To all whom it may concern:

Be it known that I, LOUIS SMITH, a citizen of the United States, and a resident of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements in Proof and Transfer Presses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference bein had to the ac companying drawings, an to the characters of re erenc'e marked thereon, which form a part of this specification.

This lnvention relates to novel proof and transfer presses for taking proofs from forms suitably locked on a bed for proving and registering the form and therea r, without removing the forms from the bed after the same is in register, transferring the impressions from the forms direct on printing lates for lithographic or ofiset presses. he press is designed for making either positive or no ative transfer printing plates or elements or lithograph or offset presses from zinc, aluminum, stone, rules, type, or cuts in one operation, in one or more colors. One or more forms can be made on a printing plate by direct transfer from rules, type, or cuts, to zinc plate, aluminum, or stone.

The purpose of the invention is to rovide a novel construction, wherein a proo f transfer roller may 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 u and registered by running the proof ro ler thereover, and thereafter the impressions from the forms directly transferred therefrom by a transfer roller or rollers to a printingelement such as zinc printing plates, lithograph work or ofiset work, thus providing in one simple press means for successivelyl proving and transferrin the'work, whic may be employed for lit ograph work only or for ofi'set work only, and which may; be used also as a proving press for composing room. I

Another object of the invention is to provide a novel press of this character wherein the bed that supports the printing forms may be adjusted with respect to the proof roller and to the transfer roller or rollers, so as to adjust the press to forms of different sizes locked on the bed. Such adjustment of the bed may be efiected either in a direction and a.

, provide aluminum or stone for arallel to the axes of the proof or transer rollers or in a direction transverse thereon, as the adjustment may be in both directions.

Another object of the invention is to provide novel means for s0 adjusting the bed.

A further object of the invention is to provide means for operating the rollers, constructed and cooperating with means for elevating the rollers above the forms and printing elements so that said rollers may be moved longitudinally of the bed without contact with certain of the forms or plates 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 for supporting 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 printin elements at certain parts of the travel of t e rollers.

Another object of the invention is to rovide a novel arrangement of transfer ro lers whereby the impression from the printing forms may be either transmitted directly to a printing plate, stone, or the like, as a negative impression or directly transmitted to a second roller for direct positive transfor an offset press.

the invention is to a support in a device of this character for such printing plates so arran ed as to permit the plates to be shifted so t at the required number of transfers ma be made on the transfer roller and trans erred to the printing plates.

Other objects of the invention are to imfer to a printin plate A further obect of prove and simplify proof and transfer presses, and the invention consists in" the combination and arrangement of the parts shown in the drawings and described in the,

specification, and'is pointed out in the appended-claims.

In the drawings Figure 1 is a fan view of a proof and transfer press em odying my invention.

Fig. 2 is an enlarged plan. view of the front end of the press with parts broken awa r Fig. 3 is an enlarged rear end of the press with parts broken away.

Fig. 7 is an enlarged side view of the rear end of the machine.

' Fig. 8 is a longitudinal section thereof, taken on the line 88 of Fig. 1.

Fig. 9 is a cross section on the line 9-9 of Fi 2. .i 10 is a cross section on the line 10-1O of Fig. 3. V

The frame of the machine may be made of any suitable or convenient shape to properl support the elements of the machine and their bearings and is shown as comprising a horizontal platform supported on legs or standards. It has an extension 16 for a purpose to be hereinafter described. $upported on said frame is a movable or ad uStable printing form supporting bed 17 and a fixed bed 65 to support printing elements 66.

The movable or adjustable bed, as herein shown, is made of a width substantially equal to the width of the frame and of a length to extend throughout the principal distance between the roof roller and the fixed bed 65. .The printing plate supportin bed 65 is raised above the level o the bed 17 so that the latter in its lon 'tudina] adjustment may pass partly beneat the bed 65, as indicated in dotted lines in Fig. 1, and for a purpose hereinafter described. The frame 15 is also provided at one end with a transverse extension 76 to en port an adjustable bed 78 for printing ates 7 7 herelnafter described. The be 17 may be termed a double bed inthat it is arranged to support two or more formswhich are adapted to be registered to produce the ultimate composition.

