Abstract: An evaporative cooler is disclosed incorporating a horizontally disposed hollow cylindrical pad mounted for rotation above a water tray. The cylindrical pad extends into water placed in the tray and is rotated to continuously immerse a portion of the pad. The pad is supported through a plurality of rollers contacting circumferential bands positioned thereon; the rollers providing all of the support and all of the rotational force to the cylindrical pad.

Abstract: A longitudinally extending support is secured to the table of a table saw to which a guide rail is secured. A saw fence, having a shoe secured thereto, includes a clamping arm extending therefrom. The shoe slidably engages the guide rail and may be clamped together with the fence to the guide rail. A scale is formed on the guide rail and an index is attached to the shoe and positioned to register with the scale.
