Applination fi lefi llune 7, 1911. :SErielNa-SMBM.

vide a simple andeffective mechanism for straightening light bars or Wires, and particnlarly sewing machine needles, and the following description relates more particularly 'to the. tnuing of sewing machine nee dies-subsequent to the tempering operation.

In its preferred form, :the improvement comprlses a plurality of separated rigid sup- .pQlts one of WlllCh' is movable toward and 20f tive face with a needle-shank recess or from the other and is provided in its opera- .pocket serving as a hearing, within which the shank of the needle is revoluhly heldby a spring-pressed rotator applying a substantially invariable yielding and resilient pressure thereon to maintain the needleblade spaced slightly above the face or operative "edge. of the stationary support or anvil. A straightener in the form of a rapidly reciprocating hammer operates upon the needle-blade between said supports and constantly close to the stationary support. Theposition of the needle in being straightened is thus gaged by the contact of its rotating shank upon the walls of its recess and the needle is sustained similarly to the manner in which it is held in the needle-clamp of a sewing machine, While the straightening. operation is performed progressively upon the needle-blade from the shank to the eye by aseries of regulated impacts of the hammer proportionate to the eccentricity of the needle relative to the axis of its shank.

.A stationary needle-hopper is mounted at one :side of the movable needle-supportwith its hottom at substantially the same level therewith, and needles are successively conveved from the hopper to said support by an inserter comprising a reciprocatory slideplate affording a bottom for the hopper and provi led with a needle-cavity registering alternately vvith the interior of the hopper and with a needle-shank receiving recess or pocket formed in the upper face of the needle-support. The needle-com'eymg slideherein termed a striker, between which great plate has pivotally connected with its outer portionan ejector consisting of a pair of fingers adapted to engage a-needle within the needle-recess to remove a straightened needle therefrom, simultaneously with the conveyance thereto of an unstraightened needle from {the hopper.

The-action of the-hamn1er is governed by an lmpact-regulator which is preferably controlled in its operation by a feeler con-- tacting with and partaking of the eccentric movements of the needle at the bend or eccentric portion close to the stationary support or anvil and upon the side thereof opposite the hammer. To this end, the hammer has rigidly connected to it, so as to partakeof its reciprocatory movements a movable stop-member which is for convenience and a fixed abutment or thrust-block is interposed a transversely movable space-block preferably in the form of a .vedge and sustained by a vibratory arm fixed to a roclzshaft to which is rigidly secured a feelerarm formed of relatively yielding members each carrying one of the component sections of the needle-engaging die. The vibratory increments of the fee1erarm derivedfrom the rotation of the bent needle-blade or other article to be straightened are communicated to the space-block aifor ding the active member of the impact-regula tor and Whose position intermediate the striker and the station ary abutment determines the point at which the operative movements of the hammer are arrested corresponding in extent with the degree of deflection or eccentricity of the needle or other article.

It has been found in practice in the tempering of needles that the distortion due to successive heating and rapid cooling is t at the points where differences in thickness occur, viz.. at the junction of the blade with the shank and at the eye, While in. the intermediate portion the distortion is comparatively slight. Owing to the small amount of deflection of needles having even the maximum degree of distortion received under actual-working conditions, and the extremely small power possessed by thenee- Patentedil'an. 19, 1915.

without materially increasing the complex ity of the mechanism, to time the hammen blows so that they shall be delivered invariably .in exact register with the extreme point of deflection of the needle. Accordingly, instead. of adjusting the machine to deliver oneor more straightening blowsin exact register with the bend or crook to be removed, at or intermediate the extremities oi the blade during the rotation of the nee die, the mechanism is constructed to produce in each cycle a, cornparatimly large number of relatively light blows in quick succession, the period of action of the hammer and the lengthwise feed of the needle being so timed that a primary series oi? regulated blows delivered upon the blade adjacent the shank while the needle continues to rotate, so that a suflicient number of impacts is delivered in such portion of the nee dle to perform the straightening action cumulatively. A further series of blows is distributed along and around the biadc in such manner as to remove any deflection therein intermediate the shank and a point near the eye, at which point the feed of the needle is. again arrested for delivery-0f a final series of concentrated regulated blows around the circumference of the needleblade adjacent the eye, preferably somewhat greater in number than the primary series bf blows with an effect at such point similar to that previouslyproduced adjacent the shank.

