Abstract: The disclosure describes a system for spraying an insecticide or the like, automatically and for a given period of time. The system includes a spray applicator mounted on a rotary table so as to direct a spray of insecticide all around the axis of the rotary table upon rotation of the latter. The rotary table includes a housing with a rotatable base, which is fixed at the top, a shaft extending in the housing and maintained fixed with respect to the housing. The base should be rotatable with respect to the housing. A rotatable sleeve is mounted at the bottom of the fixed shaft and is operatively connected to the rotatable base. A gear arrangement which is motor operated causes rotation of the sleeve and thereby rotates the base. An insecticide which is preferably mixed continuously is continuously fed to the spray applicator.

Abstract: A turntable wherein a base member supports rotatably a rotatable member through a shaft and a bearing. The bearing consists of a plate member positioned between the base member and the rotatable member and rollers which are rotatably held in a plurality of roller retaining bores formed in the plate member. The shaft is inserted rotatably through the plate member. The bores extend radially around the shaft.

Abstract: A rotary board for serving dishes on, comprises a generally annular base member (2), and a circular board (B) driven by a motor (8) installed in the base member (2).Ball bearing units (5, 5') are mounted between the board (B) and the base (2), which comprise a pair of coaxial ball bearing units (5, 5') the inner rings (4, 4') of which are fastened together and driven by the motor (8). The lower one (3') of the outer rings of the ball bearing units is fastened to the base member (2), while on the upper outer ring (3) rests the board (B), whereby the upper outer ring (3) and the board (B) thereon are permitted not only to rotate following the inner rings (4, 4'), but also to stay checked by hand while the inner rings are driven by the motor.

Abstract: A mechanically-driven, low-profile, portable turntable for use in cooking ovens, especially microwave ovens, for rotating food stuffs while cooking. All moving parts, except the power spring used to drive the turntable are formed from low loss plastic and the spring is contained in a microwave reflective case to preclude overheating thereof. The low profile is achieved by providing a unique drive mechanism for the turntable in which the power spring driven gear is made to partially surround and envelop the spring case. Further, the gear train cooperating with the main power spring driven gear and with a speed-controlling governor is effectively "wrapped" about the spring case in a concentric fashion with the individual gears in the gear train being vertically overlapped.

Abstract: A portable turntable apparatus for use in microwave ovens which is used as a supporting base for a container of food which is cooked within the oven and adapted to gradually rotate the same, the apparatus including a motor including metallic materials which motor is mounted in and enclosed by a metal housing and an outer enclosure comprising a cover and base of non-metallic material to prohibit electrical arcing between the motor and the oven walls. The housing is provided with smooth outer surfaces and a minimal sized aperture opening to allow a driving connection between the motor and the enclosure cover. The motor is a spring motor having an improved centrifugal governor.

Abstract: A tilting table includes a table top attached to an upper U-shaped bracket. A lower U-shaped bracket is rotatively attached by a bearing to a base. The lower U-shaped bracket includes a pair of opposed side, substantially horizontal slots and a pair of opposed side angle slots. The angle slots include a plurality of notches. Pins are slidably received in the slots, and are carried by the upper bracket for supporting the table top. The pins are selectively positioned in the notches of the angle slots, while the pins slidably move in the substantially horizontal slots for selectively inclining the table top.

Abstract: A two level turntable adapted for use in a microwave oven. The top level platform which may include a roasting rack is removably supported above the bottom level by a plurality of columns. The bottom level platform has a shaft that extends downwardly through an aperture in a microwave shielding enclosure to a motor. The motor components consisting of a coil spring and a braking mechanism are mounted in substantially the same horizontal plane to provide a relatively low vertical profile. Although the low profile is important when the bottom level platform is used by itself, it is even more important when the top level platform is mounted on top. The shielding enclosure which includes a pan shaped bottom has a downwardly bent lip from the lid to provide a low microwave field region adjacent to the connection of the pan and lid.

Abstract: A furniture swivel unit includes a base plate, a swivel plate positioned over the base plate, and a one-piece bearing located between the two plates. The base plate has an upwardly turned flange at its periphery, and the bearing, which may be molded from a low friction polymer, rests on the base plate along the flange. The swivel plate has a downwardly directed hub, the center of which is open to accommodate a retaining washer that is secured against the base plate and overlies a portion of the swivel plate, thus preventing separation of the two plates. The hub, moreover, projects into and seats against the bearing with the arrangement being such that the bearing takes both radial and thrust loading.

Abstract: A horizontal circular disc is disposed upon and is manually rotatable about the center of a square shaped horizontal top. A depressed central circular area of the disc simulates the green of a hole of a golf course and has an offset depression simulating the cup. The outer annular area is divided into a plurality of sectors of like area by radial lines. Each sector has a differently contoured top surface with roughened and smooth sections simulating the arrangement of different holes other than the green. Flat like horizontal ring shaped members (raceways) each have a plurality of spaced balls (ball bearings) therein, each ball being individually rotatable therein and having a bottom portion which extends below the member and engages the top surface of the disc when the member is place therein. Each member is dimensioned to fit into the depression and simulates a golf ball. A start position is marked on the table top. Each player in turn strikes his member with his finger to move his "ball" along the course.

Abstract: A tool box mount for a pickup truck has a frame which supports a tool box, and is itself supported above a bed of the pickup truck for swinging movement over the bed between a position wherein the tool box can be opened during use and a position where the tool box cannot be opened when the box is not in use. Pivotally mounted on a base plate secured to the bed of the pickup truck is an arm assembly which supports the frame for swinging movement, while a lock assembly affixed to the base plate selectively retains the frame in the position permitting the tool box to be opened.

Abstract: A transportable overbed table embodying a wheeled base from which there projects upwardly a vertical column on which there is vertically slidable a table-supporting carriage. An elevation screw is provided for raising and lowering the carriage. In one form of the invention such carriage movement is effected under the control of an electric motor and in another form it is effected manually under the control of a hand wheel. In the latter instance, the weight of the table is counterbalanced by means of an involute clock-type spring which is associated with the elevation screw. In both forms, the carriage preferably, but not necessarily, may support one or more drawer units which are capable of universal swinging movement in a horizontal plane.
