For an improvement in Bell Hanging; James Russell, New York, October 10.
The particular arrangement of the parts of this apparatus cannot be explained without a drawing. The object proposed is to save room, and make one bell answer for a number of apartments. A box, or case, is fixed in the room containing the bell; within this box there are a number of sliding bars corresponding with the number of apartments from which bell wires are to extend. There are also in this box a number of plates of metal, equal to the number of sliding bars, or of wires; these plates are so constructed, that when a wire is pulled, one of the plates of metal tilts, by the action of its corresponding bar, and a disk, attached to it, having the number of the room on it, projects through a groove formed in a brass plate at one end of the box, and thus indicates the apartment where the servant is wanted. Each of the bars is made to act upon the same bell, and when a second wire is pulled, it replaces the index of the former, as its own is displayed.
The contrivance is ingenious, and will evidently answer the purpose intended; it is particularly calculated for large establishments.
