A Application filed November 16, 1914. Serial No. 872,461.

To all whom it mag/concern:

Be it known that I, J oHN F. STANDISH, a citizen of the United States, residing f at Winthrop, in the county of Sufiolk and State of Massachusetts, have invented -cer tain Improvements 'in Blank-Holders, of w hich the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawingsindicating like. parts in the several figures. I v V This invention relates to a blankholder and, more particularly, to a holder, for'retaining a top lift or. heel blank in position to be attached to a shoe ina heeling machine.

The object of the present invention is to provide a heel or top lift holder with mech anism permitting the properv location and holding of blanks of an unsymmetrical contour such, for example, as characterizes a right or a left heel. It-will be understood that the breast edgeiofa right or left-heel is oblique to the olongitudinal central line of the heel, the inclination for a right heel being opposite tothat for a left heel.

An important feature of the invention consists in aheel or top lift holder provided with gages constructed and arranged to engage the edges ofa blank; one ofthe gages being invertible relatively to the remainder if the holder andso formed that byits inversion the holder is adapted to position and retain blanks of a differentcontour.

. The embodiment of the invention herein shown and specifically described comprises a rear gage formedto engage opposite sides of the curved end of a heel or toplift and an oblique breast gage held yieldingly toand arranged to engage the breast edge of theblank at a plurality of points, preferably along its entirelength.

In order to be most effective in practice, it is desirable that the construction of the holder be such as to accommodateheels or top lifts of either of the contours which characterize a right-and a left heel respectively. In accordance with the presentinvention, the breast gage is arranged for adjustment to permit a blank of either form to be held properly. o

In holdersv of this class, it is desirable that it shall be possible to make the change in adjustment from right to left, or vice as possible and that the construction be of the utmost simplicity compatible with the object sought to be attained. I have secured the desired results by constructing a breast gage'in the form of a, bar having parallel edges, formed to correspond to the contour of the breast edges of a right and a left heel respectively. I mount the bar in a manner to permit it readily to be inverted, and am thusable to changethe adjustment of the holder'from right to left, or vice versa, practically instantaneously by a single, simple movement. A breast gage embodying the present invention maybe constructed to accommodate blanks having breast edges of any desired contour, and I believe that the blank holder of the present invention is the first in the history of the art capable of conforming to both right and left blanks, the breast edges of. which are formed as ogee or reverse curves. I

The holder shown in the drawings is of the, same general type as that illustrated in U. S. Patent No. 884,513, to B. F. Mayo,

granted Apr. 14,1908, but it should be understood'that this particular type of-holder hasbeen selected only for convenience in lllustration; and that the invention is not limited in its applicationthereto, but is cav pable of embodiment in blank holders of various forms. f Y

I Invthe drawings: v i

Figure 1 is a plan view of, a' heel or top lift holder embodying the present invention showing an unsymmetrical blank held in pla i 7 1 Fig. 2 isa view, similar to Fig.1, show ing a blank with a breast of reverse obliquity in the holder w Fig. 3 is a view, similar to Figs. 1 and 2, i

showing a holder arranged for unsymmetrical blanks having a difierent contour from those showninFigsl and 2, and

Fig. 4L is a front elevation, partly in section, showing the construction and mounting of the breast gage. T

' Referring to the drawings, 10 represents a plate upon which the elements of. the blank holder, are mounteoL A-stationary block 12 is secured tothe plate 10, and init are formed guides in which the shanks 141 and 16 of the rear and breast gages 18 and 20, respectively, are mounted for sliding movement. i

' ohored in ny one of a series of holes 32 in a case ofthe plate 10, t6 provide for adjustment (if the tension of the spring. The spring 30, as will be seen, tends to draw thebreast'gage 20' toward the rear gage 18, for the urpose of holdin' the blank 34 in position between the sai gages. I f

.The o'onstruction 311st described is si1bstantially similar to that disclosed inthe patent-hereinbefore referred to. .According.

to the present invention that part of the breast gage 2'0 yvhioh-en ages the blank is net norinalto the ee-ntraI longitudinal axis ofth holder but lies in a general directionoblique thereto.- By this arrangement the holder is adapted to retain an unsyrnmetri'al blank, such as a right or left toplift or heel having an oblique breastedge, in cor-.- reet'position for proper attachment, to a shoe. The contour of the breast gagewill preferably be made to correspond to the sha e (if the particular blank, to be handled, tha shown in Figs. 1 and 2 bein in-the form of an ogee, oireversecurve, as in the What are known to the tradeas an-. at ain heels. The breast gage shown, in F1 3 is; formed tolocate properly a right orhettblaak having a straight breast ed e, or one having a simple concave curvature.

