Abstract: Closely spaced cultivating tools are mounted along a tool bar and each tool may be locked in a raised position relative to the ground or may be lowered into floating engagement with the ground during use of the implement. A small tool bar is mounted parallel to a larger tool bar and the cultivating tools are slidably clamped on the small tool bar. Improved mounting structure allows each cultivating tool to be mounted on the small tool bar without having to slide each cultivating tool onto or off of the tool bar from the ends of the tool bar and without having to disassemble the mounting structure. The tool bar assembly includes row indicia for indicating where the tools are to be located along the tool bar and which tools should engage the ground and which tools should be raised away from the ground for various cultivating operations on row crops. A tool angling mechanism allows selective adjustment of the angle to the line of draft of each tool without the use of wrenches or other hand tools.

Abstract: A self-locking hinge for use as a pivotal connector between two pivoted members and adapted to lock the members in a fixed angular relation. The hinge comprises a pair of circular plates that are rigidly affixed to opposite faces of one member and rotatably connected to the other member. The circular plates are used to laterally support both of the members and to guide the other member as it is rotated from a folded position to a fully extended position. The hinge is locked in the fully extended position by means of a locking ring that is slidably engaged with the other member. When such other member is fully extended, the ring engages corresponding locking indentations at the periphery of the circular plates and thereby blocks the movement of the other member in one angular direction. The movement of the other member is blocked in the opposite angular direction due to the abutting of the hinge ends of the members.

Abstract: A self-locking hinge for interconnecting two structural elements such as sections of tent poles includes a pair of bifurcated lugs in opposed end-to-end relationship and a yoke extending between the arms of the lugs. A pin extends through the arms of each lug and a slot or slots in the yoke for pivotally connecting the lugs to the yoke. The pins are biased towards each other by a spring in the slot or by springs in the slots, so that projections on the arms of one lug are biased into grooves in the arms on the other lug to lock the hinge in an open position. In order to close the hinge, the lugs are pulled slightly apart against the action of the spring(s) to remove the projections from the grooves, permitting rotation of the lugs relative to the yoke and to each other.
