NUT-CASTELLATING MACHINE.

Application filed July 8,

This invention relates to metal working machines, and particularly to nut castellating machines, an object of the invention being to provide an improved machine having automatic'mechanism for feeding nut blanks from an unarranged supply, and sorting the blanks in order to enable them to be fed in position to be operated upon by the tool.

A further object of this invention is to provide an improved machine such as a nut castellating machine wherein means is provided for feeding blanks to a blank holding means from a magazine, and wherein improved mechanism is provided for automatt c'ally sorting the blanks and feeding them to the magazine.

A'further object of this invention is to provide a nut castellating machine wherein mechanism is provided for feeding blanks from an unarranged supply, sorting the blanks and delivering them in proper position and in uniform direction to mechanism adapted to feed the blanks to a blank holder. and wherein the blanks-are, castellated and thereafter ejected from theblank holder, the improved construction being such that all of the operations are automatic and at the same time the mechanism is so organized that the tendency of anyof the parts to jam or otherwise get out of order is greatly minimized.

A further object of this invention is to provide a machine having mechanism for automatically feeding nut blanks from a source of supply, sorting the blanks so that they will be arranged in proper position when fed to the cutting tool and wherein safety means is mechanism inoperative in case of jamming or in the event-that more blanks are fed pended claims,

than can be taken care of in eration of the machine.

Other objects of this invention will appear in the following'description and apreference being had to the accompanying drawings forming a part of this specification wherein like reference characters indicate corresponding parts in the several views, and wherein Fig. 1 is a view illustrating the hopper and the assorting dial mechanism, this view being aside elevation of the construction shown in Fig. 2 takenat the upper part of the mechanism;

Beforev explaining in detail the present improvement and mode of operation thereof, I desire to have it understood that the invention is not limited to the details of construction and arrangement ofparts which are. illustrated in the accompanyingdrawings, since the invention is capable of other embodiments, and that the phraseology which I employ is for the purpose of description and not of limitation.

substantially Heretofore, in machines constructed for the purpose of operating upon nut blanks,

such as for castellating, tapping or otherin a blank operating means, or a magazine,

wise working upon the blanks and wherein a predetermined face of each blank must be positioned toward the cutting tool, it was necessary for the operator to sort by hand the blanks and position them in the proper manner and all in the same direction, either or otherwise in readiness to be fed into position to be operated upon by the tool. This task of sorting or selecting the blanks and placing them in the proper direction reskill of an operator, it has been found in practice that uniform results are not obtained, that the blanks are frequently positioned the wrong way particularly where fed by hand into a magazine.

The foregoing disadvantages are entirely eliminated as a result of the present invention, which does away with all handling of the blanks by the operator, and renders entirely automatic the sorting, arrangement or positioning of the blanks ina uniform direction for operation by the tool. Furthermore, the present invention provides for a the first time automatic operation of themachine.at every stage from thetime the blanks are in unarranged condition in a hopper or other source of supply until the blanks are delivered in finished condition.

In the drawings isillustrated a nut castellating machine embodying my invention,

and this machine is an. improvement over- Patent No. 1,157 ,258, dated October 19, 1915, to Smith and Rindfleisch, and also. an improvement over the co-pending application of Smith and Kinley Serial No. 648,755 filed J une'30, 1923, both said patent and coplending application being assigned to the ational Acme Company, assignee of the.

resent invention. In the machine covered y Patent No. 1,157,258 the nut blanks were sorted or arranged and placed by hand in a magazine, and the blanks were fed successively from the magazine to the punch mechanism by. means of a feed rod operated by a hand lever. In this patent therefore, the entire operations of sorting and feeding the nut blanks was accomplishedby hand, and an operator was required to be in con stant attendance on each machine of this patent. In the machine covered by the aforesaid copending' application the nut blanks were also sorted or arranged or placed by hand in a' -magazine, but automatic mechanism was provided and so timed as to automatically feed the nut blanks successively and at the proper times to the blank holding means, and automatic means was also provided for ejecting or extracting the blanks at the proper times.

As a result of that invention it was possible for one operator to attend to four machines. The present invention however eliminates all handling of the blanks, which are automatically sorted or arranged and fed to the magazine, and it has been found that one operator can attend to at least fifteen machines of the present improved construction.

The machine illustrated in the drawing comprises the usual stand or base 2 for supporting the punch press. The drive or crank shaft 4 is mounted in the upper part of the punch press and is provided with the usual power driven wheel 5, which may be operated by means of a belt 6 connected to the armature shaft of a suitable motor 7, supported by mean's of a bracket 8 connected to the base 2.