The present improvement will be more fully understood by reference to the ac companying drawings, in which Figure 1 is a sectional elevation of the needlestraightening machine, and.

The machine 18 constructed with a frame.

comprising the base-plate 1 to which are so cured by means of screws 2 the feet 3 of the end standards a which support the bed 5 sustaining the various operative parts of Secured to the lower side of the bed 5 are the bearings (i in.which is jo'urnaled the cam-shaft 7 having fixed thereon the worm-wheel 8 meshing with the worm 9 secured upon the transverse mainshai't 10 mounted in bearings 11. secured upon; the base-plate 1. Loosely mounted upon the main-shaft is the hub 12 of the grooved belt-whcel 13 which is encircled by a belt 1% from the source of power for ro tating the main-shaft.

The rearward end of the hub 12 is formed with a projecting clutch-tooth 1 5 adapted for engagement with the similar clutchtooth 16 upon the adjacent face of the grooved belt-wheell'i whose hub 18 is fixed upon the main-shaft, and which is embraced by a belt 19 running over the grooved beltwheel 20 fixed upon the transverse hammeractuating shaft 21 journaled in the spaced bearing standards 22 extending upwardly from one end of the bed 5. The forward end of the hub 12 of the driving belt-wheel 13 is formed with an annular groove 23 entered by the flattened head 2-1 of the shiftlever 25 pivotally mounted by means of the stud-screw 26 upon the post 27 rising from the base-plate l and atlording a means of shifting the pulley 13 endwisc of the driving shaft for eii'ecting the engagement and disengagement of the cl utchmembers 15 and'lli so as to connect and disconnect the machine and its source of power at the will of the operator.

The hammer-actuating shaft 21 has fixed thereon the l1ub'28 of the camovheel 0r trip 29 formed withaseries of peripheral teeth 30 having inclined outer faces to effect a wiping engagement with the concavely curved adjacent edge of the arm 31 having a split hub 32 rigidljrsecured by means of the clamp-screw 33 upon the hammer rockshaft 34 journaled in the bearing standards 22 parallel with the actuating shaft 21, said hub projecting laterally therefrom tension spring '38 Whose lower end is atopposite the arm 31 a second arm 85 formed in its upper side with the spaced notches 36 torecelve-the loop 37 at the upper end of a tache'd to a staple 39 upon the bed 5. The spring 38 serves to yieldingly maintain the arm 31 in operative relation with the hammer-retractingcam-wheel 29 and to impart to the hammer a peening impact. Assho'wn in detail in Fig. 6, the hammer rock-shaft 34 has formed integral therewith the block 40 havingfa lateral wing ll to afford a striking shoulder 42, to be later referred to, and a forward extension 43.

The split hub 4.4 of the'hammer-helve .45

is formed with the spaced ears 4L6 drawn together by means of the screw 47 to-clamp the same upon the hammer-shaft 34, and the to by means of the screw 00 passing through the part 43 and tapped into the helve, an

adjusting screw 51 being tapped through the extension l3 and its point resting upon thetop ofthe helve. Bymanipulation of the screws 17, 50 and 51 .in a well known manner the position of the hammer-head relative to its shaft 3% may be adjusted.

Adjacent the path of reciprocatory movement of the hammer is disposed the anvil or blade-support formed with a wedgeshaped blunt upper extremityand provided at the lower end with a flange 5i having tapped through it the adjusting screw whose point rests upon the top of the bed l'he anvil 52 is fitted within a chan nel in the bearing block 56 in which it is secured by means of the clamp-screw b7 passing through a slot 58 in the bearing block and tapped into the anvil.

In order to permit the intrmfluction and removal of needles in the pocket 76, provision is made fortemporarily retracting the trictionu'hecl 82 in opposition to its spring.

