NEW GOODS AND SPECIALTIES IN RUBBER. 



DUPONT'S NEW PNEUMATIC TIRE. 



AVERY ingenious and simple invention in the line of 

 pneumatic tires is that shown in the accompanying il- 

 lustration. It is, in brief, a tire with an inner tube. 

 Between the cover and the inner tube are a number of 

 recesses or air pockets fitted with valves which are set in the 



walls of the inner tube. The 

 main inflation valve (not shown 

 in the illustration) passes through 

 the rim and into the inner tube 

 and furnishes the air supply. 

 The secondary inflations are 

 practically check valves of sim- 

 ple construction, so that in in- 

 flating the inner tube all of the 

 air compartments are filled. The 

 secondary valves, however, keep 

 the air from leaking out, and as 

 there is a multiplicity of these 

 compartments, in case of punc- 

 ture the tire does not flatten. [Joseph Dupont, No. 77 Stone 

 street, Rochester, New York.] 



THE "EVERST1CK'' INVISIBLE RUBBERS. 

 This is a new overshoe, which simply covers the sole of the 

 leather shoe, but which is warranted to stay on, by reason of 



havingacord circling 

 the entire shoe, that 

 will not stretch. It 

 clings tightly around 

 the edge of the sole, 

 and does not bind 

 the foot in any way, 

 though affording am- 

 ple protection against 

 wet or damp street 

 pavements. It is 

 practically invisible, 

 and may be worn 

 without injury to a 

 patent leather shoe. 

 Though only recently introduced, the sale of these shoes is re- 

 ported to have become large. A number of leading jobbers 

 throughout the country have been named as agents for the 

 owners of the United States patents, Adams & Ford, Cleveland, 

 Ohio. 



CUP END SAFETY NIPPLES. 

 The nipple illustrated herewith is made of one piece of pure 

 rubber. The idea of the "cup end " is to prevent collapsing, 

 and by reason of the special construc- 

 tion the milk flows readily through the 

 cup without jets and streams, which 

 might cause strangling. Figure 1 shows 

 a sectional view of the nipple. Another 

 feature is that the nipple is easily re- 

 versible, which facilitates cleaning it. 

 Figure 2 shows how the nipple is 

 reversed, by drawing the large over 

 the small end. Patented by Clarence A. Lindsay. [The M. 

 Lindsay Rubber Manufacturing Co., New York and Washing- 

 ton.] 



"CROWN " HARD RUBBER CORD ADJUSTER. 

 This simple device is easily placed upon an electric light or 

 other similar cord without removal of the sockets thus obviat- 

 ing slipping, and preventing abra- 

 sion of the connections. It is reli- 

 able, easily adjusted, durable, and 

 can be used with cords of different 

 sizes. When the regular National 

 Code or similar cord is used, it is 

 passed through the larger end of 

 the adjuster, as shown in the illus- 

 tration ; when used with smal 

 cord, the loop is passed through 

 the smaller end first. These ad- 

 justers are being handled by supply 

 dealers throughout the country, 

 and are in extensive use in factories, mills, offices, and other 

 buildings. The manufacturer offers to supply samples free on 

 request. [J. H. Seaman, No. 175 Dearborn street, Chicago.] 



A NEW DISTRIBUTING PAD. 

 In the lettering of canvas book covers old time book men 

 used a leather pad stuffed with 

 cotton, and an untidy, unsatisfac- 

 tory makeshift it was. That is 

 why the pad made of rubber for this 

 work has proved so popular. The 

 rubber part is of a special compound 

 that is neither affected by the oil in 

 the ink, nor the benzine incleaning. 

 It also saves a great deal of time 

 to the worker, and is exceedingly 

 durable. They are sold in sets of 

 three, neatly boxed, for red. blue, 

 and black inks. [The Mattson Rub- 

 ber Co., No. 26 West Broadway, 

 New York.] 

 MR. BAUMANN'S LEGS. 

 The head of the Baumann Rubber Co. has a very marked fac- 

 ulty for producing little novelties that attract attention and 

 command a ready sale. He 

 has of late been devoting 

 himself to a series of toys' 

 that are of the "tongue 

 ball " order, and that are 

 quite original. For exam- 

 ple, that shown in the first 

 illustration is apparently a 

 small rubber ball which, 

 upon pressure, suddenly 

 shoots out a pair of legs 

 that are a surprise to the 

 observer. It is said that 

 the inventor, or some one 

 of his company, was ad- 

 vised that such a toy would not be approved of by a certain 

 New Yorker by the name of Comstock. But that such a posi- 

 tion would be absurd is evidenced by Mr. Baumann's retort. 



" How can he stop it him ? " he said. " Why don't he stop 

 the wind to blow aboudt those Flatiron building? Why not
