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.

Our invention relates to that class of centrifugal governors in which the balls or weights rotate with and upon the main or driving shaft of the engine, and operate, by variations of angular velocity, to vary the position of an eccentric thereon relatively to the crank, examples of which class will be found in the Letters Patent of Jacob D. Custer, No. 1,179, dated June 21, 1839, and in Letters Patent No. 162,715, granted to Joseph' W. Thompson and the Buckeye Engine Company, (as his assignee,) under date of April 27, 1875. Abstract: The improvements herein claimed are intended for application to the governor shown in the patent last above stated and consist, first, in combining, with the pivoted weight-arms, and the links by which they are connected to the movable eccentric, ball-and-socket joints and, second, in combining, with the pivoted weight-arms, stop-pins working in slots in the supporting-case between and equidistant from the pins, which form the pivots of the weight-arms on the one side, and from similar pins on the other side, which latter, when the motion of rotation is in the direction shown by the arrows, form the points of attachment for the springs, said stop-pins abutting at either extremity of the traverse of the arms against spring-cushions secured in the ends of said slots. Claim: The combination, with a steam-engine governor adapted to be mounted upon the driving-shaft, of a loose eccentric fitting upon the shaft and connected to the weight-arms of the governor by links, united with said arms by ball-and-socket joints.
