CULTIVATOR.
Specification of Letters Patent.
Patented Aug. 5, 1919.
Application filed January 26, 1918. Serial No. 213,994.
To all whom it may concern: Be it known that I, OT'ro Munmnn, a c1t1- .1 zen of the United States. residing at Elkton,
in the countyof St. Johns and State of Florida, have invented new and useful Improvements in Cultivators of which the following is a specification.
This invention relates to cultivators and it consists in the novel features hereinafter described and claimed;
An object of the invention is to provide a cultivator of simple and durable structure having its parts so arranged that they may be easily and quickly adjusted to meet the various conditions to which the cultivator is subjected.
With this object in View the cultivator comprises a beam having angle members pivotally connected therewith. Blades are carried at the outer sides of the said angle members and the lower forward portion of.
the said blades are outwardly curved and the upper rear portion of the said blades are outwardly curved. Standards are mounted upon the rear part of the said angle members and handles are adjustably connected with the said standards and are connected at their forward ends with the forward portions ofthe angle members. Suitable soil cultivating devices may be carried at the rear portions of the angle members. The lower part of the said beam is adapted to serve as a keel for moving at the center line of a furrow and the blades may operate along the sides of the furrow. The said beam is provided at its rear end with an upwardly disposed arcuate portion and a guide member is mounted for movement along the said arcuate portion. A spring is connected with the beam and is operatively connected with the said guide member by means of a chain. The said spring is under tension with a tendency to normally hold the said guide member in an elevated position. The rear parts of the angle members are adjustably connected with the end portions of the guide member.
In the accompanying drawings Figure 1 is a top plan view ofthe cultivator.
Fig. 2 is a side elevation of the same. Fig. 3 is an end view of the cultivator. Fig. 4 is a vertical central section of the samei. 11.;
.. Fig. 5 is a sectional detail showing the guide member.
Fig. 6 is a view in elevation of the beam.
The other figures are detailed views of the features of the invention.
The cultivator comprises a beam 1 the lower portion of which is in the form of a keel 2. The said keel 2 is adapted to travel along the center line of a furrow when the cultivator is'in use. A draft appliance (not shown) may be attached with the forward end of the beam in a usual manner. The beam 1 is provided at its rear end with an upwardly disposed arcuate portion 3. Angle members 4 are pivotally connected at the forward portion of the keel part 2 of the beam and blades 5 are attached to the outer surfaces of the forward parts of the angle members 4. The blades 5 are provided at their forward ends and at their lower edges with outwardly curved portions 6 and at their upper rear edges with outwardly curved portions 7. These curved portions terminate at their inner ends approximately at points midway between the ends of the blades and they are designed to encounter the soil at the sides of the furrow and turn or twist the same as the soil is being cast by the flat portions of the blades and thus the soil is turned slightly as it is being cultivated. Standards 8 are mounted at the rear portions of the angle members 4: and handles 9 are adjustably connected with the said standards 8. The forward portions of the handles 9 are pivotally connected with the forward portions of the angle members 4. A guide member 10 is slidably mounted upon the arcu'ate portion 3 provided at its ends with. flanges 11 which receive between them the inner portions of the angle members 4. The said portions of the angle members are secured to the end portions of the 'guide member 10 by means of bolts 12. The
guide member 10 is provided at its intermediate portion with flanges 13 which lie at the opposite sides of the arcuate portion 3. A spring 14 is mounted upon the beam 1 and is connected with the guide member 10 by means of a chain 15. Soil engaging members 16 may be carried by the rear portions of the angle members 4.
The spring is under tension with a tendency to normally hold the guide member 10 in an elevated position upon the arcuate portion 3 of the beam. Consequentlvan operator may exert downward pressure on the rear portions of the handle 9 whereby the blades may be caused to operate at desired depths below the surface of the soil. By providing the guide member 10 which is slidably mounted upon the arouate portions the end parts of the angle members 41 may be connected with the said guide member independently of each other and the end portions of the said angle members do not overlap each other and consequently the adjustment of one does not effect the adjustment of the other and therefore the forward portions of the said members may be disposed at different angles with relation to the longitudinal dimension of the beam and keel.
From the foregoing description taken in conjunction with the accompanying drawing it will be seen that a cultivator of simple and durable structure is provided and that the parts may be easily and quickly adjusted to meet the conditions existing in the locality at which the cultivation is taking place.
Having described the invention what is claimed is A cultivator comprising a keel having an upwardly disposed arcuate portion, angle members pivoted to the keel, blades carried by the angle members, a guide having flanges to slidably embrace said arcuate portion, and having end portions projecting laterally from said arcuate portion and formed with upper and lower flanges, the rear portions of the angle members being adjustably secured against such end portions and between the flanges, and resilient means for supporting the guide and blades. 44
In testimony whereof. I afliX my signature.
