Specication forming part of Letters latent No. 195,45 i, dated September 25, 41877; application ledl March 2,1877..

To all whom it may concern Be it known that I, EDWARD KRONENBERG, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Counterfeit-00in Detecters, which improvement is fully set forth in the following specication and accompanying drawings, in which- Figure l' is a side elevation of the implement embodying my invention. Fig. 2 is a top view thereof. Figs. 3 and 4 are central longitudinal sections'thereot. Fig. 5 is an end view thereof.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of a case having in its top plate two slots, of the gage of the coin, and an inclosed single balance, so constructed that coins of different denominations may be weighed therebyfthe spurious pieces being detected by their inability to materially de press the balance and roll therefrom.

It also consists of a projecting arm for controlling the balance, so that spurious coin may be readily removed from the case.

lt also consists of guides depending from the top plate of the case below one or both of the slots thereof, whereby the spurious coin during the operation of removal will not catch under the top plate.

Referring to the drawings, A represents a case, consisting of sides A' A', top plate B, base C, open end D, and slotted end E.

In the top plate B there are two slots, vF F', which are of diiferent lengths, and adapted, say, for half and quarter dollars, and they extend end to end inthe longitudinal direction of the case.

Within the case, below the top plate B, there is mounted a balance, G, consisting of an elliptical-shaped or dishing bar, of such length as to project beneath both slots F F', and so weighted or hung that the weight of either a half or quarter dollar applied through the respective slot and rested on the bar will depress the balance.

It will be noticed that the portion a of the balance beneath the short slot F curves or extends slightly upward, and the portion b beneath the long slot F' curves downward, the

free end of the balance being at the open si e D of the case.

On the weightedV portion of the bala e there is an arm, H, which is secured ther o or formed therewith, and it projects throu h the slotted end E of the case, so as to be re ily handled. t

From the top plate B, and beneath t e walls of the slot F', there depend two ve ically-extending bars, J, which flare, the wid t part being below.

The operation is as follows: If a genui e half-dollar is placed through the slot F', or a genuine quarter-dollar through the slotF, it will rest circumferentially on the balance. a d it overcomes the latter, so as to cause it to scend and assume such position that the co n will roll therefrom and escape through t e open endD of the case, wherebyits genuinene s is established, after which the balance retur s to its normal position.

Should a spurious half-dollar be placed n the balance, the latter will not materially scend, and the depression or downward curv ture of the portion b of the balance preven s the spurious piece rolling therefrom, where y it projects sufciently above the top plate o indicate its nature. The same is true of a sp rions quarter-dollar, only that it will roll in o the portion b of the balance and project u ward through the slot ofthe larger piece, tl e result and indication of which being simil r to that stated of the larger piece.

.ln order to remove the spurious pieces t e arm H will be held so as to render the balan e immovable, whereby said pieces may be rea ilydgrasped by hand, or the arm will be raise whereby the balance descends and the piec s roll therefrom through the opening D of t case.

It will be noticed that the same balance employed for weighing coin of different d nominations, the operation depending up the introduction of the coin into the prop slot of the case.

As spurious pieces depress the balance to limited extent, and they are liable to catc under the top plate, the bars J are employe to prevent the same, their service being to d rect or guide the pieces into and tip throngf the slot F', whereby they are readily accessibleLl It is evident that the slots F act as gages beneath both slots', and having an upwardlyextending portion, a), and downwardly-extending portion b, substantially asand for the purpose set forth. v

2. The case and balance,r in combination with an arm, H, secured to the balance and projecting through the case, substantially as and for the purpose set forth. l,

3. The case with a slotted top plate and the balance, in combination with depending guiding-bars J, substantially as and for the purpose set forth.
