WILLIAM C. STEWART, 0F LYNN, MASSACHUSETTS, 'ASSIGNOIQ BY MESNE ASSIGN- MENTS, TO THOMAS G. PLANT, 0F BOSTON, MASSACHUSETTS.

To aZZQwhom 'it may concern:

1Q is a plan of the main parts shown in Fig. 8; Fig. 11 isa front elevation of the mechanism shown in Fig. 10, omitting the clutch; Fig. -12' isa detail in section on line 12-12 of F ig. 11, looking-in the direction of the'arrows; Fig. 13 is a side elevation showin-g the nail carrier and the means 4for operatingthe carrier from a moving part of the-machine; and Fig. 14`is a section on line 14-14 of Fig. 13.

In the embodiment of the invention selected for illustration, and referring more particularly to Figsrl to 5 inclusive, lis a nail hopper-supported on a bracket A of the.

frame'B (Fig. 8) and provided with a rotating nail elevatingwheel 2 having a bearing on the lhopper and carrying buckets for elevating nails inthe usual manner from the mass in the lower' partof the hopper, and delivering them upon a shelf or table 3 with# 'in the hopper. The table 3- guides the nails to the upper end of a roller raceway comprising parallel `rolls 4, 4, which extend within the hopper, and are-mounted in suit- 'T he nail gear', at its rear, which is driven bya worm 6 (Fig. 2) in turn driven by friction belting 7, actuated, as may be convenient, from any running part of the machine, for instance, the sheave 7 (Figs. 8 and 10). Extending throughl gear 5, is a shaft 8., on the end of which, within the hopper, is mounted a bevel gear 9, the shaft 8' being rotated by means of a friction drive 1 0, driven preferably from the same source of powerv as the 'friction drive 7. The bevel gear 9 meshes with a bevel gear 11 (Fig. 5) on-the upper end of 011e of the rollers 4, and each of the rollers carries'a pinion 12 which pinions mesh with each other.'V Thus the rollers are each rotatedoutwardly in .opposite directions (see th; fmmws in'Fig. 4). -The bearings for the rollers 4, 4 are snel: (see Figs. 2 ,and 5) that. there is space leftv between Ll.'m.sulicient for -nails delivered to the table4 3 with their points down to extend between the rollers but be supported thereon by means of their. heads. Nails are fed to the hopper 1 sov through the chute 13, which chute extends down into the hopper at one side (Fig. 2), leaving an opening at its basethrough which nails arev fed into the base of the hopper by the weight of the nails above them 1n the chute. The opening at the base of the chute isof such size' as to always maintain the mass of nails in the hopper proper at a height relatively. to the nail buckets on the rotating wheel 2, so that the buckets may always be supplied with a sufficient quantity of nails, and yet the'congestion caused by a great mass of nails in the hopper will be avoided. In order to vary the amount of this yopening at the base of the chute 13, as may be necessary, there is provided lan adjustable gate 14. This 'gate (Figs. 1 and 2) is mounted within a Slot 15, in the side of the hopper, and may be 'raised and lowered pressed stop-pin 17 .carried by the handlein in saidslot by the handle 16 and looked in any desired-position by placing the spring any one of the holes 18 in the side of the hopper. Thus the flow of the nailsfrom the chute to the hopper and the height of the nails adjacent the buckets may be regulated as may be necessary. AAs the bucket wheel 2 *rotates it will constantly deliverto the table- 3, and to the roller raceway, a series of nails which will slide down the-rollers by gravity to the rollers so as to be delivered from the hopper, tlieyovill, nevertheless, in many in stances remain supported by the rollers and will slide down on top of vthe rollers until they are prevented from further movement by' the front wall of the hopper 1. It is,

therefore, desirable that some means be provided to relieve the roller raceway of the congestion of nails which will form 'at the frontwall of the hopper and to keep the lower ends of the rollers clear of improperly positioned nails so that nails correctly delivered t0 the rollers may pass onthrough the front wall of the hopper and to tlieex- .terior -raceway 19.l To accomplish this object, in the illustrative embodiment of the invention, the rollers 4, 4 are provided adjacent to vfront wall of the hopper with a seriesI of longitudinal depressions 20, forming a ribbed or corrugated surface shown most clearly in Fig. 8. Extending over this' corrugated surface and carried by a removable cover plate 21 mounted, by means of the screw clamp 21a, in the front wall of the hopper, is a leaf-spring 2 2, of such width as to effectively covervthe space' between the rollers (see Fig. 4) and of such heightabove vas will be hereinafterA described.

