摘要： A saw chain, for power saws, having cutting links alternately on the right-hand and left-hand sides, central driving links, and lateral connecting links. The individual links are pivotally interconnected by means of pins. At least some driving links are provided with a safety projection, which extends in the opposite direction to the direction of rotation. The outer edge of the safety projection is radially farther than the outer edges of the connecting links of the following driving link. As the chain rotates around the free end of the guide rail, in the direction of travel, the rearmost section of the outer edge of the safety projection describes a trajectory which is greater by predetermined amount than the trajectory described by the tip of the cutting tooth.

摘要： A saw chain, for motor chain saws, provided with depth limiters, gauges, or members, and with cutting teeth respectively arranged, in the direction of cutting movement, behind a depth limiter. Each cutting tooth projects outwardly from a base body transverse to the direction of cutting movement of the saw chain, and is set or twisted relative to the plane of the base body, with each cutting tooth having a transverse cutter which is formed by a cutting back surface and an outer surface of the twisted cutting tooth. Each depth limiter is bent laterally out of the plane of the base body of the subsequent cutting tooth, and forms a rearwardly open, acute inclined or chamfered angle with this plane. This angle may range between 3.degree. and 20.degree., and is preferably 9.degree.. The leading region of the depth limiter may be provided with a continuously and uniformly curved, downwardly extending, rounded entry portion.

摘要： The invention is directed to a saw chain for a motor-driven chain saw which includes cutting links, side connecting links, driving links and safety links. Each safety link has an upper edge defining a wave-like contour that prevents chips from accumulating during the cutting action. The cutting links and safety links of the saw chain are arranged with respect to each other so that overlap is avoided between the tail end of the rearward projection of the safety link and the forward projection of the depth limiter of the cutting tooth. This affords the advantage that cutting chips do not become jammed therebetween.

摘要： This disclosure is directed to a saw chain sharpener for a motor-driven chain saw having a guide bar assembly that includes a guide bar and a saw chain guidingly mounted thereon. The saw chain sharpener includes an elongated chain guard casing for removably receiving the guide bar assembly therein. The chain guard casing defines a cavity in the forward end thereof adjacent the nose of the guide bar. A sharpening device is mounted in the cavity for sharpening the saw chain whereby the device is contained within the casing.

摘要： A sharpening device, for the saw chain of a motor chain saw, with a holding device for a sharpening element which is arranged in the region of the reversing radius and is curved approximately concavely with respect to the center of this reversing radius. The sharpening element is seated upon an adjustment lever which is pivotable in a direction toward the saw chain. This lever cooperates with a screw device which determines the feed path of the sharpening element. An actuating handle is provided for the feeding of the sharpening element; this handle is arranged on that side of the housing of the chain saw located remote from the free reversing end of the guide bar of the saw chain. The actuating handle is preferably releasably secured in the grasping range of the front handle of the chain saw. The actuating handle is connected by a yieldable shaft with a threaded bolt associated with the feeding device, and the nut piece of the threaded bolt is seated in an extension of a support plate connected with the guide bar, that end segment of the threaded bolt which projects freely from the nut piece pressing against an adjustment lever pivotally journalled on the support plate. The adjustment lever supports the sharpening element and is spring biased, with the spring endeavoring to pivot the adjustment lever, together with the sharpening element, in a radial direction against the axis of the reversing chain gear.
