Patent number: 4826229Abstract: An improved portable cable release mechanism for mounting on the deck of a tow boat, tug, ship or dock and used to tow and dock barges, boats and ships, which mechanism is designed to receive one end of a tow cable or docking cable in order to secure and selectively release the vessels. The cable release mechanism includes a pelican hook pivotally attached to a frame which can be removably mounted on a dock or secured to the deck of a tow boat, ship or barge by means of a clevis plate. A sliding keeper normally secures the pelican hook in closed configuration in the frame and release of a towing or docking cable from the pelican hook is automatically effected by activating an air or hydraulic cylinder having a piston provided in cooperation with the keeper ring. This action extends the cylinder piston and forces the keeper from engagement with the pelican hook, allowing the pelican hook to pivot rearwardly responsive to the load on the cable.Type: GrantFiled: April 3, 1987Date of Patent: May 2, 1989Inventor: Gregory L. Smith

Patent number: 4826260Abstract: An air-adjustable shock absorber is pivotally connected at its ends to first arms of a front end of a back crank arm system, which are pivotally mounted to the vehicle chassis at the front and back of the same between the upper and lower runs of the endless track of the vehicle. The second arms of the front and back crank arm systems are connected to the front and back portion of the slides which engage the upper surface of the ground-engaging run of the endless track. The air pressure within the shock absorber unit biases the two crank systems in a direction so as to move the slides downwardly from the vehicle chassis. An air circuit system enables the driver to control the air pressure depending on the load carried by the vehicle. The crank systems are such that a greater proportion of the load is carried by the back of the suspension.Type: GrantFiled: November 9, 1987Date of Patent: May 2, 1989Inventor: Aime Plourde

Patent number: 4819977Abstract: Device to be used, as the preferred embodiment, for dog feces retrieval and bagging. The simplicity of construction and operation allows use by persons of all ages without undue effort or bending. The retrieval and bagging and tying and containing of waste material in one operation has not heretofor been realised. The device consists of a hollow tube with eight flexible fingers on one end, a removable sleeve over the tube, and a lanyard and cap at the other end, and a plastic bag with rubber band. When the plastic bag is placed over the exposed fingers, the bag end folded back and fixed with a rubber band over the sleeve, the sleeve is then moved forward over the exposed and bagged fingers. Retracting the sleeve thus exposing the bagged fingers, the device is placed over the waste material to be retrieved. By moving the sleeve forward the fingers are caused to draw in the waste material, into the bag, and into the tube, the rubber band slipping over the fingers and tying the bag.Type: GrantFiled: August 24, 1987Date of Patent: April 11, 1989Assignee: Alfred SitesInventor: Robert E.

Patent number: 4818029Abstract: An anti-theft device for a pneumatic-tired vehicle, of the kind comprising means (4) for automatically deflating a tire (5) of the vehicle and deflating the tire (5) when the device is actuated by control means (2) and the vehicle is in motion, the deflating means (4) being moved by the centrifugal force of inertia when the corresponding wheel (3) rotates whereas they are inoperative in other cases, characterized in that the deflating means (4) comprise movable means for closing at least one orifice (7) through which air under pressure can escape from the tire (3), the movable closing means normally sealing the orifice (7) when the device is inoperative and/or the wheel (3) is stationary, whereas they unclose the orifice (7) and allow air to escape when the device is actuated and as soon as the centrifugal force of inertia reaches a sufficient value to move them.Type: GrantFiled: November 14, 1986Date of Patent: April 4, 1989Assignee: Compagnie Financiere Saint NicolasInventors: Franck Mourot, Jean-Dominique Dana -
Patent number: 4815781Abstract: An industrial robot hand for material handling. A fixed frame is connected to an arm of an industrial robot. A movable frame having a rectangular plan shape is horizontally movably supported on the fixed frame. Two guide rods are vertically attached to each of the four sides of the movable frame. A tapered guide extends downwardly from each of the guide rods. Sandwiching plates are provided on two opposite sides of the movable frame. Each sandwiching plate is pivotally attached to the movable frame by a horizontal axis at the central portion of the sandwiching plate. Engaging members project inwardly from the lower inner surface of the sandwiching plates to hold the material to be handled. Rollers and roller guides restrict the movement of the movable frame on the fixed frame. A driving mechanism pivots the sandwiching plates to bring the engaging members into engagement with the material.Type: GrantFiled: September 14, 1987Date of Patent: March 28, 1989Assignee: Kabushiki Kaisha Yakult HonshaInventors: Shinichiro No, Minao Kimura

Patent number: 4815782Abstract: A grappling device comprises an arm formed from a closed ended, inflatable tube (5) having a plurality of generally parallel, longitudinally spaced bands (15) disposed therearound for limiting the radial distention of the arm when inflated. A longitudinally inelastic, laterally flexible band (20) disposed on a surface of the arm causes the arm, when inflated, to wrap around an object to be gripped. The extent of the inflation of the arm determines the gripping force and geometry of the device.Type: GrantFiled: December 8, 1986Date of Patent: March 28, 1989Assignee: United Technologies CorporationInventors: Preston S. Craig, Jeffrey A. Fisher

Patent number: 4815780Abstract: The invention provides an apparatus for detachably connecting a tool to a manipulating device, e.g. an industrial robot. The apparatus includes a tool holder and a coupling member fastened to the robot. The coupling member has a free frontal surface on which the tool holder rests. A plurality of air channels and electric contacts merge into the free frontal surface in a peripheral region thereof. Four projecting centering pins are provided in the center of the free frontal surface. The tool holder is provided with correspondingly located air channels and electric contacts as well as with a centrally arranged centering disc which is rigid in circumferential direction and axially resilient. The disc has apertures in which the centering pins enter when the tool holder is fixed to the coupling member. Thus, the tool holder is precisely centered and all pneumatic and electric connections are automatically established.Type: GrantFiled: March 22, 1988Date of Patent: March 28, 1989Assignee: Erowa AGInventor: Basil Obrist
