To all whom 'it may concer/n.'

Be it. known that I, PAUL BoHIN, a citizen of the Republic of France, and av resident of Paris, France, have invented certain Improvements in Needle-Making Machines, of which the following is a specification.

This invention relates to certain improvements in-that class of machines which are particularly designed and adapted for use in the manufacture of needles, and has for its object to provide a machine of this general character of a simple and comparatively inexpensive nature, and of a strong and compact construction, having certain features of novelty and improvement, whereby the needles may be practically manufactured in a rapid andl economical manner without excessive or extraordinary expenditure of time and labor, and without requiring the exercise of any special4 or peculiar skill upon the part of the attendants or operators such as is requisite Where manual labor is employed to the extent which has heretofore been customary in the manufacture of such articles.

The invention consists, in part, in a needle making machine having eye piercing means, wherein means are provided for inclosing the metal wirey or strip from which the needle is to be formed during the operation thereupon of such eye piercing means in such a manner as to lessen or prevent Suchv deformation of said wire or strip as would tend to produce surface inequalities or projections requiring removal before completion of the finished needle.

Another part of the invention consists in a needle making machine having an edwise movable eye piercing punch, wherein means is provided for reducing the thickness of the metal wire or strip from which the needle is to vbe formed prior to the operation of such eye piercing punch, whereby the thickne of such wire or strip may first be reduced for the production of a thinned weakened .poartion therein through which the punch may be the more readily pressed for the production of the needle eye.

Another part of the invention consists in a needle making machine having channeling means operable for the production of thread grooves in the metal wire or strip from which the lneedle is to be formed,

wherein means are providedfor inclosing such wire or strip during the operation of sald channeling means such mclosmg means `having surfaces adapted for molding contact with said wire or strip to mold the surfaces of the same as may be required for the production of the needle 'without the formation of beards or projections such as result from the employment of various other mechanisms hitherto used in the manufacture of needles.

Anotherv part of the invention consists in 'a needle making lnachine having means operable to feed a metal strip endwise in 4position to be operated upon by one or more of the operative devices of the machine, wherein means are provided for retaining such metal wire or strip and said' operative device or devices against relative shifting movement during the action of the latter upon said Wire or strip.

Another part of the invention consists in a' needle making machine having relatively movable members provided with registering concave die surfaces adapted, when one of sch `members is moved toward the other, to be impressed in molding contact with the wire or strip from which the needle is to be formed, and operable, when so impressed, to mold the head or end of the needle.

Another part of the invention consists in a needle making machine having means capable ofl successive operation, the rst to produce eyes at intervals in the length of a metal wire or strip fromwhich needles are to be formed, and t-he second to sever lengths suitable for needles from such wire or strip, wherein the severing means includes die surfaces adapted for registry during severing of the wire or strip and capable of operation to mold the head of the needle.

Another part of the invention consists in a needle making machine having means yoperable to feed a metal wire or strip endwise in position to be operated upon by one or more of the operative devices comprised in the machine, wherein point forming means is provided to which the metal strip or wire is presented for the production of the needle point.

AThe invention further consists in a needle `making machine of the character last above defined wherein severing means is provided operable to sever the metal wire or strip into lengths preparatory to the presentation of such lengths to the 'point formingmeans.

Ano-ther part of the invention consists in a needle making machine having means operable to feed a metal wire or strip endwise in position to be operated'upon by one or' a metal wire or strip is moved endwise past such respective means in such a way that eyes are first produced therein, and the wire or strip is afterward divided into lengths, wherein point forming means .areprovided, together with a device adapted to receive lengths severed from the wire or strip and to carry the saire in engagementwith such point forming means for the production of the points of the needles.

The invention also consists in certain novel features of the construction, and combinations and arrangements of the several parts of the improved needle making machine, whereby certain important advantages vare attained, and the "machine is rendered simpler, less expensive and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in theA claims.

