MACHrNE Application, filed January 5,1928. Serial No. 244,747.

This invention relates to 'burnishing'machines and is herein illustrated asembodied in a heel burnishing machine of the type illustrated in Letters Patent -of the United States No. 743,988, granted Nov. 10, 1903, upcn the application of Charles ease, altliougliin various respects the invention 'is not limited to embodimentin heel burnishing machines. n f

In the operation of burnishing. the leather heels of both mens and womens shoes, machines of the type illustrated in the above mentioned Letters Patent have long been used successfully. These machines are arranged to apply a coating of carnauba wax by means of a rotary metallic burnishing tool having a coating of melted wax for application to the surface of the Work. This melted wax is supplied to the tool from a heated wax pot by means of a wax transferring Wheel. Such machines are also usually supplied with a cloth covered brush or pad,'a beading tool, and a polishing brush for use successively after the work has been treated by the burnisliing tool.` t `f One object of the present invention is to provide an improved burnishing machine by means of which the quality of work produced may be improved and the quantity of Work increased and which will be more convenient for the operator. j

To this end and in accordance with a feature of the invention, the illustrated heel burnishing machine is provided with a burnishing tool and a wax transferring wheel Vmounted for relative lateral adjustment so that they may be brought into that cooperative relation in which the best distribution of wax over the surface of the tool will be effected. Tn the illustrated arrangement the .Wax transferring wheel is mounted for axial adjustment with respect to the burnishing tool on a support which is rotatable about an axis substantially at right angles to the axis of the tool, to allowits lpositioning in the ultima relation to the tool, as well as being mounted for adjustment about an axis parallel to the axis of the tool, as has been customary in such machines, so that the Wheel may be moved toward and away from the tool.

, It will be understood that, as the vcontours of various heels presented to a heel burnishing machine differ, it has been necessary either to apply differently shaped-tools corresponding respectively to the contours of t differently shaped heels, or to adjust the contour of the burnishing tool itself when, for

example, the latter is of the type disclosed in Letters Patent of the United States rNo. 1,543,556, granted Sept. 27, 1927, upon my application. In either case, a longitudinal seo- "tion through the axis of the tool shows frequently, and especially the case of Louis heels, a contour such that the point of largest diameter lies between the ends.

n Another feature of the invention, therefore, which is especially adapted to this condition rbut is also useful for all contours, resides in the provision of a plurality of wax transferring'- wheels, dipping in a wax pot, and arranged to be brought into operative engage- 'Vment `with the burnishing tool upon opposite sides ofthe point of greatest diameter. In

f the illustrated construction the wax wheels are adjustably supported so that the wheels and the tool maybe relatively adjusted to bring them into proper interrelation, the wax wheels being mounted on a common axis and Varranged for simultaneous adjustment about a plurality of axes. This common axis is j our'naled in the wax pot itself andthe Wax pot is mounted for adjustment not only about an axis parallel to the axis of the tool so that the wheels may be moved toward and away from the burnishing tool to regulate the transfer lof-wax, but is also. mounted for adjustment aboutv an axis substantiallyV at right angles to the axis of the tool so that both whe-els may be brought into the desired relation to the periphery ofthe tool forV effective transfer of wax whatever its exact contour This arrangement enables the transfer of wax to the tool along strips lying at either side of the bulge of the' tooll so that the action of centrifugal force urging the wax to `thelpoint of greatest diameter will assist in thewax distribution over the surface. of the tool,

In accordance Withstill other features of the invention, the illustrated machine comprises a head and a base connected by a standard 'in which there yis an upright shaft, and the machine is provided with a plurality of tool carrying shafts in the head u on opposite sides of said upright shaft, oneo these being for the burnishing tool and anotliei' carryingr the pad and the brush. As illustrated, too, means are provided for interconnecting` the upright shaft with the tool carrying shafts which means are arranged to drive said tool carrying shafts in the same direction butv at different speeds in order that they slialliotate at the speed most suitable for the tools which they carry. As illustrated, one tool carrying shaft is surrounded by a sleeve extending over a portion of its length which sleeve is connected at one end to the driving mechanism, and at the other end is arranged to supply power to the mechanism by means of which vthe carnauba Wax is applied to and spread over the surface of the burnishing tool. Mechanism is also provided for interconnecting the sleeve with the tool carrying shaft which mechanism is constructed and arranged to impart an axial oscillation to the tool carrying shaft at it rotates said shaft, without, at the same time, oscillating the eeve. This said oscillation of the sha-ft carrying the burnishing tool avoids the production of tool marks as is well understood.

Still another feature of the invention resides in the provision of a protective cover for the Wax supplying mechanism which partially overlies the burnishing tool, and is provided With a hinged flap, the latter dropping down approximately to the surface of the tool to protect the operator from iying wax.

