An Adjustable Auto Foot-Pedal 

 for Short-Legged Drivers 



SHORT per- 

 sons usually 

 have difficulty in 

 driving an auto- 

 mobile because of 

 the distance of 

 control pedals 

 from the seat. 

 Especially is this 

 the case in cars made in large quan- 

 tity, where no allowances are made 

 for the varying leg lengths of prospective 

 owners and drivers. For the convenience 

 of these short-legged persons there has 

 been brought out the two-step extension 

 pedal, which can be attached and adjust- 

 ed in a few minutes. The pedal consists 

 of two sections with a serrated joint, sim- 

 ilar to that of the adjustable handlebars 

 on bicycles. The pedal can be adjusted 

 to suit any driver and is nickel plated. 



An Extra Seat for Ford Cars Which 

 Hangs on the Door 



ROWDING 



one or two 

 extra persons in- 

 to a Ford car ap- 

 pears to be rather 

 more of a habit 

 than before. Time 

 has shown that a 

 little Ford tour- 

 ing car can be relied on to "ramble 

 right along" with as many as seven 

 people in it, and inventive geniuses 

 are busy supplying additional seats. 

 The accompanying illustration shows 

 a neat, simple and very light seat, 

 to be hung over the doors of the car. 

 The hinges at the bottom of the hanging 

 rods show that the seat can be folded 

 flat. The device is finished in japan, 

 with padded leather or pantasote seat. 

 The hooks are also padded with leather 

 to avoid marring the finish of the doors. 



Beeswax for Cracks and Holes 



WHEN filling cracks and holes use 

 beeswax instead of putty. Heat 

 it until it is plastic and push it into the 

 crack. Then sandpaper the wood around 

 the crack and let the dust mix with the 

 beeswax. \\'hen the wood is stained, 

 the crack will be hardly noticeable. 



This Folding Motor Bucket Is Also 

 a Game Bag 



WATER 



A 



bucket which 

 folds up and may 

 be put in the door 

 pocket or under the 

 cushions of an au- 

 tomobile is one of 

 the most convenient 

 of recent motor ac- 

 cessories. It is made 

 of heavy brown wa- 

 terproof canvas and 

 holds over a gallon. 

 The only metal in 

 the bucket is the top 

 rim, which folds compactly, and 

 when unfolded stays in position. To un- 

 fold, the rims are pushed out I'j the reg- 

 ular size and the bucket is immediately 

 ready for use. It may also be used as 

 a fish or game bag, by leaving it flat and 

 fastening a strap or small rope in the 

 loops on the side of the bucket. This 

 latter fact makes it especially handy for 

 a long tour. 



A Machine for Cleaning Blackboard 

 Erasers 



A MECHAN- 

 ICAL clean- 

 er for blackboard 

 erasers has been 

 brought out 

 which will entire- 

 ly obviate the 

 highly unpopular 

 schoolroom task 

 of beating the 

 erasers on the 

 window sills, with 

 the unpleasant 

 clouding of the 

 room which ac- 

 companies this 

 operation. The apparatus consists of 

 several pivoted handles with erasers fas- 

 tened at the upper ends, an upright 

 screen and a rotating shaft fitted with 

 cams. Rotated by a handle at the end 

 of the machine, the cams force the han- 

 dles outward so that they descend brisk- 

 ly upon the screen, thus driving out the 

 chalk dust retained in the erasers. A fan 

 whirling rapidly at one end of the screen 

 blows the dust away from the operator.
