In the drawings, 10 represents the bedframe of the machine, to which are secured the supportirig-standard 11 and the swaginghead 12, provided with the three rotary swaging-

spindles

13, 14, and 15, (see Fig. 3,) which are actuated for revolution by means of suitable pulleys 16, which pulleys are not shown in said Fig. 3, but are shown in other figures of the drawings. At the top of the swaginghead 12 is attached the frame-piece 17, which holds the wire-feeding mechanism, as shown in Fig. 5 and also shown enlarged in Fig. 10, the said frame-piece being provided with a slot 18, the sides of which form guideways 19 19 for the reciprocating cross-head 20, which carries the clamping-jaws that serve to bring forward the feed-wire 21 from the coil, the said wire passing first through the stationary guide-tube 22, thence through the opening 23 in the reciprocating cross-head, and thence between the clamping spring-jaws 24 of the tube 25, the said clamping-jaws being actuated to close upon the wire by means of the lever 26, pivoted to the cross-head on the pin 27, the said lever being forked at its upper end and provided with the adjusting-screws 28 28, which bear against the opposite sides of the cross-bar 29 of the lever 30, formed of the connected parallel arms 31 31, which lever is pivoted at its upper end to the top of the bracket 32 and is yieldingly connected at its lower end to the sliding head 33 by means of the cross-piece 39, (shown separately in top view in Fig. 14,) to the ends 34 34 of which the lever 30 is jointed, the oppositelyprojecting cylindrical arms 35 35 beingloosely held in the cylindrical chambers 36 36 at opposite sides of the transverse notch 37, and at the ends of the cylindrical arms 35 35 are placed the spiral springs 38 38, by means of which the yielding engagement of the lever 30 with the sliding head 33 is effected. The wire is forced by means of the clamping-jaws 24 of the feeding-carrier through the passage 40 and between the clamping-jaws 41, (see Fig. 23,) the said jaws being actuated to clam p the feed-wire 21 with a yielding pressure by means of the pressure-shoe 42, the upper portion of which is of smaller diameter than the lower portion, thus forming a shoulder 43, against which the spiral spring 44, which is held upon the upper portion of the pressureshoe, is caused to bear, and upon the upper end of the said pressure-shoe is placed the loose cap 45, the said cap being made to rest upon the upper end of the said spring 44, so that the downward movement of the cap, by means of the lever 46, will serve to impart a yielding pressure upon the wire held between the clamping-jaws. The lever 46 is actuated by means of the wiper-cam 47, in connection with the downwardly-curved end of the said to the rock-shaft 48, which shaft is actuated by means of the toothed arm 4!) (see Figs. 15,

16, and and the upright sliding bar 50, provided at its upper end with the rack-teeth 51 and bearing at its lower end upon the edge cam 52, held to turn loosely upon the fixed stud 53, the said sliding bar being held against the said cam by means of the spring 54. (Shown in Fig. The feed-wireis fed forward through the stationary cutting-die 55 and through the movable cutting-die 56, held in the sliding head 5'7, the downward movement of which serves to cut the needleblank from the wire and transfer it to a position for engagement with thejaws of the sliding spindles of the carrier. When the wire 21 has been fed forward by the action of the feeding-clamp and then held by the stationary clamping-jaws 41, the milling-tool 59 of the sliding rotary spindle 60 (see Figs. 15, 16, and 17) is brought forward to true up the forward end of the feed-wire, whichserves to form the rear end of the needle-blank. The

