The original paper from which the copy is to a be taken is printed in a conventional manner on -a tabulatontypewriter or other suitable medium and is backed with" suitable carbon paper while being printed. The original may take the form of single sheets, fainfold' or continuous roll- The transfer is accomplished by interposing-a ribbon or similar medium moistened with solvent above the area to be transferred and then applying pressure on the ribbon to bring the ribbon, the

' original and theledger sheet or receiving paper together. The solvent dissolves a portion of the carbon from the original and deposits'it on the ledger'sheetm M i m i i The machine includes a table or plate 2|, (Fi

'1) supported between side frames 22 and 23. Upon this table is placed the ledger sheet to receive the impression. The frames 22 and 23 are rigidly joinedby a lowerpressureI-bar 24. (Fig. 2)

bars 25=and 26 and a motor support plate 21. 5

A motor 28 (Fig. '3) provided to drive the several mechanisms of the machine, is mounted on the plate 21. .The motor,'thro ugh a; pulley and beltbconnelction 2'9 nd a gear box'30 supported on the plate 21 operates a short shaft 3| sup- 4o ported in brackets 32 and 33 secured' to the plate '21. Aclutch disc 34 (see also Fig. 4) fast on the shaft 3! is provided with notches 35' about its periphery with which notches a clutchpawl 36 ,pivot'all'y carried by a. clutch arm 31 fast ona cam shaft '3l cooperates. The cam shaft 38 is supported ida'bracket 39 secured; to'the plate Q 21 and .in. .the' frame. the shafts 3| and 38 .beingin axlal alignment.

The. arm 31 (Fig. 4) and shaft sajajr'e normally 9 held against rotation by an arm 40 fastfon .a

short shaft l'lpivotally supported by the brackets The arm 40 has a'shoulder 42 which normally lies in the path of the arm 37 and of a tail of the pawl 36 thus holding the a shaft 48 journaled in the frames 22 and 23.

Also fast on the shaft 48 are two release bars .49 one being located near each end of the shaft and being arranged to lie conveniently one on;

each side of the table 2| (see 1)--.

In order to initiate an operation of the machine the operator depresses either of the bars" 49 which movement rocks the shaft 48 and arm counterclockwise thrusting-the link 46 toward the right. At this movement a lever .58. pivotally carried at the right-hand endof the link- 46 and having a notch engaging the stud 43-,

rocks the arm 44, shaft 4| and arm therewith, removing the shoulder '42 from engagement with the arm 31 and the tail of the pawl 36. The pawl, thus freed, is engaged with one of the notches 35 by a spring56. 'The arm 31 and the shaft 38 make one complete counterclockwise rotation. I

A cam 51, the outline of which is indicated in Fig. 4 by dot and 'dash lines for the sake of cleamess, fast on the shaft 38 adjacent the lever has a single notch in its periphery cooperating-with a stud 58 on the lever"58. As

soon as the shaft 38 starts to rotate the cam' "51 rocks the lever 50 clockwise freeing the arms 44 and 48to a spring 59 which immediately restores these arms to their normal positions. Near the end of the rotation the shoulder 42 rocks the pawl 36 out of engagement with the disc 34 and stops thearm 31 and shaft 38. A

spring pressed retaining pawl 68 prevents retrograde movement or rebound of the arm 31.

If the operator has released the bar 49 before the end of the rotation of shaft 38 the parts top of the stud-13am! it will 'berziecessary'for the operator -to release the bar-49%F'permitting a. spring 6| (Fig. 4), having-one end 'attached to an arm 62 fast on the shafti48, torestore "the link toward the. left before another operation may be inltiated.--- v I redeemed; 'f'i li on which a copy is to be made beneath a trans- 80 parent line finder 64 adjust'ably mounted on a 88 located on the table 2| with its left edge be-" '10 1, 2, 3, '7; and 8) secured-to a'pair of spaced j bar supported in a manner to 'be described later. thereon to assistthe operator in the proper positioning of the ledger sheet. The sheet is neath spring pressed ledger clamps 65 (Figs. 1,

2, 3, and 8), there being four clamps 65 mounted 'on the ledger carriage.

