2 Claims.

This invention appertains to new and useful improvements in mechanism for spreading soda as a fertilizer for plants and other growths.

This is a division of my co-pending application Serial No. 60,293, filed January 22, 1936.

The principal object of the invention is to provide a dispenser of the character stated which can be conveniently carried about by the work man and from which the soda can be dispensed in an easy and eflicient manner.

Other objects and advantages reside in the positive acting mechanical parts, the compactness of construction and the fact that the same is not susceptible to the ready development of defects.

In the drawing:-

Figure 1 is a vertical sectional view through the device.

Figure 2 is a cross-sectional View taken substantially on the line 2-2 of Figure 1.

Figure 3 is a cross-sectional view on the line 3-3 of Figure 1.

Referring to the drawing wherein like numerals designate like parts, it can be seen that reference character 5w represents the barrel and reference character To the cone which is provided with the threaded tubular extension disposed into the internally threaded neck 8a of the conical-shaped nozzle 9a. The shell 5a is provided with ears 24a for a shoulder-engaging strap and disposed into the upper end of the shell 5a is the top I 4a upon which is the upright 25 to which the arm 26 is pivotally secured as at 21. Numeral 28 is an upstanding guide on the top Ma against which the arm 26 can ride and which can serve as a stop to limit the rise of the arm 26. This arm 26 is provided with a handle 29.

Numeral 30 represents the vertically extending shaft, the upper end of which is provided with the screw 30a threaded through the plate 3| on the block 32 carried by, the top Ma; A cross pin 3211. on the shaft 30 limits the rise of the shaft 30, while the upper end of the shaft '30 is engaged into a groove in the bottom of the arm 26.

A U-shaped bearing 33 has its upper end provided with ears which are secured by screws 34 to the underside of the top Ma. Sideplates'35 are placed against opposite open sides of the U-shaped bearing 33 and screws 36 are disposed through this bearing for connecting these plates 35 in clamping engagement against opposite sides of the bearing l3. A collar-31 on the shaft 30 above the bight portion on the bearing 33 is prevented from rising by the cross pin 38 and a coiled compressible spring 39 is interposed beapplication April 19,

tween the bight portion of the bearing 33 and the said collar 3'! for normally urging the shaft 30 to an upward position, maintaining the conicalshaped plug 40 engaged in the lower end of the cone la.

The U-shaped bearing 33 in conjunction with the side plates 35-35 forms a box in which 1ubricant is retained and from which the same cannot escape into the shell 5a or cone 1a. Numeral 4| is a small tube extending through the block 10 20 Obviously, when the handle 29 is forced downwardly, the arm 26 would effect the longitudinal downward movement of the shaft 30. As the screw 38 passes through the plate 3|, the shaft is rotated and against the tension of the spring 39 the plug 43 is displaced from the lower end of the cone 1a, thus permitting the material below the agitator to be shot out into the nozzle 9a and from the nozzle to it end. I e 0 While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as 35 claimed hereinafter.

Having described the claimed as new is:-

1. A dispenserof the character described comprising a hopper provided with a tapering bot- 40 tom, a vertically movable shaft in the hopper and extending through the bottom thereof, means at the upper end of the hopper for operating the said shaft, the lower portion of the shaft being point distant from its discharge invention, what is provided with threads, a valve element feedable 45 on the threaded portion of the shaft, a nut for holding'the valve element against self adjusting, an agitator disposed on the threaded portion of I the shaft, and a jam nut on the threaded portion of the shaft at each side of the said agitating member to prevent self adjusting of the agitating member. 7

2. A dispenser of the character described comprising a hopper having. a discharge opening in the bottom thereof, a vertical shaft in the hop- '55 upward direction.

the spiral extension to force the same downwardly and cause rotation of the shaft, an agitating member carried by the shaft in the hopper, and spring means for returning the head shaft in an ANDRE E. CLAUDEL.
