Abstract: An adjustable tool holder for carrying a tool, such as a paint brush, on a handle, such as an extension handle. The invention broadly includes a yoke assembly for mounting the holder on the handle and a carrier assembly for carrying the tool. The yoke assembly has a generally U-shaped configuration, with yoke arms extending upward from a handle mount. The carrier assembly includes a link assembly for mounting the carrier assembly on the yoke for angular movement in discrete preselected steps about an axis passing through the yoke, operable by imposing a moment force on the link assembly. Link arms extend between and in sliding contact with the inner surfaces of the yoke arms, with axle plugs joining adjacent yoke and link arms for rotational movement. A series of detent recesses and projections, respectively formed in adjacent yoke and link arms, permits rotational movement in a series of discrete steps of selected angular distance, without requiring the loosening of any screws or wing nuts.

The tool includes a base element, generally T-shaped in outline, including a handle and a blade receiver with a fixed jaw face oriented toward the central plane of the tool, and a lever aperture extending through the blade receiver adjacent to the handle. A locking aperture in formed in the handle remote from the blade receiver means, with a locking rail disposed therein, oriented generally parallel to the blade receiver. A blade clamp is pivotally attached to the base element and includes a movable jaw face and a perpendicular blade clamping lever, divided into three portions in a zig-zag pattern, carrying a latch, adapted to engage the locking rail at its extremity, and an unlocking point at its distal end.

Abstract: An improved system (30) provides fast contact in a conversational video system by use of a screen pointer (200) in connection with a windowed display of a financial data page and a unique subscriber identification code with or without an interest message code. When an interest message code is provided, the prestored interest message is expanded and inserted in the command line. If a double click is employed with the mouse 200 screen pointer, contact is automatically initiated with the called party and the interest message transmitted. However, if only a single click is detected, the interest message is inserted in the command line without being automatically transmitted. The subscriber may then double click his mouse screen pointer (200) at the location of the code in the display (76) or may press the TRANSMIT key on the keyboard (72) to send the interest message to the called party. The system (30) may also use CONTACT LISTS to initiate conversational contacts.
