  • Patent number: 4818019
    Abstract: The seat and pedestal of a chair are joined by a knee-tilt control mechanism which includes a first support fixed to the underside of the seat adjacent the front edge thereof, and a second support fixed to the upper end of the pedestal and having a sidewardly extending tube. The first support has bearing hubs which are rotatably engaged with the tube to define a horizontal tilt axis. A restoring mechanism is disposed within the tube for exerting a restoring torque urging the seat upwardly into a horizontal position. The restoring mechanism employs compression springs within the tube on axially opposite sides of a pre-torque member which can be rotated to adjust the initial spring compression. The springs bear against actuators which rotate with the bearing hubs. The actuators have radially projecting followers for engagment with ramp-like cams formed circumferentially of the tube.

  • Patent number: 4815925
    Abstract: A circular storage container (1) for granular materials is provided with a central support column (4) for a top-loading filling device (9) and a lateral conveyor (20) for pivotal movement around the support column (4). The lateral conveyor (20) is connected to the filling device via a telescopic, vertically extendable feed pipe (12). The support column (4) is constructed either of ring plates (5) or a helically coiled band, both of which have a downward slanting, angular outer edge section (34). The granule material dropped in the vicinity of the support column (4) slides onto the ring plates (5) or along the helically coiled band according to the shape of its alluvial cone, but cannot drop into the discharge shaft. During the removal process the granular material is forced between the ring plates (5) or between the coils of the helically coiled band, from where it drops into the discharge shaft (7).

  • Patent number: 4813742
    Abstract: Disclosed herein is a footstool for use in conjunction with nursing or bottle feeding an infant. The footstool provides stable support for a mother seated while feeding or holding her baby. The footstool includes a skid resistant surface and rubber stud means for preventing the tilting and shifting of the platform while the mother is seated during the nursing of her child. The invention is especially designed so that the legs which support the inclined platform do not substantially extend outward from under the platform, allowing the entire frame to be more rigid and less susceptible to tilting which otherwise would occur when a force is applied to opposite edges of the footstool in the normal course of its use.

  • Patent number: 4805970
    Abstract: A dovetail drawer guide wherein the mortise member is attached to the outer bottom surface of a drawer and the tenon member is mounted on base frame adjacent the bottom of the drawer slideway of the case goods, further includes a pivotal drawer stop means mounted on one side of the mortise member. The stop means includes a body portion having an arcuate edge, a resilient finger member, and a leg member opposite the arcuate edge. The stop means pivots such that the leg member is out of the path of movement when the drawer is inserted in the slideway, but the leg drops by gravity to engage the forward base plate and prevent the drawer being pulled out of the slideway during normal use. The stop means is of sufficient resilience to permit overriding thereof by application of force, which force compresses both the finger and leg members, to permit removal of the drawer from the slideway.

  • Patent number: 4801176
    Abstract: A completely collapsible chaise-cot deriving an unique compact folding characteristic from a folding transverse foot-base support structure. The folding support structure gives an increased compactable collapsibility to this invention over the folding chairs and cots of prior inventions. Earlier art, although achieving a modicum of collapsibility for cots, lawn chairs and the like, was devoid of full and compact collapsibility because no provisions had been made by the inventors to fold the common transverse base and upper frame supporting structures. The long felt need, therefore, for a folding, completely collapsible transverse foot-base support structure has been fulfilled by this invention and the art form has achieved a new level of utility as a result.
