CLINTON H. LEGGETT, OF NEW YORK, Y.

INSECTICIDE-DISTRIBUTER.

Specification of Letters Patent.

Patented March 30, 1909.

Application filed July 22, 1907. Serial No. 385,079

To allwhom 'it may concern.' l

Be it known that I, CLINTON l-l. LEGGETT,

Va citizen .of the United States, residing in the borough of Manhattan, city, county,l and.

State of New York, have invented certain new and useful Improvements in Insecticideg Distributers, 'of which the following is a specification.

This invention relates to insecticide distributers and is particularly directed to port.- abledistributers adapted to be carriedby l the operator.

The object of the present invention is to rovide a cheap and simple distributer whichv is adapted to distribute the insecticide in powdered form over several rows of plants;

which is adjustable to alter the distance hetween the distributing nozzles so that rows of .different distances apart may be dusted and which is provided with a means wherebv it may be easily carried, so as to render it particularly adapted for manual use.

:Inthe drawings, wherein l have showna form of my invention, Figure 1 is a erspec.

tive view of the machine showing t e maiiner in which it is carried by the operator.

Fig. is anenlarged side elevation with the distributing nozzles removed. Fig. 3 is a horizontal section taken approximately on the line 3-3 in Fig. 2. Fig. 4 is a section of one-of the pipe connections in one position. Fig. 5 is a similar section in another position.

Fig. 6 is a detail of the connection between the pinion and its sli-aft.

Referring to the drawings the distributor A com )rises a reservoir B for the powder,

and a an C rotating in a casing l) which is connected with the air passage E passingiV beneath the reservoir B and terminating in the nozzle F. rlhcsc parts are in general ol the usual construction.

lIn the reservoir B is mounted an agitator having arms c c carrying blades l) b,f

which are adapted to brush the powder across suitable apertures in the bottom of the reservoir in the well-known manner. The operating handle Gis mounted upon a gear lc fixed directly to the shalt d of the agil The power is SI transmitted to the lfan vshaft c by gears f, g,

tutor as best seen in Fig. 3.

bandi..

lt 'is an advantiige to avoid tht` use of t iisl kind, and this is accomplished in the present construction without undue friction sprocket chains or belts in distributei's of g l merely to transmit power from the gear g to l the gear z'.

ln order to avoid unnecessary friction and weight it is desirable that the distance .between t-lie fan and the reservoir be shortened as much as possible. In the construction shown this is done with the eliect that onlg a single transmission gear h is required. preferably provide a single plate j to form a bearing or support for all of the shafts used on the device; such plate extending from the tan casing to the reservoir, as shown in Fig. 3. This plate forms a bearing for the fan shaft and agitator shaft and a support'for screwi threadedstuds 7c and l for the-gearsf, g and h. The gear i is preferably provided with a notched extension m which is designed to rei ceive a cotter pin n which passes through a i hole in the shaft@ (see Fig. 6). This construction avoids'tlie necessity of squaring or feathering the shaft and gear and at the same time provides a'seeure nonrotative connection which is capable of being disengaged wit-hout dilliculty.

In devices of this kind considerable ti'ouble is sometimes found in keeping the bearings of the agitator and fan shafts lubricated. The cheapness of construction of the device prohibits the use of means which may be effectively employed in other connections. I i have found that if a small piece of leather such as o he held in place around the ends of the shafts and occasionally well supplied with oil, a continuous and proper lubrication of the shafts can be obtained. Iprcferablyprovide a strap ol' metal p to hold the latter in place.

My invention includes a very means for supporting the distributer upon the person of. the operator. `his means, as

l indicated in Fig` 1, con'iprises a lexible inem-l i her such as thc rope ll which is provided with an eye at one end adapted to engage a g hook q fastened to they discharge nozzle F of the distributer. The rope H is then led through an eye r on the top of the reservoir f and passed over the left shoulder of the 0perator, and thence downwardly lunder his right arm and is there fastened to a cleat or other similar device sfixed to the fan casing` By this means the distributer is held very firmly iii its proper position with its fan casingr resting-against theiront of the operator. l 'lhe connection o`f the rope H with the reservoir by means of the-eye lr prevents any lat- Other similar xeral swaying of the device.

y means for su porting the distributer can bel employed Wit out departing from theinvention. I prefer, however, the construction just described, since it is easily adjustable to` alter the position of the machine by means of the cleat s. It is also very desirable since it permits the device to be erators of diiierent heights.

The hook ginay. be aiiixed to the discharge nozzle F in any tofform -it vwith a ring sha ed shank, as best seen in Figs. 2 and 3, an to-solder it to the nozzle.

' vnozzles so that two rows of 'i shown a pipe connection t having branchesv .Y pipe u by means of a length -of rubber hose vor other flexible material v.

In Fig. 1 I have illustrated my invention as adapted ,for use with two distributing lants may be simultaneously dusted. In t iis figure' I have t and t2, such connection being adapted'to t over or `in the nozzle To each of the branches t and t2 is connected a distributing The connections eare sufiiciently stiH to support the .distributing pipes. f It is frequently desirable to adjust the distance between the distributing nozzles w w `to suit rows 'whichvare diiierently spaced apart. According to the present invention.

I provide a very simple and eilicient means for a'ceomp'lishing ,this result. In the construction shown such means comprises the brace having its ends somewhat loosely stra ped tothe pipes 'u in such mannerthat the race can be adjusted lengthwise of the latter. It will be observed that when the brace is'moved, rearwardly the outer ends of the lpipes are caused to diverge and that when the braceis moved forwardly the opposite effect is obtained. By merely adjusting the brace therefor the pro ,er distance between'the.nozzlcs'can be o tained, the

brace remaining in its adjusted position by friction. The connections v are suilicicntly vflexible to permit the necessary movement vof the pipes. As will be seen from Fig. 4 it is desirable to provide the pipes 'It with a s houlder such as y to prevent the pipes from being pushed too far into the iiexible tubes/v.

The dcviceprovided by my invention is, of course, susceptible of being used with more than two nozzles, Vor with a single nozzle. In 'a great majority of cases, however, two nozzles will be sufficient. I .may provide in connection with the machine a pipe having a single nozzle which is adapted to iit over t e nozzle 11. I prefer7 however,

' to utilize one of the pipes u, andthus avoid the necessity of supplying aseparate pipe. To this end I so,- proportion the shoulder or ring y and theiijozzle F that the pipe u with Y its ring fits within the nozzle F, as shown in Fig.' 5. By this construction it is only necessary toremove voneof the pipes from its flexible connection'v and free it lfrom the suitable. manner, but I prefer brace z, whereupon `the pipe can be inserted inthe nozzle-,F and the duster thus adapted for single rows or the like.

a hook g which is similar to the hook g so that the ilexible member H. may be engaged at a point farther forward than the hook q. This provides a smewhat better support for.7 the device when the several nozzles are used.

It will be seen thatiby my invention Iiprovide an extremely cheap and simple distributer which is capableof being carried in the hand or supported u ,on the person and rows of plants simultaneously in an efficient manner. i.

What I claim is casing, a reservoir anda discharge nozzle in combination with a' liexible member fastened yto such discharge4 nozzle and havin a sliding connection "with the top of sai reservoir, and being adaptedto pass over the shoulder of the operator, and a cleat secured to said fan casin to which said flexible member is adapte to be fastened. 2.
