Abstract: A mechanism, suitable for mounting in a sewing machine cabinet, is provided for supporting a sewing machine in a first position in which the work supporting surface of the sewing machine is coplanar with the cabinet top and a second position in which the bed of the sewing machine is elevated above the cabinet top allowing for free arm sewing. The mechanism includes a mounting cradle spaced in parallel relation above a base, which is pivotally mounted to the cabinet, and crossing brackets interconnecting the cradle and the base. A lever actuated linkage raises and lowers the cradle between the two sewing machine positions.

Abstract: A serving cart, including a wheel mounted housing, is provided with a serving top having a series of openings therethrough for the selective projection of bottles and the like carried by an internal shelf. The shelf is power driven so as to selectively raise and lower relative to the top. A pair of leaves are hinged to opposite sides of the top and selectively overlie the top or project laterally outward therefrom.
Abstract: The present invention relates to a device for moving upwardly and downwardly a heavy device like a sewing machine body by make use of a constantly loading spring, more particularly, an ascent and descent means of a free-arm sewing machine, comprising an ascent and descent guide means like a guide rail in a cabinet of a free-arm sewing machine, a guide bar slidable inside the ascent and descent guide means, said guide bar being installed under a rectangular base plate for fixing the sewing machine body, a constantly loading spring of balanced or over-balanced load to be provided between the cabinet and the base plate, and a latch means which is provided at the ascent and descent guide means in order to fix the sewing machine body at a preferred position.
Abstract: A filing cabinet includes a supporting frame assembly which is attachable to a supporting structure, such as a wall, a document support assembly attached to the supporting frame assembly, a plurality of document clip members having hooks mounted on the document support assembly for vertically suspending therefrom documents to be stored, and a movable cover assembly mounted on the supporting frame assembly and movable between a closed position enclosing documents suspended from the document clip members and an open position spaced from such documents.
Abstract: A locking mechanism for a cabinet enclosure is comprised of a locking member in reciprocable, captured engagement with a first of a plurality of side walls defining the enclosure, a latch support disposed within the enclosure, and a latching member borne upon that support for operative engagement with the locking member. Also provided is a panel support member in pivotal, depending engagement from the latch support for supporting a side wall of the enclosure when the same is raised to an access position.
Abstract: A storage case for holding spools of thread and bobbins is so designed as to be mountable on an outer vertical wall of practically any existing sewing machine cabinet. The case includes an outer frame which is mounted on an exterior wall of the sewing machine cabinet and a vertically slidable drawer unit therein. Partitions within the drawer unit include upright spindles for holding the thread and bobbins in place. The drawer unit further includes a resiliently biased, frictional connecting means between the frame and drawer unit for holding the drawer in any desired raised, open position whereby the thread or bobbins may be removed for use.
Abstract: A mechanism for automatically elevating or lowering a pulpit or lectern. A pulpit or lectern (hereinafter collectively "pulpit") is secured to the top of a rectangular box-like carriage. The carriage is guided during vertical movement along a plurality of guide rails by a plurality of pillow blocks secured to the carriage and engaging the rails. The rails are located within a pit which holds the pulpit and carriage when fully lowered. A vertical drive screw aligned with the center of the carriage and parallel with the guide rails engages a drive nut secured to the carriage. A reversible electric motor is adapted to drive the drive screw which moves the carriage between positions. The guide rails are adapted to guide the carriage and pulpit between a "down" position within the pit and an "elevated" position above the pit for use. Appropriate switches are provided to permit efficient operation of the system.
Abstract: A ceiling mounted storage box which is reciprocable on vertical guide rails mounted on opposed walls of an enclosure. The box is raised and lowered by a rope threaded through an eyebolt attached to the ceiling. The eyebolt projects into the interior of the box. The end of the rope threaded through the eyebolt is fixed to the interior floor of the box, so by lowering or raising the rope through the eyebolt, the box is lowered or raised on the vertical guide rails.
Abstract: A vertical sliding closure panel assembly for an appliance such as a refrigerator cabinet for closing a service area located on a food compartment door. The sliding closure panel has its edges formed with inwardly offset integral flanges defining vertical channels for reception of return flanges formed on the frame portions of the assembly providing passageways for the channels. The sliding panel has resilient clip members positioned on its side flanges operative to impart positioning stability so that the panel can be retained at any location between its fully open and fully closed position.

Abstract: Apparatus is disclosed for dispensing and serving hot and cold foods comprising a cabinet having either one or a plurality of compartments within the cabinet for holding food, heat exchange means mounted in the compartments of the cabinet and an elevator in each compartment for raising or lowering food out of or into each compartment.
Abstract: A bar table, the top of which is shaped as a polygon so as to fit an individual seat adjacent each side of the table. A storage section for bottles and glasses is mounted to the structure of the table top, which table top structure is slidably mounted in the table pedestal so that the table top structure may be elevated to expose the storage shelves or alternately, the table top structure may be slid inside the pedestal to enclose the shelf structure.
Abstract: A power-operated vertically adjustable shelf is supported by shelf arms in cantilevered fashion at the rear of an appliance cabinet by a gear and roller on each shelf arm, with each gear and roller vertically offset engaging a vertically extending toothed rack and a roller track. Electric drive means, carried by the cabinet, powers a vertically extending drive shaft of which the torque is transmitted to the shelf operating gear through a normally disengaged clutch which is engaged by user operating means adjacent the front of each shelf whereby powered vertical movement of the shelves is achieved. A dual position selector shelf switch is operable upon opening the door to permit the user to select up or down power shelf movement with the shelf switch being neutralized upon closing of the cabinet door.
Abstract: Apparatus for moving an article such as a kitchen wall cabinet or the like, mounted for sliding movement on the kitchen wall, between a normal elevated position at which the cabinet top is spaced from the kitchen ceiling and at which upper spaces in the cabinet are relatively inaccessible and a lowered position at which such spaces are accessible, in which a drive mechanism disposed between the top of the cabinet and the kitchen ceiling includes a lemniscate gear which is carried by a floating shaft and which is held in operative relationship with a drive gear carried by a motor driven shaft rotatably mounted at a fixed location by means of a plurality of idler gears interconnected each with the other and with the drive gear by means of a parallel motion linkage, two arms of which provide the input to a lazy tongs type linkage, the output arms of which are connected to the cabinet adjacent to its upper end, so that a single revolution of the input shaft moves the cabinet from its elevated position to its lowe
