Application filed July 2, 1918. Serial No. 777,083.
To aZZ whom it may concern: Be it known that I, JOHN S. DE Lone, a citizen of the 'United States, residing at Osborn, in the county of-Greene and State of Ohio, ful Improvements in Weedersand Soil-Pulverizers, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to new and useful improvements in weeders and more particularly to a combined weeder and soil pulverizer and the object of the invention is to provide a device of the above character which is especially adapted for use in pulverizing the soil and destroying small weeds between the rows and around the plants.
Another object of the invention is to provide a weeder of the above character which will possess advantages in points of eificiency and durability, is inexpensive to manufacture and, at the same time, is simple and etlicient in operation.
With the above and other objects in view, the invention consists in the novel features of construction, combination and arrange-' front elevation.
ment of parts as will be hereinafter referred to and more particularly pointed out in the.
specification and claims.
In the accompanying "drawings forming a part of this application, Figure 1 is a top lan view of a cultivator constructed in accordance' with my invention. Fig. 2 is a Fig. 3 is a longitudinal sectional view. Fig; 4 is a detail perspective view of one of the weeding knives. Fig. 5 is a longitudinal sectional view through one of the shafts. Fig. 6 is a detail perspective view of one of the spider-pronged wheels. Fig. 7 is a detail perspective view illustrating a modified form of spider disk detail perspective view illustratin another modified form of spider dis wheel. a
Referrin more particularly to the drawings, 1 in 'cates a handle member, to the outer end of which is s'ecured 'a transverse handle bar 2 and to the inner end thereof are secured the spaced arallel arms 3, the outer'ends ofwhich are ownwardly curved, as shown at 4.; Angular supporting brackets 5 are provided, the inner ends of which afe secured to the arms 3, adjacent the handle, by means of bolts 6, the outer ends ofsaid brackets being downwardly curved as shown have invented certain new and use,
at 7, to conform to the curvature of the outer ends of the arms 3.
A pair of longitudinal axles 8 are provided and arranged between the outer ends of the-brackets 5 and the arms 3, the ends of said axles being rotatably mountedwithin suitable bearings formed in the lower ends of the brackets 5 and the arms 3 and securely by means of the pins 9. Rotatably mounted upon the shafts and arranged between the outer ends of the brackets 5 and the arms 3, area plurality of disks 10, said disks being provided upon one side thereof with the radially arranged sockets 11 in which are mounted the inner ends of the radially projecting teeth 12, said teeth being securely retained within the sockets 11 by means of the set screws 13, any other well known form of fastening means being used, if desired. From this it will be seen that pressure exerted against the handle bar 2 will push the'frame of the weeder forwardly and rotate the disk 10, the teeth 12 engaging within the surface of the soil and as they move upwardly, the and any small wee s or undesirable plants will be readily removed from the soil to the top of the ground, where they will-pro: vide sufficient mulching. for the soil.
Removably clamped to the side portions of the brackets 5 and arranged at the rear of the disks 10 are the weeding knives 14,
the shank portions of said knives being securely held in position by means of the clamps 15 which are carried on the side porof the brackets 5 and in which the tions shank portionsof the knives are removably arranged. When the knives 14 are disposed in inoperative position, they are arranged above the frame and the lower ends thereof are disposed. upon a level with the shafts 8 and rotatably mounted within the lower ends of the shank portions of the knives 14, is a second shaft '16, which is arranged at the rear and in spaced relation to the shafts8 and' upon which are mounted the disks 17 The disks 17 are similar in construction to the disks 1O and-are provided ent that the disks 17 are preferably used in 1-10 will pry the soil loose held against longitudinal movement with a plurality of radially projecting teeth place ofthe knives 14, under certain conditions of the soil but, on the other hand, when it is'desired to use the weeding knives 14',
position at the rear. of the disks 10. The
two disks which are arranged adjacent the inner ends of the shaft 8, are provided upon their peripheries with the rims 18. Mounted upon the inner ends of the shafts 8 .and projccting at right angles thereto, are the arms 19, the inner-ends of which are bifurcated,
as shown at 20 to form'the spaced ears 21,
adapted to be arranged upon opposite sides of the lower ends of the arms 3 and mounted upon the shafts 8, the arms 19 being securely held in their operative positlon by means of the cotter the shafts. Mounted upon the outer ends of the arms for rotation, are the hubs 23 which are provided with a plurality of radially projecting teeth 2 adapted to engage the teeth 12 upon the two disks ,arranged at the inner ends of the shafts 8, so that upon the rotation of the disks 10, the hubs 23 will be rotated through'the engagement of the teeth, the teeth 24 loosening the soil within the rows and between the plants, while the teeth 12 upon the disks 10 will loosen and pulverize the soil upon opposite sides of the rows. The hubs 23 and the arms 19 may be :quickly and readily. removed from the inner endsof the shafts 8 and the spider-pronged wheels 25 may be mounted upon the inner ends of the shaft and used in place of the hubs 23 and the teeth 24. From the illustration shown in the accompanying drawings, it will be readily apparent that the outer ends of the teeth upon the wheels 25 are inwardly curved, as shown at 26, so that upon the rotation of the wheels, the soil around the plants may be readil loosened and by having the outer ends 0 the teeth inwardly curved, it will loosen the. soil more closely about the plants than it would doif the teeth were'straight.
