preferably by the cold process, to obviate the possibility of the 

 stock softening and thereby losing its characteristic surface ap- 

 pearance. It is therefore better to effect the cure by dipping 

 for a short time in a weak solution of sulphur monochloride. 

 [Goodyear's Metallic Rubber Shoe Co., Xaugatuck. Connecticut. 

 British patent No. 100,727.] 



Method and Apparatl'S for Reclaiming. Rubber scrap of 

 different densities is reduced to a pulp in water which is mixed 

 with a heavy oil, and air is admitted to the bottom of the tank 

 causing the particles of low specific gravity to rise to the sur- 

 face with the oil, while the heavy particles settle. The film 

 on the surface containing the lighter rubber is skimmed off by 

 a slowly moving endless conveyor, while the heavier particles 

 which settle are removed by the same means. [Thomas J. 

 Pennington, Chicago, Illinois. United States patent No. 

 1,195,264.]

MISCELLANEOUS PATENTS. 



CORD TIRE FABRIC. 



A CORD fabric tulje is built with two Ia_vcrs of rubberized 

 •'^ cord, the inner layer laid at right angles to the axis of 

 the tube, and the superposed layer comprising cords extending 



from the tread 

 line diagonally 

 half way around 

 the tube, and 

 then diagonally 

 back to the tread 

 line. [John F. 

 Ives, Cleveland, 

 Ohio. United 

 States patent X'o. 

 1,194,388.] 

 A similar pat- 

 ent granted to the same inventor covers a two- 

 ply fabric strip composed of two layers of rub- 

 berized cords, the inner layer extending at right angles to the 

 edges, and the superposed layer extending diagonally from the 

 center to the opposite edges of the strip. [John F. Ives, Cleve- 

 land, Ohio. United States patent No. l,194,3cS9.] 



SAFETY PRESSURE GAGE. 



The inventor of this device has combined an air pump con- 

 nection with a pressure gage that may be set to the required 

 tire pressure, and when this point is reached the excess air 

 escapes with a whistling sound. In the 

 drawing, the upper is a sectional view and 

 the lower one a side elevation of this device. 

 The gage being connected to the tire valve 

 stem at A, the tube B is attached to the air 

 supply, and the barrel C adjusted to the de- 

 sired pressure on the scale shown in the 

 lower figure. When this pressure is reached 

 the air acts on the piston, coiriprising a tubu- 

 lar member D and an annular member /;', 

 forcing back the spring F, and causing the valve (/ to move 



away from the valve H. This allows the air to escape between 

 them, and to flow through the opening / and the sleeve J, caus- 

 ing the whistle K to indicate that the desired pressure has been 

 reached. [Frederick A. Schroeder, assignor to the Hill Pump 

 Valve Co. — both of Chicago, Illinois. United States patent No. 

 1.196,142.] 



TIRE PRESSURE INDICATOR. 



In the accompanying illustration, the drawing on .the left is 

 a front elevation of this device, showing the valve and pressure 

 indicating dial. Referring to the central drawing, the end of 



the tire valve is attached 

 at A, and the gage part 

 B is forced down by hand 

 to the position shown in 

 the drawing on the right. 

 Tints the stem C will un- 

 seat the pin in the valve, 

 and air from the tire will 

 pass upward around the 

 stem, through the opening 

 II and into the gage, 

 wliich will indicate the tire pressure on the dial. If additional 

 air is required the manual pressure is removed from the dial 

 and the air pressure raises the gage to the position shown in 

 the central figure. Then air from the source of supply freely 

 passes through the opening F into the central opening, and 

 thence through the valve into the tire, the pressure being suf- 

 ficient to unseat the valve. [James W. Frazier and Fred E. 

 Hansen, Cleveland. Ohio. United States patent No. 1,196,226.] 



GoLP Ball. This patent provides an inner rubber bag or 

 container filled w'ith liquids of different specific gravities, one 

 of which is mercury. [William R. Kjiight. Belleville, assignor 

 to St. Mungo Manufacturing Co., Newark— both in New Jersey. 

 United States patent No. 1,194,751.] A similar patent granted 

 to the same inventor was illustrated in The India Rubber World, 

 September 1, 1916, page 662. i 



Leak Alarm. A rubber bulb is made integral with the inside 

 of the inner tube and provided with a whistle which gives an 

 effective alarm when the tube becomes deflated to a predeter- 

 mined extent. [George W. Wells, assignor to Walker- Wells 

 Co. — both of Amesbury, Massachusetts. United Statec patent 

 No. 1,195,883.] 



THE UNITED KINGDOM. 



Rubber Covered Rollers. Rollers of the cushion type with 

 a metal core around which rubber tubing under fluid pressure is 

 spirally wound and an outer sleeve applied and vulcanized, have 

 been covered in British patent No. 2,606, 1915, by the inventor of 

 the following patent. The present invention relates to means 

 for preventing the spiral tubing froin creeping endwi.se. [Jabez 

 Muskett Pendleton. Manchester, England. British patent No. 

 15,001 (1915).] 



Hard Rubber Stcraoe Battery Separator. A thin hard rub- 

 ber separator is molded with longitudinal ribs on the sides be- 

 tween which are additional ribs formed on one or both sides of 

 the separator, tapered, thickened portions being provided at 

 the ends to obviate longitudinal breaks, and it is then finished 

 by punching perforations in the thin portions. [The India Rnl)- 

 ber Co., New York City. British patent No. 100,994.] 



Coating Pneumatic Tires. This device provides a circulation 

 of air within the inner tube and through an outside tube so that 

 the air within the tire will remain cool during travel. This is 

 obtained by attaching an annular tube to the spokes of the wheel 

 and connecting it to the inner tube of the tire, the air circnlatiiV4 

 freely between both tubes. [P. J. Cuddihy, Rutherford, New 

 Jersey. British patent No. 100,897.]