In order that the invention may be the better understood I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a plan view of a needle making machine embodying my improvements;

Fig. 2 is a partial! vertical section taken through the machine in the plane indicated by the line 2-2 in Fig. 1.; Fig. 3 is a, partial sectional elevation ofthe rear portion of the machine constructed as shown in Fig. 1, illustrating certain features of the driving and point forming means which lwill be hereinafter referred to Fig. Ltis a sectional detail view taken transversely and verticallyv through kthe machine in the plane indicated by the line 5-'5 in Fig. 1; Fig. 5 is atransverse sectional view drawn to an enlarged scale showing.l certain` features of the chan lneling means to be'hereinafter referred to;

The movement of shaft A is communicated through a driving belt or band A1 and appropriate pulleys, as indicated in Fig. 4,

lengthwise into themachine parallel with tioned with respect to the turret Das tov operate to grind and form the points" of the needles supported upon said turret during.

such rotatory movement of thev turret as serves to carry said needles'lengthwise along the peripheral grinding surface of said wheel or drum F1.

H represents a stud mounted to turn upon the frame and .driven from the shaft A vextended along one side of the machine and provided at its right hand end, as shown in Fig. l, with bevel gearing J, J1 serving to impart continuous rotatory movement to the feed actuating shaft K, which is directed transversely across the adjacent end of the frame and has its opposite extremity provided with bevel gearing M, M1 which serves` to impart continuous rotatory movement-to an auxiliary cam shaft N journaledupon the frame parallel with the aforesaid cam shaft I, but spaced apart therefrom to permit the interposition of certain of the operative parts of the machine as will be pres# ently explained.

P represents a straightening device supported upon the frame of the machine adjacent to the shaft K, and herein shown comprised of staggered pins between which t-he metal wire or strip from which the needles are tobe formed is led into the ma chine so that bends or kinks may be eliminated therefrom as far as possible, and'b represents a feeding member or gripper engageable with the wire or strip a beyond the straightener yand intermittently actuated during the operation of the machine in such a way as to operate to ldraw the wire endwise pastthe straightening device and also past certain of the other operative parts and to present the extremity thereof to the severing means so that the lengths may be severed therefrom from time to time suitable for the formation of individual needles.

As herein shown, the wire or strip a is fed the shaft D, between the shafts I and N and in a-vertical planeslightly beyond the perimeter of the turret or carrier D1 supported upon said shaft D, and the feedingmernber or gripper I) is mounted upon-a reciprocatory support or carriage Q guided for endwise sliding movement along a path upon the frame parallel with the directionV of feed of the wire or strip a, as shown 1n Fig. 2,v and provided at its outer end with an anti-friction roller b1 engaged by a cam R upon the controlling shaft K, and provided with a retracting spring Q1 operating to press the carriage endwise against the thrust of said cam, 'the structure and arrangement of the parts being such that the cam R operates at suitable predetermined intervals to force the carriage or gripper support Q endwisetoward the turret D1 in such a manner as to permit the gripper B during its engagement with the wire to draw 'the latter endwise to an extent equal .to t-he lengthof the particular needle to be formed.

The feeding member or gripper (I) is mounted upon one end of a lever 26 fulcrumed at 20 upon the carriage Q as shown in Fig. 12 and having a pendent part 27 which is adapted, when the lever'is rocked in one direction, to ,be depressed into gripping engagement with the upper surface of the wire or strip a to grip or clamp the same securely to an abutment 28 upon the carriage, and when the lever is rocked in a reverse direction is adapted to be lifted out of clamping or gripping engagement with the wire or strip, S0 as to terminate the endwise feeding movement thereof and to release such wire or strip from the support or carriage in order that the same may be expeditiously retracted by its spring Q1 after each forward or feeding impulse imparted to it by the cam R. The opposite end of the'lever 26 carries a screw 25 the lower end whereof depends below the said lever and is provided with an enlargement 30 adapted for sliding contact upon the upper face of a cam bar 24 pivoted at 31 upon the frame alongside the guide-way traversed by the slide or carriage Q and adapted to be raised or lowered by means of a vertically .los

