Abstract
13,708. Lock, W. H., and Barr, M. July 3. Engraving. - Relates to pantograph engraving- machines. The tracer 10 and tool spindle 33 are carried by ball-and-socket joints 35, 36 on a double telescopic rod 37 swinging about a universal joint 38. The tracer and spindle pass through ball joints at the intersection of the lever 21 with the parallel levers 14, 15, horizontal movement being permitted by slots and slides as shown. The pivots 22, 16, 17 of the levers are in a straight line, and the parallelism of the levers 14, 15 is maintained by a link 18. The tracer and spindle also pass through the ball joints of an exactly-similar linkage 21<a>, 14<a>, 15<a> below. The lever 37 may be dispensed with, and the part of the standard 11 to which the linkages are pivoted be arranged to turn on horizontal pivots, the lower linkage turning on a horizontal axis mounted on this part. When two-dimensional work only is required, the apparatus may be simplified, the lower linkage being dispensed with.
