Abstract: Disclosed are vises for machining work pieces. More specifically, disclosed may be a vise compatible with interchangeable or reconfigurable jaws positioned along a base with either (a) parallel and lengthwise series of securing ports or (b) parallel and lengthwise tracks.

Abstract: Disclosed generally is a face plate for a vise that is capable of gripping multiple work-pieces of different sizes at the same time. In one embodiment, the disclosed subject matter may be a vise face plate comprising: a base with an upper compensation structure and a lower compensation structure; and, wherein the upper and lower compensation structures define two sets of working surfaces. In use, the plate may be secured to a movable jaw so that the working surfaces may be employed to clamp a plurality of work pieces between the working surfaces and a fixed jaw.

Abstract: Disclosed generally is a quick change face plate for a vise.

Abstract: A floating barrel nut may be used to retain a nut in a seat of a segmented cylindrical slug. In one embodiment, the barrel nut according to this disclosure may comprise: a nut with a threaded shaft and a flange that is chamfered on its lower end; a cylindrical slug that has been segmented along a plane that is parallel to the cylindrical axis, said slug having a head and a foot; two pins; wherein said nut is configured to float between the head and foot of the slug; wherein said shaft features an indentation on opposite sides thereof; and, wherein said pins are attached to the head and foot of the slug and sit in the indentations of the shaft. In another embodiment the pins are bent around the shaft.

Abstract: A stair climbing exercise machine comprises an upright frame and a pair of reciprocating left and right pedals pivotally mounted on the frame for independent movement between raised and lowered positions. A hydraulic control system is connected to the pedals to provide resistance to downward movement and to return each lowered pedal to a raised position independent of operation of the other pedal. In a preferred embodiment, a TV screen is mounted on the frame and is controlled by a computer to display certain information during an exercise routine, which may be overlaid on a TV program. The computer may also control the duration and difficulty of each exercise routine.
