New Routing Machine
In most kinds of business at the present day wood engravings have come to perform an important part. Correct ideas of a machine, or almost any other object or grouping of objects, are widely disseminated by means of printed cuts. The preparation of these cuts necessarily engages a great deal of skill. The representation of objects lo be illustrated is first made upon a smooth block of boxwood, either with a pencil or by photography, then engraved. The wooden block is seldom used directly for printing as it is liable to be spoiled, but electrotyped or stereotyped plates in type metal are made from it at comparatively small expense. After these plates are cast the parts must be cut away where the imprint is to appear white. This is done by routing machines, a newly improved form of which is shown in the first illustration on this page. It is constructed entirely of iron, takes up but little room, and is so easily accessible on every side that the operator can work it without any trouble.
Power is communicated to the upright shaft in the corner of the table from below, and thence by pulleys and belts to the steel cutters, which revolve seven thousand times a minute, and which, by means of the double lever, can be brought to any point with ease and precision.
The machine also has a circular motion, and an arrangement for cutting straight lines. A spring rest prevents the tool from touching the plate till pressed down by the operator. The stand contains shelves for tools, reached by the door shown in the cut. This machine will work a plate 21 x 28 inches. The manufacturers are R. Hoe & Co., New York City, and London, England. |
