RUBBER STAMP PRICES REDUCED. 



Superintendent Metzler, of the Goodyear Tire and Rubber Co., 

 Akron, Ohio, was a recent visitor here. He renewed many 

 friendships with rubber men. Mr. Metzler was connected witli 

 the Hamilton Rubber Co. several years ago.

A delegation of Trenton public school teachers was taken on 

 a tour of inspection of some of the rubber mills a few days aigo. 

 The school board considered that in view of the important posi- 

 tion occupied by rubber manufacturing in Trenton it would be 

 well for the teachers ti> know something about the proces.s of 

 making it 



FIRST 41D IN ELECTRICAL SHOCK. 



The extended use of electricity in rubber mills, and the possi- 

 hility of accidents makes interesting the following tirst aid treat- 

 ment for electrical shock ; Raise the limp body by the ankles 

 with the whole weight re.-.ting on the neck, and then let it fall; 

 hammer the soles of tlie feet without removing the shoes; pull 

 forward the swallowed tongue. Such treatment frequently 

 brings the injured man to consciousness. [N. E. L. A. Bulletin.] 



THE Traun Rubber Co., Xew York City, has sent out a new 

 price list, showing a material reduction from former rates. 

 The various kinds of stamp rubber, including the different de- 

 grees of hard and soft, red, white and oil proof, are now quoted 

 at from 70 cents to $1.50 per pound for regular stock gage (14 

 Stubbs or 12 B. S: S.). Other thicknesses rolled to order at 

 special rates. Rubber dam, manufactured expressly for making 

 molds, is quoted at $1.45 per square yard. Printing type com- 

 pounds M inch in thickness now range from 40 to 80 cents a 

 pound. 



-Sponge rubber is offered at varying prices, According to 

 amounts ordered. Quotations here given are for single pounds, 

 with a considerable reduction on 10-pound and 25-pound lots, 

 and still heavier discount on 100-pound lots. For instance, 

 sponge rubber in 20 by 24 inch sheets, H, 3/16, % and H inch 

 thick, is quoted at $1.25 per pound; for 10-pound lots, the 

 price is $1.05 per pound; 2S-pounds cost 90 cents a pound, and 

 100-pound lots are listed at 85 cents. Similar reductions are 

 shown in quotations of other sponge rubber, the single pound 

 [.rices being as follows : 



One-half inch thickness, in slicets SI. 75 



Sponge rubber strips, 16 inches long, machine-cut from sheets, any 



width, ^g to -H inch thick 1.35 



Sponge rubber for artists' use, in slabs 14 by 16 inches, unskinned, 



J^, M or 1 inch thick 1.75 



.Sponge rubber, skimped, a-; above 1.85

AN IMSOLATED WIRE TESTING LABORATORY. 



More important than any other department in an in-ulated 

 wire or cable factory is the testing department NH expense is 

 spared in equipping it with delicate and accurate instrunlent^ 

 that instantly detect faults, and that measure with wonderful 

 exactness the insulation that the rubber covering affords. This 

 work is in the hands of expert electrical engineers, and records 

 for every foot of rubber covered wire are taken. While this work 

 was brought about prim:iri1y l>y insurance interests, the manufac- 



turers iiave not only met their specifications, but in their search 

 or perfection have bettered the requirements by a large margin. 

 So it comes about that laboratory, mill room and particularly 

 the testing room in instdated wire work arc keyed up to tin- best 

 and liighest efficiency. 



Speaking again of the testing room, its e<|uipment, in i)art, 

 consists of galvanometers and Wheatstone bridges, high \o'iage 

 testing sets, machines for testing rubber, and faliric :in(l .\.irn 

 testing machines.
