' HEEL-BURNISHING MACHINE.

Application filed May 2, 1906, Serial No. 314,807.

To all whom it may concern:

Be'it known that'I, CHARLES E. Hoon, a

citizen of the United States, residing at with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In the manufacture of boots and shoes the shape or contour ofthe heel plays an important part in the production of the desired effect presented by the boot or shoe as a whole. For the best eifects also the heel is rarely of uniform shape or curvature varies constantly from the breast line at one side, around the back of the heel to the breast line at the opposite side. This variation in shape is produced in art by the heel shaver and in part by the scouring which follows the shaving. All care and effort may, however, prov'eto have been wasted or lar ely nullified if the desired shape produce first b shaving and then by scouring is not repro need or enhanced by the final finishing of the heel surface.

. A number of methods or processes are in existence for applying to the exposed heel surface a wax or finish which may be brushed up upon a brush or felt wheel to produce a finished surface without changing the general shape left by the scourer, but finishes of this sort are not of the most permanent character, the most permanent finishes being obtained only by means of a -heated ironing or burnishing iron or tool.

My invention relates particularly to machines of the latter type, and it aims to provide a burnishing machine which can be relied upon to give a perfectly accurate burnished heel surface of predetermined desired shape or curvature to heighten the effect produced by the scouring or even to change it if desired.

Prlor to m form curvature throi hout and adapted either to rotate or oscillate against the heel invention, so far as I am acquainted with the art, heel burnishingg. v machines have been either of fixed and 11111- Speoification of Letters Patent. 1 Patented flIay 1910,

struction would permit, the shape given to the heel by the scouring. It has been found impossible, however, to produce a tool of this latter character that will follow accu-' rately and sufficiently an irregularly shaped heel. Furthermore itis desirable not only to follow accurately a heel shape, b'ut if necessary to be able to heightenitl'ie -efiects or shapes during and by the burnishing process over and abovethose produced by the scouring'and this, of course, a merely following or adapting tool obviously cannot do.

My invention contemplates among other things a burnishing'tool whichis givena predetermined and irregular shape or pat tern such that when presented properly to a heel will produce 'a burnished heel surface of redetermined variable character, either to ollow accurately or if necessary to mod ify the surface left by the scouring.

In the preferred embodiment of my'invention I provide a tool haVing-a'surface from one to the other limit 0 its active face which shall be complemental to the desired heel surface from-one to the other end thereof, and this tool'is 'given'a short and rapid vibratory or oscillatory action to produce the required ironing or burnishing 'ef-V fect upon the heel surface, and is caused gradually to progress around the heel, or the heel is caused to rogress along the iron so that new parts of the tool are brought into position as required to act upon suc cessively new parts of the heel, in predetermined order or adjustment so that the surface of the iron', that is actin for thetime being upon a given surface of the heelshall always conform accurately to that heel surface or to the desired'heel surface'thereat,

even though much irregularity is required ,in the surface at various: points around -the This tool may be made sectional if desired,

A s oeupon its last is placed in hlock cause similar rotation of the yoke 15 the machine in the-position indicated in dotcarrying the tool spindle and tool to carry 1 ted line'sfFig 1, with the top lift of the, the latter about the heel.

The lower end of in position. Referring still to'Fig. 7 and said rack is connected at 22 with a rocker assuming the shoe to be. ositioned as indilever 23 fulcrumed at 24 in the column and cated in dotted lines wi the heelresting 'connectegl at' 25 with a pitman 26 leading to upon the breast gpge 11, if the tool 12 be a crank p'in 27on-a worm gear428 journaled rolled about the eel from -'the position at at 29" in the column. This worm gear is driven by a worm 3O fastened on a clutch shaft 31 journaled in the column. Loose upon this clutch shaft is a clutch member 32, the sleeve like hub of which is extended rearwardly or to-the left, Fig. 1, and is fit ted outside said' column with fast and loose is a clutch holding or timing device shown as a bell crank 38' the lon er dependingarm of which extends normally-in front of a lug or'seat 39 on said lever, against which said lever is pulled by a spring 40. The horizontal a'rmrofsaid bell crank extends nor-' mally in front of the pitman extension 41.

