Claims. (Cl. BIL-287) The present invention relates to a machine by means of which, on the one hand, inscriptions are produced on individual documents presented thereto in succession, and, on the other hand, inscriptions which may be described as abridged are produced on an audit strip,-which is actuated after each impression by a mechanism different from that which actuates the individual documents, these abridged impressions corresponding individually to each of the effected on the individual documents.

In the present specification the expression abridged impression is to be understood to include inscriptions which contain certain elements of the inscriptions effected upon the aforesaid individual documents, these abridged impressions being constituted either by a portion of the impressions upon the individual documents, or by a summary, which may be codified, of the inscriptions upon the individual documents.

*Machines of this type are known, in which the two kinds of impressions are located one above the other upon a typing unit which is movably mounted in a base underneath the impression head-of a press. With these machines the inscriptions on the individualdocuments and the abridged inscription are printedseparately and successively, owing to the fact that the impression supports for the individual documents and for the audit strip are so disposed relative to each other that they are not simultaneously covered by the typing unit in the impression head. The latter and the typing unit it contains are thendisplaced laterally after the printing of the complete text right into a position overan impression support for the audit strip, for which the remainder of the typing unit no longer bears upon -a support.

Certainother machines are known which have two impression heads, acting alternately for printing the complete-text and theabridged :text. In=thi case the typing unit alone is displaced laterally.

Other machines are known which likewise have a support for the documents to be printed, arranged side by side, this support being displaced laterally with these documents, so as to bring the latter successively over the typing unit, which remains in position, a single impression head being adapted to print the complete text and the abridged text alternately.

These machines have the disadvantage ofnecessitating a double printing operation forthe-reproduction of the complete text and of the abridged text. Furthermore they do not enable the printing to be effected upon the upper or visible face of the documents.

Machines have likewise been proposed which obviate these disadvantages, but in which the abridged inscriptions, instead of being entirely different from the complete inscriptions, form part of these latter inscriptions, and are located beside the remainder thereof. In this case the audit strip passes beneath a part of the individual documents, and theprinting of the abridged text is effected as a duplicate at the same time as the printing of a portion of the complete text. These machine necessitate the use of relativelywide individual documents, and it is practically impossible to effect the impression by means of confidential unit, because this would necessitate the use of confidential unit of excessive dimensions. One is therefore limited in practice to the use of inscriptions made by hand or with a typewriter.

The present invention relates to a machine which enables the inscription of the complete text and that of the abridged text to be executed in -a single operation, in the case in which one of these inscriptions is before the other, or above, or within the body of the complete text, or else eitherbelow, or above, or 'within the body of the remainder of the complete text.

According to one form of construction, the machine com-prises, in addition to a support for sustaining the individual document that -is to receive the complete text but not the audit strip, another support, which is designed to support this strip, and which is arranged, in relation to the first support, either above, or below, the first support.

In the casein which the printing is effected by means of a typing unit mounted in the impression head, andin which the audit strip is arranged in the base, the :ribbon for printing the abridged text may advantageously be arranged over the audit strip, in such a Way as to keep the latter hiddenat the printing place. Because of this arrangement,the possibilities of falsification'of the recapitulatory noteare reduced.

Because the document bearing the complete text normally has to be subjected to verification before it is dispatched, it is not desirable to arrange the printing ribbon of the complete text in the base above the document tobe printed upon, whichwould moreover-render itmore difiicult to place the documents in position for printing in the case where the documents are independent of one another. it is therefore preferable to ually to the printing position by means of a pu hing member which is connected to the movable impression head by a mechanical connection which causes it to advance one-half'of its 'total displacement towards the printing position while the impression head is removed from the printing position, and the other half of its total displacement while the impression head is close to its printing position, the said pushing member being constantly urged to occupy its starting position, and being disengaged from the afore-mentioned mechanical connection at the end of its advancing movement.

This embodiment presents the advantage of reducing the speed of displacement of the documents relatively to cases in which they are advanced throughout their length during one only of the two strokes of the impression head that are effected between two successive impressions.

