To all whom it may concern.

Be it known that T, MICHAEL J. RILEY, a citizen of the United States, residing at East Cleveland, in the county of Cuyahoga, State of Uhio, have invented certain new and useful Improvements in Bolt Machines, of which the following is a specification.

While in some aspects of more general application the invention relates particularly to a machine which will automatically size under the head of a headed blank or bolt or which will automatically shave or finish the top of such head or perform both operations.

n general the invention includes a hopper into which the blanks or bolts may be thrown promis'cnously. They may be assorted and arranged and passed from the hopper to a chute at the end of which they may be received by suitable mechanism for delivering them into position to be grasped and held or rotated while a cutting device 'may operate on them.

In one aspect the invention includes a spindle provided with a chuck or collet for grasping the work associated with means for rotating the spindle and operating the collet and cutters which may be moved to suitably attack the work. The cutters may have movement transverse to the axis oi the work or parallel thereto or in both directions. A support for the work may be provided near the point of attack by the cutting tools. The support itself may have suitable movement to adapt it to the work and to allow of ingress and egress of the work.

One phase of the invention contemplates picker fingers which bring the work into alignment with the collet so that it may be grasped. Associated with the picker fingers may be a positioning device tending to p shaft. Fig. 16 is a side elevation of the cam properly hold the work before the collet to be grasped. The positioning device may be resiliently or yieldingly mounted. A device may be provided for kicking the work from the picker fingers in their retracted position and this device ma move with the fin ers.

The spindle may e mounted in a hea adjustable toward and from the picker fingers and the cutting tools and may be associated with mechanism for reciprocating it and for operating the collet carried by it so arranged that when the relative location of the spindle and mechanism has been once ,ldetermined the whole may be adjusted as fa unit without varying such relative location.

tions and, therefore, it is not limited to the particular structure illustrated.

In the accompanying drawings Figure 1 is a plan view of the machime the hopper and associated mechanism havin been removed. Fi 2 is a front elevation of the machine. ig. 3 is an end elevation from the right of Fig. 31. Fig. t is an end elevation from the left of Fig. 1; Fig. 5 is a dc tail elevation of the device for receiving the blank from the chute and its operating mechanism.

Fig. 10 is a fragmentary elevation of the picker fingers for carrying the bla and their operating mechanism. Fig. ll is a front elevation of the picker fingers. Fig. 12 is a fragmentary longitudinal section through the spindle. Fig. 13 is atransverse section through the spindle showing portions of the mechanism for operating it and the collet. Fig. it is a developed view of the cams for operating the spindle and collet. Fig. 15 is a fraentary section showing art of the mechanism for rotating the cam for actuating the support or roller rest for the work and Fig. 17 is a developed view of the cam for moving the tool.

The machine comprises a bed 1 on which is supported a drive shaft 2 provided with a drive pulley 3. The drive shaft carries a gear 4 which engages a ear 5 on a jack shaft 6. The jack shaft 6 a so carries a gear 7 which engages a gear 8 on a second jack shaft 9. At its inner end the jack shaft 9 carries a bevel gear 10 which engages a bevel gear 11 on a transverse shaft 12' which carries a worm 13 engaging a worm gear 14 on a cam shaft 15. This train of gears may (ill provide for a reduction of speed between the drive shaft and the cam shaft and their relative speeds may be altered by replacing one or more of the gears. Y

The frame of the machine supports a ho per 16 into which headed blanks may e thrown promiscuously. The hopper 16 is provided with a chopper 17 of a well known form to properly arrange the blanks. A roller 18 is carried by an arm 19 mounted on'a transverse shaft 20 which carries a bevel gear 21 engaging a bevel gear 22 on a shaft 23 which also carries a sprocket 24 driven by a chain 25 passing. over a sprocket 26 on the cam shaft 15. As the arm 19 rotates it causes the roller 18 to wipe the are shaped bottom 27 of the chopper 17, thereby causing it to rise and fall in the hopper to arrange the blanks in the well known way. spring 23 on the shaft 23 allows the sprocket 24 to rotate on the shaft to relieve the mechanism should the chopper stick or be locked by misplaced blanks. The blanks are arranged in the chopper so as to hang by their heads and at the upper end of the chopper stroke ,those so arranged slide by gravity into the chute 28 which, as shown, is provided with a guard 29 to keep the blanks in order.