The operating tools of the illustrated heel burnishing machine, including an adjustable burnished tool 10 of the type shown and right and left hand twist respectively so that i described in Letters Patent No. 1,643,556 above referred to, a pad brush 12, a bead Wheel 14 and a polishing brush 16, are respectively mounted on a hollow shaft 18, and on solid shafts and 22 journaled in a head 24 of the machine, and these operating tools are so positioned that the operator may with the minimum change of position, apply the work in sequence to said tools so as first to apply a coating of wax to the heel and to rub it in, then to spread out this Wax and partially polish the coated surface by application of the heel to the pad brush 12, then to bead the heel by means of the beading wheel 14, and finally to complete the polishing of L.;

the Work by application to the polishing brush 16.

Experience has shown that it is desirable to drive the-various tools at different speeds byreason of their different functions but that they should be driven in the same direction so that the operator may with the maximum of convenience apply the work successively to said tools. The rotation of the tools is .effected by power, supplied from any suitable sourcc, such as an electric motor 26, which is transmitted to the tool carrying shafts through a drive shaft 28 mounted in the base of the machine and thence by means of a telescoping upright shaft 30 eX- tending through a standard 32. The shaft 30 is connected to the shafts 18 and 20, respectively, by means of skew gears 34 and 36 (Fig. 2). These gears are arranged With a the shafts 18 and 20 may both be driven in the same direction but at different speeds determined by coacting gears 38 and 40 connected to the shafts 18 and 20. In the arrangement shown, the speed of the tool shaft 18 is .slightw ly less than that of the upright shaft 30, while ythe speed of the pad carrying shaft 2() is slightly greater than that of the upright shaft. On the other hand, it is desired to drive the beading wheel 14 at considerably greater speed than that of the pad and, accordingly, its shaft 22 is connected to the pad carrying shaft 20 by means of spur gears 42 and 44 having relative diameters such that the speed of the shaft 22 is greater and an idler 4G is interposed so that the beading wheel shaft 22 will rotate in the same direction as the shaft 20.

In the arrangement illustrated for use when the electric motor 26 provides the driv- .i i

ing power, the motor sh aft carries a spur gear 48 which meshes with an internal gear 50 carried on the drive shaft 28 and the drive shaft 28 is connected to the upright shaft 30 by means of mitre gears 52. The position of the head 24 may he adjusted vertically with respect tothe standard 32 for the Convenience of' the operator, Without interrupting the shaft driving connections, by means of a screw' 54 (Fierl 2) bearing on the upper end ofthe standard and threaded in the head 24. This adjustment is permitted by the telescoping of the two .parts of the upright shaft 30, and after the head has been adjustedto the desired position, it may be clamped there by means of bolts 56 (Fig. 1). It may be desired to drive the machine by factory power, as

' from a countershaft on the ceiling or door,

and in that case the motor 26 is removed and a bracket (not shown) provided with fast 4trated, by means of a cartridge unit 60 mountedin the interior ofthe hollow tool carrying shaft 18 at the end of said shaft upon which the burnishing tool is supported. Current is supplied to said cartridge unit by means of leads 62 passing throughshaft 18 and connected at their outer ends by slip rings 64 (Fig. 2) and brushes (not shown) to a source of power. A control'box of any suitable construction, such as the control box 66 which is of the type set forth in Letters Patent of the United States No. 1,406,988, granted Feb. 21, 1922, uponxthe application of B. S.^Lee,-is supported upon a cover 68 for the head 24 and is provided with a control rheostat having a handle 7() and with a. switch 72. l It will be noted that, for the convenience of the'operator, the cover 68 is provided with a recess 7 4 in which a cleaning sponge or the like may be laid. v t.

To coat differently shaped heels, the periphery ofthe burnishing tool 10 will have various contours andy frequently, .as in womens work, will be bulged so that itssection of greatest diameter lies between the ends. The supply of wax to this periphery, as is customary in machines of this type, ycomes from awax pot having therein an electric cartridge heating unit 82 by means of which wax may be melted and kept in a fluidconditio'n. vThe melted wax in the waX pot 80 is transferred to the periphery of the tool 10 by means of a pair of constantly rotated wax transferring wheels 84 which are mounted upon a shaft85 (Fig. 7 j ournaled in' a bearing 86 integral with the wax pot 80.' The heat of the wax pot is transferred through the bearing 86-to thev wax wheels '84. Theprovisionof two waX wheels 1nstead of one is of advantage in any case and, especially so when the tool vhas a bulged periphery for then the waX may be supplied to thetool at points, i. e. along strips, separated a substantial distance in proportion to the length of the tool, and preferably lying upon opposite sides ofthe section having the greatest diameter. From these supplies the 7 wax will be carried centrifugally over the periphery of the wheel as well as being positively spread out in the customary fashion and as later described.

