MAXWELL PERFECTS
 NEW 0|L|NC CLUTCH

"Grab" and fierce" are two terms which bring to the mind of the man who drives a motor car vivid pie lures Of clutch troubles, and while clutch troubles are usually hot so serious as diseases of the motor, transmission or rear axle, they are of sufficient magnitude to fill the nightmares of motorists with hor- TOTS easily the equal of those which come from eating mince pie at mid night. For unalloyed annoyance the grabbing" clutch has no rival.
 Strange as it may seem, in the earlier days of the development of the motor car, the clutch got less attention from engineering depart ments in motor car factories than any other vital part of the cars anatomy, and the general rule seem- ed to be to tackle the trouble of all other parts first and leave the clutch problems until the morrow, which, of course, never came.
 Johnny, bring me those blueprints on the shelf marked clutch" the chief engineer would say to the of l flee boy. But by the time Johnny had gotten the dust brushed off the prints the whistle blew and every body quit for the night. Tomorrow brought work from other part of the factory, and the clutch prints were put back on the shelf. When they had been there a week or two the performance was repeated, the whis- tie blew according to cue, and the motorist continued to wonder why in thunder they didn't put better clutch in the new Ghogetter car
 During the past year or two, how
 ever, since many cars have reached
 what is almost the highest degree
 of mechanical perfection, greater at-
 tention has been given to the design
 and construction of the clutch, witt
 the result that the efficiency of this
 part in a number of makes of cars
 has improved greatly.
 An instance of this improvement
 is the clutch of the Maxwell, whicl
 IS the only cone clutch designed t,
 run in bath of oil. In speaking O. this exclusive Maxwell feature yes
 terday, R. D. Roper. local dealer
 said; ''In my opinion, the Maxwell
 clutch is now the most scientificall,
 designed clutch ever placed on tn
 market. When it was designed, tn Maxwell engineering staff were tol,
 to produce a cone clutch whic]
 would engage quickly, firmly an,
 quietly; a clutch which would To generate an excess of friction be tween its gripping surfaces, and on that would disengage as readil and as quietly. There should be m , damage done to other parts of th car when the driver threw in tn clutch too rapidly, and the necessit : for careful ''feathering" of the clutc I should be overcome. Also the lin l ing surfaces should be so durabl , that they would hold without per ! ceptble wear for thousands an . thousands of miles of motoring.
 The Maxwell engineers studie $ various types of clutches and hi
 on the idea of making a clutc
 which should run in bath of Iigh l motor oil. Trials proved this clutc I to be so thoroughly successful ina n patents were sought to keen th Q running in oil feature exclusive wit . the Maxwell so far as cone clutche n are concerned. Today all Maxwe F cars are equipped with this perfee ', clutch, and the 100000 who drov 2 Maxwell cars are unanimous that tr . Maxwell clutch has rendered fl = terms grab" and fierce" obsolet