- In Fig. 7, I have illustrated a slightly modified form of the s ider-pronged wheel in which the wheel consists of two clamping plates 27, the opposed faces of which are provided with suitablecurved grooves adapted to receive the intermediate portions of the teeth 28. The teeth 28 are formed in pairs and constructed of a single length of heavy wire or a rod, the intermediate portion of which is bent upon itself to form a curved portion, as shown at 29, which is adapted to be disposed within the grooves formed in the inner faces of the plates 27'. These plates 27 are securely clamped together by means of a bolt 30 and it will be understood that one or more of these bolts pins 22 arranged in the ends-of- .may be used and if desired, they may so arranged that thebolt will pass through the plates at a point inside of the curved portion 29, thus leaving a central opening in the 'readily mounted upon the axle or removed therefrom.
In Fig. 8, I have illustrated another modified form of the spider disk wheel which includes a hub member 31 having the radially projecting spokes 32 secured thereto, said spokes being securely retained in spaced relation at their outerends by means or the annular band 33. The band 33 is provided in its central portion with a plurality of circularly arranged openings 3 1 through which the spokes 32 are adapted to project. This band 33 is preferably arranged midway between the outer endsof the spokes and the hub 31. It will be apparent that the band 33 not only retains the spokes in their relative positions, but serves to strengthen the wheel as a whole.
From the above description taken in connection with the accompanying drawings, it will be readily apparent that I have provided a'simple anddurable Weeder and soil pulverizer wherein the soil between the rows and around the young plants may be quickly and readily pulverized and eliminated of weeds. It will also be apparent that should the disk 10 be arrangedu'pon the axles 8 at an angle with respect to the frame of the 'weeder, the teeth 12 will have a tendency to engage more deeply into the soil and stir the same more thoroughly and destroy even the larger weeds between the rows of the young plants. It will also be apparent that the spider-pronged wheels 25 may be quickly and readily substituted when desired for the hubs 23 and the teeth 24. My improved weeder, as above described and shown in the accompanying drawings, is extremely simple and durable in construction and can be man:
'ufacture d at a comparatively low cost.
\Vhile I have shown and. described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportion may be resorted to for successfully carrying my invention into practice vwithout sacrificing any of the novel features or, departing from the scope of the appended claims.
Having thus described this invention, what is claimed is 1; A weeder including a handle member,
spaced parallel arms secured thereto, angular supporting brackets secured to said arms,
the outer ends of said brackets and arms being downwardly. curved and arranged in longitudinal alinement,
mounted in the outer ends of the arms shafts rotatably and brackets and arranged upon'opposite sides of the center .of the handle, and cultivator disks mounted upon said shafts and adapted to rotate therewith.-
2. A weeder including 'a handle member, spaced parallel arms secured thereto, anguv lar supporting brackets secured to said arms,
cultivator disks rotatably mounted between the outer ends of the arms and brackets, a'
rotatable, shaft supported by said brackets and arranged at the rear of the cultivator curved and arranged in longitudinal alinedisks, and a second set of cultivator disks mounted upon said shaft and adapted for I rotation therewith.
3. A weeder including a handle member,. spaced parallel arms secured thereto, sup-- porting brackets secured to the arms, the outer ends of said arms and brackets being and adapted knives being adjustably mounted upon the side portions of the brackets, a shaftjournaled in the lower ends of said shank portions and arranged at the rear of the cultivator disks, and a second setof cultivator disks mounted upon said shaft and adapted for rotation therewith.
4. A weeder including a handle member, spaced parallel, arms secured, thereto, angular 'supportin brackets secured to said arms, shafts rotata ly endsof said arms and brackets, cultivator disks mounted upon said shafts and adapted for rotation'therewith, outwardly projecting; arms removably mounted upon I the inner mounted within the outer ends ofsaid shafts, hubs rotatably mounted upon the outer ends of said arms, and radially projecting teeth carriedby said'hubs cultivator disks to rotate the same.
In testimony whereof I hereunto aflix my' signature in the presence of two witnesses.
