' Specification of Letters Patent.

Patented June 16, 1908.

all whom it may concern:

Be it known that I, Cnnsrnn O. SMALL, of

Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have inventeda new and useful Improvement 1n Heei-Nadmg Machines, of

is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature. This invention relates to heel attaching machines.

" The invention is shown embodied in a ma chine of the general type of that shown in Letters Patent, No. 467,242, granted to me from the following description that featurcs of the invention may be used to advantage in heel attaching machines of other types. Certain features of the invention are particularly of advantage when used in a with a stationary nail templet and a shoe support arranged to be moved toward said nail templet to press a heel upon the shoe and hold it securely in position while the attaching'nails are being driven. In the machine shown in said prior patent, vertical movement is imparted to the shoe supportby a toggle which 15 actuated from a cam by an intermediate lever connec-' tion. The meehanism'for imparting move ment to the shoe support s required to exert considerable pressure upon the support in order to hold the heel firmly in position while it is being attached. On account of the reat stress to which it is subjectedfsaid mechanism has been found too complicated to be of practical use in a heel attaching machine.

An important object of the present inventionis to simplify and improve mechanism of this nature to the end that it may be durable and not liable to fracture on account of the great pressure which it is required that it shall impart to the heel. In carrying out this part of the invention, the nail templet is restrained from vertical movement as in the machine of said prior patentand a'shoe support is arranged for vertical movement beneath the nail templet and is also arranged for lateral movement for convenience in applying and removing a shoe. Beneath the shoe support in its Working position and in line substantially with thedriver passages of the nailtemplet is provided a cam, by the It will be obvious, however,

,-.Ymovement-ofwhich about a horizontal axis is effected thevertical movement of the shoe support to press a heel firmly upon the shoe, said heel and shoe being clamped between the shoe support and'the face of fhe nail templet. Between the shoe support and the cam is arranged a pressure head which is sustained by the cam and transmits movement directly from the cam to the shoe su port. I

' y arranging the cam below the shoe support in line with the nail templet the necessity is avoided of providing other mechanical elements between the cam and the shoe support for transmitting and modifying the movement of the cam, while at the same time the function of the cam is retained. It will be understood that theuse of acam interposed between the shoe support and the primary source of power in the machineis advantag'eous in ,that it constitutes a simple and durable mechanical element for modifying, in the manner required,'the motion derived from the primary source of power. For example, it readily permits the shoe suportto be so actuated that it is maintained m stationary position while the nails are beingforced into and'through the heel and heel seat by thedrivers. 1 The arrangement herein shown is such that the pressure head has engagement with the edge of the .cam, and the cam is sov shaped that a portion of said 'edgeis formed to cause vertical movement ofthe pressure head t'osubject the heel topressure and a following portion of said edge is concentric to the axis of the cam to main.-

tain the shoe support in stationary position while the heelis being attached. In the par ticular embodiment of the invention hereinafter described the cam isarranged for rotation and the attachment of a heel and a top lift is effected in a single revolution. To this I end the cam is so shaped that during a single revolution it causes two vertical reeiproca tions of the pressure headand shoe support. While, as will be obvious, the features above referred to are independent of mechanism fo r bringing heels and top lifts into position to be attached, have shown herein novel mechanism forfseouring this result.

-The features of novelty in the mechanism and arrangement of parts, will be hereinafter described and defined in the claims.

The frame A of the machine comprises the side portions (1 a, which are preferably connected together by an iitegral base section a and intermediate sec ion a and a top section (1 see Fig. 3. The upper end a of the. side portions a, a are made flat to receive the removable cross-head guides a, (L7. Each ofthese guides has a foot a, (L through which bolts a" pass to securethem to the main f ame. The guides have vertical re cesses a see Fig. 5, for receiving the end The crosshead has two side portions 1), I) and a top portion 12 see Fig. 3, which is integral with the sidesand curved downwardly at each end to form the end portions 1) which extend through the recesses (1 The portions If are provided with grooves l) in either side, Fig. 11 to lit the surfaces (f', I)", b in the guides a, a and insure the accurate movement of the cross-head: The sides I), l) of the cross-head are carried down at the center I) to form bearings for the shaft 7) upon which the rotary head is mounted. This arched form of cross-head provides great strei'igth with a comparativelysmall quantity of metal, so that-a ligl'it yet strong crosshead is secured. The front side 7/ is open below the shaft I) of the rotary head tepermit the removal of the awl and driver blocks and other im )lements carried by the arms of the head. T he end portions 5" of the crosshead. are extended outside of the guides a, (1. where they form trunnions i) to receive the upper ends of connecting rods 1)" the lower ends of which are secured to the crank pins 0 upon the gears (l. The gears are mounted at the outer ends of the shaft 0 which has bearing in the boxes secured to the under surface of the base section a, see

