O'CONNOR, OF BROOKLYN, NEW YORK.
TYPOGRAPH'IC FO'RM.
Application filed March 23, 1923-.
To all whom it may concern:
Be it known that I, Gnovnn M. Rnrr, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Typographic Forms, of which the following is a specification. V
This invention relates to a device for nonadjustably positioning printing plates on a collective form base.
hen a number of printing plates, such as electrotypes, are imposed on a base in collective form, a careful adjustment of the face of each individual plate of each and several forms of a specified job to be printed is required to bring each plate into its proper position on the base relative to the face of the other plates. This requires the printing of several trial sheets from each form of adjustably imposed plates and the readjustment of' the plates of each and the several forms until they; are accurately positioned.
An object of the present invention is to provide device by which ordinary adjustable printing plates may be accurately and non-adjustably imposed in proper position on the first form or on the several following forms without the necessity of trial sheets or manual adjustment of plates either on the first form or on the following forms. I
Another object of the invention is 'to provide printing plates and a collective form base each having co-operating means for non-adjustably positioning said plates on said base and holding them from movement horizontally. I
Another obj ect of the invention is to p rovide non-adjustable positioning means in the base and the adjacent bottom} surface of the printing plate by which the plates are collectively directions.
Another object of the invention is to pro; v de as holding means grooves so situated 1n the bottom of the platejzas to be aligned with the printing face of the plate.
A further object of the invention is to provide co-operating means of grooves in the plates which so co operate with grooves in the collective form base as to obtain an accurate alignment of the printing face ir spaced and aligned in two Serial No. 627,064.
respective of the faulty or irregular flange edges of the plate. v
With these and other objects in view the invention comprises the'device described and set forth in the followingspecifications and claims. i v v Thevarious features of the invention are illustrated in the accompanying drawings in which: Fig. 1 is a plan View of a base and an assembled group ofprinting plates mountedf thereon illustrating an embodiment of my invention. 7
. Fig. 2 is a section on line 2-2 of Fig. 1. Fig. 3 is a perspective View ofthe collective forn base with one plate in place and the splines-shown'in position. Fig. 4: is a view of the' bottom surface ofa plate such as shown in Figs. land 3; Fig. 5 is a perspective view of the splines. Fig. 6 is a perspective View of another form of spline shaped 'asa cross suitable for use with any of'the bases. I w
Fig. 7fis a planview of a base and an assembled group of printing plates illustrating another embodimentpf myinvention.
Fig. 8 is a View in perspective of; the collective form base with one plate in position. Fig. 9 is a section on line 99 of Fig. 7. Fig. 10 isa view of the bottom surface of a plate such as shown in Figs. 7 and 9. Fig 11 is an assembly of splines suitable for use with the structure shown in Figs. 7 and 10. l
In the present invention the base onwhich the plates. are imposed is provided with positioning means extending in intersecting or 'co-ordi'nating directions and the printing plates are provided-with corresponding positioning means so positioned that when they are imposed on the non-adjustable p0- sitioning means ---in the base,"'o'r-in"th'eir cooperating relation to the means of the base,
the printing faces are in'their exact spaced and aligned position. The positioning meansin'the base is preferably formed'of a system of grooves part of which are 'parallel to each other and at right angles to other parallel'grooves. The printing plates are provided on their bottom surfaces'with (Jo-operating grooves, also arranged atrightv angles and adaptedto be positioned in the plates so that when superposed on the grooves of the base the plates are in their correctly spaced and aligned positions. Separate splines or keys are positioned in the grooves of the base and project into the grooves of the printing plates in such manner that when the plates are properly positioned to bring the grooves of the plates and base into superposed position the splines will engage and hold the plates in their proper and non-adjustably aligned position.
Referring more particularly to the accompanying drawing, a base is provided with grooves 12'extending in a longitudinal direction and grooves 14 intersecting the grooves 12 at right angles as shown in Figs. 1 to 3 or with cross shaped grooves as shown in Figs. 7 to 9. The parallel grooves 12 and 14 or the cross shaped groove 15 are non-adjustably spaced in accordance with the collective form to-be printed and the size and spacing of the plates to be mounted on the collective form base.
Similarly, the respective cross shaped groove 15 in the base and 29 in the plate are so positioned as to give the correct spacing and alignment.
In assembling the plates on the base, which base may be a single piece of material or made up of a plurality of pieces of material fitted together, it is only necessary to place the splines in the grooves of the base and place the plates in position so that their grooves engage the splines to accurately position the printing face of the plates on the base. be fastened to the base by means of tacks 34 driven into the flange edges 30 and 36 at the edge of the plates in the usual manner or may be fastened to the base in any other suitable manner.
Through this invention a rapid and accurate positioning and alignment of the printing'face of the plates on the base is assured and the shifting of the plates on the base and testing of the accuracy of their adjustment with trial sheets are avoided.
The base, illustrated as one solid piece, can obviously be made up and composed of and from a plurality of individual base blocks, with each individual block grooved so as to co-operate with the non-adjustable means for positioning a collective form of printing plates.
As changes of construction could be made within the scope of my invention, it is intended that all matter contained in the above description or shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is: I
1. A. device of the type described which comprises a form base having in collective formation grooves in its upper surface extendingrin intersecting directions to each other, splines in said grooves and plates having grooves in their bottom surface posi tioned non-adjustably to receive said splines.