The-slide-plate 117 is formed at its rearpurpose presently to be deward end yith the spaced bosses with an intermediate slot 12 within which is supported npon the pivotal pin 125 the roller 126 WhlChylS embraced by the fork 127 at the upper end of one arm 128 of an anglelever mounted upon the fulcrum screw-stud 12-9v sustained by the forked bearing block 130' upon the base-plate 1, said angle-lever having a second arm 131 carrying a rollerstud 132 maintained in engagement with the periphery of a cam-wheel 133 fixed upon the camshaft 7 The cam-wheel 133 has in -its periphery a substantially V-shaped recess 131 extending inwardly nearly to its supporting shaft 7 and a series of indentations 135st another part of the circumference, the roller-stud 132 being caused to follow the contour of the cam by means of the spring 136 connected at one end wit-ha pin 137 upon the lever-arm 12S and at the other, end to a fixed pin 188 depending from the bottom of the bed The rocking 1110-.8-

, ments'imparted to the angle-lever by means downwardly to the upper face of the slideplate 117 which has at its forward end a latral extension 117 moving in a slot 141 of, one .of the side-plates 141.

The slidefplate-thus affords a movable bottom for the hopper and in its full-stroke reciprocatory movements serves to carry laterally from the hopper needles dropping successively into the slot 121 forwardly over the platform 115, and into the needlepocket 76 of the 'needlesu'pport whose upper face is at the same level and continuous wlth said platform." c

The short'jogging movements ofthe slideplate or neecllecarriea 1.17 p

near its retracted position with the needlev are performed slot or cavity- 121 intermediate the lower edges of the end plates 142 of the hopper, and these jogging movements serve to agitate the needles and separate from the mass of needles indi idual needlesfor introductlon therein for conveyance to the needlesupport The unstraightened needles are he quently so bent or distorted by the'hardening or temperingoperation as to occupy a width of space materially greater than the diameter of their shanks, and their blades often become more or less interlocked, in

consequence. In order that they may bereceiving end of the slot 121, the needle entering the slot has itsblade upwardly in clined so that the shank first enters the slot and the blade is enabl'ed to disengage itself from those of t 1e ad acent needles, thereby preventing the clogging of the carrier in conveying the needlesindividually from the hopper.

Extending upwardl and forwardly from the forward extremity of the slide-plate 11-7 are the spaced perforated lugs 143 upon which-is pivotally mounted by means of the pins 1.1-1 the needle-ejector 145 having the forked eiector-fingers 146 and H'Z-to the latter of which is applied the spring 1 18 for pressing the same downwardly. The lower edges of the fingers 146 and 147 normally. rest izpon the unnerface -,of the. platform 115 when the slide-plate 117 is retracted, but in the advance of theslide-plate these tingers ride downwardly through the notches 1&9 and 150 in the forward edge of the platform, the finger 1418 traversing the runway 79 extending transversely of the butt ends of the needle-shank as represented in Fig. 10.

Upon the delivery side of the needle-sup port and flush with the top of the same is :1 extension thereof 151 formed with a badvvardly projecting needlesupporting finger 152 and with a transverse depression 153, the extension member having foot-piece 154.- secured by means of a screw 155 upon the top of the carriage 65. The inclined upper face of the body 14-5 of the e ector has secured thereon by means of the screw 156 a needle-retaining spring 157 extending for; wardly intermediate the fingers 146 and 14. and so shaped at its outer end as to lightly press the. needle upon the top of theneedleably connected with the head 159 support 74. the finger 152 and extension 151 thereby producing suflicient resistance to the advance of the needle to confine it within the forked operative ends of theejecting lingers so as to positively control. the move ment of the needle. As the ejector reachesextreme advance positionundcr the action of the slide-plate 11.7 in conveying a needle from the hoppor'to the needle-shank pocket 76 the straightened needle engaged'by the ejecting fingers drops into the depression 153 and out of the range of action of the retaining spring gravity into the delivery chutefor conveyance into the receiving tray or receptacle.

As herein shown, the end plates 1 12 of the hopper are formed with the vertical slots 1 12 to receive the pressure bar 158 detachof a ver' tical bar 160 suitably journaled in'the bed extension 5* and in practice carr 'ing a weight by means of which a pressure is placed upon the shanks of the needles in the chute so as to maintain the needles in sub stantially parallel relation to insure their proper delivery, to the carrienplate 1.17.

