Abstract

6987. Moulton, W., and Webster, J. March 22. Engraving. - Relates to engraving-mechanism of the Shields type, which may be in the form of an attachment for ordinary machines, whereby designs may be produced on the same scale as the pattern plate. The tracer bar d slides longitudinally in a bracket f connected by a bar g to the bars h carrying the tools, so that the full lateral movement of the tracer is communicated to the tools. The bar d is secured to a saddle c<1> attached to a bar c carried on rollers running on the transverse bar b, which connects the side rolling bars a. The bars a impart movement to disks j on the mandrel of the roller to be engraved. The disks are interchangeable or may be brought up to the size of the roller by detachable rims j<1> secured by clips j<2>. The machine may be adapted for engraving flat surfaces.
