E. C. Bennett, of Binghamton, . ., has taken measures to secure a patent for the above. This machine is adapted for planing sash and door mouldings, and also for finishing slats for window blinds. It is furnished with two cutter stocks and other suitable gearing, in order that the twa separate processes we have mentioned maybe in operation at the same time. Or if desired, the sash strips can be rabbetted, and then, as delivered ean be put in on the opposite side and finished. The more peculiar parts of the arrangement consist in the self acting mode of supplying the strips and slats to the bed, and in feeding them up to the cutters ; also in the plan ot giving the bed the necessary reciprocating motion by a tailed segment, which gears into a shifting rack, so that us the segment is impelled by a couple of pins (suitably placed), the change of motion is transferred to the rack, which thus shifts the driving band alternately on to two pulleys. There is another contrivance well worthy ot note, and that is a plan for planing the bottom of the rabbet after it has been shaped, so that it is made quite smooth. This is done hy setting the last of a series of cutters in an inclined position, so that it smooths the roughness caused by the preceding cutters. The operation of the machine is as follows : receptacles or " wings " are filled with slats or sash strips, a weight suspended by a cord is so adjusted as to cause one strip to be fed on to the bed, which proceeds with it to the left end of the machine, a catch now strikes the stuff and drives it under the elliptical springs and against the cutters, the springs being intended to maintain the stuff in position. A similar weight in the other receptacle or " wing " forces another piece on the bed, which is caught and carried to the right end of the machine when the process we have described is repeated.
