Improved Combined Mortising and coring Machine
The use of reciprocating mortising machines for recessing the stiles of shades for the reception of the ends of slats is not uncommon. Upright and horizontal boring machines for those blinds in which the slats may be turned have also been extensively used. This machine, represented in the engraving - which was patented through the Scientific American Patent Agency some time ago - is entirely automatic in its operation, and either bores the round holes for the reception of the pivots of turning slats, or mortises the recesses for the reception of the ends of those slats designed to be permanently fixed at a certain angle. The latter are made on this machine by means similar to those used in boring a simple round hole, the tool being a reciprocatory or traversing burr or bit, which can be used on hard wood, knotty pine, and other obstinate descriptions of wood, where ordinary machine chisels fail. The machine is self-operating in all its parts, and all the workman has to do is to put in the stiles and set the machine in motion, when it does its work, and, having done it, stops.
As seen by the engraving, the machine is very simple in construction, made entirely of metal, easy of operation, and durable. Agents for its introduction throughout the United States are wanted. For particulars address Martin Buck, Lebanon, N. H.
