LONG DRIVING GOLF BALLS. 



THE three cuts shown herewith represent three different pat- 

 terns of golf balls. The first one is known as the "Arch 

 Colonel" ; the second, the "Green Star Colonel," and the 

 third, the "Crescent Colonel." The first two differ only in their 

 marking, the "Arcli Colonel" having an entirely new sunken mark-

 ing. while the "Green Star Colonel" has an eight-pole pebble 

 marking. The "Crescent Colonel" is a new ball just brought 

 out and is rnarked like the "Arch Colonel," but is a floating 

 ball. The manufacturers of these balls make very confident as- 

 sertions about their long-driving qualities. [St. Mungo Manu- 

 facturing Co. of .America, Newark, New Jersey.] 



THE DIAGONAL BLOCK TIRE. 



A new heavy duty truck tire has Ijeen invented by Albert L. 

 Siegrist, Akron. Ohio. 



The special feature of this tire is that every block is in- 

 dependently demountable without interfering with other blocks. 

 This removal feature is accomplished by the use of two "U" 

 shaped head bolts running downward tlirough the felloe, and a bolt 

 crosswise through the downward flange. With all "bolts in place 

 they become a solid mass, eliminating the strain from any one 

 particular block. 



The blocks are placed on the wheel diagonally, a feature that 

 gives a smooth continuous roll and also prevents skidding and 

 allows for rubber displacement. [The Diagonal Block Tire Co., 

 of Urbana, Ohio.] 



AUXILIARY SOLID TIRES. 



To take the place of the spare wheel usually carried for taxi- 

 cabs and light vans, the Blackwell rim has been devised, which 

 consists of a light pressed-steel rim, of which an integral part 



is a continuous skeleton 

 form of flange. The rim 

 holds a length of light 

 solid tire, and the flange 

 serves to fasten this di- 

 rect to the felloe of the 

 wheel, keeping it in per- 

 manent position on the 

 inside of the wheel. The 

 outer diameter of this 

 inner rim comes within 

 about 3 inches of the 

 ground when the pneu- 

 matic tire is fully in- 

 flated. But when the 

 pneumatic tire is de- 

 flated, this auxiliary 

 solid tire meets the 

 ground and does the 

 work of the incapacitated pneumatic tire ; avoiding the damage 

 that would be done the pneumatic tire if continued in use in its 

 deflated condition. [The Blackwell Rim Co., Stourbridge, 

 Worcestershire, England.]

THE ADAMSON AUTO-VULCANIZEE. 



Many a motorist, when his tire has been punctured far 

 from home, would have given a great deal for a little 3-pound 

 vulcanizer that would have repaired 

 the puncture in 15 minutes. As a mat- 

 ter of fact he need not have given 

 very much, if he had been sufficiently 

 provident to lay in beforehand the 

 y^^^ ' '^i'" Adamson Auto-Vulcanizer, which costs 



y^'-^ T but a few dollars, takes but little 



-' room and is said to repair the or- 



dinary puncture in a quarter of an hour. 



The two accompanying cuts show this repairer at work ; one 

 showing it on the outer shoe, the other clamped to the deflated 

 inner tube. An interesting feature of this small vulcanizer is 

 the fact that its temperature is, to a very considerable e-xtent, 

 under automatic control. When it is 

 needed for a repair, an ounce of gaso- 

 line is poured into it and ignited. After 

 it reaches the proper temperature for 

 vulcanizing, a further increase of tem- 

 perature is avoided by its peculiar con- 

 struction, which is so planned that when 

 the temperature of the gasoline reaches 

 a certain degree, the volume of gas given 

 off b}' it forces the zone of combustion 

 up above the heat-conducting members 

 of the vulcanizer. This permits the vulcanizer to cool somewhat, 

 the flame lowers and the proper degree of heat is again at- 

 tained. 



It might be said in passing that this convenient little 

 vulcanizer has been widely imitated. [The Adamson Mfg. 

 Co., East Palestine, Ohio.]