The ledger carriage includes'ajbar '66 (Figs.

This finder has parallel "lines scribed of the table 2|. A stop bar 18 is mounted on the bar 66 to locate the edgeof the ledger when it is placed in position on the table. The clamps 65 are slidable vertically in the bars 66 and 18 and are normally urged downwardly to grip the paper 63 by springs 1| secured to the under side of the bar 66. I

After the ledger sheet is in proper position the; operator depresses the releasle' bar 49 whereupon theshaft- 38 rotates. Shortly thereafter a cam 12 (Fig. 8) permits a spring 13 to rock ;clockwise an arm 14 mounted on 'a shaft 15 supported in the bracket 39 (Fig. 3) and the-side frame 23. An arm 16 fast to a shaft 11 (Figs. 3 and: 8) is connectedby a link 18 to the arm 14. Also fasten the shaft 11 is a bell crank 19 whoselink to a bell crank 8| pivoted on a stud projecting from a bracket 9| secured'to the bar 24. A bar 82" supported on the bell-cranks 19 and 8| is normally pressed upwardly against the paper clamps 65 and against the tension of springs 1| by the'cam 12, v

'The clockwise, movement of the arm 14 described above is transmitted by the link 18 to rock the arm 16, shaft 11, bell crank 19 and due to the connection 88 the bell crank, 8| counterclockwise to lower the bar 82. This permits the springs 1| to draw the clamps 65 down gripping the ledger sheet 63 firmly between said clamps and'the carriage bar 66.

- Shortly after the ledger sheet is gripped, in the manner just described, mechanism now to be described isoperated to shift the carriage a distance suiiicient to move the selected line from its positionbeneath the line finder 64 (Fig-6) to a position under a pressure bar 83. This mechanism includes a pair of cams 84 (Fig.7) cooperating with a bell crank 85 pivoted on the shaft 15 and which is connected by a link 86 to an arm 81 fast toa shaft 88supported between the side frames 22 and 23. Another arm 89 also faston the shaft 88 pivotally carries at its-free end a lever 99 having. one arm connected by a link 96 to the rear block 61 of the ledger carriage. A spring 91 presses the other from the arm 89-.

As the shaft, 38- rotates, rocked clockwise. which movement through the link 86, rocks the arm' 81-; shaft 88 and arm 89 in the same directioriamovement through the link 96 draws the carriage toward the right '(Figs. 2 7) and toward the rear of theus The Eagerg indie-Ed at 3'1-v(F1g" machine .(Flgs. 1 3) for purpose set and 6)--onto whichthe transfer is to be made" is placedon the table 2| with the'first line'in the case of a new sheet or the next blank line}- forthabove. I

In order to align the typed matter on thev ledger' sheet there is' provideda plurality of index fingers 5| (Figs. 5, 6, 11, and 14) slidablyv mounted on a rod 52 supported betweenthe the bell crank as is original sheet with the proper column on the.

downwardly extending arm is connected by a arm of the lever against a stud 98 projecting frames 22 and 23. The ledger sheet 63 (Fig. 14')-- is placed in position on the table 2| andmanually shifted to position beneath the pressure bar 83 at which point it is directly under the fingers 5|. The fingers are now adjusted along the rod 52 to-bring the fingers in line with the limits between-which it is desired to have the transfer appear as indicated in Fig.'14; '-With the fingers 5| in their selected positionsthe original sheet is inserted and the first line of typed matter is positioned as'indicated in'Fig. 14 with the top of 'the typed matter aligned with the'. bottoms of.

the fingers 5| and the first and last characters in line with the notches in the left-hand and r right-hand fingers 5| respectively. The arms m- I (Flg. 11) are now operated to bring the rolls I30 into contact with the roll I31 thus holding the original sheet I53 in position.

