To all whom it concern:

Be it known that citizen of the v United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in; Check Writers, of which the following is a specification.

This invention relates generally to printing machines, and has particular reference to what are commonly known as check writers because of the fact that they are used mainly to write in the amounts. of bank checks and similar instruments.

One'object of the invention is to provide a satisfactory mechanism, separate from, but operating adjacent to the printing type and platen, to shred, break or otherwise disrupt the fibre of the material prlnted upon so thatthe ink used in printin may more readily penetrate the materia and thereby increase the difficultyvof erasing or altering the inscription.

Another object is to provide a mechanism I such as just described, which will have certain advanta es over prior devices of the kind. One a vantage isthat the improved mechanism is actuated to disrupt the paper or other material directly and positively by movement of the operating handle or corresponding prime mover of the machine. As

a result, when the improvement is ap lied to machines constructed to print by ro ling engagement of the type and platen the mechanism is driven in a fixed relation to the moving printing elements, and the paper is never subjected to a grinding action by the type and platen, or to any other strain or stress which might cause it 'to be torn or otherwise improperly mutilated.

With the above and incidental objects in,

view, the invention consists in the novel combination and arrangement of parts, a preferred form of embodiment of which is hereinafter described with reference to the drawings accompanying and forming a part of the specification and the features of novelty of which are pointed out in the appended claims.

Fig. 5 is a section on the line Fig. 1.

Fig. 6 is a top plan viewof the platen-and paper-disrupting devices and their operating connections.

The machine to which an embodiment of the invention is shown applied in the accompanymg drawings is of a type well known on the market and which is shown and de- I scribed in U. Letters Patent No. 1,138 330, issued May 4, 1915, to L. M. Todd and G. Tiefel. Such machines have a type carrier provided with word type forms of difi'erent lengths, and a rotary rinting platen. The type carrier is first adjusted to set the de sired word type form opposite the platen, after which a main-operating mechanism is actuated to actuate the type carrier and thereby effect a rolling printing engagement of the type and platen. The co-operatin faces of the type and platen are. corrugated or otherwise roughened, and co-operate to break or disrupt the fibres of the paper as an incident to printing.-

In the form the present invention takes when applied to a machine of the Todd and Tiefeltype the faces of the type and platen may be left smooth, and the shredding or disrupting action upon the aper is erformed by an auxiliary mec anism w ich comprises two differentially rotatable rollers, one above and the other below. the work, and havin their work-enga 'ng faces corrugated or ot erwise roughene to break or loosen the fibres as the work passes between them. Preferably these rollers are positioned to do their work in advanceof the printin A dierential mechanism is provided for driving one or the other of the rollers, preferably the upper one, directlyby movement of the main operating mechanism to extents corresponding with the lengths of'the words printed; This diflerential mechanism is controlled to determine the extent of movement of the driven roller by the same mechanism as is used in effecting the above-mentioned movement of the type carrier to setthe various word type forms in printing relation with the platen.

In the form shown the differential mecha-' nism comprises a set of toothed elements, one for each word type form, graduated to correspond with the lengths of the-associated type forms. Common tothis set of toothed work-breaking roller.

elements is a pinion or gear acting through suitable connections to drive the upper The construction is such thatwhenthe type' selecting mecha-. nism has been operated to set the desired word type form in position to co-operate with the platen, the corresponding toothed element will be in position to co-operate with the driven gear.. The subsequent operation of the machine to efi'ect enga ement .of the type and platen to print the esired word'will cause the toothed element to act upon the driven gear and turn it .a distance corresponding to the length of the t e. ti' nsmitted through the connections mentioned to the work-breaking roller.

The Todd and Tiefel machine has a central shaft '10 journalled at its ends in'the case 11 of. the machine. Secured to the shaft is a gear 12, Fig. 2, meshing with a pinion 13 secured to the inner end of a short shaft 14 journalled in a boss 15, Fig.

1, on the'casing'. Attached to the outer end of the shaft 14 is a handle 16 by means of ,Which the shaft 14 may be turned. This movement ofthe shaft 14 is transmitted by the gears 13 and 12 to the shaft 10 and as the gears 13 and 12 are of the same size each turn of the handle 16 will result in a "complete rotation of the shaft 10. A type carrier 17 is splined upon the shaft 10 so that it may be adjusted to different positions along the shaft but will turn with the shaft when the latter is rotated. The face of the type carrier is rovided with a number of word type orms 18 of various len hs. Y

or the purpose of moving the carrier to difierent positions on they shaft there is provided a yoke 19, the ends of which are looseupon and surround theshaft 10 so that if the yoke is moved endwise of the shaft the type carrier is carried along. ,Near one end the oke is provided with a handle 21, Fig. 3, integral with which is a pointer 22 co-operating with. an index plate 23, Fig. 1, to guide the operator in adjusting; the yoke and thereby the type carrierto ilferent printing positions. 1

Under the typev carrier is a laten wheel or disc 24, Figs. 3 and 6, 'rotatab y supported between arms of a yoke 25 secured to a shaft 26 journalledat one end in the casing and at the other end in a cross bar 28 integral with the casing. Secured to the end of the shaft 26 is an arm 31, Fig. 5, having its up per end formed to co-operate with a cam 32 secured to theshaft 10. The configuration of the cam 32 is such that when the shaft -10 is rotated clockwise, Fig. 5, the leverv 31 and shaft 26 will be rocked in the same direction against the tension of a spring 33. This will cause the platen 24 This movement 'of the gear will be to be swung into the-path of travel of the type form which has been set in printing re ati on to the platen and held stationary long enough to co-operate with the lon est the material in advance of the printing.

