Oilwick Lamps/Aluminum Pat Apd For Comparison

Oilwick Lamps

Aluminum Pat Apd For Comparison.JPG - ALUMINUM LAMPS - Although both of these cast aluminum lamps are thought to be made by the same manufacturer following the Hammond patent, little is known about the manufacturer or production dates. Only a few aluminum oilwick lamp varieties are known and the two shown here are the more common. An unmarked flat back aluminum wick lamp was made by the American Safety Lamp and Mine Supply Co. of Scranton, PA and included in an 1896 advertisement (see Moon, Mining Artifact Collector #14, p 22). That same company made a second unmarked aluminum wick lamp called the Indestructible that was advertised in 1912. As for the two lamps shown here, there are notable differences other than the left lamp is used and the right lamp is unfired. Both are the same external size, but the lids are quite different. The lid on the left lamp is thicker and 1 1/8 in. dia. while the lid on the right lamp is 1 1/4 in. dia with a smaller size vent hole. Additionally, the right lamp has a conical vent hole protrusion on the lid underside while the left lamp is smooth on the underside of the lid. Since both lamps have the same top opening dia., the lamp on the right provides a thin rim extension about the opening. The hook attachment on the right lamp is considerably larger than that on the left. Both are marked PAT APD FOR but the letters on the left lamp appear larger, rougher in appearance and with a slightly curved pattern. The letters on the right lamp are thinner and appear in a straight line. Likewise, the number 3 appears below the marking on the right lamp. The high cost of cast aluminum lamps around the turn of the century clearly limited ownership to the most affluent in the mining community.
