My invention relates to" improvements in tagforming mechanism'an'd has to do, more particularly, with an --attachment, for a marking machine of the class having a platen and a rocking type-carrying head-which feeds a tape across the platen and'severs the projecting portion of the tape to form-a tag, after a mark has been printed thereon by the marking machine. 7

The principal object of my invention is to pro vide an improved means for-forming a tag, which is adapted to be attache'd'to a marking machine of the type having'arocking type-carrying head, a platen and means for rocking the head to and from the platen; and which is of such a character that tags of variable length may be formed by a relatively simple adjustment.

A further object of my invention is to provide a tag-forming mechanism for attachment to such a marking machine, which will automatically-feed a length of tape over the'platen; as the head 'of the marking machine moves toward the platen, and will automatically sever'the projecting portion of the tape as the headmoves away i'rom the 'platen, after "having'imprinted a mark on said portion of the tape.

Another object oimy invention isto provide a tape-feeding mechanism of such character that the machine can be readily'and conveniently set to feed different amounts of tape at each operation.

A further object-of my invention is to provide an improved tape-severing mechanism for attachment to a marking machineoi the sortreferred to "above; in -which a knife is movedacross the tape to sever it in the forepart of-the return stroke of the -marking machine head, and auto-' matically returned -to normal during the latter part "of said 'return 'stroke.

A further object of: my invention is to provide tape severing means'dorming a part "ofa tagforming mechanism, which is provided with manually-operable means for rendering the'tape-' severing means "ineffective.

wI'lurthe-r ohjectarand' tob-iects' relating to-"details ofconstruction and economiesof operation, will definitely: appear P firom the detailed "description to follow. i'ln oneiin'stancefI have accomplished the: objects ofmyd nvention by-the devices and means: described in the following specification. Myi'inverrtionis clearly defined and pointed out in the? appended claims. structure "constituting a-:'1: referredembodiment of my'invention is illustrated. inthe accompanying"drawings-f forming a part oi this-speci'fication, in which *2 ing machine having-my improv d t m. ing mechanism attached t-h t Fig. 2 is a view in side elevation of said marking machine and tag-formin=g mechanism.

Fig. 8 is a detail, sectionalview taken "on the line 88 of Fig. 3, and I Fig. 9 is a fragmentary view-insideelevation of the mountingfor the tension rolls,-"between which the tape passes to the tape-feeding device.

The same reference numerals refer to the same parts throughout the several views, and the sectional views are taken looking in the direction of the arrows at the ends of the section lines.

In general, the tag-forming mechanism of my invention com-prises meansior feeding tape "over the platen of a marking'machine, that is actuated by the rocking of a type-carrying head toward said platen, and meansforsevering the portion of the tape fed over the platen, that is'actuated Fig. 'i isa view in front elevation of part-of 'aby the rockingof said head away f'r'om' the platen.

The means'for feeding tape over the platen may comprise a carriage 'movable along a 'gui'deway for directing'the' tape toand' over the'platen; and

means for moving the-gcarriage toward the platen actuated by the rockingof' the type'carrying head toward it. The means for feeding the tape toward the 'pl'aten-may 'includ'e spring meansfor: moving said carriageaway from thepiaten, during the return stroke of thetype-carrying head.

The means for'feeding the tape to and over the platen may include a'means for gripping the tape. which gripping means is moved toward the platen by the rocking of the type-carrying head toward it; gIthmay include means for -automati cally re-.

leasing the gripping-means,"to-"freethe tape at a predetermined point in the movement of the gripping means toward the platen. It may also include automatic means for causing the gripping means to grip the tape, at a predetermined point in its movement away from the platen. The tape-feeding means may well include a guideway for the tape, on which a carriage is movable toward and from the platen upon the rocking of the type-carrying head of the marking machine. This carriage may have clamping means which are caused to clamp the tape, at a predetermined point in the movement of the carriage away from the platen, and caused to release the tape, at a predetermined point in its movement toward the platen.

