Abstract: A device for clamping a rod to stop axial and/or rotative movement between the rod and the device. The device includes pressure and clamp units, the clamp unit having a bushing fixed therein and provided with a radially resilient center section normally sized to permit movement of the rod therein. The pressure unit has an actuating piston normally held under fluid pressure in one position but movable under spring pressure toward a second position should the fluid pressure be lost or released. Such movement results in the application of pressure to the bushing to radially deflect its center section inwardly into clamping engagement with the rod to stop its movement. The center section remains clamped on the rod until sufficient fluid pressure is applied to the actuating piston to move it back to its first position thus permitting radial expansion of the center section to release the rod for movement.

Abstract: A wildlife feeder is provided comprising a housing for holding wildlife feed and a separable mounting subassembly for releasable attachment of the housing to a support structure. The housing comprises a base from which extend upstanding walls. The base has a peripheral skirt and an underside with anchor structures for placement of the free ends of a wire form wildlife perch structure. The wire form extends a predetermined distance out from the base outer periphery and is constrained from downward tilt with retention notches in the peripheral skirt. The mounting subassembly comprises a bracket having engagement elements for insertion into slots in the back wall of the housing. The engagement elements include releasable retention tabs so that the housing can easily be removed from the bracket for food resupplying, cleaning and repair. The bracket includes a hinged roof structure. When the housing is attached to the bracket, the roof rotatably encloses the housing open top.

Abstract: A modular birdhouse in accordance with the present invention includes a support pole, a collar, at least one wire form and at least one nest module. First, the collar is slidably connected to the pole. The wire form has a square shape, and the ends of the wire form are upturned and inserted into corresponding openings in the collar. The collar includes coordinated flanges with fasteners that fix the wire forms to the collar. Two or more collars can be interconnected in a stacked manner to create tiers of nest modules. Each nest module has a plurality of connector slots. For attachment, the nest module is positioned within the square shape of the wire form and then rotated until the connector slots of the nest module engage the wire form. A porch structure interconnects the wire form to the nest module to prevent further rotation and disengagement of the nest module. Nest modules may be added or removed from the wire forms as desired by the operator and without the use of tools and/or implements.