Thebar-ii which supports the line finder 04 (mg. 6) is adjustably siipported in slots in the side members or plates IN and I02 of the moisture reservoir, to permit adjustment of said bar and the line finder 04 toward and away-from the index fingers 5|. The purpose of this adjustment is to vary the line spacing on the ledger sheet 03. It will be'remembered that the ledger sheet receives an-invariable movement fromL-line finding position to transfer position. Obviously if the line finder 64 is adjusted closer to the transfer position the spacing of the lines transferred to the ledger sheet will be increased, and if the line finder is adjusted farther from the transfer position the line spaces on the be decreased.

Moistenino device 1 It was stated above that the medium'for applying the solvent to the area to be transferred ledger sheet will comprises a ribbon. This ribbon, indicated at 30v in Figs. 5, 6, and 10, normally rests in a solvent reservoir comprising a channel member I integral with side members "I and I02 which rest receiver tube I08 so that the end of the spout I01 rests on the wick I05. When the machine is in operation it rests with the table 2I at approximately the angle indicated in Fig. 2 in which position the level of the solvent is substantially as indicated by the dotted line I09 (Fig. 6). The purpose of the pad I on the bottom of the reservoir upon which the end of the tube I01 rests is to control the level of the solvent in the reservoir. If the end of the tube I01 rested on the bottom of the channel member I00 the level of' the solvent would fall until the aperture of I01 was uncovered. Then a sudden rush of liquid would raise the level too high. By use of the pad I05 the liquid is absorbedfrom the supply I06 as it is used maintaining the-level constant.

The pad I03 (Fig. 6) comprises a length of wick next to the angular plate I04. On top of the wick is a plurality of thicknesses of blotting paper and finally on the blotting paper is a length of fabric having a vertical pile or nap. It has been found that this arrangement of materials provides the correct degree of moisture for the ribbon 99 and that the nap obviates the tendency of the ribbon to stick to the pad as is the case when a comparatively smooth fabric is used. The purpose of the piled fabric I03 is to control the amount of solvent reaching the ribbon. Also the pile permits the entire length of ribbon to leave the pad when it is moved to moistening position. 'If the pad I03 were provided with a flat surface of closely woven or fabricated material the center portion of the ribbon would have a tendency to adhere when the ribbon is moved and the snap of this portion of the ribbon would throw small drops of solvent onto the sheet I53 causing the carbon to run and resulting'in a smudged copy.

otally supported in the end plates MI and I02. Springs II2, one on each-arm IIO support and tension the ribbon between said arms. The ribbon,- as previously stated, normally occupies a position in contact with the pad I03 it being pressed thereagainst by the weight of a cover II3 fast on a shaft II4 journaled in the plates IM and I02. At the proper time the cover H3 is raised and the ribbon 39 is swung to the position in which it is indicated by dotted lines 33' (Fig 6). The mechanism for raising the cover H3 and operating the ribbon arms III will now be described.

Referring to Fig. 10, a cam II5 on the shaft 38 rocks an arm 6 on the shaft 15 counterclockwise against the tension of a spring I33 and by a connection II1 rocks a lever III cl0ck-' wise. The lever H3 is pivoted on astud projecting-from a bracket I34 secured to the bar 24 I andl has its upper end formed to cooperate with a stud H9 carried on the free end of an arm I20 fast on the cover shaft II 4. The clockwise movement of the lever IIO rocks the arm I20 and the shaft II4 counterclockwise against the tension of a spring I3I to raise the cover II3 The ribbon 9a is carried, tightly stretched, between arms IIO (Fig. 5) fast on ashaft III pivfrom the position shown in Fig. 10 to the position shown in full lines in Fig. 6.

When the cover H3 is partly. open the lever H8, continuing its clockwise travel, strikes a stud I2I on a gear sector I22 free on the shaft .4 rocking said sector counterclockwise against the tensionof a spring I32. The sector I22 meshes with a gear I23 fast on the shaft III, the gear I23 and shaft III being thus rotated.

clockwise to swing the ribbon arms IIO to the position indicated by dotted lines at III! (Fig. 6) in which/position the ribbon 39 occupies a position 39' in the downward path of a platen I24 mounted in the channeled lower edge of the pres sure bar 83, just before said bar starts its downward movement.