directed link 23 which aords connection bet-weensaid bar and the inwardly directed arm of a lever` 22 fulcrumed at 32 upon the frame as seen in Fig. 11 and having an upturned outer extremity engaged by a cam 21 upon forward extremity of the cam shaft N above referred to as clearly shownin Figs. l and 13. By this construction, since the shafts K and N are drivenin unison, it will be evident that byl appropriate arrangement of the cams R and 2l, the latter may be caused to depress the outer end lof lever 22 in such a manner as to elevate the cam bar 24 during such movement of the carriage Q as tends to reciprocate the gripper in the direction of the arrow al in Fig. l, or toward the turret D1, whereby during such movement of said carriage and gripper b the latter will be pressed by the rocking of lever 2G into effective clamping or griprpingA engagement with the wire or strip a so as to feedl the same through the machine toward and past the side of the turret D1 in the direction of saidarrow a1, and the contour and timed arrangement of said cam 21 will obviously. control and regulate the movements fof said lever 22 and cam bar 24 so as to cause'the latter to be lowered in order that the gripper b may be disengaged from the wire orstrip a' at proper times to terminate the feeding vmovement imparted theretol as may be required during the operation of the machine in the production of needles of various kinds and sizes. The` cam bar 24 being thus permitted to fall by gravity at or prior to the termination of the forward or feeding stroke of the support or carriage Q, permits the. latter to be expeditiously retracted by its spring Q1 after the cam R shall have passed out of operation, the gripper or feeding member Z) being slid rearwardly along the wire or strip a during such retracting movement of the support or carriage Q, so as to standl in position for renewed gripping or clamping engagement with said wire or strip at the next operation of said cams R and 21.

X and `X1 represent, respectively, the channeling meansand eye piercing means which, in the structure herein set forth, are positioned forxsuccessive operation upon the metal wire o'r strip a between'the straightener P and the feeding member or gripper b and within the space separating the respective cam shafts I and N, the arran ement of the parts being such that the gripper operates when actuated, to feed or` draw the wire or strip intermittently past the said 'channeling and eye piercing means so that the successive operations of these respect-ive means are permitted to be recurrently performed upon the wire or strip at such suitable intervals in the length thereof as may be desirable considering the sizes or lengths of the needles to be produced.

The channeling means X is located adjacent to the straightener P so as to be adapted to operate upon the wire or strip for the production of channels or thread grooves at intervals along the length thereof'prior to the operation of the`eye piercing means X1 jthereon, by which yarrangement it will be obvious that the wire or strip is thinned and weakenedat the points wherea-t the eyes are to be pierced prior to the piercing of such eyes, so that this latter piercing operation may be the more readily performed by the applicationv of only such moderate force requisite for the penetration of such thinned or weakened parts offthey wire or strip. 'f

As shown in Figs. 1,15 and 13,.thechan neling means includes two members Z and Z1, between which the wire or strip a fed through the machine by the Aoperation of `the feeding member or gripper. 5 is passed,

the member Z being adapted to be held in stationary position upon the frame at one side of the path of said wire or strip by means of screws e or the like, and being chambered for the reception of a removable tool carrier S provided with an extension or tongue S2 at its lower part over which the wirel or strip a is adapted to be passed during its feeding movement and wherewith said wire or strip is adapted to rest in molding contact during the operation of the channeling means as will be hereinafter explained. The upper part of the holder S is provided with a clamping jaw S1 controlled by a'screw d and serving to clamp or grip a tool or matrix removably to said tool holder for operation upon one of the lateral sides of the wire or strip, the structure and arrangement of the parts beine' such that different tools may be applied interchangeably to said tool holder for the formation of different styles or sizes of needles.

The member Z1 of the channeling means is guided for endwise sliding or reciprocatory movement in a horizontal direction toward and from the member Z at the opposite side of the path of the wire or strip a and has its outer end provided with an anti-friction roll Z2 engaged with a cam Y on shaft I as clearly shown in Fig. 1, said cam being so set as to impart endwise move ment to said member Z1 against the'tension ofaa retracting spring Z3 and after each forward feeding impulse imparted to the wire or strip by the feeding member or gripper b coincident with the operation of the cams R and 21 above described.

