Abstract: A foldable agricultural implement for use in a towed relationship with a tractor, wherein a pair of outboardly wheeled implement frames or wings carrying around working tools are rotatably and pivotally supported at their inboard ends by a wheeled rear carrier. The implement frames are connected to the rear carrier by ball-and-socket joint assemblies and are pivotally and rotatably connected to a towing means by a twin tongue assembly, adapted so that the work performing means are capable of maneuvering and closely following the contours of a field and folding forward and elevating to provide ground clearance for transport.

Abstract: An apparatus is disclosed to perform a method of tilling the soil on a crop field that: will hold rainwater where it falls, increase the percolation rate of this water into the soil, and provide storage room above and below ground level for this water. The tillage method depends on forming a series of small, flat topped terraces with interconnecting lateral dams. These small, flat topped terraces are sized, laterally spaced, and flat topped so that row crops can easily be planted on top of them. The small, flat topped terraces are generated during a deep soil tillage operation. An apparatus is provided to generate these uniformly spaced, flat topped terraces with lateral dams in a four-step process while traveling in either direction across a sloping crop field. Small supplemental tillage means may advantageously be provided for lateral dam generation under adverse soil conditions.

Abstract: The invention comprises an adjustable scraper device for scraping the disc blades of a grain drill. The device has a fixed mounting on the mounting for supporting the disc blades and a slidable mounting slidable along the fixed mounting to a selected adjusted position relative to the disc blade support mounting and the disc blades. Scrapers are mounted to the slidable mounting between the disc blades to be slid with the slidable mounting toward the center axis of the disc blades so that as the disc blade outer circumferential edge wears down, the scrapers, which act to scrape the disc blades, may be adjusted toward the center axis of the disc blades to keep the entire scraping portion of the scrapers within the confines of the outer circumferential edge of the disc blades, so that the scraping portion of the scraper will not wear on the outer edge of the disc blades and cause damage to the scraping portion of the scraper.

Abstract: An apparatus for mounting a dozer blade for vertical and angular movement relative to a frame of a wheeled implement. The mounting apparatus a mounting mechanism which allows the dozer blade to be mounted close to the wheels to either end of the implement and which permits angular movement of the blade about a generally vertical axis and vertical movement of the dozer blade about a generally horizontal axis. The mounting apparatus further includes a linearly distendable driver which extends laterally across the frame of the implement and a linkage mechanism which improves angling moments and maximizes the driving force imparted to the blade upon extension of the driver. The linearly distendable driver and linkage mechanism operate in combination and in a closely confined area adjacent to the implement frame for effecting extended angular movement of the dozer blade.

Abstract: Lift arms on a gang of implements support transport wheels which are movable from a raised field-working position to a lowered endwise towing position. Several of the wheels at the forward and aft ends of the towed gang of implements are fitted with castering pivots located adjacent the wheel hubs close to the wheel centerlines to lessen side loading and tire scuffing during turns. The castering wheels include a caster control assembly having at least four functions. First, a lock feature includes a spring-biased pin selectively engageable with the control assembly to secure the wheels in an in-line position to permit easy backing of the implements in the towing configuration. Second, a contact on the implement frame which engages the caster control assembly when the wheels are raised off the ground, cams the caster wheel to a preselected field-working position and prevents rocking of the wheel. Third, a bellevue washer on the caster control assembly limits shimmying of the wheel during transport.

One upright member is adapted to rigidly connect to the second implement. A central horizontal member has two opposed ends and front and rear sides. An upright member of the first parallel linkage is rigidly connected to the front side of the horizontal member. Ground engaging caster wheels are pivotally mounted on each end of the horizontal member. A second parallel linkage has two upright members with upper and lower portions. The upper portions of the upright members are pivotally connected by an upper lifting arm and the lower portions of the upright members are pivotally connected by a lower lifting arm.

Abstract: A planting tool for plants comprises a tube having a fixed beak half at its lower end. A hinged beak is hinged to the tube such that the fixed and hinged beak halves together form a beak capable of being pressed into the ground. The beak is then opened to make a hole in the ground for the plant, and is latched in the open position by the drawbar of a latching mechanism. The drawbar is attached to the hinged beak half and arranged to slide along an outside surface of the tube as the beak is opened and closed. The drawbar slides within a protective rail that is affixed to the outside of the tube to avoid being damaged or obstructed. The upper end of the drawbar extends above a reference edge of the rail when the beak is closed, and extends below that edge when the beak is open, thereby providing a visual indication of the condition of the beak. A handle for lifting and aiming the tube is adjustably attached to the rail to be adjustable to the height of the operator.

Abstract: A disk launcher includes a generally cylindrical housing having a handle depending downwardly therefrom. The housing further defines an interior cavity within which a launching shuttle is pivotally movable under the urging of an internal power spring. An opening in the housing is provided through which a disk may be inserted. A trigger mechanism permits the swept launching member to be locked in a launching position in which the inserted disk is positioned for launch. As the trigger mechanism is released, the launcher sweeps through a pivotal motion and hurls the disk outwardly through an exit slot in the housing. A magazine apparatus is provided which provides for the serially launching of a succession of disk objects.

Abstract: A bentleg plow apparatus has a forward direction and includes a mounting frame, an upper blade-like portion secured to the frame and extending generally downwardly, a first lower blade-like portion connected to the upper portion and extending downwardly and laterally to one side, a second lower blade-like portion connected to the upper portion and extending downwardly and laterally to the other side. Each lower portion has a rake angle with respect to the forward direction, the rake angle being defined, when the plow apparatus is moving horizontally on a horizontal terrain, as the angle made to the horizontal by the intersection of the respective lower portion with a vertical plane parallel to said forward direction, the rake angle being such that the lower portions tend to penetrate further into soil being plowed as the plow apparatus is moved in forward direction.

