trials, and for which a patent has been applied, aims to give a 

 truck greater speed, as well as to effect a marked saving in gaso- 

 line. Some of the advantages claimed for this design and con- 

 struction are that a more uniform cure can be obtained in manu- 

 facture, less internal heat is generated while in use as the tire is 

 <;emi-air cooled, the traction wave is practically eliminated, and 

 greater traction and resiliency obtained through more rapid dis- 

 placement. The design is such that it is an individual block tire, 

 each block set alternately on a permanent hard base. — II. H. 

 Boucher, 1308 West Pico street, Los .Angeles, California. 



A RUBBER BOTTLE-CONTAINER 



The accompanying illustration shows a new bottle-holder or 

 container, which may be made of rubber, rubberized fabric, or 



rubber compounds. It may 

 be decorated in any way de- 

 sired, by using colored rub- 

 bers, and it may be in any 

 shape or size to fit bottles of 

 different kinds. The sides 

 are corrugated to prevent 

 rolling if it happens to tip 

 over, but there is an extend- 

 ing flange at the bottom 

 which forms a small air 

 cliamber or vacuum when 

 the holder is placed firmly 

 on a flat surface, and this 

 vacuum helps hold the bot- 

 tle and cover in an upright 

 position. The open end is finished with a heavier band of rubber 

 which grips the bottle firmly. This device is intended to minimize 

 the cracking of bottles from shock as well as to prevent light 

 from getting at their contents, and to preserve heat and cold in 

 contained liquids. — Mrs. Catherine Flannery, 16 Hakes avenue, 

 Hornell, N. Y. United States patent No. 1,381,071.

DUST CAP AND TIRE GAGE COMBINED 



An ingenious invention that combines the features of a dust 

 cap and pressure gage for tire-valve stems is the "Test-O-Cap," 

 which, it is claimed, saves time, tires and 

 gasoline. 



The cap screws on over the valve stem 

 and is adjustable to the required pressure. 

 Its functions are to guard against either 

 under or overinflation and in order to 

 test the pressure it is necessary only to 

 press a small plunger at the top. If the 

 cap rises the tire is properly inflated. If 

 it rises so far that a projecting arrow- 

 point travels above the bottom edge of 

 a red band that circles the cap, the tire 

 is overinflated. Failure of the cap to 

 rise at all signifies underinflation. .\t 

 one side of the cap is a connection for 

 the pump hose. — The Greist Manufactur- 

 ing Co., New Haven, Connecticut. 



"2-PLEX" INSULATING TAPE 



Under the name "2-Plex," a combina- 

 tion rubber and friction tape for use in 



electrical insulation is being marketed.

 side black. It will withstand a heat of over 200 degrees P., it is 

 claimed, without crystallizing or vulcanizing. This tape is J4-'nch 

 wide, is put up in J^-pound rolls, and comes wrapped in heavy tin- 

 foil. — Diamond Holfast Rubber Co., .Atlanta, Georgia. 



SCIENTIFIC NURSING-BOTTLE NIPPLE 



The "Dominion Nurser" has a special holdfast, anti-colic 

 feature in the shape of the lower part which fits inside the neck 

 ^^ of an eight-ounce, round, graduated bottle with 



IB semi-wide neck, and allows a passage of air be- 



^X^^^ tween the nipple and the neck of the bottle while 

 ^I^^P the child is feeding. The nipple also has a pro- 

 ^^^ ^^\_ jecting flange about half way up from the bottom, 

 s ■ 'i|gi which covers the top of the bottle and prevents 



^■im ^mK:^ the food from leaking out. If babies could express 

 their opinions, doubtless they would give this in- 

 vention their unqualified approval. 



To remove the nipple from the bottle it is only 

 necessary to insert the finger and thumb below the 

 middle flange, pressing the nipple together slightly 

 and letting in the air. It will then come out easily 

 and can be readily cleaned. The manufacturer of 

 this red rubber nipple also puts out the special 

 bottle on which to 

 use it, and this 

 bottle, on account 

 of its wide neck, 

 can be readily 

 washed and kept 

 entirely antiseptic 

 by proper scalding. 



NEW "FLEETFOOT" SANDAL 



The "Romper" barefoot sandal 

 is a two-strap model of the "Fleet- 

 foot" line, made of white duck, 

 with leather insole and counter, 

 white rubber sole and white fox- 

 ing, and is made in sizes for 

 misses and children. The same 

 manufacturer produces both nip- 

 ple and sandal.— Canadian Consolidated Rubber Co.,

CORD TIRE FROM THE MID-WEST 



The "Black Hawk Chief" cord tire is said to possess many re- 

 finements over the ordinary cord tire. Its outside dimensions are 

 larger than standard cord tires and it is heavily reinforced at the 

 rim to prevent cutting. The side-walls 

 are protected by an unusually heavy 

 coat of tough rubber which prevents 

 the scuffing so common to cords. 



The several types of pneumatic 

 automobile tires manufactured by this 

 company are guaranteed to be free 

 from imperfections in material and 

 workmanship. Out of 15,0(10 manu- 

 factured only twenty-two were re- 

 turned for adjustment. The company 

 claims that its tires are built for hard 

 usage, and have been proved equal to 

 the emergency when used on rough 

 country roads. 



The same manufacturer also is fea- 

 turing "Black Hawk Sturdy Traveler" 

 inner tubes of red rubber with a wide 

 jet-black stripe of specially tough- 

 ened rubber around the tread. It is 

 claimed that this tube cannot rust to
