Patent number: 5325615Abstract: An attachment, adapted to mount to the front edge of an excavating bucket, includes a working structure and a base. The front edge of the bucket defines an inner surface, an outer surface, and a beveled surface oriented at an inclination to the inner and outer surfaces. The base of the attachment includes a single leg or pair of legs having opposed engagement surfaces. The engagement surfaces on the two legged attachments diverge from one another to define a gap therebetween for receiving the lip of the bucket. One of the engagement surfaces defines a convex surface which enables the attachment to be mounted to a variety of different buckets irrespective of the inclination of the beveled surface of the front edge.Type: GrantFiled: March 29, 1993Date of Patent: July 5, 1994Assignee: ESCO CorporationInventors: Brian J. Hutchins, William C. Johnston, Timothy L. Mayfield

Patent number: 5215150Abstract: A subsoil plowing implement having winged subsoil plows that break and lift the soil thereby loosening said soil. The plows are mounted so that an upper surface of the wing of the plow may be oriented at varying degrees of incline to horizontal. Spikes are located at a leading edge of the wing and a shank so that said spikes precede the wing and shank through the soil. The spikes initially break the ground and reduce the resistance that the wing and shank experience as they progress through the soil. A bevelled and sharpened deflection strip fixed to a leading edge of the shank making said shank more knifelike and allowing it to cut through the soil with reduced friction. By varying the arrangement and orientation of the plows, areas of loosened soil with different cross-sectional shapes are created.Type: GrantFiled: February 19, 1991Date of Patent: June 1, 1993Assignee: Phares & Wilkins Manufacturing, Inc.Inventor: Walter B. Wilkins

Patent number: 5165487Abstract: The point is adapted to fit onto the forwardly projecting mounting wedge of a tillage shank and has a downwardly and forwardly inclined, elongated crown provided with a transverse, sharpened tip at its lower front end. An underslung transverse wall looped under the crown at the front end of the point defines a rearwardly opening socket that matingly receives the apex of the mounting wedge of the shank, and depending sidewalls on the crown adjacent its opposite lateral edges rearwardly of the underslung wall serve to present a protective trough on the underside of the crown that matingly receives the upper surface of the mounting wedge so as to protectively cover otherwise exposed side portions of the wedge and thus shield such areas from exposure of abrasive soils.Type: GrantFiled: March 15, 1991Date of Patent: November 24, 1992Assignee: Acra-Plant, Inc.Inventors: Robert A. Williams, William A. Bell

Patent number: 5149087Abstract: The present invention entails a utility golf accessory in the form of an elongated rod having a handle on one end and a ground penetrating fork on the other end. The ground penetrating fork functions to repair ball marks and divots. Pivotally connected to the handle end of the elongated rod is a hook which functions to support one or more golf clubs that are unattended. In particular, the elongated rod can be anchored in the ground and one or more golf handles from golf clubs can be leaned against the hook such that the golf club handles are supported in an inclined fashion adjacent the ground penetrating ground accessory.Type: GrantFiled: February 10, 1992Date of Patent: September 22, 1992Inventor: James W. Thompson, Jr.

Patent number: 5110123Abstract: A golf tool combination (20) of a divot repairer (22) and a ball marker or spotter (26) comprises a pair of markers joined together as a unit (24) by legs (42) with a lip (48) of one marker engaging indentations (38) in the other marker. A space (28) provided between the markers receives and holds divot repairer (22) between the markers in the space. Prongs (62) in repairer (22) resiliently engage curved surfaces (52) on legs (42) to ensure that the divot repairer is held with the assembled together markers. A V-shaped portion (64) joins the prongs and enables a user to grip, position and manipulate the repairer in a relatively pressure-free manner when used to repair and replace divots.Type: GrantFiled: June 24, 1991Date of Patent: May 5, 1992Inventor: George G. Larson

Patent number: 5042812Abstract: A rake storage system is disclosed for use in close proximity to golf course sand traps. This system includes a storage tube which is insertable in the ground and a golf course rake whose handle slides into the tube so that only the rake head is exposed. Also included in this system is a sleeve which slides into the tube to provide an indexing mechanism which automatically rotates the rake to a desired orientation as the rake is inserted in the tube. Indexing is accomplished by a tab incorporated onto the rake handle engaging a slot incorporated within the sleeve. In another embodiment, the rake handle has a uniquely shaped upper portion which engages in a sleeve with a like shaped upper portion so that the rake is at the desired orientation when the rake is installed in the tube.Type: GrantFiled: November 26, 1990Date of Patent: August 27, 1991Inventor: Stan Tillman