Secured upon the bed 5 adjacent one of the bearing standards by means ()Zii'SQi'QWS 161. is the foot 162 of an abutment plate 163 formed with an inclined. and circularly curred Sllllllldfjl 164i toward and from which the shoulder 41-2 of the striker {11 moves upon the shaft 341 during the operation of the hammer. Intermediate the shoulders 42 and 16a is interposed the wedge-shaped spacehlock 165 constituting the active member of the impactregulator and which is sustained by. means of. an elastic stem 166 bent transversely-from the outer endof'a vibratory lever 167 Whose opposite end is formed with a round shank 168 fitted to a transverse aperture"1( 5 9 in the collar 170 formed integral with the feeler 'roclt-shaft 171 having at its opposite ends the axial pins 172 j'ournaled in central apertures in the bushings 173 secured.

by'means of set-screws 174i in'the spaced standards 175 of a controller-bracket 176 having a foot 177 provided with elongated transverse apertures 178 entered by the shanks of the fastening screws 179 by means of which said-bracket is ad ustably secured upon the bed 5. The shank 168 of the lever 167 is secured adjustably Within the aperture 169 by means of the set-screw 180.

. Any suitable means may be employed for connecting the wedge-block 165 resiliently with the vibratory lever 167, but it is important that such connection be suliiciently rigid to sustain th wedge-block in its moyomcnts along cthe grace of so as to avoid an I such movement. As shown niorc particu- Figs. 1 and 12 the inner face of the 165 is substantially concentric space-block I and the ad awith the controller shaft 171,

157, and thus rolls by 189 therein.

. at the side oi? the the abutment 164 frictional resistance to cent face of the abutment is similarly curved so as to enable the space block to move as closely as possible thereto without actually touching it in its movement under the influence of the lever 167. I

The rock-shaft 171 has secured thereon. by means oi the setscrew 181 a block 182 in which is secured. a laterally vbcxitradially extending arm 183 carrying the counterweight 184.- secured adjustab y thereon by means of the set-screw 185. be offset portion oil. the arm 183 is embraced. between two spaced stop-lugs 186 formed upon an angleplate 187 adjustably secured upon one of the standards 17 5 of the lccler-bracliet by means of a screw 188 whose shank enters a slot By meansot the weighted arm 183 just described, the lever 167 and the space-block 165 are counter-balanced upon "the supporting ll'FClPSllflll) 171, while the stop-lugs 186 posltivclylin it the range of movement of the space-block and insure against orcrtln'ow under abnormal conditions of control in'rpartcd by the action of the hammer upon the needle.

b er i by means of the setazcrew 1%)!) upon c rock-shaft. 17.1 intermediate the collar 170 and llloclr. 182 is a forked block 191 to the opp to faces of which are socured by means at serous 192 and 198 the elastic shanks 191 of two relatively yielding springarms .195 extending lengthwise of the needle and the directim'i of movement of the carriage and having at their outer ends the alincd h nges 196. Each oi these flanges is fitted to and secured by means of a astening screw 197 within a channel formed in the back of one of the component sections 198 and 5.99 o'f'a die constituting the color co11tact-me1nbcr and whose relatively tongued and. recessed adjacent portions are formed with the substantially round needlerccciring aperture 300 which. is outwardtv flared to form a conical month 201 in the outer face. The springarins 19.7mm sulliciently thin to yield in unis in. laterally so as to follow the-circular inovi'aucnts of the unstraightcned needle entering the die, while the elasticity of their shanks 191 permits the separation of the (l'l-f5fl()i3lflll$ i'iormally held together thereby and thus adapts them to accommralate a nrcdle-blarlc of larger than normal size to proride for emergency by accililcnt associated in the same charge ol' the hopper.

As will be evident by rl-yferencc to the drawings. the lceler preferably arranged anvil. or stationary needle- ;aipport opposite the path of inovcmcntcf theha nmer and its component members are adaptedto contact with the opposite sides of the needle-blade close to the anvil, with the upper member thereof engaging the same side 01 the needle-blade: as the hammer.