For convenience and certainty, the forms supported on the bed 17, are herein termed prmtin forms; the plates 66 supported on the fixe bed 65 are termed negative rinting elements, and the plates 77 supported on the ad'ustable bed 78 are termed positive printing elements. These terms are not however, intended as limitin terms but are descriptive of the present 1 lustration of the invention.

Said bed 17 supports frame or chases 18 in which are locked in any,suitable manner the forms 18' best shown in Fig. 1. The particular forms shown in Fig. I may be the down and cross line forms tat are composed in proper register for'printing 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 acmay be associate cordance with the aforesaid method, may bear in addition to the down and cross lines, such printing as may be desired. As shown in Fig. 1, the forms 18 are of dimensions to occupy allotted rectan lar s aces 18 on the bed, and, as herein 3 own, t e transverse width of each space is equal to one-half the len h of the roof and transfer rollers. ssuming t at proofs are to be made of down and cross lines of a cross ruled form, after proofs have been taken from the full line forms shown in Fig. 1 on one-half of the proof roller, the bed supporting said forms may be shifted so that t e forms noon the positions indicated in dotted lines in '*1 1 and the same proofs taken on the other half 'of the proof roller. I

If desired, however, other forms, such as Slates, rules, type, or cuts of the same or ifierent colors be locked on the bed to constitute smaller forms, in which event it is desirable to adjust the movable bed both laterally and longitudinally of the frame so as to bring the forms in proper registration with desired longitudinal and circumferential areas of the proof and transfer rollers.

The means herein shown for laterally adjusting the movable bed comprises -a threaded shaft 20 which is rotatably mounted in a suitable bearing 20 on the frame and is threaded throu h a nut 21 that depends from the bed 'ig. 9). Said shaft is-provided with a hand wheel 22 and a graduated dial; cooperating ointer 22' (Figs. 2 and 5) with said shaft so as to facilitate the registration of the forms relatively to the proof and transfer roller. The extension 16 of the frame 15 is provided to support the bed 17 when the latter is adjusted to occupy the position indicated by the dotted lines in Fig. 1.

25 designates'the proof roller which is located at t e forward end of the frame. It is supported on a. shaft 25' that is'rotatively mounted in bearings carried by bearers 40 which are in turn supported on tracks 41, 41' the latterfixed relatively to the frame and the former vertically adjustable, as hereinafter described. 26, 26 desi nate spur giars which are fixed to said sha t 25' or to t e roller 25 and mesh with the upwardly facl tgg teeth of

racks

27, 27 that are suppo on the frame 15 at the sides thereof whereby, on rotation of the roof roller, the

.latter is caused to rotate on its axis and-also be carried bodily lengthwise of theadustable bed. The said proof roller is re.- tatedbn its Taxis and caused to move along the glate by means of a crank 28 fixed to the sha 25'. The track sections 41 are. adepted to be raised in any suitable or preferred manner to lift the proof roller out of contact with the forms or certain of them, as v will hereinafter more fully appear. 29 designates a group of inking rollers of any to predetermined peripheral areas of the proof roller comprise a rotative shaft 32 that is disposed transversilly of thefframe and is mounted in sui 32' thereon. Said shaft 32 carries near "'1' end pinions 83 which are adapted to mesh with the downwardly facing teeth of racks 34 suitably fixed to the bed 17. The shaft 32 is provided at one end with a hand wheel 35 by whichit is rotated, and a graduated dial 35 and a 'coiiperating pointer may be associated with the shaft to measure the rotations of the shaft and thereby facilitate registration of the forms relatively to the" proof and transfer rollers. I

Through the coaction of tlfe adjusting shaft 20, and nut 21, on the one hand, and the shaft 32 and the pinions 33 and racks 34, on the other hand, it will be observed that the bed 17 may be shifted either laterally or longitudinally of the frame to efiect'desired registration. of the forms relativelglto the proof and transfer rollers and to a just the press to forms 'of different sizes The threads of the-shaft 20 and the teethof the pinion 33 and racks 34 will be made of such pitch as to givea desired delicacy of adjustment of the bed in either directlon, Endthe dials 22 and 35 are graduated to indicate such adjustments; It will be understood that the ppinters'of said dialsare geii-ed in any suite is manner to the

shafts

20 and 32 to cause the pointers to swee over the dials as said shafts are turned to just the 'bed.

