INSECT-POWDER GUN.

EEPECIl-"ICATION forming part of Letters Patent No.337,943, dated March 16,1886.

Application filed June 22, 1885. Serial No. 169,412. (No model.)

To all whom it may concern:

Be it known that we, CLARENCE A. FONER- DEN and HENRY BELL, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Insect-Powder Guns; and we do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to guns or blowers for spraying powder, and has for its object the provision of a simple and efiective device by means of which air is forced directly through the body or mass of powder, and caused to throw the same in the form of sprayed dust or powder through the nozzle of the gun.

As heretofore constructed, guns for scattering powder have been formed with hollow bulbs placed at the end of long tubes away from the body or barrel of the gun. Our invention provides for placing the bulb or blowerimmediately at the end of said barrel, so that the whole device shall occupy but small space, and to guard against the easy escape or loss of the bulb the bottom of the convex plug or end is thick, and a tube or stem extends to the interior of the barrel through this thick end, so as to be held securely thereby and keep the bulb in place.

The accompanying drawingsillustrate what we consider the best means for carrying the invent-ion into practice.

Figure 1 is a side elevation of the device complete, showing the form in which the nozzle is removable, and the rear plug integral with the cylinder. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a central longitudinal section of the form in which the rear plug is removable, and the nozzle fixed or integral with cylinder or barrel.

Similar letters of reference indicate corresponding parts in all the figures where they occur.

A is the cylinder or barrel, formed of wood or other suitable material.

B is the nozzle or stopper, which is removable from the barrel or cylinder in the form shown in Figs. 1 and 2, or integral therewith, as shown in Fig. 3. In either case it has the conical or cup -shaped cavity B, and the opening or aperture 1), extending from the apex of the cavity to the top of the nozzle, and the sieve orstrainer O, placed over the entrance to the cavity B.

In the form shown in Figs. 1 and 2 a rim or flange, B of a slightly-tapering form, is secured to the lower end of the nozzle and enters the head of the barrel, its tapering form rendering it tight and secure. Ihe opposite or lower end of the barrel is closed by a plug or head, D, which may be integral with the barrel, as shown in Figs. 1 and 2, or separate and removable therefrom, as shown in Fig. 3. It has in either form a cup-shaped or con cave exterior, D, into which fits the air bulb or forcer E, which has an open stopper, 6, with an enlarged head, (2, for holding it securely in the bulb, said stopper or neck 6 passing through an opening in the plug or head D. WVhen the bulb is compressed, the air will be forced through the neck 6 and through the powder in the cylinder or barrel, throwing said powder out through the nozzle in sprayed or scattered particles.

In the form of plug or head shown in Fig.

3, as already stated, the head is removable and the powder is poured or introduced into the barrel through it, while in the form shown in 85 Figs. 1 and 2, where the nozzle is removable, the powder is introduced through that end of the barrel. In the removable form of plug or head a packing may be provided around it to insure a close tight fit, as shown at D 0 in Rig. 3. A second sieve or strainer, C, placed directly over the mouth of the stop per 6, as shown in Fig. 2, or at a little distance from it, as shown in Fig. 3, is employed to prevent the powder from falling into the 5 bulb.

\Vhat we desire to claim and secure by Letters Patent is In an insect-powder gun, the combination, with the barrel A and nozzle B b, of the con- 10o cave end plug or head having the thick bottom described, with a central opening therein, and the hollow bulb E, having the tube or neck 0, for insertion through the hole in 5 the thick bottom, and the flange or securing-ring e, for holding the neck in the bulb, as set forth.

In testimony whereof we aflix our signatures in presence of two witnesses.