In order to provide for the adjustment of the spring arms 195 toward and from each other, the block 191 is shown in Fig. 15 vvith the portions of its opposite 'faces adj cent the screws 193 slightly convergent, that by turning these screws in, one or the other direction the distance between the arms may be varied. The screw-apertures in the flanges 196 to accommodate the screws 197 are made of elongated form so as to permit the adjustment of the die-sections upon their respective carrying arms to'coinpensate for wear resulting from long continued use; By removing the screws 19? thevdie-sections may obviously be remm ed for replacement by others fitted to a di'ii'ercnt size oi? needle.

In practice, the needle-holding and straightening members may be properly set for effective operation by first inserting a perfectly straight needle in the holding support 7% and advancing the carriage to bring the needle-blade above the anvil; then adjusting the top or operative edge of the anvil a few thousandths of an inch below the lower side of the needle-blade, and finally setting the hammer upon its rockshaft 34; by meansof the adjusting screws 50 and '51 to bring the point or nose of the hammer-head just into contact relation with the top of theneedle-blade. When the ham- 'mer is at rest in its extreme lower position,

it is thus set at a point slightly more re moved from the plane. of the face of the anvil than the diameter of the needle-blade.

The hammer is su'ccessiveh li 'ted and re leased by engagement of the arm 31 with the per-i i the lian'inier-head being lifed to the same point in each retract-ire movement and performing its operative stroke under the influence of its own weight augmented by the action of thespring 38 until forciblv arrested by en inent of its striker with the a e space-block interposed between the same and the fixed abutment or thrust-block 163. The; gyratorv movements of the unstra: ht-

'ened needle passing through the die over and adjacent the anvil impart to the feelerarfm vibratorv movements winch are communicated to" the le er lGTtransmitting to the V move' nts. The position of the spacesit on of the shou in..-

ce-block its operative reciprocatory block obvi ousl determines the Stfi}')])lng polder l? of the striker relative to the fixed shoulder 16% and thus determines the extent of the effective stroke, and hence the effectiveness of the blow struck bv the-hammer. As the determination 05. ammerstroke is by this means delayed until actuallv the instant that the blow delivered to the needle, and as the control of its stroke is regulated bv the deflection of the need e from its axis at the same instant andcupon the diameter of the.

teeth of the tripping cam 29,

needle 'parallel'with the direction of move mentor the hammer, it will be seen that without interrupting the uniform rotation v enables it to act asxa recoil absorber .which accommodates in the feeler itself the abnormally rapid changes in the deflection of the needle produced bythc impact of the hammer thereonand prevents their being transmitted to anvconsiderable extent to and causing the excessive overthrow of the active member'165 or of the impact regulator. By emplovment of the stop-members 186 the lever 18? is prevented from performing such abnormal movement, and the control. of the space-block is not therefore -materiallv impaired by the blow of the hammer upon the needle undergoing-the straightening operation.

Suitably secured upon the bed 5 is the inclined chute extending forwardly f om the needle support extension 151 and provided with the side flanges 203 .to which are pivoted by means ofthe transverse pins 20% the depending ears 2'05 of the swinging gate 206 formed with the needle-detaining lip ZOY'normallv resting upon the bottom of the chute and serving as a barrier to arrest the straightened needles as thev are deli ered from the needle-suuport 906 has a fo wardlv extending arm 208 with a downwardlv and laterallv inclined finger i zfltl no mallv deuendingbelow the extens on-plate 151 but adapted to be engaged by the same in the travel of the carriage to present a needle for the stra ghtening open atioxn thereby causing the l fting of the gate and raising of the lip 207 to permit the straightened needle previously detained t'lierebv to continue its mo ement through the chute and into the holding receptacle The gate 210 .which is pro ided on the adjacent side with the hooked lugs Q11 engaging the upper edge of a plate 212 suitablv secured to the front edge of the bed The obiect in arresting the movement of the needles be t een their release from the eiector and arrival in the rcce'utacle 910 is to insure theirsi bstantial uniform delivcrv within the a 1g receptacle. As the shanks are conidcrahlv larger and heavier than the blades.