WVhen the treadle lever is depressed to re-' lease the clutch and rotate the shaft this bell crank 38 springs into the seat 39 causing the end of its horizontal arm to be raised into the path of movement ofsaid pitman extension 41, so that when the said exten-,. 'sion turning in the directiongof the arrow,

Fig. -1, completes one revolution it strikes the end of-saidbell crank arm, depresses the 'latterand -thereby disengages the depending arm from-the seat 39. This releases the treadle and permits the latter to be raised to cut out the clutch. Thus one depression of the treadle causes one and only one rotation of the worm wheel 28, produced by a predetermined number of rotations of the worm. lVhen cut out, the worm shaft is arrested by contact ofthe lug 42 thereof with a spring arm or stop -t3,which cushions the same againstshocks. In lieu of the clutch described any other well known or suitable type may be employed.

Rotation of the worm'gear by turning the crank pin 27 through one revolution causes the rack 21 to be first depressed and then raised, thereby through the rack gear 20 to rotate the gear shaft.17, to carry the tool spindle and its-tool. first around the heel in one dire'ction'to the opposite side thereof from itsstarting point, and-back again to its: starting point, giving two complete traverses fof the tool over the heeltsurface. I prefer-aplurality. of traverses of the too] over theheel surface, but of course a machine may be adapted in a manner readily understood by any skilled mechanic to vary the number of traverses according to the results desired.

For the best'results the contact of thetool with the'heel should not be relied upon to cause that rolling action or travelingaction of the tool, which is necessa to, cause-its activesurface to progress-as t e tool travels about the h eel.- To 1'mpart'a positive progressive movement to the as 1.

This spiral gear, see Fig. 11, has amating gear 46, fast on a shaft 47 which extends parallel with the yoke 15, see Fig. 8,'and is ournaled in bearings 48 extending therefrom.

Bymeans-of this train of spiralgearing itis'clear that go as the burnishing tool 12 is; revolved about the gear shaft-.l'Z-and the heel, it will be given rotative movement about, its own axis 13 which will cause that art of the tool surface which is presente ,to the ,heel to 35 progress gradually along the heelsurface as well as circle about the heel; and it matters, not whether the movement of the tool about the heel be inone or;v.the-opposite direction, the same tool.' surface"will always be -presented to thesameheel-surfaceso that a plurality of traverses; of ,the'heel may-always be had with entir'ezs'afet i and assurance that the resultant heel sur ace will be as prede terminately arranged by the shaping of the tool. a

To produce the oscillations of the tool thereby to obtain the burnishing action at the point of contact of the tool with the work, it. is only-necessary to reci rocate'the 100.

splined spiral fgear 50' on its s aft 47-to cause its teeth sliding in the teeth of the mating spiralfil, to produce an oscillation of the, latter and the attached tool, and of course, this oscillation will result whatever be the rotative position of the tool relative to its own axis 13. To accomplish this reciproc'ation of the spiral 50 and its sleeve 49 I have provided the latter, at its end opposite said gear with a'flange 52 which is embraced between; the head 53- and an opposed plate 54 secured thereto. This head has pivotally connected to it at 53*,an eccentric rod 54:", leading to'an eccentric 55 upon a sleeve 55", which surrounds the gear shaft 11;; 17, see Fig. 6. This 'sleeve extends rearwardly in the hearings provided therefor in the column, and at its rear end but at the right of the gear 20. Fig. 1, is provided with a belt pulle 56'which may be belted to any suitable pu ley, not shown, but which will rotate said sleeve at the proper speed to cause rapid" reciprocations of the splined spiral gear 50 and produce thereby-rapid' To assist in guiding the spiral gear 50 in its reciprocations I have provided the head -53, see Figs. 6 and 10, with a guidingarm 57 which slides freely; upon alst-ud fast e too spin e 1.3.

