Description
E. JOHNSON POWDER SPRAYER Filed Feb. 28.
June 26, 1923.
Patented June 26, 1923 ELMER JOHNSON, OF WASHINGTON, DISTRICT OF COLUMBIA; DEDICATED, BY MESNE ASSIGNMENTS, TO THE PEOPLE OF THE UNITED STATES.
POWDER SPRAYER.
Application filed February 28, 1923. Serial No. 621,876.
(TILED UNDER THE ACT OF MARCH 3, 1888, 22 STAT. II-, 625.)
To all whom it may concern:
Be it known that I, ELMER JOHNSON, a citizen of the United States of America, and an employee of the Department of Agriculture of the United States of America, residing at Washington, District of Columbia, whose post-office address is care of United States Department of Agriculture, Washington, D. 0., have invented a Powder Sprayer.
This application is made under the act of March 3, 1883, chapter 143 (22 Stat. 625) and the invention herein described and claimed may be used by the Government of the United States or any of its ofiicers or employees in the prosecution of work for the Government, or any person in the United States, without payment to me of any royalty thereon.
Referring to the drawing, the sole figure shows a side elevation of the invention.
The device. shown in the drawing consists of a hopper 1, into which is put the insect-icide intended for use in spraying cotton to combat the boll weevil, said hopper being )IOVldGd with a cover 16, a valve 2 for closing the bottom 12 of the hopper 1, said valve also being adapted to be moved in an upward direction, the upper portion thereof forming contact with air intake tube 3. This tube 3 has air tubes 4 the function of which is to furnish air to the interior of the hopper 1 to agitate the insecticide contained therein, and also has at its upper end, which extends outside the hopper 1, a funnel 17, for collecting air for the main air line, when used on an airplane. Slots 5 in the upper part of valve 2 coincides with openings 13 extendin from air intake tube 3 to agitator or air tu es 4:. The device also has an outlet or discharge tube 6 at the bottom of the hopper 1.
A rod 7 is affixed to the bottom of valve 2 by means of a cross bar 11, the rod 7 passing through discharge tube 6, and the lower end of said rod is affixed to a rocking lever 8 at the left hand end of which lever 8 is afiixed a handle 10 adapted for raising and lowering said rocking lever, and at the center of said lever is a bracket 9 for carrying said lever. The device is attached to the frame of the vehicle on which it is intended to be used, in an suitable manner.
he operation of the device is as follows:
A current of air is forced through pipe 3,
and discharged at the lower end of tube or the valve or nozzle 2 and the valve seat 12 through which the insecticide, or other material in the hopper, is free to flow and be caught in the air current passing through valve or nozzle-2 and be delivered into the air. Coincident with raising the valve 2, the openings 5 are raised to a point where they coincide with openings 13 leading to tubes 4 and permit a certain amount of air to pass through and be discharged into the hopper through the ends of tubes Land in a direction to carry any dust caught in the current through the valve opening.
For any setting of the valve the quantity of dust fed through depends on the velocity of the air current flowing through the valve and nozzle 2, the theory being that the high velocity current in passing out through t e enlarged opening at the bottom of valve 2 tends to create a vacuum around the valve and pulls the dust or material down into the air stream and is ejected through discharge 6. If necessary tube 6 can have branches leading from it to desired points.
I claim:
In a dusting machine, a hopper containing insecticide, a tube leading from said hopper, pipes leading inside said hopper from said tube, afunnel at the top of said tube for introducing air into said tube and said pipes, an outlet in said hopper, and a valve controlling said outlet for distributing insecticide from the hopper to be mixed with the air introduced into said tube.
Ear/ma JOHNSON.
