lIhe completed glove is constructed oftliree pieces, namely, a back section A, a front sec- YtionB and a combined thumb and wrist strip G. The glovemay be formed of knitted orV yrection fromthe main body portion, a'wrist .portion lflxextending in the opposite direction from the main body portion'and a thumb portion l5 so formed that it lies Within'the lateral confines of the blank across the finger' portions thus-causing the 'linger portions to nconstitute the maximum width of the blank.

The wrist portionlt is somewhat narrower than the wrist portion 9 jof the back section WA', and the thumb .portion 15 is disposed in.`

longitudinal alignment with the index iinger Y vportion 13 `and is arranged alogthe respective sidefo-f the wristrportion-l't as is clearly Y shown `in Figurer'of v`the drawing." l In completing the glove, I employ a vcombined thumb and wrist strip C, which'comprises a thumb portion 'lfand a wrist portion 17 which are arranged in alignment, the

Vthumb portion being wider than`the vWrist portion.V Seev full lines in Figure anddotted lines in Figure '5 ofthe drawings. Itis to n be-understood that this combined thumb and Vwrist strip C is to becut by a separate die, the gang die disclosed in this application being adapted for the cutting ofthree setsof defining edge 29.

blanks such as are shown in full lines in Figures 4 and 5.

In my improved die, I employ three sets of back and palm cutting die units arranged in alternated close relation, the rear face dies being designated D and the palm face dies being designated E.

The units are arranged as illustrated in Figure 1 of the drawings and are secured upon the base 18 by having their webs 19 secured to the base in any approved manner. See Figures 1, 2 and 3.

. Each section D includes finger cutting flanges or knife edges 2O including the necessary intermediate edges for separating the lingers throughout their length and delined at one side by the little finger defining edge 21 and at the other side by the index fin er Vdefining edge 22. The unit also inclu es wrist portion base and sides cutting edges 23 and 2a, respectively, one of the side edges being connected by a side cutting and defining edge 25 with the little finger edge 21, and the other side edge being connected by the side cutting and defining edge 26 with the index linger edge 22.

The units D thus constructed are alternately juxtaposed as shown at the left of Figure 1 of the drawing whereby one side cutting and defining edge 25 is common to two units and one side cutting and defining edge 261s common to two units thus avoiding intervening spaces and the cutting of any waste material between the units.

Each unit E includes linger cutting edges 27 for forming the linger portion of the palm blanks which portion is defined at one side by the little linger cutting and delining-` edge 28 and at its other side by the index linger cutting and defining edge 29. These units also include wrist portion base and sides cutting edges 30 and 31, respectively, one of which side edges is connected by a side cutting` and defining edge 32 with the little linger edge 28 the other of which side edges is extended a considerable distance into the main body portion of the palm blanks as at 33.

The extension 33 serves to divide from the palm body portion a thumb extension which is thereby disposed.substantially as an extension of the index finger and which is completed by the thumb Vcutting and defining edges 34 and 35, the former being curved to shape the end of the thumb and the latter being extended to connect with and form an extension of the index linger cutting and It will be observed that the thumb portion formed by the edges 33, 34 and 35 is extended in a direction opposite the direction of projection of the lingers and lies wholly within the lateral confines of the palm blank so that its maximum width is across the position of the lingers. Thus the palm blank B matches the back blank A, except for the slight omission evident at the lower left hand corner of Figure 5.

Ejectors 36 are provided, one being disposed in each die unit Wrist portion, said ej ectors being mounted upon leaf springs 37 which are secured as at 38 with the base 18. The ejectors serve the purpose of ejecting the blanks which have been cut by the die units when the die is removed from the work.

The die is also equipped with laterally extended severing edges 39 which serve to divide the material from which the blanks are cut into upper and lower portions, thereby facilitating removal of the cut blanks and also the saving of the remaining material for future use.

In the foregoing description, I have disclosed a die capable of eliiciently cutting glove blanks in a manner that will insure the manufacture of gloves from a minimum of material and with a minimum of waste. The die units are so constructed and arranged that no cut-outs or waste materials are severed between the blanks, the adjacent edges of the respective blanks serving as common cutting edges. The employment of a die having a reversely directed thumb cutting equipment makes it possible to form palm blanks which provide the necessary thumb portion and yet are no wider and thereby consume no more space than the back blanks.

From theforegoing description taken in connection with the accompanying drawings, it is thought that the novel details of construction, the manner of use and the advantages of my'invention will be. readily apparent to those skilled in the art to which it relates.

I` claim as my invention:
