JOHN H. KNAPP, OF DECATUR, ASSIGNOR TO JOHN ALEXANDER SUFFERN,
' OF PIERSON, ILLINOIS.
JoINT FO CULTIVATORS.
SPECIFICATION forming part of Letters Patent No. 531,592, dated December 25, 1894. Application filed September 22, 1 894. Serial No. 523,736- (No model.)
To all whom it may concern.-
Be it known that I, JOHN H. KNAPP, of Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Joints for Cultivators, of which the following is a specification.
This invention relates to the joints between the shanks of cultivators and the cultivating blades thereof. It is exemplified in the structure hereinafter described, and it is defined in the appended claim.
In the drawings forming part of this specification Figure 1 is a side elevation of a structure embodying my invention. Fig. 2 is a central vertical section from front to back through the joint. Fig. 3 is a plan of the device Fig. 4 is a horizontal section through certain parts, as indicated by line a; in Fig. 2.
The lower end of a cultivator shank is shown at 1. At 2 is shown'a shoe secured to the shank. 3 is a block adjustable in the shoe, and 4 is the bracket-shank which carries the cultivating blade.
The shoe is adapted to fit either a wooden or metal shank. It is concaved and corrugated in the concavity, as seen at 11; and it has a hole for the insertion of securing bolt 5. The block 3 has a convex surface adapted to conform to the concavity of the shoe. Such surface has teeth, or ribs, as 1 2, which engage corrugations of the shoe. The block is slotted to admit the bolt 5, and it has corrugated concavities 13. Shown only in Fig. 4. The bracket-shank 4 is rounded to conform ,to the concavities of the block, it has ribs 10 to engage the corrugations of the concavities, it is provided with ledges 8 and 9 respectively below and above the block and it carries the bracket 7 to which the cultivating blade 6 is secured. The bolt 5 has an eye which encircles the bracket shank. It extends through the slot of the block, the hole of the shoe and through the shank. It is secured in place by a nut which bears against a washer that rests against the shank, and it secures all the parts in any desired relation of adjustment and in connection with the shank.
The shoe is concaved with relation to a vertical line, and it permits the blade to be pitched with either end elevated, when it, the blade, is held oblique'with relation to the direction of motion, and the horizontal concavities of the block permit the degree of obliquity of the blade to be regulated. The function of the adjustment of the bracket shank in the block is to enable the soil to be carried more or less in either direction from the shank of the cultivator, and the adjustment of the block in the shoe permits the end of the blade next the rowto be elevated to avoid cutting roots. The bracket-shank is preferably recessed annularly to receive the eye of the bolt, in order that the surface may be smoother and the connection between the bolt and the bracketshank be more secure.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The joint for cultivators, comprising the shoe 2 having the vertical corrugated concavity 11, the block 3 adapted to the concavity of the shoe and having ribs as 12, the bracketshank 4 having rounded and ribbed surfaces adapted to corrugated concavities of the block, and the eye bolt 5 adapted to bind the parts together and to the shank of the cultivator, substantially as set forth.
In testimony whereof I sign my name in the presence of two subscribing witnesses.
JOHN H. KNAIP.