the rollers that in order to pass under it the nails must dip down under it. The depressions 20l permit the heads of all correctly po sitioned nails to drop below the plane ofthe upper surface of the rollers and' thus pass under the spring 22. The upper end of the spring 22'terminates short o the upper end ofthe corrugated surface. may be seen by reference to Fig. 4, that'the heads of all correctly positioned nails will `slide into the depressions 20 and will rest- It is obvious. as'

beneath thevspring 22 upon the ribs on the rollers, and that with the rollers 4, 4 rotating in the direction of the arrows in said figure, thenails willbeconstantly worked upwardly against the .under side of the spring-22. The spring 22, however',vl acts. as a yielding cover plate to prevent Athe nails Vbeing fed out from between the rollers by the action of the corrugated surfaces-. The nails,

by this device, are constantly agitated and are thus separated and aided in their proga ress down the raceway. It is also obvious that-instead of dropping between the rollers it extends transversely thereof, and remains supported by the rollers until it slides against the spring 22', it will either fail 'to force -itself under the spring and will therefore drop from the raceway, .or if it doeslget that if a nail is delivered tothe racewayso v l under the spring the ribs upon the rollers f will act as teeth to engage the nail and feed it to one side 'or the other and thus ofi o f the rollers and back into the hopper. A similar action occurs with all-improperly 'positioned nails. It is seen that Vthe corrugated `portion of the rollers thus performs two functions, irst, to agitate the nails whereby they are separatedl so that they may be fed singly and smoothly tothe exterior raceway; and,

second, to act as a' nail deflector to deflect from the raceway nails which have been iin- -v properly placed thereon.

Referring now 'to'Figs rior raceway 19, 1s of usual construction,

namely consisting of a pair of parallel bars suitably spaced apart and between which the 6 and 7 the extej nail extends, the nail being vsupported on said bars by means of its head. The raceway 19 is alsov provided withthe usual cover plate 23. The raceway 19 is preferably remov- -able from the machine and is held in place` by means of a spring catch. 24a upon. a bracket 24 extending from the nail hopper. The upper end of the raceway has a bearing in the portion of the hopper formingabearing for the lower end of the roller raceway vand its lower end has a vbearing upon the support for the nail-receiving cylinder 26,

rt' has been found that when operating it at.` a high rate of speed theprogress of the nails down the 'raceway by gravity alone is not fast enough toproperlysup ly the nail receiver. To overcome this di cultv and '.efecty a lao properdelivery of the nails the vfollowing means are preferably employed. One 'of 'the side plates of the raceway'19 is .cut away toward its lower Vend to form an openingl at 27 (see dotted lines Fig. 6) so that the nails resting 1n the slot of the raceway are exposed. Operating. inthisslot isa springe finger 28 which; for convenience, mayl'be termed an accelerator finger The finger 2S is mounted upon one end'of an arm 29 which has an extension 3() provided with a.

33 is a coiled spring 34 one end of .which is,

secured .to the s ide of the .race'way, ,the other end of which bears uponthe lower end of the lever 32 in such manner that the lever is maintained in position. so thatthe accelerator nger'QS is normally in its retracted position, or at its greatest distance-from the delivery end of the raceway. Means hereinafter described are provided to oscillate the lever 32 uponfitsI carrying'stud, so that the accelerator finger 28 is given a reciprocatory motion longitudinally o'f the raceway, heilig guided in its movement by the pin and slot connection 30, 31. The movement ofthe leverBQ is sii'h that the accelerator finger 28 is vcarried on its backward movement (to` the right Fig. 7) beyond, say, the fourth or fifth. n'ail from4 the delivery end of the racewav, so that with its' forward '-mo'vement all of the nails .ahead of Vit are carried forward from `the end ofl thel raceway, uickly and sharply. The finger 28 acts. therefore', as an acceleratorto speed the endmost nails in the i'aceway intol position for rapid deliveryto the nail receiver. It should be particularlyY noted'that the accelerator finger 28 is, of itself. yieldmg. invention 'it is formed of a light leaf spring.

This lis for the-reasou-that the movement-of the nails at the delivery end ofthe raceway should be accelerated by a .very light pulshA ing action so as to eliminate crowding and punming. against thtl nail lseparating devices lt has been found iu practice-that if a stift vfinger is used. to 'engage andlv accelerate the nails, even though mmh finger be lightly spring pressed, the weight of. the metal alone, as the finger ismoved forward, is sufficient to cause a jamming ofthe nails and prevent a proper separation thereof-from,

the ra-ceway. lilith. however, an accelerator finger arranged so that the yield is'witllm itself, and-'such yield is therefore unimpeded by any intervei'iing part. when it becomes necessary for the. finger to move backwardly during its forward movement to prevent a jamming of the nails. such liamming is effectively overcome. .Those skilled in the art In the illustrative embodiment of the.

plate is' spaced at- -su'fiicieiit. distance from will understand the effectiveness of such an accelerator, as above described, without further dilation upon its action and advantages.

