Research Facts
Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008; bellows were used to power flames used in soldering metals for crown and bridgework into the 20th century; the Buffalo Dental Mfg. Co. was founded in part by Dr. George Burwell Snow, inventor of the Face-Bow and New Century articulator; he was president of the company off and on between 1869 and 1901, when he formed the Snow Dental Co.; a No. 10 B model of this bellows is found in H.D. Justi's 1888 Illustrated Price List, though bellows with similar designs are still found in later years, including in a 1923-24 Claudius Ash & Sons catalogue; manufacturer's stated that by reversing the position of the bellows, this design did away with the risk of mechanical injury to the disc and would keep the valve from picking up dirt from the floor, keeping the bellows cleaner and in better working order
