companying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention rel tes to novel proof and transfer presses for taking proofs from forms suitably locked on a bed for proving and registering the forms and thereafter,

without removing the forms from the bed after the same are in register, transferring the impressions from the forms direct on printing plates for lithographic or oil'set,

presses. The press is designed for making either positiveor negative transfer printing plates or elements for lithograph or offset presses from zinc, aluminum, stone, rules, type, or cuts in one operation of the transfer element, in one or more colors. One or more forms can be imposed on a printing plate by direct transfer from rules, type, or cuts, to zinc plate, aluminum, or stone.

A purpose of the invention is to provide a novel construction wherein a proof and a. transfer roller can be so associated with a bed on which the forms are locked and a bed on which the transfer plates, stones, or other elements, are supported that the forms may be first proved up and registered by runnin the proof roller thereover, and therea .ter the impressions from the forms can be directly transferred therefrom by a transfer roller or rollers to a printing element such as zinc printing plates, aluminum, or stone for lithograph or ofi'set work, thus providing means in one simple press for successively proving and transferringthe work,- which may be employed for lithograph work. only or for oflset work only, and, which may a double bed that supports the printing forms ma be adjusted with respect to the proof r'ol er and to the transferroller 'or rollers, so as to compose the printing forms on the rollers or to superimpose them thereon, and to also so adjust the press to forms of different sizes and subjects locked on the bed, such as ruled sheets, color work, and the like. Such adjustment of the bed may be effected either in a direction parallel to the axes of the proof or transfer rollers or in a direction transverse thereto or the adjustment ma be in both directions.

Another 0 ject of the invention is to provide-novel means for so adjusting the bed.

A further object of the invention is to provide means for operating the rollers, constructed and cooperating with means for elevating effective faces of the rollers above the forms and printing elements sothat said rollers ,may be moved lon 'tudinally of the bed withoutcontaet witi certain of the forms or printing plates or elements at times when no contact is desired, and in contact therewith when Such contact is desired. Another object of the invention is to provide a novel arrangement of sectional tracks forsupporting the rollers, in connection with means for giving movement'to the rollers bodily of the bed and printing elements, so constructed and arranged as to elevate the sectional tracks to lift the rollers above the forms and printing elements at certain parts of the travel of the rollers at such time a printing plate, or the like, as a negative impression or directly transferred to a second roller for direct positive transfer to a printing plate for an offset press, or may be directly si-on.

Other objects of the invention are to otherwise improve and slmplify presses. and the invention consists in the combination and transferred from a transfer roller to another to reverse the final impres-' the froxit end of'the machine.

arrangement of the parts shown in the drawings and described in the specification, and is ointed out in the appended claims.

The frame 15 of the machine may be made of any suitable or convenientshape to properly support the elements of the machine and their bearings, and is shown as comprising a horizontal platform-supported on legs or standards. The general structure has an extension 16 for a pur se to be hereinafter described. Suppo on said frame "is, a movable or adjustable printing form and also a bed 65 to supsupporting bed 17 port a printing element 66. The movable or adjustable bed, as herein shown, is made of a width equal substantially to that of the machine frame, and of a length to constitute a double or two bed parts longitudinall spaced on the ma chine frame, with eaci bed part of such length relatively to the effective faces of the proof and transfer rollers that imprints part bed with the from different forms supported on the bed parts inay be applied on a proof or transfer roller, by pro r adjustment of the bed, to

compose simp e or superimposed imlpressions from the formson the transfer ro whence said impressions printing element. Th

porting bed 65 is above the level of the bed 17 so that the latter in its longitudinal adjustment may pass partly beneath the bed 65, as indicated in dotted lines in Figure 1, and so that the." inking rollers may not clash with the bed er, from are applied to a printing plate. sup- .65. The frame 15 is also provided at one end with a transverse extension 76 to sup-- port an adjustable bed 78 for printing plates 77. When such an adjustment is arranged for, the bed 17 may be termed a double bed I in that it is arranged to support two or more spaced forms which are adapted to be registered insuch relation as to'produce ultimate compositions,- whether cross lines or other lines.

For convenience and certainty, the forms supported on the bed 17 are herein termed printing forms, however individually made; the plates 66 supported on the bed 65 are termed negative printing elements, and the plates 77 supported on the bed 78 are termed positive printing elements. These terms are not, however, intended as limiting terms but are descriptive of the present illustration of the invention. 1 I

Said bed 17 supports frames or chases 18 in which are locked in any suitable manner the form 18" best shown in Figure 1'. The particular forms shown in Figure l may be the down and cross line forms that are composed, proved, and properly registered for rinting cross ruled sheets in accordance with the method disclosed in my prior United States Letters'Patent Number 1,210,862, granted January 2,1917. The

cross ruled forms made in accordance with spaces 18 on the bed,'and, as hereinshown,

the transverse width of each space is equal fer rollers and theother dimension of said s cc is equal to one-half-of the length of t e effective circumference of the rollers.

