This invention relates to improvements in preregistering' means for photo-composer printing plates.

In the art of makin press plates by photographic printing mac ines, commonly called photo-composers, it is now substantlally the universal practice to register, that is, accurately position and locate the image or subject on the negative with reference to the negative holder before the latter is attached to the photo-composing machine proper where it is attached in a known, definite, predetermined position with reference; tothe. movable carriage of the machine. Such preregistering of the images or subjects with reference to' the immediate holders must be done with great accuracy, particularly in color-printing, to insure that all the difierent color-separation rints 9f the same image oth positioned and located identicall on the several color-press plates. Even in the case of preparing a single colorpress plate, a similar degree of accuracy is necessary in order that the several prints or impressions on the press plate, whether of the same sub'ect repeated or of a number of differen't su jects, .will be in proper alignment and without visual overlapping or tilting.

The usual manner of efiecting' this prede termined register of the image or subject with respect-to its holder is by means of cross marks or lines on the negative plate or film, which marks are so located that if the lines comprising the same are extended across the. image or subject the extended lines will cross each other exactly at right angles at the center of the image, the said two lines being exactly parallel respectively to the usual longitudinal and lateral travel lines'of the negative-sup orting carriage on the photo-composer, w ereby the location and position of the image, when in printing position on the machine, may be accurately determined as by the use of scales-paralleling the longitudinal and transverse travel lines of the carriage. It J also occasionally happens in this art that'a I i v negative or 'SQIIGS of color-separation negatives will be found that do not have any reg:

ister means or marks thereon of any character, and in such cases'it has heretofore been extremely di'ificult to register such negatives, I

particularly in a color series.

One object of my invention is to provide an extremely accurate re istering means'for the images or subjects 0 negatives with respect to their negative holders, which means comprise relatively few parts comparative ly inexpensive to manufacture, easily manipulated, and by which negatives of different sizes mayl be handled, whether said ne atives are of t e rigid class type or flexib e film pe. Another objectofmy invention is to rovide registerin means for ne ative hol ers of that type w erein the hol er' is adapted to be positioned and located, both while in the registering means proper and in the photo-composer machine proper, b 'means confined to one side only of the holder. v Another object of my invention is to provide registering or preregistering means of the type indicated 1n the preceding paragraph, wherein the holder may be accurately adjusted with respect to the/registering de vices proper to compensate for difierences in over-all width of the negative holder. to the end that the horizontal center lines of the latter, regardless of size, will "always be in identical position to thus insure accurate location of the images or subject with reference to the composing machine proper when the holder is positioned thereon.

A' still further object of my, invention is I to provide means of the character hereinbefore indicated, wherein the image carried thereon, having a predeterminedknown posi-" tion and location, may be broughtinto relatively close or actual surface contact with the negative or printing plate to be registered. so as to thereby avoid the efl'ects of parallax and obtain the desired accurate register. H

' A more specific object of my invention is to provide registering means wherein is employed a registering 'frame having a register sheet or plate marked or scribed in such a manner as to indicate the two intersecting travel lines of the composing machine, which sheet or plate may be brought into operative,

preferably face-to-face, contact with the negative to be registered.

I Another specific object of my inventionis to provide an arrangement whereby negative or printing plates having none of the usualregister marks thereon. may be accurately registered Within or with respect'to their holders so that, when the holders are attached to the composing machines, said images will-occup'y a predetermined position and location. with respect to the machine.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

'In the drawings forming a part of this specification, Figure 1 is a front elevational view of a registering means embodying my shown in section, illustrating the means for adjusting the supporting bar on one of the frames. Figure 6 vis an enlarged detailed View, partly In section, illustrating more particularly the means for adjusting one of. the fastening or holding devices. Figures 7 is an elevational view of ,a modified form of the registering device proper. Figures 8 and!) are more or less diagrammatical views, illustrating the results of incorrectly and correctly po'sitionedand located negatives when multiple impressions therefrom are made on a press plate in those types of photo-compos ing machines where the press plates move in twodirections at right angles-to each other and relatively to a fixed negative holder. Figures 10 and 11 are views corresponding to Figures 8 and 9, respectively, illustrating the same features -forthose types of photo-composing machines where the negative holder moves relative to afixed press plate. Figure 12 is a plan view of a modified form of registering apparatus. Figure 13 is an enlarged, broken, sectional view, corresponding approximately to the line 1313 of Figure 12.. Figure 14 is a plan view of the floating bushing used in the construction of FiglireslQ and 13. Figure 15 is aside elevational view of the bushing shown in Figure 14. Figure 16 is a plan view, illustrating a still further modification of registeringdevice particularly adapted for flexible films. And Figure 17 is a transverse sectional view, corresponding substantially to the line 17- 17. of Fig:

