SPINDLE FOR TIME-PIECE DIALS.

SPECIFICATION forming part of Letters Patent No. 486,973, dated September 23, 1890.

Application filed October 19, 1887.

To all whom it may concern.-

Be it known that I, MARTIN v.13. ETHRIDGE,

a citizen of the United States, residing at Boston, in the county of Sn ftolk and State of Massachusetts, have invented certain newand useful Improvements in Spindles for Time-Piece Dials; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to an iinproveinentin spindles for use in time-piece dials, such as are shown and described in my former patent, No. 319,804, dated June 9, 1885; and the invention consists in the construction and combination of parts, substantially as will be hereinafter described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a perspective view of my improved spindle for use in time-piece dials. Fig. 2 is a perspective view of the numeral block or shell. Fig. 3 is a mold for fashioning the numeral-block shells.

Like letters denote like parts.

In carrying my invention into practical effect I first provide hollow shells A, of a rectangular or other convenient form, on whose faces figures maybe marked in any desirable way. These shells may bemade of any suitable material, such as metal or some composition. When made of composition they may be formed,if desired,in a mold similar to that shown in Fig. 3, it being desirable that the mold shall be of a shape to impart to the shell a hollow rectangular form, provided the block is to be of a rectangular shape, or to impart to it any other form that is desired. Itis desirable, also, that the mold shall impart depressions to the outer faces of the shell, which depressions shall be outlined like the figures to be marked on said sides and adapted to be Serial No. 252,826. (No model.)

filled with material of a diiierent color from the shell, so that the figures may be prominent.

B denotes the rod, of suitable length and size and made of metal, wood, or other material. The shell A is attached to this rod.

In attaching the numeral-blocks to the rods I locate the rods centrally through the shell, properly distancing the latter from the end of the rod, and then around the rod inside of the shell I fill a cheap plastic adhesive substance O, which will harden in the shell and firmly bind the shell and rod together. This material C may be of any plastic sort, provided it has adhesive qualities sutficient to make it a strong binder for the rod and shell.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The herein-described spindle for time piece dials, consisting in the combination of a rod, the hollow shell having the numerals marked on the faces thereof, and a plastic filling for the interior of the shell, whereby the shell and rod are firmly bound together, substantially as described.

2. The herein-descrilmd spindle for timepiece dials, consisting in the combination of the rod, the hollow shell having numeralshaped depressions in the exterior surface thereof filled with a differently-colored substance from the shell, and the plastic filling within the hollow shell, whereby the shell and rod are firmly connected together, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
