A TOY MONOPLANE THAT SOARS. 



HE interest in airplanes has siininlated tlie production 

 of toys for the youngsters that shall have some of the 

 characteristics of the real airplane. The one shown in the 

 accompanying illustration, called the "Joy-Toy Soaring Mono- 

 plane," will ascend straight into the air for more 

 than 100 feet and spiral back to the feet of the 

 sender. It has wings of tough paper supported by 

 Hght metal stays on hardwood doweling, and these 

 wings fold up like a fan. A light spring holds 

 them in position when spread. A strong sling or 

 catapult has a broad rubber band with a ring for 

 attaching to the monoplane, and the height to 

 which the plane ascends depends on the power 

 given it by the force e.xerted on this sling. The 

 small sketches show the means of attaching the 



sling and the position in which the monoplane is held when 

 sending it into the air. The air resistance holds the wings closed 

 until the plane has reached the top of its flight, when they 

 automatically spread open. The direction of the toy can be 

 regulated by adjusting the rudder, which is detachable. (The 

 Evanston Supply Co., 118 North La Salle street, Chicago, 111.) 



A WORK-SHOE WITH RUBBER SOLE. 



The tremendous increase in the cost of footwear has opened 

 the way for the popularization of a work-shoe that can be 

 marketed at a reasonable price, and that will give good value 

 for the money paid. A shoe which answers the requirements is 

 illustrated here in so graphic a manner as to require but little 

 further description. 



It has an upper of heavy brown canvas, with a lining of 

 lighter duck, a sok of tough rubber, a fiber counter and insole, 

 and a resilient bo.x-toe. The rubber heel is of. pneumatic con- 

 struction, with several specially constructed chambers which 

 draw in and eject air at every step, thus being lighter and more 



resilient than the ordinary rubber heel. The shoe is made on 

 the Munson last, the shape approved by the Government for its 



Army shoes, in regular lace, blucher, and scout patterns, for men, 

 boys and youths, women, misses, and children. It is in all a 

 most desirable shoe for the purposes intended. (Hood Rubber 

 Co., Watertown, Massachusetts.) 



AN AUTOMATIC INFLATING VALVE. 



A new valve for use in garages and service stations is 

 covered with rubber to protect 

 it from injury and at the same 

 time prevent it from scratching 

 or injuring the body of the 

 automobile near which it may 

 used when inflating tires. An automatic 

 ture guards against the escape of com- 

 ssed air, if for any reason the supply is not cut 

 "SciimDEB i'ni- "•* ^^'hen the use of the valve has ceased. This 

 v£KSAL Infl.iting \iilve is made in four sizes from 5/16-inch to J4- 

 inch. and a patent has been applied for on the 

 device. (A. Schrader's Son, Inc., 783-803 Atlantic avenue, 

 Brooklyn, New York.) 



DETACHABLE RUBBER HEEL. 



A cushion rubber heel made in two lay 



principle of the mortise-and-tenon jnint, is - 



panying sketch. One of the layers 



is permanently attached to the heel 



of the shoe, and the other, beiiiy 



detachable, is easily replaceable 



when worn. The two rubber parts 



may be made of two grades of 



rubber if desired, the upper one 



receiving less wear than the tread 



member. The inventor who has 



patented the idea calls attention to the possibility of 

 utilizing it in applying a rubber facing to the sole or 

 a portion of the sole of a shoe. (Walter H. Clarke, 

 Akron, Ohio.) 



A WESTERN NON-SKID TIRE. 



The tire shown herewith uses a double diamond 

 tread to produce its non-skid feature. This tire is 

 of the clincher type and is a new brand being manu- 

 factured by a western concern. It is called the 

 "South Bend" tire. (International India Rubber 

 Corp., South Bend, Indiana.) 



A SPONGE-RUBBER 

 TIRE FILLER. 



A nev,- substitute for the 

 customary pneumatic tube m 

 automobile tires is made of 

 sponge rubber produced by a 

 special process which toughens 

 it to withstand hard wear. The 

 "Rubber .'\ce," as it is called, is 

 manufactured in different sizes 

 to fit various tires. It is 

 claimed for this tire filler that 

 it will not harden or crumble 

 and will retain its resiliency, 

 while it is not affected by • Im i tk \ , Iiee Fillee. 



natural heat or cold. The 



manufacturer guarantees its invention for one year. (Lafayette 

 Rubber Co., 610O South La Salle street, Chicago, Illinois.