- thus minimize shocks.

ure 16; but with sheets of rubber and steel applied.

- In said drawings and referring first to the construction illustrated in Figures 1 to 6, inclusive, the apparatus is shown as comprising an upstandin main frame having vertical uprights 20 -20, upper and lower cross connecting members 21 and 22, the latter having extensions 121 and 122, respectively, at each sideof-the vertical uprights. Said extensions are formed with hinge butts 23 at.

one side and hinge butts 24.at the other side of the main frame and to which are pivotally connected an image frame A and a registering frame proper B, respectively, the connection being effected by heavy pivot bars or rods 25 and 26. Preferably coiled springs 27 are interposed between the stationary parts and the pivot rods in such manner as to be tensioned when the frames are swung to either full open or full closed position to The main frame also preferably has a lower crossbar 28 havinga shelf 29 to facilitate handling of the holders 1 and to provide a temporary rest therefor when placing the. same on the apparatus. The extensions 121 and 122 are further preferably provided with outstanding lugs 30-30 which act as stops to limit the outward swinging of the frames A and B. With the construction 'so far described, it is evident that the frames A and B are each adapted to be swung over the centrally disposed main frame of the apparatus and each. of said [frames A and B will always bear a definite predetermined relation with respect thereto.

When eitherframe A or B is swung to such operative position, it is stopped or limited by the cooperable. en aging extensions 31 and 131 on the swing spectively.

As hereinbefore indicated, the apparatus is adapted to handle negative. holders which are in turn adapted for attachment to the photo-composing machine along one edge. only of the holder, and to that end the apparatus includes a vertic'allymovable mono-v rail or attaching member shown best in Figures 1, 3 and 4. As shown, said monorail, comprises 'a main .horizontally extending rame and main frame rebar 32 on the front side of the uprights20.w

-- At each end ofthe bar 32' there is provided a heavy block 33, thelatter having inwardlye-xtended' sections 34: which engage behind.

the uprights 20'and thus adapt the cross bar 32 for vertical sliding movement withreference to the uprights. Fixedly associated with each of the uprights 20 is a rack bar 340, with which are adapted toenga e pinions 35 secured to atransversely xten ing shaft 36 which is journaled at its ends in depending bearings 37 37 integral or rigid with the blocks 33. At one end, the shaft 36 carries a clutch element 38 with whichis'adapted .tocooperate a corresponding clutch element 39 a on the hub of a hand lever 41 slidabl mounted on an extension of the shaft. y rotating the shaft 36, it is evident that the monora1l or cross bar 32 will be raised or lowered, due to the cooperative engagement of the pinions 35 and racks 340.

On the rear side of each of the uprights 20 is provided an accurate gauging rack and each of which consists of a plurality of blocks 42 and 43 of different lengths, the blocks 43 bein alternated with the blocks 42, as shown in igure 3; Said blocks 42 and 43 are of extremely accurate dimensions and preferably J ohansson blocks and of'half inch width. The blocks are held in assembled position by suitable means, such as the set screws 44 and a lower clamping screw 45.

Cooperable with each of the block racks just described and carried at each end of the monorail 32 are corresponding blocks 450, also preferably of the Johansson type, which blocks 450 are accurately spaced to' interfit between the blocks 42, The blocks 450 are carried by a slide 46 horizontally slidablv mounted within the corresponding end block 33 of the monorail, said slide 46 being provided with a short rack .47 witlrwhich meshes a pinion 48 attached to a short vertical shaft 49 j ournalled in the corresponding end block 33. Each shaft 49 carries also an additional pinion 50 with which cooperate slidable racks 51 and 52, respectively. At their inner adj acent ends, the, racks 51' and 52 are slidably mounted in a housing 53 secured to the monorail 32 and within which are journalled two meshing pinions 5454, each of the pinions 54 also meshing with racks 151 and 152, respectively. At one side of the machine, and preferably the side at which is located the operating lever 41', the vertical shaft 49 has attached thereto a second operating lever 55, so that upon rotation ofthe lever 55 the corresponding shaft 49 will be rotated,-thus directly actuating the corresponding gauge blocks 450 at that end of the machine-and indirectly, through therack bar 51, pinions 54, rack bar 52 and shaft 49, operating the gauge-blocks 450 at the opposite side of the machine, With the arrangement described. the monorail is given a rough adjustment vertically by manipulating the lever 41 and therposition of the monorail is'then accurately gauged by means of theinterfitting blocks of the block rack and engaging blocks 450 in themanner above described. 3'

To provide for attaching a negative holder, the monorail 32. on the front side thereof, has a pair of dowel pins 56-56 projecting'outwardly beyond bushings 15.6-156W,Said

dowels areiaccurately spaced and located to correspond exactly with cooper-able dowel holes in, oneside of the negative holders. The bushings 156 hold the negative holders outwardly spaced from the monorail 32 so ployed on those negative holders of the vacuum type do not become'fouled during the regbe backed to minimize tendency to tilt by a suitable backing frame which, as shown, comprises a crossbar 57 havinga pair of vertically extending arms 58 secured thereto. The vertical arms 58 are fastened to the upper cross connecting member 21 and the horizontal bar 57 is attached to the vertical uprights 20. zontalbar 57 has slidably mounted thereon cross heads 59 which may be brought up against the side edges of the holder C and locked in adjusted position by set screws 60.

The holder C, shown in Figure 1, is gener aily of that type shown in my pending application Serial No. 295,683, filed July 27, 1928, and. as there shown, comprises an outer main holder proper 61, a gap frame 62 and the glass negative proper 63. The latter is shown as provided with register marks in the form of crosses 64-65. there being two of the former in vertical alignment at thecenter and two of the latter inhorizontal alignment at the horizontal center. A large cross is indicated at 66, which indicates conventionally the image or subject. The glass negative is adapted to be held in adjusted registered position by the clamps 67.

Referring now 'to the primary registering device proper on the frame B, the same com-v To further steady the holder C, the horiprises a. horizontally disposed guide bar 68 and a vertical guide bar 69. both rigid-with the rectangular frame B. Slidably mounted on the bar 68 are apair of blocks 70,- each of' which carries a pinion (not shown) cooperable with a. rack 71, the pinion beingoperated through the knurled wheel 72 whereby the are so positioned that the two reticules car;

ried by the horizontal bar 68 define or deter- .2 mine av horizontal; line which coincides with -c11e.of-the travellines of the carriage of the photo-composing machine and is so located that said horizontal linewill bisect. horizon- 55 that the rubber sealing gaskets which are emtally, a holder C when the latter is improper position on the registering apparatus. Similarly, the reticule 73 carried by the vertical guide bar-'69 moves in a vertical line exactly at right angles to the line ofmovement of V the other reticules 7 3,'that is, exactly in ac- 5 sponding reticules, as shown in Figure 1'.

As will-be understood. said scribers are normally retracted but may be .adjusted perpendicular to the plane oft he frame B so as to be brought into use for the purpose hereinafter described. For a more detailed description of the blocks 70, reticules. scribers and adj usting neans. reference may be had to my prior Patent 1.452.078. granted April 17. 1923.