. The member Z1 at its end adjacent to the wire-or strip a is chambered for the reception of a tool holder T similar to the holder S except that it is unprovided with a tongue or extension for the support of the wire or strip from which the needles are to be formed, an adjustable clamping jaw T1 controlled by a screw d1 as shown in Fi 5, serving to grip and hold atool or matrix 01 removably upon the tool holder T for operation upon the lateral side of the wire or strip a opposite. to the tool or matrix c, and as clearly shown in Fig. 5, said jaw T1 is provided with a tongue or extension T2 which isadapted, when the member Z1 is moved toward the member Z by the operation of said cam Y, to be slid across the upper surface of the wire or strip a so as to rest in molding contact therewith and to hold the wire or strip securely in position' .against shifting movement durin the operathe machine during the feeding movementof said wire or strip, and after the cessation of each forward or feeding movement, these tongues or extensions also operate to maintain such wire or strip inaccurate position to be operated upon by the respective tools or dies c, c1 during their operation in channeling the opposite sides of said wire or strip for the production of thread grooves therein, it being understood that in the structure herein shown, after each feeding impulse imparted to said wire or strip by the reciprocatory feeding member or gripper whereby types, and in the operation of the channeling means as above described, these die or impression surfaces are impressed 1n the opposite sides of-the Wire or strip a in such a manner as to exert a compresslng lnfluence thereon, and it will be understood that since the tongues or extensions S2 and T2 are provided bearing beneath and above the Wire or strip during the impression of said tools or matrices therein, the compressing influence exerted by said tools or matrices will operate to press the upper and lo-wer surfaces of the wire or strip into accurate molding contact with the adjacent surfaces of said tongues or extensions so as to form and mold the upper and lower surfaces of the needle head, the inclosure of the wire or,

strip around itsA entire circumference between said tongues or extensions and the respective matrices or tools 0, c1 permitting the molding or forming of the entire circumference of the needle head coincident-ly with the formation of the thread groovesand preventing the formation of beards or projections such as have been unavoidably produced during the manufacture of nee dles by other mechanisms heretofore in use and which have heretofore required the subjection of the product to special operations for their removal before the completion of the finished needles. l

The. means above described are particularly well adapted for use in the production of the thread groovesl where needles of large4 sizes are being manufactured, but in the manufacture-of small or fine needles, 1t 1s sometimes preferable to vary the channelingy means as illustrated in Fig. 6, whereinthe.

tongue or extension T2 is omitted from the jaw T1, a plunger or pressure block member U being substitutedl therefor, vcapable of frame and provided with an anti-friction roller 34 engaged withv a cam'V on shaft N, which operates after each forward feeding impulse imparted` to the wire or strip by the vgripper to rock said lever 29 and press the plunger U upon the upper surface yof the wire or strip so as to rest in molding contact therewith during the operation of the tools or matrices c, c1 in producing the thread grooves of the needle. The block or member U when thus operatedin conjunction with the tongue or extension S2 Whereon the wire or strip rests, acts to clamp and hold said wire or strip securely in positionand to prevent shifting movement thereof during the operation of the channeling means.

During the successive revolutions of the shafts I, K and N, bearing cams Y, R, and 2l, thefeeding and channeling means are each recurrently ope-rated in such a manner as tol act alternately upon the Wire or strip a, first to feed the same through the ma chine to such an extent as is requisite for the formation of the desired needle, and then to produce channels or thread grooves in the opposite sides of such wire and simultaneously to mold or form the circumferential surfaces of the needle head adjacent to such thread grooves, and these alternately recurring operations serve to produce thinned or weakened portions at regular intervals along the length of the wire or strip, and the eye piercing means X1 is positioned in the line of feed of the wire or strip a between the channeling means and the feeding member or gripper b, and as shown herein (see Fig. 10) is .distant from the channeling means by the lengths of two unfinished needles, so that two feeding im pulses of the gripper b are required to move each thinned` or weakened portion of the wire lor strip fromthe position in which it stands 'after the operation of the channellng means into position to .be opera-ted upon by the eye piercing means for piercing the eye in line with the thread grooves at the oppo- Site sides of such wire or strip.

