A PLATFORM FOR HIGH-PRESSURE STREAMS. 



It is often a very liazardous matter to hold the nozzle of a 

 fire hose on an icy pavement, a slippery street, or a slanting 

 roof. The illustration shows a small and conveniently handled 

 device that makes it perfectly possible for a single person to 

 manipulate the nozzle of a hose pipe no matter how uncertain 

 the footing or how high the pressure. It is a small oblong 

 platform which can be folded up, and when folded is only about 

 20 inches long and 10 inches high; it weighs only 20 pounds. 

 This can be opened and put down on a slanting roof or an icy

pavement, and nothing can budge it, because there are several 

 sharp prongs on the lower side that take hold and keep hold. 

 The upper surface of this platform is covered with rubber to 

 protect the firemen from electric shocks from streams that strike 

 highly charged wires. Near the center of the platform there is 

 a socket which holds the extension rod of the "Perfection" 

 holders, also made by the Eastman Company. The accompany- 

 ing cut shows the Eastman platform in conjunction with one of 

 the Eastman Perfection holders. By the use of this combined 

 platform and holder, the stream can be directed at any angle and 

 under all possible pressures. A great many city fire departments 

 are equipped with these Eastman outfits, the Baltimore Fire 

 Department having recently adopted this system for its million- 

 dollar high-pressure service. (,The Samuel Eastman Co., Con-

FINE IF IT ONLY WORKS. 



From time to time the general consumer is cheered by a para- 

 graph — that turns up once in so often in the columns of the 

 newspapers — telling him how rubber articles that have lost their 

 elasticity can be brought back to their original estate. The ad- 

 vice usually reads something like this paragraph, taken from a 

 recent number of a western paper : 



"People using articles made of rubber that frequently lose their 

 elasticity through oxidation may restore the material to its 

 original condition by a simple process. Soak the article in a mix- 

 ture of one part of ammonia to two parts water. This is par- 

 ticularly well adapted to the restoring of rubber bands, rings and 

 small tubing which are ready to become dry and brittle." 



Soaking rubber goods in a mixture of ammonia and water is 

 simple and easy, but, unfortunately, there is one drawback — it 

 doesn't work. The only way to remedy a rubber band that has 

 turned hard and brittle is to get a new band.