Fig. 3i The gears are connected with the drivingshaft by means of small pnnons c,

seeFig. 22, on. thepulle'y shaft flh-e. shaft 0 has also formed upon or attached to it the pinions (l which engage gears (1' on a short shaft (1 located over the shaft 0 and having bearing in pillow blocks (1 carried upon the base section o see Fig. 1. The short shaft (1 supports a pressure cam l) forlifting the "aclr 0 force the heel against the te-mplet, as hereinafter described. A guide block it) attached to the side portions it, a of the frame, being located directly above the, pressure cam. The block has the guiding recess (a, which is covered by thiti cap plate a and receives the pressure mechanism which includes a slide The slide is recessed in its lower face to receive the stem of a roll support 1*, which sustains the roll (2* arranged to rest upon the )ressure. cam D above referred to. It will be understood that the roll 0" is of advantage in preventing the wear of the cam l) which would be caused it'- the ram 1) had rubbingcontact withthepressure head. The upper end of the slide 0 is reduced and screw-t1n'eaded at c to receive an adjustable pressure head this head having handles by which it may be turned upon the screw-tbreaded portion to adjust it with relation to the pressure cam l). Preferably a spring, herein shown as a block of rubber e",

is interposed between the upper end of the stem of the roll support i amhthe shde e for.

imparting aslight yielding quality to the action of the pressure head. 0. The slide a" has arms e which are connected by springs N" with the base section (1 to assist in holding the slide normally down with theroll 1" in contact with the pressure cam l).

The pressure cam as herein shown is formed with a lifting portion (1 to elevate the pressure head and jack for compressing the heel blank on the shoe, a holdingportion(l for sustaining the jack while the heel blank is pricked and the attaching nails driven, a releasing portion to permit the downward movement of the jack and allow the top lift to be put into place, a second lifting nation 11" for-spanking on the top lift, and a final releasing portion (Z to permit the downward movement of the ack to allow the shoe to be reinoved. It will be obvious that other means than the'cam may be arranged in substantial alinement with the pressure head for actuating the pressure head and that the invention is not limited to the particular pressure ,apply'ing device herein shown.

The pressure head 6 has a recesse extending around it near its upper end to receive and hold the fork f which extends downwardly and backwardly from the fron;

, lower corner of the jack spindlcj" to connect the jack to the pressure head.

The referred form of ack illustrated I l most clearl in Iws. 12' 13 and 14 comp r o a e prises a slide] having a vertical sleeve and arranged to move horizontally in guides f formed on or secured to the intermediate 'sure head 1 rods f see Figs. 12, 13, and 14, Whichare geared together at f. One of the shafts is provided with a handle 1"" by which the shafts may be turned, and the handle has a pawl f to engage the ratchet teeth of the iixed ratchetf for locking the shafts in the position to which they may be turned. The

shafts preferably do not, extend to the top of the jlackybut are provided below the upper surface of the jack with horizontally bent arms f to which are attached the shoe,

preferably made of spring metal, so that they may yield slightly when the shafts f are turned to bring the blocks into contact with the shoe for centering it.

