Patent number: 5897434Abstract: A detachable chimney cap hood which can be attached to the side walls of a chimney cap without the need for nuts, bolts, screws or tools and allows the hood to be later removed manually. The hood includes a cover portion and one or more locking clips attached to the cover portion. Guide pieces can also be included to align the hood onto the chimney cap. The locking clips and guide pieces hold the hood in place. The hood allows a person to attach and remove the hood manually without a wrench or other tool when a chimney flue needs to be cleaned. This feature is especially desirable when the chimney cap is cemented or otherwise permanently affixed to the chimney flue because the hood of the chimney cap must be separately removed in order to access the one or more chimney flues covered by the cap.Type: GrantFiled: October 24, 1997Date of Patent: April 27, 1999Inventor: Christopher B. Arbucci

The chimney cap's connection mechanism also strengthens the assembled chimney cap by providing multiple points of connection. Each side piece has a insertion portion with internal protrusions which fits inside a receiving portion of an adjacent side piece. A roof is then attached the side pieces to complete the chimney cap.Type: GrantFiled: September 12, 1997Date of Patent: March 2, 1999Inventor: Christopher B. Arbucci

Patent number: 5816288Abstract: A protective vent for a water storage tank having an inner flexible fine mesh screen and an outer heavier more rigid screen with a wider mesh. Both screens are mounted on a frame structure under an extending upper protective cover. Air from the water tank can communicate with ambient air after passing through the two screens. The outer screen acts to protect the tank and the inner screen from birds, grasshoppers and large insects while the flexible wrinkled inner screen protects against frost and smaller insects entering the tank. Fiberglass may be used for the fine inner screen and galvanized hardware cloth for the outer screen. The vent is constructed to be mounted over an existing vent stack from the storage tank. On those water storage tanks whose venting capacity is no longer adequate and an increase in air flow is desired, a new larger diameter vent stack can be installed in place of the existing smaller stack with this protective vent system.Type: GrantFiled: May 9, 1997Date of Patent: October 6, 1998Inventor: Clyde H.