- Pressure bar being disposed near each end of said shaft. The

right-hand arm I21 (Fig. 3) is connected by a link I29 (see also Fig. 2) to one arm of a-bell crank I30 pivoted on the shaft 15. A pair of cams I 36 on the shaft 38 cooperates with antifriction rollers on the bell crank I30 to rock it first clockwise and then counterclockwise to norinal. The clockwise movement of the follower through the link I29, arms I21 and links I lowers the pressure bar 83 to cause the transfer and the counterclockwise movement of said bell crank I through the same linkage raises the pressure bar to normal I Paper feed-original Referring to Figs. 1, 6, and 7, a feed roll I31 is secured on a shaft I38 journaled in the frames 22 and 23. A plurality of pressure rolls I39 each wheel I44 (Fig. 7) with which cooperates a spring pressed feed pawl I45 carried on anarm I46free on the shaft I38. A I41, connects-the arm I46 to an armI48 pivotally supported on the frame 22. An anti-friction roller 1149 normally 1 'frests' on the flattened end of an arm I50 secured t the shaft 88.:

It will be remembered that the shaft 88 rocks first, clockwise and then back to normal position under the influence of the cams 84, the arm I50 making a similar excursion (Fig. .7). When the arm I50 rocks clockwise from beneath the roller- I49 a spring II draws the arm I48 and link I41 I downwardly rocking the arm I46 clockwise to remade, indicated at I53 (Figs..6 and ll), is in-; serted over a shield I54 passing beneath the res-' ervoir I00, between a bar I55 and a plate I56; between the feed roll-I31 and the rolls I39 and over the arms I40. The shield I54 mounted on a rod I51 extending between the plates I01 and I02 and is further supported by brackets I58 (only onebeing shown) secured to said plates. The bar- I55 is carried between two arms I59. (see alsoFig. 1) pivoted on a shaft I60 supported inthe brackets I43. A spring I6I holds the arms I59 and the bar I55 in the position in which they-appear in full lines in-Fig. 11. The plate I56 is secured to the shaft I60 and is normally held in the'position in which it is shown in full lines in Fig. 11 by springs I62 (Fig. 1) attached .to levers I63-which are also secured on the shaft I60.

In order to insert an original copy sheet a pair of arms I64 (Fig. 11) is rocked counterclockwise-i These arms are secured one on eachend of a shaft I65 journaled in the brackets I43 and which shaft is provided with notches into which fit the arms I40. Upon counterclockwise movement of I the arms I64 and shaftv I65 the flattened portions of the shaft bearing against. the arms I40 rock these arms also counterclockwise-to separate the rollers I39 from the feed roll I31. During this movement studs I66, one oneach of the arms I40,.contact the plate I56 and carry the latter therewith, the parts being shown in their-moved positions-at I39, I40 and I56 in Fig. 11. This provides afree passage for the original sheet I53 between the bar -I55.and plate I56, and between the feed roll I31 and the pressure rolls I39.

When the arms I64 are restored clockwise to their normal position the springs I4I press the' original between the rolls I39 and the feed roll I31. The clockwise movement of the bar I55 is limited by the arms I59 striking collars on the shaft I38. Adjustable'stop screws I61 are provided to limit the clockwise movement of the lever I63, shaft I60 and plate I56 so that as thejparts I appear in their normal position in Fig. 11 there is a slight clearance between the bar I55 and plate I56 to permit free movement of the original I53 when line spaced as above described.

It is important that the ribbon 99, the original copy I53 and the ledger sheet 63 do not come into physical contact until the instant pressure is applied by the pressure bar 83. The reason for this is that it is desired to produce a clean copy without smudges or smears which would occur if the sheet I53 touched sheet 63 during movement of either, or if the moistened ribbon 99' touched the original sheet I53 before-pressure is applied the solvent would cause the carbon deposit. onjthe back of the original term so upon application of pressure a smudged 'copy would result.

In order to avoid this and produce a clean copy these elements are brought in'toclose proximity but not into actual contact just before pressure is applied and are quickly separated thereafter.

