1.0 face of the heel, meaning the surface to which the top lift will be attached, is the last one to be formed. The angular relation between the tread face of the heel and the attaching face thereof and the vertical distance or height theree between the important factors in determining the characteristics of the heel, and having once been determined, may not, be disturbed without serious likelihood of spoiling the style of the heel and making it unsuitable foruse in shoes of even rather low grade. It becomes desirable, therefore, from the viewpoint of the heel manufacturer to facilitate detection of alterations oftheheels in an attempt to make vthem'fit a last for which they were not intended with the consequent'likelihoodof producing an ill, fitting heel which if used, may seriously injure the reputation of the heel manufacturer. c I A i To overcome this danger the present invention makesprovision for marking the freshly prepared tread surface of a heelsubsequently to and as an incident of the heel grading operation. The invention is not limited, however, to embodimentinheel grading machines. 7

Heel grading machines arecommonly provided with an oscillating work carrier on which each heel positioned and by means of which it is presented to agrading saw, theoperator holding the heel on the carrier andreleasing it therefrom so feature of the invention relates to a displaceable markingdevice arranged to .be displaced so as not to interfere withlthe untreated heel whenthe latter isbeing presentedtoa grading saw'and positioned in'the pathof -movementjof andto markthefreshly prepared tread surface of the heel subsequent tothe grading operation.

Still other features of the invention reside in novel carrying mechanism for a marking device arrangedyieldably to support the marking device in the path of movement ofthe tread face of a that it may fall into asuitable receptacleafter the. grading operation; With this in View, one.

enclose an ink roll coacting with the marking de-- vice. Asillustrated also, the carrying mechanism providesfor adjustment of the level of the device and for adjustment to bring it. into the plane of the saw and allows thewhole marking device to be readily moved into inoperative position when desired and as easily returned to its operative position. r

I In the accompanying drawings, 7

'Fig. 1 is a plan view of a grading machine and its marking device i Fig. 2 is a perspective view of a heel looking at the tread surface thereof andshowing a marking thereon; I

, Fig. 3 is an enlarged plan view of the marking device; and e f Fig. 4 is a front elevation thereof together with its supports. I

The heel grading machine, a complete description of which will be found in the Knight application, to which reference has been made above, comprises a frame 10 in which there is journaled a rotary grading saw 12 and on which are mounted supporting brackets 14. for a shaft 16 securedto which is a swinging heel carrier 18. I This carrier has an ,adjustably positioned plate 20 against which the attachingsurface of the heel, is rested anda breast surface engaging arm 22 and is provided with a weight 24 to return it, when released, to a vertical position at right angles to that illustrated in Fig. 1.. The operator will position aheel against the plate 20 and the arm'22 and, holding itthere with his fingers, will swing the carrier to I move the heel in an arc intersecting the circuinference of thesaw 12 so that a portion 26 of the heeL hichmay have a dowel .pin 28 projecting ,therefrorn, will be removed and a tread surface 30 produced upon the heel in exactlythe de ably determined by laterallydisplacing the shaft 16 by means of a handwheel32 as described in said application.

Referring now more particularly to Figs. 3 and i 4, it will be seen thatthe marking device or wheel 34, embodying a peripheral band of rubber with type faces thereon, is freely rotatable in a recess 36 within a carrier 38 which is secured by a set screw 40 (Fig. 3) to the upper end of a stud 42 (Fig.4)- This stud passessubstantially verti cally through an angle piece 44 pivoted at 46 upon an, arm 48 adjustably secured to a bracket 50; This bracket 50 is bolted to the frameiO of the grading machine and provision is made fora vertical adjustment of the arm 48by means of a clamping bolt 52 passing through a slot 54 in the loo bracket 50 to bring it into the path of heels mounted in the swinging carrier 18.

The marking device is arranged to be normally held in the position illustrated in Fig. 3 by means of a coiled spring 56 surrounding the stud 42 and having one end attached to the angle piece 44 and the other end to a nut 58 secured to the lower end of the stud 42. This permits displacement of the heel carrier 38 of the marking device when it is engaged by the dowel pin 28 or by a projecting corner of the portion 26 of a heel mounted in the carrier 18 and being presented to the grading saw 12, said marking device when displaced occupying the position indicated in dotted lines in Fig. 1. As soon as the heel is carried in its swinging movement toward the saw past the marking device the latter will swing back to a position where the marking wheel 34 lies in the path of movement of the treated surface 30 upon the heel 25 as the carrier 18 is allowed to swing back to vertical position. As a result the inked type upon the marking wheel will move across the surface 30 and produce a mark 60 thereon, which mark, of course, may be varied and arranged to satisfy the needs of any particular heel manufacturer.

Associated with the marking wheel within the recess of the carrier 38 is a pivotally mounted ink roll 62 of felt or the like which is saturated with ink and which rolls over the surface of the marking wheel 34 as the latter is turnedby its engagement with the heel. The position of the marking wheel 34 when engaged by the heel is resil-' iently determined by means of a spring'member 64 having an inturned end 66 and secured to the angle piece 44 by means of a screw 68 anda pin 70. The spring 56'serves to return the marking wheel 34 and its carrier 38 into the position determined by said spring 64 and the spring 64 provides enough yield so that there is no danger of injury to the marking device as a result of engagement by the heel 25.

Protection of the marking device .and ink roll from falling dirt such as sawdust is afforded by a cover 72 at the rear side of the carrier 38 and a cover 74 at the front side thereof. At its upper edge, the cover 74 has a folded-over portion '76 overlying the top surface of the carrier 38. This overlapping portion 76 is slotted at 78 for engagement with a clamping screw 80 and the lefthand end of the cover 74 is curled around a pin 82.

A finger screw 84 extending between the angle piece 44 and the arm 48 providesfor adjustment of the angular relation between the marking surface of the wheel 34 and the plane of one side of the saw 12, thus enabling the marking device to be brought into correct markingrelation to thefreshly prepared tread surface of a heel mounted in the swinging carrier 18. In order that the marking device maybe moved readily to an inoperative position when it is not desired for use and as readily returned to its predetermined operating position, the screw 84 passes through a slot in the upper end 86 of the bracket 48 and is held frictionally in this slot by means of a spring 88 surrounding the screw and pressing against a convex washer 90 engaging the side of'the slotted end 86 of the bracket 48. When it is desired to displacethe marking device by swinging the block 44 around the pivot 46, this may be done simply by grasping the screw 84 and pulling it out of the slot in the upper end 86. When the marking device is returned to marking position, the convex faces of the washer 90 and of the lower ide of the head of the screw 84 facilitate the reengagement of said screw in the slotted end 86.

When it becomes necessary to apply ink to the inking roll 62, access thereto can readily be obtained by loosening the screw 80 and sliding the cover plate 74 to the left so as to disengage it from the pin 82, after which the cover plate can be either completely removed or swung around the screw 80. If it becomes desirable, the abutment spring 64 can be dropped out of position by springing it off the pin and turning it in a counterclockwise direction on the screw 68.

It will be understood that marking tools of other sorts may be substituted for the rubberfaced type wheel 34 illustrated herein. It may be desired not to apply an inked mark but rather to make an indentation in the form of lines, dots, etc.,' by means of a knurling tool, for example, which will escape notice by persons other than the heel manufacturer. Further protection against duplication of the mark may be secured by utilizing peculiar or imperfect type. When an inked mark is employed, the color of the ink used may indicate the month or season when the heel was graded.

The operation of the device will be apparent from the previous description and it will be seen that it is entirely automatic, requiring no thought from the operator of the grading machine and needing attention only at rare intervals when the supply of ink is-exhausted.
