I App licatlon filed October 27,1924. Serial No. 745,568.

My pending application No. 535,311 filed February 9, 1922, illustrates an embossing machine where'n there is a longitudinally reciprocable die-carrier having male and fe-' male dies, a keyboard for moving and positioning the die carrier and mechanism operating automatically, consequent u on the die carrier coming to pos'tion, to p unge positioned dies toward each other, to emboss an interposed strip of metal.

The present invention relates to a very sim le mechanism adapted to be coupled with $110 an embossing machine for printing the characters on a continuous strip of paper as they are embossed on the strip of metal, the printed characters being readily visibleto the operator. The printed strip thus forms a visible indication to the operator as to whether the proper keys have been struck.

By a very simple arrangement of a' scale adjacent the paper strip I am able to indicate to the operator just where he should cut ofi the embossed strip for the proper length of line. provide means for automatically placing a distinct] ve mark on the paper strip 1 lines on the paper strip are visually sepa-f rated though they are all in a continuous row.

The present invention includes the printing" and indicating mechanism. above outlined. It also includes a shift mechanism cooperating with the printing mechanism, enabling the selection of a desired row of 1 on the wheel which affects the printing. It also includes simple devices for effecting the inking of the printing wheel, and for accu- -vent vibration thereof and insure anaccurate imprint. Y I

The above and other features of the Inven- U 4} tion will be apparent from the following 2 5 detailed 'descript'on of a preferred embodiment illustrated in the drawings.

will first describe the embossing machine shown, it being understood that a complete keyboard is provided, having the usual 81-. phabetical, numerical and punctuation characters, and mechanism controlled by the actuation of any-key for correspondingly positioning thedie carrier,

Figs. 1, 2, 3and 8 show the'd'ie -carrier,

whic, is a reciprocable block 10 having a" longitudinal open ng-or channel 11 in its uppenportion. This block is ided to reciprocate on rods 12 and 13. ying within the channel 11 is a pair of frame rails 20 and 21. The die-carrier has a pair "of rolls 15 and 16 bearing'on opposite sides of these rails. The lower end of the rail 21 is provided with a longitudinal rib 22 forming a support and -guide for the channel-shaped metal strip A being embossed. This strip is period'callyprog'ressed from left to right by a pair of rolls 25 and 26 actuated by a ratchet wheel 27 and pawl 28 connected with t the embossed mechanism as hereinafter de- The die-carrier carries a row of male die blocks and a corresponding row of female die blocks 31. Such locks face each other and are ada ted to be plunged toward each other to em oss th'e interposed strip. As shown each. die block carries in a vertical row, three related faces, as for instance, lower face, upper face and numerals or punctuation marks. The dies are normally retained in their inactive position by springs 33 carried by suitable brackets 32 rising from the dc. carrier. Suitable shift mechanism, hereinafter described, raises the carrier from the normal position shown in Flg. 1 to bring either .of the other die faces into the horizontal plane on the metal strip A.

The mechanism illustrated for moving the die carrier comprises a pair of solenoids 35, (Fig. 2) operating on a common core bar 36 connected by a link 37 with a pivoted arm 38, the pivot being beyond the illustration in Fig. 2. The. other or forward end of this lever 38 is bifurcated, as at 39, and embraces a block 34- ivoted to the underside of the die carrier. uitable means, not shown, are provided for enabling the depression of any key on the right-hand half. of the keyboard to energize the left-hand solenoid 35,

thereby drawing the die carrier toward the left to bring into central position the corresponding-pair of dies in the right-hand half of the die carrier. Similar action of any key on the left-hand half of the key-board results inthe die carrier movement toward the right to position a corresponding pair of dies in the left-hand half of the .die carrier.-

Immediately upon the die carrier coming to central position, suitable clutch mechanism, not shown, is automatically thrown into action causing a single rotation of the shaft 50 (Fig. 1). This shaft carries a air of double crowned cams 51 and 52 w ich operate levers 53 and 54,. which carr at their upperends adjustable studs 55 w ich serve to ush toward each other the reciprocable plungers 56. These plungers thus engage the pair of dies which are in central position and force them toward each other to emboss the interposed strip.

Some of the keys of the keyboard areindicated at 40, in Fig. 3. These keys have levers41 extending rearwardly and intermcdiately pivoted, as at 42. The rear ends of the key levers stand alongside of each other, as shown in Fig. 8, and are guided by vertical slots in a transverse frame member 14. The die carrier has a suitable latch mechanism adapted to coact with the raised rear end of any key lever tolock the carrier with the dies corresponding to such key in active position. The latch mechanism shown in Figs. 3 and 8 comprises a pair of vertical plungers 45 having beveled lower ends 46, and suitable L-shaped abutments 47 constrained by springs 48.

