Abstract: An exercise device, in particular an exercise device that can be attached to a conventional walker so that the user can operate it while supporting himself with the walker. The device features a base bar that can be attached to at least two legs of a walker and also attached to a second cross bar fit with support rollers, such as pulleys. A cable extends substantially the length of the cross bar, hangs down near the ends of the cross bar, and is disposed on the rollers. On one hanging end of the cable is attached a weight or similar resistance mechanism and on the other end is attached a stirrup or the like suitable for insertion of the user's limb. The height of the stirrup can be adjusted for various exercises and the user can exercise by moving his inserted limb against the resistance.

Abstract: A power saw guide assembly comprises a base member adapted for mounting on a saw table and having a circular recess in its upper surface. A U-shaped mounting member defined by a plate portion extending between two legs is rotatably and lockably mounted on the base member for rotation about a vertical axis with the plate portion slidably seated against the upper surface of the base member and a cylindrical boss secured to and extending downwardly from the plate portion seated in the circular recess of the base member. An elongated track member has one end thereof disposed intermediate and pivotably secured to the legs of the mounting member for pivotal movement about a horizontal axis; it has a generally U-shaped cross section defined by a web and two legs, the free longitudinal edge of each leg having a longitudinally extending flange projecting inwardly therefrom in spaced parallel relation to the web.