The jack is manually moved from position for receiving a shoe, shown in Fig. 3, to position in operative engagement with the pres- The movement of the jaclr from operative position over the pressure head to position for receiving a shoe, showili in Figs. 3 and 12, is effected-automatically after theheel and top lift have been attached, by the cam f mounted on the V611- tical shaft G, see Fig. 12 The cam h s an extension or lug f adapted to engage L pin f on a leverf Whichis pivoted to t e intermediate frame section a and conn-cted with the jack by a'linkf. The verticalshaft G is actuated from the pulley shaft 0 by means of a worm wheel on the vertical shaft and a Worm 5 on the pulley shaft. The vertical shaft carries at its upper end a cam g" having a groove g" which receives a stud g on a plate 9 The plate slides in ways 9 in the table H of the machine, which has rearwardly extended guiding arms h for this purpose, and is con nected at its forward end to the nail carrier g". The connectimi between the plate and the nail carrier comprises a. groove 9 in the front end of the plate which receives a rib g of the nail carrier, the parts being secured together by a removable pin g", which permits the easy removal of one nail carrier and the placingof another in position. The cam g operates for sliding the nail'carrier from the osition shown in Fi 3 in which it rethe two side portions, thus strengthening the table. The portion h of the table has a lip whicheXtends under a portion of the cross piece a. The table has also on its sides ribs it which are received in guiding grooves 72, in the inner faces of the frame sections a, a, as shown in Fig. 17. The sides of the table are overlapped by the feet a of the cross-head guides (1 (L7 to resist upward thrust against the table in the operation of the machine. The table is secured in position by bolts k which extend through the frame into the depending portions h of the table, as shown in Figs. 5 and 6.

lleel blanks and top lift blanks are contained rcs ectively in stacks K and N.-

These stac is are preferably similar in construction and therefore only one of them, namely, the heel blank stack is illustrated in detail and a description of this stack will sutlice. for an understanding of the construction of both stacks. The stack is preferably made in three relatively adjustable parts 717,

7c, and arranged as shown in cross section in figs. 21 and .22. The parts It, L" are angular in shape so as to engage the breast and the sides of the heels, and these parts are supported by a bracket /c'*,.see Fig. 22, which is mounted on a plate It hereinafter described. The bracket If has a horizontal groove k which receives a rib It on the outer face of the parts 7c and ll." of the stack, and said parts have right and left scrcw-tlireadeil lugs It", In which receive the oppositely scrmv-thrcaded portions of an adjusting screw It by means of which the said parts /r, it" may be moved toward-and from each other to adapt the stack to hold heels varying in width. The part 7i. of the heel blank stack is shapedin cross section to embrace the rounded rear end of the. heel blanks, as shown in Figs. 21 and 22. This part k is attached to a bracket It, the foot of whichis slotted to enable the bracket to be adjustably secured to the table ll. tion, according to the length of the heel from its breast to its rear end, by a clamping screw 7r", as shown in Fig. 5. As heretofore. stated, the top lift blank stack N, which comprises the. parts n, n, and n is the same in construction as the heel blank stack. If desired the stacks may be constructed with a single plate to engage the breast of the heel blank or top lift instead of the two angular plates Ir, k, or ,t, n.

The plate It is supported by it vertically adjustable block K which in turn is sustained by a rigid. bracket Y attached to the frame of the machine. The plate It" has .a depending 'p rtion K which is movably connected t6 t 10 block K by bolts K which pass loosely through slots K in the block and into the depending portion of the late [612 as showii' most clearly in Fig. 4". he plate 71: 1s normally pressed upward as far as the slots The bracket is secured in adjusted posi} K permit by a spring K. The depending portion K ofthe plate k has guiding ribs K which cooperate with grooves K in the bracket K to guide the plate in its move -ments relative to the block K. The block K is adjusted with relation to the bracket K" by means of the screw bolt 7c the stem of which is held against longitudinal movement in the arm K of the bracket and the threaded portion of which is received in a screwthreaded aperture in the block K. By adjusting the block K the plate 7c and the heel blank carrier is, which is supported thereon, are moved toward or from the fixed portion k of the heel stack to vary the size of the opening between said carrier and the stack according to the thickness of heels which are being fed.

The plate It has aguidin groove is in which the heel blank carrier 7c is movable. The carrier is provided on its upper face at a distance from its forward end with an abutment 7%, see Fig. 5, to engage the breast of the lowermost heel blank in the stack and push it out of the stack and toward the rear of the machine. The heel blank carrier is actuated from a cam 76 The cam has a groove k for operating two lovers 7c", 7r which are provided with rolls is standing in the groove at a considerable distance apart so that said levers receive substantially opposite movements from the cam. The lever 7r has at its forward end two arms W and K125. The arm if is connected by a link it with a stud 7: depending from the lower face of the carrier It and extending through a slot in the plate it. By means of this connection between the carrier and the cam 7c the carrier is operated to push a heel blank rearwardly from within the stack to a position over a lifting device M b which it is delivered to the heel blank hofiler It.

