.To all whom it may concern.-

Be it known that I, HOWARD T. HALLO- WELL, a citizen of the United States, residing coact with one or more. dies to produce a plurality of successive operations upon a blank.

of metal or the like.

It further consists of meansfor shifting the blank-holding die from the path of one of the cooperating dies to that of the other for successive engagementtherewith.

It further consists in providing dieblocks the adjacent faces of which are inclined at an angle with the horizontal. f

' It further consists of means for supporting and securing the dies in said blocks.

It further consists of novel fea'tures of construction, all as will be hereinafter fully set forth.

Figure 1 represents, chiefly in vertical section, drawing or stamping press blocks and dies embodying my invention. Figs. 2 and 3 represent sections on the line a: Fig. l1, showing the device in vdifferent positions. Figs. 4 and 5 represent the coactin r ortions of the dies shown in Fig. 1 detache om the device. Figs. 6 and r7 represent in transverse sections the blank at two stages of the operation thereon. Fig. 8 represents a perspective view of a portion of the foot or end die 34. Fig. 9 represents a perspective view of a portion of the end of the upper die 5. Fig. 10 represents a perspective view of a portion of the end of the upper die 6. Fig. 1 1 represents a perspective view of a blank after l Fig. 12 represents a perspective view of a blank after the second forming operation. Fig. 13 represents a perspective view of one of the upper die-sections.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 and 2 designate, respectively, the upper and lower diebeds of a drawing or stamping ress. As the means for reciprocating one o such beds toward the other is well known in the metalworking. art and forms no part of my present invention, I have not deemed it illustrate the same.

Bolted onto the beds 1 and 2 are dieblocks 3 and 4, respectively. In the block 3 are sup orted two dies 5 and 6 with their longitu inal axes in parallel relation. Similarly supported in the block 4 is a die 7. As' shown, the die 5 Ihas a'single downward projection 8, adapted to pass into a recess 9 in the die 7. The die-6 has a downward projection 10 corresponding in shape and posif tion with the projection 8 and has at each side thereof additional downward projecting portions 11 and 12, adapted `to pass outside 3f tme upwardly-projecting portion of the As clearly shown in Figs. 2 and 3, the dieblocks 3 and 4 have their adjacent faces inclined at an angle with the horizontal and are provided with gages 15 and 16 on the bloc s 3 and 4, respectively. As shown, the gage 15 is pivoted at 17 to the block 3, so as not to prevent the movement of the blocks toward each other.

As shown in Fig. 1 of the drawin s, the face of the lower die-bed '2 is consi erably larger than the lower face of the die-block 4 supportedthereon. Guides 18, 19, 'and 2() re provided, enga `ng invrecesses 21, 22, and 23 in the block 4 or guiding the block 4 in lateral movement across the face of the bed 2. As shown, the block 4 is moved on the bed 2 by mechanism comprising a cylinder 24, piston 25, and rod 26. The cylinder is' provided with suitable connections 27 for the admission to both ends thereof of an eX ansive fluid, as steam or compressed air, or of) h draulic pressure. Proper loutlets for the fluid (not shown) are of course provided.

I have described the faces ofthe die-blocks upper block 3 has at its rear end the shoulder 29, against which the rear end of the die 6 abuts. A similar shoulder 30 is provided on the lower block 4, against which the forward end of the die 7 abuts. The shoulders 29 and, 30 act to take the longitudinal thrust of the dies on the faces of the blocks 3 and 4, res ectively.- As shown in Fig. 1, the dieb ocks 5 and 6 are provided at their rear faces with flanges 31, adapted to engage with the upper sides of the shoulders 32 on the dieblock 3, a key 33 (shown in Figs. 2 and 3 of the drawings) securing the die in place. I have shown the lower die 7 as comprised of four HOWARD T.` HALLOWELL, OF HALLOWELL, PENNSYLVANIA.

It will thus be seenthat a relatively small number of blocks or sections may be united to form several different dies of vary- -f ig' atterns and sizes. I have shown. the

Fig. 13' I have shown one form of a blank after theV first-forming operation has been com leted by the coaction of the .dies and 7. n Fig. l14 I have clearly shown the liange dies 6 and 7 have operated thereon. l

The 'operation is as follows: As shown in Figs. 1 and 2 of the drawings, a blank 28 is 1 laidupon theace of the die 7 and held against lateralmotion by the dgage 15 arlild I to ring t e 16. The press is then operate diestoward each other,' as shown in Fi s. 3 The eiectof thls o eration is to produce in the blank 28 the nb or depression 29, (shown in Fig. 6 of the drawings,)leavinglaterally-extending flanges 30 31 at each side of said rib. By means of the three-way cock 32 steam or other fluid is admitted to the left end of the cylinder, as shown in 1, whereby the block 4, die 7,

and artially-.com leted blank 28 are'moved to t e right .of t e drawing Fig. 1, and so that .the dies 6 and 7 are in vertical 'alinement. The dies are then brought together as shown inFig. 5 of the drawings, the pro.-

' jection 10 of the die 6 entering into the rib 2.9.01 the blank 28, while the projecting ribs 11 and 12 cooperate with the ribs 13 and 14 on the 7 to depress the .outer edges of the flanges v30 31 to form de ending flanges 33 34, as shown in Fig. 7 of the drawings. At the same time the elect of the second drawing o ration is to nk 28.

34 to 37, forming the lower die 7, as i 1nclined faces ofvthe block 4. It is evident, however, that any' positive means for securing the blocks together maybe used .as desired and that a similar sectional block, the properly secured together, maybe used 1n the case of the upper dies 5 are readily detachable therefrom. In Fig. 3 of the drawings I have shown the 2.

5 liiioken liange 31, the block 3 having a similar dentatedy shoulder 40. In this construction iron out the wrinkles in the 'sive 'operationsthereon may yary within wide limits. An essential feature of my vdevice isthe shiftingv ofone of the air of coacting dies withthe partly-forine'd lank sup-` portedrrthereon-to engage with another die or other dies, 's whereby. further-"drawing .or stamping operations-'are blank. Y

Another es -c1 vanta eous feature of my device lsth' an. dies secured' therein at .an angle with the horizontal, This is especially advantageous inthe production of articles one end ofwhich is bent at .a greater .angle thanthe other or at any considerable angle' with the ibod of the blank.

A third advantage is in tlie method of securing the dies in the blocks by which they- It is evident that various changes may be made by those skilled in .the art which may come within the scope of my invention,- and I donot, therefore, desire to be in every instance .to the exact constructlon herein shown and described.

Having thus described Amy invention, .what I claim as new, and .desire to secure by Let ters Patent, .ise-