the position of the aXes of rotation of the tool and the wax wheels so that the wax wheels may be brought intol cooperative relation with the burnishing-tool at the point or points atf'which thetransfer of wax to the tool may be most successfully accom- 'plished so as to get an even distribution over the whole surface of the tool.V The positions of these transfer points will vary with the lcontour of the wheel andl frequently will be adjacent to the portions of small diameter. Inthe arrangement herein shown, this adjustment is accomplishedby providing an adjustable mounting for the wax pot litself in the form of a bracket 88 secured upon a rod 90 extending'laterally from the head 24 of the machinein a direction parallelto the aXis of the tool shaft 18. The bracket 88 is Provision is made for relatively adjusting disposed beside another bracket 92 which is clamped tothe rod 90 and'has an upwardly extending portion (notshown) which vis arranged to abut against a portion of lthe head 24 ofthe machine to resist` turning movementI of said bracket 92 and parts attached thereto. The bracket 92 also has va depending portion A94A arranged detachably to support a drip pan 96 (Fig. 1) as more fully shown and Adescribed in Letters Patent oftheUnited States No. 1,686,333,

granted July 19, 1927 upon the application of J. F. Standish. e

Adjustment-of the position of the bracket 88, and hence ofthe wax pot and waarv wheels 84 about the axis of the rod 90, so as to cause the wax wheels to move toward and away fromthe surface of the tool to vary the quantity of waX delivered to the tool, is effected by means of a slow motion means, such asa hand screw 98 which passes through vthe bracket 88 and rbears, against the body of.

.at right angles to the axis of therod 90, and

hence at right angles to they axis of the tool 10', by'mounting the wax pot 80 upon an upright stud4104which passes through a iiange in the bracket 88 and is threadedin the `bot- Irale 5 tion to the tool and enables the angular re lation between the axis of the wheels 84 Vand the axis of the tools to be varied in accordance with the shape of the tool so that said wheels 84 will coact evenly withthe tool 10. The arrangement is such that the exact position of the wax wheels with respect to the axis of the stud 104 may be adj ustably determined by means of a. slow motion means in the form of a hand screw 106 passing through a portion of the bracket 88 into engagement with one side of a depending flange 108 upon the bottom of the wax pot to push it in one direction against the tension of a spring to be later described. The wax pot near its rear end is provided with a depending guide plate 110, which is slotted for the reception of a flattened finger 112, formed as an integral extension of the bracket 88, thus forming an interconnection between the bracket and the wax pot to steady the latter and providing for the attachment of a spring 114 by means of which the wax pot is normally swung in one direction against the action of the screw 106. By manipulation of the screw 106, the

wax Wheels may be adjusted axially of theV tool to transfer their points of application of wax along the surface of the tool so as to get the most effective inter-relation regardless of the contour of the particular tool which is used. The adjustable arrangement of the dual wax wheel `mechanism makes it adaptable for all the various contours which an adjustable tool of the type described in Letters Patent No. 1,643,556, to which reference has been made above may be given.

It will be seen that the wax ot 80 is provided with a lateral cup 116 which o ens at its lower end into the interior of t e wax pot and is utilized by the operator for the reception of a wire or the like, by means of which small quantities of wax may be applied to the work for the repair of scratches and imperfections. A cover 118 is mounted upon the wax potand is provided at its forward end with a hinged, depending flap 120 which comes close to the upper side of the surface of the burnishing tool 10, thereby to protect the operator from flying wax. By this arrangement the de ending flap 120 and the ycover 118 may be t rown back together when it is desired to obtain access to the tool or to the wax supplying mechanism.

The, driving mechanism for the wax wheels 84 is eflected through an extensible shaft 122 provided with a plurality of universal joints 124 so that its operation will be unaffected by the adjustment of the positionl of the waX wheels. As a safeguard the'shaft 122 is also provided with a slip joint 126 (Fig. 4) so that the mechanism will not be broken in case 'slotted block connection 156.

an operator should try to start the machine before the wax has been melted at the wheels 84, as when the machine is being started in the morning. The slip joint 126 comprises a'casing 128 in which is secured a. cap member 130 att-ached to one part 132 of one of the universal joints 124. A short shaft portion 134 journaled in a bearing 136 upon the bracket 92 passes through one end of the cup-like.y casing 128 and has a head 138 surrounded by packing material such as leather, this head 138 being gripped more or less tightly to the cup-like casing 128 by means of aset screw 140.