In the embodiment'- of'the invention selected 'foi-.illustrative pu ses, the nai'l as sorting mechanism hereto ore described hasvvbeen vshown as combined with means ifor .delivering a group or gan of nails tothe 4nail driving. devices of aieeling machine,

for instance, such a machine as is shown. in United States vatent lto `Raymond 317,199, Mayv 5, 1885, W ierein nails aredelivered -as a gaig to a distributor which."arran sthe nails'- in proper orderfo'r insertiol'na l as is .well known 'to those skilled .inpthe' art. It should v.he distinctly understood, however,

'that the type fof, heeling machine shown 'in the Raymond patent above referredto isinot the only'type or kind of machine; with which the invention can be used. A Adescription 0f the preferred form of nail delivering mechanism lwill now be given. .'.Referring4 now to Figs. 6 to 10 -of the within a hollow cylindrical Support 35 in turn supported .upon a bracketl C carried -by the l frame B. The support 35 is-provided with a yoke 3T which supports the upperl end of a stud 3S upon which the, nail receiving cylinder 26 is rotatively mounted. The lower end of the stud 38 is Asupported in a bottom plate 36 (Fig. 6) secured to the support'. The hollow c 'vlinder is provided with an opening vin its periphery, .nrwhich the lower end of the exterior racewa'y '19v is adapted to' rest. To. aid in. supporting i't in position the raceway carries a slotted bracket 19b engaging a pin i9? on' the support 35. rlhis 4lower end of the racewa'y 19 is so formed (see Fig. l7) that tlie nails in the raceway'are prevented from "sliding directly out y.of its end but are Aforced to be delivered sidewise,therefrom. In'order to obtain this sidewise deliveryof the 'nails the .illustrative embodiment of the' invention, .the 'nail receiving. cylinder 26 1s .mounted `which extends from oneof the side rails of the race-way, across the end of the racew-ay opening and over thenail.cylinder26.- This the end of the other siderail of the raceway so that nails may be'passed between the plate 3S) and' the raceway end. T'o retain the descending'nails vin proper vertical relation to the nail receiver 26 for' eflieiei'it/delivery thereto. asecorld late 39,"siinil-ar "tothe plate '39. extends .rom-the raceway below lthe plate Bflandinto a circumferential slot im. in the nail'receiver (seeFig. 6).. The nails iu resting against these plates are supl ported preferably at substantially right angles to the surface of the i'aceway. lu order to retain the endmost nail at the de livery end of the raceway and against the plates 39 and39a a---pair of pins 40 (Fig. T)

50 Eway past the retainin -may be provided, extending through one of .the side-rails of the raceway andV 'pressed forward by means of aI leaf-spring 41 moulited ou the raceway. The pins 40 thus ynoriinallyfclose the transversely arranged exit from the raceway.

As these pins 40 are spring pressed, if any force is exerted upon the endmost nail in a sidewisev direction, the pins are readily forced back against the spring 4l to such an extent that the nail' may be delivered. v Many heeling machines are designed to support the shoe in themachine in such position that nails must be driven upwardly to attach theheel to' the shoe and in such cases vif nails are assprted and delivered to a raceway, as is customary, with their points down, itis necessaryto reverse them before theynare driven. In other 'heeling machines thenails are driven downwardly into-the heel, either to load the heel .or to attach the heel to the shoe. In v`the present instance,

y the parts of the machine are preferablyso .arranged that nails are selected directly from the raceway with their points down and are maintained in this position throughi out the distributing and driving'operations,

that is, there is no reversal of the nails after they are delivered from the nail raceway. To the accomplishmentv of this object, in

` the illustrated embodiment of the invention,

the nail receiving cylinder '26 has been placed immediately. adjacent to, the deliv- .ery end of the raceway 19 and with its axis 'successive recesses in alinement with the endof' they Opening in the raceway, throughA means hereafter to be described, a series of nails are forced by the accelerator 28-for- Wardly toward suchrecesses so that the endmost'nail rests in the recess which has been placedv at the end of the raceway (see Fig.

.7 Rotation of the cylinder will cause successive recesses 42 to piclroff successive nails and deliver them si'dewise out of the racepins 40 when such pins are used. The lio low cylinder 35 prevents such selected nails from falling out- Wardly from the receiving recesses 42.

` ,It has been common heretofore to. rotate a nail cylinder for receiving a group or gang of nails by means of pawl and ratchet mechanism, but`when such driving gear is used it is necessary to provide some means to prevent overthron7 of the'rotating cylinder soithat eachv of' its nail receiving recesses may be properly alined with the opening in the raceway, and it is also necessary to provide separate devices for locking the `rotating ratchet against backward motion.

