Description

UNITED STATES POSTAG E SCALE.
sPEorFIcATIoN forming part of Letters Application filed August 9, 1899.
T0 at whom it may concern.-
Be it known that 1, CHARLES F. RITOHEL, a citizen of the United States of America, and a resident of Bridgeport, county of Fairfield, State of Connecticut, have invented certain new and useful Improvements in Postage- Scales, of which the following is a specification.
My invention consists of an improved construction of scales for weighin g pieces of mailmatter and indicating the postage required, whereby it is designed to provide simpler and cheaper scales than the scales of ordinary construction, as hereinafter described, reference being made to the accompanying drawings, in which Figure 1 is afront elevation of my improved scale with a part of thefront plate broken out. Fig. 2 is a sectional elevation of the case on line 2 2 of Fig. 1. Fig. 3 is a transverse section on line 3 3, Fig. 1; and Fig. i is a side elevation of the spring detached from the other parts.
I make a case of sheet metal or other suitable material, comprising two parallel side plates a, joined at the edges Z) in any suitable way to afford a space comparatively broad in one way and narrow transversely, the space between the sides being only wide enough to receive a thin plate 01 and a zigzag wire spring e, said plate (1 being of suitable breadth to carry, say; three columns of numerals, as f g h, for indicating through the sight-openings M or at the lower end of the case the amounts of postage required for, say, first, second, and third class mail-matter.
The spring is constructed in the zigzag form to adapt it to work in the narrow case. The upper end is attached to the case at l, and the lower end is connected to the plate at art, so as to suspend the plate within the case with. its lower end normally about the altitude of the lower end of the case. The loops of the spring are pinched together for some distance from the extremities, as shown at 'n, in a way to stifien themand limit the flexing in the expanding and contracting actions of use to the parts of the wire intermediate of the Patent No. 655,350, dated August '7, 1900.
Serial No. 726,669. (No model.)
pinched parts, or mainly so, whereby concentrated action at the bends, which would otherwise occur and would sooner affect the in tegrity of the spring, is avoided and the tion as to be a practically satisfactory weigh ing-spring of durable quality.
The upper end of plate cl has a suitable scale-pan 0 for holding pieces of mail to be weighed, and the lower end of the case is pro vid ed with legs 19 or any other suitable supporting-base. In practice the legs may be formed of integral strips or prongs of the side plates of the case suitably bent apart for the required breadth of; supporting-base.
Such scales may of course be employed for weighing any other articles, the registering characters being graduated according to the requirements of the case.
What I claim as my invention is 1. The combination in a weighing-scale, of the upright case composed of two side plates joined at the edges so as to provide a narrow space between them, and having supportinglegs, pan-supporting plate adapted to move up and down in said case, and the zigzag wire spring placed between said plate and one side of the case and suspending said pansupporting plate in said case, the loops of the spring being pinched together a measurable distance from the bends.
- 2. The combination in a weighing-scale, of the upright case composed of two side plates joined at the edges so as to provide a narrow space between them and having integral supporting-legs, pan-supporting plate adapted to move up and down in said case, and the zigzag wire spring placed between said plate and one side of the case and suspending said pan-supporting plate in said case, said pansupporting plate having one or more columns of weight-indicating numerals.
Signed by me at New York, N. Y., this 26th day of July, 1899. I
