hodgman's "duplex" folding bath tubs. 

 The " Duplex " folding bath tub, illustrated herewith in two 

 forms, has been designed especially as a convenience to trav- 

 elers, and is capable of being 

 folded into a very small space, so 

 that it will occupy very little 

 room and be in the way as little 

 as possible when not in use. 

 These bath tubs are absolutely 

 waterproof, the tan colored fab- 

 ric which is used for the outside 

 being coated on the inside with a 

 fine red rubber. With a view to 

 adding to their attractiveness in 

 appearance, the top and bottom 

 on the outside are trimmed to 

 match the inside of the tub. 

 The handles, rims, and uprights 

 are made of spring steel, and 

 when the tub is placed in posi- 

 tion ready for use it is as rigid 

 as the ordinary metal bath tub. 

 The advantages claimed over the 

 folding or adjustable bath tubs 

 now in use are that the " Duplex '' 

 can be carried about when filled, 

 without spilling the contents; 

 OVAL— CLOSED. can be emptied and filled more 



leadily; can be folded into a very small space for traveling; 

 and presents a much neater appearance than any other article 

 of this kind now on the market. These bath tubs are light in 

 weight, rigid and portable, durable, convenient, and hygienic. 

 They are protected by United States patent No. 639,822. They 

 are illustrated herewith in two forms — round and oval — and 

 are supplied in six sizes, the two smaller of which are intended 

 particularly for infants' use. [Hodgman Rubber Co., No. 806

BALDWIN PNEUMATIC TIRE ALARM. 

 The object of this novelty, for which an application for a 

 United Slates patent is pending, is to give an audible signal 



TIRE INFLATED. TIRE DEFLATED. 



when the pneumatic tire to which it may be attached begins to 

 deflate from any cause. It is a simple matter to be able to 

 know when a tire needs attention — after it has become flat, 

 probably as a result of a serious damage. But this Alarm tells 

 the motor driver as soon as the tire begins to deflate, and this 

 may be the means often of preventing serious damage to or 

 destruction of the tread or inner tube or both. This device is

designed to fit any standard make of tires and is easily attach- 

 ed by means of two screws to the felloe of each wheel. The 

 retail price is $2 per set of four alarms. [Baldwin Chain and 

 Manufacturing Co., Worcester, Massachusetts.] 



"DIALITE" MATTING AND TREADS. 



The illustrations show three very neat patterns of rubber 

 matting, made from 

 " Dialite,' which is an 

 specially treated com- 

 pounded rubber for 

 which great durability 

 is claimed. Whether 

 it is greatly superior to 

 the better grades of 

 tread the writer has no 

 information. The merit 

 of the designs, however, 

 speak for themselves, 

 as they are exceedingly 

 neat and effective. One 

 special claim that the 

 manufacturers make for 

 this matting is that it 

 has very high insulating 

 properties and is. there- 

 fore, recommended for 

 switchboards and elec- 

 tric power stations. In 

 addition to the designs 

 here shown the matting 

 is made up in others 

 such as the pyramid 

 pattern and also into a 

 very large line of artistic 

 perforated mats. These 

 goods are made in vari- 

 ous colors, the standard 

 being dark or drab, but 

 reds, or indeed, any 

 colors that go into floor cylinder pattern. 



tiling of rubber are supplied on order. These goods are made 

 in rolls 6 to 12 yards long and any width up to 36 inches. [The 

 St. Helens Cable Co., Limited, Warrington, England.) 



" NOTA-SEAM " GAS AND AIR BALLOON. 



The balloon represented in the accompanying illustration is 

 manufactured in the United States and cured especially for 



this climate. Its production has 



been the result of many years of ex- 

 perimenting, and it is offered as the 

 most nearly perfect balloon manu- 

 factured. On account of its dura- 

 bility, it is offered to the trade as an 

 excellent advertising medium. The 

 " Nota-Seam " balloon will inflate 

 safely to 30 to 36 inches, and remain 

 in perfect shape — for weeks if in- 

 flated with air, and for more than 

 24 hours if inflated with gas and 

 varnished. These balloons are made 

 in solid blue, cerise, red, orange, and 



white, or supplied in boxes of assorted colors, ni.u ^..11 be had 

 plain or printed with advertising matter. [George Borgfeldt