According to a further embodiment the abovementioned movable head is carried by an oscillating arm which is fixed to two other arms, so arranged that one of them approaches the magazine when the other is moving away from it, and to each of them is articulated a dog which abuts against a pusher stop when it approaches the magazine, and furthermore a cam co-operating with that one of the two dogs which occasions the second half of the stroke of the pushing member towards the front is arranged in the path of this dog in such a way as to disengage the latter from the corresponding stop at the end of the forward stroke of the pushing member.

With a view to obviating frauds, the machine may advantageously be equipped with a thin ribbon support, in which a window aperture is provided at the printing position, Which is interposed between theribbon and the document to be printed upon, this ribbon support being provided, along that one of its edges by which the printed document is pushed out of the machine, with oblique flexible teeth, some directed upwardly and'the others downwardly, to prevent the introduction of foreign bodies between the ribbon and the document. to be printed upon.

Another feature of the machine according to the invention consists in the fact that the device for advancing the audit strip is connected to the impression head by a mechanical connection which causes it to advance one half of the distance required between two impressions while the impression head is removed fromthe printing position, and the other half of this distance while the impression head is close to its printing position.

According to one particular embodiment, the machine comprises a roller for drivingthe audit strip, which may be actuated by two driving devices in a single direction, mounted one on each side of a Wheel which is fixed to the said roller, and set in motion through the medium of links leading to one and the same point which is movable with the impression head.

The machine according to the invention may furthermore advantageously be equipped with a single driving drum for the ribbon serving for the impression of the complete texts upon the individual documents and for the ribbon serving for the impression of the abridged texts upon the audit strip, these two ribbons being spaced from one another.

Finally, with a view to compelling the simultaneous impression of the complete and abridged texts, it is proposed to equip the machine with a device for printing a network of fine lines on the documents, which is arranged between the magazine and the printing station of the complete inscriptions, in such a way as to print automatically, in the course of the displacement of the documents between the magazine and the printing point of the complete inscriptions, a network of fine lines on the face of these documents upon which the complete inscriptions are printed.

Other features and details of the invention will appear in the course of the description of the drawings accompanying the present specification, which represent diagrammatically, and merely by way of example, two forms of construction of a machine according to the invention.

Figure 10 is a perspective view on a larger scale of a part of the machine illustrated in Figures, 6 to 9.

In the various figures like reference characters indicate like elements.

The machine illustrated in Figure 1 comprises a base 2, to which is articulated an impression head 3. This head is carried by arms 4, pivoting about pivots 5 and Emounted in the base. The base contains a first impression support 6, covaccuse:

5 eredwith a layer of hardened rubber, and a -second impression support, consisting for example of a steel roller covered withhardened rubber, and capable o'l' pivoting about a pivots.

The machine illustrated'is'intended for printing *simutlaneously a complete text and an abridged text, both carried by a typing unit 9 (Figures 1 *and'z), which is engaged in the impression head. This'typing unit comprises a part, marked l in'Figurezwhich corresponds to the location of the complete text, and another part, denoted by l I, which corresponds to the location or the abridged text. It will be understood that the corresponding parts of the typing unit project from the lower face of the latterbelow the parts l0 and N, particularly fromthe fact of the embossing of the texts.

A-front flange l'2 forming a slideway serves to maintain a'label [3, which facilitates the sorting of'the typing u'nits. Tw'oiateral flanges M serve to facilitate the introduction of the printing slug 9 into thei'mpress'ion head -3. In the case illustrated, the abridged textis'located underneath the corres ondin 'complete'text. For this reason, the corresponding impression support, consisting df'therolleriis arranged'before the impression sup ort 6 corresponding to the complete text.

