In the present invention thetag after it has been severed from the strip is passed or dispensed transversely of the strip` appropriately over clenching mechanism for driving foods to 4be ticketthe ends thereof. y

igures 5, Gand 8 of the ed and cleichin Referring to drawings, 22indicates a pedestal fixed upon the base '1, with the head of the pedestal in the form of a table 2S for` supporting the tag stri `24. The tablel is loiigitudinally slotted or c anneled -to ,receive and track the depend- A ing prongs of the metallic fasteners or staples 25 with which each tag of the strip is provided.

The strip is a commercial product of cardboard material Ahaving definitely spaced notches cut inward from one longitudinal edge thereof, each to be successively engaged by a feed finger 26, reciprocating' with a slide or carriage 27. The feed finger 26 is pivotally mounted andfyieidingly depressed within the forked `or slotted lower side of`a spring y'pressed plunger 28- slidably mounted within a holder 29, (see Figures 18 and 19k) fixedupon the carriage. The forward end ofthe ,finger is appropriately shaped to engage into 'a notch of the tag strip with the forward stroke of the `carriage for advancing the strip awdetermined or measured 'degree moving a foremost 'tag of the strip beneath the finger moves with the carriage until the forward end engages against a rigid stop, which constitutes a knife or movable cutter die for severing the" tags from the l strip. The plunger is yieldingly engaged within the holder to accommodate for carriage movement to the end of its stroke and forany increment .carriage movement over'that of rintingI mechanism for printingthe 'pri' e marking or other data' thereon. -The I the finger after the finger is engaged with the abutment. The fingen advancing movement is 'thus definitely arrested for limiting the advancing motion of the strip and bringing a notch thereof successively into positive registration and alignment with the cutter or cutting dies, the dies cutting across the strip cam wheel 33 fixed tothe shaft 10 (see Fig? continuous with the notches inisevering the tagffrom the strip. l he front end of the finger and the rear end of the movable cutter or die are of a construction which will permit the notch engaging end of the finger to pass beneath the die wlth the butt end of the finger engaged against the side of the die, the die having its cutting edge forward yof the point of finger engagement.

rlhe carriageslidesupon an angle guide plate 30 fixed to the pedestal at the rear side of the table and a horizontal portion of the plate overlies the table 'adaptin the carria e to be guidingly sustained over t 1e table. Te carriage is reciprocated by a lever 3l havin its upper end forked to engage with a heade pin 32 fixed to and extending from the-side of the carriage and the lever 31 intermedially is `provided with a lateral extending roller engaging in the cam groove in the side of a ures 7 and 8). In'each advancing step of the tag strip, the foremost tag of thefstrip is moved to a positiony to be severed 4from the strip by a movable die blade 34 extending crosswise of the strip and fixed upon the upper end of a lever 35 pivoted to the pedestal or forward end of the table with the opposite end of the lever having a lateral eXtension 36 carrying a roller engaging with the cam formed on the outer side of the cam wheel 33 fixed to the shaft l0. The lever is yieldingly held against the cam by a spring.

The movable die blade cooperates with the stationary die mounted within the table providing a die slot. rlhev forward end of the die blade is provided with a depending tongue beyond the width of the tag strip which is always engaged with the die slot for maintaining the alignment and registration of the movable die with the stationary die. The swinging motion ofthe movable die produces a shear action across the tag strip.

in Figure 13 the movable cutter is shown in its normal rest position with its cutting edge above the plane of the tag strip but in a position to be engaged by the forward or butt end of the feed finger. At the time the foremost tag is severed from the strip a second or succeeding tag is in position over a` printing platen 38 recessed within the table and beneath the type carrying or printing head 39 ofthe printing mechanism. The rinting head is formed on the end of an over anging portion of a lever 40 suitably fulcrumed upon a forwardly extending bracket arm of the pedestal with the lower end ofthe lever engaging into a peripheral cam groovel d1 ofy the cam wheel 33. The printing'head is arranged to receive and sustain a removableV type base lf2. rThe cam wheel for actuating the printing mechanism has its cam groove of a pattern to actuate the printing head twice in relatively varying degrees in each revolution ofthe cam wheel. The printing head is first moved downwardly for an impression stroke to print upon the foremost tag of the stri this operation taking place in advance of t e strip feeding whereupon the printing head is again brought down but to a lesser degree to impress upon an inking pad 43 mounted ina forward position upon the carriage and after the pad has been moved with the carriage to the forward end of its stroke r bringing the pad beneath the the carriage at the forward en dwells for a slightl period so that the pad is printing head,

of the stroke:

at rest when engaged by the type of the printv wise rubbing action between the pad and type face.` The. relative timing of the various parts for each operating cycle is so arran ed that the lforemost tag of the'l strip is rst printed upon and then advanced or moved to aI position to sever it from the strip and issue the same from the machine.