said sliding rotary spindle 60 is held in the horizontal spindle-holding arm (31, pivoted upon the fixed bracket- (32, the said armbeing clamped to the said bracket by means of the bolt 63 and the said bracket being provided with the open notch 64, adapted to receive the said bolt, whereby the spindle-holding arm 61 may be turned by hand from its normal horizontal position to the vertical position, as indicated by the dotted lines in Fig. 17, in order to obtain ready access to the end of the rotary spindle for the purpose of removing the milling-tool 59 or inserting a milling-tool in the tool-holder 66 of the spindle, the said tool-holder being shown enlarged in Figs. 18 and 19 and in enlarged section in Fig. 22, the operation of the screw-cap 67 upon the slotted conical portion 68 of the toolholder being such as to cause the milling-tool 59 to be firmly held for rotation with the spindle, the said milling-tool being provided with a beveled edge 69, whereby the end of the wire 21 will be trued up in conical form, as shown in Fig. 21. WVithin the cylindrical bore 71 is secured the bearing-sleeve 72, and at the rear of the said fixed bearing-sleeveis placed the loose sleeve 73, and between the pulley 74, attached to the spindle and sleeve 73, is placed the spiral spring 75, which is adapted to carry the spindle to its rearward position. The rear end of the rotary spindle 60 bears against the inner face of the lever 76, which is pivoted at the point 77 to the spindle-holding arm 61, and the said rotary spindle is actuated in the forward direction to bring the cutting-tool into action by means of the cam 78, secured to the rock-shaft 48. The downward movement of the sliding bar 57 serves to cut off the needle-blank from the continuous feed-wire and carry it downward to a position in front of the forcer 79, a guiderest 80 being provided to support the projecting end of the blank. The forcer 79 is provided with a collar 81, against which the spiral spring 82 presses, and with an adjustable rack 95, the rearward movement of the forcer being effected by means of the cam 83, secured to the rock-shaf t 84, the said rock-shaft being actuated by means of the rotary cam 85, secured to the hub of the cam-wheel 86, the said cam 85 being caused to act upon the roller 87 upon the lever 88, to the outer end of which is jointed the connecting-rod 89, by means of which connection is made to the outer end of the arm 90, secured to the said rock-shaft 84 The rocking movement of the cam 83 causes the holding-jaws of the rotary carrier 96, the

said rotary carrier being provided with the series of sliding spindles 97, each provided with thesplitholding-jaws 98and withaforcer 99, (see Fig. 15,) by means of which the completed blank is to be discharged, the said holding-jaws being closed upon the inserted blank by means of the conical end 100, which is embraced by the conically-bored head 101, secured to the outer tube 102 of the sliding spindle of the carrier. Within the bore of the outer tube 102 is placed the jaw-holding spindle 103, to the end of which the holdingjaws 98 are secured, and within the longitudinal hollow of the spindle 103 is placed the forcer 99, the forward portion 104 of which is made concentric, while the rearward portion 105 is eccentric and provided at its rear end with a projecting lug 106, by means of which the said forcer may be actuated in a forward direction, and having a spiral spring 107 at its forward concentric portion adapted to cause the rearward movement, the said forcer being caused to move forward to discharge the finished article by the engagement of the lug 106 with the fixed cam 108. (Shown in Figs. 8 and 9.) The jaw-holding spindle 103 is forced forward to close the holding-jaws upon the blank by means of the wedge 109, which is forked, as shown in Fig. 25, to receive the eccentric portion 105 of the forcer, the said wedge being caused to act upon the antifriction-roller 110, and thus force the tapered holding-jaws 98 forward into the conicallyborcdhead 101,and thus closing the jaws upon the blank by means of the spiral spring 111, which is held upon the cylindrical shank 112 of the wedge between the loose rectangular washer 65 and the elongated shoe 113, secured to the lower end of the shank 112 and loosely held in the slot-opening 118 of the carrier, and the releasing or opening movement of the holding-jaws is effected by means of the fixed cam 114, located at the upper side of the sleeve 115, the shoe 113 coming in contact with the said cam at every revolut-ion'of the carrier, and thus causing the outward movement of the wedge against the inwardly-directed action of the spring 111. The outer end of the wedge 109 is held in a slot-opening 116 made in the outer tube 102, and the rectangular washer 65 is held in place by means of the shoulders 8 8, so that the outer tube 102 will form the required base for the action of the wedge to cause the forward movement of the jaw-holding spindles 103 within the bore of the outer tube 102.

Upon the outer tube 102 is placed the collar 117, which serves to limit the backward movement of the sliding spindle, the said backward movement being effected by means of the sliding head 33, which is held upon the shaft 119, to which the carrier 96 is secured and controlled in its movement by the guide 120, which serves to hold the sliding head in its vertical position, The shaft 119 is made hollow for part of its length to receive the sliding spindle 121, which is connected with the sliding head by means of the screw-threaded sleeve 122, through which the spindle passes, and between thecollar 123, which rests against the shoulder 124 and the inner end of the sleeve, is placed the spiral spring 125, and between the nut 126 and the outer end of the sleeve is placed the spiral spring 127. The sliding spindle 121 is thus yieldinglyconnected to the sliding head. The forward end of the sliding spindle is provided with the cross-pin 128, which passes through the diametrically opposite slots 129 in the shaft 119 and into the hub of the disk-arms 130, the ends of which are provided with the sliding spring-actuated pushers 131, provided at their outer ends with a head 132, against which the spring 133 is arranged to act, the said head 132 being held by the said spring in engagement with the washer 65, which is in engagement with the sliding spindle of the carrier. The forward-and-backward movement of the sliding head and the sliding spindle 121 is effected by means of the forked lever 134, to which is jointed the connectingrod 135, the said connecting-rod being jointed to the lever 136, which is actuated by means of the grooved side cam 137, bolted to the reciprocating bar 138, and the stud 139 and antifriction-roller 140, which engages with the slot of the cam. The reciprocating bar 138 is actuated in its up-and-down movement by means of the cam-groove 141 in the face of the cam-wheel 86 and the antifrictionroller 142,held upon the stud 143. The upper end of the lever 136 is provided with the bearing-shoe 144, (see Fig. 5,) which serves by engagement with the rear end of thelowersliding spindle 97 of the rotary carrier to impart forward movement to the said spindle. 4 The reciprocating bar 138 is also provided with the attached