The eye piercing. meansX1, as shown in Figs. 17 and 14, includes an'inelosmg member or block f held in stationary position upon the frame and provided with a passage or channel f1 extended through its upper part for the passage and guidance of the Wire or strip a and of such form and dimensions as to conform in the surface contour of its walls, as clearly shown in Fig. 7, to the surface contour imparted by the molding surfaces of the inclosing devices at thechanneling means to those parts of the Wire or strip a which are destined to form the heads of the needles, and the proportion and arrangement of the parts isA such that when the feeding movement- `of the wire under the impulse of the gripper is stopped to permit the operation of the channeling means thereon, another part of such wire or strip previously operated upon and thinned or weakened by the tools or matrices c, c1 and molding surfaces of the channeling means is stopped within the channel f1- of the inclosing member or'block f with its molded surfaces in accurate contact with the conforming surfaces ofthe walls of said passage or channel, 'and its opposite thread grooves in line with a transverse passage L produced in oneside wall of the block or member f and traversed by an endwise movable eye piercing punch z', the extremity j of whichis cut away at topand bottom s as to present an oval or elongated form in cross section conforming to the oval or elongated formation commonly imparted to the eyes of needles, as indicated at a2 in Fig. S.

' The opposite sidewall of the inclosing member or `block f is provided with 'an aperture k in alinement with the passage h through which the shank of the eye pierclng punch is adapted to play, the inner part of this aperture being of a size and form con'- formingy closely to the oval or elongated extremity j'of the punch z', andl` the outer part of said aperture c is made flared or tapered as clearly, shown in Fig. 7, so as to facilitate the discharge ofthe waste material removed from the thin central web separating the thread grooves of the needle when the punch is moved endwise to cause its reduced extremity y' to penetrate such web, as clearly shown in Fig. 7. l In the top of the inclosing member o block f is produced a vertical opening g1 which has communication with the central part 4of lthe passage f1 and is extended in vertical alinement withthe path of the eye piercing punch i, and g represents a plunger or pressure piece or member which is-adapt- I ed to traverse said opening g1 and to bear upon the top surface" of the metal wire or strip in such a manner' as to hold :the same clamped securely within the said assage or the channel f1 so as -toeifective y prevent l shifting movement thereof duringv the o Aeration of the punch inplercing the nee ev eye in the vpreviously .thinned or weakened portion of the wire or strip. In this feeding movement of the wire terminates,

leaving the channeled part'thereof within the passage f1 accurately positioned in` line with the travel of the eye piercing punch z',

in order that4 the needle eye' may be produced againstl endwise' shifting movement while said punch is being operated.

, A punch i' For the actuation of the unch z' I have shown .the machine provided) with an actuating slide or member Z4 guided for endwise reciprocatory movement parallel with the member Z1 and transversely of the path of the wire or strip a through the machine, said member Z1 being chambered at its end adjacent to the block f for the reception of an adjustably mounted chuck Z" in which the shank of the punch z' is vremovably held in suchA a way that it may be replaced or substituted when worn or as may be reuired lfor different sizes or styles of needles.

retracting spring Z6 serves to hold the member Z4 normally drawn out from member fso that the reduced extremity j of the punch is withdrawn from the channel f1, while a cam Y1v on shaft I is engaged with an anti-friction roller on said slide member Z1 and is so timed as to operate after each feeding impulse imparted to the wire or strip a by the feeding gripper b, to force the reduced extremity of the punch endwise through the thinned or weakened portion of the wire or strip within the passage or channel f1 of block f for the production of the needle eye. The plunger g is herein shown mounted upon one end of a lever V2 fulcrumed on the frame and having its opposite end provided with an anti-friction roller V3 engaged with a cam V1 on shaft N, which cam is so timed as to operate after each forward or feeding impulse imparted to the wire or strip a by the operation of the feeding gripper b, but prior to the operation of the `punch actuating cam Y1, to hold said wire or strip securely against movement within the passage or channel f1 of block Vf during the operation of the cam Y1 in forcing the punch carrying slide member Z4t 105 endwise against the tenslon of its retracting spring to pierce the wire or strip for the production of the needle eye. By this arrangement of the parts it will be seen that in the machine constructed according to my invention, as herein set forth, the wire or strip is` accuratelyheld in position while the operated for piercing the needle eye, an deformation of the previously formed molded surfaces of the needle head, or endwise shifting of the wire or strip such as would throw the thread grooves out of registry with the punch are effectively prevented, and by reason o f the wire or strip having been previously thinned or weakened bythe channeling means, so that a comparatively thin web is left remaining between the thread grooves at its opposite sides, it will be understood that comparatively small 1 force applied to the punch vwill 125 lsuilice to pierce the eye so lthat piercing punches of very small size may be successfully employed without undue liability of breakage. In the lstructure herein shown,

f ,the parts are so arranged also that the extremity of the punch i is never entirely withfurther lessen the liability of breakage or damage to the punch.