The tape-severing mechanism forming part of my tag-forming attachment may include a pivoted blade, that is normally out of the path of the tape fed over the platen, together with means for moving the blade across the path of the tape to sever the end thereof, actuated by the rocking of the type-carrying. head of the marking machine away from the platen. It may also include means for returning the cutting blade to its normal position, automatically rendered effective at a predetermined point in thev return stroke of the marking machine head. The means for rocking the blade to sever the end of the tape may take the form of connections between the head of the marking machine and a pivoted drive plate, having a pin and slot connection with the blade, which connections are efiective at the beginning of the return stroke of the head. It may also include automatic means for disabling these connections, at a predetermined point in the return stroke of the head. Manually-operable means for rendering these connections ineffective may also be provided.

Referring to the numbered parts of the accompanying drawings, I have shown my tag-forming attachment in connection with a marking machine, indicated generally at I0, having a frame H and a rocking head l2, pivoted at l3 and carrying a plurality of type wheels, indicated genorally at |4. The marking machine includes'a platen l5, supported by frame Means (not shown) are provided for rocking the head l2, so as to carry the type wheels l4 toward and away from platen |5. The type wheels l4 having been adjusted, in any desirable manner, to present type at the printing line to print the characters of the mark, the head |2 is rocked and the type wheels descend to press the selected type against material supported on the platen l5 and print the mark thereon. The head then rocks to carry the type wheels away from the platen to normalposition.

A plate |6, secured to theframe II, has a slot l1 therein, at the level of the top of the platen l5, and the tape, from which the tag is to be formed and to which the: mark is to be applied,

is fed throughthis slot onto the platen IS. A. 5 horizontal bar l9, having a longitudinally-extending slot 20, has a vertical flange 2| applied to the outer face of a spacingplate'lB, which is applied to the outer face of plate It, and flange 2|, plate I8 and plate l6 are secured to the marking machine frame in any suitable manner. The base 22 of a U-shaped member, having the legs 2|, i also applied to'the outer face of plate l8 and secured, in any suitable manner, to the frame of the marking machine.v The legs '2! extend generally parallel to the bar l9 but are 10-- cated somewhat below it. The outer end of bar |9 is supported by a Ll-shaped bracket 23, the

legs of which are secured to the outer ends of legs 2|, by a bolt 24. Two strips 25, extending parallel to slot 20, are disposed on the upper face of bar l9 adjacent the edges thereof. These strips 25 are considerably narrower than the portions of the bar 9 on each side of the slot 20. A pair of parallel top plates 26 is secured in position over the strips 25, being so spaced apart as to leave between them a slot 21, parallel to and of substantially the same width as slot 23. These parts are secured together by bolts 28 to form a guideway for directing the tape to and through the slot l1 and thence over the platen i5, and this guideway comprises a longitudinally extending slot and a pair of lateral channels opening into said slot from opposite sides for receiving the edge portions of the tape T.

L-shaped brackets 35 have their horizontal arms 29 secured to the legs of the U-shaped bracket 23, as shown inijFigs. 5 and 9. A lower roller 32 is mounted on a shaft 3|, the ends of which extend through the elongated slot 33 inthe brackets 30. An upper roller 35 is mounted on a shaft 34, the ends of which also extend through the slots 33. The tape T passes between the

rolls

32 and 35 and thence to the guideway, which directs it toward the platen, and these

rolls

32 and 35 constitute tension rolls putting a slight tension on the tape, as it is fed to the platen. A yoke 36 is pivotally mounted on the projecting ends of the shaft 34 and has cam surfaces 31 (Fig. 9) adapted to engage the projecting ends of the shaft 3|. It also has notches 38 adapted to engage the projecting ends of said shaft 3|, when the yoke 36 is rocked on shaft 34 to move the rolls away from each other. Springs 39, one at each side of the yoke 36, have their upper ends connected to the projecting ends of shaft 34 and their lower ends connected to pins 40 carried by the brackets 30. A key tip or handle 4| is secured to the yoke 36, for convenience in rocking it about its pivotal mounting. When the operator presses down on the key 4|, yoke 35 will be rocked counterclockwise (Fig. 9) about the axis of shaft 34, and the cam surfaces 31 engaging the shaft 3l, which abuts the lower ends of the slots 33, causes the shaft 34 to be forced upwardly in said slots against the tension of springs 39, thus separating the

rolls

32 and 35 to remove the tension on the tape. Engagement of the ends of the shaft 3| in the notches 38 retains the yoke 36 in this position, in which the rolls are separated.