At its lower or outlet end the chute 28 is provided at each side with a lock 30, which may be forked, pivoted at31 on the chute side and forced by a spring 32 into the mouth of the chute so as to prevent blanks from dropping out. (See Fig. 9.) The outer Sides of the locks 30 are beveled toward their meeting point and each lock is provided with a set screw 33. It will be noted that the locks 30 as shown extend nearly to the top edge of the chute 28 and so engage the lowermost bolt close under the head and thus the heavier head may be prevented from tipping the bolt or prematurely pulling it from the chute end.

A transverse shaft 34 carried in bearings 35 on the bed of the machine carries at one end a transverse carrier arm 36. At its other end the shaft 34 carries a pinion 37 which is engaged by a toothed are 38 on one end of an arm 39 pivoted on the bed at 40. At its other end the arm 39 carries a roller 41 adapted to be engaged by a cam 42 mounted on the cam shaft 15. The cam 42 is shown in elevation in Fig. 6 and developed in Fig. 7. A spring 43 mounted on the bed of the machine bearsagainst the arm 39 and tends to hold the apparatus in position to cause the transfer arm 36 to be in a horizontal position. A stop 34 adjustable on the shaft 34 engages a web 35 in the bed and limitsthe movement of the transfer carrier arm 36 as. caused by the spring 43 to such as will cause the arm 36 tobe substantially horizontal. As it rotates the cam 42 engages the roller 41 so as to cause the toothed arc 38 to rotate the pinion 37 and swing the transfer carrier arm 36 through about 60 upward from the horizontal to the outlet of the chute .28.

The face of the transfer carrier arm. 36 is beveled at 45 so that as it approaches the locks 30 the bevels 45 engage the set screws 33 or the bevel face in the locks 30 and so force them to separate against the pressure of the springs 32. The set screws 33 may be A entirely. This allows the lowermost blank in the chute to drop by gravity into the cavity 46 on the transfer carrier arm 36. The transfer carrier arm, weighted down by the blank, then returns, under'pressure of the spring 43, to its horizontal position, as allowed by the stop 35 and the cam 42, carrying the blank with it. If it is found that the blank is heavy enough to depress the transfer carrier arm the spring-43 may be omitted. The locks 30 return, under pressure of the springs 32, to the position to hold the remaining blanks in the chute as-soon as the beveled faces 45 leave the set screws 33.

A longitudinal shaft 47 mounted in the bed of the machine carries a rearwardly extending arm 48 on which is a roller 49 en gaged by a cam 50 on the cam shaft 15. The shaft 47 also carries a forwardly extending arm 51 provided at its forward end .with a fork 52 in which is a transverse pin 53. A coil spring 51 fastened to the bed 1 and the arm 51 tends to hold the forward end of the arm substantially horizontal and also holds the roller 49 against the edge of the cam 50. In Fig. 1 a coil spring 51 surrounding the shaft 47 may augment .or replace the spring 51*. Pivoted on the pin 53 are

jaws

54 and 55 acting as .picker fingers for the blank. At their tips the jaws or fingzers 54 and 55 may be forked as shown in ig. 11. The jaw 55 carries a set screw 56 by which the distance between the jaws coil spring 61' tending to force together the lower ends of the jawsas allowed by the set screw 56. A coil spring 62 surrounds raeaeee the rod 59 between the lug 60 and the jaw 54 and tends to hold the 'aws as a unit against the set screw 58. The icker finers thus are normally held in xed os1- tions but they are held resiliently an are capable of suiting themselves either separately and individually or as a unit to the pieces and parts with which they co-act or engage.

The transfer carrier arm 36 swings in a plane which is a continuation of the plane of the chute 28 and the arm 51 is so mounted and operated that it may extend the gripper fingers into the same plane. The transfer carrier arm receives the blanks in a substantially upright position and moves them to a substantially horizontal position. The cam 50-isso formed and timed as to cause the picker fingers made up of the

jaws

54 and 55 to descend upon and grasp the blank in the horizontal transfer carrier arm 36. The springs 61 and 62 ive sufficiently to allow the fingers 54 an 55 or their forked tips to separate and enter the openings 63 through the bevels and the sides of the cavity 46 in the carrier arm 36. The picker fingers now may grasp the blank and remove it from the carrier 36 as the cam causes the arm 51 to rise. The picker fingers rise to allow the transfer carrier arm 36 to move past them toward its upright position and then the picker fingers move back and further downward past their former position so as to brin the blank about on the level with a col et 64. The blank is maintained substantially horizontal so long as it is held by the picker fingers in which position it is grasped and rotated by the collet.

