THE NEW YOEK TRAFFIC SOUAD IN WHITE RUBBER UNIFORMS. 



N experiment of importance to the rubber trade is now 

 A , being made in New York City. It consists in trying out 

 ^ *■ a new rainy day uniform for the police traffic squad. A cer- 

 tain number of these men have been allowed to discard their black 

 helmets and raincoats. 

 and in their place I 

 don white rubber uni- 

 forms, which distin- 

 guish them at a very 

 considerable distance 

 and issist both officers 

 and drivers of vehicles 

 in the regulation of 

 traffic. The illustration 

 shows a traffic police- 

 man in one of the new 

 uniforms, with boots, 

 coat and cap cover all 

 v\ white rubber. Th< si 

 uniforms have been 

 submitted as samples. 

 i illowing a suggestion 

 made in a recent traffic 

 conference at New 

 York police head- 

 quarters on complaints 

 that driver.- were una- 

 ble at any distance on 

 foggy or rainy days to 

 distinguish policemi n 

 from street railwa\ em- 

 ployes and pedestrians. 

 This is an argument 

 that can scarcely be of- 

 d in excuse for 

 violation of traffic regulations or orders at the corners presided 

 by these white-clad policemen. Should the experiment work 

 out to the satisfaction of the department interesting possibilities 

 would be opened to dealers in rubber goods not only in New 

 York, but in all other large cities. [The B F. Goodrich Co.,

"TWO-PART" FIRE HOSE. 

 Fire hose made in two parts, an outer casing and an inner 

 tube, either of which can be repaired or replaced when worn, 

 i- a new and decidedly interesting development. The lining or 

 inner tube is made specially strong at either side, where the 

 bend conies, by reinforcements of rubberized duck, the spaces 

 between giving it elasticity. This is to overcome the liability 

 of hose to crack at the sides when folded over. It is also made 

 the bends or where it is turned back at each end of 



the wagon, where the severest strain comes. This lining is 

 inserted in the cotton jacket, to which it is fastened only at the 



lings. 



,1 onlj can the inner tube be removed and a new one sub- 

 stituted, but it can be repaired, exactly as a tire tube, while in 

 the event of injury to the casing from burning or any of the 



various accidents to which it is liable, it can be replaced at 

 about half the cost of the hose. By this mode of manufacture, 

 also, a new lining can be supplied at nominal cost lor any fire 

 hose now in service in which the lining has become worn or 

 useless. The manufacturers believe this new hose to be durable, 

 practical, economical and a great advance in the art of hose 

 manufacture. [Chicago hire Hose Co., Chicago.] 



TIRE INFLATING AND GAS TUBING. 



I he accompanying illustrations show two new types i flexi- 

 ble tubing. The first, or tire inflating type, is made with an 



armor of interwoven galvan- 

 ized steel wire over a heavy 

 rubber tube. This armor pro- 

 tects the rubber tubing, en- 

 abling it to stand a pressure 

 ^^ up to 200 pounds, without in 

 any sense decreasing its 

 flexibility. The other 

 is a new type of rubber 

 packed flexible metal 

 gas tubing. The sides of 

 the metal strip are 

 brought close together 

 in the winding, and a 

 rubber thread lies in 

 the groove thus formed. 

 This tubing has been 

 brought out to meet the 

 great demand for a 

 flexible metal gas tub- 

 ing that will not leak. 

 It is different in con- 

 tour from the usual 

 American type, follow- 

 ing in style the German product — than which it is said to be 

 even a little more flexible — now unobtainable on account of war 

 conditions. [Breeze Carbureter Co., 250-252 South street. Jersey

DENTAL POLISHERS AND MEDICINE CUPS OF RUBBER. 



In dental work a rubber polisher, attached to and operated 

 1\ a mandrel, is applied to the teeth, the soft rubber surface 

 spreading itself out and conforming to their contours. A screw- 

 embedded in the soft rubber forms the means by which it is 

 attached to the mandrel. These polishers are made in several 

 different shapes, so that every portion of the tooth can be 

 reached. The small cut herewith shows a new type, 

 called the "B S," for use in polishing the necks and 

 roots of teeth. Another rubber device in use in the 

 dental office is the counter-irritant cup, a soft rubber 

 -uction cup for the application of medicines to the 

 gums over the roots of teeth, after the filling of root canals 

 and in cases of inflammation. The rubber suction cup, with its 

 inner or concave surface medicated as required, is applied to 

 the gums, the remedy proving much more effective than would 

 be the case were it simply applied and then allowed to spread 

 over the mouth. 



Purified gutta percha is the basis of "Oleo-Percha." a com- 

 position described by its makers as "the one perfect canal seal- 

 ing and the only root sealing made from the best grade of pure 

 gutta percha." This preparation is made by a non-secret formula, 

 the gutta percha being purified by methods peculiar to this par- 

 ticular company. [Young Dental Manufacturing I o., St. Louis,
