EEFEMIEIEIUIIM i Lg *rn ,rare aan ADAM BLUEGE, O F CHICAGO, ILLINOIS.

To all whom 'it may concern:

Be it known that I, ADAM BLUEGE, aciti-` zen of the United States, residing at Chrv cago, in the ,county of Cookand State o f.

Illinois, have invented certain new and useful Improvements in Cutters, of which the following is a specication.

This vinvention relates to cutting machines ofthe type designed for ysimultaneously seyering several strands .of wire, used particularly for binding the sides of what are known as wire bound boxes.

1Wired or wire bound boxes are, at the hpresent time, manufactured 'by machinery whereby the four sides of each box are se- "..cured together by a plurality of continuous 'strands of wire, said Astrands being discharged from the machine uncut irrespective of the number of 'boxes secured thereto,

there being only a space between each pairof boxes. lvlanifestly, therefore, 1t -1s necessary to sever orcut the continuous strands of wire at the spaces between the adjoining boxes and this is now done manually.

It is the obj ect of fthe present invention lto provide an attachment for the machines usedvin manufacturing Wire bound boxes' which will automatically sever or cutfsimultaneously all of the continuous strands of Wire at the spaces between the boxes and which 4will receivefthe strands of Wire with the boxes secured thereto-directly f -rom `the box machine.

-lVhile theA present invention is disclosed and described .as being particularly adaptable as an adjunct gto a machine for manufacturing wire bound boxes, it has `Immerous uses and is not to be construed as being so limited.

With the aboveand other objects in view,

as will be hereinafter apparent, this 4invention consists in the construction combinal tion and arrangement of partsyallas hereinafter more fully described, claimed, and

illustrated in the accompanying .drawings constructed in accordance with the present l invention, illustrating in dotted lines box elements passing therethrough;v Fig. 2 is a.

plan view thereof likewise illustratin the box .elements and binding wires vin idotted lines; Fig. 3 is a vertical section taken along line 3 3, Fig. l; Fig. 4 is anend elevation .upright 4Specification'of Letters Patent; Patented Jung, 1915. Application ledllecember 5,119.14. Seria1'NQ.875,650.

ofthe machine; and Fig. 5 is a sectiontalien -f i along line 5 5, lig.l 4, to illustrate lthe power clutch mechanism.

i Y-.doitted linesin all of the figures is A frame comprising the legs 13, .the cross 'bars 14, and the braces 15, constitutes the main support of .the ipresent'machine, said braces 15 being cylindrical `in cross section.A `Mounted upon .the bracesl Aadjacent to the cross bars 14 are Ithe runners or tracks 16 which, atthe inlet or feedend of the machine,

extend beyond .the adjoining brace 15 and are curved downwardly as at 17 to constitute guides for directing ythe box elements 10 and binding wires 11 to the cutting mechanism hereinafter described.

An upright 18 having a central vertical slot 19, open at one end, in its upper Aterminal is secured to each cross bar 14. by means of the bolts 2O which pierce-not only the cooperating cross bar but also a transverse base 21 formed onthe non-slotted end of the These uprights in combination form a superstructure which carries thecut- Iting mechanism fOr operation upon .the

Lbinding wires 11 passing thereunder.

The cutting or shearing mechanisms are mounted ,between the uprights 18 and operate Ain the slots 19 4and comprise a carrier bar 22 ,arranged transversely .between the uprights 18 Sand .having its ,ends located Ain the slots 19 vfor .a vertical movement. An

operating bar 23 is similarly .located above the vcarrier bar 2 2 and .is :mounted for *reciprocatory vertical movement in the :slots 19 of the uprights r1 8.

Each of the .cutters or shears 24 has one arm 24 pivoted' to the carrier base 22-and opposite arm 2,41extended and slotted as at i.

