Patent attributes
An expandable vibrator bracket for attaching a car-shaker vibrator to a female receptacle attached to a railroad car to be vibrated. The expandable bracket includes: a vibrator mounting member, a leg member, and a wedge base member. The vibrator mounting member supports the vibrator. The wedge base member further includes a first end, a second end, a first side, and a second side. The wedge plate includes an attaching end, a distal end, an interior side and an exterior side. The attaching end is coupled to the first end of the wedge base member for allowing the distal end to selectively move with respect to the second end of the wedge base member when acted upon by a spreading or expanding force. The second side of the wedge base member and the exterior side of the wedge plate simultaneously abut opposite interior surfaces of the female receptacle during selective urging by the spreading force for holding the expandable vibrator bracket in the female receptacle. The spreading force may include a linear type of wedge, a rotary wedge, springs. The subsequent removal of the spreading or expanding force allows for the removal of the collapsed vibrator bracket from the female receptacle.
