.6 Claims. (Cl. 140-431) This invention relates to improvements in wire stitching feeds, the feed being incorporated in a type of wire stitching machine wherein the wire is fed intermittently to a staple-forming and driving mechanism.
A general object of the invention is to provide a simple and easily adjusted Wire stitcher feed mechanism which is susceptible of readjustments to compensate for wear on a wire feed segment and which is also readily adjustable to permit variations in the feed of the wire to regulate the ultimate length of the staples formed and driven by the wire stitching machine.
A more specific object of the invention is to provide, in a wire stitching machine, cooperating wire feed rollers, one of which carries a yielding feed segment cooperable with a fixed segment in the other roller, said yielding segment being readily adjustable to compensate for Wear on its work surface.
Another specific object of the invention is to provide a wire stitcher feed wherein the cooperating feed rollers are formed with registrable graduations, with one of the rollers being readily adjustable to advance or retard its graduations relative to a graduation on the other roller for indicating the length of staples to be produced.
A further object of the invention is to provide a wire stitcher feed which is of very simple construction, is easily manipulated, adjusted, and serviced, is strong and durable, and is Well adapted for the purposes described.
With the above and other objects in view, the invention consists of the improved wire stitcher feed and its parts and combinations as set forth in the claims and all equivalents thereof.
In the accompanying drawings in which the same reference characters indicate the" same parts in all of the views: I
Fig. 1 is a fragmentary front view of the upper portion of a box stapling machine embodying the improved wire stitcher feed;
Fig. 2 is an enlarged fragmentary view of that portion of the wire stitching machine with which the wire stitcher feed is associated, with the feed rollers contacting the Wire prior to the advancement or feed of the wire, parts being brokenaway and in section;
Fig. 3 is an enlarged fragmentary detailed view, with parts broken away and in section, and similar to Fig. 2, only showing advanced positions of the feed rollers resulting in the feeding of an extent of wire;
Fig. 4 is a transverse, vertical, sectional view taken on line 4- -4 of Fig. 2 and on a larger scale;
Fig. 5 is a transverse, vertical, sectional View taken on line 55 of Fig. 2 and on a larger scale;
and
Fig. 6 is a fragmentary front view of the wire feed rollers and the portion of the stitching machine with which they are'associated, with the rollers in a different position of adjustment than that shown in Fig. 1.
Inasmuch as the invention is concerned pri-' maril with wire feeding mechanism incorporated in a wire stitching machine, it will not be necessary to describe in detail the entire ma-v chine in which said improvements are incorporated. As shown in Fig. 1, the machine includes a massive, hollow, vertical pedestal 8, on which is mounted a horizontal stitcher bar 9 which re ceives the work to be stapled. Above the stitcher bar 9 and properly spaced relative thereto is a staple cutting, forming and driving mechanism, indicated generally by the numeral Ill. The moving parts incorporated in the unit ID are controlled through the operation of cams H and i2 mounted fast on a horizontal clutch-controlled shaft I3. The latter is driven through'connec-y tions with an electric motor (not shown).
The forward end of an elongated stretch of wire I4, preferably flat in cross-section, enters unit ill to be successively cut into suitable pre= determined lengths therein, which lengths are then bent and shaped into staples which are driven into superimposed thicknesses of paper board box walls mounted on the stitcher bar 9. The wire [4 is unwound from a reel I5 which is freely revolubly mounted on a spindle I6 supported from a frame arm I! extending above the main portion of the machine.
A yielding wire guide and reel brake isindicated generally by the numeral Hi. This member is the subject matter of my Patent No. 2,442,933 and supports the wire unwound from the reel 15min the manner shown, guiding it to and through a wire feed check It and from thence between the adjacent peripheral portions of a pair of feed rollers 20 and 21, which are one of the particular features of the present invention. After the wire leaves the feed rollers, which are effective to intermittently pull desired lengths of the wire from the reel, the wire passes through a curved guide 22 and. from thence to the staple-forming and dIiVing mechanism l0.
A wire straightener 59 comprises a U-shaped bracket adjustably seated on and embracing any selected portion of the outer arm of the wire guide l8. It is held me selected adjusted position'by .55 a, clamping .bolt to having its shank portion sta es. is'ave for the wire Ifeed :eheek :19.

. feed roller is positively driven through the medium of the usual gearing which extends to and derives its power from the shaft l3.
To'obt'ain an intermittent feed, only a portion 6f the peripheries ofthe feed rollers and 2i are employed. Thus, the feed roller 2| has withlin its wire receiving peripheral groove a fixed (feed segment 25. The companion feed roller 20 has within its peripheral groove an adjustable andyielding feed segment 25, best shown in Figs. -2 and 3,- and comprising a relatively thin shank portion 25' arid athicker work section 26", the
outersiiifac of the latter being outwardly offset from th correspohding surface of the portion -25. The shank portion 26' of said feed segment 25 is pivotally mounted on a wheel-carried pin 27. The work section 25" of said feed segment is constantly urged radially outwardly by a coiled spring 28 confined within a recess in the "feed roller12fl. Arset screw 29 is adjust-ably threaded into the wheel :20, radially inwardly with respect to :the groove of said wheel and the outer end portion of asid set screw underlies'theinner end of :the pivotal feed segmeht tfi; l he adjustment of said set screwarelative to the feedsegment de= termines the amount of yielding :pivotal move= merit said 1 feed segment may have.
