  • Patent number: 3948204
    Abstract: An apparatus for pivotally mounting an outboard fishing motor, such as a shaft-mounted submersible electric motor, on the bow of a fishing boat or the like for pivotal movement between an operative position wherein the motor is held in the water and a non-operative raised position. The apparatus comprises an elongated mounting frame, a slide block carried by the mounting frame, and a bracket pivotally carried by the slide block for supporting the shaft of the motor. A power control system is provided which includes a reversible electric motor and cable arrangement for selectively translating the slide block in either direction, and a pivoting and lifting arrangement is included which serves to lift the outboard motor into its raised position overlying the mounting frame.

  • Patent number: 3942926
    Abstract: An apparatus for fabricating foam pads having a generally flat inner surface with a depending peripheral edge, the flat inner surface including a dense outer crust. A spring assembly is adapted to be disposed so that the terminal face portions thereof contact the outer crust and with the depending edge of the pad confiningly receiving the spring assembly to prevent lateral displacement therebetween. The apparatus includes an open top mold, and a mold insert which is adapted to be floatingly positioned on the upper surface of the foaming material to level the same while permitting the formation of a dense outer crust thereon. The depending foam edge may then be formed by adding additional foamable material along the periphery of the pad between the border of the mold and mold insert, or by suitably attaching a preformed foam strip therealong.

  • Patent number: 3941639
    Abstract: Corrugated plastic tubes simultaneously feeding from a plurality of sources are doffed, stacked in nesting relation and formed into bundles of a predetermined number of tubes in accordance with the present invention. The corrugated plastic tubes are produced in continuous length in separate production lines, cut to predetermined lengths, and fed along predetermined paths to respective doffing stations where the tubes are doffed into a common hopper positioned adjacent the doffing stations. Upon a predetermined number of the tubes being doffed into the hopper and accumulated in stacked and nested relation, the tubes are advanced to a bundling station where strapping machines secure pliable strapping elements around the stacked and nested tubes to form the same into compact bundles. The bundles are then removed from the bundling station ready for shipment or storage.

  • Patent number: 3938922
    Abstract: Cast panels for building assembly and erection are formed and cured through the use of an apparatus which particularly facilitates high rates of production of such panels and thereby facilitates more economical building construction practices. Fluid materials being cast into panels are received within forms which comprise a cured concrete bed defining a horizontal planar surface maintained at an elevated temperature. Following curing of the fluid materials cast into the forms, stripping of the panels from the form is facilitated by vertically movable side forming members and by bulkheads separating the cured materials into predetermined panel lengths.

  • Patent number: 3935803
    Abstract: A portable apparatus for directing a filtered stream of air downwardly over a predetermined area such as a hospital bed or the like. The apparatus includes a cantilevered plenum chamber adapted to be positioned horizontally over the bed, the plenum chamber comprising two segments hingedly interconnected so that the forward segment thereof may be dropped downwardly to facilitate movement and storage. The bottom wall of the plenum chamber comprises an openwork screen bounded by a peripheral slot, and a layer of filtering media overlies the screen such that a first portion of the air entering the plenum chamber is directed downwardly through the filtering media and screen at a relatively low velocity and in a substantially laminar flow pattern, and a second portion of the air is directed through the open slot to define a peripheral air curtain of relatively high velocity. The air curtain thereby serves to prevent the incursion of unfiltered air from the surrounding environment.
