To all lwhom t may concern: disk 5 is imperforate, as shown best in Fig- Be it known that I, SAMUEL BERNSTEIN, ure 3, so that when the gun is not vin use a citizen of the United States, and resident the valve portion 9 prevents powder from of New York, in the county and State of passing into the bulb from the container l,

This invention relates to powder guns When the bulb is compressed, as shown in l0 designed for discharging insect powder, and Figure 2, the air discharged therefrom raises @5 it has for its object to provide an improved the valve flange 9 away from the perderadevice of this kind having a powder-oon tions in the disk 5, thus allowing said air to taining body, a'nozzle at one end of said' enter the container and act upon the powder body through which the powder is distherein to eject it through the nozzle 3 at charged, and a bellows attached to the other the other end of said container.
