Application ale-arme a9, 190s. serial No. 440,816. l

The principal objects of the'invention -are to provide a reversible die which can be operated from either side so. as to cut rights and lefts; to provide a construction in which a handle or block for receiving the blow or pressure during the cutting operation will be firmly secured to the die in such a manner that the points where the greatest strain comes will consist of removable pieces that can be replaced when Worn or damaged; to`

provide an improved form of guard for the die which will be strong and` light, will be reversible, and will have means for returning the die to central position after it has been operated; to provide a detachable tipforming die whichcan be readily' applied to a short vamp die; to provide convenient and simple markers for a die; and generally to improve land simplify the construction and operation of cutters for dying-out blanks from sheet material such as upper leather for boots and shoes..

Further `objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings which show a preferred form of the invention, and in which-' Figure l is a plan thereof; Fig. 2 is a sectional view on the line 2 2 of Fig. l1. Fig. 3 is an end elevation looking in the direction of the arrow 3 in Figpl; Fig. 4 is a side elevation in the direction of 'the arrow 1 of Fig. 1; Fig. 5 is an elevation of a portion of the inside showing one feature of the invention; Fig. 6 is a sectional view. of.

thesame; F ig. 7 shows part of -a blank which has been marked by the markers illustrated in Fig. 5; Fig. 8 is a perspective view of a detail; and Fig. 9l is a fragmen tary plan of a detachable vtip die and guard.

The invention is illustrated in a form comprising a reversible die 10` having top and bottom cutting edges, so that'the die vided with a frame 11 consisting of a plurality of arms, each-secured to the die so that a block or handle 12 may be inserted in a perforation 13 in the frame on either side, so as to receive a blow from a hammer or pressure from a press, to cause the die to cut through leather or similar material. In the case of handle dies it will be understood that a strong frame is required, and that it must be firmly secured to the die. Ordi.

narily frames of this character are secured through the die or otherwise secured directly to it, and it has been found in practice that su`ch a construction is. not very. .durable on account 'of the hard usage to which the device is put. The screws or other fastening devices soon wear out and also wear or break the walls ofthe die, so that the whole device has to be thrown away before the die itself has begun to wear out. In order toavoid this, and at the same time provide a firm construction, the die is provided with a series of perforations 111 Athrough the walls thereof and relnovable pieces or inserts 15 are placed inl them at the' ends of the arl'ns of the frame and screwed to said ends. As the pieces 15 exactly lit the perforations 14, 'and as they are firmly secured to the ends of the arms,

it will be seen that a firm attachment of the frame to the die is secured, and yet if the screws or holes wear it is necessary only to replace the pieces 15. These -peces have a long bearing surface on the top and bottom 'of the pel'forations 14, so that the latter do not readily wear outor get out of shape. It

`will be understood, of course, that the die and frame are both reversible, so that they can be operatedfrom either side.

ln order to properly hold and guide the diei and guard its cutting surface against accidental injury, a guard or holder 20 is provided. rlhis guard corresponds in contour tothe outside of the die, and it is formed in such a way as to secure lightness of construction: witheut sacrificing -strengthfl This-may be effected by making the "guard l of'a more, or lessopen character, preferably -vamps both with and without` the toe tip, l.the guard is provided with aremovable bowshaped member 26 at the front, and the die4 with a removable piece 27 at the same point. The bow-shapedmember 26 is fastened to the' guard 20 by angle pieces 28. Thej main part ofthe die which is shaped to cut out marginal edges of the vamp has a xed bridgey member 29 which is not' provided witha cutting edge, but which constitutes part of the die to receivethe arms of the frame and to hold the latter on the die.

When it is desired to change from the form shown in full lines in Fig. 1 to thatshown in dotted lines, the parts 26-27, and. 28 are removed and the toe tipl cutting die is mounted in position. -This 'consists of a cutting member v30 shaped to cut the mar# gina] edges of a Vtip and a frame piece 31, the latter being secured -by means of screws orbolts or in any other convenient manner to the bow-shaped piece 29.- Outside ofthe cutting member a removable uard piece 32 is secured to the main guar by means of cleats 33 or the, like and proper fastening devices.

For the purpose of providing marks to indicate the size of the vblank cut out and the proper location for the line of stitching for the tip, the dieisprovided with t'wo double-pointed markers or punches 34 .and 35, each-one movable with the die, but adjustable along the same so as to providefor changing its position. The marker 34 is designed to show simply where the seamis to appear when the blanks arestitched together or the amount by whichthe 4tip should overlap the vamp, and therefore 1s provided with pointed ends so as to make a small lprick mark on the leather. The marker 35 is for indicating 'sizes and is provided with a cuttingedge at each end of some characteristic shape to distinguish it from the mark made bythe other die. Two or more of the markers 35 may be used in order, to indicate different sizes. It :will be understood, of course that the diiferent sizes may be indicated either by the shape of this marker by the number which. are employed. Both markers are mounted by means of bolts or screws 36 a. slot"37 on a bar-or plate 38 which is fixedv to the die and movestherewith. The cuttingV edges or points of the markers are in the same plane as the cutting edges of the die. These markers are conveniently mounted on the inside of' the die near the Vbow v shaped piece .29.V v

The provision of .longitudinally adjust' able markers isl of great advantagein combination with a die adaptedfor cutting out either short Vamps or full Vamps since it is frequently desirable to shift the location of the toe tip seam in changing from a short te a full vamp.
