MANIFOLDING MACHINE Filed Jan. 8, 1931 4 Sheets-Sheet 4 h/ fizi ze [610C Patented Mar. 21, 1933 WILHELM RITZERFELD, OF BERLIN, GERMANY MLANIFOLDING MACHINE Application filed January 8', 1931, Serial No. 507,540, and in Germany September 20, 1928.

The resent invention relates to an apparatus or sectionally 'mainfolding, "mainly bookkeeping entries, from an original provided with mirror script (reversed script) on to copy sheets, cards or the like previously moistened with an evanescent coating of a readily volatile liquid (such as methylated spirit, ether or mixtures thereof). Previous-' 1y known imprinting machines for this purpose, have notbeen able to be introduced into small and medium sized businesses owing to their expensive structure.

By the apparatus according to the present invention, a machine is. produced which is considerably cheaper and, notwithstanding 'ection its intended purpose of effecting bookeeping in small and medium businesses. The apparatus consists essentially of a base- 2 plate on which the sheet, card or the like to be impressed is laid, and of an impressing roller, around which the originalprovided with mirror script is secured, movably mounted in levers. The impression is cf- 2 fected by depressionof the impressing roller on the sheet to be impressed.

A further feature of the subject; of the invention consistsin the structure of the moistenlng device. The moistening container is movably and spring mounted in a slide, the slide itself can be displaced by" hand along two slide rods secured in the side walls of the machine. Moreover a contrivance is provided on the impresslng roller, by the aid ofwhich after each impression the impressing roller and therewith the original secured thereon can be advanced by the breadth of a line. For

this purpose, a ratchet wheel is fast with the 4 impressing roller, in which a pawl spri ng mounted 'on the side wall of the machine en'- gages on raising the impressing roller and advances same a given amount correspondmg to the breadth of a line. By laying back the pawl this contrivance can berendered inoperative and a linealready in position can be impressed-as often as required.

In addition a contrivance isprovided by the aid of which the original can be adjusted exactly in the impressing position on being its simple construction, fulfills without obmounted; .A mirror adjustable to suit the direction of vision by the operator serves for. this purpose. By the aid of this mirror can easily be ascertained even before the beginningof eachnew operative run, which entry is then about to be impressed.

The sheet or card to be impressed is clamped on the baseplate .by means of a clamp.

Constructional examples of the subject of the invention are illustrated on the accomapanying drawings, in which Fig. 1 is a front elevation of the apparatus.

Fig. 9 is a plan of the moistening device. Fig. 10 is an elevation and I Fig. 11 is a plan of the dr'iveof the moistening device.- I l Referring more particularly to Fi s. 1 and 2, 1 and 2 are side walls held toget er by a baseplate 3. In the baseplate 3, at theposition where the impression isefi'ected, a recess 4 [is provided, which serves to receive a counter-pressing strip 5of elastic material, such as rubber. The original 6 bearing the mirror script is wrapped around a roller 7. The roller .7 is rotatably mounted in two curved levers 8'; 9 and 10 are two sheet metal guide plates,which partially cover the roller 7 and are each rockingly' mounted in two spring levers 11 and 12 on both sides of'the rollerpressing levers 8. In the two guide plates 9 and 10 are mounted guide rollers 13 whi rovide a sure guidance for the originalGQ eyed on the spindle of the roller is a ratchet wheel 14', in which engages a spring-in:

I fiuenced pawl 16 mounted on a carrier 15 provided on the side wall 2; The two rollerpresslng levers 8 are secured on a spindle 17,

- which can beangularly displaced by a crank 18. The rotation of the crank l8 is limited rearwardly by an abutment stud 19. A moisteningcontainer. is so mounted 1n 2. sl1de'21, that it can be held in the position shown in Fig. 1 by the action of a spring.

