| A composite working tool, for example a ground engaging tool of an agricultural implement, features a body composed of a first material and an insert composed of a distinct second material of greater hardness than the first material to define wear resistant surfaces of the tool. The tool body has an opening recessed thereinto from an exposed exterior surface fully surrounding the opening on all sides thereof, and the insert is attached to the body in a position at least partially received within the opening, for example by brazing. The increases the wear life of the body and provides greater mounting strength over surface-mounted wear inserts of the prior art. | ||||||

| 147 | Vertical Tine Tillage Tandem Frame And Inter-related Secondary Tillage, Planting and Fertilizing Machine | US12979040 | 2010-12-27 | US20110155401A1 | 2011-06-30 | James R. Martindale; Daniel R. Martindale |
| This tillage machine disclosure utilizes the original Huxley (1983) patented aerator tine geometry with special features which are different from those patented by Martindale (U.S. Pat. No. 6,854,525). These features are disclosed here in a series of different arrangements within machine frame designs. There are two different embodiments of the enhanced tine design.The frame designs disclosed protect the farmer from maintenance neglect and unintentional misuse or oversight of the tine technology limitations which have led to inconsistent performance in previous framing presentations. These designs result in greatly reduced machine lifetime costs of soil-engaging tines. A wide range of power requirements and concomitant amounts of soil fracturing in relation to the number of tine perforations is achieved to effectively reduce soil erosion potential as a result of the tillage operations.The embodiments disclosing the roller assembly provide for the elimination of multitudinous small fasteners to retain the aerator tines. The advantageous helical phasing and re-phasing disclosed create tine insertion alignment to dramatically reduce rear tine wear rates because the rear tines use the insertion hole created with the front rank of the machine. Unique to this disclosure is the ability of one of the roller embodiments to insert intermediate load carrying bearings into the roller assembly without altering the helix. The tine retention system disclosed permits individual tine replacement without total disassembly of the roller assembly while using an arbor bolt to retain the components in proper tension and helical arrangement.The arbor bolt retention system for agricultural tillage tools has only seldom been attempted for tine type soil aerators. This disclosure includes two different embodiments of the technique. One consists of using multiple shapes of surfaces designed to present part mass in the appropriate places to control movement and attempts of dislodging and at the same time allow individual tine replacement should breakage occur.The second embodiment consists of using dowel or locator pin methodology for affixing soil engaging tines to a rotating member or arbor bolt shaft using a series of identical and reversible parts. By using different assembly configurations, optimal adjacent tine intervals and assorted uniform helical rephrasing arrangements are achieved.A central hub in this embodiment is located circumferentially to the arbor bolt which can have multiple shapes other than round. The internal geometry of the hub conforms to the arbor shaft shape to provide propulsion faces. This same hub is outfitted with external teeth or other geometric shapes to mesh with clamping rings which are machined to receive dowel pins. The dowel or locator pins in the ring then pass through or integral with the tine base or locator pin bores to the adjacent clamping ring on the opposite side of the tine. By altering the number of coincident mating surfaces on the hub and clamping ring, a multitude of different uniform helical arrangements is possible.Since the helical positions of groups of tines can be determined by the central hub, clamping ring and tine retaining dowel pins, it is practical to locate shaft support bearings at advantageous random intervals throughout the length of the arbor bolt assembly without disrupting the helical tine arrangement or sequence.This embodiment discloses components which are inexpensively produced with plasma or laser burning equipment and stamping thereby avoiding expensive tooling required to create castings. As in the first embodiment of the arbor bolt embodiment, individual tine replacement is accomplished by parting the clamping rings enough to remove the tine and the retaining dowel pins or integral locator pins in the tine base.This roller and tine retention system is presented in direct support of tandem frame tine type aerator technology which supports wider than normal tine spacing which is also adjustable by selection of differing spacer lengths. It presents a spacer technology which permits machine size increments of 1.5 meters or 5 feet. These arbor system spacers permit optimal construction of the helical assemblies for irregular groupings while still assuring smooth, vibration-free and low-ballast requirement, full-depth penetration of soil.Since the tine action is different in the tandem frame design, this application discloses a tine specifically for this fastening system which is more cost effective by reducing mass and yet very resistant to breakage. Several tine features disclosed offer more strength, superior penetration in adverse conditions and superior crop residue resizing capability while maintaining the Bannan (1983) performance features. Eliminating the use of hundreds of fasteners, the maintenance required and the sheer aggravation of removing and replacing the fasteners when tine replacement is required is noteworthy in itself.The frame design incorporates additional technologies for crop residue re-sizing, soil seedbed shaping and other secondary vertical tillage, creating a one-pass total tillage, broadcast and banded fertilizing and planting machine which is appropriate for forage, vineyard, orchard, pastureland and row-crop production systems in widely differing ecosystems. The machine disclosed requires less framing steel and ballasting for soil penetration thus extending life of all component parts such as bearings and other suspension system components while reducing production costs for raw materials. | ||||||

| 155 | Clamping arrangement for a flexible earth-working tine | US721104 | 1976-09-07 | US4047823A | 1977-09-13 | John W. Mydels |
| A flexible earth-working tine is releasably fastened to a transverse tool bar by use of a pair of identical clamping parts, a keeper element and releasable fastening means. The clamping parts are disposed on vertically opposite sides of the tool bar and have corresponding front ends with aligned vertical openings to receive a bolt extending downwardly therethrough, the bolt also connecting with the mounting end of the flexible tine. Corresponding rear ends of the clamping parts are maintained in assembled relationship by a keeper element and the flexible tine extends from its mounting end in encircling relation to the tool bar with an upwardly extending portion passing between transversely spaced fingers extending rearwardly from the upper and lower clamping parts. The upwardly extending portion of the earth-working tine disposed between the fingers serves to maintain the keeper element in its operative position on the fingers. The rearwardly extending fingers of the clamping parts prevent transverse movement of the tine and a single fastening bolt, with its cooperating nut, maintains the earth-workig tine and clamping parts in rigid clamped relation on the tool bar. | ||||||
| 156 | Ground engaging implement tooth and mounting means therefor | US3710872D | 1970-08-11 | US3710872A | 1973-01-16 | KOVAR H |
| A ground engaging implement tooth and mounting means therefor comprising an elongated rod element having opposite ends and having a portion of its length adjacent one end formed into a coil having a plurality of convolutions disposed on a horizontal axis. The end of the rod adjacent the coil terminates in an anchor portion which is adapted to be secured to an implement frame by means of an anchor bolt extending therethrough. The other end of the rod extends away from the last convolution on the other end of the coil in a vertical direction to form a straight ground engaging portion. The convolutions of the coil decrease in diameter from the anchor portion to the ground engaging portion so that deflection of the ground engaging portion will tend to be resiliently absorbed in the coil by more than the last convolution thereof and so that the ground engaging portion will normally be free from engagement with an implement frame upon deflection of the ground engaging portion.