These rollers are positioned oneabove and one below the work-receiving slot and are separable to permit insertion of the work.

Before any word can be printed the rollers are brought together to act upon the paper, and remain in that relation until. after the printing of the desired inscription is completed and the rollers separated to permit removal of the paper.

The upper one of the rollers is designated by the numeral 35, Fi 3, and is secured to a shaft 36, (see also Fi The lower roller 38, Figs. 3 and'6, isloose upon a rod supported between the side arms of a yoke 39 attached to a rock shaft 40. This rock shaft is formed atits forward end, first toward the center line of the mas chine and then upward, the upwardly ex tending end being beveled as shown at 41, Fig. 2, to co-operate with the surface 42 on the type selecting yoke- 19.. When the pipe selecting'mechanism is operated to set -e on t e selecting dial, the surface 42 of th type selecting yoke will act upon the end 0 the rod 40 to rock the rod counter-clockwise, Fig. 3, against the tension of a spring (not shown), thereby lowering the roller 38 to permit insertion of the paper. When the pointer 22 is moved to any other position the tension of the spring is released and returns the roller 38 into engagement with the roller 35.

The'fa'ees of the rollers 35. and 38 may be corrugated or roughened, according to any desired plan so that they will cooperate to disrupt the paper and permit the ready peng. 1) supported b brackets 37 attached to-the machine casd:

ointer 22 opposite the word Release etration oflthe ink. In order to insure firm engagement of the rollers there-is provided genomes the paper in the line in which the payeesname is usually written on a check.

The mechanism for difierentially driving the roller 35, and, of course, the roller 53,

distances corresponding to the length of theword rinted, comprises a set of partial gears esignated agenerally by the numeral 54. These parti gearsare fast upon a shaft 55, journaled at its ends in arms 56 extending from the end members ofthe type selecting oke 19. A stifiening bar or'rod .57 extends thru all of the toothed elelments 54. I

Rotation of the partial-gears or elements 54 is efiected when the handle 16 is turned to rotate the ty e carrier 17 into engagement with the aten 24 to print. For t is purpose there 15 provided a gear 61 rigid with the type earner meshing with a pin on 62 rotatably mounted on the yoke 19 and which in turn meshes with a gear 63 rigid with the shaft 55 and elements 54. It is apparent that at each-turn of the handle 16 the shaft 55 and the parts thereon will be rotated. I V I A shaft 64 rotatably mounted 'above the toothed elements 54 has fastened thereto a smallgear 65. Near the other end ofthe shaft 64 is another gear 66 meshing with an intermediate gear 67 which in turn meshes with a gear 68 loose upon the central shaft 10. The teeth or thegear 68 are atall times in engagement with theteeth of a smaller gear 69 secured to the shaft 36 prevlously mentioned.

The toothed elements 54 are in alinement with and each with a single exception has a number of teeth corresponding to the lengths ofthe associated type forms 18.-

When the type selecting yoke 19 is moved to position the desired type form 18 in opcrating relation with the platen 24, the cor responding toothed element 54 will be set in alinement with the gear 65. Subsequent operation of the handle 16 to effect printing rotation of the t e carrier will cause the shaft 64 to be driven an extent determined by the number of teeth on the positioned element 54.

As stated above, there is one exception to having the number of teeth on the elements 54 correspond with the lengths of the associated t e forms. This exception is found in the e ement 541 in almement with the t pe form tor printingthe word Exactly. n operating the machine shown in the drawings the word Exactly is printed first, with the words representing the amount following in the usual order. The gear 541 at the Exactly position has a toothed portion. considerably longer than being such that almost immediately after the operation of the handle 16 is begun the teeth of the ear 541 will begin to rotate the shaft 35 an roller 35. As a consequence, the paper will be disrupted and fed tar GllOllgll for the disrupted surface to be in position to 'recelve the impression by the tiling the Exactly type form engages the p a en.

The gearing above described is so proportioned that the periphery of the roller 35' and, of course, the associated roller 52, will move at the same peripheral speed as the type, when the type pass across the platen 24. As a result of this construction, the work of the rollers 35 and 38 is erformed in proper time relation with the printing action of the type and platen, and the aper is relieved fromany strain or stress etween the prmtlng polnt and the point where it is'disrupted. 1

j In order to insure holding the differential gearing in proper position to be en a p d b the teeth on the different elements hi her-Z is provided a means forlockingthe shaft 36 against movement between printing operations. As shown in Fig. 5, the arm 31 previously mentioned is provided with an extension 71, carrying a stud 72 normally in engagement with the teeth of the gear 69. When the arm 31 is rocked by the cam 32, as previously described, the stud 72 will be disengaged from the gear 69, thereby freeing the gear and connected parts for rotation. When the cam allows the arm 31 to return to its normal position, the stud will re-engage the gear to aline and hold the various parts in proper position ready for thenext operation. I

The inking mechanism may, of course, be of any suitable form, but in the drawings it is shown as comprising rollers 73 and 731, supplied with ink of one color, vand rollers 74 and 741 supplied with ink of a different color. As the type carrier 17 isrotated, the type contact these rollers to replenish the supply of ink on the type.

In describing the invention it has incidentally been necessary to point outthe different steps of the operation, so it is believed that the statement of the operation usual at this oint may be omitted.