The slide 21 slides on two slide rods 22 and 23,and is held in the starting position by a tension member '24 gut cord or the like), WhlCh led over guide sheaves '25 and 26 winds on a spring drum 27., Inside the spring drum- 27 is a spiral spring, by the action of which the slide 21 together with the moistening' container 20 is constantly drawn back into the osition of rest shown. 28 is a spring clamp, y means of which the sheet to be impressed is held firmly on the baseplate 3. This holding device can be raised with the aid of a A lever 29. i

The mode of operation of the apparatus is as follows In order to'be able to pass the original bearing the mirror script conveniently around the roller 7, the two guide'plates 9 and 10 are so thrust together that they somewhat overlap and so to a certain extent form a continuous sleeve which covers about half the circumference of the roller 7. By the particular jointed mountin of the guide plates 9 and 10 in the small l evers 11 and 12, it results that the plates in the closed together position are somewhat raised from the impression roller. The sheet provided with the original mlrror script can then be easily pushed through between'the roller and the guide plates. The guides plates are then replaced by hand, whereupon the guide rollers 13 press the original sheet against the roller 7.

The sheet to be im ressed is so secured on the impression plate y the clamping device 28 that the line to be impressed rests exactly on the elastic strip 5.

The moistening container 20 is then pressed by hand on to the sheet to be impressed and simultaneously drawn over same. Having arrived at the end of the line to receive the 1mpression, the moistening container 20 is released and is drawn back again into, the initial position bythe action of the" spiral spring in the drum 27 with the aid of the mirror script of the original is dissolved and v transferred to the sheet to be impressed. On

return. oi the roller 7, the'pawl 16 comes into engagement with the ratchet wheel fast with the roller and turns same onwards an amount corresponding to the distance apart of the lines of the original, so that the next line comes into the impressing position.

A mirror 30 let into the basepla'te, enable the correct position for impressing'to be at determine the entry now come to be impressed before the commencement of each new operative run.

In' the above described apparatus the various' operation, such as moistening,-impressing, opening and closing of the card clamp are individually successively effected by different separate actuations. The ap aratus 'can' however be so constructed that t e several operations are effected in a single operation in an interdependent manner by actuation of a handle, lever or the like.

The card clamp in such case is automati-, cally opened and closed by the rocking of the levers carrying the impressing roller.

On' depression of the impressing roller the moistening device is simultaneously drawn over the sheet to be impressed in such manner that the moistening of the sheet is t'erminated before the impressing roller with the lineto be impressed reaches the moistened section of the card to receive the impression. On the outer side of one of the side walls of the apparatus there is for this purpose a cord drum, on which the tension the impressing roller, it is rotated by such spurwheels and thus draws the moistening container over the card to receive the impres-- sion. On return of the impressing roller the.

cord drum rotates in the reverse direction and the moistening container is drawn back again into the initial position.

On the guide bar along which the moistening device slides, tripping devices are pro- ,vided, which on the commencement of the moistening operation lower the moistening device on to the sheet to receive the impression and after completed moist'oning raise it again automatically from'the now moistened card. These tripping devices can be adjusted along the guide bar, so that cards of different widths can be moistened. In its initial position the moistening container projects with its lower protruding felt filling into an intermediate container, secured to the side wall and provided with a notch, which is likewise filled with absorptive material and is saturated with readily volatile liquid from once found on mounting the original and to members, which lead over the sheaves to the ground spirit-tight) arranged above. Thus,

the filling of the moistener which wipes over the card sucks up liquid anew after eagl moistening excursion.

The device for advancing the impressing roller with the original secured thereon, the breadth of a line can be improved by the impressing roller being connected by an adjustable cone with the ratchet wheel, in which the spring-pressed pawl pivoted behind me engages on raising the impressing roller, nd advances same a given amount corresponding to the breadth of a line. The cone can be drawn back by a small lever, so that the advance of the impressing roller is suspended and the line adjusted in position can be impressed several times in succession. This contrivance is also of importance for the adjustment of the line of the original tobe impressed, because with the cone withdrawn the impressing roller permits itself to be easily turned in its bearings, without the ratchet wheel rotating therewith.

In order to ensure exact advance of the original-from line to line, an indicator is provided in the form of a spring-pressed ball which from line to line snaps into recesses provided therefor in and for each tooth of .the ratchet wheel and prevents inadvertent further movement of the impressing. roller with the original stretched thereon, so that the lines to be impressed always positively arrive in the impressing position.