-The printing of the abridged text is eifected upon the audit strip l passing over the roller 1. This'stripcomes from a roll [6 (Figure 3) and is moved in the direction of the arrow X'by two rollers l1 and i8, between which it is pressed. One of 'thesero'llers,fin the case of the machine illustrated, the roller markedll, is rigid with a ratchet wheel l9 '(Figure 4), with which there meshes a pawl "20,'which is displaced at each impression by the movement of the impression head. This pawl may for example form part of a rodZ'l, articulated at 22, to a connecting rod 23ydrivenby a crank 24. The latter is keyed on to' the pivot 5. As will readily be seen, each time the impression head 3 moves away from the base 2, the pivoting of the arm 24 in the direction of the arrow Y occasions the displacement of the pawl 'in the direction of the arrow Z and drives the roller I! in the direction of the arrow R, corresponding to the advance of 'thestrip l5 in the direction of the arrow X. The movement of theimpression head 3 towards the base 2 does not cause any displacement of the rollers H and [8, since the pawl 20 slides freely over the teeth of the ratchet wheel l9. The length of the crank 24 should obviously be so selected that "the stroke of the roller I! will correspond at each impression to the height of the spacingof the abridged texts.

The printing of the abridged text upon the auditstrip is 'efiecte'd by virtue of the interpositi'on-"o'f aprinting ribbon between the typing unit land the roller 1. This printing ribbon, a portion of which has been shown broken away in Figure '1, in order to render visible the roller I mounted in the base, ismarked '25 "at the two places where it issues from "the base *2. This printing ribbon is -"di's'place'd' at each impression as "a result of the movement of the impression head. It is movable transversely in'th'e direction of "the arrow S or in the opposite direction, that is to say, transverselyto the directionof advance of the audit strip [5. To this end it is mounted upon spools the axes of which are horizontaland Figure 5, together with the mechanism that actuates it. It is denoted by 26. One of its flanges isirigid with :'a ratchet wheel 21, in the teeth of which there engages the extremity 28 of a rod 29'which is bent into the shape of a swans neck. This rod is so mounted as to be able to pivot about an axis substantially parallel to theaxi's of thespool 26, in a lever'30 pivoting about a pivot 3I,'the axis of which is horizontal and *is'perpendicular to the pivotal axis of the swan-neck rod 29. The lever 30 is subjected to the action of a return spring 32, which constantly tends to'make it pivot in the directionof the arrow T, but it can beset in rotation in'the direction opposite to this arrow when a cam 33 (Figures 1 and 5), integral with one of the arms '4 carrying "the impression head 3, moves in the direction'of' the arrow U in the course of the downstroke of the impression head.

During this downward movement of the head, the'iend 28 ofthe swan-neck-shaped rod 29 slides over the teeth of the ratchet wheel '21 in the manner 'of a p'awl, but during the upward movement of theimpression head under the action of areturn'spring '34 (Figure 1),"the end 28 of the swan=neck shaped rod moves the ratchetwhe'el 2.1 in the "direction 'ofth'e arrow V (Figure 5).

The'printing ribbon25 is wound upon the core of 'the sp'oolzli in such a way asto move in the direction'of the arrow S'under'the action ofthe rotation of the spool in the direction of the arrow V. The ribbon thus displaced unwinds from a spool 'similartothe spool-26, but situated in the base 2 on the side opposite'to that in which the spool '26 is located.

To allow the ribbon to unwind, this second spool must be free to revolve, but, since it is desirable to "be able to displace the ribbon 25 in the direction opposite to that of the arrow S when it 'ishalmost'completely wound upon the spool'2'5, it is provided, according to the invention, that this second spool should be arranged like the spool '26, andshould becap'able of being set in rotation by a mechanism similar to that which has just been described.

The *swan neck-shaped rod of this second mechanism should be capable of being brought intoa position' in which it is'not engaged in the teeth of the corresponding ratchet wheel'whiie theribbonisbeing driven in the direction of the arrow S. "Similarly, the swan neck-shape'd rod 29 must be capable of being kept out of engagement with the teethiof the ratchet wheel 27 while thefribbon is being driven'by'the other spool in the direction oppositeto'thatof the arrow S.

