To all whom 'it may concern:

-Be it known that I, RALPH C. SIMMONS, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Operating Upon Heels, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for operating upon boots and shoes and more particularly to machines for operating upon heels, such for example as is described in my copending application for United States Letters Patent,-Ser. No. 491,785, 'filed April 23, 1909, of which the present application is a division.

ln breasting heels it is sometimes desirable for ornamental effect to breast heels by Cuts which are oblique to the longitudinal median lines of the heels. It is generally customary to have the breasts of the heels incline forwardly toward the outer side of the shoe so that a right heel will be breasted by a cut which is oppositely inclined to that of a left heel. I

An object of the present invention is to provide an improved machine for breasting heels which is adapted to breast right and left heels by cuts havingthe proper angular relation to the longitudinal median lines of 'the heels. Y

A further object of the invention-is to provide improved positioning means for loy eating the shoe with its heel in proper operative relation to the breasting knife.

With these and other objects in view the present invention contemplates the provision in a heel .breasting machine in which the shoe is movable to position the heel ofthe shoe in proper angular relation to the breasting knife of means for positioning` a shoe so that its heel will` be breasted by a cut havingthe desired inclination to its longitudinal medianline. The .construction is preferably such that right and left heels may be accurately positioned vin such relation to the knife that theywill be breasted respectively by cuts having equal and opposite inclinations. Preferably also the means for determining the right and left alinements of the shoe comprise gages arranged to have direct engagement with opposite sides of the shoe as withthis construction a shoe may be more accurately positioned with relation tothe breasting knife than would otherwise be the case.

lVhile in its broader' aspects the present invention contemplates the, provision of gages which are arranged to engage opposite sides of any suitable part of the shoe the arrangement is however preferably such that the gages are adaptedr to have contact with opposite sides of the heel, as owing said means, and the rounded end of the heel is restrained from transverse movement so that the shoe may be tilted about an axis which extends longitudinally of the knife in proximity to said rounded end to position the heel in the desired angular relation with the breasting knife. The means for limiting the tilting movement of the shoe comprise gages arranged for engagement with the opposite sides of the heel and to be adjusted equally and in opposite directions.

rlhe side gages or rests, as shown, are of short vertical length so as to engage the top portion only of the sides of the heel. This top portion may comprise atop lift which usually has the final shape of the heel whether or not the heel hasalready been f trimmed.

The means for restraining the, rounded end of the heel from transverse movement may comprise a member having inclined faces for engaging the sides of the heel, preferably in a plane substantially below the top lift of the heel of the inverted shoe, whereby the member cooperates with the other gages to prevent-rocking movement of the shoe heel under the action of the knife. This member which restrains the heel from transverse movement is preferably held resiliently in forward position and is moved Vrearwardly `by pressure of the shoe heel againstits inclined faces, thereby acting to one direction and a left shoein the opposite direction inv order to position the shoes in proper relation'to the knife, the extent of the ltilting movements of the shoes being respectively limited by the gages. As the gages are continuously sustained'in psition to be engaged bythe sides of a shoe it will be seen that in changing from a right shoeto a left shoe, or vice versa, no adjustment of the positioning device is required as it is only necessary for the operator to tilt a right shoe in a direction opposite to that of a. left until its tilting movement is limited by the gage corresponding to the shoe being operated upon.

These and other features of the invention will appear more fully from the following description when read in connection with the accompanying drawings, and will be pointed out in the appended claims.

vIn the drawings,-Figure 1 is a view in side elevation of a heel breasting machine Y provided with a shoe positioning device embodying the present invention; Fig. 2 is a v plan view of the positioning device shown in Fig. 1, looking upward toward the line 9-9 of said figure.

The frame 94 of the shoe positioning device shown 'in said figures is pivoted at 96 to the lower end of a slide 8. A projection 98 extending upwardly from the Yframe 94 is arranged to engage a bolt 14 of the holder and a spring 100 extending betweenV the holder and frame serves to hold the pro- Yjection 98 in engagement VVwith the end of said bolt. The frame 94 carries a plate 102 which is adapted to engage 'the tread portionof the heel of a shoe carried by the shoe support 6 to clamp said shoe in operative position. A shoe support 6 which sustains the shoe inthe path of the knife fits loosely inthe shoe, whereby a tilting movement of the shoe relatively to thev support is permitted 'so that the longitudinal media-n line of the heel may be positioned in an oblique relation to the knife. To limit movement of the shoe into Voperative relation Vwith the breasting vknife there is provided a gage 104 which is adapted to be engaged by the rounded end of the heel of the shoe, and is carried by a limiting plate 106 mounted for slidingmovement, in guideways formed inV the frame 94, in'a direction'substantially parallel with the line of movement of the shoe into operative position. A worm 108 rotatably mounted between ears projecting from Ythe frame 94, extends through an opening formed in the outer wall of one of the guideways and meshesy Vwith teeth 110 formed upon one of the edges of the plate 106. The worm 108 is constructed to be manipulated by the operator so that the limiting plate 106 may be conveniently moved into different adjustments; A centering slide 112 having a V-'shaped recess adapted to center the rounded end of a heel with relation to the gage 104 is mounted in the lguideways below the plate 106. VA torsional s rino' 114 havinO one endsecured in fixed relation to the frameV 94 and its other end engaging a stud 116secured in the slide 112 serves to yieldingly press the Vlatter toward the heel. A pin 118 formed to be inserted in any one of a seriesV of openings 120 in the centering slide 112 is vadapted to engage the limiting plate 106 to limit forward movement of the slide. lVth the construction above described the rounded end of the heel ofthe'shoe maybe accurately centered by the slide as said heel is moved toward the gage 104 which limits its movements.

manipulatingthe worm 108 the gage 104 may be adjustedso that the length of the heel as determined bythe breasting operation will be accord with the width of said heel. y f

In the present device therounded end of a heel inoperative position is restrained* from lateral movement by the V-shaped recess in the plate V112 so that the shoe may be readily tilted about an axis in proximity to said rounded end, to position the heel in the desired angular relation to the breasting knife. To limit the extent of this movement there is provided means for limiting lateral movement of the breast end of the heel in opposite directions respectively. According to a convenient construction two gages 122 are arranged upon oppositeV sides of the pressure plate 102 in positions to Vbe engaged by the edges of the vheel in proximity to its breast corners. The' gages 122 respectively depend from gage slides 124 arranged in a guideway formed in the plate 102 transversely of the line of movement of the heel into operative position. The slides 124 are interconnected by` aY rightland left hand threaded screw 126 having a milled head 128 adapted to be manipulated by the operator. The plate 112 is located below the plane of the rests or gages 122 a distance which, as shown, is approximately half the height of Y vWith the rests not only to limit vlateral turning movement of the heel but also to prevent rocking of the shoe under the action of the knife. The operation of this device will be readily understood from the foregoing by ,those skilled in the art without further description thereof.

It will be seen that in accordance with the present invention a shoe and an operatingV .be accurately performed, and that the work will be of uniform quality.

Although it has been herein stated that the present device 4is adapted to relatively position a shoe and an operating tool it will y however be understoodthat the invention is may be employed not only to position shoes `article other than an operating tool.

Moreover the present invention is equally applicable to devices for positioning lasts or to devices for positioning any article having a shape similar to that of a shoe or to any partthereof.

It" will be further understood that although the present device is employed to.

.relatively position a shoe and an operating 4tool the invention is applicable to devices for relatively positioning a shoe and stine or eXampleewhere it is desired to relatively position any two parts of a shoe a device embodying the present invention could be readily employed to effectv this result.