Such meansto rotate the nail receiving cylinder have been improved by providingv devices whiich insure a positive rotation of the vices will now be described. v

"A clutch of the Wellr known Horton type .is indicated (in Figs. 8 and 10) at 43 V mounted on a shaft 44' which shaft is driven by a belt engaging the fast and loose pulleys 44a and 44D. The belt is shifted from the fast to the loose pulley by hand, to allow of hand manipulatiomand the clutch ,is preferf .ably thrown in and out by operation of the Fast on the shaft 44 is a sleeve.

machine. 45 (FigsI 10 and 11,) proif'idedwith one or more spring pressed pins 46 which engage a second sleeve 47 on the shaft 44. The second sleeve 47 is provided with a pair of longitudinal slots 48. A third sleeve 49 on the shaft 44 is pro-vided with a pair of longitudinal lugs 50 at the end adjacent the sleeve 47, which' extend into the slots 48 on said' sleeve, said slots'acting as guideways for the lugs in longitudinal movement of the sleeve 49 upon theshaft. The sleeve 49 is provided with a cam groove 51 'and -with a4 worm 52. The bracket C in which the shaft 44 is journaled is providedwith an auxiliary bearing which supports a roller-stud 54 (Fig. 6) with which the worm 52 is adapted to mesh. With suoli a construction, it is evident that as the worm 52 is rotated in one direction (as illustrated, toward the operative, viewing Fig. 11) the longitudinal y movement to the right, controlled by the cam 5l. is such that the threads of the worm turn idlybetween the teeth of the 'gear 55 and do not rotate said gear.- On the other hand the longitudinal movement of the worm to the left, while still rotating in the same directioin will operate to turn the gear 55 (in the direction of the arrow, Fig. 7 with greater speed than would be-possible if no longitudinal movement were given'to the sleeve 49. Thus the nail-receiving cylinder 26 is positively driven with a step-bystep motion by means constantly in working engagement'the feeding movement being accelerated by the construction of the driving devices so that the suddenv start and stop of the receiverv incidental to receiving, nails singly from the raceway at high speed` is controlled and the receiver locked by its f actuating means. Over-running of thev nail receivin grooves in the receiver, so that'a .nail .cou d not be properly .delivered to its receiving reces'sfer shipping of nails is prevented. The, connection between the sleeves and 47, by means o1 the-spring pressed pms 46, acts as a safety device to dlsconnect the worm 52 from the shaft 44 should the nail cylinder 26 or other moving parts be-V One 4wall of 'the cam groove 51 in the -sleeve 49 extendsjslightly above thesurface o f the sleeve and .this extending wall is pro vided with a cam surface 56 Fig. 11).

' Adapted to engage this cam su face (see er 57 on the lower arm 'of a Fig. 10) lis a. rol bell crank lever 58, pivotally mounted upon a stud 59, which is rotatively mounted upon a stud 60, extendin from the bracket C. The upper arm61 o the bell crank lever 58 is adaptedto engage with the lever 32 which i carries' the acceleratorfinger 28 (Figs. A64 and 7). The'roller 57 is normally pressed toward thecam 56 by means of a sprmg 62'extending between a lug on the .bell crank lever 58 and a lug on an' extension 59'l formed onthe supporting stud 59. The stud59' is normally maintained in4 position for the roller 57 to engage the cam- 56 by means 'of a spring pressed pin 63 mounted in a socket on the bracket C and adapted to engage a recess '64 in the extension 59?. The stud 59 carryin the bell crank lever 58 is rotatively mounte on the stud 60 sothat the upper arm .61 of the bell crank may be: withdrawnfrom engagement' withthe lever 32 of the accelerator to permit ready removal of the raceway 19 from the machine. 'With such a construction it is seen that with each rotation of thel 'sleeve .49 and therefore with each step-bystep movement of the. nail receiving cylinder 26 the accelerator-linger28fis reciprocated to engage behind a number of endmost nails in the raceway 19 and then to force them quickly forward to be engaged, one by one,

