Appleton's dictionary of machines, mechanics, engine-work, and engineering. remity of 492 PIN-MAKING MACHINE. the portion 8d of the feeder-frame, furnishing in front towards the vertical shaft c (or the centre of therevolving table D) a vertical plain surface at right angles to the line in which the wire is fed into themachine. To the aforesaid vertical face of the portion \§d of the cutter-stand is fitted a steel plate has a hole through it of a suitable size and in a proper situation to let the wire passthrough it in a straight line from the feeder to the pointing chuck, into which chuck the wire enters,previous to a portion of it being cut off to form a pin. A steel cutter 18 is fitted into a groove orsocket in the cutter-stock 19, so as to admit of its being adjusted and fixed therein by screws, and tccause the cutting edge of said cutter to lie flat against the plate. The cutter-stosk 19 is jointed to thevertical portion 16<Z of the cutter-stand by means of a centre-screw 22, so that 19 forms the short armof which 19 c? forms the long A small projection or plate 19c extending from the edge of the arm 19c? of said lever rests upon theperiphery of the cutter-cam 6, and a stud standing out laterally from said arm 19c? at right angles tcthe plane of its motion on its centre 22, rests against the side of said cam 6, on which side the actingparts of said cam are formed. The cam b is circular and concentric with the shaft B on which it isfixed, and has its acting parts formed on the side of it next to the aforesaid stud of the lever is a recess or low part, which is connected by an inclined portion at one of its extremities to theraised part 62, and at its other extremity to the tooth or pivot 63 ; the portion or face 62 is a plainsurface coinciding with the plane in which the cam 6 revolves; and the tooth 63 is a wedge-shapedprojection raised upon one extremity of the face 62. A spiral spring 235, which connects the extrem-ity of the arm
