Abstract

23,937. Mathews, C. L. Oct. 19. Pokers.- Relates to devices for splitting coal, &c., comprising a splitting- point and a striking- member slidably mounted within a tube, which may serve as a domestic poker The enlarged head d of the splitting - point c is packed rouod with suitable fibre d<1> so that it slides with some degree of friction within the tube a in order to prevent splintering of the coal or the like by the rebound of the point. In the form shown in Fig. 2, the striking-plunger e is screwed into an outer tube b provided with a weighted head b<1> and is guided longitudinally by a pin f and a slot g. In the form shown in Fig. 5, the head d of the needle c and the end of the plunger e are shaped to overlap. The plunger is brought into operative position by giving it a pull and half-turn, and is controlled during this movement and its subsequent reciprocation by the pin l and slots m, m<1>, m<2>.
