Application filed May 4, 1914. Serial No. 836,339.

To all whom it may concern Be it known that I, ARTHUR K. TAYLOR, a citizen of the United States, and resident of Roland Park, Baltimore county, State of Maryland, have invented certain new and useful Improvements in Methods of and Apparatus for Obtaining Registering orms, of which the following is a speci fication.

The present invention relates to an improved method and apparatus for use in positioning cuts, dies, transfer impressions or type in printing, dieing and creasing or lithographic forms so that very accurate registration of impressions from a plurality of forms will be insured.

In the preparation of such forms for use, for example, in multicolor work according to the method at present in common use, an undesirable length of tim and amount of labor is required. If the manipulations and adjustments required to properly position the printing surfaces of the form or forms to be used for other than the primary impression, so that the necessary register of succeeding printings may be obtained, are carried out in the press room, the press must be. idle for considerable periods of time during each job. Frequently very fine or small misadjustment of a cut, die, or body of type will result in a considerable waste of material in addition to the loss in time and labor required to make the necessary correction.

By the method hereinafter described it is possible to prepare in the composing room, in a minimum amount of time, the several forms required for use in producing any particular piece of close register work,

in which a single sheet 15 necessarily sub jected to a plurality of operations; and obtain substantially correct and perfect register of the different impressions.

In the accompanying drawing: Figure 1 is an elevation of a form of apparatus adapted to carry out the invention as applied to printing; Fig. 2 is a plan of one of the printing forms shown in Fig. 1; Fig. 3 is a similar view of the other form illustrated in Fig. 1; Fig. 4 is a diagrammatic view illustrating the action of the embodiment of the invention shown in Fig. 1; and Fig. 5 is a similar view showing a slightly difierent arrangement of parts for carrying out the same method as the apparatus of Fig. 1.

The illustration of the several parts of the apparatus hereinafter referred to is more or less conventional in the drawings as the detail construction thereof can manifestly be varied within wide limits without departmg from the scope of the invention.

Referring particularly to Figs. 1 to 4, A designates the ordinary compositors imposing table or other suitable support adapted to receive the chase or form B, containing the type or printing surfaces from which the first or primary impression is to be obtained, and a form or chase C for use in producing a subsequent impression on a sheet previously printed from the form B.

On the table or support A is arranged an apparatus adapted to project an image or representation of more or less of the form B upon the form C so that type or printing surfaces in the latter may be readily positioned therein so that impressions therefrom will be caused to accurately register with the spaces provided therefor in impressions obtained from the form B. Said projection apparatus comprises two parallel, vertical, tubular members D, E connected at their upper ends by a tubular horizontal member F, mirrors or suitable reflecting surfaces (designated by G, H, in Fig. 4) being arranged within the member F at an angle of 45. A suitable source of light, for example an electric lamp, is arranged in a suitable housing adjacent the lower end of the upright D so that the portion of the chase or printing form B beneath said member D will be brightly illuminated; and within the upright D is arranged a light projecting system shown in Fig. 4 as comprising two double convex lenses I, J.

The apparatus is represented as resting upon suitable feet K (which are of such height and so arranged that the forms B, C may be adjusted as required to bring any desired portions thereof into alinement with the tubular uprights D, 0). As shown the lower end of the member E is situated in a horizontal plane somewhat above that including the lower end of the member D so .that the workman may obtain a clear view of the portion of form C beneath the tube E and that there will be suflicient space to permit of his eflecting any necessary ma nipulation or adjustment of printing surfaces'in the form.

In using the apparatus referred to, the

tube D will bepositioned above the form so that a space or blan'kin the printing surface of said form corresponding to a section of the finished Work which is to be printed from the form C, inva difierent color from the impressions obtained from the form EB, or a suficient portion of such a space, Wlll be in alinement withthe tube An accurate readily adjusted on said base as required and secured in proper position in the form G.

If more than two impressions are required it will be evident that other forms, each containing the printing surface, or surfaces, re-

.quired for any one color, will be successively positioned beneath the tubular'member'E of the projecting apparatus in place of the form C and the type, 'etc., therein adjusted as required in conformity to the primary printing form B,

the primary printing portion thereof, as

Instead of projecting a representation of form, or a .suficient a ove described, an im pression printed from such form may be substituted for the form B.

Comparing Figs. 2 and 3, it will be seen that it is not necessary that the entire area of the primary form B, orimpression therefrom, be projected onto the secondary form C, in order to accurately locate theposition in the latter of the printing surfaces 0, c, 0 so that impressions therefrom will correctly register with the spaces 6, 6, 6 It is only necessary that the projected image include a suflicient portion of the primary form and the space I), for example, to enable the type or electrotype, constituting the printing surface 0 to be placed in the proper, corresponding, location in the secondary form 0.

