10 Claims.

My invention relates to layout or key sheet registering devices and particularly to registering devices for registering make up sheets for printing work.

In preparing forms for printing, it has been customary to register certain plates with respect to a transparent layout or key sheet, which is then printed, then to register other printing plates, Where multicolor printing is done, by positioning the transparent layout sheet as accurately as has been possible and by the use of rulers and other instruments, and then positioning the plates for the successive printings with respect to the printed areas on the layout sheet.

If in thepositioning of the make up sheet there is any inaccuracy the plates for the successive printings will not be in exact registry.

It is the object of my invention to provide means by which the position of printing plates may be predetermined by the accurate positioning of layout sheets.

It is a further object of my invention to provide a registering device which will greatly facilitate, and thus reduce labor and expense, in positioning printing plates on either a cylindrical or flat bed foundation.

It should he understood that typographic printing from plates is carried out either with cylinders which carry the printing plates or with flat bed foundations. The supports for the plates are ordinarily plate registering devices having jaws which engage the side edges of the printing plates. The cylinders or flat bed foundation are provided with either grooves or a series of spaced holes within which the registering devices or hooks, as they are often called, may be held. The registering devices are ordinarily clamped in position by means of a key which is inserted down through the body of the device and by which the position of the device is determined both as to its orientation and alignment.

It is an object of my invention to utilize the grooves or holes in the bases or cylinders to accurately register layout or, key sheets, so that after an initial positioning has been made the sheet may be removed, the regular printing proceeded with, and then so that the sheet may be re-positioned on the base or cylinder in exactly the same position as it originally occupied when the original setting of the plates for the first run was made.

The foregoing object and other objects to which reference will be made in the ensuing disclosure, 1 accomplish by that certain combination and arrangement of parts of which I have shown a preferred embodiment.

In the drawing:

Referring to the modification of the invention in Figs. 1 to 6 a body I internally threaded as indicated at 2, for receiving the screw 3 which has a squared opening 4, by means of which the screw may be rotated with a wing type key having a squared bit conforming to the shape of the square opening 4.

Mounted in the body I, on a pin 5, I have shown a bottom latch 6 and back latch 1.

Upon rotating the screw 3, as illustrated in Fig. 5, thetip of the back latch 7 is wedged against the side wall of the honeycomb opening within the foundation base generally indicated at 8.

It should be understood that the device illustrated in the drawings, Figs. 1 to 6 is for use with what is technically known in the trade as a honeycomb base. Such a base is provided with a series of cylindrical openings. The openings are of a lesser diameter toward the top surface of the foundation base than towards the bottom surface so that an annular shoulder 9 is ordinarily provided against which the tip of the back latch abuts in certain positions of adjustment.

Extending from the body I of the device, there is a boss provided with a threaded opening H. An annular cutter head I2 is countersunk within an opening l3 in the boss Ill, the inner Wall of the cutter head being sufilciently thin so as not to interfere with the insertion of a threaded screw into the threads I I.

In Figs. and 6 there is shown layout or key sheet I 4 secured in position in a perforation l5 caused by contact with the cutter head l2. The layout or key sheet is positioned with respect to the foundation base and a thumb nut l6 having a threaded stud shaft I! is screwed into the threaded opening H in the boss It). An annular shoulder l8 presses the area surrounding the perforation in the layout or key sheet into contact with the cutter head.

It will be observed that the upper surface of the device illustrated in Fig. 1 is provided with indicia lines I9, 20. I

The foundation base 8 illustrated in plan view in Fig. 4, is provided with cross lines 2|, which make it possible to accurately position the device after it has once been removed, and is being reinserted in order to accurately determine the position of the layout or key sheet.

By means of the indicia lines l9 and 20 in the upper surface of the device the device itself can always be adjusted to substantially an exact position, in which position the perforated openings in the layout or key sheet can be registered with the cutter head, and the sheet held in fixed position by turning down the thumb nut In Fig. 4 there is shown a layout or key sheet I4 held in position by the two devices of which the thumb nuts l6 are shown in opposite corners.

Since the body I of the device is rotatable,

= and since the boss Ill extends out from the side wall of the body the axis of the threaded opening II is of course, eccentric to the axis of the threaded opening 2, so if it were not possible to accurately determine the direction in which the boss Ill extends, the operator could never be sure that the registering device was put back in the same position which it had originally occupied. It is for this reason that the indicia lines I9 and 20 which may be set with respect to the lines 2| in the foundation base, is of considerable importance.

In Figs. 7 to 12, the same type of cutter head 12a is used, and the make up sheet Ma is held in position by means of a knurled nut l 6a The diagonal block 8a illustrated in Fig. 9, instead of being provided with honeycomb holes, is provided with grooves, which grooves as indicated at 5a, are provided with shoulders within which the devices for positioning the layout or key sheet may be positioned.

Referring to Fig. '7, the device carrying the cutter heads |2a have bodies 22, having recessed portions 23 at the ends thereof within which are seated springs 24, which springs assist in the positioning of the device in the grooved plates.

The bodies 22 are provided with threaded openings 25, within which are seated screws 26, having squared openings 21, for receiving the squared bit of a'wing key. When the screws 26 areturned down, the springs 24 have upper portions 28 which interlock underneath the ledges 9a in the diagonal grooves of the foundation base. The upper surface of the devices illustrated in Figs. 7 to 12, have indicia lines 19a, which may be used in a similar manner to the indicia lines IS in the devices for use with the honeycomb base to accurately position the cutter heads within the grooves.

In Fig. 9 there is shown a layout or key sheet Ma positioned by means of the knurled heads N50 holding the sheet down against the foundation base. The knurled headed nuts I60 have an annular shoulder I 8a which bears against the upper surface of the sheet.

It will be obvious that the devices which I employ for holding the cutter heads in position are similar to what are known in the art as printers registering hooks. These are of two types, the drop in hook, such as is similar to the devices shown in Figs. 1 to 6, and the diagonal hook, such as is shown in the devices illustrated in Figs. '7 to 12.

The novelty of the devices which I propose to employ lies not in the manner in which the devices are positioned either within a honeycomb base, or a diagonally grooved base, but in the use of the cutter head and the knurled nuts IS with annular shoulders l8 by means of which the layout or key sheets may be accurately positioned during the arrangement of the printing plates on the foundation bases for one or multi-color printing. Since the device is used either with a foundation base or plate cylinder in the claims which follow, I have used the word base as indicating either type of support for the printing plates.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
