Application filed December 12, 1908, Serial No. 467,180. Renewed November 22, 1909. Serial No. 529,312.

.To all whom it may concern:

Be it known that I, WILLIAM C. STEWART, a subject of the King of Great Britain, residing at Lynn, in the county of Essex and State of Massachusetts, have invented an Improvement in Nail Assorting and Delivering'Mechanisms, of which the following description, in connection with the accompanying drawings, is a specification, like 10.

parts.

The invention to be hereinafter described relates'to boot and shoe machines and more especially to the nail assorting and delivering mechanism of the general type set forth in an application for patent filed by me January 3,; 1908, Serial No. 409,141, to which reference may be had. In the-said prior application, means were shown and described for delivering nailsfrom a hopper to a raceway from which they were delivered singly in predetermined variable numbers to a receiver, and when the receiver had taken its predetermined number of nails from the? raceway, its actuating means was automatically stopped, and the nails delivered to a naildistributer.

With these general features of the machine in view, the aims and objects of the present invention will best be understood and made clear from the following description and accompanying drawing disclosing one charactor of means for putting the invention into practical effect. V

lln the drawings :-Figure 1 is a sideelevation showing the general relations of hopper, raceway, and receiver; Fig. 2 is a section of the hopper on the line 22, Fig. 1; Fig. 3 is an enlarged section of the hopper and nail delivering Wheel on the line 3-3, Fig. 2, showing the raceway and parts within thehopper in elevation; Fig. l is an en larged detached detail view, showing means for causing improperly positioned nails to e thrown from the raceway; Fig. .5 is an enlarged side elevation, parts being broken away, showing the nail receiver actuating means, part of ,the traceway, and adjacent parts; Fig. 6- is a view looking from the right ofFi 5 to show 'more particularly the nail delivering device and its actuating means; Fig. 7, is a section on line 77, Fig. 6; Fig. 8; is a view looking upon the receive nail receiver, and adjacent parts in the d1- 8 rection of the arrow, Fig. 5; Fig 'll is a characters on the drawings representing like section on the line 9 9, Fig. 10., the centrai portion of the raceway being broken out; and Fig, 10 is a section on the line l0-10, Fig. 8, said line being extended to the end of the raceway, and the {scale of said figure so being reduced.

' Referring to Figs. 1 and 2, thenail hopper 1 is sustained by a suitable bracket 2 pro ecting from the machine frame and is provided with a nail elevating or delivering wheel 3 carrying buckets for elevating nails supplied thereto and delivering them upon a shelf or table 4 from which they pass to a roller raceway 5 substantially as pointed out in my prior application, Serial No. 409,140, filed January 3, 1908. The nail elevating wheel 3 is preferably driven by means of a worm wheel 6 from a worm 7 which is itself appropriately driven by a I belt and pulley 8 and 9, connected to asuitable source of power. The members of the roller raceway 5 are driven by suitable gear connectionll, 12, as pointed out in my prior application, with the bevel gear 13 secured to the'shaft 1d and driven by the belt 16 through the pulley 15.

One of the difficulties frequently encounter'ed, in feeding nails in bulk from a hopper, is that the nails become clogged in the nail chute, the passage of which is usually smaller than the receiving part of the hopper, and the weight of the nails dumped into the hopper adds to the .dificulty. I

In the present form of the'invcntion, the chute 17, Fig. 2, terminates at its lower end in a delivery opening, the extent of which isadjustable by means of a sliding gate 18 and a removable barrier 19,, 2. The gate 18 may be substantially as in my prior application, and is provided with an arm 20 jointed to an actuator 21 having a slot 22 into which extends" a setscrew 23, whereby, When the gate 18 is adjusted'as desired it may be clamped in adjusted position.

The barrier 19 is removably supported at y 1 00 the open end of the chute 17 so that bar 5 riers of diflerent sizes may be employed as, circumstances dictate. In the illustrated form of the removable barrier it is provided with hangers 24 adapted to engage pins 25 extending from the wall of the chute, said barrier preferably having means, such as the upwardly extending arm 26, adapted to ,engage a-pin 21 to prevent tipping of the barrier on its hangers 24.

nails.