When the die head is released by the depression of a key, the solenoid which is energized by such depression causes the head to move toward the rear end of that key lever until stopped by the abutment 47 engaging such key lever. Just before this takes place, the plunger 45 will be cammed upwardly by its beveled bottom engaging the key lever and will then'dro down on the far side of the le cr, thereby locking the die head to the key lever. Fig. 8 shows one of the plungers as it is traveling over the raised key lever end 44 and just before the die head comes to a stop.

The abutments 47 and plungers 45 are mounted in a suitable housing 17 which travels laterally with the die head, and is guided by a roller 18 in a channel in a frame member 19. The die head is vertically slidable with reference to the housing to select different ,faces on the die blocks as hereinafter explained, but for lateral movement the two operate as a unit.

Resting on the upper ends of the plungers 45 is a pivoted ball 49 which is connected by a link 57'with a bell crank 58 connected to a rod 59 which controls the clutch mechanism above mentioned. Accordingly, just as the die head is comingto position, the raising of the corresponding plunger 45 causes a withdrawal of the rod 59 releasing the clutch to effect the single rotation of the shaft 50 to cause the embossingvaction of the dies as already described.

'To enable an embossed line to be readily cut off from the unembossed portion of the strip, I provide in the die head, a pair of shearing dies 23 and 24. These dies are preferably male and female and may have the form shown, in plan, on dotted lines in Fig. 2 and in elevation in full lines in Fig. 3. provide in the keyboard a special key 43 which operates to position these dies in alignment with the die-operating plungers. It is the rear. end of the key lever 44 on this key which is shown in elevated position in Fig. 8. When the die carrier is stopped by such key, the shearing dies 23 and 24 are in line with the reciprocable plungers '56. The operation of these dies therefore is similar to that of character dies except that the strip is sheared in two instead of embossed. While the character dies preferably have multiple faces, I prefer to provide only a single pair of shearing dies located in the row of lowercase characters.

The printing mechanism operates concurrently with the embosser, printing a character on a paper tape whenever a character 'key isstruck, and printing a suitable mark rows of faces on the die blocks,three rows being shown. This wheel" is preferably cored or drilled for lightness as shown at 61 in Figs. 2 and .6, and is freely journaled on a stationary vertical stud 62, shown as carried by a portion of the frame 63. Below the wheel proper is a reduced cylindrical extension 65 secured to the lower end of which is a gear 66. This gear meshes with arack 67 secured to the top of the die carrier 10. In Figs. 2 and 6 an arm 70 is shown pivotdat 71. This arm carries adjacent its end a roller 72 riding on the upper face of the rack, and carries also a roller 73 ridin on the under face 'of the type wheel. s pecifically this roller 73' bears against a washer 75 surrounding the" type wheel shank as shown in Fig. 6. i

It will be seen from the construction described that when the die carrier is shifted longitudinally in either direction, the wheel is given a partial rotation correspondingly. WVhen thedie carrier is shifted vertically to change the ,case of the active (lies, the wheel is correspondingly shifted by reason of thefloating rollers described. Accordingly, the proper character in the row of type, as well as the proper row, is brought into printing position, in corre spondence with the dies which are brought into the active position.

Onopposite sides of the type wheel, I

i provide a pair of inked rollers, which are preferably of absorbent material such 'as felt and once inked will.carry such ink for ,a suitable length of time. As shown in Fig.

6, the felt is in the form of a thick sleeve 80 mounted on a tubular core 81 on a head 82. -The felt is compressed by a disc-like nut 83 screwed onto the upper end of the tubular core. This compound spool is -rotatable on a stud 85 carried by the frame J member 63. The construction of the spool described enables the felt to be replaced whenever desired by thesimple removal of the disc nut 83'. Moreover by screwing down this nut ,onto the felt, the latter iscompressed and forced radially outward to compensate for wear caused by the printin characters 64. To cause the inking spools to shift vertically with the printing wheel, I make the heads 82 on the spools of greater diameter than the spools and extend them into a peripheral groove 88 in the printing wheel.

As shown .this groove is provided by the.

washer 75 and a rabbitt in the bottom of the wheel proper. By this arrangement, any drag on the wheel across the felt and the consequent foul of the type,. is avoided.

