TESTIMONIALS.

15. Applicants must (except where otherwise specially provided) send with their application form and fee testimonials signed by their employers, and such documents must state clearly and distinctly the class of engines and boilers the applicants have been in charge of, and the dates of beginning and ending of their service. The diameter of the cylinder or cylinders of the engines, and the horse-power of boilers, must also be clearly stated in such testimonials. In cases where applicants are unable, from any sufficient cause, to produce employers’ testimonials, a statutory declaration verifying the facts may be accepted by the Board of Examiners.

16. In all cases the applicants must send with their application form, fee, and employers’ testimonials a certificate of sobriety and good conduct for a period of at least twelve months immediately preceding the date of application.

17. The certificates to be issued by the Board of Examiners are (1) “Competency,” upon examination, and (2) “Service,” upon proof of service as set out in the said Act, for drivers of steam-engines the area of the cylinders of which exceeds 144 circular inches, and of boilers exceeding 15-horse power. Such certificates are of the grades set forth in the said Act.

18. “Circular inches” means the diameter of the cylinder in inches multiplied by itself, thus: 12 in. diameter is multiplied by 12, and equals 144 circular inches.

EXTRA FIRST-CLASS ENGINEER. COMPETENCY (ONLY).

19. This certificate entitles the holder to drive and have charge of any steam stationary engine and boilers other than winding-engines.

20. An applicant for examination as an extra first-class engineer for taking charge of stationary engines must—

(1.) Be at least twenty-one years of age.

(2.) Be the holder of a first-class stationary-engine driver’s certificate.

(3.) Produce satisfactory proof of having worked as an apprentice for at least five years in a workshop or workshops where engines are manufactured or repaired, or where work of a similar character is performed.

(4.) Produce testimonial referred to in paragraph 16, and forward fee of £1 to the Chief Inspector of Machinery, Wellington.

(5.) Be proficient in the mensuration of superficies and solids, the extraction of square and cube roots.

(6.) Give a correct description of any class of stationary engine and of all classes of stationary boilers used on land, and be able to calculate the strength of any part of such engine and boiler, and understand their construction.

(7.) Show clearly how defects in engines and boilers, either from natural decay or corrosion, should be remedied.

(8.) Possess a creditable knowledge of the prominent facts relating to combustion, heat, and temperature problems.

(9.) Be able to calculate indicator cards, and draw proper conclusions from cards to be given to him by the Examiner, and answer questions relative to the adjustment of slide-valves and eccentrics.

(10.) Work out lever, dead-weight, spring balance, and direct spring safety valves, and calculate the size of steel, &c., in the latter case.

(11.) Work out questions relative to strength of copper, cast-iron, or steel pipes, strength of shafting, and questions generally that may arise regarding strength of parts of machinery that he might be called upon to take charge of in the event of his becoming an extra first-class engineer.

(12.) Be able to make a hand sketch, without a copy, of any part of an engine or boiler, and fill in sizes of same, so that the part could be made from such sketch. This need not necessarily be an elaborate sketch, but clear as to size and details.

FIRST-CLASS ENGINE-DRIVER. (COMPETENCY.)

21. This certificate entitles the holder to drive and have charge of any steam stationary engine and boiler, except a winding-engine.

22. An applicant for examination as a first-class engine-driver for taking charge of stationary engines must—

(1.) Be at least twenty years of age.

(2.) Produce testimonials referred to in paragraphs 15 and 16, and forward fee of £1 to the Chief Inspector of Machinery, Wellington.

(3.) Have been in possession of a second-class engine-driver’s certificate for twelve months, and having efficiently driven an engine the cylinder-area of which exceeds 144 circular inches, but does not exceed 200 circular inches, while holding a second-class stationary-engine driver’s certificate;

(4.) Or at any time having had actual charge of a boiler over 15-horse power for a period of not less than twelve months while holding a second-class stationary-engine driver’s certificate;

(5.) Or having passed an examination for second-class engine-driver, and having been in charge of an engine the cylinder or combined cylinders of which exceed in area 144 circular inches for a period of not less than three years previous to receiving a second-class certificate, shall without further service be entitled to be examined for a first-class certificate;

(6.) Or produce satisfactory proof of having served four years’ apprenticeship in a workshop or workshops where engines are made or repaired, or where work of a similar character is performed;

(7.) Or of having been employed for three years as a journeyman mechanic in a workshop or workshops where engines are made or repaired, or where work of a similar character is performed.

(8.) Be able to work out questions in arithmetic, such as addition, subtraction, multiplication, division, and proportion, the working-out of a lever safety valve (area of valve being given), and simple questions relating to quantities of coal contained in bunkers, oil-tank capacity, and consumption of stores.

(9.) Understand the principle of steam-engines much more fully than in the examination for second-class certificates, how steam performs its work, and answer questions generally dealing with the details of engines.

(10.) Explain how the defects in engines, either from natural decay or corrosion, should be overcome.
