BALAKCEO WHIP GOLF CLUB. 



As every player knows, the game of golf is not as easy as it 

 looks, but requires the most practiced skill to attain any degree 

 of proficiency. Every improvement in the accessories is 

 eagerly sought by devotees of the game, but while the golf 

 balls of to-day are much more resilient and better than 

 those formerly in use, the chief improvement in clubs has 

 been in the appearance and greater range of selection, the 



y matter of distance and control remaining practically the 

 same. 



An interesting departure is shown herewith in a golf 

 club embodying decided improvement in these qualities. A 

 piece of rubber inserted in the shaft's upper half gives a 

 controlled flexibility which makes it whip only one way, in 

 the direction the ball is driven, instead of up or down or 

 in a circle, in the provoking manner of ordinary clubs. It 

 is claimed that the perfect balance of this club makes it 

 feel lighter and swing with greater freedom and more 

 force, and this, together with the whip, enables the player 

 to gain greater distance and accuracy. It is also said to 

 prevent the breaking of the club at the head, and when 



J played in the rough, striking stones or turf, the whip 

 breaks the .shock and almost invariably saves the club. 

 These clubs are made in a large variety of weights and 

 styles, including all kinds, from driver to putter. [Balanced Whip

HAHD RUBBER SUBJIAHINE .TARS. 



A large percentage of the submarines used by the government 

 has sulphuric acid batteries, and hard rubber jars are required 

 to encase them. The accompanying illustration shows a number 



of such jars that are made especially for the United States Gov- 

 ernment. They measure approximately 12 by 17 inches by 3 feet 

 high, with walls 3/8 of an inch thick. [The Luzerne Rubber Co., 

 Trenton, New Jersey.] 



■ FLOOR TREADS AND MOTOR-CAR COVERS. 



The patent safety tread here shown consists of rubber blocks, 

 vulcanized in galvanized steel, brass or other malleable metal 



plate and form- 

 ing a raised pat- 

 tern. For stair 

 treads and office 

 door mats this de- 

 vice is highly sat- 

 isfactory, being 

 neat in appear- 

 ance, noiseless, and affording an absolutely safe foothold. 

 Waterproof motor-car covers are also furnished by the same 



in use is provided. (The North British Rubber Co., Limited, 

 Edinburgh, Scotland.] 



COMBINATION DASH AND TROUBLE LAMP. 



In ordinary use, this device is a dash lamp, suitable for any 

 car, to illuminate the speedometer, vibrator, clock, pedals, etc. 

 The light is turned on and ofi^ by means of a two-way socket. 



A threaded lock nut on 

 part B holds the lamp 

 head securely in the dash 

 socket, preventing all 

 rattle and wear of parts. 

 When desired, it can 

 be cnnverted into a 

 trouble lamp by simply 

 removing the lamp sock- 

 et B from the dash 

 socket C, using the ten 

 feet of cord fitted with Bayonet plug and socket. The plug A 

 is then connected to the socket D on the dash and the other 

 end to the reflector and lamp B. ' 



These lamps are finished in nickel-plate, the lamp socket and 

 plugs being made of hard rubber, forming the insulating mate- 

 rial, and also supporting the metal plungers and metal contact 

 points which complete the circuit with either the lamp bulb or 

 the plug, as the case may be. [Metal Specialties Manufactur- 

 ing Co., Chicago, Illinois.] 



MARSHALL'S LINEMEN'S SHOE. 



The lineman's calling is a dangerous one and its followers 

 must be fully protected against electric shock. The shoe here 

 illustrated is said to afTord absolute protection, on the poles, on 

 the ground, or in 

 manholes, against 

 pressure up to 20,- 

 000 volts. This 

 shoe is vulcanized 

 into a solid piece, 

 will not peel nor 

 come apart, and is 

 not afifected by oil, 

 gasolene nor grease. 

 The outer surface 

 is of tough red rub- 

 ber, the outer sole 

 of white, wear-resisting, vulcanized tire-tread rubber. Above 

 an insulated sole of red rubber extending two inches above the 

 heel is a non-moisture absorbing cushion, and the lining of the 

 shoe is embedded in rubber to prevent absorption of moisture. 

 The shoe upper is made of "Standwatter" mineral tanned leather, 

 with no glue or grease used in the tanning process. This leather 

 is claimed to be waterproof, current-proof and not affected by 

 heat or cold.
