I SECTIONAL DIE.

Specification of Letters Patent.

Application and April 14, 19o9.fl Serial No. 489,544.

respectively, of Dorchester and Roxbury both in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sectional Dies,

of which the following is a specification.

This invention relates to cutting dies and particularly to that class of dies which are utilized for the purpose of cutting blanks for use in the manufacture of bootsfan shoes.

It has for its object the provision of a die having a knife blade of irregular form for cutting out the outline of the blank and provided with stiffening webs formed in-.

tegral therewith interposed between the two portions of said knife blade for the purpose of stifiening the same andretaining the outline of said die.

It has for a further object the provision of a meansfor securing to said stiffening webs a second or smaller'die within the confines of the knife blade of the larger die.

.Another object of the invention is to provide the intermediate members Within the confines of the knife blade with a pluralit of punches adapted to ornament the blan: while it is being cut from a piece of material.

A further objectof the invention is the provision of a plurality of marking or spacing pins adapted during the cutting-of the blank to prick the blank for the pur ose of showing the exact position of lap o the other parts of the upper stock tobe sewed thereto in the construction of the boot and shoe or for the purpose of centering the blank upon the last during such construction.

It has for a further obj ect the production of a yieldable markin member adapted to indent the blank, whi e being put from a piece of material, to form in the blank a line to serve as a guide for the stitcher durin tlfie t e blankis used.

It has for a further object the adjustability of said marking member relative to the cutting blade of said die.

- The invention consists certain novel .features of construction and arrangement of partswhich be readily understood by reference to the description of the drawings and to the claims herelnafter given.

0f the drawings: Figure 1 represents an inverted plan of a die embodying the features of this invention. Fig. 2 represents an elevation of the same. Flg. 3 represents a section of the same, the cutting plane being on line 3-3 on Fig. 1. Fig. 4 represents an elevation of one of the marking or spacing pins. Fig. 5 re resents a detailed sectlon through the stiffening webs and the smaller die secured thereto, the cutting plane portion of one of the smaller dies and showmg the punch mounted therein. Fig. 7 represents a section-through the'die,the cuttin plane being on line -7 on F1 1, an showing in elevation the adjustab e marker supporting member mounted therein. F 8 represents a sectional detail through the same, the cutting plane being on line 8--8 on Fig. 7. Fig. 9 represents a sectional detail through the same, the cutting plane being on line 9-9 on Fig. 7. Fig. 10 represents a plan of one of the springs interposed between the marking member and its supporting member, and Fig. 11 represents a sectional detail, the cutting plane being on line l111 on Fig. 1, and showing the mechanism for adjusting the movable member relative to the cutting edge of the die.

Similar characters designate like arts throughout theseveral figures of the raw mgs.

In the drawin s, 10 represents a continu ous cutting bla e of a die adapted to out blanks for use in the manufacture of boots and shoes, thi cutting blade being provided with a pluraity of stiflening webs 11 interposed between two vparts of said knife blade. The stiflenin-g webs 11 are of less depth than, the knife blades 10 so that when in use the webs never contact with the material from which the blanks are out. These stiffening webs 11 are castor otherwise formed integral with the knife blade 10 and serve to retain the shape of the die and prevent itsdistortion while subjected to pressure in the process of cutting.

The stiffening webs ll ma be 'rov ded atodifierent points therein wit er oratrons 12 in each ofwhich is mounte a marking or :s acing pin 13 which-are adapted, when the lank is being out, to enter the surface Patented Apr. 19, 1910.

being on line 5-5 on Fig. 1. Fig. 6 represents an enlarged sectional detail through aof the material at a stated distance from the edge of the blank and make suitable indentations therein which will serve as a uide to show the exact position of lap of t e other parts of the upper which are to be stitched thereto in the process of constructing the boot or shoe. The point of the marking or spacing pin 13 is sh htly within the plane of the knife edges of t e blade 10.

Formed integral with the cutting blade 10 and with the stiffening webs 11 are other.

intermediate members 15 which project toward each other leaving aspace between adj acent faces thereof in which may be mounted a second smaller die 16. This die 16 is is being died out. This die 16 is also provided with a plurality of ornamental cut:

ting members 19 threaded, thereto as indicated in Fi 5 and 6,-these cutting members being a apted either to cut out from the blank small portions thereof in any desired shape or simply cut into the surface of the blank to leave an impression. therein and give an ornamental appearance to that portion of the blank. In some classes of shoes it is very desirable to ornament the blank in the manner described but in a cheaper grade of shoes this ornamentation is omitted, .1n which case the pins or locking members 17 may be removed and the die 16 withdrawn from the die 10 and plain blanks cut therefrom in an obvious manner.

Extending from one of the stifi'ening webs 11* to ears 20 and freely revoluble in bearings therein are two threaded members 21 extending through a member 22 provided with threads engaging the threads of said revoluble members 21, It is obvious that by turning the members 21 the member 22 may be adjusted toward and from one portion of the knife blade 10.

In vertical openings through the member I nterposed between the member 22 and the members 24 are a plurality of flat springs 26 provided with notches 27 at their ends,

into which the upper edge of the blade 24 extends. Each spring 26 also has a central opening 28 which surrounds the reduced end 29 'of an adjusting screw 30 mounted in the member 22 and adjustable to regulate the tension of the springs 26. Interposed between this adjusting screw 30 and the blade 24 is also a spiral s ring 31, the tension of which is likewise a justed by turning said screw 30. When the tension of the springs has been properly adjusted the screw 30 is prevented from turning by means of the check member 32 threaded to said member 22.

This provides a very convenient form of die cast or otherwise formed in one piece with a continuous cutting knife blade stiffened by means of suitable webs formed integral therewith, these webs providing means for securing thereto in any convenient location marking or other spacing members adapted to serve as guides for the lap of other portions of the upper to bestitched thereto or to receive cutting members which are adapted to cut into the face of the material or through the material a plurality of ornamental designs or imitation stitches. It provides a means of utilizing the same die for cutting plain blanks or for simultaneously cutting the blanks and cutting or impressin therein ornamental designs while it provides a means of detaching the second ornamentin die and substituting therefor other secon ary dies of any desired form to vary the design to be impressed into'the blank. It also provides a ready means of marking into the surface of theblank, at the same time that the blank is being cut, a line of indentation which may serve either for ornamenting the blanks or as a guide for the stitcher in the construction of the boot or shoe for which the blank is used and it provides a means for adjusting the position of this marking member relative to a portion of the cutting blade and also a means for permitting the marking member to yield under pressure.

It is believed that from the foregoing description the operation and many a vantages of the invention will be thoroughly understood.

Having thus described our invention, we claim: r v
