Abstract: A compound counterbalance system for window sashes and the like, comprising: a biasing mechanism for easing operation of a window sash and the like, the biasing mechanism being movable at an inherently variable of force; a first biasing force transmission, connected intermediately of the window sash and the like and the biasing mechanism, for increasing the effective range of movement of the biasing mechanism; and, a second biasing force transmission connected intermediately of the first biasing force transmission and the biasing mechanism, the second biasing force transmission having a variable rate of operation predetermined to automatically compensate for the variability of the biasing mechanism, to provide substantial constancy of the biasing force. The biasing mechanism preferably comprises a linearly extensible and contractible spring. In one embodiment, both the first and second biasing force transmissions comprise pulley and cable systems.

Abstract: A panel and frame weatherseal combination is disclosed for sealing the marginal edges of a panel closing an opening defined by a frame, with particular utility for sealing the corner areas thereof. The panel has an exterior surface facing the outdoors. The weatherseal comprises a longitudinally extending backing strip of a generally uniform cross-section throughout its length, to which a plurality of spaced-apart longitudinally extending flexible barrier fins are affixed longitudinally along and transversly extend from the backing strip. The innermost barrier fin extends past the marginal edges of the exterior surface. Any outdoor air movement or the like impinging on the exterior surface presses the innermost barrier fin into sealing engagement with the marginal edges of the exterior surface. At the corners of the panel and frame, the barrier fins are interdigitated to provide an excellent corner seal.

The J-shaped frame member comprises a flat intermediate plate member, a head on one side of the plate members having portions thereof laterally extending outwardly in opposite directions from the plate member, and a foot member on the opposite side of the plate member laterally extending therefrom. The frame member further has a pair of opposed elongate lips on the plate member, one of the lips laterally extending from one side of the plate member and the other of the lips laterally extending from the opposite side of the plate member.

Abstract: A method and apparatus is disclosed for making improved tufted buffing pads of varied density across the face surface thereof. The apparatus comprises a tufting machine for placing pile in a spiral or circular pattern on a backing pad to form the buffing pad. The backing pad is held by a rotatable and laterally-movable pad holder which is coupled to a programmable controller. An improved buffing pad of varying density is achieved by coupling a programmable computer to the programmable controller for varying the length of intermittent steps that the pad holder is laterally moved relating to the tufting machine. By proper programming, pile applied to the backing pad is maximized in a selected high-wear area of the buffing pad, and minimized in a selected low-wear area of the buffing pad.

Abstract: An elongate weatherseal is disclosed for installation in a right angled recess in a door frame or the like. The weatherseal comprises, in its manufactured state, a flat, rigid, plastic base member having side edge portions and a central portion. A rigid attachment member depends from one side of the base member. A pair of legs formed from a soft resilient material are secured to the side edge portions of the base member, and extend outwardly toward one-another from the opposite side of the base member. The weatherseal further has a hinge notch on one side of the base member substantially at the junction of the base member and attachment member to facilitate bending the weatherseal 90.degree. during installation thereof into the door recess.

Abstract: An elongate weatherseal for use in a motor vehicle body structure having an upper window frame, and a door having a windowpane movable between raised and lowered positions relative to the window frame. The weatherseal comprises an elongate hollow resiliently deformable body member having a V-shaped window retaining member with first and second arms. The first arm is secured to a first portion of the body member, and the second arm extends into the hollow part of the body member. When the windowpane is moved to its raised position, the upper end thereof engages a second portion of the body member and moves it inwardly into engagement with the closely spaced second arm. Inward movement of the second arm by the windowpane causes the first arm to move inwardly. Inward movement of the first arm flexes the first portion of the body member into engagement with the outer surface of the upper end of the windowpane for retaining the windowpane into sealing engagement with the weatherseal.

Abstract: A channel-shaped single-wire carrier is coated with elastomeric material to form an edge protector trim strip of substantially U-shaped cross section. The single-wire carrier is formed from a continuous metallic serpentine wire having oppositely facing looped edge portions or bights joined by lengths of wire extending transversely and spaced from one another longitudinally of the carrier. Some of the bights are located along one edge line, others along the opposite edge line, and still others along a line parallel to and interposed between the edge lines. The bights cyclically recur in a predetermined order to provide a wire carrier having a longitudinally extending reinforced portion. A plurality of strands of material extending longitudinally of the carrier are interwoven with the lengths of wire to maintain the spaced relation.

Abstract: In a window sash of the kind which in use is vertically movable within a stationary frame, an assembly for holding the sash at an elevated, partially open position in the frame comprising: at least one stop element carried within a downwardly open recess in said sash and mounted in said recess for free sliding movement in the plane of the sash between a retracted position in the recess and an extended position in which a portion of the stop element protrudes out of said recess; and a manually operable latch carried by said sash selectively operable to hold said stop element in its extended position and to release said element for free sliding movement within said recess, whereby raising of said sash in its frame allows said stop element to move to its extended position and whereby said element may then be latched in its extended position.

Abstract: An improved channel-shaped wire carrier is coated with elastomeric material to form an edge protector trim strip of substantially U-shaped transverse cross section. The wire carrier is formed from a continuous metallic wire looped to form looped ends adjacent the edges of the carrier joined by transversely extending lengths of wire spaced from one another longitudinally of the carrier. A plurality of strands of material extend longitudinally of the carrier and are interwoven with the wires to maintain the spaced relation thereof. At least two of the strands are located along the looped ends at each edge of the carrier and are forced together by the curvature of the looped ends prior to the coating operation to form at least a pair of grouped edge strands. The remaining strands are located only along intermediate portions of the base and side flanges of the channel-shaped wire carrier.
