Application led January 29, 1927. Serial No. 164,5142.A
y This invention relates to a rota-ry rod weeder and pertains particularly to an improved .type of `such structure.
' The .primary object of this invention is vto provide, in a `manner as hereinafter .set
forth, a wee-der employing a `rotating rod of polygonal erom 4sectional contour ldesigned toroperate beneath .the surface of the ground andan improved means for imparting Yrotary .motion to such .a crod. y
Another object of the invention vis to provide, in a .manner :as hereinafter set forth, an improved -ftypeof power furnishing mechanism for `the operation of ,a weeder ofthe eharacterabove described, and an vimproved .methodof mount-ing said mechanism upon an vadjacent supporting structure.
A lstill further objectof the invention isto Provide, isn a manneras ,hereinafter set forth', an improved .means for mounting a rotary Weederrod. Y
vNumerous other objects and advantages of the invention ,will become apparentasfthe Ydescription of the same proceeds and ,the in:-v
vention will be best understood from a consideration of the'followingdetailed descripi tion taken in connection rwith .the accompanying .drawings forming a part of 'this Vspecilieation, with the .understanding however, that the invention Lis not confined to any strict Conformity with ,the ehowingof the ,drawings .but may be changed or modified so vlong as such changes or modifications mark no. mate- ,rial departure from the .salient features of the invention as expressed in the .appended claims.
In the drawings: v K Figure v1 is a `to Aplain view of one side of the structure em odying this invention,
Figure 2 vis a `rear .elevationof one vside of .the structure. l v
Figure Bis asideelevation ofthe machine, Figure 4 isa transverse section taken up on the line 4-14 ofjFi re 1, I Y
Figure 5 is a details side elevational view of one ofthe .supporting members for the rotaryban n Y Figure 6 ,is a vertical section the line 6 6 .of Figure 5, and Y Figure 7 isy a section taken upon'the line 7 7 of v'Figure 5.` f
` Referring now to the drawings detail wherein like numerals of reference indicate corresponding parts throughout thezseveral views, the weeder machine comprisesytwo elongated `spaced parallel 'beams land 2 taken upon Vvformed upon theouter face tions 6 of. two of the members 4, it being preacrosswhich beams there extends a vpair of .f
forwardly projecting shafts 3, which shafts are arranged in spacedrelation oneitherfside of the vtransverse center of thebeams- Lying beneath. the `beams 1 and 2 is a plurality of substantiallyfJ-shaped members, Y
.each indicated generally .by the numerals 4. The shank portion 5 of each ofthese members extends across the under faces ofV the .beams and is secured thereto and .these members are arran ed in spaced relation longitudinally `of V`the eam, :with their Shanks in parallel relation. The curved .or .hooked portion `6 of each of the members 17 extends vdownwardly beneath the machine and terminates ad- Vjacent the ground `.over vwhich thevehicle travels with the point directed towardthe front of the vehicle. r
The free end portion of eaeh member 17 is extended into and secured .to `the ground engaging body 7 which; has Yits forum-dpor-V tion formed to set up'the earth netrating ypoint 8 while formed transverse y .through :the body 1s an opening 9 Awhich is of width atithe forward ,portion than atthe .rear
and, inthe wall .of the forward-portion of this opening-a recess rl() is formed.
Extending longitudinally of .the vehicle,
rearwardly of the-beam 2 is an axle shaftl 11,
which extends through bearing ,bodies 1:2 `of .the hook por ferred that .this axleshaft 11 be mounted'upon the secondjand fourthonesof these-mem bers when five of the SameY are e layed.
The bearings 12 are so located that t e axle y shaft 11 is located substantially 'malignment with the beams l and 2, and .each md of vthe axle lshaft 11 is'bent downwardly, .as indi cated at 13 and terminates inthe outwardl directed stub sha-ft 14' which is parallel wi themain axle shaft 11as shown. Upon each of the stub shafts 14, a small traction wheel 15 is mounted,.which Wheels support'the device. I
Fixed to lthe axle shaft 11 intermediate .the ends thereof, is al collar 1 6 carrying the forwardly directed arm 17 and mounted upon the adjacent shaft 3 is a toothed se t 18. Pivotally mounted at the radial center of :the segment- 18 is a lever 19 carrying the usual dog 2O for engagement betweenV the .teeth of the segment, and the lever has a downwardly and rearwardly extending arm 21,-whieh Vis pivotally vconnected to the arm-17 by the link 22. :From the foregoing desriptiomit will be readily seen that upon oscillating the leverr19, the arm 17 will be swung causing the oscillation of the axle sliaft'll and in consequence, raising or lowering of the entire Vstructure upon the traction wheels 15.
