 ago he joined the forces of the Mich- 

 elin Tire Co., starting as manager o 

 its Cleveland, Ohio, branch. Four years 

 later he was favored with promotion 

 to the management of the Chicago 

 branch, which included supervision over 

 the Minneapolis, St. Louis, Des Moines, 

 Cleveland and Kansas City branches.

 were rewarded by his appointment

LOUIS H. PERLMAN WINS RIM PATENT SUIT. 



Judge Lacombc in the United States Circuit Court of Appeals. 

 New York City, on February IS rendered a decision affirming 

 the findings of Judge Hunt in the United States District Court. 

 who held that the Louis H. Perlman's demountable rim patent 

 (United States patent No. 1,052,270) was valid and infringed by 

 the Standard Welding Co.. Cleveland, Ohio. 



This is considered one of the most important patent decisions 

 affecting automobiles, as it is estimated that 700,000 of the 1,200,- 

 000 automobiles to be constructed this year will use demountable 

 rims. Mr. Pcrlman has stated that it is not his intention to em- 

 l)arrass private automobile owners and that be will require a 

 moderate rovaltv from manufacturers of rims. 



The Jennings-Sullivan Rubber Co., East St. Louis, Illinois, has 

 become local distributor for the ,\cme "Red Letter" tires, manu- 

 factured by the .\cme Ruliber .Manufacturing Co., Trenton, 

 New Jersey. 



THE 'GIANT" TIRE TWELVE INCHES WIDE. 

 Tlie chief object of this tire is to replace dual cquii)meiit for 

 special services, such as on roads with a decided crown, or on 

 unpaved roads. 



The "(jiant" tire is made in llie cliannel steel hard base pressed- 

 on type in tliree sectional 

 sizes, 8, 10 and 12-inch. 

 The 8-inch is oversize 

 for dual 4's having about 

 the same volume of rub- 

 ber as 5-inch duals. The 

 10-inch is oversize for 

 5-inch duals ; that is, the 

 same volume of rubber 

 as 6-inch duals. The 12- 

 inch is oversize for 6- 

 inch, comparing in rubber 

 volume with the 7-inch. 

 As originally made, this tire had an extremely high tread. 

 .\fter thorough experimenting, the design was changed and in- 

 stead of the solid, round section, the present "Giant" has a flat 

 tread, with two circumferential flutes in the 8 and 10-inch sizes 

 and three flutes in the 12-inch. [Firestone Tire & Rubber Co.,

VACUUM CUP SHOCK ABSORBING LINERS. 



By the insertion of vacuum cup shock absorbing liners, rim- 

 cut tires that are practically worthless may be used until the 

 carcass is worn threadbare. It is claimed for the vacuum cups 

 that they eliminate at least 85 per 

 cent of the bearing surface, and thus 

 do away with friction, which is al- 

 ways detrimental to the life of a 

 casing. 



The vacuum cup liner acts the 

 same as an inner shoe and entirely 

 envelopes the tube. The feather-edge 

 coming between the two beads and 

 channel of the wheel, laps over three rows of vacuum cups. 

 Inflation of the tube automatically locks the liner, which is 

 held in position by the action of the vacuum cups. [F. S. 

 Bryant. Reading, Massachusetts.)

THE ■CLINCHER CROSS' TIRE. 



Tlic "Clinrlier Cross" tire shown in the accompanyi: 

 tration is claimed to possess unusual non-skidding 

 under all conditions of road, owing to the unique 

 formation of the tread design. On roads ren- 

 dered dangerous by ice or wet asphalt, this tire 

 is said to possess qualities that render its use 

 safe where steel-studded tires are often danger- 

 ous. The increased thickness of the tread offers 

 large wearing surface, reduces liability to punc- 

 ture and tends to produce high mileage. This tin 

 has seen severe military service upon the con- 

 tinent and the manufacturer claims to posse- ^ 

 records showing 15,000 miles on ambulance wnrk 

 without changing the tires. [The North British 

 Rubber Co., Limited, London, England. |
