This invention relates tomarking machines and isf illustrated as embodied in the type of Y machinein whichraheated. die isused to transfer a marking medium to the work.

In machines ofV this type, which p times called embossing machines, the pigment or metallic leaf used as a marking medium is .supplied in strip form `upon a carrier ribbon of paper. The marking medium is thenv applied to the workby pressingl against the -reverse sideof the carrier strip vwith a heated die. In the operation of such machines considerable pressure is required, `whichshould be applied evenly lfor a- Vsubstantial interval. f Accordingly, an object of the invent-ion is .to provide an improved machine of, thistype by means of which heavy pressure maybe ap lplied to the heateddiein a mannercalculated -to assure an even impression upon thework while insuring quiet, rapidoperation of the machinef' V f Y" l.i

To this end an importantfeature-of the Y inventionrelates tothe mounting ofthe Vmovable impression vmenliber which latter',` in the preferred formlof vthe device, is a heated die. As illustrated a gooseneck-shaped, .die-

`carrying arm is slidably mounted in grooves provided atthe forward vpart of thel frame and retained in position by a cover plate which carries the cooperating impression member, here awork-supporting table.` The illustrated die-carryingfarmy is made up ofl laterally spaced members'y to lallow 'the pasbrought, forward into `ali'nement with the inipression members .so that pressure'mayfbe deliveredto said arm in alinement with the y required pressureby power supplied from. `a

' cam shaft therebyinsuring even heavy pres# sure and quiet, positive operation,4

y In accordance withanother feature ofthe invention, a work-supporting table isfillustrated as mounted in the cover `plate which] serves as a retainingmember for thesliding die-carrying -arm. To insure even impres- *sionsv in spite of inequalities in the thickness of the work, the illustrated wolkfsupporting tableJ is providedwith a spherical portion re-l ceived in a similarly-shaped socket which in turn, 4is f resiliently supported @in ,the above# are some# Y drawings inwhich, two impression members, as by means-.ofay togglek which is straightened to deliver thev nfientioned cover` plate. Y Suitable imeansilsuch `as a. spring is vpreferably,provided for returningthe table vtonormal .position case it be-l i comes displaced in the. operation.ofthefmachine." y Y Y. in' 'machines of this typefrhe handling Of the Vstrip carrying the marking medium is made diicult by the factfthatthe pigment yor metallic leaf may be separated fromjthe carrier strip in casev it becomes unduly heatedl remainingtoo long in proximity to the heated' die. There is, furthermore, a tendencyfor the carrier strip lto stick either tothe Work or to the heated d'ieor to both,.and it has'been found-necessary toprovide mechanism toin-Y sure; the separationof the carrier strip from the workand the heateddie after the comvenient handlingof the strip -requires'laz takeup mechanism and each new'strip must be threaded throughthis mechanism. f

In view of theforegoing, other important features of. ther invention relate to improyed" mechanism for supplying and taking ,up ythe istrip Carrying the marking medium and to 7o pletion of an impression. SA'gain; the con'- improved devicesfor guidingzthis stripl arranged to hold. it awayfromthe heated die when the machineis in its stop position, while l Y still allowing it to come into"` contact with the die when making an impression.. kAnother novel device facilitates. the separationof the work and the strip afterthe impression Ahas been made. "sage of a. strip'of marking medium from front 'to rear kand the lower Lend` yfof the arm is will be bestunderstood vfrom aconsideration These other featuresl of the invention-V 4 ofthev following specification and claims taken -in connection withV the accompanying with partsfbroken away'and'parts injsection;

s .Fig 2 is a side elevation' of themachine with parts in section; and

ing itsrelation to theimpressionmembers. v .Thcvframe 'of the machine 1s made up 'of a'f basefl() and spaced side 'portionslQ and 14 whichr are' connected near-the rear; of the machine by cross.portionssindicated at116 and :18 in 2. Adriveshaft 2O is ournaled in the 'sidcportions lof theframe 'and maybe pro-` vided with a suitable` pulley y, 22 at oneje'ngd and a pinion 24 at the other-end arranged to side mesh with an internal gear 26 in a wheel 28 mounted at the end of a cam shaft 30 which is also journaled in the side members of the frame. cated at 32 inyFig. 1, which is controlled by a treadle rod 33, may be interposed between the wheel 28 and the cam shaft 30 and `a cover plate 34 provided so that the inion 24 and the interna-l gear 26 are completely enclosed.