the teuoeucv is for the needles to assume various directions in moving any considerable a as i with the portions 69 69 .60 tion of an unstraightened needle :tance through the chute if the latter is pro gided with means of control such as e herein shown and described. While the needles are being introduced removed from the needle-support and lc they are being advanced across the. anvil and through the icelcr-die to present *ally for the straightening action the ,ofthe blade joining the shank, it is periphery of lifting cam fixed upon the -21 Uri: aft 7. This cam is formed in two 1-. tions E HT and 5218 arranged side by side and. formed with substantially circular peripheries with proiections 219 and 220, "respectively, forming operative portions. The hub 221 of the primary section 217 is secured adiustably upon the camshaft by at; means of the set-scrcw 2:22, and the hub 223 of the auxiliary section is lit-ted upon the hub 221 of the primary section and secured for circular,adjustment thereon by means of the set-screw 224. By shitting one of thesesections upon the other, the efi'ective length of theoperatiye face of the com jY- PI'OSlt B cam thus formed. may be lengthened -01" shortened to produce the requisite period of inaction of the hammer-, Which is determined by the length of the needle-blade be- ;t w'een the eye and the shank.

As'representeddiagrammatically in Fig. 17; the projections 219 and 220 of the sectional cam 217 218 are arranged in register and (39 oi: the feedcam groove 69 in order that the action ot the hammer may be interrupted While the rotator 82' is arrested or the release of a straightened. needle and subsequent inserand wnile the carriage is moving bachwardly from the final straightening position and advancing to extreme initial straightening position rel ative to the anvil. T he projections 261.5 and 220 are obviously adjusted relatively to the .cam shaft'i' andto each other in such mannor as to determine the period of action and timing of operation of the hammer to pro 'uc'e the desired number of impacts upon iihe needle during the initial and final dwells of the same, the number of blows adjacent the needleeye being preferably somewhat greater-than near the shank;

In order to provide for needles of differ cent side-plate 'megnbers, is retracted,

lower extremity separate ent lengthirom point to butt end of shank,

an adjustable lining plate 225 is applied to one side of the necdle-hopper-and is formed with an outwardly projecting stud 2'26 passing through a bearing boss olf the :idja 141 and secured adjustably therein by means of the set-screw In the initial pr ms of the operative parts of the mcclumism v the carriage, which sustains the movable neeclle-s:.1pport 74- constituting' one of the needle-shank gripping the needle-carrying slide -plate is withdrawn to position. its needle'cavity beneath thelower end oi. the hopper, the other gripping member, consisting of the frictioirwheel or rotator, is raised, and the hammer retained in elevated position by engagement of the JOYPlJtll Elli with the helve all. as ici'ntscntml in l! 1, 2, 3 and 4t. The actuation of the shiftlGYQl 25 to throw the clutclrhub of: the continuously rotating pulley '13 into operative relation with the clutch-member of the fixed belt-pulley 17 causes the rotation of the main-shaft 10, the hammer-actuating shaft 21 and cam-shaft 7. v

,The needlc-inserter or carrier 117 now makes afull stroke which c: an unstraigbtened needle n a Wi hlll its cavity 121 forwardly over the platform ill!) toward the needle-support and simultancously carries the ejecting lingers 148 and i l-7 to, between and beyond the separated needleshank gripping members, thus causing them to forcibly engage the blade 11 and shank 01', respectively, oi the previously straightened needle resting in the groove or pocket 76. Asthe carrier completes its advance or operative movement, the shank oi": the unstraightenednecdle is caused to drop into the pocket 76 with the adjacent portion of its blade resting upon the supporting or steadying finger 152 ot' the extension 15,1. The needlecarrier now retires and the rotating frictionwheel 82 descends into frictional engagement with the needle shanlr and rotates it while detained from lateral movement by engagement of thelnclined side-Wall of its pocket. After the needle-carrier has returned to retracted initial g'iosition, the qagcment oi the 1ol.le"stud 1.333 with the plua'al cavitics i735 oi the can i is 'a slight jogging: n 'eruen i v .n. the mass at unstraightcned a single i'icczl'lr-zul'iich l2l prepa 'atory to a needles in toe hopper drops into the slot :uicceed The carriage now ma a quiclr movement to extreme advance position under the action oi the feed-cam so as to bring that portion of the needle-blade a(l 'acent the shank close to the anvil and within the path of the lllIIlll11',lll1 point of the needle entering the feelc l.ie aperture 200. The stop-bar 214 then descends to release the hammer-helve and the hammer begins its operative recipro-z Ill - l trans 'er stroke or the carrier.

