POISON-DISTRIBUTER.

SPECIFICATION forming part of `Letters Patent No. 628,920, dated JulyV 18, 1899.

' Application lerl April 5, 1899.` Serial No. 711,866. (No model.)

T @ZZ whom it may concern:

Be it known that I, EML BRAUN, a citizen of the United States, residing at Moulton, in'

the "countyof Lavaca and State of Texas, have invented a certain new anfduseful Poison: Distributer, of whichthe follow-ing is a speci ication.

My invention relates to that class of machines used for distributing poisons in the form of a powder upon plants for the purpose of killing insects which infest the plants, the object of the invention being to generally improve the construction and operation of that class of machines.

l/Vith this object in View my invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward specifically pointed out in the appended claims.

In order to enable others skilled in the art to make and use myinventiomlwill now proceed to describe its construction and operation,reference being had to the accompanying drawings, forming part hereof, in whieh- Figure 1 is a plan view of a machine constructed in accordance with my invention the tongue or pole being broken away to shorten. the iigure. Fig. 2 is a view in elevation of the right-hand side of the machine. Fig. 3 is a transverse vertical sectional view taken on the plane indicated by the dotted line 3 3 of Fig. 2 looking in the direction of the arrows. Fig. 4 is a detail sectional view taken on the plane indicated by the dotted line 4 4 of Fig. 2 looking downward, as indicated by the ar-` rows. Fig. 5 is a transverse vertical view of the powder-hopper and blower-pipe. Fig. 6 is a detail perspective `view of the stirring mechanism removed from the hopper. Fig. 7 is a detail perspective view of the upper part of the powder-hopper and its hinged hood. Fig. 8 is a detail vertical sectional view on the plane indicated by the dotted line S Sof Fig. l. Fig. 9 is a detail vertical sectional view on the plane indicated by the dotted line 9 9 of Fig. 1. Fig. 10 is a detail vertical sectional view on the plane indicated by the dott-ed line 10 10 of Fig. 1. Fig. 1l is a detail vertical sectional view on the plane indicated by the dotted line 11 11 of Fig. 5.

Like numerals of referencemark the same parts wherever they occur in the various tigures of the drawings.

` Referring to the drawings by numerals, 12

indicates an ordinary cart frame or body mounted on wheels 13 and 14, the former being an ordinary wheel and serving only as a support for the body and the latter the driving-wheel of the distributing mechanism. The traction-wheel 14 is provided with a large gear-wheel 15, formed with a lateral or circular angular iron iiange 16, the gear-wheel being secured to the traction-wheel bymeans of clamp-bars 17 outside the wheel and bolts 18 securing them to the circular iiange. The gear-wheel meshes with a pinion 19, mounted loosely on the main driving-shaft 20, journaled in pillow- blocks 21 and 22, mounted on the cart-body. The gear-wheel 15 and pinion 19 are protected by a sheet-metal guard 23, secured to the frame of the body. The hub of the pinion 19 is extended at 24 to form one member of a ratchet-clutch, the other mem- V ward the shaft 2O is rotated; butwhen the cart is backed the teeth of the clutch members slip over each other and the shaft remains still. A shifting-lever 27, pivoted to an extension of the pillow-block 21, serves to withdraw the clutch-sleeve 25 and throw the distributing mechanism out of gear whenever desired during the forward movement of the cart.

, A gear-wheel 28 on the shaft 2O meshes with a pinion 29 on a shaft 30, journaled in pillowblocks 31 and 32, mounted on the cart-body, which shaft 30 carries a beltpulley L33, connected by a belt 34 with a small pulley 35 on the shaft 3G of a fan or blower 37, the blast from which is discharged through a pipe 3S, passing under. a hopper 39 and provided be yond the hopper with two elbows 40 and 41,` the latter pivotally mounted on its transverse axis and carrying at the extremity of its lon Zles are cut olf at their outer ends at an in- IOO Ixo

- l^and 52, journaled in standards 53, mounted on the cart-body, passing between said standard and guided thereby.

