DIE SET HANDLING FLANGE AND COACTING HOOK Filed Sept. 2, 1948 2 Sheets-Sheet 2 INVENT'OR lfivsmme- JAN s zewsx/ Patented Aug. 4, 1953 UNITED STATE PATENT OFFICE Kasimir J aniszewski. Milwaukee, Wis., assignor to Superior Steel Products Corp., Milwaukee, Wis., a corporation of Wisconsin Application September 2, 1948, Serial No. 47,353

This invention relates to improvements in die set handling flanges and co-acting hooks.

, It is a primary object of the invention to provide one or both plates of .a die set with novel flange means which not only enable a hold down clamp to operate effectively on the die shoe but also facilitates both manual handling and the application of either conventional or novel hoisting means for positioning the die'set or moving it respecting the bed of a press in which such set is used.

More specifically stated it is a purpose of the invention to provide one or both plates of a die set with laterally projecting horizontal flanges, each plate preferably being provided with cooperating vertical surfaces for protecting the operators fingers and for positioning a hoist and a hold down clamp. From the standpoint of one species of my invention it is a purpose to provide more than one horizontal flange. From the H standpoint of another species of my invention it is my purpose to provide a convoluted marginal flange and a special co-acting clip which may be connected with a hoist and is formed for engagement and disengagement with such flange to facilitate manipulation of the die set.

It is a further object of the invention to provide a novel clip for the purposes aforesaid. Other objects will be apparent from the following detailed disclosureof my invention.

Figure 11 is aview in perspective fragmentarily illustrating another way in which the detachable clip can be releasably anchored tothe manipulating flange of the plate.

Referring firstto the construction shown in Fig. 1 and Fig. 2, I have illustrated at IS a die shoe provided with the usual leader pins at I 6 for guiding the punch holder. Each of the leader pins is conventionally mounted in a projecting ear portion ll of the shoe. In accordance with the present invention, a handling flange is welded at l8 to the side of the shoe and preferably also welded to the ear at H, the location of the flange being preferably about midway of thethickness or height of the sh0e.,

Integrally welded to the shoe and to the flange I8 is a channelled or U-shaped member. 19 which provides vertical flanges at 20 and 2| and a horizontal flange at 22. The hold-down finger 23 extends into the U-shaped member l9 and is engaged with the bottom flange 22 thereof under compression of the clamp screw 24 which connects the hold-down to the bed of the press. ;The finger 23 may be, and desirably is, supported at its outer end by a heavy shim 25 which leaves the finger approximately horizontal. The vertical flanges 20 and 2| respectively welded to the under surface of the horizontal flange I 8 serve to confine the hold-down finger against lateral displacement, thereby making it perfectly secure when in use.

I preferably provide a further verti calflange at 26 welded to the shoe and to the under surface of flange I8 and'spaced from the flange 20 at approximately the same spacing as flange 2| so that the three flanges are approximately uni- .formly spaced at the side of the shoe. This er:-

rangement facilitates the'application of a special hoisting clip such as that shown in Fig. 9 and later to be described. However, the horizontal flange I8 is also desirably provided opposite its center of gravity with an aperture at 28 into which a conventional hoisting hook such as that shown at 29 in Fig. 3 is readily engaged for lifting the shoe ifo r itsmanipulatien its and prom the press. The structure described and shown on the right hand side of the shoe in Fig. 2 is desirably duplicated at the left hand side of the shoe as indicated in Fig. l. V

In Fig. 3 the shoe differs 'in shape, "being long and narrow. The leader pins [6 may be identical with those above described but are l'e'cated at the remote ends of the elongated shoe 'llill. "The laterally projecting flanges I80 are similar to the flange I8 already described :but are longer, desirably extending substantially the entire length of the shoe I50. Since they areloirger they are provided with a number of the U-shaped members l=9 instead Wf with 3a single Oil'e thereof as the device shown rim Figures 1 and '2. hviously the hold-down fingers 23 may be applied in an? '0'1 mere "CT the shaped members l9. Any desired number e'f apertures be provided in the flanges it!) to receive the Fhoist neck or trucks as.

For hoisting purposes the work of iabricating the hoisting flamges may be materially reduced by adopting one or another of the constructions shown on sheet '2 of the drawings. In the construction shown Fig. -1l,=eaeh of the flanges it: applied 'to the slide 1 and the punch holder 3'6 has one planiferm surface l t-2 and one teenvol-uteil surface W3. A pair or the special flan'ges shoixm inrig. 4 may readily be made with *econ only or material the manner indicated in Fig. by using a torch to make a com eluted 'cut at 81 through 'a piece er bar stock to form the two members WI, the outer tapes er the ha-r stock forming the planiiorm-surfaces 1'82 and the pat-h of the torch forming the corrvdluted surfaces 1*"83. Two nahge devices may thus be made from a bar only one tou-i th inch tlli'dker than "would be required 'tor one. The resultant effect is to produce one piece -a flange comparable to the flange it *of Fig. =1 rrom which there are depending flanges in the form of uniformly spaced teeth. The product is welded to the side of the plate Pi l or 3D the same manner as the fabricated assembly is welded to the side cf the plate It in '-1 a l-1d Fig'.