The roll of tape T is mounted on a spindle 42 carried by the lower end of a strap 43, the upper end of which is fastened to one of the legs 2| of the U-shaped bracket 22.

Plates

44 and 45 are mounted on the spindle 42, on opposite sides of the reel of tape and in spaced relation, and angular brackets 46 are secured to the periphery of plate 45 and extend laterally toward the edge of plate 44.

Brackets 4'! are mounted on the guideway, at

and this block has a laterally-extending boss 54,"

the interior of which is hollowed out to form a recess, A plunger 55 i slidably mountedjin as es:

said boss and the tip thereof is adapted to project into any one of the sockets'i50 in the stop rail. A flange 51 on the plunger56xisislidab1e in the recess 55 and spring 58yis: compressed between flange 51? and sleeve 59, which closes the outer end of recess 55. A milled-head 60 is'fixed to the outer end of plungeri 55, byrmeans-of which it may be withdrawn against. the-:pressure of spring 58, so as to withdraw the projecting end from the socket 5B and permit adjustment of block 52 on the stop rail 49 to a new position. An indexing strip 6| is fastened to the: upper. surface ofthe stop rail 49 andhasv a plurality of characters thereon,- indicating different lengths of'tape feed. Indexing marks 52 formed on the top of the stop block 52, when oppositexone of these characters on strip 6 I, indicate that the block is inv line with that'one of the sockets 5!!- that willgive a tape feed of corresponding length.

A tape-feeding carriage isprovided, (which comprises'a'base BS'eXtendin-g beneath the guideway and having upwardly-extending portions 64 at thersides thereof ,rwhich extend along: the sides of the guideway. "The: carriage includes,.also, a

top plate-65, which is secured to the base 63 by bolts fifirextending through the top plate 55 and the portions .64 ofsaidbase. A clamping member- 61, the upper portion. of which is preferably milled or roughenedyis secured to the base 63 of the carriage by the screw-=68, and extends into the slot. 20, the upper surface of the member 61 being about on a linewith the lower walls of the lateral channels formedinithe guideway, and hence below the path of the tape. The top plate 65 of the carriage. isprovidediwith aboss B19 in which a plunger HI isslidably-mounted. This plunger has a head 1-I.,-which is disposed in the slot 21 or the guideway, and the lower surfac of this head. is milledonroughened. -A spring'lZ surrounds the plunger "I0 and isinterposed between the top of theboss 69 and a'transverse pin I3, carried by the upper end of the: plunger. This spring tends to move the plungerIU upwardly in theboss, so as torcarry the head I I :away from the tape. The upper end of the plunger is "provided. with a point M-andcam surfaces on each side thereof. Legs E6 of a yokemember arepivotedto the carriage at E1, and the cross-member I8 of'thisyokeis adapted to engagewthe cam surface 15 and the tip '14,, when the yoke is rocked clockwise, to depress the plunger. i-il againstithe pressure of spring I2 and force the head-I1 against the tape to clamp it-wagainst th clamping member 61.

This prevents further rocking movement of yoke 16 in that direction and the stop block 52, yoke 16' and stop 8! constitute means for limiting the movement of the carriage away from the platen. Obviously, the point at which the carriage will be stopped, in its movement away from the platen, may be varied by varying the position of stop block 52. Movement of the yoke 16. in-the other direction, is limited by engagement :of the edges 82 with the top of plate 65 of the carriage.