Assuming that proofs are to be made and to one-half the length of the proof and transv registered of down and cross lines of a cross ruled form, as indicated in Figures 1 and 2, after proofs have been taken-and registered from the full line positions of the forms shown inFigure 1, on the proof roller andthe impressions transmitted to a transfer roller to occupy the same position thereon .as they occupy on the proof roller, the bed supporting said forms can be shifted so that the forms occupy some other positions relsitive] to the proof and transfer rollers, but al ways in register, some of which positions are taken by other parts of the proof roller and the lines then are picked up from the printing" forms by other parts of the printing element.

If desired, however, other forms, such as plates, rules, type, or cuts of the same or different colors may be locked on the bed to constitute smaller forms, in which event it is necessary to adjust. the movable bed a larger number of timesin each composition on the transfer roller 'so as to bring the forms in proper registration with the desired longitudinal and circumferential areas of the proof. and transfer rollers.

transfer roller to-be later transferred to the ler, the imprint therefrom to a printing plate or element is made in one' operation of the roller. I I t The said bed 17 is supported to shift laterally on. atable 17' that is movable longitudinally on the frame in a manner hereinafter described. The means herein shown for so laterally adjusing, the movable bed on the tablecomprises a threaded shaft 20 which is rotatably mounted in a suitable bearing 20 on said table and is threaded through a nut 21. that depends from the bed17 (Figure 9). Said shaft is providedwith a handwheel 22, and a graduatedrdial and cooperating pointer 22a (Figures 2 and 5)may be associated with said shaft soas to facilitate the lateral registrations of the forms relatively to the proof and transfer rollers- The extension 16 of the table 17 is provided to support the bed 17 when the latteris adjusted to occupy the lateral position indicated by the dotted linesin Figure 1. i i

The means for adjusting the bed 17 longitudinally of the frame'to register the forms to predetermined peripheral surfaces of the proof roller 25 comprise a rotative shaft 32 that is disposedtransversely of the frame in rear and below the plane of the shaft 20 andis mounted in suitable bearings in the "frame members 32'. Said shaft 32 carries near its ends pinions 33 which are adapted tomesh with downwardly facing teeth of racks 34 of the table 17. The shaft'32 is provided at one end with a hand wheel 35 by which it is rotated, and a graduated dial 35 and a cooperating pointer may be associated with.

the shaft tomeasure the rotations of the shaft and thereby facilitate proof and registration of the forms relativelyto the proof ilIlCl transfer rollers longitudinally of the atter.

The proof roller 25 is located at. the

forward end" of the frame. It is-supported on a shaft 25 that is rotatively mounted in bearings carried by bearer-s40 which are. in turn, supported .on tracks 41, 41%, the latter fixed relatively to the frame and extending longitudinally of-the frame, one set at each side thereof. The former can be vertically adjusted by means and for apurpose hereinafter described. 26, 26 designatesspur gears which are fixed to said shaft 25 and mesh with the upwardly facing teeth of longitudinal racks 27, 27 that are supported on the frame 15 at the sides'thereof andwithin the tracks41. 41','whereby, on rotation. of the proof roller, the latterrcan be caused to rotate on its axis and also to be carried bodily lengthwise of the ad'ustable bed. 'The said proof roller is rotate on its axis and caused to move along the frame bv means of a crank 28 fixed to the shaft 25. The track sections oted at 44 to the machine frame. \Yhen the 130 41 41" are-adapted to be raised in aaysuitable or preferred manner'to lift the proof roller and the transfer roller out of contact with the forms or certain of them and of the printing element, as will hereinafter more fully appear. 29 designates a group of inking rollers of any suitable type associated with an ink fountain and adapted t 1 travel over the forms with the, proof roller when the latter is caused to bodily pass over the bed, to ink said forms in both directions of travel of the roller.

Through the coaction of the adusting shaft 20 and nut 21 of the bed, on the one hand,

and the shaft 32 and the pinions 33 and racks 34 of the table, on the other hand, it will beobserved that the double bed 17 may be shifted either laterally or longitudinally of the 'frame' to effect desired registrationof the It will be understood that the pointers of said dials are geared in any suitable manner to the shafts 20 and 32 to'cause the pointers to sweep over the dials as said shafts are turned to adjust the bed. Such registration of the bed relatively to the proof and transfer rollers maybe made by other known and suitabledevices within the spirit of the appended claims. The shoes orbearers40, in

which the shaft 25' of the proof roller is mounted bear upon the fixed tracks 41 of the frame at the front end of the press or out- ]wardly beyond the form'bed when the proof roller is in its inoperative orretracted position, and when saidroller is moved over the forms. 18' to pick up the proof therefrom said bearers-4O are supported by the 'sectional tra'cks41. \Vhen the forms are of such size asr to occupy less area than all of'the bed,

or when proving and registering, or transferring multi-color forms on and from the bed, respectively, it maybe necessary or de-" sirable in some parts of the travel of the proof roller over the forms to lift the same away'from or out of contact with. certain'of the forms. This can be done when aproof or transfer roller does not travel entirely across the form bed. Such lifting of the proof roller' may be effected by raising the sectionaltracks 41 and said tracks may be raised in any suitable or approved manner. The means herein shown for raising the "tracks are made as follows:

The said track sections are provided a their ends and on their under sides with shallowcam faces adapted to be engaged by the cam inner arms 4:) of levers 43 that are pivcarried by beareres 56 that are adapted to levers 43 are in their outstanding positions 7 or normal to the sides of the frame, as shown in Figure 3,. the arms 45 are engafid with sald cams and serve to, raise thetrac to positions indicated in Figures 5 and 6. When the proof roller is located abreast said tracks and the bearers 40 are supported on the raised tracks, said bearers and the proof roller are raised so as to lift the roller above the forms. When the. levers 43 are swung at oblique angles to the positions indicated in Fi res 1, 2, 5, and 7, the tracks 41 descend to the level of the fixed tracks 41 of the frame to bring the proof roller in contact with the forms on the bed, as desired. It will be understood that the required lift is slight, not suflicient. todemesh the gears and racks. I

50 designates a transfer roller, the shaft 51- of which is mounted in suitable bearings bear on the fixed tracks 41' of the frame,

or upon. the sectional raisable and lowerable track sections 41, depending upon the 25 position of said roller on the frame. shaft 51 of said transfer roller is adapted to be rotated on its axis through the medium of ahand crank 52 attached to the said shaft. At the ends of thetransfer roller are spur 'ears "53' which mesh with the upwardly acing teeth ofthe rack 27, 'above'referred to, whereby when the crank 52 is turned,,and

therethrough the transfer roller 50,-t he engagement of said ars 53 with the tracks 27 causes the trans er roller 50, not only to rotate on its axis, but also to be moved bodily lengthwise of the beds 17 and 65. Thus the transfer roller may be moved over the forms 18' after the same have been proven and registered and said transfer'roller may be thereafter 'moved' backwardly over the bed 17 and to the bed 65-to transfer the impressions received thereby on theprintin elements 66 supported on the fixed bed. on said transfer roller is being moved formay be thus raised to lift the transfer roller out of contact with any one of the forms 18' not to be transferred in anyv articular operation of the machine, or the li ing may occur in other directions of travel ofthe transfer roller.

If the plates 66 on the bed 65 are'to be used as lithograph plateson a litho raph press, the transfer of the forms on sai plate or element will be negative or the same as shown on the forms 18', and said plates after receivin remove to be prepared for the lithograph press and usedas printing plates in the usual t timesit' is desirable to move the transfer roller 50, as well as the proof roller 25, and the transfer roller '70, hereinafter dethe transfer from the roll 50 are scribed, bodily lengthwiw of the bed with heads o' the transfer rollers 5( are provided with keyways 63 and the spur gears rooved to re- 53 are also provided with keyways 62.

When the broad inner ends of the keys 60 are engaged partially in the keyways 63'of the transfer roller, said transfer roller is no locked to the gears 53 so that when the shaft 51 is rotated, through application of power to the crank shaft 52, thetransfer roller willbe caused to rotate on its axis and also to be moved bodily longitudinally over the bed through the coaction of the spur gears 53 and the racks 2.7 When the keys60, 60 are shifted so that their broader inner ends lie wholly within the keyways 62 of the spur gears 53, said gears may rotate with the shaft 51, without, however, transmitting rotationto thetransfer roller 50. In the latter adjustment of the parts the transfer roller may be shifted bodily, through the coaction of the gears 53 and rack 27 with respect to the bed without turning on its axis and ata time when the grippingre-l cesses of the rollers are downmost. he keys may be connected in any suitable manner for mutual operation, as, for instance in thexmanner shown in Figure 4.

