IMPROVEMENT IN BALANGES.

To am. WHoM 1T MAY conceals;-

Be'it knownthat I, IRA BISBEE, ofl Richmond, in the 4county oi' Ray, and State of Missouri, have-invented a newand useful Improvement in Scales; and I-do hereby declare the Vfol-lowing to be a full, clear, and exact description ofthe nature thereof, which will enable others, skilled in the art to which it applies, to fully understand and use the same, reference being had to the accompanying drawings mak-ing part of this specification, which represents'a'side'view of the device illustratingmy invention. y

This invention consists in a scale constructed with a disk or circular plate, mounted at its centre upon a suitable stand, and having receiving-plates or basinssuspeuded at corresponding sides of thedisk at proper points, andalso having both sides graduated alike, whereby both graduations will register with each other, so

vthatthe weight canYbe-viewed by the buyer and seller simultaneously. My inventionfurther consists in having the plate marked with weights of various denominations, viz, troy, apothecaries, `and avoirdupcis; also for letters, and American and foreign coins of variousdenominaticns. I

In the drawings, A represents the hase or foundation, from which rise two standards, B. On the 'upper end of these standards is mounted a concentric disk or circular plate, C, by 'gndgeons or bearings a. This-plate is cut away at two sides, as shown at a', so as to allow the Aswing of the receiving-plates or basins D, which are suspended from arms e, whose inner ends are secured to the plate. I prefer to cut away the portion as shown, althoughit is notv extremely necessary, for this may be dispensed with, and the arms he'extended or project farther from the plate, and the basins or plates connected therewith, as shown. Thelowest part ofthe plate has firmly vsecured to it an equipoise or weight, E, which ca usesthe return of the plate to its normal position, and to act in connection with the graduations on the plate and be the weighing-medium. Each side of the stand- 4ards B beurs theends of an upright index or pointer, F, which straddles the plate so that it will mark or note the weight on both sides. As a modification ot'- this, the index or pointer may be secured to the plate, and will swing over a stationary dial which may be mounted ontho standard or frame, or Ain any equivalent manner. The ,plate Chas its graduations onboth sides of the same. These graduations are of troy, apothecaries, and avoirdnpois weights, of. letters, and of various'. coins of .American and foreign countries. A pound weight, as shown on one'side ofthe plate, will also be seen on the opposite side, and so with any other weight. The great advantage of this is, that the buyer can see exactly what weight he is getting, whether the seller informs correctly or not, so that the'former can -be cheeked bythe latter in any attempt to cheat, or state a false amount. It is well known to all that sellers will throw articles on the scale, and the weight thereof and the momentum ofthe force will cause the index or pointer to sweep or travcrse'a greater distance than what it would when in avstate of rest, and then call ont the amount prfoportionately. l I desire'toA obviate this evil, and so have constructed my device. The straddling-index will allow both sides to be viewed, and as they are graduated to register with each other, it is evident that' there will be no diliiculty in the buyer observing the full motion of the plate.

When gold 0r silver is to be weighed, thescale can be made small, althoughit will work equally well ifon a large plan,for if the limit ofthe scale were one pound troy, and it be desired to weigh two pounds, one basin or receiving-plate can receive a quantity equal to one pound, andrwhen this is weighed it will only be necessary to iillthe other basin until the weight of the other is entirely overcome, and the scale be evenly balanced; and so with larger weights, a double 'quantity is thus weighed.

The equipoise E, at\ the bottom ofthe plate, is firmly secured thereto, so that in operating the scale there l will he novibratiou thereof, as would be the case if it were pivoted or swung on its bearing. Besides this, the weight will act in connection with the graduations and' be the weighing-medium, for the further that it be swung from its place of rest, the greater will be the weight it will weigh, und the graduation and equipoise will be adjusted nicely relatively to each other. It will be seen that the standards- B will be the indexes or pointers" for the lower partof the disk.

The simplicity of the device is apparent. For miners purposes it .will present a great usein overcoming the objections to separate weights, which are apt to be lost or misplaced in transportation, or changing in size or wear.

I have combined the weights andscale, and have no complicated parts liable to break or get out of order or be unnecessarily detached.

Having thus described my invention, what I claim as new, and desire to secure by LettersPateut, is-

1. A scale consisting of the concentric disk C, having graduations on both sides, registering with each other, the equipoise E rmly secured thereto, and the suspended basins or plates D, substantially as represented and described.

2.. The disk C, having graduatious on both sides, registering with each other, whereby they can ybe viewed simultaneously, as representedand described.

8. A scale having the following characteristics, viz, graduations for troy, ap'otliecaries, and avoirdupois weights, for letters, and for American and foreign coins, substantially as represented and described.v

The above specification of my improvement in'scales, signed this eighth day of April, 186'?. y