' 62 that rises past the gear shaft, see

and near its upper end 'is adjustablg con straig oints of their sides forward to'the breast i lowermost-position, whlchis at about the revolved by the rack and rack gear-bodily about the 'heel'it is clear that at any point in its travel of thetool either bodily about the heel, or rotatively about its own axis, the reciprocations of the'spiralgear 50wi1l oscillate the-tool throughout and consequently at any point of contact with the work. ThlS- arrangement furnishes an exceedingly sim-- ple and efi'ective mechanism for accomplish mg this result. As a matter of fact the oscillations, the progressive rotation and the revolution of the tool about the heel proceed simultaneously. If the heel were semicircular orra'pproximatelysemicircular in shape their the swing-' ing of the tool spindle about the axis of the gear shaft would cause the tool to "travel ap-} proximately in the'line of curvature of the heel surfaces In practice, however, heels are rarely of approximately semicircular shape, they present, as a rule, substantially flat or t surfaces from about the middle me. Because of this and because the toolcommences its work at the breast line at one side of the'heel and continues to the breast line at the opposite side of the heel the,

swinging movement should not commence until the tool has progressed for some dis-- tance first up the side of the heel and then after it has swung about the back thereof, the swinging movement should cease short of the limit of its traverse toward the breast of the opposite side.

The necessary substantially straight traverse of the tool and heel one relative to the other from the breast line rearward atone side and finally from the middle of the heel breast-ward at the op osite side ma be had by moving either or Both the mem ers, but I have found it more. convenient to restrict the moyements of the tool to those of rotation and revolution alone and to obtain the substantially straight relative movements by moving the heel past the tool. For this purpose the jack plate 3 and jack by which the-.

shoe is jacked into position are made to rise and fall vertically as heretofore stated. To control this movement so that it may'occur at the proper times and speeds I have ro'- vided said jack, see F1gs.'1,'7, 8, an 9, with a pivoted block 59 embraced by the forked end of an arm 60 which is fulcrumed at 61 upon the column head. Jointed to this arm between its ends, is a connectin r nected by means of a clamp stud 63 y slot engagement with a lever 64 fulcrumed -at 65 ,upon the column head and bear wor at its free end upon a camorpattern 66 ast on the ear shaft 17. -This. gear shaft as stated is in fixedbearings and revolvesthe tool aboutthe. back. of the heel. "Consequently'this cam may-beand is so shaped, as shown, that when the machine is first started and before the crank pin 27, Fig. 1,

has moved far enou h to. impart to the tool its maximum rate' 0 traverses in a circular direction the jack will be dropped at a relatively. high speed past the too to cause the substant1allystraight sideof the heel from the breast rearward to about'the middle of the heel topass in frontof and be acted upon by the oscillations thereof.

In as much as the progressive rotationof the-tool about its own axis in the cons'truction shown results from the revolution to carry the tool about the heel, it is clear that there will be little progressioniof the tool .to change the tool surface presented to the heel duringthe drop of the heel past the .tool. This is no detriment rather, it is as desired, because from the breast rearward to about'the middle of the heel there is as a rule little or no change in vertical or trans-' -verse'curvature of the heel face. i

At about the time the heel reaches its time when the heel curvature commences to exhibit variations, the movement of the crank, 27,.Fig; 1, will begin to impart maximum progressive rotation and revolution to the tool. As the crank approaches its most elevated'position, Fig. 1, marking one half its travel the .tool will have been carried around the back of the heel to about the middle of the op 'osite side thereof, and as the crank diminls es its movement to nothin the cam 66 on the gear shaftwill' now li t the jack and heel to cause the necessary relatively straight traverse of the tool along the straight surface atthe opposite side of the heel and extending from about the middle thereof to the breast. These movements are exactly reproduced but in reversedorder durin theseco'nd half rotation of the crank 27 min which time the tool retraces its movement ack around the heel to its starting point.