To accomplish this the mechanism described above and iIlustrated'in IE'ig. does not move the ribbon 99 all the way to transfer position but moves the arms IIO which carry theribbon to approximately the Position indicated by dotted lines at 0' in Fig. 6, in whi'ch position the arms IIO lie in the paths of arms I 68( Figs.'5 and 6) pivotally mounted on the pressure bar 83. Also mounted on the pressure bar 83 are latch pawls I69 and stretched between arms I68 and pawls I69 are springs I10. Ears I1.I on the pawlsI69 extend beneath the plates"IOI and I02; holding the pawls I69-disengaged from their associated arms-I68 when the bar 831s in its uppermost position.- I My As the pressure bar -93 commences its d wnward movement-the ears I1I move away from the plates "I and I02 permitting springs 110 to rock arms I68 until projections I12thereon come into-con tact with ears I13 on the arms I68. During the continued downward movem'entof thebar the arms 168 come'into cOntact-With the-ribbon arms,

IIIl and, since the springs I10 (Figs. 12' and 13) are of greater strength than the spring I32 (Fig;

10) the ribbon arms I I0 are rocked further clock wise to the position shown infull lines in Fig. '6'.

' Referring to Fig. 11-. the arms-=I59 which carry the guide bar I55are"provided with bent portions or ears I14 which extend intot-he path of travel of the ribbonarms IIO. ---Projections I15'on the ribbon arms I'-I0 come into contact with theseears carrying the arms I59, the bar-155' and conse- V quently'the original sheet-H53 downwardly from the positionshow'n in Fig. ll 't' o that illustrated in full lines in Fig, 6. Justbe'for 'pressureis applied by the platen I24, said platen, the ribbon-.99. original I53 and the ledger sheet 63' occupy :the positions in which they are'shown in' Fig. 6,-where it can be seen that, "while these membersare close together, they are slightly separated. -Thepressure on the 'arms I59 also presses the bar I 55 downwardly against the'plate 'I56- to grip'the original sheet I53 thus'preventingdisplacement of thissheeta a The movement of the pressure bar -.83 is continuous downw'ard'to applypressure and then upwardly to its normal position. -As the bar continues downwardly from the position shown in Fig. 6, theiarr'ns I59 and ribbon arms IIO being stopped by the plate 2I,'the arms I68 (Fig. 12) rock to the" position 'shownin Fig. 13, the projections I12 moving under the ears I13.- The purpose of thus latching the arms I68 in theirmoved position is to prevent the springs I10 from holding the ribbon arms I I0 and the arms I59 down until the-arms I68 strike" studs I18; in other words,t'o permit a quick separation of the ribbon 99,- original I53 and ledger sheet 63 upon commencement of the upward movement of the bar 83. This quick separation is necessary to prevent smudging and running of the carbon.

. .As the bar 83 nears the end of'its'u'pward stroke the ears "I of the pawls I69 strike. the under sides 7 oftheplates mm m m which assume their-normal'positions in readiness for another operation. a

As soon as the pressure'isreleased the mechanism illustrated in Fig. 7 moves the ledger ,car-

riage to its original position-and the cam 12 (Pig. 8) raises the bar one release the grippers- The operator may now adjust the ledger position on the pad ill in' the solvent rwervoir III. "I alsofpermitsthe spring Iil wise toclose the'coverl II. a

Also near the end of the operation, the paper feed mechanism- (Fig. 7) operates to feed the original sheet'ili one line space.

ReferringtoFlg. 11, the lever It! extends downwardly below the plate or table 2i where it cooperates with a rod ill suitably moimted to slide horizontally in the machine. The lever I83, as set forth above, is rocked counterclockwise upon operation of the arms I 'to release the rollers I39 for the purpose of removing the old sheet 3 .and inserting a new one. This movement of lever IE3 thrusts the rod I10 toward the right opening a pairofcontacts i" which arewired in series with the motor 28. This opens the circuit to the motor to prevent operating the machine while inserting a new sheet.
