Abstract: A multiple utility pool accessory, for attaching to a standard pool service pole and performing multiple pool maintenance duties. A handle, having a handle open end attaches onto the pool service pole. A main assembly cross bar attaches to the handle opposite the handle open end, and extends transverse to the handle. A pair of angle brackets each comprise a projecting leg having an outer surface, and a slotted leg. The slotted leg of each angle bracket is pivotably secured to the main assembly cross bar, so that the angle brackets are selectively pivotable between a narrow position wherein the outer surfaces face each other, and a wide position wherein the outer surfaces face away from each other. Variation between the wide position and narrow position allows a variety of attachments to be secured between the angle brackets, including a grinding wheel for scraping debris, chlorine tablet for concentrated application of chlorine, and a collector basket for removing loose debris.

Abstract: An improved automatic damper for furnace vent pipes is disclosed. The damper is part of a mounting mechanism which is installed in an existing furnace vent pipe and attached to a motor for operation of the damper. The motor is secured to a mounting bracket which in turn is secured to a collar mounting bracket which has two sections and is removably secured around the existing vent pipe. One section of the collar mounting bracket has an elongated slot which is used as a template for preparing an access slot in the pipe for the damper. Both of the sections have pilot holes in them which are used to make corresponding pilot holes in the vent pipe. After the slot and pilot holes are prepared, the two sections are removed and the damper is installed in the slot in the vent pipe. Thereafter, the two sections of the collar mounting brackets are reinstalled on the vent pipe, but in opposite positions thereby covering the access slot and securing the damper in place.