The hopper is provided with a hood 54,-

hinged at one side to an arm 54, projecting above the hopper, and provided at its opposite side with a spring-latch 55 to engage a keeper 56, secured to the side of the hopper to hold it down when the distributer is in operation.

y its lower end in a fitting consisting of a nipple 6l on a plate 62. A similar but reverse fitting, consisting of a plate 63 and nipple 64, is secured below the fitting iirst named by bolts 65, carrying separators 66, leaving a` space between the plates 62 and 63, in which is pivotally mounted on a bolt 67a cut-off or trap-door 68, connected at its outer end with a rod 69, extending to and connected with a hand-lever 70, pivoted to the cart-body and provided with a spring-pawl 71, engaging a curved rack 72, secured to the body. A short nozzle 73 depends from the nipple 64 into the blower-pipe 38, vsaid nozzle being out offat its lower end at an inclination, as at 74, and arranged with its longest size toward the blower.

Upon the Y-fitting 42 is a ring 75, from which projects upward an arm 76, pivotally connected at its outer end with the rear end of aA rod 77, which is pivotally connected at its front end with a hand-lever 78, pivotally mounted on the cart-body and provided with a spring-pawl 79, engaging a curved rack 80, secured to the body.

The hopper 39 is supported by u prights on each side, each set consisting of a forward but rearwardly-inclined bar 8l and a rear forwardly-inclined bar 82, a bolt 83 passing through the upper ends of the bars of each pair into the hopper. The bars 8l and 82 of each set are further secured together and to the hopper by a bolt 84, which passes through a clamp-bar 85 on each side and into the hopper.

The cart is provided with asuitable springsupported seat 86, positioned within easy reach of the hand-levers, and with ordinary `.upon two adjacent rows of plants.

tongue or pole 87, doubletree 88, and singletrees 89;

The construction of my improved machine will be readily understood from the foregoing description, and in operation the poison in form of powder will pass down out of the hopper 39 into the blower-pipe 38 and through this pipe and the nozzle 43 will be sprayed The nozzle 73 prevents the powder from being blown back into the hopper, and the elevation at which the powder is delivered may be regulated by raising or lowering the nozzle 43 by means of hand-lever .78 through the medium of the rod 17 and arm 76. The amount of powder delivered is governed by the cutoff or trap-door 68, operated by hand-'lever 70 through the medium of rod 69.

The distributing mechanism is only operated when the cart moves forward and can be thrown out of gear at any time by the clutchshfting lever, as before described.

All the parts of the machine are simple in construction, their number is limited to the minimum-requisite for proper operation,their arrangement is simple, they are not liable to breakage or disarrangement from ordinarily careful use, and may be assembled or separated by ordinary unskilled labor with a wrench and screw-driver.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a machine for distributing pulverized poison, the vcombination with a blower and a hopper, of a pipe leading from the blower, a pipe leading fromv the hopper to the blowerpipe, two elbows in the blower-pipe forming a reverse bend, the last elbow having one of its arms transversely placed and pivoted in the first elbow, nozzles extending from its final longitudinal arm, and an arm, rod,handlever, and curved rack for adjusting the elevation of the nozzles, substantially as described.

2. In a machine fondistributing pulverized poison, lthe combination with the blower and delivery pipe of an elbow therein pivoted on the transverse axis of its inner arm, a pipe leading rearwardly from its final longitudinal arm, a Y-fitting in said pipe, branch pipes in the diverging arms of said fitting, sprayingnozzles at the extremities thereof, and means for adjusting the inclination and elevation of the -flrst named pipe, substantially as described.

3. In a machine for distributing pulverized poison, a hopper terminating at its lower end in a funnel, a casting consisting of a flat plate and an upwardly-projecting nipple connecting with the funnel, a like casting consisting of a plate below the former plate and a nipple leading toward the blowerpipe, separators between the plates, a cut-off door pivoted in the space thus formed, and a rod, hand-lever and curved rack for operating the cut-olf,

substantially as described.
