Description

F. W McARDLE. SCALE FOR WEIGHING MAIL MATTER.
APPLICATION FILED APR. 25, 1918.
Patented May 18, 1920.
UNITED STATES PATENT OFFICE.
FRED W. MCARDLE, 013 BOSTON, MASSACHUSETTS.
SCALE FOR WEIGHING MAIL-MATTER.
Application filed April 25, 1918.
T0 allcvhom it may concern.-
Be it known that I, FRED W. MGARDLE, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Scales for lVeighing Mail-Matter, of which the fol lowing is a specification.
The object of my invention is to provide an inexpensive and effective device for weighing light articles, such as letters and the like. One novelty of my invention, is the use of a single cord to suspend the device as well as to support the weight.
This and other features will be fully explained in the following symciilcatiou and claim. In the accompanying dra wine's. ure 1 is a face view of the device; 2 is vertical section on the line 22, and Fig. 8 is a transverse section on the line 33. sieferring to the drawings, 10 is a card or plate of rigid sheet material, and of rectangular form; 11 is an eyelet, secured in the card at a point on the vertical axis, above the center of gravity of the card. 12 is another eyelet, secured in the card diagonally above the eyelet 11, the two eyelets being adapted to permit the cord 13 to be passed through both. This cord is formed with a loop 14, one end passing downward on the back side, and the other, downward on the front side of the card, the free ends being passed through the eyelet 11, and knotted or otherwise secured at their crossing point, 15, thus providing a loop by means of which the card may be suspended from the eyelet 11. The free ends of the cord are extended to pass through the eyelet 12, one end, 16 passing through to the back side of the card and being formed with the loop 17, by knotting or other means of securing at 18. The other end is passed through the eyelet 12, from the back side to the front of the card and similarly formed with the loop 20 by securing at 21. 'A segment 22, concentric with the eyelet 11, is printed or engraved on the face of the card 10, and serves as a register, the cord 13 acting as a marker to indicate the weight of the article supported by the loops 17 and 20 Specification of Letters Patent.
Patented May 18, 1920.
Serial No. 230,701.
when the device is suspended from the loop let. The use of both loops for supporting the article to be weighed, insures a two point support, thus preventing the tendency of the article to swing or to slip out of position if supported by one loop only but it will be obvious from the description, that either loop may be used to support an article or both may be used to support two articles to be weighed. The weight of the article or articles suspended from the loops 17 and 21, acting on the eyelet 12, tends to rotate the card about the point of suspension, 11, and the weight is indicated on the segment in ounces, the marking lines 23 alining with the cord 13 to give a reading. As the eyelet 11 is situated above the center of gravity of the card, there is a preponderance of weight on the lower portion, which operates to return the card to normal position 24 when the article being weighed, is removed from the loops, the 0 mark on the segment alining with the cord 13.
Having described my invention, I claim A weighing device consisting of a rectangular plate of thin, rigid material having two perforations; a cord formed with a loop, the free ends of which are passed in opposite directions through one of the perforations, located at a point on the vertical axis, above the center of gravity of the card, are knotted or otherwise confined at their junction, and are passed through the second perforation, located at one side of and diagonally above the first perforation; each end being formed into a loop for the purpose of supportin an article laid within the loops; means for indicating the weight of the article by the registration of a portion of the cord with scale graduations marked on the card; the reading to be taken when the device, together with the article to be weighed, supported in the end loops, is suspended from the loop passing through the point of suspension, as described.
In testimony whereof I have affixed my signature.
FRED MoARDLE.