To the base of the machine is bolted a bracket 9 having secured at the upper end thereof a housing member 10 in which is supported a shaft 11. .YMounted upon the shaft 11 "is a sprocket 12 which is connected by means of a chain 13 to sprocket 14, se-

cured to the outer end-of the crankshaft 4.

Mounted upon the shaft 11v andsadapted to be connected and disconnected therefrom by suitable clutch mechanism (not shown) is a cam disk 15 which acts upon a stud 16 carried by a swinging feed lever 16. This lever is pivoted at 17 to the member 10 and is connected by means of safety mechanism, indicated in general at 16*, to a link 18. The link 18 is connected by means of a spring plunger 19 to a feedplunge'r 19 which reciprocates horizontally in a channel 20 formed in a magazine supporting bracket or housing 20 mounted upon a pair of extensions or bars 21 bolted to the frame of the machine. To the inner end of the bracket or housing 20 is mounted-in proper position a magazine 22 having at one side.

thereof a vertical feed channel 22 for the nut blanks. At its opposite side the feed channel is provided with a vertical bore in which is housed a spring controlled stripper plunger 23.

'A' link 24 is connected to the swinging lever 16 by means of a pin and slot connection 25. Extending in prolongation of the link 24 is a link 26 which is pivoted thereto at one end and at the opposite end to a swinging lever 27. This lever is connected at 28 to a horizontally reciprocating extractor or ejector member 29, the latter'being' housed at one side of a horizontall ext/ending punch holder 30. The punch liolder 30 a cutting blade carries a punch 31 having normally extending into t v of the nut blank 32 when held in position e center opening within the die 33 by means of holder late 34.. The punch is operated vertically rom the center opening of the blank outwardly through the wall of the blank to castellate the same by means of a vertically reciproeating ram 35 operated in the usual manner from the crank shaft of the machine. The die 33 is indexed after each punching operation by suitable mechanism (not shown) and the punch after being forced by the ram through the crown of the nut blank to form a slot therein is returned to its normal position within the center opening of the blank by means of a spring plunger 36.

Beneath the feed magazine 22and projecting into the horizontal channel 20 are a pair of spring plungers 37. These plungers are suitably supported by means of brackets 38 and are provided with tapered ends 39 normally extending into the path of the blank 32 so that when the blank is fed forwardly from the magazine 22 into the die 33, these plungers will retard the blank sufiiciently to cause it to be seated upon the split end 19 of the feed plunger 19.

A further detailed description of the foregoing mechanism is not herein deemed necessary since the same is fully described in the aforesaid co-pending application and also in the above mentioned patent.

Upon the top of the punch press frame is mounted a bracket 40 which is in the'form of a vertically extending rib provided with an angularly extending flange 41' bolted to the upper part 43 of the machine frame. The forward end of the bracket 40 is provided with an extended bearing 41 extending at right angles thereto, and within this hearing is housed an auxiliary drive shaft 42. Mounted upon a reduced portion 43 of the shaft 42 is a grooved pulley 44 which is frictionally connected to the shaft by means of a fibre collar 45'located between the pulley and the shoulder formed by the reduced part 43, a second fibre collar 46 mounted on the shaft at'the opposite face of the pulley, and a coiled spring 47 held under compression between the fibre collar 46 and lock nuts 48 secured to the outer end of the shaft. The fibre collars 45 and 46 in conjunction with the spring 47 frictionally'bind the pulley 44 to the shaft to a predetermined degree. In case of overload however, this frictional resistance will be overcome thereby permitting the pulley to rotate relatively tothe shaft. The pulley 44 is driven by means of a belt 49 which is connectedto a pulley 50'secured to the outer end of the shaft 11.

On the opposite end of the shaft 42 and bearing against the face of bracket 40 is mounted a drive collar 51 which is keyed to i the shaft 42. Secured by means of pins 52 to a reduced portion of the sleeve 51 is a gear 53, this gear being held against endwise movement by means of a boltand collar 54.

A suitable distance away from the shaft 42 and parallel thereto is a dial shaft 55' which extends through a bore in the bracket 40.

The face of the bracket 40 is also bored to I The gear 58 meshes with the gear 53 on auxiliary drive shaft 42 so that rotation of this shaft will cause the assorting dial or disk 56 to rotate. This disk is provided with a series of projecting pins 60, located in circular arrangement adjacent the periphery of the disk and spaced an equal distance apart.