The tape of paper to be printed, indicated at B in Figs. 1, 2, 4 and 9- is carried on a reel 90, (Fig. 2) rotatablymounted on a stationary stud 91. The paper tape lead from this reel across the guide roller 93 and thence across a portion of the face of the platen roller 95 and thence behind a guide pin 96 and into a longitudinal guideway 97. This guide comprises a strip of metal with its edges flanged forwardly and downwardly, whereby an undercut passageway is. provided to guide the tape and still expose it," except at its edges. This guideway is somewhat longer than the longest line intended to be embossed by the machine.

At the left-hand end of the guideway 97 is a roller 100 around which the paper tape extends. Thetape thence passes behind the guideway and into the grip of a suitable feed'mechanism. As shown, I accomplish the feed very simply by providing a roller 102 which bears against the platen roller 95 and is geared therewith by gears 103 and 104;. The paper tape is gripped between these rolls and periodically fed bypartial rotationsgiven to the platen roller described.

The platen roller 95 and the guide rollcrs 93, 100 and 102'and the longitudinal guide 97 are all mounted on a rocking frame which is pivoted at some suitable point as 111 and 112to apart of the stationary frame. This rocking frame extends below the vpivot 111 in the form of an arm 113 which is connected b arm 115 secured to t e hub of the emboss ing lever 53 on the shaft 119. From this it follows that when this embossed lever swings, to plunge forward the corresponding die to effect embossing, the rocking frame 110 is likewise swung forward (but to a less distance) to bring the paper tapeinto engagement with the positioned printing character 64- on the type wheel. Suitable eccentric adjustment 118 between the arm 113 and link 114 enables this movement of the paper tape against the type wheel to be adjusted to cause the desired depth of impression.

The roller 93 and the roller 100, each is provided with a bottom flange for supporting the tape of paper. 'Roller 102 preferalink 114 with an ably has both top and bottom flanges to 'roller 102; This latter roller is mounted on an arm pivoted at 126 and drawn towardthe platen roller by a spring 127. The other end of this spring is anchored to an arm 128 which carries the'idler roller 93.

Au eccentric 129 mounted on the arm 128 and provided with a screw-driver slot by which it may be turned, furnishes an adjustable stop for the arm 28 whereby the idler roller 93 may be held in adjusted position with reference to theplaten roller. This idler roller does not contact with the platen roller but by varying its proximit thereto, the extent of the periphery of tiie platen roller which the paper tape engages is varied and thus an adjustable tension is provided. This enables varied grades of paper to be kepttaut .in the guide.97. The paper tape may be initially positione by rotating the platen. roller 95 and it has a geared roller 102. To enable this to be readily efl'ected I pin the platen roller 95 I to the pin 105 which is freely journaled in in Figs. 4 and 5.

' arm 110 directly over the strip frame member 110 and the overhanging bracket portion 117 thereof, and I provide a knurled knob 107 in the upper end of the pin. This enables the platen roller to be turned mainly in the direction to feed the paper tape. If it be desired to backspace the paper tape, this isreadiIy effected by the same means when the pawl 121 is swung away from the wheel 120. A suitable peg 124 projecting upwardly from this pawl enables it to be conveniently shoved aside by the operators finger.

The types 64 on the printing wheel are preferably embossed on metal strips extending about the periphery of the wheel and anchored thereto in a notch in the wheel as indicated at 130 in Fig. 2 at one end and at the other by a pin 135. Associated with one of these printing strips is a member for printing a vertical line on the strip of paper. I have shown this member as a thin plate 132, secured to the type wheel by one of the screws 133 securing the lower case or top type strip 64. This plate 132 isso positioned on the type wheel that it comes into coaction with the platen whenever the die carrier is positioned to bring'the shearing dies thereof into active position, and when such shearing dies are operated to cut off the finished portion of the embossed strip, and the platen frame is thus automatically swung forward.

this prinfing member 132 prints a vertical line on the'paper tape, as indicated at I) This accordingly marks the end of the line.

It will be seen that while my machine prints the lines successively ona cont1nu-,

ous tape of paper, the length of each line is indicated by means of the imprinted vertical line b. This same arrangement enables the operator togage the length of the embossed and sheared lines. To this end I provide ascale 140 carried by the rocking guideway 97. This scale is guided into equal spaces corresponding to the width of the characters. Slidable longitudinally of the scale is a suitable pointer, preferably a spring metal clip 143, U-shaped as shown in Fig. 7, havin bowed portions embracing the upper an lower edges of the scale and having a depending prong 144 directly adjacent to the upper edge of the paper strip.