The-complete text carriedby the typing unit 9 isprinted upon tickets'brought on to the impression support 6, by means of a printing ribbon 35 mounted upon the impression head 3, this ribbon being displa'ced at'each impressionas a result of the movement of the impression head. 'To this end it is mounted upon spools 36 and 31, each rigid with a ratchet wheel denoted by 38 and 39 respectively. The teeth of these ratchet wheels can come into contact with "a swan-'neck-shaped ro'dfat'th'e end of Ithenpward movement of the head 3. The two swan neck shaped rods are denoted ;by "4!! and 4|. Each or these rods is so mounte'd'asto be able to pivot about an axis'substantially parallel to the axis of the spools 36 and 31 when the latter'a're moving in its vicinity. The two ratchet wheels oo-operate with the swanneck-shaped rods in such a way as to drive the ribbon in opposite directions, but of course only one-'o'f the "swan-'neck=shaped rods is in contact with the corresponding ratchet wheel at any given time.

If it be assumed, for example, that the swanneck-shaped rod 4| is in contact with the teeth of the ratchet wheel 39, the swan-neck-shaped rod 40 should be held out of engagement with the teeth of the ratchet wheel 38. Under these conditions, at the end of the upward movement of the impression head, the meeting of the teeth of the ratchet wheel 39 with the swanneck-shaped rod 4! occasions the rotation of the spool 31 in the direction of the arrow W, while the ribbon 35 unwinds from the spool 36. When the ribbon 35 is almost completely wound upon the spool 31, it can be wound on to the spool 36 by bringing the swan-neck-shaped rod 40 into contact with the teeth of the ratchet wheel 38, and disengaging the swan-neck-shaped rod 4| from the ratchet wheel 39.

The individual documents intended to be printed upon in the machine illustrated are relatively thick documents. They are stored in three magazines, one of which is arranged at 42, behind the p-rinting position, and the other two at 43 and 44, one at each side of this position. The documents stacked in each magazine have for instance a color different from those stacked in an other magazine. They are used at will by the operator according to the category of individual document to be obtained. In these magazines the documents are stacked as represented in Figure 3 for the magazine 42. Each pile of documents is constantly urged upwards under the action of a counterweight 45. A slideway 46 is provided above the stack in question, and a pushing member 4! is movable in this slideway, so as to enable the operator to push the top document of the pile in question into the common printing position. The pushing member is provided for this purpose with a handle 48, which forms at the same time an abutment for limiting the stroke of the pushing member, corresponding to the positioning of a document at the printing position.

Slideways 46' and 45", corresponding to the magazines 43 and 44 respectively, are so arranged that pushing members denoted by .49 and 50 can move the documents into the printing position. The pushing member 49 is provided with a handle 5! serving as an abutment to limit its stroke, and the pushing member so is provided with a similar handle 52.

In Figures 6-10 another form of construction of a machine according to the invention is illustrated, which is designed to print the complete texts upon relatively rigid documents, for instance upon pieces of cardboard such as those utilised as railway tickets.

The audit strip I 5 is carried along in the direction of the arrow X, starting from the spool It, by the roller I7, against which it is pressed-by the roller I8, which is subjected to the action of a spring 99. The actuation of the roller I! will be hereinafter explained.

The pushing member 4'! is connected to the impression head 3 by a mechanical connection which it causes it to advanceby one-half of its total displacement in a forward direction while the impression head is moved away from the impression position. The pushing member 4] advances by the other half of its total displacement while the impression head is close to its impression position. The pushing member is constantly urged to occupy its starting position, and is disengaged from the above-mentioned mechanical connection at the end of its advancing movement.

The arms 4 carrying the movable head 3 arev virtually integral, through the medium of the pivot 5, with two other arms 93 and 94, so arranged that one of them is approaching the magazine 42 while the other is moving away from it. To each of these arms is articulated a dog. The two dogs, denoted by 95 and 96, bear against abutments 91 and 98 respectively on' the pushing member 41 when they are approaching the magazine. A cam 99 co-operates with the dog 95, which causes the second half of the stroke of the pushing member in the forward direction, so as to disengage this dog from the corresponding abutment 9! at the end of the forward stroke of the pushing member. This cam 99 passes into a slot 100 formed in the pushing member 41. It is so arranged as to occasion this disengagement slightly before the impression head has reached its impression position.