The impressing roller itself can be provided with a pressing bar over which the original providedwith mirror script capable of imparting impressions is looped. This pressing bar serves the purpose of ensuring a completely uniform pressing together of the line of the original to be impressed with the card or the like to receive the impression resting on the elastic base.

Moreover, on the levers or the like carrying the impressing roller, a movable paper support can be provided which prevents the original hanging down behind and smudging the original script.

In order to ensure that the impressing roller, in whatever position it may be, always assumes the same condition, i. e. the

pressing bar and thereby the line'of the original to be impressed always is on the underside, the impressing roller can be rotatably mounted in bearer levers, which are pivotally connected to curved pressing levers fast on a spindle, whereby parallel guidance is effected. As the line to be impressed, is in such case constantly directed downwards, the mirror is then arranged beneath the impressing roller.

In order to have a control as to whether and how often each line of the original is impressed, a marking device isprovided on the' machine, by means of which each line impre'ssedis made known by an ink mark or the like. This marking device is laterally aderal times can be marked in for each impression. 1 4

The above described modifications of the subject of the invention are illustrated in Figs. 3 to 10. In these figures: 1 and 2 are a difierent place side walls held together by a baseplate 3. In

the baseplate 3, at the position where the impression is effected, a recess is provided,

which serves to receive the counter-pressing justable in order that a line "impressed sev-' strip 5 of elastic material, such as rubber.

The original 6 bearing the mirror script is wrapped around the impressing roller 7. On-

the underside of the impressing roller 7 a pressing bar 7 is provided, which is secured to two carrying levers 64. and therefore does not rotate with the roller 7. This pressing bar 7 has the purpose of ensuring com-,

. pletely uniform pressing together of the line the mirror script capable of impressing might smudge. The ratchet wheel 14 is connected to the spindle of the impressing roller by a come 62, which by means of a hand lever 63 alternatively can be either loosened or forced into the boss of the ratchet wheel 14, in order to couple same to the roller 7. The rollercarrying levers 64 are pivotally connected to the two curved pressing levers 8 and 8 The pressing lever 8 is prolonged into a handle 18, b means of which the entire apparatus can e operated. The impressing roller 7 is journalled in the roller-carrying levers 64:, which are pivoted at their rear ends to parallel guide levers 65, which in'turn are pivotally mounted on pedestal hearings on the counter-pressing plate 3. A. parallel guidance of the impressing roller is thus pro- :vided, i.'e. the impressing roller always assumes the same angular situation in whatever position it may be, the pressing bar and the line to be impressed always pointing downwards. Underneath the impressing roller 7 is arranged a mirror 67, in which the line of the original for the'time being on the pressing bar 7 is visible in correctly reading script, so that the impression of the correct line and the adjustment of such line in the correctimpressing position can be controlled.

The card to receive the impression is changed or displaced.

Between the side walls l. and .2 there is a profiled rail 22 on which the moistener carriage 21 runs by means of rollers. The moistener 20 is pivotally mounted on the moistener carriage 21. The moistener 20 projects iii the position of rest with its downwardly protruding felt or wick 20 filling into a notch of an intermediate container 21 which is connected to a reservoir vessel 21. and likewise isfilledwith absorptive material (felt, cotton wool or the like). From .the moistener carriage lead tension members 34 (gut cords or the like), which are-secured to both sides of the moistener carriage 21, over sheaves .36 to a two-part cord drum 35, on which these tension members are wound in opposite directions. The cord'drum 35 is connected by a train of'spur-wheels to the spindle 17 on which the pressing'levers 8 and 8 are fast. As shown in Fig. 10,,the

spur-wheel 37 keyed on the spindle 17 is not toothedthroughout its entire periphery, but has a slipping surface 38, which corresponds with a slipping surface 49 on a spur-wheel 39.