Register of a negative 63 is obtained in the following manner when using the register frame B. The holder C is attached to the monorail 32 by the dowel pin arrangement. it being understood that the monorail is in the proper horizontal position corresponding to the size of holder employed. The holder C will carry the negative 63 but, as will be understood, the latter is not at first in registered position. The frame B is then swung over the negative and the reticu les73 adjusted through the wheels 7 4 so as to bring the reticules closely adjacent and in substantially face-to-face contact with the surface of the negative 63. Thereupon. the reticules are adjusted back and'forth on their respective guide, bars and simultaneously the negative 63 is manipulated by hand (the clamps 67 having first been loosened for this purpose) until the two horizontal cross marks 65 of the negative are directly positioned beneath the two reti'cules 73 on,the guide bars 68 and the upper' vertical cross 64 brought directly un-' der the reticule 73 carried by the vertical guide bar 69. When the negative has thus been adjusted to have the cross marks of the negative perfectly coincide. thenegative'is then locked or clamped in this adjusted posi; tion. As will be understood. the cross or register marks 64 and 65 will be placed on the negative so 'as to horizontally and vertically bisect the image or subject. When thus adjusted. it is evident'that' the vertical and horizontal center lines of the image on the negative, regardless of irregularities in the negative. will coincide exactly with the. vertical and horizontal-median lines of the holder proper C and, hence, when the holder C is transferred to the composing machine and attached'thereto in proper position by the same dowel'pin arrangement, the image or subject will be positioned properly with known.

In this connection, reference may be had respectto the press plate and the center of the image will be definitely and'accurately to Figures 8'to 11, inclusive, which illustrate,

conventionally, the results of-p roper register and misregister. In Figure 8, a press plate 7 5 is shown attached to a holder 76 which is adapted for both vertical andhorizontal movement, as customaryon'some photo-composers. 166 indicates conventionally the reproduction or impression from a correspondi mg image 66 on the negative where the latter has been improperly positioned, that is, its horizontal and vertical center lines havenotbeen registered to coincide exactly with the two horizontal and vertical 'travel lines of the press plate. As'clear from Figure 8, the reproduced images on the press plate will be staggered or cooked and misregistered, even though the centers of the negatives are accurately placed. In color-printing, where several different color press plates are required,

the effects of misregister willbe evident, particularly when it is considered that another negative of the same series may be misregistered a similar amount but tilted in the opposite direction.

In Figure 9, the reproduced images 266 are shown. where the negative has been accurately registered both as to position and location. and in this instance all of the reproductions are perfectly true and square and there is no possibility of overlapping of the images on the press plate.

Figures 10 and 11 illustrate the same features, except that in this instance the carrier 77 for the negative holder C is itself uni-- versallv adjustable with respect tothe press plate 175. The same results will be obtained when misregister occurs. as shown bv thereproduced images. 366 in the case of Figure 10 and proper squared positioning of the reproductions as shown at 466 in Figure 11. As will be understood, the degree of misregister in Figures 8 and 10 has been exaggerated to more clearly illustrate the results thereof, but, in commercial practice. the misregister I of more than three-thousandths of an inch'is sufficient in most instances to cause rejection of a printed job in color work.

Referring to the modification shown in Figure 7', instead of using adjustable reticules. a single registering element 7 8 may be employed, fixedly attached to the frame B in such position that the scribed horizontal line 79 will coincide with One travel line of the machine and the other wertical scribed line 80 will coincide with the other travel line of the composing machine. The member 78 will be made of transparent material so that when the frame B is swung t'o operative position over the negative the operator may look therethrough and thereby bring the register a knurled head 99.

5 thereon. To register negatives of this character, I employ the image frame A. The latter is also of rectangular construction, similar to the frame B, and is provided with a cross bar 81. The latter, as best shown i- Figure 5, is adapted to be adjusted vertically with extreme accuracy by the following arrangement.

