Abstract: A portable motor chain saw with a guiding rail structure which on at least a portion of its circumferential surface on which the saw chain is slidably guided has a semicircular head by which the chain is deviated while a reinforcing layer of Stellite is applied on the region of the deviating portion of the guiding rail structure, the Stellite together with the adjacent guiding rail portion being tempered.

Abstract: A guide bar for a chain saw including a main bar portion having its outer end edge abutting a mating inner end edge of a nose portion. At least a section of one of the bar portions adjacent the abutting end edges is formed by side plates supported in a spaced apart position by spacing posts. A connecting web connects the bar portions with the said one bar portion fitting between the spaced apart side plates. The web is provided with slots to accommodate the supporting posts and displaceable ear portions extend into the slots to resist but not prevent passage of the posts. Forcing the said one bar portion over the web causes the ear portions to deflect around the supporting posts which then resists but does not prevent separation of said one bar portion from the web.

Abstract: A cutting system utilizes a cutting blade-holding base that removably holds a number of long razor cutting blades in a corresponding number of longitudinal slots. A replaceable blade knife of the cutting system has a cutting blade-gripping member with a bifurcated lower region extending throughout its length and dimensioned for resiliently gripping one of the long razor blades. The blades are placed within the blade-gripping member of the cutting knife by placing the heel end portion of the bifurcated region over the razor blade at this point and then angling downward so that the remainder of the bifurcated region resiliently grips the cutting blade throughout its entire length. The cutting blade-holding base also serves to store the knife with its cutting blade by insertion of the blade into an empty slot of the base.

Abstract: The guard cover for a commodity slicing machine sharpener extends over and protects the otherwise exposed knife edge at the knife sharpening area. The guard protects the knife edge at all times regardless of whether the sharpener is in the sharpening position, storage position, or is being moved between these positions. The sharpener employs a non-rotatable honing stone which seeks proper honing relationship with the knife upon coming into contact therewith. A latch holds the sharpener when in the sharpening position and prevents it from being returned to the storage position until released. The latch release is position dependent so that the operator's hand and fingers should be in a certain predetermined position on the sharpener housing, away from the knife edge, to operate the latch release.