Pivoted on the shaft 47 is an arm 65 which is connected to the arm 51 by a spring 66. The forward end of the arm 65 may have two fingers 67 and 68. The finger 67 extends between the prongs of the forked end of the picker fingers. The finger 68 extends adjacent the picker fingers on the side away from the transfer carrier arm 36. The spring 66 tends normally to hold the fingers 67 and 68 of the arm 65 above the gripping surface of the picker fingers 54 and so that they are free to grasp a blank. The arm being loosely mounted on the shaft 47 is free to move with the arm 51. When the arm 65 has been carried by the arm 51 to nearly the upward limit of movement of the arm 51, a projection 69 from the arm 65 engages a pin 70 extending from the bed of the machine. At this point the pin 70 stops the further movement of the arm 65 and expands the spring 66 as the arm 51 moves further upward. At this time the

grippin jaws

54 and 55 wipe past the fin ers 67 an 68 which causes any blank carrief thereby to be ejected. The normal movement of the picker fingers after receiving the blank from the transfer carrier 36 is upward a slight distance but less than their full upward movement. This movement does not bring the kick out fingers 67 and 68 into operation. Normally the icker fin ers then move downward and deiver the lank to the collet. If, however, the blank is misshapen or misplaced or for any reason it is not grasped b the collet it may be retained in the picker ngers in their final movement to their full upward position. In this event the pin 70 causes the blank so carried to be ejected from the icker fingers which are thus left empty an prepared to receive the next blank presented to them by the transfer carrier arm 36.

Extending laterally from the fork 52 which carries the

picker fingers

54 and 55 is an arm 71 provided with a socket 72 in which is a coil spring 73 on which rests a plunger 74. The arm 71 extends from the side of the fork 52 which is away from the transfer carrier arm 36 and the plunger 74 is held at such a position that it is approximately in alignment with the ipping point of the picker fingers 54 an 55. The head of the blank lifted from the transfer carrier arm 36 by the

picker fingers

54 and 55 rests against the plunger 74 which bein supported by the spring 73 allows blanks of varying sizes and variously positioned in the transfer carrier arm 36 to be properly received by the

picker fingers

54 and 55. If not grasped by the collet the blanks may be forced, by contact of the moving spindle, against the spring supported plunger 74. The springs 61 and 62 allow the

fingers

54 and 55 to ive sufiiciently to permit the blank to slide t rough the fingers and compress the spring 73. This prevents the a paratus from jamming or becominginjured or disarranged.

The drive shaft 2 carries a long gear which slidably engages a gear 91 on a reciprocating spindle 92 carried in an adjustable head 93 resting on the bed of the machine. The long gear 90 may be held in place on the drive shaft 2 by means of a set screw so that it is adjustable along the shaft. The adjustable head 93 carries a transverse rod 171 on which are the bearings 172 for a yoke 173 from which extends rearwardly an arm 174 carrying a roller 75 which is enga ed by a cam 76' mounted on a drum 77 which is adjustably held on the cam shaft 15 by a set screw 78. In ways 79 atthe lower end of both arms of the yoke 173 are trunnion blocks 80 engaging trunnion pins 81 on a trunnion collar 82. The trunnion collar 82 rests between thrust bearings 83 and 84 held by lock'nuts 85 on a sleeve 86 adjustably fastened on the spindle by a set screw 87. The spindle 92 carries at its end the collet 64 and through the yoke lever 173 it may be reciprocated in the head 93 so as to cause the collet to advance and surround the blank brought into alignment with 1t by the

