly of the pipe 4 at the side thereof at which the reservoir R is arranged. The peripheral portion of the casing C is provided with a substantially tangentially arranged discharge nozzle "6- and the inner end portion of said nozzle 6 gradually merges into the casing C proper so that the material which is drawn from the reservoir R throughthe pipe 4 by the fan blades B passes through the path of travel of said blades before discharging through the nozzle 6, whereby the discharge of said material is in a condition to obtain an effective deposit upon the plants or the like to be treated.

The. outer face of the casing O is provided with an outstanding bearing 7 through which is directed a shaft 8. The shaft 8 extends within the casing C and the inner end portion. thereof is rotatably supported by a bearing 9 carried by the inwardly converging arms 10 suitably secured to said outer face of the casing C. The shaft 8 extends inwardly beyond the bearing 9 and radiating from said inner or extended portion are the shanks 11 of the blades B. r

v The outer end portion of the shaft 8 has fixed thereto a friction wheel 12 which is engaged'with the face of the driving wheel 14. The driving wheel 14 is fixed to a shaft 15 rotatably supported by the outstanding bracket 16 carried by the outer face of the casing C. The shaft 15 also has engaged therewith an operating crank 17 whereby the requisite rotation may be imparted to the wheel 14 for driving the fan.

The end portion of the pipe 4 adjacent the reservoir R is open so that upon operation of the fan, the desired suction is creatcd therethrough. In order to control the feed ing of the material from the reservoir R into the pipe 4, a rotatable sleeve or valve 18 is snugly fitted within the open end portion of the pipe 4 and is provided in the wall thereof with an opening 19 adapted to register with the opening 3 in the wall of the reservoir R. By properly rotating the sleeve 18, the opening 3 may be completely closed or opened as desired. To facilitate the desired rotation of the slee ve 18, the outer end portion thereof is provided with the intersecting and radially directed rod 1 or member 20.

The outer face of the casing G is provided with a radially disposed tube or conduit 21 in communication with the bearing 7 to provide means whereby the shaft 8 may be conveniently lubricated. The tube or conduit 21 extends in substantially the same general direction relative to the pipe 4 as the reservoir R.

Supported by the inner face of the reservoir R and a peripheral portion of the casmg C is an elongated tube 22 substantially in parallelism with the pipe 4 and terminating outwardly of the casing C. Disposed through the tube 22 is a shaft 23. The shaft 23 extends within the reservoir R and is continued by a lateral extension or arm 24 whereby the contents of the reservoir R are effectively agitated upon rotation of the shaft 23.

The shaft 23 also extends beyond the outer end of the tube 22 and secured to this extended portion is a friction disk 25 in contact with the wheel 14, whereby said shaft 23 is rotated by the wheel 14 in unison with the shaft 8.

The opening 3 has disposed thereacross a screening element 26, herein disclosed as a reticulated fabric, and which element serves to prevent the passage through the opening 3 of material which is not comminuted.

In practice, it is preferred that a suitable body harness be engaged with my improved device, but as this harness forms no part of my present invention, a description and illustration thereof are believed to be unnecessary.

In use, it is also preferred that the device he supported by the left side of the operator with the pipe 4 substantially horizontally disposed and the reservoir R extending upwardly at a position at the rear. When so arranged, the crank 17 may be conveniently operated. This positioning of the device results in the same being well balanced and with a minimum of strain on the operator.

My improved gun is primarily intended for use to spray or distribute insecticides upon plants or the like, but it is to be understood that the same can be employed in connection with other material and for other purposes as the necessities of practice may require.

From the foregoing description, it is thought to be obvious that a powder gun constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the. several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. A gun of the class described comprising a fan casing having a discharge nozzle in connection with its peripheral portion, fan blades rotatably supported within the casing, means for rotating the fan blades, a suction pipe connected to the casing and in communication therewith through a side wall thereof, the opposite end portion of the pipe being open, a reservoir supported by the open end portion of the suction pipe and at one side thereof, said reservoir being in communication with the suction pipe, an elongated member supported by the reservoir and casing, said member being substantially in parallelism with the suction pipe and spaced therefrom, said member being tubular, a' shaft extending through said tubular member, and an agitating arm within the reservoir and carried by the shaft, said shaft being in driven connection with the means for rotating the fan blades.

2. A powder gun adapted to be supported by the operator and comprising a casing provided with a discharge in communication with the peripheral portion of the casing, fan blades rotatably supported within 120 the casing, a suction pipe in communication with the casing through a side wall thereof, and at a point inwardly of the blades, said suction pipe being also in communication with the atmosphere, a reservoir mounted 125 upon said suction pipe and in communication therewith at a point inwardly of the communication of the suction pipe with the atmosphere, and means carried by the cas ing for rotating the fan blades.

3. A powder gun adapted to be supported by the operator and comprising a casing provided with a discharge in communication with the peripheral portion of the casing, fan blades rotatably supported within the casing, a suction pipe in communication with the casing through a side wall thereof, and at a point inwardly of theblades, said suction pipe being also in communication with the atmosphere, areservoir mounted upon said suction pipe and in communication therewith at a point inwardly of the communication of the suction pipe with the atmosphere, means carried by the casing for rotating the fan blades, a member connect- 51 ing the fan casing and the reservoir, and a shaft disposed through said member and. provided with an agitating arm arranged within the reservoir, said shaft being in driven connection with the means for ro- 20 tating the fan blades.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
