Application October 17, 1947, Serial No. 780,384

This invention is a novel sectional container 1 for holding cutting dies and tags within the container in convenient positions, which dies and tags are needed in the process of cutting shoe upper blanks, or the like, the same increasing the efficiency of handling the dies.

At the present time, a great .deal of time is lost in handling cutting dies due to the fact that the operator usually has several sizes on a job, which sizes are bound to become mixed. The normal operating of cutting shoe and other blanks necessitates the operator going to a die-rack to select the proper dies and bringing them to his machine, piling the dies on the block. Most cutting dies are double-edged and thus the piling of such dies on the block results in damage to one or both cutting edges. When he changes sizes he loses time by having to sort the dies over to obtain the right size. He loses 'more time when putting them back in the rack because he has to sort them again. When the cripple-cutter wants a die for making a, cut, more time is lost in the same manner. Moreover, in cases where has a pattern with several piecesto a pair, considerable block space is required to take care of the dies. More block space is again wasted when he spreadsthe tags out thereon as is customary. Having dies and tags scattered on the block in this manner gives the room a disorderly appearance, and

also creates a certain amount of confusion which can be eliminated or materially reduced by the use of my cutters die-box having sections which my be numbered by the same system now used on the die-racks, making it very simple to shift dies from the racks to the box or vice-versa.

- The principal object of my invention is to provide a cutters die box adapted to be suspended from a cutting machine, the same having means for keeping all of the dies needed by the cutter, in proper order, off but adjacent to the work block, and thus in a convenient position, the dies being free from the hazard of becoming dulled by their cutting edges being rubbed together.

Other objects of my invention are: to provide a sectional container for cutting dies, the use of which will make all table and block space available for actual cutting; will keep the various sizes of dies separated, thereby eliminating one of the main causes of dulling of the dies due to rubbing of the edges together; will speed production, reducing the time required to change dies because the dies are kept in proper order in the container; Will retain the dies in proper order di- 6 Claims. (Cl. 211-86) rectly in front of the operator so thatthe operator can tell at aglance, without stoppingwork, whether he has a particular die needed by anothercutter orby a cripple-cutter; will maintain a more orderly appearance in the cutting room by keeping the tags and dies, not in use, or?

I of the tables and blocks; will reduce materially the number of mistakes especially where one part or parts of a shoe are cut up or down fromthe rest, as the dies can be arranged in the box in the order they are to be used; will provide a flexible pocket in the upper section of the container serving as a oonvenientplace to keep the tags so that they need not be tied'up while they are out of the cutters way; will provide a hanger for the sectional container, constructed in such a manner that it will swing in the event the con-- tainer is hit by a cutting arm, or in event the operator wants to get dies from the containerwithout bothering the cutter; will provide av hanger which can be lifted off the cutting machine "for cleaning, or when the machine is needed for repair or when the block needs planing; also, will provide a sectional container which can be taken to the rack and filled withdies, putting them in the container in order, thus sav ing sorting of the dies at the machine.

I will explain the invention with reference to the accompanying drawings, which illustrate one practical embodiment thereof, to enable others. familiar with the art to adopt and use the same; and will summarize in the claims the novel lea-- I tures of construction and novel'combinations of parts for which protection is desired.

Fig. 6 is a detailed section.

The shoe cutting machine A (Fig. 1) is pro-. vided with a block B, having an upper casting C, provided with a hole (not shown) in one side whereby the tripping device of the machine may be oiled, the hole also serving as a means for 3 suspending the holder on the side of the machine. Usually the upper casing C is substantially cylindrical adjacent the bench B. The construction of the cutting machine, upper casting C, and bench B is well known and forms no part of my present invention.

As shown in Figs. 1, 4 and 5, my sectional container is preferably of rectangular shape, the same being provided with a front I, a back 2, side walls 3, and bottom 5, the container being of substantial depth, and bein provided with handles 4 at the tops of the sides 3 whereby the container may be readily lifted or transferred. A

series of spaced vertical partitions 6 is provided 7 within the container, extending from the bottom 5 to the upper edges of the side walls 3, the same preferably having their ends dadoed into the side walls and bottom of the container. The spaces between the partitions 5 and the front wall I of the container are adapted to hold shoe or other cutting dies, which may be single edged or double edged, the dies being placed in proper order of use therein and the partitions keeping the dies in adjacent rows separated and spaced apart so that their cutting edges will not become dulled by rubbing together. If desired, the walls and partitions of the container may be made of wood,

Masonite, or other thin material having a requisite strength.

Between the rear wall 2 of the container and the adjacent partition 6 is a flat rubber strip 7 (Figs. 4 and 5) normally lying along the inner face of wall 2 and having its ends bent as at l'c toward the partition, the bent ends being clamped in position by means of clips 8, secured by bolts 9 or the like to the sides 3 of the container, as shown in Figs. 4 and 5, the rubber strip I forming a flexible and extensible pocket adapted to hold bunches of tags 'I' used in connection with the respective dies in the process of cutting.

The sectional container is held in position on the cutting machine A beside the uppercasting C, same slanting at a convenient angle upwardly from the front wall I to the rear wall 2. as shown in Fig. 1, by means of a holder" IQ of open rectangular shape, having upwardly extending side flanges Illa slightly larger than the outside measurements of the lower end of the sectional container, whereby the container may be readily lifted into or out of the holder I8, using the handles 4. At the end of holder I0, adjacent the upper casting C is a vertically disposed hanger I 2, having a flange Ila at its upper end, adapted to overlie the top of upper casting C, the flange being provided with a stud I Ib adapted to enter the oil hole in the top of the uppercasting C, as shown in Fig. 2. The holder III is secured in angular position to the hanger II adjacent its mid point by means of screws or" rivets I2 so that the holder will retain its angular position on the machine.

The lower end of hanger II projects below the holder H] and is provided with a flange Ho par-' allel with the flange Ha, i. e.,'extending toward the upper casting C; Upon the flange IIcis a plate I3 having a circular recess I3a in its outer edge adapted to contact the curved side of the upper casting C. Plate I3 is maintained upon the flange He by means of rivets or'screws I4, as shown more particularlyin Fig. 6. In order tomaintain the outer end of the holder I!) in horizontal position, a brace I5 is provided below the holder, having its outer end flanged as at I5a and secured by rivets It or the like to the flange IIIa of the holder ID, the brace I5 sloping inwardly and downwardly to meet the lower 'end of hanger II and having a flange I5b underlying the flange I lo, the same being secured thereto by the rivets I4 which secure the plate I3 to the flange I I0, brace I5 maintaining the holder I0 rigidly supported upon the hanger I I to support the weight of the sectional container carried by the holder. Preferably, the holder I0 is made of angle-iron, although the same may be made of any other desired material and in any other desired manner.

I do not limit my invention to the exact form shown in the drawings, for obviously changes may be made therein within the scope of the claims.