A somewhat similar *device "may be made as suggested in Fig. 5 by simply convoluting 'apiece of strap iron in the manner indicated at 184 and welding i-t to the side "or "the-plate T53.

' With-my improved type of flange I preferably employ animprovedhoisting clip which may have the construction shown in Fig. 9 or that shown in'Fig; llyortliaitshowh'inl igpfi andFi'g. '7. In either case the li comprises a plate portion 32 or 338.! which comprises the top 'of an open channlfthe bottom of the channel comprising a pair of spaced fin'gersat 3'3. Across the back webportion "33-01? the channel is welded integrally a ring at 3'5. 1 may provided the top flange "32 and the respective fingers t3 with registering apertures 36, 3! (Figs. '6 and '7 in which case '1 may "also provide similarly spaced apertures at 38 (Fig. 4) in'th'e lateral flange provided on the shoe and on the .punch holder respectively. The apertures in question are not essential but where used they accommodate locking pins 40 which pass downwardly through the clip and through the flange on the die plate, thereby releasably locking the ill) . plished .is shown in Figure 11.

4 clip to the die plate and making it possible to connect the hoisting hook 290 to the ring 35 without any possibility of the clip becoming disengaged from the plate. The connection is particularly useful when a hoist is connected with one clip only, as in turning a die plate over. In ford-many vertical-lifting, the use of the locking pins '40 is not at all essential as the tension of the hoist chains is exerted in a direction to hold the clip to the flange. However, for special manipulative .punposesias last described, it may be desirable to lock the clip to the plate by means of a pin 40 or otherwise so that it cannot become -'dieen'gaged the tension is outwardly rather than inwardly.

"Another way in which this can be accom- The clip may be identical with either of those already described. As shown, it is the same as that shown in Fig. 9 with the exception that it has a channel 32! out in its wider surface. For cooperation therewith the flange its provided on the his set plate has a complementary chamnel at 1789, each or the channels 321 and 189 being sem' rcylinrlr loal and adapted to receive the key mm which is detacha'bly slid therein to anchor the clip to the iiiange. For marilpuiaiticn of the hey, may be provided with an upstanding handle at GM. A device so constructed sufficiently strung so that it will handle a time lp'ound plate wan ease and yet the clip may be instantly applied or released by simply inserting or withdrawing the key mm.

Instead of having the ring 35 "integral "the clip as shown in Fig. 9, "I provide the clip with ears H, W: spanned by a pm tle at '13 plyotally supperting the ring '35!) so that the ring is ssh-adjusting in position when engaged by the hook in the manner indicated Figures 6 and 7.

While all or the various die shoes and punch holders thus falr described here has the respective handling flanges located midway of their sides, Fig. 8:shows how the heavy sh'oe I-55'm'ay have the handling flanges 1 and Hi6 located adfia'c'ent its forward eater corners and the barn dling flange w! located midway or its back. Using three olthe el ips as shown in Fig. 9, each connected with one of the cha'iin's 45, 46 and '41 of ='a suitable ho'ist, it is readily possible to manipulate even the heaviest plate. What is more, the locations of the several clip flanges in the specific 'ioeations indicated, facilitate manipulation oI a heavy shoe its turn it upside down or from side to s' ide or to any desired position. It will he apparent that it the hook '4'? is disengaged from the flange it?! at the rear of the shoe, for example, all of the lifting i orce of the hoist will he applied to the front corners cf the shoe and "it will readily :be possible to tum the shoe up for manipulation or, if desired, to turn it over.

In no case can the clip slip long-ltudmally of one or the flanges with which iit is engaged, since the downwardly protecting teeth :or vertical flange "portions of the eohyolutetl lower surface are engaged by the fingers 33 to preventcsmy such dis lacement. While the iclip as slmwn is part'icu larly devised for engaging the convoluted flanges shown in Figures 4 to lo, it will ee :aparent that the "identical "clip, with or without modification as to form, may-alsob'e'use'd toprovi'de a secure gri on the type of flange shown in Fig. 'zor'that shovm'in Fig.3.

Whena complete die set, such asfthat'of Fig. 4, is'to'b'e handled as a unites in Fig. "6 and Fig. 7.

the flange l8! applied to the punch carrier plate 30 is desirably, inverted, withqits; convolutions or teeth uppermost. Thenwhen the hoist hook 290 is engagedwith a clip. attached to the shoe l5l, the chain 44 attached to the hook will enter betweenthe convolutions I83 of the flange on the punch carrier and the interlock thus elfected will hold the entire set upright. (Figs. 6 and'l.)

Assuming that the plates of the die set arenot too heavy to be lifted manually, it. will also be apparent that th channels between the downwardly projecting teeth, or the pockets provided by the vertical flanges of the device of Figures2 and 3 areadmirably adapted to receive the operators fingers and to secure the operators hands against slipping respecting the plate, and also to protect the fingers from possible damage through contactwith the underlying bed of a press; Thus, whether the die set is manipulated by hand or by power, it can be handled more securely and more positively and more easily through the use of the means, embodying this invention, th flange being in every instance located intermediate the top and bottom of the plate to which it is marginally applied and the vertical flanges orfingers preferablyv extending vertically from the horizontal portion of the flange and providing recesses for the fingers.
