THE INDIA RUBBER WORLD 



[September 1, 1914. 



New Rubber Goods in the Market. 



A PNEUMATIC PEN FOR PLASTICS. 



AN iiistrunient has bct-n recently iiivc-nteil lur writing, mark- 

 ing or decorating with plastic materials. I'he iien barrel is 

 hollow, and connected to the rubber bulb in which the 

 liquid plastic is placed. In operating the device the writer takes 

 the pen in one hand and presses the air bulb with the cither. 



This forces the air through the rubber tuljc, compressing the 

 plastic material which flows out at the pen point. A fine or 

 coarse line can be drawn by varying the speed movement of 

 the pen or by pressure on the air bulb. The latter is provided 

 with a check valve. This device can also be used for applying 

 the fancy decorations on wedding or birthday cakes. Patent No. 

 1,099,344. 



RUBBER IN EGG TESXraG. 



The egg testing device il- 

 lustrated herewith comprises 

 a tube of rubber, tapered at 

 one end and with beaded 

 edges. The larger end of the 

 tube is placed over the lens 

 of a portable electric lamp, 

 and the other is applied to 

 the egg to be tested, as shown. British Patent No. 6,183 (1913). 



THE CASTLE DANCING PUMP. 

 This new dancing shoe has been designed to meet the require- 

 ments of lady tango enthusiasts. A band of elastic fabric ex- 

 tends ever the instep, holding the shoe in place. A leather strap 



and buckle con- 

 ceal the elastic 

 f a 1) r i c . This 

 strap is pro- 

 vided with a 

 fastening device 

 at one end 

 which can be 

 unclasped when 

 it is desired to 

 remove the 

 shoe. 



THE 

 •SANITOR." 



One of the 

 latest sanitary 

 inventions and 

 aids to health 

 is the "Sanitor," a device for cleansing the mouth by vacuum 

 drainage and for massaging the gums, thereby stimulating 

 a full flow of blood to the tissues — effects considered ex- 

 ceedingly beneficial in Pyorrhea. The invention consists of a 

 rubber mouth cup which fits over the teeth and gums of either 

 jaw, connected by means of a rubber tube with a motor operated 

 pump. In the dental office this device is used also for draining 

 Aviolar abscesses. [The Sanitor Co., Chicago.] 



THE PHO-NO-GEHM. 



The iiart th.-it rubber plays in the "Pho-No-Gcrni." or tele- 

 phone disinfector, will be seen by reference to the accompanying 

 cut, which shows the disinfector attached to the telephone trans- 

 m i t t e r . The 

 c o n t a i n e r is 

 filled t w o - 

 thirds full with 

 a n anti.septic 

 solution, whicli 

 under labora- 

 tory tests has 

 been found to 

 kill such dead- 

 ly germs as 

 s t a phylococci, 

 s t r e ptococci, 

 diphtheria and 

 typhoid, any or 

 all of w h i e h 

 might be dis- 

 tributed by the 

 medium of the 

 telephone. A 



few pressures of the ruliber vacuum-bulb of this antiseptic liquid- 

 containing disinfector, however, is sufficient to clear the line.

RUBBER PLUMMETS TOR JUMP STANDS. 



The cords on the jump stands which form a part of field 

 sports apparatus are now provided at their ends with rubber 

 plummets, so that should a contestant fail in his attempt to clear 

 the cord and instead become entangled in it, he may sustain no 

 serious injury through contact with the weights used to hold 

 the cord in place. 



A PIECE OF RUBBER ERASER FOR A REEL-SEAT. 



A fisherman with an ingenious turn of mind has discovered 

 that the use of a small piece of rubber keeps the reel-seat of his 

 rod taut and firm and makes a highly satisfactory arrangement. 

 He bought an ordinary eraser, cut off a section about half an 



inch long, cut out a little of the rod in the center of the reel- 

 seat and inserted the piece of rubber. When the reel is pressed 

 down in place on this piece of eraser and fastened in the usual 

 way it cannot come loose. This is not, perhaps, an important 

 new use of rubber, but one that wHl be interesting to fishermen. 



THE DIME SCREEN DOOR CHECK. 



.\ bumper has been devised to prevent the annoyance of slam- 

 ming screen doors. It is made of molded rubber, tapered to give 

 the greatest amount of spring, and is attached to the door frame. 

 It is operated in connection with a plunger on the door and is 

 said to be most effective, giving equal satisfaction whether the 

 door is opened wide or only partly opened, as it does not de- 

 pend upon the momentuin of the door to make it work. As its 

 name suggests, the price of this check is only ten cents. [The 

 Caldwell Manufacturing Co., Rochester, New York.]
