Patent number: 4786204Abstract: A clamping device for exerting clamping forces in two directions to a shank between a pair of spaced clamping members having a transverse stop. The device includes an elongated bolt like body having a pair of axially spaced sections, a head at one end and external threads on an opposite end portion with a nut on the threads for applying a first clamping force to the spaced members. An eccentric section between the shaft sections applies a transverse clamping force to the shank. A pair of flat plates forming the clamping members has two spaced clamping devices and is arranged to slidably clamp to a variety of movable supports. A pair of spaced clamping plates are affixed to the end of a longitudinal frame with the option of a shim to accomodate shanks of smaller sizes.Type: GrantFiled: February 24, 1986Date of Patent: November 22, 1988Assignee: The Eversman Mfg. CompanyInventor: Bruce H. Mayeda

Patent number: 4753297Abstract: An agricultural tool assembly includes a rotary disk mounted on a lower end of a rotary spindle. A mount for the spindle includes a shank adapted to be received in the vertical slot of a clamp and a sleeve for rotatably supporting the spindle. The sleeve is connected to the shank by spaced side plates connected to the sleeve with a lower pivot member and an upper fastener extending through arcuate slots in the spaced plates. A cultivator implement has front and rear disk gangs and a rear centered tool assembly. An onion undercutting implement has a front tool bar with front tool assemblies clamped thereto and a rear tool bar with rear tool assemblies clamped thereto.A tool assembly for material distribution has a spindle with a through hole, a swivel fitting at the inlet and a flared section at the outlet. Crop cutting and windrowing apparatus has pairs of tool assemblies tilted in and down toward the crop row and forwardly and down.Type: GrantFiled: April 22, 1986Date of Patent: June 28, 1988Assignee: The Eversman Mfg. CompanyInventors: Bruce H. Mayeda, Robert R. Owen

Patent number: 4660653Abstract: An agricultural tool assembly (21) disclosed is used with a planter attachment. Assembly (21) includes a rotary disk (23) mounted on a lower end of a rotary spindle (25). An offset mount for the spindle includes a shank (41) adapted to be received in the vertical slot of a clamp (22) and a sleeve (45) offset from the shank for rotatably supporting the spindle. The sleeve is connected to the shank, using a bifurcated portion comprised of spaced plates (47, 48) connected to the sleeve with a lower pivot member (52) and an upper fastener (58) extending through arcuate slots (61 and 62) in the space plates. The planter attachment has a support frame that disposes the tool assembly (21) ahead of the planter (230) to cut the old crop prior to having the planter deposit the seed.Type: GrantFiled: November 21, 1985Date of Patent: April 28, 1987Assignee: The Eversman Mfg. CompanyInventors: Bruce H. Mayeda, Robert R. Owen

Patent number: 4585073Abstract: An agricultural tool assembly (21) disclosed is usable on a variety of implements in place of shovels, blades, tines or sweeps and on novel cultivating or crop root undercutting implements and the like. Assembly (21) includes a rotary disk (23) mounted on a lower end of a rotary spindle (25). An offset mount for the spindle includes a shank (41) adapted to be received in the vertical slot of a clamp (22) and a sleeve (45) offset from the shank for rotatably supporting the spindle. The sleeve is connected to the shank, using a bifurcated portion comprised of spaced plates (47, 48) connected to the sleeve with a lower pivot member (52) and an upper fastener (58) extending through arcuate slots (61 and 62) in the spaced plates. The disk may be tilted at a selected angle or set horizontally and for some applications may be set to release in the event the blade strikes an obstruction. A cultivator implement has front and rear disk gangs (108, 109, 114, 115) and a rear centered tool assembly (21).Type: GrantFiled: August 24, 1984Date of Patent: April 29, 1986Assignee: The Eversman Mfg. CompanyInventors: Bruce H. Mayeda, Robert R. Owen

Patent number: 4373590Abstract: Tilling apparatus disclosed has a rotor shaft with axially spaced multiple tine and hub assemblies having hoe portions of adjacent tines overlapping one another. The apparatus is constructed as a central section and has wing sections pivotally connected to the central section. A first pivot axis for each wing section is the same horizontal plane as the rotor shaft. A first link connects at its lower end to the wing section at the first pivot axis and at its upper end to the central section at a second pivot axis. A thrust link driven by a two-way cylinder moves the wing section about the first pivot axis and then about the second pivot axis. Each tine hub is made in two half-bodies supporting two tines at 90 degrees, with a recess to turn adjacent hubs 30 degrees to one another. Each tine has a bevel on the outer side and a smooth hard surface on the inner side.Type: GrantFiled: April 25, 1980Date of Patent: February 15, 1983Assignee: The Eversman Mfg. CompanyInventor: Michael C. Wittrock

Patent number: 4236587Abstract: Land leveling apparatus includes a leveling attachment drawn by a tractor with the attachment having pivotally connected side blade sections on a central blade section affording a substantially greater leveling capacity. The side blade sections fold up to reduce width during transport and have a power-driven linkage arrangement for each blade section that moves and positions the blade sections and locks them in the lowered working position, together with upper and lower level adjustments for the side blade sections. A hitch assembly facilitates quick coupling to a crossbar carried by the lower links of the tractor linkage and is pivotally joined to the central blade section so as to facilitate rear tractor wheel movement independently of the scraper blades.Type: GrantFiled: April 23, 1979Date of Patent: December 2, 1980Assignee: The Eversman Mfg. CompanyInventors: Benjamin A. Shader, Bruce H. Mayeda