A movable impression member is carried at the u er forward end of a gooseneck-sha ed sli'dag e member 40 on the overhanging or- Ward arm of which a die-carrying block 42 'is provided. In this die-carrying member,

'up oflaterally spaced members 52 (Fig. 1)

and 54 which are provided with ribs, one of which is shown at 56 in Fig. 1, and these ribs are received in suitable grooves 58 (Fig. 3) provided in the forward part oi the frame of the machine. A coverl plate 60` attached by screws to the forward edges of the Y ortions 12 and 14 serves to retain the siding die carrier in position in the frame and with the grooves 58 guides the slidable member 40 Vfor straight linemovement. At the same time this cover plate 60 renders the frame more rigid by joining togetherthe spaced 'side portions thereof. As may be seen from Fig. 2, the latyeral members 52 and`54 of the gooseneck die carrier are connected by an integral web 62 and it will be observed from Fig. 2 that the lower ends 64 of the lateral members lie directly underneath and in alinement with the die 44 and the opposed impression mem- 'ber to be later described. This makes it possible to apply pressure from `a point beneath theoperating mechanism of the ma-V chine directly in line with the moving elepivoted to the lower ends 6 4 of the gooseneck member at 7 2. `The force required to straiv'hten thertoggle is applied through a 'linliji connected at one end to the toggle at its knuckle and at the other end the link is A suitable clutch, such as is indi-` pivoted at 76 in a recess (Fig. 2) in one arm of a forked lever 78 pivotally mounted upon a ro'd` 80 extending across the base :of the machine. This forked arm 78 surroundsa cam 82 in cam. shaft-30, which is designedin a manner Well `understood in the art so that it continually is in contact with `both sidesV of the fork. The cam is designed to hold the die in engagement with the Work through a half revolution of the cam shaft 30. It 1s then arrangedv to lift-the die quickly, after pressure has been applied, por. to depress the die quickly at thelcommencement of the opera tion, each of these" steps taking place ina quarter revolutionof the shaft.` This ar rangement also assists in the quiet operation of the machine and the application ofV suilicient force with a minimum expenditure of Y power.

A Work-supportin table 90, which constitutesfthe lower and xed impression member, is carried .by the cover plate 60 and is provided with a beveled `forward edge which assists in the insertion ofthe worktbetween the table and a stripV er guard 92 comprising a U-shaped piece oipwire mounted on studs adj ustably fixed on said table.' T hus the work is held back when the die rises and sticking of the carrier stri thereto is avoided. The table isfals'o provided with a spherical pro'- jection 94 on its under side, which is received in and supported by the complementally shaped annual upper edge ofa socket member 96 slidably mounted ina suitable guideway; 98 formed in the cover plate 60. Astud 100 passes through the bottom'of 'the socket m1e1nber`96 and through an adjustable plug 102 in the bottom ofthe guideway 98 where rit is held by means of nuts 104. Interposed between the bottom of the socket member 96 and the plug 102 is a relatively stili spring 106 which providesa resilient support lor the table 90, and it will be observed that the tension of this spring maybe adjusted by turning the plug102.` A light spring 108 connected to theupper end ofthe stud is joined at its upper end to a lug V110 depending fromthelower side of the spherical member 94. Thisspring' serves toreturn the `table 90 `to its normally level position.` when it is angularly displaced by reason of `un Vevenness in the die 44 or irregularities in lthe i work. To prevent rotation or the table 90 in ahorizontal plane, pins 112 extend upwardly from the cover plate 60 and are received loosely in a transverse recess in the lower side of the table 90. The table 90 isthere! fore retained normally with its beveled edge at the front of the machine but is not vented from being self-adjusting, as required Y by the character of the work, to insure an In Vaddition to the mechanism thus far described for actuating theimpression members of the machine, mechanism is provided 'for delivering the `rriarking medium to` a -point between the-.impression members and for feeding or taking up the used part of the carrier strip. To this end a supply cas ing 120 provided with a hinged lcover 122,

