UNITED STATES PATENT QFEIGEi WILLIAM H. RICE, on NEW YORK, N. Y.
IMPROVEMENT IN COUN TERFElT-COIN DETECTERS.
Specification forming part of Letters Patent No. 196,168, dated October 16, 1877 application filed April 23, 1877.
To all whom it may concern:
Be it knoim that I, WILLIAM H. RICE, of the city, county, and State of New York, have invented a new and Improved Coin-Tester, of which the following is a specification:
In the accompanying drawing, Figure 1 represents a top view; Fig. 2, a vertical transverse section on line w 00, Fig. 1; Fig. 3, a vertical longitudinal section on line y y, Fig. 2, of my improved coin tester as adapted for pocket use; and Figs. 4 and 5 are a top new and vertical transverse section of the same on line 2 .2, Fig. 4, shown as applied to a moneydrawer, coimter, 8:0.
Similar letters of reference indicate corre sponding parts.
This coin-tester is intended to form a convenient, compact, and reliable device for pocket use, or for cash-tills, 850., by which the coins are exposed at one and the same time to thedouble test of. weight and measurement, so as to detect at an instant the counterfeit pieces without attracting any attention to the testing of the same.
The invention consists of a coin-tester having one or more guide -tubes gaged in length and width for coins of different denominations, in connection with a fulerumed and weighted trap-lever gaged to the weight of the genuine coins.
In the drawing, A A represent the tubes for the coins, of which one or more may be arranged above a fulcrumed and weighted triplever, B, that extends across the bottom opening of the tubes.
The tubes A are gaged in length and width to the size of the special coins to be tested, and the weight of the trip-lever gaged to the weights of the coins, the tubes for the smaller coins being in front of the tube for the larg r coin, so that the increased leverage compel sates for the less weight of the smaller coin The weighted trip-lever is inclosed in a casiir C, so as to be protected and not exposed injury after being once adjusted. The test is thereby capable of being carried in tl pocket or attached by side flanges to a mone drawer, counter, or other receptacle. Tl coin to be tested is inserted into the prop tube, and then dropped, the genuine and ful weighted coin passing in without difficult and tripping instantly the weighted trip -leve while the spurious coin, being either too lar is prevented from passing through the tube. or, when the same is capable of passing into th tube, it is too light to trip the trip-lever, 01 account of the less specific gravity of the basr alloys forming thus a twofold test that d tects with absolute certainty the counterfe I coins. The test may be used without a tracting attention and giving offense to th parties offering the coins, which is of special advantage and less objectionable for use in the trades. Having thus described my invention, I claim as new and desire to secure by Letters Patent- A coin-tester consisting of a series of conktubes in whichrests one arm of alever weighte on the other, the coin of different denominations resting upon said arm at different distances from the fulcrum of lever, according to their respective weights, as shovn and described. 5 WILLIAM H. RICE. Vitnesses E PAUL GoEPEL, O. SEDGWICK.
