Abstract: Quick change cutting tool block clamp wherein planar mounting faces of adapter base and tool holder faces are located and retained in compressive engagement through linear interengagement of transverse semi-dovetail key surfaces under pressure established by a spaced pivoted clamping dog mechanism spanning the engagement faces. Clamping retention is entirely accomplished by means immediately adjacent the interface of the planar surfaces leaving the outer surfaces of the tool holder open and free of clamp actuating projections.

Abstract: The disclosure relates to a tool changing mechanism comprising an arm with hands at each end thereof having means to pick up both boring and turning tools. The arm is actuated by hydraulic rotary actuators and the tools are gripped by air operated fingers. A turret assembly is equipped with a boring tool holder and a turning tool holder for the acceptance of tools changed by the changing mechanism.A magazine holds replacement boring bars and turning tools until a tool change is required. An automatic tool lock-unlock mechanism is provided to lock the tools in cutting position.

Abstract: An indexable insert end mill having multiple triangular inserts spaced axially in overlapping cutting relation in isolated pockets arranged along a gradual helical angle extending axially of the end mill such pattern of axially spaced cutters being repeated at three 120.degree. circumferentially spaced positions on the periphery of the body. In a typical case the three helical rows of inserts each has five inserts equally spaced axially in overlapping relation and circumferentially in 40.degree. increments so that three effective teeth are provided at each of the five axial positions.

Abstract: An adjustable seat back hinge mechanism actuated by planetary gearing with means to provide an input/output reduction ratio within a range in the order of 30:1 to 50:1 from manual hand knob actuation or in the order of 120:1 for electric motor drive.

Abstract: Shoe manufacturing system to rough and cement lasted uppers and outsoles including subsequent operations to load shank and bottom filler, dry, spot and sole lay, scour, and ink "cement construction" shoes. The system combines non-synchronous carrousel transport with roughing and cement application stations where preprogrammed selective shoe model and size numerically controlled roughing and cementing application operations are performed.

Abstract: Air pressure actuated locking power clamp released from static loaded condition by air pressure no greater than locking pressure notwithstanding a differential smaller release pressure area due to piston rod of air cylinder. Highly pressurized needle bearings in straight track portions of the clamp which actuate links connected to a pivoted clamp arm are critical elements in providing unexpected low pressure release. Similar needle bearings in all loaded pivots of conventional toggle clamps provide 100% improvement in ratio of apply force to clamping force.

Abstract: Passenger car individual front passenger seat back actuated seat latch release means comprising pivotally connected seat and seat back bracket means, longitudinal track seat adjustment means including manual latch release means, pivoted lever means on the seat bracket means, striker means fixed on the seat back bracket means responsive to forward tilting for actuating the lever means, linkage means from the lever means for actuating said manual latch release means, the striker means including a surface for retaining the lever means in latch release mode during manual return of the seat to rearward position and seat back to upright position.

Abstract: Pin lock insert holder constructed as an essentially straight lever having longitudinally spaced hold down and fulcrum projections on opposite sides and a lever actuating recess engaged by an angularly related screw. An additional shim retention projection and snap ring accommodate loosening for insert replacement with secure retention of pin and shim against removal or dislocation. Modifications without shim retention accommodate small inserts with shorter lock pins.

Abstract: Chip control insert characterized by a chip control groove extending across polygon insert corners and along edge extending from corners with increasing width away from the cutting corner. The groove is formed with a radius extending below a narrow positive rake cutting edge land to a maximum depth tangent with the bottom of the groove.

Abstract: Circular chip control insert including a plurality of peripheral arcuate scallops having adjacent intersections terminating in points at the cutting edge of the insert providing a wedge effect in dividing and breaking chips.

Abstract: Wrap around spring detent sun visor arm for automotive vehicle capable of holding any adjusted visor use position with required torque resistance and with supplemental raised storage torque resistance, all torque resistance being provided by wrap around spring engagement with a visor arm rod having a flat for detent engagement by corresponding flat in the wrap around spring.

Abstract: The invention provides an actuating linkage assembly tolerance compensating system comprising means for establishing a final linkage pivot location at the end of assembly operations. The incomplete assembly is located with one end of a link in a piercing die press fixture oriented relative to connecting linkage to provide required final operating handle position.

Abstract: A cutting tool for improved chip forming material removal efficiency over a wide mid-range of typically used feed rates and depths of cut is disclosed in a preferred form of an indexable polygonal cutting insert. A first chip control groove of uniform width and cross section radius extends from a cutting edge at each side of the polygon and terminates inwardly from the edge in a second chip control groove having a cross section of larger radius but of lesser depth than that of the first chip control groove. The second groove has its largest width at a point substantially midway between adjacent cutting corners of the polygon and diminishes to zero width at the end of each straight cutting edge, the first groove continuing around a substantial corner radius adjoining adjacent ends of the straight portions of such grooves.

Abstract: A circular chip breaking insert having a plurality of overlapping peripheral conical depressions extending to the cutting edge including secondary conical depressions formed at the overlapping areas of the primary depressions.

Abstract: Automatic backfeed deburring system for holes drilled through non-planar hole end surfaces wherein axially resilient float in the deburring tools accommodate axial variations in the hole burr edges.

Abstract: A hinge fitting for adjustably connecting a seat and a back rest, especially for motor vehicles, in which a pair of hinge members pivotally connected to each other have means for gradually continuously adjusting the angle of the hinge members and the elements fixed thereto relative to each other and in which supplemental means are provided for quick adjustment to any approximate angular relation within the total range of seat back adjustment subject to gradual adjustment to any desired precise seat back position.

Abstract: A body assembly system for welding different stamped sheet metal vehicle bodies at successive framing and finish welding stations including means for accurately locating different underbody, side and top components in required accurate geometric relation at a framing station with programmable welding means for producing different initial retention welds at the framing station as well as finishing welds at successive "respot" welding stations as required for the different bodies. The system includes means for rapidly positioning locating tooling for body components at the framing station as required for different bodies as well as means to minimize and facilitate change of special tooling for model changeover.

Abstract: New assembly of cylinder, lightweight piston and piston rings for engines and compressors comprising in a cylinder a reduced weight piston provided with a new simpler piston rings set of a high efficiency producing a very small tension against the cylinder and lighter than the piston rings set known heretofore and wherein each of the purposes ascribed to the individual piston rings of the set is entirely attained by each piston ring of this assembly.
