Why Not Dress Alike and Save 

 Money During War Time? 



WHY not a civilian uniform as a 

 measure of economy in clothing? 

 suggests a Canton, Ohio, man. It could be 

 worn by everyone, man, woman and child, 

 and thus eliminate foolish dressing, the 

 dude, and the spending of hundreds of 

 thousands of dollars on needless finery. It 

 would certainly bring home to the civilian 

 population their part in the war, and the 

 ladies would need to apologize no longer for 

 appearing twice in the same dress. As the 

 result of investigation carried on by the 

 Ohio man, a standardized suit of wool of 

 excellent quality could be sold for less than 

 twenty dollars. 



The inflow of compressed air is controlled by a

With the Warm Weather Come Im- 

 provements in Ice-Cream Making 



THE ice-cream manufacturer encounters 

 the same difficulty in removing blocks 

 or forms of cream from their molds as does 

 the average cook or housewife with her 

 frozen desserts. 



A recent device, patented by 

 L. M. Hendler, of Baltimore 

 Md., for overcoming this 

 difficulty, is a contri- 

 vance for forcing 

 warmed air through a 

 pipe to the bottom of 

 the mold to dislodge 

 the bricks of cream. 

 This is more par- 

 ticularly for the 

 convenience of 

 dealers who handle 

 large oblong blocks 

 of cream which 

 must afterward be 

 cut up into the 

 smaller bricks. The 

 valve which controls 

 the compressed air in- 

 flow is conveniently op- 

 erated by a foot-lever.

A New Type of Transmission 

 Employs Cork Inserts 



THE new type of transmission band 

 shown in the accompanying illustra- 

 tion is designed to overcome the objection 

 to the planetary form of transmission, such 

 as used on the Ford car. It has cork in- 

 serts like buttons. These extend out 

 beyond the band proper for a very slight 

 distance and come into direct contact with 

 the revolving drums as the speed is changed. 

 On account of the high coefficient of 

 friction of cork and steel, the braking 

 effect commences at once, whereas the 

 plane surface fabric band usually fitted 

 slips as it becomes worn and glossy and does 

 not grip except when an excessive amount 

 of pressure is exerted on the transmission 

 pedal. Then it grips suddenly, 

 causing a jarring in the 

 operation. 



The cork buttons 

 also act as springs; 

 ^ for as the pressure 

 increases they are 

 compressed, thus 

 allowing the band 

 itself to come into 

 contact with the 

 'drum. This 

 makes an easily 

 operated trans- 

 mission which acts 

 positively without 

 slipping, even after long 

 service, and one in 

 which the bands have a 

 longer life due to this 

 practical elimination of 

 rhe slipping.