Extending into the chute 17 and preferably toward the delivery end thereof is a device 28, Fig. 2, for keeping the nails near the delivery endof the chute from bridging or clogging. Various forms of such device may be devised, that illustrated being in the form of a finger extending through the wall ofthe chute 17 and having its end. 29 projecting through the lower open end of the chute and so disposed as to be struck by the blades or buckets of the elevating wheel 3.

This finger may be formed as a spring having one end fixed to the wall of the chute, so that as the elevating wheel revolves, the buckets keep the finger moving and the nails properly agitated. Extending part way across the hopper 1, and, preferably, some distance above the open end of the chute, are the relatively adjustable sustaining or supporting shelves 30, 31, the edge of one extending toward and preferably overlapping the edge of the other to thereby form a passageway 32 for the From this construction it will be apparent that the weight of the great bulk of nails in the upper portion of the hopper and chute is taken off the nails near the opening of the chute, thus relieving to a large extent the liability to bridge or clog and permitting the finger 28 to move the nails freely as the elevating wheel revolves.

Nails delivered to the roller raceway gradually drop with their pointed ends between the rollers, which, as stated in my prior application, are rotated, said nails being then supported by their heads as indicated in Fig. 4. Many of the nails, however, fail to properly position themselves between the rollers of the raceway and must be removed therefrom to the end that they may not interrupt the continuous. travel of properly positioned nails down the raceway.

, As set forth in my prior application, the

members of the roller raceway are provided at some portion of their length with indentations and elevations, as indicated by the corrugations 33, Figs. 3 and 4. Disposed above these corrugations 33 are the clearing members 34, 35, preferably carried by a bracket 36, Fig. 3, which may be held to the wall 37 at the lower portion of the hopper 1, by a set screw 38, or by any other well understood means.

The clearin members 34 and 35 are preferably forme as springs, having their lower end portions turned into substantial parallelism with the axis of the roller raceway and a distance above the same so as to prevent properly positioned nails from being lifted from between the rollers of the raceway, substantially as pointed out in my prior application. I

The lower end portion 39 of the clearing member 34 is upturned slightly and trimmed to a point so that any improperly positioned nail meeting the beveled side of the portion 39. would probably be thrown off the raceway and into the lower portion of the hopper 1.

The lower end portion 40 of the clearing member 35 is separated from the portion 35) of the clearing member 34, so that any improperly positioned nail passing under the clearing member 34 may be forced upward between the two members and discharged from the raceway. The portion 40 of the clearing member 35 is or may be formed withfa shoe 41 extending to ward the poition 35) of the front clearing member, its end being upturned,-as shown, to assist in clearing the raceway of improperly positioned nails. The other end of the shoe 41 extends somewhat beyond the rear end ofthe end portion 40 to provide a clearing shelf or rest onto which improperly positioned nails'may be forced, as will presently appear.

The bracket 36 carriesa device which, for

identification, may be referred to as a nail -St0p and director for causing any improperly positioned nails to be stopped from further movement down the raceway and directed out of the path of nails properly positioned and coming down the raceway. One form of this device is shown in Figs. 3 and 4, wherein 42 is a spring secured to the bracket 36 as by the screw 43, Fig. 3, and projecting inside the hopper above the raceway, said spring carrying a stop 44 inside the hopper and a short distance from the end 45 of said spring. The stop 44 is formed as a plate with a passageway 46 for the heads of properly positioned nails, the construction being such that should an improperly or cross-positioned nail pass the clearing members 34 and 35, it will be stopped from further movement down the raceway by the plate 44, and the pressure against said nail by the heads of properly positioned nails coming down the raceway will force the improperly positioned nail upward by acting on its cylindrical body portion and by the lifting action of the portions 33 of the roller raceway, the spring 42 yielding if necessary to permit the end 45 to direct the said nail thus thrown upward onto the shelf formed by the end of the shoe 41, from which is eventually drops into the bottom portion of the hopper.

