A MEW RUBBER HORSESHOE. 



E\'1'1RYB.0DY ought to be glad when things come the horse's 

 way. Here is a new horseshoe that should do a great deal 

 to relieve the horse's burden. It really puts him on a 

 quick-detachable tire footing. The accompanying cut will give 

 some idea of this new shoe. It consists of an iron shoe that 

 is nailed on tlie horse's hoof like any other .shoe. Around 



the outer edge 

 of this shoe 

 there is a flange 

 and on the in- 

 ner edge live 

 lugs, each with 

 a threaded bolt 

 with a square 

 head. This 

 flange and these 

 lugs form a 

 channel, into 

 which is fitted a 

 solid rubber 

 tread, the lower half of it. whicli touches the ground, being 

 resilient rubber, the upper half, which fits into the iron shoe, 

 consisting of rubber and canvas. A layer of stout fabric 

 covers this upper half of the tread, reaching down to the 

 lower or rubber half. This canvas cover makes it possible to 

 screw the bolts in so as to hold the tread securely without 

 damaging tliat part of the tread that comes in contact with 

 the bolts. 



This shoe gives the horse an all-rubber tread, and at the 

 same time leaves the frog of the foot entirely open. When 

 tlie tread is worn out another can be inserted in a couple of 

 minutes by simply loosening and then tightening the bolts, 

 and the iron part of the shoe gets no wear whatever and con- 

 sequently stays permanently on the horse's foot without the 

 necessity of replacing. This new horseshoe was invented 

 and has been patented by G. E. McKinnon, Little Falls, 

 New Jersey.

THE TWIN NURSING BOTTLE. 



youngster who has not yet arrived at the stage of life 

 he is interested in table d'hotes, and must still subsist 

 on milk, has had a good many devices prepared for his con- 

 venience and health. Here is one of the very 

 latest. It is a nursing bottle, very simple in con- 

 struction, consisting of one tube and two rubber 

 caps — one at each end. 



When the cap, or "the breast," as the manu- 

 facturers call it, at one end of the tube is turned 

 inward, it forms a base for the nursing bottle. 

 This base may contain a puncture in the nipple, 

 or not, as preferred. When the nipple is per- 

 lorated, air is admitted to the bottle by way 

 oi the base, which makes nursing easier for the 

 child. This device is easy to clean. [Flygeia

THE LIBBY ANTI-BURSTING DEVICE FOR TIRES. 



An objectionable feature of pneumatic tires 

 on automobile wheels has been that they would 

 frequently burst or blow out, on account of ex- 

 cess pressure within the tire, caused by the ex- 

 pansion of air confined therein, resulting from 

 friction or changes in temperature, or from 

 sudden contact of the tire with obstacles in the 



ruad. This trouble is of comparatively frequent occurrence and 

 has not only proved a source of expense, but has led to many 

 serious and fatal accidents. Moreover, the constant variations 

 of pressure shorten the life of the tire. 



An invention of John K. Libby, of Maiden, Massachusetts, 

 for which a United States patent (No. 1.035,207) has been is- 

 sued, consists of a vehicle wheel having a pneumatic tire, whose 

 interior communicates with an elastic relief chamber. When the 

 pressure of the air in the tire increases, it is exhausted into the 

 relief chamber, thereby preventing an excessive or injurious 

 pressure in the tire. When the pressure in the tire falls, air 

 will be exhausted from the relief chamber into the tire, thus 

 preventing an excessive reduction of pressure in the latter. A 

 normal safe working pressure, according to the inventor, will 

 thus be maintained, notwithstanding variations of temperature 

 within the tire, however caused. 



The device is a mechanical one, composed of metal and rub- 

 l)er and mounted on the hub of the wheel. It is already pat- 

 ented in the United States, and patents have been applied for 

 in Great Britain, France, Germany, Italy and Canada.

THE RUBBER CUSHION HAIR BRUSH. 

 r-cushion hair brushes are not so particularly new ; the 

 hair brush, for instance, first appeared on the London 

 market about twenty-eight years ago. But 

 it is an interesting article, in which rubber 

 plays a considerable part, and it has proved 

 extremely popular. As the accompanying 

 cut shows, the bristles are imbedded in a 

 cushion of rubber. This enables the brush 

 to combine the durability of stiff bristles, 

 together with the yielding effect of the rub- 

 ber cushion, which, in reality, is an air- 

 cushion ; accordingly the brush has a cer- 

 tain pneumatic resiliency. These Pearson 

 rubber-cushion brushes are now made in a 

 great variety. They are made in three 

 sizes : in black and white, cherry, rose, satin 

 and ebony woods. The American agents 

 are Alfred H. Smith Co., 35 West Thirty- 

 third street, New York City. 



A LIGHT SANITARY, INEXPENSIVE FOOT ARCH. 



An Albany physician — or to be more ex- 

 plicit — Dr. John J. Collins, 69 Ten Broeck 

 street, Albany, New York, has invented a 

 new sort of foot arch, made from reinforced 

 hard rubber. It is thoroughly ventilated, 

 which makes it sanitary and cool. It is im- 

 pervious to moisture and is extremely li.ght 

 Moreover, it can lie made flexible by the 

 application of a certain degree of heat, which 

 makes it possible to adjust it to any normal 

 or abnormal condition of the foot. Another 

 point in its favor is that it can be manu- 

 factured very inexpensively, so that it can 

 be put on the market at an attractive price. 

 The doctor, who has other affairs to attend 

 to, has never put this arch on the market or advertised it, and 

 he is willing to dispose of the patent (which has 14 years to run) 

 and the molds at quite a reasona'ole figure. This arch has been 

 examined by other physicians and highly commended by them. 

 Here appears to be a chance for somebody to acquire a good 

 foot arch on favorable terms.
