Letters Patent No. 85,516, dated January 12, 1869.
IIVIPROVEMENT IN WEIGHING-SCALES.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern.-
Be it known that I, S. S. HAmL'roN, ot' Taylors Falls, in the county of Ghisa-go, and State oi" Minnesota, have invented a new and improved Weighing- Scale; and I do hereby declare that the iollowing is u full, clear, and exact description there-ot', which will enable those skilled in theart to make and use thc same, reference being had to the zicc()mpmiying` drawings, forming part ot' this speciiication, in which- Figure l is a sectional view of my invention, the section being taken through the line o: x, tig. 2.
Figure 2 is a front view ofthe invention, having the 'front of lthe box partially removed, to exhibit the interior mechanism.
Similauletters oi' reference indicato corresponding parts.
The object of this invention is to provide a weighing-scale which is simple, durable, compact, and not liable to get out of repair, and which will indicate, with delicacy and accuracy, the. weight of the article weighed.
The invention consists in the arrangement of parts, as will be hereinafter more fully described.
The weight-lever A isaixcd to the trunnion-rmil a,
The rod a has bearings in the uprightsj j, as shown.
The lug m, forming part of the weight-lever, is pivoted to thc loose plate b, the upper end of which is made concave, for iitting against the cross-bar e, which connects the two uprights d (l at the bottom.
These uprights are connected at thc top b v a similar cross-bar, e', upon which lutter the horns D set, as shown. The said horns are for the purpose of holding the scoop or vessel for containing thc articles to be weighed.
The weight of the substance in the vessel acts, through the-rods (l, in a vertical line, upon the lug in., and raises the lower end of the weigl'it-lcver to that point in the arc of its vibration at which the weightlever and the contents oi' the vessel will beinl cqu'i- Altbr'io.
As the weight-lever is moved from a vertical toward a horizontal position, its dynamic resistance to the weight actuating it becomes greater, in a regularlyincrcasing ratio, and the degree oi"vibration of the weight-lever will correspond to the weightofthe matter acting upon it, so that when connected with a proper scale or pointer, traversing on a graduated limb, the degree of vibration may be made to denote the weight in pounds, and fractions thereof', of the mattei' acting upon the weight-lever.
When the weight hangs vertically, the pivot-centre 'r is not in a vertical line through the tulcrum-centre a, but ou one side of it, the lug m being formed laterally on the weight-lever for that purpose, so thatthe weightlevcr will respond to the weight of the matter acting upon it.
rlhe lower end of thc wright-lover is enlarged to obtain a greater quantity of met-al, to act as a resisting-force to the weight of the matter acting upon it.
The tbrco acting to raise the weight-lever will be 'in equilibrio with the latter at some one point in the arc ot' thc said lcvers mm1-,menu and this point will always be constax-.t for thc saine. weight of matter.
Different weights of matter will raise the weightlever to diiihrent heights in its arcof vibration, and the weight-lerer, once arranged or adjusted to balance a series of increasing weights, will always answer thereafter to the same weight of mat-ter, when placed upon the vessel, resting in the horns D.
To malte the weight-lever indicate the weight of the matter which holds it din equilibrio at any point of its arc oi' motion, the uprights d d are connected with some fixed points, in suitable proximity, by parallel rods l/ g, which are pivoted to the said uprights and to the fixed point-s, which, in this case, are lugs 7L h, forming part of the dial-plate B.
These rods furnish a parallel motion device, to guide the uprights d d in their vertical movement.
These rods y g/ arc connected by cross-braces o o.-
'lhe dial-plate bears any requisite numeral iigures, the position of which on thc graduated face ofthe dial is determined by trial or computation, for cach particular class or size ot' scales, and these adjustments will remain true for any succeeding number of scales, exactly the same as the iirst in construction and proportion of parts.
A pointer, p, traversing around the graduated dial, is connected with th'c weight-lever by means of any suitable interpolation of mechanism which will oscillate the pointer around to a point 011 the dial corresponding tothe position to which the weight-lever has been raised, by the matter in the vessel, on the horns D.
L is a rack, al'i'ixed to the end of' an arm, f, which is al'lixed to or forms part of the uprights Il d.
The ruck engages with a pinion, n, on the shaft s of the pointer, so that, as the rack descends vertically with the downward movement oi' thel uprights (l (I, the pointer will be rotated, and itspoint, when it stops, will indicato, on the graduated dia-l, the number ot' pounds of matter, or fractions thereof, which places the weight-lever tnequilibrio.
The bearings of the shaft s are furnished by the dial-plate and the plate q, forming part of, the plate 'i i, to which the dial-plate is aiixed.
For convenience, the mechanism is atiixed to a box, C G C, Sic., with thc weight-lever swung in the uprightsjj, arising from some part of the said box.
I claim as new, and desire to secure by Letters Patent- 'lhc arrangement of the weight-lever A, trnnionrod c, uprightsj, lug m, and pivoted plate b, with reference to the nprights d d, cross-bar e, parallel rods g, armj, rack l, pinion n, the dial-plate, and the pointer p, as herein described, for the purpose specified.