In order tol facilitate the use of the machine to which my` invention is herein shown embodied, I have provided the channeling and eye piercing means above described with certain adjusting devices which,

as illustrated, include the screws ee Whereby the member X of the channeling means is rendered capable of adjustment parallel with the 'direction of feed of the wire ori strip a' through the machine, together with screws e1 e1 which permit similar adjustment of the members X1 and Z1 of the chan- 1 neling and eye piercing means. As showny in Fig. 7 the block .or member f is also provided with an aperture f2 for the reception of a screw or the like, whereby the same may be held upon the machine frame in adjusted relation to the punch i carried` by the member Z1. The jaws S1 and T1 of the channeling means also afford appropriate adjustment and substitution of the matrices or tools c, c1 while screws e2 e2 at members X1, Z1 also permit convenient adjustment of the chucks 'I and Z5 which carry the matrix c and punch respectively The feeding member or gripper Z) is so positioned as to be adapted for gripping engagement with the wire or strip a at some dist-ance from the forward extremity thereof, and adjacent to saidv extremity of the wire or strip I'provide meansrecurrently operable to sever therefrom lengths or sections suited forthe production of individual needles, and for moving the lengths or sect tions thus severed at angles to the path along which said wire or strip 'a isfed by the operation of said gripper b, so that the said severed .lengths or sections ,may be presented with greater facility and in closer succession to point forming means ca able of operation for the production o the needle pointskwithout lessening the capacity of the machine or otherwise interfering with the free operation of the feeding means.

The turret D1 on the shaft D in the structure herein shown, constitute the meansforv moving the severed lengths or sectionsof the wire or strips at angles to the direction of feed due to the operation' of the gripper b,'

and n represents a disk-like or annular member adjacent to the turret D1 and o f greater diameter than said turret and forming a stop with which the forward extremity *of* the wire or strip a, protrudingI in advance of said gripper Z), is adapted to contact, as indicated in Fig. 17 in such a manner as to assist in terminating and limiting vthe forward or feeding movement imparted to said wire or stripby the operation of the feeding member or gripper b, and to gage the positions in which the severed lengths or f sections are presented to the turret D1,the drawn from the opening h in order to;

needle length positioned adjacent to one.

lateral side of the turret and projecting substantially equal distances beyond the .oppo-y -site faces thereof, and X2 represents the cutting or severing means `whlch is interposed in the path of the wire or strip a between the feeding member or gripper b and said turret D1, as indicated in Figs. l and 17, such cutting or severing means being operable to sever the terminal length of the wire or strip a'after each operatlon o f said feedin member or gripper b so that the severe length suitable'for the production of a finished needle may be received by the turret D1 and thereby carried laterally away from the path. in which the -strip or wire is fed by said gripper across `the pointforming or grinding wheel or drum F1 of the point forming means, as will hereinafter be explained.v i

As shown in the drawings, such cutting or severing means X2 includes knife or cutter members m, m similar to each other and positioned above and below the wire or strip a, asindicated in Figs. 8, 9 and 15, said members being separable to such an extent as will suflice to permit the wire or strip to be passed vfreely between them during the forward jor feeding movement imparted thereto bythe gripper b, and being movable toward each other so as to cut into the upper and lower surfaces of the wire or strip and sever the terminal needle lengths or sectionsfrom such wire or strip after each feeding impulse of the gripper b. These members m, m are also provided, adjacent to their cutting edges with concave molding or die surfaces m1, m1 adapted to meet in registry with each other when the members m m are forced together during the cutting or severing operation in such a manner as to exert such pressure upon the wire or strip adjacent to the point of cut as will impart to its extremity a substantially smooth rounded surface such as is commonly present at the butt end of a finished needle. i

As shown herein, the members m, m are carried upon the ends of levers, o 0 fulcrumed at 35 upon the frame and having their opposite ends extended in position to be engaged by diametrically opposite cam surfaces 36, 36 upon the cam shaft I, a spring 37 serving to retain said levers o, o normally in such position that the members m, m are separated sufliciently for the free passage of the wire or strip a. between them,

and the cam surfaces 36, 36 being so timed cutting engagement with the wire or strip a after. each forward or feeding impulse imparted thereto by the gripper b.