cams

145 and 146, which act upon the antifriction-rollers 147 and 148 (see Figs. 8, 36, and 37) of the

levers

149 and 150, the said levers being pivoted upon the rod 151 and actuated toward the face of the cams by means of spiral springs 152 and the bearing-shoes 153. The upper ends of the levers 149 and are provided with the

bearingshoes

154 and 155, which are adapted for engagement with the rear ends of the sliding spindles of the rotary carrier which lie in the horizontal plane of the axis of the shaft 119, to which the carrier is attached, so that upon the upward movement of the reciprocating bar the several sliding spindles of the carrier (except the upper one) will be carried forward for the proper insertion of the blanks between the swagingdies. The shaft 119 is rotated intermittently by means of the gear-segment 156, secured to the hub of the cam-wheel 86, (see Fig. 5,) the said gear-segment engaging with the gear 157, secured to the shaft 119, and to the hub of the gear 157 is secured the disk 158, provided upon its edge with the notches 159, adapted to receive the projection 160 of the springactuated pawl-lever 161, the said pawl-lever being thrown out of engagement with the notch 159 by means of the cam 162, which engages with the arm 163 of the said lever just prior to the engagement of the teeth of the gear-segment with the teeth of the gear 157, by means of which the shaft is rotated, and

by means of the notched disk and pawl-lever with the actuatingspring 167 the sliding spindles of the rotary carrier are held successively in line with the axes of the swaging-dies. The swaging-dies 164 are held in a diametrical groove 165, made in the enlarged head 166 at the forward end of the rotary swaging-spindle 15, as shown in Figs. 30 and 32, the beating-rollers 168 being held in cylindrical recesses made in the solid frame, and the beating-hammers 169 being arranged between the beating-rollers and the swagingdies. The swaging-spindle shown in Figs. 29, 30, and 31 is the one of the series by means of which the needle-blank is finished and its end cut off to the required length. The swaging-spindle 15 is made hollow and provided with the driving-pulley 16, and within the hollow of the swaging-spindle is held the steel tube 171, provided with the transverse opening 172, in which is placed the sliding cutter 173 for severing the wire of the blank, the said cutter being operated to cut off the end of the finished blank by means of the camlever 174, the face 175 of the cam being held out of engagement with the projecting ends of the sliding forcers 176, arranged at opposite sides of the cutter and by means of which the said cutter is operated, the said forcers being held in diametrical perforations made of the recess 177 upon the continued revolu-' tion of the swaging-spindle, the said cutter and forcers taken together being made to fit the cylindrical bore in which the spindle revolves. The cam-face 175 is held out of engagement with the ends of the forcers by means of the spiral spring 179 and its sliding shoe 180, the said spring acting against the under side of the cam-lever 174 to press it against the stop-shoulder 182, and the camface 175 is thrown into aposition for engagement to cut off the wire of the blank by means of the cam-operated bar 183, which carries the rack 91. The desired adj ustability of the movement to be imparted to the cam-lever 174 is effected by means of the adjustingscrew 184.

In front of the swaging-dies are placed the guides 185, adapted to receive the forward ends of the sliding spindles 97 of the rotary carrier, and thus firmly hold the same in proper alinement with'the dies, and the said guides may be provided with the side notches 186 in order to provide for the projection of the blank operated upon from the holding-jaws of the sliding spindles of the carrier, so that the needle-blank need not be drawn backward to clear the extreme limit of the guides in order to provide fort-he continued forward movement of the carrier-spindles.

