This seldom happens the plants the Ameri- Rolling Mill Co., Middletown, Ohio, and the reasons are found the methods which the management has aided its employees develop their abilities, and thereby realize their ambitions. Promotion within the organization policy consis- tently adhered the company.

Offhand, seems impossible for the management keep intimate, touch with some 10,000 em- ployees; nevertheless effective way doing this has been established.

All the men the organization, from the top the bottom, know the purpose the visits. fact, the men are told the local personnel supervisor that the director employment wants know them and ac- quaint himself with their records that can accu- rately convey the management information their qualifications for more important positions. Whenever promotion made, the director employ- ment sends the works managers, assistant works managers, general superintendents and the heads departments di- rectly concerned letter informing them the change. The letter, bearing the signature the director em- ployment, repro- duced the Armco Bulletin, which goes every employee. Thus “Armco” men are apprized the fact that changes are con- stantly being made within the com- pany and are pro- vided with definite evidence that the management de- sirous reward- ing each employee whose record and ability show that has outstanding merit. How Candidates Are Groomed for Better Jebs means the periodic visits the director employment, well the close contact with the men maintained the local personnel supervisor each plant, the management has presented for its consideration only few selected names when vacancy important position occurs.

Since there are breaks production, the company has been able keep its promises customers and run capacity without interruptions. The attainment this record has been possible only winning the confidence employees and instilling them sense responsibility. They realize that the company cannot hope prosper and estimate the man’s ability, with possible reference the future position for which being trained.

The simultaneous appointment number men new jobs ordinarily would disconcerting the efficiency organization, and the procedure would expensive, but under the Armco system there mini- mum interruption normal activities. The plan appointing superintendent and hiring laborer, because all the men intermediate positions are promoted, has contributed to, rather than detracted from, general effi- ciency. There still another important consideration that has The Iron Age, January 17, 7 March | | | } | least partly determined the management’s adherence the policy just described. promoting its own men, the company has intimate knowledge the qualities and characteristics the employee chosen for each specific undertaking. the other hand, outside man were given responsible position, would take him year two become familiar with the company’s policies the men under him. Since the company’s products are mostly specialties, would have the added disadvantage lacking the right kind experience. Therefore would have the double burden training himself Armco poli- cies and learning the peculiarities the company’s products. not surprising, therefore, that the system employment has lent itself admirably the develop- ment young men who can thoroughly grounded Armco policies. The company has attempted give preference men superior education, experience and training adding its roster employees. This has led the creation “employment reserve,” which functions emer- gency squad filling temporary vacancies the ranks mill employees and from which permanent employees are recruited. Establishment the employment reserve has positions requiring least some small degree skill group men who fit into the regular organization with less than normal amount disturbance. Labor Audit Made Annually Once year the company makes what known labor audit. The record every man reviewed con- ference with his superior and often with his associates. The audit begins with men such rank the general nanager sales, works managers and other division ads, and the discussions the man’s availability for ition considered. After the audit has been completed, the information carded and indexed, and the men are divided into three classes: first, those who are making excellent progress; second, those who are holding their own, but have not made any noticeable advancement; and, third, those who apparently have failed live expectations. the case the latter group, the man- agement attempts learn the reason for the lack prog- ress and often supplies remedy transferring man position better suited his ability and temperament pointing out ways and means which can improve his standing. The annual labor audit and periodic visits the com- pany’s piants enable the director employment keep before him fresh data about every man the organiza- tion. matter how remote man may think his work from the eyes the management, need not fear that his efforts will remain unnoticed. Employment Department Has History Each Worker history card every worker kept file the employment department.

This set plates designed develop the section modulus the beam, and the lengths the plates are determined the amount welding required trans- fer the stresses from beam plate and vice versa. Even this arrangement has decided advantages over the riveted splice proved many thousands these joints use. Yet careful study will reveal that greatly over-designed, and that therefore not eco- nomic, put more correctly, this splice welded cover plates not economical enough. Welding differs fundamentally from other methods joining metals, since the make the joined metals literally one. The ideal weld may therefore described partition metal having all the properties the joined parent metals. Welded splice plates are far from such ideal.

This set plates designed develop the section modulus the beam, and the lengths the plates are determined the amount welding required trans- fer the stresses from beam plate and vice versa. Even this arrangement has decided advantages over the riveted splice proved many thousands these joints use. Yet careful study will reveal that greatly over-designed, and that therefore not eco- nomic, put more correctly, this splice welded cover plates not economical enough. Welding differs fundamentally from other methods joining metals, since the ideal make the joined metals literally one. The ideal weld may therefore described partition metal having all the properties the joined parent metals. Welded splice plates are far from such ideal. The butt joint suggests itself nearer approach; however, presents two major objections: (a) lack ductility, and (b) impossibility developing full strength economically. Thus, two I-beams are butt welded together, directly end end, and then subjected transverse bending, will observed that the deflections are much larger for successive increments loading than for plain unspliced beam the same dimensions similarly loaded.

All failures were caused buckling the upper flange; failures were produced the welds. such studies verify the theory upon which the design this new splice based.

Owing unfavorable price trend for agricultural products does not seem that farm purchasing power quite favorable. Probably, there- fore, the actual requirements for steel December showed moderate de- cline that will bring the composite demand line very close the produc- tion curve, though still remains true that overproduction steel indicated.

The ability the carriers show net income recent months favors larger purchases steel, especially view the economies that have been practised maintenance during the last two years. The prospects for equipment manufacturers are better than year ago, and current reports indicate gains orders for both freight cars and locomotives, which will tend sustain the demand for plates. The outlook for the automobile business favors high rate pro- duction during the first three four months the year, though what will happen thereafter doubtful. The manufacturers are advertising heavily and are offering better values than ever. Export business automobiles continues good. The sharp curtail- ment the latter part 1927 leaves room for continuation expansion for time. still seems, however, that before the year over good many the manufacturers will forced curtail.

Considering the season, and taking the monthly average for the years 1921-1927 100, find the December contracts 120.7, comparison with 124.8 November and June peak 130.9. Thus seems fair say that the trend moderately but distinctly downward. Moreover, contemplated new con- struction December, considering the season, was the lowest since Feb- ruary, 1927. The value plans, reported Dodge Corporation, usually increases December. This time the figure was only $725,000,000, against $931,000,000 November, and $989,000,000 year ago. The trend has been clearly downward since the middle the year. Contracts awarded, too, are high comparison with contemplated new construction. may add that Bradstreet’s building permits show decline 6.9 per cent from November and were nearly per cent under year ago. Fabricated structural steel lettings amounted 243,800 net tons No- vember, which slight increase from October and per cent above the average for the years 1921-1926. Official December figures are not yet available. According weekly trade reports, however, the trend was sharply downward during that month, and both the awards and the pending new projects were small the first week January.

The difference not great, however, and with those exceptions the unfilled orders are the lowest year- end totals many years. Whether such increase occurred was influ- enced price tactics will become more apparent reports following months.
