T 0 all whom it may concern:

Be it known that I, Josnrrr F. LnMoNs, a citizen of the United States, residing at Adams, in the county of Robertson and State of Tennessee, have invented certain new and useful Improvements in Dust Guns,of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in dust guns and has relation more particularly to a device of this general character especially designed and adapted for use in spraying foliage and the like with powder for protecting them from insects, and it is an object of the invention to provide a novel and improved device of this general character whereby the requisite draft or blast may be created by means of which the dust or powder may be distributed. t

It is also an object of the invention to pro vide a device of this general character with novel and improved means whereby the dust or powder within the containing hopper may be properly delivered or fed to a distributing tube to be acted upon by anair blast.

The invention consists in the details of construction and in the combination and arrangement of the several parts of'my improved dust gun whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view in side elevation of a dust gun constructed in accordance with an embodiment of my invention, the discharge end of the delivery conduit or pipe being broken away;

- Figure 2 isa view in top plan of the device as illustrated in Figure'l; 1

Figure 3 is a longitudinally vertical sectional view taken through the device as here- 7 in embodied;

Figure 4 is a horizontal sectional view taken longitudinally through the hopper and casing, certain of the parts being in top plan; and

Figure 5 is a fragmentary transverse sectional view taken through the wall of the hopper and the bearing carried thereby.

---As disclosed in the accompanying drawings, H denotes a hopper of predetermined capacity and which has its upper end open and associated with said open end is a sliding closure member 1. Extending beneath the hopper H is an elongated delivery conduit or pipe 2, said conduit and hopper being in communication one with the other through an opening or port 3. v

The hopper H is positioned intermediate the ends of the conduit or tube 2 and disposed on one end portion of the conduit or tube 2 is a fan casing 4 having the outlet thereof in communication with the conduit or pipe 2; The casing 4 is spiraloid in side elevation and has disposed therein a fan 5 arranged at substantially the center'of the spiral whereby the casing forms about the fan a constantly increasing path toward the discharge thereof for the passage of the air. 1 The fan 5 is fixed to a shaft 6 and carried by said shaft 6 within the casing 4 is a beveled pinion 7. The fan casing4 and the hopper'H are connected by a bracing member 8 whereby additional rigidity is impart- I ed to the assembled device. The casing 4 adjacent the pinion 7 is provided with a removable side plate 9 herein disclosed as circular in form and the central portion of said plate 9 is provided with a slotor opening 10 through which extends a portion of a gear 11 meshing with the pinion 7 here-inbefore referred to. I

The portion of the gear 11 exteriorly of the casing 4 is contained within a housing or boxing 12 provided with a forwardly disposed extension 14 providing a bearing for the shaft 15. The. shaft 15 extends Within the housing or boxing 12 and the gear 11 is fixed thereto. The housing or boxing 12 is adapted to contain grease or other suitable lubricant and in order to apply such lubricant, the housing or boxing 12 is provided with a filling vent 16 normally closed by the plu 17 or the like.

C onnecting similar side faces of the housing H and the casing 4 is a sleeve 18 through which the'shaft 15 is directed, the end portion of the shaft 15 remote from the boxing 12 being mounted in a bearing 19. The hear-- ing; 19 is carried by a plate 20 fixed to side wall of the hopper H. The bearing 19 provided with an oil opening 21 to facilitate the desired lubrication of the portion of the shaft 15 within the bearing 19.

The bearing 19 at its outer end is continued by a housing for a beveled pinion 23 fixed to the adjacent end of the shaft 15 and said housing is also provided with an oil opening The pinion 2; meshes with a gear 25 fixed to one end portion of a sea 26 rotatably supported by the hopper c7-1tcriorly thereof and extending transversely of the hopper. The end portion of the hopper remote from the gear 25 is provided w'th an operating member 2? herein disclosed as a crank.

Rotatably mounted within the hopper H approxin'iately vertically above the openin 3 is a shaft 27, said shaft extending exteriorly of the hopper H through the plate 20. The shaft 27 has secured thereto interiorly of the hopper ii an agitating: element. 28 herein shown as a brush.

Secured to the exterior or extended portion of the shaft 27 is a member or hub 29 provided at substantially diametrically opposed points with the outstanding and radially disposed members 30 and 31. The member 30 extends in a direction away from the gear 25 and has secured thereto an end portion of a retractile member 32', the opposite end portion of the member 32 being anchored, as at 38, to the adjacent side wall of the hopper H at a point in close proximity to its open or upper face. The retractilcmember 32 is herein disclosed as a coiled spring and serves to automatically impart rocking movement to the shaft 27 in one direction.

The second member 31 is of a length to terminate in close proximity to the periph cry of the gear The gear 25 has extending outwardly from its periphery a plurality of circumferentially and preferably equidistantly spaced teeth or lugs 34 whereby, upon rotation of the gear 25, the lugs or teeth 34 engage the member 31 and intermittently rock or oscillate the shaft 27 in one direction. The spring 32 under normal conditions, or before being expanded, operates to maintain the membe 31 in position for engagement with the lugs 34.

The forward or discharge end portion of the tube or conduit 2 may be provided with a suitable nozzle (not shown).

In practice, the assembled device is supported upon the body of a person or otherwise and the hopper H being first filled with a dust or powder destructive to insect life, the handle is utilized to rotate the gear 25 through the medium of the shaft 26.- The rotation of the shaft- 26 is transmitted through the gear 25 and the shaft 15 to the fan 5 with a much increased speed, thereby producing a blast or current of air through the tube or conduit- 2 to effectively discharge the dust or powder delivered within the tube or conduit 2 through the opening 8.

[is the gear rotates, the lugs or teeth 34, together with the retractile member or spring 32, effects an oscillation of the element or brush 29 and at each oscillation of said member or brush a certain amountof powder or dust within the hopper H is delivered within the tube or conduit 2 The side wall of the casing l remote from the plate provided with a suitable opening 35 to provide for the requisite ingress of air wi thin the casing: during the operation of the fan 5.

From the foregoing description it is thought to be obvious that a dust gun constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it maybe assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim: I
