Abstract: A clamping apparatus for use on a material handling machine. The clamping apparatus includes a mounting bracket which is fixed to the material handling element of the machine, a connecting bracket which is pivotally mounted on the mounting bracket and a clamping arm which is pivotally mounted on the connecting bracket. The connecting bracket is pivotally mounted on the mounting bracket between an active position and a storage position. When the connecting bracket is in the active position, the clamp arm is hydraulically actuated within a vertical plane between an upper non-clamping position and a lower clamping position. When the connecting bracket is in the storage position, the clamp arm extends horizontally in an out of the way position. The connecting bracket is maintained in the active position by first retaining means and in the storage position by second retaining means.

Abstract: A hand truck for lifting and transporting objects. The truck includes an elongated frame attached to a wheel assembly. A carriage is mounted on the frame to travel the length of the frame. The carriage includes a load bed that extends across the frame, and at least one protrusion located below the load bed that extends above the load bed. A seizing arm is pivotally attached to the carriage above the load body and has a seizing arm with a grip point directed toward the load body. The seizing arm has a stem that extends beyond the pivot point attachment opposite the seizing arm body. A winch with cable are attached to the top of the frame. The free end of the cable is attached to the seizing arm stem. Retracting the cable causes the seizing arm to pivot so the grip point is forced against as object located on the carriage. The force of the seizing arm is sufficient to secure the object between the grip point and the carriage.

Abstract: Apparatus for use on a front-end loader bucket including a telescopically-extendable clamp arm operating in conjunction with a solid link.

Abstract: System for packaging cup-like coffee filters, consisting of nesting the filters so that their upper edges form a frusto-conical surface and of providing a tab associated with each filter, so that the innermost filter can be readily separated from the others.

Abstract: Material handling apparatus, including a bucket and a clamp arm mounted on the bucket, the clamp arm being movable from an operative position, where it cooperates with the operative edge of the bucket in handling material, to a storage position where it is located outside of the bucket.

Abstract: Control system including an hydraulic valve and cylinder and including apparatus for indicating to the operator the exact point when pressure fluid starts to flow to the cylinder.

Abstract: This invention relates to a material handling apparatus and, more particularly, to apparatus for use in industrial and excavating operations, wherein an articulated vehicle is associated with an accessory tool.
