yThe object `of :myinvention is to .feed the? .\Wire1blanks,'to be yswaged Iinto the form and. :size .required for the blades of sewing-:machine -needles,.to .the dies of a sWaging-machinein .such a manner as .tdcauSesaid-blanks to be -operated upon by -saiddieswith accuracy and uniformity, and to :followfeachother in rapid succession; and -my.improvementfconsists .in-I applying 'and combining certain mechanical vdevices .and movements 5in suchamanneras. :.to.control, supply, and feedfsaid blanksauto- Amaticallyv duringvsaid swaging operation, and
.thus accomplish the l desired result.
To enable rothers .skilled .in thefart to .make` and use my improved machine, 1I vwill now proceed to describe the'construction and oper- :ation of :the same, with-reference totheaccorn- .p anying drawings.

Hl and 6. l
1 A quantity of wire blanks of the required diameter forthe shanks of the needles to be swaged, and of sufficient length to supply the amount of stock for the blades of said needles, are nowV placed in the vertical opening of the :hopper I, as shown in the drawings. Motion being now communicated 'to the cam C, in the direction of the arrow drawn upon the same, by meansof the pulley D, gearing, or equivalent device, and to the pulley K and gearing connected therewith, in either direction, a reciprocating motion will be imparted to the slide B by means of said cam and levers F and G, anda revolving motion imparted to the'spinf dle g and griping-chuck t', the free end of the blank which extends from said griping-chuck being in the meantime forced into the grooves, which are between the swaging-dies during the forward movement of the slide, causing said :blank to be reduced to the size of the groove f by the rapid vibrating motion of said dies upon -said blank, the extreme stroke of the slide be- ,ing regulated so as to leave a portion of 4the lblank unswaged'for-the shank of the needle, `as shown in the drawings, Fig. 4.
operating the lever Q. S is an adjustableV bearing secured to the side of the frame A for the purpose of receiving the adjustable bar R. T is a screwfor regulating the position of 'the `bar R. VV are studs secured to the forkedv end of the slide-lever G, and fitted loosely to the groove to, in the head of the adjusting-screw H. x is a stud secured to the end of the cam-lever F, and made to slide freely in the groove in the cam C. y is a nut tted to the adjusting-screw H for the purpose of securing said screw in its proper position.
I will now describe the practical operation of my improved attachment, with reference It is to be When the slide B reaches the extreme stroke, above` described, the wire plunger ois :in such a positionwi'th respect to the blanks `in hopper I as to allow the bottom blank in said hopper to fall just in front of the end4 of the thimble p is forced from the jaws ofthe gripingchuck by means of the forkedbar L, bars t and t', double screw u lever s, rockshaft q, and lever Q, the bar S being so adjusted with respect to the lever Q as to come in contact with said lever immediatelyafter the removal of the swaged blank Vfrom the dies, and force the thimble from the jaws of the griping-chuck by means of the oscillating motion of said lever and rock-shaft q, thus freeing the swaged blank from the jaws of said chuck, and allowing said swaged blank to be removed therefrom `while the plunger o is forcing a new unswaged blank into its position in said chuck, during the remaining portion of the backward movement of the slide, as shown in the sectional drawing ofthe same Fig. 5; and when the slide has reached its extreme backward stroke, the plunger has forced the new unswaged blank just in front of the stop j, which falls behind said blank by the force of the spring k, in the manner shown in the sectional drawing, Fig. 4, to prevent said blank from being forced' from its proper" position in the griping-chuck during the operation of swaging the same.
The unswaged blank bemg now 1n its position in the gripingchuck at the extreme backf ward movement of theslide B, a forward movement of said slidenow takes place, soonafter which the lever M comes in contact with the bar N, before said blank `has reached the swaging-dies, as shown in the drawings, Fig. 1, and forces the thimble p back upon `the jaws of the griping-chuck by the action of the lever M, rock-shaft q, and mechanism connected therewith, in a similar manner as bcfore described for removing the thimble, but
in an opposite direction, thus securely holding the blank in the jaws of the griping-chuck during the remaining portion of the forward movement of the slide, while the swaging-dies are in contact with said blank.
It should be noted that the gearing connectedwith the spindle and griping-chuck need not be applied to the latter for revolving the same when this attachment is applied .to that class of swaging-machines which employ revolving swaging-dies. The above-described mechanism is adopted when this attachment is applied to that class using stationarydies,
as itis necessary to revolve the blank during Thus, with to the dies of a needle-swaging machine, the plunger o, in combination with the slideB, hopperl, spindle y', and griping-chuck c', arranged substantially as shown, for the purpose of forcing an un'swaged blank fromsaid hopper through said spindle into its proper position in said griping-chuck,andremoving a swaged blank therefrom during the backward movement of said slide, substantially as and for the object set forth.
2. In combination with the griping-chuck i, the stop j, and spring k, arranged between the jaws of said griping-chuck, substantially as shown, for the purpose of preventing the unswaged blank from being forced from its proper position in said griping-chuck back into the spindle g during the swaging operation upon said blank, as specified.
3. In combination with the griping-chuck i and thimble p, the forked bar L, bars t and` t', double adjusting-screw u, lever s, rock-shaft l q, and levers M and Q, for the purpose of forcing said thimble upon the jaws of said chuck,
or removing the same therefrom, substantially as shown and described, and for the object set forth.
4.-. In combination with the lever M, the adjustable bar N, and adjustable bearing O, ar-
ranged substantially as shown and specied,
for the purpose of operating said lever and parts connected therewith during the forward movement of the slide B, at the time and for the object set forth.
5. In combination with the slide B and lever Gr, the adj listing-screw H, connecting said slide and lever, and arranged substantially as shown and specified, for the purpose of regulating the extreme forward stroke of said slide and griping-chuck attached thereto to a proper position with respect to the dies o f the sWaging-machine, for the object set forth.
