New Goods and Specialties. 



THE OEAN NONLOSABLE STOPPER. 



THE Stopper of a hot water bottle is always getting lost or 

 mi.'^placecl just when the family comforter is most needed. 

 A stopper that is always on the job; that cannot be lost; 

 that does not depend on a chain or exterior attachment, 

 would be a boon indeed, and such apparently is the device 

 described and illustrated as follows: 



Closed. Oi'en. Open. 



The inventor has reversed the principle of the old arrange- 

 ment by placing the stopper inside the bottle instead of out- 

 side. A wire handle serves to operate the stopper. To open 

 the bottle simply unscrew and push the stopper down far 

 enough to allow free passage of the water either in filling 

 or emptying. To close the bottle, just pull up on the handle 

 and screw the stopper in place, the rubber washer making a 

 water-tight joint when forced against the upper part of the 

 outer metal socket. This device can be attached to a hand- 

 made bottle as well as a molded bottle with a wide neck.

SOF-LITE HEADLIGHT DIMMER 



The laws of many states compel the use of automobile head- 

 light dimmers to reduce the glare that is confusing and danger- 

 ous. The device we are now describing is made of a single 

 disk of frosted pyralin that diffuses and 

 effectively eliminates the glare of the head- 

 light, yet illuminates the roadway fully 

 100 feet in advance of the car. 



The quick, easy and secure method of 

 attaching this dimmer is a feature that 

 will be appreciated by the motorist. It is 

 held securely in place on the inside of the 

 li( adliL^lit ■.;la^s by a single vacuum cup of soft rubber. [The

RUBBER COVERED TIRE INFIATOR VALVE. 



Garage men who have been annoyed by the carelessness of 

 patrons, who, after inflating tires at their free air station, have 

 neglected to shut off the flow of air, will welcome the new 

 Schrader automatic inflating valve, 

 which has just been put on the 

 market, and which prevents any 

 waste, either before, during or 

 after inflation. The valve is covered with rub- 

 ber for protection. 



This device, which can be furnished with con- 

 nections suitable for different sized hose, from 

 54 to 5^-inch diameter, fits into the tubing of the 

 garage air line, and permits the egress of air only when it is 

 applied to the valve of the tire to be inflated. .^11 that is neces- 

 sary is to hold the inflating valve's nozzle against the tire valve. 

 This opens the valve check in the angle valve, and allows the air 



to come from the rubber tubing into the tire. Immediately the 

 pressure on the tire valve is removed, the valve in the hose 

 automatically closes, and the air pressure remains in the tank.

LIGHT SPORTING BOOTS. 



Many sportsmen would wear rubber wading boots were it 

 not that they are so heavy and clumsy as to be uncomfortable 

 when not actually required for going thmugh the water. An 

 improved, light-weight, storm 

 king style sporting boot named 

 "The Angler" is now manu- 

 factured, which can be worn 

 over the leather shoe, and 

 which, when not in use, is so 

 light and flexible that it can be 

 rolled up into a small enough 

 package to be carried in the 

 coat pocket. The advantage 

 of such a boot is obvious with- 

 out further comment. This 

 particular boot is made of 

 pure gum, is fusion lined 

 and has an elastic top, thus 

 fitting tightly around the leg.

A HANDY RUBBER STAMP. 



pencil cap here reproduced, actual size, is designed for 



a convenient rubber stamp for marking initials on cloth, 



'" paper, or articles of any kind. The desired initials 



are cemented on the plain, broadened base of the 



rubber cap, which fits easily and securely over the 



end of the pencil. In clerical work the advantage 



m the lessening of time and energy consuming 



motions can readily be seen, as the user does not 



have to put down his pencil to pick up a rubber 



stamp, but simply turns the pencil about and 



^ applies the stamping end. [The William Stern

PNEUMATIC REVERSIBLE LANDING MAT. 



When a fire call is received at an engine house, stairs are too 

 slow a method for the firemen in the upper story tf> eain the 

 main floor. The vertical 

 sliding pole gives the de- 

 sired speed. The neces- -. . 

 sity of a landing mat that 

 will minimize the shock 

 of contact with the floor 

 can readily be seen, and I 

 rubber mats are invari- 

 ably used for this pur- 

 pose. But in order to af- 

 ford the proper yield and 

 recovery the mat here 

 shown has been specially constructed. It is ciaimcd tiiai a per- 

 fect pneumatic mat is thus secured, offering a soft, safe and dur- 

 able landing at the base of the sliding pole. Each of the tubes 

 supporting the wearing surface of the mat has a vent into the 

 main air chamber, which is also provided with one or more vents
