91.54 Specification card. (a) A specification card, size 8 by 1012 inches, Form No. 4, containing the results of the calculations made in determining the working pressure and other necessary data shall be filed in the office of the chief inspector of locomotive boilers for each locomotive boiler. A copy shall be filed in the office of the chief mechanical officer having charge of the locomotive. Every specification card shall be verified by the oath of the engineer making the calculations, and shall be approved by the chief mechanical officer. These specification cards shall be filed as promptly as thorough examination and accurate calculation will permit. Where accurate drawings of boilers are available, the data for specification card, Form No. 4, may be taken from the drawings, and such specification cards must be completed and forwarded prior to July 1, 1912. Where accurate drawings are not available, the required data must be obtained at the first opportunity when general repairs are made, or when flues are removed. Specification cards must be forwarded within 1 month after examination has been made, and all examinations must be completed and specification cards filed prior to July 1, 1913, flues being removed if necessary to enable the examination to be made before this date.

(b) When any repairs or changes are made which affect the data shown on the specification card a corrected card or an alteration report on an approved form, size 8 by 101⁄2 inches, properly certified to, giving details of such changes, shall be filed within 30 days from the date of their completion. This report should cover:

(1) Application of new barrel sheets or domes.

(2) Application of patches to barrels or domes of boilers or to portion of wrapper sheet of crown bar boilers which is not supported by staybolts.

(3) Longitudinal seam reinforcements.

(4) Changes in size or number of braces, giving maximum stress. (5) Initial application of superheaters, arch or waterbar tubes, giving number and dimensions of tubes.

(6) Changes in number or capacity of safety valves.

Report of patches should be accompanied by a drawing or blue print of the patch, showing its location in regard to the center line of boiler, giving all necessary dimensions, and showing the nature and location of the defect. Patches previously applied should be reported the first time the boiler is stripped to permit an examination.*t [As amended June 9, 1914]

Make working sketch here or attach drawing of longitudinal and circumferential seams used in shell of boiler, indicating on which courses used, and give calculated efficiency of weakest longitudinal seam.

The maximum stresses at the allowed working pressure were found by calculation to be as follows:

Stay bolts at root of thread

lbs. per sq. in. Stay bolts at reduced section lbs. per sq. in. Crown stays or crown bar rivets at root of thread or smallest section, top-lbs. per sq. in. Crown stays or crown bar rivets at root of thread or smallest section, bottom lbs. per sq. in.
