F undercut brasswork

Embossed or undercut brasswork may be easily cleaned by boiling the pieces in a strong solution of fcaustfc soda or 1ye, and then imInersIng them in 8 mixture of hydrochloric acid, six parts; water, two parts. and nitric
 acid, one part, until they become coV-
 cred with dark deposit. Take them
 from the solution and remove the Nhlack substance with fine scratch
 brush After cleaned in this manner,
 rinse in hot water and dry in hot saw
 dust.
 A fine orange-yellow tinge may be
 given to the brass by substituting an
 equivalent weight of powdered alum
 For the nitric acid in the solution.
 The breaking of pump driving
 shaft or coupling, and consequent dis
 ablement of the pump. need not Of
 necessity cause dismay, provided care
 is used If it Is possible, remove the members of the pump which prevent
 the free flow of the water through it.
 If this is not possible. disconnect the
 pump altogether and place a straight
 riece of hose between the radiator and
 the water jacket manifold. If the ra-
 diator is filled to the top. thermosf-
 phonic circulation is set up. but the circulation is not nearly so fast as with the pu1np SC that the spark should be fully advanced and due eau ton exercised so that the motor will not oEefheat.
 Though it is practically impossible in public garages to be rid of a cer- tain amount of dampness because of the activities of the washer, condi- tions in private garages where no washing is done are different. and if proper precautions are taken to open windows and doors after a car that has been driven in the rain has been housed the effects will be beneficial. It scarcely is necessary to point out that dampness causes rust and tar r.ishes the bright work. Therefore, if the garage is kept as dry as possible, care being taken to air it out occa- siona1ly, less application of elbow grease te the brass will be necessary and rust will not attack the iron and steel parts.
 Chattering, ore of the frequent an- noyances of brakes of the double shoe type, is most apt to occur when the arranged as to engage first at the end of the shoe away from the pivot, The result of such an engagement is that the drum tends to draw one of the shoes into engagement ahead of the actuating mechanism, When the spring resists this the shoe oseiiIates slight ly, causing the entire machine to shudder very pereeptfb1y, With a weak spring or with ah excessive of lost motion in the mechan- ism the same effect a1se may occur when the design is perfectly correct. To correct the tendency it is necessary to first determine that the mechanism is free from lost motion, and then that both shoes engage uniformly and as nearly as possible throughout their whole surface at the same instant. When no other remedy will work, the of one of the several fabric lining materials fer the meta! shoes usually will dc the trick
 Considerable stir was created in the automobile world when the publishers of the Automobile Blue Books filed a bill in equity, claiming extensive in of copyright by the Auto
 mobile club of America. The bill goes rather minutely into particulars of wholesale pirating of Automobile Blue Book route data for use in the A. C. Tour Books of 1908 g. 10-1I
 And, while the bill asks for no speci- f1c dama ges, the Blue Book company they feel to be an imposition on mo toring interests in general. On the details of the infringement, however, the bill is most explicit; it alleges that clubs Tour Books have enjoyed is due largely to the fact that an appreciable fraction of the routes Gin all editions from 1908-11) were, wholly or in part, lifted in each case from the Automo- bile Blue Books of the year previous.
 E. R. Mixer. general manager or the Blue Book Publishing com pany, consented to make a brief additional statement to the effect that, while the matter pirated had almost or necessity been appropriated full season late, it was not entirely a mat ter of keeping a competitor "sweatin' and stealin~ year and 'alf beind"- ter the reason that the Blue Book owes it to the touring public to pro Lect their (and its own) interests.
 Depite all runors to the contrary which have been freely circulated Motor Speedway has not been touched by the flood which has held Indianap- olis in it's grasp during the past week and the Speedway management reports that not a dollars worth of property with the big race track has lated on high ground northwest of In- Annapolis and was several miles re- 1 moved from the flood zene.
