��A Convenient Milk and Butter Slide for Refrigerators
OF all the foods kept in a refrigerator milk and butter require the most frequent opening of the food compart- ment. They arc removed for each meal, returned after the meal, and arc taken out between meals for use in cooking. When they share the usual large chamber the entire compartment is opened to the warm air each time. A new refrigerator accessory is a milk and butter slide arranged separate. It reminds one of a drawer in an office filing cabinet.
Upon opening the small door a metal skeleton slide appears, so divided, that it holds two one-quart milk-bottles and three one-pound bricks of butter, each bar of butter resting on a removable sanitary tray which can be carried to the table. Only one-tenth as much cold air is lost as when the door to the main provision chamber is opened. The metal slide is plated with zinc, and nickel.
Not only does this arrangement pre- vent the rapid melting of the ice, but there is another advantage. Butter and milk absorb odors and vapors given ofif by other substances. This difficulty is obviated by means of this device and the odor of onions, meat, etc., does not reach the butter and milk.
����The disagreea- ble task of han- dling ice is great- ly lightened by the use of a simple ice -grip which can be used for lifting, shaving, or split- ting. It consists simply of a roughened piece of metal provid- ed with a strap to fit the hand
��An Ice-Grip With Many Uses
THE slippery, cold block of ice delivered by the iceman can be grasped safely by holding it with a pair of ice-grips. Each grip has an oval, roughened face to make contact with the block. On the back of each is a strap for the hand. For its second use a grip becomes an ice-pick. At one end is a sharp point for this purpose. When shaved ice is wanted a grip becomes an ice shaver.
��Butter and milk should be kept separate from the other foods in the refrigerator
��Another Way to Rejuvenate Eggs
A MARYLAND man has found a means of preserving eggs with a substance known as "liquid petrolatum," which he claims will rapidK' penetrate eggs, when applied e.\ternall>', and make them proof against moisture or bacteria. The preserving substance is a mi.xture of hydro-carbons. When properh' treated, eggs can be preser\ed under a normal temperature for many weeks without deteriorating.
