IMPROVEMENT IN WEIGHING-SCALES.
Specification forming part of Letters Patent N0. 198,575, dated December 25, 1877 application filed November 16, 1877.
To all whom it may concern:
Be it known that I, Onnsrnn L. GROWELL, of Rockdale, in the county of Otsego and State of New York, have invented a new and Improved Weighing-Scale, of which the following is a specification:
In the accompanying drawings, Figure 1 represents a side elevation of my improved scale, and Fig. 2 a top View of the same.
Similar letters of reference indicate correspondin g parts.
This invention relates to improvements in weighing-scales, by which the scale-pan is always kept accurately in balance, and any weight placed thereon conveniently read 011'; and the invention consists of a fulcrumed scale-pan support with fixed indicator and rocking-lever arm,in connection with a second rocking lever, having graduated top arm and side arm, with sliding weight for balancing the scale-pan.
Referring to the drawings, A represents an upright supporting standard or post, to the forked top part of which the scale-pan support B is fulcrumed. The scale-pan support B is provided at the front end with a fixed and inclined indicator,O, and at the rear part with a downward-extending lever-arm,D, hav-- ing convex rear face.
The face of the rocking-lever arm D of the scale-pan support bears against a convexlycurved rocking lever, E, that is pivoted by its lower forked parts to bearings of the base of the scale.
A forward-extending top arm, E, with graduated end piece E", passes across scalepan support B, and sidewise of indicator 0, so as to raise, by placing a weight on scalepan, the graduated piece E by the jointaction of the rocking levers D and E. The weight of the load is thus readily read off by the position of the indicator on the graduated piece.
The rocking lever E is also provided with a side arm, F, and sliding weight F, for the purpose of balancing in accurate manner the weight of the scale-pan, and determining thereby the exact weight of the article placed on the scale-pan.
Having thus described my invention, I claim as new and desire to secure by Letters Pat ent A weighingscale consisting of a fulcrumed pan-support, with front indicator and rocking rear lever, in combination with a rocking lever having a top arm with a graduated end piece passing sidewise of indicator, and hav ing also a pan-balancing side arm and slideweight, substantially as set forth.
