The old Dutch wooden shoe as an adver- 

 tising device on wheels 



A Quaint Advertising Automobile 



DESIGNED to resemble a wooden 

 shoe, such as the peasants of Hol- 

 land wear, the automobile pictured is 

 curious enough. The lines of the sabot 

 are correctly followed, and even the ap- 

 pearance of wood is secured by artistic 

 graining. It is a most attention-com- 

 pelling bit of advertising on wheels. 



Gravity-Flow Gasoline Supply Station 



THE owner of an automobile gaso- 

 line supply station installed a tank 

 with a glass gage. The tank is much 

 above the fuel tank of any automobile, 

 so that the gasoline flows by gravity, the 

 quantity being controlled by the pur- 

 chaser at his machine. The tank has 



been accurately calibrated and checked 

 by an official. This insures no shortage 

 from leaky valves. This apparatus is less 

 expensive and easier to operate than an 

 ordinar\- pump. 



A Portable Wrecking-Truck 



A SMALL light-weight wrecking- 

 truck, which can be carried with 

 ease in a relief car, has been designed 

 by a Danville (111.) man, and has been 

 useful in his business. When called 

 from his garage to tow in a WTecked car 

 with a smashed wheel, he does not have 



Why not let gasoline run down into 



your fuel-tank instead of pumping it up 



by armpower? 



Is it not better to tow a wrecked 



automobile in this way than with the usual 



awkward timber drag? 



to drag in the wreck on a four-by-four 

 timber, set under the axle of the missing 

 wheel, but slips the truck in place instead 

 and tows the car home without difficulty. 

 It fits under the front or rear axles with 

 a few minutes' work, and the caster-like 

 arrangement of the wheels makes it easy 

 to steer. 



An Oil-Proof Cement 



A CEMENT which will not be af- 

 fected by oil is made by mixing 

 glvcerine and litharge to the consistency 

 of a thick paste. This will be found very 

 handv in repairing cracked oil-reservoirs 

 or in making an oil-tight joint between 

 two metal plates. The cement should be 

 applied as soon as it is mixed, since it 

 hardens very quickly.
