blanks by hand for future operations. Obviously a device which'willstack the blanks at the time that they are formed will produce a considerable saving in obviating the hand stacking. r

The object of this invention is to provide a simple and inexpensive device for stacking blanks at the time that they are formed.

In accordance with the general features of V the invention there is provided a chute which =7 abuts against the die of a, punch press and conducts blanks punched therethrough away in an orderly fashion into engagement with stacking rods for stringing the blanks. The

7 cross section of the chute conforms substantially to that of the blanks in order to align the blanks in a stacked formation, and means are connected to the chute for preserving this,

' Springs 28. are attached to, the end .of the order. r A clear understanding of the invention will be had from the following description of one specific embodiment thereof when taken in connection with the accompanying drawing, wherein V Fig. 1 is an elevational view of the apparatus as used with-a punch press: I

Fig 2 is a sectional view of the apparatus taken on line 22 of Fig. 1;

Fig. 3 is detail view ofthestacking rods; Fig. 4 is a view showing how the stacking rods are used after they are filled, and

Fig. 5 is a detail view of a retarding block. Referring now to the drawing in which like numerals designate similar parts throughout the several views, there is dis closed an ordinary punch press which is one of a number of part or blank forming machines with which the improved magazinmg structure may be used. The press 15 possesses the familiar essential components of a punch press, consisting of a punch 16,

to a: cr0ssbar36 within a counter 17 for supporting a sheet of stock 18, and adie 19 having an aperture 20 through which the 'punch forces a portion of the stock 18. to form blanks therefrom.-

The improvedi magazining' or stacking structure comprises achute 22 which is con nected by brackets .23 and screws 24 to the bottom of the die 19. This chute "provides an inner. passageway orjguide'way '25 which conforms in cross sectionto the outline of emeo wns'rERN" ELECTRIC thedie aperture 20 and thebrackets 23 positionthe chute 22 s01'that-- the passageway25 cooperateswith the die aperture 20 and receives the punched'blanks, in the same position' in which they are? blanked, withoutallowing them to'be turnedaround or about themselves. Thus, it'is to be understood-that V the passageway 25 is designed to conduct the successively punched blanks away from the die 19 in an orderly fashion and to align them fully below. a i

in a "stacked formation, as will appear more Thechute22curves outwardly at its lower end and is-connected to table 26 by a band 88, and this table ha'sa top 27 which is adapted to engage the blanks and. conduct them therealong as they leave the end o'fithechute.

chute for resiliently engaging the formed parts and preventing them from movingout of t-hechutetoo rapidly, as further noted'bee low. On topof the .table26'there is disposed a pair of stringing rods29- for engagingthe blanks as they movegalong the table, and these rods are-used toremovethe stacked parts to other apparatus for furtheroperations."

. The chute f22-is constructed, as shownin Fi g. 2, of twocrosspiecesEO a-nd3-1 secured by sideplates82 and screws 33; The cross pieces 30 and 31 form the passagewayi25 approximating infcross sectionthe outline of a formed blank .34. Y glhese formed blanks usually pos+ sees a number of holes 35, and the stringing rods 29 readily engage the holes and secure the blanks in a stacked formation produced by the guideway or passageway 255 The of the magazining or stacking structure, it is preferable to keep the chute 2 filled at all times with a continuous column of the blanks 3a in order that the blanks may have no chance of turning about themselves or becoming disarranged in the passageway 25. In order to thus fill the chute 22 at the starting of the operation, a retarding'block 40 having lateral springsll, of which only one is shown in Fig. 5, is first inserted within the die-aperture 20. The punch 16 is then actuated to punchsuccessive blanks from the stock 18 into the passageway 25 of the chute, and this. punching of the blanks, of course, gradually forces'the block L0 to the bottom of the chute. Thus it is apparent that the chute becomes filled with the blanks, and. due to the fact that the passage way 25 conforms in crosssection substantial 1y t0 the cross-section of the blanks 34, the blanks become arranged into a stacked col- In the operation After the column of blanks is thus formed the springs 28 at the bottom'of the chute engage the lowermost blanks of the columnand retain the blanks within the chute to preserve the column, and the retarding block 40 is removed because it is no longer necessary in w in Fig. 41 The stacked blanks are inverted.

the, operation. From now on the operation of the stacking chute 22 is apparent. Blanks are continuously punched into. the top of the chute by the punch 16, and as each blank is 'punchedtherein the column of blanks in the chute is forced downwardly the thickness of one blank, and a blank is'forced past the prings28 at the lower end of the chute. ontinuous successive punchingsof the blanks force many blanksout past the springs 28. and onto the table top 27 which conducts the blankginto engagement with thestringing rods 29which engage the holes 35 in the blanks. 'Finally the stringing rods 29 become filled with the stacked blanks and are replaced by other similar rods.

The stringing rods 29 are particularly" applicable for emptying the stacked blanks into a magazine, such as the one designated 42 over this magazine andinserted' therein when the stringing rods 29 are readily removed leaving the blanksstacked in the magazine and ready for further. operations, such as roll formingby a rolling machine 43. 7

Thus it isbelieved to be apparent from theabove description that the invention provides a simple structure for efliciently stacking the blanks and produces a considerable saving by dispensing with stacking by hand when the blanks are indiscriminately passed from the punch press. Furthermore, the novel structure also. produces a significant saving when the parts blanked are thin or bendable when'they would be rendered defective vin casethey'were mixed; together in a pile. Of

course, the structure shown may be modified in various ways, as for instance it may be al tered to stack difierent shaped blanks, or it may be constructed with adjustable parts so tured parts successively formed by amachine,

comprising a chute for receiving the parts from themachme having its recelvlng end extending vertically and its discharge end extending horizontally, a horizontally disposed supporting member positioned in general alignment with the discharge end of the chute and having its upper surface receivable in the recesses of the parts when passing from the chute for maintaining the parts in stacked formation, and a headed stringing member supported parallel to said upper surface by its head and by said parts.
