Portable Fan Run by Motor<br />

A new form of fan for the household will prove welcome in<br />

places where electricity is not available, as it can be driven<br />

very cheaply by kerosene, gasoline, alcohol, or gas so as to set<br />

the air in motion as well as the best electric fans. This portable<br />

fan is so low-priced that it may be used where conditions<br />

do not justify the purchase of an electric fan. The lamp is in<br />

the lower part of the frame, where it is out of sight and protected<br />

from air currents.<br />

Grooves Hardwood Floors Quickly<br />

This interesting machine, used in the<br />

Chicago Postoffice, cuts a slot in<br />

floors sufficiently large to accommodate<br />

electric feed wires. This eliminates<br />

tearing up large expanses of valuable<br />

floor, as has been the practice in<br />

the past. A man operates the hand<br />

wheel, which feeds the cutter automatically<br />

as the groove is made, and at the<br />

same time keeps the pressure constant.
