Abstract: A leveraging apparatus for a drill is disclosed for drilling a workpiece. The apparatus includes a bar body that preferably has a plurality of attachment means there along. A carriage is adapted to slidably receive the bar body and further includes a forward side, and a lower side for mounting with a drill clamping means. An elongated handle is pivotally connected at a distal end thereof proximate the forward side of the carriage. The handle is pivotally, and preferably selectively, attached to the bar body. The clamping means may include a bracket having an aperture therein for selectively receiving the drill therein. A foot means extending away from the bar body is fixed thereto with a bar body attachment means. The foot means is used to brace the workpiece while the handle is used to move the carriage with respect to the bar body to drill the workpiece.

Abstract: The present invention is a filter for use with an oxygen delivery system. The filter includes a made up of a housing, with a pair of inlets and which defines a variety of internal features and structures which will be described here below. The filter operates by conducting the oxygen from a source through the first inlet and into a receiving chamber form this receiving chamber through a foam and charcoal filter and back out through an outlet for use by a user. This filter and system provides a way for delivering cleaned, filtered oxygen to the intended user through a delivery device such as a mask or a nasal canula.