It is to be assumed that the impression head is in its lowered position, illustrated in Figure 7, forwhich the dog 95 is about to be disengaged from the stop 9'! by the cam 59 if the pivoting of the arms 4 carrying the base is continued in the direction of the arrow U, at the moment when this disengagement occurs the pushing member 4! is returned in the direction of the arrow M- under the action of a sprin ill! until the stop 98 abuts against the dog 96 occupying a position adjacent to that illustrated in Figure 7.

If, after the printing has been completed, the impression head is allowed to ascend again right into a position such as that illustrated in Figures 6 and 8, for example under the action of a return spring, not shown, the dog 95, in striking against the stop 98 of the pushin member 41' under the action of the spring I02 attached to the arm 94, pushes the pushing member 41' in the direction opposite to that of the arrow M to an extent equal to half the total stroke of this pushing member. In the course of this displacement the bottom document in the pile contained in the magazine 42 is pushed toward the printing position 6 by a distance equal to half its length, at the same time as the dog 95 is re turned from the position shown in Figure 7 to that of Figures 6 and 3. If the impression head is then lowered, the pushing member 41 continues its stroke in the direction opposite to that of the arrow M, because the dog 95 has come into contact with the stop 91 under the action of a sprin I03 fixed to the arm 93, and is approaching the magazine 42 while the dog 96 is moving away from it.

In passing from the magazine 42 to the printing position 6 each relatively rigid document I04 passes underneath a device for printing a network of lines on this document. -This device includes a marking roller H15, surmounted by an inking roller I06, pressed against the latter under the action of springs till. The network is printed automatically upon that face of the documents I04 upon which the complete inscriptions are printed by the impression head.

. Seeing that between the position where the network of lines is applied and the exit of the printed documents from the machine the latter are covered by a plate I08 concealing th ribbon and provided with a window aperture 169 to permit the printing, it is not possible to print the complete text partly on a document I04 and partly on a thin sheet covering it without this thin sheet having been introduced into the machine through the magazine. Consequently when the printed document issues from the machine part of its surface would not exhibit the network of lines. It results from this that it would not be possible to complete the inscription of this document fraudulently by means of a typing unit not arranged in the impression head, without it bein evident that the complete in.- scription. has not been wholly produced in the machine simultaneously with the production of the corresponding abridged inscription.

As will beseen, the document magazine" is so arranged in relation to the printing position 6 that the printed document is pushed individually by the pushing member ll beyond the printing position through the medium of another document, expelled from the magazine during the removal of the impression head following a printing operation.

When the impression head is raised again, it is-easy to take hold of the document that has just been printed, since it is already partly projecting from the machine.

The impression over the first impression support Sis effected by means of a ribbon I It, which passes between the ribbon-hiding plate I63; and a; thin supporting ribbon III (Figure 10) provided with a window aperture H2 enabling the ribbon Ililto be pressed onto the document I04 that it is to be printed on.

The thin ribbon support, III is provided along the edge by which the printed document is pushed out. of the machine with flexible teeth II3, directed obliquely upwards, and withflexible. teeth These. inclined teeth H3 and IM are for the purpose of preventing the fraudulent. introduction of thin documents between the document to be printed upon and the printing ribbon.

In the intervals between the teeth H3 and I I4 are arranged other oblique teeth H5, forming a deflector, which deflects upwards the printed document expelled from the machine. These teeth. H5 likewise help to prevent the introduction of foreign bodies between the ribbon H and the document ice to be printed upon.

