Claims priority in Germany, 15 Nov 1963. Abstract: This invention relates broadly to a duplicating milling machine having a workpiece and model table adapted for movement in three coordinate directions and more particularly to such a duplicating milling machine having a spindle turret, carrying machining tools at opposite ends, mounted on the upper side of the machine standard for pivotal movement about a vertical axis. By turning the spindle turret of such a machine, one or the other of the machining tools is brought into operating position over the workpiece and model table. Claim: A duplicating milling machine comprising, a machine standard having an upper surface and a vertical axis, a table adapted for movement in three coordinate directions and adapted to hold a workpiece and model operatively connected to said machine standard, a turret portion connected to the upper surface of said machine standard for pivotal movement about the vertical axis thereof, first and second machine tool means connected at opposite ends of said turret portion in operative relation to said table, said first machine tool means including a roughing spindle, a hydraulic feeler connected adjacent said roughing spindle, hydraulic control means connected to said table and said hydraulic feeler whereby said hydraulic feeler is connected to selectively move said table through said hydraulic control means in three coordinate directions relative to said roughing spindle, said second machine tool means comprising a precision duplicating tool connected for movement in three coordinate directions relative to a fixed position of said table, guide means connected to said precision duplicating tool for moving said precision duplicating tool by hand and said turret portion being pivotal from a first position to a second position to successively dispose said first and second machine tool means in operative position above said table.

"My invention covers a novel industrial product constituted by a nut wrench incorporating a screw driver and adapted to form if required also shears for cutting thin metal sheets or wires of small diameter." Known example marked NERVOR reflect production for a French motorcycle engine manufacturer. ESPACENET also has corresponding patents from several European countries; "Clé à écrous avec tournevis combiné " (FR911097) is the original.

Assigned to Adrew Parker - Brown Valley MN

The main bar has pipe gripping teeth on one side, and a recess on the opposite side. The adjustable jaw has provision for inserting a roller cutter. It removes from the main bar and installs facing the side with the recess when used as a cutter. A known example marked, "FJELLMAN WRENCH & CUTTER PAT DEC. 12, 1894 / 4" lacks the cutter.

Claims priority in Germany, 26 Mar., 1964. Abstract: This invention relates to a copying milling machine, that is, a machine for reproducing on a work piece the configuration or shape determined by a pattern or template. An object is the provision of an improved copying milling machine in which the roughing operation on the work is performed by power feed means controlled by a tracer which engages the pattern or template, and in which the power feed parts can be quickly disconnected or made inoperative to permit the final finishing operation to be performed by hand in a most convenient and easy manner. Still another object is the provision of a machine so designed as to give improved rigidity and sturdiness as compared with prior machines, and at the same time an improved layout or arrangement of work table and pattern or template table with relation to each other, to enable the work and the template to be located in position more convenient to each other and more convenient to the location of the operator. A further object is the provision of a simple, sturdy, and compact copying milling machine so designed as to accommodate an increased size of work piece as compared with many prior machines, and one in which the milling operation is performed at a convenient location with relation to the eyes of the operator, notwithstanding that different work pieces operated upon at different times may have considerably different vertical dimensions. A still further object is the provision of a copying milling machine so designed and constructed that transmission of vibrations from the work piece and the milling spindle to the tracer is reduced to a minimum. Claim: A copying milling machine comprising an upstanding main column, an upstanding auxiliary column spaced from the main column, a work table in the space between said two columns, said table being mounted for vertical movement and also longitudinal horizontal movement, a substantially horizontal crosshead resting on and bridging the space between said column, a vertical milling spindle head supported from said crosshead and displaceable horizontally thereon in a direction transverse with respect to the direction of longitudinal movement of said work table, and a template table spaced laterally from said work table and located at least partly on the opposite side of said auxiliary column from said work table, said template table being operatively connected to said work table to move therewith during both the vertical movements and the longitudinal horizontal movements of said work table.

Assigned to Gildemeister-Devlieg System-Werkzege, GmbH - Bielefeld, Ostwestfalen-Lippe Region North Rhine-Westphalia, Germany

Abstract: A clamping device for connecting machine spindles or basic holders with tool holders or tools for machining comprises two partible damping elements (38,40;138,140) which are radially displaceable mounted in a holder (24;124) anchored in the machine spindle (10,110) or the basic holder and in the parted position engage behind an encircling clamping shoulder inside the tool holder (12;112). The clamping elements (38,40;138,140) extend crosswise to the longitudinal direction of the tool holder (12;112) and, at their lateral outer ends, have clamping surfaces (48,50,52,54;148,150,152,154) disposed such that all four clamping surfaces of the two clamping elements (38,40;138,140) are each distributed over the periphery of the clamping shoulder at angular distances of approximately 90.degree.