Slidably mounted on each of the vertical arms 82 and 83 of the frame A are two cross heads or slides 84 and 85 on the arm 82 and two cross heads or slides 86 and 87 on the arm 83. The right-hand end of the bar 81, as viewed in Figure 5, is fixedly attached to the crosshead 84 by suitable means such as the screw 88, The 0 osite end of the cross bar is horizontally, s i ably, adjustably mounted within a housin 89 on the cross head 86, the bar being provi ed with an elongated slot 90 for this pur ose and a'set screw 91 extending therethroug for locking it in adjusted position. Each of the cross heads 85 and 87 are of like construction and the same aie vertically slidable on the arms 82-and 83. Heads 85 and 87 are ada ted .to be clamped in ad- 'usted position by urled set'screws 92-92. ach of said cross heads 85 "and 87 is pro,- vided with an offset nut 93' in which isthreaded a vertically extendin screw 94 having swiveled connection in a ug 95 with the corresponding cross head 84 or 86. Each'of the latter in turn is provided with a set screw 96. With this arrangement, upon loosening the set screws 92 and 96, the bar 81 may be. adjusted roughly to the horizontal position whereu on the set screws 92 are enga ed, thus locking the cross heads 85 and 87.. he finer adjustment is then efi'ected through the adjustin screws 94 and when the proper position 0 the cross bar 81 is obtained the cross heads 84 and 86 are then locked by the set screws 96. Slidably mounted on the cross bar 81 are two similar cross heads 97, each of which has a geared connection with a rack 98 on the cross bar, as shown in Fi re 1. Adjustment is effected back and fort by a suitable pinion and shaft arran ement, the latter havin glidably mounted in eac cross head 97, in a direction perpendicular to the plane of the frame A is a bar 100, the adjustment back and forth being-effected by suitable rack and inion arrangement 0 erated through the urled head 101. Rigid with each bar 100 is an inward laterally extended arm 102 (see Figure 6) which carries ,an attaching screw 103 adapted to engage with and secure a holding frame 104. T e cross heads 97 are adapted to be locked in ad justed position by suitable set screws 105.

In the instance shown, the holder 104 is adapted for the carrying of a flexible film 107 suitably attached around its edges by means of clam ing and stretching jaws 108 in turn mounte on a sub-holder 109, such as shown in my application hereinbefore referred to. To obtain registervof a series of negatives having no register marks, the following. procedure is adopted: A holder (1 is taken and in it is clamped a plate similar to the negative 63 shown in Figure 1. With the plate in position in the holder and the latter mo'unt-' ed on the main frame, the register frame 1s swung over 1t and then two marks are obviously these two scribed-lines will locate the center on the plate with reference to the holder C. Next, a positive impression of the scribed on the plate by the scribers 173, and

unmarked negative to be registered is mounted on the holder 104-carried by the swin frame A, this positive impression being pre erably applied to the flexible film 107 carried by the holder 104,'as previously described.

8 The frameA is then swung'over the holder C having the scribed glassplate, and the holder 104, carrying the filmv with the posi tive impression of the image,- isthen' ad'-" I justed relative to'the scribedplate until {the prea of the image is quartered with reference 0 the two scribed lines of the plate, that is, the posltive impression of the image will be acil usted-as accura tely as possible under the imageimcpression is centered and properly .positione Thereupon, after swinging the frameA back to inoperative position, the scribed plate is removed fromthe holder C and one of the unmarked negatives to be registered is substituted therefor. The swing frame A is then swung over the holder 0 to operative position and the unmarked negative in the hglder C adjusted within the latter until the image of the negative coincides in position and location with-the posi- -tive impression of the image carried by the swin frame It is thus evident that all of the p iates of a series of unmarked negatives can be registered withinthe holder C so that the positions and'locations ofall of the series of images will coincide. In the event the negatives are to be reused at any time in the future, each of the same will preferably be gme'nt' of the operator until the positive scribed with suitable marksout'side of the area of the image by using the scribers 17 3, this marking being done after each negative has been registered with reference to the positive film.

L" In positioning the positive impression film Ordinaril the holder 104 will be provided with a series of openings for attachment by the screws 103and the attachment will be -made to the nearest hole which will centerthe holder ,104 vertically. The more accurate and. final adjustmentvertically of the holder 104 .is accomplished. by the micrometer screws 94'94. Theholder 104 is. adjusted laterally when registering with the scribed plateby shifting the cross heads 97 back and i forthuntil the desiredposition is reached.

-- Referring next to the modification illustrated in Figures 12 to 15,in clusive, 120 represents the negative to be registered, the same being secured to its immediate holder 121 by suitable clamps 1220. The said holder 121 is centered with respect to the negative frame 123 by twovor more dowels 124 and the proper level of the negative isobtained by adjusting screws 125.. The negative frame 123 .is-of the vacuum .type and has an outer marginal frame 1260f hollow rectangular construction so that the vacuum maybe efi'ected entirely. around the negatives,"openin 127 leading from the assage .128 at intervals therearound. A ru ber sealing'strip 129 extends around the negative frame and an in- I is not intended to beadjusted for registra ner rubber sealing strip 130 is employed to effect the seal substantially the same as shown in Figures12. and 13 of my said-pending application SerialfNo. 295,683. In the present form, however,.the negative proper I tion purposes with referencetotheaiegative frame 123, the registration bein hccom plished in the manner about toube escribe'd. In the present construction, the negative I frame 123 is adapted to be accuratelypositioned on an auxilia dowel pins 132. -T e aux liary frame 131 is 'in turn provided alon one edge thereof with two adjustable bush ng devices. Each of these adjustable bushin prises a bushing proper 133 avi a dowel ole therein134. Each bushing 1 3 has an.

