13. Every Convention application shall contain a declaration that foreign application has been made for protection of the invention to which such Convention application relates, and shall specify the country or countries in which such foreign applications have been made, and the official date or dates of those applications respectively. The application must be made within twelve months from the date of the first foreign application, and must be accompanied by a complete specification, and signed by the person or persons by whom such first foreign application was made. If such person or any of such persons is dead, the application must be signed by the legal representative of such dead person, as well as by the other applicants, if any.

14. In addition to the specification left with every Convention application, a copy or copies of the specification or specifications and drawings or documents filed or deposited by the applicant in respect of the first foreign application, duly certified by the official chief or head of the Patent Office of the country in which such first foreign application was made, or otherwise verified to the satisfaction of the Registrar, must be left at the Office at the same time as the application, or within such further time thereafter as the Registrar may allow. If any specification or other document relating to the application is in a foreign language, a translation thereof shall be annexed thereto and verified by statutory declaration or otherwise to the satisfaction of the Registrar.

There shall be indorsed on every patent granted in pursuance of a convention application a statement as to the date of the first foreign application in respect of the invention, and the name of the country in which that application was made.

15. Save as aforesaid and as provided by Regulation 53 hereof, all proceedings in connection with a Convention application shall be taken within the times and in the manner prescribed by the said Act or these regulations for ordinary applications.

DRAWINGS.

16. Drawings, when furnished, should accompany the provisional or complete specification to which they refer, except in the case provided for by Regulation 21 hereof. No drawing or sketch such as would require the preparation for the printer of a special illustration for use in the letterpress of the specification when printed should appear in the specification itself.

17. Drawings may be made by hand, or lithographed, printed, &c. They must be made on pure-white hot-pressed rolled or calendered strong paper of smooth surface, good quality and medium thickness, and measuring 13 inches in length by either 8 inches or 16 inches in width. They must be made without washes or colours, in such a way as to admit of being clearly reproduced on a reduced scale by photography. Mounted drawings must not be used.

18. Drawings must be prepared in accordance with the following requirements:—

(a.) They must be executed with absolutely black ink. Only indian ink of the best quality should be used.

(b.) Each line must be firmly and evenly drawn, sharply defined, and of the same strength throughout.

(c.) Section-lines, lines for effect, and shading-lines should be as few as possible, and must not be closely drawn.

(d.) Shading-lines must not contrast too much in thickness with the general lines of the drawing.

(e.) Sections and shading should not be represented by solid black or washes.

(f.) They should be on a scale sufficiently large to show the invention clearly, and only so much of the apparatus, machine, &c., should appear as effects this purpose. If the scale is given, it should be drawn, and not denoted by words.

Reference letters and figures, and index numerals used in conjunction therewith, must be bold and distinct, and not less than ⅛ inch in height. The same letters should be used in different views of the same parts. Where the reference letters are shown outside the figure they must be connected with the parts referred to by fine lines.

19. A fac-simile or “true copy” of the drawings on tracing-cloth, but otherwise in accordance with the foregoing regulations, should be filed at the same time as the original drawings.

20. Drawings must be signed by the applicant or his agent in the right-hand bottom corner. Neither the title of the invention nor any descriptive matter should appear on the drawings, and they should be delivered at the Office free from folds, breaks, or creases.

21. If an applicant desires to adopt the drawings lodged with his provisional specification as the drawings or part of the drawings for his complete specification, he should refer to them in the complete specification as those left with the provisional specification.

CHEMICAL SAMPLES AND SPECIMENS. MODELS.

22. Where samples of ingredients are required by the Registrar, they must be contained in glass bottles properly secured; but dangerous or explosive substances must not be sent. Models, which may be lodged from a time to be notified in the Journal, must be neat and workmanlike, and of a size not exceeding 12 inches on the longest side, unless otherwise allowed. Models and bottles furnished in pursuance of this regulation must bear the name of the inventor, the title of the invention, and the date of the application, and be furnished to the Office free of charge and in good order.
