Description: |
| British patent corresponding to U.S. patent no. 769,814 granted to George W. Bufford and George F. Hickman on Sept. 13, 1904. C.L. Perry was the British patent agent.
J.H. Williams & Co. VULCAN CHAIN PIPE VISE was based on these patents.
Abstract: "Relates to improvements in the chain pipe vice described in Specification No. 23,811, A.D. 1903. To the chain D at e is pivoted the screw E, which passes through the aperture f, the lower part M of which is shaped to form a seat for a rocking head H. The head rests on or forms part, of the adjusting-nut F, which carries a pivoted handle G and is flanged at L to rest on two lugs at opposite sides of the aperture. The loose end of the chain D hangs in the slot a, which has two series of inverted steps J, with which engage the chain pintles d, the walls of the slot a being recessed at N to receive the pintle next adjacent the one engaging the steps."
Note: Early British patents (pre 1916) were numbered by the year and started at patent #1 at the start of each year in January. The patent # used in DATAMP represents the year of registration and the patent # (with "leading zeros" interposed to make the number total nine digits). This patent is #19,711 of the year 1904. |
