METHOD OF AND APPARATUS FOR PREPARING REGISTERING IMPRESSION-FORMS.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Application filed March 1, 1915. Serial No. 11,264.

paring registering impression forms and is particularly an improvement upon the method and apparatus described and claimed in an earlier application,

By the invention hereinafter described it is possible to rapidly arrange the movable members of an impression form, such as is employed in printing, embossing, dieing and creasing, lithographic or similar work, so as to insure accurate register of an impression therefrom with an impression or impressions from a similar form or forms.

According to the method described in the earlier application referred to, a representation. of an impression from the form to be made up, for example, is supported in a horizontal position above thework table and an image of a sufficient portion thereof is projected onto a form on said table as a guide by which the proper or correct position of the corresponding movable member of the form may be determined. It has been found that by the method hereinafter described the apparatus required to carry out the method of said earlier application may be considerably simplified.

In the accompanying drawings: Figure 1 is a perspective view of an apparatus embodying the present invention; Fig. 2 is a transverse, vertical sectional view of the apparatus; Fig.3 is a horizontal, section, view; Fig. 4 is a detail sectional view, on an'enlarged scale.

Referring to the drawings, it will be seen that the embodiment of the invention therein illustrated comprises a substantially rectangular frame 1 adapted to be supported on the usual work or imposing stone or table 2 and provided at its top with a glass plate 3. The frame 1 may be constructed in any suitable manner and the transparent top thereof held in place by any desired means.

A carriage-like frame 4 is mounted to move along side rails 5 secured to end posts of the frame 1, one or both of said rails being provided with a suitable rack 6 with which meshes a pinion 7 secured on a shaft 8 carried by the carriage 4. By actuating suitable hand wheels 9 secured on the ends of the shaft 8, the carriage 4L and all parts supported thereon may be adjusted longitudinally of the rails 5 The carriage 4 is provided with a centrally arranged housing or casing 10 that is supported to move thereon in a direction transverse to the length of the rails 5 and the line of movement of the carriage by the shaft 8. Said housing includes similar upwardly and downwardly directed section each of which terminates in a projection device or lens tube 11. Within the casing 10 is arranged a translucent plate 12, preferably of ground glass. Inspection of the images projected on the ground glass plate 12 by the lenses in the tubes 11 may be had through openings provided in opposite walls of the upwardly extending portion of the casing 10, said openings being preferably surrounded by outwardly projecting tubes 18 of such size as to receive an operators face.

As it frequently happens that the detailof the images appearing on the ground glass plate 12 is small, a magnifying glass 14 is preferably arranged within the casing 10, adjacent each of said openings, each of the glasses being supported so that it can be readily moved to and from a position across the adjacent sight or inspection opening of the casing. The handle 15 of each magnifying glass, as shown, extends to the outside of the housing so that the device may be readily manipulated by the operator, as desired. The housing excludes light from the ground glass plate 12, except such as passes through the lens tubes 11 and the inspection tubes 18. Either of the latter may be closed by a suitable cap and the other is practically completely closed when the apparatus is in use. Means are provided whereby objects Within the fields of the lens tubes may be illuminated, if desired. As shown, the housing or casing 10 has mounted thereon suitable electric lights and reflectors 16, 1.7 for this purpose.

In using the apparatus a drawing 21 or other representation of an impression from the form to be made up, or a sheet bearing suitable and sufiicient registering detail to indicate the proper relative positions in a form of the movable part or parts thereof, is placed upon the glass top plate 3. The carriage is then adjusted so that images of portions of said guide sheet and the form 20 are displayed on the ground glass 12, the sheet and form, or the areas thereof within range of the lens systems, being illuminated if desired or necessary. The operator 'then adjusts or shifts the movable member of the form the image of which, or of a sufficient portion of which, is displayed on the ground glass 12 until such image and the image thereon of the corresponding part of the sheet 21 are properly superimposed. The movable member of the form is then secured in position. The carriage and means thereon are so arranged that the lens tubes can be easily shifted so as to bring any desired portion of the areas of the form and guide sheet within the range of the lens systems.

It will be evident that there can be considerable variation in the details of the apparatus herein illustrated without departing from the spirit of the invention.

The term impression form is intended to include any holder, container, or base adapted to receive one or more movable members and retain the same in any adjusted position, so that impressions can, by aid of a suitable press, be obtained therefrom. In particular the invention is employed in preparing forms for multi-color printing, embossing and cutting or creasing blanks or sheets which have been or are to be printed and in which careful register of successive operations is necessary.

Having thus described the invention, what is claimed .and desired to be secured by Letters Patent is:

1. The herein described method of determmmg the correct position in an impresslon form of a movable member comprlsing superlmposing in register an image of a sufiicient portion of such member on an image of a corresponding part of a representation of an impression from the form.

2. The herein described method of determnnng the correct position in an impresslon form,of a movable member comprlsmg arranging a suitable surface in such relatlon to an impression form and a representation'of the impression to be produced by the form that images of portions of both sa d representation and form will be recelved thereon and manipulating said movable member until the image on said surface of suflicient registering detail thereof coinc1des with the image of corresponding parts of the representation of an impression to be obtained from the form.

7 The herein described method of deternnmng the correct p sion form of 'a' mova 1e member comprising arranging a translucent plate between the osition in an impres form and a representation of an impression to be produced by the form, projecting onto opposite faces of said plate images of portions of said form and representation, and manipulating said movable member until the image of sufficient registering detail thereof on the plate coincides with the image thereon of corresponding parts of the representation of the impression from the form.

4. The combination with a support foran impression form, of means for supporting a guide sheet or representation of an impression from such a form, and means adapted to superimpose images of corresponding parts of said sheet and a form on the support, to determine the correct pocorrect position of a movable impression member in such form.

6. The combination with a support for an impression form, of means for supporting a guide sheet, a casing or housing mounted to move relative to both said sheet and form supports, and two lens systems carried by said casing and adapted to display on a common surface images of portions of a guide sheet and a form on said supports, for the purpose described. 1

7. The combination with a support for an impression form, of means for supporting a guide sheet, a casing or housing mounted to move relative to both said sheet and form supports, a translucent plate within said housing, and two lens systems carried by the housing and adapted to respectively display on said translucent plate images of portions of a guide sheet and a form on said supports, for the purpose described.

8. The comblnation with a support for an impression form, of means for supporting a guide sheet in a horizontal position above said support, a casing or housing arranged in plane's between sald supports and movable longitudinally and transversely there- Q of, said housing being provided with an interior translucent plate and a lateral opening through which said plate is visible, and two lens systems carried by the housing and adapted to respectively display on the translucent plate therein images of ortions of a guide sheet and impression orm on said support, for the purpose described.

9. The combination with a support for an impression form, of means for supporting a guide sheet in a horizontal position above sa d support, a casing or housing arranged 1n planes between said supports and movable longitudinally and transversely thereof, said housing being provided with an interior translucent plate and a lateral opening through Which said plate is visible, two lens systems carried by the housing and adapted to respectively display on the translucent plate therein images of portions of a guide sheet and impression form on said supports, for the purpose described, and

means for illuminating the areas Within the 10 range of said lens systems.