Abstract: An apparatus for trimming weeds and grass employs a prime mover to power a rotating cutting head. Three wheels are used to support the weight of the trimmer, and the prime mover is uniquely mounted to the trimmer such that lowering the cutting head is easily accomplished by tipping the trimmer. Cutting height is adjusted by way of an adjustable height arm, and a secondary handle is provided to receive and translate an upward urging force into a tipping motion. The cutting head can be easily removed and a brush, snow blade or blower can be installed thereto for accommodating a plurality of lawn care tasks.

Abstract: A hand-held tiller is adapted for use in loosening and breaking up the soil and is made up of a skid, an elongated handle extending forwardly of the skid with a drill motor at one end of the handle which is drivingly connected into a power transmission drive for operating a crank having a plurality of crank arms and vertically extending tines, the tines being sequentially driven by reciprocation of the crank arms into and out of the soil as the machine is drawn behind the operator.

Abstract: A garden tiller tine assembly for use with a tiller assembly which includes a drive shaft having a longitudinal axis of rotation includes a rotary blade aligned at a predetermined angle with respect to the axis of rotation. The planar body of the rotary blade is angled at a dihedral angle with respect to a plane normal to the axis of rotation. Upon rotation of the tine assembly about the axis of rotation, the rotary blade oscillates laterally from side to side along the axis of rotation to cut a wider path through the soil than conventional rotary blades.

Abstract: Blade mechanisms being operated along the ground have a tendency to draft into the ground unless some positive form of control is provided to prohibit the downdrafting of the blade. In the subject arrangement, a blade and linkage mechanism is provided for stopping a blade from drafting downward with respect to the ground. The linkage mechanism includes a tilt arm attached between a work vehicle and a top portion of the blade and a push arm attached between the work vehicle and a bottom portion of the blade. The tilt arm is movable relative to the vehicle through an arc which if extended intersects the push arm between its pivot connections. When the blade drafts downward, the different orientations of the tilt arm and the push arm corrects the downdraft due to the rear of a skid plate attached thereto being tilted with respect to the ground. The changing orientation of the skid plate with respect to the ground causes the front of the blade to raise with respect to the ground.

Abstract: A tubular fitting used for the connection of pipes, is formed such that if a main pipe and a branch pipe are inserted respectively within a through hole and a branch hole within the main fitting, and are coupled with the main fitting by means of the engaging body being engaged with the branch pipe and the branch pipe being engaged with the main pipe, the main pipe and the branch pipe can be securely connected by mechanical means without having to perform brazing operations.

Abstract: By providing the work blade of a grader with a hydraulic regulation system where pressure limiting valves (14, 15, 16, 17) guide pressure reducing valves (10, 11, 12, 13) a constant pressure regulation of the work blade is achieved so that the work pressure set by the operator from his cab is maintained almost independent of the irregularities of the underlying surface.

Abstract: A hydraulic or pneumatic shock-absorber for sporting and hunting bows is fitted, as a connecting element, between a stabilizing counterweight (spinner) and the bow in such a manner as to permit, between the counterweight and the bow, a movement which is damped in the direction of the shot, although the counterweight is secured rigidly to the bow vertically and horizontally to the direction of the shot. This leads to smoother launching of the arrow and to marked accuracy.

Abstract: A guide and control device for an agricultural machine subjected in operation to a high lateral thrust in relation to its direction of traction, such as a disk-type stubble-plough includes a guide and control system having at the front, a set of freely oscillating twin wheels the orientation of which for a change from a road-travel position to a soil-working position is controlled from a bar for coupling to a tractor. A carrying wheel is arranged in a central part of the frame, and at the rear thereof are arranged freely oscillating twin carrying wheels and furrow wheels controllable simultaneously from their road-travel position to their working position, and vice versa. The multiplicity of carrying wheels guarantees that sufficient grip with the soil is maintained permanently, thus preventing any lateral slip of the machine during passage over a movable obstacle, this also being assisted by the automatic orientation of the twin wheels by means of their freely oscillating mounting.

Abstract: A tool bar is provided with rotatable tool carrying sections having a quick release lock.

Abstract: An apparatus for supporting an arrow on an archery bow. The apparatus having an adjustable resilient finger member which is circumferentially adjustable on an annular frame member. The finger member being tapered so that the resiliency decreases in magnitude from the mounting end to the supporting end. The finger compensates for variable degrees of arrow distortion resulting in a maximum transfer of the energy from the bow string to the arrow.

Abstract: An improved disk harrow C-spring with a tapered cross section which reduces the compressive stresses in the inside radius and improves vertical and side-to-side flexibility. The curved portion of the C-spring has a constant cross section at the top and around three-fourths of the bend. At a location on the bend 45 degrees down from the horizontal, the thickness tapers to a location forward of the bearing hanger. The cross section is constant from the end of the taper to the end of the spring. The tapered cross section allows a thicker section to be used on the most highly stressed areas in the upper quadrant of the curved portion of the C-spring. The lower quadrant taper results in uniform stress distribution along the entire C-spring with the maximum compressive stress on the inside radius reduced substantially over a conventional C-spring. In addition, the tapered design provides an increase in both vertical and side-to-side flexibility for improved operation in rocky soil.
