摘要： A drill sharpener is provided which has a point-splitting port which simplifies the procedure for producing a split point on a drill bit undergoing sharpening. The point-splitting port is positioned relative to a grinding wheel assembly such that, when the drill held by a chuck is advanced toward the grinding wheel, a flute of the drill at the drill tip is brought into contact with the grinding wheel. The port has alignment stops therein which mate with flats provided on the barrel of the chuck to ensure proper alignment of the chuck and drill relative to the grinding wheel. The stops also limit the extent of inward travel of the chuck and drill to a predetermined distance. A debris or grit collection tube is also provided to be inserted into an unused port of the drill sharpener, to contain and confine any debris or grit attempting to exit the sharpener through the unused port.
摘要翻译：提供了一种具有分切口的钻削刀，其简化了在经历磨削的钻头上产生分裂点的过程。分切口相对于砂轮组件定位，使得当由卡盘保持的钻头朝向研磨轮前进时，钻头的钻头的凹槽与砂轮接触。该端口在其中具有对准止动件，其与设置在卡盘的筒体上的平面配合，以确保卡盘和钻头相对于砂轮的适当对准。止动件还限制卡盘和钻头向内行进到预定距离的程度。还提供碎屑或砂粒收集管以插入钻削刀的未使用的端口中，以容纳和限制试图通过未使用的端口离开磨刀机的任何碎屑或砂粒。

摘要： A substantially universal power feed for a drilling machine has a unique clutching arrangement whereby overloads are substantially eliminated. A further safety feature comprises a shear plate which functions to stop rotation of the power feed in the event of clutch malfunction or over adjustment of the clutch release spring. The power feed is also of the type that the feeders arbor may be rotated with the clutch disengaged from the motor so that the operator has a choice of using the power feed or manually feeding the drill without the necessity of physically removing the power feed from the drilling machine.
摘要翻译：用于钻孔机的基本上通用的动力进给具有独特的离合装置，从而基本上消除了过载。进一步的安全特征包括剪切板，该剪切板用于在离合器故障或离合器释放弹簧的过度调节的情况下停止馈电的旋转。动力供给也是这样的类型：供料器心轴可以随着离合器从马达脱离而旋转，使得操作者可以选择使用动力进给或手动进给钻头，而不需要物理地从钻孔机。

摘要： A precision drill sharpener and grinding wheel assembly is provided, as is a corresponding drill chuck for use with the drill sharpener, in which the drill sharpener includes a lever and spring clip alignment subassembly for properly positioning a drill in the drill chuck, and sharpening ports for sharpening the drill and splitting the drill tip, the sharpening ports being positioned such that a single grinding wheel assembly is used to both sharpen the drill and split the tip. The drill sharpener uses a small diameter grinding wheel operated at high speed to provide cutting rates comparable to large industrial sharpeners. The drill chuck is of short length, relative to most of the drills to be sharpened, and is open at the back end, enabling the manipulation of the drill by its shank relative to the drill chuck when disposed in the alignment subassembly.

摘要： A relatively low cost twist drill sharpener apparatus employable with a rotary grinding wheel has a twist drill alignment fixture which positions the drill with respect to the drill holding chuck. The twist drill holding chuck has mounted thereto one or a pair of cam elements which cooperate with a sharpener fixture which is adjustable for height, pivotal motion and backward and forward motion relative to the rotary grinding wheel. The fixture has mounted thereto a second cam and is adapted to receive the twist drill chuck and control the grinding of the twist drill when the chuck is pressed toward the face of the grinding wheel and rotated clockwise. The fixture and the chuck are also adapted to receive a wheel dressing element.