I beheve I am the first to provide, among other things, a heel burnishin machi'ru having a presenting in di erent posi tions predetermined differently shaped sur faces capable of acting. predeterminatel upon or producing diiferentshapes of bee surface,-with meansfor producing a relativ change of position between theheel and toc to enable the latter to present these diflel 0d ently shaped surfaces to and for action up'o the heel and the patent here applied for intended to cover thisidea broadly WlthOl reference to any particular mechanical en bodiment thereof Bearing in mind that the shoe is held in the hands of the operative during'the shaving and also during the scouring of the heel, it will be understood that there are inevitably many though comparatively slight ciently good job ofburnishing with a tool that is-solid or rigid throughout. To correct this difliculty and to provide for obtaining as perfect a iece of ,work as may be, in the shortest poss1 le time, my invention provides for anovel construction of burnishing tool, in sections or members, which are relatively yieldingly supported, to permit them to rise and fall or play to and from the heel surface to which .they are presented the better to enable them to seek out and finish all portions of the heel surface, however irre lar the same may be.

l ether made in a single integral piece or in sections as'described, the tool will perform better work if caused to oscillate 'ver 7 the tool sections 72, 73 and 74, each slottedradiall to receiveand slide upon said stud screw 2". Each tool section'is supported radially .byya' spring 75, which tends constantly to press it outward into contact with the work. These sections are short in length, so that in the oscillations and travel of the tool they may play in and out radially and independentlyto enable them more or less completely to find the inequalities .in or adapt themselves to the heel surface acted upon. The ends of the sections are rounded or eased 01f as shown to enable them tomake the burnishing action.

easy contact with the work, and to prevent any mark upon the heel where the parallel rows of sectlons travel about the heel I have interlocked the adjacent sidejaces of the sections as at, 76, Fig. By making these lar, they do tions'frelative to each other'nor do they leave any open space which would interfere with The tool as shown toolswhich may be variousl devised to accomplish the same 'result an may, for-idenis merely typical of tification, be denominated a patterned tool, although it is evident that this or other character of tool may be employed in connection withother features of theinvention and that these features themselves may be variously used in conjunction or otherwise, as will-be obvious to one skilled in the art.

Toiimpart a top to bottom oscillation to the tool I'have provided the plates 70, 71, see Fi 10 with diametrically opposite ears, 77, w ich travel longitudinally in" arch shaped slots, 78, in arms,-79, that project forward from the bearing 14:, for the tool spindle: The axis of these slots is preferably coincidentwith the tool surface at the point where it contacts with the heel, so that if said tool be reciprocated in the general direction of its axis it will have imparted to it a swinging movement that will be equivalent torocklng or rollin it upon the heel surface from the top to t ebottomthereof. This action brings every point of the tool surface into effective contact with the heelversely of the heel at its line of contact therewith, thus permitting theed e of the tool to follow accurately the heel seat or rand line over or into which it laps as shown. To roduce this red rocation of the tool the bee plate 71 (see ig. 6) is provided with a threaded socket 80, that receives the threaded end of a socketed" head, 81. This head at its. rear side is provided with a I series of crown teeth, 82, that mesh with similar teeth in the end of bushing, 83. This bushing is splined within the tool spindle, 13, which is made hollow for the purpose, and at its inner end said bushing is supported yieldingly by a spring, 84, seated upon the shoulder end of a rod, 85,'lon tudinally movable within said spindle. T e leading end of said rod is universally connected with the socketed head 81 on the tool so that as said rod is reciprocated Within the hollow spindle, 13, it will cause like reciprocation of the tool, ,while permitting the tool to assume any radially angular position given it by the curved slots 78, described' As the tool is pushed forward the spring supported toothed bushin 83, follows it up to maintain its ,toothe engage- -ment therewith so as to cause rotation thereof'by and from said bushing at all times. At. its inner end said rod 85 is provided with a cam head, 87 which is fast thereon and betweeusaid head and the, end of the tubular surface, yet does not shift the tool transrspindle l3, is interposeda spring, 88, that.-

presses said rod normally rearward. Rotativelynmounted opposite said cam head, 87, .isia complemental cam, 89, faston a gear,

0, mounted upon an arbor loosely mol'nted n a bearing, 91, yoked over from the tearan idler, 92, from a gear, 93, fast on x (Fig. 6) referred to. The tra n ing, 14. This gear, 90, is driven throagll ter oscillates infront of it the cam face of the rod head', 87, oscillating in front of the cam, 89, on the gear, 90, will impart to said rod and to the tool rapid endwise reciprocations necessary to give the vertical or top to bottom rocking of the tool. These movements, like'the oscillations of the tool. follow the tool throughout the travel of the latter so that the action at all points around the heel is substantially uniform.
