We believe that hollow chisel mortising ma-chines have hitherto been made by one or two firmsonly, but the Berry & Orton Company, whose ma-chine we illustrate, are now seeking for a share ofthe business of supplying the demand for them—ademand that is destined to be much larger than atpresent, as the merits of these peculiar machines be-come better known. In placing this machine on themarket the Berry & Orton Company have made it astudy, both in the design and arrangement of parts,to make it the most complete hollow chisel mor-tiser ever offered. They claim the following point THE MASTER MECHANIC. Febsuabt, AUTOiMATIC COAL CHCTE UOALINtl of superiority over machines of other manufacture:A much stronger, more substantial machine, andone less liable to get out of order; longer belts,which are more accessible, being all outside theframing of the machine; the driving power for forc-ing the chisel into the wood is placed as nearly thecenter of the chisel as possible, which is from 6 10 in. nearer than on other machines; the support-ing of the timber to be acted upon is directly backof the table and is in a direct line of the chisel; theframing of the machine is such that the thrust whilemaking the mortise is taken both above and belowthe chisel, hence the soring of the machine is re-duced to the minimum, and the chisel, after beingforced into the wood, is drawn with much moie easeand less liability to break than when the strain istaken entirely below the chisel; a double set of stopsis supplied for regulating the position of mortisesvertically; it is a much c