The shoes vor bearers 40, in which the shaft 25' of the proofroller 1s mounteflbear upon the fixed tracks 41' of the frame at the front end of the press when the proof roller is in its inoperative or' retracted position and when stai roller is moved over the forms 18 said bearers 40 are supported by the sectional tracks 41. When the forms are of such size as to occupy less area than all of the bed, or when proving multi-color forms on'the bed, it will 0 necessary in sortie parts of the travel of the proof roller, over the form to lift the same away from or out of contact with certain of the forms. Such lifting of the proof roller'may be effected by raising the sectional tracks 41 and said tracks may be raised in any suitable or approved manner. for raising the tracks are made as follows: The said track sections are provided at their ends and on their under sides with shallow cai'n faces adapted to be engaged by the inner arms of levers 43 that are pivoted at 44 to the machine frame. When the levers 43 are in their outstanding positions,

" If the The means herein shown or normal to the sides of' the frame, as shown in Fig. 3, the arms 45 are engaged with said cams and serve to raise the tracks to positions indicated in Figs. 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 swun at oblique angles to the positions indicate? in Figs. 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.

designates a transfer roller, the shaft 51 of which is mounted in suitable bearings carried by bearers 56 that are adapted to bear on the fixed tracks 41' of the frame or upon the sectional raisable and lowerable track sections 41. The shaft 51 of said transfer roller is adapted to be rotated on its axis through the medium of a hand crank 52 attached to the said shaft. At the ends of the transfer roller are spur gears 53 which mesh with the upwardly facjn teeth of the rack 27. above referred to, w ereby when the crank 52 is turned, and there through the transfer roller 50, the engagement of said gears 53 with the tracks 27 causes the transfer 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 said transfer roller may be thereafter moved backwardly over the bed 17 and to the bed to transfer the impressions received thereby on the printing elements 66 suported on the fixed bed. When said trans er roller 50 is being moved forwardly over the fixed bed 65, the track sections 41 are elevated to lift said roller out of contact with the printing element 66 and when the roller is returned to said printing element after receiving the transfer from the forms 18', the track sections are depressed to cause the impression received by the transfer roller to be transferred to said printing element. Also the track sections 41 may be thus raised to lift the transfer roller out of contact with any one of the forms 18' not to be transferred in any particular operation of the machine.

plates 66 on the bed 65 are to be used as lithograph plates on a lithograph press, the transfer of the forms on said plate or element will be negative or the same as shown on the forms 18', and said plates 7 after receiving the transfer from the roll 50 are removed to be prepared for the lithograph press and used as printing plates in the usual way.

At times itis desirable to move the transfer roller 50 bodily lengthwise of the bed 5 bed without rotating it on its axis is shown in Fig. 4. As therein shown, the shaft 51 of the transfer roller is grooved to receive

keys

60, 60 having hand pieces 61 exposed at the ends of the shaft, whereby the keys in may be shifted in the keyway. The heads of the transfer roller 50 are provided with keyways 63 and the spur gears 53 are also provided with keyways 62. When the broad inner ends of the keys 60 are engaged partially in the keyways 62 of the spur gear and partially in the keyways 63 of the transfer roller, said transfer roller is locked to the gears 53 so that when the shaft 51 is rotated, through application of power to the crank shaft 42, the transfer roller will be 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 27. When the

keys

60, 60 are shifted so that its broader inner ends lie wholly within the keyways 63 of the spur gears 53, said gears may rotate with the shaft 51, without, however, transmitting rotation to the transfer roller 50. In the latter so 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. The keys may be connected in any suitable manner for mutual operation, as for instance in the manner shown in Flg. 4. a,

When it' be desired to transfer the impressions'from the transfer roller 50 for positive impression to printing elements for 40 ofi'set press work, the impression from the transfer roller 50 is transferred directly to a second transfer roller 70 that is so mounted on the frame that said

transfer rollers

50 and 70 may be geared together to rotate in peripheral contact with each other and at equal speed and thereby transfer the impression. from one roller to the other.

