MAJOR A. BAN OROFT, OF BLUNT, DAKOTA TERRITORY, ASSIGNOR OF ONE- PRINTING.,

SPECIFICATION 'forming part-of Letters Patent/No. 351,618, dated October 26, 1886.

Application filed March 2G, 1886. Serial No. 106.687. (No mode'.)

To all whom t may concern,.-

Beitknown that I, MAJOR A. BANonoFT, a citizen of theUnited States, residing at Bl u nt,in the county of Hughesand Territory of Dakota, haveinvented certain new and useful Improvements in Printing, of which the following isa speciiication, reference Vbeing had therein to the accompanying drawings.

My invention relates to an improvement in to the art of printing, whereby a divided print may be obtained i'rom a solid printing-thee, as an electrotype or wood-cut, the intermediate space to'be afterward filled by an impression from another form, giving the finished print r 5 the appearance ot' an impression of' greater superficial area than the area of said printingface. -f

The nature of my invention will be clearly understood from the following description and 2o the accompanying drawings; Figure l ofthe drawings represents atympa bearing an impression of a form to be printed from, the dotted lines showing how the tympan is to be cut for the first impression andv the gage-pins in position. Fig. 2 shows the tympan prepared for the iirstimpression. Fig. 3 represents a frisket on which is an impression of the form, the portion to be removed being shown in dotted lines. Fig. 4shows the frisket 3o prepared for the i'irstimpression. Figs. 5 and 6 illustrate the preparation of the tympan for the second impression. Figs. 7 and 8 illustrate the preparation of the frisket for the second impression. Fig. 9 shows the product of the rst and second impressions. 'Fig. 10

shows the completed print, the blank space left between the first and second impressions having been filled by a subsequent impression from another form; and Figs. lland 12 rep- 4o resent impressions from the form, the latter 'ligure showing the'print separated on the line a: x, Fig. 1l, none ofthat part of the form used to make the first impression having been employed to make the second impression. Figs. 13 and 14 represent the tympan and frisket prepared for an impression from another form,

to ll the blank space between the divided iin-- pressions of the cut, as seen-in Fig. 10.

In the explanation of my invention it is assumed that the form to be printed from is a cut representing a two-story building,from which it is desired to obtain a print representing a three-,story building without in any manner mutilating the cut,and that the form is placed in proper position on any ordinaryjob-printv ing press.

' In carrying ont my invention I first take an impression of the form on the tympan A ofthe press, as shown at B, Fig. l. I then attach a sheet of heavy paper to the grippers C ot the 6o press to form a l'risket, D, on which, also, I take an impression of the form, as shown in Fig. 3', alter which I cut out that part of the irisket overlying the portion of the form fromv which I wish to take the first impression, as shown at E in Fig. 3, and then cnt out that portion of the tympan underlying that portion ofthei'risketcovering the remaining portion of the form, as shown at F in Fig. 2. Vhenpthese parts of the press are thus prepared, I place a 7o sheet oi'pap'erto be printed on the tympan, resting its edges against the gage-pins G, and take an impression.

It will be understood4 that only so much of the form as underlies the cut out part of the frisket will print on the paper, the frisket receiving the impression from the other part ofthe form. as shown at H, Fig. 4, and that, by reason of the tympan having been cut out,

as at F, Fig. 2, thispartIIof the t'risket will not 8o V he pressed so hard upon the paper being printed as to mar its surface, as would be the case if the paper were not allowed to yield.

For the second impression a new tympan` sheet isprovided. An impression of the form 8 5 is` taken upon it, as before, and the gage-pins G are lowered (or the form is raised) to such position as will give t-he desired space between the prints ,produced by the tirst and second impressions, this location of the pins be- 9o ing shown in full lines in Figs. 5 and 6. An impression is then taken on a new frisket, as seen in Fig. 7, and the portion necessary to be printed is cut out, as at E, Fig. 8.

1 It will be observed that in the illustration 95 here given the frisket is so cut as to includea portion of that part of the form which had been previously printed from, in order to give a symmetrical appearance to the iinished print. When the frisket is thus prepared,the tympan roo is cut out according to the directions above given, as shown atk F, Fig. 6. The sheets bearing the first impressions are then again run through the press, the product of the two impressions being a divided print, such as is shown in Fig. 9.

The third impression, to fill the blank space between the first and second impressions and complete the representation of a three-story building, may be had from another form, as shown in Fig. 10, which form is simply a single line of type with a piece of rule at each end and side in such position as to register with and complete the outlines of the impressions representing the building. For printing from this form the frisket is cut out, as shown at It] in Fig. 14, and thetympan is ent, as shown at F F in Fig. 13, leaving an uncut strip between the two cuts in the tympan, which strip is intended to underlie the cut part E ofthe frisket.

It is evident that the print may be divided on any given line, as x x, Fig, 11, and a divided pri nt-such as shownin Fig. 12-be produced without at the second impression in cluding any portion of that part of the t'orm printed from at the first impression.

By 'the method of printing above set forth divided prints can be obtained from letters as well as from ents.

I am aware of United States Patents No. 84,225. dated November 17, 1868, and No. 164,647, dated January 22, 1875, and make no claim to the inventions therein shown and described.

In another application, tiled by me o'n the lthday of December, 1885, Serial No. 185,940, the following claims are now pending and in process of adjudication, to wit:

1. The combination, with a form of type placed on the bed of a printing-press, of the frisket, the portions which overlie the part of the form from which it is desired to take an impression being cut out, and a tympan having the portions which underlie the part ofthe frisket covering the part of the form not to be printed from cut out,substanti ally as described.

1). As an improvementin the art of printing, the method herein described of taking an impression from certain portions of an unbroken form, consisting in cutting out those parts of the frisket which overlie those parts of the form from which an impression is t'obe taken, and removing those parts o1- the tyml'ian-shect which underlie the part of the frisket covering the part of the form not to be printed from, then applying paper to the frisk et and tympan so prepared and taking an impression, substantially as described.7

Having thus described my invention,what I claim, and desire to secure by Letters Patent, 1s-

1. The improvement in the art of printing hereinbefore set forth, consisting, first, in entting ont that portion of the frisket which overlies the part of the form from which the first impression is to be taken, and cutting ont so much of the tympan as underlies the part ot' the frisket covering the remainder ot' the form, and taking an impression on a sheet of paper; secondly, in arranging the frisket to cover so much of that part ot' the form first printed from as is not needed for the second impression, cutting out the tympan in the manner indicated above, gaging the paper in proper relation to the form, and taking the second impression; and, finally, in filling the space left between the two impressions with an iinpression from another f'orm.

2. An improvement in the art of' printing. consisting, first, in cutting out thatportion ot' the frisket which overlies the part of the form from which the first impression is to be taken, and cutting out so much ofthe tympan as underlics the part of the frisket covering the remainder of theiorm, and taking an impression on a sheet of paper; secondly, in arranging the frisket so as to eovera portion ot' that part of' the form first printed from, cutting-ont the tympan as indicated above, gagng the paper lower down on the tympan, and taking the second impression; and, finally, in filling the space left between the two impressions with an impression from another form.

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