THE INDIA RUBBER WORLD 



261 



tlio appariiitly calm and unafraid, in all tin- grandeur of his 

 forest solitude. The water of the lake reflects the golden yellow 

 of the western sky at twilight, and the pine-clad hills of the 

 background are enveloped in that blue haze that heralds the 

 coming of a clear, starry night. This picture, expressive of 

 the majesty of nature, is mounted on a background of black, 

 the body of the card being in light brown with a ^ inch black 

 border; and the hanger as well as tlie cord that attaches the 

 calendar pad is of green silk. 



The J. II. Stedman Co., scrap rubl)er merchants, of South 

 Rraintree, Massachusetts, have sent out a very handsome and 

 useful calendar showing, on a background of white, a photo- 

 graph, in shades of browMi, of the Chain Bridge over the 

 Merrimac at Deer Island — the lirst suspension l)ridge ever built 

 in the L'nited States and the second in the world. This is the 

 eighth in a series of New England scenes. 



The Essex Rubber Co., Inc., of Trenton, New Jersey — makers 

 of mechanical specialties — have distributed calendars of the 

 lithographed poster variety, in two styles, each 12 inches wide 

 by 17 high and witli a calendar part attached to this card, the 

 entire width of the card and 7 inches in length. These ad- 

 vertise in effective manner the "Essex"' rubber sole and the 

 ■'Tred-Lite" rubber heel, one picture showing, in red and green 

 on a tan background, a young woman in tennis costume in the 

 act of replacing her slippers with oxfords of the rubber-soled 

 outing variety, and the other, in black and shades of brown on 

 a green background, showing a young man seated in a chair 

 tilted back at a comfortable angle, in a reflective and contem- 

 plative mood — induced proba1)ly by the cigar he has been smoking 

 and the ease afforded by his rubber-soled and heeled oxfords. 

 Posters in the same styles are also supplied without the calendar, 

 but with hanger attachment and cardboard support for window 

 or counter display. 



The Portage Rubber Co.. of .\kron. Oliio, liave favored their 

 friends with a very chaste and tasteful little desk calendar con- 

 sisting of a small monthly pad mounted on a standard about 4 

 inches wide and 4 or 5 inches high, made of solid brass. In some 

 cases they have etched the recipient's name in a little panel left 

 for that purpose at the top of the standard. To many people this 

 personal touch will undoul>tedly add to the .ittractiveness of the 

 calendar. 



The Derby Rulilur Co., Derby, Connecticut — manufacturers of 

 reclaimed rubber — have distributed a calendar for the month of 

 January in the form of a panel about 5 x 10 inches, the upper 

 half of which is devoted to a scene entitled "In the Northland. " 

 The picture lives up to its title, as it is a scene of snowy peaks 

 and general northern cold. .A hunter tramps along the fore- 

 ground on his snowshoes, while a iirocession of rugged Eskimo 

 dogs pull a sled that presumably carries the camping equipment. 

 The company states that it has twelve of these "Close to Nature" 

 pictures, one for each month. 



The North British Rubber Co., Limited — which is generally 

 conceded to he the largest rubber manufacturing company in the 

 British Empire — sends its customers and friends a large wall 

 calendar giving a bird's eye view of its great plant at Edinburgh. 

 At the center of the card is a calendar pad with a leaf for each 

 day and figures of sufficient size to be legible at a very con- 

 siderable distance. 



Elbert O. Jeralds. of 13iS Broadway and 47 West Thiny-lourtb 

 .street. New York — representative of The Canton Rubber Co. of 

 Canton, Ohio — has supplied the trade with a very dainty little cal- 

 endar 7 inches wide and 14 inches in height with a 3^2 x 8 inch 

 center panel showing, on a dark brown background, a young 

 woman in street costume of tan with brown furs, the touches 

 of red on her green hat and at her throat harmonizing with the 

 charming pink freshness of her cheeks. This panel is mounted 



on a gray card which in turn is mounted on white, the calendar 

 part and the ribbon hanger being also in white. 



The Electric Hose & Rubber Co. of Wilmington, Delaware, 

 with branches at New York, Philadelphia, Chicago and San 

 ■•"rancisco, which makes a specialty of rubber hose, has sent 

 to its friends and customers a desk pad 9 x S'A inches in size, 

 which coniliines the offices of calendar and daily memorandum 

 pad. 



The Dunlop Tire & Rubber Goods Co., Limited, whose head 

 offices and factories are located at Toronto, Ontario, and having 

 branches not only in the east but in many of the principal cities 

 throughout the western provinces, distributed a lithographed 

 wall hanger conveying greetings for Christmas, 1913. This pic- 

 tures the "shade" of a departed bufifalo, which, on viewing the 

 industrial progress of the country in which he once ranged 

 unmolested, exclaims "My, how my trail lias changed !" 



David Bridge & Co., Limited, manufacturers of rubber ma- 

 chinery, of Castleton, Manchester, England, have sent us an 

 especially handsome and useful pocket diary, hound in brown 

 leather, w-ith divisions in the inside of the cover forming com- 

 partments for postage stamps, bills, etc. The book is divided 

 into two parts, one containing a number of pages devoted to 

 general and useful information, calendar and space for daily 

 memoranda, addresses, etc., and the other half of blank pages, 

 the space between being provided with a pocket which contains 

 .ui unusually attractive little pencil. 



"The West India Committee Circular," l.S Seething Lane, 

 London, has forwarded a calendar 9x6 inches in size, with a 

 view in colors entitled "The Sunday Market in .Antigua." 



HOT AIR VULCANIZER. 



In the past it has been found difficult to vulcanize rubber by 

 means of hot air on account of the uneven temperature which 

 usually prevails in different parts of the apparatus. The device 

 illustrated in the accompanying drawing, however, is claimed to 

 solve this difficulty and to make vulcanization by means of hot 

 air as efficient as by any other process. The large steel tank A

is closed at one end and has a hinged door B at the other. In- 

 side the tank is a steam coil C which is heated from a steam 

 generator on the outside. -At each end of the tank is a small elec- 

 tric motor D communicating with a fan E on the inside. During 

 the entire period of vulcanization the fans are kept in motion in 

 order to stir up the air and maintain an equal temperature in all 

 parts of the tank. The vulcanizer may be made in any shape and 

 size to accommodate tires or smaller rubber articles, while the 

 heating of the interior may be effected by means of coils of any 

 shape, placed spirally or lengthwise. If desired, a steam jacket 

 may be substituted in place of the coils. The fans may be oper- 

 ated by any availa'ole source of power through a belt from a line 

 shaft, altho electric motors are preferable for this purpose.
