Abstract: When moving the guide bar on a chain saw in order to adjust the chain tension, the following procedure is applied. Through the guide bar runs a shaft (19) having a slot for a screw driver as well as a shape of a cog-wheel (18) on the inside of the guide bar. The hole in the guide bar is the ordinary hole for a tension pin. The cover (11) above the clutch also keeps the guide bar in place and has an oval opening (23) providing accessibility to the above shaft in all its positions. Inside the guide bar, in the saw body, there is a suitable oblong cavity (16) to make room for the cog-wheel part of the shaft. That cavity has on its lower edge the form of a straight toothed section (17) adapted to the cog-wheel part.

Abstract: A blade assembly for electric hair clippers includes a stationary blade having a plurality of teeth arranged in a row, and a reciprocating blade having a plurality of teeth which complement the stationary blade teeth. A cam eccentric which is turned by a shaft attached to a motor moves the reciprocating blade in a back-and-forth motion through a set operating stroke, determined by the lateral distance the cam moves during its rotation. A guide bar maintains the reciprocating blade in a blade guide parallel to the stationary blade throughout the operating stroke, but not through the maximum stroke the blade can travel when the head assembly is removed from the handle for cleaning or other servicing. Anti-lock ribs or an anti-lock bar are provided on the blade guides to engage the guide bar throughout the maximum stroke distance, thereby maintaining the reciprocating blade parallel to the stationary blade throughout the maximum stroke.

The handle functions as both a grasping means and a base means. The handle comprises a vertical cylinder for grasping and a flat bottom surface adapted to rest upon a flat surface such as a table. This flat bottom surface enables the eating utensil to remain upright on the table so that the eating utensil may be easily grasped and picked up. In addition, the utensil head may be modified to increase the surface area available for the food and to increase stability of the food on the eating utensil. The new and improved eating utensil is capable of being used with individuals with a variety of disabilities, particularly those individuals with limited wrist movement.

Abstract: A chain saw guide bar assembly includes opposing outer laminates in spaced relation as defined by a wire structure lying generally about the periphery of the laminates, but spaced inwardly of the edge boundary thereof whereby a saw chain groove formation results as defined by an exposed or outward facing portion of the wire structure and exposed portions of the inner surfaces of the outer laminates. The wire structure advantageously provides, in combination with the outer laminates, a containment cavity for a foam-adhesive core laminate which expands upon curing to fill the cavity and to adhere to the inner surfaces of the outer laminates. A very rigid yet lightweight chain saw bar results with less production complexity and cost relative to that of other core laminate chain saw bars.
