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.
