THE WORLD'S ADVANCE

is almost meaningless to the majority of 

 suit buyers. 



In order to avoid disappointments to 

 the clients as well as make the selection 

 of different cloths a simple matter, a New 

 Yorker has invented a simple device 

 which he calls the "instantailor" or "gar- 

 ment stimulator," and on which any piece 

 of cloth that may be selected can be 

 placed in order to demonstrate to a client 

 how the finished suit will be. No cut- 

 ting is required to secure the effect of 

 a finished suit. 



As may be seen in the accompanying 

 illustration, the "instantailor" is adjust- 

 able for height as well as girth. The 

 tailor, after adjusting the form to the 

 size of his client, has simply to pass the 

 bolt of cloth over the device and place 

 the framework over it. The result is a 

 finished suit which can be carefully ex- 

 amined by the client in order to deter- 

 mine whether the color and pattern of the 

 cloth will be pleasing. 



To Secure the Effect of a Finished Suit from Any 

 Piece of Cloth is the Purpose of a Simple Frame- 

 work Known as the Instantailor. 



A Clear Telephone Line from a Subscriber to the 



Central Office is Possible with the Use of This 



Automatic Locking Device Recently Invented. 



DEVICE WHICH PREVENTS LIS- 

 TENING ON PARTY LINES 



An automatic locking device which 

 prevents eavesdropping and interruptions 

 on party lines will be of interest to many 

 telephone subscribers. The lock weighs 

 less than a pound and can be carried in 

 the vest pocket. It may be connected to 

 the telephone it serves or to the terminal 

 box from which the several lines are dis- 

 tributed. The action is automatic, the 

 mechanism being composed of a series 

 of magnets and contacts which are 

 brought into operation when a receiver 

 any place on the party line is removed 

 from the hook. A clear line from a sub- 

 scriber to the central office is made auto- 

 matically by the magnets and contacts. 

 Telephone engineers have tested the in- 

 vention and it is said to have worked 

 properly and promptly. 



BUOY LOCATES LOST SUB- 

 MARINES 



One of the latest inventions to . be 

 brought out as a result of the war is a 

 signal buoy, attached to a submarine. In 

 case of an accident to the submarine the 

 buoy is automatically released and floats 

 to the surface, indicating the point where 

 the submarine has sunk. A long reel of 

 wire which pays out automatically an- 

 chors the buoy to the wrecked vessel. 

 The buoy is held firmly in a steel case 

 on the deck of the submarine by electro- 

 magnets.
