THE INDIA RUBBER WORLD 



[September i, 1905. 



THE "dime" screen DOOR CHECK. 

 For the prevention of slamming of screen doors, an ingenious 

 little device has been invented which is partially illustrated by 

 the engraving herewith. It consists of a bumper of molded 



rubber attached by a screw 

 to the door jamb, and a 

 plunger of metal rigidly at- 

 tached to the screen door. 

 The door is checked three 

 inches from the closing 

 point, when the rubber 

 bumper hangs in a vertical 

 position. The coming in 

 contact of the rubber bum- 

 per and the metal plunger 

 changes the position of the 

 former, as shown in the cut 

 herewith, the effect being 

 to check the door and thus allow it to close without slamming, 

 after which the rubber bumper resumes its vertical position. 

 A patent has been applied for. The device is intended to retail 

 at 10 cents. [The Caldwell Manufacturing Co., Rochester, 

 New York.] 



Marvin's emergency fire hose mender. 

 It often happens that the delay caused by the bursting of hose 

 at a fire results in much loss of property. It has been necessary 

 hitherto that the pressure be cut off and the flow of the water 

 discontinued while the hose was being mended or a new section 

 substituted, it being impracticable to apply an ordinary sleeve 



to bursted hose while 

 ^^[ fj-^^ the water continues to 

 flow from the leak un- 

 der fire pressure. The 

 new device described 

 here can be quickly ap- 

 plied to hose at any time, 

 and when under full fire 

 pressure. It consists of 

 FiQ- 1. a casing adapted to be 



clamped to the side of the hose and containing on one side an 

 orifice which may be left open while the hose mender is being 

 applied, thus allowing the free escape of water from the 



;

bursted portion of the hose until the mender is securely in place. 

 This orifice is provided with a valve which may be closed after 

 the mender is in position. Figure i gives a general view of the 

 clamp; Figure 2 shows it 

 in process of being applied, 

 the valve being left open for 

 the escape of water mean- 

 while ; Figure 3 illustrates 

 the method of finally clos- 

 ing the leak ; and Figure 4 fig. 4. 

 the repair complete. The hose in a bursted condition is apt to 

 be swelled somewhat, rendering it difficult to bring the hose 



mender down into its final position. This is obviated by means 

 of a double link on one end, which has a longer reach, as shown 

 in Figure 2. By means of this feature, the two halves of the 

 hose mender can be brought gradually together, and when it is 

 firmly secured at both ends the valve is closed, as shown in 

 Figure 4, and the repair is complete. This device is the subject 

 of United States patent No. 763,191. It is made of brass, pol- 

 ished to a nozzle finish, and weighs only about 7 pounds. It is 

 understood to have been well received by fire department offi- 

 cials. [J. B. Marvin, Frankfort, Indiana.] 



COMBINATION WATER BOTTLE AND 



SYRINGE. 

 The Combination bag illustrated in 

 the accompanying illustration, as its 

 name implies, may be used either as a 

 water bottle or a fountain syringe bag. 

 The conversion from one use to the 

 other requires only the interchanging 

 of the stopple and the hard rubber 

 syringe connection. As will be seen, 

 the bag has a top outlet, instead of the 

 syringe connection being made at the 

 bottom, as in the case of other combi- 

 nation bags. This article may be ob- 

 tained in either white or slate colored 

 rubber, and at an extra price, in red- "^ ' 



In sizes, it is supplied in i, 2. 3 and 4 quarts. [Tlie B. F. 

 Goodrich Co., Akron, Ohio.] 



THE LATEST ARTIFICIAL RUBBER. 



[a press dispatch.! 

 Bknion Harbor. Mich., July 16.— Dr. Henry V Tutton, well 

 known surgeon, and John Smith, a chemist, have discovered a pro- 

 cess for manufacturing rubber. Success has been attained after 

 live years of experimenting. It can be manufactured and sold at 

 a profit at .^o cents a pound. Me.\-,can rubber costs $1.25. A 

 stock company will be organized and the material manufactured 

 in large quantities. The process 's kept a secret. 

 fANSWER TO AN INQUIRY]. 



T^O THE Editor of The India Rubber World ; While 



^ Mr. Smith and myself have succeeded in extracting (not 

 making) a peculiar gum from certain of our native herbs, which 

 when properly treated possesses many of the characteristics of 

 rubber, such as elasticity, tensile strength, vulcanizing proper- 

 ties, and so forth, we are in no position to state what commer- 

 cial value the product may prove to have, it being as yet mere- 

 ly in the experimental stage. 



It is amusing to read the comments and wild statements ap- 

 pearing in some of the newspapersconcerning this matter. We 

 are simply experimenters and investigators, and have never even 

 contemplated the formation of a stock company to exploit some- 

 thing of the value of which we are ourselves ignorant. Not one 

 cent of anybody's money but our own has been used by us so 

 far, and we are neither of us inclined to join the already too 

 great army of "grafters." 



That we have something which will prove to be commer- 

 cially useful, we firmly believe, though with our exceedingly 

 limited laboratory facilities, it may be one, two, or even three 

 years before we can positively tell for what purpose. 



It is unfortunate that merely showing a small piece of our 

 product should have raised such a "tempest in a teapot," as 

 it has undoubtedly done, and it is doubly unfortunate for the 

 reason that it has been the means of handicapping us in our 

 experiments and bringing us into disrepute unjustly. 



Vours in a spirit of true investigation, H. v. tutton.
