A PATENTED HAIR-CURLER. 



A RECENTLY patented hair-curler which is very simple in 

 construction, is shown in the accompanying illustration. 

 It is formed of a loop of wire, aluminum being used in the 

 one seen, with the ends coming together beneath the band around 

 the smaller end. The wire is fle.xible enough to permit the 

 insertion of a rubber ring between the ends, 

 and this ring is positioned within the small 

 loop and held in place by the band. The 

 rubber ring is stretched lengthwise, after 

 tlie hair is curled around the wire, and is 

 slipped into the inwardly projecting crotcli, 

 where it remains securely holding the hair. 

 This device is patented in Canada, although 

 the patentee lives in the States. (M. J. 

 Peppard, Minneapolis, Minnesota. 



THE "ILANASILK" LIFE-SAVING GARMENT. 

 Tlie great demand of the Government for life-saving garments 

 with which to equip the various units going overseas has stimu- 

 lated the production of such 

 .suits and various concerns 

 are putting them out. Of 

 course, they are all different, 

 yet alike in that they consist 

 outwardly of a rubber gar- 

 ment of more or less simi- 

 lar character. These rubber 

 outside suits are made by 

 the American Rubber Co., 

 Boston, Massachusetts, and 

 l)y the Hodgman Rubber Co., 

 Tuckahoe, New York, being 

 supplied by them to the dif- 

 i e r e n t independent com- 

 panies holding the patents 

 ' 'H the several types. 



The "Ilanasilk" suit is 

 composed first of all of an 



inner jacket padded with kapok which is 



sufficiently buoyant to maintain a person 



in the water without sinking. In order to 



protect the wearer from exposure and wet. 



the rubber suit is added. The feet of this 



are weighted to assist further in holding 



(he person in an upright position, and 



there is an elastic fabric opening at the 



neck, through which the head is put. The 



large opening in the front, by w'hich the 



suit is put on, is closed by twisting it 



together and folding it back on itself for 



insertion in a strap extending from the 



shoulder. The air is forced out of the 



suit by pulling it slightly away from the 



neck and squatting. A hood with goggles 



is attached to protect against rough water 



and winds. (The Ilanasilk Lifesaving 



Garment Co., Inc., 27-35 New Jersey Rail- 

 road avenue, Newark, New Jersey. 



A NEW SUPERTIRE. 



A new cord supertire is illustrated here, 

 each cord of which is separated from the others and insulated 

 bv rubber. It is of multiple-ply construction and has a thick 



side- wall above the bead. The tread is jet-black and the side- 

 wall, pearl-gray. The new tire is made in live sizes at the 

 present time. (The Amazon Rubber Co., Akron, Ohio.) 



HARD RUBBER CHEMICAL TANK. 

 A comiilicaled piece of molded hard rubber is shown in the 

 picture below. It is approximately 30 liy 

 10 by 10 inches over all and is used as a 

 chemical tank for an electrolytic process 

 l{arthen-ware boxes were previously used 

 but, while considerably less expensive in 

 initial cost, showed a much greater loss 

 tlirough breakage. Hard rubber was then 

 cliosen on account of its ability to with- 

 stand the action of acids, its dielectric 

 and mechanical strength, and because 

 rd rubber can be molded more accu- 

 rately than most other substances. (The 

 P.. F. Goodrich Rubber Co., Akron, Ohio.) 



THE "STELASTIC" GAS-CONTAINER. 

 This container for compressed coal-gas 

 used as motor-car fuel is made under the 

 Torkington patents, from hard drawn 

 steel wire with tensile strength of 120 

 tons per .square inch, tinned to prevent rust, in correctly pitched, 

 interlaced spirals. The weaving is as strong laterally as longi- 

 tudinally, to withstand internal pressures up to 2,000 pounds 

 per square inch. Each end of the fabric is "gathered" together 



and over it slipped a forged steel ring electrically welded. 



the gatherings beyond the ring are driven six conical lead 



wedges, each about three inches long. Inside of the container 



i.-, a rubber bag made of the best quality of thin rubber. It has 



a gas pipe at one end and is reinforced with plies of cotton 



fabric around the pipe seating. The weight of a cylinder four 



feet long by eight inches internal diameter is 



27 pounds complete, and the capacity is 1.39 



cubic feet. At 20 atmospheres it contains 27.8 



cubic feet of free gas; at 40 atmospheres, SS.6 



cubic feet, and at 70 atmospheres (1,000 



pounds), 97.3 cubic feet. (Stelastic Tires, 



Limited, 76 York street, Westminster, London.

ANOTHER CUSHION WHEEL. 



\'arious types of wheels are constantly beinji 

 devised to mitigate the evils of vibration, and 

 one form of these is the resilient wheel. This 

 one has a rubber cushion (see arrow) inserted 

 between the wood felloe and the solid tire, 

 otherwise being of conventional design and 

 construction. The wheel with the rubber 

 cushion applied is pressed into the outer chan- 

 nel band, the transverse bolts screwed up, and 

 the pressed-on tire put into place. All bolts 

 have countersunk heads on the outside of the 

 smoothness. (Morand Bros, and Martin Cushion Wheel Co.,
