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.

摘要： An automatic thread cutting machine for nuts and similar mass-produced parts where the nuts or the like are taken from a magazine and moved through a feed trough into a guide where they are held secured against rotation and are then pushed by means of a pusher over a rotating thread cutter from where they are subsequently removed while the pusher is returned to its starting position. The machine is provided with an actuating cylinder which is capable of being charged with a pressure medium and which has a piston rod that is provided at its free end with a plunger serving as the pusher. A clock pulse controlled switch valve arrangement is disposed in the pressure medium line leading to the actuating cylinder, and the machine is electrically protected by a safety device which is influenced by the position of the piston rod, the safety device being rendered operative in dependence on the position of the piston rod.

摘要： The present invention relates generally to improvements in machines designed to form longitudinally extending slots in the shanks of fasteners and more particularly in fasteners having radially extending wings at the entering end portion. The machine incorporates an indexing dial with blank receiving pockets at the outer periphery thereof to transfer the blanks from a loading station to a slotting station. An orienting station intermediate the loading and slotting stations creates a rotary force on the shanks of the fasteners causing them to rotate relative to the pockets. The pockets include means to limit the rotation of the shanks therein by interengagement of one of the wings with an abutment surface formed in a recess in the pocket. The orienting station revolves the blank about its axis until the shank is properly oriented for the slotting operation.
摘要翻译： 本发明总体上涉及设计成在紧固件的柄部中形成纵向延伸的狭槽的机器的改进，更具体地，涉及在进入端部处具有径向延伸的翼的紧固件。 该机器包括在其外周边处具有空白接收袋的分度盘，以将坯料从装载站传送到开槽台。 在加载和开槽站之间的定向站在紧固件的柄上产生旋转力，导致它们相对于凹部旋转。 口袋包括通过将一个翼片与形成在口袋中的凹部中的邻接表面相互接合来限制其中的柄的旋转的装置。 定向工位围绕其轴旋转坯料，直到柄被适当地定向以用于开槽操作。

摘要： An improved method for producing a threaded, metallic, self-locking fastener having a metallic patch flame sprayed thereon. The improved method includes a heat-treating operation which densifies and smooths the outer surface of the patch while not substantially affecting the porosity or resiliency of the patch and improves the bond between the patch and the base fastener.

摘要： A machine for cutting slots in the shanks of screws includes a frame supporting a rotatable shaft with a disk attached thereto. A plurality of notches are formed in the periphery of the disk for carrying the screws and the shaft is rotated intermittently by an indexing means to move the disk along a predetermined path extending through fastener-receiving, slotting and exit stations. At the slotting station, two saws are advanced from retracted positions relative to the disk to cut slots in the shanks of two screws during a dwell period of the machine. At the fastener-receiving station, the fasteners are fed down a ramp from a feeder and are guided into the peripheral notches in the disk. An adapter fastened on the shaft above the disk includes a plurality of clamping members movable toward and away from the disk to clamp the fasteners on the disk as the fasteners are carried along the path through the slotting station. Mounted on an arm pivotally secured to the frame is a rotatable turret which is movable with the arm from an out-of-the-way position to an in-service position disposed above the adapter. Supported on the turret is a plurality of plungers adapted to engage with the clamping members on the adapter and urge the members into clamping engagement with the fasteners. The turret is mounted so as to rotate in a plane slanted relative to the plane of rotation of the adapter so that only those clamping members located in the direction of disk rotation between the fastener-receiving station and the exit station are depressed by the plungers.
摘要翻译： 用于在螺钉柄中切割槽的机器包括支撑具有附接到其上的盘的可旋转轴的框架。 在用于承载螺钉的圆盘的周边形成有多个切口，并且通过分度装置间歇地旋转轴，以沿着延伸穿过紧固件接收，开槽和出口站的预定路径移动盘。 在开槽站处，两个锯在相对于盘的缩回位置前进，在机器的停留期间切割两个螺钉的柄中的槽。 在紧固件接收站处，紧固件从进料器沿斜坡进给，并被引导到盘中的周边凹口中。 紧固在盘上方的轴上的适配器包括多个可朝向和远离盘移动的夹紧构件，当紧固件沿着穿过开槽站的路径被携带时，将紧固件夹紧在盘上。 安装在枢转地固定到框架上的臂上的是可旋转的转台，其可以随着臂从转向位置移动到布置在适配器上方的使用位置。 在转台上支撑有多个柱塞，适于与适配器上的夹紧构件接合并且促使构件与紧固件夹紧接合。 转台被安装成相对于适配器的旋转平面倾斜的平面旋转，使得位于紧固件接收站和出口站之间的盘旋转方向上的那些夹紧构件仅被柱塞压下。
