. A CORPORATION or NEW JERSEY.
METAL-ENDING DIE.
- To all whom it may concern:, r
fiO
Be it known that I, GEORGE A. OHL, Jr., a citizen of the United States, residing at Newark, in the county ofEsseX and State of New Jersey, have invented certainnew and useful Improvements in Metal-Bending Dies; and I do hereby declare, the following to be afull, clear,--and exact description of the invention, suchas willenable others skilled in the art to whichit appertains to make and use the same, reference being had to the accompanying drawings, and to characters-of reference marked thereon, which form a part of this specification.
Thepresent invention hasreference, gensheet-metal; and,'-xthis invention relates,
more particularly, to a novel arrangement and construction of dies adapted to be used in'that class ofpower presses which are employed for bending and forming sheet-metal into desired conformations, such forexample, as bending and forming the sheet metal into various forms of corner-pieces,
angle plates and the like.
The invention has for its princlpal ob ect to provide a novel arrangement and construction of dies by means'of'which may be formed or shaped small nose or bull nose corner-pieces, such as are connected with the angles of plasteredwa'lls'to reinforce the wall plaster at such points, and thereby prevent chipping and breaking of the wall plaster at such corners or angles.
Other objects of the present invention not at this, time more particularly enumerated will be clearly understood from thefollowing detailed description ofthe present 1nvention. l
WVith the objects of the present'invention 'in view, the said invention consists, primarily, in the novel construction of dies hereinafter 'set forth; and, theinvention consists, furthermore, in the novel arrangements and combinations of'the various parts of" the dies, as well as in'the details of the construction thereof, all of which w1ll be hereinafter more fully described, and then finally embodied in the claims which are appended to and which form an essential part "of this specification.
' The invention is clearly illustrated 1n the accompanying drawings, in which Figure 1 is a transverse vertlcal section of Specification of Letters Patent.
and embodying theprinciples of the-present invention, the same being shown in their normal 1n1t 1al posltions; Fig.2 is a similar vlew showing the novel bending dies in their operated positions upon the completion of their bending operations; and Figs. 3, 4: and 5 are respectively cross-sections of small noseand Fig. 6 of bull nose corner- Patented Sept. 22, 11914..

pieces of the character possible to be formed 7 by the ope-ration of said novelbending dies.
1 Similar characters of reference are employed in all of the above described views, to
indicate corresponding parts.
Referring now to said Figs. 1 and 2 of the drawings, the reference character 1 indicates theI-bolster or main-body of the upper die-member from the upper surface of which pro ect the pairs oflugs or ears 2 adapted to embrace the hammer of a power press for operating said dies, and which are detachably secured to saidhammer by means of the transverse dowel-pins 3. Said bolster or main-body 1 of the upper die member corresponds inlength to the length of cornerpieces desired to be formed, such length being usuallyin sizes from eight to twelve feet, although of coursethe invention is not to be limited in this respect. Formed in the under side of said bolster or main-body 1 are a pair of longitudinally extending channels or grooves 4, in which are received the longitudinally extending stocks or tailpieces 5 of cam-members6 which are secured to the under side of said'bolster or main-body 1 by means of bolts or screws 7 The said. cam-members 6 parallel each other,
and are maintained by, the engagement of their stocks or tail-pieces '5 with said channels or grooves4 from any lateral movement of displacement with relation to said bolster or main-body 1. Each cam-member 6 is provided with a properly inclined cam-surface 8, and adjacent to the inner marginal edge portion of each cam-member 6 is a flattened hammer+portion 9. Connected with said bolster or main-body 1 so as toextend longitudinally between said pair of cammembers 6 is a plunger die-member 10, the lower or free end of which is wedge-shaped to provide a male die-portion, 11, having upwardly diverging side. surfaces 12 which may be curved to any desired degree, or which maybe flat surfaces, or which may be a combination of curved and flat surface 55 the novel bending dies madeaccording to according to the desired form to be given to the flaring walls of the corner-piece to be bent or shaped. -Saiol plunger-die member 10 is so associated with said bolsteror main body 1 as to be capable of a yieldable vertical movement with relation thereto, and to accomplish this end there are provided openings or sockets 13 extending vertically through said bolster or main-body 1,:-andk formed within said openings or sockets 13 is an annular shoulder 14L which provides a restricted opening 15 of reduced diameten.
die-member is yieldablycmaintained in its projected position by springsl8r surround: ing saidbolts 16 between the upper, surface i ;of said plunger die-member 10 and. said shoulders 14, so thatthe same are arranged within the lower. ends of said openingsor sockets, 13.. on
The reference character 19 indicates the bed plate of the lowerdie-member, the same benig'provide'duupon its, under side with a longitudinally extendingcrib 20. adapted to be received in a corresponding groove in-the anvil of a POWGI'rPI'QSS to thus aflix said lower 1 :die-member to the'latter, and in proper registration with, the upper die-member as carried, by the hammer of said power-press. The uppersurface of said bed-plate 19 is provided with a longitudinally extending TBchannelQ-l corresponding in width to the 40 Width ofsaid cam-members 6 as attached to the bolster or main-body l of said upperdiemember, and which are adapted to enter said channel '21 whenysa'id upper die-member is carried into cooperative relation with said.

adapted tocreceive the'operat'ive engagement of the cam-surfacesS of said, cam-members 6 of the upper die-member. The said, upper surfaces of said oscillatabledie-members 24 are also provided with longitudinally ex-v tending receiving-surfaces 27 adapted to receive the contact and pressure of said hammer-portion 9 of said die-members 6 connected. with said. upper die-members Ins serted in the oppositely facing inner edges of said oscillatable die-members 24 are longitudinally' extending pinching dies 28, the 7 -same having downwardly projected die-portions 29, the' rear or under sides ofwhich are (undercut. as at.30. Said pinching-dies 28 are made, preferably, vof hardened tool steel. Extending centrally, and longitudinally through said channel 21', the same being seatedz in a groove 31 whereby it is retained against-- lateral displacement, is a female-die 32,havin g,a;conc aYe:die;por-- o tion 33in :its upper, surface. Said female; 30 die 32 is alsof preferably madeof hardened; tool-steel In order to returnandmaintain said oscillatable die-members 24: in their.no ry mal initial or raised positions there are .pro-
vided; compression springs 34: which are seated in receiving recesses orj sockets, 35 7 formed in the bed-platelt), the uppenends of said springsfil beingseated in depressions. cr -sockets 86 formed on theunderside of said oscillatable die-members. 2t.
