The reason for this is that certain defects will show up at a high rate of speed, whereas they would not show up at a lower rate of speed-35 to 40 miles an hour, for instance. After a cabinet is placed on the meters they go to the real inspection in the testing department, where they are tested at a rate of 400 miles an hour for the same reason. The first part of the test is primarily to test the device which is designed to prevent tampering with the record on the inside; the second part of the test is for dead mileage; and the third is to make sure that the drums are working properly and do not hang up in the wrong position. Then, there is a run for the testing of a device consisting of a series of wheels inside the meter which prints on our printed record, which is for the benefit of the cab company. The meter is then run through a stock time test of 10 minutes. When this record is removed and checked, the mileage must figure correctly with the money charges shown, and I can assure you that it does. I can show you records of any number of our tests that figured absolutely accurate, and if there is any variation, it is very slight; over a distance of 3 or 4 miles it is negligible. I do not think I have anything further to say, except that we want to cooperate with this bureau in every way that we possibly can. You realize what we, as manufacturers, are up against in the way of not having some standard specifications throughout the country. The fact that different specifications are required in various parts of the country makes it rather difficult for us, and we will appreciate anything done by the Bureau of Standards toward the standardization of taximeter requirements. The ACTING CHAIRMAN. Are there any other representatives of taximeter companies present who desire to talk on this subject? [After a pause.] If not, we will pass on to the next item on the program, "General consideration of subjects of interest brought up for discussion by delegates." If any of the delegates desire to bring up any questions that have not been under discussion so far, the time is right for it now. Mr. PRIOR. I think it would be well at this time to bring to the attention of the conference the fact that we have with us one of the men who was, I think, one of the originators of this conference, Doctor Reichmann. Doctor REICHMANN. I appreciate being called upon by Mr. Prior, but I have nothing to say. I thank you. (It was moved and seconded at this point that the conference adjourn, the question was taken, and the motion was agreed to.) (Thereupon, at 4 o'clock p. m., the conference adjourned to meet at 9.30 o'clock a. m. Thursday, May 29, 1924.) SEVENTH SESSION (MORNING OF THURSDAY, MAY 29, 1924) The conference reassembled at 10 o'clock a. m., at the Bureau of Standards, William B. MeGrady, first vice-president, in the chair. STATEMENT IN RELATION TO TOLERANCES FOR BREAD LOAVES The ACTING CHAIRMAN. The first number on the program will be the report of the committee on specifications and tolerances on tolerances for bread loaves. Mr. HOLBROOK. The program calls for a report of the committee on specifications and tolerances on this subject. At the time the program was prepared it was hoped that a report could be brought in at this conference, but on account of legal difficulties arising on account of the construction of the Supreme Court decision in the Nebraska bread case it was decided not to attempt to bring in such a report until more mature consideration could be given the matter. Suggestions were made in the papers at the Tuesday morning session, and the committee will direct its efforts to the end that a proper report may be prepared having regard for the Supreme Court decision. The committee is prepared to substitute in heu of the report on bread the report which was placed in your hands yesterday. REPORT OF COMMITTEE ON SPECIFICATIONS AND TOLERANCES ON CHANGES IN CERTAIN SPECIFICATIONS. ANT EXPLANATIONS TRENSON, PRESENTED BY F. S. HOLBROOK, CHAIRMAN. Your committee on specifications and tolerances has been in sessien for some days and has been giving consideration to the various specifications and tolerances adopted from time to time by this confèrence and now in force and effect and recommended by this conference. This one deration has to size extent taken the form of a general renew of the various codes in general as a rest of this review of these steel frations and tences of the conference, your emmittee on speedvations and f the opinion that by serrain rearrangement and demderate speedfeasiers and codes may be committee is especially anxious to have the authority mentioned above granted and to have the amendments recommended given consideration at this time, since it has been advised by the Bureau of Standards that it may be found possible to issue a revised edition of Handbook No. 1 during the year. In this case it is very advisable that the specifications and tolerances be in the best possible form, so that the Handbook may not become obsolete shortly after it is printed. In presenting these changes for your consideration there will, from time to time, be interpolated into the formal report explanatory matter detailing the reasons for the individual changes proposed. LINEAR MEASURES Specification No. 1, under the heading "Linear measures," reads as follows: 1. Measures of length shall be made of a material the form and dimensions of which remain reasonably permanent under normal conditions-for example, steel, brass, hardwood, etc.: Provided, however, That tapes for commercial purposes may be made of cloth, but only when this is wire-woven, and when by this means an actual and sufficient reinforcement and permanency is obtained. * The committee recommends that this specification be amended by striking out that portion of the specification beginning with the words "Provided, however, * *"to the end of the specification. When this specification was first adopted, it was considered that tapes which were actually wire-woven might be developed, so that they would be satisfactory for commercial purposes. This expectation has not been fulfilled, however, and it is our opinion that the so-called "reinforced" tapes can not be considered satisfactory for commercial uses. The proviso is confusing, inasmuch as it seems to suggest that such tapes are procurable, and therefore we recommend that it be stricken out. GLASS GRADUATES Specification No. 7, under the heading "Glass graduates," reads as follows: 7. The graduation marks shall be varied in length in such a manner that they may be conveniently read, but in no case shall any graduation mark extend less than one-fourth of the distance around the graduate. The main graduation marks shall extend at least one-half of the distance around the graduate: Provided, however, That on duplex, or double-scale, graduates a clear space shall be left between the ends of the main graduation marks on the two scales, and this space, measured parallel to the graduation marks, shall conform to the following values: SEVENTH SESSION (MORNING OF THURSDAY, MAY 29, 1924) The conference reassembled at 10 o'clock a. m., at the Bureau of Standards, William B.

REPORT OF COMMITTEE ON SPECIFICATIONS AND TOLERANCES ON CHANGES IN CERTAIN SPECIFICATIONS, AND EXPLANATIONS THEREON, PRESENTED BY F. S. HOLBROOK, CHAIRMAN. Your committee on specifications and tolerances has been in session for some days and has been giving consideration to the various specifications and tolerances adopted from time to time by this conference and now in force and effect and recommended by this conference. This consideration has to some extent taken the form of a general review of the various codes. In general, as a result of this review of these specifications and tolerances of the conference, your committee on specifications_and tolerances is of the opinion that by certain rearrangement and reclassification of the material the specifications and tolerances may be made more readily understandable than is at present the case, and in this way a greater degree of uniformity of interpretation and enforcement throughout the various jurisdictions may be secured. On this account your committee proposes that it be authorized to proceed to make such rearrangement and reclassification without changing the meaning or effect of the present specifications and tolerances. Further, in reviewing the present specifications and tolerances your committee has come to the conclusion that certain amendments should be made in some of them. In some cases your committee is now ready to present specific amendments, which, in its opinion, should be made, and these changes are set out in detail below. Your committee is especially anxious to have the authority mentioned above granted and to have the amendments recommended given consideration at this time, since it has been advised by the Bureau of Standards that it may be found possible to issue a revised edition of Handbook No. 1 during the year. In this case it is very advisable that the specifications and tolerances be in the best possible form, so that the Handbook may not become obsolete shortly after it is printed.