The heel blank holder is is carried by the feed slide 10 which is movable transversely of the direction of movement of the heel blank carrier in guideways on the under face of the table if.

shown in Fig. 5, and the lifting device M is employed for lifting the heel blanks off from the carrier 71: and placing them in the heel blank holder. supported in the inner end portion of the plate It and comprises a depressed portion m and laterally extending wings m. The depressed portion receives the end portion. ofthe carrier ls in'its feeding stroke and the wings m receive the heel blank sup )orted by the carrier, the front ends of the wings being inclined downward. slightly, as shown in Fig. 5, to facilitate the placing of the heel blank upon them. The lifting device is provided with depending arms extending through bosses in on tlielower side of the plate 17 as shown in Fig. 5, and the arms are con-- The lifting device is movably The feed slide and blank bolder are located above the carrier lt' asv nected by a cross-rod which supports a roll m, as shown in Fig. 5. The stud k depending from the carrier is provided with a wedge the heel blank carrier 7c.

The feed slide k is movable transversely of the direction of movement of the carrier It" 4 for transferring heel blanks from a position at the side of the machine, where they are delivered by the carrier, to a central position between the jack and the cross-head carrying the awls and drivers for attaching the heel blank to a shoe. To this end the slide k is actuated by an arm is of the lever Ir" above referred to, being connected to said arm by an adjustable link 7c secured to a boss It depending therefrom, as shown in dotted lines in Figs. 4 and i and in full lines in Fig. 7. The link 76 is preferably made in two parts which can be relatively adjusted by a nut It for lengthening and shortening the link and thereby varying the position of the feed slide. During the feeding movement of the carrier 7r the feed slide is movedlto the right in Fig. 4 to put the heel blank holder in position to receive the heel blank from the carrier, as shown in Fig. 4, and during the return movement of the carrier the feed slide is moved to the left to carry the heel blank into attaching position, as shown in Fig. 4.

Theheel l'ilank holder is, with which the feed slide'is provided, comprises a breast. The breast.

gage 7c and a back gage 'k. gage is preferably arranged for adjustment transversely of the feed slide la -for determining the position of the breast of the heel, but issecured rigidly in adjusted position. The back gage k is recessed at 76" and is mounted to move transversely of the feed slide for opening and closing the holder. To this end the back gage has a shank 7c *-adapt ed to slide in ways on the under side of the feed slide, as shown in dotted lines in Figs. 4 and 4 and in full lines inFig. 7-. The back gage'is acted upon by a lever 7c for holding it normally pressed toward the breast gage 7r to clam a heel blank. The leverk is pivoted at A and has a long arm is for en.- gaging the back gage and a short arm is which is acted upon by a sprin k secured to the slides For the purpose 0' opening the holder to permit the heel blank to be lifted into it by the lifting device M the heel blank carrier is has a laterally projecting arm m see Fig. 4, arranged to engage a cooperating It will be understood that as tion of the plate n.

lug is de ending from the shank of the back gage. T e arm m moves the back gage against the influence of the spring k *as the carrier approaches the end of its feeding movement. It is to be understood that the feed slide it occupies its outermost position at the right-hand end of its movement, see Fig. east the time the carrier 1c comes to the end of its feeding movement bringing the heel blank which is to be lifted into the holder. The heel blank carrier 7c during its feeding movement 'therefore serves not only to convey a heel blank from the stack K, the position of which is indicated in m is withdrawn from under the roll m. to

permit the lifting device to descend into position to receive another heel blank.

The attaching mechanism of the machine, hereinafter further described, is constructed and operated for first attaching a heel blank, leaving the nails projecting slightly from the surface of theheel, and then spanking a top lift upon the heel over the projectingends-of thenails. lift feeding mechanims are thereafter actuated for n'esenting heel blanks and top lifts alternately in attaching position.

The mechanism for transferring the top lifts from the stackiN toattaching position is similar in construction and operation to the mechanism for transferring the heel blanks from thestack K to attaching position. To

this end a plate n is providecLwhich supports the members a, n of the top lift stack and said plate is grooved to form a guidewayfor a top lift carrier 11". The plate a is supported by a vertically adjustableblock N,

. which in turn is sustained by a rigid bracket The heel blank feeding andtop I N attached to the frame of the machine.

