Cleanliness and Production

There are those who may question the need for emphasis being placed upon Cleanliness in the maintenance and operation of the Linotype. To such it should be said that a cleanly kept Linotype is a better operating machine for it. Dirt never helps any machine. In a machine which is designed and built to deliver a product whose measurements must be as uniformly accurate as Linotype slugs all dust and dirt should be regularly removed.

Cleanliness is a necessity, if uninterrupted production is expected. A clean, well-maintained Linotype and a clean proof are the measure of craftsmanship.

"Carelessness does more harm
than a want of knowledge!"

-BENJAMIN FRANKLIN

For more than half a century LINOTYPE has maintained a policy of sharing the technical experience of engineers, plant machinists, and operators with Linotype users everywhere. The Linotype Life Extension series of booklets, of which this is one, has been compiled and distributed in the interest of maximum production with minimum waste and delay through continuous, uninterrupted operation.

The productive life of mechanical equipment is dependent upon the treatment it is accorded more than upon all other factors combined.

Invariably, serious mechanical troubles are the result of minor items, most of which could have been corrected before they became major difficulties. Linotype servicemen know that most of the causes of mechanical breakdowns could have been averted if the user had maintained a regular schedule of checkups, reasonable cleanliness and proper lubrication.

Hence, this series of Linotype booklets, devoted to conservation of machines and equipment -Linotype Life Extension, emphasizes the value of a careful program of maintenance. Routine checkups should be as much a part of Linotype operation as seeing that metal is in the metal pot and copy on the copy holder.

A routine program adaptable for small and medium plants is here suggested which should assure satisfactory operating conditions and well-kept equipment.

NOTE: For location. of lubricating points and recommended lubricants, consult the instructions and illustrations in the second section of this booklet. For machine adjustments and mechanical descriptions of functions, see the official Linotype manual, "LINOTYPE MACHINE PRINCIPLES:" This is a 487-page completely indexed book which can be procured at any Linotype agency. Price $3.50 postpaid to any part of the United States (X-1752).

Schedule for Large Battery of Linotypes

Large batteries of Linotypes, in plants where several machinists are employed, usually receive systematic checkups in addition to normal operating supervision. Quite naturally, there are various methods employed to accomplish these ends and it would be impossible to say that any one system would be best for all plants.

Nevertheless, one of the most effective schedules noted was developed by Alexander Gordon, late Linotype head-machinist of the Evening Star, Washington, D. C. This schedule of work which has been published and. widely distributed, has been adapted by many large plants to their individual requirements and is printed here for that purpose. It will be noted that the night machinists are responsible for routine repair and maintenance. In addition to this regular schedule any special work which is required to be done on specific machines is indicated in writing, in spaces provided on the blank that is left for the machinists each night. Any comments they may make are written on the reverse of the blank, which thus becomes a report to keep the head machinist informed.

NOTE: An afternoon paper; between 40 and 50 Linotypes, with full day crew and varying night force

The above are EVERY DAY "MUSTS"

One Machine Each Day

Schedule of Night Work

NOTE: The illustrations appearing on the following pages indicate the oiling points of Models 29,30,31 and 32 and the Self-Quadder. However, they will be found helpful in lubricating other models.

To insure a long life of efficient and trouble-free operation, a systematic plan of machine maintenance should be followed. In this plan, proper lubrication is the most important single factor. So that this may be accomplished in a thorough and systematic manner, there are indicated in the following photographs all of the various oiling points on the machine. In some cases two or more oil holes are shown in one location, and are indicated as (2).

The oil holes are placed in the most convenient and accessible positions practicable. It should be remembered that a few drops of oil applied frequently is more economical and much more efficient than flooding the parts with oil occasionally. In addition to wasting oil, flooding only helps to collect dirt, and in all probability does more harm than good. A piece of waste or cloth should be used to remove all surplus oil from around holes after oiling. Extreme care should be used to prevent any oil from coming in contact with the matrices as it will eventually hinder smooth assembling action.

It is not possible to indicate the desirable frequency, of oiling individual points on the Linotype, as is practicable in the case of an automobile. The widely varying conditions under which Linotypes are operated, with respect to running time, cleanliness and climate, combine to make it a problem best solved locally, through the exercise of simple mechanical judgment. It should be sufficient to point t out that the constantly moving parts call for more frequent attention than those which only contact when the machine makes its periodic cycles.

Particularly important to proper lubrication is the quality of the lubricant. Cheap vegetable oils are a false economy. Always use high-grade machine oils that will not gum. We recommend Linotype oil and grease as it has been thoroughly tested and found efficient. As a guide, with regard to quality and viscosity, we have indicated throughout, by symbol, the proper lubricant for each oiling point. As will be noted, the proper grade oil in the majority of places is our X-24, a medium-weight motor oil (standard S.A.E.20)