Properly positioned nails traveling down the roller raceway 5 are presented to the exterior raceway by which they are supported and finally delivered to the nail receiver and by it transmitted in suitable groups to a nail distributer, as pointed out in my prior application. The exterior raceway comprises the side plates 46, Fig. 1, suitably spaced apart, as indicated in Figs. 8, 9 and 10, to support the nails by their heads, as pointed out'in said application, the delivery end of said exterior raceway being disposed v 1 a bolt 51 which eaaoee I ta adjacent'the nail receiver 47 presently to be described. The exterior raceway has secured thereto two or more side arms 48 having bifurcated upper ends 49, Figs. 8, 9 and 10, adapted to support a cover plate 50, said cover plate being adjustable toward and from the exterior raceway so as to accommodate nails, the heads of which may project more or less above the' surface of the raceway. Any suitable adjusting means may be employed to connect the cover plate 50 with the exterior raceway, said means in the present form of the invention, and, as shown more clearly in Fig. 10, comprising may be clamped in place upon the supports 48 by a nut 52 adjacent the upper portion of the exterior raceway. The'cover plate 56 is provided with an elongated slot 53, through which the bolt 51 passes, and an adjusting screw 54 passes through the top portion of the late 50 and bears on the bolt 51 whereby, a ter said bolt 51 is securedin desired position, the upper end 55 of the coverplate 50 may be adjusted toward or from the top of the exterior raceway in a manner which will be well understood.

The lower end of the cover plate 50, being that end nearer to the receiver 47, has fixed therein a screw bolt 56 similar to the bolt '7 51, said bolt thus carried by the cover plate being seated in the bifurcated ends of the lower supports 48. Passing through the screw bolt 56, which may be held in fixed position with respect ,to support 48 by means of a nut 57, are the adjustmg screws 58, one adjacent either end of said bolt and adapted to bear on the lower surface of the bifurcated ends 49 of the lower support 48 whereby, upon manipulation of the adjusting screws 58 after the nut 57 has been loosened, the bolt 56 and, perforce, the lower end of the cover plate 50 may be adjusted toward and from the top of the raceway.

From the construction thus far described, it will be apparent that not only may the cover plate 50 be adjusted in the manner' stated, but that it may be swung about either of its supporting bolts as a pivot upon loosenin the opposite bolt, so that any nail' lodging in the exterior raceway 46 may be readilyremoved. Pivotally supported upon the bolt 56 is a nail retainer 59, Figs. 8 and 10, a spring 60, secured to the cover plate 50 at 61 and having a finger lift 62 normally holding said nail retainer in its lowered or operative position (as indicated in 10), by engagement with the shoulder 63 on the nail retainer, thus constituting a knife blade joint, the construction being such that upon lifting the end 62 of the spring out of engagement with the shoulder 63, .said nail retainer may be raised from full to dotted line position, as indicated in Fig. 10, and when in full line position, it will be retained stud or bolt 69,

said shaft 74 there by means of said spring. The nail retainer 59 has a nail stop 64 and a side extension 65, Fig. 8, for purposes to be hereinafter more fully described.

As pointed out in 1 y previous application referred to, the nail receiver is preferably in the form of a cylinder, mounted within a hollow cylindrical support. 66, Figs. 8, 9 and 10, which is in turn supported upon a bracket 67 carried by the main supporting frame- The support 66 is provided with a yoke 68 which supports the upper end of a Figs. 8, 9 and 10, upon which the nail receiver 47 is rotatively mounted. The lower end of the stud 69 finds support in the bottom plate .70, and the hollow cylindrical support 66 is provided with an opening in its periphery in which the lower end of the exterior raceway 46 is adapted to rest, said parts being substantially as pointed out in my application to which reference has been made.

The cylindrical nail receiver 47 is provided with a series of nail receiving recesses or chambers 71, said recesses or chambers preferably extending from the periphery of the nail receiver cylinder. Also, as pointed out in the application referred to, the nail receiver 47 is provided with a worm wheel 2 by'which said receiver may be rotated through the medium of a worm 73, Fig. 5, mounted on the shaft 74, which may be drivpn by any suitable means, substantially as pointed out in said prior application. In said prior application, the worm 73 was movable longitudinally on a shaft 74, the

being itself held from longitudinal movement, whereas in the presentelnbodiment of the invention the worm 7 3 is; fixed to the shaft 74 and carries a cam path 75 which is engaged by a roller 76 mounted on a pin 77 carried by the machine frame, Fig. 5, whereby, upon rotation of the shaft 74, as hereinbefore noted, the worm 73 is iven a rotary and longitudinal movement rst in one and then in the opposite direction. The form of the cam 75 and the characteristics of the worm and worm wheel connection between the shaft 74 and nailreceiver 47 are such that, as the wbrm is rotated in one direction, the concurrent longitudinal movement thereof causes the threads of the worm to turn idly between the teeth of the worm wheel and consequently not. rotate the nail receiver; but on longitudinal movement of the worm in the opposite direction the worm wheel and consequently the nail re ceiver will be actuated at high speed, all substantially as pointed out in my prior application, and for the purposes therein noted, the result being that the nail receiver 47 is iven a step by-step movement rotatively to bring the recesses or chambers 71 successively into position to receive a nail delivered from the raceway 46. The cover plate '7 8, the bottom plate 70, and the distributing tubes 79, Fig. 10, may be (if the form and construction set forth in my previous application. Disposed between the nailreceiver 47 and the cylindrical support 66 is the nail feeder. or shutter 80, the purpose of which is to feed nails singly from the exterior raceway 46 into the recesses or chambers 71 of the receiver, in a manner now to be explained.

. It is well understood by those skilled in the art that the successive feeding of nails into a nail receiver is dependent largely upon the continuous control of the nail from the time it is taken from the raceway until it is finally placed in its position in the receiver, such control also involving the capacity of holding the nailin proper position without tilting.

Having reference more particularly to Figs. 6,8, 9 and 10, the nail feeder or shutter 80 consists of a part formed substantially as a cylinder andhaving at one portion a verticalslot 81 formed therein, adapted to receive a nail from the raceway 46. EX- tending cireumferentially into the nail feeder or shutter 80 are a series of slots 82 intersecting the slot 81, Fig. 6, and in the op posite wall of the slot 81, as at 83, are a series of beveled portions. Projecting from the cylindrical supports 66 and extending into the slots 82 of the nail feeder or shutter 80 are a series of fingers 84, the advanced endportions85 of which are beveled, as indicated in Figs. 8 and 9, said beveled end portions 85 being complementary to the beveled portions 83 in the wall of the slot 81 formed in the nail feeder, the construction being such that if the slot 81 in the nail feeder be laced directly opposite the delivery end of the exterior raceway 46, a single nail may be delivered to said slot 81, as 1n dieated in Fig. 9, and if while carrying said nail, the nail feeder be moved about its axis, the nail will be carried by the nail feeder until it meets the beveled end portions 85 of the fingers 84 which will cause the nail to be moved radially inward and occupy a position in one of the slots or chambers 71 of the receiver 47, one of said slots or chambers being properly positioned at the time.

The length of the cylindrical receiver 47 and of the nail feeder or shutter'80 is preferably such as to accommodate nails of the largest size desired to be used, and the slots 81 and 82 and beveled portions 83 may extend substantially the full length of the cylinder, as may also the series of fingers 84, so that, regardless of the length of the nail, it will be under control throughout its entire extent while being transferred from the raceway 46 to the receiver 47.

In order that the nails may be delivered singly from the raceway 46, substantially in the manner hereinbefore stated, it is desir-able that the nail feeder or shutter 80 be given an oscillatory motion about its axis which, as indicated, is coincident with the axis of rotation of the nail receiver 47. Ohviously. any suitable means may be employed to give this characteristic oscillatory motion to the nail feeder or shutter 80, the motion of the feeder and the nail receiver being so timed and related as that nails taken from the raceway by the feeder will be carried to one side thereof and there find a recess or chamber 71 of the receiver ready for their reception, the plain wall of the nail feeder during such movement of a nail from the raceway to a recess or chamber 71 affording a rest or stop for the nail in the feeder, as indicated in Fig. 9.

