THE INDIA RUBBER WORLD 



[May 1, 1913. 



THE FAULTLESS RUBBER CO. WINS ITS SUIT. 



The United States Circuit Court of Appeals, for the Northern 

 District of Ohio, recently rendered a decision favorable to the 

 Faultless Rubber Co., in an interesting suit brought against 

 the Star Rubber Co., of Akron, for infringement of its "Kant- 

 choke Nipple," patent No. 926,011. The Faultless Rubber Co. 

 owns patent No. 926,011, issued to it June 22, 1909, as the 

 assignee of Thomas W. Miller. The subject matter of the 

 suit was a nipple for nursing bottles. The specification stated 

 as one of the objects "to prevent any contraction of the opening 

 from the body .portion into the mouthpiece of the nipple under 

 compression of the same." The claim said to be infringed was 

 claim 1, reading as follows: 



"1. A nursing nipple, embodying a mouthpiece, a neck, and 

 an intermediate body portion flaring from said neck to receive 

 the bead of the bottle neck, the upper wall of said body por- 

 tidn projecting inwardly at an acute angle from its point of 

 greatest width to form a substantially flat wall, the diameter 

 of the opening from said body portion into the mouthpiece 

 being relatively small in comparison with the diameter of said 

 body portion." 



In rendering its decision the court stated : "We agree with 

 the Board (of Examiners) that the specification and drawings 

 disclosed a novel combination giving a useful, new result, and 

 entitled to protection by patent. One practical difficulty which 

 Miller sought to avoid was the collapsing of nipples while in 

 use. Evidently, a mere tube, when bent sharply to one side 

 or when pushed inwardly so as to make a bend, would collapse 

 and close. It is the patentee's theory that in the Ingram nipple 

 (taken as the best type of previous nipples) the enlarged body 

 portion is still so characteristically a tube that if the mouth- 

 piece is pushed inwardly or bent to one side, either the opening 

 into the mouthpiece or the two together will collapse; .while, in 

 the Miller device, this upper part of the enlarged body portion 

 is I so predominantly a diaphragm that it cannot break over, 

 and instead, it yields longitudinally to a push or pull, and 

 when the mouthpiece is turned sidewise, the diaphragm also 

 turns. The arch of Ingram would resist against a sidewise 

 bend of the mouthpiece, and the opening into the mouthpiece 

 would collapse, but the diaphragm yields and the mouthpiece 

 remains open. This result, as a new and useful result, seems 

 probable enough on inspection of the patent and the earlier 

 patents, and observation of samples, as far as they were sub- 

 mitted to us, confirms this idea. In any event, the utility of 

 the new combination is probable enough, evidenced, as it is, by 

 extensive public adoption., so that the defendant who has copies 

 cannot be heard to deny such utility." 



Accordingly, the court grants the usual interlocutory degree 

 for injunction and accounting against the defendant company. 



INFRINGEMENT SUIT DECIDED IN FAVOR OF THE FISK RUBBER CO. 



In a recent important decision — which it would take two and 

 one-half pages of this publication to reproduce— the United 

 States Circuit Court of Appeals, for the First Circuit, affirms 

 the decree of the District Court which held that the claims of 

 United States Patent 822561 to P. D. Thropp were invalid by 

 reason of anticipation. 



Suit was brought against The Fisk Rubber Co. for infringe- 

 ment of this patent which, it was alleged, covered the form 

 of mold used in the manufacture of Fisk tire casings by the 

 one-cure wrapped-tread process. 



This case has been before the courts for nearly four years, 

 and the two decisions in favor of The Fisk Rubber Co. are 

 of great interest to the tire makers of this country by whom 

 the one-cure wrapped-tread process, and the apparatus involved 

 in this suit, have been very extensively used. 



TRADE NOTES, 



William H. Scheel has annoutjced that he has recently added 

 to his already extensive line of compounding ingredients for the 

 rubber trade, new dry colors of exceptional excellence and has 

 already developed an active request for yellows, reds and greens 

 noted for being impervious to heat. Mr. Scheel is also ofifering 

 a zinc chromate chemically pure, both yellow and green, as well 

 as a line of English brilliant vermilion, and EngHsh Ver- 

 milion substitute. These new colors will compare favorably with 

 the general line which Mr. Scheel has been successfully offering 

 to the American rubber trade for the past twenty years. 



Ernest Jacoby & Co., whose headquarters are at 79 Milk 

 street, Boston, were incorporated March 1, 1913, for $25,000 under 

 Massachusetts laws. This concern is putting out a superior 

 English substitute made by Englishmen in its South Boston 

 factory. This house has an extensive connection throughout the 

 rubber trade. Its New York representative is Mr. W. F. Schling, 

 150 Nassau street. 



THE CRAWFORD SECTIONAL OVEN, 



It is claimed by many that temperatures can be more ac- 

 curately gauged in cases where steam is employed than where 

 other mediums are used. Recent experiences made in the gen- 

 eration of heat from gases have tended somewhat to negative 

 this view. The Crawford Sectional Oven, heated by an enclosed 

 gas burner, is said to be a very high type of oven construction 

 and an economical consumer of fuel. It is especially designed 

 for close temperature control. 



It is claimed to have been successfully used in the treating of 

 certain composition products, and to have successfully vulcanized 

 certain types of rubber goods. It is in extensive use among 

 manufacturers of electrical goods for drawing the moisture out 

 of fabrics prior to impregnation and heat, treating them in the 

 finishing process. In the latter case it is perhaps needless to call 

 attention to the fact that cotton carbonizes at a slightly higher 

 point than that at which water boils (212 degs. Fahr.). There- 

 fore successful impregnating compounds must be capable of heat 

 treatment at no higher temperature. 



The insulation of all these ovens is high and permanent. Their 

 sectional arrangements permit of rapid erection in cramped 

 quarters by unskilled labor and they are easily portable. 



The Crawford Sectional Oven is made by the Oven Equip- 

 ment & Manufacturing Co., of New Haven, Connecticut.