The machine is also provided with a wax spreading brush 142 which, as illustrated, is constructed in accordance with the disclosure of Letters Patent No. 1,636,333, to which reference has been made above and which is arranged for reciprocation across the face of the burnishing tool 10 to spread out the wax which has been applied thereto by the wax wheels 84. To this end, spreading-brush holding mechanism 144 is mounted upon a rod 146 which is adapted to be reciprocated through a bearing' 148 formed integrally with a protective casing 150 which surrounds the portion of the shaft 18 adjacent the burnishing tool.

Motion is transmitted to the wax-wheel driving shaft 122 from a rotary intermediate member, here an upright jack shaft 152 journaled in said protective casing 150 and connected to the portion 134 of said shaft b means of mitre Gears 154. The jack sha t 152 is also connected to the rod 146 to reciprocatethe latter by means of a crank and In order that power may be supplied to the ack shaft 152 steadily but slowly to rotate it, said shaft is provided with a worm gear 160 meshing with a worm 162 which is formed on a sleeve 164 journaled in the head casing 24 concentrically with and surrounding the shaft 18. The skew gear 38, by means of which power is supplied from the upright shaft 30 to the tool shaft 18, is mounted directly upon this sleeve 164, being held there by any suitable device such as the set screws 166 and, by reason of suitablei enlargements or collars upon the sleeve 164, is held against lateral oscillation with the shaft 18. Thus the sleeve 164 and hence the jack shaft 152 for driving the wax wheels 84 and the wax spreading brush 142 are rotated steadily without oscillation of the sleeve 164 and without that variation which would be found incidental to the drive of these mechanisms directly from the tool shaft 18. On the other hand, the transfer .of power from the skew gear 38 to the'shaft 18 is eHected by means of a tongue 170 extending from a cam 172 which is secured to the shaft 18. This tongue 170 enters a slot in a hub portion of the skew gear 38 and hence is free to slide axially with respect l;

thereto. Axial reciprocation is imparted to the shaft 18 by the coaction of the cam 172 with a. roller 174f1xed in the head casing24 of the machine. The amount of axial movement is very slight, being simply sufficient to prevent the production of tool markings by the sections of the tool 10, and the curvature of the cam 102 is exaggerted in the drawings to make its function evident from an inspection thereof.

In order to avoid, so far as possible, thev spattering of wax -upon the operator, a suction hood 180, shallow so as not to interfere with free use of the pad 12, is associated with the brush pad 12, and this hood is provided with a receiving pan 182 at its lower end having a connection 184 by means of which an air suction pipe may be attached thereto. At the upper end of the suction hood 180 a notched ap 186 is provided by means of kwhich pieces of wax carried around with the pad 12 by centrifugal force are caught and'caused to drop into the receptacle 182 of the suction hood without being thrown upon the oper-v ator. The suction hood 180 is adjustably attached to lugs formed upon the bracket 92 by means of screws 188 lpassing through slots in the hood. The hood 180 is cut back as shown in Fig. 1 of thefdrawings in order to allow ready access to said pad wheel in applying work thereto and when it is desired to change the cloth cover on this brush.

The polishing brush 16 is also provided with-a suction hood 190 havinga pipe connection 192 at its lower end and at its upper end a fixed plate 194 extending toward the periphery of the brush in, a more or less radial direction for the same purpose as the Hap 186. This hood 190 is provided with a laterally extending flange 196, by means ofy which it may be attached to a portion of the head 24.

A treadrest 198 is adjustably Vsupported by means of a slotted ysegment 200. and a' clamping handle 202, tofassist the operator in lthe proper presentation of the work to the burnishing tool 10. It will be seen from Fig. 3 that the beading wheel 14 is provided With a pivotally mounted friction heater 204 arranged to keep said wheelconstantly hot so as to improve its effect upon the work.

In thek operation of the illustrated machine, after wax has been melted and applied to the burnishing tool, and the machine has been started, theoperato'r will present the heel of a shoe to the burnishing tool 10 with the tread face of the heel resting uponv the tread rest 198 and the periphery ofthe heel bearing againstthe burnishing tool 10. By

'turning the heel, all portions Vof its periph# face of the heel and partially polished. The i same operation will also effect an evening of the wax coating and the removal of surplus wax in ,case more than the desired quantity of wax has been applied by the burnishing tool y10. 'Ihe operator next, by applying theheel tothe beading wheel 14:, will cause a series of indentations to be made around the upper edgeof the heel adjacent to the rand crease for decorative purposes. He then will transfer the work to the polishing brush 16 whichis constructed of soft bristles so that it may be used to eect a final vpolishing of the work without injury to the upper of the shoe in case it contacts therewith.
