TRANSPARENT MAKE-UP PLATE FOR USE IN PRODUCING PAGE STEREOTYPE.

Application filed June 30, 1926, Serial No. 119,762. Renewed February 9, 1928 I am the inventor of those novel processes for printing stereotypes disclosed and claimed in my two applications for U. S. Letters Patent thereon, filed June 10th, 1926, under Serial Numbers 115,129 and 115,130.

I am also the inventor of that novel process for producing page printing stereotypes disclosed in that certain application for U. S. Letters Patent thereon, executed by me of even date herewith, filed contemporaneously with my present application and numbered 119,7 61.

In the second and third steps of the processes disclosed in my last above referred to application, I employ what is there called a transparent make-up plate, to which all the master sheets desired for a single page of printed matter are secured and thereafter handled, in the production of the page stereotype.

I am the inventor of said transparent make-up page plate and the same is the subject of this present application.

Two forms of such a transparent make-up page plate are illustrated in the accompanying drawings.

In said drawings like notations refer to like parts throughout the several views.

Fig. 1 is a plan view of an integral transparent make-up plate, of the kind which would be generally employed, shown on a scale of about one third size;

Fi 2 is a vertical section through a portion of said integral plate on the line 2-2 of Fig. 1, on a much larger scale than in Fig. 1, being full size;

Fig. 3 is a horizontal section through a portion of said integral plate shown in Fig. 1 on the line 33 thereof shown full size;

Fig. 4 is a plan view of a sectional transarent make-up plate, with the sections iield properly joined together in a printers chase, on a scale of about one third full size;

Fig. 5 is a vertical section through portions of the parts shown in Fig. 4 on other parts being broken away, size; an

Fig. 6 is a horizontal section through some of the parts shown in Fig. 4 on the line 6-6, other parts being broken away.

Referring now, in detaii, to the parts shown shown in full the line 5 5.

in Figs. 1, 2 and 3, the numeral 7 denotes the integral transparent make-up plate, which is preferably composed of a good quality of glass. This plate 7 is of sufficient size to hold all the master sheets of composition required or desired for a page of a newspaper or other publication. This plate 7 is provided on its face with a series of properly spaced column demarking grooves 8 countersunk therein parallel with each other and extending from near the top to the bottom of the plate, as clearly shown in Figs. 1 and 3, and is also provided with a series of paragraph demarking grooves 9, countersunk therein disposed parallel with each other and running crosswise of the plate at right angles to the column demarking grooves 8. Of the column demarking grooves 8, there will be as many, on the face of the plate, as there will be columns in the page of the newspaper or other publication intended to be printed. Of the paragraph demarking grooves 9, there will be enough, on the face of the plate. to provide for the demarking or distinguishing of all the paragraphs of composition intended to appear on the printed sheet. In other words, the face of the said plate 7 will contain many more of the paragraph demarking grooves 9 than would likely be used for any single page of composition. The purpose of this excess number of said grooves 9 is to afford selective locations to fit the paragraphs of the composition of the master sheet for any given page of printed matter.

In the modification illustrated in Figs. 4, 5 and 6 of the drawings, a series of glass sections 10 are employed to constitute the transparent make-up page plate of the proper size, with these sections 10 properly abutted and held together in a suitable chase 11. The chase 11 is of larger size than the make-up plate composed of the glass sections 10, and the clamping action is secured by set screws 12 seated in the chase frame and hearing at their inner ends against pieces of printers furniture 13 working as abutments against the corresponding adjacent edges of the sectional make-up plate, as clearly shown in Fig. 4 of the drawings. These pieces of furniture 13 are preferably composed of wood, so that they will yield slightly under the action of the set screws 12, thereby securing reliable clamping of the sectional make-up plate to the chase frame.

This sectional make-up plate shown in Figs. 4, 5 and 6 is provided on its face with column demarking grooves 8 and paragraph demarking grooves 9 similar to the corresponding grooves of the integral plate shown in Figs. 1, 2 and 3.

Respecting the chase frame 11, it should perhaps be noted that its side and end mem bers are rabbeted on their inner opposing faces to afford inwardly projecting flanges 11, best shown in Fig. 6, upon which the frame adjacent members of the glass sections 10 of the make-up plate may rest, when properly positioned within the chase. It should also be noted that the vertical depth of the rabbeted channels alfording the flanges 11 is less than the thickness of the glass sections 10, so that when the glass sections 10 are properly positioned in the chase, the face of the makeup plate will be a little higher than the frame members of the chase, as clearly shown in Fig. 6 of the drawings.