by the nail-receiving recesses 42 and re' moved from the raceway. The reason for provldm an accelerator to speed the lowerlnost nal `s 1n the raceway forward toward the nail-receiving cylinder,l is, that if the vnails were allowed to slide down the race- Way by gravity alone they would not be supplied fast enough to fill every recess in the cylinder as it rotates past the delivery end of the rat-exray. Means is thus provided to fill cach successive recess -l2 of the cylinlprovided with a series of openings 66 (shown in dotted lines in Fig. 7) which normally are out of register .with the nail-receiving recess 42 and are so maintained by means of a spring 67 secured .at one end to the cover plate' 65 and at its other end to the cylinder 26, and extending within la recess in the cylinder. The cover plate is maintained in position with its holes 66 between the nail-receiving recesses 42 by means of a pin 65iL extending from the cylinder 26 and into a slot 65" in the cover plate. The engagement of the ends of the slot with. the pin limitsthe movement of the cover plate in either direction around the stud 38. cover plate 65 is alsoprovided around its A periphery with a serie', of lugs or-'teeth 65 (see dotted lines Fig.- 7), one for each of the ,series of holes 68 (Fig. 6)' which coincide fromwith the nail-receiving recess 42 and each of these holes 68 depends a coiled wire distributing tube. 69 as is usual in heeling machines. uting tubes project into a distributer platek 70 (Fig. 8) which is in the form of a removable block having therein a series of holes corresponding in number to the number of nails it is deslred to drive in a heel.v These holes are arranged ',in the form of a 'horseshoe, as is customary7 so that the nails may be driven evenly within the outer periphery of the heel. Below the distributer plate 70 is mounted a nail carrier-..71 upon an arm 72 adapted to swin'gabout a stud 73 on the main frame and move the nail carrier from a position beneath' the distributer plate to a position beneath' the nail driving devices. One form of means for thus moving the nail carrier from a moving part of the machine is shown in Figs. and 14, wherein B is or may be part' of the 'machine supporting fran'ie'carrying the stud 73 011 whichis the hub 150 of the carrier arm72.- The hub 150 has a gear segment 151, the teeth of which mesh with. the teeth 'ofa on the upright shaft 153, the lower end of which carries a gear 154 which is engaged by a segment 155 formed on one end of a lever-.156 pivoted at 157 to the main frame. Said lever 156 carries at its other' end a pin or roll which is held in engagement with an actuating cam 159 by means of a spring 160, one end of-Which is connected to the end of the lever 156 at 161 and the other end toa.

fixed part of the frame, as will be clear.. Thecam 159 is secured to thec'ounter shaft 162 mounted in the main frame. and driven The lower end of. these distribA The recesses 42 for a'purpose to be hereinafter gear 152. mounted from the raceway may be delivered from the cylinder as a group or gang through the distributing block 70 and into the nail carrier 7l, means is provided for actuating the cover plate 65 to bring its holes 66 beneath the lower ends of the nail recesses 42 just at" lthe time when the'nail carrier has reached its position beneath the distributer block. The preferred form of suchineans comprises a spring pressed pin 74 (Fig. 8) mounted onthe nail-carrier arm 7 2, which pin is adapteid to engage, on the movement1 of said arm to bring the nail carrier under the nail disl tributeigi he. dependingv arm 75 of' a small bell ciant lever mounted on a stud 76 extendini; from the bracket which suppoits the nail distliibuter 70. To the other arm 77 of this si al l'vbell crank lever-there is pivoted a rod 7 tithe other end of which in turn is ltoj, one end of a lever 79 pivotally Vupon a stud SO on the bracket C. end of the lever 79 is so formed as to be ladapted to engage the outer end vSl of a lever lplivotally mounted on the bottom plate 7). The other end 82 of this lever i, tadapted to project between and engage the teeth 65C on the periphery7 of the cover plate 65. The end S2 of this lever is normally i with the teeth 65c by meansv of a coiled spring 83 arranged to normally force said end outwardly, stop pinv St limits the outward in vement of said end of the lever. A spring glia maintainsthe bell crank lever arm- 7 5 n finally in positon tobe engaged by the pijn 74. The rod 78 may be pro-vided `with a thri buckle 781 so that adjustment may be ma i e f or wearer for other purposes as may `|desired. lith such a construction whenl'the carrier arm 72 is swung/ to lorinpthe carrier 7l beneath the distributer 7d the spring pressed pin 74 engages the arin 75y of the bell crank lever and draws the rod 78 downwardly thus actuating the lever 79 to engage the outer end of the lever 8].-82 and force its inner end into engage- 4ment with oneof the teeth 65C so as Yto roy tate the' cover plate 65 about the stud 38 and bring its holesl 66 beneath the nail-receiving recesses 42.

`The rotation of the shaft 44; is initially startedpreferably by means of the follovv ing mechanism: After the nail 'carrier 7 1 has received a gang of nails from ,the nail cylinder by actuation of the 'cover' plate 65,l

as above described, it is moved, as is cus- ,toinary in heeling machines',..from its position beneath the distributer to alposition beneath the nailing devices. On the beginning of the-movement 'of the carrier 71 from l naintained out of engagement' the distributer' aspring pressed pin 85 (Fig.

