Starting the Kerosene Car from the 

 Kitchen Range 



ONE of the most unusual 

 devices yet invented 

 for heating kerosene fuel 

 when an automobile us- 

 ing such fuel is to be 

 started, consists of a 

 rectangular metal 

 block with holes 

 punched through it. 

 This is heated by- 

 being placed for a 

 few minutes over the 

 kitchen gas range, or 

 coal stove, and then 

 inserted in a similar 

 sized rectangular box, 

 placed in the intake man- 

 ifold, between the carbur- 

 etor and the cylinders. 

 When starting the car, the 

 kerosene fuel is heated on 

 its way to the cylinders, 

 so that it vaporizes quick- 

 ly. The block is not re- 

 moved until again 

 quired.

The Aerautoniotricycle — a Weird 

 Machine Made by a Doctor 



FOR a cool spin on a hot afternoon, the 

 vehicle shown herewith has con- 

 spicuous merits. The propeller in front 



Tricycle with engine-and-propeller mechanism built by an 

 enterprising and ingenious phjsician of New York City 



secures an effective and bracing air bath 

 for the driver. 



Mechanically, this vehicle demonstrates 

 that the three well known ele- 

 ments, a tricycle, an air- 

 cooled "V" motorcycle 

 engine and a propeller 

 can be combined, 

 and how showy 

 the combination can 

 be made. The gaso- 

 line tank at the top, 

 with its pointed ends 

 to pierce the atmos- 

 phere, suggests great 

 speed. If the propeller 

 were at the rear, close 

 to the engine, the ma- 

 chine would look com- 

 mon, as there would then 

 be no need of the long 

 overhead frame of tubes 

 or the complicated steer- 

 ing, and much vibration 

 of the propeller shaft 

 would be suppressed and 

 escape notice. Actually, 

 the propeller blades are 

 made of thin sheet metal 

 for lightness, and there- 

 fore have to be braced with guy wires. 

 This type of blade — the same as that used 

 for the cooling fans of automobiles — con- 

 sumes much more power than it returns 

 in propulsion. By virtue of this property, 

 which under other circumstances 

 might be termed a defect, it 

 tends to keep the engine 

 busy and quiet even at the 

 very moderate speeds for 

 which the vehicle seems best 

 suited. There are no springs 

 or other means for moderat- 

 ing road shocks and vibra- 

 tion of the whole structure. 

 As it appears in the photo- 

 graph the machine is harm- 

 less, the chain being removed 

 from the large sprocket wheel 

 on the drive shaft, but it 

 gives an excellent idea of its 

 appearance as it runs around 

 the city streets and avenues. 

 The machine has given its 

 owner much pleasure and 

 amusement, both in its 

 building and running.
