GOODRICH WIRELESS IIRE. 



THE Goodrich Wireless Tire has three integral parts — first a 

 special steel base dove-tailed on the top surface ; second, a 

 hard rubber sub-base inseparably united with the steel base 

 third, a soft rubber tread, vulcanized on the hard rubber sub- 

 base. By a spe- 

 cial process of 

 manufacture, the 

 n n i o n between 

 these three com- 

 ponent parts is 

 made permanent, 

 and separation is 

 claimed to be im- 

 possible. No in- 

 ternal metal fast- 



1 ^^^.M enings, such as 



wire, are imbed- 

 ded in the rub- 

 ber. The Good- 

 rich Wireless 

 Tire claims to 

 last longer, to 

 wear better because the rubber compound in the tread is perfectly 

 adapted to the use lo which it is put, and to he more resilient be- 

 cause of the sectional shape of the tire with its duplex curves.

LIGAIURES IN FRANGIBLE TUBES. 



The desirability of ligatures put up in such a way that they 

 are always ready for use at a moment's notice, without any proc- 

 ess of sterilizing, is obvious to anybody. It is some- 

 thing the surgical profession has long wanted. The 

 Scabury frangible tulie ligature appears to comply 

 with these reciuircments. It is put up in a small glass 

 tube and. being absolutely sterilized, is ready for use 

 instantly on its removal from the tube. The accom- 

 panying cut shows one of these frangible tubes, the 

 dark piece in the center being a rubber sleeve which 

 plays an important part in this device. It serves two 

 purposes — first, it enables the tube to be broken with- 

 out cutting the operator's fingers or getting any glass 

 in the ligature, and it also enables these frangible 

 tubes to be shipped without danger, for if they are 

 broken in transit, the break will occur under the rub- 

 ber sleeve — where the tube is made thin and more 

 readily breakable — and the fluid is kept from leaking 

 out. To remove the ligature it is necessary inerely 

 to exert a little pressure at the point covered by the 

 rubber sleeve. The tube breaks at that point and the 

 , upper part can be removed without spilling any liquid 

 or doing any damage with broken glass. The method 

 of using these ligatures is very simple. A little 

 pressure is e.xerted at the thinest part of the tube under 

 the rubber sleeve, which breaks the tube. The sleeve 

 is then rolled back, the upper part of the tube removed 

 ligature taken out for use. [Seabury & Johnson.

RUBBER-PROOFED AEROPLANE FABRICS. 



A number of American manufacturers are making rubber- 

 proofed fabrics for aeroplanes and dirigibles ; but they are not 

 the only ones, as this department of rubber manufacture has 

 received considerable attention on the other side. "Aeroplatte" 



is the name of a rubber-proofed aeroplane fabric made in Eng- 

 land, which is made rubber-proofed on one side, 39 inches wide, 

 with a weight of 3^ ounces per square yard, and also rubber- 

 proofed on both sides, width 38 inches, with a weight of ^Yz 

 ounces per square yard. Both of these fabrics are subjected to 

 a thorough strength test. Their color, it might be added, is light 

 tan. [The Northern Rubber Co., Retford, England.]

RUBBER MATTINGS. 



rubber mattings now so or- 

 namental, and at the same 

 time practical, are two 

 in very original patterns. 

 ( )ne. in cone pattern, as 

 sliown in the illustra- 

 tion, is extremely at- 

 tractive and particularly 

 adapted for use at en- 

 trance ways to halls, of- 

 fices or wherever a heavy 

 tread is necessary. The 

 other is a smooth fish- 

 bone or herring-bone pattern, 

 quite unique and very useful 

 in halls and stairways, aisles or 

 corridors in churches or the- 

 aters, or in any place, public or 

 private, where ordinary carpet- 

 ing would be used. These mat- 

 tings come in rolls 6 yards long, 

 36 inches wide and in colors 

 drab or red. [Dunlop Rubber

"SPRING BELT" WATERPROOFED ROBES. 



The new automobile robe is really a combination of a robe 

 and a bag. It unites the two important functions required of a 



robe for winter driving, i. e.

firstly : complete warmth and pro- 

 tection against the elements ; sec- 

 ondly, the safety of absolute foot 

 freedom and perfect control of 

 the car, so necessary when roads 

 are wet and slippery. It is abso- 

 lutely waterproof, being either of 

 rubber fabric on one side or else 

 with an interlining of rubber. It 

 is not fastened by snaps or buck- 

 les, but by a light spring, 1/16 of 

 an inch thick and 1 inch wide, 

 which clasps the body firmly well 

 up under the arm pits and brings 

 the tw-o ends of the robe to- 

 gether at the back and keeps 

 them there, but can instantly be 

 removed with a pull at the front 

 of the robe. The robe itself is 

 50 inches long and 60 inches wide. 

 It has separate "Footpockets" of 

 iined leather thoroughly water- 

 jiroofed. This robe is as conven- 

 ient for women as for men, and