The word composition as herein used, and as used in my other applications above referred to, is employed in a broad sense to cover and include not only reading matter, but impressions made from cuts, or from half tones, or from electroplates, for use in association with the reading matter or independently of the reading matter.

he expression master sheet or master sheets as herein used, is employed in the same sense as in my other cases hercinbefore referred to. In one form thereof the body of the master sheet is translucent and the composition thereon is in opaque impressions. In another form thereof the body of the master sheet is opaque and the composition therein is in translucent impressions. The first named form can be prepared on a typewriting machine, by using a good quality of white paper, with a carbon faced to the back of the paper, thereby getting impressions both on the face and on the back of the white sheet, and these will be sufficiently opaque to prevent rays of light from passing therethrough. The other form of master sheet can also be prepared on a typewriter by using a wax faced thin sheet of fabric of the kind ordinarily used for mimeographing. The Hammond machine is best adapted for this purpose, as the impressions are secured on that machine by blows against the sheet when held stationary against the face of the type. lVhen so treated, the wax on the face of the sheet will be displaced at the surfaces thereof struck by the tyneor more accurately speaking-bearing against the face of the sheet at the time the blow occurs, thus rendermg the impressions on said opaque sheet translucent. The master sheets for what is ordinarly called out matter to wit: matter printed from cuts, half tones, or electroplates is obtained from such cuts, half tones or electroplates in the ordinary way and then used in association with the reading matter master sheets.

lVith the foregoing explanation in mind, the usage and advantage of my transparent make-up page plate herein disclosed can readily be understood.

Assuming that all the master sheets of composition, whether for reading matter alone, cut matter alone, or the two kinds of composition in association with each other, have been prepared for a single age of print, they will be assembled in the order desired on the face of the transparent make-up plate, and will be pasted fast thereto, and thereafter be handled therewith. The presence of the column demarking grooves and the paragraph demarking grooves on the face of said make-up plate, facilitates the assembling of said master sheets and the accuracy of their location thereon. If it is desired that the columns and the paragraphs on the printed page shall only be distinguished by white spaces, then no inking of the said grooves of the make-up plate is necessary; but of it is desired to distinguish or demark the columns of print by black lines or the paragraphs of the columns from each other by black lines, then the said column and para graph grooves of the face plate are filled with ink by a ruling pen before the master sheets are assembled on and pasted fast to the face of said plate. The filling of said grooves with ink makes the faces of the filled grooves opaque, so that the rays of light cannot pass therethrough.

After the master sheets have been secured to the said transparent make-up plate, they are handled collectively with said plate in securing a transfer of the composition to the face of a metallic stereotyping plate, in the same way as described for unmounted master sheets in my pending applications, S. N. 115,129 and s. N. 115,130. In other words, a suitable zinc or copper stereotyping plate is provided havin its face sensitized with a material which is normally soluble in water but can be made insoluble in water by exposure to light. The said make-up sheet containing said assembled master sheets is then applied face downward to the sensitized face of said stereotyping plate and subjected to a strong light, such as an electric are light. The result will be that the sensitized material on the surfaces of said stereotyping plate not covered by the opaque composition impressions of the master sheet will be rendered insoluble in water by the actions of the rays of light thereon. The rays of light, however, cannot pass through the portions of the master s eets occupied by the opaque c0mposition impressions or through the grooves of said make-up plate occupied by ink, and

- grooves in the face of the make-up hence, the sensitized material on the surfaces of the stereotyping plate covered by said 0 aque composition impressions of the master s eets covered by the opaque ink filling of the plate will remain insoluble in water. Then the stereotyping plate is washed with water, to

. remove the sensitizing material from the surfaces thereof which had been covered by the o aque impressions of the master sheets and t e ink filled grooves of the make-up plate,

thereby leaving all the printing sur es exposed. Then said exposed surfaces of said stereotyping late are covered with a material which Wlll resist the chemicals used in the next two steps. Ordinary printers ink will serve this purpose, and can be readily applied with suitable inking roller. Then the sensitized material is removed from the surfaces of said plate which have not been covered by the opaque im ressions of the master sheet, and the ink filled grooves of the make-u plate, which can readily be done by swab ing the stereotyping plate with a dilute solution of hydrochloric acid. Then the next or final step consists in etching off from the face of said metallic stereotyping plate all the face surfaces thereof not corresponding to the composition of the master sheets and the column and paragraphing demarkin lines of the make-up sheet.

