No. 14224.—14th November, 1901.—THE COMPUTING SCALE COMPANY, a corporation organized and existing under the laws of the State of Ohio, United States of America, and having their principal place of business at Dayton, Ohio aforesaid (assignees of Albert Newton Ozias, of 1822, Tenth Avenue, Minneapolis, Minnesota, United States of America, and Albert Upson Smith, of Saugatuck, Connecticut, United States of America, Gentleman). Improvements in weighing- and price-scales.

———

Extract from Specification.—The present invention has for its primary object the providing of means applicable to all scales employing springs for adjustment of the mechanism or said spring or springs to compensate for the variations in temperature, and by way of illustration it has been shown and described as applied to what is known as a weight-and-price-indicating scale. So far as known, this is the first instance in the art where such means or mechanism has been devised, constructed, or used, and the broader claims thereon are not to be restricted in their scope to any particular or specific form of apparatus, but to all forms embodying means for adjusting the mechanism or the spring to compensate for the different degrees of temperature, however widely they may differ in construction. Further objects of the invention are to improve the details of construction of the scale whereby greater accuracy is secured, the weight and value of the goods more conveniently ascertained, and the manufacture of the scale facilitated.

[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing extract from the specification is inserted instead.]
