Testimonials.

17. 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.

18. 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.

Certificates to be granted.

19. The certificates to be issued by the Board of Examiners are (1) “Competency,” upon examination, and (2) “Service,” upon proof of service, for drivers of steam stationary 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.

20. Circular inches mean the diameter of the cylinder in inches multiplied by itself, thus: 12in. diameter is multiplied by 12, and equals 144 circular inches.

Class A (1). Extra First-class Engineer. Competency (only).

21. This certificate entitles the holder to drive and have charge of any steam stationary engine and boilers.

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

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

(4.) Produce testimonial referred to in paragraph 18.

(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, 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.

Class A (2). First-class Engine-driver. (Competency.)

23. This certificate entitles the holder to drive and have charge of any steam stationary engine and boiler.

(7.) Understand the principles 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.

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

(9.) Explain the different classes of boilers met with on land, how they are put together and stayed, and explain how defects that might arise in the working of boilers should be overcome, in a much fuller manner than in the examination for second-class certificates.

(10.) Be able to make a simple, intelligible hand sketch of any of the working parts of steam-engines and boilers.

Class A (3). Second-class Engine-driver. (Competency.)

25. This certificate entitles the holder to drive and have charge of any steam stationary engine the area of cylinder or combined area of cylinders of which does not exceed 200 circular inches, and of its boilers, and of any steam-boiler to which no machinery is attached.