The two spur- wheels 37 and 39 are so mutually set, that when the impressing roller is depressed and the moistening container is in its outermost position against the side wall 2,

the transmission of rotation ceases, because at such instant the slippingsurface 38 and 40 interact. Only on raising the impressing roller 7 do the spurwheels 37 and 39 again come intomesh, and the moistener carriage travels back to its initial position only then when the impressing roller 7 can no longer obstruct it.- I

From the spur-wheel 39 the rotation of the spindle 17 is transmitted in the usual manner by spur- wheels 41 and 42 to the cord drum 35. The cord drum 35 is of two-part construction, the two individual drums of which are united by screws 44. As the screws 44 extend through slots43 inthe outer drum of the cord drum 35, the relative positions of the two individual drums can be varied within limits after loosening the screws 44, in order thereby to adjustthe tension of the tension members The moistening container 20 automatically applies itself to the card to receive the impression and on terminated moistening is automatically raised from the card. For this purpose trip devices are adjustably arranged on the guiderail 22 and which serve both for appl i g l g moistener and also for raising same, for enabling cards of different width to be moistened and impressed. Fast with the moistening container is an eccentric cam disc 23, Fig. 8, over which engages, in the raised condition of the moistener 20, a springinfluenced detent 24 which is provided on the upper surface of the moistener'carriage 21,

clamped in the adjusted position along the guide rail 22 by a screw provided with a lever 33. \Vhen'the moistening of the card to receive the impression has terminated, a release 'pawl 26, pivotally mounted on a lever 25 connected to the moistener 20, encounters an abutment 29 on a raising trip device 27, whereby the moistener 20 is raised. At the same instant the eccentric cam disc 23 frees the spring-influenced detent 24, and this now bolts the moistener 20 in the raised position. The raising trip device 27 can likewisebe [clamped fast at any desired position'along the guide rail 22 by a screw provided with a lever 30. During the return movement of the moistener carriage 21 thepawls26 and 32 resiliently yield to the corresponding abutments, so that thus the moistener 20 remains in the raised position.

The line to be impressed on the original is provided with a distinguishing mark at each impression, so that there is a control as to whether and how often each line is impressed. In the side wall, 1, a spindle 5O ismounted on which a bearing block 51 is displaceably and securably mounted. A stem 52 is guided in the bearing block 51, and carries at' its upper end a printing type 53 and at its lower end is pivotally connected to one arm of a rocking lever 54. On the other arm of the lever 54 is a rearwardly yielding pawl 55, against which, on raising the impressin roller 7, strikes an abutment 56 provide 'on the spindle 17 and thereby so rocks the lever 54 that the type stem 52 presses the type 53 against the line on the pressing bar 7 just impressed. A tension spring 54 is connected to the lever 54 and after each marking draws the lever 54 and thereby the type stem 52 downwards. An inking pad 57 is mounted on the bearing block 51 above the-type 53, and is pressed by a spring 57 against the type 53. The carrier of. the inking pad 57 has a lug 58. On the type stem 52is a projection 59 which on ascent of the type stem presses against the lug 58 on the inking pad carrier and thereby rocks the inking pad, so that the type stem can unhindered reach the impressed line of the original, v I The mode of operation of the above ,described apparatus is briefly as follows: I

The original for impartlng impressions is applied to the roller 7 with the mirror script side outwards and the line to be impressed s0 adjusted that it rests against the pressing bar 7 The card to receive the impression is so slid beneath the then open card clamp 45, that the line which is to receive the impression comes to rest on the elastic counterpressing strip. The handle 18 is then pressed down. Before the impressing roller 7 has reached the card to receive the impression, the moistening container 20, after having yieldingly applied itself, by virtue of the release trip device, against the card to receive the impression, has passed along same. The impressing roller 7 then reaches the moistened cardand the impression is effected. During the now following raising of the handle 18, the moistener container 20 travels back in the raised condition to the initial position, the marking device is actuated and provides the just impressed line on the original with a distinguishing mark and simultaneously the card clamp 45 is again opened and the original is advanced by a line. The impressed card can now be exchanged or another line on the same card can be brought into the impressing position, whereupon-the operations described are repeated.

By the provisionof several adjustable releaseand raising-trip devices, the card toreceive the impression can be moistened at discontinuous positions along a line so as to receive impressions at given pre-determined positions.
