Good as are the many devices which have been invented, patented, or proposed, for the purpose of attaching and connecting the ends of belts, we are not aware of any that can surpass for cheapness and perfection the one which is the subject of our engraving. Its simplicity can be at once appreciated by reference to the illustration. A, Fig. 2, is the coupling ; it is of cast iron, and consists of a central bar, provided with arms, a, whose ends are bent inwards, so that they will hold or " bite" into anything in which they may be placed. Fig. 1 shows the application. C is the periphery of a band wheel, and B B are the ends of a belt, that have holes punched in them just corresponding with the arms, a., of the coupling, which are placed in the holes as shown, and the moment the slightest strain comes upon the belt, the coupling "bites," and the belt is firmly and securely joined. The coupling is flush with the inside of the belt, and so does not obstruct, in the slightest, its motion. We have seen certificates from persons who have had these couplings in use some time, and all say that they answer admirably. This improvement was invented by Lewis Smith, of Buffalo, N. Y., and patented by him Nov. 17, 1857. Any further information can be obtained by addressing B. W. Miller, Buffalo, N. Y.