8) mounted' in the carrier arm 72 engages` the lower end 86 of a small bell crank lever pivoted at 87 on the bracket which support." the distributer. lTo the other arm 88 of this small bell crank is pivoted the lower end of a rod 89 the upper end of which is in turn pivoted to a crank 90 on a rock shaft 9i mounted in bearings upon the bracket (Fig. l0). The rock shaft 91 also carries a crank arm 92 adapted to engage Yin a recess at one end of a trip-lever 93 pivoted at 94e on one of the bearings of the shaft 44. The

rock shaft 91 also carries a stop arm 95 ing said crank arm and theother endI held from movement in a lug 97* the bracket The rod89 may alsoI be provided with a turn buckle 89a if desiied. Vith such a' construction it is readily rseen that as the carrier arm '72 moves the nail carrier Il away from the distributer 70 the pin 85 willl movetlie bell crank Sti-88 in such a direction as to pull downwardly on the rod 89 andthereby move the crank arm 92, and the stop arm 95, away from'the lever respective'y.

as to' have about its periphery a sufficient U nun/iber of nail recesses 42 to accommodate the" greatest number ofl nails that may be ut/llized in nailing a heel ofany size upon a shoe. In the present instance the cylinder 26 has been shown with fourteenv such nail recesses. It is obvious, however, that in different sizes of" shoes a different number of nailswill .be required as there is more or less space in each-to insert the nails. `:Thus in small sizes or in the heels of ladies shoes itV is desirable to use' only five nails, Whereas on the larger sizes, and particularly in' the larger sizes of mens shoes, it is desirable to use as many as ythirteen nails. It is therefore seen that it is highly desirable that the izo machine be provided with means forpiey determining lthe number, of nails which shall l from said cylinder tothe driving mechan ism of the machine as may lbe necessary for the particular size of heel being operated on).

To the accomplishment of this objectthere'" 85 on the rock shaft 91, having one end' enga'othas been provided on the machine what may he termed a counting mechanism, which is under control of the operative as to its setting. and may be set to deliver any desired number of nails up to the full capacity of the mul-receiving cylinder. Although there are fourteen nail recesses in the illustrative nail-receiving cylinder it is obvious that one of them will always b e atv theI end of the raceway when the cover plate is moved to deliver the nails as a gang, and, therefore, as thenail in the raceway is held therein by its head it cannot'be delivered to the cylinder. .lf such delivery could 'take place it would also allow the ne-xt nail in the raceway to immediately fall intosaid recessand slip into the distributer on top of thefirst nail, and so on, with the resultl that the delivery of nails` would become choked. T here is, therefore, av blank in the bottom plate 36 at the raceway end-.and thus the capacity of theA nail receiving cylinder shown for illustrative purposes is thirteen nails.

The lever'93 above referred to is used in connection with the mechanism for counting varying predetermined numbers of nails into -the n-ail cylinder 26. The preferred construction of this mechanism and its connection with the lever 93 will now be described. e

Mounted on a hollow stud 97 (Fig. 12) extending transversely through the brackets C and at right angles to the axis of the shaft 44 is apinion 98, which may be termed .a counting wheel. This pinion is provided with a series of circumferentially arranged holes 99 (Fig. 9). lithin the hollow stud 97 extends a pin 100 having on its end adjacent tov pinion 98 an arm 101 which extends from the pin 100 radially of the pinion 9.8 'and is provided on its surface, next the surface of the pinion, with a projection or pin 102 adapted to enter any one of the series of holes 99 and thus lock the -arm and pinion together. The-other end of the pin 100 is provided with a disk 103 (Figs. 10 to 12) having marked'thereon a series of figures, which disk may be turned by'means of a thumb-nnt 104 to bring any on-e of the figures in the series opposite an index 105 in the bracket' Cm The arm 101 is normallyT maintained with its pin 102 in engagement with onel of the `holes 99 by means of an expansion spring 10G having bearings between the disk 103 and lthe bracket C but said pin 102 may be easily disengaged from the hole in which it happens to be by pressing inwardly on the disk 103` thereby compressing the spring 106 and sliding the pin^100through the hollow` stud 97. Encircling the hollow stud 97 is a coiled spring 107, having one end secured to the` stud and its otherend secured to the bracket C so that when the pinion. 98 1s turned in one direct-ion .it tends to constantly wind up the spring 107.

