DEVICE Fon PRINTING INTERSECTING LINES.

Application led August 23, 1920. Serial No. 405,406.

To auw/1,0m t may concern:

Be it known that I, JAMEs RosnNiii-io, a citizen of the United States, and ay resident of Cleveland, county of Cuyahoga, and State of Ohio, have inventedl a new and useful Improvement in Devices or'Printing Intersecting Lines, of which the following isa specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention relates to yan improved means-for printing lines for ruled pages or forms. on a cylindrical printing press, either in large numbers, or such-a printing press as a multigraph or the like. Thepresent improvements are particularly designed for use onmultigraphs which are of. great value in `printing forms of light impression.

The principal advantage of the present invention is that it provides a system 'of interlockingmembers which 'may be assembled anywhere, and then mounted lupon the cylindrical drum of a printing press or multigraph or may be assembled on a press and there locked into position. Any variety of spacing of the lines can be secured inthe present system, and obviously the system is not limited to use on acylindrical press, as it may also be used to advantage lin ordinary fiat form printing. To the accomplishment ofthe foregoing and related ends, the lsaid invention, then, consists of themeans hereiny"after fully described and particularly pointedo'ut intheclaims. n

The'annexed drawing` and the following `description set forth in detail certain mechanism embodying the invention, such disclose'd'means constituting, however, but one of various mechanical forms in which the principle of the invention maybe used.

In said annexed drawings l Fig. l is a plan :view of a series of my improved elements assembled together for printing a ruled form; Fig.l 2 is a; view in perspective 'of one of the spacing or inter- 'locking'elements; 3 is a similar view of v one ofy the printing'elements designedto be "received inthe element of Fig. 2; Fig. 4 is an- 'end' elevation of the spacing felement shown 1n Fig. 2; Figi 51s a similar view showing a modification of the element Fig.

6` is'fstill another view showing another modification; Fig. 7 is a transverse sectional view of an assembly of my various printing andspacing elements; Fig. 8 is a section on the line 8 8 Fig. 7; Fig. 9 is asection on the line9-9 Fig. 7; Fig. l0 is a transverse section through a spacing bar with a printing bar adjacent thereto; Fig. ll is a view in perspective showingthe method of assembly of the spacing element and the elements for printing intersecting lines; Fig. 12 is a plan view of an assembly of my improved elements mounted on the surface of a cylindrical drum; and Fig. 13 is a transverse section on the line 13-13 of Fig. l2.

The nature of my invention can best be understood from the inspection of Figs. l,

2, 3 and 1l. In Fig. l I have shown the various elements Aassembled and adapted to print a form in which there are transverselyr extending lines l andlongitudinally extending lines 2 intersecting the transverse lines.

For printing a form such as indicated in this figure, I use la series of interlocking and spacing bars t which maybe termed gauges, since they act to gauge the distances between. the other elements. Each of these bars 4L is provided with a series of equidistantly spaced and similarly shaped laterally 'be described. The teeth 5y on the gauges form between them recesses adapted to receive other elements presently to be described.

In-setting up the form shown in Fig. l there are usedffor example, :tour longitudinally `extending spaced gauge bars 4. In the Vcentral groeve 6 of each of these bars are inserted printing bars such as are shown in Fig. 3 carrying elements for printing lines which produce vertical lines on the page to be printed. For printing the transverse lines I employ a series. of thin printing bars 10 which are shown in Figs. 10k andll, and which may be snugly inserted between the spaced lugs or flanges 5 on the spacing'bars. The ends of these bars l are formed as indicated in Fig. l0, and are so constructed as to fit snugly against the printing elements 8 or lines on the element 7. and also against the body portion of the spacing bar 4. In this way the bars`r l0 may be brought to the same printing height as the bars 8, and intersecting lines may be printed in this manner as many bars l() being used as there are transverse lines desired in the finished page. In Fig. l0 I have shown the construction and character of engagement between the gauge bars 4 and the printing bars l0. The gauge bars are engaged between their teeth 5 in the recesses 60 by the printing bars, the latter locking over the extending portions 40 of the gauges. Also the projection 4l on the bar contacts against the lateral surface 42 of the printing element 7 while the lower surface of this projection rests on the shoulder 43 on this printing element. The recess 44 of the member l0 is constructed to enga-ge over the portion of the gauge with sufiicient clearance'to allow for convenient engagement thereover. A slight play in this engagement is not objectionable since it is only necessary that these members interlock, while the height is maintained by the positioning ofall members on the same base. That is, the elements 10 have the same height as do the elements 7 when mounted on the gauge 4.

In Fig. 7 I have shown a longitudinal section through an assembly of parts arranged for printing lines. In this view the gauges 4 are shown in spaced parallel relation carrying the line-printing elements 7. Vhile the bars l0 (not shown in this figure) will maintain the relation between the gauges, intermediate parts 50, known Aas spacing furniture, may also be used either with the bars 10 or in places where no bars are desired. These elements are formed to engage laterally with the gauges and are similar thereto except that they carry no printing elements, while they 'have lateral projections 5l engaging in the notched out corners 9 of the gauges.

After the printing elements have been assembled in the manner indicated in Fig. l they may be mounted about a cylindrical drum l5 by a cylindrical printing press as shown in Fig. 13, the printing press being.l of course, either the usual cylinder press or a multigraph. When so mounted they are locked in position by means of transversely extending end locking elements 16 which are of L shape andprovided with holes 17 adapted to receive bolts 1S adapted to lock into longitudinally extending grooves 19 formedy into drum 15. The upwardly extending portion of the L shaped members 16 are provided with downwardly extendingflanges 2O which engage between the spaced teeth 5 on the spacing gauges and lock the same in position against the surface of the cylindrical drum.

The present invention provides a means for printing intersecting lines on cylindrical presses while permitting the setting up of the printing elements anywhere as on a Hat form or page after which they may be locked in position on the cylinder. It is of particular value in connection with a multigraph as it very greatly enlarges the field of usefulness of such a machine, and enables it to print numerous varieties of office forms which are today so largely in use.

Othermodes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the fol lowing claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention l.