which is held in closed position by aflatch 123, is mounted upon the forward upperend of the gooseneckmember40 and is provided with a transverse `horizontalspindle 124 upl on'which-maybe'mounted a supply roll y1,26

Y Ushapedmember carried in rotatable studs ro N - tion in suitable sockets in the supply .casing in the side of the casing 120 andlield in 'upright position in Contact with the uncoated side of the strip upon the roll 126 by a spring 140. Thestri-pthen passes down through a narrow part of the casing 120 wherev it 'is kept in the desiredposition transversely of the machine by lateral guides 142 which are ad justably mountedina` slot-,144 in the cover v122 of the supply casing and are retained in adjusted position by means of nuts 146. After' leaving the lateral guides 142, the strip 136passes over a horizontal guide bar 150 formingv the base of a vUshaped member whose upstanding arms are received in rods 152 which are adjustably retained in posi- 120. The strip then passes-under the die 44 Ythrough a passageway formed by the spaced Vmembers 52 and 54 to feeding mechanism and in the stop position of the machine is held vont ofcontact w-ith the lheated die by a guide roller 154 carried onthe outer end ofarms 156 mounted in a removable frame158 supporting thetake-up or feeding mechanism.

The vlink is connected at its other end to a block 186 ,adjustably Vmounted in the slot of an oscillating varm 188 secured to a horizontal stud 190 to' theinner end of `'which is secured a vforked operating lever 192. 5 This lever surrounds and is always in contact withfan eccentric 194 mounted on the camshaft 30.' Adjustment of theblock 186 in the slot of the'arm 188 iseffected by means ofvasc'rew196 whichV may beturned by a head 198. VBy means of the arrangement just described a .constantV anglel of Aoscillation is imparted to the arm 188'but the extent of the'rnovement imparted j to the strip 186'may be adjusted through a considerable range by adjusting the heady 198 and this range may be increased by changing the connection ofthe link 180 to the depending -arm 178 of the rack 174. Such anarrangement renders itpossible tomove the strip along step by step'just as little or just as muchas may e necessary so that a fresh portion of the strip is always Vpresented beneath the heatedV die 44"without mechanism the strip is moved along just as By the timing of the the die descends so that. there is .practically nochance for the spoiling ofthe portion ofv the strip to be used by reason of.` heat from theidie 44 in case the machine has stood with- 5 out being operated kfor several minutes. Y To facilitate the removalof a partly yused stripl of marking medium, means are provided including a finger piece 200 by means of which the feed rolls may beseparated if desired, as described in the above-mentioned Letters Patent. i

" ln using the machine a roll of the desired marking medium is placed on the spindle 124 and the strip is drawn over the take-up member'138 and'passed between the guides 142 fbeneath the guide 150 and through the-pasq sagewnayin themember 40, thence under the Y roll 154'tothefeed rolls.v Havingbeen threaded through the feed rolls it is ,secured to thereceiving roll mounted on the stud 172 where the used portionvof the strip Vwill be rewound'for convenient handling. `Agdie` 44 i y of the desiredcharacter'is clamped inthe diecarrying vblock 42 and theV paper feeding offthe die inthe manner above described so that the paper strip is moved along just enoughto present afresh portion of 'the strip at each operation of the machine withoutun` 5;1.