The headed screws 83, having. shoulder portions 34, aresecured to and projecttfrom thesides of the carriage, and the shoulder portions of these screws are locate-d in the elongated slots-85 of arms 86, one at each-side of the carriage, which -are fast on atransverse shaftil'l journaled in the legs. 2| of the U-shaped bracket 22. Ancarm 88, also fast on the shaft. 81-, has connected thereto one end of a spring 39, the other-end of whichspring is connected to a bracket'fill secured-to the frame- II of the marking machine; 'An operatingiarm 9|, also fast ontheshaftBI, has a U-shaped bracket iilpivoted thereto at '93,-and the-legs of the bracket 92 have elongated openings '94 there'- in, through whichthe pitman 95 extends; The upper end of pitman-95 ispivotal'ly connected, at 96, to a bracket 91 fastened to the head I-Z of the marking machine. A nutor:other.suitab1e abutment 98 is mounted onthe pitman 95. When head I2 is rocked to ca-rry the type wheels I4 toward the platen Iii-,pitman-95.:descends'and abutment 98 engages member 92 and rocks shaft 81 clockwise in oppositiion to spring 89, so as to move the carriage toward. the platen.- As per-- mitted by the ascent ofpitman 95 during-there turn stroke ofthe head, spring 89 moves thecarriage away from the platen.

As shown in Fig- 5, the-guide plate" Iii, havingthe slot IT therein, is mounted on the'frame II of the marking machine adj-acent'one endoi platen I5, with the slotI T on a level with the top of the platen. This plate It (Fig. 4:) has a lateral ear 99, to which a blade-supporting arm Hit is pivotally connected at IilI. This. arm extends upwardly, then rearwardly and, then, downwardly; being arched over the upper end of guide plate I6. Ablade N12 is secured toqarm I-Ofland, as shown in Fig.1 5, bearsiagainst the side of. guide plate I 6 adj acent: platen I 5.

depends therefrom alongside the stud H4 onv is' in the lower position in which thetype wheels I4 engage material on the platen l5, notch II! will be in position to hook under the stud I I4 on drive plate I06. A spring H8 fastened, at one end; to the lower end of link H5 and, at H9, to a partof the-marking machine frame, tends to draw link H5 toward stud II 4, so as to cause it to hook undersaid stud when head I2 reaches the bottom of'its stroke. A stud I06 on drive plate I06'is adapted to engage bracket I08 to limit "counterclockwise movement of said drive plate. A lug I20 is 'adjustably mounted on drive plate I06, by means of a screw I22 passing through aznot'ch I2I in the base of the lug, and this lug isso lo'cated that, as drive plate I06 rocks clockwise in opposition to spring H2, it will engage the lower end of link H5 and crowd it laterallti soas'to unhook it from the stud H4. A link I23 ismivotallyconnected, at I24, to the lower end of link H5, and said link extends through loop I25, carried by a suitable portion of the frame-' work, and has a key tip I26 at its forward end. Pushing rearwardly on the link I23 will hold the link H5in inefiective position against th'e'pressure of spring I I8, thus disabling the tape-severing mechanism.

The frame II of the marking machine,'adjacnt the platen I5, is provided with a pair of spaced brackets I21, in which the portion I28 of a flipper member is journaled. This member extends laterally at I29, past the end of the platen,

and thence extends, at I30, parallel to the portion" I 28 but on the opposite side of the platen.

A'torsion spring I3I surrounds the portion I28 of the flipper between the brackets I21, one end I l of said spring being fastened to one of the brackets, while the other end is fastened to a nut I32 secured to the portion I28 of the flipper. The head I2 of the marking machine has a spring arm I33 secured thereto which has a tooth I34 adapted to snap under and engage under the portion I29 of the flipper at the end of the downstroke of the head. As the head moves upwardly on the return stroke, the tooth I34 rocks the flipper against the tension of spring I 3I,'until tooth I34 clears the portion I29 of thefiipper, when spring I3I returns it to normal position. This serves to flip from the platen, the tag that has just been formed by severing the projecting portion of the tape.

