nerves. By the simple device of a cushion heel plate of rub- 

 ber such as the Cat's Paw, our two noble lej^s, thus well 

 hecleil, become a skid proof rubber tired wheel, whose motion 

 approaches the ease and grace of a barefooted child on the 

 grass. [Walpole Rubber Works, No. 170 vSunimer street,

AN AUTOMATIC AIR BRAKE COUPLING. 

 Aiu brakes are of such general use and importance, that 

 an automatic air pipe coupler, such as this, would naturally 



attract attention. The two, or 

 =>C2 <WQ'T=CC3=IIJl]Br\ rather the four members, which 



constitute this coupler, are sup- 

 ported by the cars. The joint 



^fAr rS=^=a:i:a:£inni:^ '® made by two U tubes, which 

 =af^ l^~V \i—liUiX4y ^^ .^^^^ ^^^^^ other. The limbs 



of each U lube form a male and a female member, which 

 fit air tight with the corresponding female and male mem- 

 bers of the other. Ivach female member bears a guiding 

 funnel, for the reception of the male member of the coupling. 

 Kach male member bears a nipple or piston of rubber, while 

 the female members are lined with rubber. Thus, the 

 coupling is automatic and air tight. The great danger 

 which was formerly connected with the coupling of cars has 

 now been removed by the automatic car coupler. The coup- 

 ling of air brake hose does not carry with it such a consider- 

 able element of danger, yet there is a certain risk, and a con- 

 siderable delay connected with the present method, both of 

 which would be eliminated by the use of the autotnatic air 

 pipe coupling. [Pietro Setting and Peter Hoover, patentees,

THE 'KANTLEEK'' WATER BAGS. 



Speaking of hot water bags recalls the drummer "down 

 East " who was accustomed to make a little money go a 



long way, like 

 good rubber. 

 In response to 

 a strong inter- 

 nal demand, 

 he had stopped 

 by the roadside 

 for lunch ; but 

 before he had 

 taken more 

 than a few 

 bites, was 

 seized of a vio- 

 lent painamid- 

 ships, and 

 cried aloud in 

 his agon}'. In 

 answer to his 

 pitiful gasps, 

 a rescuer took 

 his (the drum- 

 mer's) water bag, filled it with 

 boiling water, and laid it 

 gently over his in 'ards. Re- 

 covering instantly, the suf- 

 ferer proceeded to warm up 

 several fried eggs and slices 

 of meat on the water bottle, 

 and then poured out of it a 



cup of hot coffee, and thus made a good meal. This biography 

 is not meant to point a moral, but to illustrate some unusual 

 uses of the hot water bag. The most authentic manuscripts 

 do not say whether the bag which he used was a " Kant- 

 leek," but it probably was, because it did not leak. The 

 Kantleek hot water bottles, fountain syringes, face bags, 

 and ice caps are made for different uses, and in fashions dif- 

 fering from each other; but all bear the celebrated "Red 

 Seal " trade mark, and are sold with the manufacturers un- 

 qualified guarantee. It has been said that plenty of cold 

 water on the inside and the outside will cure four-fifths of 

 the ills that human flesh is heir to. Local applications of 

 hot water will relieve other ills not amenable to cold water. 

 The Kantleek goods will attend to the whole matter of hot 

 or cold local outside applications, and will cover several 

 branches of the inside applications. If there were but one 

 hot water bag in the world, it would be worth a million or 

 so, but the Kantleek make so many, that they can sell them 

 cheap, in various sizes, in red or white and will even cover 

 them with softest eiderdown for a trifling consideration. 

 Their syringes and ice caps are also made in beautiful style, 

 in various sizes and shapes, of pure white rubber, with satin 

 finish. [Seamless Rubber Co., New Haven, Connecticut.] 

 AN ENGLISH VACUUM DUST EXTRACTOR. 

 Removi.vo dust from carpets while lying on the floor of a 

 room is by no means a novelty, but it has heretofore been 



done by high power 

 machines stationed in 

 the street in front of 

 the house, or b)' more 

 or less expensive plants 

 installed in the base- 

 ments of large build- 

 ings. The air current 

 necessary to remove the 

 dust is carried through 

 a rubber hose pipe to 

 a receptacle outside 

 into which the dust is deposited. The utility of the vacuum 

 process is generally recognized, its cost being the only thing 

 that has prevented its taking the place of the old fashioned 

 broom and dust pan method to a large extent. It has re- 

 mained for an Englishman to invent cheap apparatus that is 

 intended to take the place of the big machine. He has con- 

 trived a bellows like box which is fitted with the necessary 

 tubing and attachments and containing a vacuum pump that 

 is operated by foot power somewhat after the manner of a two 

 pedaled sewing machine, the bellows box resting upon the 

 floor of the room while the machine is in use. [The Witch 

 Dust Extractor Co., Birmingham, England.] 

 A NEW PUNCTURE PROOF TIRE. 

 A NEW skid and puncture proof tire protector is illustrat- 

 ed herewith. The tread is of stout material, the skid feature 

 being gained In' the projection 

 of numerous rivet heads. With- 

 in the body of the protector is a 

 puncture resisting layer com- 

 posed of overlapping strips of 

 metal, too thin to interfere ap- 

 preciably with the resiliency, and yet practically imper- 

 forable. These metal strips are held in place by having thin 

 layers of rubber vulcanized between^them, and rivets passing
