SHAVING BY PNEUMATIC AID, 



Thousands of fortunate people are now able to ride to their 

 morning labors on pneumatic tires. These same people and 

 thousands of others can start the day by shaving (if they so 

 elect) with pneumatic assistance. Some inventive genius in 

 Connecticut (.the whole rubber industry is based on the inven- 

 tion of a Connecticut genius ) has de- 

 vised a mirror called the Aero Safety 

 Mirror, with a rubber edge and rubber 

 back. This rubber back, being slightly 

 concave in form, can be pressed against 

 a window-pane — the raised rim being 

 slightly moistened — and will remain 

 there when tlie hand is removed, be- 

 cause a slight vacuum is created, and 

 the mirror is held by the pressure of the 

 air. In other words it is a suction 

 mirror. This mirror is of use not only to shavers, but to others, 

 as it can be used in any place where there is a smooth surface to 

 press it against. For instance. ladies, after a 60-miIe jaunt in an 

 auto can put the mirror up in front of them to see how much is 

 left of their complexions, and how much awry their bonnets are. 

 The rubber back and raised rubber edge also prevent the glass 

 from breaking should it happen to fall. [.\ero Sales Co., Hart- 

 ford, Connecticut.]

SUCTION PUMP rOR CLEANING PIPES.

 ping-up of a drainage pipe with the resulting overflow of bath-

 of the pump is a double lip vacuum cup. [George W. Heilani),

A NEW TIRE VALVE. 



This tire valve is made by The Burke X'alve Co., Cleveland. 

 Ohio. It differs from the regular valves in many w^ays. First, 

 the valve stem is made in two parts, so that if it becomes bruised 

 at any time on the end the end stud can be changed for a new 

 one instead of changing the whole valve. This has a lead gasket 

 to insure a tight joint. Second, the plunger has no spring, being 

 a balanced valve ; the pressure in the tube equaling that of the 

 pump, so the valve closes automatically. Third, this valve has 

 three ports for air to pass through, so that when pumping up a 

 tire it can be done in very much less time. Those who pump up 

 their tires by hand \vill be surprised at the ease and rapidity 

 wMth which the tire is inflated. It has another good point — the 

 reversible valve seat, of rubber, which rests in a metal recess in 

 the valve seat. 



"VULCAN-SET IN RUBBER' SHAVING BRUSH. 



From its general adoption the safety razor has evidently 

 come to stay. One of the results is that the individual shav- 

 ing brush has in many cases become an indispensable toilet 

 adjunct for the sterner sex. This widely extended use has 

 encouraged manufacturers to meet the demand for better 

 brushes and this has been effected by the "Vulcan-set in 



Rubber" shav- 

 ing brush. The 

 bristles and 

 hair are first 

 imbedded i n 

 rubber of best 

 quality in a 

 plastic condi- 

 tion, which is 

 then vulcanized as hard as granite, by which means it be- 

 comes impossible for the former to be loosened. The brushes 

 are made by new machinery especially constructed for the 

 purpose, and every bristle is firmly locked in its place, being, 

 moreover, not liable to injury by heat. 



This brush has been adopted as the standard by the United 

 States Navy, having been re-ordered in January, 1912. after 

 experience of its use during the voyage round the world of 

 the White Squadron. The makers claim to be the largest 

 brush manufacturers in the world. [John L. Whiting-J. J. 

 Adams Co., Boston, Massachusetts.] 



THE "SIOUX CHIEF • BOW AND RUBBER-TIPPED ARROW. 



Old as history, archery has still a living interest as an 

 outdoor sport. While its main features differ only in de- 

 tail from those known in ancient times, these de- 

 tails in themselves constitute appreciable improve- 

 ments. Archery has at all times been a favorite sport 

 of young people, and it is largely for their benefit that 

 much enterprise has been shown by manufacturers in 

 this line. 



In this connection the "Sioux Chief Bow" claims 



to represent the latest developments. It is a steel 



bow with a hardwood arrow. The bow and hand- 



II piece are of polished nickeled steel 26 inches long, 



ijl while the arrow is of polished hardwood 15 inches 



V-fi long, with soft rubber tip and weighing only eight 



ounces. 



With the above advantages and its low retail 

 price of 25 cents, it is considered likely to do much 

 to revive the former taste for archery contests.

NEW RUBBER WATERPROOFING LlaUID FOR LEATHER. 



The waterproofing of leather by means of oils as 

 hitherto practiced by tanners, has had the disadvantage 

 that the oils quickly wear off, leaving the leather in a 

 hard and unsatisfactory condition. "Leakanot" is the 

 result of many years of painstaking efforts to obtain 

 rubber in such form that it will penetrate and be ab- 

 sorbed by leather. It wears off very slowly, leaving 

 the leather perfectly soft and pliable, ready for an- 

 other coating after many weeks of wear. 

 -Xnother distinctive advantage of "Leakanot" is that it 

 does not discolor tan leather; thus appealing particularly to 

 ladies wearing light colored shoes and to men of particular 

 taste in their footw-ear. 



For retail trade it is put up in large 50-cent containers, 

 sufficient to waterproof several pairs of shoes, thus being 

 calculated to last the individual customer at least one year.