.'f nthe sleeve 49 which carries`the worn-l 52 is a circumferential rib 108 provided with a broken away portion so that lil does""11ot lextend wholly around the sleeve. The pinion 98 is so located beneath the` shaft 14 that when the sleeve 49'rotates. t-he rib 108 engages between the teeth of the pinion and in themovement 'of the sleeve to the left (in Fig. 1'1),operates to .turn the pinion in a contra-clockwise direction. The cut out portion of the rib 108 is so placed that on the -inovement of the sleeve 49 to the righty (in Fig. 11) the teethof pinion 98 are not engaged, and no movement is therefore' given to 'the pinion, but during this movementl of the sleeve 49 to the right the rib 108 is moved to a position 'Where it can, and does, engage the next tooth of the pinion at the beginning of the next movement of the sleeve 49 to the left. Thus as 'long as the sleeve i9 continues its reciprocations the pinion 9S will be given'repeated impulses and will be turned step byl step. Thev pinion 98 is prevented from turning backward, through the 'force exerted by the spring 107, during the ytime that. the cntaway portion of the rib 108 is moving past it. by means of a pawl 109 pivotally mounted upon' the bracket C (Figs. 9 and 11) which is maintained in engagement with the teeth of the pinion by a loop-spring 110 having one end 'engaging the pawl and its other end mounted in the bracket 'C. It is obvious that if, after the pinion 98 has been rotated as described, the pawl 109 is moved from engagenient with the pinion 98 the then tensioned spring 10T will operate to immediately tu-rn the pinion backward the entire distance which it ha`A been moved forward. To engage and disengage pawl 109' from the pinion 98 is one of the functions of Athe lever 93 heretofore referred to. To the end'of lever 93 opposite that engaged b v the crank arm 98 is pivoted a rod 111 which at its other end is provided with a pin 112 adaptedA to engage a pin '1123 extending from the pawl 109. The pins 112 and 113 are normally maintained ont of engagement, so that the spring 110 may actto keep the pawl 109 in engagement with the teeth of the pinion 98, b v means of a coiled ion spring 114 surrounding the-rod 111 having one end secured to the rod itself and its other end secured .to a loose collar on the rod, which collar is prevented froml movement in a direction toward the lever 03 by means of a stop lug 116 extending from the bracket C (Fig. 11). The end of the rod 111 extends across the face of the pinion 98 in' such osition that as the pinion rotates the en of the rod will be engaged by the end of the arm 101. Such engagement will force the rod 111 to the left (Fig. 11)

therebyy causing the pin 112 'to engage the p1n'113 and carry the pawl 109 out of engagement with 'the teeth of pinion 98. lVhen this occurs the tensioned spring 107 operates to rotate pinion 98 backward to its starting or zero position. This zero position is determined bythe engagement of a lug 117 12) on the face of the pinion with the.

under side of t-he rod 111.

It should be noted that when the crank 'arm 92 on: the rock shaft 91 is in engagement with the recess in the level' 93 the rod 111 has been moved to the left (Fig. 11)

and the' pawl 109 is then out of engagement Thus thecrank arm 92, and with it the rock shaft 91, is maintained in such position that the stop arm 95 of the clutch is not in position to be engaged by the lug 90 to throw out the lclutch. As soon, however, as the' rod'111 is moved to the left (F ig. 11) by the engagement therewith of the rei ving arm `101, the lever 93 is moved in a direction to bring its end 93a out of engagement with the crank arm- 92 and the spring `96 on the rock shaft 91v then operates to move the crank arm 92 inwardly into engagement wit the 'recess in the lever 93 carrying with it the stop arm 95l into position to be engaged by the lug 90 to throw out the clutch and stop rotation ofthe shaft 44. lilith such a construction it is readily seen that if the movable arm 101 on the pin 100 be placed in the hole inthe pinion 98 farthest to the right (Fig. 9) thirteen impulses will be given to the pinion 98 by the engagement therewith of the rib 108 before the end of said arm 101 comes into engagement with the end of the rod 111 to move the rod, and with it the lever 93, to a posit-ion where the stop arm 95 of the clutch is placed in a position to be engaged by the lug 96 and thus lthrowout the clutch and stop'rotation of the shaft 44. If, however, the pin 102 on the arm 101 is placed in the hole farthest to the left (Fig. in the pinion 98, only tive impulses will be given to said pinion before the stop'arm 95 is placed in position to be engaged by the lug 96 and thus throw out the clutch and stop rotation of the shaft 44. If the arm .101 is placed in engagement with any one of the remaining holes in the pinion 98 other numbers of impulses will be given to the pinion between the limits 'of five and-thirteen, according to` the angular distance' of the hole from the end of the rod 111. The

