Opinion

HOUGH, District Judge.

Mr. Farrell, in his capacity as superintendent of weights and measures of this state, has promulgated the following rule;

“Automatic Computing Scales.
“All combination spring and lever computing scales must be equipped with a device which will automatically compensate for changes of temperature at zero balance, and throughout the whole range of weight gradations.”

The scale referred to is “spring,” because the load of the article to be weighed stretches an elastic (usually a helical) coil of steel, which in turn operates an indicator that comes to rest over figures indicative of weight; it is “lever,” because the spring is directly affected by a lever on which the thing weighed proximately operates; it is “combination,” because the spring and lever are united in the mechanism; and it is “computing,” because the indicator apparatus is so arranged that, within the limits of weights and prices for which it is contrived, one glance at a printed card, which is part thereof, shows, e. g., not only that the customer has obtained 9J/3 pounds of something, but what he owes for it at 8 cents a pound.

In any contrivance which depends for efficiency upon the elasticity of metal, there is an element of error introduced by changes of temperature. In such an apparatus as the scale under consideration a popular description of such capacity for error is to say that the spring “stiffens up” in cold weather and relaxes or loosens in warm weather. When a computing scale ultimately depends for its proper function upon such a spring, it is obvious that an erroneous weight produces an increasingly erroneous price, as the amount bought becomes greater.

Even if the percentage of error for all weights within the capacity [88]*88of the scale remains constant (which is not always the case), most springs will stretch more in proportion for the first few pounds of weight applied to them than for the last pounds for which they are designed. From this it follows that (for example), if a computing scale be designed for weights up to 40 pounds and prices up to $1 a pound, the lines on the indicator chart will grow closer together as the limit of weight or price, or both, is approached. Therefore, even with a constant percentage of error through the whole range of operations, the proportionate amount of indicated untruth may grow greater as the weight increases. There are many other reasons why a spring scale, or any other scale, may develop inaccuracy, besides changes of temperature. Upon them it is unnecessary to dwell. There is such a thing as automatic compensation for error induced by temperature variations. The only compensating method shown to the court is covered by a patent and owned by a scale manufacturing company. It functions by using the different rate of contraction or expansion of different metals to produce less or more tension upon the weighing spring as the condition of the thermometer may require; the scale being balanced and adjusted at a given temperature with the com'pensating metals in known positions.

So far as shown, this method of compensation is accurate, but slow; that is to say, it will take perhaps some hours to get a scale, which has gone wrong through a drop in the temperature of say 30 degrees, to again become accurate. But it is impossible to prevent the operation of this automatic corrector, except by such crude devices as inserting a bar or stick in the scale to' prevent its operating at all.

The complainant has no automatic compensation upon its scale, but it has a mechanical compensator. The fact that the scale is no longer true is shown by an examination of the indicator card. If that error is caused by expansion or relaxation of the spring, it can be corrected by increasing or diminishing the tension upon that spring, by turning a screw. This correction can be made instantly, and in the hands of an honest and even reasonably intelligent owner I see no reason why complainant’s scale is not as good, and more easily corrected, than a machine containing an automatic device of the kind above roughly described.

But it is also proven to be true that the same mechanical device with which an honest man will correct complainant’s scale for variations caused by temperature can be easily used by a dishonest, or perhaps even an ignorant, owner to apparently correct inaccuracies of the scale which have no relation whatever to atmospheric change. The same turn of the same screw which properly produces correspondence between two marks on the indicator face after a sudden drop or rise of temperature will also produce an apparent correctness when the temperature has remained 'constant, but (for example) the spring has suddenly and permanently weakened.

It is therefore true (and this is found to be the basis or reason for defendant’s action) that a spring scale without automatic compensation for atmospheric changes is more easily and with less likelihood of detection manipulated against a customer than is a similar scale with automatic protection.

[89]*89The theory of this hill is simple, and single, viz.: That the superintendent’s rule as above quoted is an invalid (i. e., unconstitutional) attempted exercise of the police power, in that it unjustly discriminates between the complainant’s scale and the scales of other manufacturers. Section 10, art. 1, Constitution U. S. It is alleged also to violate the Fourteenth Amendment of said Constitution, and to interfere with interstate commerce. The prayer of the bill puts in a considerable variety of ways the demand that defendant cease to interfere with or prevent “county sealers” from bestowing approbation upon complainant’s scales.

What has actually happened is this: There is a considerable body of statute law in New York relating to weights and measures. By that law the offices of county and city “sealers” are established. These officials are not appointed by the defendant, nor removable by him. They are charged with the duty (inter alia) of examining weights and measures within their cities or counties at stated intervals, and when the same are- found to correspond with the state standards the sealers “shall seal and mark such weights and measures with the appropriate devices.” General Business Law, art. 2, § 15, as amended in 1910 (Laws 1910, c. 187).

It is not obligatory upon the defendant to seal anything, though he must at least once in two years visit the various cities and .counties of the state, (either personally or by deputy) and inspect the work of the local sealers, and in the performance of this duty of inspection “he may inspect the weights, measures, balances or any other weighing or measuring appliances of any person, firm or corporation.” Section 11. But no where in the statutes is there to1 be found any specific. authorization conferred upon the state superintendent permitting him to give definite and detailed instructions to city and county sealers as to what particular form of weighing or measuring device they shall approve or shall disapprove.

It is proven (human nature being what it is) that the official seal placed by local sealers upon this or that weighing or measuring apparatus is looked upon with great respect by the purchasing community, whether that phrase means the persons who buy scales or those who buy what is weighed. It is a very serious handicap upon, if not almost a complete prohibition of, successful selling of any given scale in the state of New York, that it cannot obtain the approval of the local sealers.
