Speci'eation forming partof Letters Patent N 6,194, dated vMarch 20, 1849.

Beit known that we, TILLY FLINT, of Westford, and VARREN FLINT, of Chelmsford, in the county of Middlesexl and State of Massaehnsetts, have invented e new and useful Improvement' in the Steelyarddalance for Weighingg and we dohereby declare that the saine is fully described and ,represented in the 'following specification and accompanying drawings, letters, figures, and references thereof.

In the said drawings, Figure 1 represents an4 elevation o fone side'of our improved-steelyardbalanee and its supportingframe., Fig. 2 is an elevation of the opposite'sideof the same. Fi gf is an end elevationio'f the saine.

In the drawings, A denotes a .horiz'oi'ital metallic han supported on the'top of a frame B in such mannera-s tob'e capable of being It has a steelyard or graduated. lever C suspended to it hy a stir.- rup c, as 'seen Vin vthe drawings, the 'fulcraof the said steelyard being seen ata o, Figs. l and 2. Directly above thesaid steelyard, and

a lever D, uihose:fulerun-journals are made tohang in a s tirrup d, suspended from the top bar of one side of. the frame l5, "lhesaid lever D carries on one arma sti rrup E, which is suspendedfrom it, -lreceives through its has a scale-pan F depending'` fromits lower end, as seen in the drawings. Apoise-weight G is screwed upon a screw 71, formed on: the other arm of the lever D, the said poise-weight being for the purpose of balancing'the weiggrht/f` of the scale-pan and its stirrup.

same side and on the long arm of the steek` yard is constructed so aste represent the whole cosi of -the article whatever be its A On cach side, y Of the steelyard-lever there is a 'scale made;`

weight,.providedthe cost of said -woi ght comes within the limits of the Scale.

Any article of which, either with orwithout aseertainingits weight, We desire to know the cost We place in the scalepan. This be ing done ,-We next lay hold of the slide-bar A, and. move the same longitudinally `until we bring thesteelyard into a convenient position to enable us to place the stirrup of the scale-pan directly on that division of. the short arm of the steelyard which denotes the price per pound or whatever may be the base or stainlard of `weight. Having previously placed or hung amovable Weight l onv the long arm ol' the steell)'"ard, vWe move the said Weight out on the saine .until we bring the steolyard into a horizonf talposition. That division o t the scale of the said long-arm on which the said wright may4 then be will denote the gross cost or whole 'cost of the article in the scale-pan, it being understood that the proportions of the scales' on the ,long and short arms have been previously properly regulated in such.ma-nner with' respect to the', balaneingaveight as to cause said weight to so indicate the wnole cosh' As the scales of `the steelyard are repre-v sented in 'Fig- 1, they enable a -person to as-A certain the whole costof an y article, prbvided lit does not exceed thesiunbf ;Iifty cents, for instance, and the price per vpound does not exceed-twelve cents, for instance. The short scale of thesteelyard 'is about one-half the length Ot thef long one.

divided into twelve parts, each of which is numbered `and subdivided into eight parts, ties'anie being as seen in the figure. The

The said short scale long scale is divided Vinto one' hundred equal fjparts, numbered as seen in l"the drawings. Nowgit the poise Pweighs two pounds, and .We place any article'in the scale the price of which per pound is six eents,for instance, We next movefthe steelyard into a properposition to enable ns to hang the scale or stirrup ber (i ot' the sca-le, denoting the price per pound. We next move the poise-weight P on the other scale ,until the steelyard becomes horizontal. lf the poise rests on the division indicatedby 'the number l0,(Wll1ich would be 4the sixtieth on 1he'sea-le,) .the price oi? the whole article'would be thirtycents. TheOpposite side of the steelyard is divided in such manner as to enable us to ascertain thewhole .thereof on the division indicated by the numprice of any articlewhen said 2 @nel price may be less than oneV dollar, and the price of it per pound is less than twenty-five cents. lr", however, We desire'to ascertain the Whole price of `an article Whose Weight would make the same exceed'one dollar and come between one and .two dol'la1"s,"wexnust apply a suitable Weight that is, such aone as would balance the steel- -Yard to the extent the Weight P would when placed attlie extreme end or 100 of the scale) on thesuspended platform l, hung at the end of the steelyard. This beingdone, We can employ the poise P to determine the excess of price aboye one-dollar;andbetween that and two dollars. l.

The scales and weights of the steelyard may be regulated in various other proportions and s -Ways to produce the above effect, 'as will loe' readily understood by balaneemakersl 'The above -described ,apparatus will be found especially useful to butchers, who by miean'sfof it will be able to readily discover the whole sutnfto be paid for anypiece of meat without 'rendering-"it necessary to rst` aseertain its Weight yin pounds and fractions of pounds. By hanging the scale-pan 'on the division lO of the short arm of the steelyard, Fig, 2, the poise and scale on the saine side of the other arm maybe used to obtain ihe Weight of any article.

VThe combination We claim and consideras our invention, consists as' follows:

First, the steelyard and scale-pan or any equivalent or equivalents therefor; second, the auxiliary ,scale on the short arm of the steelyard; third, the movable bar A or its equivalent; fourth, the balancing-lever vand stirrup of the scale-pan, the whole being made'-
