Figure 36.—Combined torch and battle ax, 1884, as shown in patent 309370, issued December 16, 1884. TIN TORCH, 1880 Figure 32 No example found. A second torch was patented by Hermenegilde Prefontaine in 1880, securing the lamp at diametri- cally opposite points above its center of gravity to the end part of the two arms of a frame. In its middle, the fraine has a socket, through which a pin pivots and secures the frame to the handle. The object of this invention is to keep the lamp and the bifurcated frame always in a vertical position by having their weight serve as a counterbalance. Through the end of the arms of the supporting device are pivot perforations. The supporting frame, slightly offset, is made of wrought or sheet metal, the lower portion being reinforced by a V-shaped metal strap. The pin around which the torch pivots passes through the frame and strap and is fastened into the head of the staff. The patentee claims this to be an improvement over the method devised l)y Moritz Saulson in patent 183332, dated October 17, 1876, and assigned to Minnie Saulson (fig. 23). Similar to this improve- ment, Prefontaine devised a second improvement on the same patent in which the V-shaped reinforcing strap is replaced by a U-shaped single piece of metal bent at the top and bottom to gi%'e it lips, but open on one side and the ends. The pin passes through perfora- tions in the lower portion of the metal strap and through the lips into the staff. No patent models were submitted to the Patent Office on these inventions. TIN TORCH, 1880 Figure 33 No example found. This torch is approximately the saine as the one illustrated in figure 32 with the exception of the shape of the bowl, and is from the same patent drawing.
