    摘要: A cutter link for a saw chain including an elongated base having front and rear ends and upper and lower edges. Rivet holes are provided adjacent each end. A cutting portion extends upwardly from the upper edge on the rearward half of the base. A depth gauge extends from the upper edge on the forward half of the base. Said depth gauge terminates at a peak located rearward of the center of the front rivet hole and is spaced from the cutting edge of the cutting portion to provide a gullet. The depth gauge has a leading edge that is inclined rearwardly from the front of the base to the peak. The height of the combined base and cutting portion is no greater than the distance between the centers of the rivet holes plus 10 percent.

    摘要: An abrasive surface provided on a resilient substrate mounted in the path of a side sharpenable cutter. Upon engagement of the side sharpenable cutter with the abrasive surface, the substrate flexes to permit the cutter to slide over the abrasive surface. The substrate is biased toward the cutter sufficiently to achieve grinding of the metal edge of the cutter.

    摘要: Endless V-belts mounted on swathers or mowers carry side sharpenable cutters secured to the belts. One cutter includes a body having a tang projecting through a slot in the V-belt and locked thereto by a transverse roll pin with angular, oppositely extending, transverse feet portions of the body engaging the outer face of the belt, an offsetting portion extending outwardly from the belt, a shank portion transverse to the offsetting portion, and an inclined cutter plate which has a side surface which can be ground to sharpen a cutting edge thereon. The cutter plate has an angularly positioned outer edge portion which causes the cutting edge to be hooked when sharpened. In another cutter, the mounting plate extends completely through the V-belt and a roll pin and an arcuate washer secure the mounting plate to the V-belt. Another cutter includes an angular body portion, an offsetting portion and a shank portion forming a U. The shank portion carries an inclined side cutter, and a staple extends through the body, the belt and an arcuate washer to secure the cutter to the belt. An inclined side plate is secured to a shank carried by a body portion joining the shank and the foot.

    摘要: A production type machine is designed to grind end mills at a high rate while maintaining rigid standards of accuracy of dimension. Adjustments are quickly and easily made for different profiles of the ground face, the number of flutes on the mill, the size of the end mill, and so on. Operation of the apparatus is fully automatic once the grind cycle is started, after necessary adjustments are made, as only the loading and unloading operations are manually performed.

    摘要: Apparatus for use with stud welding equipment employing a stud welding gun, a power supply and a controller for initiating the welding cycle and controlling the discharge of welding energy from the power supply across the stud and workpiece which detects the occurrence of bad welds and operates to generate an alarm signal and/or discontinue further operation of the welding apparatus. A first circuit is employed across the welding power supply and senses the discharge thereof to generate a first signal indicative that a normal weld has occurred. A second circuit connected through the controller generates a second signal upon the weld command to the controller indicating an attempted weld. The first and second signals are fed into a binary counter wherein the first signal indicating a successful weld resets the counter to 0 and the second signal indicating the weld command advances the counter to a count of 1. Upon the occurrence of the first bad weld indicated by the absence of a first signal, the second signal will advance the binary counter to a binary count of 2 upon which a signal light will be turned on. Upon the second successive weld failure, the next appearing second signal indicating a second weld command will advance the binary counter to a count of 3 which functions through circuit relays to disable the welding apparatus from further operation. One bad weld followed by a normal weld will result in the first signal resetting the binary counter to 0 and permitting continued operation.
