Matter That Means a Great Sav- ing in the Expense of Op-
 erating Machine.
NEW DEVICE PUT ON MARKET
Exhibited at Recent Automobile Show in Chicago, 1t Met With the in- stant Appreciation of Those Who Should Know its
 Value

Nothing could apply to the motorist more than the old saying that "a stitch In time saves nins;" it is particularly applicable in the matter of tire repair and tire care. for tires are more abused and more neglected than any part of car. The motorist may not permit himself to believe that he is tori2g comes to a large extent from inattention to the necessity of frs, aid to the injured tire
 Macadam roads are apt to have many loose and sharp-edged stones apparently placed where they will do the most damage possible to tire tread. They will not cause puncture cause a letdown, but they will cause little and big cuts in the tread. Such little cuts do not cause the loss of air. but they make it possible and prob. able that the fabric will be exposed, and when the tire is submerged in a pool of water the damage has com. menced
  gradually loosen the fabric, it will separate the tread from the fabric, and will permit sand blisters-the dirt will gradually creep under the tread and expose more of the fabric to the moisture-with the result that in a short time the inner layers of fabric separate and permit a blowout. And a tire that has been permitted to go until this happens is practically worthless.
 Heretofore it has been a simple mat ter to make good job of repairing a punctured tube, for this does not come in contact with water. but there have not been convenient repair schemes for taking care of a cut casing. One was exhibited at the Chicago automo' bile show. however. which can be op- erated from the current of a storage battery or from the electric light cir cult in the garage. It was small af- fair. in fact, could be carried in pocket. and was designed to be used for yuicanizing either tubes or castings, and requiring only few moments to do a permanent job. This is the inven- tion of a Chicago man. well known in motoring circles.
 A cut in a casing. for instance. is cleaned with gasoline. rubber is placed in the cut, and the vulcaniZer attached in a manner similar to that in the il' ,ustration. Then the current from the storage battery is turned on and the job is finished. except short wait while the vulcanizing is going on. Tn the meantime the motorist prepares another c,,t, if there is one. and by the time this is ready the first one Is ready to release the little instrument.
 The most ingenious wrench ever h-ovgh, 10 the attention of motorist has just been brought out by an Hi nois man. The mechanic who tries it will find nothing it will not do for an inanimate thing. for 1t adjusts itself and tightens itself in most peculiar manner. and will take either 8 large o, small nut, with no danger Of rounding the corners of the nut. one mechanic figured that with several such wrenches in his shop he could .asilv save from 10 to 15 per cent of ,he time usually put on car by urorkman. but he did not state wheth- ~ the owner would be given the bene- a, of this saving. Ordinarily a motor ist carries from three to dozen urenches in his tool kit. whereas this one could easily replace at least hall |. dozen of the set