The plate a has a depending portion N whichis movably connected to the block N by bolts [N which pass loosel y through slots N in the block and into the depending poriressed upward as far as the slots N permit y a spring N. i The depending portion N of the plate has the guiding ribs N which The plate is normally cooperate with grooves N in the bracket N to guide the plate in its movement relatively to the block. The block is adjusted with relation to the bracket by means of the screw bolt N, the stem of which is held against longitudinal movement in the arm N of the bracket and the threaded ortion of which is received in ascrew-thrca ed a erture in the block N. By adjusting the b oek the table a and the top lift carrier a which is supported thereon, are moved toward or from the fixed portion n of the top lift stack to vary the size of the opening between said carrier and the stack, see Fig. 6, according to the thickness of top lifts which are being fed.

The top lift carrier "a? is provided on its upper face at a distance from its forward end with an abutment a to engage the breast of the lowermost top lift in the stack and ush it out of the stack toward the rear 0' the machine; cam 7c, heretofore described, being connected with said cam by the lever 7c, one arm of which has the stud 7c located in the groove of said cam, and another arm 7c of which is connected by a link a with a stud a depending from the lower face of the car rier and extending through a slot in the plate The carrier is actuated from the,

a. By means of this connection between.

the top lift carrier and the cam the carrier is operated to push a top lift rearwardly from within the stack, the position of which is indicated in broken lines in Fig. 4, to a position over the top lift elevating device a", by which it is delivered to the top lift holder.

The top lift holder is carried by the top lift feed slide 0, which is movable transversely of tlfe direction of movement of the top lift carrier in guideways inthe under side of the table II.- The feed slide and holder are 10- v cated above the carrier, as shown in Figs. 6

. ported by the carrier.

and 7, and the lifting device a is employed for elevating the top lifts from the carrier and placing them in the holder. The lifting device is movably sustained in an arm or bracket a formed on or secured to the plate W, as shown in Figs. 6, 7, and 19, and having depending stems "n 'and being normally pressed upward by sprin s n surrounding the stems a between the bracket n" and the device, as shown most clearly in Fig. 7. The lifting device comprises a depressed portion a and laterally extending wings a. The depressed part receives and constitutes a gulde for the end portion a of the carrier 11)", and the wings a receive the top lift sup- The end portion a of the carrier is rovided with a block n" havin an incline lower face ada )ted to engage the lifting device n" and hol it in a depressed position until the carrier, in its forward movement, has reached a point where the'top lift being conveyed by it is over the lifting device, and thereafter in its continued advance movement, toward the right in Fig. 6, to pass off the lifting'device whereby to release said lifting device and permit the springs, n to elevate it for putting the top.

lift into the holder of the top 1ft feed slide 0 The top liftholder com rises a breast gage 0 and a baclt gage 0. he breast age is rigidly secured to the'feed slide, whllethe back gage is movable thereon, being provided with a shank 0" which is guided in ways 0 on the lower side of the slide 0 for movement toward and from the breast gage for clam ing and releasing atop lift. The back gage 1as a V-shaped face 0 for engaging the rounded rear end of the top lift and positioning it accurately. upon by a lever 0 for holding it normally pressed toward the breast gage to clamp a top lift. The lever 0 is pivoted at 0 to the feed slide and has a long arm for engaging the back gage and a short arm to which is connected one end of a spring 0, the other The back a e is acted I end of which is secured to the slide. For the outermost position at the left-hand end of its movement, see Fig. 4, at the time the carrier a comes to the end of its feeding movement for bringing the to lift into position to be delivered to the hold iar. The to lift carrier rr" therefore serves during its fee ing movement not only to feed a top lift from the stack N toward the rear of the machine and deposit it u on the lifter a, but to open. the top lift holr er and to release the lifting device to permit it to force the top liftoff from the carrier and into the holder. When the carrier returns toward the front of the machine the spring 0 actu'ates the lever 0 to cause the back gage to clamp the top lift against the breast gage and the block a on the end of the carrier forces the lifting device n down into position to receive the next top lift.

