Specification of Letters Patent.
Patented Dec. 1, 1908.
Application filed September 19,1907. Serial No. 893,606.
To all whom it may concern:
citizen of the United States, residing at New- York city, in the borough of Brooklyn and State of New York, haveinvented certain new and useful Improvements in Dies, of which the following 1s a full, clear, and exact description. I
My invention has for its obj ect the production of an improved die for the bending of sheet metal and more particularly for the forming of a flange upon the extremity of a tubular blank, such as may be used to form the body of a can or receptacle, and my invention consists of the features which will be hereinafter set forth and claimed.
Reference is hereby made to the accompanying drawing, of which Figure}, is a side elevation of a die press to which a pair of dies constructed in' accordance with my invention are applied, and showing a blank in osition for being operated upon. Fi tion of the same; i 3. is a lan of the improved die with a b ank held t erein; Fl 4. is a side elevation of the same, the blan being partly brokenaway; Fig. 5. is a section on line 5 5 of Fig. 3, showing the blank in position before it has been operated u on; Fig; 6. is a similar view showing the b ank after it has been 0 erated upon, and Fig. 7. is a side elevation o the finished blank.
Corresponding parts in the several views are designated by the same reference numerals.
The die press 1 may be of any usual and approved form, and is provided with a vertically adjustable bed 2 for holding the lower die 3 and a vertically movable plunger "4 which acts upon the u per die 3, the blank'o being held between tie two dies.- Each of the dies 3 comprises a body 5 in the form of a having a central raised portion 6, and a surface extending laterally therefrom. The margin of the raised portion forms a continuous or annular guide or shoulder 7, curved in the direction of movement of the material forming'the blank a. Secured to the body 5 by horizontal hinges S are a number of lates 9, preferably fonnwhen the blankto e operated uponis of the form shown, that is, a
I square with rounded corners. These plates are normally held in the positions shown in Figs. 5 and 6, by springs 10. When in this position their inner edges form a continuous guide adjacent to and cooperating with the 2. 1s a front eleva-.
guide 7, and said inner'edges as shown at 11 are rounded or curved in the direction of movement of the material forming the blank a. It will, therefore, be obvious that as the blank a is pressed down toward the body 5 of the die, its lower ed e will be .bent by the co- 0 eration of the gui es 7 and 11 into the form s own in Fig. 6 so as to form a flange b, Fig. 7 around the lower edge of the blank a, and when an upper die is used a similar flange will be formed around the upper ed e of the said blank. After this operation as been effected, the blank a may be readily removed from the die 3 as the plates 9 turn upon their hin es 8 to the osition shown in dotted lines in ig. 4, there y permitting the flange b to clear the edges of the said plates, the said flange being also indicated in dotted lines in 4. aving now described my invention, what I claim, is:
1. A die comprising a body having a raised guide, a surface extendlng laterally from'the guide, and a plurality of hinged plates opposed to and cooperating with the guide and laterally extending surface to ange a blank forced therebetween.
2. A die comprising a bod having a raised guide, a surface extending laterally from the guide, and a plurality of horizontally hinged plates opposed to and cooperating with the guide and laterally extending surface to flange a blank forced therebetween.
3. A die comprising a body .having a raised guide, a surface extending laterally from the guide, and a plurality of spring from the guide, and a plurality of hinged plates opposed to and cooperating with the guide am laterally extending surface, the
edges of said plates forming a continuous said plates being 'llu guide to'fienge a blank forced between the eeme and the said raised guide.
6. A die comprising a body having a raised guidein the form of a square with rounded corners,'e surface extending laterally from the guide, four plates carried on horizontal hinges and having edges forming av square with rounded corners, and cooperating with the guide and laterally extending surface to flange a blank forced therebetween.
Z. A die eoniprising a centering guide and e laterally extending surface, and a hinged her cobperating k. forced therebetwen.
A die comprising a, guide in the'fo'rm of therewith to flange :1 5
an outwardly facin abutment and a, laterally extendin sur ace and a hinged outwardly yieldahle member 006 erating therewith to flange a blank forced t erebetween.
9. A die comprising a guide in the form of i an outwardly facing abutment and a later- 1 ally extending surface continuous therewith, and a-hinged outwardly yieldeble member cooperating therewith to flange a blank forced therebetw'een.
In Witness whereof, I subscribe my signw ture, in the presence of two Witnesses.
