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.