The to lift feed slide 0 is actuated from the cam lc by the lever 7c", the arm 76 of which is connected to the feed slide by link o attaehed to the depending stud 0". The link 0 is preferably'made in two pa ts which may be relatively adjusted by the nut 0 to lengthen or shorten the link [lor accurately positioning the to) lift holder with relation to the templet am jack when the feed slide is in the position shown in Fig. 4 for the top lift to be attached. I It will be understood from the above deof t and top lift feeding devices are moved simultaneously but in opposite directions, the heel blank carrier advancing to deliver aheel to its cooperating feed slide while the top lift carrier is makin its return movement to the stack N, and the heel blank feed slide k'- movin to afcentral position to deliver the heel b ank received from its carrier while 12o scription of the construction and operationv 1e feeding mechanism that the heel blank 'moved into position to receive another heel blank from the carrier 7r, as shown in Fig. 4", and tlureafter, in the upward movement of the jack and-shoe, the top lift is attached to the heel. I

The rotary head has four arms, one of which may carry a gang of awls, the second a gang of drivers, the third, nothing, and the fourth, if desired, a breasting device. The

-mechanism for rotating the head is substantially like that in prior machines with the exception that the cam plate P is supported at its upper end 7) by a cross-brace and sup port 7) fastened to the 'upper ends of the guides a, a, see Fig. 1, the ends 79 of said cross-piece or brace acting as stra )s to lock the upper ends of the guides toget ier.

lit will be observed that the top lift and heel blank stacks are located nearer the )lace of attachment of the top lifts and heel blanks than they are inthe patent above referred to, so that the feeding of the heel blanks and top lifts is more direct. In order that this may be acconwlislual, the rotary head shaft 1) is lengthened by being carried forward; its forward bearing (1 is also lengthened, and the cam plate l. set out quite a little distance from the front of the crosshead. This permits the heel blank stack K and the top lift stack "N to be located so close to the place of attachment that the heel blank and toplift may be moved directly to the holders and the holders by a single movement advance them into attaching position.

The starting and stopping mechanism comprises a driven pulley and fly wheel S having a cavity s, see Fig. 8, forming one. section of a clutch and another clutch section s adapted to enter the recess .9 and having a grooved sleeve s". This section is arranged to slide upon the pulley shaft, and it is moved into engagcn'lent with the section 8 of the clutch by the lever s pivoted at s", and hav ing a forked end )rovided' with pins which enter the groove of the sleeve s, the slide bar a having a block or braclwt s" carrying a roll 8 which bears against the vertically movable cam s upon the vertical shaft G. A spring s". see Fig. 2, acts against the slide bar 8'' to move the section of vthe clutch s from the other section and also to force the cam roll 8 into a groove. or notch s" in the cam s, see Fig. The cam roll at is moved out of the groove or notch s to start the machine by means of the trcadle s", pivoted at s", and engaging by its end 8? a wedgesurface on the block s, see Fig. 8, shaped so that upon the upward movement of the treadle end, the roll is moved out of engagement with the cam and the driven member of the clutch thrown into contact with the driving member. The machine beginning to operate causes the surface of the cam beyond the notch to come in contact with the roll and thus hold the driven member of the clutch in the position in which it has been moved by the treadle. It is-often desirable to stop the machine before it has completed'its movements. To accomplish this, there is used an auxiliary treadle s pivoted at s and connected with the slide cam s by a forked end 8 having pmss wluchenter a groove in the hub of the cam The cam is moved d0wnward upon the shaft G by a ring By the downward movement oft 1e treadle the cam is moved upward on the shaft in opposition to this siring and the cam surface which extends from the groove disengaged from the roll 8 permittingthe spring 8 to operate to disengage the driven member of the clutch from the driving member and thus stop the machine. To again start it, the starting treadle s is operated to throw back or move away the roll 8 from the cam hub, as in the original starting of the machine, and

this permits the spring 8 to push the cam s downwardsufliciently to cause it to again act to bear against the roll 8 The driven member of the clutch u on disengagement from the driving member ras its back surface brought into contact with a friction ring 8 carried by the holder 8 There is placed on the pulley shafta ratchet Wheel 0, Fig. 20, and on the'frame a pawl to engage the ratchet. This is for the purpose of preventing the machine from being turned in the wrong direction, or the parts from being moved back ward.
