To all whom it may com-em Be it known that we. @SGAR A.. Sm and BHXJAHTX F. Evier-leisen, citizens of the United States, residing at Cleveland? in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for Castellang Nuts, of which the following is a Medion.

This invention relates to means or punch prees for castellating mits, the object of the invention being to provide improved means which will s costellato nues and stand up during the on of this work, and which will pemttheeseof a strong andlasng punch and die.

Ordinarily the ponches used for costell-.iting nuts are very light, usually Width of the slot, and 'm :vw-:M 1t 1s impraelzicable to pch @E noisthe outside toward the center because, owing to the tive narrowne o the and the lightness of its which is in order thajl: @e punch pass into the slot, theponch @d wears ont, and so for as we are aware no practical means have been devised by means of which a heavier punch may be used. Moreover, another serions fault is hhnt ehe die must be only largeenongi in i.: n to accomodate the notr and' yet' contain the necesa-y number of slots, and herefore collapses velv readily. H only-ono slot es inthe die the wearissix times asgreat, and the mit must be revolved imside die, while in the prent impro it is revolved with the die.

One of the objects of the invention is Sie provision of a mechanism of the described by means of which thev powerwill bedeliverwlcletothecntngpointofthe punch.

Another object of the invention lsthe provision of means for locking the punch against endvvise and sidewise, play.

Xnother object of che invention is the pro vision of an improved nut castellating machine haxi -the several novel features hereinbeore re erred to and so organized and combined that a very short downward stroke of the ram, not ondinarily exeecding two inches, will be sucient to punch and clear the punch, rotate the nut blank and lock it accurately in position for the repeated strokes necessary for the punching of the nut. and in. which machine the length of ie punch arm is such that not only may the reinforced punch construction shown be used :md the power of the blow delivered directly in line with the point and closeto it. preventing any tendone;z to spring or to make the stroke uncertain and le eeeve owing. to any lost motion or spring of the tool. but. an almost Hat bottom slot, that is one in which thebottom is practically parallel with the bottomof the nut, is

As a result of practical tests of this improved mechanism the of punching nuts has been v revolutionized. as veil as the cost of so doing very materially lessened. the mechanism having shown itself to be thoroughly practical from a. mechanical standpoint and extremely l in practice. it capable of being operated by nnskiled' help and vet its production is remarkable compared with nut castellat'mgz machines heretofore used. and especially is this so when it is considered4 that. with a stroke not usnaly two inchesthere is snioient force to do the neceary punch ing and suicient time within which to properly and lock the for the snceessire pqnching. operations.

trates the various mem 1 has to do with the numerous improved features thereof, and therefore a brief descriptiofsuchapreonlyisdeemed neces srry in the piment instance.

The punch pres shown comprises the usla!standardovrbaschavnigthe usual power driven wheel 3, timeshat -1 and rain fihereadleandco meanstherebetween and Vthe usual clutch by the shaft. suitably mountzfuponfthe e? press is the punch 10,vvhich is provided with :1 narrow rib-like point l1 the width of the slot to he punched. and :is this point must be narrow to correspond with the size of slotdired it follows that unless such punch is materially reinforced it is very weak and ineilicient. lt is understood. of course, that different sizes of slots require dierent sizes of punches. This punch is formed in such a manner that it widens out considerably just back of the point. thereby a very much stronger punch than the ordinary punch, which is as stated, usuall;r of the same thickness as at the point, and in the prent instance the punch is shown with a rounded tapered surface Iapering from the thickened body 12 toward the point. By means of this construction n very heavy, rigid and reinforced punch is obtained. This punch is carried by a punch holder in the form of an arm 13 pi voted on a Shaft 14, (see Fig. 11), which shaft 14 is supported on a block 14 and the shaft is held in position by caps 14 capable of sliding on bolts b v means of elongated slots so that the bearing caps may be slid apart to permit the pivot or shaft 14 and the punch arm to be removed and replaced. A lock block 15 holds the punch in position sidewise. while a cylindrical lock block 16 and an adjusting screw 1T hold it in endwise. By means of this c vlindrical lock block 16 and adjusting screw 1T, the lock block fitting into `nom-es 1B of the holder, it is found practical to preL vent the punch from workin out of its arm or holder endwise, as the earing of the cylindrical lock block 16 in its cylindrical grooves makes the lock positive while the adjusting screw permits of any desired relation between the punch and this cylindrical block. Ordinarily in the operation of this press the ram thereof would strike on the top of the punch arm at the point a, which would be a considerable distance removed from the working point of the punch, and it was found that the continual action of the power at a point so far back of the actual cutting point had a tendency to bend the point of the punch upward and destroy its usefulness. In the present improvement, therefore, this disadvantage has berm entirely eliminated by the provision of means which enables the power to be applied at approximately the cutting point of the punch. in that Whiletlxe stroke of the ram is still delivered at the point a it is delivered in such a manner that it is transmitted adjacent to the cutting point of the punch, and for this a hardened cylindrical ram extension 19 is provided., this extension being set into the punch holder or arm on an angle. so that while the top of this extension is some distance back from the point of the punch yet the power will be applied to lin the punch Within a short distance from its lao point. This ram extension 19 extends somewhat above the punch carrying arm, so that the ramp-ill alwaysstrike on the end of the extension instead of striking on the top of the punch arm. This ram extension 19 is a loose iitvin the arm and the power rom the ram to a point adjacent to the pointof the punch=` and consequently prevents any bending of the punch during its operation. Moreover, owing to Vthe manner of supporting the punch, whieh makes possible the between the point of the punch and ltsrplrortal I 14 the punch, in horn the of the nut outwardly, travels prac tiallyinalmostastraightlne.

