Waterproof bags for tire inner tubes are also supplied. The 

 same tirm are marketing rainproof Rubber Cloth Covers, which 

 are a practical article for the protection for automobiles in 

 certain situations. These have been made in varying sizes up 

 to 150 inches wide by 260 inches long. [The Gilbert Manufac- 

 turing Co., New Haven, Connecticut.] 



THE GOODRICH WIRE WRAP. 

 This type of wire, for armoring rubber hose, was originated 

 for the purpose of overcoming certain unsatisfactory fea- 

 tures of other wires in use, and 

 is the subject of United States 

 patent No. 726,730. It is de- 

 signed to add to the life of 

 hose which is subjected to 

 hard usage and liable to be 

 dragged over rough places. It 

 is made with a tin projection 

 on the underside of the wire, 

 which, while giving a firm 

 grip, does not cut or other- 

 wise injure the hose. This 

 prevents the wire from slip- 

 ping, and holds it m p. ace. The wire can be supplied flat or 

 round, as desired. [The B. F. Goodrich Co., Akron, Ohio.] 



"diamond" soft cover battery jar. 

 The patented battery jar illustrated herewith is designed es- 

 pecially for automobiles, electric 

 railways, and electric lighting 

 plants. It is constructed with an 

 '/i inch wall — ^^ of an inch hard 

 rubber, and over this .,'5 of an 

 inch soft rubber — with a view to 

 easing any shock the jar may 

 receive in handling or other- 

 wise, and keeping the jar 

 whole, even if the hard rub- 

 ber should become cracked.

NOVEL NURSING APPLIANCE. 



Alice Frank of New York has obtained a United States 

 patent (No. 773,252) on the device illustrated herewith, which 



embraces a nurs- 

 ing bottle holder, 

 with means of at- 

 taching the same 

 to a bedstead, 

 chair arm, or the 

 like ; also means 

 for retaining heat 

 in the food holder 

 for an indefinite 

 period. The bot- 

 tle holder consists 

 of two hinged and 

 spring actuated 

 shells, provided 

 with a non conducting lining, and a holder for supporting 

 the shells in position. The patent further relates to a flex- 

 ible arm attached to the holder, and a clamping device at- 

 tached to the opposite end of the arm. Instead of an infant's 

 feeding bottle, a suitable liquid or solid food receptacle may be 

 substituted, and the form of the shells modified in order to sup- 

 port the same. 



ST. JOHN NON PUNCTURABlF. AUTOMOBILE TIRE. 

 In the tire illustrated herewith a cushioning, or resilient, ef- 

 fect, is secured by piercing a series of round holes sidewise 



through the 

 rubber, be- 

 tween the 

 planes of the 

 tread and the 

 rim. It may 

 be described 

 otherwise as 

 having a tread 

 surface and a 

 r i m surface, 

 each continu- 

 ous, and hav- 

 i n g between 

 them a number 

 of rubber cush- 

 ions, at equal 

 distancesapart, 



the openings between the cushions aflfordingthe resilient effect. 

 The tire is referred to as being designed to eliminate all 

 trouble from punctures, rim cutting, leaky valves, and the like, 

 and the necessity of inflating. The tire is made in one piece, 

 and fastened to the wheel by a series of bolts. It is made to 

 fit any ordinary rim. The invention is covered by a United 

 States patent granted recently to H. N. St. John. [St. John 

 Rubber Co., No. 1 16 Broad street. New York.] 



A NOVELTY IN RUBBER MATS. 

 The illustration relates to a mat which comprises an elastic 

 body having pockets therein, and metallic liners of said pock- 

 ets having 

 scraping edges 

 designed for 

 effectively re- 

 mo v in g dirt 

 from the shoes, 

 besides which 

 destructive 

 straining of the 

 elastic body 

 due to c o m- 

 pression is avoided because 

 the liners relieve the elastic 

 body of severe strain. By 

 extending the openings 

 entirely through the body 

 the mat is reversible, and 

 either the bottom or top surfaces can be used, and upon 

 removal of the mat the dirt can be removed. But in case it 

 should be desirable to retain the dirt in the mat so that the 

 dirt and mat can be removed together, a bottom of fabric may 

 be secured to the under surface of the elastic body. At the 

 left of the cut are shown illustrations of two forms of the me- 

 tallic liners, though the invention is not confined specifically to 

 these forms. United States patent No. 771,809, issued Octo- 

 ber II, 1904, to Arthur S. Burnell. [Queen Manufacturing 

 Co., Marshalltown, Iowa.]