upper section 1350f enlarged diameter seat in'g upon the auxiliary frame 131 and a lowersection 136 of reduced diameterpositioned' loosely within an opening 137 of the frame.

131. The bushing 133 is held assembled'with the auxiliary frame 131 by a housing'plate 138 secured to the auxlliary frame as by screws 139 at diametrically opposite points.

thereon. At each end-of the housing plate 138, th'elatter is slotted, as indicated at 140, so as to provide a resilient section 141 on the to Extending through each ofthe slotted an s of the housingrplateand threaded within the auxiliary screw 142. The bushings 133 are adapted to cooperate with the two dowel pins 143 carried by-the monorail of the registering apparatus, a portion of said monorail 32bein'g shown in section in-Figure 13.

Re stration of the negative iseflectedjn the following manner: The negative is first .clampedin its immediate holder 121 and the; latter then mounted on the ;negative frameroper 123' and adjusted to the proper level. 0 negative is located by eye as nearly cenframe 131 by means of devices comame 131 is a clampingtral as possible. This assembly is then,

mounted on the auxiliary frame 131 by means of the dowel arrangement 132 above described.

The assembly ofl'the auxiliary frame and negative frame is then applied to the mono-. rail, the bushings 133 being loosened so as to permit the bushings to be placed on the dowel pins 1430f themonorail. With the parts in the registering apparatus thus mounted, t he register frame proper is swung into operative position and then the entire assembly of auxiliary frame 131 and negative frame. 123

with the negative 120- clamped thereon is shifted and adjusted with reference to the negative coincide with the-reticules, ,aswill be understood. When the image on the negative has thus been roperly registered with 'the reticules, the c amping screws 142 are tightened, thus firmly locking the bushings k 133 with reference to the auxiliary frame 131 and, of course, with reference'to the negative.

frame.- In this construction the. register frame 144, preferably bf rectangular outline to conform to the negative holders, has fixedly secured thereto a register plate 148, the upper, surface of which is flush with the upper surface of'the frame. Said plate 148 is provided with a master image or register mark in the form of a large cross comprisedof the vertical line 149 and horizontal line 150. Said lines 149 and 150 intersect exactly at right.

reticules- 73 until the register marks of thel so ister frame it will be accurately positioned and located in a predetermined manner with reference to the master image or re ister marks 149 and 150. The film frame 14 has a flexible'film 153 tacked or otherwise secured thereto in a taut condition, said film frame being clamped to the holder 146 by any suitable means. such as the plurality of adjustable clamps 154 located around the sides thereof.

In this manner,the film, after attached to its.

a definite relation with theframe, maintains holder 146.

The holder .146 is adjustable within the frame 145'and is' adapted tobe clamped in adjusted position by means of a plurality of adjustable, clamping jaws 155 operated by screws 561. Where the film holder is adapted to be used with a vacuum system, the frame 145 will be provided with a rubber sealing strip 157 around the margins thereof, and on the other'face will be provided with a rubber sheet 158 held in place by a thin plate 159 of steel or other suitable material.

In registering a film with the apparatus of this modification, the frame 145 is assembled with the frame 144 in the manner above described. The holder 146 is then shifted or adjusted until the register cross marks 160-160 on the film are brought into proper register with the master image or master register mark 14 9-150, whereupon the clamps 155 are tightened and the arts locked. In this connection it will be an erstood that the holder 145146 is adapted tobe mounted on aphoto-composer having dowel pins corresponding to those referenced 151 on the register frame 144.

Although I have herein shown and described what I now consider the preferred manner of carryin out my invention, the same is by way of illustration only, and all changes and modifications are contemplated that come within the scope of the claims appended hereto.
