Several preferred embodiments are disclosed for a tool-less blade clamping apparatus for a reciprocating tool of the type which has a reciprocating plunger which has a tool attachment receiving slot for receiving a tool attachment of the type that has a shank portion. The clamping apparatus has an unclamped position and a clamped position. In the unclamped position, a tool attachment can be easily inserted and when it is in its clamped position, the tool attachment is securely retained. The preferred embodiments have at least one spring biasing the apparatus toward the clamped position, a releasable retaining mechanism for holding the apparatus in its unclamped position after being placed in that position. When the blade shank portion is inserted into the slot a predetermined distance, the shoulders of the shank portion release the retaining mechanism to move it to its clamped position. When a blade is to be removed, the clamping apparatus needs only to be moved to its unclamped position by manually rotating the outer sleeve or collar, and the blade is normally ejected from the mechanism by contact with the blade shoulders as it reaches its unclamped position.

A child carrier is provided. The child carrier has independently adjustable shoulder and waist straps that allow interchangeable use on either hip of the user. The child carrier has a removable storage container that is selectively connectable thereto.

A system that enables axis-to-axis targeting of an instrument placed within a drill bushing includes a computer, a probe, and a pair of sensor planes mounted to a drill bushing so the planes are perpendicular to one another. The probe has two drive coils that may be mounted near its distal end. The two coils are placed close to one another and are oriented so that when they are selectively coupled to an alternating current source they generate magnetic fields that are orthogonal to one another. The computer receives electrical signals from the sensors in the sensor planes and computes target position, bushing alignment, and bushing orientation values. These values may be presented on a display associated with the computer or used to illuminate directional arrows associated with the drill bushing.

A shoe is provided with a writing surface so that temporary expressive indicia can be applied to the shoe. The writing surface is preferably in the form of a side surface of the shoe extending between a tread and a foot contacting surface of the shoe. The side surface is preferably formed of patent leather compatible with a dry erase marker provided as a writing implement. In a most preferred form of the invention, the shoe includes a bore which acts as a housing for the marker or other writing implement to conveniently store the writing implement when not in use. The bore or other housing also keeps the writing implement fresh by sealing the writing implement within the bore when not in use, especially when the writing implement is a dry erase marker.

A tapping device is configured to be used within a drill press or lathe or other device capable of holding a cylindrical object. The tapping device has an upper projection for being axially fixed in, for example, a drill press. The remainder of the body of the tapping device is rotatable with respect to the upper projection and includes side handles for providing handy mechanical advantage to the turning of the tapping device body. The end of the body opposite the upper projection includes a chuck for holding a typical tapping tool. The projection is connected to an internal shaft which engages the body of the tapping tool and is spring biased to draw the projection and internal shaft within the body of the tapping tool. Conversely, when the tapping tool is supported in, as an example, a drill press chuck, such spring urging acts to lift the body of the tapping tool in the direction of the projection. The number and nature of the springs which act between the internal shaft and the body of the tapping tool, as well as the dimensions noted can be widely varied to accommodate a variety of force versus displacement characteristics especially taking into account the mass of both the body of the tapping tool and its tap chuck. An adapter is provided for quick change of socket supported taps.
