An Electric-Lighted Watch Base like the one shown in Fig. 90 makes an attractive little clock for chiffonier or dresser. It was designed to hold a watch from bed-time till get-up-time. A small electric-lamp, operated by a dry-battery, and controlled from the bed by a push-botton
Fig. 94. - Back for Necktie or Towel-Rack Shown in Fig. 89 illuminates the watch-face. With the addition of a calendar mounted beneath the electric-lamp socket, this little sentinel stands in constant readiness to give information as to the time of the day, and the day of the week and the month.
Working-drawings of the parts of the battery-case are shown in Figs. 95 and 96, and Fig. 97 shows how the parts are assembled. Front piece A (Fig. 95; is grooved near the side edges to receive the edges of side pieces B. If you haven't an expansive-bit with which to cut the watch-face opening, bore several small holes, split out the wood between
Fig. 95. - Front A, Sides B, and Back C, D of Electric-Lighted Watch
Base Shown in Fig. 90 the holes, and trim up to the circumference of the 1 3/4-inch opening with a chisel. Side pieces B are grooved near the rear edge to receive the sliding-back C. The edges of sliding-back C are rabbeted as shown in the cross-section of
Fig. 95, to slide in the grooves in sides B. Strip D, nailed to the top of sliding-back C (Fig. 97), forms a lift for raising the sliding-back. Strip D and piece E form the top to the case. Dimensions for top piece E are given in Fig. 96, as are also dimensions for base block F. Base F is grooved to receive the lower ends of front A and sides B. The
Fig. 96. - Top E, Base F, Watch Support G, and Spring Attachment H, I, U, of Electric-Lighted Watch Base Shown in Fig. 90 cross-section drawing in Fig. 96 shows the size of the grooves. Cut all grooves with a small chisel.
Block G (Figs. 96 and 97) forms the bottom of the watch pocket. Fasten it below the opening in the watch front, as shown in Fig. 97. The back of the watch-pocket is a circular piece of wood (H, Fig. 96). In order to keep the
Fig. 97. - Detail Showing How Watch Base is Assembled; also Battery, Lamp, Push-Button, Cord, and Connections of Same watch close to the front of the case, there must be a spring back of it. Use a piece of the main-spring of an old alarm-clock ( U, Figs. 96 and 97). Fasten one end of the spring to the back of block H, the other end to a strip I. Fasten strip I to the inside of front piece A (Fig. 97), at the right height to bring disk H directly back of the watch opening.
Having grooved and rabbeted the parts as shown, it is not much of a trick to assemble the battery-case. Glue alone will suffice to hold grooved joints, but a brad or two in addition will not go amiss. Drive in the brads carefully, and drive their heads slightly beneath the surface of the wood so they can be concealed later with putty.
After you have completed the case, it is well to put the finish on the wood before installing the lamp, battery, etc. When the finish has been applied, glue a piece of light-weight felt, or heavy cloth, to the under side of the base, as a protection to surfaces on which the watch-base will stand.
The Electric-Light Attachment requires a miniature brass wall-plate (J, Fig. 97), a brass right-angle nipple (K), a miniature lamp-socket (L, M, N), a 1 1/2-volt mazda lamp (0), a dry-battery cell (P), 3 yards of flexible silk-covered double-conductor lamp-cord (Q and R), and a pear-shaped pushbutton (5, T). The manner in which the connections are made is shown in Fig. 97. Two small holes must be bored through the front of the battery -case, as shown, the upper hole for the wires connected with the lamp to run through, the lower hole for the wires leading from lamp and battery to push-button, to run through.
If your battery dry-cell fits too snugly in its case, hollow out the inside face of the sliding-back C a trifle, as indicated by dotted lines in Fig. 95.
