Linotype Keyboard Practice (1947)

Linotype Keyboard Practice. (Brooklyn, NY: Mergenthaler Linotype Company, 1947.) This is an extract from Linotype Keyboard Operation (1940) . Printing code: 610.32-I-Z-10X.

The other booklets in the "Linotype Life Extension" series are all devoted to maintenance. This booklet, on keyboard use, seems out of place. It really should have been classified with other items of Linotype operation literature. The reason it is here (as it explains on its p. 3) is while the others reprinted material from Linotype Machine Principles , it reprints material from Linotype Keyboard Operation.

Instructions to Linotype Operators and Machinists

The booklet "Instructions to Linotype Operators and Machinists" describes itself as "a compilation of the various and sundry Instruction Cards formerly attached to the particular parts of the Linotype to which they applied." (Although they do not appear to have been literal reprints. At least one of them, for example, refers to a card on "the opposite page," which indicates that they were both re-set and rewritten for this booklet.)

Almost every edition of this booklet contains a slightly different set of Instruction Cards. But the editions all have the same title, and some have identical covers. There is no identification of revision/edition numbering encoded in the printing code. The only way to distinguish one edition from another is by the encoding of the date code in the printing code. So far, I've identified seven different editions. (If you know of others, I'd very much like to learn of them.)

Much of the material is duplicated from one edition to another. The simple option is just to reprint each of them in full. I'm not doing that here, but I'm not sure that the alternative path I'm taking is a good one. The problem with reprinting them all in full is that it given a particular need it is difficult to find the booklet with the appropriate version of the appropriate Card.

Instead, I'll do three things here.

First, I'll reprint a composite version which collects the front matter from one arbitrary edition together with each distinct version of each Card taken from the various editions.

Then I'll reprint each of these versions as a separate PDF. (I'll put the General Instructions first and the Memoranda last, but between them the order will be alphabetical, not as found in the booklets.) This should give the quickest access to individual Cards.

Finally, I'll reprint just the front covers and title page from each edition that I have, together with a listing of the individual Instruction Cards that it contained. From this you can assemble the edition of your choice, if you wish.

The dates here were determined from the printing codes using Jim Gard's cracking of that code.

Composite Version

A composite version which takes the front matter from the 1990-10-58-3M edition and includes one copy of each distinct version of each card, taken from this and other editions.

Note that this is a 270 Megabyte PDF. If you just need a particular card, use the individual PDFs, below.

Quick-Opening Advertising Figure Knife Block ["preceding page" version]

1 page. Extracted from edition 1990-E-MM-1X (May 1948).

This version of this document was first used when this "Instruction Card" was moved to a left-hand (verso) page. This necessitated rewording "the opposite page" to "the preceding page" (in both cases meaning the Knob Knife Block "Instruction Card"). The present version ("preceding page,") was used later even when this "Instruction Card" was once again on a recto. Tiny details such as this are what makes tech writing fun.

Instructions... 1990-I-W-4Z (Dec. 1943)

"Instructions to Linotype Operators and Machinists." (Brooklyn, NY: Mergenthaler Linotype Company, Sept. 1943.) This particular copy of this edition was issued to Linotype s/n 56,762, a Model 29 equipped with two magazines (four were possible, but you didn't have to have all four fitted).

Aside, the date code of this publication ('I-W', for Sept. 1943) is conclusive evidence that Linotypes were sold during the Second World War. I have such a machine (s/n 56,671, from 1944) and have sometimes been told that it couldn't date from 1944 because no Linotypes were sold then. However, both the serial number lists and the date code of this publication argue that they were.

In this and following entries the icon at left (the picture of the cover) links to a PDF which contains only the front cover and the title page. For the contents, see below.

Note that in the tables of contents below the links may go to copies extracted from other versions. This means that the page numbers, if present, won't always line up correctly.

Instructions... 1990-A-Z-25Z (Jan. 1947)

"Instructions to Linotype Operators and Machinists." (Brooklyn, NY: Mergenthaler Linotype Company, Jan. 1947.) This particular copy of this edition was issued to Linotype s/n 59,478, a Model 32 with 4 main and 4 auxiliary magazines.

This edition is identical with 1990-I-W-4Z (Sept. 1943) except that it contains Electric Pot Micro-Therm Control [With Switch Box] instead of Electric Pot Micro-Therm Control.

"Instructions to Linotype Operators and Machinists." (Brooklyn, NY: Mergenthaler Linotype Company, May 1948.)

This is the first edition that I have which has page numbers.

This edition is similar to 1990-I-W-4Z (Sept. 1943) and 1990-A-Z-25Z (Jan. 1947) except that it contains Electric Pot Micro-Therm Control [With Lighted Switch Box, but No 2-D Wiring Diagrams] instead of earlier versions of this Instruction Card and Linotype Auto-Ejector Set [with stud drawing]. It also contains a trivially different version of the Adv. Knife Block Instruction Card: Quick-Opening Advertising Figure Knife Block ["preceding page" version].

"Instructions to Linotype Operators and Machinists." (Brooklyn, NY: Mergenthaler Linotype Company, Dec. 1949.) This particular copy of this edition was issued to Linotype s/n 63372, a Model 31 with 4 main 90-channel magazines (31-4-90).

This edition has a longer section on the Gas Pot Micro-Therm Control [expanded version]. It omits the "Pot Gas Burner Tips" and the "Pot Mouthpiece Wiper Locking Pin." This reduced length allows it to omit the "Memoranda" as well.

"Instructions to Linotype Operators and Machinists." (Brooklyn, NY: Mergenthaler Linotype Company, Nov. 1950?)

Other than its printing code, this edition is identical to 1990-A-OO-25Z. What makes it unusual is that it appears to mark the switch to a numeric month-year date encoding in its printing code long before other Mergenthaler publications switched to that format ( full numeric month-year codes were not generally adopted until 1967).

Instructions... 1990-10-58-3M (Nov. 1950?)

"Instructions to Linotype Operators and Machinists." (Brooklyn, NY: Mergenthaler Linotype Company, Oct. 1958?)

This edition differs substantially from previous ones reprinted here.

It contains new "Cards" on the The V-Belt Drive Motor and the Mold Cam Lever.

It omits "Lino-Therm Heating Units" and "Quick-Opening Advertising Figure Knife Block" Cards.

It contains a revision of the Mold Slide Safety Card and yet another revision of the Electric Pot Micro-Therm Control Card. Additionally, its versions of the General Instructions and Emerson Motor Cards are slightly revised. The order of the "Thermo-Blo Mold Cooler" and "Mold SLide Safety" Cards is reversed.
