NASAL SYPHON 



The accompanying illustration shows 

 the method of using the new Nichols 

 nasal syphon which is designed to 

 benefit sufferers from all inflammatory 

 conditions of the nose, and to be used 

 as a preventive sanitary device rather 

 than as a curative means. 



.Ml parts of this syphon are made of 

 rubber ; the tubing and water-bag of soft 

 rubber and the slide and nose-pieces of 

 hard. The device operates by means of 

 the suction force supplied by the outlet 

 tube, which is in direct proportion to the 

 perpendicular drop of the tube. This 

 suction is induced by the creation of a 

 partial vacuum in the head wheji both 

 nostrils are stopped with the hard rubber 

 perforated plugs. — Herbert B. Nichols,

UNIQUE SUCTION-CUP SOLE 



A new variation of the familiar suction-cup sole is found in 

 the sole and heel of this rugged bal intended to withstand the 



hard wear and tear a 

 strenuous boy will be 

 likely to give it. 



The particular feature 

 of this shoe is the "Du- 

 uie.x" suction sole which 

 is studded all over with 

 double suction cups. The 

 toe-cap, upper edge of vamp, eyelet pieces, and ankle patch arc 

 made of leather and serve to reinforce those parts of the shoe. —

WINDSHIELD WIPER OF RUBBER AND FELT 



The stamp of approval of the Underwriters' Laboratories on 

 a manufacturer's product carries with it to the public mind a 

 certain weight of confidence, .\niong such 

 products is the "Auto Scope" windshield wiper, 

 shown herewith. It is of the sliding type that 

 is adjusted on the top of the windshield and 

 consists of a double squeegee rubber wiper for 

 the exterior of the glass and a single felt wiper 

 for the interior. This windshield wiper is con- 

 sidered standard by the Underwriters' Labora- 

 tories when installed on windshields adapted for 

 its use. — White Products Co., 2204 Michigan

TWO NEW BLOWOUT PATCHES 



Tile up-to-date automobilist may now choose 

 between the colors of his blowout patches to 

 go on either white or black tires. The one 

 shown in the picture is intended for use on 

 a black tire but its running mate is white, to 

 harmonize with tires of white rubber, both 

 patches being otherwise similar. 



The new patch is made of high-grade fabric 

 woven from long-staple combed cotton, satu- 

 rated with pure rubber and not merely filled. The new feature 

 of the patch is the red rubber tip designed with a feather edge to 

 insure it remaining snugly against the casing without friction or 

 creeping, and make the 

 thickness less near the 

 bead of the tire. All 

 sizes of these patches 

 except the three-inch 

 have seven plies of 

 fabric ; the three-inch 

 has six. — Firestone