As one means of securing the characteristic action of the nail feeder, the latter is pro-' vided with a bracket 86 having a recessed portion 87 to receive the rounded end 88 of an adjustable'pitman 89, its other rounded end 90 resting in a suitable socket 91 formed in an arm 92, Fig. 6, loosely mounted upon a stud or shaft 93. Also loosely mounted upon the stud or shaft 93 is an arm 94, Fig. 7, having the roll 95 which bears against a cam'96 secured to the shaft 74. The arm 92 is provided with a projecting lug 97 which bearsupon a similar lug 98, Fig. 7, of the arm 94, and a spring 99 surrounding the hubs of the arms 92 and 94 has one end bearing on the arm 92 at 100 and the other end bearing on the arm 94 as at 101, the

construction being such that the arm 92 has a yielding connection with its actuator or arm 94 whereby any obstruction to the movement of the nail feeder or shutter 80, as by a bent nail, or other cause, will permit the arm 92 to yield and thereby'prevent breakage, as will be well understood.

Disposed between the arm 92 and the nail feeder 80 is a spring 102 acting normally to keep the pitman S9 seated in the arm 92 and bracket 86, and connected to the bracket 86, at 103, is one end of the spring 104, Figs. 5 and 6, the other end being secured at a fixed point, as upon a standard 105, Fig. 5. projecting from the machine frame, said spring 104 normally acting to move the arm to hold the roll 95 against its actuating cam 96.

From the construction thus far described, it will be noted that the nail receiver 47 is given a step-by-step rotative movement through its actuating means to thereby succe'ssively. present the recesses; or chambers 71 to receive nails delivered by the feeder, and that said feeder 80 is given an oscillatory rotfitive movement about the same axis to take a nail from the end of the raceway 46, carry it to one side of said raceway, and there meet a recess or chamber 71 of the receiver, properly positioned to have the nail delivered thereto by the beveled end portion arenas of the fingers 84 which push said nail during the forward oscillatory movement of the feeder into said recess or chamber, said pushing action of the fingers S 1 extending at intervals from near the head portion to near the end portion of the nail, thus preventing any tilting or improper positioning of the nail at any point during its transfer from the exterior raceway to the nail receiver.

In order that there may be'no' uncertainty in nail delivery from the raceway 46 to the nailfeeder, oneof the walls 46 of the raceway is slotted, Figs. 8, 9 and 10, as at 106, and into said slot; projects the beveled end portion 107 of a spring arm 108 which is carried by an arm 109 pivoted at 110 upon a bracket 111 secured to the support 66, said arm 109 having aitoe portion 112 normally held in the pathbfinovement of a lug 113 secured to the nail feeder or shutter 80, as indicated in Fig. 8, whereby as the nail feeder or shutter 80 is oscillated in the manner hereinbefore described, the arm 109 will be moved back and forth on its pivot 110 to cause the end of the spring 107 to feed nails downward toward the end of the raceway l6. As hereinbefore stated, the nail retainer 59, Fig. 10, is provided with a nail stop 64:

, and-a side extending portion 65, the purpose of which parts will now be apparent, because, said nails are pushed from the raceway e16 or are delivered to the nail feeder when the latter is in the position indicated in Fig. 8, with the slot 81 opposite the end of the raceway, the head of the nail may extend above the top of the receiver 47, and the nail stop 64 acting upon the head of the nail thus transferred .to the nail feeder acts as a continuation of the circumferential wall of the receiver and prevents any tiltin or other improper positioning ofthe nail. As the nails are carried by the receiver 17, the side extension or armg65 prevents any upward movement thereof due to vibrations or other causes, said side extension 65 covering the nail receiving chambers 71 in the manner indicated by dotted lines in Fig. 8. y

In my prior application hereinbefore referred to, means were shown and described for predeterminately varying the number of nails to be delivered to the nail receiver and, when said number of nails have thus been delivered, to stop further action of the ma chine so that said nails would be delivered as a group into a nail'distribute'n Such means are also contemplated for use 1n connection with the nail distributing mechanism .of the present invention, an While the form hereinbefore described, but description thereof is unnecessary for the reason that it is fully shown and described in my prior ap lication. t