The opposite edges of'the breast bar 20 are parallel and the gage isformed with a cylindrical extension 36 which enters a bearihg 38 formed. in the end, of-theshank 16. A serew 46,.threaded in the end of the cylindrical ektension 36, retains the breast, age in its bearing and permits rotation o :the gage about the akis of the said extension; The freeend of the gage 20 is formed with a: tongue which slides in a guide .42 secured to the plate 10. The gage also rests upon the plate 10 and by its sliding engagement therewith, and by the guide 42, rotation about the axis of the cylinder 36 is normally prevented; but. when it is desired to change 7 from the right top lift or heel, shown in ig. 1 to the left top lift or heel, shown in Fig.2, the. breast gage maybe drawn forward against the tension of the s ring into the dotted line positionof Fig. 2, where it I is free from the plate 10 and the guide 42 and may be easily and quickly turned about the aiiis. efthe cylinder 36 until it is inverted, whereupon the contour of the blank engaging edge of the gage is reversed. and

it is adapted to hold a left top lift or heel.

Upon being released, the spring 30 draws the gage back into the guide 42 and it is held from rotationas before.

In F ig. 3 the breast gage is shown in solid and dotted lines in the two positions for engagement with left and right blanks and, except for the shape of the breast line, the construction is substantially the same as inFigs. 1 ancl'2'.

It will be observed that by making the gage 20 reversible by inversion its opposite edges may be formed to fit a pair of blanks having breast edges of any form, however complicated. A holder embodying this invention has no loose, separable, parts liable to beooinelost or dama ed, and the'desire d resultsare secured with the utmost simplic: ity and ease of manipulation. I w

;Having described my invention, what I claim as new and desire to secure by Let? tersPatent of the United States is: 7

1. A heel or top lift holder having a gage for engaging one edge ofahe'el or top lift, a relatively invertible gage for engaging the other edge of the heel or top lift, and means for effecting relative approaching movement ofsaid gages, to seize a blank between them.

2. A heel or top lift holder having a breast gage invertible relatively to the remainder of the holder, said breast gage being -'constructed and arranged to conform to the breast edg'es of blanks having breast edges o f clifferentcontours' by engagement with said edges. 7 p t 3. In a blank holder of the class described, a plurality of gages arranged to retain a blank in a predetermined position by engagement with the edges ofsaidblank, one of said gag s being invertible telatively to the other, about-an axis extending transversely offlthe holder, to :an alternative blank engaging position, v v V 4. In a, holder for heel or top lift blanks, a, pairof horizontally oppositely arranged relativelyunsymmetrical gages, one of said to the contours of right and left blanks havcurved edges in said two positions, respectively.

7.1 111 afdevi'ce of the class described, a single blank engaging member haying different blank engaging portions conforming respectively to the breast contours of right and left heels orto'p lifts having curved breast edges, 7

8; In a deviee of the elas's described, a

single blank engaging member having blank engaging portions conforming to the breast contours of both right and left heels or-top lifts having breast edges in the form of ogee curves.

9. In a heel or top lift holder, a rear gage, and a breast gage reversible by inversion and having opposite, parallel, Work engaging portions.

10. In a heel or top lift holder, a rear gage and a breast gage having two parallel, curved, Work engaging edges.

Copies of this patent may be obtained for five cents each, by addressing the 11. In a heel or top lift holder, a breast gage having a plurality of blank engaging edges movable, respectively, into positions 15 of reverse obliquity relative to the longitudinal central line of the holder.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
