WASHING BOILERS

§ 91.45 Time of washing.

All boilers shall be thoroughly washed as often as the water conditions require, but not less frequently than once each month. All boilers shall be considered as having been in continuous service between washouts unless the dates of the days that the boiler was out of service are properly certified on washout reports and the report of inspection.

§ 91.46 Plugs to be removed.

When boilers are washed, all washout, arch, and water bar plugs must be removed.

§ 91.47 Water tubes.

Special attention must be given the arch and water bar tubes to see that they are free from scale and sediment.

An accurate record of all locomotive boiler washouts shall be kept in the office of the railroad company. The following information must be entered on the day that the boiler is washed:

(a) Number of locomotive. (b) Date of washout.

(c) Signature of boiler washer or inspector.

(d) Statement that spindles of gauge cocks and water-glass cocks were removed and cocks cleaned.

(e) Signature of the boiler inspector or the employee who removed the spindles and cleaned the cocks.

If a serious leak develops under the lagging, an examination must be made and the leak located. If the leak is found to be due to a crack in the shell or to any other defect which may reduce safety, the boiler must be taken out of service at once, thoroughly repaired, and reported to be in satisfactory condition before it is returned to service.

§ 91.50 Leaks in front of enginemen.

All steam valves, cocks, and joints, studs, bolts, and seams shall be kept in such repair that they will not emit steam in front of the enginemen, so as to obscure their vision.

§ 91.53 Reports of tests.

Not less than once each year and within 10 days after hydrostatic and other required tests have been completed a report of such tests showing general condition of the boiler and repairs made shall be submitted on Form No. 3,1 size 6 by 9 inches, and filed with the district inspector of locomotive boilers, and a copy shall be filed in the office of the chief mechanical officer having charge of the locomotive. The monthly report will not be required for the month in which this report is filed.

NOTE: Samples of boiler forms 1, 3, and 4 indicating exact size, color, weight, and grade of paper will be furnished on application by the Interstate Commerce Commission. Form No. 3

ANNUAL LOCOMOTIVE INSPECTION AND

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 ments.

reinforce

(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 blueprint 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.

Extract from Rule 54 of the Rules and Instructions for Inspection and Testing of Locomotive Boilers and their Appurtenances:

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 10% inches, properly certified to, giving details of such changes shall be filled within 30 days from the date of their completion. This report should cover

A. Application of new barrel sheets or domes.

B. 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.

C. Longitudinal seam reinforcements.

D. Changes in size or number of braces, giving maximum stress.

E. Initial application of superheaters, arch or water-bar tubes, giving number and dimensions of tubes.

F. 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 the 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.

INSTRUCTIONS FOR PREPARING FORM

Describe accurately what alterations were made.

The location and extent of cracks, pitting, corrosion, and grooving must be shown and dimensioned unless the defective plate is removed.

Drawing must show whether the plate underneath patch was removed.

Report must state whether iron or steel rivets were used.

The size of rivet holes must be given as well as the size of the rivets.

If authentic records of the tests of material used in making repairs can be obtained, the lowest tensile strength as shown by the test must be given; otherwise 50,000 pounds for steel and 45,000 pounds for wrought iron will be allowed as provided by rule 4.

In case of patches applied prior to July 9, 1914, if there is no authentic record of the date when or the shop where the alteration was made, insert the word "Unknown" in the proper blank spaces.

It is not necessary to report patches on surfaces supported by staybolts.