The downward movement of the sliding head 57, which carries the cutting-die 56 for severing the initial blank 9 from .the feedwire, is effected by means of the arm 191, secured to the rock-shaft 84, the said arm being provided with a stud 192, which enters the slot 193 made in the sliding head, the said slot being so formed that upon the initial downward movement of the outer end of the arm 191 a corresponding downward movement will be imparted to the sliding head, but when the extreme downward position has been reached, as determined by the adjustable stop-nuts 194, the movement of the arm 191 will continue, the stud 192, passing into the downwardly-curved portion of the slot 193 without imparting further movement to the sliding head.

The driving-cams are actuated by means of the cone-pulley 187 upon the shaft 188, at the opposite end of which is secured the gearpinion 189, engaging with the teeth of the gear 190 at the edge of the cam 85.

In the operation of the machine the millingtool is brought forward to true up the end 'of the feed-wire 21, and then the downward movement of the sliding head 57 serves to cut ofi the initial cylindrical blank from the wire and carry it down to a position in front of the forcer 79,with the outer end of the blank resting upon the guide-rest 80. The forward movement of the said forcer will then carry the blank 9 forward to a position between the holding-jaws 98 of the sliding splindle 97 of the rotary carrier 96, as shown in Fig. 15, the said jaws-being opened to receive the blank by means of the cam 114, and upon the subsequent rotary movement of the carrier by means of the gear-segment 156 the blank will be carried by the holding-jaws to a position in front of the dies of the rotary swagingspindle 13. Then the action of the cam 145, attached to the reciprocating bar 138, will cause the forward movement of the carrierspindle 97, the projecting forward end of the said spindle passing into the cavity of the.

guide 185, which serves to hold the said end so that the blank to be operated upon will be held in true line with the axis of the dies, and simultaneously with the forward movement of the carrier-spindle 97 by the action of the cam 145 the action of the cam 137 upon the lever 136 will cause the backward movement of the sliding head 33, and the connected spring-actuated pusher 131, which serves to hold the rear end of the carrierspindle in close contact with the bearing-shoe 144 of the lever 136, and by means of the yielding pusher 131 variable forward movement may be imparted to the carrier-spindle under a uniform yielding pressure. When the blank has been operated upon by the dies of the swaging-spindle 13, and thus reduced from the cylindrical form shown in Fig. 44 to the form shown in Fig. 45, and the direction ofv the movement of the cam 137 reversed, causing the withdrawal of the blank from the swaging-dies, the action of the rotary gearsegment 156 will cause the rotation of the carrier, so that the blank will be carried to a position in front of the swaging-spindle 14. Then the action of the reciprocating cam 137 upon the lever 136 will effect the forward movement of the carrier-spindle 97 to carry the blank between the dies of the said swaging-spindle to cause the further reduction of the form of the bla n k to i he form shown in Fig. 46, and upon the withdrawal of the blank from the said dies by the downward movement of the cam 137 the continued rotary movement of the carrier will carry the blank to a position in front of the swaging-spindle 15, and the action of the cam 146 upon the lever 150 will serve to carry the blank between the swaging-dies of the said spindle, and by means of the said dies the blank will be still further reduced and extended, as shown in Fig. 47, and its end trimmed to the required length by means of the sliding cutter 173. The blank is then withdrawn from the dies by the down ward movement of the cam 137, and upon the continued rotation of the carrier the shoe 113 of the wedge 109 will engage with the cam projection 114, whereby the holding jaws 98 will be opened to release the blank, and at the same time the lug 106 will engage with the fixed cam 108 to effect the forward movement of the forcer 99 to cause the discharge of the finished blank from the jaws preparatory to the reception of a fresh cylindrical blank as before.

By the employment of the fixed cam 108 for discharging the finished blank when'the carrier is in motion instead of discharging the blank when the carrier is at rest I am enahled to dispense with one of the sliding spindles which would otherwise be required in the carrier, which constitutes a desirable improvement.

Any desired number of rotary swagingspindles may be employed in combination with a rotary carrier having sliding spindles and holding-jaws for transferring blanks from the swaging-dies of one rotary spindle to the swaging-dies of another spindle in connection with means for inserting the blank between the holding-jaws, and means for discharging the finished blank.

I claim as my invention- 1. In a machine for making needle-blanks or similar articles, the combination of means for feeding the wire forward, and clamping means fpr holding the wire in its forward position, with a rotary cutter for milling the forward end of the wire, the reciprocating carrier provided with a cutting-die adapted to hold the milled blank when severed from the wire, and the forcer for forcing the sev ered blank endwise and forwardly from the cutting-die, when the carrier is in its delivering position, substantially as described.
