IMPROVEMENT IN- PowD'ER-EJEcToRs.

Specitication forming part of 'Letters Patent No. 176,279, dated April 18, 1876; application filed February 24, 1876.

To all whom it may concern:

Be itknown that I, CHARLES GnINNoox, of Brooklyn, in the county ot Kings and State of New York, have invented certain new and useful Improvements in Powder-Ejector, of which the following is a specification:

This invention relates to an improved injector or powderfgun, for throwing obnoxious or poisonous powders into or upon places oecupied by insects, for destruction and extermination of the same; its object being to provide an apparatus that can be cheaply constructed, and that can be conveniently lled and handled, and in which the contents 'are in full view of the operator, in order to indicate when it is necessary to replenish the ap paratus.

The invention consists ot' a ask or other suitably shaped receptacle, constructed of glass or other suitable material, and provided withan open mouth and bottom, the mouth being adapted to receive a cap or stopper,

provided with a discharge-tube, having' a ilexible-jointed extension projecting into the interior of the receptacle, and the open bottom being provided with a flexible bottom, distended from the inside by means of a spiral or other spring. The inner ilexible end of the discharge-tube is adapted to fall to the lower side of the receptacle in whatever position the flask may be held, in order to provide for the discharge of the last portions of the contents of the ask, and is made in sections, jointed together, in order to enable it to be shortened or lengthened as the bottle is tilled and emptied, so that it may be properly inserted and will always fall in proper position. The exible bottom may be made removable, in order to allow the flask to be Iilled from the bottom 5.

or it may be permanently attached to the flask, the ask being formed with an external groove around its lower edge, in which the bottom may be secured by means of al1 elastic band of rubber, metal, or other material, or by a binding cord or wire Otl any suitable-material.

In the drawing, Figure 1 represents a per- .spective View of my apparatus, and. Fig. 2 a

sectional view ot' the same. v

The letter A represents a flask or other shaped receptacle for the powder,constructed open mouth and bottom. B represents a stopper or cap, adapted to it into or be otherwise secured to the mouth of the flask. C represents a disehargetube, extending through the stopper or cap, and provided at its inner end with a iiexible tube or extension, D, formed in sections, which are jointed together in such manner that the sections may be separated and thetube shortened, as desired.

The object of such construction of the ilexible extension is to enable the same to be shortened, as desired, when the flask is filled through the mouth, so as to enable the cap and tube to be inserted when the bottle is completely filled, and to be extended as the flask becomes empty.

Around the exterior of the edge of the open mouth of the flask is formed a groove or annular recess, E, for the purpose ot' receiving and holding the edge ofthe liexible bottom F. Said bottom is composed of exible cup or disk, ot rubber, oiled silk, or other suitable material, secured or bound into the groove or recess E by means of an elastic or detachable band of rubber, metal, or other suitable material, or by a permanent binding cord or wire of any suitable material.

G represents a spiral spring sitting within the flask, its upper end having a bearing against the interior of the shoulder of the ilask, and its lower end against a rigid disk, H, of metal or other material, sitting against the flexible bottom F.

The object of said spring is to keep the tlexible bottom distended outwardly, and allow it to be pressed inwardly to discharge the powder.

As thus constructed, it will be seen that the powder can always be discharged as long as any remains in the ilask, as the end of the flexible extension of the discharge-tube always lies at the lowest part of the ilask in whatever position it may be turned.

'By constructing the flexible connection in sections, provision is made for the insertion of the top and tlexible extension in the ask, and providing for the thorough discharge of the powder whether the flask is full or partially full, and by means of the iexible bottom a convenient means of discharging the powder is obtained.

vided with a exible sectional discharge-tube, D, the whole being constructed and arranged substantiali y as described, for the object specified. Y

In testimony that I claim the foregoing I have hereunto set my handin the presence of the subscribing witnesses.