When it be desired to transfer the impressions from the transfer roller 50 for positive impression to printing elements for offset press work, the impression from the transfer roller 50 is shown as transferred directly to a second transfer roller'70 that is so mounted on the frame that saidtransfer rollers 50 and 70 may be geared together to rotate in peripheral contact and thereby transfer the impression from one roller to the other, to be by the latter printed on another printing element. 7

The said transfer roller 70 is mounted on a shaft 71 which is rotatively supported on and'iscarried by bearers 71' that are supported directl on the fixed tracks 41' of the frame. he shaft 71 of the transfer roller 70 isprovided witlna crank 73 by whichthe latter roller is turned on its axis,

andthrough coaction of ,spur gears 74, 74 at the ends thereof with the racks 27 before described, said transfer roller 70 may be caused to be moved bodily over and in contact with the printing element 77 to transfer the impression received from the roller 50 to'the positive printing elements for offset work. I

In order to cause the transfer rollers 50 and 70 to be rotated in contact witheach other and at equal eripheral -speeds,'said rollers are connected by suitable gears, at

' their ends,- as for instance, by meshing gears in Figure 3, operative- 72, as best shown when their gears 74 and 53 are inoperative. When the transfer rollers 50, 70 are to be rotated in peripheral contact with each other to transfer an impression from one to the:

1 ratchet release and coacting projections may other, the broad, inner ends of the keys 60, 60' of the transfer roller 50 may be forced inwardly wholly into the keyways 63 of the transfer roller 50, whereby said roller is released from the spur gears 53 so thatthe roller may be rotated however, causing said roller to move bodily relatively to the frame. The transfer roller 70 may be likewise rovided with controlling keys 7 5, by whic said latter roller may be also released from its spur gears 74 so that both said rollers 50 and 70' may be caused to rotate on their axes and in periph eral contact with each other without tendency of moving the rollers bodily relatively to each other, this occurrin when an impression is to be transferre from the r1- mary transfer roller 50 to the secon ary wardly or forwardly transfer roller 7 0, and the impression thereafter transferred from the latter roller to the printing element 77;v

In the operation of the machine, the proof roller can be turned on its axis duringthe time it is being moved bodily either rearover the forms to receive the roof impressions therefrom, and can be rel ased from its gears to move in the other direction so as to be carried bodily in the other direction over the forms without turning on its axis. Said proof roller can return to its normal or inoperativeposition while the interrupted or clam ing recess thereof faces downwardly, or w en one of the pairs of the tracks 41 are raised. The

transfer roller 50 can be rotated on its axis when: traveling either forwardly or rearwardly over the printing forms 18' topick' up the impressions therefrom, and when traveling over the movable double bed can moving either rearwardly or forwardly over on its axis without,

or interrupted recess thereof the printing element 77 and will be disengaged from its gears and return forwardly to its inoperative position without rotating on its axis and with its clamping clearance recess disposed downwardly.

The means herein shown for releasing the gears from the proof and transfer rollers are merely illustrative as one form of such means, but it will be understood that any preferred or known form for controlling said movements to cause themto properly register with the form and plate may be employed. In event that the key means herein shown be employed to effect alternate connection and disconnection of the rollers, the frame may be provided with any suitable cams to cooperate with thekeys, or in place of the keys known forms of be employed.

In further reference to the operation of the press it may be stated that when two or more forms are used on the adjustable or cross line form can be registered and proved from the down line form, being located in the same relative position in the corner of the other compartment of the bed. When both forms are locked up and registered, the transfer roller is brought forward to pick up the superimposed 1mpression lines from the registered forms and is then carried backwardly to its starting position without being brought into contact with a printing element. The double bed can then be adjusted in the manner indicated in dotted lines in-Figure-l until all the superimposed impressions are on the transfer roller, after which the filled transfer roller can be lowered'into contact with a .printing element and-the objects collated on the transfer roller laid or transferred in one operation thereof 'on' a printing element. If more than two objects are to thus be collated on the transfer roller another ob'ect corresponding in position to the cross ine object in Figure 1 will be substituted for the object before occupying its place, and before a transfer has been made of anyof the theretofore collated matter from the transf latter. i r The transfer roller may be shifted totransfer the entire collation on a printing element in oneoperation of the latter roller. As many superimposed object forms as desired may be thus prepared and picked up by the transfer roller before fina printing or transfer impression operation of the I stood that the length of the parts of the printing element, a pr'oo dobule bed, the printing element beds, and the intervening spaces will be so proportioned to fix the positions to the effective surface of the rollers as of the rollers relative to the forms and plates for proper provin registering, and printing.

0 far as the structural details of the various mechanisms by which to'operate the proof and transfer rollers and by which to elevate and depress the rollers at the desired times, and otherwise, adapt the effective surfaces of the rollers to the forms and printing elements and by which to adjust the movable beds 17 and 78 are concerned, such details may be considerably varied. from vthose s own, said details being merely illustrative ratherthan limiting.. It is believed, however, that the combination of the proof and transfer rollersoperating on a single frame in connection with a movable or adjustable double printing form bed and with a bed or beds for supporting the printing elements to receive impressions from the transfer roller or rollers is novel, and such combination and i the general adaptation of the meansto effectuate said result are herein I claim as my invention: 0 1.
