Converting a Motor- Cycle Into a 

 Tricycle 



M O T O R 



A 



cycle may be 

 easily transformed 

 into a motor-tri- 

 cycle, by the use of 

 a patented axle 

 which is attached 

 by lugs to the low- 

 er end of the frame. 

 On the upper end 

 of the frame i s 

 bolted a spring, to which are at- 

 tached two uprights for the axle. By 

 this means the substitute axle is securely 

 fixed to the motor-cycle frame. A belt- 

 drive from the engine transmits the 

 power to the two rear wheels. 



Rough on the Hen — But Useful 



N order that the 

 poultry breeder 

 may identify the 

 hens which have a 

 propensity to enter 

 the nest to set need- 

 lessly, a valve Con- 

 taining ink or liquid 

 dye is placed at the 

 opening of the nest. 

 When a hen enters the box containing 

 the nest, a trap-floor drops, pulling a 

 string which opens the valve, thus 

 allowing some of the marking fluid to 

 fall on the hen's back.

To Keep Your Foot Always on the 

 Accelerator-Pedal 



O provide a 

 safe and com- 

 fortable rest for an 

 automobile driver's 

 foot so that he may 

 keep his foot in the 

 proper position 

 near the accelerat- 

 or-pedal, a rest has 

 been invented, 

 which consists of a tubular piece of 

 metal to be bolted to the floor at the 

 desired spot. On one side of the rest is 

 attached an upright piece of metal, 

 which acts as a guide to prevent the 

 foot from slipping in an emergency. 

 The rest fits directly under the arch of 

 the shoe. 



A 



A Single-Service Shaving Brush 

 SANITARY 



shaving brush 

 w h i c h m a y b e 

 thrown away after 

 having been used 

 once is made of a 

 pad of sponge or 

 antiseptic cotton 

 covered with a 

 flexible material 

 such as gauze or cheesecloth. This 

 brush is impregnated with a sufficient 

 quantity of powdered soap to lather the 

 face. The brush is adapted to be made 

 in large quantities at a very low cost, so 

 that it may be thrown away after every 

 shave.

Adjusting the Big Shoe-Stand to 

 the Little Boy 

 O enable small 



^ 



children to 

 have their shoes 

 polished without 

 difficulty, an in- 

 ventor has made a 

 pair of substitute 

 foot rests for a 

 polishing stand. 

 These rests may be 

 easily attached to the stand, and are so 

 designed that they will accommodate 

 any size of child's shoe. A pair of heel 

 and toe clamps are attached to the shoe 

 plate and are connected by means of a 

 coiled spring. 



Finger-Holds for Your Slippery 

 Bath-Tub 



SOME difficulty 

 is often exper- 

 ienced, especially 

 by invalids, aged 

 people and chil- 

 dren, in seating 

 themselves in the 

 modern enamel or 

 porcelain bath tubs. 

 The surfaces are 

 naturally slippery, and this difficulty is 

 mcreased by the presence of water and 

 soap. An inventor who must have 

 slii)ped has provided gripping surfaces 

 under the rolled edges of the tub, so that 

 the bather may easily change his 

 position.
