  • Patent number: 4185483
    Abstract: A door locking device comprising a six-sided right wedge frustum having two spaced parallel sides and parallel upper and lower bases with a first remaining side perpendicular to the upper and lower bases and a second remaining side cut at an angle with respect to the upper and lower bases. The device is securely placed between the door handle stem and the key latch to prevent the latch from rotating if an intruder attempts to place a key in the lock and rotate the tumblers, since the latch is connected directly to the tumblers.

  • Patent number: 4063319
    Abstract: A bedroll has an appearance of a cylindrical sofa cushion, by day. When unrolled, it forms bed clothing, with sheets and blankets or the equivalent. The bedroll has at least two separate layers, which are releasably secured together by fasteners. One layer is both a blanket and a shell or outer covering of attractive material that either matches or coordinates with the upholstery on a sofa or other furniture adapted to utilize a pillow similar to the rolled sleeping bag. The other layer is a washable sheeting which may be inserted into, used, and removed from the bedroll. When the two layers are secured together, their combined visible edge has a characteristic which enables the bedding to be rolled, without appearing to be rolled bedding.
