A Geometrical Carving and Comer-Block Machine, Fig. 8, patented by S. Y. Kittle, is used in making interior wood-decorations for ceilings, such as corner-pieces, center-pieces, borders, etc. There is a frame which has a square table or box with a flaring base, and a continuation having a gap somewhat in the manner of a band-saw or drill-press frame; this carries a vertical router-spindle, the pulley of which has one bearing above and one below, the belt passing over two idler-pulleys at the back of the frame and down over the main pulley which is at the bottom of the machine, at the back, the shaft running fore and aft, and hence at right angles to the router pulley-shaft and the idler-shaft. The table has vertical motion by a rack and pinion, and horizontal adjustment, as well as tipping motion for certain classes of work. There are adjustable stops to regulate the depth of cut; and the table has an index for dividing and regulating its circular movement. There are suitable clamps and jaws for centering and holding down the blocks, and the whole table is counterbalanced, so as to move more readily up and down by a hand-lever. The router-shaft pulley is covered by a casing, which protects the operator, and keeps oil from being slung over him and the work. By this machine, work of the class done in metal by a rose-engine or geometrical lathe may be effected; and by an attachment the operator can cut designs on material of any length, as in the case of long boards on mantelpieces. Another attachment is for routing or duplicating operations in line for fancy moldings, consisting of a table with rack and pinion-feed, that may be fed along by a hand-wheel, or by a lever and ratchet, as desired. |