The said transfer roller 70 is mounted on a shaft 71 which is rotativel supported on and is carried by bearers 71 that are supported directly on'the fixed tracks 41' of the frame. In order to cause the

transfer rollers

50 and 70 to be rotated in contact with each other and,at equal peripheral speeds, said rollers are provided at their ends with meshing gears 72, as best shown .in Fig. 3. The shaft 71 of the transfer roller 70 is provided with a crank 73 by which the latter roller is turned on its axis and, through coaction of spur gears 74, '74:

at the ends thereof with the racks 27 before described, said transfer roller may be caused to be moved bodily over and in contact with the printing element 77 to trans- 66 fer the impression received from the roller length 0 50to the positive printing elements for off set work.

When the

transfer rollers

50, 70 are to be rotated in peripheral contact with each other to transfer. an impression from one to the other, broad, iiiner ends of the ke s 60, 60 of the transfer roller 50 may e forced inwardly wholly into the keyways 63 of the transfer roller 50, whereby said roller is released from the spur gear 53 so that the roller may be rotated on its axis without, however, causing said roller to move bodily relatively to the frame. The transfer roller 70 may be likewise provided with control- 'ling keys 7 5 by which said latter roller may mary transfer roller 50 to the secon ary transfer roller 70, and the impression thereafter transferred from the latter roller to the printing element 77. i

The bed 78 is adjustable transversely of the frame 15 so that impressions may be transferredtoa number of printing elemlents 1717 whose a ate length is reater t an t e fiis ransfer roller Such adjustment of the bed 78 may be effected by providin the bed with downwardly facing racks 80 igs. 3 and 7) which are adapted to be engaged by pinions 81 that are fixed to a rotative shaft 82 disposed transversely of the frame 7 6 and mounted in suitable bearings therein, and provided at one end with a hand cran In the operation of the machine, the proof roller will turnon its axis during the time it is being moved bodil rearwardly over the forms to receive roo impressions there from, and will be re eased from its gears so as to be carried bodily forwardly over the forms without turningon its axis, said proof roller returning to its normal or inoperative position while the interrupted or cutaway portion thereof faces downwardly. It will also be understood that the transfer roller 50 will be rotated on its axis when traveling forwardly over the printing forms 18 to receive the impressions therefrom, and that when traveling backwa-rdly over the movable and fixed

beds

17 and 65, respectively, it will be released from its gears so as not to turn on its axis, and during its return movement the cut away or interrupted ortion thereof will face downwardly. So li ewise, the secondary transfer roller 70 will turn on its axis when movin rearwardly over the printing element 77 ut will be disengaged from its gears and return forwardly to its inoperative position without rotating on its axis. a

shown for releasing the gears from the proof and transferrollers are merely illustrative as one form of such means, but it will be understood that any preferred or known form for. controlling the movement of the rollers to cause them to rotate when traveling in certain directions and to hold them from rotation when traveling in other directions may In event that the key means herein shown be employed, the frame may be provide with any suitable cams to cooperate with the keys, or in place of the keys known forms of ratchet release and co-acting projections on the frame may be employed.

So 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 'by which to adjust the

movable beds

17 and 78 are concerned, such details may be considerably varied from those shown, said details bein merely illustrative rather than limiting. t is believed, however, that the combination of the proof and transfer rollers operating on a single frame in connection with a movable or adjustable printing form bed and with a bed or beds for supporting the printing elements to receive the impressions from the transfer rollers is novel and such combination and the general adaptation of the means to effectuate said combination are herein broadly claimed.
