DIE.

To all whom it may concern:

Be it known that I, HARRY ZIMMERMAN, a citizen of the United States, residing at Fremont, Sandusky county, Ohio, have invented new and useful, Dies, of which the following is a specification.

This invention relates to features of com mercial economy in the cutting of materials.

This invention has utility when embodied in connection with dies for multiple fabric cutting by the action of a member of blank form driven into the material upon a cutting block.

Referring to the drawings: Figure 1 is a plan view with parts broken away of an embodiment of the invention in a die for hand covering blanks; Fig. 2 is an enlarged section on the line II-II Fig. 1 looking in the direction of the arrow and showing a spill device for the cut out material; Fig. 3 is a section on the line IIIIII of Fig. 1 showing a similar spill device; Fig. 4 is a fragmentary end view of the die of Fig. 1 showing the position of the handle and trimming device; Fig. 5 is a fragmentary plan view of a series of dies for thumb backs or half fourchettes, a blank in hand coverings; Fig. 6 is a fragmentary view of a blank fourchette grouping in hand coverings; and Fig. 7 is a bottom plan view showing the merging of three cutting lines for mutual stiffening and ample clearance.

The die 1 is integral and has the endless wall extending from trimmer 2 on one side to the trimmer 2 on the other and back to inclose as shown a plurality of blanks, laterally adjacent. The die is provided at its extremities and adjacent to the trimmer with handles 3 rigid therewith, which handles 3 have drop portions 4 to permit of ready retention of said members when hung upon a pair of bars. With these handles 3 disposed as shown below the plane of the cutting face of the die form 1, there is no danger from accidental crushing of the hands or fingers in normal setting or removing of the die form. The blanks for the cutting dies are so disposed in the common integral die with slight modification from normal or regular contour as to present therebetween single walls 5 provided with a common cutting edge for the glove palm and finger blank 6 and the laterally adjacent finger back 7, said cutting edge having a contour intermediate of the normal contour of the two adjacent dies. The

Specification of Letters Patent.

glove blank 6 is shown as having intermediately thereof circular thumb opening 8 providing therein an endless cutting portion, while to maintain the efiective contour of the blanks 6 and 7 there is the continuously integrally walled opening 9 therebetween. These continuous cutting portions 8 and 9 readily fill with material cut and having their walls so closely situated tend to congest material therein. To obviate this trouble the wall 10 is of less height to provide an opening below the top of the die from which opening the cut material may readily spill. In each of these instances as to endless cutting portions 9 and 10, the material from these openings is waste as to the particular blanks of hand covering being out. To facilitate the removal or spill of material from these endless cutting portions and out of the openings 10, there is provided on the opposite side to the opening 10 the incline 11. I

In normal form the blanks 6- and 7 would approximate, by gradually approaching at one or two points, long tapering cutstherebetween of waste material. In operation the driving of dies in the many thicknesses of fabric would place excessive strain upon adjacent or converging walls, which if rigidly connected would tend torupture said walls. Applicant has solved this problem efliciently without detracting in any way from the primary purpose of the blanks by contributing to the blank forms or cutting dies the most troublesome portions of these narrow cuts. This is done by causing the form of the die, likewise the blank, to depart from normal form and to do so abruptly upon a normal regular line so that it is ignored in sewing up or using the blank and in no wise detracts from the purpose or regular efficiency of the blank. The cutting dies accordingly produce cut pieces of contours adapted to normal seaming. All of this departure from normal blank form may not be of the nature of an independent mally, leads off, in the instances shown, as a curve soon assuming the normal direction line for the blank.

The dies may be operated by placing under a press so that the press actuated faces 16 upon the top of the die Wall may positively drive the cutting edge 17 therebelow directly into and through the multiple fabrics to be converted into cut portions 18.

The die 19 of Fig. 5 is of form for a thumb back or half fourchette to contribute to maximum economy in cutting. The form thereof is modified to approximate four sides 20, 21, 22 and 23 so that there may be common cutting walls 5 therebetween and that in the progress of the cutting die the staggered relation will regularly interfit for maximum of waste reduction. Near the meeting of the three lines of cutting these dies show abrupt merging of the third line into the other two to eliminate narrow waste strip portion and its tendency to work disaster to the die. Similarly in the fourchette blank die 24 the long taper of the waste is eliminated, which taper or normal line of direction 25 of the die is shown here as well as in the other views. As shown in Fig. 5 when not cutting waste but when cutting regular blank portions, the spill device may be incorporated. This device has especial value when the forms out are small.

The unitary, one-piece and rigid character of the die permit it to be made of minimum weight, and in using this structure there is further a minimum waste of material. It is of minimum weight because of no duplication of intermediate walls, but by a merging of these intermediate walls to the maxi mum extent practicable into common walls. As these walls merge, they are so configured as to be light, stiff and not exposed to rupture. The extension of the common walls eliminates waste between walls. Accordingly these dies contribute to a very considerable extent to manufacturing utility in their features of up-keep maintained at a minimum and the economies in handling due to their being of minimum weight, and the economies in operation due to their grouping permitting the cutting of a maximum number of blanks with a minimum of waste material.

In the operation of the die by action of the press against the press face 16 to drive the cutting edge 17 directly therebelow through the mutiple thicknesses of fabric, this action occurs on a wooden block 26,

with the dies of the open top type. This open top as to the general die form permits a removal or pounding out of the blank itself for removal from the lower side. Removal from above is not possible with the die blank 6 for the brace 27 carrying the thumb hole cutting portion 8 rigid with the main walls of the die blank 6 bridges a portion of the blank.

hat is claimed and it is desired to secure by Letters Patent is:

1. An integral die form comprising two cutting dies, the forms of both being moditied to form a cutting edge between and common to the two, and having a contour adapted to normal seaming.

2. An integral die form comprising two cutting dies, each in part modified to form a cutting edge common to both, and gradually diverging therefrom, but joining more abruptly than in the normal forms; the dies being thereby rendered less liable to rupture, while imparting to each cut piece a contour adapted to normal seaming.

3. A die form comprising two cutting dies having in part a cutting edge between them common to both; said cutting edge having a contour intermediate of the normal contours of the two dies.

t. An integral die form embodying an open top surrounded by a wall having a press actuated face, said die form comprising two cutting dies, the forms of both being modified to form a cutting edge between and common to the two, the dies being thereby rendered less liable to rupture in simultaneous cutting through a plurality of thickness of material, while imparting to each cut piece a contour adapted to normal use.

5. A die form provided with a cutting edge and spaced therefrom a press actuated face, and, intermediate the cutting edge and face and extending laterally from the die, a hand grip rigid with the die form. and disposed sufliciently below the plane of the press actuated face for freedom for regular grasping with the hand even with the press in the plane of the press actuated face, thereby precluding injury to the hand in operation of the die form.

In testimony whereof I hereunto set my hand in the presence of two witnesses.
