Abstract: An apparatus having a foot, a reciprocating saw and a housing. Between the foot and the housing there are means for releasable mounting the foot on the housing, characterized in that the releasable mounting means have a first coupling member connected to the foot and, co-acting therewith, a second coupling member connected to the housing. The coupling members can be carried from a disconnected to a connected position by a relative displacement between the foot and housing.

Abstract: A releasable, double locking knife including a body having a cavity and a pair of opposed arms, each having a free end extending into the cavity, and a blade connected to the body for rotation between the closed position wherein the blade is disposed substantially within the cavity and an open position wherein the blade is disposed substantially outside the cavity. The opposed arms engage side surfaces of the blade when the blade is in the closed position to resist movement of the blade out of the closed position. The arms further engage stop surfaces on the blade when the blade is in the open position, thereby locking the blade in the open position. The blade further includes a release mechanism for moving the arms out of locking engagement with the blade to permit movement of the blade out of the open position.

The spacers are arranged at preselected locations on an outer surface of the drill bit structure. A hardfacing material is then applied to the drill bit structure, and the spacers are removed. Holes are machined in the drill bit structure at the preselected locations, and drilling inserts are positioned in each hole. A method of forming a drill bit structure, the method including applying a hardfacing material to selected surfaces of the drill bit structure. The hardfacing material includes a perforated carbide infiltrated material and a perforated powder infiltrated material. The perforations in the powder infiltrated material correspond to the perforations in the carbide infiltrated material.

The sharpener is retained by a U-shaped spring member which engages against a retention flange associated with the sharpener.

Abstract: A cam lever arrangement is provided which permits the loosening and tightening of the chain on the chain saw blade tool with a simple lever motion. The lever arrangement is connected to the motor housing cover door. Opening the door automatically loosens the chain. Closing the door automatically tightens the chain. Precision adjustments to tension are easily made in the cam lever arrangement by hand manipulation of a turnbuckle which is free from pressure when the lever is in the release position.

Abstract: A combination measuring, marking and cutting tool comprising a housing, a measuring tape extendable from the housing, a ferrule attached to the free end of the measuring tape, an aperture formed in the ferrule, and a T-shaped pivot tab secured to the housing in proximity to the measuring tape.

Abstract: A cutting tip having a three-layer laminated structure is provided. The tip is made from a disc-shaped three-layer laminate wherein a second layer consisting of a hard sintered compact of CBN or diamond is sandwiched by a first layer and a third layer consisting of a tool material such as cemented carbide. Prismatic blanks of rectangular cross-section are cut out by cutting the three-layer laminate in strips. Semi-completed tips of a desired shape are obtained by cutting up the prismatic blanks. Desired cutting edges are formed on the semi-completed tips to produce completed tips. Because prismatic blanks are obtained from a three-layer laminate and semi-completed tips are cut out from the prismatic blanks like this, the semi-completed tips can be obtained in large numbers, yield is high, and the manufacturing cost of the tip can be reduced.

Abstract: A shaving device that defines a substantially cylindrical volume to receive an index finger of a user. Rotation about the index finger under control of the adjacent thumb and middle finger provide precise finger-tip control of the pitch, angle and pressure applied the fixed or replaceable shaving blades.

Abstract: A circular saw including a frame, a drive means mounted to the frame coupled to a planar saw blade for rotation about a drive axis within a cutting plane and a base pivotably mounted to the frame about a first axis substantially parallel to the cutting plane and a second axis which is generally substantially parallel to the drive axis. In one aspect, the relative pivotal movement of the frame about the first axis is determined by a trim adjuster including disengageable position locator which is operable to provide a plurality of predetermined discrete engaged positions and a locking means for locking the position of the frame relative to the base over a continuous range of settings. The invention also provides a mounting assembly including a course adjustment means and a fine adjustment means to determine the pivotal movement of the frame about the second axis relative to the base.

A handle member is secured to the planar body member and extends upwardly opposite the wheeled axles. A crossbar can be attached to the handle member. A user grasps the handle member, or crossbar, and rolls the planar body member forward on the wheeled axles to cut a sheet of material passing into the cutting notch.

Abstract: A center marking assemblage or kit consisting of a stylus retaining quill having an upper end and a lower end; a stylus having an upper driving end and a lower scribing end, the stylus being slidably mounted within the stylus retaining quill, a group of differently sized scribing end centering guides, each guide among the group having a lower circular diameter matching a common drill bit size; and consisting of quick disconnect couplings integral with the lower end of the stylus retaining quill and with the upper ends of the scribing end centering guides, such couplings allowing such guides to be selectively and alternately attached to and removed from the lower end of the stylus retaining quill.

Abstract: A folding tool such as a knife or multitool and the like has a resilient lever arm formed in a body portion. A blade pivotally connected to the body is movable between closed and open positions. A blade locking pin is carried on the lever arm, and in the normal resting position the blade locking pin engages the blade. When the blade is in the open position the lever arm biases the locking pin into locking engagement with a notch formed in the blade tang, thereby locking the blade in the open position. Actuating the lever arm disengages the locking pin from the blade, allowing the blade to be moved into the closed position. The blade may have a second notch or hole formed in the tang for engagement of the blade locking pin when the blade is closed, thereby locking the blade into the closed position.
