  • Patent number: 9546021
    Abstract: A method and apparatus for storing, transporting and distributing kegs. The apparatus comprising a keg shelving assembly with two or more stacked shelves. The shelves containing individual keg slots formed by two or more horizontally disposed rails. Stored kegs within the keg slots are accessed by a vertical sliding frame within a fixed frame vertical guidance assembly. A hinged platform is fixed to the vertical sliding frame having an open, horizontal position and a close vertical position relative to the vertical sliding frame. The apparatus further comprises a braking assembly that utilizes the downward force created by a load on the platform, to create a braking action opposing the downward force. This action allows a user to easily and efficiently lower a keg from one of the stacked shelves.

  • Patent number: 7717665
    Abstract: A method and apparatus for stacking first and second loaded pallets includes a pallet stacker that defines a stationary stacking location. A first loaded pallet is conveyed to the stationary stacking location. A pair of pallet lift carriages are vertically adjustable at the stationary stacking location to selectively engage the first loaded pallet and raise it to a temporary holding position. A second loaded pallet is conveyed into vertical registration with the first loaded pallet. The first loaded pallet is then vertically adjusted into stable stacked relation with the second loaded pallet, and the pallet lift carriages disengage the first loaded pallet. The first and second loaded pallets, in stable stacked relation to each other, thereafter are discharged from the stationary stacking location.

  • Patent number: 7650969
    Abstract: An elevator system includes a safety device strategically positioned within a hoistway to provide overhead or under car clearance during an inspection procedure, for example. An example safety device includes a triggering member that is selectively moved into a stopping position to engage a safety brake for preventing movement of an elevator car beyond a selected vertical position. The triggering member is selectively moveable in an automated manner between a retracted position and a stopping position. When the triggering member is in a retracted position, it has no effect on normal elevator system operation. When the triggering member is in the stopping position, it provides for maintaining adequate clearance between an elevator car assembly and another surface or structure within an elevator hoistway.

  • Patent number: 7278517
    Abstract: A device provides an elevator installation with a shortened car travel path to establish a temporary protective space below and/or above the car upon activation of the car safety brake device. The speed limiter cable is limited, independently of the speed limiter, in a travel path by a switchable stop device. This limitation causes an actuation of the car safety brake device in the corresponding travel direction.

  • Patent number: 6315089
    Abstract: A safety lock device including a clover mechanism mounted on a rotating shaft to be used with an unbalanced free-fall dog that precludes rotation of the rotating shaft upon rapid acceleration or excessive speed of the rotation of the shaft. The free-fall dog is pivotally mounted on a fulcrum upon which the free-fall dog may teeter in an unbalanced seesaw motion. At opposite ends of the fulcrum are a locking finger and an arm. The free-fall dog is unbalanced such that the arm contacts the clover mechanism as it rotates while the locking finger does not contact the clover mechanism at slow rotating speed. At a slow rotative speed, the arm is only slightly deflected. With great acceleration, the arm is deflected farther from the clover mechanism thereby causing the locking finger on the opposite side of the fulcrum to be pivoted into the clover mechanism.

  • Patent number: 5915909
    Abstract: The automatic vertical storage and retrieval system has an extractor for retrieving items stored and presenting the retrieved items to an operator. The extractor is vertically displaceable between and along vertical rails and is driven by an electromechanical chain drive system. The rails have equally-spaced locking slots for attaching pan brackets to form storage platforms for storage pans. The extractor includes an extractor stabilization mechanism having four locking dogs which engage with the locking slots of the rails to support the extractor and any retrieved items, thereby removing the load on the chains of the chain drive system during extraction or deposition of the storage pan(s). Thus, the extractor can be located in the optimal vertical position without the use of a precision linear encoder, and the extractor can maintain this optimal vertical position as the load is transferred to or from the extractor.

  • Patent number: 5713434
    Abstract: Disclosed is a system for engaging safeties on an elevator car. The system comprising a contact surface in a hoistway and a safety tripping lever pivotally mounted on an elevator car. Upon contact by the lever with the contact surface, the safeties engage, with the contact surface preventing the safeties from disengaging until the car comes to a stop. A feature of the system for engaging safeties on an elevator car is the ability of a portion of the safety tripping lever to retract away from the contact surface upon movement of the elevator car in a direction opposite of the car's braking direction, wherein the retraction of the lever facilitates the disengagement of the safeties.

  • Patent number: 5613576
    Abstract: A stopping apparatus for preventing drift of an elevator car stopped at a floor is actuated by a car door panel. The apparatus includes an axle rotatably mounted on the car floor, a radially extending operating arm for contact with an edge of the car door panel, at least one radially extending stop arm and a return spring for retracting the stop arm when the car door panel is closed. As the car door panel is opened, the stop arm is rotated adjacent a stop on the wall of the elevator shaft in which the car travels. If the stop is a recess formed in the shaft wall, a free end of the stop arm cooperates with the recess to prevent drift. If the stop is a floor door threshold, two stop arms are provided to prevent drift superposed above and below the threshold.
