摘要： An easily assembled and disassembled die holder assembly of the wedge locking type is provided which tightly clamps a punch die in its pocket. A die-engaging wedge of the assembly has an angular protrusion bearing on a wall of a corresponding groove in a side of the die to clamp it downwardly in the die pocket upon take-up of a threaded fastener. A locking wedge acted on by the fastener bears on the die wedge, relative angles of the latter and the protrusion causing the protrusion to hold the die rigidly. Backing off the fastener permits a resilient member to free the die from the protrusion of the die-engaging wedge.

摘要： A machine for producing points on the pilot end of a rotary fastener, the machine comprising a rotating dial for supporting an array of blank fasteners above a pair of dies. The blank fasteners are sequentially fed between the dies for pointing thereof. The dial is notched on its periphery to hold the blanks therein. The fasteners are held in coaxial alignment with the pinch point of the dies, by a notched biased centering plate, permitting accurate pointing of the fastener along the axis thereof.
摘要翻译： 一种用于在旋转紧固件的先导端上产生点的机器，该机器包括用于支撑一对模具上方的空白紧固件阵列的旋转拨盘。 坯料紧固件被顺序地供给在模具之间用于指向它们。 表盘在其外围有凹槽，以将坯料固定在其中。 紧固件通过缺口偏心的定心板与模具的夹点保持同轴对准，允许紧固件沿其轴线的精确指向。

摘要： A drilling and thread forming screw is provided with means for breaking the chips produced during the drilling process. An obstruction in the form of a truncated cylindrical element having its flat end portion substantially facing the cutting edge of the cutting surface and having its cylindrical centerline perpendicular to the cutting edge is provided on the cutting surface whereby a chip formed by the drilling process is turned back into a sharp radius, causing the chip to break.

摘要： A machine for producing points on the pilot end of a rotary fastener, the machine comprising a rotating dial for supporting an array of blank fasteners above a pair of dies. The blank fasteners are sequentially fed between the dies for pointing thereof. The dial is notched on its periphery to hold the blanks therein. The notches on the dial are acutely angled with respect to the axis of the dial and are secured thereagainst during the die pinching operation to prevent bending of the fasteners as they are pointed.
