The wire supporting the torch loosely coiled around the .staff and the ends are brought upward on opposite sides and bent toward each other at a point near the plate, which is pivoted on the end of the staff by a screw. The dis- tance between the coil and the shoulders of the bracket is not more than two or three inches. These torches were designed especially for torchlight processions. TIN TORCH, 1880 Figure 31 USNM 227739 (Becker Collection) An improvement in the pivoting frame appeared when Hermenegilde Prefontaine of Troy, New York, in 1880, patented a frame made of one single piece of wire coiled at the bottom to resemble a mandrel rod. A nail passed through the coiled wire fastens the supporting frame to the staff. The claim for this invention was to simplify the construction and thus cheapen the cost of the torches.^ No patent model was submitted at the time the patentee submitted his request. The diameter of the torch bowl is 3)2 inches at the top and 4 inches at the bottom. The bowl is 3 inches high. ^ Claim 3 of the original patent request was denied in that it interfered with a patent on coffeepots previously acquired by Gibson (patent 98244), issued December 28, 1869. This claim had to do with the manner in which the supporting device was received in the sides of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States National Museum; Smithsonian Institution; United States.
