-' Y This improved-nut castellating machine los comprises in a general way a blank or nut carrler comprising a revoluble intermittently actuated turret and means for locking the same in successive positions; slotting mechanism comprising a series of three saws suitably mounted to slide toward and from the nut blanks and drivingmeans for rotating the saws g, feeding and positioning mechanism comprising a magazine and means for positioning the nuts. successively in the chucks of the turret; driving means for rotating the' nut-blank carrier and reciprocating the saw carrier toward and from the blanks and for operating the nut blank positioning means, and which driving means includes in the preferred embodiment of the machine, change gear mechanism by means' of which the relative speeds of the nut blank carrier and saw slide may be regulated or changed; and mechanism for opening and closing the nut blank chucks and for remov- I ,ing the finished product lfrom its chuck.

A This improved machine is mounted upon a suitable base 2 comprising the usual oil pan and 'supports or standards 3, and to this base is bolted a suitable bed 4 on which,

at one end,is housed in a circular casing 5 a cylinder or turret 6, forming a part of Vthe blank carrier. the work spindles 7, each of which is provided with a suitable chuck, six spindles being shown in the present instance mounted in the rotary cylinder. This cylinder is provided at one end with a gear disk 8 having its gear teeth 9 disposed in sets spaced apart and by means of which the rotary nut blank carrier is intermittently rotated, this being accomplished by means of a fan gear 10 mounted on a shaft 11 supported at one end in the bed of the machine and at its opposite end in a bracket 151 hereinafter referred to, and which shaft is rotated by 3 means of a worm wheel 12, (left hand), in

mesh with a worm 13 carried by a shaft 14 supported transversely of the bed and carrying a change gear more fully described hereinafter, on its outer end, which is driven from a pulley 15 mountedj on a stud 92.

From the foregoing it will be observed that on each rotation cf the t'an gear it will engage one set of teeth of thenut blank carrier and rotate the same a predetermined distance, this distance according with the distance between the axes of a pair of work spindles.

The cylinder is provided with a series of tapered sockets 16, and these sockets are spaced at equal distances apart around the cylinder, one being located between the successive work spindles. lFon-locking the cylinder at its several stations a spring actuated plunger 17 is provided, this plunger being carried in a sleeve 1'8 projecting from the cylinder casing at one side-0f the machine and has a tapered enduadapted to fit the This cylinder carries .tapered sockets l16. The outer end of this 'plunger is forked, as at 19, for the reception of ian actuating lever 20 pivotally supported on a bracket 21 secured to the side of the bed of the machine, the opposite vend of this ,lever being engaged by acam roller 22 carried on the shaft 11 and by means of which 'the llocking plunger will be withdrawn so as to release the cylinder to permit it to be revolved one station. A spring 23,

--having one end secured to a pin 24 of the lever 20 and the opposite end secured to a pin or projection 25 on the casing, tends to hold the plunger in its cylinder locking position.

Each of the work carrying spindles 26, shown as six in number and carried by the revolving cylinder, is shown in the present instance as made in two pieces, 27 and 28, screwed or welded together for convenience of 'manufacture In the present instance,

see Fig. 4, they are shown as screwed together, and each is forced into the cylinder and held in place by a collar nut 29. The outer end of the portion 28 of the spindle having the larger diameter is provided with a thread 30 for the reception of a threaded nose piece or chuck cap 31, back of which is a lock washer 32 and adjusting collar 33.

By this means the cap or nose piece is adjustable` longitudinally of the spindle and held in anyA desired position by the lock .j washer 32 and adjusting collar 33. This adjustment is essential, as it is vital that the caps of all the spindles be the same distance. from the face of the cylinder, and to also compensate for wear of the chucks and capsy or nose pieces. Within the cap of each spindleV are the spring formed `gripping jaws 34 forming the chuck for recelvmg ande holding the nut blank during the vslotting operation, which jaws are opened and closed by mechanism located at the rear end of the n spindle. Within each of the work carrying spindles is located an extractor 35 adapted to force out the completed product at the proper time, and which extractor is shown in the form of a tube and is operated from the rear end of the spindle by means hereinafter described.

