Abstract

10,821. Iles, C. E. May 19. Thimbles.-For the purpose of ventilating the interior of thimbles, the crowns are provided with one or more holes and a perforated guard is provided in the interior of the crown. In the form shown in Fig. 1, the crown a' has a central hole a<2> and a guard b of steel wire-gauze is fitted immediately below in the form of a shallow cup. Below the guard is a hexagonal disk c, while below the disk is another gauze disk d superimposed upon a perforated diaphragm e. In a modification, the gauze is dispensed with and a star-shaped disk used, and in another, only a gauze disk is used above the perforated diaphragm. Where the thimble has a lining f, the parts are held up between the lining and the crown, but where there is no lining, the disk c and any other elements used, may be secured in an annular groove a<3> formed in the interior of the thimble, as shown in Fig. 9, or the walls may be indented beneath the disk. In a further modification, shown in Fig. 11, a well a' is made in the crown a', and the sides of the well are perforated to provide ventilation holes.