In tothiskickingmeans meansfor the die is also provided, couo an auxiliary index positioning deor locking bolt 44. This bolt is pivoted on a screw pin 45 carried by a U-shaped braeket, (see Figs. 17, 18 and 20), and is into engagement to enter one or the slotsorreesin theindex ringeach time the U is indexed, the bolt engaging that parncuhlar recess or slot which has just been previously engaged by the locking device just described carried by the ram. This bolt is of course uithdravn from the slot to permit the indexing ofthe index ring and die. and this is accomplished by means of a cam 46 rried by a special cam disk 4710 cated on the ily wheel shaft of the ram, and this cam disk cooperates with a lever48 pivoted to the framework of the press, and the lower end of which engag this lock bolt so astoswing it reeoftheslotorm inthe index ring, the lovver end of the lever and ont-er end of the lock bolt ha ifattached thereto a plurality of springs 48' A'which act through the medium of the lever to force the bolt sncceivelv into the slots or recesses of the index ring. Several of these springs are provided so that should one of them break there will be no failure of the bolt to lock the `mdex ring. By this mechanism it will be seen that the cam operating on'the lever just described will swing the bolt from its slot or rece in the index ring to permit the indexing thereof, and that as soon as the index ring has been rotated or indexed, and therewith the die, the Spring described will return or drop the bolt into engagement with the next rem or groove of thendex ring and so hold it in position, and that when the ram descends to operate thepunch' it will be alned and locked by the locking toothshowninFiglandcan-iedbythc ram as hereinbefore described.

For indexing the index and therebyr the die, suitable means 'm providelLxndthis consists in the present instance of an indexing lever 50 'pivoted on a pin-51 carried by the framework of the pm that the indexing lever not only has a 0 movementinavertical plane,b11t alsohasa'slight movement in a plane. this resnlt bem=` n' obtained v ornfnngpivot hele to permit this bee This indexing lever 50 is provided at a pin 5'2 in position to project into one of slots or recesses of the index This dexing lever 50 is actuated he an auxiliar-'v f' member or leverr of which iscuredtoacrcsdeiloftheram, (see Figs. 3 d 20)..andthis ver 53 is provided with 'a cam-projection orface theunderedgggeoftheindexing lever 50, a stud 56 in position to return the lever50toproperin-^ dex positionupward the lever 53 is likewise up# ward and this upwardmovf'. th lever 50 is likewise moved n1V a vertical plane, and owing to` iefat that the indexing pin 5'2- has previomsll4 dropped into a slot or recess of ring the index ring is revolved, in the entiustan owing to the act thatv six are Shown, one-sixth of :1 revolution so as to index the ring and thereby the die, and of course the nut hlanl; carried thereby, which revolves with the die "hen the index ring has been revolved the predetermined distance, the auxiliary index- Ing bolt hereinheore described Will be dropped into position to properly space the index ring and prevent any extensive movement thereof in either direction. During the md and until the completion thereof the straight side of the index pin 52 is maintamed y in contact with the straight side vall of the slot or room into which the pm projects, and this is accomplished by so forming the cam surface at the lower end of the lever 53, as by undercutting it, and by lieveling the lower edge of the lever 50, that the cam surface will have a tendency to hold the lever 50 firmly against the side of the lever 53 while allowing the lever 50 to move acro the lever 53 during its upward travel, a spring plunger 58, (see Figs. 5 and 20), belngprovided to aist in this result. This spring plunger 58 forces the index lever 50 the index ring 29, see Fig. 5. This 1s necessary for the reason that the index pin 52 on the lever 50 will instantly drop into one of the statiom 30 at the proper time and then when the lever 53 comes in contact with the index lever 50, the cammed sections 552 om levers 50 and 53 prevent pin 52 from slipping out of contact with the index stations on cam 29, but before this camming action taks place the spring plunger is the medium that presses the index pin 52 Vo n lever o0 in connection with the index sta- -tlons of index ring 29. This ac'tion of the lever 50is shown plainly in dotted lines in Fig. 5. The Upward movement of the lever 5l! is limited by a` projection or pin 59, (See Flgr20). On the downward stroke of the ram slide the indexing lever 50 is carried downward, cumming the index pin 52 there ofontofitsslotorreofthe index byreasonofthetaperonthehack ofthis pm the out away formation of the Index ring, the ger58bangthusoveroomeatthisme,so thatthepmwillbewithdrawnomits Slotor remand be carried along the face of -t-he index during the remainder of the downward travel of the lever 50 and untilitdropsintothenextslotorressof the ring ready for the next indexlng movement.l and a stop 59 is located in position at the underside of the lever 50, and this stoptogether with stop 59 hereinbefore described form safety stops to prevent the overrunning of the stroke.