Supported on the bed opposite to the cylinder for sliding movement toward and from the cylinder, is a compound slide 40,

`compounded for convenience in manufacture and assembling. On the upright or knee portion 41 of this slide 40 is tongued and bolted the saw spindle head 42 for supporting three saw spindles 43, 44 and 45 spaced apart so that they will be in alinement with the three work spindles nearest tothe saws, when the spindles are inwerking position.' Six bearings are carried by this head, two, as 46 and 47, for each saw spindle, thus forming what may be conj sidered three front bearings 46 and three rear bearings 47., .These bearings are so spaced apart laterally that the saws 48 carried thereby will be on a center line `with opposite work spindles in the blank carryany one of its sockets.

theA work spindles in the cylinder. As each of the three spindles and its bearings are the same a description of one of them will be suiicient.

The front bearing 46 of each spindle has 'a tapered interior surfacel 50 for the reception of bron-ze taperedsplit bearing members or bushings 51 adjustable for circular tension by adjusting collars 52 and 53 turned on to the threaded extended ends of the bushings 51. Each bearing is also provided with an oil chamber 54 having a wick. The forward end of each tapered bearing has an A yannular recess for the reception of a thrust washer 61, which is thus housed in back of a shoulder 62 formed on the spindle. In each v rear bearing 47 is located 4a bronze solid straight bushing 55 having the extended ends provided with threads for the reception of adjusting nuts 56 and 57. A thust washer 58 is located at' the outer end of the vspindle to rest against such outer end and is maintainedin position by a nut 59 turned on to the threadedend of the spindle 60. The saw is clamped on thespindle by means ofa nut 63 and collars 64 between the shoulder and the nut 63.

From the foregoing it will be lseen that when the spindles are in place and it is desired to loosen or tighten, or in `other words, to take"Y up or loosen the spindles, it is only necessary to manipulate the tension nuts 56 and 57 in the proper direction; that is to say, if the spindles have too much endwise movement or play the thrust cap 57 is loosened and thrust cap 56 is screwed up against its bearing, thus drawing the bushing 55 against thrust washer 58 and so taking up the play. If the tension is too tight the opposite movement will effect the loosening thereof. To take up .the circular tension at the forward endof the saw spindles, the adjusting caps or nuts 52and 53 are manipulated in the same Way, but the bushings being tapered on4 their periphery and split, and the bearings being tapered' on their interior to correspond with such tapered bushings, the action of the adjusting caps results in forcing the bushings against the periph*- ery of the spindles, thus loosening or tightening the'tension of the bushings on the spindles.

For rotating the sawseach spindle is provided with a bronziiJ worm gear 65 in mesh with a worm 66 carried by avertically located shaft 67 journaled in the sawh'ead 42. On a suitable shoulder on the upper end of this worm shaft is placed a thrust washer 68, ball retainer 69 'to relieve the friction,` and a thrust washer 70, and in contact with this thrust washer 70 and housed and held in place by a thrust cap 71 is a top bearing 72, which takes the vertical or` upward thrust of the worm'shaft 67 when the saws are in action. To lessen the thrust of this worm shaft when the saws' are in actilun the upper and lower saws are formed and driven so that they cut downward, thus requiring right hand threads on the worm shaft for. engagement with the upper and lower gears 65 carried by the upper and lower saw spindles, which thus causes the worm shaft`to thrust upward against the top bearing or bushing 72, while the intermediate or center saw is formed and driven so as to cut upward, for which purpose the intermediate worm on the worm shaft is formed lefty handed, which thus relieves the upward thrust of the worm shaft against the top bearing or bushing 72 when the saws are in action, so that the thrust of one of the saws upward and against this bushing is counteracted or counterbalanced by the thrust of the intermediate saw so that the thrust bushl ing 72 receives the thrust of only one saw spindle.

On the lower end of the worm shaft is fastened a bevel gear 73 which meshes with a bevel gear 74, see Figs. l and 9, fastened to a shaftl 75 having a suitable bearing at one end in the saw slide hereinbefore referred to. The opposite end of this shaft vhas a bearing in the bed 4 and also in a bracket 76 fastened to said bed 4, and on the outer end of this shaft, between the two last mentioned bearings', is fastened a driving pulley 77, by means of a sliding key or keys,

which thus permit the saw slidevto have a sliding movement together with endwise movement of the shaft 75 for imparting rotary movement to the saw spindles, while the driving pulley 77 has simply a rotary movement, without any endwise movement with its shaft. y

