TO ALL PERSONS TO WHOM THESE PRESENTS MAY` COME 'Be it known that I, Jnssn S. PERKINS, of Lake Village, of the county of Belknap, of the State of New Hampshire,--have invented a new and useful Machine for kMaking from Wire the Blanks or Shanks of the Needles of Knitting-Machines; and I do hereby declare the same to be fully described inthefollowing specification, and represented in the accompanying drawings, of whichl A Figure 1 is a top view, Figure 2 a longitudinal section, and j Figure 3 a rear end elevation of such machine.

. The blank (or t shanl:,"as usually termed'by operatives,) which the machine makes,*hasv the form as represented in side'view in fi'fg 4. After having been so made from-wire by themachine, the blank has to be iattened, slitted, pointed, notched, bored, and bent by other mechanismbefore it becomes in a proper form to re'ceive the latch or tongue used for closing its h'ook 'usually made o'n the front end of the blank.

My machine forms each blank with a projection having the form as shown at `a in fig. 4, and, besidesthis, my' machine cuts the blank lfrom the piece of wire from which it is to befmade, Ythe mahine producing from a coil of wire a. succession of such blanks, until such coil maybe entirely cutQup or converted into the blanks.

In the drawings, A 4denotesjthe frameof the machine, it having a driving-shaft, B, extended .across it at its rear part. This frame also supports, in suitable uprights or standards, a a', another shaft, C, which is revolved by means of a train of gears, D E F, arranged as represented. The gears D and E are fixed on the Vtwoshafts, and the th-ird gear is arranged between the other two, and supported by` a journal, ZI, extended from an inclined bar, c, composing part of the frame. v j l v Atfthe rear Iend of the' frame A are two jaws, d e, which are connected by a clampscrew,f, which goes through the upper and screws into `the lower of such jaws, such lower jaw being projectedfrom'the frame. i

The wire W, in its passage intothe machine, first goes between the two jaws d e, and bythem will be held l by friction suihcient to 4prevent it from being forced backward during the retraction of the carriage G of the machine. v

From the jaws the wireis extended' through'a die,f, projecting upward `from ancljbeyond the end of the movable carriage G, in manner as represented in igQQ. This carriage is to be supported within the frame A, so as to be capable of being moved horizontally .and longitudinally theiein. A cam, H, fixed on the drivingshaftfserves, when revolved by such shaft, to advanceA the carriagawhich afterwards will be retracted by means ofa spring, I, connected to it, and supported on an arm, K, arranged as represented in tbedrawings. v v V In advance of the diefis' another die, g, which projects upward' from a lhorizontalA shaft, 7i, provided with a rctrac-tive spring, z', which is coiledaround Vthe shaft. One end of the spring is attached to the-shaft, andthe other'to the frame. Furthermore,"an arm, k, 'extendeddown fromthe shaft 7i, brings up against an adjustable stop, l, screwed through' the front-end of the frame.

lNear the said frontend of the frame is another movable carriage, L, which rests against-the inner end of an adju`sting-screw, m, and carries a die, n, .formed and arranged in manneras shown in'the drawings.A i A third carriage,d\I, supported in groovesv madein the two standards, a a, so as to bec'apable of beingY moved vertically, supports a bending-die, o, 1and a cutter,p, and is forced downward by a,cam, g, and is retracted' by a spring, r, the said cam q being fixed on the' shaft C. i i 'The operation ofthe machine may be thus-explained:

The wire, after having been passed through the dief, and upon andbeyond thetop of the lowebender and cutter g, the carriage M will next descend, -so as to force the upper bender o down upon the wire, and between the two diesfg. In the mean-time the wire willbe cut oif by the action of the two dies g cndp, and the part Vin advance' of the diefwill be bent down into a U-form. This having been done,`the carriage M will be .immediately raised upward to its highest position, and the advance of the carriage G will follow. I n going forward,

so,so4 2 the carriage G will press against the front lower bending and cutting-die g, and move it out of the'way, and pass in, and at' the same time will draw the wire forwards, and force against the die n the part of the wire previously bent in the U-form. The legs of this portion will be compressed together, and thus the parta, shown in-g. 4, willrbe formed. Next, the carriage G will boretracted, the wire will remain at rest, and the die f will be moved beek to its rearmost position. The carriage will next descend, and sever the blank from the wire.

I claim the combination of friction-jaws d e, or the equivalent thereof, and the dies and cutters fg 'n o p, arranged and provided with. mechanism substantially as described, for 'operating them in manner and for the purpose as speoied.