As the invention is primarily intended for use with large forms the projecting apparatus will be so supported that it can be readily shifted relative to the two forms, B, C, to bring different areas of the forms into alinement therewith as required. In carrying out the method hereinbefore described, the low or cut-out portions of the electrotype or printing member to be positioned in the secondary form may be dusted or powdered with a suitable white or light colored powder so that the high printing surface of such member will be clearly distinguishable, which will materially aid in adjusting said printing member into the proper position. Generally, the apparatus will be used in a subdued light or slightly darkened room.

It is not necessary that the primary form or impression to be projected be supported on the same table or level as the form for nieoeai efi'ecting a subsequent impression. A modification of the construction described, as regards this feature, is diagrammatically illustrated in Fig, 5, Referring to this figure, it will be seen that the form or an impression L therefrom is arranged on thelower face of a suitable support M positioned at a considerable distance above the imposing stone or table A. With such an arrange-- ment all of the projecting apparatusean be arranged within a single tube-like body N. As illustrated, the body N adjacent its upper end is provided with a lamp house or casing Oand interiorly of said bod is *arranged'a suitable'lens systemadapte to project animage or representation of the illuminated area onto the form mounted on the table A.

While in the foregoing description it is pointed outthat the invention is particularly adapted for'use in positioning electrotypes in registering position, it will be evident that it is not limited to that particular use. For instance, the invention may be employed with equal advantage impositioning lithographic transfers. Also instead of employing a form or impression therefrom, an outline drawing or lay-out may be projected ontothe secondary form to definitely define the boundary within which one or more electrotypes, for example, must be positioned. .As previously indicated, it is not necessary in every case to project an image of the entire space within which an impression from the adjustable printing surface of the secondary form is to occupy in the finished work, but merely a suflicient amount of detail thereof to enable the operator to properly locate the electrotype in the secondary form. It is customary to include in the primary form or impressions therefrom, or a drawing, certain positioning points and a projection of these, or a portion thereof, is all that is required.

The invention is also well adapted for positioning dies for cutting and scoring sheets so that registration of the outlines produced thereby will register with printed matter on said sheets, and the term impression form used in the claims is to be understood as covering any form which includes a movable or adjustable impression member, whether adapted to print, out, score or otherwise act upon a sheet or blank.

Having thus described the invention What I claim and desire to secure by Letters Patent is:

1. The herein described method of determining the correct position of a movable member in an impression form com prising displaying on the form an optical image of such necessary registering detail as to define the location for said member within the form.

2. The method of making up registering impression forms, each including a movable member, which comprises providing means containing suitable registering detail ofa plurality of members of a form projecting onto the surface where the mova le member is to be placed an image of a suflicient portion of said registering detail, and adjusting said movable member to bring corresponding parts thereof and of said image into superposed relation.

3. The method of making up registering impression forms, each including a movable member, which comprises supporting above a form a representation of suitable registering detail, projecting onto the form an image of a suflicient portion of said registering detail, and adjusting said movable member to bring corresponding parts thereof and of said image into superposed relation.

4. The method of making up registering impression forms, each including a movable member, which comprises providing means containing suitable registering detail of a plurality of members of a form, illuminating a suitable part of said registering detail, projecting onto the form an image of the illuminated area, and adjusting said movable member to bring corresponding parts thereof and of said image into superposed relation.

5. The method of making up registering impression forms, each including a movable member, which comprises placing the form on a suitable support, arranging above the form a representation of suitable registering detail, illuminating a suitable part of said registering detail, projecting onto the form an image of the said illuminated area,

and adjusting said movable member to' bring corresponding parts thereof and. of said image into superposed relation.

6. The combination with a support for an impression form, of means adapted to sustain above said support a representation of suitable registering detail to indicate the proper position of a movable impression member in a form on said support, and means adapted to project onto said support an image of a sufficient portion of said registering detail, for the purpose described.

7. The herein described improvement in the method of making up the secondary.

forms for use in multicolor printing comprising projecting an image of a sufficient portion of a primary form or an impression therefrom, onto a second form to define the location for a printing surface in the secondary form, and securing such a surface in 'alinement with said image.

8. An apparatus for use in preparing printing forms for multicolor printing comprising a hollow body adapted to have its ends positioned in alinement with suitable areas of a primary form, or impression therefrom, and a secondary form, means for illuminating the surface of the primary form, or impression therefrom, that is in alinement with one end of said body, and means Within the body for projecting an image of said illuminated surface onto the secondary form, for the, purpose described.

In testimony whereof I aflix my signature in presence of two witnesses.