series of numbers on the face' of disk 103 correspond to the number of impulses given to the pinion 9S when the crank arm 101 is located in any particular hole 99. Thus, in Fig. 11, the numeral 9 on the disk 103 is shown as being placed opposite the index 105 and, therefore, the arm 101 has been placed in such position that nine impulses .will be given to the pinion 9S before rotation of the shaft 44 is stopped. lAs the pinion 98 is given an'im'pulse, or is turned the distance of one tooth, for each complete rotation of the sleeve 49 on the shaft la and as each complete rotation of the sleeve 49 ywill turn the nail receiving cylinder 2G about its stud 38 a distance equal to the space between two of its nail receiving recesses 12, it 'is seen' that for each impulse of the pinion 98 a nail is delivered to one of the recesses of the nail-receiving cylinder 26. As the number of impulses to be given to the pinion 98 is entirely within the cont-rolof the operative, the number of nails delivered to the nail-receiving cylinder 26 may be predetermined by the operative.. If then, the nailing devices of the machine are to operate upon small sized heels the operative simply turns the disk 103 to a position with the numeral 5 say, beneath the index 105 and the nail-receiving cylinder 26 will, when y the clutch is thrown in, be turned only far e-- gh to pick off from the end of the racen way tive nails. If, on the other hand, the operative is nailing large sized heels which require, say, thirteen nails it is simply necessary for him to place the numeral 13 on the disk 103 beneath the index 105 and the nail-receiving cylinder 20 will be operated to pick off exactly thirteen nails from the The machine is thus provided with means fory predetermining the number of nails to be delivered as a group or gang from the nail-receivingcylinder and, in thisv instance, to the nail carrier of a heeling machine. f

In operating the nail. delivery mechan ism, when, say, five nails Vare to be delivered as a gang from the nail cylinder, a distribu ter block is inserted in its supportingbracket whichhas but five holes'and only the iirst tive of the thirteen distributing tubes 69 arey used, counting to the left (Fig. 7) "from the hole in the bottom plate 36 beneath the recess in the-nail cylinder marked 1.. Each time, then. that the clutch on the shaftllll is thrown into and vout of operation, nails will be delivered to six of the recesses 4-2 which includes the recess remaining-at the delivery v end of the raceway 19.' ,Onmovement of the cover plate 65, however, only the .five nails beyond the raceway are delivered from'the nail cylinder as heretofore explained. -When 'thel counting mechanism is again operated,

the sixth nail of lthe previous delivery from -f series vof five.

the raceway becomes the first of the new series of nails starts from a different one of therecesses'42.

received by the cylinder a new point on the circumference of the cover plate is in position for engagement by the trip 'lever 81- 82. It '1s for this reason that a tooth is ,provided for each recess 42. lith such a construction nails can be delivered to the distributer at the end of each forward movelment of the nail `receiving cylinder and it is 'the base of the chute having been adjusted. so that the nails are maintained at the proper height within the hopper for the best delivery of the same to the raceway, the

clutch of the main machine is thrown in and stopped as hereinbefore described.

thefrollers 4, 4 of the roller raceway within the hopper are constantly rotated and nails are constantly delivered to the table 3 for deliveryfrom the hopper to the exterior raceway 19. If a medium sized heel is being operated upon by the nailing devices the disk 103 is set, for instance, with the numeral 9 opposite the index 105 (as shown in Fig. 11). It will be assumed that there are no nails in the nail-receiving cylinder 2G and that the nail carrier is in its position beneath the nailing devices. Then as the machine begins lo operate the nail carrier '71. is moved about its stud T3 and brought beneath the nail distributer 70. In this movement the cover plate (S5 is moved, but as there are no nails in the cylinder none are delivered from the cylinder to the distributer and lfrom thence to the nail carrier. On the movement of the nail carrier away from the nail distributer, however. the bell crank lever SG-SS moved in such manner as t :tl1row the crank arm 92 and the stop arm 95 on the yrock shaft 01 outwardly,v'liich throws in the clutch and iinniediately starts rotation of shaft- 44. This shaft in turn coimmlnicates'rotarv movement to the nail cylinder 26 and said cylinder is rotated suiiiciently to pick off from the nail raceway nine nails, at the end of which time the clutch is again thrown out and rotation of the shaft- 44 is On the next movement of the nail carrier to bring it beneath the nail distributer the bell crank lever 75-77 is moved in such direction that the lever 81-82 is moved about its pivot to engage one of the teeth on the cover plate It is thus seen that each new l 65 and move the cover plate so that the nine nails in the receiving cylinder are delivered therefrom as a gang. These nails drop through the distributing tubes 69 and through the distributer 70 into the holes arranged for their reception in thenail carrier T1. The nail carrier, immediately upon'` receiving its gang of nails, is moved forward to place these nails under the vdriving devices and as it moves forward the bell crank 813-- 88 is again rocked to move the parts to throw in the clutch and again rotate shaft 44 and the nail cylinder2t5 to pick off nine more nails and hold them in the nail cylinder in readiness for delivery to'the nail carrier on its next movement to a position beneaththe nail distributer. This cycle of operations is of course kept up indefinitely until the main clutch of the machine with which the assorting and delivering mechanism is combined is thrown out and work thus stopped.
