WATER VESSEL FOR KEEPING FRUIT AND VEGETABLES 



A novel water-containing vessel for preserving fruits and vege- 

 tables in a fresh state has recently been patented in tlic United 



States by an Argentin- 

 ian. The device con- 

 sists of a glass bobbin 

 containing water, fitted 

 %viith a rubber socket 

 iwhich fits closely over 

 the stem of the fruit and 

 prevents evaporation of 

 the water which pene- 

 trates into the stem of 

 the fruit as needed to 

 preserve its freshness. 

 This invention is partic- 

 ularly applicable to 

 choice bunches of grapes, 

 which can |be kept in 

 perfect condition for 

 many months by fitting 

 bobbins with rubber 

 sockets to both ends of the vineshoot. The grapes are then sus- 

 pended in a natural position and all the water in the bobbins is 

 maintained above the stem to be absorbed by the fruit as neces- 

 sarj'. — Luis Robichon, Mendoza, .\rgentina. United States Patent 

 No. 1.360,024.

A RUBBER-CUSHIONED HAMMER 



A new use for rubber is found in its application to a hammer 

 handle, thereby firmly holding the head to the handle without 

 wedges. A red rubber gasket is fitted over the handle and the 

 hammer head forced on over it. Its present use 

 is largely in rehandhng hammers and sledges, but 

 the inventor says that several hammer man- 

 ufacturers are considering placing it in their 

 manufactured product. Like the rubber tire, 

 the rubber gasket makes these hammers resilient 

 and tends to lessen shock to the user, thus con- 

 serving the workman's strength. He can use a 

 lighter hammer, also, and attain equal efficiency, 

 while he does not have to carry any "extra" 

 hammer to meet the emergency of the hammer head flying off. 

 The cushioned hammer, therefore, acts as a safety appliance, 

 preventing accidents to workmen, in addition to its other 

 advantages. — II. S. Isham, Belmar, New Jersey. 



A CORRUGATED INNER TUBE 



By a special patented process, the "XoCeem" inner tube is 

 made of red rubber in a mold which gives it an annular shape 



and corrugates that 

 portion of the exterior 

 surface which contacts 

 with the tire casing. 

 The compound used is 

 said to contain a 

 much higher percent- 

 age of actual rubber 

 than generally used 

 for inner tubes. The 

 size, in both milli- 

 meters and inches, is 

 molded on the surface 

 immediately at the 

 valve, for convenience, and the valve itself is seated on a specially 



reinforced fabric and rubber insert, properly and integrally 

 vulcanized. The corrugations prevent the tube from sticking to 

 the casing and its shape makes it practically impossible to exhaust 

 the interior air, tlicreby minimizing the tendency to stick together 

 or be pinched by the rim.— NoCeem Rubber Corporation, Har- 

 rison, New Jersey. 



"Wedge" Pencil Eraser 



PENCIL ERASER EASILY ATTACHED 



An invention which every pencil user will welcome is a prac- 

 tical rubber tip called the "Wedge" eraser, because of its pe- 

 culiar shape. When an attached 

 eraser is desirable it is readily 

 slipped on and will stay on. The 

 "Wedge" will erase large areas 

 readily without smudging. It 

 equals a "rubber finger" for 

 turning pages and keeps the pen- 

 cil from falling out of the 

 pocket. Its pyramidal sides keep 

 the pencil from rolling off the 

 desk and its weight and shape 

 keep the point upright if dropped. It is made of the best quality 

 soft red rubber and is claimed to outwear three pencils.— Joseph 

 Dixon Crucible Co., Jersey City, New Jersey. 



COMFORT IN TELEPHONING 



A pneumatic receiver pad is one of the new conveniences for 

 use with the telephone. It is made ring- 

 shaped of soft rubber to fit over the hard 

 rubber receiver, and encloses sufficient air to 

 permit the receiver to be pressed closely to 

 the ear, thus excluding all outside sounds and 

 aiding conversation in a noisy office.— The 

 Davol Rubber Co., Providence, Rhode Island.

"EVER.READY" FOLDING SHAVING BRUSH 



A novel convenience for travelers is a 

 sliaving brush that fits compactly into its handle, thus keeping 

 Jhc brush absolutely safe from contamination and also protecting 

 other contents of a traveling bag from contact with a wet brush. 

 The bristles are a mixture of best quality badger hair and are 

 vulcanized 

 in hard rub- 

 ber. This 

 wxll-known 

 feature of 

 high - grade 

 brushes 

 does away 

 with the an- 

 noyance of 

 loose bris- 

 tles, as once 

 set in the 

 rubber it is 

 impossible 

 for them to 

 come out, no 

 matter how 

 long the 

 brush is in 

 use. To use 

 the brush, 

 the hinged 

 cover is 



opened and closed again and the end of the brush fitted into the 

 opening. The handle is made with patented, reversible, self- 

 locking ferrule and when folded and packed ready for traveling