During operation of "the wire :feedi'ng mech' anism it is, of course evident that the outer en-' gaging surfaceof-the work section ZG' of thefeed segment 26 may be'subjected to wear which will efiectdts grip and'e'fficien'cy. The :mounting of said feed segment and its arrangement is such that'after wear hasimpaired-said feed-segment, the effective :surface thereof may be reground and -.a resetting of the set screw 29 :will com pensate for 'an-y'reduced thickness in the portion 25" of the feed segment due to grinding.
In Fig. 4 there is illustrated the manner in which thefeedroller 20 is assembled with its associated parts. The driving gear "23 rest on'the reduced inner-end of a ceiitral hubniem ber 80 :and is additionally secured thereto by :-a pin =-3I. The forward end portion of the "hub member =3D'is slightlyreducei'and the feed roller 2i: isxkeyedonto' said'reduced portion of the hub member. The-entire assembly is secured together by an axial bolt 32 'whose outer end 'has "thread ed thereon a nut 33. When the nut is tightened, an interposed plate *34 clampingly bears against the outer endofrthe hub m'ember.
Fig.5 illustratestl'leimann'er in'tvhich thecoinp'lenientary feed roller "2! is -asse1nbled"with =its associated-parts. .The reduced inner :end po'r ticn ofca hub member 35 hasifast'ithereon:the operating gear'24, previously mentioned, a' pin 35 aiding in the securement of the gear. The forward .eh'd portion fer the hub member "35 is 'sli'glitly.-reduced; andthe feed roller 2| iskeyea onto said reduced portion. The feed segment 2 -5 'orifsaicl feed roller -2l is'in fact an inwardly directed'flangeionaroller plate 3'1, and said plate isaahgularly adJust'able:relative to 'the feed roller 2! .t'o va'ry the disposition of the segment flange 25. thatpurpose the plate 31 is Provided with an outwardly projecting manipulating knob against ithe outer face of the re'ea roller :2 so 'as"tt )ltlll'n tllefwith *by'means or a bblt 39 and a clampiiig plate lil. "However, when the bolt 39 is loosened, by means of the knob Kil -the plate 3l "may hemmed elr'cularl' b -adv'anee 'or retard the :reee.- =segmentinangier25 reiative'te the feed roller 2|. It is, in this connection, convenient to have a face portion of the plate 31 formed with spaced graduations M, and the registration of a desired graduation 4| with a graduation 42 on the face of the complementary feed roller will. determine the length of contact of the effective portions of the feed segments and 26, and hence the amount of intermittent feed of the Wire l4 and the ultimate length of staple to be formed.
Assuming that the staple-cutting, forming and driving mechanism ID has been set for operation on staples of a desired length, then the disc 3'! is set so as to register the selected graduation 4! with the graduation 42 on the feed roller 20, to provide for the length of intermittent wire feed. With the machine then in operation and through the train of gears and the roller carried meshing gears 23 and 24, the feed rollers 20 and 2| will revolve toward each other in opposite directions. The extent of wire l4 passes between the meeting peripheral portions of the feed rollers 20 and 2! and, due to the grooved formation of the feed rollers, turning movement of the feed rollers is ineffective to engage and advance the wire until the portion 26" of the feed segment 26 comes into contact with the feed segment 25 of the feed roller 2|. As long as said portions of the feed segments are in contact, the wire will be squeezed therebetween and will be pulled downwardly a desired advanced extent, suitable for the formation of a staple. There will be cessation in the advancement of the wire when the feed segments are out of contact. In Fig. 2 there is illustrated the relation of the feed segments to the wire before the effective portions of the feed segments are in mutual engagement, and Fig. 3 illustrates the relationship of the parts just as the intermittent feed is about to terminate, with the portion 26" of the feed section 26 terminating its contact with the feed segment 25. The
yieldability of the feed segment 26 permits proper clamping engagement of the same with the wire and the set screw 29 is important in regulating the proper position of the feed segment and limiting its amount of yielding pivotal movement.
Mounted on a bracket portion. of the machine with its open upper end alined with a tangent to the meeting peripheries of the wire feed rollers 20 and 2|, is a curved wire feed guide 22. This member is adapted to receive the wire after it passes the feed rollers and to direct it to the staple cutting and forming mechanism 10. Throughout the length of the member 22 there is a curved internal cavity through which the extent of wire I4 passes. The upper end of the wire receiving portion of the member 22 is enlarged, as at 83, for better receiving and directing the wire. The major portion of the wire receiving extent of the curved wire guide is open along its outer side, as at 84, and the cavity is substantially oval to conform with the fiat shape of the wire to eliminate friction and clogging and to enhance the feeding of the wire. The open construction of the guide permits the guide cavity to be easily rid of dirt which might lodge therein or surface material rubbed from the moving wire, it being appreciated that an accumulation of such material within the wire guide cavity might clog the same and prevent free or easy movement of the advancing wire. The open side to the cavity makes the construction practically self-cleaning and permits ready lubrication of the interior of the cavity and the Wire passing therethrough. It will further be observed that a flattened side flange portion of the-member 84' is removably bolted to a supporting portion of the machine by bolts 85, whereby removal of the unit is permitted for easy repairs, cleaning. or replacement.
The improved wire stitching feed mechanism very adequately provides for the intermittent feed of the wire in desired lengths and the feed rollers are readily adjustable and removable from their assemblies for repairs and replacements. W'ear which may occur on the effective surface of the segment portion 26" may be easily remedied and compensated for. The improved wire stitching feed mechanism is simple in its operation and construction and is well adapted for the purposes described.
