  • Patent number: 4306338
    Abstract: A slide fastener stringer includes a stringer tape and a series of fastener elements sewn to the stringer tape on one of the opposite surfaces thereof along its one longitudinal edge by means of double locked stitches composed of at least one needle thread and a looper thread. The needle thread includes a thermoplastic monofilament yarn, and the looper thread includes a spun or multifilament yarn. The stitching has been done from the tape side of the slide fastener stringer. Loops of the looper thread project hardly from the topmost surface of the needle thread loops so that a slider is not likely to wear it out. Each of the needle thread has a constricted portion which serves to keep the looper thread loops from becoming loose. After stitching of the fastener elements to the tape, the thermoplastic monofilamentary needle thread has been heatset to suitably shrink and then become dimensionally stable.

  • Patent number: 4305167
    Abstract: A bed making device with a structural support base adapted to receive springs and mattress with two horizontal guide members attached at either end of the base on each side. A carrier arm is slideably positioned on each pair of guide members and contains a retractable detent pin at the top. The pin attaches to a mating opening in the bed linens and the linens are attached to the pins at the foot of the bed. A reversible electric motor with a two position foot switch, limit switch and gear driven belt drive is attached to the arms electromechanically, thereby transmitting linear direction to the mechanism. The carrier arms are horizontally propelled simultaneously forward pulling the bed linens in place. When the linens are so positioned the detent pin is retracted and the arms continue forward to a position near the head of the bed where they stop automatically.

  • Patent number: 4304018
    Abstract: A bed covering includes a top covering adapted to overlie the top surface of a mattress, a side covering adapted to be fitted to the mattress and to surround the head end, foot end and sides thereof, and a foldable side panel interconnecting the top covering and side covering along the foot end and at least one side of the mattress so that the mattress, side panel and top covering define somewhat of a sleeping bag type enclosure for receiving a person. A first zipper along the edge of the top covering and top edge of the side covering enable the bed to be made by simply closing the first zipper to thereby foldably collapse and enclose the side panel between the top covering and mattress. A second zipper may be provided between the side panel and side covering to facilitate entry onto the mattress below the bed covering.

  • Patent number: 4304030
    Abstract: A slide fastener stringer has a woven stringer tape including a web and a tube extending along one longitudinal edge of the web, and a row of coiled coupling elements woven into the tube. The coupling elements comprise a plurality of coupling heads and a plurality of connecting portions each interconnecting two adjacent coupling heads and disposed in the tube, there being a core extending longitudinally through the coupling elements. A pair of stuffer cords extend longitudinally through the tube and are held against the connecting portions of the coupling elements. Two of the warp threads in the tube are disposed on the respective stuffer cords, serving as corners for guiding a slide fastener slider therealong. Other two of the warp threads in the tube are of less diameter than the corner warp threads at portions of the stuffer cords which are remote from the connecting portions of the coupling elements.

  • Patent number: 4303162
    Abstract: A spring-driven track unit for merchandising soft drink bottles has a sliding sheet metal pusher having a forwardly extending foot and a sloping back extending upwardly and forwardly from the rear edge of the foot. A self-coiling polyester sheet extends from a coil retained at the front of the track, along the supporting surface of the track and underneath the pusher foot. The self-coiling sheet is secured to the back of the pusher and provides a bearing surface for a driving spring which is in the form of a narrow, self-coiling strip. The driving spring is secured to the track near the front end and extends rearwardly in a recess to a coil located behind the sloping back of the pusher. The force of the pusher on the bottles is adjustable by bending the sloping back upwardly or downwardly. The pusher is prevented from sliding off the track by tabs bent downwardly from inwardly extending flanges below and integral with the track.

  • Patent number: 4301560
    Abstract: An improved adjustable waterbed mattress with hydrostatic wave absorption comprising a water-inflatable bag-like enclosure containing therein a non-woven or very loosely woven expanded fiber product, unbonded or fixed with a binder to the same or another fiber product, which resists decomposition in water. When a user sits or lies on a conventional waterbed there is a tendency to sink or bottom out especially on the edge and an undesirable wave front is created in the waterbed mattress. The provision of the subject expanded fiber product in the waterbed mattress of the present invention substantially mitigates and dissipates this wave front and allows the bed to be easily packaged, filled, heated, drained and stored.

  • Patent number: 4301559
    Abstract: A sofa bed mechanism consisting of three sections, namely, a rear section, an intermediate section, and a front section, that are foldable between collapsed sofa positions in which the sections are in substantially horizontal vertically stacked positions and bed positions in which the sections extend in substantially horizontal alignment. A frame supports the sections, the frame being of minimum width by which is meant the frame is of a shallow dimension in a direction front to rear of the sofa. The sections are stacked on top of the frame in their sofa positions so that the frame and the sections present a compact substantially rectangular profile when viewed from the end of the frame, thereby allowing substantial flexibility in the design of the sofa in which the mechanism is mounted. The end sections are connected by hinge assemblies located entirely on the sides of the assemblies to avoid the necessity for any cross tubes that might interfere with sleeper comfort in the bed position of the mechanism.

  • Patent number: 4300793
    Abstract: A heavy duty security lock is shown that is easy to install to an existing movable closure for holding the closure in a closed position relative to a fixed enclosure. An important feature is the ease of mounting this security lock between the door and the door jamb. In order to prepare the door for receiving this lock, it should have a through hole near the vertical free edge of the door similar to the through hole for receiving a standard cylinder lock on the order of about two and one-eighth inches in diameter. The present invention incorporates a base plate having a perpendicular locking tongue fitted with a shortened collar that is mounted within the through hole in the door. An adjustable locking means engages the collar and fastens the base plate to the door. The locking tongue has a transverse hole.

  • Patent number: 4300374
    Abstract: A key retaining cylinder for a lock operative on standard keys is disclosed. The cylinder of the lock includes an idler ring driven in rotation, with lost motion, by the lock plug. The idler ring is cooperatively disposed with respect to one of the pins so as to restrict the motion thereof when that lock has been used to lock the lock set and to not restrict the movement thereof when that lock has been used to unlock the lock set. Restricted movement of the pin together with the contrapment of the pin within the combinational notch of the key prevents removal of the key. Further features and embodiments are disclosed including provisions for symmetrical operation thereof for left-handed and right-handed doors.

  • Patent number: 4300269
    Abstract: A device for locking one or more cords or other flexible elements against longitudinal movement, and including two members interconnected for relative pivotal movement between locking and released positions, with one of the members having a portion which is slightly laterally deflectible upon assembly of the device to permit movement of a pivot lug into a pivot recess to form the pivotal connection between the members, and with the other member having an interlocking projection which in the locking relative position of the members blocks lateral movement of the deflectible portion of the first member to prevent disassembly of the parts in that locking position.
