LETTER FOR LlNOTYPE-BARS.

SPECIFICATION forming part of Letters Patent No. 565,252, dated August 4, 1896.

Application filed February 7, 1896. Serial No. 537,628. (No model.)

To all whom it may concern:

Be it known that I, ANDREW B. ADAIR, a citizen of the United States, residing at the city of Evanston, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Letters for Linotype- Bars, of which the following is a specification.

My invention relates to improvements in type-bars, usually called linotypes; and the object of my invention is to produce a type-bar having a letter which will extend over the space occupied by two or more of such type-bars as are produced upon linotypemachines. Heretofore letters extending over more than one line of type produced upon such machines have been made by casting upon one of the type-bars letters which extend beyond such bar, but which when placed in position for printing must be supported by the type-bar next adjacent to it. The disadvantage of this construction is that it frequently happens in practice that the lower or projecting portion of such letter is not firmly supported by the adjacent type-bar when the type-bars are assembled, and owing to the great pressure which is necessary in printing from type-bars, or producing a matrix from such type-bars, such projecting portion of the letter is liable to be broken or bent so that a proper impression cannot be obtained from it. My invention obviates this difficulty without any necessary change in the mechanism of the machine upon which'such typebars are produced.

My invention can be accomplished on any of the machines now used for producing typebars; but as an illustration of a machine for producing such type-bars I refer particularly to the machine invented by Ottmar Mergen thaler, as shown and described in Letters Patent of the United States No. 378,798, dated February 28, 1888, for a machine for producing type-bars.

The process by which my improved typebar is produced having such two-line letters, or letters covering more than two lines, consists in arranging the letter in separate parts, so that one part of the letter shall be supported upon one of the type-bars and the other part or parts of the letter shall be supported upon the type bar or bars next adjoining it.

This process may be accomplished in at least two different modes. Taking, for example, a letter intendedto cover two or more lines of printed matter, in one mode the whole of the letter is cast upon one of the type-bars, the lower part of the letter projecting below the face of one of the type-bars, but in the plane of such face and without support. One of the usual cutting or trimming knives -adjacent to the mold-disk then cuts ofi the projecting or unsupported portion of the letter. The whole letter is again cast upon the next type-bar, the upper part of the letter projecting above the face of the type-bar in the plane of said face and without support beneath it. The part thus projecting is in like manner out off by one of the usual knives, so that when the two parts of the letter remaining upon the face of the type-bars are brought together they will form a single letter covering at least two lines. Of course the letter must be cast upon the'proper portion of each of the typebars, and in such relation thatwhen the two bars are assembled one letter covering two lines will be the result. The other mode of preparing a two-line letter is to cast one part of the letter upon one of the type-bars and the remaining portion of the letter in its appropriate place upon the next adjacent typebar. This is accomplished by the use of matrices having the proper parts of the letter stamped or cut therein, the two type-bars being then properly assembled to form a single two-line letter.

The same processes may be applied to the production of a letter covering more than two lines.

Referring to the drawings which accompany and form a part of this specification, Figure 1 is a perspective view of two type-bars havin g letters formed thereon in accordance with the process first described. Fig. 2 shows the type-bars assembled with portions of the let ter on each bar. Fig. 3 shows type-bars having the letters formed in accordance with the second process set forth.

A denotes the type-bars, and H the letter which is intended to cover two lines. In the type-=bar shown in Fig. 1,which is formed in accordance with my first process, the letter H is formed as an entirety on the type-bar,

joining type-bar has the same letter cast on its face, as shown, but the other half of the letter is cast on the second type-bar, while. that portion of the letter II which in the firstdescribed bar is attached to the face of the type-bar projects beyond the edge in the, It will be apparent that when present case. the projecting portions of the two letters II are cut away and the type-bars assembled the remaining portions of the two letters will form a complete two-line letter.

In'the second process which I have set forth I form, in casting, but one half the letter H i on each bar, thus doing away with the necessity of cuttingawa-ythe projecting portions of the letters, the parts assuming the same positions when the bars are assembled as in thecase first described and-as shown in Fig. 2.

A type-bar having portions of a three-line letter formed thereon mayalso be formed by 1 following either of the processes set forth above, and the structure-of such three-line letter is so obvious that it is not deemed nec- 1 essary to illustrate or describe this in detail.

two-line letters of suclrconstruction that the letter shall be properlysupported so as to make an even impression. So far as I am aware I am the first to make a linotype-bar having a portion of a letter or character formed thereon and intended to register with other portions of the same letter formed on adjacent bars.

What I claim as new, and desire to secure by 'Letters Patent, is-

1. A 1inotype-bar having a portion of a letter orcharacter formed thereon, said bar being intended to cooperate with the adjacent bar to produce a letter or character covering a plurality of type-bar spaces.

2. A linotype-bar havinga portion of a letter or character formed thereon, said bar being adapted to cooperate with an adjacent bar, bearingthecomplemental portion of said letter, to fornia letter covering a pluralityof type-barspaces.

3. As an improved article of manufacture, a linotypesbarprovided with complete letters orcharacters on its printing-face,-and having a fragmentor ,portionof a j-letter or character in printing :alinement with said complete characters, said letter-fragment being intended to cooperate with .complemental parts or adjacent bars to produce a letter covering two or more type-bar spaces.
