  • Process for encapsulating glass fiber insulation
    Patent number: 5685938
    Abstract: Encapsulated glass fiber insulation is made by forming a covering material over the top surface of a mineral fiber core, with the formed covering material extending adjacent the side surfaces. The covering material is greater in width than the sum of the widths of the top and two side surfaces, so that the edges of the formed covering material extend beyond the mineral fiber core. A vacuum is applied below the mineral fiber core to draw the formed covering material extending beyond the side surfaces under the core.

  • Window latching mechanism
    Patent number: 5662363
    Abstract: Windows are provided including a latch member which is pivotably mounted to one of the support structures of the window. The latch member includes a body portion including first and second transverse ends. At one end is located a projecting portion which extends laterally from the body portion. This projecting portion includes a first contact surface which slides against a descending panel of the window when the panel is lowered into a closed position. This sliding action rotates the latch member away from the path of the lowering panel. Upon closing the panel, the latch member is then rotated substantially by gravitational force to a latching position along the panel to secure it in a closed position. This invention is particularly adapted to bug and security screens.

  • Composite shingle having shading zones in different planes
    Patent number: 5660014
    Abstract: A laminated shingle is provided, having lighter and darker granule portions visible from the front, at different planes; the front-most or anterior plane generally having granules of lighter shading and the more rearward or posterior plane generally having darker granules. The darker granules in the more posterior plane are visible from the front of the shingle to provide visually sharp, precise delineation between zones of lighter and darker shading. The shingles may be of multi-layer construction with suitable adhesives securing the layers together. The darker granules may be visible from beneath the lower edge(s) of the anterior shingle, to provide a shadow line effect. Alternatively, or in addition thereto, the darker shingle zones from the more posterior plane may be visible through tab-separating slots of the lighter shaded anterior shingle portion.

  • Method of making hip or ridge shingle
    Patent number: 5575876
    Abstract: A shingle is provided that is especially adapted for application to hips or ridges of a roof. In a preferred embodiment, the shingle is a laminated multi-layer shingle, bent or curled into a preformed shape that is reasonably close to the shape that it will have in the installed condition. The shingle layers are connected together in more than one zone, or in one large zone after sliding relative to one another as the shingle is bent or curled. Preferably, such connection is by means of an adhesive.

  • Window vent stop
    Patent number: 5575116
    Abstract: Window vent stop devices are provided by this invention which include housing and stop block portions in which the stop block is pivotally mounted within the housing to provide a first position for permitting at least one of the sashes of a window to slide freely by the other, and a second position which causes the stop block to impinge against the other sashes to limit the sliding movement of the sashes. The stop block includes an integral spring arm to assist it in moving from the first and second positions.

  • Reinforced exterior siding
    Patent number: 5526627
    Abstract: Exterior finishing panels are provided which contain an elongated, thermoplastic sheet which is supported by a rigid support member disposed along a portion of the length of the sheet. The rigid support member has a flexural modulus which is significantly greater than the modulus of the thermoplastic sheet, so as to support the panel during handling and installation. The panels of this invention will be more kink-resistant, and will ride uneven walls better to present a flatter-looking finished wall surface. These panels are also capable of being worked with ordinary hand tools, such as a standard wood saw made of steel or carbide.

  • Towable nonconductive pipe adapter for a sprinkler having laterally extending surfaces
    Patent number: 5511826
    Abstract: Mechanically locking sprinkler fittings are provided by this invention for making a fluid connection between irrigation pipes. The sprinkler fittings contain a tubular fitting member having first and second open ends for mating with a pair of irrigation pipes. The tubular fitting member contains a laterally facing orifice for receiving a sprinkler riser and an annular recess located along its surface which corresponds with a mating annular recess on at least a first of the irrigation pipes to form an annular cavity. The fitting also includes a flexible spline inserted into the annular cavity to form a mechanical lock between the first pipe and the tubular fitting member. The sprinkler fittings of this invention are convenient to use, and can be made of lightweight polymeric materials.

  • Mechanical joint pipe adapter with inserted flexible spline
    Patent number: 5509699
    Abstract: Mechanical pipe adapters are provided by this invention which include a gland for fitting around the circumference of a first pipe. The gland includes an annular recess located along its inner diameter and an aperture through a side wall of the gland for communicating with the annular recess. The adapter further includes a flexible spline inserted into the annular recess through the side aperture. The flexible spline forms a mechanical lock between the first pipe and the gland. After mounting the gland to a pipe, such as a PVC pipe, the gland can be thereafter mounted to a flanged end of a pipe, e.g., a cast iron fitting.