Bolted at 61 to the punch press frame is a bracket 62, and bolted to this bracket is a hopper 63. This hopper is constructed in two half sections 64 and 65. The sections of the hopper when placedtogether as shown in Fig. 2 form a bowl, and each of these sections are provided with an upwardly and inwardly extending piirved flange portion 66 of similar configuration. The section 64 of the hopper is bolted to the supporting bracket 62 and the two sections are bolted together in spaced relation by means of bolts 67 and suitable spacer washers. The upper ends 68 and 69 of the hopper sections form an upwardly inclined trough and are bolted together in spaced relation by means of bolts 70. The hopper section 64 at one side thereof is provided with an extended bearing 71 in which is housed a shaft 72. The shaft extends through the curved flange 66 of the hopper section 64 and has secured at its inner end a feeding disk 73. This disk is provided with a series of radially extending vanes or paddles 7 4 and it will be noted that the feed disk 73 is housed between the curved flanges 66 of the'hopper sections, the

flange of the section 65 having a convex por-- tion 66 to provide clearance for the disk 73. The vanes 74 of the feed disk are of sufficient length to project substantiallyto-the bottom of the hopper,'=and these vanes operate in the space between the hopper sections.

Adjacent to the outer end of the shaft 72 is mounted a fibre washer 75 which is located adjacent the shoulder formed by the bearing 71. A ratchet wheel 76 is mounted on the shaft 72 against the outer face of the fibre washer 7 5. A second fibre washer 77 is mounted on the shaft against the outer face of the ratchet 76 and the ratchet is held in position between the washers 75 and 77 by means of a spring 78 and lock nuts 79 secured to the end of the shaft 72.

From the foregoing construction the ratchet is mounted on the shaft and clutched to the shaft for rotation therewith by fricclutched from the shaft 72 and will rotate tional tension. In the event that the nut blanks cause the feed disk 73 to jam, or in the event that the feed chute leading from .nut blank thereby permitting the blanks to the hopper is filled with nut blanks, so that no more blanks can be fed at the moment by the feed wheel, the ratchet 76 will be unrelatively thereto.

Bolted at 80 to theouter'face of the dial bracket 40 is an outwardly projecting bracket 81. This bracket at its outer end has a right angle projection 82 which is provided with-a rectangular guide slot 83 (see Figs. 1, 2 and 5). Within this guide slot is housed a gear slide 84, the upper end of which is provided withan elongated slot 85. The slide .is adjusted and secured in adjusted position within the guide slot 83 by means of an adjusting bolt 86 extending through ,the slot '85. The lower end of the gear slide 84 is provided with a suitable bore in which is fastened a reduced end 88 of a stud 87 which is spaced from the slide 84 by means of a collar 89. The stud 87 is provided with a suitable bushing 90 upon which is loosely mounted a gear 91. This gear is in mesh with a gear 92 secured to the crank shaft of the machine. et 14 hereinbefore described is mounted on the crank shaft at the outer side of the gear 92 and is held in position by means of a collar 14 and bolt 14". A collar 93 is mounted upon the stud 87 against the outer face of the gear 91 and is pinned thereto and mounted upon the stud on the outer face of the collar 93 is an eccentric 94 to which is clamped a sleeve 95, the eccentric 94 and sleeve 95 being held in position by means of a collar 96 and bolt 97. Secured to the sleeve 95 is a ratchet feed lever or pawl 98, and the outer end of this pawl is machined at 99 to coact with the teeth of ratchet 76.

Secured to the supportingbracket 62 for the hopper is a bracket or knee 100 in which is suitably housedaspring controlled locking bolt 101 which mates with the teeth of the ratchet 76 and acts'to releasably lock the ratchet in position during the intervals between the feeding movement of the pawl rod 98, or in other words this'bolt 101 holds the ratchet against back lash.- Bolted at 102 to the face of the dial bracket 40 (see Fig. 10) is aspacer or guide strip 103. The upper end of this guide strip is tapered at 104 and partially overlaps the outer face of the assorting dial or disk 56 (see Figs. 3, 4,

. wardly to. the bottom of the hopper-in the space formed between the confronting base portions of the hopper sections 64 and 65. The upper portions-68 and 69 of the hopper sections are formed with ribs 106 and. 107 formingtherebetween a channel 109, the base The sprockmeans of which is formed by the guide strip 103 (see .Fig. 12)-.- This guide channel has a width substantially equal to the length of. a

be fed into' the'channel with the longitudinal axes of the blank extending crosswise into the channel as shown in Figs. 10 and 12. Pivoted at between the. upper portions-of the ribs 106 and107 is a gather strip 108, which is alined with the channel or grooved passage .109 formed by the parts 103, 106' and 107 This gather strip 108 is weighted at larly in Figs' 4 and 10, this channel extending upwardly in prolongation of the chan-' nel 109 formed between the gather strip 108 and theguidestrip 103. guide strip 113 is bolted in spaced relation to the strip 111, the guide strips 111 and 113 beingsecuied to the bracket 40 byimeans of bolts 114 and being suitably spaced apart as shown in Fig. 13. The guidestrip 113 has a greater width than the strip 111 so as to projectover the channel 112, (see-Figs. 3 and 10). 7