The operation of this tag-forming mechanism should be apparent from the description given above, but it will be described briefly, as follows:

The tape T passes from the roll of tape on spindle 1 42 upwardly and between the tension rolls 32 and held in depressed position by the cross-member I I8 of yoke I6. As the marking machine is op- 1 erated and the head I2 rocked to carry the type wheels I4 toward platen I5 pitman 95'descends and abutment 98 thereon engages member 92 carried by the operating arm 9| and rocks the shaft 81 clockwise, against the tension of" spring 89.

This rocks arms 86' clockwise, and thereby the carriage, including'base 63 and top plate 65, is moved from the position shown in full lines in Fig. 5 toward the plateh'to the position indicated in dotted lines, in that view. Since the tape is clamped to the carriage, this moves the tape in the channel of the guideway and through the slot I'I, so that a portion of the tape projects over platen I5. 'As the head nears the end of its downstroke, arm of the trip member is engages the projecting end of the trip pin 5i on stop rail 49, and thereby yoke I5 is caused to rock counterclockwise to the position indicated in dotted lines. permitting it to rise under the pressure of spring I2 so as to free the tape, and the feeding of the tape ceases at that point." Shortly thereafter, the type wheels I4 engage. the projecting portion of the tape on platen I5 and imprint the mark thereon. As the head I2 moves upwardly on the return stroke, abutment 98 moves away from member 92 and thereby spring 89 is effective to rock shaft 81 counterclockwise and move the carriage away from the platen. When, in such movement, arms 80 engage the stop block 52, yoke 76 will be rocked from the dotted line position clockwise to the position shown in full lines in Fig. 5', which depresses plunger 10 to clampthe tape against the clamping member 61. Engagement of the cross-'member I8 of the yoke with the stop 8i prevents further movement of the carriage away from the platen. As the carriage'moves away from the platen, plunger It is in its elevated position away from the tape, so that the carriage moves relative to'the tape, but,

at the end'ofthe movement of the carriage away from the platen, the plunger I0 is automatically applied to grip the tape as stated above. At the next stroke of the marking machine head, the

feeding of the tape will be repeated as described ing the plunger 56' from a socket 50, sliding the block along the rail, and allowing the plunger 56 to be engaged by spring 58 in another one of the sockets 50. v a

When the head I'2 of the marking machine is in normal position, spring H8 (Fig. 4) holds the lower portion of link I I5 against the side of stud I I4 and spring H2 holds the drive plate I06and the blade-carrying arm I90 in the positions shown in Fig.4. When the head I2 reaches the end of its downstroke, spring I IB-moves the lower end of link H5 laterally, causing the notch II! to engage under the stud H4. This automatically establishes the driving connection between the marking machine head and the drive plate. As the head moves upwardly on thereturn stroke, the engagement oi. link I I5 with stud H4" causes the drive plate I06 to be rocked clockwise against the tension orspring H2, and this causes'the' blade-carrying arm I00 to-be rocked counterclockwise, carrying'the blade I02 across the path of the tape extending through slot I'l so that it severs the portion that has been fed over the platen during the downstroke of the marking machine head. drive plate I06 rocks clockv'vise,lug I20 is carried againstthelowerend of link H5 and crowds it laterally, so asto unhook it fromthe stud H4, and thereupon spring H2 is at once effective to rock the drive plate I05 counterclockwise, and the blade-carrying arm IOII--clockwise, to restore" these parts to their This frees the plunger 18,

normal positions. If it is desired to disablethe tape-severing mechanism, thismay be accomplished by pressing rearwardlyon'the' key tip I26, which moves the link I23 rearwardly, thus movin the lower end of link H to the rear against the tension of spring l is, and preventing. engagement of notch 11! with stud H4 at the end of the downstroke of the-markingmachine. head.

I am aware that-the mechanism shown herein may be varied considerably without;departing from the spirit of my invention and, therefore, I claim my invention broadly as indicated'by the appended claims. i
