  • Patent number: 9049956
    Abstract: A cart suitable for supporting a grill, including a grill bowl. The cart has two union members with curved channels for receiving tubular, U-shaped frame members. The union members may be in the form of two similar (but not necessarily identical) halves joined together to enclose the frame members. The tubular channels of the union members resist movement (such as twisting and tilting) in at least two directions. The union members lock the frame members in place with internal protrusions that fit into mating depressions or holes in the frame members. Extra rigidity is added to the cart by one or more side tables which are structural members as well as functional tables. The side tables thus serve as cross-members between two frame assemblies. The grill's lid can easily be tilted back to rest in place on lid supports underneath the bottom edge and contact points on the side tables.

In the subject arrangement, a coupler is provided and has a tooth mounting portion with a nose portion having a pair of load bearing surfaces, a pair of spaced apart grooves, a pin opening, and a transverse opening that is oriented perpendicular with and in intersecting relationship with the pin opening. The coupler also includes an adapter receiving portion which has a cavity defined therein with a pair of spaced apart load transferring surfaces located in the cavity generally adjacent the bottom thereof and a retainer opening defined therein in intersecting relationship with the cavity.

  • Patent number: 5423138
    Abstract: Tooth assemblies having a tip attached to an adapter by a retaining mechanism is normally utilized in order to readily replace the tip which is a high wear element. It is advantageous to have a tip that due to its interface with the adapter allows effective transfer of forces being subjected to the tip directly to the adapter without creating undesired resultant forces trying to force the tip from the adapter. In the subject arrangement, a tip has a cavity with a load bearing bottom surface at the bottom of the cavity and a pair of parallel spaced apart load bearing surfaces adjacent thereto. The tip also has an ear extending from one of the side walls thereof, a longitudinally extending groove defined therein, and a pin receiving opening 56 defined therein that extends through a top wall, the one side wall and a bottom wall of the tip and intersects the longitudinally extending groove.

  • Patent number: 5325615
    Abstract: 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.

  • Patent number: 5215150
    Abstract: 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.