The turret D1 -as herein shown comprises to Abear upon thecentral portions of the several needle lengths or sections a, and hold the'same securely insaid notches or seats D8 during suchrotative movement of the turret'as is requisite to carry .the said lengths or sections longitudinally along the perimetral ygrinding surface of the wheel or drum F1, which latter, as indicated in Figs. 1 and 4, isset with its shaft F at right angles tothe direction of feed impartedto the wire or strip a by the gripper Z2, and is concaved or hollowed out at its central portion of its peripheral grinding surface to conform to the circular path 1n which said lengths or sections va3 are moved during the turning of the turret, so that the points ofI the needle lengths .may be appropriately ground or formed by the rapidly revolving drum orl wheel F1.

Y screw connect-ion with the frame at e1 by v means of which the' band or strip may be drawn lengthwise to cause it to press more or less tightly upon the needle lengths as, as its thin and highly ilexiblecharacter'will permit, so that such needle lengths may be properly held to the turret. Thls accommodates the turret toneedles ofdifferent de p represents a 'resilient memberu or spring j carried upon a cam actuated slide ,member Z8 similar to thel slide members Z1 and Zl above referred to,` and slidable in guides on l 55 the frame transversely to the path of the -wire or 'strip a when fedby the gripper -b through the machine, said member or spring p being s'o spaced from the sidev of the turret D1 past which the terminal length of said'wire or strip is fed-by the gripper b as above :described asto permit said'terminallength'of thev strip or wire, priorrto the.

severing thereof by the operation of the cutting members m, to be inserted by the operatlon of said gripper between said turret and member or spring p, and bein adapted for engagement with said termina length of strip or wire a` when the slide memberv Z8 is moved endwise by the o eration of its cam, so as 'to force the terminal length of said wire or strip into registering notches or seats D8 of the turret at a point immediately above the secured extremity s of the band or strip g.

A retracting sprmg Z1 serves to hold the slide member ZB normally moved in such a direction as will withdraw the spring p from the path of the wire or stri a during the endwise feeding of the latter y gripper b, and an anti-frlction roller 38 on said member Z8 has contact with a cam Y2 on shaft Lnwhich cam is so timed as to impart endwise movement to member Z8 to reciprocate the same O'ainst the tension of spring Z7 after each orward or feeding impulse imparted to the wire or strip a by gripper b, and during the operation of the severing members m, m, whereby the said slide member Z8 is moved suiliciently to cause the member or spring p to press the terminal length of the wire or strip a Within the appropriately positioned notches or seats Ds of the turret. 4

' Each severed length of wire thus engaged in the notches D3 of the turret is held in such engagement by the concurrent operation of the spring p and ca`m Y2 during such turning movement of thefturret as will suffice to move said length of wire downward into engagement with lthe strip or band g and ,out of line with the remaining uncut portion of the wirel or strip a, after which the cam Y2 passing out of operation permits the spring Z7 to retract the slide member Z8 and thereby `to withdraw .the spring p out of the pat-h` of the end of the wire or'strip a when next advanced by the feeding impulse of gripper 6,'and the strip or band g retains the severed lengths of wire securely engaged with the seats or notches D3 ofthe turret during the further turning movement thereof needful to carry said severed length of wire past the point forming means. g

Since the wire or strip a from which the needles are produced is comparatively thin, it will be obvious that a very slight extent of rotatory movement of the turret D1 moving at an angle to the direction of feed yimparted by the ripper b, and occurring after the severing o the terminal length of wire or Y strip by the operation of the severing means rX2, will suliice to carry such severed length out of line with the remaining uncut part of said wire orr strip, 4so that thereafter such severed length will offerno obstacle to the further forwadfeeding movement ofthe upon the vsucceeding feeding wlre or stri Operation o the gripper b, whereby it will be evident that the turret D1 may bel rotated at a comparatively slow speed by means of thereupon for a longer time and to better.

advantage for the pointing of the needles.

