H. A. Clum. Rochester, New York. Patented May 29, 1860.

This exceptional wall barometer has a walnut case and is decorated with boldly formed ripple moldings that retains it’s original finish. This form is very unusual. Note the extensive use of ripple moldings and the decorative acorn shaped finials. The top is surmounted by a cornice type molding. The upper section forms a frame around the glass panel. The glass panel allows one to read a paper scale measuring the changes in the mercury. It is in this location that the instrument is signed by the Maker and lists the patent date. The waist is long and narrow. Here the center tube is fully exposed and provides a stark contrast to the dark color of the case. This center tube is flanked by two fully turn rods the from the waist. The base section is an inverted cornice molding or form which is of a slightly smaller scale compared to the one found at the top of the case. As a result, the overall proportions are excellent. This is a large instrument which measures approximately 37.75 inches long and 8.5 inches wide and is 2.75 inches deep. It was made circa 1860.
