HORACE W. HACKER, OF CHICAGO, ILLINOIS.

METHOD OF AND APPARATUS FOR MARKING OBJECTS.

Application filed ma a,

in different colors, eifected from said plates upon the same print will be in exact register.

In carrying out the process of my invention in the preferred way, equally spaced indices or marks are provided upon all the plates of a set. These indices may be half toned upon the plates from marks provided 15 upon the original drawing or other copy.

I then place the indices upon each plate that is to be marked in visible registr with indices upon a gauge. A marking e ement is employed that is maintained in fixed relation with the gauge whereby marks may be successively placed upon the plates in exactly the same location with respect to the picture or print to be compositely produced from the plates.

In the preferred embodiment of the invention, I employ means whereby the marking element is not only maintained in fixed relation with the gauge but also a guide for the marking element, also in fixed relation with the gauge. The marks that are formed upon the plates by means of the apparatus of my invention are desirably holes and the marking element is a drill whose guide is in the form of a sleeve that is fixed in position with respect to the gauge. These holes receive positioning pins that are provided on the printing bed, the holes and pins cooperating to enable the imposition of the plates in succession in exactly the same place upon the bed.

- The invention will be more fully explained by reference to the accompanying drawings in which Fig. 1 is a plan view illustrating of the invention, this figure also showing one way of using the apparatus; Fig. 2 is a sectional view on line 2-2 of Fig. 1; Fig. 3'

another way of using the a paratus; Fi 9 illustrates the im osltion of a plate marked as illustrated in ig. 8; Figs. 10, 11, 12, 13 and 14: illustrate plates with diiferently arranged and differently formed indices thereon; and Fig. 15 diagrammatically illustrates a two color print which may be printed from two plates similarly marked in accordance with the invention.

Like parts are indicated by similar characters of reference throughout the different figures.

The apparatus illustrated includes a rectangular bed 1 which constitutes both a support and'a positioner for each of the printing plates, such as the plate 2, which is to be marked. A gauge is rigidly assembled with this bed. The-gauge is desirably in the form of a T-square, the head 3- of the T- square bein fixedly assembled with the bed by means screws 4 which pass through the ends of the T head into opposite sides of the bed. The stem 5 of the T-square is desirably assembled with the third side of the bed by means of screws 6. The head and stem of the T-square are desirably in the form of frames that respectively carry glass or other transparent panels 7 and 8 that are immovably held in their frames. A space intervenes between the T- square and the bed into which each printing plate, such as a plate 2, is slipped. This plate 2 is illustrated as having complemental indices 9 and 10 and other complemental indices 11 and 12.

The glass panels 7 and 8 in the an ularly related branches of the gauge are 'ormed with

straight lines

13 and 14 respectively, these lines being at right angles to each other and respectively parallel with the portions of the gauge on which they are provided.-

These lines constitute indices upon the gauge, each line being a loci ofpoints with which the-indices upon the plate may be.

brought into visible register. When the plate is initially marked as indicated at 9, 10, 11 and 12 in Fig. 1, it is adjusted to bring its mark 10 in visible registry with the line 14 and its line 9 in visible registry with the line 13 upon the gauge. When the plate'is thus positioned a drill 15, which the preferred form of marking element, is

pa ed h g t e p ate 0 rm a h e 16 therein. After the hole 16 is formed the plate is reversed to bring the index 12 in visible registry with the line 14 and the index- 11 in visible registry with the line .13 whereafter the drill is operated to form the hole 17.

In order that the drill may form the hole in exact relation to the registering indices upon the gauge and the p'.ate 1 provide the guide 18 which is in the form of a sleeve that passes through the bed and is therefore fixedly positioned with respect to the bed and gauge. The invention is not to be limited, however. to the employment of the drill guide inasmuch as the mechanism for operating the tool is likewise rigidly positioned with respect to the gauge and bed.

The drill operating mechanism illustrated includes a motor 19 in driving relation to the drill and carrying a depending rack 20 in mesh with'a pinion 21 that is journalcd upon a bracket 22 carried by the mounting 23 which is fixed upon the bed. A lever 24 is in turning relation to the pinion whereby the motor and the drill carried thereby may be elevated and lowered as desired.

The indices 10 and 12 are shown as being in the nature of crossed lines. The exact intersection of the crossings of these lines are each brought into registry with the line 14. If the plate be provided with but two indices 25 and 26 (Fig. 3), the use illustrated in Fig. 3 may be adopted. The intersection of the crossing lines that makes the index 25 is placed in registry with the line 13 upon the gauge and the intersection of the other crossing lines that makes the index 26 is placed in registry with the line 14' of the gauge whereafter the hole 27 is drilled.

The plate is then reversed in position to bring the index 26 in registry with the line 13 and the index 25 in registry with the line 14, whereafter the hole 28 is drilled. If the plate be provided with indices in the form of

long lines

29 and 30 crossed by dotted lines 31, 32, the method of forming the holes 33. 34 illustrated in Fig. 8 may be employed. The stem of the gauge in this figure has two

parallel lines

14, 14 in the plass panel thereof that are upon opposite sides of the axis ofthe drill and sufliciently removed therefrom so that the intersect-ion of the lines 29 and 31 may be brought into registry with the line 13 when the intersection of the lines 30 and 32 is in registry with the line 14 to permit the drill to form the hole. 33 in exactly the right place. When the plate is reversed to form the hole '34 the intersection of the lines 30, 32 may be brought into registry with the line 13 when the intersection of the lines 29'and 31 is in registry with the line 14' .to enable the formation of the hole 34 in exactly the right place.

Figs. 10 to 14, inclusive, illustrate various indices, some of which have already been mentioned, upon printing plates, these figures showing the plates before the holes are produced therein. Figs. 10 and 14 illustrate two complemental plates with similar indices and Fig. 15 illustrates the print that may result from these plates after they have been properly drilled or otherwise marked and suitably imposed. The plates shown in Figs. 10 and 14 hear such indices as are illustrated in Fig. 1 on the plate 2. Fig. 11 illustrates the indices upon the plate of Fig. 3. Fig. 12 illustrates the plate shown in Fig. 5. Fig. 13 shows a plate with indices that are in the form of dots. In order to form one of the holes in this plate the dots 35 and 36 are placed in registry with theiliue 13 when the dot. 37 is placed in registry with the line 14. 'hen the other hole is to be formed the plate of Fig. 13 is reversed to bring the (lots 33 and 39 in registry with the line 13 and the dot 40 in registry with the line 14.

Any suitable means may be employed for imposing the plates upon the printing beds. I have illustrated a pin 41 in fixed relation to the bed a and a pin 42 upon a carrier 43 that is slidable in a slot 44 formed in the bed. The plate that is being imposed is positioned to enable one of its holes to receive the pin 41 whereafter the pin 42 is adjusted to enter the other hole.

The apparatus of my invention is an instrument of precision in the highly developed art of printing. By the use of this apparatus much time is saved in the imposition of color plates upon printing beds, as will be at once apparent to those skilled in the art.

\Vhen it is stated in the claims that a fixed relation exists between certain elements of the implement it is intended to mean that such fixed relation is only necessarily constant during the marking of one set of plates essential to the production of a 1 single design; and such definition of structure is intended to include within its scope implements of this character wherein elements are relatively adjustable so that one fixed relation may be provided therebetween l to mark one set of plates and another fixed relation provided. if 'necessary, to mark another set of plates.