The machine is primarily adapted for handling price tags possessing a staple for attaching the tag to the goodsto be ticketed, the staple having a pair of prongs extending from the underside of the tag which are pressed through the goods and then clenched over against the'underside of the goods. The tags respectively, with the advance of the strip, as they leave the printing or price marking station, move into engagement with a gripper to hold the tag after it has been severed from the strip in an outstanding or projected position for dispensing or deliveryover a clenching block for attaching the tag to the goods. In the present instance, the gripper' engages the top edge of the ta and reciprocates transversely to the strip or 1n a direction at right angles to that of which it was delivered to the gripper for moving the ticket outward from the table in an appropriate position with the prongs over the' clenching mechanism. The clenching mechanism moves upwardly to force the goods over the prongs of the staple and clench the prongs against the underside of the 'rethe goods. The gripper holds and sustains the tag in a horizontally projected position vbeing fixed to the pedestal 22.

The lower side of the gripper block 44: is grooved or channeled for receivin and recessing a. swinging spring-presse gripper I in the side walls 49 ofthe channel. The

'aw 47 swinging within the channel of the lock and pivoted by a pin 48 engaging withgl'lP' per block is shown as of sectional form for convenience in manufacture.

The jaw is normally depressed by a sprin 50 (see Figure 15) against a pair of space stationary jaws or tongues 51-51 extendin from the forward end of the gripper bloc and integral with the ,walls forming the channel. The swinging jaw 47, centrally, is provided with a guide tongue 52 and copperates with the stationary jaws for rcceivmg the tag as it" is advanced by tle movement of the strip. The tongues at their approach side are bevelled or inclined to guide the tag upon the upper side of the tongues as the tag is being moved into position within the gripper and between the movable and stationary jaws. The underside of the movable jaw for its full width is provided with a roove 53 as a clearance for the head or cross ar of the staple on the face side of the tag. The jaws grasp the marginal edge of the tag between the line of staple and edge of the tag, thus clearing the staple so that the prongs of the staple do not interfere with the feed of the tag between the jaws of the gripper and are positionedadjacent the ends of a swinging .guard beneath the ljaws of the gripper and' sustain the` prongs against displacement during the process of applying the goods to the sta le.

he guard constitutes a swinging arm 54 lying within the channel of the gripper block and pivoted thereto at a point rearward of thclswinging jaw as shown in Figure 15. The

arm thus is spring-pressed downwardly so that its forward end is directed about midway of the length of the prongs and the-forward end of the arm is forked so as to :traddle the guide tongue 52 depending from the movable jaw and allow the guard arm to be swung into alignment with the lower jaws 51 under the pressure of the clinching mechamsm.

The guide tongue on the movable "aw, the stationary jaws and the forward en s of the guard arm are approximately of the same thickness and correspond to the gauge of the wire of the staple so as not to form any obstruction 'rvinterfere with the proper application of the tag to the goods and the degree of clinching of the prongs.

' The gripper is disposed immediately adjacent the cutter so that no additional feed motion is required to fully position the tag within the grlpper. The tag is firmly gripped between the jaws preferably during the severing operation so as to be firmly held `by the gripper when the tag is severed from the strip. Pres-tureL is applied uponlthe movable jaw by lever devices connecting with the gri per block for reciprocating the same.

) lever 54 is pivoted within the forward end of the gripper block 44 and has its lower end inclined to clear the movable `j aw 47 Awhen the lever is swung to'a retracted position, during the period when the tag is fed between the jaws or whenthe gripper mechj anism is in an idle position.

