THE INDIA RUBBER WORLD 



115 



NEW GOODS AND SPECIALTIES IN RUBBER. 



THE "record" vaporizer. 



THIS vaporizer is made of glass and hard rubber — sub- 

 stances not affected by hydrogen dioxide mixtures. It 

 is extremely simple in arrangement, and thus not likely 

 to get out of order. Particularly it has no tubing such 

 as would be liable to clog when using tinctures or balsams. It 



is, therefore, equally effective in 

 the use of oils, tinctures, balsams, 

 and aqueous solutions. A dis- 

 tinctive feature of this vaporizer 

 is that which enables an abun- 

 dant vapor to be produced with a 

 few minims of liquid, thus obvi- 

 ating the waste of unstable mix- 

 tures. This may involve an im- 

 portant item of economy. Be- 

 sides, the atomizer will not spill 

 or leak its contents in case of 

 accidental overturning. A United 

 States patent for this device was issued November 12, 1901, to 

 Immanuel Lundquist. It is being placed on the market by the 

 New York Surgical Appliance Co., incorporated October 10, 

 1901, under New York laws for the purpose of handling this 

 and certain other new specialities. Their address is No. 1244 

 Broadway, New York. The retail price is $1.50. 



THE "SOLID comfort" INVALID RING. 

 A PROGRESSIVE New York house that has already produced 

 many advanced specialties for invalids, has just given to the 

 world a newly patented invalid ring, called the " Solid Com- 

 fort," a cut of which is shown below. In general appearance it 

 does not differ greatly from the old style round rubber ring, 

 although those who know about invalid rings will appreciate 

 at a glance the advantage of the peculiarly shaped oval center. 



When in use, the 

 old style ring with 

 round center 

 swells up in front 

 and back, causing 

 an uncomfortable 

 pressure against 

 portions of the 

 body of the user. 

 This not only 

 gives the user an 

 u n com for table 

 feeling, but is said 

 by physicians to 

 be a frequent 

 cause of irritation 

 in instances of 

 gynecological or 

 rectal affections. This new cushion avoids these difficulties. 

 Another serious objection to the old style ring or cushion with 

 round opening is that there is no room for ventilation when 

 the patient sits on the cushion, the opening being entirely 

 covered when in use. With the oval center cushion, the but- 

 tocks cover only the center part of the opening, leaving the 

 front and back parts open, thus securing perfect ventilation. 

 There being no pressure in the front and back, constriction of 

 the parts is avoided. The cushions have been shown to a 



number of physicians, prominent trained nurses, and hospital 

 superintendents, all of whom appreciate the benefits of this 

 new style invalid riug. Five or six leading manufacturers 

 have already made arrangements with Meinecke & Co. (New 

 York), who control the patents, to manufacture these rings on 

 a royalty basis. The rings are made in three sizes — 13, 15, and 

 17 inches in diameter — and are to be sold at uniform prices by 

 all manufacturers. In this connection it may be stated that 

 the oval center refers not only to the round rings, as Meinecke 

 & Co. have also secured patents on an oval shaped cushion, a 

 square shaped cushion, and a seat shaped cushion, all with 

 oval center openings. The patents are protected against in- 

 fringement by The Patent Title and Guarantee Co. (New 

 York). 



THE LITCHFIELD CUSHION HEEL. 



This heel, for which a patent was issued January 1 5, 1901, to 

 John F. B. Litchfield, Worcester, Mass., is a combination of a 

 recessed rubber cushion, coming next to the heel seat, with one 

 or more leather lifts for the tread. One of the illustrations 

 shows the appearance of the recessed cushion, 

 and the other a sectional view of the heel com- 

 plete. The point is made that the use of this 

 heel "gets rid of sneakiness and stealthiness, 



'/y/////y/y/////y//////M'//////y/////M'////M'//y///////////y//^ 



\ 



which are very potent objections to the outside rubber heel, 

 the leather top lifts and slugs making a noise when walking." 

 Besides, the heel is not slippery on wet ice and mud. It pos- 

 sesses the other advantages claimed for rubber heels. When 



the leather lifts become 

 worn, they can be removed 

 without disturbing the 

 rubber cushion, and new 

 lifts put in place. The rub- 

 ber cushions, made for the 

 owners of this patent at a 

 Boston rubber factory, are 

 sold to leather shoe man- 

 ufacturers, who build up 

 the heels with leather to 

 the desired height. Ar- 

 rangements are now mak- 

 ing, however, to cater to 

 the cobblers' and repairing 

 trades by offering the heel 

 complete. In order to carry on the business of assembling 

 the rubbers and leathers, the owners of the Litchfield patent 

 are looking for a factory site, in some important shoe center, 

 where some of their captial stock can be placed. One town 

 mentioned in this connection is Southbridge, Mass.=> The 

 Litchfield Cushion Heel Co. was incorporated in March, 1901, 

 under the laws of Maine, with $100,000 authorized capital, to 

 exploit the above described heel. Their offices are at No. 828 

 Colonial building, Boston, and No. 74 Russell street, Worces- 

 ter, Mass.