- For the purposeof returning the punch to its original potion ready for the next slot1 aspring plunger 60 is provided. (see Figs. 3 and 4). This plunger is supportedhelow theliinrch carrying arm or holder, and the :l

preure of the spring plnnplonger has a -constant bearing upon the underside of this arm duringr its idle and cutting movements. As the ram deends this plunger is forced downward and the spring 61 thereof is compressed` and as the rain upward this spring expands and through the medium of the plunger, lifts the punch carrying armband in this way shifts the' punch from the slot which it has cut and' out of the slot or' thedie and carries punch into position for the next stroke of the ram. The position to which the punch is shifted is controlled by adjusting nuts 62 aud 63 at the bottom of the rod forming the plunger.

In the present improvement the nut blanks are semi-automatilly fed to the die and punch, and for this purpose a magazine T is providedLwhich is bolted to a bracket 71 located in front of the die. It of course, be understood that the magazine is changed for different siz of nut blanks. The nut blanks are held in the magazine by a plate 72 and drop freely into position before a feed rod 73, which is controlled by a band lever T4 pivoted at the front of the machine to a bracket T5 extending therefrom. This feedrodisheldin abushingorguideblock T6 located in' an extensionv of the (see Fig. 6)- The size of the end ofthefeedrodisofeomrariedto fittbe different sizes of holes, and the point is just long enough so that when forced fully into the nutt will clear the punch. As the feed rod is pushed forward by its handlethe free end thereof, which is slottedto -give it a slight spring tension, enters "slghtly into the hole in the lower blank, and aS the blank is puied forward by the `forward movement of the feed rod blankoomes incontactwiththeroundedconer'ofa SPD pressed 73, (See .7: 3 andB ,locatedintherearwallofthemagazine.

After the blank has been punched in the manner hereinbefore described the feed rod is withdrawn by the handle, the tension of lthe slotted end of the feed rod in the blank being sucient to withdraw the blank from between the spring pneed jaws of the holder plate 3:2. As the feed rod is still further withdrawn the back of the castellated blank, which extends slightly above the top of the feed rod, comes into contact with the opposite sharp corner of the plunger 7S, and in this manner the end of the feed rod is withdrawn from the blank and the castellated blank drops out of the way of the blank following it.

From Athe foregoing it. will be observed that by reason of the fact that the punch and the die are notconnected in any way with the ram or the ram slide, or with the power driven shaft, any lost motion of the ram or 'the ram slide or the shaft, or at. the pivotal point of the punch, does not affect the action of the punch, and especially is so because the application of'the power of the ram on the punch is so much closer tothepunchingend ofthepunehthanto Vthe pivotal point. of such punch. Moreover, itv'villalsobeobservedthatowingtothe organization of this machine a twofinch or less stroke of the ram is suicient to efec- 'tively do the work of punching and indexing a blank succeively, to castellate it. In other Words all movements are very short, and consequently can be very rapidly, which shows a decided economy in time and Prod'ton- We as our invention:
