��Straw Hat Insurance O longer need we fear the elements when we essay forth in our new straw hats. Come dust or rain — our pro- tection is ample. The invention that calls forth this outburst of enthusiasm is a light hatshield, printed in imita- tion of the kind of hat it covers — supported by an ingen ious
frame and fastened in place by tension
clips. That it may always be at hand
in case of need, it is kept
folded inside the crown.

��Fooling the Pickpocket
NO one can open the bag shown in the illustra- tion without being detected, whether it is being carried or not. A small battery 2 is connected with a bell 3, which is connected with a metal plate 4, located near, but not touching another plate 5. Connected with plate 5 is one of two bars, placed the one above and below the handle of the bag. The other bar is con- nected with the battery, a small switch being in- serted between them for breaking the circuit when desired. Situated close to the two plates 4 and 5 and actuated by one of the hinged mouth- bars of the satchel is a switch or con- tact-bar 8. When the bag is opened, this bar touches both plates and thus completes the circuit, ringing the bell, and warning the owner.
���A Buzz- Saw Safety Razor
RAZORS have been further improved by means of a device for rotating a safety blade. A small motor 3 isencased with- in an insula- ted handle. Small gear- wheels, 6 and 7, transfer the |)ower to a re- volving shaft 5, to which is attached a razor- blade 4. The electric current
is carried to the motor by means of a cord I, which passes through the handle, as shown in the diagram. The lever 2 serves for turn- ing on the current. In operation the blade moves ( I(we to the opening 8.

���A Tray to Hide Unsightly Cigar Ashes N ash-tray which elimi- nates the unsightly appearance of cigarette stubs and the fumes they give off, is shown in the illustration. A funnel-shaped part has its lower opening attached to the upper rim of a cylindrical box. Resting in the funnel is another member, consist- ing of two cones with their bases together. At their widest part, they rest on the funnel at its junction with the box. A ring- shaped trough is thus formed, into which ashes may be deposited. The cone is supported by a vertical pin attached to the base of the box. By lifting the cone, the ashes fall in the box. The ill-smelling fumes, however, are prevented from escaping.