Beyond the upper end of the guide strip 113 is pivoted at 115 (See Figs. 3, 6, and 10) .a guide member 116, which is curvedin accordance with the curvature of the assorting dial 56. This guide member 116 as shown particularly in Fig. 6 comprisesan inner guide strip 116 of width similar to the strip 111 and similarly. spaced from the bracket 40 so as to extend in prolongation of,-the guide strip 111. The guide member. 116 also comprises a strip 116 of greater width as in the case of the guide strip 113, and extending in,.pro1on gation. thereof.

The guide member 116 maybe locked in normal position as shown" in full lines in Figs. 3 and 10 by means of a spring plunger 117 (see Fig. 2) adaptedtoproject into a hole provided in the bracket 40. By' ulling the plunger 117 out the guard mem er 116 may be raised to the position shown in dotted lines in Fig. 10. v

Secured to the face of the bracket 40 in a position forwardly-andb'elow the center of the assortingdial or disk 56 'and the lower end of the guard member .116 and iu-alinement with the same is a magazine section 118. Thismagazine section is constructed to form acentral vertical guide channel 119.

for holding a column of nutblanks. This magazine section 118 is connectedwto the magazine 22 by means of a section 120 which is given a quarter-turn or twist so as. to place the nut blanks in a proper direction for feeding into the blank carrier by the feed plunger 19. A return chute 121 (see Figs. 3, 4 and 14) is secured to the bracket and projects from a position substantially below the center of the dial 56 so as to overhang the upper end of the hopper 63.

In the operation of the present improved machine it will be understood that the crank shaft 4 is driven through the drive wheel 5 and belt 6 from the motor 7. The gear 92 (see Fig. 1) will be driven in the direction of the arrow and will drive gear 91 thereby reciprocating the pawl rod 98 through the medium of the eccentric 94. The working end 99 of the pawl rod, coacting with the teeth of ratchet 76 will intermittently rotate the feed disk 73 and thereby impart a rotary step by step movement to the feed vanes 74.

At the same time the sprocket 14, driven by the crank shaft will rotate, through the chain 13, shaft 11 (see Figs. 14 and 17). This shaft not only operates the.cam 15 but also drives pulley thereby driving through the medium of belt 49 and pulley 44, shaft 42. The feeding and assortin dial 56 is rotated from the shaft 42 throug the medium of gears 53 and 58 and dial shaft 55. A supply of nut blanks is placed in the hopper 63 and during the intermittent rotation of the feed disk 73, the feed vanes 74 which operate in the vertical plane of the feed channel 109 formed centrally between the hopper sections (see Fig. 2), will feed the nut blanks forwardly and upwardly beneath the gather strip 108, and between the guide ribs 106, 107, see Figs. 10 and 12. The nut blanks are thus intermittently pushed upwardly and forwardly by the feed vanes and are thus fed forwardly through the runway or guide channel 112. The blanks are kept in place against the face of the bracket 40 (see Fig. 13) by means of upper and lower guide strips 111 and 103, and by means of guide strip 113 which overlaps the end of the nut blanks and is spaced from the face of the bracket 40 a distance equal to the length of the nut blank. ing dial 56 rotates anti-clockwise. or toward the front of the machine, and when the nut blanks reach the top of the runway 112 i (see Fig. 4), and are fed out of the runway, they come into contact with the assorting pins of the feed dial 56. These sorting pins '60 are spaced apart equally a distance slightly greater than the diameter of the crown portion 125 of the nut blanks, (see Figs. Sand 9), and the length of each pin is no greater than the height of the crown portion of the nut blank. Since the nut blanks in the hopper are unsorted, they will be fed up the runway 112, some with the crown 125. facing the bracket 40 (see Fig. 8) and some with the head or hex portion 126 against the face of the bracket'40.