picker fingers

54 and 55. A. stop 88 is held in the base of,..the head 93 b screws or bolts 89 in such position as to by the trunnion ring 82 so as to limit the forward movement of the collet carried by the spindle. On the rear end of the shaft 171 is fastened by a set screw 94 a rearwardly extending arm 95 carrying a roller 96 which may be engaged by a cam 97 car ,ried on the drum '77 on the cam shaft 15. Mounted on the forward end of the shaft 171 by a set screw 97 is a downwardly extending arm 98 which engages a link 99 extendin to the left in Fig. 2 to engage one arm of t 1e yoke 100 pivoted at 101 to a lug 102 extending from the head 93. The yoke 100 engages a collar 103 of a cone 104 moun ed to slide on the s indle 92. Anfgle levers 105 pivoted on a isc 106 have orwardly extending arms 187 enga ed by the cone 104. The levers 105 have wel ted extensions 108. The disc or collar 106 is pinned to a shaft 107 which extends through the center of the spindle 92. The jaws 208 of the collet 64 are screwed to the end of the shaft 107 opposite the end carrying the disc 106. Surro :ndin the shaft 107 is a coil spring 109 resting between the inner end of the jaws 208 and the bottom 110 of a socket in the spindle 92. lVithin the shaft 107 and at the end carrying the collet is a long socket in which rests a plunger 111 on a coil spring 112. The outer end of the plunger 111 normally rests between the jaws 208 of the collet. The outer side of the jaws 208 of the collet are beveled and engage correspondingly beveled surfaces of a hood 117 mounted on the end of the spindle 92.

The spindle 92 is continuously rotated through the gears 90 and 91 and centrifugal force working on the weighted ends 108 of the levers 105 keeps the arms 187 in contact with the surface of the cone 104. Movement of the cone 104 toward the right in Fig. 2 will therefore tend to draw the disc 106 toward the end of the spindle 92. This will force the shaft 107 to the right: in Fig. 12 and co-operate with the expanding spring 109 to allow the collet jaws 208 to ride to the right through the hood 117 and so open to release a blank and to be in condition to receive a blank. A blank held in the

picker fingers

54 and 55 with its head resting against the spring supported plunger 74 will be approached by the collet as the spindle advances in such a way as to cause the plunger 111 to engage the free end of the shank of the blank. The spring 73 is strong enough to overcome the spring 112. The plunger 111 will thus be depressed and the spring 112 compressed as a blank is grasped by the collet jaws 208. When therefore the collet jaws 208 are freed from the blank, the

engaged 4 spring 112 will cause the lunger 111 to e ect the blank frdm the co et.

-The cams 76and 97 are so arranged and associated with the other parts of the machine that the spindle is reciprocated to approach the blank and cause the collet to surround it. The cone 104 is then shifted to cause the collet to closeand the parts are held in this osition while the cutting operation is per ormed, Then the cone 104 is shifted to open the collet as the spindle recodes to allow the finished blank to be ejected and another supplied.

After the blank has been grasped by the collet and the

picker fingers

54 and 55 have been withdi'awn therefrom a back rest (here shown as rollers 119 and 120) may be brought into en agement with the blank preferably just below its head. An angle lever 121 pivoted on the frame of the machine carries at its upper end a bolt 1.22. Partly surrounding the bolt 122 is a half bearing in an arm 123 which carries the roller 119. lartly surrounding the bolt 122 is a half bearing of an arm 124 carrying the roller 120. The split bearings of the arms 123 and 124 engage and limit the separating movements of the rollers 119 and 1.20 caused by their coming in contact with the rotatingb a nk. Set screws 125 carried by the lever 121 may also be provided to limit. the movement of the arms 123 and 124. The lower end of the lever 121 is engaged by a link 126 connected to the lower arm 127 of an angle lever pivoted at 128 to the bed of the ma chine. The other arm 129 of the angle lever carries a roll 130 which may be engaged by a cam 131 on the cam shaft '15. The form of the cam 131 is shown in detail in Fi 16.

' A turn buckle 132 is provided on the lin i 126 to vary and adjust its length. Between the turn buckle 132 and the bearing 133 in the bed for the link 126 is a coil spring 134 surrounding the link and tending to hold the roller rests 119 and 120 out of the path of the blank. The cam 131, however, engages the roller 130 and compresses the spring 134 and causes the

rollers

119 and 120 to engage the blank and support it as it rotates.

A transverse slide 136 in the bed of the machine is provided at its rear end with a roll 137 which may be engaged by a cam 138 on the cam shaft 15. Depending from the slide 136 is :1 lug 139 resting against a coil spring 140 on an abutment 141 in the bed of the machine. The tendency of the spring 140 is to force the slide 136 toward the right in Fig. 3 and so keep the roll 137 in contact with its cam 138.

Resting in transverse wa s 142 in the slide 136 is a tool block 143 w ich may carry tools 144 and 145 of any suitable shape. To a projection 146 on the tool block 143 is pivoted one end of a lever 147. The other end of the lever 147 extending to the rear esa-see of the machine, carries a. roller 148 riding in a scroll cam 149 on the cam shaft '15. The cam 149 is shown developed in Fig. 17. Passing through a longitudinal slot 150 in the center of the lever 147 is the vertical pivot pin 151 tapped into a plate 220 slidably mounted on the bed of the machine. Rising from the lever arm 147 at eachend of the slot 150 is a lug 152 in which is an adjusting bolt or screw 153 provided with a lock nut 154. The bolts 153 engage a hearing collar 153 on the pivot pin 151. By turning and adjusting the bolts 153 the position of the plate 220 and thus of the dpivot pin 151 in the slot 150 may be varie and thus ma be varied the throw of the forward end of t e lever 147 engaging the tool block 143. When desired either tool may be omitted and the machine operate with one suitably formed tool.

At the time the blank is delivered to the collet, the roller rests 119 and 120 are withdrawn from the path of the blank and the slide 136 carrying the tools 144 and 145 is retracted toward the right inFig. 3, After the blank has been grasped by the collet and while being held and rotated the roller rests 119 and 120 advance and support the blank and then the slide 136 is forced toward the blank. At this time the cutting tools are about in the position shown in Fig. 1 where the tool 144 is below the head of the blank and the tool 145 is beyond the head of the blank. After the tools have beenadvanced toward the blank in a direction transverse to its axis the cam 149 causes the lever 147 to shift the tool block 143 in a direction par allel to the axis of the rotating blank, first in one direction and then in the other so that the tool 144 will size under the head of the blank or bolt and then the tool 145 will shave or finish the top of the head or the operation might be reversed. It will be noted that the movement of the tool 144 will tend to draw the spindle toward the right in Fig. 2 and this thrust movement may be taken up by the trunnion collar 82 engaging the stop 88 in the spindle head 93.

The rollers 119 and 120 'act as stead ing supports for the rapidly rotating b ank when it is being acted on by the cutting tools 144, and 145. After the cutting operation has been completed the cutting tools and the rollers are withdrawn and the blank may be dropped from the collet and another put in place without interference.

The positioning plunger 74 tends to assure,

the blank bein so placed that when grasped in the collet t e head will. be in position to be between the cutters 144 and145 when they are advanced to the blank.

The spindle head 93 may be adjusted along the bed of the machine toward and from the picker fingers and the tool slide 136to provide. for operation upon blanks of difierent lengths; A- hand wheel 113 operating a gear 114 engaging a rack 115 in a well mown way provides for movement of the spindle head. The usual bolts 116. are provided for holding the head in any of its adjustments. The gear 90 may be held on the driving shaft by 'a set screw so that it may be ad usted along the driving shaft as the indle head 93 is adjusted and thus the spin le may be rotated in whatever position the spindle head may Likewise the drum 77 carrying the cams for operating the spindle and collet may be adjusted along the cam shaft 15 and held by a set screw 78 so that the spindle may be roperly reciprocated and the collet operated in any adjusted position the head 93 may take.

Extending to the rear from the "head 93 are arms 118 between which rotates the drum. 77 carrying the

cams

76 and 97 for operating the spindle and the collet. When the cams have been set to properly cooperate to operate the spindle and collet the entire apparatus may be adjusted, along the bed of the machine so as to accommodate blanks of various lengths by loosening the bolts the transfer carrier arm 36 will receive a blank from the chute and deliver it into the

picker fingers

54 and 55 which will lower it into position to be sped by the collet jaws 208 as the spind e 92 advances. The

rollers

119 and 120 will then advance to support the blank. The tools 144 and 145 will then advance above and below the head of the blank. Lateral movement will be given to the tools to cause them to attack the work. They and the rollers will then recede and the finished blank will be ejected by the plunger 111 as the collet opens and recedes with the moving spindle to clear the space for receipt of the next blank.
