IMPROVED RUBBER TUBING MACHINE. 



Tl I F. machine illustrated herewith may be used for making a 

 great variety of rubber goods, including carriage tires, 

 hose and for the preparation of stock for moulded goods. Very 

 compact and rigid and self-contained, it stands on a single, solid- 

 base plate, so that perfect alignment is assured. 



PARA ElrBBER SEED OIL. 



In a letter to the Planters' .Association of Ccylun, Professor 

 Dunstan, of the British Imperial Institute, calls the attention 

 of that body to the favoralilc opportunity that presents itself 

 just now for placing supplies of Para rubber seed kernels or 

 oil on the European market. In his communication, he points 

 out that the oil in question is suitable for use as a drying oil, 

 to replace linseed oil and similar drying oils, the prices of which 

 have been rising steadily of late and that while the Para rubber 

 seed oil would fetch aliout the same price, or perhaps a little 

 less than the linseed oil. the seed from which it is extracted 

 would be enhanced in value beyond present prices. The asso- 

 ■ ciation is requested to furnish information in regard to the possi- 

 bility of obtaining a steady and sufficient supply of the seed. 



Rubber Tubing Machine. 



The gears are machine cut, the pinion of steel and the large 

 wheel cast iron. The thrust from the screw, acts directly 

 against a head which is bolted fast to the cylinder of the 

 machine and having between the screw and the head a disc 

 of steel and bronze, which enables it to stand any pressure 

 without heating. The cylinder is equipped with a liner of cast 

 iron, which, when worn too large, can easily be replaced. Ample 

 provision is made for steam and hot water circulation around 

 the screw in the cylinder and the temperature of either end of 

 the cylinder can be kept independent of the other. The machine 

 is built in three sizes; the diameter of the smallest size screw 

 is 3'A inches, the second size 4J^ inches, and the largest size 6 

 inches. [Trenton Machine Specialty Co., Trenton, New Jersey.] 



A VERTICAL BRUSHING MACHINE. 



/'^'OMPACT, simple and efficient, the patent vertical brusher, 

 ^ illustrated herewith, is a machine the utility of which will 

 appeal to manufacturers of coated or water-proofed fabrics. It 

 is built with six cylindrical brushes, filled with stiff bristles and 

 so arranged that in passing vertically upward, between them, the 

 fabric is exposed to the active brushing effect of three brushes

on each side. If desired, steel bladed beaters or other cleaning 

 appliances may be used in place of some of the brushes. For 

 each brush, a dust chute is provided, through which, without 

 again coming in contact with the fabric under treatment or the 

 other brushes, the dust, lint, etc., is conducted into the dust 

 receptacle in the base of the machine, an air exhaust fan, con- 

 nected with the dust chutes, expediting its removal. 



The machine does good work by brushing and cleansing the 

 surfaces to be coated, on both sides, brushing coated goods in 

 connection with starch, cleaning cotton liners of soap-stone, etc., 

 and general brusli-finishing. The machine may be run in con- 

 nection with calender rolling machines as shown in illustration, 

 if tight hard rolls are needed, or provided with an ordinary roll- 

 ing up device. If it is only used to lay the goods off in loose folds 

 an overhead folding attachment may be used. The machines 

 built in various sizes as required. [Curtis & Marble Machine

CELLON— A NEW PRODUCT. 



Cellon is pcrliaps not exactly new in Europe as at least two 

 companies are said to be turning out goods. It, however, has 

 only appeared in sample form in the United States. It is as the 

 name indicates, a cellulose product, but radically different in form 

 from celluloid, acetyl cellulose, etc. In block or sheet form it 

 equals the best celluloid products and is non-inflammable. As 

 its cost in this form is high that will probably not be its first line 

 of commercial development. In solutions, however, it seems to 

 have a very wide field of application. For example, in proofing 

 leather it does away with the troublesome necessity of using 

 castor oil and one coating of it is said to equal ten of celluloid.
