��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 foot-treadle so that the hands are free to move the block to and fro under the pipe mouth
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.
