I Thisinvention relates to improvements in commercial photographic printing apparatus and more particularly to the means used in securing a variety of plates in predetermined relative positions within frames subject to transference to a machine for the printing operation.

The word plate is used broadlyto includ both positive and negative elements, the term negative referring to either a rigid or flexible plate, film or the like, made of any transparent or translucent material, as glass, celluloid or similar substance, paper'or textile fabrics treated to permit the passage of light, and bearing images or legends, inscribed manually or mechanically, or deposited photographically, ofv any subject matter, or having objects attached in a manner to be reproduced by photo-printing.

A positive is to be construed as a receptive element of corresponding nature, sensitized to receive a photographic image from a negative held in juxtaposition and subjected to actinic light.

One of the objects of the invention is to provide a frame having distinct and wholly inde- 25 pendent portions, each suited to receive a separate negative bearing registering marks and having means whereby the portions of the frame are relatively movable, in the same plane, both rectilinearly and transversely, that is vertically and horizontally with respect to an upright machine, and also angularly, whereby the register marks on each portion may be brought into absolute correspondence with register marks fixed on amaster frame superposed on portions of the negative carrying frame.

A further feature is in the provision of means for transferring the negative frame to a holder having connection with asuction means for producing a partial vacuum and provided with a marginal seal, the holder and irame being transferable as a unit to a registration plate having means for adjusting the unit in accordance with marks fixed upon it and thereafter held fixedly by clamp dowel engaging arms, carried by the unit, so that the unit may be placed in exact correspondence upon dowels on the face of a photo-printing machine.

Other objects, such as direct and positive shown in the accompanying drawings, constituting a material part of this disclosure, and in which:

Figure l is a top planview of a two part plate holder frame provided with means for adjusting one part relative to the other, both parts having plate receiving recesses, and means for confining plates therein, each plate being provided with registry marks.

Figure 2 is a similar view of a master frame having clamping means to engage the plate holder frame when superposed, and provided with fixed registry lines to which the parts of the plate holder are adjusted. i

Figure 3 is a plan view of, a holder apertured in conformity with the openings in the plate holder frame, part of one of which is shown as seated on a sealing blanket resting onthe holder which is provided with clamping means and extending adjustable arms. 5

- Figure 4 is a similar plan view of the same parts as disposed on a transfer plate having means for adjusting the frame and holder to agree with marks arranged in known relation to a photoprinting machine provided with dowels to engage openings in the holder armswhich are clamped when registration has been effected. 1

Figure 5 is an enlarged sectional View of the frame adjusting means, the section being taken online 55 of Fig. 1.

Figure 6 is a similar fragmentary sectional view takenon line 6-6 of Fig. 3.

Figure '1 is a view similar to Fig. 1 but showing yielding blankets interposed between the frame parts and a supporting plate on which they are seated.

Figure 8 is a view showing the parts indicated in Fig. '7 as disposed upon a holder shown in,

Fig. 3.

Figure 9 is a plan view of a device as seen in Fig. 8 but showing a modified plate adjusting, means.

Figure 10 is a similar view of the same parts as mounted on a transfer plate. Y

Figure 11 is an enlarged cross sectional View taken through one of the non-metallic clamps as disposed within the confines of a sealing device.

The devices shownin either Figs. 1 and 7 are composed of two substantially like frames 15 and. 16 provided with continuous. recesses 15'16' suited to receive plates Hand 18 bearing registry marks 19,20 and l9'20, at their respective side, and end edges, these plates being securely held in the frames by clamps 21, disposed preferably at Opposite corners and set at least flush with the faces of the frame.

Extending from the side of the frame 15, near its'ends, towards the frame 16; are a pair of lugs 23, and rigidly attached to the adjacent member of the frame 16 is a bar 24 reaching outwardly beyond the frame at each end both of which are slotted to receive sleeves 25 pivoted on the points of opposed screws 26 set in the bar ends.

