Title: Mounting for agricultural toolbars and tubes of differing cross section
Inventor: NOONAN JAMES THOMAS
IPC: A01B35/30
Filed: 1996-12-05
Abstract: Tube mounted bracket structure for a toolbar or similar tube with a rectangular cross section includes a bracket having a tube abutting flange with an aperture offset from an elongated slot.  A rotatable insert has an inwardly directed and elongated projection conforming to the shape of the elongated slot and an aperture located at one extremity of the projection.  The aperture extends through the projection and through an integral washer portion which defines an enlarged shoulder area for contacting the tube abutting flange when the insert is positioned in the slot.  The elongated projection generally fills the entire slot with the exception of the aperture, thereby presenting a relatively solid bolt receiving area for mounting a U-bolt or similar bolt structure.  For a toolbar or tube having relatively large cross section, the insert is positioned in the slot to provide maximum offset from the flange aperture.  If the bracket is attached to a toolbar or tube with smaller cross section, the insert is rotated 180 degrees from the position for the first cross section so the projection aperture is positioned to provide minimum offset from the flange aperture.

Abstract: A rack for supporting small articles or aligning wires. The rack may either be hung on a vertical surface or seated on a horizontal surface. The rack includes an elongated housing with an elongated entrance slot formed in its front wall. A multiplicity of retainer loops are supported side-by-side on the elongated housing with their bight portions in front of the housing to receive and support the small articles and to align the wires. The retainer loops are formed with tails which hold them in the elongated housing and have slots which fit over a rib in the housing to prevent twisting of the loops. The end of the rib may be enlarged to be received in complementary shaped slots in the loops to increase pull out resistance of the retainer loops. When small articles or wires are inserted between pairs of retainer loops, the tails of the loops will slide along the rib to accommodate articles of varying cross sections while maintaining essentially uniform pressure against the articles being held. The rack is formed so that it may be supported by fasteners, suction cups or adhesive, including stick wax blocks of adhesive.

Inventor: OTT MICHAEL J
IPC: H01R13/56
Filed: 1997-11-12
Abstract: A multi-link boot assembly has a number of separate links which can be connected to form a flexible boot assembly capable of maintaining a predetermined bend radius as off-axial loads are applied, thereby effectively dispensing stresses along a cable as the cable is flexed or bent. Each link of the multi-link boot assembly includes a body portion defining a lengthwise extending bore for receiving the cable. The body portion extends between first and second opposed ends and generally includes a female section at the first end and a male section at the second end. The female section defines an opening for receiving the male section of another link during the assembly of the multi-link boot assembly. In order to connect each link with another link to form the flexible boot assembly, each link includes a connecting element at each of the first and second opposed ends which cooperably engages a corresponding connecting element of an adjacent link. As a result of the mechanical interconnection of the links of the multi-link boot assembly, the multi-link boot assembly will permit the cable to readily bend or flex until the predetermined minimum bend radius of the cable is reached, at which point the boot assembly will prevent further bending of the cable even in instances in which increased off-axial loads are applied to the cable.