The assort- As'shown at A in Figs. 4, 8 and 9, those blanks which are fed to the assorting dial 56 with the crown 125 toward the face of the bracket 40 and also toward the face of the assorting dial, will pass between the pins 60 and drop into the return chute 121 and will be returned to the hopper 63. Those blanks however which are fed with the head or hex portion 126 toward the face of the bracket 40 and the face of the assorting dial 56, will be held on the pins 60, as shown at B in Figs. 4, 8 and 9. It has been found in practice that the nut blanks as they travel out of the runway 112 will be swung by gravity into such position that the corners of the hex portion of the nut blanks will be received upon the pins 60, as shown in Figs. 4 and 9. The blanks are carried by the assorting dial 56 from the runway 112 to the vertical guide channel 119 of the magazine section 118, and

it will be seen that only those blanks will be 1 fed into the magazine which face in the same direction, or which face in the present machine with the hex portions against the face of the assorting dial 56. All nut blanks therefore which are carried up the runway 112 to the dial with the crown portions against the face of the feed dial will be sorted out by virtue of the pins 60 and will be returned to the hopper 63.

It will be noted that the guard. member 116 holds the nut blanks in proper position on the pins 60 as the blanks are carried around by the dial to the magazine 118. The. strip 116*" of this guard member (see Fig. 4) i is in position to prevent the hex portion of the nut blank turning on the pins 60, and the outer strip 116 of this guard member (see Figs. 3 and 10) overlapping the crown of the blanks and holding them in position on the pins against endwise movement. This guard member 116 is pivotally hung at 115 so that it can be raised to remove any imperfect nut blanks that might feed to the magazine and tend to clog it.

It will be noted that the assorting dial 56 is friction driven by means of the friction fibre collars 45 and 46, and spring 47 (see Figs. 2 and 6), so that in case the magazine 118 becomes full so that no further blanks at the moment can be fed into the channel 119, the dial 56 will stop rotating and remain neutral since the frictional tension between the pulley 44 and shaft 42 will be overcome.

It will also be noted that the feed disk 73 in the hopper is provided with a frictional drive by means of friction fibre discs 75 and 77 and spring 78 sothat when the sort ing dial 56 stops rotating, and no further nut blanks can be fed into the runway 112, the frictional tension between the shaft 72 and ratchet 76 will be overcome thereby causing the disk 73 and its feed vanes 74 to remain neutral. Since the gather strip 108 .blank and positively extract is pivotally hung at 107 it may be raised when desired either to remove defective nut blanks or in case of jamming. It will be seen therefore that all of the nut blanks by means of the assorting mechanism will be fed to the magazine section 118 with the crown portions facing in the same direction. All of the blanks will be given a quarter turn when passing through themagazine section 120 and will thus be delivered to the main magazine 22 with the crown portions all facing toward the die 33 and the punching mechanism. 1

The operation of the punch and'ejcctor mechanism whereby the nut blanks are fed from the magazine 22 into the blank carrier 34, and ejected therefrom after being castellated is as follows:

It will be understood that the mechanism is so timed by means of the cam disk 15 that upon the upward stroke of the ram 35, which operates against the punch in the manner described in the aforesaid Patent No. 1,157,- 258, the feed plunger 19 through its actuating mechanism carries a nut blank 130 into the blank carrier 34 and die After the ram has been reciprocated so as to cause the punch 31 to punch the desired number of slots in the blank, the ejector plunger 29 is operated through the lever 27 to eject the finished nut blank.

It will be understood that by means of the cam 15 operatingupon the ram roller 16*,

the lever 16 will be shifted forwardly there.

by shifting the link 18 forwardly and through the spring plunger connection '19 shifting the plunger 19 forwardiv to cause the split end 19 of the plunger to enter the bore of the nut blank. is carried out of the channel 2( 51'see Fig.

15) will engage the rear tapered fare of tension plunger 23 which will retard the blanks sufficiently to permit it to be fullv seated upon the end of the feed plunger 19. The tapered ends 39 of the tension nlungers 37 will also act to retard the blank to permit it to be properly seated on the feed plunger 19. The interval during which the cam roller 16 travels on the annular face of the cam disk 15 is occupied to complete the punching of the blank. the blank being indexed after each stroke of the punch. and after the final stroke of the punch the lever 16 will be swung rearwardlv thereby causing the plunger 19 to be shifted rearwardlyr away from the die 33. At this time the .lever 1,6 will shift the links 24 and 26 rearwardlv therebv the ejector lever 27 to force the ejector 29 forwardly against the nut it from the die 33"and the blank carrier 34.

From the foregoing it will be seen that vthe present improved mechanism eliminates entirely the necessity of the operator handling the nut blanks at any stage in the The nut blank as itfore and in fact 15 machines of the present construction may be controlled by a single operator, thus reducing to a considerable degree the labor cost and the cost of production, and at the same time enabling the machines to be operated continuously and at longer sustained intervals without stopping.