To'reciprocate the saw slide toward and from the revoluble turret and the work carried thereby, the transverse shaft 14 carries a worm 78, (right hand), in mesh with a worm wheel 79 secured to a shaft 80 journaled in suitable bearings of the bed 4 and parallel with the direction of movement of .the saw slide. On this shaft 80 is keyed a cam drum 81, on the periphery of which is fastened a suitable cam 82 so formed on its outer edge that when it is set to comein contact with a roller 83 depending from the o saw slide it will carry such slide forward .toward the blank spindles in the turret the required distance necessary to slot the blank the proper depth. A second cam 82', see

dotted lines Fig. 6 and also Fig. 7, is so placed on this drum that when the saws have cut the required depth thesaw slide will be returned to its initial position, and it will be observed that the saw slide is offset from direct alinement relatively to the revoluble turret or cylinder so as to bring the saws on the spindles in center position with the work spindles carried by this cylinder on the left or lock-bolt side of the machine. The roller with which the cam carried by the drum 81 engages is carried by a stud supported by a slide strip adjustable lengthwise of the saw slide by means of a bolt 84 working in lan elongated slot 85 of the saw slide, and by means of which devices the cam engaging rol'ler may be adjusted.-

A suitable oil pump 86 is shown in the present improvement, driven from the pulley 7 7 by means of a sprocket cham 87 On one end of the shaft 14 is located a suitable change gear 90 covered by a suit able housing 91. At one side of this gear, and secured to the bed 4, is a stud 92, on which stud a bracket 93 is supported for swinging movement, and this bracket has a pair of arms 94 and 95 located at right angles to each other, the arm 94 having an elongated slot 94, see Fig. 14a, for the reception of a bolt 96 projecting into the bed 4, whereby this bracket may be adjusted.

The other arm 95 carries a stud on which a gear 97 is located in position to mesh with a gear 98 keyed rmly to an extension of a bushing 99 loosely mounted on the stud 92. The gear 97 is in mesh with the change gear 90 carried on the end of the shaft 14, and when this gear 90 is changed to a larger or smaller gear the gear 97 can be swung into position to mesh therewith by means of the elongated slotted arm hereinbefore referred to. On this loosely mounted bushing 99 is the pulley 15 hereinbefore referred to, which is also loosely mounted to rotate freely without endwise or lateral movenient, suitable thrust washers`101, 102, the

latter held in place by a lock nut 103, being used to permit the pulley to rotate freely and without end or lateral movement. To the outer side of this pulley 15 is bolted a clutch member 104, which overhangs the lock nut 103, and which clutch member just clears the bushing 99. Firmly keyed to the outer eid of this bushing 99 so as to rot-ate therewith is a companion clutch member 105, but shiftable longitudinally of such bushing to engage with the clutch member 104 thereby to impart motion from the loosely mounted driving pulley 15 to the .bushing 99 and thereby` to the system of gears and thus to the transverse shaft 14. This clutch member is grooved, as at 106, to receive a forked hand lever 107 pivotally connected, as at 108, to a bracket 109 supported on the outer end of the stud 92.

From the foregoing it will be observed that gears of any desired number of teeth may be placed on the transverse shaft 14 and by swinging the bracket arm 93 the gear carried by this bracketwill be brought into mesh with the gear carried by the shaft 14, thus get-ting any desired speed for the travel of the saw slide and the rotation of the turret. Thischange lgear mechanism forms an uninterrupted drive from the driving pulley 15 to the shaft 14, and when the clutch members are out of engagement the pulley continues to rotate while the rest of the transmission remains stationary. This system of transmission is very effective when adjusting or setting up the machine or changing the speed of the saw slide. The' opposite end of the shaft 14 projects beyond the bed 4, `as at 110, for the reception of a suitable handle by means of which this shaft 14 may be turned by hand.

For feeding the nut blanks to the rotary turret carrying the fixed and non-rotatable blank carrying spindles a magazine is provided. Secured to thecasing for the turret is a boss 120 to which is bolted by suitable elongated slots and bolts a supporting bracket 121, to which is pivotally connected the magazine, as at 122. This magazine comprises the main plate 123, which is pivotally connected as at 122, as stated, to the bracket 1 21, and a pair of adjustable side plates 124 and 125, each having at its upper and lower ends an elongated slot 126 which,

by means of bolts 127, may be adjusted toward and from each other on the main plate 123 to receive any desired size of nut blank. The side plate 125 has a top strip 128, which strip is machined to the required size determined by the thickness of the blankor wor: to be cut or slotted. In the present instance this top strip is shown adjustable,

see Fig. 13, toward and from the work, this slide 131 carrying a plunger 132 in aline- V ment with the lower work blank of the magazine, and which blank is supported by an adjustable stop 133,`see Fig. 10, shaped to accord with the periphery of the blank.

This adjustable stop is fastened to a stemf 134 carried by an arm secured by a set screw to the bracket 130, so that this adjustable p bracket 130.', On

136 1s pivotally stop'may be raised andilowered at'will to` permit thev centering of the work with the middle spindle atpvthe ,rigli'tfof the ,sawl

spindles.

connected to the slide...The lower end of thisleveris pivotally. supported byI ya crotch V the lower end.; of this .,lever, atrightangles thereto, is astud136 and roller 136, which comes vinto contact .atthe proper `time witha. pair of cams 136, seeFig.

10 mounted on the periphery of ka cam drum 150a cargried by the shaft 11, this-being the same shaft that carries thel fan gear for ro-` tating the turret, and by this mechanism the slide 131 and t-he plunger carried thereby are reciprocated back and forth'to force the i, lower nut blank from the magazine into the chuck of theswork, carrying spindle. Tension springs 138 are secured to the plunger at each tened to the slide 131,th`ese springs allowing the blanks lever 136 caused by varlation of the blanks to be cut. .The magazinebeing thus adjusted to the required width and thickness of the worka blanks and in alinement with the grips or chucks and work blanks in the cylinder, and the adjusting stop 133 being set so that the bottom work blank isproperly positioned, the plunger being forced forward will force thek lower work blank plunger to cushion against the work into the chuck or grip of one of the work` spindles. The rear side, at the lower end, of this magazine is-tapered, as at 140, see Fig. 15, and carried at the upper end of the bracket 121 is a spring pressed plunger 141 in position to enga-ge the rear side of the pivotedmagazine, the .purpose of this being to return the magazine to its proper position when the lower end of the magazine is shifted away from the work carrying spindle, which operation occurs when a blank has not fully entered into the grip or chuck. When such blank has not fully entered into the grip or chuck the tapered lower rear end of the magazine permits the blank to swing the lower end of t-he magazine on its pivot 122 away from the chuck as t-he turret commences to revolve with the partially entered blank, thus freeing the blank ,from the magazine and preventing injury to the'mechanism, which would otherwise occur if the blank could not release itself from the magazine. As soon as the blank has been released from the magazine the spring pressed plunger 141 returns the magazine to its normal position. Thus there isprovided a magazine which is adjustable for various sizes of nut blanks, both depthwise and crosswise of the blank, and is also adjustable to permit the blanks to automatically release l blanks have not fully To reciprocate ftheslide131; acrotch lever` bracket 137 bolted to-,the

For manipulating the blank carrying chucksand extracting.y the nut blanksfwhen`r entered the chucks of the b same have-been `slotted suitable. operat f ing mechanism has .been shaft 11 carrying the fan gear is located a car'n drum-.150, on the periphery of lwhich arefastened cams for operating all of 'the provided. On1 .the

levers necessary to perform the operations f,

and opening kiso anextended bearing 152, to which is pivot-f= ally secured on the magazine side of the bed to operate the clutch mechanism lon the rear thereby to close the chucks before each work spindle is successively rotated away from they magazine. This lever 1,53 is operated by means of a cam 154 on the cam drum 150, and-said lever operates on the middle spindle directlyV after the plunger 132 has forced a work blank into position in the chuck or grip. On this bracket.151 is also Lpivoted another lever 155, 4designated as the clutchv opening lever, its function being to open or release the grip or chuck to permit the extractor to force Aa lever 153 having a stud or roller effective out the work blank. This lever is also op- .erated from the cam 154 onthe cam drum 150. The upper end of this lever is U- shaped or formed as a crotch, as at 156, to receive a roller 157 carried by a stud rojectin'g from a sleeve 158 bolted to a sli ing rod.159 suitably supported by brackets carrie by the bed of t-he machine, one of which brackets, as 160, is shown, see Fig. 11. Secured to this rod 159 is a dog or'studv 161 having a bronze shoe which is in contact with the clutch mechanism on the rear end of the work spindle. Thus the swinging of the crotch lever- 155 shifts the rod 159 and thereby'the dog 161 to operate on the clutch mechanism carried at the rear end of the work spindles and release the checks or grips when the turret has been revolved or indexed to thatfstation intermediate the saws and the magazine.

On the bracket 151 are securedtwo paral- `lel rods or studs 170 and 171, on which is mounted a slide 172 having a bronze shoe 173 extending into a groove 174 of a spool 175 on the end of t-he extractor or 'extracting tube 35. Projecting from the lower side of this slide 172`is a stud 172a and roller 172b which latter is shifted by means of proper cams 172 and 17219 on cam drum 150 at the proper time, so thatthrough the medium of this slide 172 the extractor tubes 35, one carried by each work spindle, are each successively operated when the work spindles are in position intermediate the saws and the magazine to force out the work blanks after the chuck opening lever 155 has opened the chucks of the work spindles.

From the foregoing it will be observed that immediately after a work blank has been forced by the plunger 132 into a chuck of one of the work spindles the chuck is closed by the lever 153 operating upon the clutch at the rear end of the workspindle and the blank is then rotated by the turret away from the magazine and to a position intermediate such magazine and the upper of first saw. Thereupon the turret is rotated into position to have the first saw cut a diametrical slot. The turret is then rotated into position to have the intenediate saw cut a diametrical slot at an an'gle to the first slot. The work turret is then rotated to have the lower saw cut another diametrical slot at an angleeto the two preceding slots, succeeding which the turret is rotated into position to have the chucks opened by the lever 155, immediately following which, and while the blank is in the position just indicated, intermediate the saws and the magazine, 'the extractortube is operated by the slider172 to extract the blank, whereupon the empty chuck is then rotated by the turret into position to receive another blank in the manner hereinbefore described. A

The clutch mechanism located on the rear end of each spindle is similar to that which is well known,'and therefore a detailed description thereof would seem to be unnecessary, it comprising the usual cone clutch having .a grooved collar 190 and shiftable levers or fingers 191, and which cone clutch is shifted at one time by the lever 153 and at another time by the lever 155. When the grooved collar 190 is shifted toward the right or rear end of the work spindle it spreads the inner ends of the pivotally supported fingers 191 and thereby forces the sleeve 192 surrounding the extractor tube 85 endwise toward the blank carrying chucks, thus forcing the tapered ends Aof such 4chucks into engagement with the chuck cap 31 and closing the chuck upon the blank, i

lthat three blanks are simultaneously operthis being permitted by the slots 193 by means of which the spring jaws are secured to the enlarged portion 28 of the work spindle. At the proper time the shoe 161 of the rod 159, operated by the lever 155, forces the grooved collar 19() in the opposite direction, or toward the chuck. carrying end of the work spindle, thus permitting the 1n ner end of the fingers 191 to close, whereby the spring formed chucks will automatically open and force the sleeve 192 toward the rear end of the spindle. At this time the grooved collar on the rear end ofthe extractor is forced toward the left or chuck end of the spindle, thus operating the eX- tractor and forcing out the blank in @the manner hereinbefore described. A short shaft 200 is secured to the rear end of the turret or cylinder, and on the outer end of this shaft is fastened a disk 201 which holds the extractors in their proper position when the machine is in operation.

The operation of the machine, brieiy, is as follows: A work blank having been received by the middle spindle from the magazine by means ,of the feeding plunger, it is carried, through the medium of the revoluble turret and the fan gear, to the next station, at which point the turret 'is locked. At this station it is not operated upon by the saws. It is ithen revolved to the next station and locked, whereupon the upper saw on the saw slide slots the work blank in the center thereof vertically. On the completion of this operation the cylinder revolves to the third station, where the in-L termediate or center saw operates in the same way as the upper saw to cut a vertical slot, but owing to the revolution of the cylinder to this station the second cut is at an angle to the first cut, and in the present machine is shown at an angle of sixty degrees to such rst cut. The cylinder is then revolved. to the third and last cutting station, where the lower or bottom saw'performs the same operation upon the work blank, this cut being also a vertical one centrally of the blank, but owing to therevolution of the cylinder the cut is at an angle to the second cut and as shown herein it is at an angle of sixty degrees thereto. Thus the surface of the blank has been cut'into six equal parts. The cylinder then revolves to the next station, where the blank chuck is opened and the blank extracted, whereupon the empty chuck is revolved to the next station and adjacent to the magazine, where it is reloaded fro-m the magazine. It is merely necessary to add or remove saws to or from the saw spindles to increase or decrease the number of slots or cuts in the work blanks. It will also be understood that the turret is locked at each indexing thereof. l
