free of charge with advertising matter imprinted with his busi- 

 ness name. The Court held, that while, as between the parties, 

 the contract was one of consignment ; as to creditors of the 

 bani<rupt, title to the goods passed to him, and they could not 

 be reclaimed from his trustee. 



A contract under which goods weVe furnished to an agent 

 for sale was construed, and it was held that the commissions 

 were based on the sum named in the price list, less 5. per cent 

 discount for cash. [The Federal Reporter, Vol. 233, page 489.] 



Daniel v. Electric Hose & Rubber Co. This was a suit re- 

 lating to a patent for a corrugated hose, the corrugations of 

 which appear to have been of structural value, in that they 

 strengthened the hose against lateral strain and increased its 

 wear. After the expiration of the patent, in 1889, the plaintiff 

 continued for some years to be the only manufacturer of hose 

 displaying these corrugations. Upon this sole ground, the 

 plaintiff claimed that it thereby acquired an exclusive right to 

 manufacture hose in that form, the form having become dis- 

 tinctive of its goods. The court said that, if this were the law, 

 it would follow that the patentee, after the expiration of his 

 patent, had he been the only maker of this hose for some year? 

 following, could, by his own act, turn his patent, which 

 the law limited to seventeen years, into a perpetual one, and 

 rejected the plaintiff!s application as an unwarranted extension 

 of the monopoly previously enjoyed under the patent. [The 

 Federal Reporter, Vol. 231, page 827.]

 use by others. [The Federal Reporter, Vol. 232, page 884.]

TENSILE STRENGTH CALCULATOR. 



A CLEVER device to assist in calculating the tensile strength 



/\ 



of rubber has been recently designed and copyrighted l)y 



Philip E. Young, New Bedford, Massachusetts. The "Tensile 

 Calculator," as it is called, is really a modified form of the slide 

 rule. and. as shown in the accompanying illustration, is extremely 

 simple both in construction and operation. It comprises a cir- 

 cular disk of white cel- 

 luloid, on which is su- 

 perposed one of lesser 

 diameter and transpar- 

 ent, serving as a support 

 for the annular trans- 

 parent disk that revolves 

 around it. 



The inner superposed 

 disk, being transparent, 

 shows graduations from 

 15 to 150, representing 

 the pull of the testing 

 machine in pounds. The 

 annular revolving disk 

 shows graduations from 

 .035 to .350 that represent the thickness of the test piece in deci- 

 mals of an inch. Coincident with the outer edge of the revolving 

 disk and marked on the larger disk are graduations from ,300 to 

 3,000. representing the tensile strength in pounds. 



-Knowing the thickness of the test piece and the pull of tlie 

 testing machine in pounds, the reading for tensile strength is 

 readily obtained by the following directions that are printed on 

 the reverse of the calculator. These read ; "Turn the transpar- 

 ent disk so that the thickness of the sample coincides with the 

 pull obtained on the testing machine. On the outer scale, oppo- 

 site the width of the sample, read the tensile strength."