sitionbf. the hammer is formed eccentri-- and 20 wherein the block l0 fixed to the hammer rock-shaft 3% is formed with a lateral wing 41 having a curved lower operative edge l? which, in the striking phcally to a fulcnum-pin mounted in fixed bearings 230. mounted thereon the hub 281 of an angleleverlhaving an upwardly extending arm 232 whoseupp'er end is adapted to atl'ord a stop for engagement with the operative face d2 of the wing 41, while a laterally extending arm of said lever isformed with a rounded extremity 234 entering a socket in the laterally extending lever 36 whose shank 237 is secured within the ransverse aperture of the collar ,170 of the feeler'rock-shaft 171 by means of the set-screw 180. I

In this modification ofthe improvement, the feeler rock-shaft is oscillated by engagement of the feeler-arm with the needle as in that previously described, and the consequent vibrations of the lever are communicated to the stop armfl32 of the vibratory angle-lever to bring the point of the same at varying distances from the hammer rock-shaft 3, whereby the efiective stroke of the hammer is controlled in a manner similar to that previously described.

In this construction it will be observed that the member-232 is the equivalent of the space-blockltlfi,while the fulcrum-pin 2-29 receives the thrust of the striking member f notion of the thrust-block 163.

The inclination of the axis ofrotation of t 1e friction-wheel 82 relative to the needlere'cess 76 has a tendency to produce both circular and endwise movementsof the needle, the end ise thrust serving to mamtain the butt end of the vneedle-shank firmly pressed against the stop-plate 81 so as to maintainfthe needle in fixed position upon its traveling'support, but it is obvious that this inclination of the needle-rotating means might readily be employed, by omission of the stop-plate, in producing the endwise feeding movements of the needle upon a stationarysupport without departure fromthe scope of the present invention. The needle-shank recessis for convenience made I in the formof a groove corresponding sub stantially in diameter with the needle-shank,

- but it.:is evident that any suitable means may be provided iupon the needle-support for detaining the ireedle-shank from lateral movement under the upper face of the The fulcrum-pin 22-9 has action of the friction wheel, the function of the depression in the needle support being merely to maintain the needle in position thereon during the straightening operation: in operation the needle-shank is held resrllently upon its traveling support by the yielding-faced rotating member 82 to enable the needle to accommodate itself 'to the peening action produced by the impact of the hammer intermediate the relatively movable supports, while the blow is directed upon the needle-blade intermediate such ri 'id supports. The relation of the cams 69 and upon the needle-blade are concentrated around tile latter adjacent both the shank and the eye, at the beginning and conclusion oi ments of the needle beneath the hammer.

The cylindrical surface of the needleshank has a bearing edirectly upon its support with the blade disposed very slightly above the operative edge of the anvil and rotates in contact with the walls of the cavity in its support during the straightening operation so that the blade is gaged or centered with precision under the action'of the hammer relative to the-shank,

and the needle is thus held-during thestraightening operation in precisely the same'way in which it is ultimately secured in the needle-clamp of a sewing machine for cooperation with a loop-taker in performing the stitcl7.forming operations' As the controller or feeler is very-accurately counterbalanced so as to impose sub stantially no resistance to the controlling action of the needle which it embraces, it

constitutes."practically a floating member capable of following with great freedom and precision all movements of the needle transversely of the latters axis such as or imparted by bends or 'eccentricities therein. It is also free to move laterally in a horizontal plane. As the feeler and impact-regulator are mounted upon a unitary support, shown herein consisting of the rock-shaft 171, it is evident that they are caused to move in unison, so that the movements of one are transmitted accurately to the other 2-17 issuch, however, that the blows of the hammer the endwise feeding move From the toregoi be seen that the. in volves principles rangement of the susceptible ofemb ent forms and Z )c itions of parts, that thepresent intention is not therefore limited to the details of construction and arrangement shown and described herein.