During the operation of the .turret in carrying the needle lengths past the grinding wheel or drum F1, the extremities rof the needle lengt-hs are caused to `bear frictionally upon the concaved perimetral grinding surface of said drum F1` so that the points of the needles are accurately formed, the needle lengths being caused to turnupon their axes within thenotches or seats D3 by the conjoint rotatory movement of the turret Dl and said drum or Wheel F1, so as to assure accuratel fashioning of said points, and during the operation of the point forming means, the but-t or head ends of the needles, previously fashioned and rounded by the molding surfaces of the severing members my, m, rest in contact with the stop disk or member n, so that uniformity of length is assured in the finished product.

The direction of rotation of the drum F1 as indicated by the arrow a5 in Fig. 4, is also toward the stop disk or member a at that part of the grinding surface whereon the ends of the severed lengths a3 rest to be pointed, whereby it will be .seen that themovement. of the drum or wheelF1 i's utilized to retain the'lengths of wire with their butt ends accurately contacting with said disk or member n to prevent variation in the length of the finished product.

The point grinding drum or wheel. F1 has its shaft F mounted in bearings in the ends of arms F2 forwardly directed from a bracket F3 adjustably held upon the frame by means of a bolt and slot connection, as clearly sho-wn at Ft in Fig. 4, of the drawings, so as to permit convenient adjustment of said Wheel or drum F1 toward or from the limiting sto-p or member n, whereby it will be seen that the parts may be readily accommodated for use in connection with needles of different lengths or of differentdegrees of neness.

At the side of the turret D1 opposite to the spring p is-positioned a receptacle 0 having an/aperture at its lower part whereat the pointed needles are received from the turret after passing the point forming means, the band or strip g being outwardly directed from the side of the turret adjacent to said aperture of the receptacle, so that the finished needles are released from the turret to permit their delivery in said receptacle. A pendent tongue 02 at the side of the receptacle adjacent to the turret and extended near the spaced disks D2 thereof as indicated in Fig. 16, operates to withdraw the completedv needles from the notches or seats of the turret and prevents said needles from being lifted out of the receptacle by the rotation of the' turret.

The invention presents many important advantages and improved results in its practical use in the manufacture of needles, permittlng them to be produced in a substan- --tially continuous operation, which 'may,

when desired, embody the invention set forth in the United States Letters Patent, No. 963,987, granted to me July 12, 1910, and dispensing to a great extent with handling of the product and various other manual operations which havehitherto been requiredin this art and which have greatly increased the costof the nshed article;

The needle making machine embodying my invention is of an extremelyvsimple and compact nature and is comparatively inexpensive and economical in construction and operation and presents other important advantages by reason of the facility with which its operative parts may be adjusted to meet the requirementsl of different sizes and styles of needles to be manufactured, and `of the novel and improved manner in which the several operative parts co-act with each other and operate recurrently upon the metal wire or strip for the successive production of the needles therefrom. The employment of the holding means, including, in the embodiment herein illustrated, lthe tongues T? S2 at the channeling means, and the member g at the eye piercing 10o means, also presents import-ant advantages, since such holding means, like the channeling and eye piercing means in connection Wherewith said holding means is used,` is caused to act upon the wire or strip alter nately with the operation of the feeding member b thereon, so as to operate effectively to prevent retraction of said wire or strip from its advanced position during the retracting movement of the feeding member 11o which occurs while the strip or wire is held by such holding means.

The machine as herein set forthlis especially weil adapted for use in the manufacture of ordinary sewing needles but it will 115 jbe understood that my present invention isnotlimited in its' scope to its embodiment in or application to machines for the manufacture of needles of any particular style o r type but may be applied with equally', 12o good resultsto machines for making various other kinds o-r styles of need-les, such as those employed in mechanical knitting and embroidering, for example, forv which purposes, the various operative parts of the 125 4machine may be modified as may be deemed necessary or desirable, within the scope of the appended claims. For example, in the manufacture of embroidering needles such as are above referred to and which, as rep- 13o at opposite sides of the turret D1 for grinding the opposite ends of the severed needle Y lengths vfor the production of the oppositely arranged needle points. i