In order to prevent the document that has been printed upon from catching in the ribbon H6 that serves for printin the audit strip I which passes. in front of the place for printing the individual documents, and to assist in the disengagement of the printed document when the latter is pushed out of the machine, a covering ribbon. II? is provided, in which a window aperture H8 for printing is formed, this covering ribbonextending not only above the ribbon IIG, which. is spaced away from the ribbon IIEI, but likewise obliquely towards the individual document in its printing position, and right below this document. The oblique part of the covering ribbon if? is denoted by M3. The ribbons Ill! and H6 are actuated by a single driving drum,.while kept spaced away from one another. This drum is denoted by I26. It is rigid with a pivot IZI, on to which is keyed a ratchet wheel I22, whichcan be set in motion when a detent I23 is raised. This detent-is mounted at I24 upon a piece 525, having a vertical alternating movement at each printing movement. This piece, I25 is rigid with a spindl I25, which slides in ahole. in a claw I2? formed atthe end'of a bent lever i253, rocking about a horizontal pivot I29. This bent lever is connected by a link I with; the arm at, which oscillates together. with the armsd. carrying the printing base.

H4, directed obliquely downwards.

When the ribbons III] and: H53 have reached the end. of their travel in. one direction they can be driven in the oppositedirectionfby being automatically wound up by; a single drum, from which they have just been unwound. This displacement in the oppositedirection is released by manipulating; a lever I3I pivoting, at I32 and engaged inv a. fork I33provided at the. end of a lever whichzisbent both horizontally. and vertically. The intermediate flange I34 of. thislever pivotsabout a-vertical axis I35, .while the. vertical flange: I36 comprisesa claw I31; in which slides the end of the piece- I25. Thev displacement of the lever I3I in the; direction .of the double arrow N inFigure 8 therefore causes the displacement of the claw I37 in the.-directi0n of the double arrow P in Figure 9;

The-oscillation of the piece I25 about-its pivot I38 occasions the; disengagement of the detent I.2.3;from the teeth of. theratchetwheel I22, and theengagement of another. detent I39. in the teeth of a ratchet wheel I49, keyed upon the-pivot of the; drum that is to cause'the displacementof theribbons-I It and. I-Ifiin the directionopposite to that which has been described above.

The displacement of the audit. stripv I5. is effected in twostagesjust. like'that of the documents to be printed upon. To this end the roller Il is rendered rigid with aratchet wheelv H, which can beactuated by one or the other of two pawls I42 and I.43,,each articulated to an arm mounted looseupon the pivot of the roller I'I. These two armsaredenoted by I44 and. I45. Thetwo pawls I42 and I43 are; mounted oneon each side-of the ratchet. wheel. MI. The arms I44-and, I45 are connected by. links. I46 and M1 to the same'point I48 on the arm 94. It follows that at each oscillation of the impression head in the direction. of the arrow U or. in the opposite direction, the ratchetv wheel. MI is advanced by a certain-extent, either by the pawl I42 or by the. pawl I43. Any attemptat fraudulent printinguponthe recapitulatory note when the impression head. is raised would be. disclosed by the fact thatthe impression had. been made at. a place. not. corresponding to the normal distance between two successive inscriptions. The. me.- chanicalconnection betweenthe device for advancing, the audit strip and: the impression head can therefore advance theaudit strip half the extent required between two impressions, while the impressionheadis-movedaway from the impression.position,.and. by the other half of this extent while the impression head is close to its impression position.

The machine according. to the. inventionmay also advantageously be equipped with a numberingdevice, which automatically prints upon the recapitulatory note the number of successive impressions effected. In. this case, when utilising in the machine individual documents which have been previously numbered and which. are stacked. in. the order of their numbers, it. is possible ultimately to discover that oneor other of these documents has beenremovedfrom the series for the purpose of. being fraudulently printed upon apart from. the. machine.

It is; evident that. the. invention is not: exclusively limited to the forms of construction illustratedand thatv many. modifications can be made in the, form, the arrangement and the constitution of certain of the elements involved in its construction, on condition that these modifications. are. not. opposed to. the. subject matter in each of the following claims.

What I claim is:

1.