24a for engagement with the pin 25 of the operating bar 23. In this manner-when the operating bar 23 rests .approximately flush against the carrier bar '-22 the cutters or shears 24 are open; but when the operating bar 23 is raised and freciprocated all ofthe cutters or shears .24 are closed and opened alegato simultaneously shearing or cutting all of the binding wires 1l located between the cutting portions thereof. -As illustrated in Fig. 3 the arms 24 and 24l of the shears or cutters -24 are offset and rest -flush against the together. 1n order to accomplish lthis movement an oscillatory rod 26 is secured between the rear ends of the cross bars 14 abovethe adjoining brace 15 5and in the same 'vertical plane therewith, said rod 26 piercing and extending beyond the cross bars 14.

An operatingl finger 27 is adjustably secured to the rod 26 by means of a block 28 and a set screw 29, said finger 27 having its free endrebent to form a contact or bearing member 30 which rests insubstantially the same verticalv plane as the shears or cutters 24. This contact or bearing 30 is so lo-` whereas when the contact kor b'earing 30` rides'upon the' next unit of boxl elements 10, the finger 27 is movedupwardly and the `rod 26 is oscillated in the reverse direction.

The oscillation of the rod 26 is designed to set into operation mechanism` for raising and lowering the cutters or shears 24 and to reciprocate the operating bar 23.` .n

Secured to' the projecting terminals of the rod 26 are the arms 31 which are adapted tobe moved as the rod 26 is oscillated. A

pitman 32 connects the free end of each arm '31 with .thecorresponding and projecting `end of thecarrier bar 22 so that when the rod 26 is oscillated downwardly, the said carrier bar 22 will likewise move downwardly bringing the binding wires 11 between thecutting or shearing portions of the shears orcutters 24, and vice versa. The op erating bar 23 at one end is connected by the links 33 to the' adjacent end of Athe carrier to said carrier bar by means of the belll ybetween said pedestals.

having the loose pulley 37 mounted thereon A clutch element 38 is slidably mounted on the hub 37 by means of a bell crank 39 pivoted, to one of the ypedestals 36. Keyed to the shaft 35 against longitudinal movement on said shaft is a second clutch member 40 arranged to engage with the clutch member 38 at predetermined intervals to impart one revolue tion to the shaft 35. rl`his is accomplished by a pin or projection 41 on one end of the pedestals 36 which whenvthe shaft 35 and clutch element 38 have completed one revolution engages a cam 42 on the adjacent face of the said clutch member 38 and disengages it from the clutch member 40:

For connecting the shaft 35 tothe free ends 34 of the bell cranks 34 for oscillating the latter and reciprocating the operating bar 23 a crank 43 is formed on the inner end of said shaft, which crank has an eccentric arm' 44. A pitman 45 forms a connection between the crank. 43 and the bell cranks 34. In this manner when the clutch members 38 and 40 are in interengagement a single rotation ofI the shaft 35 causes the operating bar 23 to reciprocate bringing 'the arms 24 and 24 of the shears or cutters 24 together to sever or cut the binding wires 11. Previous to this movement, however,the finger 27 and arms 31 have moved downwardly to bring the shears or cutters 24 into operative relation with the binding wires 11 and it is this movement that oscillates the bell crank 39 to bring the clutch members 38 and 40 into locking engagement. For this purpose the free arm of the bell crank 39 has a slotted connection with ythe lower end of the link 46 which is. pivotally connected at-its upper end to the adjacent end of vthe carrier bar 22 so that when this bar moves downwardly the bell crank 39 will oscillate to bring the clutch members into interengagement.

After the wires 11 have been severed and prior to thecompletion of the single revoluthe bars 22 and 23 in a similar direction to their initial position so that the passage of the next unit of boX elements 10 may have an unobstructed passage under the cutters or shears 24. To accomplish this, the eccentric arm 44 of the shaft 35 has a pitman 47 pivoted to its free end, said pitman having a slotted extension 48 for engagement with a pin 49 carried by the adjacent arm 31. During the cutting or shearing operation the slot of the extension 43 is such that the crank 43 may rotate without affecting the arms 31; but upon the completion of the cutting or shearing operation the wall at the end of .tion of the shaft 35,'it is necessary to move ias the slot in the extension contacts with the l pin 49 and elevatesthe arms 31 andi'inger 27 so that allof the parts are returned to their original positions.
