It Ought to be Light 



,N aliinii- 

 luini hil- 

 liard-ciic has 

 been devised 

 by a Nebras- 

 ka man who 

 has long 

 searched for 

 a Hght cue. 

 His cue is 

 made of akiminum and has a rectangular 

 metal twisted and embedded in the 

 aluniinum. It is strengthened by ferrules 

 extending around it which serve to 

 ornament it. The cue is hollow for a 

 portion of its length and is pro\ided 

 with a means for securing the lip rigidly 

 to the striking end.

swatter de- 

 signetl for use in 

 killing flies, mos- 

 (luitoes and otiier 

 insectson the ceil- 

 ing of a room or 

 on the walls con- 

 sists of a spring in 

 a rod which forces 

 the swatter end of the instrument against 

 the insect with sufficient force to kill it. 

 When the knob at the end of the rod 

 is released by the operator the swatter 

 end strikes the wall quickh'. The rod 

 is kept in a set position by locking the 

 spring in place. The swatter end may 

 be fastened to the handle with a cord.

Beating the Dentist to It 

 TOOTH- 



cleaning in- 

 strument invent- 

 ed by a Kansas 

 City man has a 

 strand threaded 

 and spanning a 

 portion of the in- 

 strument for in- 

 sertion between 

 the teeth to re- 

 move foreign matter. The principal 

 object is to provide a sanitary dc\ice 

 with a means for holding the strand in 

 proper tension and removing a ])ortion of 

 it after it has been used and substituting

Facilitating Speed in Writing 



N attach- 

 ment for the 

 hand has been in- 

 \- e n t e d w h i c h 

 makes fast writ- 

 ing possible. It 

 is a movable rest 

 for the hand 

 which while facil- 

 itating the ac- 

 quirement of 

 speedy writing secures the steadying ef- 

 fect usually imparted b>- resting one or 

 more fingers on the ]ia]5cr,but without re- 

 tardation resulting from the latter prac- 

 tice. Frictional contact of the hand 

 is thus obviated and speed increased. 



A 



\ 



A Cure for Butter Fingers 



instrument has been in\ented for 

 music learners and all others (e.x- 

 cept the pickpocket) whose fingers are 

 stiff and won't behave. It is a finger- 

 spreading device which allows the fin';ers 

 to be lifted, depressed and exercised in 

 a dozen different ways beneficial to the 

 person learning intricate movements (jf 

 violin and piano 

 playing. The two 

 blocks of wood are 

 fastened to a 

 w o o d base by 

 screws which may 

 be tightened or 

 loosened at will. 



Automobiling with a Bicycle 



THF, bicyclist can imagine he's auto- 

 mobiling with a new device which 

 dispenses with the ordinary handlebars 

 and substitutes in lieu thereof a steering 

 wheel which enables th'j rider to assume 

 an upright and comfortable position 

 and thus obviate 

 incident to 



mjurN 

 bending down. 

 The dex'ice can be 

 quickly applied 

 to the frame of any 

 ordinary bicycle 

 or motor-cycle to 

 fit riders of var\'- 

 ing proportions.
