Inventor: REQUATE JOHN
IPC: A01K1/06
Filed: 2002-03-18
Abstract: The application contained herein pertains to the control of animals through a mechanical device that increases the safety of the handlers, and reduces the stress placed on the animals. The head gate assembly uses pressure applied to an animal's neck to restrain the animal during times of inspection. This application uses the momentum of the animal to trigger the closure of the head gate while a self ratcheting latch ensure closure and locking of the head gate assembly. Once captured, the animal is serviced. Releasing the animal through a rear control bar allows the animal to proceed forward through an unobstructed route while at the same time, preparing the gate for the next trigger. Once cleared, the following animal entering the gate is presented a clear unobstructed path resulting in reduced stress.

Abstract: A manually operated apparatus (35) for removal and insertion of a tool holder (20) to and from a tool pocket (12) of a magazine (10) includes two components - a multi-function insertion/removal tool (37), and a pivot bracket (38). The multi-function tool generally comprises an elongated bar (45) having a tool holder removal element (40) at one end (47) and an insertion element (50, 48) at the opposite end (61). The removal element can constitute a known pry tool having a fork portion (41) configured to facilitate insertion between the rim (13) of the tool pocket and the underside of the circumferential flange (23) of the tool holder. The insertion element of the multi-function insertion/removal tool comprises a pivot block (48) and a pressure plate (50). The pivot block includes a pivot pin (52) projecting therefrom that is configured for pivoting engagement within a channel (56) defined in the pivot bracket. The pivot bracket is mounted to the housing (17) of the tool magazine at a manually accessible location relative to the tool pockets with the open end of the channel facing away from the tool pocket. When the pivot pin of the insertion/removal tool is disposed within the channel of the pivot bracket, the pressure plate is situated over a portion of the circumferential flange of the tool holder when the holder is loosely disposed within the tool pocket. The elongated bar of the tool can be used as a lever arm to pivot the tool about the fulcrum point defined by the pivot pin and pivot bracket.  As the elongated bar is manipulated, the pressure plate is pivoted downward, bearing against the circumferential flange of the tool holder with sufficient force to overcome the pocket spring force operating against the head (21) of the tool holder.

Title: Actuation system for highly underactuated gripping mechanism
Inventor: LALIBERTE THIERRY
IPC: B25J15/00
Filed: 2001-01-24
Abstract: This invention provides an actuation system for a highly underactuated gripping mechanism with ten degrees of freedom, which requires only two actuators, one for actuating the opening and closing of three fingers and the other for the orientation of two rotatable fingers with synchronization. Underactuation between the fingers is provided by a one-input/three-output differential which is associated with an orientation mechanism so that an orientation-fixed finger is deactivated when the two orientatable fingers are rotated to face each other for a pinch grasp.  Each finger is enabled to be self-locked in its closing and opening action when the power is off. In one embodiment of the invention, a planetary gearing system is used for the differential. In another embodiment, a Geneva mechanism is used for the orientation transmission, and a fastening interface using an indexing ring is provided to connect an external driving apparatus.