The a1 result is a page stereotype in flat form, which could be used on some forms of printing presses. For newspaper work, how ever, the at age stereotype would be curved, to half cylin er form, by the suitable application of pressure thereto, and these curved stereotypes of half cylinder form would be mated 1n-the proper sequence, and ap lied to the cylinders of the printin press in t e same way as curved stereotypes rom matrix molds are now applied.

In the foregoing description of the making of the page stereotype, it has been assumed that the preferred form of m process dis- CluSGCl in my foundation app ication S. N. 115,129 will be employed. If the modified form therein disclosed and broadly claimed and also disclosed and specifically claimed in my a plication S. N. 115,130 is used, correspon ing changes in the description of the steps to be followed for producing a page stereotype would have to be made. In the foregoing description, my transparent makeup pa e plate no attention has been called to the title of the page. If that title happens to be a permanent one, like in the case of newspapers no special aper master sheet thereof is needed, but, on t e contrary, said title ma be painted directl on the glass plate in blac paint or ink and t en will act in the same way as the master sheets of composition.

The integral form of the transparent make-up plate would generally be employed for master sheets containing the ordinary reading matter composition. The sectional form of the transparent make-up plate could, and robably would, be employed or the master s eets containin display advertisements; for the reason t at it would enable proofs of individual ads to be furnished to the different advertisers from the master sheets of such advertisements (by blue printing the same from the master sheets) in advance of the general assembly thereof on the make-up pa e plate, and then, if the advertisers shoul make corrections or changes, after seeing said proofs, it would only be necessary to correct the master sheets of the particular advertisements corrected. It is also an advantage for shifting or varying the relative positions of the different advertisements of different advertisers. Each glass section of the said make-up plate may be devoted to a particular advertiser; and then, the glass sections could be shifted relative to each other as desired, in the make-up or assembly thereof in the chase, so as thereby to give any desired relative positions to the different advertisements of the different advertisers.

Said glass sections 10 of the sectional make-up plate are, when assembled, joined together on lines which coincide with the column demarking lines 8 and the aragraph demarking lines 9 thereof. In 0t er words, the vertical joints of said lass sections will coincide with the column demarking lines 8 and horizontal joints of said sections will coincide with paragraph demarking lines 9. On Fig. 4 of the drawings these jointure lines of the sections are shown heavier than the other column demarking or paragraph demarking lines, in order to make the boundar lines of the glass sections 10, when assemble more distinct to the eye. For the same reason said glass sections 10, as shown on said drawing, are so shaded as to help distinguish the several sections from each other, to the eye. In practice, however, it will be understood, that the jointure lines of said glass sections 10, when assembled, in the chase, would be of the same size as the column demarking or paragra h demarking lines with which the coincid e.

t should, perhaps also be noted that, in practice there would be a large number of said glass sections 10 of different sizes, available from which selections could be made for the particular make-up of any desired page, whether the age is to be wholly of ads or partially of ass and partially of reading matter composition.

It may also be further noted that the particular mar 'nal glass sections 10 which are to be place with their outer edges directly abutting the corresponding chase frame members, on the sides of the chase opposite to the clamping members of the chase, will be a little larger in one or two dimensions, in

order to afiord marginal portions adapted to overlie and rest upon the inwardly pro ecting marginal flanges 11 of said chase frame members against which said glass sections abut, as clearl shown in F1 4 and 6. These marginal portions of said particular glass sections 10 will not be occupied by any of the master sheets of composition, for the obvious reason that the rays of light must come from the back when the make-up plate is applied to the metallic stereoptyping plate, for getting the transfer of the composition, and of course said rays of light can only pass through the exposed part of the glass.

What is claimed is:

1. A transparent make-up page plate, having parallel column demarking grooves and parallel paragraph drmarking grooves at right angles to said column demarking grooves, for assembling thereon and handiing together all the master sheets of composition required for a printed page, in producin a a e stereot of said composition, su staiitia lly as desbz i bed.

2. A transparent make-up page plate, composed of sections of glass abutting each other adapted to support on their faces taken collectively, all the master sheets oi composition required for a printed page, for handling the same together in producing a page stereotype of said corn osition.

3. The combination wit a chase and clamping devices of a transparent make-up page plate composed of sections of glass adapted to be held abutted edgewise together in said chase by said clamping devices, and which glass sections, taken collectively, are adapted to hold on their faces all the master sheets of composition r uired for a printed page, for handling sai master sheets together in producing a page stereotype of said composition.

In testimony whereof I ailix my signature.

ROY V. GRAVES.