Before the embosslng operation, the o erator sets the pointer at a distance from tiie right-hand end of the scale 140 corresponding to the length of the line to be embossed. Then, when the left-hand portion of the line on the tapereaches the pointer, the operator knows that his embossed line is of the desired length. shearing key to cut off the embossed line, and this results in printing the line indicator 1) on the strip, marking the end of that line. This tape may also be utilized, if de sired, as a proof or record of the lines embossed.

To position accurately the die carrier and the printing wheel and lock them during the embossing and printing operation, I provide the lockin device shown in Figs. 2 and 3, consisting o a rack 150 on the die carrier having beveled teeth and a plunger 152 carried by the frame and having at its forward end corresponding teeth 151. This plunger is freed from the die carrier during the positioning thereof, being held back by lugs 153 eration as soon as the lunger is released on the forward stroke 0 the embossing lever 54. Accordingly, before the embossing or printing takes place, the beveled teeth on the plunger 152 come into coaction with the eveled teeth 150, accurately centering and locking the die carrier and printing wheel.

The cross head 155, is adjusted on the plunger 152 by reason of the nut 158 and the clamping screw 159, Figs. 1 and 2. The active end of the plunger 152 is wide enough to engage the rack 150 on the die carrier irrespective of the vertical latter, as controlled by the s about to be described.

Referring to Figs. 1 and 2, the bar 12 on which the die carrier slides, is mounted at ift mechanism 'its ends in vertical shiftable blocks 160.

keys and cooperates with the latch mechanism which I will now describe.

As shown in Figs. 1 and 10 to 13 inclusive, slidably mounted in the forward end of the Thereupon, he operates theposition of the lever 164 is the shank 171 of a key 170. At

the rear of this is 'a key 172 which-is rigidlystop pin 174., are adapted to engage a stationary abutment 178 carried by the frame. .The parts described are normally in the position shown in Fig. 1,-which corresponds to the upper row of characters in the die head and the printing wheel.' Now, if the operator places his finger'on the key 170 and presses it down until its lower end strikes against theabutment 178, he will thereby lower the shift lever one step, which raises the die carrier and type wheel to bring the second row of characters into ,action. If, on the other hand, the operator places a finger on the key 172 and forces the shift p lever down to the limit, this limit will be provided by the pin 174 striking the abut ment 178, the shank 171 sliding relatively upward in the shift lever. This lowers the forward end of the shift lever two steps, bringing the lowermost row of characters on the die carrier and the printing wheel into action.

To hold the shift lever in either of its shifted positions, I provide a latch 180 having a pair of teeth 181 and 182 adapted to engage a lip 183 on the shift lever. A

spring 185 anchored to the latch tends to. swing it toward the lip 183. When the key 170 is depressed, as described, the tooth 181 accordingly comes over the lip and holds the parts in their intermediate position (shown in Fig. 11) when the key 172 is depressed, the tooth 182 engages the lip and holds the die head and printing wheel in their uppermost position.

To return the'die head and printing wheel to normal or lowercase position after each embossing operation, I provide the following described 'mechanism (which, however, may be thrown out of action to emboss any of the unusual cases for more than one charg acter) namely, I mount on the shaft 195 of the embossing lever 54, an arm of lever 190 which is connected by a link 191 with a rocking arm 192 to which is pivotally connected, a bar 193, the free end of which normally rests on apin 194 on the side of a latch 180. The bar 193 carries a pin 196 overhanging the top of the lip 183. When one of the keys 170 or 172 is depressed, the'latch 180 is cammed forwardly bythe lip 183 This carries the pin 194 from under the main portion of the bar 193 so that bar follows downwardly after the depression of the shift lever and thus its shoulder stands in front of the pin 194. Now, following the embossing oper-' 190 shoves forwardly the bar 193 and thus swings the latch bar 189 out of engagement with the lip 183 and thus'the shift lever is free and the die head and type wheel drop by gravity 'to normal or lower caseposition. As the forward end of the shift lever rises the pin 196 causes the bar 193 to be restored to normal position.

In case it is desired to cause the mechan ism to remain in its shifted position for more than a single character at a time, it is only necessary to swing backwardly the bar 193 on its pivot into the osition shown in broken lines at 193 in Fig. 11. Then the throw-out mechanism described is idle and the die head and'printing wheel remain in whatever shifted position has been given the shift key 170 or 172.

The upper end of the arm 190 is connected by a link'200 Fig. 2 (omitted in Fig. 1) with the rocking arm 201 carrying the awl 28 coacting with thestrip feed ratchet 27 heretofore described. This results in the metal strip A being fed a distance corresponding to the width of each character consequent upon the return of idle position of the embossing lever 54:. l
