This Automobile Signal Takes 

 Place of Your Hand When 

 Rounding a Corner 



THROUGHOUT the country it is 

 the practice of motorists, when 

 they are about to turn a corner, to ex- 



A red disk, raised by pressing a button, 



takes the place of the motorist's extended 



hand in making a turn 



tend the arm out of the car at the side 

 toward which they intend turning. 

 Drivers have learned to look ahead for 

 this notice. The unusual signal here 

 shown comes nearer to the extended 

 arm than anything that has thus far 

 made its appearance. 



Upon approaching the corner the 

 driver of the car, which is equipped with 

 a pair of these signals, simply presses 

 a button which is located at the top of 

 the body near the side of the seat. As 

 this button is pressed it operates a 

 mechanism, which in turn swings this 

 arm-signal outward from the side of the 

 car so that it may be plainly seen by the 

 driver of the machine that is following. 

 When the corner has been turned, the 

 button is again pressed, this action per- 

 mitting the signal to drop down against 

 the side of the car. This signal is 

 equipped with a red disk for use dur- 

 ing the hours of the day and a tiny elec- 

 tric lamp for night driving. 



We are told by experts that seventy- 



five per cent of the driver's steering 

 ethciency is lost the moment the arm is 

 extended outward from the side of the 

 car. By the use of this device the hands 

 of the driver are upon the wheel when 

 the corner is actually being rounded. 

 The arm of this signal is about fourteen 

 inches in length, twice the thickness of 

 the ordinary lead pencil, and the disk is 

 about six inches in diameter. With the 

 exception of the disk and the globe, the 

 contrivance is painted black, and every- 

 thing except the small lamp is mechani- 

 cally operated. The device is the inven- 

 tion of W. F. Irwin of Los Angeles, Cal. 



A Safety Wringer-Guard 



AS wringer rolls revolve very rapidly 

 when operated by an electric motor 

 the element of safety to the hands of 

 the laundress is important. A new 

 wringer-guard has appeared, the in- 

 ventor of which has kept this in mind. 

 In feeding the clothes into the wringer 

 the hands are kept at a safe distance 

 by this guard, the opening of which is 

 large enough for bulky pieces, like 

 blankets. The guard may be attached to 

 either side of a reversible wringer. 



The need of a guard to prevent injury to 



the fingers in an electric wringer has been 



met by this device
