To all whomit may concern .1

Be it known that I, THOMAS LUND, a citizen of the United v States, residing at Beverly, inthe county of Essex and State of Massachusetts,have invented certain Improvements in Heel-Burnishing Machines,

7 of which the followingdescription, in connection with the accompanying drawings; is a specification, like reference charactersjon the drawingsindicating like parts in the several figures. v 5 1 f V p 1 7 This invention relates to a heel burnishing machine and more particularly to mecha nism for guiding a shoe relatively to the burnishing tool. Atypical heel: burnishing machine embodyingfa rotary heel burnishing tool is illustrated in the patent to Pease No. 743,988. In machines of'that type, the rotary burnishing'tool is provided with a circumfer ential'work surface havingfa contour conforming withthe cross-sectional contour, of the heel to be burnished. 1A tread rest is usually provided against whichthe top lift ofthe heel is rested, as the latter is applied to the tool and' this rest maybe fixed in different positions. Such arrangements, however, take no account .of the fact that in certain types of heels there is a material difference in the. height of the heel, at its front and back 'with the result that if the tread rest is properly adjusted to enable the tool to be applied throughout the height of the heel at itsback, it will be. applied to a portion of the upper of theshoe near the front of the. heel. On.the'othenhand, if the tread rest is so. adjusted that'itis in proper position for the heightof the front of the heel, obviously it will not permit the whole of the heel tobe waxed orburnished.

In order to. overcome thisdiiiic'ulty, I have devised novel mechanism for a machine of the type described comprising means for positioning ashoe to holdthe. rand crease edgeof theheel opposite to one adge of the burnishing tool asthe heelhis turned in being presented to the tool. This is preferably accomplished by meansof a relatively fixed rand crease guide plate mounted adj acent one edge of the circumferential work surface ,of the tool and forming-a fulcrum about which the shoeslmay be rockedfion 7 an axis substantially tangential to the rand crease as the different portions ofthe contour surfaces of the heels are presented to Application filed Meet 27, 1917. Serial No. 157.759.

Specification of Letters Patent. Ap

n The mechanism, which I have devised, also includes means movable transversely of the tool and automatically maintained in engagement with the tread of theheel to steadyit. Such a mechanism provides for variations in *the height of various parts of the heel while insuringtha t the, upper is fully protected and the heel firmly supported during its application to the burnishing tool. rlflvidently the,rand crease gu de may be used independently of the treadrest. L -f v w or a fuller understandingof myinventron, reference may be had to the following specification taken in connectionwith the accompanying drawings in which, 7 I Fig. l is a perspective YieWT of one embodiment of my invention;

plan view of a portion thereof;

Fig. .tis a fragmentary view showifig a heel in two positions. I V I Machines of this type comprise a support ing column 10, on which is mounted a shaft carrying a rotary burnishing tool v12 which is driven by means of suitable gears lt. A wax spreading brush 16 insures an even spreading of the wax over the work surface 20 comprising. 7

be 'providedwith. a flatintegral w 7 lug 22 which engages a correspondin groove- 24 in a; supporting bracket26. The

bracket 26 is adjustably bolted to a rod 30 carried upon-the frame of the machine. The guide-20 is held uponthebracket 26 by means ofa bolt- 32 and wing-nut 34c and ment of the bolt 32 and therand guide 20 transversely of the bracket. 'It will be seen from 3 that the guide 20 is suitably recessed 'to prevent interference with ,the end of the burnishing 130013 shaft as the former is adjusted on the bracket 26.

. a slot- 35 in the bracket 26 allows for move 7 105.

A tread rest 36 is provided which may conveniently be of the form illustrated in the patent to Pease No. 1,19?,850. This tread rest is mounted upon a slide 38 by means of a. bolt 40 and is angularly adjustable with relation to the work surface of the burnishing tool in the manner illustrated in the latter patent. The slide 38 is dove-tailed to a bracket 42 on the machine frame and is provided with a depending lug 44 carrying a bolt 46 having a stop nut 48. This nut co-operates with a lug 50 upon the bracket 42 to adjust the normal position of the tread restand a spring 52 encircles the bolt &6 and is interposed between the lugs 44: and 50 so that it urges the tread rest toward the guide 20.

The operator wil1 apply a shoe to the burnishing tool by pushing the tread of the heel against the tread rest 36 until he can 10- cate the rand guide 20 inthe rand crease of the shoe. The resilient mounting of the tread rest enables it to accommodate itself to variations in the height of the various parts of a heel, as shown in Fig. 4, so that the burnishing action is applied to all parts of the surface thereof. At the same time the upper is fully protected by reason of the action of the rand crease guide in definitely locating the shoe relatively to the burnishing tool.

Inasmuch as there is relatively little difference in the dimensions of the small ends of different burnishing tools, the curvature of the edge of the guide 20 will always be similar to that of the tool. Besides this, the guide may be adjusted longitudinally along the rod 30 and transversely in the slot 35 as 'mzg be desired.

aving thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A rotatable burnishing tool provided with a circumferential work surface to treat a shoe heel throughout its height and a thin hat guide plate fixed transversely to the axis of rotation of said tool and arranged to form a guide to enter the rand crease of a shoe and forming a fulcrum about which the shoe may be rocked on an axis substantially tangential to the rand crease to present the different parts of its heel surface to the burnishing tool.

2.