Attached to the forward beam 1 is a pair of rearwardly extendingsprings 23, each of which has its other end connectedV to a downturned portion 13 of the axle shaft 11.. The tendency of these springs is to cause easier oscillation of the shaft 11 when the lever 19 is swung to raise the machine.
Extending longitudinally of the vehicle beneath the beam 2, is a rod or yshaft 24, of polygonal Cross sectional contour, the rod here shown being square. This rod extends p, throughthe aperture of each of the ground ,j whereupon therod and collars are moved towardthe pointed end of the member 7 to cause the collars to move into the recess in the constricted portion of the opening in which it is positioned.
Y A suitableretaining and bearing body 26 is then inserted into the enlarged portion of each` opening' behind the collar 25 located therein, after which Va cover plate 27 is se cured toeaeh side vof each body 7 to overlie the opening formed therethrough, each plate being provided with a suitable opening 28j for the extension therethrough ofthe rod 24.
' At one outerend of the beam 2 there is located an open frame structure indicated generally by the numeral 29' which frame structure is'of triangular configuration, in side elevation and isl made up of a pair of complementary members suitably joined in spaced parallel relation as is clearly shown in Fig- .'ure .1'. This frame is so mounted that the longv side @extends parallel tothe adjacent end of the beam 2 with the base portion 31 extending Vdownwardly and arranged a subA stantial distance beyond thcfouter end of the adjacent beam, the portionY 32 of the frame which forms'the hypothenuse extending upwardly and inwardly to meet the inner end of the side 30; vThe beam 2 extends between the ,inner ends of the long sides 30 of the -frame and is pivotally secured thereto by the `throughpin 33.
.Formed between the complementary sections of the frame adjacent the point at which Athe hypothenuse meets the base side, a pair of bearingsr'34 and 35 is formed, these bearings beinBg arranged in vspaced relation as shown in igure 2'and extending through and mounted therein is a hollow shaft 36 upon I cla-im is:
which is mounted between the bearings a beveled ear 37. The shaft 36' extends through t ie bearing 35, a substantial distance inwardly and beneath the frame 28, and as is shown, the relation of these bearings 3l and 35 is such as to direct the shaft downwardly toward the adjacent 'end ofthe rod 24. The shaft has a hollow bore therein of polygonal cross sectional design, to receive a similarly shaped stub shaft 38which is slidably extended thereinto. f'
A universal Connection39 joins the outer end of the stub shaft 38 with the adjacent end Y of the weeder rod 24. Means is provided for the support, by the frame 29, of a shaft 40 adapted to extend outwardly from the base of the frame and y'upon the outer end ofthe shaft a ground engaging wheel 41 is mounted while upon the inner portion of the, shaft a beveled drive gear 42 is secured Vwhich is designed to mesh with'the gear 37. As the machine passes over the ground the wheel 41 engaging therewith is caused to revolve,
turning ' thefgears 42 and 37 and thus imparting rotary motion to the shafts 36 and 38 and to the weeder rod 24. The frame 29Y being pivotally mountedfat'33 is adapted to move Vup and down in accordance with the surface of the groundi'andthe telescopingaction between the shafts 86 and 38 permits uninterrupted rotation of the weeder rod.`
Having thus described my invention, what l. In a rotary rod weeder, a ground penetrating shoe having an opening formed there- 100 through,` said opening being of gradually decreasing width' from one end to therother,
a circular bearingbody having a centralpassage therethrough designed Vto Vbe inserted in said opening andmoved to the end of smallest width, and means forffmaintaining said body in the openinggvsaid bearingbody being designed to receive in the passage formed therethrough, a weeder rod. i
2. In a rotary rod weeder, a ground penetrating shoe havingonel end tapered to a point,"and further having aV transverse opening formed therethrough and of gradually decreasing width toward the pointed end thereof, the central portion of thewall of said Vopening being provided. with a recess to makethe central portion ofv the opening of substantially constant width throughout,` a centrally apertured circular bearing `body de- Y signed to be inserted in the opening at the larger end thereof and moved forwardly Vinto said'recess, a retaining block positioned within'the opening to maintain said body'in posi: tion in the'recess, and means for retaining V said-blockin position, saidcircular bearing bodyI ,beingl designed to receivethro'ugh the passage formed therethrough,'a weeder rod.
3. InaV rotary rod weeder, a ground penetrating shoe having one end tapered toa 1 the central portion ofthe opening of substantially constant Width throughout, a centrally apertured circular bearing body designed to be inserted in the opening at the larger end thereof and moved forwardly into said recess, a retaining block positioned with- 10 in the opening to maintain said bodyin position in the recess, and plate members arranged one upon each side face of the shoe and overlying said block and secured to the shoe to maintain the block in position.
Inv testimony whereof I affix my signature.-
JOHN A. LINDQUIST.