' In the active position of the lever 54,

upper side of the movable jaw or depressing the jaw to bring a clampin pressure u on.

the tag between the jaws. T e u per en of the lever 54'?L is'forked and pivotally connects with a sectional connecting 'link 55. The sections of the link 55 are telescopically joined with a s ring l56 interposed .between the/sections renc ering the link yieldingly extensible to accommodate for variations in tag thickness and for any overthrow motion in the lever mechanism for reciprocating the gripper.

lThe opposite end of the sectional connecting link is pivotally connected to the upper end of a lever 57 swin ing upon a fulcrum 58 fixed into the side ofg the pedestal and extended through the bracket 47 supporting the gripper or dispensing mechanism. Thelever 57 is providedwith a laterally extended pin 59 extending into a cam roove 60 of a cam wheel 37 Fixed upon the saft 10 of the portion of the shaft extending through and journalled in the pedestal.

In the forward stroke of the lever mechanism, the lever 54l is initially moved to compress the jaws, impinging a tag therebetween, whereupon through the continued motion of the lever mechanism, motion 'is imparted tol the gripper block to move the same forward, bringing the-sustained tag1 over the clinching mechanlsm for securing t e tag to the goods.

A rcturn stroke of the lever mechanism releases the gripping pressure of the jaws, the lever 54a is swung to a retracted position by engaging with the gripper block which limits its motion and stabilizes the connection between the connecting link and lever so that .the jaws are released and remain released until the parts are againI moved forward.

The staple clinching vmechanism is of a commercial type analogous to that disclosed in Letters Patent No. 1,171,729, dated February 15, 1916, and comprises a tubular plunger 62 slidably mounted within a bore of a forward extension of the rear bracket 47. The

lower end of the plunger 62 isnotched to re' ceive the forward end of an actuating lever 63 as shownin Figure 12, the lever 63 swinging upon a fulcrum'64 supported within the pedestal and bracket.

The rear end of the lever is provided with a roller 65 engaging upon the periphery of the cam wheel 33, the cam wheel upon its periphery being provided with a radial cam 66 appropriately for liftingthe lunger 62.

- 75 suiiiciently to apply the necessary upwai" `vstem bearing against a spring `69housed and supported within the plunger, Thest'em of Ay clenching ahead 67 yiel ingly connects with the plunger 62 by means of'a Cstem 68 integral with the'head and` telescopcally en gaged into the plunger, the lower end of the the plunger headis locked agai st rotative motion by a key 70 fixed to the plungenand extending into a notch 7 (see Figure 10) of the stem. 6 A

.The head is slotted diametrically and p'rovided with a pair of oppositely disposed ivotally mounted within the slot of the head and fulcruined to'- swing upwardly toward each other, each to bend or clench a staple prong against the goods as shown in Figure 11.'-

The clenching dogs are.` actuated shaped plate 73 slidably mounted within the slot of the head beneath the dogs and engaged by a collar 7 4 slidable upon the stem 68. The collar in turn is engaged by aspring'75 inter'ose'd between the collar and the upper end? of the plunger 62.

In an' upward movement of the pluri er with thegoods to be ticketed spotted over t e head, thel tag held bythe gripper with its staple prongs extending in a. perpendicular position over the clenchingdogs which are in an open or receded position belowT the-plane' ofthe head, the'material'is-pushed over the prongs until the upward movement ofthe ead is .arrested by contact ith the projectin ends of th ,movablegr pper jaw held loc ed by ,the lever. The plunger continuesI its upward motion, compressing the spring pressure against the collar and T plate, fore-"-y ing the clenching dogs upward tp clenchthe' staple prongs.

The upper surfaces of the clenching-fdogs are curved for directing the points ofthe prongs intothe goods. f The yielding connfefetion between the stempf the ead and'pliinger compensates for the additional movement of the plunger after the head is arrested "andn maintains the head compressibly againstthe goods and tag while the staples are being clenched. i j The machine normally is at rest ,withV ticket feeding carriage at its foremost poeltion theinking pad :beneath the printinghea the printing head in a retracted on lifted position clear of the inkingpa'dfan tion ofthe driving shaft. Upon tripping "the clutch the dispensing device is moved, vfoi'.-

The carriage'follows moving forward and comes to rest allowing the printing head to descend for pressin its type upon the pad and again retreat be 4ore the clutch is automatically tripped at tl'ie end 0f the cycle to cut off the power. The machinel is capablefof operating atl high speeds. The operation is momentary from the timel the o erator depresses the clutch control for app ying a tag.