Passing freely through the sleeves 25 are the plain cylindrical portions of adjusting screws 27 having flanged operative heads 27 and fixed collars 28 at the opposite ends of the sleeves, while the threaded portions of the screws engage in blocks 29. v

Also passing through the blocks 29 are the unthreaded end portions of a screw 30 screwthre'adedly engaging the lugs 23, the screw having an operating knob 30 by which it may be rotated.

From the foregoing it will be manifest that the frames 15--16 may be positively moved to a limited amount towards and from each other,

whether in parallelism or at moderate angles, and furthermore the frames may be shifted relatively frame 35, the same being engageable by studs 31 set in the ends of the frame 16, which after having been tightened, permit shifting of the frame 15, by the means herein described, to cause registration of the marks 20 with the line 3'7 and the marks 19 with the lines 36.

After the marks and lines have been brought in perfect registration, the frame 35 is removed, the frames 15-16 are placed upon a transfer plate having openings 4141 conforming generally to the frame openings.

Disposed intermediate the registered frames 15-16 and surface of the plate 40 is yielding element 42, such as a rubber blanket having slots 43. through which may bepassed clamping means, as the hooks 44 pivoted in recesses in the plate 40 on pins 45, these hooks being engageable with the frame projections 31-31', as seen in Figs. 3, 4' and 8 and in detail in Fig. 6.

The plate 40, which may be considered as a transfer element, is provided with perforations 46 in its end portions, adjacent to which are slots 47 to adjustably receive bolts 48 by which adjustable arms 49 may be securely clamped in position.

Perforations 50 in the arms are engageable with dowels 51 set in a plate 52 and also with exactly similar dowels set in the face of the machine to which the previously described devices ;are transferable.

' The plate 52 is provided with cross marks 5354 and operative devices, as indicated by the arms 55 engageable in the openings 46 to bring the elements into exact registration thence to be clamped by the bolts 48.

A series of studs 56, adjustable on the plate 52, provide means for levelling and supporting the plate 40 during adjustment and a marginal seal 57' encloses the space between the plates .-2 40-42, the space being served by a suction tube 58 whereby a partial vacuum may be produced between the plates 40-42.

In Figures 7 and 8 the construction is essentially the same as depicted in Figs. 1 and 3 with respect to the frames and their relative adjusting devices, but in the modification the frames are disposed on an apertured plate 60 and each frame is provided with a border seal 61-61 the spaces between being served by suction tubes 6262 to produce a vacuum.

Figs. 9 and 10 disclose one of the negative plates 65 clamped in a fixed position and theother plate 65 provided with set screws 6? adjustable in lugs 68 upstanding from an apertured plate 69 by which the plate may obviously be moved into as many different positions as the plate 17 with which it agrees in registration marks.

Figure 10 shows the plate 69 as having a marginal seal '70 interposed between it and an aper-. tured plate '71, the enclosed space having leading into it a suction tube 72 by which a vacuum may. be produced. v 1

The preferred form of space sealing means is well indicated in Fig. 11, but is not to be understood in a limiting sense. i

A partial section of a plate support frame 75 is formed with an inreaching lip, in which may be set a thin light sealing element 76 upon which the marginal edges of the plate 78 are seated.

The edges of the plate are bevelled and held firmly on the frame by a plurality of non-metallic clips 80, such for instance as indurated fiber, hard rubber, or any of the phenol resins, tough, firm and slightly elastic when drawn into engagement by the clamp screws '79.

These clips are slightly thinner than the plate 78 and outwardly, beyond their opposite edge is a circurnambient space 81 surrounded by a sealing member 82 on which another plate may be seated and drawn into desired intimate relation with the plate 75 by producing a vacuum in the space 81.

'Although the foregoing is descriptive of the preferred embodiment of the sealing means, inclusive of the clips and sealing member, it is to be understood that the invention is not confined to the exact structure shown and described, as equivalent devices of widely variant nature may be substituted therefor.

The foregoing disclosure-is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed ineluding many modifications without departing from the general scope herein indicated and denoted in the appended claims.
