postal scale, rule & letter opener

"Right Weigh" letter scale

This combined letter scale, rule and letter opener is a design of James King Richie of Butler, Pennsylvania, U.S.A. A patent application was made on December 6, 1923. Finally, the design was patented on March 29, 1927. The American patent number is 1,622,924. This specimen differs on details from the drawings presented in the patent. The patent was made for a combined postal scale and rule. The letter opener function is not part of the patent. This postal scale was a present of the Guaranty Trust Company of

the three patent figures

Pittsburg, Pennsylvania. The name "RIGHT WEIGH" is on the postal scale. Also the text: Pat. apl. for J.K. Richie Butler, PA. is engraved. So, most likely this postal scale dates from the period 1923-1927. The postal rate for letters of 2c per 1 ounce was valid in the period July 1, 1919 till July 6, 1932. The letter clip is not original. It was made by me with figure 3 of the patent as example. The weighing capacity is 3 ounces, the scale of the rule is 6 inches long. The overall length is 7 3/16 inch (18.3 centimeters). The material probably is brass. Below some more pictures of this letter scale.
